DETAILED DESCRIPTION

[0027] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail with reference to the drawings as follows:

[0028] Example:

[0029] like Figures 1 to 11 As shown, the utility model provides a green belt cleaning device, including a frame 1, wheels 2, brush rollers 3 and a collection box 4. The frame 1 is telescopically arranged on one side close to the green belt stacking, and the frame 1 is fixedly arranged on the side close to the road surface. The frame 1 on the telescopically arranged side can walk on the stacking, and in the case of uneven terrain, the frame 1 is kept as stable as possible. The wheels 2 are rotatably connected to the bottom of the frame 1. In order to maintain balance, the wheels 2 are arranged as four mutually symmetrical wheels 2. The central axis of the brush roller 3 is coaxially connected to the wheels 2, and the central axis of the brush roller 3 is spaced from the side of the frame 1 telescopically arranged, so as not to hinder the telescopic movement of the frame 1 on this side. The collection box 4 is used to receive the garbage cleaned by the brush roller 3, and the collection box 4 is fixedly connected to the frame 1. The frame 1 is provided with a compression assembly 5 for compressing the collected objects in the collection box 4. The brush roller 3 is coaxially connected with a pushing mechanism 6 for pushing the compression assembly 5 to move into the collection box 4, and the pushing mechanism 6 is movably connected to the compression assembly 5. A placement box 9 is fixedly arranged on the frame 1 , and the compression component 5 is placed in the placement box 9 . The placement box 9 is convenient for taking out and storing the compression component 5 .

[0030] As another example, Figures 1 to 3 As shown, the frame 1 of the present application includes a bracket 11, a telescopic tube 12, a sleeve 13 and a fixed rod 14. The bracket 11 is fixedly connected to the sleeve 13 and the end of the fixed rod 14 away from the ground. The other end of the fixed rod 14 is rotatably connected to the wheel 2. One end of the telescopic tube 12 is rotatably connected to the wheel 2. The other end of the telescopic tube 12 is sleeved in the sleeve 13, and the sleeve 13 and the telescopic tube 12 are elastically arranged. The telescopic tube 12 can move up and down in the sleeve 13. A telescopic spring is arranged between the sleeve 13 and the telescopic tube 12, which can play a supporting role and can also be telescoped. In actual use, in order to make the frame 1 more balanced during operation, a heavy object can be placed on the bracket 11 on one side of the telescopic tube 12, which mainly depends on the application of the telescopic spring. When the supporting force of the telescopic spring is large, a heavy object needs to be placed. When the supporting force of the telescopic spring is small, it is not necessary. It depends on the selection of the telescopic spring.

[0031] The brush roller 3 includes a first brush roller 31 and a second brush roller 32. The vertical cross section of the first brush roller 31 with the fixed rod 14 is a rectangle, and the vertical cross section of the second brush roller 32 with the fixed rod 14 is a trapezoid. The first brush roller 31 is close to the fixed rod 14, and the second brush roller 32 is close to the telescopic tube 12. The diameters of the first brush roller 31 and the second brush roller 32 are both larger than the diameter of the wheel 2, but the diameter of the brush is smaller than the diameter of the wheel 2. The first brush roller 31 is mainly used to clean garbage or leaves near the road side, and the second brush roller 32 can be used to clean garbage and leaves in the drainage ditch due to the inclined surface setting. Since the frame 1 near the drainage ditch is telescopically set, it does not affect the movement of the second brush roller 32, and the brush on the side of the second brush roller 32 near the drainage ditch stacking is perpendicular to the ground, which can clean garbage and leaves in the drainage ditch, and the second brush roller 32 is not connected to the telescopic frame 1, which is also convenient for replacing the second brush roller 32.

