Description

Technical Field

[0001] The present invention belongs to the technical field of sand and gravel filtration, and relates to a rapid impurity filtration device, in particular to a rapid sand and gravel impurity filtration device for zoo construction projects. Background Art

[0002] A zoo construction project refers to the engineering entity formed by the construction of various animal housing buildings and their ancillary facilities and the installation of supporting lines, pipelines, and equipment. When constructing a zoo building project, sand and gravel are required as building materials. Since large stones are often contained in the sand and gravel, a sand and gravel impurity filtration device is needed to filter it.

[0003] After retrieval, as disclosed in a Chinese patent document, a rapid sand and gravel impurity filtration device for construction projects [Application No.: 202411352433.3; Publication No.: CN 118950467 A]. This impurity filtration device includes an installation sleeve, an impurity filtration component, and a discharge component. The impurity filtration component is fixed on the inner wall of the top end of the installation sleeve; the impurity filtration component includes a support plate, a cylinder, a first limit ball, a support rod, a second limit ball, a rotating shaft, a filtration tank, a filtration groove, a filter screen, a first limit groove, and a second limit groove. A filtration tank is fixed on the inner wall of one side of the installation sleeve, and rotating shafts are symmetrically and fixedly connected to the outer wall of one side of the filtration tank, and the other ends of the rotating shafts are rotatably connected to the inside of the filtration tank; this invention adopts an impurity filtration device that can filter sand and gravel by itself without manual assistance, improving the filtration efficiency and reducing the workload of the staff, but also reducing the work efficiency; it also adopts a discharge device that can discharge impurities such as stones and branches without manual picking, avoiding delaying the next filtration operation and improving the use effect of the device.

[0004] Although the impurity filtration device disclosed in this patent can discharge impurities such as stones and branches through the discharge device, when filtering, a large amount of sand and gravel is directly poured into the filtration tank for filtration. On the one hand, the accumulation of a large amount of sand and gravel will affect the filtration effect. On the other hand, when filtering, sundries such as stones will accumulate on the filter screen, blocking some of the filtration holes and affecting the filtration quality. Summary of the Invention

[0005] The purpose of the present invention is to address the above problems existing in the prior art and propose a rapid sand and gravel impurity filtration device for zoo construction projects. The technical problem to be solved by this invention is: how to prevent the blockage of the filter screen by sundries such as stones while improving the filtration efficiency and quality.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A rapid sand and gravel filtering device for zoo construction projects, comprising a first support and a second support. A storage bucket is fixed on the first support, and a mounting frame is fixed on the second support. A rotating motor is fixed on the mounting frame, and a rotating shaft is fixed at the output shaft end of the rotating motor. The rotating shaft is fixedly connected to the mounting frame, and a filtering cylinder is fixed on the rotating shaft. The filtering cylinder is composed of a cylindrical barrel and two sector barrels. The two sector barrels are respectively fixed at both ends of the cylindrical barrel. A filter screen is fixed at one end of the sector barrel far from the cylindrical barrel. A discharge pipe is fixed at the end of the sector barrel far from the cylindrical barrel. The end of the discharge pipe located inside the sector barrel passes through the filter screen, and a discharge port is formed on the side of the discharge pipe. The discharge port is located inside the sector barrel and is close to the end of the sector barrel far from the cylindrical barrel. A first semi-circular seat is fixed on the second support, and an aggregate groove is formed on the upper side of the first semi-circular seat. The other end of the discharge pipe is located in the aggregate groove. A discharge pipe is fixed at the lower end of the first semi-circular seat. A switching component is arranged inside the discharge pipe, and a feeding component is arranged at the lower end of the storage bucket.

