The data on the gross harvest of tubers in the Russian Federation are given: approximately 71% of potatoes are produced by the population, 17.4% by agricultural enterprises and 11.5% by farms. It is noted that in the industrial production of potatoes, negative impacts on the soil are associated with crushing and removal of the fertile soil layer, which arise in the process of extracting root crops by the digging and separating working bodies of the harvesting machines. It is proposed to use ultrasonic action on root crops for cleaning them from soil impurities. It was determined that in order to intensify the process of cleaning tubers by ultrasonic action during harvesting, it is necessary to provide operating and technological parameters (frequency of ultrasound oscillations f1 = 48 kHz, vibration intensity S = 42 W/cm², exposure time t = 90 s) of ultrasonic equipment, which will ensure the completeness purification is not less than 84.7%.The results of comparative studies on the intensification of the cleaning of potato tubers allow us to conclude that, regardless of the mass and type of pollution, the greatest positive effect of ultrasonic exposure is observed when processing tubers, the completeness of cleaning of which is on average 13-20% higher.

The Impact

The quality of the separation of root crops, onions and potatoes is known to primarily depend on the cultivation conditions. As a rule, these cultures are cultivated in mechanically light soils in order to improve the quality of separation, as well as to reduce the traction resistance of the harvester when extracting the root crops from the soil. When harvesting the root crops, it is very important to maintain the soil in a loose (light) state to improve the quality of the separation. Due to the fact that in digging up the root crops, there is a joint flow of strong soil lumps to the separating working bodies, which are difficult to separate on the slit working bodies of the harvester, which increases damage to the root crops when interacting with the soil lumps, the commercial quality of the products is subsequently deteriorated. The existing potato harvesters damage the commercial products as a result of the interaction of the potato tubers with each other, with the working bodies and with the soil lumps. However, the greatest percentage of damage to potato tubers occurs as a result of their interaction with the working bodies of the harvester. Field studies were conducted to determine the places of the greatest impact of the individual working bodies of the potato harvesters and to carry out subsequent actions for the elimination of these negative impacts in the design of the harvesters. This article presents a methodology for conducting field studies on the assessment of the impact of the working bodies on the scale of damage to potato tubers when harvesting. The results of the comparative studies of the impact of the working bodies of modern potato harvesters, which damage the potato tubers as a result of the interaction with them are presented. We have determined that the greatest scale of impact on the potato tubers during the mechanised harvesting is observed as the transition from the main elevator to the secondary separation devices takes place, irrespective of the design and technological scheme of the harvester, and reaches its minimum value from 6.5 N for the Bolko harvester to 21 N for the AVR-Spirit-6200 harvester.

Ultrasound Effect

The most promising of the known ways to reduce the content of soil bolsters during machine harvesting of tuberous roots should be considered pre-harvest moisturization of the soil layer in which the tuberous root are located. This significantly reduces the content of soil impurities in harvested tuberous roots. However, atomized spray of water, even under pressure, is not able to ensure its instant flow to the depth of tuberous roots and, moreover, to moisten the soil to the state that provides further intensification of the process of separation of tuberous roots from soil bolsters that are comparable to them. To eliminate this defect, it is necessary to provide an intensification of the water spraying process by one of the methods of physical influence, which provides instant soil moisture to the depth of tuberous roots. The article presents instrumentation for research of technological parameters of ultrasonic treatment on the quality of the cleaning roots crops from soil impurities, the method and results of laboratory studies of ultrasound effect on the cleaning process of potato tubers of the "Red Scarlet" variety and carrot root crops of «Shantane» variety . The optimal parameters of ultrasound influence that intensifies the process of cleaning root crops from soil impurities were determined. The results of comparative laboratory studies of cleaning potato tubers and carrot root crops from various root crops on the physical and mechanical composition of soil impurities (sandy loams and loam soils) allow us to conclude that the best indicators of intensification of ultrasonic influence with increase in the completeness of cleaning, despite the weight and type of contamination, are observed when processing carrot root crops, the completeness of cleaning is on average higher by 13...20 %.