[0032] As another example, Figure 4 and Figure 7 As shown, the collection box 4 of the present application includes a bottom plate 41, a side plate 42, a baffle 43, a cover plate 44, a strip 45, a folding sheet 46 and a telescopic strip 47. The collection box 4 is set with an opening on one side close to the brush roller 3. The bottom plate 41 is composed of a plurality of strips 45. A folding sheet 46 is fixedly connected between each strip 45. The folding sheet 46 is made of rubber material and mainly plays a telescopic role. The thickness of the folding sheet 46 after folding is less than the thickness of the strip 45, so as to reduce the friction between the folding sheet 46 and the ground and improve the service life. The folding sheet 46 can also be a plurality of hinged metal sheets. The strip 45 is made of metal material and can be an iron bar or a steel bar. On the one hand, it has enough self-weight to fit the ground. On the other hand, iron bars or steel bars are more wear-resistant than other materials and have lower costs.

[0033] The side plate 42 is composed of two strips 45, and the two strips 45 are staggered up and down. The side plate 42 can be extended and retracted with the change of the terrain. Since the upper part is fixed on the frame 1, the lower part will be extended and retracted with the change of the terrain, that is, the side close to the drainage channel will drop, and the side of the road surface will remain unchanged or rise. The upper part of the baffle 43 is composed of a plurality of strips 45, and a folding piece 46 is fixedly connected between each strip 45. The lower part of the baffle 43 is composed of a plurality of strips 45, and is arranged corresponding to the strips 45 on the upper part of the baffle 43. The upper and lower parts of the baffle 43 are staggered. The inner wall at the edge of the upper part is fixed with a sliding groove, and the lower part can slide in the sliding groove. The strips 45 at the lower part of the baffle 43 correspond to the strips 45 of the bottom plate 41 and are hinged or fixedly connected. The two side edges of the baffle 43 are hinged to the side plates 42, and one side is movably connected. The simplest way is to set locking rings respectively, and the two are movably connected by locking. Of course, they can also be connected by a snap device. The movable connection is mainly convenient for the collection box 4 to unload the internal garbage. The strips 45 at the lower part of the baffle 43 are fixedly connected to the telescopic strips 47. The folding piece 46 can be horizontally telescopic. The telescopic strips 47 are set as elastic ropes and can be telescopic in the up and down directions. On the side of the bottom plate 41 close to the drainage channel, the strips 45 sink, and the strips 45 corresponding to the baffle 43 also sink. The density of the telescopic strips 47 is set according to the actual situation, and the number of strips needs to ensure that the collected materials in the collection box 4 are not exposed. The upper part of the baffle 43 is staggered with the lower part of the baffle 43. The cover plate 44 has the same structure as the bottom plate 41. The upper part of the baffle 43, the upper part of the side plate 42 and the cover plate 44 are fixedly connected to the frame 1. The cover plate 44 can also be a fixed whole plate. After unloading, the collection box 4 can be tightened with a rope or a strip core frame to reduce the friction still caused by friction with the ground after use and improve the service life.

[0034] As another example, Figures 8 to 10As shown, the compression assembly 5 of the present application includes a roller 51, a telescopic rod 52, a spring 53, a stopper 54 and a fixed bar 55. One end of the telescopic rod 52 is fixedly connected to the fixed bar 55, and the other end of the telescopic rod 52 is rotatably connected to the roller 51. A spring 53 is fixedly arranged inside the telescopic rod 52. A plurality of telescopic rods 52 are arranged at equal intervals. The stopper 54 is fixedly connected to the fixed portion of the telescopic rod 52 and is close to one side of the inner wall of the side plate 42. The inner wall of the upper part of the side plate 42 is fixedly connected with a vertical side bar 81 and a horizontal side bar 82 for limiting the pushing mechanism 6. The vertical side bar 81 is arranged below the slit 441, and the horizontal side bar 82 extends to one side of the baffle 43. The stopper 54 slides on the horizontal side bar 82. A plurality of telescopic rods 52 form a grid to squeeze the garbage and leaves in the collection box 4. The telescopic rods 52 can correspond to the change of the sinking of the strip 45 on one side of the drainage channel. The setting of the roller 51 can reduce the friction between the telescopic rod 52 and the collection box 4, making it smoother to push into the collection box 4, and the roller 51 can increase the gravity of the bottom end of the telescopic rod 52 to fit the bottom plate 41 of the collection box 4. The compression assembly 5 is placed into the collection box 4 from the slit 441, and is limited by the vertical side strips 81 and the horizontal side strips 82, which can also keep the compression assembly 5 stable after entering the collection box 4. The closer to the side of the telescopic rod 52, the shorter the width of the strip 45 is, because the closer to the side of the telescopic rod 52, the lower the height of the drainage channel is, and the more deformation of the bottom plate 41 is required to fit the ground.

