Description

Technical Field

[0001] This utility model belongs to the technical field of environmental sanitation and cleaning equipment, and in particular relates to a main brush device and a road cleaning vehicle. Background Technology

[0002] With social development, road cleaning equipment (such as road sweepers) has gradually replaced manual cleaning as the mainstream method of cleaning roads or grounds.

[0003] Most commercially available road sweeping equipment uses a main brush, and often it is paired with at least two side brushes to complete the road sweeping. For example, Chinese Patent CN201820777676.5 discloses a road sweeping vehicle, which discloses a main brush mechanism set at the left and right center lines at the bottom of the vehicle frame and a side brush mechanism set at the front of the vehicle frame, and discloses the main brush through hole structure and the sweeping box structure. Those skilled in the art know that the main brush through-hole is the entrance to the sweeping box housing. When the main brush rolls, it sweeps and carries garbage into the sweeping box through the through-hole. After a period of use, the main brush will wear down and its diameter will decrease. It is necessary to adjust the position of the main brush to achieve the optimal sweeping position. To meet the sweeping adjustment needs, commercially available road sweepers currently use adaptive raising / lowering of the distance between the main brush and the ground. However, this method has the following shortcomings: After the main brush wears down, the distance between it and the ground increases. While the distance can be adjusted by controlling the main brush to lower, when the main brush wears down to a certain extent, the gap between the main brush and the rear side of the through-hole becomes relatively large. During the process of the main brush sweeping and carrying garbage into the sweeping box, garbage / dust may leak out, meaning that some garbage / dust falls back to the ground through the gap, resulting in incomplete cleaning and affecting the road cleaning effect. In this case, a new main brush needs to be replaced to continue cleaning. Summary of the Invention

[0004] The purpose of this utility model is to provide a main brush device and a road cleaning vehicle to prevent some garbage / dust from falling back onto the road surface / ground due to wear of the main brush, thus avoiding missed sweeping and achieving a good road cleaning effect.

[0005] This utility model is achieved through the following technical solution: A main brush device, comprising: The main brush body is used for rolling and sweeping garbage on the ground. The main brush body includes a strip-shaped main brush and a rotating shaft, with the rotating shaft located in the middle of the strip-shaped main brush. The box shell has a main brush through hole at the bottom front end. The strip main brush is set in the main brush through hole and the upper part of the strip main brush is covered by the box shell. Side plates are set on both sides of the front end of the box shell. The two ends of the rotating shaft are supported on the side plates by the mounting mechanism. The waste collection part is set in the rear end interior area of ​​the box shell. A square tube is set at the bottom of the box shell between the main brush through hole and the waste collection part. The guiding mechanism is used to guide garbage into the garbage collection section. The guiding mechanism includes a movable plate, an adjuster, and an arc plate. The movable plate is set inside the housing. The adjuster is used to adjust the distance between the movable plate and the main brush. The arc plate is located inside the main brush through hole and is set at the front end of the square tube.

[0006] Furthermore, the guiding mechanism also includes a base plate, which is connected to the bottom of the curved plate and the bottom of the square tube, respectively.

[0007] Furthermore, the bottom of the container shell at the waste collection section is provided with a rectangular frame, which is connected to a square tube. The rectangular frame has through holes, and a sealing plate for opening or closing the through holes is detachably connected to the rectangular frame.

[0008] Furthermore, the rectangular frame is provided with grooves on both sides of the through hole, and the two ends of the sealing plate are slidably set in the two grooves respectively.

[0009] Furthermore, one end of the two chutes is connected by a baffle.

[0010] Furthermore, the mounting mechanism includes a bearing housing, a connector, and a mounting section. The bearing housing contains a bearing, and both ends of the rotating shaft are supported on the bearings. The mounting section is connected to the side plate via the connector.

[0011] Furthermore, the connector includes a connecting bolt and a connecting nut. The mounting part has two elongated holes spaced apart and inclined. The side plate has two mounting holes corresponding to the two elongated holes. The mounting part is connected to the side plate by the connecting bolt passing through the corresponding mounting holes and elongated holes and being screwed to the connecting nut.

