Description

Technical Field

[0001] The utility model relates to a sweeper, in particular to a road sweeper, and belongs to the technical field of sanitation equipment. Background Art

[0002] In the cleaning and maintenance of urban roads and public places, how to clean up garbage and dust efficiently has always been a key challenge.

[0003] Traditional cleaning equipment usually relies on mechanical sweeping brushes or simple vacuum devices. Although they can remove garbage and dust to a certain extent, they are often accompanied by serious dust problems during subsequent garbage disposal, which not only threatens the health of workers, but also pollutes the environment. Utility Model Content

[0004] Based on the above background, the purpose of the utility model is to provide a road sweeper with a simple structure that reduces dust during subsequent garbage processing, thereby solving the problems described in the background technology.

[0005] In order to achieve the above-mentioned utility model purpose, the utility model provides the following technical solutions:

[0006] A road sweeper, comprising a vehicle body, the vehicle body being provided with a sweeping unit, a collecting box and a dust collecting device, the vehicle body being divided into a vehicle head and a vehicle body, the sweeping unit being located at the vehicle head and being connected to the vehicle head, the collecting box being located at the vehicle body and being connected to the vehicle body, a dust collecting device being arranged between the sweeping unit and the collecting box, the sweeping unit being connected to the collecting box via the dust collecting device, and the dust collecting devices being connected to the vehicle head and the vehicle body;

[0007] A filter is arranged in the collection box, and fixed plates are arranged at both ends of the bottom of the filter, the fixed plate and the filter are an integral structure, a plurality of vibration dampers are arranged between the fixed plate and the collection box, the vibration dampers are connected to the fixed plate and the collection box, an oscillator is arranged on the side of the fixed plate away from the vibration damper, the oscillator is connected to the filter plate, a baffle is arranged on the side of the oscillator away from the fixed plate, the baffle is an integral structure with the filter, a sprinkler pipe is arranged on the side of the baffle away from the oscillator, the sprinkler pipe is connected to the baffle, a plurality of water spray outlets are arranged on the surface of the sprinkler pipe, and the water spray outlets are connected to the sprinkler pipe.

[0008] The cleaning unit is located at the front of the vehicle and is responsible for cleaning the road surface and collecting the garbage and dust in one place. This is the first step in the entire cleaning process to ensure that the garbage and dust are effectively gathered. Then, the dust suction device uses the principle of negative pressure to suck the garbage and dust collected by the cleaning unit into the collection box for collection. The efficient operation of the dust suction device ensures that the garbage and dust can be sucked away quickly and thoroughly, thereby improving the cleaning efficiency.

[0009] The garbage and dust entering the collection box will first fall on the filter, and the vibrator is installed at the bottom of the filter, so that the filter vibrates through the vibration generated by the vibrator. During the vibration process, larger garbage will be left on the upper part of the filter, while finer dust will fall to the lower part of the filter through the vibration. This process not only improves the separation effect of garbage and dust, but also prevents the filter from being blocked, ensuring the smooth progress of the filtering process.

[0010] To further suppress dust, the sprinkler pipe sprays water mist through the nozzles installed on its surface. The water mist evenly sprayed by the sprinkler pipe effectively suppresses the dust under the filter, thus preventing dust from flying during the subsequent treatment of garbage and dust. This not only helps to keep the air fresh and reduce dust pollution, but also greatly reduces the health risks of workers when handling garbage.

[0011] Preferably, the cleaning unit includes two extension arms, two cleaning discs and a cleaning roller. Two extension arms are arranged at the front of the vehicle head. One end of the extension arm is connected to the vehicle head. The other end of the extension arm is arranged with a cleaning disc, and the cleaning disc is connected to the extension arm. A cleaning roller is arranged at the bottom of the vehicle head, and the cleaning roller is connected to the vehicle head.

[0012] The sweeping disc sweeps the garbage and dust on the ground to the center area of ​​the sweeping unit through rotational motion, which is convenient for subsequent dust suction and collection. The extension arm can extend the sweeping disc to the cleaning area, allowing the sweeper to cover a wider range. This helps the sweeper to flexibly adjust the cleaning range during operation to adapt to different road widths and shapes. The sweeping roller is located at the bottom of the vehicle head. Through rotational motion, it can further collect the garbage and dust swept to the center area by the sweeping disc and move it backwards to make it close to the entrance of the dust suction device.

[0013] Preferably, the output end of the dust suction device is located above the filter net.

[0014] Since the output end of the dust collection device is located above the filter, garbage and dust can be quickly intercepted and separated by the filter, reducing the retention time of impurities in the collection box.