[0035] As another example, Fig.10 and Fig.11 As shown, the pushing mechanism 6 of the present application includes an active rod 61, a driven rod 62 and a pushing rod 63. One end of the active rod 61 is fixedly connected to the rotating shaft at the connection between the first brush roller 31 and the second brush roller 32, the other end of the active rod 61 is rotationally connected to the driven rod 62, and the other end of the driven rod 62 is rotationally connected to the pushing rod 63. The cover plate 44 is provided with a slit 441 for placing the pushing mechanism 6, the inner wall of the upper part of the side plate 42 is fixedly connected to a limiting rod 71, the side of the limiting rod 71 away from the side plate 42 is fixedly connected to a limiting ring 72, and the distance from the slit 441 to the rotating shaft of the first brush roller 31 or the second brush roller 32 is greater than the shortest distance of the pushing movement of the pushing rod 63. When the wheel 2 rotates, it drives the coaxial first brush roller 31 and the second brush roller 32 to rotate, and at the same time drives the coaxial active rod 61 to rotate. The active rod 61 drives the driven rod 62 to rotate, and the driven rod 62 drives the push rod 63 to slide in the limiting ring 72. The limiting ring 72 can improve the movement stability of the push rod 63. The diameter of the push rod 63 is longer than the diameters of the active rod 61 and the driven rod 62, and has more contact areas with the compression assembly 5, thereby improving the stable push of the compression assembly 5 as much as possible. When garbage and leaves enter the collection box 4, they are affected by gravity and a slope is formed at the entrance. The probability of the push rod 63 pulling out leaves and garbage is not high.

[0036] The working principle of a green belt cleaning device of the present application is as follows: the frame 1 is telescopically arranged near one side of the drainage channel, and can walk on the stack of garbage, leaves, etc. in the drainage channel, and the second brush roller 32 is not connected to the frame 1, which does not affect the rotation and operation of the first brush roller 31 and the second brush roller 32. The first brush roller 31 is horizontally arranged to clean the road surface beside the drainage channel, and the second brush roller 32 with an inclined brush cross-section can clean the inside of the drainage channel. It is also matched with a collection box 4 that can change to adapt to changes in terrain. The collection box 4 is composed of a vertically telescopic side plate 42 and a horizontally telescopic bottom plate 41. When the drainage channel drops relative to the ground, the horizontally telescopic bottom plate 41 drops on one side of the drainage channel and fits with the ground due to its own weight, and the side plate 42 cooperates with the change of the bottom plate 41. Since the opening of the collection box 4 points to the first brush roller 31 and the second brush roller 32, a squeezing device is required to push the collected material to the bottom of the collection box 4 so as to load more collected material. When the collected material in the collection box 4 is full to the slit 441, the compression assembly 5 is taken out from the placement box 9, inserted into the slit 441 and lowered along the vertical side bar 81, and the compression assembly 5 is pushed to the bottom of the collection box 4 by the push rod 63. Multiple compression assemblies 5 can be placed in the placement box 9, and the collection box 4 can be squeezed multiple times. After the collection is completed and the collected material in the collection box 4 is unloaded, the collection box 4 is bounded with a rope or a side bar frame to reduce the friction between the collection box 4 and the ground and increase the service life.

Any technician familiar with the field can make many possible changes and modifications to the technical solution of the present invention by using the above technical content without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
