[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figure 1-Figure 5A drum separation screen sand washing machine includes a sand washing machine shell 1 and a base 4. The sand washing machine shell 1 is made of high-strength and corrosion-resistant materials to ensure the long-term stable operation of the equipment. The base 4 is fixedly installed with the sand washing machine shell 1. The base 4 is welded from solid steel to provide stable support for the entire equipment. A second motor 3 and a separation screening machine 7 are installed on the base 4 to ensure a stable connection with the sand washing machine casing 1. A sand inlet trough 2 is fixedly installed on one side of the sand washing machine casing 1. The sand inlet trough 2 is located on one side of the sand washing machine casing 1 and is designed to be inclined to facilitate the smooth input of sand and gravel. A drum screen 8 is rotatably installed in the sand washing machine casing 1. The drum screen 8 is the core component of the sand washing machine. It is made of wear-resistant and corrosion-resistant materials, and the surface is densely covered with sieve holes. An auger 9 is arranged in the drum screen 8. The auger 9 is located inside the drum screen 8 and consists of spiral blades and a central axis. A second motor 3 is fixedly installed on the upper end of the other side of the base 4, and the output end of the second motor 3 is fixedly connected to the auger 9. A separation screening machine 7 is fixedly installed at the bottom of the base 4. The separation screening machine 7 performs secondary screening on the sand and gravel that have been preliminarily screened by the drum screen 8 to remove residual impurities and obtain higher quality sand and gravel products.

[0021] When in use, the sand and gravel to be washed are put into the drum screen 8 through the sand inlet trough 2. Since the sand inlet trough 2 is designed to be inclined, it can ensure that the sand and gravel enter the drum screen 8 smoothly. The second motor 3 is started, and the motor will drive the auger 9 to rotate. The spiral blades of the auger 9 will push the sand and gravel to move in the drum screen 8. The screen holes of the drum screen 8 will begin to screen out impurities such as soil and stone powder in the sand and gravel. The sand and gravel that have been preliminarily screened by the drum screen 8 will be discharged into the separation screening machine 7 through the discharge port of the drum screen 8. The separation screening machine 7 will use the vibration screening principle to perform secondary screening on the sand and gravel to remove residual impurities to ensure that high-quality sand and gravel products are finally obtained. The combined design of the drum screen 8 and the auger 9 enables the sand and gravel to fully contact the screen during the screening process, thereby improving the screening efficiency. At the same time, the driving action of the auger 9 accelerates the movement of sand and gravel in the drum screen 8, further improving the screening speed. After the preliminary screening of the drum screen 8 and the secondary screening of the separation screening machine 7, impurities such as soil and stone powder in the sand and gravel are effectively removed, ensuring the cleanliness and high quality of the final product.

[0022] like Figure 1 or Figure 5As shown, the separation screening machine 7 includes a collecting bucket 701 fixedly mounted on the base 4, the collecting bucket 701 is responsible for receiving the sand and gravel discharged from the drum screen 8, a conveyor belt 702, a water collecting trough 703, a collecting box 704 and a support column 705, the water collecting trough 703 is fixedly mounted on the collecting bucket 701, and is used to collect the moisture and impurities screened out from the sand and gravel, the water collecting trough 703 is fixedly mounted on the collecting box 704, the conveyor belt 702 is fixedly mounted inside the water collecting trough 703 and the collecting bucket 701, and is used to transport the sand and gravel from the collecting bucket 701 to the water collecting trough 703 for secondary screening, and the support column 705 is fixedly mounted on the collecting box 704. In the above-mentioned use process, after the sand and gravel are discharged from the drum screen 8, they first enter the collecting bucket 701, and are transported to the water collecting trough 703 under the action of the conveyor belt 702. In the water collecting tank 703, the sand and gravel are vibrated and screened again to remove the remaining impurities and moisture. The pure sand and gravel after the second screening falls into the collection box 704, completing the entire screening and washing process, which can further remove the remaining impurities and moisture and improve the purity of the sand and gravel products.

[0023] like Figure 3 As shown, the blades of the auger 9 are against the inner wall of the drum screen 8. During the above-mentioned use, the sand and gravel can move continuously and stably in the drum screen 8, which improves the screening efficiency and shortens the processing time. Due to the pushing effect of the auger 9, the sand and gravel can be evenly distributed in the drum screen 8, thereby improving the uniformity of screening.

[0024] like Figure 1 or Figure 3 As shown, a discharge port is provided at the bottom of the sand washing machine shell 1, and a slag discharge port 6 is provided on the other side. A slag discharge guide plate 5 is fixedly installed on the outer side of the slag discharge port 6. The bottom of the base 4 is sunken and fixedly connected to the separation and screening machine 7. In the above-mentioned use process, the sand washing machine is started, and the sand and gravel to be cleaned are added into the sand washing machine shell 1. The sand washing machine starts to work, and the sand and gravel are cleaned by means of water flow and vibration to remove impurities such as mud and stone powder. The cleaned sand and gravel are discharged through the discharge port and enter the separation and screening machine 7 for secondary screening. At the same time, the waste slag and impurities are discharged through the slag discharge port 6 and guided to the designated position by the slag discharge guide plate 5.

[0025] like Figure 3 As shown, the drum screen 8 is located on one side of the sand inlet trough 2 and is fixedly installed with a linkage rod 10, the base 4 is located on one side of the sand inlet trough 2 and is fixedly installed with a first motor 11, and the output end of the first motor 11 is connected to the linkage rod 10. During the above-mentioned use, the drum screen 8 is driven to rotate by the first motor 11, so that the sand and gravel can be fully rolled and screened on the screen, thereby improving the screening efficiency. The rotating screening method of the drum screen 8 can effectively remove large-particle impurities and soil in the sand and gravel, and improve the purity of the sand and gravel products.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
