Description

Technical Field

[0001] The present invention relates to the technical field of ditch dredging, and specifically to a ditch dredging device. Background Art

[0002] In municipal road facilities, as one of the important facilities of the urban drainage system, the drainage ditch is an important carrier for treating and discharging road surface sewage and rainwater. Due to various reasons, it often occurs that the drainage ditch is blocked and loses its dredging function, which has a very bad impact on the road surface conditions. Therefore, it is often necessary to dredge and maintain the drainage ditch.

[0003] The prior art also proposed a solution for ditch dredging. For example, a Chinese patent application with the publication number CN221480915U discloses a ditch dredging device, including a mounting plate. A limiting plate is fixedly connected to the surface of the mounting plate. A scraper is threadedly connected to the bottom of the limiting plate through a connecting plate. Through holes are arranged at equal intervals in a square matrix on the surface of the scraper. Arc-shaped plates are welded on both sides of the scraper. A circular plate is fixedly connected to one side of the limiting plate, and a rotating groove is arranged on the surface of the circular plate. For this ditch dredging device, through the setting of the connecting plate, the scraper and the cutting component, the servo motor is externally powered, its driving rod drives the rotating rod to rotate, and the cutting blade rotates accordingly. The cutting blade cuts the underwater foreign objects, and the scraper scrapes the silt at the bottom of the water, so as to achieve the purpose of facilitating personnel to clean the ditch.

[0004] Although the above technical solution cuts the underwater foreign objects through the cutting blade, there are still other problems in actual use. For example, there is a lot of silt in the ditch. After the silt is dug out, it is generally piled up on the roadside, or it is transported away by a truck for subsequent treatment. However, because the silt is not dehydrated, it will occupy a large space and is not conducive to subsequent treatment.

[0005] Therefore, it is necessary to provide a ditch dredging device to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the inventive concept of the present invention. Therefore, it may include information that does not constitute the prior art. Summary of the Invention

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A ditch dredging device includes a dredging vehicle. Four sets of moving wheels are installed around the lower part of the dredging vehicle. A fixed seat is installed on the upper end surface of the dredging vehicle. A deflection bracket is rotatably arranged on the outside of the fixed seat. A connecting bracket is rotatably arranged in front of the deflection bracket. A dredging frame is rotatably arranged on the lower end surface of the connecting bracket. The dredging frame is used to dig the silt in the ditch. A processing frame is installed on the side wall of the dredging vehicle. The processing frame is used to crush the dug silt. A centrifugal dehydration chamber is installed at the lower edge of the dredging vehicle.

[0008] Further, a rotating frame is rotatably arranged on the upper end surface of the dredging vehicle. The connecting bracket is connected to the side wall of the rotating frame through a plurality of cross bars. The deflection bracket is connected to the side wall of the rotating frame through a plurality of cross bars. During operation, the deflection bracket and the connecting bracket are driven to rotate by the rotating frame, which can conveniently adjust the depth of the dredging frame in the ditch and improve the treatment effect of the silt in the ditch.

[0009] Further, a rotating vertical shaft is rotatably arranged inside the processing frame. The end of the rotating vertical shaft is connected to the output end of an external motor. A plurality of crushing rods are fixedly installed on the outer peripheral surface of the rotating vertical shaft. The plurality of crushing rods are arranged in a circle on the outer peripheral surface of the rotating vertical shaft. The shape of the crushing rod is conical. A suction pipe is arranged at the bottom of the processing frame. The suction pipe is used to suck the crushed silt.

[0010] Further, a frame-shaped frame is fixedly installed below the dredging vehicle. Two sets of transmission shafts are rotatably arranged inside the frame-shaped frame. A transmission belt is jointly arranged on the outer peripheral surfaces of the two sets of transmission shafts. The transmission direction of the transmission belt is designed to correspond to the outlet end of the suction pipe. The ends of the two sets of transmission shafts are connected by a belt. The end of one of the transmission shafts is connected to the output end of an external motor. A centrifugal dehydration chamber is installed at the lower edge of the dredging vehicle. The opening of the centrifugal dehydration chamber is designed along the transmission direction of the transmission belt. During operation, the crushed silt will be sucked into the surface of the transmission belt through the suction pipe. The transmission shaft is controlled to rotate through an external controller, and the transmission shaft drives the transmission belt to operate. The transmission belt transports the relatively uniform silt into the centrifugal dehydration chamber. Through the dehydration process inside the centrifugal dehydration chamber, the uniform silt can be dehydrated, so as to facilitate the formation of mud cakes and subsequent use. The transmission belt is designed to facilitate the transportation of the crushed silt.

