Theoretical investigation of increasing efficiency of combine harvester operation on slopes

Abstract

Intensification of work processes of agricultural machinery is a part of important national economic problems of increase of agricultural production. One way to increase intensity is to reduce grain loss when working with combine harvesters on slopes of fields. In the lateral pitch of the harvester there is redistribution of the grain heap on the screen width and cleaning sieves. The diagram of linear distribution density of the grain heap on the screen width and cleaning sieves is transformed from a uniform type of rectangle to irregular: the type of triangle, trapeze without a shift or with a shift in the direction of the pitch. We have large losses of grain, because of the uneven linear distribution density of the grain heap on the screen width and sieves. The article offers various methods and devices, which have certain advantages and disadvantages, to reduce grain loss. One of the promising directions to reduce grain loss is the dynamic method, which uses a specific device as a set of hinged-lever units. However, one of the major drawbacks of these devices is the equality of oscillation frequency of the longitudinal and lateral pitch. The adopted working hypothesis and studies of the process kinematics and dynamics will define the main structural and technological parameters of the cam mechanism to align the linear distribution density of the grain heap on the screen width and sieves.

Implementation of government support measures for reclamation as an incentive for the development of the agricultural industry: Experience of the Republic of Tatarstan

“…The key role should be assigned to Kazan State Agrarian University, whose team has more than 100 years of experience in training hydro-meliorators, forest meliorators, hydrobuilders, land surveyors, engineers, machine operators and other specialists. The agrarian university has staff, scientific, methodological and material and technical base, which must be preserved, supported and improved [14][15][16].…”

Justification of parameters of vacuum pumping means with pulsating active flow for cattle farms

“…An integral part of the agro-industrial complex is the production of high-quality agricultural products, which is associated with the mechanization of technological processes [1][2][3][4]. Currently, work is underway to find effective technical solutions to improve these processes [5][6][7][8].…”
