[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A sweet potato washing and filtering device includes a washing chamber, a pushing mechanism fixedly connected to the upper left and right sides of the inner wall of the washing chamber, a rotating mechanism provided on the inner wall of the pushing mechanism on the left side, a plurality of hair roller mechanisms in a semi-circular array rotatably connected to the front and rear sides of the inner wall of the washing chamber, a water spraying mechanism fixedly connected to the upper front and rear sides of the washing chamber, and a filtering mechanism fixedly connected to the lower part of the washing chamber.

[0008] A further improvement of the present invention is that the pushing mechanism includes two rectangular blocks, each of which has a T-shaped sliding groove on its opposite surface and a semi-circular groove below its opposite surface. A T-shaped sliding block is slidably connected to the inner wall of the T-shaped sliding groove, and a pushing plate is fixedly connected to the opposite surface of the two T-shaped sliding blocks. A rubber layer is fixedly connected to the front of the pushing plate, and the opposite sides of the two rectangular blocks are fixedly connected to the upper left and right sides of the inner wall of the square cleaning chamber.

[0009] A further improvement of the present invention is that the rotating mechanism includes a threaded rod, a motor is fixedly connected to the rear of the threaded rod, the outer wall of the threaded rod is threadedly connected to the inner wall of the left T-shaped sliding block, the front and rear outer walls of the threaded rod are rotatably connected to the front and rear inner walls of the square cleaning chamber, and the front of the motor is fixedly connected to the rear of the square cleaning chamber.

[0010] A further improvement of this utility model is that: the brush roller mechanism includes several brush rollers arranged in a semi-circular array, and a circular rotating shaft is fixedly connected to both the front and rear sides of each brush roller. The outer walls of the several circular rotating shafts at the rear are fixedly connected to meshing gears. The rearmost circular rotating shaft passes through the rear of the square cleaning chamber to the outside. A second motor is fixedly connected to the rear of the rearmost circular rotating shaft. The outer walls of the front and rear circular rotating shafts are rotatably connected to the front and rear inner walls of the square cleaning chamber. The outer walls of the meshing gears are rotatably connected to the rear inner wall of the square cleaning chamber.

[0011] A further improvement of the present invention is that the water spraying mechanism includes a water pump, the output end of the water pump is fixedly connected to a water outlet pipe, a plurality of nozzles are fixedly connected below the position above the square cleaning chamber of the water outlet pipe, fixed columns are fixedly connected on both sides below the positions in front of and behind the plurality of nozzles of the water outlet pipe, the lower part of the fixed columns is fixedly connected to the upper part of the square cleaning chamber, a water inlet pipe is fixedly connected to the input end of the water outlet pipe, and the front of the water pump is fixedly connected to the rear of the square cleaning chamber.

[0012] A further improvement of this utility model is that the filtration mechanism includes a drain pipe, the outer wall of one end of the drain pipe is fixedly connected to the inner wall of the outlet, the other end of the drain pipe is fixedly connected to a square filter chamber, a plurality of sliding grooves are provided above the square filter chamber, a square frame is slidably connected to the inner wall of the sliding grooves, filter screens of different diameters are fixedly connected to the inner walls of the plurality of square frames, a handle is fixedly connected to the top of the square frame, a second drain pipe is fixedly connected to the rear of the square filter chamber, a water valve is fixedly connected to the upper outer wall of the second drain pipe, the other end of the second drain pipe is fixedly connected to the lower part of the inlet pipe, and the lower part of the square filter chamber is fixedly connected to the upper part of the fixed plate.

[0013] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0014] 1. The motor output drives the threaded rod to rotate, causing it to rotate with the T-shaped sliding block on the left side. After sliding with the T-shaped sliding groove, the rod moves, which in turn moves the pusher plate and rubber layer, pushing the sweet potatoes towards the semi-circular gate. The semi-circular gate then rotates with the square cleaning chamber, pushing the sweet potatoes out. Traditional roller-type potato cleaning devices may require manual potato unloading. Through the pusher and rotating mechanisms, automatic and continuous potato unloading can be achieved, allowing the cleaning work to proceed without interruption. The pusher and rotating mechanisms can stably transport potatoes out of the cleaning area at a set speed and quantity, thereby greatly increasing the amount of potatoes cleaned per unit time, thus reducing labor costs and labor intensity.