[0011] Further, a support plate is installed below the dredging vehicle. A plurality of separating rods are installed on the lower end surface of the support plate. The bottom end of each separating rod is in contact with the end surface of the transmission belt. The shape of the bottom end of the separating rod is conical. The plurality of separating rods are arranged at equal distances above the transmission belt.

[0012] Further, a fixing frame is installed below the dredging vehicle. A rotating horizontal shaft is rotatably arranged inside the fixing frame. A plurality of connecting rods are fixedly installed on the outer peripheral surface of the rotating horizontal shaft. Each group of connecting rods and the separating rods are designed at intervals. A scraping rod is installed at the bottom end of the connecting rod. The shape of the scraping rod is hook-shaped. During operation, when the conveyor belt conveys the silt and part of the plastic bags are blocked on one side of the separating rod, at the same time, by controlling the rotation of the rotating horizontal shaft, the rotating horizontal shaft drives the connecting rods and the scraping rods outside it to rotate clockwise. Since the connecting rods, the scraping rods and the separating rods are designed at intervals, the hook-shaped scraping rod will hook part of the blocked plastic bags during the clockwise rotation, so as to facilitate the subsequent automatic collection of the hooked plastic bags.

[0013] Further, a collection box is installed below the dredging vehicle. During the process of the rotating horizontal shaft driving the scraping rod to rotate, the end face of the scraping rod will contact the side wall of the collection box. The scraping rod is rotatably arranged at the bottom of the connecting rod, and a torsion spring is arranged at the position where the scraping rod is rotatably connected to the connecting rod.

[0014] Further, a limiting frame is arranged on the side of the dredging vehicle. The support plate is slidably arranged inside the limiting frame. A dispersing unit is arranged inside the limiting frame. The dispersing unit is used for dispersing the silt on one side of the separating rod. During operation, when the separating rod gradually separates the silt, if there is still some silt that is not completely broken, the side of the separating rod will be subjected to greater force. And since the support plate is slidably arranged inside the limiting frame, the dispersing unit inside the limiting frame will be triggered, so that the dispersing unit will further disperse the silt on one side of the separating rod, which is convenient for the treatment of the silt.

[0015] Further, the dispersing unit includes a sliding rod slidably arranged inside the limiting frame. The end of the sliding rod is connected to the side wall of the support plate. A limiting arc block is installed on the outer side of the sliding rod. A limiting groove is arranged inside the limiting frame. The shapes of the limiting arc block and the limiting groove are adapted to each other. A contact point one is installed at the end of the sliding rod. A contact point two is installed on the inner wall of the limiting frame. Two crushing disks are arranged below the dredging vehicle. The crushing disks are controlled by an external hydraulic system. Conical rods are arranged on the surfaces of the crushing disks.

[0016] Further, a groove adapted to the sliding rod is arranged inside the limiting frame, and a limiting spring is installed inside the groove. One end of the limiting spring is connected to the side wall of the sliding rod. During operation, when the crushing disks crush the silt, at this time, the rotating horizontal shaft will stop running under the control of an external controller. After the crushing disks finish crushing the silt, the external controller will first control the crushing disks to return to the initial position, and then control the rotating horizontal shaft to run again. Therefore, the further crushed silt is conveyed along between the separating rods, thus improving the silt treatment efficiency.

[0017] The beneficial effects of the present invention are as follows: For a ditch dredging device provided by the present invention, during the process of driving the connecting rod and the scraping rod to rotate clockwise by rotating the horizontal shaft, that is, when the scraping rod rotates to one side of the collection frame, since the scraping rod is rotatably arranged at the bottom of the connecting rod, when the scraping rod contacts the collection frame, under the limit of the collection frame, the scraping rod will rotate by a certain amplitude. Then, as the scraping rod continues to move, the plastic bags on the surface of the scraping rod will slowly fall into the interior of the collection frame.

