Description

Technical Field

[0001] This application relates to the field of water conservancy engineering, and in particular to a self-compacting rockfill receiving device with self-cleaning function. Background Technology

[0002] Self-compacting concrete is one of the commonly used technologies in the construction of large-volume concrete projects.

[0003] Patent CN117163543A discloses a concrete transport chute device for a high-face rockfill dam, comprising a chute, a top opening fixedly connected to one side of the chute, and a bottom opening fixedly connected to the other side of the chute. Erection mechanisms are installed on both sides of the chute, and a material distribution mechanism is installed at the bottom of the chute. Each erection mechanism includes two connecting blocks, with a clamping plate fixedly connected to the middle of each connecting block. An installation block is slidably connected to one side of the clamping plate, and a housing is fixedly connected to the side of the installation block away from the chute. A slider is slidably connected inside the housing. Through the cooperation of the material distribution mechanism and the erection mechanism, the chute device can be easily dismantled at the bottom as construction progresses, without requiring workers to enter the dam construction area. This also reduces the time required for subsequent leveling of the dam concrete, improving construction efficiency.

[0004] In the process of realizing the above application, the inventors discovered that the technology has at least the following problems: during the transportation of the piled stones, the piled stones fall directly to the ground, which can easily damage the ground, especially on cement or asphalt roads, causing irreversible damage. Summary of the Invention

[0005] To reduce the damage to the ground caused by unloading riprap, this application provides a self-compacting riprap receiving device with a self-cleaning function.

[0006] The self-cleaning, self-compacting rockfill receiving device provided in this application adopts the following technical solution:

[0007] A self-cleaning, self-compacting rockfill receiving device includes a first receiving plate, a second receiving plate fixed on the first receiving plate, a plurality of discharge grooves on the second receiving plate, a pusher rod slidably disposed between the first receiving plate and the second receiving plate, a plurality of push grooves corresponding to the discharge grooves on the pusher rod, and a pusher plate rotatably disposed on the inner sidewall of the pusher groove, and the pusher plate can only rotate in the direction of material accumulation.

[0008] By adopting the above technical solution, after the rock pile is unloaded, it will be transferred to the second receiving plate and will not come into direct contact with the road surface. Since the second receiving plate has a large area, the damage to the ground is small during the rock pile unloading process, which is suitable for cement roads or asphalt roads. At the same time, a first receiving plate is set at the bottom of the second receiving plate. Smaller rock piles can be transferred to the first receiving plate through the discharge chute, and the smaller rock piles can be collected by the movement of the push rod, which is convenient for cleaning up smaller rock piles.

[0009] Optionally, a support plate can be detachably provided at the end of the first receiving plate. A first buffer plate is provided on the support plate. The upper surface of the first buffer plate is inclined. A first buffer cylinder is fixed at the bottom of the first buffer plate. A second buffer cylinder is fixed on the support plate. The second buffer cylinder passes through the first buffer cylinder. A buffer spring is provided between the first buffer cylinder and the second buffer cylinder.

[0010] By adopting the above technical solution, the bottom of the support plate is provided with a first buffer cylinder, a second buffer cylinder, and a buffer spring, which facilitates the receipt of piled stones and plays a preliminary buffering role. At the same time, the upper surface of the first buffer plate is inclined, which facilitates the transfer of the piled stones to the second receiving plate after receiving them.

[0011] Optionally, a first stabilizing plate is fixed to the bottom of the first buffer cylinder, and a second stabilizing plate is rotatably mounted on both ends of the first stabilizing plate. The second stabilizing plate is inclined and a stabilizing spring is fixed between the two second stabilizing plates. The bottom of the second stabilizing plate is attached to the end face of the second receiving plate.

[0012] By adopting the above technical solution, the first stabilizing plate, the second stabilizing plate, and the stabilizing spring work together to support the first buffer plate and provide a buffering effect. At the same time, by adjusting the length of the second stabilizing plate, the piled rocks can fall onto the second stabilizing plate first during the transfer to the second receiving plate. The second stabilizing plate is tilted to facilitate the transfer of the piled rocks.

[0013] Optionally, the support plate is provided with two second buffer plates, which are respectively placed on both sides of the first buffer plate. The upper surface of the second buffer plate is inclined. The side walls of the first buffer plate are fixed with cooperating plates. The end face of the second buffer plate is lower than that of the first buffer plate. The bottom structure of the second buffer plate is the same as that of the first buffer plate.

