Rotary cultivator tool apron and manufacturing method thereof

Abstract

The invention discloses a rotary tiller knife seat, which comprises a knife seat body, a reinforcing eaves and a reinforcing rib; the knife seat body is a hollow steel pipe with rounded corners, the upper end of the knife seat body is a plane, and the lower end The arc surface extending on the left and right sides; the front side wall of the knife seat body is provided with a regular hexagonal through hole, and the rear side wall is correspondingly provided with a circular through hole, and the top of the knife seat body is provided with a reinforcement protruding around. The eaves are respectively provided with reinforcement ribs between the reinforcement eaves and the two narrower side walls of the tool holder body. The knife seat has a simple structure and a reasonable design, significantly increases the hardness and strength of the knife seat, is not easy to crack, and has a significantly prolonged service life. The invention also provides a manufacturing method of the knife seat, which is simple and easy to operate, has high production efficiency and low production cost, and ensures the mechanical properties of the knife seat without heat treatment.

Description

technical field [0001] The invention relates to a rotary tiller blade seat and a manufacturing method thereof, belonging to the technical field of agricultural machinery. Background technique [0002] The rotary tiller is a tillage machine that is matched with a tractor to complete plowing and harrowing operations. The rotary tiller has the characteristics of strong soil breaking ability and flat surface after plowing. At the same time, it can chop the root stubble buried below the surface. Finely crushed, evenly mixed with soil and fertilizer, it meets the requirements of sowing in dry land or planting in paddy field, which is conducive to gaining farming time, improving work efficiency, and can make full use of the power of tractors, so it has been widely used. The working part of the rotary tiller is a rotating blade, which is installed on the knife seat, and the knife seat is welded to the knife shaft, and the blade is driven to rotate by the rotation of the knife shaft....

AI Technical Summary

Problems solved by technology

When this kind of knife holder is in use, due to the resistance when cultivating the land, a large moment will be generated, and the knife holder will be subjected to a large circumferential force. On the other hand, the stress-fragile parts such as the corners of the rectangular flat tube are easily cracked and damaged after being stressed, and the service life is low, which affects the normal operation of the rotary tiller.

The current rotary tiller blade holders are mostly made by casting, and the quality of casting blade holders largely depends on the effect of heat treatment. Once the heat treatment effect is not good, the strength of the blade holder will be significantly reduced, and the uniformity of the blade holder drop, very unstable quality, prone to breakage and damage