[0018] By controlling the rotation of the transmission shaft through an external controller, the transmission shaft drives the conveyor belt to operate. The conveyor belt transports the relatively uniform silt to the inside of the centrifugal dehydration chamber. Through the dehydration process inside the centrifugal dehydration chamber, the uniform silt can be dehydrated, thus facilitating the formation of mud cakes for subsequent use. The conveyor belt is designed to facilitate the transportation of the crushed silt.

[0019] As the force on the side of the separation rod increases, the separation rod and the support plate above it are subjected to increased force. Therefore, the support plate will drive the sliding rod to slide inside the limit frame. When the force on the side of the separation rod is greater than the clamping force between the limit arc block and the limit groove, the sliding rod will drive the contact point one to contact the contact point two, thereby turning on the external circuit. The external controller will control the external hydraulic system to drive the crushing disc to move, that is, the crushing disc will move towards the side of the accumulated silt. Then, when the conical rod on the surface of the crushing disc contacts the silt, it can further crush some of the silt that has not passed through the separation rod, thus facilitating the transportation of the silt.

[0020] In addition to the purposes, features, and advantages described above, the present invention has other purposes, features, and advantages. The following will refer to the drawings for a further detailed description of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0023] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0024] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] As Figures 1 to 10 shown, the present invention provides a ditch dredging device, including a dredging vehicle 1. Four groups of moving wheels 2 are installed around the lower part of the dredging vehicle 1. A fixed seat 3 is installed on the upper end surface of the dredging vehicle 1. A deflection bracket 301 is rotatably arranged outside the fixed seat 3. A connecting bracket 4 is rotatably arranged in front of the deflection bracket 301. A dredging frame 5 is rotatably arranged on the lower end surface of the connecting bracket 4. The dredging frame 5 is used to dig the silt in the ditch. A treatment frame 6 is installed on the side wall of the dredging vehicle 1. The treatment frame 6 is used to crush the dug silt. A centrifugal dehydration chamber 14 is installed at the lower edge of the dredging vehicle 1; During operation, the external controller is used to control the moving wheels 2 to drive the entire dredging vehicle 1 to move to a suitable position in the water channel. Then, the external hydraulic drive system is used to control the deflection bracket 301, the connecting bracket 4, and the dredging frame 5 to move closer to the inside of the water channel, so that the dredging frame 5 can dig the silt inside the water channel. After that, the dug silt will enter the treatment frame 6, and the treatment frame 6 will perform subsequent crushing treatment on the silt. By continuously treating the silt in the water channel in this way, it is convenient for the subsequent use of the water channel. Moreover, under the action of the connecting bracket 4 and the deflection bracket 301, the flexibility of the dredging frame 5 can be improved, and further, the dredging of water channels with various depths can be carried out. After that, the crushed silt will be transported to the centrifugal dehydration chamber 14 for dehydration treatment of the silt, which is convenient for the subsequent continuous treatment of the silt, such as making mud cakes for use, etc.

[0026] It should be noted that when the small pieces of crushed silt enter the centrifugal dehydration chamber 14, it is convenient for the centrifugal dehydration of the silt.

[0027] It should be noted that the deflection bracket 301, the connecting bracket 4, and the dredging frame 5 in the embodiments of the present invention are all controlled by an external hydraulic drive system, and the control method and the digging method are similar to the principle of an excavator in the prior art, and will not be elaborated in the embodiments of the present invention.

[0028] A rotating frame 7 is rotatably arranged on the upper end surface of the dredging vehicle 1. The connecting bracket 4 is connected to the side wall of the rotating frame 7 through a plurality of cross bars, and the deflection bracket 301 is connected to the side wall of the rotating frame 7 through a plurality of cross bars. During operation, by driving the deflection bracket 301 and the connecting bracket 4 to rotate through the rotating frame 7, it is convenient to adjust the depth of the dredging frame 5 in the water channel and improve the treatment effect of the silt in the water channel.

[0029] A rotating vertical shaft 8 is rotatably arranged inside the treatment frame 6. The end of the rotating vertical shaft 8 is connected to the output end of an external motor. A plurality of groups of crushing rods 9 are fixedly installed on the outer peripheral surface of the rotating vertical shaft 8. The plurality of groups of crushing rods 9 are arranged in a circle on the outer peripheral surface of the rotating vertical shaft 8. The shape of the crushing rod 9 is conical. A suction pipe 10 is arranged at the bottom of the treatment frame 6, and the suction pipe 10 is used to suck the crushed silt. During operation, the silt dug out by the dredging frame 5 will be poured into the inside of the treatment frame 6 under its own rotation. Then, the external controller drives the rotating vertical shaft 8 to rotate, and the rotating vertical shaft 8 drives the crushing rods 9 outside it to rotate. The crushing rods 9 will crush the silt blocks with larger diameters. After that, the crushed silt is extracted to the subsequent treatment steps through the suction pipe 10. The crushed silt has a uniform particle size and strong fluidity, which is convenient for the subsequent centrifugal dehydration of the silt and is also conducive to separating from other substances such as plastics and other impurities in the silt.

