Description

Technical Field

[0001] The utility model relates to the technical field of transmission mechanisms, and specifically relates to a sand and gravel transmission mechanism. Background Art

[0002] Slag is mainly an uneven mixture composed of molten slag, stones, metal objects, glass, ceramics, sand, etc. The chemical properties of slag are relatively stable, with good durability and high strength. After processing, different proportions of auxiliary materials such as cement can be added to the slag according to different needs. After high-temperature combustion, a large amount of sand and gravel will be produced from the slag, which has strong stability. In the application of subgrade materials, it can be mixed with stones, lime, etc. and used as the subgrade bedding in highway construction.

[0003] A Chinese patent with the authorization announcement number CN214358330U discloses a sand and gravel transmission mechanism for an automatic sand production line, including a conveyor table, a first mounting plate and a second mounting plate. One side of the second mounting plate is fixedly connected with a motor frame, and a motor assembly is arranged inside the motor frame. One end of the motor assembly is fixedly connected with a rotating rod, one end of the rotating rod is provided with a rotating shaft, and a driving roller is fixedly connected to the surface of the rotating rod. By setting the first rotating shaft, the first rotating roller, the second rotating shaft and the second rotating roller, the conveyor belt body can be bent into a U-shaped shape during the process of transmitting sand and gravel, ensuring that the sand and gravel can be transmitted more stably. In the actual use process, the staff can place the sand and gravel to be transmitted on the conveyor belt body, and then start the motor assembly in the motor frame to drive the driving roller to rotate.

[0004] However, the above technical solution has the following defects: In the above sand and gravel transmission mechanism, the sand and gravel particles are transmitted on the sunken conveyor belt, but the open conveyor belt causes a large amount of dust during the conveying process, and the angle of the conveying mechanism cannot be adjusted. When the conveying angle changes, the sand and gravel will still fall off the conveyor belt, which is not convenient to use. Summary of the Utility Model
