Description

Technical Field

[0001] This utility model relates to the field of compaction machines, and in particular to a compaction machine for civil engineering projects. Background Technology

[0002] A tamping machine is a type of civil engineering machinery used to compact the ground. A hydraulic tamping machine uses hydraulic control to move the tamping head up and down, and an auxiliary seat limits the range of the tamping head, allowing it to work more stably and compact the land.

[0003] When a common compactor is in operation, the tamping head moves vertically to impact and compact the ground. During the impact process, the tamping head generates a large amount of dust, which is scattered in the external environment, easily causing environmental pollution and obstructing the view of personnel, making it difficult for them to observe. Utility Model Content

[0004] The purpose of this utility model is to provide a compaction machine for civil engineering projects to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tamping machine for civil engineering, comprising a tamping machine body, wherein a hydraulic hammer head is provided on the front of the tamping machine body for performing tamping operations;

[0006] The bottom of the hydraulic hammer is equipped with a dustproof mechanism to clean up the dust generated during the compaction operation.

[0007] The dustproof mechanism includes a dust suction hood, which is slidably inserted into the bottom of the hydraulic hammer head. A corrugated pipe is fixedly connected to the top of the dust suction hood, and the top of the corrugated pipe is fixedly connected to the outer wall of the hydraulic hammer head. Connecting pipes are fixedly connected to both sides of the back of the corrugated pipe.

[0008] Both sides of the dust hood are equipped with movable mechanisms to ensure that the dust hood moves stably in the vertical direction.

[0009] Preferably, the movable mechanism includes a fixed block, a movable rod is fixedly connected to the upper surface of the fixed block, and a mounting block is slidably inserted through the top end of the movable rod.

[0010] Preferably, a pressing block is fixedly connected to the middle of the movable rod, and a compression spring is movably sleeved on the top of the movable rod, with the compression spring disposed between the pressing block and the mounting block.

[0011] Preferably, one side of the fixing block is fixedly connected to the side wall of the dust hood, one side of the mounting block is fixedly connected to the outer wall of the hydraulic hammer head, and a limiting block is fixedly connected to the top of the movable rod, with the limiting block positioned above the mounting block.

[0012] Preferably, a dust extraction fan is fixedly connected to both sides of the main body of the compactor, and the front of the dust extraction fan is fixedly inserted into one end of the connecting pipe.

[0013] Preferably, the corrugated pipe is movably connected to the bottom of the hydraulic hammer head, and the two connecting pipes are arranged on both sides of the main body of the compactor.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] This utility model utilizes a combination of a dust collection hood, a corrugated pipe, and a connecting pipe. The dust collection hood is moved downwards by a hydraulic hammer. When the hydraulic hammer impacts the ground, the bottom of the dust collection hood contacts the ground. The operation of the dust collection fan draws in the airflow inside the dust collection hood and the corrugated pipe through the connecting pipe, thus collecting the dust generated during compaction, preventing the dust from scattering, and reducing the impact of dust on the working environment.

[0016] This invention utilizes a combination of a dust hood, a movable rod, a squeezing block, and a compression spring. When the bottom of the dust hood contacts the ground, it moves upward, causing the movable rod and the squeezing block to move upward together. This causes the squeezing block to compress and deform the compression spring, and the elasticity of the compression spring pushes the squeezing block and the movable rod downward, ensuring that the bottom of the dust hood is in stable contact with the ground.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1-3 The shown is a tamping machine for civil engineering, including a tamping machine body 1. The tamping machine body 1 is used to drive the hydraulic hammer head 2 to move. The hydraulic hammer head 2 is provided on the front of the tamping machine body 1 for tamping operations. The ground is tamped by impacting it with the hydraulic hammer head 2.

[0023] The bottom of the hydraulic hammer head 2 is equipped with a dustproof mechanism 3, which is used to clean up the dust generated during the compaction operation and prevent the dust from spreading.

