Problems solved by technology

[0006] The current rotary cultivating knife is made of a piece of equal thickness steel plate, and the thickness of the back of the knife is consistent with other parts of the blade body. This rotary cultivating knife has a simple structure and is easy to manufacture. The thickness of the cutting edge is equal to the thickness of other parts of the knife body, and the resistance of the rotary tiller is greater when it enters the soil. At this time, it not only increases the power consumption of the rotary tiller, but also tends to cause weeds to entangle the rotary tiller, increasing the impact of the rotary tiller. resistance to knife rotation

Abstract

The invention belongs to the field of fittings of a rotary blade, and particularly discloses a rotary blade. The rotary blade comprises a blade back, a blade edge part and a blade holder part, wherein the blade back and the blade edge part are curved, the blade edge part is positioned at the external curved part of the blade back, and the blade edge part is cuneiform. The rotary blade has the characteristics of being small in buried resistance and capable of cutting weeds.

Description

technical field [0001] The invention relates to the field of rotary tiller accessories, in particular to a rotary tiller. Background technique [0002] A rotary tiller is a tillage machine that is matched with a tractor to complete plowing and harrowing operations. It has been widely used because of its strong soil breaking ability and flat surface after plowing. At the same time, it can chop up the root stubble buried below the surface, which is convenient for the seeder to operate and provides a good seed bed for later sowing. [0003] Rotary tillers can be divided into horizontal axis type (horizontal type), vertical axis type (vertical type) and oblique axis type according to the position of the rotary tiller shaft; according to the connection mode with the tractor, they can be divided into traction type, suspension type and direct connection type ;According to the transmission mode of the cutter shaft, it can be divided into the middle transmission type and the side tr...
