[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a spiral sand washing machine for mines.

[0026] The utility model provides Figure 1 A spiral sand washing machine for mining shown in the figure comprises a sand washing trough 1, a spiral blade 2 is arranged inside the sand washing trough 1, a rotating rod 3 is fixedly sleeved inside the spiral blade 2, the rod walls at both ends of the rotating rod 3 are rotatably connected to the inner wall of the sand washing trough 1 respectively, a motor 4 is fixedly arranged on the outer wall of one side of the sand washing trough 1, one end of the rotating rod 3 penetrates the side wall of the sand washing trough 1 on one side and is fixedly connected to the output end of the motor 4, two first fixed blocks 5 are symmetrically arranged on the front and rear sides of the lower surface of the sand washing trough 1, a cross beam 6 is horizontally fixedly arranged between the two first fixed blocks 5, and an angle adjustment mechanism is arranged below the cross beam 6.

[0027] In order to make the sand washing machine tilt at a suitable angle, such as Figure 2 ,3 As shown, the angle adjustment mechanism includes a base plate 24, a support column 8, a first connecting rod 7, an electric telescopic rod 13, a U-shaped plate 12, a second connecting rod 11, a second fixed block 10 and a slider 9. The rod wall of the first connecting rod 7 is sleeved in one end of the cross beam 6 and rotatably connected thereto, and the rod wall at the other end of the first connecting rod 7 is fixed on the support column 8. The support column 8 is rotatably connected to the cross beam 6 through the first connecting rod 7. A slide groove is provided at the other end of the cross beam 6, and the slider 9 is movably connected to the slide groove. The lower surface of the slider 9 is fixedly connected to the second fixed block 10. A through hole is provided inside the second fixed block 10, and the second connecting rod 11 is rotatably sleeved with the second fixed block 10 through the through hole. The rod walls at both ends of the second connecting rod 11 are respectively fixed on the inner wall of the U-shaped plate 12, and the lower surface of the U-shaped plate 12 is fixedly connected to the output end of the electric telescopic rod 13. The electric telescopic rod 13 and the support column 8 are horizontally symmetrically fixed on the upper surface of the base plate 24.

[0028] When the sand washing machine is working, it needs to be tilted, generally at 15-18 degrees. If the installation angle of the sand washing machine is too small, it is easy to be not cleaned properly, and if the angle is too large, more fine sand will be lost and the output will be reduced. When working, the electric telescopic rod 13 drives the slider 9 to move on the slide rail on the beam 6. Because the other side of the beam 6 is rotatably connected to the support column 8 through the first connecting rod 7, the beam 6 drives one side of the motor 4 of the sand washing trough 1 to rise, thereby realizing the angle adjustment.

[0029] In order to make the sand washing machine have a better cleaning effect, Figure 4 As shown, a water pump 14 is fixedly installed above the bottom plate 24, a first water pipe 15 is fixedly installed at the output end of the water pump 14, a telescopic tube 16 is fixedly installed on the first water pipe 15, a second water pipe 17 is installed at the other end of the telescopic tube 16, the second water pipe 17 is fixedly connected to the upper surface of the sand washing tank 1, and two valves 18 and a plurality of nozzles 19 are symmetrically installed front and back on the second water pipe 17.

[0030] The water output from the water pump 1 passes through the first water pipe 15 and the telescopic pipe 16 to the second water pipe 17, and is sprayed by multiple nozzles 19 on the second water pipe 17 to add water to the sand washing tank 1 and perform secondary cleaning on the sand. The telescopic pipe 16 connects the first water pipe 15 and the second water pipe 17 to prevent the water pipe from rupturing when the angle of the sand washing tank 1 is adjusted.

[0031] In order to discharge sewage and mud from the sand washing machine, Figure 2 As shown, an opening is provided on the side of the sand washing tank 1, a filter screen 20 is fixedly provided on the outer side of the opening, bolts 21 are provided on both horizontal sides of the filter screen 20, and the bolts 21 penetrate the filter screen 20 and are fixedly connected to the sand washing tank 1.

[0032] When the sand material is washed in the sand washing tank 1, mud and dust are mixed into mud and sewage and filtered through the filter 20. Since the filter 20 is fixed by bolts 21, it is easy to replace the filter 20 when it is damaged, and it is convenient to disassemble and assemble.

[0033] Finally, for feeding and discharging, such as Figure 1 As shown, a feed port 22 is provided above the sand washing tank 1 , and a discharge port 23 is provided below one side of the motor 4 of the sand washing tank 1 .

[0034] The sand enters the sand washing tank 1 from the feed port 22 , and the spiral blades 2 rotate to discharge the cleaned sand from the discharge port 23 .

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
