[0002] Cement poles are also called cement electric poles. They are columnar structures made mainly of cement, sand, and steel bars. They are mainly used to support and erect power lines and communication lines, provide sufficient safety height for the wires, and ensure that the lines maintain a safe distance from ground objects, pedestrians, and vehicles. In terms of power transmission, they can carry high-voltage, medium-voltage, and low-voltage wires to ensure that power is smoothly transmitted from power stations to various power consumption areas. In the field of communications, they are used to support communication lines such as telephone lines and optical fibers, providing physical support for the transmission of information.

[0003] After the sand and gravel are crushed, they need to be screened to screen out the gravel that does not meet the discharge standards. However, after a long period of screening, the gravel that does not meet the discharge standards will gather on the screen plate for a long time, thereby interfering with the crushing and screening work. Summary of the invention

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve the technical problems is: a sand and gravel crushing device for cement pole production and manufacturing according to the present invention comprises: A crushing component, which is used to crush sand and gravel required for cement pole production, a screening component is fixedly connected to the bottom of the crushing component, and a water storage component is fixedly connected to the bottom of the screening component; The crushing component comprises a crushing box, a feed port is fixedly connected to the top of the crushing box, a crushing roller is rotatably connected to the inner side of the crushing box, a first motor is fixedly connected to the side of the crushing box, an output end of the first motor is fixedly connected to one end of the crushing roller, and a receiving mechanism is fixedly connected to both sides of the crushing box; sand and gravel are put into the crushing box through the feed port, and the first motor is turned on, and the crushing roller is driven to rotate in the crushing box through the output end of the first motor, so that the sand and gravel are crushed, and the crushed sand and gravel are screened through the screening component, so that the sand and gravel that do not meet the crushing standard are screened out, and when the addition of sand and gravel to the crushing box is stopped, the sand and gravel remaining on the screening component is transported into the crushing box through the receiving mechanism for secondary crushing; The material collecting mechanism comprises a material collecting trough, which is symmetrically arranged on both sides of the crushing box, a material collecting shell is fixedly connected to the inner side of the material collecting trough, and an air pump is fixedly connected to the side of the material collecting shell; when the screening component is finished, after the sand and gravel that do not meet the discharge standard are screened out on the screening plate, air pumps are symmetrically arranged on both sides of the crushing box close to the feed trough, the air pump on one side works for suction, and the air pump on the other side works for exhaustion, and the air pumps on both sides work at the same time, and the generated airflow can form a balanced pushing force on the feed trough, and the airflows on both sides can work in coordination to push the remaining sand and gravel from various positions of the screening plate toward the direction of the feed trough, thereby entering the feed trough, ensuring that the sand and gravel on the entire screening plate can be effectively cleaned and recycled. By turning on the air pump and aiming the air outlet of the air pump obliquely downward at the screening plate, when the air pump is started, the airflow blows obliquely downward from the top to the screen, which can change the airflow direction and pressure distribution near the screening plate to a certain extent. In this way, the remaining sand and gravel are pushed by the airflow and move from the screening plate to the feed port. This setting utilizes the flushing and pushing effect of the airflow, just like using an invisible broom to sweep the sand and gravel through the feed port and into the feed trough, so that it slides out through the receiving trough, and the gravel that does not meet the discharge standard is crushed for the second time. By setting the receiving shell in an arc shape, it is avoided that when the crushed gravel is screened, the gravel during screening will move upward in the receiving shell; Preferably, the screening component comprises a screening shell, the top of the screening shell is fixedly connected to the inner side of the crushing box, both sides of the screening shell are fixedly connected with fixed plates, the bottom of the fixed plate is fixedly connected with an electric hydraulic cylinder, the inner side of the screening shell is slidably connected with the screening plate, the output end of the electric hydraulic cylinder is fixedly connected to the bottom of the screening plate, the inner side of the screening shell is symmetrically provided with sliding grooves, the upper and lower sides of the screening plate are fixedly connected with baffles, the side surfaces of the baffles are slidably connected to the inner sides of the sliding grooves, the inner side of the screening shell is fixedly connected with a connecting frame, the connecting frame is arranged at the bottom of the screening plate, the top of the connecting frame is fixedly connected with an ejection mechanism, and the inner side of the screening shell is provided with a plurality of movable frames. Both sides of the wall are provided with feeding grooves, and the inner side of the feeding groove is fixedly connected to the side of the receiving shell away from the receiving groove; the sand and gravel crushed by the crushing roller fall on the screening plate, and the screening plate is driven to move up and down in the screening shell through the output end of the electric hydraulic cylinder by opening the electric hydraulic cylinder, so as to screen the crushed gravel, and the upper and lower baffles are driven by the screening plate to move in the sliding groove, so as to avoid the gravel on the screening plate from falling through the sliding groove when the screening plate is performing the screening work, and at the same time, when the screening plate moves downward, the mesh holes of the screening plate are squeezed with the ejection mechanism, so that the ejection mechanism ejects the gravel stuck in the mesh holes of the screening plate; Preferably, the