[0014] By adopting the above technical solution, the first buffer plate can drive the second buffer plate to move during the movement, and the second buffer plate can provide buffering force for the first buffer plate again, reducing the possibility of damage to the first buffer plate.

[0015] Optionally, a vertically arranged upright plate is fixed on the support plate, a drive disk is rotatably connected to the upright plate, a drive gear is fixed to the end face of the drive disk, a drive rack is fixed to the side wall of the second buffer plate, and the drive rack meshes with the drive gear; a drive rod is rotatably connected to the end face of the drive disk, and the end of the drive rod is rotatably connected to the end of the push rod.

[0016] By adopting the above technical solution, the movement of the second buffer plate can drive the drive disc to rotate, thereby driving the drive rod to move. During the movement, the drive rod pushes the push rod to move, which facilitates the cleaning process of the piled stone and crushed stone.

[0017] Optionally, a first collecting block is slidably disposed inside the feeding trough, and a connecting groove is provided on the inner side wall of the feeding trough. A connecting rod is fixed between two adjacent first collecting blocks and the connecting rod passes through the connecting groove. A collecting groove is provided on the first collecting block, and a second collecting block is slidably disposed on the inner side wall of the collecting groove, and the upper end face of the second collecting block is inclined.

[0018] By adopting the above technical solution, during the sliding process of the first collecting block, when the first collecting block slides away from the first receiving plate, the second collecting block can push the pile of stones away from the first receiving plate under its action; when the first collecting block slides towards the first receiving plate, since the upper surface of the second collecting block is inclined, the second collecting block moves downward in the vertical direction under the action of the inclined upper surface, and will not push the pile of stones towards the first receiving plate. After moving away from the pile of stones, the second collecting block extends under the action of the reset spring, and can continue to push the pile of stones during the movement.

[0019] Optionally, the feeding trough is provided with a pushing spring that pushes the first collecting block close to the support plate, the side wall of the pushing rod is fixed with a pushing protrusion, a control block is slidably arranged on the first collecting block, and the side wall of the control block is provided with a control guide surface.

[0020] By adopting the above technical solution, when the push rod moves away from the first receiving plate, it pushes the protrusion to contact the control block, thereby driving the first collecting block to move. When it moves to the return plate, it pushes the protrusion to separate from the control block. Under the action of the push spring, the first collecting block is reset. At the same time, when the push rod moves towards the first receiving plate, the control block will not interfere with the movement of the push rod due to the existence of the control guide surface.

[0021] Optionally, the drive plate is provided with an adjustment groove, an adjustment block is slidably disposed in the adjustment groove, an adjustment bolt for positioning the adjustment block is slidably disposed on the adjustment block, an installation block is rotatably disposed on the end face of the adjustment block, and the drive rod is mounted on the installation block.

[0022] By adopting the above technical solution, the position of the driving rod on the driving plate can be adjusted by adjusting the position of the adjusting block in the adjusting groove. Since the linear velocity of each position on the driving plate is different, the movement distance of the push rod can be controlled.

[0023] Optionally, a connecting part is fixed on the support plate, a first connecting groove for the connecting part to pass through is provided on the first receiving plate, a reinforcing block is slidably provided on the side wall of the connecting part, and a second connecting groove for the reinforcing block to pass through is provided on the inner side wall of the first connecting groove.

[0024] By adopting the above technical solution, the reinforcing block is inserted into the second connecting groove, which simultaneously serves as a fixation and buffer, effectively reducing the possibility of the support plate separating from the first receiving plate due to vibration caused by the contact between the piled stones and the first receiving plate.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. After the rock pile is unloaded, it will be transferred to the second receiving plate, and will not come into direct contact with the road surface. Because the second receiving plate has a larger area, the damage to the ground during the rock pile unloading process is smaller, which is suitable for cement roads or asphalt roads. At the same time, the first receiving plate is set at the bottom of the second receiving plate. Smaller rock piles can be transferred to the first receiving plate through the discharge chute, and the movement of the push rod can collect the smaller rock piles, which is convenient for cleaning up smaller crushed stone piles.

