Soil layered rotary tillage test device

Abstract

The invention relates to a soil layered rotary tillage test device. The device comprises a rotary tillage knife roller rotation speed adjusting device, a soil crushing knife roller rotation speed adjusting device and a soil crushing knife roller position adjusting device; power accesses the rotary tillage knife roller rotation speed adjusting device through a speed-up gear box, and then the poweris transmitted to a multistage gearbox which can adjust the reduction ratio through a shift handle so as to control different output rotation speeds; the soil crushing knife roller rotation speed adjusting device absorbs oil through an oil tank by means of a hydraulic pump, flow of hydraulic oil is controlled through a servo valve, the hydraulic oil is input into a hydraulic motor to control the rotation speed of the motor, and then the rotation speed of a soil crushing knife roller is adjusted; according to the soil crushing knife roller position adjusting device, the vertical position of thesoil crushing knife roller driven by a crank swing block composed of an inner sleeve and an outer sleeve which are connected through a lead screw is adjustable, and the soil crushing knife roller isdriven by a left ball screw and a right ball screw to move left and right. Accordingly, the biaxial spacing and the rotation speed can be adjusted at any time, and the device is applicable to soil layered rotary tillage work of a multiple rotary tiller for outdoor fields.

Description

technical field [0001] The invention relates to a soil layered rotary tillage test device, which belongs to the technical field of agricultural machinery. Background technique [0002] Soil tillage is the most basic and important link in agricultural mechanized production. The quality of tillage operations is directly related to the quality and output of subsequent crop planting and harvesting. With the improvement of farmers' requirements for production efficiency, domestic soil tillage machinery is gradually tending to compound operations, which not only greatly reduces the time-consuming and labor-intensive problems of repeated operations on the same field, but also reduces soil compaction and operation power consumption. The application area is increasing year by year. For this reason, farmers' demand for compound farming machinery has also risen sharply. [0003] In order to reduce the cost and reduce the number of design reworks, the design of tillage machinery is ge...

Problems solved by technology

[0004] Although the above two types of test benches can solve the energy consumption test of rotary tillage machinery, they are only suitable for the test of rotary tillage or plowing machinery with single-axis rotation. For the two-axis rotary tillage machinery, on the one hand, the distance between the two axes and the speed cannot be adjusted online at any time. and other parameters, which lead to the impossibility of research on the energy consumption and operation quality of each axis of the compound rotary tillage machine; The error between the results is large
