Front harrow set for disc harrow and using method of front harrow set

Abstract

The invention relates to a front harrow set for a disc harrow and a using method of the front harrow set and belongs to the technical field of disc harrows. The front harrow set comprises a cross beamand a plurality of harrow sheets connected with the cross beam; the harrow sheets are divided into a left group and a right group which are identical in number and are arrayed below the cross beam; the harrow sheets in the middle of each group are separated by partition pipes, the harrow sheets close to the two ends in the harrow set and the middle harrow sheets are separated by splicing long semi-partition pipes with short semi-partition pipes, and a bearing bracket is mounted between each long semi-partition pipe and the corresponding short semi-partition pipe and fixedly connected with thecross beam; the lower end of each bearing bracket is fixedly connected with a bearing base, a square hole bearing is mounted in each bearing base, and square holes with the same size are formed in the harrow sheets, the partition pipes, the long semi-partition pipes and the short semi-partition pipes and communicated with the square hole bearings; a square shaft is fixed in each square hole. Theharrow set has the advantages of stable integral structure, uniform harrow sheet spacing and good tillage effect.

Description

technical field [0001] The invention belongs to the technical field of disc harrows, and more specifically relates to a front harrow group for disc harrows and a usage method thereof. 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...

Problems solved by technology

[0005] The purpose of the present invention is to solve the defects of unstable connection of harrow groups used in disc harrows, uneven spacing of harrow blades, and poor cultivation effect in the prior art, and provide a front harrow group for disc harrows and its use method, which have the advantages of The overall structure of the harrow group is stable, the spacing between the harrow blades is even, and the plowing effect is good.