[0015] 2. During use, the water used to wash the sweet potatoes flows from the spray mechanism into the drain pipe and then into the square filter chamber. The water passes through different sized filter screens. The first-stage filter uses a coarse screen with larger mesh openings to initially filter out large pieces of soil, sand, and other large impurities from the surface of the sweet potatoes, preventing these large particles from clogging or damaging the equipment during subsequent washing and filtration processes. The second-stage filter uses a medium-fine screen with slightly smaller mesh openings to further filter out smaller particles of soil and impurities, significantly reducing the impurity content in the washing water. The third-stage filter uses a fine screen with extremely small mesh openings, primarily to intercept any remaining fine sand particles. The filtered water flows into the second drain pipe. Then, the water valve is opened, allowing the water pump output to draw the filtered water from the second drain pipe into the inlet pipe, ensuring that the final discharged water is relatively clear and recyclable. Alternatively, by grasping the handle and moving it upwards, the square frame slides against the sliding groove and can be removed for cleaning, preventing impurities from accumulating and affecting the filtration effect and water flow rate.

[0024] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0025] like Figure 1-2 As shown, this utility model provides a sweet potato washing and filtering device, including a washing chamber 1, a pushing mechanism 2 fixedly connected to the upper left and right sides of the inner wall of the washing chamber 1, a rotating mechanism 3 provided on the inner wall of the left pushing mechanism 2, a number of hair roller mechanisms 4 in a semi-circular array rotatably connected to the front and rear sides of the inner wall of the washing chamber 1, a water spraying mechanism 5 fixedly connected to the upper front and rear sides of the washing chamber 1, and a filtering mechanism 6 fixedly connected to the lower part of the washing chamber 1.

[0026] The automatic and continuous discharge of potatoes can be achieved through the pushing mechanism 2 and the rotating mechanism 3, so that the washing work can be carried out without interruption. The pushing mechanism 2 and the rotating mechanism 3 can stably transport potatoes out of the washing area at a set speed and quantity, thereby greatly increasing the washing capacity of potatoes per unit time, thereby reducing labor costs and reducing labor intensity. The filtration mechanism 6 can perform multi-stage filtration of the water after washing sweet potatoes to ensure that the final discharged water is relatively clear and can be recycled. The filtration mechanism 6 can also be disassembled and cleaned to prevent the accumulation of impurities from affecting the filtration effect and water flow speed.

[0027] like Figure 3-4The present invention provides a technical solution: a cleaning chamber 1 includes a square cleaning chamber 11, a pyramidal water outlet chamber 13 is fixedly connected to the bottom of the square cleaning chamber 11, a water outlet 14 penetrating the inside and outside is opened in the middle of the pyramidal water outlet chamber 13, a plurality of support legs 15 are fixedly connected to the bottom of the square cleaning chamber 11, a fixing plate 16 is fixedly connected to the lower side of the opposite side of the rear support legs 15, a semi-circular door 12 is rotatably connected to the left and right sides of the front inner wall of the square cleaning chamber 11, and a pushing mechanism 2 includes two rectangular blocks 21, a T-shaped sliding groove 23 is opened on the opposite side of the two rectangular blocks 21, and a semi-circular door 12 is opened on the lower side of the opposite side of the two rectangular blocks 21. The inner wall of the groove 22 and the T-shaped sliding groove 23 is slidably connected to a T-shaped sliding block 24. The two T-shaped sliding blocks 24 are fixedly connected to a pusher plate 25 on opposite sides. A rubber layer 26 is fixedly connected to the front of the pusher plate 25. The two rectangular blocks 21 are fixedly connected to the upper left and right sides of the inner wall of the square cleaning chamber 11 on opposite sides. The rotating mechanism 3 includes a threaded rod 31. A motor 32 is fixedly connected to the rear of the threaded rod 31. The outer wall of the threaded rod 31 is threadedly connected to the inner wall of the left T-shaped sliding block 24. The front and rear outer walls of the threaded rod 31 are rotatably connected to the front and rear inner walls of the square cleaning chamber 11. The front of the motor 32 is fixedly connected to the rear of the square cleaning chamber 11.