[0015] Preferably, the vehicle body is provided with a water tank, the water tank is connected to the vehicle body, and the water tank is communicated with a sprinkler pipe.

[0016] The water tank provides a continuous source of water for the sprinkler pipes.

[0017] Preferably, the collection box is provided with a cover, and the cover has two states, open and closed, relative to the collection box, and the cover is hinged to the collection box.

[0018] When the cover is closed, it can effectively prevent garbage and dust from spilling out during cleaning and transportation. This ensures that the sweeper will not be shaken or tilted when moving, causing garbage and dust to scatter, keeping it clean and tidy.

[0019] Preferably, the water spray port is located on a side of the water spray pipe away from the baffle.

[0020] Set the water spray port on the side of the sprinkler pipe away from the baffle to ensure that the water mist can evenly cover the dust.

[0021] Preferably, the plurality of water spray outlets are arranged linearly and equidistantly on the sprinkler pipe.

[0022] Several water spray nozzles are arranged linearly at equal distances to ensure that the water mist evenly covers every part of the lower part of the filter, which helps to evenly suppress the dust, improve the cleaning effect, and make the entire cleaning process more efficient.

[0023] Compared with the prior art, the utility model has the following advantages:

[0024] The utility model is a road sweeper that improves the initial cleaning efficiency by concentrating garbage and dust, and then uses negative pressure suction to quickly and thoroughly remove garbage, significantly improving the cleaning efficiency. The filter and oscillator in the collection box effectively separate large garbage and fine dust, prevent the filter from clogging, and ensure smooth filtration. The sprinkler pipe evenly sprays to suppress dust flying, reduce dust pollution, and reduce health risks when handling garbage. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. In the following detailed description, for ease of explanation, many specific details are described to provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may also be implemented by those skilled in the art without these specific details.

[0037] like Figure 1 As shown, a road sweeper includes a vehicle body 1, on which a cleaning unit 2, a collecting box 3 and a dust suction device 4 are arranged. The vehicle body 1 is divided into a vehicle front 101 and a vehicle body 102. The cleaning unit 2 is located at the vehicle front 101, and the cleaning unit 2 is connected to the vehicle front 101. The collecting box 3 is located at the vehicle body 102, and the collecting box 3 is connected to the vehicle body 102. A dust suction device 4 is arranged between the cleaning unit 2 and the collecting box 3. The cleaning unit 2 is connected to the collecting box 3 through the dust suction device 4, and the dust suction device 4 is connected to the vehicle front 101 and the vehicle body 102.

[0038] The cleaning unit 2 is located at the front of the vehicle 101 and is responsible for cleaning the road surface and collecting garbage and dust in one place. This is the first step in the whole cleaning process to ensure that garbage and dust are effectively gathered.

[0039] like Figure 2 As shown, the cleaning unit 2 includes two extension arms 201, two cleaning discs 202 and a cleaning roller 203. The two extension arms 201 are arranged at the front of the vehicle head 101, one end of the extension arm 201 is connected to the vehicle head 101, and the other end of the extension arm 201 is arranged with a cleaning disc 202, and the cleaning disc 202 is connected to the extension arm 201. A cleaning roller 203 is arranged at the bottom of the vehicle head 101, and the cleaning roller 203 is connected to the vehicle head 101.

[0040] The cleaning disc 202 sweeps the garbage and dust on the ground to the central area of ​​the cleaning unit 2 through rotational motion, which is convenient for subsequent dust suction and collection. The extension arm 201 can extend the cleaning disc 202 to the cleaning area, so that the cleaning vehicle can cover a wider range. This helps the cleaning vehicle to flexibly adjust the cleaning range during operation to adapt to different road widths and shapes. The cleaning roller 203 is located at the bottom of the vehicle head 101, and it can further collect the garbage and dust swept to the central area by the cleaning disc 202 through rotational motion and move it backwards to make it close to the entrance of the dust suction device 4.

[0041] Then, the dust suction device 4 uses the negative pressure principle to suck the garbage and dust collected by the cleaning unit 2 into the collection box 3 for collection. The efficient operation of the dust suction device 4 ensures that the garbage and dust can be sucked away quickly and thoroughly, thereby improving the cleaning efficiency.

