Detailed implementation manners

[0035] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0036] As Figures 1 to 9 shown, an energy-saving cleaning mechanism of the present invention includes a mounting seat 11, a dust suction component, a rotary brush component and a crushing component.

[0037] The dust collection assembly is provided at the front end of the mounting base 11. The dust collection assembly includes a collection bin 2. A feed inlet 21 is provided at the front end of the collection bin 2, and a first air suction port 22 is provided at the rear end of the collection bin 2. The rotary brush assembly is provided at the rear end of the mounting base 11. The rotary brush assembly includes a rotary brush 31 and a material receiving plate 32. The rotary brush 31 is rotatably provided at the lower end of the mounting base 11, and a first motor 311 for driving the rotary brush 31 to rotate is provided on the mounting base 11. The material receiving plate 32 is provided on the front side of the rotary brush 31. A storage cavity 321 is formed at the upper end of the material receiving plate 32. A second air suction port 33 is provided on the mounting base 11 corresponding to the position of the storage cavity 321. A plurality of traveling wheels 16 for support are provided at the lower end of the mounting base 11.

[0038] During use, the mounting base 11 is installed at the tail of the cleaning vehicle, so that the cleaning structure cooperates with the dustbin 13, the disk brush 14 and the fan 15 on the cleaning vehicle to clean the garbage on the road surface. Specifically, as Figures 1 to 8 shown, during the process of the cleaning vehicle traveling, the garbage on the road surface is collected and conveyed to the front side of the collection bin 2 by the rotation of the disk brush 14, and due to the movement of the cleaning vehicle, this part of the garbage will enter the collection bin 2 through the feed inlet 21 for collection. At the same time, the rotary brush 31 is driven to rotate by the first motor 311, sweeping up the garbage on the ground and pushing it onto the material receiving plate 32. This part of the garbage will be temporarily stored in the storage cavity 321 provided on the material receiving plate 32. After the cleaning vehicle works for a certain period of time, the fan 15 is started, creating a negative pressure inside the collection bin 2 and inside the storage cavity 321. At this time, the garbage collected in the collection bin 2 can be sucked into the dustbin 13 through the first air suction port 22, and at the same time, the garbage collected in the storage cavity 321 can be sucked into the dustbin 13 through the second air suction port 33. Therefore, during the process of cleaning the garbage, the garbage can be temporarily collected inside the collection bin 2 and the storage cavity 321 first, and then the fan 15 is started every once in a while to suck the garbage inside the collection bin 2 and the storage cavity 321 into the dustbin 13, so that the fan 15 can work intermittently, reducing energy consumption and extending the service life of the fan 15.

[0039] The crushing assembly is provided inside the collection bin 2. The crushing assembly includes multiple groups of adapted vertical knives 41 and cutting knives 42. The vertical knives 41 are longitudinally installed inside the collection bin 2. A driving shaft 43 is rotatably installed inside the collection bin 2, and a third motor 431 for driving the driving shaft 43 to rotate is installed on the collection bin 2. The cutting knives 42 are installed on the driving shaft 43. A material deflecting member 44 is installed at the end of each cutting knife 42 away from the driving shaft 43. The material deflecting member 44 includes a rotating shaft 441 and multiple material deflecting teeth 442. The rotating shaft 441 is arranged along the axial direction of the driving shaft 43, and one end is rotatably connected to the end of the cutting knife 42 through a torsion spring. The multiple material deflecting teeth 442 are arranged in an axial array along the rotating shaft 441. In the non-loaded state, the extending direction of the material deflecting teeth 442 is the same as the extending direction of the end of the cutting knife 42.

[0040] Specifically, as Figures 1 to 7 shown, after the garbage enters the collection bin 2, it first comes into contact with the cutting knife 42 installed on the front side. The cutting knife 42 rotates counterclockwise under the drive of the motor three 431, and initially cuts the incoming garbage. At the same time, during the rotation of the cutting knife 42, it can push the garbage backward, causing it to move to the position of the vertical knife 41. When the garbage moves to the position of the vertical knife 41, the vertical knife 41 can further cut the garbage. At the same time, through the staggered cooperation of the vertical knife 41 and the cutting knife 42, a greater cutting force can be provided to ensure that the garbage is completely divided into smaller pieces. By crushing the garbage, it is convenient to subsequently suck this part of the garbage into the garbage bin 13 through the first air suction port 22, and at the same time, it can prevent the first air suction port 22 from being blocked and affecting the normal use of the road sweeper.

