A Disc Cutting Grass Cutting Stubble Crush Soil Fertilizer Applicator

Abstract

The invention provides a disk grass cutting, stubble cleaning and hacking fertilizer applicator. A urea fertilizer tank and a compound fertilizer tank are arranged on the front portion of a rack; multiple first operating mechanisms, multiple front grid units, multiple second operating mechanisms and multiple rear grid units are sequentially arranged below the rack in the width direction from front to back; each first operating mechanism and each second operating mechanism are each composed of a pull rod, a disk harrow piece and a connecting base, wherein the pull rod is composed of a beam and a vertical beam connected with the rear end of the beam, the front end of the beam is connected with the rack through the connecting base, and the disk harrow piece is rotationally assembled at the lower end of the vertical beam in the length direction of the rack. The upper end of a rotating support on the rear portion on the rack is hinged to the inflection point of an L-shaped lifting arm, a land wheel is arranged at the lower end of the L-shaped lifting arm, a piston rod of a hydraulic cylinder is hinged to the upper end of the L-shaped lifting arm, and a cylinder base of the hydraulic cylinder is hinged to a fixed frame. The fertilizer applicator integrates fertilizer applying, grass cutting, stubble cleaning and hacking functions, the operation working procedures can be effectively reduced, the number of times of land rolling through a machine can be reduced, operation efficiency can be improved, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a disc-cut grass-cutting, stubble-cutting and soil-cracking fertilizer applicator. Background technique [0002] Before the sowing operation, it is necessary to carry out the fertilizer spreading operation, and then carry out the grass cutting, stubble removal, and soil crushing operations. Since the functions of the existing agricultural machinery and tools are relatively single, to complete the above operation process, it often requires a variety of machinery and tools to carry out joint operations. Not only are there many operating procedures and low operating efficiency, but also the number of times the tractor presses the ground increases, which is not conducive to the germination and growth of seeds. At the same time, it also increases energy consumption and increases production costs. Contents of the invention [0003] Aiming at the problems existing in th...

[0002] Before the sowing operation, it is necessary to carry out the fertilizer spreading operation, and then carry out the grass cutting, stubble removal, and soil crushing operations. Since the functions of the existing agricultural machinery and tools are relatively single, to complete the above operation process, it often requires a variety of machinery and tools to carry out joint operations. Not only are there many operating procedures and low operating efficiency, but also the number of times the tractor presses the ground increases, which is not conducive to the germination and growth of seeds. At the same time, it also increases energy consumption and increases production costs.