ejection mechanism includes an ejection rod, the bottom of the ejection rod is fixedly connected to the top of the connecting frame, a notch is provided on the side of the ejection rod, a slider is slidably connected to the inner side of the notch, a sliding rod is fixedly connected to the side of the slider, the side of the sliding rod is slidably connected to the inner side of the ejection rod, an ejector pin is fixedly connected to the top of the sliding rod, the ejector pin is concentrically arranged with the mesh of the screen plate, a first spring is sleeved on the ejection rod, the top of the first spring is fixedly connected to the ejector pin, and the bottom of the first spring is fixedly connected to the top of the ejection rod; in order to prevent the sand and gravel from getting stuck in the mesh of the screen plate when the screen plate is performing screening work, The phenomenon of causing blockage of the screen plate is that when the screen plate is driven to move downward by the output end of the electric hydraulic cylinder, the mesh of the screen plate moves toward the top of the ejector rod. When the mesh of the screen plate is blocked by gravel, the ejector rod ejects the impurities stuck in the mesh of the screen plate through the ejector pin. When the extrusion force between the ejector pin and the gravel stuck in the mesh of the screen plate is greater than the tension of the first spring, the ejector pin drives the slider to slide in the slot through the sliding rod, thereby avoiding excessive extrusion force between the ejector pin and the impurities stuck in the mesh of the screen plate, which will squeeze and damage the impurities in the ejector pin. At the same time, by avoiding excessive friction between the gravel and the mesh of the screen plate, the aperture of the mesh is enlarged. Preferably, the water storage component comprises a water tank, the top of the water tank is fixedly connected with a connecting pipe, the top of the connecting pipe is fixedly connected with the bottom of the screening shell, the inner side of the water tank is fixedly connected with a cleaning mechanism, the bottom of the connecting pipe is fixedly connected with the inner side of the cleaning mechanism, and the bottom of the inner cavity of the water tank is fixedly connected with a collecting mechanism; the crushed stones that fall through the screening plate enter the cleaning mechanism through the connecting pipe, thereby cleaning the crushed stones, and at the same time, the collecting mechanism rotates at the bottom of the inner cavity of the water tank, thereby collecting the crushed stones that fall into the water tank; Preferably, the cleaning mechanism comprises a cleaning shell, the side surface of the cleaning shell is fixedly connected to the inner side of the water tank, one end of the cleaning shell is fixedly connected to the second motor, the side surface of the cleaning shell is evenly provided with through holes, the inner side of the cleaning shell is rotatably connected to a spiral plate, one end of the spiral plate is fixedly connected to the output end of the second motor; after adding a large amount of clean water to the cleaning shell, the gravel enters the cleaning shell through the connecting pipe, and by turning on the second motor, the spiral plate is driven to rotate in the cleaning shell through the output end of the second motor, thereby spirally rotating the gravel entering the cleaning shell, and at the same time, the gravel is rotated and cleaned, and the sand and gravel raw materials are mined and crushed. Soil, stone powder and other impurities will be mixed in during the crushing process. For example, soil is wrapped on the surface of sand and gravel particles. If it is not cleaned and used directly in cement rod production, weak areas will be formed in the concrete. When the cement rod is subjected to external force, these parts with more soil are prone to cracks, reducing the strength and durability of the cement rod. Too high a content of stone powder will also have an adverse effect on the quality of the cement rod. Stone powder will increase the water consumption of concrete, resulting in a larger water-cement ratio, thereby reducing the strength of the concrete. After cleaning, the stone powder content can be effectively controlled to ensure the quality of the cement rod. At the same time, it can be rotated in the cleaning shell through the spiral plate, thereby driving the cleaned crushed stone to perform spiral discharge through the other end of the cleaning shell; Preferably, the collecting mechanism comprises a collecting shell, the bottom of the collecting shell is fixedly connected to the bottom of the inner cavity of the water tank, the top of the collecting shell is fixedly connected to a mesh plate, the bottom of the collecting shell is fixedly connected to a third motor, the top of the mesh plate is rotatably connected to a contact assembly, and the output end of the third motor is fixedly connected to the bottom of the contact assembly; to prevent part of the gravel from falling into the water tank through the through hole on the cleaning shell when cleaning the gravel, the third motor is turned on, and the contact assembly is driven to rotate on the top of the mesh plate through the output end of the third motor, so that the gravel that falls on the bottom of the inner cavity of the water tank is swept into the collecting shell for collection; Preferably, the contact assembly includes a rotating block, a rotating rod is fixedly connected to the side of the rotating block, a cleaning brush is fixedly connected to the side of the rotating rod close to the mesh plate, and the cleaning brush contacts the top of the mesh plate on the side of the rotating rod away from the rotating rod, and the rotating plate is fixedly connected to the side of the mesh plate close to the mesh plate; driven by the output end of the third motor, the rotating block rotates on the top of the mesh plate, so that the rotating block drives the cleaning brush to clean the top of the mesh plate through the rotating rod, thereby preventing the sand and soil in the sand and gravel from accumulating on the mesh plate and interfering with the collection of gravel in the water tank. At the same time, when the rotating block rotates, it is brought to multiple arc blocks on the top of the mesh plate through the rotating plate to rotate, and by arranging an arc block at the bottom of the rotating plate, the arc block can bring the gravel that falls around the mesh plate into the inner cavity of the collection shell for collection, thereby preventing the gravel remaining in the water tank from interfering with the drainage work when changing water in the water tank.

