Description

Technical Field

[0001] This utility model relates to the technical field of spiral sand washing machines, and in particular to a spiral sand washing machine for mining. Background Technology

[0002] Spiral sand washing machines are divided into single-spiral and double-spiral types. They are mainly used for washing, grading, and impurity removal in industries such as highways, hydropower, and construction, as well as for washing fine and coarse-grained materials. They feature low power consumption, high washing efficiency, good sealing structure, fully enclosed transmission equipment, and adjustable weir plates, ensuring high efficiency, durability, good cleaning and dewatering effects, and stable fine-grained products.

[0003] For example, patent (CN22991249U) discloses a spiral sand washing machine for mining, including a spiral sand washing machine body, a fixed frame, and a collection frame. A double-pipe is fixedly connected to the outer surface of the spiral sand washing machine body. A filter box is fixedly connected to the upper surface of the fixed frame. A water pump is installed on the outside of the filter box. A storage tank is fixedly connected to the bottom surface of the fixed frame. A connecting pipe is fixedly connected to the output end of the water pump. Two sets of support frames are fixedly connected to the bottom surface of the collection frame. Through the cooperation of the storage tank, centrifuge, telescopic plate, and filter frame, the wastewater generated from sand washing can be initially filtered. The centrifuge utilizes centrifugal force to separate the solid and liquid components of the wastewater. The cooperation between the water pump and the filter box further filters the wastewater, improving the filtration effect and achieving the goal of reusing water resources.

[0004] When using the above technology, the following technical problems were found in the existing technology: The existing technology uses a spiral sand washing machine to wash the raw materials, and then the washed raw materials fall into a screening screen for filtration. However, the long-term filtration of the screening screen is not conducive to the timely treatment of larger impurities, resulting in a large amount of impurities adhering to the screening screen, causing poor filtration effect. Furthermore, because the spiral sand washing machine washes the raw materials with water, the washed raw materials tend to accumulate into clumps, and the clumps of raw materials cannot be filtered through the screening screen. Vibration is required to break up the clumps in order to screen and filter more effectively. Therefore, we have designed a spiral sand washing machine for mining to provide an alternative technical solution to the above technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A spiral sand washing machine for mining includes a housing. Spiral sand washing slurry is rotatably connected to both sides of the housing. A perforation is provided at one end of the housing. A screening box is mounted at one end of the housing, and a screening screen is slidably connected inside the screening box. A drive mechanism for moving the screening screen is provided inside the housing. The drive mechanism includes a transmission rod, transmission wheels, and a C-type servo motor. The transmission rod is rotatably connected inside the screening box, and transmission wheels are fixed at both ends of the transmission rod. A C-type servo motor is mounted at one end of the housing, and the output end of the C-type servo motor is fixed to the transmission rod. The outer side of the transmission wheels is slidably connected to the screening screen.

[0007] In a preferred embodiment of the spiral sand washing machine for mining provided by this utility model, a transmission mechanism is provided at one end of the housing to drive two spiral sand washing slurries to rotate in opposite directions. The transmission mechanism includes a transmission gear, a main bevel gear, a driven bevel gear, and an A servo motor. One end of the spiral sand washing slurry passes through the housing and is fixed to the transmission gear. A U-shaped frame is fixed at one end of the housing. The two transmission gears are meshed and connected. An A servo motor is fixed at one end of the U-shaped frame. An A servo motor is fixed at the output end of the A servo motor. A main bevel gear is meshed and connected at one end of the A servo motor. One end of the main bevel gear is fixed to one of the transmission gears.

[0008] In a preferred embodiment of the spiral sand washing machine for mining provided by this utility model, the connection between the transmission rod and the transmission wheel is offset from the center of the transmission wheel.

[0009] In a preferred embodiment of the spiral sand washing machine for mining provided by this utility model, sliding columns are fixed on both sides of the inner side of the box, and guide blocks are slidably connected inside the sliding columns. Springs are installed at both ends of the inner side of the sliding columns, with the top end of the spring fixed to the guide block and the bottom end of the spring fixed to the sliding column.

[0010] In a preferred embodiment of the spiral sand washing machine for mining provided by this utility model, a lead screw is rotatably connected to one end of the screening box, a C servo motor is slidably connected to the top of the screening screen, the outer side of the lead screw is threadedly connected to the C servo motor, a B servo motor is mounted on one side of the screening box, and the output end of the B servo motor is fixed to the lead screw.

[0011] In a preferred embodiment of the spiral sand washing machine for mining provided by this utility model, a number of nozzle groups are fixed at one end of the top of the box.

