[0004] In the process of implementing the above application, the inventor found that there are at least the following problems in this technology: the above cleaning device is inconvenient to move and cannot clean the stones at the construction site. Transporting the stones to the construction site after cleaning will affect construction efficiency. Summary of the Invention

[0005] In order to improve construction efficiency, the present application provides a self-compacting rock pile washing device and a rock washing method thereof.

[0006] First aspect:

[0007] The self-compacting rockfill washing device provided in this application adopts the following technical solution:

[0008] A self-compacting rock-washing device comprises two first cleaning plates, second cleaning plates being rotatably connected to opposite side walls of the two first cleaning plates, and the side walls of the two second cleaning plates being rotatably connected, cleaning channels being provided inside the first cleaning plates and the second cleaning plates, water outlet channels being provided at the bottoms of the first cleaning plates and the second cleaning plates, the water outlet channels being connected to the cleaning channels, a cleaning pipe for cleaning being fixed in the cleaning channels, and a plurality of cleaning holes being provided on the cleaning pipes at positions corresponding to the water outlet channels.

[0009] By adopting the above technical solution, during the stone cleaning process, the loading vehicle can be opened to the bottom of the first cleaning plate and the second cleaning plate, and water can be passed into the cleaning pipe. The water in the cleaning pipe is transferred to the outside through the cleaning hole and the water outlet channel, that is, transferred to the bottom of the first cleaning plate, to clean the stones on the loading vehicle. At the same time, the stones can also be cleaned during the unloading process, making the cleaning process more comprehensive. By adjusting the water pressure in the cleaning pipe, the water outlet speed of the cleaning hole can be controlled, thereby facilitating the control of the cleaning efficiency of the stones. This device can be used at the construction site and can be cleaned during the unloading process. The stones do not need to undergo an additional cleaning process, thereby improving construction efficiency.

[0010] Optionally, a support plate is fixed on the ground, a support cylinder is provided on the support plate, a support rod is fixed to the bottom of the first cleaning plate and the support rod is slidably connected to the inner wall of the support cylinder, and the support cylinder is slidably connected to the support plate.

[0011] By adopting the above technical solution, the support rod is slidably connected to the inner wall of the support tube, which is convenient for adjusting the height of the first cleaning plate so that it is suitable for loading vehicles of different heights. The support tube is slidably connected to the support plate, which is convenient for adjusting the relative position between the two first cleaning plates, that is, adjusting the width so that it is suitable for loading vehicles of different widths.

[0012] Optionally, a rotating wheel is rotatably provided at the bottom of the support rod, a control groove is provided on the side wall of the support cylinder, a driving rod is passed through the control groove, a driving groove is provided at the end of the driving rod and the rotating wheel is passed through the driving groove.

[0013] By adopting the above technical solution, the position of the rotating wheel on the inner side wall of the driving groove can be adjusted by rotating the driving rod. Since the support rod is restricted by the supporting tube, when the position of the rotating wheel in the driving groove is different, its position in the supporting tube is also different, which facilitates the adjustment of the height of the first washing plate.

[0014] Optionally, a support groove is provided at the bottom of the support plate, and two starting rods are rotatably arranged in the support groove. The ends of the starting rods are fixed to the ends of the driving rods, and a starting gear is fixed to the side wall of the starting rods. A starting motor is fixed in the support groove, and a starting screw is fixed at the rotating shaft of the starting motor, and the starting screw is engaged with the two starting gears.

[0015] By adopting the above technical solution, the rotation of the starting motor drives the starting rod to rotate, and the rotation of the starting rod drives the driving rod to rotate, so that the driving rod adjusts the position of the support rod.

[0016] Optionally, an adjustment groove is provided on the support plate, a plurality of positioning grooves are provided on the inner side wall of the adjustment groove, and a positioning block is slidably provided on the side wall of the support tube, and the positioning block is passed through the positioning groove to fix the position of the support tube.

[0017] By adopting the above technical solution, the position of the support tube is adjusted by controlling the positioning block to be placed in different positioning grooves.

[0018] Optionally, a control rod is fixed on the two support rods placed on one side of the rotating shaft of the two second cleaning plates. The control rod is arranged horizontally and has a control groove on the control rod. A control plate is rotatably arranged in the control groove. There are two control plates, and the opposite ends of the two control plates are rotatably connected to a pressing rod. A limiting rod is fixed on the side wall of the pressing rod and the limiting rod is passed through the control rod. The axial direction of the limiting rod is perpendicular to the axial direction of the control rod, and the axial direction of the pressing rod is parallel to the axial direction of the control rod.

