Subsoiler

Abstract

The invention discloses a subsoiler, comprising a frame which is provided with a connecting plate arranged above the right front end, an upper cantilever and a lower cantilever which are arranged at the front end of the frame, a pair of depth wheels which are connected at two sides of the frame by a depth axle, a depth wheel supporting frame and a depth wheel supporting frame connecting screw, a subsoiler handle which is provided with a subsoiler tine point and connected with a rear arm of the frame by a subsoiler fixed plate and a subsoiler fastening screw. The subsoiler is characterized in that a disc coulter which is connected with the connecting plate by a coulter connecting rod fastening screw, a coulter connecting rod, a disc coulter shaft and a disc coulter bracket is arranged at the front upper part above the subsoiler tip; the center of the disc plow and the center of the subsoiler handle are on one line; the subsoiler tip is an arrow-shape and the subsoiler handle is a bow-shape. The subsoiler effectively solves the phenomena of weed blocking and large clod during the working process, reduces the width of the cracking surface of the ground surface, effectively restricts the ineffective evaporation of the water and reduces the working resistance.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and relates to a subsoiler. Background technique [0002] The subsoiler is an operating machine widely used for deep loosening of cultivated land soil to increase the precipitation infiltration rate and increase the soil water storage capacity. The structure of the subsoiler produced in my country mainly includes a frame, a subsoiler handle, a shovel point, an adjustment wheel, an upper suspension pin, and a lower suspension pin at present, but the subsoiler of this structure has the following problems, 1) in During the operation, it is easy to be blocked by debris in front of the shovel, which affects the quality of the operation and increases the resistance of the operation: 2) Due to the dryness of the ground and the relatively thick deep loose soil layer, large soil clods are prone to occur, resulting in uneven ground surface and affecting subsequent operations. At the same time, it is eas...
