Chain type harvest header for composite feed crop straw

Abstract

The invention relates to a chain type harvest header for composite feed crop straw. The harvest header comprises a rack and a chain type cutter mounted on the rack, wherein the chain type cutter comprises a fixed knife mechanism fixedly connected with the rack, a plurality of moving blades fixedly connected to the outer side face of a annular chain, and a driving device for driving the annular chain to rotate, and a cutting surface is formed between the moving blades and fixed blades. According to the chain type harvest header for the composite feed crop straw, the moving blades are driven bythe annular chain to move at a high speed, cutting of crop stalks is completed through mutual cooperation of the moving and fixed blades, and the moving blades are prevented from bouncing up and downthrough a knife pressing rod, so that the gap between moving and fixed knives is ensured, cut stubbles are flat and smooth, re-germination of composite feed crops such as imperatoria and protein mulberry is facilitated, and cutting, harvesting and horizontal laying of the composite feed stalks can be realized by arranging a stalk horizontal conveying device.

Description

technical field [0001] The invention belongs to the field of agricultural machinery and equipment, and in particular relates to a chain-type forage crop stalk harvesting platform. Background technique [0002] Forage is the foundation and premise of the development of animal husbandry, and it is rich in nutrition. However, the level of mechanized harvesting of forage in my country is still relatively backward compared with that of European and American countries. To a certain extent, the level of mechanized harvesting of forage restricts the development of animal husbandry in China. [0003] Currently, reciprocating cutters and rotary cutters are widely used. When cutting rough and hard forage straw, the cutting speed of the reciprocating cutter is low, there is a phenomenon of continuous cutting and it is easy to be blocked, while the rotary cutter such as the disc cutter requires a higher speed, which poses a safety hazard And the cutter life is short. The higher rotatio...

AI Technical Summary

Problems solved by technology

[0006] When harvesting, this solution drives the ring chain to rotate through the driving device, and then drives the moving blade and the fixed blade to move relative to each other, so as to realize the cutting of the straw, which not only solves the problem of low cutting speed and easy blockage of the reciprocating cutter, but also solves the The problem of high speed and short blade life of the disc cutter, the cutting stubble is smooth, and a toothed blade can be set at the front end of the fixed knife to make cutting more labor-saving
