Description

Technical Field

[0001] The utility model relates to the field of earthwork backfilling, in particular to an earthwork backfilling device capable of reducing dust. Background Art

[0002] Earthwork backfilling refers to the work of filling and ramming the excavated space in construction projects. It is an important link in earthwork projects, aiming to provide the bearing capacity of buildings through filling and ramming, and ensure the stability and safety of the project.

[0003] During earthwork backfilling, dust may be generated due to the relatively dry raw materials. These dusts will not only cause dust to fly in the construction site, seriously affecting the sight and operation safety of construction workers, but also may cause safety accidents such as slipping and blocked sight. At the same time, the diffusion of dust will also pollute the surrounding environment, affect air quality, and have an adverse impact on the lives and health of surrounding residents.

[0004] Therefore, in view of the problem that dust may be generated due to relatively dry raw materials during earthwork backfilling, an earthwork backfilling device capable of reducing dust can be designed to settle the dust that may be stirred up during earthwork backfilling, protecting the construction site environment and the surrounding environment. Content of the Utility Model

[0005] In order to overcome the problem that dust may be generated due to relatively dry raw materials during earthwork backfilling.

[0006] The technical solution of the utility model is: an earthwork backfilling device capable of reducing dust, which includes a frame, wheels, a placement plate, a water mist spraying structure, a water storage tank, a waterproof plate and a ramming machine structure. Four wheels are arranged at the four corners of the bottom of the frame. Reinforcing ribs are fixedly connected between the horizontal bars and vertical bars inside the frame. The placement plate is fixedly connected to the rear side inside the frame. Reinforcing ribs are also arranged between the placement plate and the rear vertical bars. The water mist spraying structure is provided with a water delivery pipe, a water pump and water mist nozzles. The water delivery pipe is fixedly connected to the upper end of the frame. The water pump is fixedly connected to the inner side of the water pipe. The water mist nozzles are arranged at the front side inside the frame. The water storage tank is fixedly connected to the rear side of the top of the frame. The ramming machine structure is provided with a motor and a rammer. The waterproof plate is arranged between the motor and the water mist nozzles. The rammer is arranged at the bottom inside the frame.

[0007] Preferably, since the water content inside the backfilled earthwork cannot be predicted, the water mist spraying structure can spray water on the backfilled earthwork while the construction machinery is backfilling the earthwork, settling the dust that may be stirred up to the ground, reducing the dust on the construction site, facilitating the movement of the wheels when the device moves, and there are two rammers arranged at the rear side of the device to continuously ram the backfilled earthwork to compact the backfilled earthwork to the standard. The waterproof board between the rammer structure and the water mist spraying structure separates the two structures to protect the motor inside the rammer structure from being sprayed by the water mist.

[0008] Preferably, reinforcing ribs are arranged between the vertical rods and the horizontal rods of the frame. The reinforcing ribs are placed obliquely to form a triangular stable structure with the vertical rods and the horizontal rods. There are also obliquely placed reinforcing ribs between the bottom of the placing plate and the vertical rods of the rear frame, so that the frame can bear the weight of the water storage tank and the vibration brought by the rammer.

[0009] Preferably, a water filling hole is arranged at the top of the water storage tank. The water storage tank is arranged at the rear side of the top of the frame. Water is conveyed to the water mist nozzles through the water delivery pipe, water pump and pressurizing pipe inside the water mist spraying structure. The water delivery pipe is fixedly connected to the upper part of the horizontal rod, and the pressurizing pipe is fixed inside the inner horizontal rod. Water can be stored in the water storage tank to settle the dust, or a water supply pipe can be directly connected to the water delivery pipe to obtain the water source for settling the dust.

[0010] Preferably, the water mist spraying structure includes a water delivery pipe, a water pump, a pressurizing pipe and water mist nozzles. The water delivery pipe is fixedly connected to the upper part of the horizontal rod. Two water pumps are arranged inside the water delivery pipes on both sides. The pressurizing pipe is fixedly connected to the bottom of the front side of the water delivery pipe. Four water mist nozzles are fixedly connected to the bottom of the pressurizing pipe. Water pumps are arranged on both sides to simultaneously pump and convey water to the water mist nozzles, so that the sprayed water mist has a wide coverage area and a good settling effect.

[0011] Preferably, the rammer structure includes a machine box, a motor, a transmission shaft and a rammer. Two machine boxes are fixedly connected to the placing plate. The motor is arranged at the rear side of the machine box. The transmission shaft is arranged at the bottom of the machine box. The rammer is fixedly connected to the bottom of the transmission shaft. Two rammers are used to alternately ram the backfilled earthwork back and forth, with higher efficiency and better effect.

[0012] Preferably, two connecting rods are arranged on both sides of the waterproof board. The combined width of the waterproof board and the connecting rods is the same as that of the horizontal rod in the left-right direction inside the frame. An opening with the same thickness as the transmission shaft is opened in the placing plate. The waterproof board and the placing plate form a placing area to protect the important machine box and motor inside the rammer structure.

[0013] Preferably, the wheels are arranged at the four corners of the bottom of the vertical rods inside the frame. Right-angle chamfers are provided on the inner sides of the vertical rods inside the frame, and right-angle chamfers are also provided at the four corners of the rammer at the rear bottom, creating a certain distance between the vertical rods and the rammer. At the same time, compared with the traditional square rammer, it can generate greater pressure on the ground to be rammed, with better effects.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. Since the water content inside the backfilled earth and stone cannot be predicted, the water mist spraying structure can spray water on the backfilled earth and stone while the construction machinery is backfilling the earth and stone, settling the dust that may be stirred up to the ground, reducing the dust on the construction site. Two ways of water supply can be adopted, namely, water supply from the water storage tank and direct water supply through pipes.

[0016] 2. The wheels facilitate the movement of the device. Two sets of rammers are provided at the rear of the device to continuously ram the backfilled earth and stone, compacting the backfilled earth and stone to meet the standards.

[0017] 3. The waterproof board between the rammer structure and the water mist spraying structure separates the two structures, protecting the motor inside the rammer structure from being sprayed by the water mist. Description of the Drawings
