[0002] Sand and gravel refers to a loose mixture of sand and crushed stone. Due to its good hardness and stable chemical properties, it is often used as a high-quality building material and concrete raw material and is widely used in housing, roads, highways, railways, engineering and other fields. In construction projects, sand and gravel usually need to be filtered to remove impurities before use.

However, there are still some shortcomings in the use of the device. When the device is in use, it is necessary to manually move the sand and gravel to the top of the device and then pour it into the device for filtering impurities. It is very laborious for personnel to move the sand and gravel to a high place, the labor intensity is high and the efficiency is low. Moreover, too much sand and gravel poured in at one time will cause them to pile up together, affecting the effect of screening and filtering impurities. At the same time, the filtering effect of a single filter plate is poor, which is inconvenient to use. Utility Model Content

It is very laborious for personnel to move sand and gravel to a high place, the labor intensity is high and the efficiency is low. In addition, too much sand and gravel poured in at one time will cause them to pile up together, affecting the effect of screening and filtering impurities. At the same time, the filtering effect of a single filter plate is poor, which is inconvenient to use.

[0013] This solution can facilitate the leveling of the sand and gravel on the conveyor belt so that the sand and gravel can evenly fall into the working box for screening and filtering, avoiding too much falling at one time, resulting in accumulation and affecting the filtering effect.

[0014] Preferred technical solution five: a sliding rod is fixedly connected to the upper surface of the support frame, a sliding sleeve is slidably sleeved on the surface of the sliding rod, and the sliding sleeve is fixedly connected to the other end of the connecting rod.

[0015] This solution can limit the moving trajectory of the connecting rod so that its height can be adjusted according to actual usage requirements, thereby adjusting the thickness of sand and gravel on the conveyor belt.

[0016] Compared with the prior art, the utility model provides a sand and gravel filtering device, which has the following beneficial effects: when in use, the user places the sand and gravel that need to be filtered on the top of the conveyor belt with a tool, and transports them through the conveyor belt. During the transportation process, the sand and gravel on the conveyor belt are smoothed by the blocking of the brush plate, so that they can be evenly transported to the inside of the working box, avoiding excessive one-time falling causing the sand and gravel to accumulate in one piece, affecting the filtering effect, and reducing the labor intensity of personnel. There is no need to move the sand and gravel to the top of the working box with effort.
