Description

Technical Field

[0001] The utility model belongs to the technical field of artificial backfilling, and in particular relates to a backfilling device for civil air defense engineering buildings. Background Art

[0002] The existing backfill equipment tends to pile up the soil at different positions when filling the pit, resulting in uneven soil volume at different positions, which affects the filling effect in the later stage. Among them, the "A Backfill Device for Civil Air Defense Engineering Buildings" disclosed in the application number "CN202322764718.5" is also an increasingly mature technology. The device is moved to the top of the position to be backfilled by the crawler wheels, and the height of the discharge end of the discharge barrel and the backfill position is adjusted by the extension and shortening of the telescopic end of the hydraulic telescopic rod, which facilitates filling while avoiding a large amount of dust generated by the raw materials due to the height being too high. When backfilling, the raw materials are poured into the inlet by the material transport vehicle. The inside of the hopper is then driven by a driving motor to rotate the reciprocating screw, which drives the slide plate to move back and forth along the slide, and the discharge barrel is driven to move back and forth by the slide plate, so that the discharge barrel spreads the raw materials inside the pit to fill the pit. The backfill efficiency is improved by this device, but the device also has the following defects: in actual use, it is not convenient to transport the ground soil to the backfill pit. During use, soil blocks leak into the funnel. Due to the high moisture content in the soil, multiple large lumps of soil can easily block the discharge point. After filling the pit, the soil surface needs to be filled and leveled, which requires secondary rework and backfilling, reducing the backfill efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a backfill device for civil air defense engineering buildings, aiming to solve the problem in the prior art that it is inconvenient to transport ground soil to the backfill pit, and during use, soil blocks leak into the funnel. Due to the high moisture content in the soil, multiple large blocks of soil clump together and easily block the material discharge point. After filling the pit, the soil surface needs to be leveled, which requires secondary rework and backfilling, reducing the backfill efficiency.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: it includes a track seat, a support frame is provided on the top of the track seat, a diversion funnel is embedded in the top of the support frame, a feeding funnel is provided on the top, a servo motor is provided on one side of the support frame, the output end of the servo motor passes through one side of the support frame and is fixedly connected to an adjusting rod, the adjusting rod is rotatably connected to the top of the inner wall of the diversion funnel, a number of eccentric stirring blocks are distributed on the surface of the adjusting rod, a stabilizing frame is provided on the other side of the support frame, a feeding auger pipe is provided on one side of the stabilizing frame, a feeding motor is provided at one end of the feeding auger pipe, a connecting pipe is provided on one side of the top of the feeding auger pipe, a shoveling funnel is provided at the other end of the feeding auger pipe, and one end of the connecting pipe is sealed and connected to one side of the top of the feed funnel.

[0005] In an implementation scheme of a backfill device for civil air defense engineering buildings of the present utility model, an auxiliary frame is provided on one side of the support frame, and a filling roller is rotatably connected to one side of the bottom of the auxiliary frame.

[0006] In this solution, after the filling is completed, when the crawler seat moves forward, the leveled soil pile in the pit is compacted by the filling roller, avoiding uneven distribution of the soil pile in the backfill pit and causing workers to rework again.

[0007] In an implementation scheme of a backfill device for civil air defense engineering buildings of the present utility model, an auxiliary shovel is provided on one side of the track seat.

[0008] In this solution, when the filling is completed, the crawler seat moves forward, the auxiliary shovel flattens the soil pile in the backfill pit, and pushes the excess soil pile into the pit in front to flatten the uneven soil pile in the backfill pit.

[0009] In an implementation scheme of a backfill device for civil air defense engineering buildings of the present utility model, an auxiliary motor is provided on one side of the shoveling funnel, and an output end of the auxiliary motor passes through one side of the shoveling funnel and is fixedly provided with a transport wheel.

[0010] In this solution, the crawler seat moves forward, and the shoveling funnel moves forward to shovel the soil pushed on the ground into the shoveling funnel. At this time, the auxiliary motor rotates the transport wheel to push the shoveled soil to the feed port at the bottom of the feeding auger pipe. The feeding motor rotates the auger rod in the feeding auger pipe to transport the soil. The transported soil enters the feed funnel through the connecting pipe and leaks into the eccentric stirring block. At this time, the servo motor rotates the eccentric stirring block on the adjusting rod to break up the falling soil blocks to prevent the soil blocks from blocking the channel.

[0011] In an implementation scheme of a backfill device for civil air defense engineering buildings of the present utility model, an auxiliary conveying pipe is provided at the bottom discharge port of the diversion funnel.

[0012] In this solution, the transported soil leaks out of the auxiliary conveying pipe and evenly leaks into the backfill pit.

[0013] In an implementation scheme of a backfill device for civil air defense engineering buildings of the present utility model, auxiliary buffer wheels are provided on both sides of the bottom of the shoveling funnel.

[0014] In this solution, during the forward movement of the shoveling funnel, the shoveling funnel is assisted in its movement by the auxiliary buffer wheel, thereby improving the stability of the shoveling funnel in moving the soil.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1) The crawler seat moves forward, and the shoveling funnel moves forward to shovel the soil pushed on the ground into the shoveling funnel. At this time, the auxiliary motor rotates the transport wheel to push the shoveled soil to the feeding port at the bottom of the feeding auger pipe. The feeding motor rotates the auger rod in the feeding auger pipe to transport the soil, reducing the labor intensity. The transported soil enters the feeding funnel through the connecting pipe and leaks into the eccentric stirring block. At this time, the servo motor rotates the eccentric stirring block on the adjusting rod to break up the falling soil blocks to prevent the soil blocks from blocking the channel.

[0017] 2) The crawler seat moves forward, and the auxiliary shovel flattens the soil pile in the backfill pit, and pushes the excess soil pile into the pit in front to flatten the uneven soil pile in the backfill pit. When the filling is completed, when the crawler seat moves forward, the filling roller compacts the flattened soil pile in the pit to avoid uneven distribution of soil piles in the backfill pit, which causes workers to rework twice.
