Description

Technical Field

[0001] The utility model relates to the technical field of trench backfilling, in particular to a quick trench backfilling feeding device. Background Art

[0002] Municipal pipeline construction refers to various pipeline construction projects under urban roads, mainly including water supply pipelines, drainage pipelines, gas pipelines, heat pipelines, power pipelines, etc. These pipelines are important components of urban infrastructure and are of great significance to the normal operation of the city and the lives of residents.

[0003] The basic process of municipal pipeline construction includes pipe pit excavation, pipeline installation, construction of ancillary facilities, functional testing, maintenance and repair, etc. During the excavation project, attention should be paid to the stability of the slope to prevent earth collapse. During the pipeline installation process, socket or flange connections should be used to ensure that the joints are firm and reliable. The construction of ancillary facilities includes ditches, pipes, process wells, gate wells, inspection wells, etc., and attention should be paid to the construction requirements of masonry projects. Functional experiments include pressure pipe water pressure tests, non-pressure pipe tightness tests, etc. to ensure the quality and safety of the pipeline.

[0004] After the pipeline construction is basically completed, the excavated trench needs to be backfilled. However, the roads in rural areas are narrow and transportation is inconvenient. Before backfilling, the backfill material needs to be transported to the vicinity of the construction site by a smaller transfer vehicle, and then the backfill material in the transfer vehicle is poured into the trench on the ground.

[0005] However, after the common transfer vehicle transfers the backfill material to the vicinity of the trench, construction workers are still required to fill the backfill material evenly into the trench, which consumes a lot of manpower and prolongs the construction period. In view of this, the present application proposes a quick trench backfilling feeding device. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a quick trench backfilling feeding device, which has the advantages of directly and evenly filling the backfill material from the transfer vehicle into the trench quickly and evenly, and solves the problem that after the transfer vehicle transfers the backfill material to the vicinity of the trench, the construction workers are still required to fill the backfill material evenly into the trench, which consumes a lot of manpower and prolongs the construction period.

[0007] In order to achieve the above-mentioned purpose of directly and evenly and quickly filling the backfill material from the transfer vehicle into the trench, the utility model provides the following technical solutions: a quick trench backfilling material discharging device, comprising a transfer vehicle, a bucket is rotatably mounted on the top of the transfer vehicle, two mounting ear plates are fixedly mounted on the bottom of the bucket near the tail, a mounting shaft is fixedly mounted between the two mounting ear plates, and a material bucket is rotatably mounted on the surface of the mounting shaft;

[0008] Two connecting circular plates are fixedly mounted on the top of the hopper, and one side of the connecting circular plate is provided with a mounting through hole matched with the mounting shaft.

[0009] Furthermore, a flow guide liner is fixedly mounted on the inner bottom wall of the hopper, and a round bottom groove is provided at the bottom of the flow guide liner.

[0010] Furthermore, a spiral propulsion rod is rotatably mounted on the inner side wall of the hopper, and the spiral propulsion rod contacts the surface of the round bottom groove.

[0011] Furthermore, a propulsion motor is fixedly installed on one side of the hopper, and the output shaft of the propulsion motor rotates through one side of the hopper and is fixedly connected to one end of the spiral propulsion rod.

[0012] Furthermore, an output pipe is fixedly installed on a side of the hopper away from the propulsion motor, and one end of the spiral propulsion rod extends to the inside of the output pipe.

[0013] Furthermore, a control pipe is bolted to one side of the output pipe via a connecting flange, a control valve is fixedly installed on the surface of the control pipe, and a flexible pipe is fixedly installed at one end of the control pipe away from the connecting flange.

[0014] Furthermore, a mounting rod is fixedly installed at the rear end of the truck bucket, a tailgate is rotatably installed on the surface of the mounting rod, a flipping hydraulic cylinder is rotatably installed on the top of the transfer vehicle, and the movable end of the flipping hydraulic cylinder is rotatably connected to the bottom of the truck bucket.

[0015] Compared with the prior art, the utility model provides a quick trench backfilling device, which has the following beneficial effects:

[0016] 1. The quick trench backfilling feeding device can rotate the hopper between the mounting ear plates through the mounting shaft, so that the hopper can rotate at the bottom of the open end of the bucket. Under the action of gravity, the opening direction of the hopper is always upward. When the hopper is raised to pour out the backfill material, the backfill material enters the hopper and is then output through the flexible pipe. The staff only needs to control the direction of the flexible pipe to evenly fill the backfill material into the trench, which solves the problem that after the transfer vehicle transfers the backfill material to the vicinity of the trench, the construction personnel still need to evenly fill the backfill material into the trench, which consumes a lot of manpower and prolongs the construction period.

[0017] 2. The quick trench backfilling and discharging device arranges a spiral propulsion rod inside the hopper, and drives the spiral propulsion rod to rotate through a propulsion motor to transfer the backfill material to the inside of the output pipe, thereby preventing the backfill material from accumulating inside the hopper and being unable to be discharged. This solves the problem that part of the backfill material accumulates inside the hopper and is inconvenient to be discharged, resulting in material waste. BRIEF DESCRIPTION OF THE DRAWINGS