[0019] By adopting the above technical solution, by pressing the pressing rod, the control plate can be driven to move, thereby pushing the positioning block, so that the positioning block moves toward a position close to the axis of the support tube, making it easier for the support tube to move in the adjustment groove. After releasing the pressing rod, the positioning block is reset. At this time, the positioning block is placed in the positioning groove and the support tube will not move.

[0020] Optionally, the rotation axis of the control plate and the inner side wall of the control groove is placed close to the support rod.

[0021] By adopting the above technical solution, since the rotating shaft of the control plate and the inner side wall of the control groove is placed close to the support rod, the length of the force arm of the control plate away from the support rod is greater than the length of the force arm of the control plate close to the support rod. Therefore, it is more labor-saving when pressing the pressing rod, which facilitates controlling the position of the positioning block.

[0022] Optionally, a first cooperative rod is fixed to one of the side walls of the first cleaning plate, and a second cooperative rod is fixed to the other side wall of the first cleaning plate, the first cooperative rod is U-shaped, a U-shaped tube is arranged between the first cooperative rod and the second cooperative rod, and the first cooperative rod and the second cooperative rod are both passed through the U-shaped tube, and the end of the first cooperative rod and the end of the second cooperative rod are both fixed with a blocking block, a sealing ring is fixed to the side wall of the blocking block, and the sealing ring and the U-shaped tube are in interference fit.

[0023] By adopting the above technical solution, since there is air in the U-shaped tube, the movement of the first cooperative rod can drive the second cooperative rod to move in the opposite direction, so the two first cleaning plates will move synchronously.

[0024] Optionally, a liquid medium is provided in the U-shaped tube.

[0025] By adopting the above technical solution, the compressible space of the liquid medium is smaller, which facilitates the movement process of the two first cleaning plates.

[0026] Second aspect:

[0027] The present application also provides a stone washing method applicable to the above-mentioned self-compacting rockfill washing device, comprising the following steps:

[0028] a. Start the motor to drive the control rod to rotate and adjust the height of the support rod;

[0029] b. Control the position of the support cylinder in the adjustment tank to adjust the position of the first cleaning plate;

[0030] c. Let water flow into the cleaning pipe and transfer the loading vehicle to the bottom of the first cleaning plate for unloading.

[0031] By adopting the above technical solution, the stone cleaning process is simplified and can be cleaned when unloading at the construction site, thereby improving construction efficiency.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. During the stone cleaning process, the loading vehicle can be driven to the bottom of the first and second cleaning plates, and water can be passed into the cleaning pipe. The water in the cleaning pipe is transferred to the outside through the cleaning hole and the water outlet channel, that is, transferred to the bottom of the first cleaning plate, to clean the stones on the loading vehicle. At the same time, the stones can also be cleaned during the unloading process, making the cleaning process more comprehensive. By adjusting the water pressure in the cleaning pipe, the water outlet speed of the cleaning hole can be controlled, thereby facilitating the control of the cleaning efficiency of the stones.

[0045] The following is combined with Figure 1-8 This application is described in further detail.

[0046] First aspect:

[0047] The embodiment of the present application discloses a self-compacting rock-washing device. Figure 1 and Figure 2The self-compacting rock washing device includes two first cleaning plates 1, which are both horizontally arranged and have a certain distance from the ground. The distance between the first cleaning plate 1 and the ground is sufficient for a loading vehicle to pass through and for the loading vehicle to unload. The second cleaning plates 2 are rotatably connected to the opposite end surfaces of the two first cleaning plates 1 by a rotating shaft. At the same time, the two second cleaning plates 2 are rotatably connected by a rotating shaft. By controlling the relative position between the two first cleaning plates 1, the angle between the second cleaning plate 2 and the first cleaning plate 1 can be adjusted. A cleaning channel 3 is provided inside the first cleaning plate 1 and the second cleaning plate 2, and the cleaning channel 3 passes through the first cleaning plate 1 and the second cleaning plate 2 along its own axial direction. A cleaning pipe 5 is passed through the cleaning channel 3, and the cleaning pipe 5 is fixed in the cleaning channel 3 by a clamping method. The cleaning pipe 5 is made of flexible material and water can be inletted from both ends of the cleaning pipe 5. Water outlets are provided at the bottoms of the first cleaning plate 1 and the second cleaning plate 2. The channel 4 is connected with the cleaning channel 3, and the cleaning pipe 5 is provided with a plurality of cleaning holes 6 at the position corresponding to the water outlet channel 4. The cleaning holes 6 penetrate the side wall of the cleaning pipe 5. During cleaning, the water in the cleaning pipe 5 flows through the cleaning holes 6 to the outside of the cleaning pipe 5, which is convenient for cleaning the stones. At the same time, by controlling the relative position between the two first cleaning plates 1, the angle between the second cleaning plate 2 and the first cleaning plate 1 can be adjusted. When the second cleaning plate 2 is 90 degrees to the first cleaning plate 1, the cleaning pipe 5 is folded at the position where the first cleaning plate 1 and the second cleaning plate 2 are rotated, and the water in the cleaning pipe 5 will not flow out from this part, which is suitable for cleaning stones of smaller loading vehicles and will not waste water resources; when the angle between the second cleaning plate 2 and the first cleaning plate 1 is greater than 90 degrees, the two second cleaning plates 2 are separated, and water flows through the cleaning pipe 5 in the second cleaning plate 2 and transfers the water, which is suitable for the unloading process of stones of larger loading vehicles.

[0048] Reference Figure 1 、 Figure 3 and Figure 4 A support plate 7 is placed on the ground, which can be fixed to the ground by bolts. A support tube 8 is provided on the support plate 7, which can slide on the support plate 7. In this embodiment, there are four support tubes 8. A plurality of support rods 9 are fixed to the bottom of the first cleaning plate 1 in an integrated manner. The number of support rods 9 corresponds to the number of support tubes 8. In this embodiment, there are four support rods 9, which are passed through the support tube 8 and are slidably connected to the inner wall of the support tube 8. The support rod 9 can slide along the axis direction of the support tube 8, and the support tube 8 slides on the support plate 7 in a direction perpendicular to its own axis. The relative position between the two first cleaning plates 1 can be adjusted by adjusting the position of the support tube 8, so that it can be suitable for loading vehicles of different sizes.

[0049] Reference Figure 1 、 Figure 5 and Figure 6The bottom of the support rod 9 is connected to the runner 10 by a rotating shaft, and a control groove is provided on the side wall of the support cylinder 8, and the length direction of the control groove is parallel to the axis direction of the support cylinder 8. At the same time, the control groove penetrates the support cylinder 8 along the thickness direction of the side wall of the support cylinder 8. At the same time, a driving rod 11 is passed through the control groove, and a driving groove 12 is provided at the end of the driving rod 11. The runner 10 is passed through the driving groove 12. When the driving rod 11 rotates, the position of the runner 10 in the driving groove 12 can be adjusted. At the same time, the inner side wall of the control groove plays a limiting role for the runner 10, which is convenient for adjusting the position of the support rod 9 in the support cylinder 8, thereby adjusting the height of the first cleaning plate 1; a support groove 13 is provided at the bottom of the support plate 7, and two starting rods 14 are passed through the support groove 13, and the axis directions of the two starting rods 14 are parallel to each other, and the axis directions of the two starting rods 14 are perpendicular to the length direction of the control rod 21; the end of the starting rod 14 is slidably connected to a fixing part, and the fixing part at the end of the starting rod 14 is fixed together with the end of the driving rod 11 by bolts. The cross-sectional shape of the fixed portion is rectangular, and the rotation of the starting rod 14 can drive the driving rod 11 to rotate synchronously. The side wall of the starting rod 14 is fixed with a starting gear 15 by bolts. The starting gear 15 and the starting rod 14 are coaxially arranged. A starting motor 16 is fixed inside the support groove 13 by bolts. The starting motor 16 is keyed to a starting screw rod 17 at the rotating shaft of the starting motor 16. The axial direction of the starting screw rod 17 is perpendicular to the axial direction of the starting rod 14. At the same time, the starting screw rod 17 is meshed with the two starting gears 15. The starting motor 16 drives the starting screw rod 17 to rotate, which can drive the two starting gears 15 to rotate, thereby driving the starting rod 14 to rotate, so as to make the driving rod 11 rotate and control the position of the support rod 9 in the support tube 8. The starting motor 16 is a servo motor, which can stop rotating when the control rod 21 is driven to the desired position. At the same time, a matching protective tube is provided. The protective tube is C-shaped. After the fixed portion is extended, the protective tube is sleeved on the fixed portion and fixed to the ground by bolts, which enhances the possibility of damage to the fixed portion.

