A treatment device and treatment method for soil used in the subgrade of highway engineering

Abstract

The present invention discloses a treatment device and a treatment method for soil used in the subgrade of highway engineering, belonging to the technical field of treatment devices for soil used in subgrade. Among them, the treatment device for soil used in the subgrade of highway engineering includes a support plate and a cylinder body arranged on the support plate. A transverse plate is rotatably installed inside the cylinder body. Two groups of crushing plates are installed at the bottom of the transverse plate. The crushing plates can rotate relative to the transverse plate. Two groups of driving components are arranged at the top of the transverse plate; the plane structure composed of multiple crushing plates in one of the groups can prompt the incompletely crushed soil blocks to move to the baffle and leak out through the baffle. The guiding plate can gather the leaked soil blocks towards the center of the transverse plate. When the next group of crushing plates passes by, the leaked soil blocks can be crushed. Since the leaked soil blocks are near the end of the transverse plate, and the crushing plates near the end at the transverse plate have a relatively large linear velocity, the soil blocks can be fully crushed.

Description

Technical Field

[0001] The present invention relates to the technical field of soil treatment devices for roadbeds, and particularly relates to a soil treatment device and method for roadbeds in highway engineering. Background Art

[0002] During the construction of highways, it is necessary to carry out filling operations on highway roadbeds. The bottom layer of highway roadbeds is a soil layer. When filling highway roadbeds, it is necessary to level the soil layer. However, in actual highway roadbed filling operations, the soil layer often has the problem of soil caking and needs to be broken.

[0003] Chinese Patent CN218596876U discloses a soil crushing device for roadbed filling. By extending the electric hydraulic cylinder, the electric hydraulic cylinder drives the roadbed positioning cone to extend and reach inside the roadbed soil to fix the position of the device main body. Thus, the position of the crushing paddle during soil crushing work can be more stable, improving the working effect, protecting the safety of the structure, having good adaptability, being beneficial to increasing the working range, and facilitating long-term work.

[0004] The above device crushes soil blocks through the provided rotating plate and crushing paddles. However, since the crushing paddles are mainly distributed at the outer edge of the rotating plate, it is difficult to process the soil blocks near the center of the rotating plate through the crushing paddles. In summary, there is still room for improvement in the above device.

[0005] Therefore, it is necessary to provide a soil treatment device and method for roadbeds in highway engineering to solve the above technical problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a soil treatment device and method for roadbeds in highway engineering to solve the problem that the existing device crushes soil blocks through the provided rotating plate and crushing paddles, but since the crushing paddles are mainly distributed at the outer edge of the rotating plate, it is difficult to process the soil blocks near the center of the rotating plate as mentioned in the above background art.

[0007] Based on the above idea, the present invention provides the following technical solution: A soil treatment device for roadbeds in highway engineering includes a support plate and a cylinder body arranged on the support plate. A transverse plate is rotatably installed inside the cylinder body. Two groups of crushing plates are installed at the bottom of the transverse plate. The crushing plates can rotate relative to the transverse plate. Two groups of driving components are arranged at the top of the transverse plate. The two groups of driving components are symmetrically arranged about the center of the transverse plate. The driving components can drive the crushing plates below the transverse plate to rotate;

[0008] A baffle is provided at a position on the bottom surface of the horizontal plate and near the end. The baffle is elastically connected to the horizontal plate, and the baffle can move relative to the horizontal plate along its length direction. When a plurality of crushing plates in one group are driven by the driving component to rotate to a coplanar state, during the rotation of the horizontal plate, the soil blocks on one side of the crushing plates can be thrown to the baffle along the plane formed by the plurality of crushing plates, and then leak out through one side of the baffle, so that the other group of crushing plates can crush the leaked soil blocks during the rotation along with the horizontal plate.

[0009] As a further solution of the present invention: a fixing plate is fixedly connected to the top surface of the crushing plate, and a vertical shaft is fixedly arranged on the top surface of the fixing plate. The vertical shaft passes through the horizontal plate and is rotatably connected to the horizontal plate. A gear is fixedly sleeved at one end of the vertical shaft passing through the horizontal plate.

[0010] As a further solution of the present invention: the driving component includes a rack sliding on the top surface of the horizontal plate and meshing with the gear. The number of the racks is set to two, and the two racks are respectively matched with the gears above the two groups of crushing plates.