[0030] A frame-shaped rack 11 is fixedly installed below the dredging vehicle 1. Two transmission shafts 12 are rotatably arranged inside the frame-shaped rack 11. A transmission belt 13 is jointly arranged on the outer peripheral surfaces of the two transmission shafts 12. The transmission direction of the transmission belt 13 is designed corresponding to the outlet end of the suction pipe 10. The ends of the two transmission shafts 12 are connected by a belt. The end of one transmission shaft 12 is connected to the output end of an external motor. The opening of the centrifugal dehydration chamber 14 is designed along the transmission direction of the transmission belt 13. During operation, the crushed sludge will be sucked into the surface of the transmission belt 13 through the suction pipe 10. The transmission shaft 12 is controlled to rotate through an external controller. The transmission shaft 12 drives the transmission belt 13 to operate. The transmission belt 13 conveys the relatively uniform sludge into the centrifugal dehydration chamber 14. Through the dehydration process inside the centrifugal dehydration chamber 14, the uniform sludge can be dehydrated, so as to facilitate the formation of mud cakes and subsequent use. The transmission belt 13 is designed to facilitate the conveyance of the crushed sludge.

[0031] A support plate 15 is installed below the dredging vehicle 1. Multiple separating rods 151 are installed on the lower end surface of the support plate 15. The bottom end of each group of separating rods 151 is in contact with the end surface of the transmission belt 13. The shape of the bottom end of the separating rod 151 is conical. The multiple separating rods 151 are designed at equal distances above the transmission belt 13. During operation, refer to the attached Figure 5 As shown, the bottom end of each group of separating rods 151 is in contact with the end surface of the transmission belt 13. When the transmission belt 13 conveys the crushed sludge, the sludge will pass through the separating rods 151. Under the limitation of the separating rods 151, on the one hand, it can not only block the plastic bags existing in the sludge to prevent the plastic bags from entering the subsequent centrifugal dehydration chamber 14, but also further separate the sludge, making the sludge more uniform during the transmission process, that is, it can sort out the sludge during the transmission process and facilitate subsequent centrifugal dehydration of it. It should be noted that the diameter of the blocked plastic bags is larger than the distance between two adjacent separating rods 151.

[0032] A fixed frame 16 is installed below the dredging vehicle 1. A rotating horizontal shaft 17 is rotatably arranged inside the fixed frame 16. Multiple connecting rods 18 are fixedly installed on the outer peripheral surface of the rotating horizontal shaft 17. Each group of connecting rods 18 and separating rods 151 are arranged at intervals. A scraping rod 19 is installed at the bottom end of the connecting rod 18. The shape of the scraping rod 19 is hook-shaped. During operation, during the transmission of the sludge by the transmission belt 13 and when some plastic bags are blocked on one side of the separating rods 151, at the same time, by controlling the rotation of the rotating horizontal shaft 17, the rotating horizontal shaft 17 drives the connecting rods 18 and the scraping rod 19 outside it to rotate clockwise. Since the connecting rods 18, the scraping rod 19 and the separating rods 151 are arranged at intervals, the hook-shaped scraping rod 19 will hook some of the blocked plastic bags during the clockwise rotation process, so as to facilitate the subsequent automatic collection of the hooked plastic bags.

