Air-pressure auto-excitation type vibrating subsoiler

Abstract

Provided is an air-pressure auto-excitation type vibrating subsoiler. The subsoiler comprises a frame, multiple subsoiler shovels and an air pressure adjusting system; the frame includes a cross girder A, a cross girder B, depth limiting wheel supporting arms and suspension arms; a depth limiting wheel is arranged under each depth limiting wheel supporting arm, the cross girder A is arranged parallelly to the cross girder B, an air cylinder A used for adjusting the height of the cross girder A is also arranged between the cross girder A and the cross girder B, the subsoiler shovels are installed on the cross girder A, and the suspension arms are installed on the cross girder B; the subsoiler shovels are connected to the cross girder A through connecting arms capable of swinging up and down, air cylinders B are arranged on the connecting arms, and the` air pressure adjusting system includes an air pressure part and two air pressure control parts, wherein the two air pressure control parts are used for controlling the working states of the air cylinder A and air cylinder B respectively; an ultrasonic probe is arranged on the cross girder B and also connected to a central control system. By adopting air-pressure type auto-excitation vibration, fast adjustment of the rigidity of a vibration source can be achieved, the adaptability of the vibration source to different degrees of soil resistance is improved, and therefore the subsoiling effect is better improved.

Description

technical field [0001] The invention relates to an agricultural loosening equipment, in particular to a pneumatic self-excited vibration subsoiler. Background technique [0002] The load and rolling of the farming machinery caused serious soil compaction, and years of shallow plowing and rotary tillage under the same depth of soil formed a solid plow bottom layer on the cultivated land. The subsoiling process of the subsoiler is mainly to use the subsoiler to loosen the soil, deepen the plow layer without turning the soil, effectively break the plow bottom layer, adjust the soil three-phase, create a plow layer structure with both virtual and solid, reduce soil erosion, and improve soil storage. water drought tolerance. The traditional vibratory subsoiler adopts the forced vibration mode, and the power of the power output shaft of the tractor is converted into the up and down vibration of the vibrating parts connected with the frame, and the vibrating parts are mainly eccen...

AI Technical Summary

Problems solved by technology

Existing self-excited vibratory subsoiling machines mainly use changes in soil surface unevenness and soil resistance to arouse the vibration of elastic elements such as springs and elastic materials to complete vibratory subsoiling operations, and the self-excited vibration of the spring excitation source is due to the constant spring stiffness. , to deal with the limited range of soil resistance, poor adaptability, and even the failure of self-excited vibration