[0011] As a further solution of the present invention: at least one positioning block is fixedly arranged on the outer side surface of the rack. A positioning groove is opened on the top surface of the horizontal plate along its length direction. The positioning block slides in the positioning groove. A guiding rod is fixedly installed on the top surface of the positioning block. A cover plate is fixedly installed on the top surface of the cylinder body. A through groove is opened at the center of the cover plate, and a cam is arranged at the through groove. A guiding channel for the guiding rod to slide is formed between the outer side wall of the cam and the inner wall of the through groove. The guiding channel has a first guiding groove and a second guiding groove, and the first guiding groove and the second guiding groove are connected by an inclined groove. During the process that the guiding rod moves along the inclined groove to the second guiding groove, a plurality of crushing plates in one group can rotate to a coplanar state.

[0012] As a further solution of the present invention: a slider is fixedly connected to the top surface of the baffle. A sliding groove matched with the slider is opened on the horizontal plate along its length direction. A protrusion is fixedly installed on one side of the slider close to the rack. One end of the rack close to the slider extends to the protrusion.

[0013] As a further solution of the present invention: an arc-shaped guiding plate is fixedly installed on one side of the baffle.

[0014] As a further solution of the present invention: the cross sections of the positioning block and the positioning groove are both arranged in a T shape.

[0015] As a further solution of the present invention: the overall length of the baffle is greater than the overall length of the crushing plate.

[0016] As a further solution of the present invention: the center of the horizontal plate and the center of the cylinder body are on the same straight line.

[0017] A method of treating soil for subgrade of highway engineering using the above-mentioned treatment device includes the following steps: driving two groups of crushing plates to rotate through a cross plate, and using the crushing plates to crush soil blocks; when one group of crushing plates rotates to a coplanar state, the incompletely crushed soil blocks can move along the plane formed by multiple crushing plates to the baffle and leak out through the baffle; the other group of crushing plates can crush the leaked soil blocks.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the plane structure formed by multiple crushing plates in one group can promote the movement of incompletely crushed soil blocks to the baffle and leak out through the baffle, and the guide plate can gather the leaked soil blocks towards the center of the cross plate. When the next group of crushing plates passes by, the leaked soil blocks can be crushed. Since the leaked soil blocks are near the end of the cross plate, and the crushing plates near the end at the cross plate have a relatively large linear velocity, the soil blocks can be fully crushed.

[0031] As Figures 1 - 10 shown, a processing device and a processing method for soil used in the subgrade of highway engineering include a support plate 8 and a cylinder 7 arranged on the support plate 8. The cylinder 7 passes through the support plate 8 and is fixedly connected thereto. A horizontal plate 13 is rotatably installed inside the cylinder 7. The center of the horizontal plate 13 and the center of the cylinder 7 are on the same straight line. Combining Figure 2 shown, two groups of crushing plates 14 are installed at the bottom of the horizontal plate 13. The crushing plates 14 can rotate relative to the horizontal plate 13. Two groups of driving components are arranged on the top of the horizontal plate 13. The two groups of driving components are symmetrically arranged about the center of the horizontal plate 13. The driving components can drive the crushing plates 14 below the horizontal plate 13 to rotate.

[0032] Furthermore, a baffle 17 is arranged at the bottom surface of the horizontal plate 13 and near the end. The baffle 17 is elastically connected to the horizontal plate 13, and the baffle 17 can move relative to the horizontal plate 13 along its length direction. Combining Figure 6 shown, the overall length of the baffle 17 is greater than the overall length of the crushing plate 14.

[0033] During actual use, when a group of multiple crushing plates 14 are driven by the driving components to rotate to a coplanar state, during the rotation of the horizontal plate 13, the soil blocks on one side of the crushing plates 14 can be thrown to the baffle 17 along the plane formed by the multiple crushing plates 14, and then leak out through one side of the baffle 17, so that the other group of crushing plates 14 can crush the leaked soil blocks during the rotation along with the horizontal plate 13.

[0034] As Figures 1 - 10 shown, a fixed plate 24 is fixedly connected to the top surface of the crushing plate 14, and a vertical shaft 25 is fixedly arranged on the top surface of the fixed plate 24. The vertical shaft 25 passes through the horizontal plate 13 and is rotatably connected thereto through a bearing. A gear 19 is fixedly sleeved on one end of the vertical shaft 25 passing through the horizontal plate 13.

