Description

Technical Field

[0001] The utility model relates to the technical field of road subgrade compaction, in particular to a road subgrade compaction device. Background Art

[0002] In road construction, roadbed compaction is a very important step, which can increase the stability and bearing capacity of the road and improve the durability and service life of the road.

[0003] The publication number is CN219690251U, and the Chinese patent discloses a road bed compaction equipment. The device realizes the transmission of the half gear to the gear through the first motor, and realizes the up and down movement of the compaction hammer with the use of the spring. The compaction hammer realizes the effect of compacting the road bed by continuously colliding with the road bed surface. At the same time, the dust generated by the compaction hammer during compaction can be transferred to the filter box through the suction tube through the dust suction head, and filtered through the filter plate. At the same time, the filtered air is discharged through the filter dustproof net, thereby reducing the inhalation of dust by the staff, improving the working environment, and ensuring the practicality of the device.

[0004] With respect to the above-mentioned related technologies, the device has some shortcomings. In actual use, as the dust suction component sucks in more and more dust, the filter plate gradually accumulates dust, making the permeability smaller, thereby affecting the dust suction effect. In order to clean the filter plate, the device needs to be shut down, and two filter plates need to be cleaned and replaced at the same time, which increases the difficulty of the staff and reduces the efficiency of the device. Therefore, it is necessary to provide a roadbed compaction device to solve the above technical problems. Utility Model Content

[0027] See also Figure 1-4 , an embodiment provided by the utility model:

[0028] A roadbed compaction device, comprising:

[0029] A base plate 1, an operation box 8 is fixedly installed on the top of the base plate 1, a tamping mechanism is arranged inside the operation box 8, a handle 16 is fixedly installed on the top of the base plate 1 located on one side of the operation box 8, a filter box 28 is fixedly installed on the top of the operation box 8, a pump body 10 is fixedly installed on the top of the filter box 28, and an input end of the pump body 10 passes through the top of the filter box 28 and extends to the top of the filter box 28, a mounting groove 19 is opened on one side of the filter box 28, and the number of the mounting grooves 19 is two;

[0030] The filter box 28 is slidably connected with the filter plate 9 through the installation groove 19, and a positioning plate 20 is fixedly installed on one side of the filter plate 9. The top of the base plate 1 is located on the outside of the operation box 8 and a dust suction pipe 7 is fixedly installed and inserted therein. There are four dust suction pipes 7, and the top ends of the four dust suction pipes 7 all penetrate the outer surface of the filter box 28 and extend to the bottom of the inside of the filter box 28. A dust hood 3 is fixedly installed on the bottom end of the dust suction pipe 7.

[0031] One side of the filter box 28 is provided with a slide groove 26 below the two mounting grooves 19, and a slide rod 27 is fixedly installed inside the slide groove 26. A positioning block 24 is sleeved on the outer wall of the slide rod 27, and the positioning block 24 is slidably connected to the slide groove 26. A second spring 25 is sleeved on the outer wall of the slide rod 27 at the bottom of the positioning block 24, and a locking plate 22 is fixedly installed on one side of the positioning block 24. A positioning groove 21 is provided at the bottom of the positioning plate 20, and the positioning groove 21 is clamped with the locking plate 22. A handle 23 is fixedly installed at the bottom of one side of the locking plate 22, which improves the stability of the filter plate 9 when used inside the filter box 28. At the same time, the fixed limiting structure of the filter plate 9 is simple, easy to operate, and does not affect the rapid assembly and disassembly of the filter plate 9.

[0032] In one of the embodiments, a sliding hole matched with the sliding rod 27 is opened on the top of the positioning block 24, and the positioning block 24 is slidably connected to the sliding rod 27 through the sliding hole opened on the top thereof. Accurate positioning and alignment can be achieved through the sliding connection between the sliding rod 27 and the positioning block 24. This connection method can ensure that the positioning block 24 maintains a stable position during the sliding process, thereby achieving an accurate positioning function.

[0033] In one preferred embodiment, the tamping mechanism includes a rotating shaft 12, and the rotating shaft 12 is rotatably installed above the inside of the operating box 8, a first motor 13 is fixedly installed on one side of the operating box 8, and the driving end of the first motor 13 passes through one side of the operating box 8 and extends to the inside of the operating box 8 and is fixedly connected to one end of the rotating shaft 12, a cam plate 11 is fixedly installed on the outer wall of the rotating shaft 12, and the number of the cam plates 11 is two, and symmetrically distributed fixed blocks 14 are fixedly installed on both sides of the inside of the operating box 8, and the number of the fixed blocks 14 is Four, four fixed blocks 14 are divided into two groups, each group of fixed blocks 14 is fixedly installed with a limit rod 5, the outer walls of the two limit rods 5 are sleeved with movable blocks 15, a mounting plate 6 is fixedly installed between the two movable blocks 15, and the bottom of the mounting plate 6 is fixedly installed with symmetrically distributed mounting arms 17, and the bottom end of the mounting arm 17 is fixedly installed with a tamping hammer 18. The outer wall of the limit rod 5 is located at the lower side of the bottom of the movable block 15 and is sleeved with a first spring 4, so that the tamping hammer 18 moves up and down to collide with the roadbed surface, thereby achieving the effect of compacting the roadbed.

