Subsoiler used together with four-wheel tractor

Abstract

The invention relates to agricultural machinery, in particular to a subsoiler used together with a four-wheel tractor. In the subsoiler used together with the four-wheel tractor, a subsoiling shovel shaft fixing element is welded on the back side of a subsoiler large frame; a leveling roller is in hinged connection with the subsoiler large frame through the upper end of a leveling roller connecting piece; a subsoiling shovel arrow faces a ditching disc and is in welded connection with the lower end of a subsoiling shovel shaft; the ditching disc is fixed on a side plate of the subsoiler large frame through a ditching disc shaft and a bearing seat; and a depth limiting wheel is fixed at the front end of the subsoiler large frame through a depth limiting wheel positioning piece. The subsoiler realizes subsoiling operation of the four-wheel tractor, has a simple structure, is convenient to operate, improves operation efficiency and lowers the requirements on intensities of the subsoiling shovel shaft and parts. In particular, the problem of unavailable cultivating by using the ordinary subsoiler during grassland subsoiling is solved and the aim of performing protective cultivation is fulfilled. The subsoiler used together with the four-wheel tractor is suitable for subsoiling on hard soil or grasslands.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a subsoiler matched with a four-wheel tractor. [0002] Background technique [0003] With the continuous improvement of the degree of agricultural mechanization, various agricultural machinery used in agricultural cultivation, harvesting, ridging, fertilization, etc. have provided convenience for the majority of farmers. However, for the subsoiler used in returning farmland to grassland, because the turf of the grassland is particularly thick and the grass roots are intertwined, ordinary subsoilers cannot plow deeply at all. And the subsoiler that is used at present and four-wheel tractor is used for returning farmland to grassland and ditching earlier, deep plowing land and can level land subsequently, also does not see record. Contents of the invention [0004] The purpose of the present invention is to provide a subsoiler matched with a four-wheel tractor in view of the deficien...

AI Technical Summary

Problems solved by technology

However, the subsoiler used in returning farmland to grassland, because the turf of the grassland is particularly thick and the grass roots are intertwined, the ordinary subsoiler cannot plow deeply at all.

At present, there is no record of the subsoiler used in conjunction with four-wheel tractors for returning farmland to grassland, first digging ditches, then deep plowing the land, and then leveling the land.