[0008] The working principle of the present invention is as follows: Sand and gravel are stored in the storage bucket. During operation, the sand and gravel are fed into the filtering cylinder through the feeding component. The rotating motor drives the filtering cylinder to rotate. During the rotation, the discharge pipe of the lower sector barrel is located in the aggregate groove. The sand and gravel slowly fall from the upper sector barrel through the cylindrical barrel into the lower sector barrel, and after being screened by the filter screen, they fall into the aggregate groove through the discharge pipe, are collected uniformly and discharged through the discharge pipe. When the rotation exceeds 90°, the working modes of the two sector barrels are exchanged, so that the sand and gravel flow back from the cylindrical barrel. In this way, the filtration operation is completed through this filtering method. Slow feeding filtration can be realized, the filtration efficiency and quality can be improved, and through the cyclic flipping method, the sand and gravel can be turned over, preventing impurities from blocking the filter screen and affecting the filtration efficiency and quality. At the same time, during the flipping process, the sand and gravel can collide, so that the separation effect of impurities and sand and gravel is good, and the generation of caking is prevented.

[0009] A support seat is slidably connected inside the cylindrical barrel. A support rod is fixed on the support seat, and the other end of the support rod is fixed with a material distribution plate. A number of material distribution holes are formed on the material distribution plate.

[0010] With the above structure, when the sand and gravel are discharged, through the cooperation of the material distribution plate and the material distribution holes, the sand and gravel can be scattered and sprinkled on the filter screen, preventing the sand and gravel from accumulating in the middle of the filter screen and affecting the filtration effect.

[0011] A chute is formed inside the cylindrical barrel. A slider is slidably connected inside the chute. The slider is fixedly connected to the support seat through a connecting rod. Springs are fixed at both the upper and lower ends of the slider, and the other ends of the springs are fixedly connected to the chute. Sealing plates are fixed on both sides of the upper side of the slider. A U-shaped sealing frame is slidably connected to the sealing plates. The U-shaped sealing frame is fixedly connected to the chute, and the front and rear sides of the U-shaped sealing frame and the sealing plates are in contact with the chute.

[0012] With the above structure, during the blanking and flipping processes, under the action of the falling and flipping of the sand and gravel, the feeding plate can be vibrated in cooperation with the spring, and the sand and gravel can be slapped, which can not only promote the separation of the sand and gravel from the sundries, but also make the sand and gravel scatter more dispersedly, further improving the filtering quality.

[0013] The feeding component includes a feeding pipe, which is fixedly connected to the lower end of the storage pipe. A second semi-ring seat is fixed to the lower end of the feeding pipe. A feeding cavity is formed inside the second semi-ring seat. A through groove is formed on the lower side of the feeding cavity. A feeding seat that is slidably connected to the feeding cavity is slidably connected inside the through groove. An electric telescopic rod is fixed to the lower side of the feeding seat. A feeding head is fixed to the lower end of the electric telescopic rod. A telescopic pipe is fixed to the feeding head. A transmission pipe is slidably connected to the telescopic pipe. The transmission pipe is fixedly connected to the feeding seat. A shielding component is arranged between the feeding seat and the through groove.

[0014] With the above structure, during operation, when one of the sector cylinders disengages from the first semi-ring seat and moves to a designated position, the electric telescopic rod drives the feeding head to move, so that the feeding head enters the discharge pipe, thereby realizing the feeding operation of the sector cylinder. And during feeding, under the action of the through groove, the feeding head can move along with the sector cylinder, so as not to affect the normal rotary filtering operation, achieving the effect of feeding and screening simultaneously, greatly ensuring the working efficiency.

[0015] The shielding component includes an arc-shaped plate. Arc-shaped guiding grooves are formed on both the front and rear sides of the through groove. The ends of the arc-shaped guiding grooves extend out of the second semi-ring seat. There are two arc-shaped plates, which are respectively fixed to the left and right sides of the feeding seat. The arc-shaped plates are slidably connected to the arc-shaped guiding grooves.

[0016] With the above structure, while ensuring the sliding feeding of the feeding seat in the through groove, the sealing property of the through groove can be ensured, preventing the sand and gravel from falling from the through groove and ensuring the normal progress of the work.

[0017] A feeding cavity is formed inside the feeding head. A communication port is formed at the lower end of the feeding cavity. A first elastic component is fixed inside the feeding cavity. An L-shaped rod is fixed to the first elastic component. The other end of the L-shaped rod is fixed with a sealing plug, and the sealing plug is inserted into the communication port.