[0034] In one embodiment, a sliding hole adapted to the limiting rod 5 is provided on the top of the movable block 15 , and the movable block 15 is slidably connected to the limiting rod 5 through the sliding hole provided on the top of the movable block 15 .

[0035] In one preferred embodiment, symmetrically distributed universal wheels 2 are fixedly mounted on both sides of the bottom of the base plate 1. The universal wheels have multi-directional rolling capabilities and can move freely in all directions. The symmetrically distributed universal wheels installed on the device can provide better balance and stability, allowing the device to be easily moved.

[0036] The working principle of the utility model is as follows: the electrical components appearing in the present application are all externally connected to a power source and a control switch when in use, and the parts not involved in the device are the same as the prior art or can be implemented by the prior art. When the device is in use, the staff pushes the device by holding the handle 16, and pushes the device to move through the rolling contact between the universal wheel 2 and the road. In the process of pushing the device forward on the road, the first motor 13 is controlled by the switch to start working, and the driving end of the first motor 13 drives the rotating shaft 12 to rotate, and the rotation of the rotating shaft 12 drives the cam plate 11 to rotate. When the cam plate 11 is far away When the side away from the center approaches the mounting plate 6, a downward pressure will be generated on the mounting plate 6, so that the mounting plate 6 drives the movable block 15 to slide downward on the outer wall of the limit rod 5 and squeeze the first spring 4. The movement of the mounting plate 6 drives the tamping hammer 18 to move through the mounting arm 17. When the side close to the center of the cam plate 11 approaches the mounting plate 6, the downward thrust on the mounting plate 6 will be lost. At this time, under the elastic action of the first spring 4, the mounting plate 6 will be driven to reset upward through the movable block 15, thereby driving the tamping hammer 18 to reset. Therefore, under the drive of the first motor 13, the tamping hammer 18 moves up and down. The roadbed surface is collided to achieve the effect of compacting the roadbed. During the compaction process of the roadbed, the pump body 10 is controlled to start working. After the pump body 10 is started, a suction force is generated inside the filter box 28. Through the passage formed by the filter box 28, the dust suction pipe 7 and the dust suction cover 3, the four dust suction covers 3 will simultaneously suck dust at four directions around the compaction mechanism when the roadbed is compacted, so as to avoid dust flying and being inhaled by the staff to the greatest extent. The dust sucked by the dust suction cover 3 will directly enter the interior of the filter box 28 and be filtered by the filter plate 9. The filtered air is discharged through the output end of the pump body 10. When the dust filtered on the filter plate 9 When a certain amount is reached and it needs to be cleaned, since there are two filter plates 9 inside the filter box 28, the lower filter plate 9 can be directly pulled out from the right side of the filter box 28. At this time, the upper filter plate 9 will continue to filter the inhaled dust. After the lower filter plate 9 is cleaned and replaced, it is installed again, thereby realizing the disassembly, cleaning and replacement of the filter plate 9 without stopping the machine. In addition, the dust inhaled by the four dust suction hoods 3 of the device is concentrated into the interior of the filter box 28. Therefore, only one filter plate 9 needs to be replaced each time, which greatly reduces the difficulty of cleaning and replacing the filter plate 9 for the staff and improves the efficiency of the device.

[0037] The filter plate 9 is installed from the right side of the filter box 28 into the interior of the filter box 28 by sliding and plugging. When the filter plate 9 is installed, the positioning plate 22 is directly inserted into the interior of the positioning groove 21 at the bottom of the positioning plate 20 on one side of the filter plate 9 through the elastic action of the second spring 25. The engagement between the positioning plate 22 and the positioning groove 21 will limit the positioning plate 20, so that the filter plate 9 is firmly fixed in the interior of the filter box 28 for use, ensuring the stability of the filter plate 9 during use. When the filter plate 9 needs to be disassembled and assembled, only the handle 23 needs to be gently pulled, and the movement of the handle 23 drives The locking plate 22 is disengaged from the interior of the positioning groove 21. At the same time, the movement of the locking plate 22 drives the positioning block 24 to slide downward on the outer wall of the slide rod 27 and squeeze the second spring 25. After the locking plate 22 is disengaged from the interior of the positioning groove 21, the positioning plate 20 can be easily pulled to remove the filter plate 9 from the interior of the filter box 28. Therefore, the locking plate 22 and the positioning groove 21 are limited, which improves the stability of the filter plate 9 when used in the filter box 28. At the same time, the fixed limiting structure of the filter plate 9 is simple and easy to operate, which does not affect the rapid assembly and disassembly of the filter plate 9, thereby improving the convenience of user use.

[0038] The above is only an embodiment of the utility model, and the common sense such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model. Any figure mark in the claims should not be regarded as limiting the claims involved.
