DETAILED DESCRIPTION

[0029] See also Figure 1-Figure 10 In an embodiment of the present invention, an automatic silt removal device includes a shell 1. Preferably, collecting plates 2 are fixedly arranged on both sides of one end of the shell 1. The collecting plates 2 are in a structure that is open to both sides of the shell 1. In this way, when the silt removal device is silting, more sludge can enter the shell 1. A filter plate 3 is arranged between the two groups of collecting plates 2. The filter plate 3 is arranged in an inclined manner, that is, the end of the filter plate 3 away from the shell 1 is flush with the bottom of the collecting plate 2, and the end of the filter plate 3 close to the shell 1 is higher than the end away from the shell 1. In this way, when the silt moves toward the shell 1 through the action of the collecting plate 2, the impurities in the silt will be separated through the filter plate 3. A silt extraction pipe 7 for extracting and cleaning the silt is arranged at the bottom of the shell 1. A collecting component is arranged above the silt extraction pipe 7. The end of the collecting component close to the filter plate 3 is flush with the filter plate 3. The collecting component actively collects the impurities separated from the filter plate 3. Tracks are arranged on both sides of the shell 1. The arrangement of the tracks allows the overall device to have a mobile function, thereby making it more convenient to clean the silt.

[0030] A bottom plate is arranged between the bottom of the filter plate 3 and the bottom of the outer shell 1, and the bottom plate and the filter plate 3 are arranged at an acute angle, so that when in use, the bottom plate can prevent some impurities from entering the silt extraction pipe 7 through the gap between the outer shell 1 and the filter plate 3. Between the silt extraction pipe 7 and the filter plate 3 is a mud inlet 19 for the silt passing through the filter plate 3 to move to the silt extraction pipe 7. A driving assembly is arranged at one end of the outer shell 1 away from the filter plate 3, and the driving assembly can drive the silt extraction pipe 7 to extract and clean the silt, and drive the crawler to rotate to realize the movement function of the device. The specific related structure and working principle of the driving assembly are all existing technologies, which will not be described in detail here.

[0031] During specific use, when sludge cleaning is required, the device is moved to a predetermined position, and then the driving assembly drives the crawler to rotate and drives the silt extraction pipe 7 to extract the sludge. The moving device will gather part of the sludge on both sides of the shell 1 to the filter plate 3 through the collecting plate 2. Then the sludge passes through the separation effect of the filter plate 3, leaving the impurities in the sludge on the filter plate 3, and the sludge passing through the filter plate 3 will move to the silt extraction pipe 7 and be cleaned. In this way, the silt extraction pipe 7 will not be blocked when cleaning the sludge, and the collecting assembly can collect the impurities on the filter plate 3, avoiding excessive accumulation of impurities on the filter plate 3, resulting in a decrease in the flow of sludge through the filter plate 3, resulting in a decrease in the efficiency of the silt extraction pipe 7 in cleaning the sludge.

[0032] See also Figure 1 , Figure 3-Figure 5 Preferably, the collecting assembly includes a first rotating shaft 11; the first rotating shaft 11 is rotatably arranged in the middle of one end of the housing 1 close to the filter plate 3, and the first rotating shaft 11 is slidably fitted with the top end of the filter plate 3, and a separation rod 5 is arranged on the first rotating shaft 11, and the separation rod 5 is first arranged in a circular array on the first rotating shaft 11 with the center of the first rotating shaft 11, and then arranged in a horizontal array on the first rotating shaft 11 along the axial direction of the first rotating shaft 11, and a through groove 4 cooperating with the separation rod 5 is arranged on the side wall of one end of the filter plate 3 close to the housing 1, and one end of the first rotating shaft 11 passes through the side wall of the housing 1 and is fixedly connected to a transmission disk 21, and the transmission disk 21 is connected to the driving assembly through a belt, so that When in use, after impurities are separated from the sludge on the filter plate 3, the impurities will move to the through groove 4 while the sludge and the outer shell 1 are moving. At this time, the first rotating shaft 11 is driven by the driving component to rotate clockwise. The clockwise rotating first rotating shaft 11 drives the separation rod 5 to rotate clockwise. The rotating separation rod 5 will pass through the through groove 4 and wrap the impurities on the through groove 4 into the collecting component in the outer shell 1, thereby collecting the impurities, avoiding the accumulation of impurities on the filter plate 3, resulting in the deterioration of the separation effect of the filter plate 3 on the sludge, and avoiding the impurities returning to the sludge again, resulting in the need to separate the impurities when the sludge is cleaned next time.