[0012] This utility model also provides a road cleaning vehicle, including a vehicle body, a control device, a drive mechanism, a transmission mechanism, a side brush mechanism, and a main brush device as described above. The control device is used to control the operation of the drive mechanism and the side brush mechanism, and the drive mechanism is used to drive the transmission mechanism and drive the rotating shaft of the main brush device to rotate, so as to realize the main brush body to perform rolling cleaning.

[0013] Compared to existing technologies, the advantages of this invention are as follows: When the main strip brush experiences significant wear, a large gap will appear between the main strip brush and the rear side of the main brush through-hole. The distance between the movable plate and the main brush can be adjusted by the adjuster, allowing the movable plate to cover the gap and guide the debris swept up by the main brush into the debris collection section. This prevents some debris / dust from falling back onto the surface / ground due to brush wear, thus avoiding missed cleaning. Furthermore, an arc-shaped plate is added to the bottom rear side of the main brush through-hole. Even if some debris / dust falls back onto the surface / ground through the gap, the arc-shaped plate can scoop it back into the main brush through-hole, and then the main strip brush can sweep this debris / dust back into the debris collection section, further preventing some debris / dust from falling back onto the surface / ground from the rear side of the main brush through-hole, resulting in excellent road cleaning performance.

[0021] Please see Figures 1 to 3 , Figure 1 This is a cross-sectional view of the main brush device of this utility model. Figure 2 This is a top view of the main brush device of this utility model. Figure 3 for Figure 2AA sectional view. A main brush device includes a main brush body, a housing 3, and a guiding mechanism 5. The main brush body is used for rolling and sweeping ground debris. The main brush body includes a strip-shaped main brush 1 and a rotating shaft 2. The rotating shaft 2 is located in the middle of the strip-shaped main brush 1. The bottom front end of the housing 3 is provided with a main brush through hole 32. The strip-shaped main brush 1 is placed in the main brush through hole 32 and its upper part is covered by the housing 3. Side plates 31 are provided on both sides of the front end of the housing 3. The two ends of the rotating shaft 2 are supported on the side plates 31 by mounting mechanisms 6. A debris collection part 33 is provided in the rear end interior area of ​​the housing 3. A square tube 7 is provided in the bottom of the housing 3 between the main brush through hole 32 and the debris collection part 33. The guiding mechanism 5 is used to guide debris into the debris collection part 33. The guiding mechanism 5 includes a movable plate 51, an adjuster, and an arc plate 52. The movable plate 51 is placed in the housing 3. The adjuster is used to adjust the distance between the movable plate 51 and the main brush. The arc plate 52 is located in the main brush through hole 32 and is placed at the front end of the square tube 7.

[0022] It should be explained in detail here that the strip main brush 1 is a strip cylindrical brush. The distance between the movable plate 51 and the strip main brush 1 refers to the distance between the edge of the movable plate 51 and the edge of the bristles of the strip main brush 1. When the strip main brush 1 is worn, the bristles of the strip main brush 1 will become shorter, and a larger gap will be formed between the strip main brush 1 and the upper rear part of the main brush through hole 32. The distance between the edge of the bristles of the strip main brush 1 and the edge of the movable plate 51 will increase, resulting in a large gap. This will cause some garbage / dust to fall back to the ground through the gap during sweeping, resulting in missed sweeping. Therefore, sanitation workers / users can adjust the gap between the movable plate 51 and the strip main brush 1 by adjusting the regulator, so that the movable plate 51 covers the top of the gap. The movable plate 51 guides the garbage swept up by the strip main brush 1 into the garbage collection part 33, preventing some garbage / dust from falling back to the ground due to the wear of the main brush and causing missed sweeping. Simultaneously, an arc-shaped plate 52 is added to the bottom rear side of the main brush through-hole 32. One end of the arc-shaped plate 52 is flush with the front end of the rectangular frame 4, and the bottom of the other end is flush with the bottom of the rectangular frame 4. The outer arc surface of the arc-shaped plate 52 faces the rectangular frame 4. The arc-shaped plate 52 can reduce the gap between the strip main brush 1 and the bottom rear side of the main brush through-hole 32. Even if some garbage / dust falls back to the ground through the gap between the movable plate 51 and the strip main brush 1, the arc-shaped plate 52 can scoop the fallen garbage / dust back into the main brush through-hole. Then, the strip main brush 1 sweeps the garbage / dust back to the garbage collection part, thereby further preventing some garbage / dust from falling back to the ground through the rear side of the main brush through-hole 32 and causing missed sweeping. It has a good road cleaning effect. In this embodiment, the connection structure between the movable plate 51, the adjuster and the side plate 31 can be referred to Chinese Patent CN202220807022.9, and will not be described again here.

