Elastic vibratory deep scarification unit

Abstract

The invention discloses an elastic vibratory deep scarification unit, which belongs to agricultural machinery. A shovel seat is arranged on an assembly rack through a pin shaft; a deep scarification and soil crushing assembly is assembled on the shovel seat; a spring pressure plate is fixedly arranged on the rear part of the upper end of the deep scarification and soil crushing assembly; a spring positioning plate is fixedly arranged on the upper part of the front end of the assembly rack; the front part of a spring shaft is inserted in the spring positioning plate in an axial movable manner; the rear end part of the spring shaft is hinged with the spring pressure plate; a pressure spring is sleeved on the spring shaft; and front and rear end faces of the pressure spring are contacted and matched with the spring positioning plate and the spring pressure plate respectively. The elastic vibratory deep scarification unit has the advantages of simple structure, low manufacturing cost, stable work, small traction resistance, high reliability, good deep scarification and soil crushing effects and wide application range.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to an elastic vibrating subsoiling unit assembled on a stubble removing rotary tillage and ridge raising combined land preparation machine tool. Background technique [0002] The existing subsoiling components mainly have two structures. One is the traditional fixed subsoiling component structure. This type of component not only has no overload protection device, but also has a high damage rate during use, poor safety, and the adjustment operation is also very complicated and difficult; two. In recent years, the combined land preparation machine imported from abroad has adopted overload protection subsoiling parts, which has enhanced the adaptability to the soil and improved safety, but there are still large operating resistance, high traction power consumption, and poor subsoiling and crushing effect. The ideal technical problem urgently needs to be solved. Contents of the invention...