[0033] Furthermore, preferably, fixed plates 9 are provided on both sides of the separation rod 5, and the fixed plates 9 are provided on one side of the outer shell 1 close to the first rotating shaft 11, and the fixed plates 9 are provided in parallel with the top of the inner wall of the outer shell 1, and the interval between two adjacent groups of fixed plates 9 is a matching opening 22, and the matching opening 22 is equal to the width of the through groove 4, and a connecting plate 10 is fixedly connected to the bottom of one end of the fixed plate 9 away from the first rotating shaft 11, and the connecting plate 10 is inclined, and the end of the connecting plate 10 away from the fixed plate 9 is toward the bottom of the outer shell 1, and the end of the connecting plate 10 away from the fixed plate 9 is fixedly connected to the collecting bin 6, the bottom of the collecting bin 6 is provided in parallel with the fixed plate 9, and the top of the collecting bin 6 is fixedly connected to the outer shell 1.

[0034] During specific use, when the first rotating shaft 11 rotates to drive the separation rod 5 to rotate, and the impurities on the filter plate 3 are cleaned by the separation rod 5, the separation rod 5 rotates so that the impurities on the filter plate 3 are brought to the multiple groups of fixed plates 9 by the separation rod 5, and then the impurities move to the connecting plate 10 on the fixed plate 9, and then under the action of the inclined connecting plate 10, the impurities move to the collecting bin 6, thereby completing the collection of the impurities, thereby avoiding the problem of impurities clogging the silt extraction pipe 7 and the problem that the impurities need to be cleaned again after entering the sludge, and the impurities collected in the collecting bin 6 can be processed centrally.

[0035] Furthermore, in order to prevent the impurities wrapped by the separation rod 5 from falling on the fixed plate 9 and not failing to move toward the connecting plate 10 and getting stuck with the separation rod 5, thereby causing damage to the separation rod 5, preferably, a conveying groove 20 is provided at the center of the fixed plate 9, and the conveying groove 20 extends to the connecting plate 10 at one end away from the fixed plate 9, and a conveyor belt 8 is rotatably provided in the conveying groove 20, and the top height of the conveyor belt 8 is higher than the top height of the fixed plate 9, and a second rotating shaft 13 is rotatably provided on the connecting plate 10, and the second rotating shaft 13 passes through one end of the conveying groove 20 away from the fixed plate 9, and one end of the conveyor belt 8 away from the fixed plate 9 is sleeved on the periphery of the second rotating shaft 13, and the second rotating shaft 13 is connected to the transmission disk 21 by a belt drive.

[0036] When in use, when the transmission disc 21 rotates clockwise, the transmission disc 21 drives the second rotating shaft 13 to rotate clockwise through the belt, and the clockwise rotation of the second rotating shaft 13 drives the conveyor belt 8 to rotate clockwise. The rotation of the conveyor belt 8 can transport the impurities wrapped by the separation rod 5 from the filter plate 3 to the collection bin 6, thereby avoiding the problem that the impurities fall on the fixed plate 9 and cannot move, causing the separation rod 5 to get stuck. It should be noted that when the separation rod 5 rotates clockwise to the through groove 4, due to the continued rotation of the separation rod 5, the impurities on the filter plate 3 will move to the through groove 4 under the push of the silt, and when the separation rod 5 rotates through the through groove 4, the filter plate 3, and then a group of separation rods 5 crossing the through slot 4 rotates to the top position of the first rotating shaft 11. During this process, the impurities picked up by the separation rods 5 will gradually move toward the first rotating shaft 11 on the separation rods 5 and fit with the first rotating shaft 11. When a group of separation rods 5 continues to rotate toward the direction of the fixed plate 9, the impurities will first contact the conveyor belt 8 on the fixed plate 9 because the impurities are close to the first rotating shaft 11. At this time, the conveyor belt 8 is in a rotating state, so the impurities will move toward the collecting bin 6 under the action of the conveyor belt 8, so when a group of separation rods 5 moves between the two groups of fixed plates 9, the impurities will first be transported to the collecting bin 6.