[0018] With the above structure, when there is no feeding, under the action of the first elastic component, the sealing plug is inserted into the communication port to block the communication port, so that the sand and gravel will not flow out of the discharge head, preventing the sand and gravel from spilling outside. During feeding, when the discharge head is connected to the discharge pipe, under the action of the discharge pipe, the sealing plug is pushed open, thereby realizing the connection between the discharge pipe and the discharge head and realizing the normal feeding operation. This structure is simple and convenient, not only has a low failure rate, but also is fully automated throughout the process and has strong practicability.

[0019] The switching component includes a second elastic component fixed inside the discharge pipe. A lifting rod is fixed on the second elastic component, a top rod is fixed on the lifting rod, a first sealing plate is fixed at the lower end of the top rod, a support rod is fixed in the middle of the top rod, and a second sealing plate is fixed at the other end of the support rod.

[0020] With the above structure, during feeding, the discharge head enters the discharge pipe and presses the lifting rod, causing the top rod to move. As a result, while the first sealing plate disengages from the discharge pipe, the second sealing plate seals the discharge port. Then, the top rod presses the plug, pushing the plug open, thus realizing the connection between the discharge pipe and the discharge head. While realizing normal feeding operation, it prevents unfiltered sand and gravel from being directly discharged from the discharge port. After feeding is completed, under the action of the second elastic component, the first sealing plate seals the discharge pipe, and at the same time, the discharge port is opened, enabling the sand and gravel to enter the discharge pipe through the discharge port after filtration and then be discharged into the aggregate tank from the other end of the discharge pipe, facilitating the collection of the filtered sand and gravel. This structure realizes the free switching between the feeding and filtering modes, provides great convenience for the flipping and filtering operation, has a simple structure, high compactness, does not require the cooperation of electrical components, and has a low failure rate.

[0021] A driving cavity is formed inside the support seat. A driving component is arranged inside the driving cavity. The periphery of the driving cavity is slidably connected with an adjusting plate. The other end of the adjusting plate extends out of the support seat, and the adjusting plate is connected with the driving component.

[0022] The driving component includes a driving motor fixed inside the driving cavity. A first bevel gear is fixed at the output shaft end of the driving motor. Four bearing seats are fixed inside the driving cavity. A second bevel gear is rotatably connected to the bearing seat. The first bevel gear meshes with the second bevel gear. A threaded rod is fixedly connected to the second bevel gear through a transmission shaft. A threaded groove is formed inside the adjusting plate, and the threaded rod is in threaded connection with the threaded groove.

[0023] With the above structure, the driving motor can drive the first bevel gear to rotate. The first bevel gear drives the threaded rod to rotate through the second bevel gear, so that the threaded rod drives the adjusting plate to move, changing the degree to which the adjusting plate extends out of the support seat, thus realizing the change of the falling speed of the sand and gravel flow and meeting different filtering requirements. At the same time, during filtering, the driving motor can also rotate forward and backward cyclically, causing the adjusting plate to move reciprocally, thereby improving the filtering effect. The two working modes can be selected according to requirements.

[0024] Compared with the prior art, the rapid sand and gravel impurity filtering device for the zoo construction project has the following advantages:

[0025] 1. Sand and gravel are stored in a storage bucket. During operation, the sand and gravel are sent into a filter cylinder through a feeding assembly. A rotating motor drives the filter cylinder to rotate. During the rotation, the discharge pipe of the lower sector cylinder is located in the aggregate chute. The sand and gravel slowly fall from the upper sector cylinder through the cylinder into the lower sector cylinder. After being screened by a filter net, they fall into the aggregate chute through the discharge pipe, are collected uniformly and discharged through a discharge pipe. When the rotation exceeds 90°, the working modes of the two sector cylinders are exchanged, causing the sand and gravel to flow back from the cylinder. In this way, the cycle is completed to finish the filtering operation. Through this filtering method, slow feeding and filtering can be achieved, improving the filtering efficiency and quality. Moreover, through the cyclic flipping method, the sand and gravel can be turned over, preventing impurities from blocking the filter net and affecting the filtering efficiency and quality. At the same time, during the turning process, the sand and gravel can collide, resulting in good separation of impurities from the sand and gravel and preventing caking.