[0041] Taking one group of the material pushing members 44 as an example for description, in the initial state, the multiple material pushing teeth 442 on the material pushing member 44 are maintained in state one under the action of the torsion spring, that is, the extending direction of the material pushing teeth 442 is the same as the extending direction of the end of the cutting knife 42. When the cutting knife 42 is driven by the drive shaft 43 to rotate counterclockwise, it can drive the material pushing member 44 provided at the end of the cutting knife 42 to rotate counterclockwise until the end of the material pushing teeth 442 contacts the bottom of the collection bin 2. At this time, as the drive shaft 43 continues to rotate, the material pushing teeth 442 will rotate to state two, that is, a relative rotation occurs between the material pushing teeth 442 and the end of the cutting knife 42, and the torsion spring is twisted to store energy until the end of the cutting knife 42 is perpendicular to the bottom of the collection bin 2. During this process, the angle between the side wall of the material pushing teeth 442 and the bottom of the collection bin 2 gradually decreases, and the garbage in the collection bin 2 can be squeezed by the material pushing teeth 442, so that the soil clods in the garbage can be squeezed and broken, ensuring that the subsequent broken soil clods can be smoothly sucked into the garbage bin 13, and further ensuring the cleaning effect of the garbage; then the drive shaft 43 continues to rotate, and the material pushing teeth 442 will rotate reversely under the action of the torsion spring, so that the angle between the material pushing teeth 442 and the end of the cutting knife 42 gradually increases until the material pushing teeth 442 are perpendicular to the bottom of the collection bin 2, and the material pushing teeth 442 are rotated to state three. At this time, as the drive shaft 43 continues to rotate, the material pushing teeth 442 will quickly reverse under the action of the torsion spring, so that the extending direction of the material pushing teeth 442 is the same as the extending direction of the end of the cutting knife 42. During this process, through the rapid rotation of the material pushing teeth 442, the garbage located behind the material pushing teeth 442 can be pushed and the garbage can be lifted to the position of the first air suction port 22, which is convenient for improving the suction efficiency of the garbage and further improving the cleaning efficiency.

[0042] After the sweeper works for a period of time, the material distributing member 44 may be wound with garbage such as leaves and plastic bags, which affects the normal use of the material distributing member 44. Therefore, in some embodiments, a baffle 45 is provided in the collection bin 2. The baffle 45 is longitudinally arranged at the rear side of the crushing assembly, and a space for garbage to pass through is provided at the lower end of the baffle 45. The material distributing teeth 442 are in a plate-like structure, and a cutting groove 451 adapted to the material distributing teeth 442 is provided at the lower part of the baffle 45. When the driving shaft 43 rotates, the material distributing teeth 442 can pass through the corresponding cutting groove 451 to crush the garbage wound on the material distributing teeth 442.

[0043] Specifically, as Figures 2 to 7 shown, when the driving shaft 43 rotates, it can drive the cutting knife 42 and the material distributing member 44 to rotate synchronously. During this process, the garbage entering the collection bin 2 can be crushed through the cooperation of the cutting knife 42 and the vertical knife 41, and at the same time, the garbage wound on the material distributing teeth 442 can be crushed through the cooperation of the material distributing teeth 442 and the cutting groove 451. When the material distributing teeth 442 are disengaged from the cutting groove 451, the crushed garbage wound on the material distributing teeth 442 will be scraped off by the side wall of the cutting groove 451, effectively preventing the garbage from winding on the material distributing member 44 and ensuring the normal use of the material distributing member 44. In addition, when the garbage wound on the material distributing teeth 442 is scraped off, this part of the garbage is at a relatively high height and can be directly sucked into the garbage bin 13 through the first air suction port 22.

[0044] In some embodiments, the material receiving plate 32 includes a U-shaped part and an arc-shaped part connected to the rear side of the U-shaped part. A groove, namely a storage cavity 321, is formed on the U-shaped part for temporarily storing the garbage swept by the rotary brush 31. The arc surface of the arc-shaped part faces the rotary brush 31 to guide the garbage into the storage cavity 321 and reduce the accumulation of garbage on the material receiving plate 32. Among them, the arc surface design of the arc-shaped part can better adapt to the movement track of the rotary brush 31 to ensure that the garbage can smoothly enter the storage cavity 321.

[0045] In some embodiments, the second air suction port 33 is correspondingly arranged at the middle part of the storage cavity 321. A screw conveyor assembly is installed in the storage cavity 321. The screw conveyor assembly includes a screw shaft 34 and two sections of screw blades 35. The screw shaft 34 is rotatably installed in the storage cavity 321. A second motor 341 for driving the screw shaft 34 to rotate is provided on the mounting seat 11. The two sections of screw blades 35 are reversely installed at both ends of the screw shaft 34, that is, the spiral directions of the two sections of screw blades 35 are opposite.