[0035] The above driving assembly includes a rack 20 that slides on the top surface of the cross plate 13 and meshes with the gear 19. The number of racks 20 is set to two. By cooperating the two racks 20 with the gears 19 above the two groups of crushing plates 14 respectively, the two racks 20 are symmetrically arranged about the center of the cross plate 13;

[0036] Further, at least one positioning block 21 is fixed on the outer side surface of the rack 20, and a positioning groove is formed along the length direction of the top surface of the cross plate 13, so that the positioning block 21 slides in the positioning groove, and the cross sections of the positioning block 21 and the positioning groove are both set to be T-shaped. A guiding rod 16 is fixedly installed on the top surface of the positioning block 21. A cover plate 4 is fixedly installed on the top surface of the cylinder body 7 through bolts. A through groove is formed at the center of the cover plate 4, and a cam 3 is arranged at the through groove. A guiding channel 5 for the guiding rod 16 to slide is formed between the outer side wall of the cam 3 and the inner wall of the through groove. Specifically, as shown in Figure 4 shown, the guiding channel 5 has a first guiding groove 503 with a smaller diameter and a second guiding groove 501 with a larger diameter, and the first guiding groove 503 is connected to the second guiding groove 501 through an inclined groove 502. Referring to Figures 1 - 5 shown, when the guiding rod 16 rotates along with the cross plate 13, the guiding rod 16 can move along the track of the guiding channel 5. During the process that the guiding rod 16 moves along the inclined groove 502 to the second guiding groove 501, through the limiting of the inner wall of the inclined groove 502 on the guiding rod 16, the guiding rod 16 can drive the positioning block 21 and the rack 20 to move, and then drive the crushing plate 14 to rotate through the meshing of the rack 20 and the gear 19, so that multiple crushing plates 14 in one group can rotate to a coplanar state.

[0037] In order to increase the distance between the baffle 17 and the adjacent crushing plate 14, a slider 18 is fixedly connected to the top surface of the baffle 17 in this solution, and a sliding groove that slidably cooperates with the slider 18 is formed along the length direction of the cross plate 13. A protrusion 1801 is fixedly installed on one side of the slider 18 close to the rack 20, and one end of the rack 20 close to the slider 18 extends to the protrusion 1801. When the rack 20 is driven to slide by the guiding rod 16, the rack 20 can squeeze the protrusion 1801 to move, and then drive the baffle 17 to move outward along the length direction of the cross plate 13, which is beneficial to increasing the distance between the baffle 17 and an adjacent crushing plate 14, so that the soil blocks can leak out from between the baffle 17 and the crushing plate 14. An arc-shaped guiding plate 15 is fixedly installed on one side of the baffle 17. Referring to Figure 3 shown, both the baffle 17 and the guiding plate 15 are symmetrically arranged about the center of the cross plate 13.

[0038] During actual use, the equipment is pushed to the corresponding position, and the cross plate 13 is driven to rotate by an external power unit. In the initial state, the crushing plate 14 is in the state as shown in Figure 5The state shown (i.e., the projection of the crushing plate 14 on the cross plate 13 is perpendicular to the length direction of the cross plate 13). When the cross plate 13 drives the crushing plate 14 to rotate synchronously, the soil blocks can be crushed by the crushing plate 14. Since multiple crushing plates 14 are linearly arrayed along the length of the cross plate 13, the linear velocity of the crushing plate 14 near the center position of the cross plate 13 is relatively small. Therefore, some soil blocks are not completely crushed and stay near the center of the cross plate 13. And the guide rod 16 in this solution can move along the guide channel 5. Specifically, when the guide rod 16 rotates inside the first guide groove 503, the crushing plate 14 is in the state as Figure 5 shown. In this state, it is beneficial to crush the soil blocks through the crushing plate 14;

