[0007] The working principle of the present invention is as follows: sand and gravel are stored in a storage barrel. When working, the sand and gravel are fed into the filter cylinder through the feeding assembly. The rotating motor drives the filter cylinder to rotate. During the rotation, the discharge pipe of the lower fan-shaped cylinder is located in the aggregate trough. The sand and gravel slowly fall from the upper fan-shaped cylinder through the cylinder into the lower fan-shaped cylinder. After being screened by the filter screen, the sand and gravel fall into the aggregate trough through the discharge pipe. They are uniformly collected and discharged through the discharge pipe. When the rotation exceeds 90°, the working modes of the two fan-shaped cylinders are exchanged, so that the sand and gravel flow back from the cylinder.

The U-shaped closing frame is fixedly connected to the slide groove, and the front and rear sides of the U-shaped closing frame and the closing plate are in contact with the slide groove.

[0011] With the above structure, during the feeding and turning process, under the action of sand and gravel falling and turning, the spring can make the scoring plate vibrate and beat the sand and gravel, which can not only promote the separation of sand and gravel from debris, but also make the sand and gravel scattered more dispersed, further improving the quality of filtration.

Then the push rod squeezes the sealing plug and pushes the sealing plug open, thereby realizing the connection between the discharge pipe and the discharge head, realizing normal feeding operation and preventing unfiltered sand and gravel from being directly discharged from the discharge port. After the feeding is completed, under the action of the second elastic component, the first sealing plate seals the discharge pipe and opens the discharge port at the same time, so that the sand and gravel can enter the discharge pipe through the discharge port after filtering, and then be discharged into the collecting trough from the other end of the discharge pipe, which is convenient for collecting the filtered sand and gravel.

The two working modes can be selected according to needs.

Sand and gravel are stored in the storage barrel. When working, the sand and gravel are fed into the filter cylinder through the feeding assembly. The rotating motor drives the filter cylinder to rotate. During the rotation, the discharge pipe of the lower fan-shaped cylinder is located in the aggregate trough. The sand and gravel slowly fall from the upper fan-shaped cylinder through the cylinder into the lower fan-shaped cylinder. After being screened by the filter net, they fall into the aggregate trough through the discharge pipe. They are uniformly collected and discharged through the discharge pipe. When the rotation exceeds 90°, the working modes of the two fan-shaped cylinders are exchanged, so that the sand and gravel flow back from the cylinder. In this way, the filtration operation is completed. Through this filtration method, slow feeding filtration can be achieved, and the efficiency and quality of filtration can be improved. In addition, the sand and gravel can be turned over by cyclic flipping to prevent debris from clogging the filter net and affecting the efficiency and quality of filtration.

The first bevel gear can be driven to rotate by a driving motor, and the first bevel gear can drive the threaded rod to rotate through the second bevel gear, so that the threaded rod drives the adjustment plate to move, so that the degree to which the adjustment plate extends out of the support seat changes, thereby realizing the change of the falling speed of the sand and gravel flow to meet different filtering needs. At the same time, during filtering, the adjustment plate can be reciprocated by the forward and reverse rotation of the driving motor cycle, thereby improving the filtering effect.

In the process of unloading and turning, when the sand and gravel fall, And under the action of flipping, the spring 20 can make the scoring plate 15 vibrate, and the sand and gravel can be slapped, which can not only promote the separation of sand and gravel from debris, but also make the sand and gravel scattered more dispersed, further improving the quality of filtration. After rotating more than 90°, the working modes of the two fan-shaped cylinders 10 are exchanged, so that the sand and gravel flow back from the cylinder 9, and the cycle is repeated to complete the filtration operation. Through this filtration method, slow feeding filtration can be achieved, and the efficiency and quality of filtration can be improved. The sand and gravel can be turned over by circulating and flipping to prevent debris from clogging the filter screen 11 and affecting the efficiency and quality of filtration. At the same time, in the process of flipping The sand and gravel can collide in the process, so that the separation effect of impurities and sand and gravel is good, and the formation of lumps is prevented. When the filtering requirements are different, the first bevel gear 45 is driven to rotate by the driving motor, and the first bevel gear 45 drives the threaded rod 46 to rotate through the second bevel gear 48, so that the threaded rod 46 drives the adjustment plate 44 to move, so that the degree to which the adjustment plate 44 extends out of the support seat 13 changes, thereby realizing the change of the sand and gravel flow and falling speed to meet different filtering requirements. At the same time, during filtering, the adjustment plate 44 can also be reciprocated by the forward and reverse rotation of the driving motor cycle, thereby improving the filtering effect. The two working modes can be selected according to needs.

[0057] In summary, by configuring the filter cartridge 5, the first half ring seat 7, the second half ring seat 30 and other structures, it is possible to prevent the filter screen 11 from being blocked by debris such as stones while improving the efficiency and quality of filtration.
