Problems solved by technology

[0004] 1) The cost of rubber track is relatively high;
[0005] 2) The life of the rubber track is short, once it is damaged, it must be replaced as a whole;
[0006] 3) Bending plate chain type, the force direction of the bending plate structure is perpendicular to the chain plate, the impact resistance is poor, and it is easy to break when used;
[0007] 4) Bending plate chain type, if dirt and dust enter the chain links during use, the chain will be worn and the service life will be reduced;
[0008] 5) Neither device can be installed with a shaft roller with a larger diameter, and the thin shaft roller is not wear-resistant, and it is easy to bend and damage when receiving impact;
[0009] 6) The shaft and roller of the two devices are completely connected by a single fastener, which has poor stability and is easy to fall off during use;
[0010] 7) The pin rollers of the two devices are in contact with the soil and the fasteners of the transmission device, which are easily damaged

Abstract

The invention discloses a chain for an agricultural harvester and a chain accessory for the agricultural harvester. The chain for the agricultural harvester comprises multiple shaft rollers which are arranged longitudinally and multiple chain bodies which are transversely arranged on the shaft rollers side by side, wherein each chain body comprises multiple chain link units, and each chain link unit comprises a first chain link and a U-shaped second chain link. According to the chain for the agricultural harvester, the second chain links of the U-shaped structure are adopted, the stress direction is parallel to fixing plates on the second chain links when the chain is used, impact resistance is achieved, and the service life is prolonged.

Description

technical field [0001] The invention relates to a chain for an agricultural harvester and its chain accessories. Background technique [0002] In the vast rural areas of our country, root crop harvesters have begun to be widely used. At present, there are two main types of conveying devices on the harvester on the market. One is a rubber crawler 1, and the shaft roller 2 is fixed on it by a fastener 3. For its structure, see Figure 1-2 ; The second is the curved plate chain, the shaft roller 5 is penetrated into the annex 6 with holes, and then the annex 6 is fixed on the curved plate 7 by the fastener 4, its structure is shown in Figure 3-4 . [0003] These two teleporters have some notable disadvantages: [0004] 1) The cost of rubber track is relatively high; [0005] 2) The life of the rubber track is short, once it is damaged, it must be replaced as a whole; [0006] 3) Bending plate chain type, the force direction of the bending plate structure is perpendicular ...
