Self-induced vibration anti-drag subsoiler

Abstract

The invention discloses a self-induced vibration anti-drag subsoiler. The subsoiler solves the problems that existing subsoilers have complicate structures, high drag, and poor adaptability, and are easily damaged. According to the technical scheme, the subsoiler comprises an upper junction plate and a lower junction plate both fixed on a main beam. The upper junction plate is connected with a front end of a self-induced vibration device in a hinged mode, and the self-induced vibration device is connected with an upper end of the subsoiler in a hinged mode. The upside of the subsoiler is also connected with the lower junction plate through a junction adjusting device in a hinged mode. The subsoiler comprises a shovel shaft and a tine point. The part, buried in the ground, of the shovel shaft, and a horizontal plane form a 40-50 degree front slip cutting angle. The subsoiler has the advantages of simple structure, low tillage resistance, flexiblity and adjustability, good tillage adaptability, and long service life.

Description

technical field [0001] The invention relates to agricultural machinery components, in particular to a subsoiling shovel for self-excited vibration and resistance reduction. Background technique [0002] The traditional farming method forms a hard plow layer at the bottom of the soil cultivation layer. The existence of the plow layer seriously hinders the growth of crop roots and water infiltration, and the phenomenon of soil erosion is serious. The use of subsoiling machines for tillage can effectively break the bottom of the plow, improve the structure of the plow layer, and achieve the purpose of water storage, moisture conservation and fertilizer conservation. The traditional subsoiling shovel is generally designed to be rigidly connected to the frame beam. In this way, the subsoiling shovel is fixed relative to the frame, and the working resistance is relatively large. [0003] Vibration drag reduction is an effective method among various drag reduction measures, mainly...

Problems solved by technology

However, the existing self-excited vibration methods usually have the following problems: 1) The tillage resistance needs to be further reduced: under the premise of adopting the self-excited vibration method, the entry angle of the subsoiling shovel still uses the parameters of the forced vibration in the past, which will cause the working parts to vibrate The soil is squeezed, broken and lifted, which leads to high soil cultivation resistance of the machine tools, and due to the lifting effect on the soil, large soil clods and large gaps will be formed on the surface after operation, which will easily cause soil erosion and affect subsequent planting quality

2) Poor adaptability: The conditions of the cultivated land and the requirements for the depth of cultivation are different. It is necessary to adjust the front and rear positions, height, and even angle of the subsoiler according to the actual situation to adjust the depth and width of the subsoiler. However, the current self-excited vibration There are limited means of adjustment in this mode, which affects the working efficiency and service life of the subsoiling shovel

3) The structure of the self-excited device is relatively complex, usually equipped with a spring structure, which is exposed to the external environment for a long time. When farming, dirt, stones and other sundries are easy to splash into it, affecting the normal operation of the self-excited device
