DETAILED DESCRIPTION

[0024] EMBODIMENT

[0025] COMBINATION Figures 1 to 6As shown, the embodiment provides a garbage cleaning vehicle, which comprises a vehicle body, a garbage collecting device and a centrifugal fan arranged on the vehicle body, and a light ditch cleaning equipment arranged on the vehicle body through a joint type mechanical arm 1 to control the extension or retraction of the composite cleaning device 3 on the vehicle body. The light ditch cleaning equipment comprises the joint type mechanical arm 1, a dust suction interface 2 and the composite cleaning device 3. One end of the joint type mechanical arm 1 is adapted to be connected to the vehicle body, and the other end is connected to the composite cleaning device 3, which is configured to control the extension or retraction of the composite cleaning device 3 on the vehicle body. The composite cleaning device 3 comprises at least two disc-rolling composite cleaning brushes 34 and a connecting plate 31. The disc-rolling composite cleaning brush 34 comprises a rolling brush 342 adapted to clean the side of the ditch and a disc brush 341 arranged below the rolling brush 342 for cleaning the bottom of the ditch. The connecting plate 31 connects the joint type mechanical arm 1 and the two disc-rolling composite cleaning brushes 34, and is adapted to rotate on the joint type mechanical arm 1 to make the two disc-rolling composite cleaning brushes 34 approach the side edges of the ditch, respectively. The dust suction interface is adapted to be connected to a dust suction device, which is arranged at the rear end of the disc-rolling composite cleaning brush 34 and is adapted to suck the garbage cleaned by the disc-rolling composite cleaning brush 34 into the garbage collecting device under the action of the dust suction device.

[0026] In the embodiment, the garbage cleaning vehicle can be modified from an existing garbage truck. The garbage cleaning vehicle mainly comprises a vehicle body, a garbage collecting device and a centrifugal fan arranged on the vehicle body. The centrifugal fan is connected to the composite cleaning device 3 through an air pipe to suck the garbage into the garbage collecting device. Of course, the vehicle body is also provided with a power source connected to the composite cleaning device 3 to provide power for the rotating motor 33 and the rotating motor 32.

[0027] In combination with Figure 2As shown, the articulated mechanical arm 1 comprises a first connecting arm 11, a second connecting arm 12, a third connecting arm 13, a fourth connecting arm 14, a first connecting block 15 and a second connecting block 16, the connecting plate 31 is rotatably fixed on the first connecting block 15 and connected with a rotating motor 32, both ends of the first connecting arm 11 are hingedly connected with the first connecting block 15 and the second connecting arm 12 respectively, the second connecting arm 12 and the second connecting block 16 are hingedly connected with the third connecting arm 13 and the fourth connecting arm 14 which are parallel to each other; the second connecting arm 12 and the first connecting block 15 and the third connecting arm 13 and the vehicle body are respectively hingedly connected with the telescopic device 17. Among them, the second connecting block 16 is fixed on the vehicle body, and the movement of the composite cleaning device 3 in the horizontal direction and the vertical direction is realized by controlling the telescopic device 17. Here, the second connecting arm 12 is of a special shape, and the telescopic device 17 and the first connecting arm 11 have a certain included angle. The telescopic device 17 can use a hydraulic cylinder or a pneumatic cylinder, preferably a hydraulic cylinder, which can provide more power. Further, a fixing clamp 18 is also provided on the second connecting arm 12, which can clamp the air pipe connected with the composite cleaning device 3 to fix the air pipe and improve the stability and simplicity of the mechanism.

[0028] In combination Figures 3 to 4 As shown, the composite cleaning device 3 comprises a connecting plate 31, two disc-roller composite cleaning brushes 34 are arranged below the connecting plate 31, and two rotating motors 33 are arranged above the disc-roller composite cleaning brushes 34 to drive the disc-roller composite cleaning brushes 34 to rotate. Here, the disc-roller composite cleaning brush 34 comprises a disc brush 341 arranged at the bottom and a roller brush 342 located above the disc brush 341, the wide surface of the brush piece on the disc brush 341 is perpendicular to the horizontal plane, and the bottom edge of the brush piece can be arranged to have a certain angle with the horizontal plane; specifically, here the angle can be arranged to be about 120°, at which angle the cleaning effect on the bottom surface is best. The wide surface of the brush piece of the roller brush 342 is parallel to the horizontal plane, and when rotating, the roller brush 342 rotates synchronously with the disc brush 341, the roller brush 342 is used to clean the side edge of the ditch, and the brush piece of the disc brush 341 is used to clean the bottom surface of the ditch. Here, the brush piece can be made of plastic material or other flexible material.

