Description
Technical Field
[0001] The utility model relates to the field of road garbage treatment and comprehensive utilization, in particular to a garbage sweeper, and more particularly to a ground dust collecting device in the garbage sweeper. Background Art
[0002] Garbage sweepers are used to sweep garbage on the ground. Some garbage sweepers can also transport domestic garbage and road garbage through the car body. Garbage sweepers are one of the conventional equipment in the sanitation system. Compared with manual sweeping, garbage sweepers can greatly save manpower and clean up garbage on the road quickly and well. The garbage sweeper includes a ground dust collection device located at the rear of the frame, and the ground dust collection device includes a mounting frame, and a chassis buckled to the ground is provided on the mounting frame. A sweeping piece for sweeping the ground is provided in the chassis, and the sweeping piece can be a sweeping roller with a brush, or any technology in the prior art such as a rotary water spraying device. A dust suction port is connected to the front of the sweeping piece, and the dust suction port absorbs ground dust during the operation of the garbage sweeper, and at the same time sweeps the brush to collect debris at the front.
[0003] During use, the front of the cavity formed by the chassis is sucked through the dust suction port, and a gap is left between the rear of the chassis and the ground. The outside air enters the cavity from the gap at the rear of the chassis, flows forward to the dust suction port, and then flows out from the dust suction pipe. The air flow drives water, dust, leaves and other debris into the dust suction pipe, thereby realizing the cleaning and collection of ground garbage.
[0004] In the prior art, in order to regulate the flow speed of air, that is, the wind speed in the cavity, the height of the roller on the chassis can be adjusted, and then the distance between the lower end of the chassis and the ground can be adjusted, and the height value of the gap can be adjusted. When the gap height value is larger, the gap for air to enter is larger, the air circulation channel is wider, and the wind speed is slower; when the gap height value is smaller, the gap for air to enter is smaller, the air circulation channel is narrower, and the wind speed is faster.
[0005] During normal use, the gap is generally made smaller, the wind speed is increased, and debris such as water, leaves, and gravel are blown toward the vacuum tube.
[0006] However, the prior art has always sought to reduce the gap between the lower rear end of the chassis and the ground, but when the cleaned ground contains a large amount of floating dust, sand and other materials, it is still easy to have a poor cleaning effect. When the cleaning effect is poor, it is necessary to further reduce the vehicle speed or clean the ground a second time. Utility Model Content
[0007] The main purpose of the utility model is to provide a ground dust collecting device to solve the problem in the prior art that when the ground to be cleaned contains a large amount of floating dust, sand and other substances, the cleaning effect is poor.
[0008] The utility model provides a floor dust collection device, which includes a mounting frame, a chassis buckled to the ground is arranged on the mounting frame, a sweeping piece is arranged in the middle of the chassis, a dust suction port is arranged in the front of the sweeping piece, and a dust suction pipe is connected to the dust suction port. An opening is left at the rear of the chassis, an opening and closing door is arranged at the opening, the opening is blocked when the opening and closing door is buckled, and the opening is opened when the opening and closing door is closed.
[0009] Preferably, the cross-section of the opening and closing door is L-shaped, and the opening and closing door comprises a transverse plate and a vertical plate, the front of the transverse plate is hingedly connected to the rear of the chassis, and the vertical plate is connected to the rear of the transverse plate and extends downward.
[0010] Preferably, telescopic rods are respectively arranged on both sides of the rear portion of the chassis, and rear rollers are arranged on the rear portion of the chassis, and the rear rollers are arranged on the telescopic rods.
[0011] More preferably, the opening and closing door is arranged between the two rear rollers.
[0012] Preferably, the sweeping member comprises a sweeping roller arranged transversely, a brush is arranged on the sweeping roller, and the sweeping roller is connected to a driving device for driving the sweeping roller to rotate.
[0013] Preferably, the sweeping member comprises a rotating frame, on which a plurality of water spray pipes are arranged, and the water spray pipes spray clean water onto the ground.
[0014] Preferably, a sealing strip is provided at the connection between the opening and closing door and the chassis.
[0015] Preferably, a handle is also provided on the opening and closing door.
[0016] Preferably, when the opening and closing door blocks the opening, the upper portion of the opening and closing door is a cardboard, and the lower portion of the opening and closing door is a rubber plate.
[0017] Compared with the prior art, the ground dust collecting device provided by the utility model has the following beneficial effects:
[0018] The above-mentioned ground dust collection device is provided with an opening at the rear of the chassis, and an opening and closing door is provided at the opening. The provision of the above-mentioned opening and closing door makes it convenient for the staff to open the opening and closing door at the rear of the chassis, and to check or repair and maintain the various components under the chassis. Most importantly, when the opening and closing door is closed, the gap between the rear of the chassis and the ground can be reduced, thereby increasing the wind speed; when the opening and closing door is opened, a larger air inlet channel, i.e., the above-mentioned opening, can be formed at the rear of the chassis, so that the air at the rear enters the lower part of the chassis from the opening with a larger cross-section, thereby increasing the airflow surface. When cleaning the ground containing a large amount of floating dust and sand, although the wind speed is lower when cleaning in this way, the cleaning effect is better, and lighter garbage such as floating dust and sand from various places can be blown to the suction pipe, thereby realizing the collection and cleaning of garbage.
