Independent plough coulter arm assembly

Abstract

The invention discloses an independent plough coulter arm assembly, which comprises a notch harrow blade, a plough coulter arm, a hub unit, V-shaped plates and a rubber suspension; the hub unit is arranged at the central hole of the notch harrow blade; one end of the plough coulter arm is fixedly connected with a shaft of the hub unit, and the other end of the plow coulter arm is provided with a V-shaped opening; the two V-shaped plates are connected into a whole in the opposite direction of the V-shaped opening, one of the V-shaped plates is embedded and welded on the V-shaped opening of theplough coulter arm, a machine square pipe penetrates through the space between the two V-shaped plates, and the rubber is suspended is filled in the gap between the machine square pipe and the two V-shaped plates. According to the structure design, each coulter head works independently, and the depth of cultivated land is adjusted through the buffering action when the coulter head cultivates on the ground with different heights, so that the maintenance in the use process is achieved, and the time is effectively saved; the independent plough coulter arm has higher strength and impact resistance, can provide a perfect working state even under the worst environment, and improves the tillage effect and efficiency.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an independent 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 order to improve farming efficiency, the vast majority of 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 with each other. The screws and nuts are directly fixed, so that in the process of soil preparation, when farming on land with different heights, there will be different depths of cultivation, which will affect the lower effect. [0003] In addition, the combined land preparation machine has been working in a harsh environment full of dust and...

Problems solved by technology

At present, in order to improve farming efficiency, the vast majority of 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 with each other. Screws and nuts are directly fixed, so that in the process of soil preparation, when farming on different heights of land, there will be different plowing depths, which will affect the lower effect

[0003] In addition, the combined land preparation machine has been working in a harsh environment full of dust and gravel for a long time, and bears strong impacts. Therefore, its coulter arm components need regular maintenance, which consumes a lot of man-hours. For time-critical agricultural farming very unfavorable
