Description

Technical Field

[0001] This application relates to the technical field of agricultural machinery, and in particular to a novel stubble pruning machine. Background Technology

[0002] Currently, notched rakes are commonly used for straw cutting in the market. Due to the working angle, notched rakes inevitably have the problem of straw falling into the gaps and not being cut. To solve this problem, the new stubble shredder uses a blade installation direction perpendicular to the forward direction of the power-driven walking equipment, and prevents gaps from forming between the blades by staggering the front and rear rows of blades. At the same time, towed equipment may not be able to completely cut straw due to insufficient weight. Therefore, it is necessary to design a stubble shredder that can be easily filled with water or sand for counterweight. Utility Model Content

[0003] In order to effectively solve the problems of low efficiency of stubble shredders, gaps between stubble shredder blades, and insufficient weight that prevents complete cutting of straw, this application provides a new type of stubble shredder.

The blade assembly is installed on both sides of the power walking device 1 to expand the simultaneous working range.

[0045] During operation, the first drive mechanism 5 drives the swing arm assembly 23, mounting frame assembly 24, first blade assembly 3, and second blade assembly 4 to rotate around the first connecting shaft 2315. The swing arm assembly 23, mounting frame assembly 24, first blade assembly 3, and second blade assembly 4 can rotate around the fourth connecting shaft 2413. These two rotational configurations allow the stubble cutter to better conform to the ground, improving straw cutting efficiency and preventing excessive impact on the first blade assembly 3 and second blade assembly 4 due to uneven terrain.