[0027] 2. The bottom of the support plate is equipped with a first buffer cylinder, a second buffer cylinder, and a buffer spring, which facilitates the reception of piled stones and plays a preliminary buffering role. At the same time, the upper surface of the first buffer plate is inclined to facilitate the transfer of the piled stones to the second receiving plate after receiving them.

[0037] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0038] This application discloses a self-compacting riprap receiving device with a self-cleaning function. (Refer to...) Figure 1 and Figure 2 The self-cleaning, self-compacting stone receiving device includes a first receiving plate 1, which is placed on the ground. A second receiving plate 2 is provided on the first receiving plate 1. The second receiving plate 2 is the same size as the first receiving plate 1 and is fixed to the upper surface of the first receiving plate 1 by bolts. There is a certain gap between the first receiving plate 1 and the second receiving plate 2. Several discharge troughs 3 are provided on the second receiving plate 2. The discharge troughs 3 are parallel to each other and their length direction is the same as that of the second receiving plate 2. The discharge troughs 3 penetrate the second receiving plate 2 along its thickness direction, which facilitates the transfer of crushed stone to the first receiving plate 1 during the placement of the stone pile, thereby facilitating the collection and cleaning of the crushed stone.

[0039] Reference Figure 1 , Figure 2 and Figure 3 A push rod 4 is slidably arranged between the first receiving plate 1 and the second receiving plate 2. The push rod 4 can slide along the length direction of the feeding trough between the first receiving plate 1 and the second receiving plate 2. At the same time, a number of pushing grooves 5 are opened on the push rod 4. The number of pushing grooves 5 correspond one-to-one with a number of discharging grooves 3. The inner side wall of the pushing groove 5 is rotatably connected to a push plate 6 through a rotating shaft. The ends of the first receiving plate 1 and the second receiving plate 2 in the length direction are set open. The push plate 6 only rotates in the direction of the pile material accumulation.

[0040] Reference Figure 1 and Figure 2 A support plate 7 is detachably connected to one end of the first receiving plate 1 along its length. The support plate 7 is set on the ground, and a first buffer plate 8 is set on the support plate 7. A first buffer cylinder 9 is integrally formed and fixed to the bottom of the first buffer plate 8. A second buffer cylinder 10 is integrally formed and fixed to the support plate 7. The second buffer cylinder 10 passes through the first buffer cylinder 9, and the outer wall of the second buffer cylinder 10 is attached to the inner wall of the first buffer cylinder 9. A buffer spring is set inside the second buffer cylinder 10. One end of the buffer spring abuts against the end face of the support plate 7, and the other end abuts against the bottom of the first buffer plate 8. The buffer spring is used to push... The first buffer plate 8 moves away from the support plate 7. The upper surface of the first buffer plate 8 is inclined. The first buffer plate 8 is used to receive the piled stones. Because its upper surface is inclined, it is easy to transfer the piled stones to the first receiving plate 1 and the second receiving plate 2. When the push rod 4 moves away from the first buffer plate 8, the push plate 6 cannot rotate, which makes it easy to push the crushed stones between the first receiving plate 1 and the second receiving plate 2. When the push rod 4 moves towards the first buffer plate 8, the push plate 6 contacts the crushed stones and rotates, but does not drive the crushed stones toward the first buffer plate 8, which facilitates the process of cleaning the crushed stones.

[0041] Reference Figure 1 and Figure 2 The bottom of the first buffer cylinder 9 is fixed with a first stabilizing plate 12 by an integral molding process. The length direction of the first stabilizing plate 12 is the same as the length direction of the feeding trough 3. Both ends of the first stabilizing plate 12 are rotatably connected to second stabilizing plates 13 via rotating shafts. The second stabilizing plates 13 are inclined, and their ends abut against the upper surface of the second receiving plate 2. A stabilizing spring 14 is fixed between the two second stabilizing plates 13. The two ends of the stabilizing spring 14 are respectively fixed to the opposite end faces of the two second stabilizing plates 13. The stabilizing spring 14 is used to pull the two second stabilizing plates 13 toward each other. The second stabilizing plates 13 mainly play a supporting role and can effectively reduce the first There is a possibility of positional displacement between the buffer cylinder 9 and the second buffer cylinder 10. At the same time, the second stabilizing plate 13 has a buffering effect. After the first buffer plate 8 receives the piled stones, it moves towards the ground, driving the first buffer cylinder 9 to move, thereby driving the first stabilizing plate 12 to move. Since the end of the second stabilizing plate 13 abuts against the second receiving plate 2, the end of the second stabilizing plate 13 that abuts against the second receiving plate 2 moves along the length direction of the second receiving plate 2. At the same time, due to the force of the stabilizing spring 14, the two second stabilizing plates 13 tend to move closer to each other, thus providing a buffering force. In addition, the second buffer plate 15 that moves on the second receiving plate 2 has the effect of pushing the piled stones on the second receiving plate 2 to move.