[0005] The beneficial effects of the present invention are as follows: 1. The present invention sets a material collecting mechanism. When the screening component is finished, after the sand and gravel that do not meet the discharge standard are screened out on the screening plate, air pumps are symmetrically arranged on both sides of the crushing box close to the feed trough. The air pump on one side works for suction, and the air pump on the other side works for exhaust. The air pumps on both sides work at the same time, and the generated airflow can form a balanced pushing force on the feed trough. The airflows on both sides can work together to push the remaining sand and gravel from various positions of the screening plate toward the feed trough, so that they enter the feed trough, ensuring that the sand and gravel on the entire screening plate can be effectively cleaned and recovered.

[0006] 2. The present invention provides an ejection mechanism to prevent the sand and gravel from getting stuck in the mesh holes of the screen plate when passing through the screen plate during screening, thereby causing blockage of the screen plate. When the screen plate is driven downward by the output end of the electric hydraulic cylinder, the mesh holes of the screen plate move toward the top of the ejection rod. When the mesh holes of the screen plate are blocked by gravel, the ejection rod ejects the impurities stuck in the mesh holes of the screen plate through the ejector pin. When the extrusion pressure between the ejector pin and the gravel stuck in the mesh holes of the screen plate is greater than the pulling force of the first spring, the ejector pin drives the slider to slide in the slot through the sliding rod, thereby preventing the extrusion pressure between the ejector pin and the impurities stuck in the mesh holes of the screen plate from being too large, thereby causing extrusion damage to the impurities in the ejector pin. At the same time, by preventing the friction between the gravel and the mesh holes of the screen plate from being too large, the aperture of the mesh holes is enlarged.

[0007] 3. The present invention provides a cleaning mechanism. After adding a large amount of clean water into the cleaning shell, the crushed stones enter the cleaning shell through the connecting pipe. By turning on the second motor, the spiral plate is driven to rotate in the cleaning shell through the output end of the second motor, so that the crushed stones entering the cleaning shell are spirally rotated and the crushed stones are rotated and cleaned at the same time. Sand and gravel raw materials may be mixed with soil, stone powder and other impurities during the mining and crushing process. For example, soil is wrapped on the surface of sand and gravel particles. If it is directly used for cement rod production without cleaning, weak areas will be formed in the concrete. When the cement rod is subjected to external force, these parts containing more soil are prone to cracks, which reduces the strength and durability of the cement rod. Too high stone powder content will also have an adverse effect on the quality of the cement rod. Stone powder will increase the water consumption of concrete, resulting in a larger water-cement ratio, thereby reducing the strength of the concrete. After cleaning, the stone powder content can be effectively controlled to ensure the quality of the cement rod. At the same time, the spiral plate can be rotated in the cleaning shell, thereby driving the cleaned crushed stones to perform spiral discharging through the other end of the cleaning shell.

[0008] 4. The present invention sets a collecting mechanism to prevent part of the gravel from falling into the water tank through the through holes on the cleaning shell when cleaning the gravel. By turning on the third motor, the output end of the third motor drives the contact assembly to rotate on the top of the mesh plate, thereby sweeping the gravel that falls to the bottom of the inner cavity of the water tank into the collecting shell for collection.

