DETAILED DESCRIPTION

[0020] like Figure 1-Figure 10 As shown, a processing device and method for roadbed soil for highway engineering comprises 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 is in the same straight line with the center of the cylinder 7, and the cylinder 7 is connected to the support plate 8. Figure 2 As shown, two groups of crushing plates 14 are installed at the bottom of the horizontal plate 13, and 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, and the two groups of driving components are symmetrically arranged about the center of the horizontal plate 13. The crushing plates 14 under the horizontal plate 13 can be driven to rotate through the driving components; Furthermore, a baffle 17 is provided on the bottom surface of the transverse plate 13 and near the end thereof. The baffle 17 is elastically connected to the transverse plate 13 and can move relative to the transverse plate 13 along its length direction. Figure 6 As shown, the overall length of the baffle plate 17 is greater than the overall length of the crushing plate 14; In actual use, when one group of multiple crushing plates 14 is driven by the driving assembly to rotate to a coplanar state, during the rotation of the cross 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 of the cross plate 13.

[0021] like Figure 1-Figure 10 As shown, the top surface of the crushing plate 14 is fixedly connected to a fixing plate 24, and a vertical shaft 25 is fixedly arranged on the top surface of the fixing plate 24. The vertical shaft 25 passes through the horizontal plate 13 and is rotatably connected thereto through a bearing. One end of the vertical shaft 25 passing through the horizontal plate 13 is fixedly sleeved with a gear 19; The driving assembly includes a rack 20 that slides on the top surface of the horizontal plate 13 and meshes with the gear 19. The number of the racks 20 is set to two, and the two racks 20 are respectively matched with the gears 19 above the two groups of crushing plates 14. The two racks 20 are symmetrically arranged about the center of the horizontal plate 13; Further, at least one positioning block 21 is fixed on the outer side of the rack 20, and a positioning groove is provided on the top surface of the cross plate 13 along its length direction, 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 guide rod 16 is fixedly installed on the top surface of the positioning block 21, and a cover plate 4 is fixedly installed on the top surface of the cylinder 7 by bolts, a through groove is provided at the center of the cover plate 4, and a cam 3 is provided at the through groove, and a guide channel 5 for the guide rod 16 to slide is formed between the outer wall of the cam 3 and the inner wall of the through groove. Specifically, in combination with Figure 4 As shown, the guide channel 5 has a first guide groove 503 with a smaller diameter and a second guide groove 501 with a larger diameter, and the first guide groove 503 and the second guide groove 501 are connected by an inclined groove 502. Figure 1-Figure 5 As shown, when the guide rod 16 rotates with the cross plate 13, the guide rod 16 can move along the trajectory of the guide channel 5. In the process of the guide rod 16 moving along the inclined groove 502 to the second guide groove 501, the guide rod 16 is limited by the inner wall of the inclined groove 502, so that the guide 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 engagement of the rack 20 and the gear 19, so that a group of multiple crushing plates 14 can rotate to a coplanar state.

[0022] In order to increase the distance between the baffle 17 and its adjacent crushing plate 14, in this solution, a slider 18 is fixedly connected to the top surface of the baffle 17, and a slide groove slidably matched with the slider 18 is opened on the cross plate 13 along its length direction. A protrusion 1801 is fixedly installed on the side of the slider 18 close to the rack 20, and the 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 guide rod 16, the rack 20 can squeeze the protrusion 1801 to move, thereby driving the baffle 17 to move outward along the length direction of the cross plate 13, which is conducive 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 guide plate 15 is fixedly installed on one side of the baffle 17. Figure 3 As shown, the baffle plate 17 and the guide plate 15 are both symmetrically arranged about the center of the transverse plate 13 .

[0023] In actual use, the device is pushed to move to the corresponding position, and the external power unit is used to drive the horizontal plate 13 to rotate. In the initial state, the crushing plate 14 is in the following state: Figure 5In the state shown (i.e., the projection of the crushing plate 14 on the transverse plate 13 is in a state perpendicular to the length direction of the transverse plate 13), when the transverse plate 13 drives the crushing plate 14 to rotate synchronously, the soil blocks can be crushed by the crushing plate 14. Since the plurality of crushing plates 14 are distributed in a linear array along the length of the transverse plate 13, the linear speed of the crushing plate 14 near the center of the transverse plate 13 is relatively small. Therefore, some soil blocks are not completely crushed and remain near the center of the transverse plate 13. 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 a state as shown in FIG. Figure 5 The state shown, in this state, the crushing plate 14 is conducive to crushing the soil blocks; 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. In this process, the meshing of the rack 20 and the gear 19 can drive the crushing plate 14 to rotate, so that the multiple crushing plates 14 of one group can rotate to a coplanar state. At this time, the other guide rod 16 is in the first guide groove 503, so that the multiple crushing plates 14 of the other group are still in the initial state. The specific states of the two groups of crushing plates 14 can be referred to Figure 6 As shown, when the rack 20 moves outward relative to the cross plate 13, the protrusion 1801 can be driven to move by the rack 20, thereby driving 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. In the process of the guide rod 16 sliding along the second guide groove 501, the multiple crushing plates 14 in a coplanar state can maintain the coplanar state. At this time, in the process of the cross plate 13 driving the multiple crushing plates 14 in the coplanar state to rotate, the soil blocks that have not been completely crushed can move along the plane formed by the multiple crushing plates 14 toward the baffle 17. When the soil blocks move to the baffle 17, they can pass through the gap between the baffle 17 and the crushing plate 14. Leakage, through the set guide plate 15, can gather the leaked soil blocks toward the center of the horizontal plate 13, so that the leaked soil blocks can be broken during the movement of another group of crushing plates 14, repeat the above process, the planar structure composed of multiple crushing plates 14 in one group can prompt the incompletely broken 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 toward the center of the horizontal plate 13, and the next group of crushing plates 14 can crush the leaked soil blocks when passing by, because the leaked soil blocks are near the end of the horizontal plate 13, and the crushing plates 14 near the end of the horizontal plate 13 have a large linear velocity, so the soil blocks can be fully crushed.

[0024] like Figure 1-Figure 10As 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.

[0025] 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.

[0026] The cam 3 and the cover plate 4 are fixedly connected via a plurality of U-shaped brackets 6 .

[0027] Combination Figure 3-Figure 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.

[0028] Reference Fig. 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.
