Description

Technical Field

[0001] The invention relates to supporting conveying equipment in the field of bagged grain entering warehouses, and in particular to a bagged grain entering warehouse conveying device. Background Art

[0002] The bulk grain is bagged into bagged grain, which is then transported to the warehouse by a grain truck. Workers then unload the bagged grain and use a conveyor to transport the bagged grain to the warehouse.

[0003] The problem existing in the prior art is that the stacking height of bagged grain on the grain transport vehicle is relatively high. Workers need to transport the bagged grain with a higher height to the conveyor with a lower height, and they need to use corresponding conveying devices. Existing conveying devices of this type, such as "a packaged grain unloading system" disclosed in Chinese patent CN114455343A, are also a conveying device that our company has tried before. The conveying device includes a system support, on which a low-level conveyor and a high-level conveyor with adjustable height are arranged. The system support is provided with a conveyor height adjustment mechanism for driving the high-level conveyor to adjust its height. The packaged grain unloading system also includes a spiral feeding device for conveying the packaged grain at the discharge end of the high-level conveyor to the feed end of the low-level conveyor. The spiral feeding device includes a feeding cylinder and a spiral blade fixed in the feeding cylinder. A plurality of feed ports spaced apart in the up-and-down directions are provided on a cylinder wall on one side of the feeding cylinder facing the high-level conveyor.

[0004] The high-level conveyor and the low-level conveyor share a conveyor belt, and the height adjustment of the high-level conveyor is achieved through a chain. The existing problems with this type of conveying device are: it has both a high-level conveyor and a low-level conveyor, and a spiral unloading device is required, which has a relatively complex structure; the high-level conveyor and the low-level conveyor share a long conveyor belt to transport bagged grain, and the transportation efficiency is not high; in addition, the height adjustment of the high-level conveyor is achieved by lifting and lowering the chain, and its stability is not particularly ideal.