The stone powder will increase the water consumption of the concrete, resulting in a larger water-cement ratio, thereby reducing the strength of the concrete. After cleaning, the stone powder content can be effectively controlled to ensure the quality of the cement rod. At the same time, the spiral plate 233 can rotate in the cleaning shell 231, thereby driving the cleaned crushed stone to perform spiral discharging through the other end of the cleaning shell 231; The collecting mechanism 24 includes a collecting shell 241, the bottom of which is fixedly connected to the bottom of the inner cavity of the water tank 21, the top of which is fixedly connected to a mesh plate 242, the bottom of which is fixedly connected to a third motor 243, the top of which is rotatably connected to a contact assembly 244, and the output end of the third motor 243 is fixedly connected to the bottom of the contact assembly 244; when cleaning the gravel, part of the gravel is prevented from falling into the water tank 21 through the through hole on the cleaning shell 231, and the third motor 243 is turned on, and the output end of the third motor 243 drives the contact assembly 244 to rotate on the top of the mesh plate 242, so that the gravel falling into the bottom of the inner cavity of the water tank 21 is swept into the collecting shell 241 for collection; The contact assembly 244 includes a rotating block 2441, a rotating rod 2442 is fixedly connected to the side of the rotating block 2441, a cleaning brush 2443 is fixedly connected to the side of the rotating rod 2442 close to the mesh plate 242, and the cleaning brush 2443 is in contact with the top of the mesh plate 242 on the side away from the rotating rod 2442, a rotating plate 2444 is fixedly connected to the side of the rotating block 2441 away from the rotating rod 2442, and an arc block 2445 is fixedly connected to the side of the rotating plate 2444 close to the mesh plate 242; driven by the output end of the third motor 243, the rotating block 2441 rotates on the top of the mesh plate 242, so that the rotating block 2441 passes through the rotating rod 2442, The cleaning brush 2443 is driven to clean the top of the mesh plate 242, so as to prevent the sand and soil residue in the sand and gravel from accumulating on the mesh plate 242 and interfering with the collection of the gravel in the water tank 21. At the same time, when the rotating block 2441 rotates, it is brought to the top of the mesh plate 242 by the rotating plate 2444 to rotate the plurality of arc blocks 2445. By arranging the arc blocks 2445 at the bottom of the rotating plate 2444, the arc blocks 2445 can bring the gravel dropped around the mesh plate 242 into the inner cavity of the collection shell 241 for collection, so as to prevent the gravel residue in the water tank 21 from interfering with the drainage work when the water in the water tank 21 is changed. The specific workflow is as follows: During operation, the sand and gravel are placed in the crushing part 1, and the crushing part 1 crushes the sand and gravel. The crushed sand and gravel are screened by the screening part 3, and then enter the water storage part 2 to clean the crushed sand and gravel. Put the sand and gravel into the crushing box 11 through the feed port 12, turn on the first motor 13, and drive the crushing roller 14 to rotate in the crushing box 11 through the output end of the first motor 13, so as to crush the sand and gravel, and screen the crushed sand and gravel through the screening component 3, so as to screen out the sand and gravel that does not meet the crushing standard. When the feeding of sand and gravel into the crushing box is stopped, the sand and gravel remaining on the screening component 3 is transported into the crushing box 11 through the receiving mechanism 15 for secondary crushing; When the screening component 3 is finished and the sand and gravel that do not meet the discharge standard are screened out on the screening plate 34, air pumps 153 are symmetrically arranged on both sides of the crushing box 11 near the feed trough 37. The air pump 153 on one side is for exhaust work, and the air pump 153 on the other side is for exhaust work. The air pumps 153 on both sides work at the same time, and the air flow generated can form a balanced pushing force on the feed trough 37. The air flows on both sides can work together to push the remaining sand and gravel from various positions of the screening plate 34 toward the feed trough 37, so as to enter the feed trough 37, thereby ensuring that the sand and gravel on the entire screening plate 34 can be effectively cleaned and recovered. By turning on the air pump 153, by aligning the air outlet of the air pump 153 obliquely downward toward the screening plate 34 When the air pump 153 is started, the airflow blows obliquely downward from above toward the screen, which can change the airflow direction and pressure distribution near the screen plate 34 to a certain extent. In this way, the remaining sand and gravel are pushed by the airflow and move from the top of the screen plate 34 to the direction of the feed port 12. This setting utilizes the flushing and pushing effect of the airflow, just like using an invisible broom to sweep the sand and gravel through the feed port 12 and into the feed trough 37, so that it slides out through the receiving trough 151, and the gravel that does not