It is known that, in recent years, great attention has been paid to the cultivation of oilseed crops such as sesame, peanuts, sunflower, soybeans, and safflower in our republic. Because they are widely used in the manufacture of confectionery products, in medicine and industry, and their seeds are widely used in animal husbandry. Based on the above, the Namangan Institute of Engineering and Construction developed a multi-functional (digging, de- stalking, sorting and loading) peanut harvesting machine [1-14]. METHODS AND MATERIALS. In exploring the kinematics of the peanut harvesting machine’s scraper were used thelaws ofhighermathematics andtheoretical mechanics. RESEARCH RESULTS. The speed of the belt conveyor also plays an important role in exploringthekinematics of thecreated peanut harvestingmachine’s scraper During operation, the peanut balls, which are squeezed by the belt conveyor, are moved forward by the machine and up and back by the belt conveyor (Figure 1). We determine its absolute speed according to thefollowing expression. 126 INTERNATIONAL MULTIDISCIPLINARY JOURNAL FOR RESEARCH & DEVELOPMENT SJIF2019:5.2222020:5.5522021:5.6372022:5.4792023:6.5632024:7,805 eISSN:2394-6334 https://www.ijmrd.in/index.php/imjrd Volume12,issue05(2025) Figure 1.Scheme fordetermining the speed ofa belt conveyor Here V- istheforward speed ofthemachine, m/s; -is thespeed ofthebelt conveyor, m/s. We determine the angle of the relative to the horizon of the absolute speed of the peanut’s ball. A ccording to thescheme shown inFigure 1 For the pods to be completely and easily dug out, the velocity Va must be directed vertically, as it were γ=90º.Taking thisinto account, from expression (2) weobtain the followingexpression And from this It follows that itshould be. Taking into account q,theslipof thetapetakes theform of expression(4). (5) The speed of a belt conveyor for transporting goods depends on the forward speed of the machineand theslip coefficient ofthe belt. The scraper moves in a complex manner during operation, i.e., it moves forward and rotates around its axis together with the machine [15, 16]. The equations of motion of its blades in the XYZ coordinate system have thefollowing form (Figure 2). 127 INTERNATIONAL MULTIDISCIPLINARY JOURNAL FOR RESEARCH & DEVELOPMENT SJIF2019:5.2222020:5.5522021:5.6372022:5.4792023:6.5632024:7,805 eISSN:2394-6334 https://www.ijmrd.in/index.php/imjrd Volume12,issue05(2025) Figure 2.Scheme forthestudy ofthekinematics oftheslider Here t is thecar's travel time, s; β –theangle ofinstallation ofthe damper relativeto thehorizontal, º; -the radius ofthepoint ofview ofthewiper blade, m, ωt –theangle ofrotation of thescraper(this angle is measured clockwise from theaxisOX), º.

Taking into account theexpressions(9) -(14), theseexpressions have thefollowing form. In this It is clear from expressions (17) and (19) that the velocity of the point of view of the impeller vanes isvariable, whileits acceleration is constant and equal to thecentripetal acceleration. CONCLUSION. The conducted studies have shown that the speed of a belt conveyor depends on the forward speed of the machine and the belt slip coefficient, showed that the speed of the point of view of the blades of the shovel is variable, and the acceleration is constant, and the tendency to thecenter is equal to theacceleration.
