Description

Technical Field

[0001] This application relates to the technical field of hydraulic compactors, and in particular to a compaction device for foundation backfilling. Background Technology

[0002] The compactor is mainly used in the construction of infrastructure such as highways, railways, ports, buildings, water conservancy, and municipal works, and is used to compact the roadbed of highways and railways.

[0003] Currently, hydraulic compactors work by using a hydraulic cylinder to lift the hammer to a certain height and then releasing it. The hammer then falls rapidly under the combined action of gravity and hydraulic energy, compacting the ground. However, existing hydraulic compactors release a large amount of dust during operation, polluting the working environment. Utility Model Content

[0004] To improve the practicality of compaction machines, this application provides a compaction device for foundation backfilling.

[0005] This application provides a compaction device for foundation earthwork backfilling, which adopts the following technical solution: A compaction device for foundation earthwork backfilling includes a compactor body, and further includes:

[0006] The dust suppression assembly includes a top plate and side plates. The top plate is horizontally positioned, and the compactor body is mounted on and fixedly connected to the top plate. The side plates are located below the top plate and are fitted onto the compactor body. There is a gap between the side plates and the compactor body. The side plates are telescopic structures that extend and retract in the vertical direction. The movable end of the side plate is fixedly connected to the top plate, and the bottom surface of the fixed end of the side plate is used to contact the ground.

[0007] A collection component is installed on the inner wall of the side panel and is used to collect dust that is close to itself;

[0008] The purging assembly is positioned opposite the collecting assembly. The purging assembly is used to spray gas, and the sprayed gas is used to blow dust in the side panel onto the collecting assembly.

[0009] By adopting the above technical solution, when the operator controls the tamping machine body to carry out tamping operations, the bottom surface of the fixed end of the side plate abuts against the ground, so that the side plate, the top plate, and the ground form a relatively independent dust suppression space. The dust generated during the tamping operation is confined within the dust suppression space, avoiding dust pollution to the working environment.

[0010] For dust in the dust suppression space, the operator can use the blowing component to blow the dust to the collection component, and the collection component will collect the dust, thereby improving the practicality of the compactor.

[0011] Optionally, the purging assembly includes a nozzle and a connecting pipe. The nozzle is fixedly connected to the side plate and several are arranged in the vertical direction. Several connecting pipes are arranged, and adjacent nozzles are interconnected through the connecting pipes.

[0012] The tamping machine body is equipped with an air supply component, which is used to supply gas to the nozzle.

[0013] By adopting the above technical solution, when collecting dust in the dust suppression space, the air supply component is activated, and the air supply component fills the nozzle with gas, so that the gas is sprayed out from the nozzle and flows towards the collection component.

[0014] As the gas flows, it carries dust from the air, allowing the dust in the dust suppression space to collect onto the collection components.

[0015] Optionally, the air supply assembly includes an air pump and an air supply pipe. One end of the air supply pipe is connected to a connecting pipe, and the other end is connected to the outside. The air supply pipe is fixedly connected to the compactor body. The air pump is installed on the air supply pipe and is fixedly mounted on the compactor body.

[0016] By adopting the above technical solution, when collecting dust in the dust suppression space, the air pump is started. The air pump fills the connecting pipe with air through the air supply pipe, so that the gas can be sprayed out through the nozzle, which facilitates the collection of dust in the dust suppression space.

[0017] Optionally, the collection component includes a vertically arranged dust collection screen, which is detachably and fixedly connected to the top plate.

[0018] By adopting the above technical solution, the gas sprayed through the nozzle blows the dust in the dust suppression space onto the dust collection net, avoiding the dust from drifting randomly in the dust suppression space and further reducing the possibility of dust polluting the environment.

[0019] Meanwhile, the detachable connection of the dust collection screen makes it easy for operators to clean the screen and also facilitates its reuse.

[0020] Optionally, the collection assembly also includes a dust collection box located directly below the dust collection net, with an open top and the dust collection box being detachably and fixedly connected to the fixed end of the side plate.

[0021] By adopting the above technical solution, during the operation of the tamping machine, the top plate will vibrate vertically, which will cause the dust collection screen to vibrate vertically. During the vertical vibration of the dust collection screen, the dust on the dust collection screen will fall off more easily, which is conducive to the dust falling into the dust collection box below the dust collection screen.

[0022] After the dust falls off the dust collection screen, it is easier for dust carried in the flowing air to adhere to the dust collection screen, so that the dust collection screen can be used for a long time, thereby further improving the practicality of the compactor.

[0023] Optionally, the collection assembly further includes an anti-reverse tube that snaps into the top opening of the dust collection box. The anti-reverse tube is S-shaped in the vertical direction, and the top opening of the anti-reverse tube is located directly below the dust collection screen.

[0024] By adopting the above technical solution, the anti-backflow pipe can prevent dust from entering the dust suppression space from the dust collection box, thus preventing secondary pollution from the dust; the snap-fit ​​design between the dust collection box and the anti-backflow pipe makes it easy for the operator to clean the dust in the dust collection box.

[0025] Optionally, a flexible pad is fixedly provided on the bottom end face of the fixed end of the side plate.

