Corn harvester equipped with corn straw cutting, smashing, recovering, concentrated placing and strip laying device

Abstract

The invention discloses a corn harvester equipped with a corn straw cutting, smashing, recovering, concentrated placing and strip laying device, and belongs to agricultural machinery. A hob type straw cutting cutter shaft assembly, a straw bidirectional conveying auger shaft assembly and a straw collecting baffle are sequentially arranged below the rear side of a horizontal stem pulling and ear picking roller harvesting table assembly from front to back in parallel. Straw throwing rake teeth are arranged in the middle of the straw bidirectional conveying auger shaft assembly and located at the discharge port of the middle of the straw collecting baffle. A straw smashing device with a smashed straw throwing cylinder assembly is fixedly arranged on the corn harvester. The front end and the rear end of a straw conveying assembly are connected with the discharge port of the straw collecting baffle and the feed port of the straw smashing device. A straw strip laying and unloading plate is hinged to or inserted in the lower portion of a shell of the straw conveying assembly. By means of the device, smashing, recovering or strip laying can be conducted on corn straw in the field, and the device is novel and reasonable in structure, diversified in work function, good in work quality and high in efficiency.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a corn harvester. Background technique [0002] Existing horizontal corn harvester with stem-drawing and ear-picking rollers, including backpack-type corn harvester and self-propelled corn harvester, after completing the operation of harvesting ears of corn, its stalks are scattered in the field. When carrying out autumn land preparation, the straw needs to be cleared out from the field first. The current cleaning method one is to manually remove with manpower, and the other is to pick up and pack machines and tools for recycling. Manual recycling is labor-intensive, low-efficiency, high-cost, and lack of labor are prominent problems. Manual recycling is difficult to achieve, resulting in environmental pollution and loss of agricultural production waste after burning straw in the field. . The baler with telescopic spring-tooth type picking structure can only have a good picking e...

Problems solved by technology

[0005] The invention creates a hob-type straw cutting knife shaft assembly, a straw two-way conveying auger shaft assembly, a straw collecting shield, a straw conveying assembly, a straw crushing device, and a crushed straw thrower by adding a ground hob-type straw cutting knife shaft assembly to the traditional corn harvesting machine. The structure of the cylinder feeding assembly and the straw laying and unloading plate realizes the direct crushing and recycling of corn stalks without falling to the ground after harvesting on the traditional corn harvester, ensuring the quality of the crushed corn stalks as feed raw materials, greatly improving the quality of corn stalks. The soil content is reduced; at the same time, the corn stalks can be collected and placed in strips, which provides support for the operation of the picking and baling machine. It has a novel and reasonable overall structure, multiple operating functions, good operating quality, high operating efficiency, and reliable use. It solves the problem of difficult cleaning of corn stalks from the field and environmental pollution caused by straw incineration. The mutual support and cooperation between the various components and assemblies has produced good technical results.