[0042] Reference Figure 1 and Figure 2 Two second buffer plates 15 are provided on the support plate 7. The two second buffer plates 15 are respectively placed on both sides of the first buffer plate 8, and the upper surfaces of the two second buffer plates 15 are inclined in the same direction as the first buffer plate 8. The bottom buffer structure of the second buffer plate 15 is the same as the bottom structure of the first buffer plate 8. The upper surface of the second buffer plate 15 is lower than that of the first buffer plate 8. The first buffer plate 8 is fixed with a cooperating plate 16 on both sides. The cooperating plate 16 is inclined and can fit against the upper surface of the second buffer plate 15. During the movement of the first buffer plate 8, it can drive the cooperating plate 16 to abut against the upper surface of the second buffer plate 15, thereby driving the second buffer plate 15 to move. The second buffer plate 15 itself has a buffering function and can be used to receive piled stones. At the same time, the second buffer plate 15 can provide buffering for the first buffer plate 8, improving the buffering capacity of the first buffer plate 8 to receive piled stones.

[0043] Reference Figure 1 , Figure 2 and Figure 4 A vertical plate 17 is integrally formed and fixed on the support plate 7. The vertical plate 17 is vertically arranged and a drive plate 18 is rotatably connected to the vertical plate 17 via a rotating shaft. A drive gear 19 is fixed to the end face of the drive plate 18 by bolts, and the drive gear 19 is coaxial with the drive plate 18. A drive rack 20 is fixed to the side wall of the second buffer plate 15 by bolts. The drive rack 20 meshes with the drive gear 19. The movement of the first buffer plate 8 can drive the movement of the second buffer plate 15. The movement of the second buffer plate 15 drives the movement of the drive rack 20. The drive rack 20 drives the drive gear 19 to rotate, thereby driving the drive plate 18 to rotate.

[0044] Reference Figure 1 , Figure 4 and Figure 5 An adjustment groove 30 is provided on the drive plate 18, and an adjustment block 31 is slidably disposed in the adjustment groove 30. The adjustment block 31 can slide along the length of the adjustment groove 30 within the groove. An adjustment bolt 32 passes through the adjustment block 31, and the adjustment bolt 32 is threadedly connected to the adjustment block 31. By rotating the adjustment bolt 32, the end of the adjustment bolt 32 can abut against the end face of the drive plate 18, thereby fixing the position of the adjustment block 31. A drive rod 21 is provided on the adjustment block 31, and the drive rod 21 is rotatably connected to the end of the drive plate 18. The end of the drive rod 21 is rotatably connected to the end of the push rod 4 via a rotating shaft. The rotation of the drive disc 18 causes the drive rod 21 to move with the drive disc 18, thereby pushing the push rod 4 between the first receiving plate 1 and the second receiving plate 2, so that the drive rod 21 can move without an external power supply. The end face of the adjusting block 31 is rotatably provided with a mounting block 33 via a rotating shaft. The drive rod 21 is mounted on the mounting block 33. Since the mounting block 33 can rotate, the drive rod 21 will move on the drive disc 18 during the rotation of the drive disc 18.

