Description

Technical Field

[0001] The utility model relates to the technical field of sand washing machines, in particular to a device for reducing the loss of fine sand. Background Art

[0002] Sand washing machines are used to wash sand and gravel (artificial sand and natural sand). They are widely used in industries such as sand and gravel fields, mining, building materials, transportation, chemical industry, water conservancy and hydropower, and concrete mixing plants. They remove impurities covering the surface of sand and gravel while simultaneously destroying the moisture layer surrounding the sand particles to facilitate dehydration, achieving efficient sand cleaning. Sand washing machines are available in two types: XS and XL. High-efficiency sand washing machines belong to the bucket wheel washing equipment series and offer the advantages of high processing capacity, low power consumption, and minimal sand loss during the washing process.

[0003] Patent No. CN201811386405.8 discloses an efficient sand washing machine with low sand loss. By setting a driving gear and a passive gear, the two sets of buckets rotate in opposite directions, which can not only make the sand mixing more even and the cleaning more thorough, but also save cleaning time and improve cleaning efficiency. By setting a through hole between the sand outlet and the bucket, fine sand with small particle size can be screened out and left in the sand washing pool. After the sand washing is completed, the fine sand is uniformly recovered and processed. A support device is set at the bottom of the sand washing pool. By adjusting the height of the telescopic legs, the sand washing pool can be tilted toward the water outlet, and water can be discharged without discharging the bottom sediment.

[0004] The high-efficiency sand washing machine with low sand loss disclosed in the above patent still requires manual work to tilt the sand washing tank slightly to pour out the dirty water after sand washing, and then manually tilt the sand washing tank completely to pour out the cleaned sand. It has a low degree of intelligence and wastes manpower. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 4 , a device for reducing the loss of fine sand shown in the figure includes a sand washing pool 5, and a hinge shaft assembly 9 is fixedly installed in the middle of the front and rear sides of the outer side wall of the sand washing pool 5 and is hinged to the inner side wall of the support 1 through the hinge shaft assembly 9. An electric telescopic rod 2 is installed at the bottom of the left side of the inner side wall of the support 1, and the top of the electric telescopic rod 2 is hinged to the left side of the outer side wall of the sand washing pool 5 through the hinge assembly 3 and the mounting plate 4. The right side of the inner side wall of the support 1 is slidably connected to the limiting cross bar 13, and the power input end of the limiting cross bar 13 is connected to the power output end of the linear displacement drive assembly. The device for reducing the loss of fine sand disclosed in the utility model hinges the sand washing pool 5 to the inner side wall of the support 1, and can drive the sand washing pool 5 to tilt to the right at a certain angle through the lifting assembly at the left end, so that dirty water can be automatically poured out, and the cleaned sand can also be automatically poured out.

[0020] Furthermore, a grinding wheel assembly 6 is rotatably installed on the inner wall of the sand washing tank 5, and the grinding wheel assembly 6 is rotatably installed on the inner wall of the fixed frame 7 through the rotating shaft at the axis center. The fixed frame 7 is installed outside the sand washing tank 5, and the power input end of the grinding wheel assembly 6 is connected to the power output end of the first motor 8, which is convenient for sand washing; further, the limiting cross bar 13 is slidably connected to the inner wall of the slide groove 12, and a slide groove 12 is opened on the right side of the support 1. The end of the limiting cross bar 13 is fixedly connected to the limiting plate 14, which is convenient for the smooth translation of the limiting cross bar 13; further, the linear displacement drive assembly includes a shell 11 fixedly installed on the right end of the outer wall of the support 1, and the inner wall of the shell 11 is rotatably connected to a threaded screw 15, and the power input end of the threaded screw 15 is connected to the power output end of the second motor 10 for convenient driving; further, the outer wall of the threaded screw 15 is threadedly connected to a screw sleeve 16, and the outer wall of the screw sleeve 16 is connected to the limiting cross bar 13 through a bearing 17 for convenient transmission.

[0021] In this solution, when in use, the device for reducing the loss of fine sand disclosed by the utility model hinges the sand washing pool 5 on the inner wall of the support 1, and can drive the sand washing pool 5 to tilt to the right at a certain angle through the lifting component at the left end, and can automatically pour out dirty water, and can also automatically pour out cleaned sand. When it is necessary to pour out the dirty water, the external power supply turns on the second motor 10 through the external switch, and the second motor 10 is controlled to rotate forward for a certain period of time through the program written in advance in the external control chip. The second motor 10 drives the threaded screw 15 to rotate, and drives the limit cross bar 13 to move downward a certain distance through the screw sleeve 16 and the bearing 17, so that the sand washing pool 5 can be slightly tilted. At this time, the electric telescopic rod 2 is controlled to extend a certain length, so that the sand washing pool 5 is slightly tilted to the right, and the dirty water inside is automatically poured out. Then, when the sand after cleaning the inside needs to be poured out, the second motor 10 is continued to be controlled to rotate forward for a certain length of time to make the limit cross bar 13 move downward to the bottom. The principle is the same as above. Then the electric telescopic rod 2 is controlled to extend to the longest length, so that the sand washing pool 5 is tilted to a greater extent, so that the cleaned sand in the sand washing pool 5 is automatically dumped out. The degree of intelligence is high. After dumping, the electric telescopic rod 2 is controlled to shorten and the second motor 10 is controlled to reverse to reset the sand washing pool 5 (the first motor 8, the second motor 10 and the electric telescopic rod 2 are all existing products on the market).