[0024] The dustproof mechanism 3 includes a dust suction hood 31, which moves together with the hydraulic hammer head 2 to suck up the generated dust. The dust suction hood 31 is slidably connected to the bottom of the hydraulic hammer head 2. The dust suction hood 31 can move on the hydraulic hammer head 2, so that the bottom ends of the dust suction hood 31 and the hydraulic hammer head 2 are in stable contact with the ground. A corrugated pipe 32 is fixedly connected to the top of the dust suction hood 31. The corrugated pipe 32 is made of elastic material and can deform to a certain extent. It is used to connect the dust suction hood 31 to ensure that the dust suction hood 31 can stably suck up the dust. The top of the corrugated pipe 32 is fixedly connected to the outer wall of the hydraulic hammer head 2. Connecting pipes 33 are fixedly connected to both sides of the back of the corrugated pipe 32. The connecting pipes 33 are made of rubber hoses. The dust suction hood 31 is connected to the dust suction fan 6 through the connecting pipes 33 to collect and discharge the dust.

[0025] Movable mechanisms 4 are provided on both sides of the dust hood 31 to ensure that the dust hood 31 moves stably in the vertical direction and that the bottom of the dust hood 31 is in stable contact with the ground.

[0026] The movable mechanism 4 includes a fixed block 41, which is used to install the movable rod 42 to ensure the stable movement of the movable rod 42. The movable rod 42 is fixedly connected to the upper surface of the fixed block 41. The movable rod 42 is used to connect to the dust hood 31. The dust hood 31 drives the movable rod 42 to move together, so that the dust hood 31 moves stably in the vertical direction. The top end of the movable rod 42 is slidably connected to the mounting block 43. The movable rod 42 slides stably on the fixed block 41. When the bottom end of the hydraulic hammer head 2 contacts the ground, the dust hood 31 moves in the vertical direction.

[0027] A squeezing block 44 is fixedly connected to the middle of the movable rod 42. The squeezing block 44 moves together with the movable rod 42 to squeeze the compression spring 45. The compression spring 45 is movably sleeved on the top of the movable rod 42. The compression spring 45 is located between the squeezing block 44 and the mounting block 43. When the bottom of the dust hood 31 contacts the ground, the dust hood 31 moves upward, causing the movable rod 42 and the squeezing block 44 to move upward together. This causes the squeezing block 44 to compress and deform the compression spring 45. The elasticity of the compression spring 45 is used to push the squeezing block 44 and the movable rod 42 downward to ensure that the bottom of the dust hood 31 is in stable contact with the ground.

[0028] One side of the fixed block 41 is fixedly connected to the side wall of the dust hood 31, one side of the mounting block 43 is fixedly connected to the outer wall of one side of the hydraulic hammer head 2, and the top of the movable rod 42 is fixedly connected to the limit block 5. The limit block 5 is set above the mounting block 43. The limit block 5 moves together with the movable rod 42 to limit the movement of the movable rod 42 and prevent the movable rod 42 from separating from the mounting block 43.

[0029] Dust-collecting fans 6 are fixedly connected to both sides of the main body 1 of the tamping machine. The dust-collecting fans 6 are electrically connected to an external power supply through an external switch. The front of the dust-collecting fans 6 is fixedly inserted into one end of the connecting pipe 33. Through the operation of the dust-collecting fans 6, the airflow inside the dust-collecting hood 31 and the corrugated pipe 32 is sucked up through the connecting pipe 33 to suck up the dust generated during tamping.

[0030] The corrugated pipe 32 is movably connected to the bottom of the hydraulic hammer head 2, and two connecting pipes 33 are set on both sides of the main body 1 of the compactor.

[0031] The working principle of this utility model is as follows: The hydraulic hammer head 2 drives the dust collection hood 31 to move downward together. When the hydraulic hammer head 2 hits the ground, the bottom end of the dust collection hood 31 contacts the ground. The operation of the dust collection fan 6 draws in the airflow inside the dust collection hood 31 and the corrugated pipe 32 through the connecting pipe 33 to collect the dust generated by compaction. At the same time, when the bottom end of the dust collection hood 31 contacts the ground, the dust collection hood 31 moves upward, driving the movable rod 42 and the squeezing block 44 to move upward together. This causes the squeezing block 44 to compress and deform the compression spring 45. The elasticity of the compression spring 45 pushes the squeezing block 44 and the movable rod 42 downward, ensuring that the bottom end of the dust collection hood 31 is in stable contact with the ground.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
