Inclined shaft plow blade arm assembly

Abstract

The invention discloses an inclined shaft plow blade arm assembly, which comprises a harrow blade, a plow blade arm and a hub unit. the hub unit is arranged at the central hole of the notch rake bladeand is in threaded connection with the notch rake blade; one end of the plow blade arm is fixed on the machine square pipe, and the other end of the plow blade arm is fixedly connected with the hub unit through an inner hole; the hub unit comprises an inclined shaft, one end of the inclined shaft, which is connected with the plow blade arm, is an inclined cylinder body with taper, a cross throughhole is formed in the inclined cylinder body, the plow blade arm is selectively connected with any group of through holes in the cross through hole of the inclined cylinder body through an inner hole, thereby realizing the fixation of the rake blade and the selection and adjustment of the tillage angle. According to the inclined shaft plow blade arm assembly, through the structural design of theinclined shaft in the hub unit and the connection between the plow blade arm and the inclined shaft, the adjustment of the fixed scheduling of the harrow blade is realized, so that the adjustment of the working height and the tillage depth of the harrow blade is realized, different operation requirements are met under different conditions, the multi-tillage of one machine is realized, and the flexibility is strong.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an inclined-axis coulter arm assembly. Background technique [0002] The coulter arm assembly is one of the important parts of agricultural machinery, especially the core part of the combined land preparation machine. At present, in the existing coulter arm assembly, after the cutter head and its fixing are fixed, the angle of the cutter head cannot be adjusted, and it can only be used for cultivation at a specific depth, which is unitary. [0003] In addition, in order to improve farming efficiency, most agricultural land preparation machines use string harrows, that is, several or more than a dozen harrow blades are connected between a square tube of the machine, and the coulter arm on the harrow blade and the square tube of the machine are connected by a The screws and nuts are directly fixed, so that in the process of soil preparation, when farming on land with differen...