[0026] 2. During the feeding and flipping process, under the action of the falling and flipping of the sand and gravel, the distribution plate can be vibrated in cooperation with a spring, and the sand and gravel can be slapped, which can not only promote the separation of the sand and gravel from the impurities, but also make the sand and gravel scatter more dispersedly, further improving the filtering quality.

[0027] 3. During operation, when one of the sector cylinders disengages from the first half-ring seat and moves to a specified position, an electric telescopic rod drives the feeding head to move, so that the feeding head enters the discharge pipe, thus realizing the feeding operation of the sector cylinder. Moreover, during feeding, under the action of the through groove, the feeding head can move along with the sector cylinder, so as not to affect the normal rotation and filtering operation, achieving the effect of feeding and screening simultaneously, greatly ensuring the working efficiency.

[0028] 4. When there is no feeding, under the action of the first elastic component, the sealing plug is inserted into the communication port to block the communication port, preventing the sand and gravel from flowing out of the discharge head and preventing the sand and gravel from spilling outside. During feeding, the discharge head is connected to the discharge pipe, and under the action of the discharge pipe, the sealing plug is pushed open, thus realizing the connection between the discharge pipe and the discharge head and achieving normal feeding operation. This structure is simple and convenient, not only having a low failure rate, but also being fully automated and highly practical.

[0029] 5. During feeding, the discharging head enters the discharging pipe and squeezes the lifting rod, causing the ejector rod to move. As a result, while the first sealing plate disengages from the discharging pipe, the second sealing plate seals the discharging opening. Then, the ejector rod squeezes the plug, pushing the plug open, thus achieving the connection between the discharging pipe and the discharging head. While realizing normal feeding operation, it prevents unfiltered sand and gravel from being directly discharged from the discharging opening. After the feeding is completed, under the action of the second elastic component, the first sealing plate seals the discharging pipe, and at the same time, the discharging opening is opened, enabling the sand and gravel to enter the discharging pipe through the discharging opening after filtration and then being discharged into the aggregate tank from the other end of the discharging pipe, facilitating the collection of the filtered sand and gravel. This structure realizes the free switching between the feeding and filtering modes, providing great convenience for the flipping and filtering operation. Moreover, the structure is simple, highly compact, does not require the cooperation of electrical components, and has a low failure rate.

[0030] 6. The driving motor can drive the first bevel gear to rotate. The first bevel gear drives the threaded rod to rotate through the second bevel gear, thereby causing the threaded rod to drive the adjusting plate to move and changing the degree to which the adjusting plate extends out of the support seat, thus realizing the change of the falling speed of the sand and gravel flow and meeting different filtering requirements. At the same time, during filtration, the driving motor can also rotate forward and backward cyclically, causing the adjusting plate to move reciprocally, thereby improving the filtering effect. The two working modes can be selected according to requirements. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0040] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0041] As Figures 1-8 shown, the rapid sand and gravel filtering and impurity removing device for the zoo construction project includes the first support 1 and the second support 3. A storage bin 2 is fixed on the first support 1, and a mounting frame 4 is fixed on the second support 3. A rotating motor is fixed on the mounting frame 4. The output shaft end of the rotating motor is fixed with a rotating shaft, and the rotating shaft is fixedly connected with the mounting frame 4. A filter cylinder 5 is fixed on the rotating shaft. The filter cylinder 5 is composed of a cylinder 9 and two sector cylinders 10. The two sector cylinders 10 are respectively fixed at both ends of the cylinder 9. A filter net 11 is fixed at one end of the sector cylinder 10 away from the cylinder 9. A discharge pipe 12 is fixed at the end of the sector cylinder 10 away from the cylinder 9. The end of the discharge pipe 12 located inside the sector cylinder 10 passes through the filter net 11. A discharge port 29 is opened on the side of the discharge pipe 12. The discharge port 29 is located inside the sector cylinder 10 and is close to the end of the sector cylinder 10 away from the cylinder 9. A first half-ring seat 7 is fixed on the second support 3. An aggregate chute 8 is opened on the upper side of the first half-ring seat 7. The other end of the discharge pipe 12 is located in the aggregate chute 8. A discharge pipe 6 is fixed at the lower end of the first half-ring seat 7. A switching component is arranged inside the discharge pipe 12, and a feeding component is arranged at the lower end of the storage bin 2.

