Description

Technical Field

[0001] This utility model belongs to the technical field of material conveying equipment, and specifically relates to a bottom cleaning system for a material elevator. Background Technology

[0002] In the field of material hopper conveying technology, hopper structures are typically used to hold materials, which are then conveyed via a conveyor chain. The current technical problem is that during the material conveying process, because the chain and hopper are connected, during operation, especially at the bottom turning point of the chain inside the conveyor, the hopper and chain experience pulling and collisions, which can cause the hoppers to stack and the material to spill to varying degrees. After a long period of material accumulation, it will affect the normal operation of the conveying hoppers at the bottom of the conveyor.

[0003] To address the shortcomings of existing technologies, the current solution for those skilled in the art is to disassemble the bottom outer shell of the conveyor at regular intervals and clean the interior manually. However, this method is inefficient and often results in the tilting of the internal hoppers or affects their normal operation due to negligence in cleaning, ultimately causing the entire equipment to malfunction.

[0004] As those skilled in the art, there is an urgent need to design a bottom cleaning system for material elevators through technological improvements, which can achieve bottom cleaning of material elevators through an automated system to avoid equipment failure. Summary of the Invention

[0005] To overcome the shortcomings of existing technology, this utility model provides a bottom cleaning system for a material elevator. By setting a conveying device at the bottom of the elevator, the material can be conveyed to the outside or the falling material can be directly guided back into the material elevator through the lifting device.

[0006] To achieve the above technical objectives, the present invention adopts the following solution: A bottom cleaning system for a material hoist includes a hoist body with a steering drive shaft inside. The steering drive shaft drives the conveyor buckets to change direction. A conveyor belt is positioned below the conveyor buckets. An external discharge port is located outside the hoist body, coordinating with the conveyor belt, to convey materials to the outside. A discharge area is located below the external discharge port, allowing personnel to directly move vehicles to the discharge area for material discharge.

[0007] The bottom of the elevator body is provided with an adjustable support seat, which provides horizontal support for the conveyor belt. The adjustable support seat is provided with an adjusting screw and an adjusting nut. The lateral movement of the adjustable support seat is adjusted by controlling the adjusting nut.

[0008] An external discharge drive motor is installed in the discharge area to achieve the turning of the conveyor belt end.

[0009] The elevator body has a turning section at its end, which rises to the top of the conveying hopper. A feeding port is provided at the end of the turning section to supply material again. The turning section is a C-shaped arc, and a turning support shaft is provided at the end of the C-shaped arc. A scraper is provided on the conveyor belt. The turning support shaft can constrain the scraper on the conveyor belt to be in close contact with the inner wall of the C-shaped arc. The scraper scrapes the material to the feeding port and releases the material by being in close contact with the inner wall of the C-shaped arc.

[0010] The hoist body is equipped with several observation ports, which allow for the inspection and maintenance of the conveying hopper area and the conveyor belt area.

[0011] An end-drive device is provided on the C-shaped arc segment. The end-drive device is located near the feed port to ensure that the conveyor belt has a stable operating state when releasing materials.

[0012] The steering drive shaft includes at least one adjustable drive shaft, and the tension of the conveying hopper between the two is achieved by adjusting the adjustable drive shaft.

[0013] The beneficial effects of this utility model are as follows: A steering drive shaft is provided within the elevator body to drive the conveying bucket to turn. A conveyor belt is installed below the conveying bucket. An external discharge port is provided outside the elevator body in conjunction with the conveyor belt to transport materials to the outside, enabling automated material removal. Furthermore, a steering section is provided at the end of the elevator body. This steering section rises to the top of the conveying bucket, and a feeding port is provided at the end of the steering section to resupply materials, achieving lossless material recovery.

[0014] This invention solves the problem of the inability to clean the conveyed materials in the prior art, and can realize external cleaning and recycling. It overcomes the shortcomings of the prior art and is an ideal bottom cleaning system for material elevators. Attached Figure Description
