Drag type disc harrow

Abstract

The invention discloses a drag type disc harrow which comprises a frame body. A first rotating connecting piece is arranged on the left side of the upper surface of the frame body, a mounting plate isarranged at the upper end of the first rotating connecting piece, and both ends of the mounting plate are provided with mounting grooves, supporting plates are arranged in the mounting grooves and fixed to the mounting plate through adjusting pins, the lower ends of the supporting plates are provided with first bearing blocks, inner rings of the two first bearing blocks are in sleeving connectionwith first rotating shafts, first disc harrow pieces are evenly distributed on the outer surfaces of the first rotating shafts, the left end of the upper surface of the frame body is provided with afirst fixed plate, the two ends of the right side surface of the first fixed plate are provided with first electric telescopic rods, the first electric telescopic rods are connected with the mountingplate through first movable rods, and the right side of the upper surface of the frame body is provided with a second rotating connecting piece. The drag type disc harrow is convenient to use, the angle of the disc harrow pieces is adjusted conveniently without manual adjustment, the depth of the disc harrow pieces into the soil can be adjusted, and the work efficiency is high.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a drag-type disc harrow. Background technique [0002] The disc harrow is a traditional tillage tool in agricultural production, and it used to be one of the necessary farm tools for farmers. It is also one of the Chinese martial arts equipment, which evolved from farm tools. Iron-toothed rakes, with sharp teeth like nails, are highly aggressive and also function as weapons. Disc harrow is based on the principle of harrowing, with groups of concave discs as working parts. The plane of the cutting edge of the harrow is perpendicular to the ground and has an adjustable deflection angle with the direction of the unit. During operation, the rake rolls forward under the action of tractor traction and soil reaction force, the cutting edge of the rake cuts into the soil, cuts off the grass roots and crop residues, and makes the soil rise along the concave surface of the...

AI Technical Summary

Problems solved by technology

The existing drag-type disc harrow has a simple structure, and the angle adjustment of the disc harrow needs to be manually adjusted, which is cumbersome and affects work efficiency, and the depth of the disc harrow is inconvenient to adjust