[0042] The sand and gravel is stored in the storage bucket 2. During operation, the sand and gravel is sent into the filter cylinder 5 through the feeding assembly. The rotating motor drives the filter cylinder 5 to rotate. During the rotation, the discharge pipe 12 of the sector cylinder 10 below is located in the aggregate chute 8. The sand and gravel slowly falls from the upper sector cylinder 10 through the cylinder 9 into the lower sector cylinder 10. After being screened by the filter net 11, it falls into the aggregate chute 8 through the discharge pipe 12, is collected uniformly and discharged through the discharge pipe 6. When the rotation exceeds 90°, the working modes of the two sector cylinders 10 are exchanged, so that the sand and gravel flows back from the cylinder 9. In this way, the filtration operation is completed. Through this filtration method, slow feeding filtration can be realized, the filtration efficiency and quality can be improved. And through the cyclic flipping method, the sand and gravel can be turned over, preventing debris from blocking the filter net 11 and affecting the filtration efficiency and quality. At the same time, during the turning process, the sand and gravel can collide, making the separation effect of impurities and sand and gravel good, and preventing caking.

[0043] A support seat 13 is slidably connected inside the cylinder 9. A support rod 14 is fixed on the support seat 13. The other end of the support rod 14 is fixed with a distribution plate 15. A number of distribution holes 16 are provided on the distribution plate 15.

[0044] With the above structure, when the sand and gravel is fed, through the cooperation of the distribution plate 15 and the distribution holes 16, the sand and gravel can be scattered and sprinkled on the filter net 11, preventing the sand and gravel from accumulating in the middle of the filter net 11 and affecting the filtration effect.

[0045] A chute 17 is provided inside the cylinder 9. A slider 18 is slidably connected inside the chute 17. The slider 18 is fixedly connected with the support seat 13 through a connecting rod 19. Springs 20 are fixed at both the upper and lower ends of the slider 18. The other end of the spring 20 is fixedly connected with the chute 17. Sealing plates 22 are fixed on both sides of the upper side of the slider 18. A U-shaped sealing frame 21 is slidably connected to the sealing plate 22. The U-shaped sealing frame 21 is fixedly connected with the chute 17. The front and rear sides of the U-shaped sealing frame 21 and the sealing plate 22 are in contact with the chute 17.

[0046] With the above structure, during the feeding and flipping process, under the action of the falling and flipping of the sand and gravel, the distribution plate 15 can be vibrated in cooperation with the spring 20, and the sand and gravel can be slapped, which can not only promote the separation of the sand and gravel from the debris, but also make the sand and gravel scatter more dispersedly, further improving the filtration quality.

[0047] The feeding assembly includes a feeding pipe 50, which is fixedly connected to the lower end of the storage pipe. A second semi-ring seat 30 is fixed to the lower end of the feeding pipe 50. A feeding cavity 40 is formed inside the second semi-ring seat 30. A through groove is formed on the lower side of the feeding cavity 40. A feeding seat 31 that is slidably connected to the feeding cavity 40 is slidably connected inside the through groove. An electric telescopic rod 32 is fixed to the lower side of the feeding seat 31. A feeding head 35 is fixed to the lower end of the electric telescopic rod 32. A telescopic pipe 34 is fixed to the feeding head 35. A transmission pipe 33 is slidably connected to the telescopic pipe 34. The transmission pipe 33 is fixedly connected to the feeding seat 31. A shielding assembly is arranged between the feeding seat 31 and the through groove.

