Technical Field

The invention relates to a road sweeper, in particular to a road sweeper adopting a high-pressure jet water column as a tool for sweeping an auxiliary road.

Background

The prior known auxiliary road sweeper comprises two types, one type is a full-brush type sweeper with two disk brushes on the left side and the right side respectively and a rolling brush in the middle, the other type is a sweeping and sucking type sweeper with two disk brushes on the left side and the right side respectively and a vacuum sucker in the middle, because the auxiliary road is generally 3-4 m wide, the two sides are required to be swept respectively during operation, the operation speed is 5km/h, the sweeping quality macroscopically reaches more than 95%, the defects are that the efficiency is low, and the sweeping and brushing sweeping are easy to generate ash. When the vacuum garbage suction device is used for sucking garbage, strong airflow is not easy to control after encountering ash, secondary pollution can be caused because the whole road cannot be specially sprayed with moisture, and an operator can wear the mask sometimes.

Disclosure of Invention

In order to overcome the defects and develop a novel road sweeper, the water jet type auxiliary road sweeper (hereinafter referred to as the road sweeper) of the invention uses a high-pressure jet water column generated by a high-pressure water pump as a tool to sweep the road surface, and the pressure of the water column is 100kg/cm²The flow is 10L/min, and the garbage can be completely washed to the right tooth side from the left side by strong momentum, so that the whole road surface cleaning is completed.

The technical scheme adopted by the invention for solving the technical problem is as follows: after the water tank is arranged on the machine, the high-pressure water pump is arranged below the left girder, and the nozzle is arranged on the left side of the machine head. A disk brush is arranged in front of the nozzle, a disk brush is also arranged on the right side of the machine head, and a vacuum chuck is arranged below the machine head. A garbage can is arranged on the right side of the cab, a suction tube is used for communicating the suction cup with the garbage can, a hole is formed in the left wall of the garbage can, an air pipe is connected with an air suction port of a high-pressure fan arranged below a seat cushion of the cab, the fan is started, and the suction cup obtains vacuum.

The nozzle is inclined forwards by 25 degrees so as to be shot to the right tooth side to form a reflected water flow with a forward component force, which is favorable for pushing the garbage to move forwards.

During operation, the road sweeper runs to the left, the high-pressure water pump and the left disc brush are started, the left disc brush sweeps garbage at dead angles between the nozzle and the left tooth edge clockwise to the front of a water column, the water column sweeps the garbage to the right tooth edge, the garbage on the right side is pushed together to move forwards, when more garbage exists, the water pump and the left disc brush are closed, the road sweeper runs to the right, the right brush disc and the high-pressure fan are started, the right disc brush sweeps the garbage on the right tooth edge anticlockwise to the front of the vacuum chuck, the road sweeper only needs to move forwards for about one meter, the garbage can be fully absorbed, after dust collection is completed, the fan and the right disc brush are closed, the road sweeper runs to the left again, and all operation can be completed repeatedly.

When the dustbin is full, the side door can be opened to hook out the garbage or hang the bag for bagging.

The brush disc should be close to the nozzle installation, and the brush limit should be tangent with the water column, does benefit to and obtains the water foam, makes the brush disc moist.

The garbage can sucks garbage during dust collection, and simultaneously can suck water, two small holes are formed in the bottom surface of the garbage can for water drainage, a valve block is arranged below each small hole, the valve block is in an inverted U shape and is supported by a supporting frame, the maximum distance between the upper part and the lower part is 5mm, when the garbage can is under vacuum, the valve block is attached to the valve block and is sealed, and when the garbage can is under normal pressure, the valve block falls under the dead weight, and water drainage can be achieved.

In the dustbin, the vent department has a filter mantle, when the evacuation, blocks rubbish and gets into the fan.

The invention has the beneficial effects that: 1. the cleaning surface has wide view and the auxiliary road can be finished at one time. 2. The sweeping quality is high, the water column does not sweep the garbage, and the road surface is also flushed. 3. No dust emission and complete environmental protection. 4. The efficiency is high, and is more than twice of that of the existing road sweeper. 5, the adaptability is good, and even if the vehicle is parked on the right of the road, the water spraying can be carried out under the vehicle. In contrast, it is a scratch product.

The invention is further described below with reference to the accompanying drawings and examples.

FIG. 1 is a schematic plane structure of the present invention.

Fig. 2 is a view of the drain valve in fig. 1 in the direction of a.

In the attached figure 1, a water tank 1, a high-pressure water pump 2, a nozzle 3, a left disc brush 4, a water column 5, a left tooth edge 6, a right tooth edge 7, a right disc brush 8, a vacuum sucker 9, a suction tube 10, a dustbin 11, a water discharge hole 12, a filter screen 13, an air pipe 14, a high-pressure fan 15, a side door 16 and a crossbeam 17 are arranged.

In FIG. 2, 18 is a valve plate, 19 is a support frame.

Detailed Description

In the attached figure 1, a water tank 1 is placed behind a road sweeper, a high-pressure water pump 2 is placed on a crossbeam 17, a nozzle 3 is placed at the front left side of the road sweeper under the left side, the water tank 1, the high-pressure water pump 2 and the nozzle 3 are communicated by a low-pressure pipe and a high-pressure pipe respectively, the nozzle 3 is tilted forward by 25 degrees, the water pump is started to wipe the ground, the water column is tilted forward by 25 degrees and is irradiated to a right tooth edge 7, a left disc brush 4 is installed close to the nozzle and is tangent to the water column 5, the road sweeper moves to the left during operation, the left disc brush 4 rotates garbage on the left tooth edge 6 clockwise to sweep the front of the water column 5, the water column sweeps the right tooth edge, when more and more garbage is accumulated on the right tooth edge 7, the water pump 2 and the left disc brush 4 are closed, the road sweeper moves to the right, the right disc brush 8 is close to the right tooth edge 7, the right disc brush and the high-pressure fan 15 are started, the right disc brush 8 rotates anticlockwise to sweep the garbage on the right tooth edge 7 to sweep the front of a vacuum chuck 9, and only one meter is needed, the light of the piled garbage is absorbed, and the dust collection is completed.

The vacuum sucker 9 is communicated with the suction drum 10, the dustbin 11, the air pipe 14 and the suction inlet of the high-pressure fan 15 in sequence, and the vacuum can be obtained by starting the fan.

After dust collection is completed, the fan 2 and the right disc brush 8 are closed, the road sweeper operates in a left-hand mode, the above procedures are repeated, when the dustbin 11 is full, the machine is stopped, the side door 16 is opened, and garbage is hooked or bagged.

A filter screen 13 is arranged at the air exhaust opening of the garbage can 11 to prevent garbage from entering the fan 15 from the air exhaust opening, so that the fan is protected.

In the attached figure 2, 18 is a valve plate which is in an inverted U shape and is supported by a supporting frame 19, the maximum distance between the upper part and the lower part is 5mm, when the vacuum is pumped, the valve plate is attached to the bottom surface of the garbage can to seal a small hole, and when the pressure is normal, the valve plate falls down by the dead weight and can discharge water.