[0050] Reference Figure 1 and Figure 4 , an adjustment groove 18 is provided on the support plate 7, and a plurality of positioning grooves 19 are provided on the inner wall of the adjustment groove 18. The plurality of positioning grooves 19 are evenly distributed along the length direction of the inner wall of the adjustment groove 18. A positioning block 20 is slidingly provided on the side wall of the support cylinder 8, and a positioning spring is provided inside the support cylinder 8 for pushing the positioning block 20 away from the support cylinder 8. The positioning block 20 can slide radially along the support cylinder 8 on the support cylinder 8, and there will be no contact between the positioning block 20 and the support rod 9, thereby reducing the possibility of interference between the positioning block 20 and the support rod 9. By controlling the positioning block 20 to pass through different positioning grooves 19, the position of the support cylinder 8 is limited, which facilitates the adjustment of the angle between the first cleaning plate 1 and the second cleaning plate 2; thereby facilitating the adaptation of loading vehicles with different widths.

[0051] Reference Figure 1 and Figure 7 The two support rods 9 placed on the rotating shaft of the second cleaning plate 2 are fixed with a control rod 21 by bolts. The control rod 21 is horizontally arranged, and a control groove is opened on the control rod 21, which penetrates the control rod 21 in a direction perpendicular to the length of the control rod 21. The inner side wall of the control groove is rotated by a flip axis to provide a control plate 22. The control plate 22 has two pieces and is respectively placed at both ends of the length direction of the control rod 21. The rotating shaft of the control plate 22 and the inner side wall of the control groove is placed in the direction close to the support rod 9. The opposite ends of the two control plates 22 are rotatably connected with a pressing rod 23 by a rotating shaft. The length direction of the pressing rod 23 is parallel to the length direction of the control rod 21, and the side wall of the pressing rod 23 is fixed with a limiting rod 24 in an integrally formed manner. The axis direction of the limiting rod 24 is perpendicular to the axis direction of the pressing rod 23. At the same time, the limiting rod 24 is passed through the control rod 21 and can slide in the control rod 21 in a direction perpendicular to the control rod 21, thereby reducing the displacement of the position of the pressing rod 23. The cam 23 is pressed against the stop 20, and the cam 23 is pressed against the stop 20, so that the cam 23 is in contact with the stop 20.

[0052] Reference Figure 1 and Figure 8, one side wall of the first cleaning plate 1 is fixed with a first cooperative rod 25 by bolts, and the other side wall of the first cleaning plate 1 is fixed with a second cooperative rod 26 by bolts. The first cooperative rod 25 is "U"-shaped, and a U-shaped tube 27 is provided between the first cooperative rod 25 and the second cooperative rod 26. The first cooperative rod 25 and the second cooperative rod 26 are both passed through the U-shaped tube 27. The ends of the first cooperative rod 25 and the second cooperative rod 26 placed in the U-shaped tube 27 are fixed with a blocking block 28 in an integrally formed manner. The side wall of the blocking block 28 is fixed with a sealing ring 29 by bonding. The sealing ring 29 is made of rubber, and there is a gap between the sealing ring 29 and the inner wall of the U-shaped tube 27. Interference fit, and at the same time, the U-shaped tube 27 is filled with liquid medium. When the second cleaning plate 2 is 90 degrees to the first cleaning plate 1, the blocking block 28 at the end of the second cooperative rod 26 is placed in the U-shaped tube 27 near the bending part of the U-shaped tube 27, and the blocking block 28 at the end of the first cooperative rod 25 is placed in the U-shaped tube 27 near the end of the U-shaped tube 27. When the first cleaning plate 1 moves, due to the presence of liquid medium in the U-shaped tube 27, the blocking block 28 near the end of the U-shaped tube 27 moves toward the bending part of the U-shaped tube 27, which can push the blocking block 28 near the bending part of the U-shaped tube 27 to move toward the end of the U-shaped tube 27, so as to make the two first cleaning plates 1 move synchronously.

[0053] In a second aspect, this embodiment further discloses a stone washing method applicable to the above-mentioned self-compacting rockfill washing device, comprising the following steps:

[0054] a. Start the motor 16, drive the control rod 21 to rotate, and adjust the height of the support rod 9;
