A grass cutting tail plate adjustment device

Abstract

The utility model provides a chopper grass discharge tail plate adjustment device, including a chopper body, and side plates are arranged on both sides of the chopper body. During the driving process of the utility model, the grass discharge tail plate may hit foreign objects when the harvester turns or reverses, and may also hit the ridge when going to the field to harvest. When this happens, the torsion spring at the connection of the grass discharge tail plate will deform first, thereby avoiding damage to the grass discharge tail plate. During the harvesting operation, the grass discharge tail plate has a small opening angle before the grain is fed. As the feeding amount continues to increase, the grass discharge amount will also increase accordingly, and then the force on the grass discharge tail plate will gradually increase. The force on the grass discharge tail plate will continue to increase, which will cause the angle of the grass discharge tail plate to continue to expand, so that the crushed straw can be sprayed more evenly in the field. The opening of the grass discharge tail plate can automatically adjust the opening according to the feeding amount of different working fields, so that the crushed straw can be thrown more evenly.

Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a grass-discharging tail plate adjusting device of a chopper. Background Art

[0002] As a country with a large population, my country has a huge demand for agricultural crops, so harvesters are needed to save a lot of manpower and material resources. With the further implementation of my country's environmental protection policies, many places have successively issued regulations prohibiting the burning of straw on the spot, so the chopper has become an indispensable part of the harvester. However, after installing the chopper, the overall length of the machine will be lengthened, which is not convenient for operation. In addition, some emergencies may occur, which will make the chopper's grass discharge device easily collide, thereby damaging the grass discharge device. The choppers on the market are now rigidly combined, but the feed volume of the work site may vary greatly during the harvesting operation, so the discharge volume will also be completely different, and the grass discharge device cannot handle it better.

[0003] The existing grass discharge tail plate of the chopper has the following defects:

[0004] 1. The tailgate of the vehicle is easily damaged by impact during driving;

[0005] 2. The angle of the grass discharge tailgate cannot be automatically adjusted according to the amount of grass discharged. Utility Model Content

[0006] The utility model aims to provide a grass-discharging tail plate adjusting device for a chopper to overcome the above-mentioned problems or at least partially solve the above-mentioned problems.

[0007] In order to achieve the above-mentioned purpose, the technical solution of the utility model is specifically implemented as follows:

[0008] The utility model provides a chopper grass discharge tail plate adjustment device, comprising a chopper body, side plates are arranged on both sides of the chopper body, a grass discharge tail plate is installed at the grass discharge port at the bottom of one side of the chopper body, and both ends of the grass discharge tail plate are installed on the side plates through adjustment components;

[0009] The adjusting assembly includes a connecting shaft, a torsion spring, a first limiting tube, a second limiting tube, a connecting seat and a connecting plate. A connecting shaft is welded on the top of the grass-removing tail plate, and both ends of the connecting shaft extend to both sides of the grass-removing tail plate respectively, and the extending parts of both ends of the connecting shaft are sleeved with torsion springs. A first limiting tube is welded on the side of the grass-removing tail plate, one end of the torsion spring is sleeved in the first limiting tube, a second limiting tube is welded on the side plate, and the other end of the torsion spring is sleeved in the second limiting tube. A connecting seat is also welded on the side plate and next to the second limiting tube, and a connecting plate is installed on the connecting seat. The connecting plate is sleeved on the end of the connecting shaft and fastened with bolts.

[0010] As a further solution of the utility model, the connecting plate is installed on the connecting seat by bolts and nuts.

[0011] As a further solution of the utility model, a pulley is installed on one of the side plates, and an upper cover is installed on the top of the chopper body.

[0012] The utility model provides a grass cutter tail plate adjustment device, which has the following beneficial effects:

[0013] 1. The utility model cleverly utilizes the structural characteristic of the torsion spring. By improving the structure of the grass removal device, the torsion spring can be added to the connection of the grass removal device, so that the grass removal tail plate can independently adjust the opening angle according to different force conditions. The structure is simple, the cost is extremely low, and it is easy to disassemble.

[0014] 2. During driving, the tailgate may hit foreign objects when the harvester turns or reverses, or it may hit the ridge when harvesting in the field. When this happens, the torsion spring at the connection of the tailgate will deform first, thereby avoiding damage to the tailgate.

[0015] 3. During harvesting operations, the opening angle of the grass discharge tail plate is small before the grain is fed. As the feeding amount continues to increase, the grass discharge amount will also increase accordingly, and the force on the grass discharge tail plate will gradually increase. The increasing force on the grass discharge tail plate will cause the angle of the grass discharge tail plate to continue to expand, so that the crushed straw can be sprayed more evenly in the field. The opening of the grass discharge tail plate can automatically adjust the opening according to the feeding amount of different operating fields, so that the crushed straw can be thrown more evenly.
