Description

Technical Field

[0001] This utility model belongs to the technical field of sand washing machines, specifically relating to a sand washing machine with a bent screen support plate. Background Technology

[0002] In the sand and gravel processing industry, sand washing machines are crucial equipment for cleaning sand and gravel, and their screen structure has a decisive impact on washing efficiency and quality. Currently, sand washing machine screen structures on the market mainly fall into two types: integrated and separate. In integrated screen washing machines, the screen is fixedly connected to the machine body. The advantages of this structure are its simplicity and lower cost. However, the disadvantage of integrated screens is that replacement is very cumbersome once the screen is worn or damaged, requiring the disassembly of numerous parts of the sand washing machine, resulting in long maintenance times and reduced production efficiency. Separate screen washing machines allow for independent screen replacement, improving replacement efficiency. However, sand washing machines are usually designed with rapid water filtration in mind, so the screen typically allows water filtration from both the side and bottom. While side screen replacement is relatively convenient in sand washing machines with a split-screen structure, replacing the bottom screen is often cumbersome. In some designs, the bottom screen is not replaceable, meaning that if the bottom screen wears or is damaged, the entire screen support plate may need to be replaced, increasing maintenance costs and shortening the equipment's lifespan. This invention proposes a sand washing machine with a bent screen support plate, which has a simple structure, facilitates screen replacement, and is cost-effective, thereby improving production efficiency and reducing maintenance costs.

[0003] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a sand washing machine with a bent screen support plate, comprising a housing, a wheel installed inside the housing, the wheel including a central part, a connecting shaft fixed at the center of the central part, the shaft body of the connecting shaft being rotatably connected to the housing via a bearing, a drive mechanism installed at one end of the connecting shaft, partitions uniformly fixed on the outer surface of the central part, an annular mounting groove provided between adjacent partitions and the central part, a support plate body uniformly installed inside the annular mounting groove, the support plate body and the partitions being fastened together by bolts, the support plate body including a bottom plate, side plates and a plate edge, water permeable openings uniformly opened on the surfaces of the bottom plate and side plates, and a screen body fixed at the water permeable opening of the support plate body.

[0005] As a preferred technical solution of this utility model, the pallet body is arranged in a circle around the outer edge of the central part with the connecting shaft as the center.

[0006] As a preferred embodiment of the present invention, the bottom plate, side plate and edge of the pallet body are an integral structure, and the connection between the bottom plate, side plate and edge is formed by bending.

[0007] As a preferred embodiment of this utility model, the central surface of the wheel is uniformly provided with positioning grooves, which are adapted to the bending part of the pallet body.

[0008] As a preferred embodiment of this utility model, the edge of the plate is provided with a serrated structure.

[0009] As a preferred embodiment of this invention, the center of the wheel has a hollow structure.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: By adopting a bent-type integrated screen tray body structure, the entire screen tray body can be quickly disassembled and installed from the sand washing machine housing, significantly reducing the time required for screen replacement and thus improving production efficiency. Since the screen tray body can be replaced individually, it avoids the need to replace the entire disc due to screen damage, thereby reducing maintenance costs and material waste. Simultaneously, the integrated bent-type screen tray body structure breaks down the existing integral bottom screen structure into a modular structure combined with the side screens, ensuring rapid water filtration while facilitating the replacement and maintenance of the bottom screen. The structural design is simple, the manufacturing cost is reasonable, and it does not increase additional manufacturing costs due to complex structural design. Furthermore, it ensures the stability of sand washing efficiency and quality. Attached Figure Description