[0033] A collection frame 20 is installed below the dredging vehicle 1. During the process of the rotating horizontal shaft 17 driving the scraping rod 19 to rotate, the end face of the scraping rod 19 will contact the side wall of the collection frame 20. The scraping rod 19 is rotatably arranged at the bottom of the connecting rod 18, and a torsion spring is arranged at the position where the scraping rod 19 is rotatably connected to the connecting rod 18. During operation, refer to the attached Figure 5 , Figure 6 and Figure 7 As shown, when the rotating horizontal shaft 17 drives the connecting rod 18 and the scraping rod 19 to rotate clockwise, that is, when the scraping rod 19 rotates to one side of the collection frame 20, since the scraping rod 19 is rotatably arranged at the bottom of the connecting rod 18, when the scraping rod 19 contacts the collection frame 20, under the limitation of the collection frame 20, the scraping rod 19 will rotate by a certain amplitude and rotate to the state as shown in the attached Figure 8 As shown. Then, as the scraping rod 19 continues to move, the plastic bags on the surface of the scraping rod 19 will slowly fall into the interior of the collection frame 20.

[0034] A limiting frame 21 is arranged on the side of the dredging vehicle 1. The support plate 15 is slidably arranged inside the limiting frame 21. A dispersion unit is arranged inside the limiting frame 21, and the dispersion unit is used to disperse the silt on one side of the separating rod 151. During operation, as the separating rod 151 gradually separates the silt, if there is still some silt that is not completely broken, the force on the side of the separating rod 151 will increase. And since the support plate 15 is slidably arranged inside the limiting frame 21, the dispersion unit inside the limiting frame 21 will be triggered, so that the dispersion unit will further disperse the silt on one side of the separating rod 151, which is convenient for the treatment of the silt.

[0035] The dispersion unit includes a sliding rod 22 slidably disposed inside the limit frame 21. The end of the sliding rod 22 is connected to the side wall of the support plate 15. A limit arc block 23 is installed outside the sliding rod 22. A limit groove 24 is provided inside the limit frame 21. The shapes of the limit arc block 23 and the limit groove 24 are adapted to each other. A first contact 25 is installed at the end of the sliding rod 22. A second contact 26 is installed on the inner wall of the limit frame 21. Two sets of crushing discs 27 are provided below the dredging vehicle 1. The crushing discs 27 are controlled by an external hydraulic system. The surface of the crushing discs 27 is provided with tapered rods. During operation, in the initial state, the limit arc block 23 is located inside the limit groove 24, and the first contact 25 and the second contact 26 do not contact. As the force on the side of the separating rod 151 increases, the separating rod 151 and the support plate 15 above it are subjected to greater force. Therefore, the support plate 15 will drive the sliding rod 22 to slide inside the limit frame 21. When the force on the side of the separating rod 151 is greater than the clamping force between the limit arc block 23 and the limit groove 24, the sliding rod 22 will drive the first contact 25 to contact the second contact 26, thereby turning on the external circuit. The external controller will control the external hydraulic system to drive the crushing discs 27 to move, that is, the crushing discs 27 will move towards the side of the accumulated sludge. After that, when the tapered rods on the surface of the crushing discs 27 contact the sludge, they can further crush some of the sludge that has not passed through the separating rod 151, thus facilitating the transmission of the sludge.

[0036] It should be noted that referring to the attached Figure 8 As shown, the crushing discs 27 are controlled by an external hydraulic cylinder, and the hydraulic cylinder is installed below the dredging vehicle 1. The telescopic end of the hydraulic cylinder contacts the end face of the crushing discs 27. It should also be noted that multiple sets of tapered rods are provided on the surface of the crushing discs 27.

[0037] A groove adapted to the sliding rod 22 is provided inside the limit frame 21, and a limit spring 28 is installed inside the groove. One end of the limit spring 28 is connected to the side wall of the sliding rod 22. During operation, when the crushing discs 27 crush the sludge, the rotating cross shaft 17 will stop rotating under the control of the external controller at this time. After the crushing discs 27 finish crushing the sludge, the external controller will first control the crushing discs 27 to return to the initial position, and then control the rotating cross shaft 17 to operate again. Therefore, the further crushed sludge is conveyed along between the separating rods 151, thereby improving the sludge treatment efficiency. It should be noted that when the sliding rod 22 drives the first contact 25 to contact the second contact 26, the sliding rod 22 will simultaneously squeeze the limit spring 28 on its side. After the sludge on one side of the separating rod 151 is processed, under the restoration of the elastic force of the limit spring 28, the sliding rod 22 will drive the support plate 15 and the separating rod 151 to return to the initial position, thus facilitating the subsequent continuous conveyance of the sludge. It should be noted that the restoration of the elastic force of the limit spring 28 can be sufficient to drive the support plate 15 and the separating rod 151 to return to the initial position.