[0028] The pushing mechanism 2 and the rotating mechanism 3 can push out sweet potatoes. In use, the output end of the motor 32 drives the threaded rod 31 to rotate, so that it rotates with the threaded T-shaped sliding block 24 on the left side, and then slides with the T-shaped sliding groove 23 to move. This moves the pushing plate 25 and the rubber layer 26 to push the sweet potatoes towards the semi-circular gate 12. After the semi-circular gate 12 rotates with the square cleaning chamber 11, the sweet potatoes are pushed out. Traditional brush roller potato cleaning devices may require manual potato unloading. Through the pushing mechanism 2 and the rotating mechanism 3, the potatoes can be automatically and continuously discharged, so that the cleaning work can be carried out without interruption. The pushing mechanism 2 and the rotating mechanism 3 can stably transport potatoes out of the cleaning area at a set speed and quantity, thereby greatly increasing the amount of potatoes cleaned per unit time, thereby reducing labor costs and reducing labor intensity.

[0029] like Figure 5 As shown, this utility model provides a technical solution: the brush roller mechanism 4 includes several brush rollers 41 arranged in a semi-circular ring array. Circular rotating shafts 42 are fixedly connected to the front and rear of the brush rollers 41. The outer walls of the several circular rotating shafts 42 at the rear are fixedly connected to meshing gears 43. The rearmost circular rotating shaft 42 passes through the rear of the square cleaning chamber 11 to the outside. A motor 44 is fixedly connected to the rear of the rearmost circular rotating shaft 42. The outer walls of the front and rear circular rotating shafts 42 are rotatably connected to the front and rear inner walls of the square cleaning chamber 11. The outer walls of the meshing gears 43 are rotatably connected to the rear inner wall of the square cleaning chamber 11.

[0030] The output of motor 44 drives the rightmost circular rotating shaft 42 to rotate, causing the meshing gears 43 to mesh with each other, driving the other circular rotating shafts 42 and the brush roller 41 to rotate and clean the sweet potatoes.

[0031] like Figure 6 As shown, this utility model provides a technical solution: the water spraying mechanism 5 includes a water pump 51, the output end of the water pump 51 is fixedly connected to a water outlet pipe 52, the water outlet pipe 52 is positioned above the square cleaning chamber 11 and is fixedly connected to several nozzles 54 below it, the water outlet pipe 52 is positioned in front of and behind the several nozzles 54 and is fixedly connected to two fixed columns 53 on both sides below it, the fixed columns 53 are fixedly connected to the top of the square cleaning chamber 11 below it, the input end of the water outlet pipe 52 is fixedly connected to a water inlet pipe 55, and the front of the water pump 51 is fixedly connected to the rear of the square cleaning chamber 11.

[0032] After the water inlet pipe 55 is connected to the water source, the water pump 51 draws water from the water inlet pipe 55 and delivers it to the water outlet pipe 52, where it is sprayed out from the nozzle 54 to clean the sweet potatoes.

[0033] like Figure 7 The present invention provides a technical solution: the filtration mechanism 6 includes a drain pipe 61, the outer wall of one end of the drain pipe 61 is fixedly connected to the inner wall of the outlet 14, the other end of the drain pipe 61 is fixedly connected to a square filter chamber 62, a plurality of sliding grooves 63 are provided above the square filter chamber 62, a square frame 64 is slidably connected to the inner wall of the sliding grooves 63, filter screens 65 of different diameters are fixedly connected to the inner walls of the plurality of square frames 64, a handle 66 is fixedly connected to the top of the square frame 64, a second drain pipe 67 is fixedly connected to the rear of the square filter chamber 62, a water valve 68 is fixedly connected to the outer wall above the second drain pipe 67, the other end of the second drain pipe 67 is fixedly connected to the bottom of the inlet pipe 55, and the bottom of the square filter chamber 62 is fixedly connected to the top of the fixing plate 16.

