Spring preload adjustable vibration subsoiler

Abstract

The invention belongs to agricultural land cultivating machinery and particularly relates to a vibrating subsoiler with adjustable spring pre-tightening force. The vibrating subsoiler with the adjustable spring pre-tightening force comprises a machine frame (1), depth wheel assemblies (2), self-excited vibration units (4) and a three-point linkage device (8), wherein the three-point linkage device (8) is arranged on the machine frame (1), and the vibrating subsoiler with the adjustable spring pre-tightening force is connected with a tractor through the three-point linkage device (8); the depth wheel assemblies (2) are fixed to the two sides of the machine frame (1) through U-shaped bolts (3); the self-excited vibration units (4) are fixed to the machine frame (1). The vibrating subsoiler with the adjustable spring pre-tightening force can reduce cultivation resistance thereto and power consumption of the tractor, adapt to soil in different regions and enhance universality of application regions.

Description

technical field [0001] The invention belongs to agricultural land machinery, in particular to a vibrating subsoiler with adjustable spring preload. Background technique [0002] The subsoiler can destroy the hard plow bottom layer, deepen the plow layer, make the soil form a structure with both virtual and solid, increase the water permeability and air permeability of the soil, and improve the growth environment of crops. Subsoiling technology can greatly increase the yield of crops and is an important technology for increasing production. [0003] During the working process of the subsoiler, reducing tillage resistance is the first issue that needs to be considered. Reducing tillage resistance can prolong the service life of the subsoiler, reduce the power consumption of the tractor, and achieve the purpose of energy saving and emission reduction. my country has a vast territory, and there are great differences in the physical properties of soil between different regions,...

AI Technical Summary

Problems solved by technology

The non-vibrating subsoiler cannot reduce the tillage resistance and increases the power consumption of the tractor; although the forced vibratory subsoiler can reduce the tillage resistance, it needs the tractor to provide power during the working process, which saves labor and effort during the subsoiling process. , and these machines can only be used in some specific areas, not universal

Most foreign subsoilers are self-excited vibrating subsoilers. The self-excited vibration unit is mainly composed of compression springs. The pre-tightening force of the springs is fixed and cannot be adjusted, and the adaptability to the land is poor.