[0046] Specifically, as Figure 2 、 Figure 8 and Figure 9As shown, when the fan 15 is started, the garbage in the storage chamber 321 can be sucked into the garbage bin 13 through the second suction port 33. During this process, the second motor 341 is started to drive the auger shaft 34 to rotate, and drive the two sections of auger blades 35 to rotate synchronously. Since the spiral directions of the two sections of auger blades 35 are opposite, the garbage in the storage chamber 321 can be conveyed from both ends to the middle, so that the garbage is effectively concentrated in the middle position of the storage chamber 321, so that the second suction port 33 provided in the middle of the storage chamber 321 can suck the garbage, improving the suction efficiency of the garbage.

[0047] In some embodiments, two deflector plates 36 are installed in the middle of the auger shaft 34.

[0048] Specifically, as Figure 8 and Figure 9 shown, when the auger shaft 34 rotates, it can drive the two deflector plates 36 to rotate synchronously. As the deflector plates 36 rotate, the garbage concentrated in the middle position of the storage chamber 321 can be stirred and lifted, assisting the fan 15 to suck, and further improving the suction efficiency of the garbage.

[0049] In some embodiments, two guide plates 23 are provided at the front end of the collection bin 2. The two guide plates 23 are symmetrically arranged in a trumpet shape, and a brush 24 is provided at the lower end of each guide plate 23.

[0050] Specifically, as Figure 2 and Figure 3 shown, the guide plate 23 is used to guide the garbage in front of the collection bin 2 into the collection bin 2. Its trumpet-shaped design can expand the garbage receiving area, reduce the accumulation and blockage of garbage at the feed inlet 21, and ensure that the garbage can smoothly enter the collection bin 2. The brush 24 is used to clean the ground to ensure that the garbage can be collected more thoroughly. The brush 24 is usually made of soft bristles and can effectively clean the dust and small particle garbage on the ground.

[0051] In some embodiments, a baffle 25 is provided at the front end of the collection bin 2. The baffle 25 is inclined downward from top to bottom towards the rear end of the collection bin 2.

[0052] Specifically, as Figure 2 and Figure 5 shown, by setting the inclined baffle 25, the area of the feed inlet 21 can be effectively reduced, the wind speed in the collection bin 2 when the fan 15 is working can be increased, and at the same time, it will not have too much impact on collecting garbage.

[0053] In some embodiments, a plurality of flow dividing members 26 are provided at the bottom of the collection bin 2, and each flow dividing member 26 is provided with a tip.

[0054] Specifically, as Figures 2 to 5As shown, during the process of the material pushing member 44 pushing the garbage, the tips on the flow dividing member 26 can effectively cut and disperse the garbage. Especially for easily entangled garbage such as plastic bags and leaves, it can effectively prevent the accumulation of garbage, ensure that the garbage is evenly distributed and smoothly enters the subsequent treatment process. In addition, during the process of the material pushing member 44 pressing and crushing the soil clods in the garbage, the tips on the flow dividing member 26 can effectively improve the crushing effect on the soil clods.

[0055] In some embodiments, a discharge port 27 is provided at the rear end of the collection bin 2.

[0056] Specifically, as Figures 5 to 7 shown, during the movement of the sweeper, the garbage located in front of the collection bin 2 can enter the collection bin 2. At the same time, some stones will also enter the collection bin 2. When the fan 15 is started, these garbage and stones can be synchronously sucked into the garbage bin 13. For some heavier stones, if the negative pressure provided by the fan 15 is not sufficient to suck up these stones, these stones will gradually accumulate at the rear end of the collection bin 2, forming a slope. After a period of cleaning work, the staff can manually open the discharge port 27 to clean out the stones accumulated in the collection bin 2, so as to avoid too many stones in the collection bin 2 affecting the normal cleaning of the garbage.

[0057] As Figures 1 to 9 shown, the present invention also provides a sweeper, which includes a vehicle body 1 and the above-mentioned cleaning mechanism. The cleaning mechanism is mounted on the tail of the vehicle body 1 and can be lifted up when not in use. The vehicle body 1 is also provided with a water tank 12, a garbage bin 13, a disk brush 14 and a fan 15. For the specific functions and structures of the cleaning mechanism, reference can be made to the above embodiments, and details will not be described here one by one.

[0058] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