[0037] See also Figure 6 Preferably, protrusions 14 are fixedly provided on the surface of the conveyor belt 8, and a plurality of protrusions 14 are arranged in an array on the conveyor belt 8. When in use, when impurities come into contact with the conveyor belt 8, the impurities can be better driven by the rotation of the conveyor belt 8 through the action of the protrusions 14.

[0038] See also Figure 1 , Figure 7-10 Preferably, the first rotating shaft 11 is a hollow structure, a fixed shaft 12 is arranged in the center of the first rotating shaft 11, one end of the fixed shaft 12 is fixedly connected to the side wall of the shell 1, and one end of the separation rod 5 extending into the first rotating shaft 11 is fixedly connected to the first bevel gear 15, and a second bevel gear 16 is arranged on the fixed shaft 12 and is transmission-connected to the first bevel gear 15. The number of the second bevel gears 16 corresponds to the number of the separation rods 5 arranged in a horizontal array, and a group of second bevel gears 16 corresponds to the multiple groups of separation rods 5 arranged in a circular array on the first rotating shaft 11, so that the multiple groups of first bevel gears 15 are transmission-engaged with the group of second bevel gears 16, and the multiple groups of second bevel gears 16 are symmetrically arranged one by one along the center of the first rotating shaft 11.

[0039] During specific use, when the first rotating shaft 11 rotates, the fixed shaft 12 is in a fixed state, and the first bevel gear 15 and the second bevel gear 16 are in transmission meshing engagement, so that when the first rotating shaft 11 drives the separating rod 5 to rotate, the first bevel gear 15 will rotate around the fixed shaft 12, and then under the action of the second bevel gear 16, the first bevel gear 15 will rotate, and the rotation of the first bevel gear 15 will cause the separating rod 5 to rotate, and since the multiple groups of second bevel gears 16 are symmetrically arranged along the center, the multiple groups of separating rods 5 arranged horizontally are divided into two halves along the center, and the separating rods 5 of the two halves rotate in opposite directions, so that after the baffle separating rod 5 contacts the impurities on the filter plate 3, the impurities will be moved to the center position of the first rotating shaft 11 under the rotation of the two halves of the separating rod 5, thereby avoiding the impurities from contacting the side of the outer shell 1, causing the impurities to accumulate on the collecting plate 2 or the side wall of the outer shell 1.

[0040] Furthermore, preferably, a plurality of groups of mounting grooves 18 are arranged in an array on the separation rod 5, and the mounting grooves 18 are arranged in a staggered manner on the separation rod 5. A breaking rod 17 is elastically connected to the mounting groove 18 through a spring, and the breaking rod 17 is arranged in a diamond structure. In the initial state, the breaking rod 17 is in a state of being contracted in the mounting groove 18 under the action of the corresponding spring. When the separation rod 5 rotates, the breaking rod 17 extends out of the mounting groove 18 under the action of the centrifugal force generated by the rotation of the separation rod 5, and the width of the through groove 4 is sufficient for the breaking rod 17 to pass through when it extends out of the mounting groove 18.

[0041] During specific use, when the separation rod 5 rotates, the breaking rod 17 extends out of the installation groove 18. In this way, when the separation rod 5 rotates, the separation rod 5 rotates and drives the breaking rod 17 to rotate. The rotation of the breaking rod 17 can stir and break up the sludge on the filter plate 3 and the sludge that passes through the filter plate 3 but does not enter the silt extraction pipe 7, thereby avoiding the accumulation of large sludge lumps on the filter plate 3, which causes the filter plate 3 to be blocked by sludge.
