A test bench for six-component force testing of oblique submerged soil rotary tiller

Abstract

The invention provides a six-component force test bench for an inclined submerged rotary cultivator, and the test bench comprises a test platform, a detection mechanism, and a controller, and the testplatform comprises a rotary cultivator frame, a hydraulic rod, a motor, and a rotary cultivation cutter roller. I-shaped clamps are arranged on the two sides of the rotary cultivator frame respectively, and the two ends of the rotary cultivation cutter roller are installed in the I-shaped clamps through bearings respectively; one end of the hydraulic rod is connected with the rotary cultivator frame; an output shaft of the motor is connected with the rotary cultivation cutter roller. The detection mechanism comprises a plurality of force sensors, and the force sensors are installed on the inner walls of the grooves in the two sides of the I-shaped clamps correspondingly and used for measuring the stress of the contact positions of the I-shaped clamps and the rotary cultivator frame; and the controller is connected with the hydraulic rod, the variable-frequency and variable-speed motor and the force sensors. The device can conveniently and effectively simulate forward and backward rotation rotary cultivation tests under different cutter roller soil-submerging depths and rotating speeds, and can detect the stress condition of the rotary cultivation cutter roller during working.

Description

technical field [0001] The invention belongs to the field of agricultural engineering research, and in particular relates to a six-component force test bench for a slanted submerged soil rotary tiller. Background technique [0002] Oblique rotary tillage absorbs the advantages of disc plow, common plow and rotary tiller, and is a new type of rotary tillage. This working method can not only reduce the power consumption of crushing soil, but also ensure the smooth turning and throwing of soil. When tilting the rotary tillage, the soil resistance on the rotary tiller includes the resistance of cutting soil, the resistance of tearing soil, the friction resistance of blade and soil, the deformation resistance of cut soil and the resistance of throwing soil, etc. In addition, because the oblique rotary tillage requires sequential cutting, the arrangement of the knife rollers all adopts the same left machete, which increases the axial side reaction force. As a result, both ends o...

AI Technical Summary

Problems solved by technology

In addition, since the oblique rotary tillage requires sequential cutting, the arrangement of the knife rollers all adopts the left curved knife in the same direction, which increases the axial side reaction force

As a result, both ends of the shaft are often easily broken, and the machine cannot work normally, seriously affecting the progress of rush harvesting and broadcasting during busy farming seasons
