Rotary working body of the tillage machine

Abstract

In the process of designing tillage and other agricultural machines, the main problem is to ensure the quality and optimal energy consumption of technological operations. For existing rotary and milling tillage machines, the main indicators of the quality of work and the energy intensity of the process depend on the kinematic, structural and technological parameters, the ratio of the angular rotational speeds of the disks, translational speed, diameter of the working body, number of cutting elements, depth of cut, ridge height, etc. The ridging of the bottom of the furrow is one of the important agrotechnical indicators of the operation of rotary tillage machines. The height of the ridges should be no more than 20% of the tillage depth. This requirement imposes certain restrictions on the choice of parameters and operating modes of rotary tillage machines. The purpose of the study is to establish the laws of the influence of kinematic and structural parameters of a double-disc rotary working body on the quality and energy intensity of soil cultivation. The object of the study is the process of cutting soil by an active-passive rotary working body. The influence of setting and design parameters on the energy intensity of the working process of a double-disc rotary working body is determined. Power characteristics of the working body, leading to the destruction of the ridge of the bottom of the furrow are defined. Range of adaptive high-speed regulation of the working process of a double-disk rotary working body is established. The energy parameters of the working process of the combined double-disc working body are assessed. It was found that the specific energy consumption of rotary tillage by a double-disc working body is reduced to 20-30% compared to milling. Evenness of the furrow bottom up to 80% is ensured.