[0023] In this embodiment, the waste collection unit 33 can be a separately formed waste bin installed inside the shell 3. Preferably, the waste bin is a pull-out type as used in the prior art, but it can also be integrally formed inside the shell 3. Specifically, in one embodiment, a rectangular frame 4 is provided at the bottom of the waste collection unit 33 within the shell 3. The rectangular frame 4 is connected to a square tube 7. A through hole 41 is provided on the rectangular frame 4, and a sealing plate for opening or closing the through hole 41 is detachably connected to the rectangular frame 4. During cleaning, the through hole 41 is closed by the sealing plate. When waste needs to be discharged, the through hole 41 is opened, allowing the waste in the waste collection unit 33 to be discharged through the through hole 41 on the rectangular frame 4. In one embodiment, a sliding groove 42 is provided on both sides of the through hole 41 on the rectangular frame 4. The two ends of the sealing plate are slidably disposed within the two sliding grooves 42. The sliding groove 42 is an L-shaped plate, and the sealing plate is slidably disposed on the horizontal section of the L-shaped plate, thus sliding on the rectangular frame 4 via the sliding groove 42, facilitating the opening or closing of the through hole 41 by the sealing plate. In one embodiment, one end of the two chutes 42 is connected by a baffle 43. The baffle 43 is used to determine the position of the sealing plate, ensuring that the sealing plate completely closes the through hole 41 and prevents garbage from falling in. In one embodiment, the sealing plate is provided with a handle. This allows sanitation workers / users to pull the sealing plate along the chutes 42.

[0024] In one embodiment, the guiding mechanism 5 further includes a base plate 53, which is connected to the bottom of the arc-shaped plate 52 and the bottom of the square tube 7, respectively. The base plate 53 strengthens the connection between the arc-shaped plate 52 and the rectangular frame 4, and the arc-shaped plate 52, the square tube 7 and the base plate 53 are roughly connected in a triangular shape, so that the arc-shaped plate 52 can be more firmly fixed on the square tube 7.

[0025] In one embodiment, the mounting mechanism 6 includes a bearing housing 61, a connector, and a mounting part 62. The bearing housing 61 houses a bearing, and both ends of the rotating shaft 2 are supported on the bearing. The mounting part 62 is connected to the side plate 31 via the connector. In one embodiment, the connector includes a connecting bolt and a connecting nut. The mounting part 62 has two elongated holes 63 spaced apart and inclined. The side plate 31 has two mounting holes corresponding to the two elongated holes 63. The mounting part 62 is connected to the side plate 31 by the connecting bolt passing through the corresponding mounting holes and the elongated holes 63 and then screwing it onto the connecting nut. By using the elongated hole 63 and connecting bolts, the strip main brush 1 can be moved downwards, thereby adjusting the distance between the strip main brush 1 and the road surface / ground. This design allows for adaptive adjustment of the distance between the strip roller brush and the road surface / ground, as well as the adaptive adjustment of the gap between the strip roller brush and the front edge of the roller brush through the hole. This allows the strip roller brush to sweep and carry debris into the roller brush cleaner through the gap, ensuring the cleaning effect of the roller brush. It also makes full use of the strip roller brush, increases the service life of the roller brush, reduces its replacement frequency, and thus reduces the cost of use.

[0026] This utility model also provides a road cleaning vehicle, including a vehicle body, a control device, a drive mechanism, a transmission mechanism, a side brush mechanism, and a main brush device as described above. The control device is used to control the operation of the drive mechanism and the side brush mechanism. The drive mechanism is used to drive the transmission mechanism and drive the rotating shaft 2 of the main brush device to rotate, so as to realize the main brush body to perform rolling cleaning. The drive scheme and structure between the vehicle body, control device, drive mechanism, transmission mechanism, and side brush mechanism of this utility model road cleaning vehicle are conventional technical means for those skilled in the art, and will not be described in detail here. Please refer to Chinese Patent CN201820777676.5.