Significant Factors

It was found that the extraction of a tuberous heap, namely potatoes, with a digging working body with a movable frame, has the most significant drawback, which is that when the depth of the burrowing share tip is changed, the angle of its inclination changes, which negatively affects the chipping of the soil layer and leads to the deterioration of the transportation of the excavated soil layer to the separating working bodies, for which it is necessary to determine and clarify the main technological and design parameters of the developed intake plough share for digging / picking up root crops and bulbs due to the fact that potato tubers and onion bulbs have different size and mass and physical and mechanical properties. A method has been developed for determining the amount of supply of a heap of onion sets from the surface of the digging share to the separating working bodies, the required soil moisture necessary for research. The methodology and results of experimental studies to determine the decrease in the content of soil impurities in the gathering heap of onions are presented, the main statistical characteristics of the experiment are reflected. Based on the results of the screening experiment, significant factors have been established that have a decisive effect on the selected optimization criterion: spring preload, determined by the spring length and the forward speed of the digging share. It was found that the minimum possible amount of soil impurities when extracting onions from the soil is 24.8%. It depends on the values of the investigated factors, values that should be set in the interval: the length of the spring L_PPR=0.02-0.04 m and the speed of the moving share v_L=1.2-1.4 m/s.

The research objective is to improve the quality of soil loosening using combined working bodies for surface moisture-retaining soil cultivation. The efficiency of accumulation and conservation of precipitation in the autumn-winter period depends on the method of post-harvest soil cultivation. One of them is the autumn surface water-retaining treatment, which makes it possible to increase the efficiency of the processes of accumulation and conservation of moisture due to the deeper loosening of the cultivated soil layer. During loosening and mulching, the top layer of the soil contributes to the accumulation and preservation of moisture not only in the upper but also in deeper soil horizons. However, the used tillage tools do not fully solve the problem of the high-quality performance of surface moisture-retaining soil cultivation. The article presents the results of studies of the degree of influence of geometric and technological parameters of the additional active cultivator on the quality of surface tillage. Based on the results of the research carried out, the technological process of performing the surface tillage operation has been improved and combined working bodies have been developed for its implementation.

One feature of harvesting seed onions is that the impurities of the onion-soil pile coming from the digging executive devices to the separating executive devices contain soil lumps that are similar in size with the seed onion bulbs and hard to separate at the slotted (bar elevators, screens) executive devices (M. Tauseef Asghar, 2014). This problem is most urgent when collecting seed onions from the rolls, because together with the bulbs the separating executive devices receive the soil layer loosened by the digging executive devices during the first phase of harvesting seed onions, the fractional composition core of which is soil lumps similar to bulbs and hardly separable on slotted executive devices. This circumstance is explained by the fact that after the soil layer is undercut together with the saleable produce, a significant amount of soil lumps, hardly separable on the separating executive devices and causing damage to root crops and bulbs during their interaction, arrives to the separating executive device. In addition, separation of soil lumps on slotted executive devices (bar conveyors and screens) occurs according to dimensional properties and this does not solve the existing problem – separation of soil lumps comparable in size with seed onion bulbs. Consequently, to ensure qualitative indicators of harvesting seed onions, namely, the separation completeness of the bulbs from soil impurities, it is necessary to ensure a reduction or complete elimination of the flow of soil lumps to the separating executive devices at the second harvesting phase.

The roller and sieve machines most commonly used in Russia for the post-harvest processing of root and tuber crops and onions have a number of disadvantages, the main one being a decrease in the quality of sorting due to the contamination of working bodies, which increases the quantity of losses during sorting and storage. To obtain high-quality competitive production, it is necessary to combine a number of technological operations during the sorting process, such as dividing the material into classes and fractions by quality and size, as well as identifying and removing damaged products. In order to improve the quality of sorting of root tubers and onions by size, it is necessary to ensure the development of an automatic control system for operating and technological parameters, the use of which will eliminate manual sorting on bulkhead tables in post-harvest processing. To fulfill these conditions, the developed automatic control system must have the ability to identify the material on the sorting surface, taking into account external damage and ensuring the automatic removal of impurities. In this study, the highest sorting accuracy of tubers (of more than 91%) was achieved with a forward speed of 1.2 m/s for the conveyor of the sorting table, with damage to 2.2% of the tubers, which meets the agrotechnical requirements for post-harvest processing. This feature distinguishes the developed device from similar ones.

The aim of the research is to improve soil tillage quality using combined working bodies in surface cultivation. There are various designs of combined tillage units including passive cultivators and active rotor-tooth working bodies cultivating land. However, an analysis of design and technological parameters of modern cultivators shows that they have a cumbersome design, required much metal and their quality indicators do not meet soil cultivation requirements. The article presents results of the studies on the influence of geometric and technological parameters of an additional battery of needle discs on land tillage quality. Using the research results, the land tillage has been improved and combined working bodies have been developed.