[0029] In combination Figure 3 And Figure 6As shown, in a preferred embodiment, the lower end of the disc-roller composite cleaning brush 34 is provided with a bearing seat 4, the bearing seat 4 is provided with a retainer ring 41, the retainer ring 41 includes a circular retainer edge 411 and an inclined retainer edge 412 inclined relative to the central axis of the bearing seat 4, the circular retainer edge 411 is connected below the bearing seat 4 through the inclined retainer edge 412; here the circular retainer edge 411 can be provided as a sector in the range of 200°-280°, preferably a sector of 240° can be used. Here the bearing seat 4 is relatively fixed relative to the disc-roller composite cleaning brush 34, and the bearing seat 4 is provided with a bearing 42, the opening of the sector is arranged forward, by providing the circular retainer edge 411 with a certain angle of sector, the sundries can be gathered, and the sundry particles on the bottom surface of the ditch are gathered to the suction port 22 at the rear. Further, since the contact angle of the disc brush 341 with the ground is 120°, the cleaning effect is the best, the current market used sanitation sweeper, the method is to adjust the side inclination angle of the disc brush 341 to 4° through the threaded adjusting rod, and then control the forward inclination angle of the disc brush 341 to 4-5° through the inclination adjusting bolt, this scheme has a relatively complex structure, and it is extremely inconvenient to adjust the inclination angle, and in the cleaning work, the violent vibration of the sweeper and the motor will affect the inclination angle, resulting in that in the actual work, the contact angle of the disc brush 341 will fluctuate within a certain range. Therefore, here the circular retainer edge 411 with 240° is provided, the circular retainer edge 411 can lift the brush piece of the disc brush 341 above it, so that only the bristles in the area outside the circular retainer edge 411 will be directly in contact with the bottom surface. That is, only one third of the brush piece outside the circular retainer edge 411 will be directly in contact with the ground during the operation of the device, through this scheme, the ground contact angle of the disc brush 341 can be 120°, and the central axis of the roller brush 342 can be vertical, preventing the problem of incomplete cleaning caused by the hollow part between the two disc-roller composite cleaning brushes 34 due to the non-vertical central axis.

[0030] In combination Figure 2 and Figure 5As shown, the dust suction interface 2 comprises a fan suction port shell 21, the fan suction port shell 21 is provided with a suction port 22 connected with a fan and left and right side plates 23 and 24, the left and right side plates 23 and 24 are respectively close to two disc-roller composite cleaning brushes 34. Here, the dust suction device can be a centrifugal fan (not shown), the centrifugal fan is connected to the suction port 22 through an air pipe (not shown), and the garbage collected by the disc-roller composite cleaning brush 34 is sucked into the garbage collection device. Here, the left and right side plates 23 and 24 are provided for collecting the garbage brushed by the disc-roller composite cleaning brush 34, so as to guide the garbage to the suction port 22. Further, the openings of the left and right side plates 23 and 24 are outwardly arranged, the side plates are located outside the disc-roller composite cleaning brush 34 close to the side plates, and the lengths of the left and right side plates 23 and 24 reach the central axes of the disc-roller composite cleaning brush 34 close to the side plates. Here, since the two disc-roller composite cleaning brushes 34 are arranged in front and back, the lengths of the left and right side plates 23 and 24 are different. Further, inclined surfaces are arranged at the ends of the left and right side plates 23 and 24, the inclined surfaces can also adjust the angle of the connecting plate 31 when the garbage on the side of the ditch cannot be brushed away by the disc-roller composite cleaning brush 34, so that the inclined surfaces are close to the garbage for shoveling, thereby improving the cleaning effect.

[0031] In another preferred embodiment, the first connecting arm 11 is provided with a camera 5 towards the direction of the composite cleaning device 3. The camera 5 is connected to the cab of the vehicle body, so that the driver can observe the close degree of the cleaning brush to the ditch, the diffusion of dust, and the details of the sundries in the ditch at any time, so that the driver can fully master the cleaning condition in the ditch. The monitoring mode is prior art, which will not be described here.

[0032] It should be noted that the fixed connection modes involved in the present application can adopt bolt or screw connection, and the circuit wiring is not the focus of the present application, which will not be described in detail here.

[0033] Through the arrangement of the present application, the existing ditch cleaning device is optimized, the cleaning efficiency can be effectively improved, the cost is low, and the secondary dust pollution can be reduced.