[0034] The filtration unit 6 can perform multi-stage filtration of the washed water for recycling. During use, the water used to wash the sweet potatoes is sprayed from the outlet 14 into the drain pipe 61 via the spray mechanism 5, and then enters the square filter chamber 62. It is filtered through filter screens 65 of different diameters. The first-stage filter screen 65 is a coarse filter with larger mesh openings, which can initially filter out large pieces of soil, sand, and larger impurities from the surface of the sweet potatoes, preventing these large particles from clogging or damaging the equipment in subsequent washing and filtration stages. The second-stage filter screen 65 is a medium-fine filter with slightly smaller mesh openings, which can further filter out smaller particles of soil and impurities, making the water more hygienic. The impurity content in the cleaning water flow is greatly reduced. The third-stage filter screen 65 is a fine filter screen with extremely small mesh, mainly used to intercept any fine mud and sand particles that may remain. The filtered and clear water flows into the second drain pipe 67. Then, the water valve 68 is opened, so that the output end of the water pump 51 draws the filtered and clear water from the second drain pipe 67 into the inlet pipe 55, thereby ensuring that the final discharged water is relatively clear and can be recycled. Alternatively, by grasping the handle 66 and moving it upward, the square frame 64 can slide against the sliding groove 63 and be removed, allowing the filter screen 65 to be cleaned to prevent the accumulation of impurities from affecting the filtration effect and water flow speed.

[0035] The working principle of the sweet potato cleaning and filtering device is explained in detail below: After the water inlet pipe 55 is connected to the water source, the water pump 51 draws water from the water inlet pipe 55 and delivers it to the water outlet pipe 52, and then sprays it out from the nozzle 54 to clean the sweet potatoes.

[0036] The output of motor 44 drives the rightmost circular rotating shaft 42 to rotate, causing the meshing gears 43 to mesh with each other, driving the other circular rotating shafts 42 and the brush roller 41 to rotate and clean the sweet potatoes.

[0037] The pushing mechanism 2 and the rotating mechanism 3 can push out sweet potatoes. In use, the output end of the motor 32 drives the threaded rod 31 to rotate, so that it rotates with the threaded T-shaped sliding block 24 on the left side, and then slides with the T-shaped sliding groove 23 to move. This moves the pushing plate 25 and the rubber layer 26 to push the sweet potatoes towards the semi-circular gate 12. After the semi-circular gate 12 rotates with the square cleaning chamber 11, the sweet potatoes are pushed out. Traditional brush roller potato cleaning devices may require manual potato unloading. Through the pushing mechanism 2 and the rotating mechanism 3, the potatoes can be automatically and continuously discharged, so that the cleaning work can be carried out without interruption. The pushing mechanism 2 and the rotating mechanism 3 can stably transport potatoes out of the cleaning area at a set speed and quantity, thereby greatly increasing the amount of potatoes cleaned per unit time, thereby reducing labor costs and reducing labor intensity.

[0038] The filtration unit 6 can perform multi-stage filtration of the washed water for recycling. During use, the water used to wash the sweet potatoes is sprayed from the outlet 14 into the drain pipe 61 via the spray mechanism 5, and then enters the square filter chamber 62. It is filtered through filter screens 65 of different diameters. The first-stage filter screen 65 is a coarse filter with larger mesh openings, which can initially filter out large pieces of soil, sand, and larger impurities from the surface of the sweet potatoes, preventing these large particles from clogging or damaging the equipment in subsequent washing and filtration stages. The second-stage filter screen 65 is a medium-fine filter with slightly smaller mesh openings, which can further filter out smaller particles of soil and impurities, making the water more hygienic. The impurity content in the cleaning water flow is greatly reduced. The third-stage filter screen 65 is a fine filter screen with extremely small mesh, mainly used to intercept any fine mud and sand particles that may remain. The filtered and clear water flows into the second drain pipe 67. Then, the water valve 68 is opened, so that the output end of the water pump 51 draws the filtered and clear water from the second drain pipe 67 into the inlet pipe 55, thereby ensuring that the final discharged water is relatively clear and can be recycled. Alternatively, by grasping the handle 66 and moving it upward, the square frame 64 can slide against the sliding groove 63 and be removed, allowing the filter screen 65 to be cleaned to prevent the accumulation of impurities from affecting the filtration effect and water flow speed.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