[0012] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0013] At the same time, through the above technical solutions, this utility model has at least the following beneficial effects:

[0014] This utility model provides a spiral sand washing machine for mining. By rotating two spiral sand washing slurries in opposite directions, the washed raw materials fall into the screening box through the sluice. By starting a C servo motor, the transmission rod and transmission wheel are rotated, and the transmission wheel causes the screening screen to bounce up and down, thereby effectively preventing impurities on the screening screen from causing blockage. At the same time, the screening screen effectively breaks up the raw materials that have accumulated into clumps, thereby effectively improving the screening effect of the raw materials.

[0015] When the screen moves to its highest point, it comes into contact with servo motor C, which in turn activates servo motor B to rotate the lead screw. The lead screw then drives servo motor C to clean the impurities on the screen, thus maintaining the screening effect of the screen. Attached Figure Description

[0025] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0026] Please refer to Figures 1-4 A spiral sand washing machine for mining includes a housing 1. Spiral sand washing slurry 3 is rotatably connected to both sides inside the housing 1. A perforation 8 is opened at one end inside the housing 1. A screening box 2 is assembled at one end of the housing 1. A screening screen 11 is slidably connected inside the screening box 2. A drive mechanism for driving the screening screen 11 to oscillate is provided inside the housing 1. The drive mechanism includes a transmission rod 17, a transmission wheel 18, and a C-servo motor 19. The transmission rod 17 is rotatably connected inside the screening box 2. The transmission wheel 18 is fixed at both ends on the outer side of the transmission rod 17. The C-servo motor 19 is assembled at one end of the housing 1. The connection between the transmission rod 17 and the transmission wheel 18 is offset from the center of the transmission wheel 18. The output end of the C-servo motor 19 is fixed to the transmission rod 17. The outer side of the transmission wheel 18 is slidably connected to the screening screen 11.

[0027] When in use, when it is necessary to clean the raw materials, the two spiral mortar washing 3 are rotated in opposite directions, and the cleaned raw materials fall into the screening box 2 through the hole 8. The C servo motor 19 is started to drive the transmission rod 17 and the transmission wheel 18 to rotate. The transmission wheel 18 drives the screening screen 11 to bounce up and down, so that the screening screen 11 can screen the cleaned raw materials, thereby improving the quality of the screened raw materials.

[0028] Both sides of the inner side of the housing 1 are fixed with sliding columns 13. The sliding column 13 is slidably connected with a guide block 12. Both ends of the inner side of the sliding column 13 are equipped with springs 16. The top end of the spring 16 is fixed to the guide block 12, and the bottom end of the spring 16 is fixed to the sliding column 13.

[0029] Furthermore, the elasticity of the spring 16 drives the guide block 12 and the screen 11 to maintain contact with the transmission wheel 18, thereby increasing the frequency of the screen 11's up and down movement, ensuring that the screen 11 effectively screens the cleaned raw materials, and effectively breaks up the raw materials that have accumulated into clumps, preventing the raw materials from clogging above the screen 11 and avoiding reducing the screening efficiency of the screen 11.

[0030] One end of the housing 1 is provided with a transmission mechanism that drives two spiral mortar washing 3 to rotate in opposite directions. The transmission mechanism includes a transmission gear 5, a main bevel gear 7, a driven bevel gear 9, and an A servo motor 10. One end of the spiral mortar washing 3 passes through the housing 1 and is fixed with the transmission gear 5. A U-shaped frame 6 is fixed to one end of the housing 1. The two transmission gears 5 are meshed and connected. One end of the U-shaped frame 6 is fixed with the A servo motor 10. The output end of the A servo motor 10 is fixed with the A servo motor 10. One end of the A servo motor 10 is meshed and connected with the main bevel gear 7. One end of the main bevel gear 7 is fixed to one of the transmission gears 5.

[0031] Specifically, when the raw materials need to be cleaned, the A servo motor 10 is started to drive the bevel gear 9 and the main bevel gear 7 to rotate, so that the main bevel gear 7 drives the two transmission gears 5 and the spiral washing slurry 3 to rotate in opposite directions, so that the spiral washing slurry 3 can transport the cleaned raw materials into the screening box 2 and screen them through the screening screen 11 to improve the filtration quality of the raw materials.

[0032] One end of the screening box 2 is rotatably connected to a lead screw 14, and the top end of the screening mesh 11 is slidably connected to a C servo motor 19. The outer side of the lead screw 14 is threadedly connected to the C servo motor 19. A B servo motor 15 is mounted on one side of the screening box 2, and the output end of the B servo motor 15 is fixed to the lead screw 14.

[0033] Specifically, when the transmission wheel 18 drives the screen 11 to the highest turbulence position, the B servo motor 15 is started to drive the lead screw 14 to rotate. The lead screw 14 drives the C servo motor 19 to clean the impurities above the screen 11, thereby maintaining the screening effect of the screen 11.

[0034] Several nozzle groups 4 are fixed at one end of the top of the box 1. Water is delivered into the interior of the box 1 through the nozzle groups 4 to clean the raw materials.

Clearly, many modifications and variations can be made based on the content of this specification.