[0038] Working principle: The external controller is used to control the moving wheels 2 to drive the entire dredging vehicle 1 to move to a suitable position of the water channel. Then, the external hydraulic drive system is used to control the deflection bracket 301, the connecting bracket 4, and the dredging frame 5 to move closer to the inside of the water channel, so that the dredging frame 5 can dig the silt inside the water channel. After that, the dug silt will enter the treatment frame 6, and the treatment frame 6 will perform subsequent crushing treatment on the silt. By continuously treating the silt in the water channel in this way, it is convenient for the subsequent use of the water channel. Moreover, under the action of the connecting bracket 4 and the deflection bracket 301, the flexibility of the dredging frame 5 can be improved, and further, the dredging of water channels with various depths can be carried out; the silt dug out by the dredging frame 5 will be poured into the inside of the treatment frame 6 under its own rotation. Then, the external controller drives the rotating vertical shaft 8 to rotate, and the rotating vertical shaft 8 drives the crushing rod 9 outside it to rotate. The crushing rod 9 will crush the larger silt blocks. Then, the crushed silt is extracted to the subsequent treatment steps through the suction pipe 10. The crushed silt has a uniform particle size and strong fluidity, which is convenient for subsequent centrifugal dehydration of the silt and is also conducive to separating from sundries such as plastics in the silt; Refer to the attached Figure 5 As shown, the bottom end of each separation rod 151 is in contact with the end face of the conveyor belt 13. When the conveyor belt 13 conveys the crushed silt, the silt will pass through the separation rod 151. Under the limitation of the separation rod 151, on the one hand, it can not only block the plastic bags existing in the silt to prevent the plastic bags from entering the subsequent centrifugal dehydration chamber 14, but also further separate the silt, making the silt more uniform during the conveying process, that is, it can sort out the silt during the conveying process and facilitate subsequent centrifugal dehydration; During the process of the conveyor belt 13 conveying the silt, and when some plastic bags are blocked on one side of the separation rod 151, at the same time, by controlling the rotation of the rotating horizontal shaft 17, the rotating horizontal shaft 17 drives the connecting rod 18 and the scraping rod 19 outside it to rotate clockwise. Since the connecting rod 18, the scraping rod 19, and the separation rod 151 are arranged at intervals, the hook-shaped scraping rod 19 will hook some of the blocked plastic bags during the clockwise rotation process, so as to facilitate the subsequent automatic collection of the hooked plastic bags; Refer to the attached Figure 5 、 Figure 6 and Figure 7 As shown, when the rotating horizontal shaft 17 drives the connecting rod 18 and the scraping rod 19 to rotate clockwise, that is, when the scraping rod 19 rotates to one side of the collection box 20, since the scraping rod 19 is rotatably arranged at the bottom of the connecting rod 18, when the scraping rod 19 contacts the collection box 20, under the limitation of the collection box 20, the scraping rod 19 will rotate by a certain amplitude and rotate to the position as shown in the attached Figure 8 As shown, and then under the continuous movement of the scraping rod 19, the plastic bags on the surface of the scraping rod 19 will slowly fall into the inside of the collection box 20; In the initial state, the limiting arc block 23 is located inside the limiting groove 24, and the first contact 25 and the second contact 26 are not in contact. As the force on the side of the separating rod 151 increases, the separating rod 151 and the supporting plate 15 above it are subjected to greater force. Therefore, the supporting plate 15 will drive the sliding rod 22 to slide inside the limiting frame 21. When the force on the side of the separating rod 151 is greater than the clamping force between the limiting arc block 23 and the limiting groove 24, the sliding rod 22 will drive the first contact 25 to contact the second contact 26, thereby turning on the external circuit. The external controller will control the external hydraulic system to drive the crushing disc 27 to move, that is, the crushing disc 27 will move towards the side where the silt accumulates. After that, when the conical rod on the surface of the crushing disc 27 contacts the silt, it can further crush some of the silt that has not passed through the separating rod 151, thus facilitating the transmission of the silt. When the crushing disc 27 crushes the silt, at this time, the rotating cross shaft 17 will stop operating under the control of the external controller. After the crushing disc 27 finishes crushing the silt, the external controller will first control the crushing disc 27 to return to the initial position, and then control the rotating cross shaft 17 to operate again. Therefore, the further crushed silt is conveyed along between the separating rods 151, thus improving the silt treatment efficiency.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
