In recent years, the improvement of the technological process of soil treatment is based on the use of working bodies with a curved shape of the working surface, which can increase the agro-technical and reduce the energy-intensive parameters of soil treatment. Agricultural units with disk working bodies are one of the most common machines in agriculture. The article presents a design scheme of a disk working organ with a working surface made along the Archimedes ’ spiral. Expressions are obtained for designing the working surface of the disk with the specified initial parameters.

The article proposes to use the Euler equations to describe the motion of a stationary flow in the cleaning zones, which allows determining the laws of pressure, density and velocity distribution along the arc of contact of a moving layer of raw cotton with a mesh surface in the process of impact impact with spikes on the pulp. It has been established that the pressure, densities and flow rates along the cleaning arc as a result of hammer spikes vary in steps, with a decrease in pressure and density and an increase in the flow velocity along this arc.

Abstract The purpose of the study is to substantiate the relative position of the working bodies of a combined machine for non-fall tillage of winter crops. The design scheme and the principle of operation of the combined machine are given. The basic principles and methods of classical mechanics, mathematical analysis and statistics were used in this study. It is established that the most optimal design scheme of a combined machine for non-tillage of the soil and its preparation for sowing of repeated crops is considered to be a scheme consisting of non-tillage cases with crushers, a battery with cut-out spherical disks and a roller. According to the results of theoretical and experimental studies, it was found that with a longitudinal distance between the shaft-free bodies of 40 cm and a transverse distance of 90 cm, a longitudinal distance from the toe of the ploughshare to the center of the support wheel of 50 cm and a longitudinal distance from the toe of the ploughshare of the shaft-free body to the axis of rotation of the cut-out spherical disk of 120 cm, a longitudinal distance from the axis of rotation of the cut-out spherical disk to the center of the roller of 75 cm, high-quality tillage with minimal energy costs is provided.

From time to time researcher developed different types of electricity generating device s. Because electricity and home lighting are considered essential for a country’s economic and social developments. GH24 bio generator is a device that converts the chemical energy of waste organic compound into electricity (light) using naturally occurring microorganisms found within the waste. 40 cm height, 20 cm width, 60 cm length, and 3.5 Kg mass prototype was developed. The prototype was composed of four reactor chambers, sample inlet pipe, bridge, gas outlet pipe waste disposal pipe and upper and bottom protective layer. The greenness, simple operation and effective design are characteristic of the devices. Prototype testing was performed using a liquid dough as a sample. A maximum of 3.403 V was generated when the GH24 bio generator prototype operated with 3.5 L of waste liquid dough sample. This renewable energy is given light for 10-12 hr. using one light bulb. The device could be used as an important source of light for people living in off-grid access to electricity area. Other benefits of the device is used to minimizing the health and environmental impact of fuel-based lamps by replaced it.

Abstract. Testing was conducted at a western commercial cotton gin to evaluate the effect of humid air moisture addition on fiber quality, bale value, and operating costs; when applied at the gin stand feeder conditioning hopper and battery condenser lint slide. Two tests each with 19 conventional modules of upland cotton were conducted over two consecutive days. The moisture treatments included feeder hopper moisture on or off and lint slide moisture on or off, resulting in four treatment combinations: 1) no moisture added (No Addition), 2) moisture added at the feeder hopper only (Hopper Only), 3) moisture added at the lint slide only (Slide Only), and 4) moisture added at the both the feeder hopper and lint slide moisture (Hopper+Slide). Results showed that seed cotton moisture content at the gin stand was about 0.1 percentage points higher when moisture was added at the feeder hopper and lint moisture content in the bale was about 0.9 percentage points higher when moisture was added at the lint slide. Adding moisture at the feeder hopper resulted in small, but significant (p-value = 0.05), improvements in HVI length [+0.21 mm (0.008 in.)], uniformity (+0.16 percentage points), and strength (+0.25 g/tex), and AFIS length [+0.4 mm (0.016 in.)] and short fiber content (-0.52 percentage points). However, fiber yellowness also increased (+0.12 +b) when moisture was added at the feeder hopper. Adding moisture at the lint slide had very little effect on fiber quality. Moisture addition at either location did not significantly affect spinning performance or yarn quality. Lint produced with moisture added only at the feeder hopper had the highest average value [$1.254/kg (56.88 ¢/lb)] and lint with moisture added only at the lint slide had the lowest value [$1.234/kg (55.98 ¢/lb)]. Bales produced with added moisture were heavier, 9 kg (20 lb) heavier on average for the Hopper+Slide moisture addition than for No Addition. Bales produced using moisture addition not only contained more moisture, but also more lint. This could be due to easier bale pressing, which was supported by measurements which showed that about 2 kW less press power was required to press bales with moisture added at the lint slide. Moisture added at the feeder hopper resulted in the greatest overall increase in value over the value of cotton ginned with no moisture addition, more than $32,000 when extrapolated over 10,000 bales. The moisture addition treatments required more energy to produce bales, mainly due to the additional natural gas required for air humidifying equipment. However, since bales with added moisture contained more dry lint resulting in fewer bales pressed for the same amount of dry lint in bales produced with no moisture addition, savings in bale packaging materials and labor costs made operating the moisture systems slightly less expensive than not, up to about $1400 less for 10,000 bales with the Hopper+Slide moisture addition. Although the results showed little impact on cotton quality by adding moisture, the subtle differences and heavier bales containing more lint could have a significant effect on the value to a producer over an entire cotton crop or to a gin over an entire season.