[0048] With the above structure, during operation, when one of the fan-shaped cylinders 10 disengages from the first semi-ring seat 7 and moves to a specified position, the electric telescopic rod 32 drives the feeding head 35 to move, so that the feeding head 35 enters the discharge pipe 12, thereby realizing the feeding operation for the fan-shaped cylinder 10. And during feeding, under the action of the through groove, the feeding head 35 can move along with the fan-shaped cylinder 10, thus not affecting the normal rotary filtration operation, achieving the effect of feeding and screening simultaneously, and greatly ensuring the working efficiency.

[0049] The shielding assembly includes an arc-shaped plate 41. Arc-shaped guiding grooves 42 are formed on both the front and rear sides of the through groove. The ends of the arc-shaped guiding grooves 42 extend out of the second semi-ring seat 30. There are two arc-shaped plates 41, which are respectively fixed to the left and right sides of the feeding seat 31. The arc-shaped plates 41 are slidably connected to the arc-shaped guiding grooves 42.

[0050] With the above structure, while ensuring the sliding feeding of the feeding seat 31 in the through groove, the sealing property of the through groove can be ensured, preventing sand and gravel from falling from the through groove and ensuring the normal progress of the work.

[0051] A feeding cavity 40 is formed inside the feeding head 35. A communication port 36 is formed at the lower end of the feeding cavity 40. A first elastic component 39 is fixed inside the feeding cavity 40. An L-shaped rod 38 is fixed to the first elastic component 39. The other end of the L-shaped rod 38 is fixed with a sealing plug 37, and the sealing plug 37 is inserted into the communication port 36.

[0052] With the above structure, when there is no feeding, under the action of the first elastic component 39, the sealing plug 37 is inserted into the communication port 36 to block the communication port 36, so that sand and gravel will not flow out of the discharge head, preventing sand and gravel from spilling outside. During feeding, when the discharge head is connected to the discharge pipe 12, under the action of the discharge pipe 12, the sealing plug 37 is pushed open, thereby realizing the connection between the discharge pipe 12 and the discharge head and achieving normal feeding operation. This structure is simple and convenient, not only has a low failure rate, but also is fully automated throughout the process and has strong practicability.

[0053] The switching component includes a second elastic component 23 fixed inside the discharge pipe 12. A lifting rod 24 is fixed on the second elastic component 23. A top rod 25 is fixed on the lifting rod 24. A first sealing plate 26 is fixed at the lower end of the top rod 25. A support rod 27 is fixed in the middle of the top rod 25. The other end of the support rod 27 is fixed with a second sealing plate 28.

[0054] With the above structure, during feeding, the discharge head enters the discharge pipe 12, squeezes the lifting rod 24, causing the top rod 25 to move. Thus, while the first sealing plate 26 disengages from the discharge pipe 12, the second sealing plate 28 seals the discharge port 29. Then, the top rod 25 squeezes the plug 37 and pushes the plug 37 open, thus realizing the connection between the discharge pipe 12 and the discharge head. While realizing normal feeding operation, it prevents unfiltered sand and gravel from being directly discharged from the discharge port 29. After the feeding is completed, under the action of the second elastic component 23, the first sealing plate 26 seals the discharge pipe 12, and at the same time opens the discharge port 29, enabling the sand and gravel to enter the discharge pipe 12 through the discharge port 29 after filtration, and then being discharged into the aggregate tank 8 from the other end of the discharge pipe 12, facilitating the collection of the filtered sand and gravel. This structure realizes the free switching between the feeding and filtering modes, provides great convenience for the flipping and filtering operation, and has a simple structure, high compactness, does not require electrical components to cooperate, and has a low failure rate.

[0055] A driving cavity 43 is opened inside the support seat 13. A driving component is arranged inside the driving cavity 43. The periphery of the driving cavity 43 is slidably connected with an adjusting plate 44. The other end of the adjusting plate 44 extends out of the support seat 13. The adjusting plate 44 is connected with the driving component.

[0056] The driving component includes a driving motor fixed inside the driving cavity 43. A first bevel gear 45 is fixed at the output shaft end of the driving motor. Four bearing seats 49 are fixed inside the driving cavity 43. A second bevel gear 48 is rotatably connected to the bearing seat 49. The first bevel gear 45 meshes with the second bevel gear 48. A threaded rod 46 is fixedly connected to the second bevel gear 48 through a transmission shaft. A threaded groove 47 is opened inside the adjusting plate 44. The threaded rod 46 is threadedly connected with the threaded groove 47.

