Description

Technical Field

[0001] The utility model belongs to the technical field of grain collecting equipment, in particular to a cleaning device for a grain collecting and loading machine. Background Art

[0002] After harvesting, various granular crops, such as rice and wheat, are mostly dried, bagged, and stored in warehouses. The traditional method is manual bagging, that is, using a shovel or spade to manually put the crops into packaging bags and then put them into the warehouse. This is not only labor-intensive, but also very inefficient in harvesting crops. Therefore, grain harvesters that automatically collect grain have appeared in the market.

[0003] For example, the existing Chinese utility model patent with publication number CN216638239U discloses an anti-aircraft artillery grain collecting and loading machine. By understanding the specification and the drawings, it can be known that the scheme includes a frame, a lateral convergence, and a longitudinal lifting cylinder; a power frame is provided in the middle of the frame; a power frame is provided on the power frame; a scraper-type cleaning brush is provided on the frame, and the scraper-type cleaning brush is driven by a chain, the chain is driven by a shaft, and the shaft is driven by power. The scraper-type cleaning brush sweeps the remaining grain into the side with grain, and finally all the grain is loaded into the carriage. However, the height adjustment of the scraper-type cleaning brush is inconvenient, and when the brush is worn, its cleaning effect is greatly reduced. In addition, since the scraper-type cleaning brush is installed on the frame, the front and back are an integral whole, when the front and back ground on the walking path is twisted or uneven, its cleaning effect is poor.

To adapt to this scheme, a universal joint is provided between the transmission shaft and the chain.

[0028] A pulling mechanism 3 is fixedly connected to the front end of the frame 1 , and a lifting and lowering adjustment mechanism 4 is fixedly connected to the rear end of the frame 1 .

[0029] See also Figure 1 and Figure 3 As shown, the pulling mechanism 3 includes a pulling bolt 301 and a pulling sleeve 302. The circumferential side of the pulling sleeve 302 is fixedly connected to the end of the frame 1. The pulling bolt 301 and the pulling sleeve 302 are rotatably matched.

[0030] See also Figure 1 and Figure 2As shown, the lifting and adjusting mechanism 4 includes a pair of large arms 401 and a pair of small arms 402. The pair of large arms 401 are welded and fixed on both sides of the frame 1. One end of the small arm 402 is hinged to the lower end of the large arm 401, and the other end of the small arm 402 is fixedly installed with a universal wheel 405. The pair of large arms 401 are fixedly connected by a large arm connecting rod 403, and the pair of small arms 402 are fixedly connected by a small arm connecting rod 404.