[0026] By adopting the above technical solution, the flexible mat layer can fully contact the ground, improving the airtightness of the dust suppression space, so that dust can be fully confined within the dust suppression space, avoiding dust pollution to the working environment.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By setting up dust suppression components, the dust generated during the compaction process is confined within the dust suppression space, preventing dust from polluting the working environment and thus improving the practicality of the compactor;

[0029] 2. By setting up blowing and collecting components, the airflow guides the dust in the dust suppression space, causing the dust to adhere to the dust collection net. The vertical vibration of the compactor itself causes the dust collection net to vibrate vertically, allowing the dust on the net to enter the dust collection box. This also facilitates the subsequent adhesion of dust to the dust collection net, enabling the dust suppression work to be carried out for a long time, thereby further improving the practicality of the compactor.

[0040] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0041] This application discloses a compaction device for foundation earthwork backfilling. (Refer to...) Figure 1 and Figure 4 A compaction device for basic earthwork backfilling includes a compactor body 11, a dust suppression component 2, a collection component 5, a blowing component 3, and an air supply component 4. The dust suppression component 2 is adapted to the ground to form a dust suppression space, so that the dust generated by the compactor body 1 during operation is confined within the dust suppression space. The collection component 5 and the blowing component 3 are both located within the dust suppression space and are arranged opposite to each other. The collection component 5 is used to collect dust near itself, and the blowing component 3 is used to spray gas, and the sprayed gas is used to blow the dust in the side plate 22 onto the collection component 5. The air supply component 4 is used to supply gas to the blowing component 3.

[0042] The dust suppression component 2 includes a top plate 21, a side plate 22, a spring 23, and a flexible pad 24. The top plate 21 is horizontally arranged, and the compactor body 1 passes through the top plate 21 and is fixedly connected to the top plate 21. The side plate 22 is located below the top plate 21 and is sleeved on the compactor body 1. There is a distance between the side plate 22 and the compactor body 1. The side plate 22 is a telescopic plate structure and extends and retracts in the vertical direction. The movable end of the side plate 22 is fixedly connected to the top plate 21. The flexible pad 24 is fixedly arranged on the bottom end face of the fixed end of the side plate 22. The flexible pad 24 is used to tightly abut against the ground. The spring 23 is vertically arranged in the rodless cavity at the fixed top end of the side plate 22.

[0043] It should be noted that the side panel 22, the top panel 21, and the ground form a relatively independent dust suppression space; the flexible pad 24 can be tightly pressed against the ground by the weight of the side panel 22; the spring 23 serves as a further support, thus providing double protection for the tight contact between the flexible pad 24 and the ground.

[0044] The collection component 5 includes a dust collection net 51, a dust collection box 52, and an anti-backflow pipe 53. The dust collection net 51 is vertically installed in the dust suppression space and located on one side of the compactor body 1. The dust collection net 51 is bolted to the top plate 21. The dust collection box 52 is located directly below the dust collection net 51 and is bolted to the fixed end of the side plate 22. The top of the dust collection box 52 is an open structure. The anti-backflow pipe 53 is S-shaped in the vertical direction and is located between the dust collection box 52 and the dust collection net 51. The top opening of the anti-backflow pipe 53 is located directly below the dust collection net 51, and the bottom opening of the anti-backflow pipe 53 is engaged with the top opening of the dust collection box 52.

[0045] The purging assembly 3 includes a nozzle 31 and a connecting pipe 32. The nozzle 31 is fixedly connected to the side plate 22 and several are arranged in the vertical direction. Several connecting pipes 32 are arranged, and adjacent nozzles 31 are interconnected through the connecting pipes 32.

[0046] The air supply assembly 4 includes an air pump 41 and an air supply pipe 42. One end of the air supply pipe 42 is connected to one of the nozzles 31, and the other end is connected to the outside. The air supply pipe 42 is fixedly connected to the compactor body 1 and is a flexible hose. The air pump 41 is installed on the air supply pipe 42 and is fixedly installed on the compactor body 1.

[0047] The implementation principle of a compaction device for backfilling foundation soil in this application embodiment is as follows: when the operator performs compaction work, the flexible cushion layer 24 is in close contact with the ground, so that the ground, side plate 22 and top plate 21 form a dust suppression space, and the dust generated during the compaction work is constrained in the dust suppression space.

[0048] When dust needs to be collected in the dust suppression space, the operator starts the air pump 41. The air pump 41 fills the nozzle 31 with air through the air supply pipe 42, so that the gas can be sprayed out through the nozzle 31 and flow towards the dust collection net 51. During the flow, the gas carries the dust in the air, so that the dust adheres to the dust collection net 51.

[0049] During the compaction process, the top plate 21 vibrates vertically along with the compactor body 1, causing the dust collection net 51 to vibrate vertically as well. As the dust collection net 51 vibrates vertically, the dust on the dust collection net 51 falls into the anti-reverse pipe 53 below the dust collection net 51 and enters the dust collection box 52 through the anti-reverse pipe 53, thus achieving dust collection and effectively improving dust pollution during the compaction process, thereby further improving the practicality of the compactor.

[0050] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