[0057] With the above structure, the driving motor can drive the first bevel gear 45 to rotate. The first bevel gear 45 drives the threaded rod 46 to rotate through the second bevel gear 48, so that the threaded rod 46 drives the adjusting plate 44 to move, changing the degree to which the adjusting plate 44 extends out of the support seat 13, thus realizing the change of the falling speed of the sand and gravel flow, meeting different filtering requirements. At the same time, during filtration, the driving motor can also rotate forward and reverse cyclically, causing the adjusting plate 44 to move back and forth, thereby improving the filtering effect. The two working modes can be selected according to requirements.

[0058] Working principle of the present invention: The sand and gravel are stored in the storage barrel 2. During operation, the electric telescopic rod 32 drives the feeding head 35 to move, so that the feeding head 35 enters the discharge pipe 12, squeezes the lifting rod 24, and makes the ejector rod 25 move. As a result, while the first sealing plate 26 disengages from the discharge pipe 12, the second sealing plate 28 seals the discharge port 29. Then, the ejector rod 25 squeezes the plug 37 and pushes the plug 37 open, thus realizing the connection between the discharge pipe 12 and the discharge head, achieving normal feeding operation, and preventing unfiltered sand and gravel from being directly discharged from the discharge port 29. The sand and gravel are sent into the filter cylinder 5 through the feeding assembly. At the same time, the rotating motor drives the filter cylinder 5 to rotate. During the rotation, the discharge pipe 12 of the lower sector cylinder 10 is located in the aggregate chute 8. Under the action of the second elastic component 23, the first sealing plate 26 seals the discharge pipe 12, and at the same time, the discharge port 29 is opened, so that the sand and gravel after filtration can enter the discharge pipe 12 through the discharge port 29, and then be discharged into the aggregate chute 8 from the other end of the discharge pipe 12. The sand and gravel slowly fall from the upper sector cylinder 10 through the cylinder 9 into the lower sector cylinder 10, and after being screened by the filter net 11, they fall into the aggregate chute 8 through the discharge pipe 12, are collected uniformly and discharged through the discharge pipe 6. During the feeding and flipping process, under the action of the falling and flipping of the sand and gravel, the distribution plate 15 can be vibrated in cooperation with the spring 20, and the sand and gravel can be slapped, which can not only promote the separation of the sand and gravel from the sundries, but also make the sand and gravel scatter more dispersedly, further improving the filtration quality. When the rotation exceeds 90°, the working modes of the two sector cylinders 10 are exchanged, so that the sand and gravel flow back from the cylinder 9. In this way, the filtration operation is completed. Through this filtration method, slow feeding and filtration can be realized, the filtration efficiency and quality can be improved, and through the cyclic flipping method, the sand and gravel can be turned over to prevent sundries from blocking the filter net 11 and affecting the filtration efficiency and quality. At the same time, during the flipping process, the sand and gravel can collide with each other, resulting in good separation effect between the impurities and the sand and gravel, and preventing the generation of caking. When the filtration requirements are different, the driving motor drives the first bevel gear 45 to rotate, and the first bevel gear 45 drives the threaded rod 46 to rotate through the second bevel gear 48, so that the threaded rod 46 drives the adjusting plate 44 to move, and the degree of the adjusting plate 44 extending out of the support seat 13 changes, thus realizing the change of the flowing and falling speed of the sand and gravel, meeting different filtration requirements. At the same time, during filtration, the driving motor can also rotate forward and backward cyclically, so that the adjusting plate 44 reciprocates, thereby improving the filtration effect. The two working modes can be selected according to the requirements.

[0059] In summary, through the arrangement of structures such as the filter cylinder 5, the first half-ring seat 7, and the second half-ring seat 30, the function of preventing sundries such as stones from blocking the filter net 11 while improving the filtration efficiency and quality is realized.