meet the discharge standard is crushed for the second time. By setting the receiving shell 152 in an arc shape, it is avoided that when the crushed gravel is screened, the crushed stone during screening will move upward in the receiving shell 152; The sand and gravel crushed by the crushing roller 14 falls on the screening plate 34. By opening the electric hydraulic cylinder 33, the screening plate 34 is driven to move up and down in the screening housing 31 through the output end of the electric hydraulic cylinder 33, so as to screen the crushed gravel. The upper and lower baffles 36 are driven by the screening plate 34 to move in the sliding groove 35, so as to prevent the gravel on the screening plate 34 from falling through the sliding groove 35 when the screening plate 34 is performing the screening work. At the same time, when the screening plate 34 moves downward, the mesh of the screening plate 34 is squeezed by the ejection mechanism 39, so that the ejection mechanism 39 ejects the gravel stuck in the mesh of the screening plate 34. In order to prevent the sand and gravel from getting stuck in the mesh of the screen plate 34 when passing through the screen plate 242 during the screening operation, thereby blocking the screen plate 242, when the screen plate 34 is driven downward by the output end of the electric hydraulic cylinder 33, the mesh of the screen plate 242 moves toward the top of the ejector rod 391. When the mesh of the screen plate 242 is blocked by gravel, the ejector rod 391 ejects the impurities stuck in the mesh of the screen plate 34 through the ejector pin 395. When the squeezing force between the ejector pin 395 and the crushed stone stuck in the mesh of the screen plate 242 is greater than the pulling force of the first spring 396, the ejector pin 395 drives the slider 393 to slide in the slot 392 through the sliding rod 394, thereby preventing the ejector pin 395 from being squeezed and damaged by the impurities stuck in the mesh of the screen plate 34 due to excessive squeezing force, and at the same time preventing the crushed stone from being too large and the mesh of the screen plate 34 from being too large, thereby causing the aperture of the mesh to expand; The fallen gravels are screened by the screening plate 34 and enter the cleaning mechanism 23 through the connecting pipe 22, so as to clean the crushed gravels. At the same time, the collecting mechanism 24 rotates at the bottom of the inner cavity of the water tank 21, so as to collect the gravels that fall into the water tank 21. After adding a large amount of clean water to the cleaning shell 231, the crushed stones enter the cleaning shell 231 through the connecting pipe 22, and the second motor 232 is turned on to drive the spiral plate 233 to rotate in the cleaning shell 231 through the output end of the second motor 232, so that the crushed stones entering the cleaning shell 231 are spirally rotated and the crushed stones are rotated and cleaned at the same time. Sand and gravel raw materials will be mixed with soil, stone powder and other impurities during the mining and crushing process. For example, soil is wrapped on the surface of sand and gravel particles. If they are not cleaned and used directly for cement pole production, it will Weak areas are formed in the concrete. When the cement rod is subjected to external force, these parts with more soil are prone to cracks, reducing the strength and durability of the cement rod. Too high a stone powder content will also have an adverse effect on the quality of the cement rod. Stone powder will increase the water consumption of concrete, resulting in a larger water-cement ratio, thereby reducing the strength of the concrete. After cleaning, the stone powder content can be effectively controlled to ensure the quality of the cement rod. At the same time, the spiral plate 233 can rotate in the cleaning shell 231, thereby driving the cleaned crushed stone to perform spiral discharge through the other end of the cleaning shell 231; To prevent the gravels from falling into the water tank 21 through the through holes on the cleaning housing 231 when cleaning the gravels, the third motor 243 is turned on, and the output end of the third motor 243 drives the contact assembly 244 to rotate on the top of the mesh plate 242, so that the gravels that fall into the bottom of the inner cavity of the water tank 21 are swept into the collection housing 241 for collection; Driven by the output end of the third motor 243, the rotating block 2441 rotates on the top of the mesh plate 242, so that the rotating block 2441 drives the cleaning brush 2443 to clean the top of the mesh plate 242 through the rotating rod 2442, thereby preventing the sand and soil residue in the sand and gravel from accumulating on the mesh plate 242 and interfering with the collection of gravel in the water tank 21. At the same time, when the rotating block 2441 rotates, it is brought to the top of the mesh plate 242 by the rotating plate 2444 to cause multiple arc blocks 2445 to rotate. By arranging the arc blocks 2445 at the bottom of the rotating plate 2444, the arc blocks 2445 can bring the gravel that falls around the mesh plate 242 into the inner cavity of the collecting shell 241 for collection, thereby preventing the gravel remaining in the water tank 21 from interfering with the drainage work when the water in the water tank 21 is changed.
