Field self-rescue device of rice harvester

Abstract

The invention provides a field self-rescue device of a rice harvester, which belongs to the field of agricultural equipment and comprises a harvester body, a harvester chassis arranged at the bottom of the harvester body, harvester tracks arranged on two sides of the harvester chassis, supporting oil cylinders symmetrically hinged to the bottom of the harvester chassis, and supporting plates hinged to the lower portions of the supporting oil cylinders. Telescopic oil cylinders are arranged on the two sides of the harvester body. And the tail end of the connecting rod is welded with the anchor rod. When the harvester is trapped, the connecting rod and the anchor rod are controlled to be fixed to the ground in front, tension is applied to the harvester, and the harvester is released. When the harvester encounters mechanical faults during operation, especially chassis faults, and needs to be handled, the harvester body can be supported by the supporting plate, so that personnel can conveniently enter the harvester for maintenance. When operation needs to be carried out on different sites, the adjacent operation belts are not flat, and advancing is difficult, at the moment, the connecting rods only need to stretch out, and the sites are tidied.

Description

Technical Field

[0001] The invention relates to the field of agricultural machinery and equipment, and in particular to a field self-rescue device for a rice harvester. Background Art

[0002] When the harvester enters the rice field to work, the harvester is prone to getting stuck due to the soft and slippery ground in the field; the working environment is relatively harsh, making the harvester prone to failure and troublesome to repair. If the chassis fails, it can only be lifted away by a crane for processing; when working in adjacent fields, if the transfer road is not smooth, it can only ask for help from an excavator or take a long detour. These problems seriously affect the progress of the machine operation. This self-rescue device is designed by imitating the excavator arm. When the harvester is stuck, the big arm is controlled to fix the ground in front, giving the harvester a pulling force to get the harvester out of trouble. When the harvester encounters a mechanical failure during operation, especially when the chassis failure needs to be handled, the big arm can be used to prop up the harvester body to facilitate personnel to enter for maintenance. When it is necessary to work in different fields, the adjacent working belts will be uneven, resulting in difficulty in moving. At this time, you only need to extend the big arm and tidy up the site. Summary of the invention

[0003] The purpose of this patent is to solve the problems mentioned in the above background technology, and to provide a field self-rescue device for a rice harvester. When the harvester is stuck, the self-rescue device controls the connecting rod and the anchor rod to fix the ground in front, giving the harvester a pulling force to get the harvester out of trouble. When the harvester encounters a mechanical failure during operation, especially when the chassis failure needs to be handled, the support plate can be used to prop up the harvester body to facilitate personnel to enter for maintenance. When it is necessary to work in different sites, adjacent working belts will be uneven, resulting in difficulties in moving. At this time, you only need to extend the connecting rod and tidy up the site.

[0004] The technical solution of the present invention provides: a field self-rescue device for a rice harvester, comprising a harvester body, a harvester chassis arranged at the bottom of the harvester body, harvester tracks on both sides of the harvester chassis, supporting cylinders symmetrically hinged at the bottom of the harvester chassis, and supporting plates hinged below the supporting cylinders; telescopic cylinders are arranged on both sides of the harvester body; the telescopic cylinders are hinged with connecting rods, and the ends of the connecting rods are welded to anchor rods.

[0005] Preferably, the end of the anchor rod is a conical structure or a cross structure.

[0006] Preferably, the supporting cylinder and the telescopic cylinder are controlled by a controller.

[0007] Preferably, the support plate is a flat plate.

[0008] Principle: The field self-rescue device of the rice harvester uses a support plate and a support cylinder, one end of which is hinged to the support plate and the other end is connected to the harvester chassis; the telescopic cylinder is arranged on both sides of the harvester body; the connecting rod is hinged to the telescopic cylinder; and the anchor rod is welded to the connecting rod.

[0009] When the harvester sinks into the mud, the support plate is lowered and the harvester body is lifted to a suitable position by controlling the extension and retraction of the supporting cylinder. The connecting rod of the telescopic cylinder is then extended to a specified position and the supporting cylinder is slowly retracted. The anchor rod is inserted into the mud by its own gravity and anchored by the anchoring structure. Finally, the telescopic cylinder is retracted and the pulling force of the telescopic cylinder is used to pull the harvester out of the pit. The process is simple and quick, does not affect the harvesting efficiency, can achieve a good self-rescue effect, and does not require an additional rescue vehicle.

[0010] Beneficial effects of the present invention: 1. If the device gets into trouble or encounters mechanical failure during operation, it can free itself without external help and is easy to maintain.

[0011] 2. This device can save time, manpower and material resources.

[0012] 3. When you need to work in different sites, such as hilly areas, you may encounter uneven adjacent working areas, which will make it difficult to move. At this time, you only need to extend the boom and tidy up the site.

[0013] 4. The bucket at the front end of the device can facilitate the transportation of rice and straw. BRIEF DESCRIPTION OF THE DRAWINGS