[0042] like Figure 3-Figure 7 As shown, a filter screen 5 is arranged in the collection box 3, and fixed plates 6 are arranged at both ends of the bottom of the filter screen 5. The fixed plate 6 and the filter screen 5 are an integral structure. Several vibration dampers 7 are arranged between the fixed plate 6 and the collection box 3, and the vibration dampers 7 are connected to the fixed plate 6 and the collection box 3. An oscillator 8 is arranged on the side of the fixed plate 6 away from the vibration damper 7, and the oscillator 8 is connected to the filter plate. A baffle 9 is arranged on the side of the oscillator 8 away from the fixed plate 6, and the baffle 9 is an integral structure with the filter screen 5. A sprinkler pipe 10 is arranged on the side of the baffle 9 away from the oscillator 8, and the sprinkler pipe 10 is connected to the baffle 9. Several water spraying ports 11 are arranged on the surface of the sprinkler pipe 10, and the water spraying ports 11 are located on the side of the sprinkler pipe 10 away from the baffle 9. Several water spraying ports 11 are arranged linearly at equal distances on the sprinkler pipe 10, and the water spraying ports 11 are connected to the sprinkler pipe 10.

[0043] The output end of the dust collecting device 4 is located on the upper part of the filter screen 5. Since the output end of the dust collecting device 4 is located on the upper part of the filter screen 5, garbage and dust can be quickly intercepted and separated by the filter screen 5, reducing the retention time of impurities in the collection box 3.

[0044] The garbage and dust entering the collection box 3 will first fall on the filter screen 5, and the vibrator 8 is installed at the bottom of the filter screen 5, so that the filter screen 5 is vibrated by the vibration generated by the vibrator 8. During the vibration process, larger garbage will be left on the upper part of the filter screen 5, while finer dust will fall on the lower part of the filter screen 5 through the vibration. This process not only improves the separation effect of garbage and dust, but also prevents the filter screen 5 from being blocked, ensuring the smooth progress of the filtering process.

[0045] In order to further suppress dust, the sprinkler pipe 10 sprays water mist through the water nozzles 11 installed on its surface. The water nozzles 11 are set on the side of the sprinkler pipe 10 away from the baffle 9 to ensure that the water mist can evenly cover the dust. Several water nozzles 11 are arranged linearly at equal distances to ensure that the water mist evenly covers every part of the lower part of the filter 5, which helps to evenly suppress the dust, improve the cleaning effect, and make the entire cleaning process more efficient. The water mist evenly sprayed by the sprinkler pipe 10 effectively suppresses the dust at the bottom of the filter 5, thereby preventing dust from flying during the subsequent treatment of garbage and dust. This not only helps to keep the air fresh and reduce dust pollution, but also greatly reduces the health risks of workers when handling garbage.

[0046] The vehicle body 102 is provided with a water tank 12, which is connected to the vehicle body 102 and communicated with the sprinkler pipe 10. The water tank 12 can provide a continuous water source for the sprinkler pipe 10.

[0047] The collection box 3 is provided with a cover 13, which has two states, open and closed, relative to the collection box 3, and is hinged to the collection box 3. When the cover 13 is in the closed state of the collection box 3, it can effectively prevent garbage and dust from spilling out during the cleaning and transportation process. This ensures that the sweeper will not be scattered due to vibration or tilting when moving, and keeps it clean and tidy.

[0048] The implementation principle of the utility model road sweeper is:

[0049] The cleaning unit 2 is located at the front of the vehicle 101 and is responsible for cleaning the road surface and collecting the garbage and dust in one place. This is the first step in the entire cleaning process to ensure that the garbage and dust are effectively collected. Next, the dust suction device 4 uses the negative pressure principle to suck the garbage and dust collected by the cleaning unit 2 into the collection box 3 for collection. The efficient operation of the dust suction device 4 ensures that the garbage and dust can be sucked away quickly and thoroughly, thereby improving the cleaning efficiency.

[0050] The garbage and dust entering the collection box 3 will first fall on the filter 5, and the vibrator 8 is installed at the bottom of the filter 5, so that the filter 5 is vibrated by the vibration generated by the vibrator 8. During the vibration process, larger garbage will be left on the upper part of the filter 5, while finer dust will fall on the lower part of the filter 5 through the vibration. This process not only improves the separation effect of garbage and dust, but also prevents the filter 5 from being blocked, ensuring the smooth progress of the filtering process.

[0051] In order to further suppress dust, the sprinkler pipe 10 sprays water mist through the water spray port 11 installed on its surface. The water mist evenly sprayed by the sprinkler pipe 10 effectively suppresses the dust under the filter 5, thereby preventing dust from flying in the subsequent treatment of garbage and dust. This not only helps to keep the air fresh and reduce dust pollution, but also greatly reduces the health risks of workers when handling garbage.

[0052] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the method and core ideas of the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