[0045] Reference Figure 1 and Figure 2 The feeding trough 3 is equipped with a first collecting block 22, which can slide along the length of the feeding trough 3. A connecting groove 23 is formed on the inner wall of the feeding trough 3, with its length parallel to that of the feeding trough 3. The connecting groove 23 passes through two adjacent feeding troughs 3. A connecting rod 24 is bolted between two adjacent first collecting blocks 22, and the connecting rod 24 passes through the connecting groove 23, preventing the first collecting block 22 from detaching from the feeding trough 3. A collecting groove 25 is formed on the first collecting block 22, which passes through it vertically. A second collecting block 26 passes through the collecting groove 25 and can slide vertically within it. The upper surface of the second collecting block 26 is inclined, and its inclination direction is opposite to that of the first buffer plate 8. A reset groove is formed on the inner wall of the collecting groove 25, and the reset groove is vertically positioned. The 6th sidewall is fixed with a reset block by integral molding. The reset block passes through the reset groove and a reset spring is provided in the reset groove. One end of the reset spring is attached to the end face of the reset block and the other end is attached to the bottom of the inner side of the reset groove. The reset spring is used to push the second collecting block 26 to move upward in the vertical direction. During the sliding process of the first collecting block 22, when the first collecting block 22 slides away from the first receiving plate 1, the action of the second collecting block 26 can push the pile of stones to move away from the first receiving plate 1. When the first collecting block 22 slides towards the first receiving plate 1, since the upper end face of the second collecting block 26 is inclined, the second collecting block 26 moves downward in the vertical direction under the action of the inclined upper end face. It will not push the pile of stones close to the first receiving plate 1. After moving away from the pile of stones, the second collecting block 26 extends under the action of the reset spring. During the movement, it can continue to push the pile of stones.

[0046] Reference Figure 2 , Figure 3 and Figure 6A pushing spring 11 is installed inside the feeding trough 3. The pushing spring 11 is placed in the connecting groove 23 inside the feeding trough 3, which reduces the possibility of interference with the movement of the pushing spring 11 during the transfer of the piled stone and crushed stone to the second receiving plate 2. The side wall of the pushing rod 4 is fixed with a pushing protrusion 27 by integral molding. A control groove is opened on the first collecting block 22. The axis of the control groove is set vertically. A control block 28 is inserted in the control groove and can slide in the control groove. A control spring is set in the control groove to push the control block 28 away from the inside of the control groove. A control guide surface 29 is opened on the side wall of the control block 28. The end of the control guide surface 29 near the first receiving plate 1 in the horizontal direction is lower than the end away from the first receiving plate 1. At the end, a return plate is fixed to the bottom of the first receiving plate 1. A return guide surface is provided at the end of the return plate. A return block is fixed to the side wall of the control block 28. The return block contacts the return guide surface and can push the control block 28 toward the inside of the control groove. During the movement of the push rod 4, when the push rod 4 moves away from the first receiving plate 1, it pushes the protrusion 27 to contact the control block 28, thereby driving the first collecting block 22 to move. When it moves to the return plate, it pushes the protrusion 27 to separate from the control block 28. Under the action of the push spring 11, the first collecting block 22 is reset. At the same time, when the push rod 4 moves toward the first receiving plate 1, the control block 28 will not interfere with the movement of the push rod 4 due to the presence of the control guide surface 29.

[0047] Reference Figure 2 and Figure 7 The support plate 7 is fixed with a connecting part 34 by integral molding. The first receiving plate 1 is provided with a first connecting groove 35 for the connecting part 34 to pass through. The side wall of the connecting part 34 is provided with a reinforcing groove. A reinforcing block 36 passes through the reinforcing groove and can slide inside the reinforcing groove. The inner side wall of the first connecting groove 35 is provided with a second connecting groove 37 for the reinforcing block 36 to pass through. The side wall of the reinforcing block 36 is provided with a reinforcing guide surface. A reinforcing spring is provided in the reinforcing groove for pushing the reinforcing block 36 away from the reinforcing groove. The reinforcing block 36 passes through the second connecting groove 37 and plays a role in fixing and buffering. It can effectively reduce the possibility of the support plate 7 separating from the first receiving plate 1 due to vibration caused by the contact between the piled stones and the first receiving plate.

[0048] The implementation principle of a self-cleaning, self-compacting rock-fill receiving device according to an embodiment of this application is as follows: the support plate 7 is connected to the first receiving plate and the second receiving plate. The rock-fill is poured onto the first buffer plate 8, the first buffer plate 8 contacts the second buffer plate 15, and the rock-fill is transferred to the second receiving plate. Larger rocks remain on the second receiving plate, while smaller rocks are transferred to the first receiving plate through the discharge chute 3. During the movement of the second buffer plate 15, the push rod moves, which facilitates the collection and cleaning of small rocks.

[0049] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
