Safflower seed cleaning machine and determining the rotational speed of its supplying roller

The article describes zones with a predominant type of melioration depending on the territorial location of the land being improved. It provides a brief classification of channels based on their structural features, cross-sectional shape, flow capacity, and technical and operational characteristics. Channels are the main elements of meliorative systems. Ensuring the quality of channel operation with the required flow capacity guarantees the effective operation of the entire meliorative system. The typical deformations of channels that arise during operation are described, as well as factors that affect their flow capacity, such as sedimentation, siltation, and vegetation growth, including shrubs and small trees. Channel cleaning machines used for cleaning and restorative work on meliorative system channels are presented, along with their design features for cleaning channels of various types and cross-sections. Channel cleaners are described that operate as both periodic and continuous action machines, which most effectively and qualitatively clean the bottom and slopes of channels in various meliorative systems. The article also explains how the efficiency of channel cleaning and subsequent quality of the meliorative system can be increased by using different sets of channel cleaning machines, including various machines with different working tools, sizes, and quantities. The choice of the number of machines is directly related to technical and economic indicators: the use of a large number of machines may be economically impractical, while using a minimal number of machines will not provide the required cleaning. Therefore, it is important to choose the optimal number of machines of different sizes and shapes to form a separate set.

“…In addition to cotton and grain growing, great attention is being paid to the development of vegetable growing, policing, horticulture, animal husbandry, beekeeping, and fishing in the republic's agriculture [6][7][8][9][10][11][12][13][14]. Since cotton and grain were the dominant crops in Uzbekistan in the past, scientific and research work was carried out on the development of technologies and machines for tillage, planting, inter-row cultivation and harvesting or picking, which are mainly used in their cultivation, and a number of technologies and machines were created [15][16][17][18][19][20]. But today, vegetable crops, including carrots, onions and turnips, are mostly hand-planted because their seeds are small.…”

Development of a seeder design for precise sowing of carrot seeds on a ridge

Among vegetable crops, carrot is one of the main agricultural products for domestic consumption and export in Uzbekistan. For this reason, great attention is paid to its cultivation as a main and repeated crop after grain. Today, in order to earn additional income from the land twice, carrots are planted in the main part of the grain-free areas of farmers and peasant farms. With the increase in the area planted with carrots, there was also a demand for seed drills. Taking this into account, a seeder was developed that sows carrot seeds in the exact amount in the specified planting pattern on the paddy field. In one pass of the seeder, flattening the top of four furrows to form a bush, 5x5 cm when the distance between seeds is 60 cm, 6x6 cm at 70 cm spacing and 8x8 cm at 90 cm spacing are planted 1.0-1.5 cm deep. Accordingly, the working equipment of the seeder installed as a form moving.

“…The world has taken comprehensive measures to decrease the manual work and energy expanses in agricultural production, resources saving, growing crops based on developed technologies and creating high-performance agricultural machinery, including less-energy technological processes in ploughing fields [4][5][6][7][8][9][10][11]. Particular attention is paid to the development of technical means to ensure quality indicators [12][13].…”

Determination results of disc plough hang mechanism and support disc parameters

In recent years, due to the steadily crept of implementaton of energy and resource saving technics and technologies as well machines in agricultural branch, the utilising of ploughs in the main tillage (ploughing) in the form of spherical disks, ie the working body. In this article we present the results of experiments and research to substantiate the distance from top to bottom side H1 of support disc of disc plough to the bottom side mounting area of the suspension device and the diameter of the support disc of the plough. This means that the distance from the support disc to the lower mounting points of the suspension device should be in the range of 650-700 mm to ensure that the disc plough is well immersed in the ground and the driving depth is stable and the required transport clearance is maintained. Diameter of the support disc should be in the range 500-550 mm, so that the width of coverage is stable.