[0039] When one of the guide rods 16 passes through the first guide groove 503 and enters the second guide groove 501 through the inclined groove 502, the limit of the guide rod 16 by the inclined groove 502 can drive the rack 20 to move outward relative to the cross plate 13. During this process, the rotation of the crushing plate 14 can be driven by the meshing of the rack 20 and the gear 19, so that multiple crushing plates 14 in one group can rotate to a coplanar state. At this time, the other guide rod 16 is at the first guide groove 503, so that multiple crushing plates 14 in the other group are still in the initial state. The states of the two groups of crushing plates 14 can be specifically referred to Figure 6 shown. When the rack 20 moves outward relative to the cross plate 13, the rack 20 can drive the protrusion 1801 to move, and then drive the slider 18 and the baffle 17 to move outward relative to the cross plate 13, so that the distance between the baffle 17 and an adjacent crushing plate 14 increases. During the process of the guide rod 16 sliding along the second guide groove 501, multiple crushing plates 14 in the coplanar state can maintain the coplanar state. At this time, when the cross plate 13 drives multiple crushing plates 14 in the coplanar state to rotate, the incompletely crushed soil blocks can move along the plane formed by multiple crushing plates 14 towards the direction close to the baffle 17. When the soil blocks move to the baffle 17, they can leak out through the gap between the baffle 17 and the crushing plate 14. Through the arranged guide plate 15, the leaked soil blocks can be gathered towards the center position of the cross plate 13, so that the other group of crushing plates 14 can crush the leaked soil blocks during the moving process. Repeat the above process. The plane structure formed by multiple crushing plates 14 in one group can promote the incompletely crushed soil blocks to move to the baffle 17 and leak out through the baffle 17. The guide plate 15 can gather the leaked soil blocks towards the center direction of the cross plate 13, and the next group of crushing plates 14 can crush the leaked soil blocks when passing by. Since the leaked soil blocks are near the end of the cross plate 13, and the crushing plate 14 near the end of the cross plate 13 has a relatively large linear velocity, the soil blocks can be fully crushed.

[0040] AsFigures 1 - 10 As shown, rollers are installed at the four corners of the bottom of the support plate 8, and a push rod 1 is fixedly installed on the top of the support plate 8. The push rod 1 can push the device to move, and when the push rod 1 is pressed down, the device can be tilted upward, so that the soil block is placed under the device. An annular dust baffle 12 is slidably sleeved on the outer side of the cylinder 7. The dust baffle 12 is located below the support plate 8. Specifically, a protrusion 1201 is fixedly installed on the inner wall of the dust baffle 12, and a protrusion 1201 is opened on the outer wall of the cylinder 7. 201 slidingly cooperates with the strip groove, the inner side of the push rod 1 is slidably equipped with a pull rod 11, and the pull rod 11 is elastically matched with the push rod 1. Specifically, a rectangular groove 101 is opened at the inner wall of the push rod 1, and a guide block slidingly cooperates with the rectangular groove 101 is fixedly arranged at the end of the pull rod 11, and a spring is fixedly arranged between the guide block and the end surface of the rectangular groove 101, a pull rope 2 is fixedly arranged between the top surface of the dust baffle 12 and the pull rod 11, and vertical rods 9 are fixedly installed on both sides of the top surface of the support plate 8. Figure 1 As shown, the pull rope 2 passes through the support plate 8 and the vertical rod 9 and slides with them. Through this structure, when the staff releases the pull rod 11, the spring can push the pull rod 11 and then release the pull rope 2, so that the dust blocking plate 12 can fall, thereby preventing dust from overflowing during the process of breaking the soil blocks.

[0041] In order to drive the horizontal plate 13 to rotate, the present solution has a rotating shaft 22 fixedly installed on the top surface of the horizontal plate 13. The rotating shaft 22 passes through the cam 3 and is rotatably connected thereto. The centers of the first guide groove 503 and the second guide groove 501 are both on the axis of the rotating shaft 22. The above-mentioned power unit includes a motor, which is installed on the top of the support plate 8, and the motor and the rotating shaft 22 are connected through a transmission unit 10. Specifically, the transmission unit 10 can be a structure such as a belt or a chain.

[0042] The cam 3 and the cover plate 4 are fixedly connected via a plurality of U-shaped brackets 6 .

[0043] Combination Figures 3 - 7 As shown, the guide plate 15 is arc-shaped as a whole and is inclined toward the center of the horizontal plate 13. Figure 5 As shown, a cross bar 23 is fixedly installed in the slide groove, the cross bar 23 passes through the slider 18 and slides with it, and a spring is sleeved on the outer side of the cross bar 23, and the spring is fixed between the slider 18 and the end surface of the slide groove.

[0044] Reference Figure 9 As shown, the front and rear surfaces of the crushing plate 14 are both provided with chamfers, which is beneficial for crushing the soil clods.
