DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-8 , the present invention provides the following technical solutions: Embodiment 1

[0030] In this embodiment, in order to solve the problems existing in the prior art, the following solutions are disclosed, specifically: Figure 1-3As shown, it includes a shell 1 and a bracket at the top thereof for connecting to a cleaning device, a cleaning component is installed at an equal angle at the bottom edge of the shell 1, and a suction pipe 3 for sucking out dirt is arranged at the center of the shell 1, wherein a driving mechanism is installed on the top of the shell 1 to drive the cleaning component to rotate and clean the road, and the cleaning component is composed of an elastic arc-shaped strip 2, wherein the upper surface of the arc-shaped strip 2 is an edge protrusion structure, and a groove 6 distributed along the center line of the arc-shaped strip 2 is opened at the center of the upper surface, wherein the arc-shaped strip 2 is fixed at the edge of the disc covered by the opening at the bottom end of the shell 1, and the groove 6 is connected with the internal space of the basin body 7 through the opening arranged at the top end of the arc-shaped strip 2, and the basin body 7 and the disc at the bottom end of the shell 1 are synchronously rotated by the rotation of the rotating shaft 10, and the driving mechanism can be a motor or other transmission mechanism for driving the rotation. The shaft 10 rotates. When the shaft 10 is in a clockwise rotation state, the basin body 7, the disc and the arc strip 2 all rotate clockwise. In this rotation, the bottom end of the arc strip 2 is attached to the road surface, and its function is to clean thicker dust or fallen leaves, etc., wherein the dust will be sucked out through the suction tube 3, and the fallen leaves will be removed through the subsequent adsorption equipment. At the same time, the driving mechanism can also be used to drive the shaft 10 to rotate counterclockwise. In this rotation, the arc strip 2 is in a high-speed rotation state, and the stones on the road surface and other impurities that are difficult to be handled by the adsorption equipment will enter the groove 6 accordingly. And because the arc strip 2 is in a high-speed rotation state and under the joint influence of the friction between the stones and the inner wall of the groove 6, the stones will move along the distribution trajectory of the arc strip 2 in the groove 6 and finally enter the basin body 7 through the opening at the top of the groove 6 to complete the collection.

[0031] In this embodiment, in order to normally drive the rotating shaft 10 to rotate and clean the basin 7 for collecting dirt at the same time, the following scheme is also disclosed. Figure 5 As shown, the driving mechanism includes a vertical shaft 8 and a motor 1 for driving the vertical shaft 8 to rotate, wherein the vertical shaft 8 is vertically installed in the housing 1 and the device box 4, and the device box 4 is arranged at the top of the housing 1, wherein the vertical shaft 8 is connected to the rotating shaft 10 through two mutually meshing first gears 9, and a cleaning plate 23 is installed at the bottom end of the vertical shaft 8, the cleaning plate 23 extends to the edge of the inside of the basin body 7, and cleans the inner wall of the basin body 7 through the bristles on the side of the cleaning plate 23, and the motor 1 can drive the vertical shaft 8 to rotate synchronously when rotating, so under the meshing transmission of the first gear 9, the rotating shaft 10 will be synchronously in a rotating state and drive the basin body 7 and other components to rotate, at the same time, the vertical shaft 8 will also synchronously drive the cleaning plate 23 to rotate inside the basin body 7, because the basin body 7 rotates around the axis of the rotating shaft 10, and the cleaning plate 23 rotates around the axis of the vertical shaft 8, adopting this design scheme, the inner wall of the basin body 7 can be more efficiently and comprehensively cleaned without the cleaning plate 23 rotating around the rotating shaft 10.

[0032] Since the new energy road cleaning equipment itself has a high load-bearing capacity, and although the power of the new energy equipment is sufficient, its durability is poor compared to fuel / gas equipment, the power source for the operation of the cleaning structure needs to be provided by the new energy power supply device of the cleaning equipment, so the cleaning structure should reduce energy consumption as much as possible while ensuring the cleaning effect. Therefore, in order to solve this problem, the following solution is disclosed in this embodiment, specifically as follows: Figure 5 As shown, the housing 1 is also provided with a conveyor 5 located on the side of the rotating shaft 10, and the interior of the conveyor 5 is provided with an auger plate 17 installed on the shaft, and the shaft is connected to the output shaft of the motor 2 through two mutually meshing bevel teeth, and the bottom end of the auger plate 17 is located at the bottom end of the basin 7, and the auger plate 17 discharges the impurities in the basin 7 into a designated storage container by rotating, and the straw 3 is installed at the bottom end of the rotating shaft 10 and rotates synchronously with the rotating shaft 10, and the straw 3 passes through the hollow structure in the rotating shaft 10 and the negative The negative pressure device is connected to the rotation of the vertical shaft 8 to produce a negative pressure effect. The negative pressure mechanism includes an air pipe 16 and a blow pipe 15. The bottom end of the air pipe 16 is connected to the rotating shaft 10, and the vertical part of the air pipe 16 coaxial with the rotating shaft 10 is connected to the top of the blow pipe 15 distributed obliquely. The bottom end of the blow pipe 15 is connected to the air supply mechanism. The air supply mechanism blows an oblique high-speed airflow toward the air pipe 16 through the blow pipe 15, and the input end of the air pipe 16 is in a negative pressure state through the Venturi principle. The air supply mechanism It includes a first fan blade 12 and a second fan blade 14, both of which are located inside the device box 4, and the first fan blade 12 is unidirectionally rotatably installed on the vertical shaft 8 through the vertical cylinder 11, and the fan shaft of the second fan blade 14 is connected to the vertical shaft 8 through two mutually meshing second gears 13, wherein the second gear 13 and the fan shaft are unidirectionally rotatably connected, when the motor drives the vertical shaft 8 to rotate clockwise, the vertical cylinder 11 will also rotate synchronously and drive the first fan blade 12 to be in a rotating state, at this time the second fan blade 14 will not rotate, so the airflow generated by the rotation of the first fan blade 12 will enter the blowpipe 15 without interference, and continue to blow into the air pipe 16, so that the bottom end of the air pipe 16 and the suction pipe 3 are both in a negative pressure state, completing the adsorption and discharge treatment of dust within the coverage range of the cleaning structure, and when the vertical shaft 8 rotates counterclockwise, the vertical cylinder 11 stops rotating and the second fan blade 14 will be in a rotating state, so whether the vertical shaft 8 rotates clockwise or counterclockwise, it will continue to generate airflow, thereby achieving the purpose of using the same motor to achieve cleaning and generating wind power.

[0033] In this embodiment, in order to further improve the conveying capacity of the auger board 17 and improve the surface cleaning effect of the auger board 17, the following scheme is also disclosed, specifically: Figure 5 and Figure 7As shown, the output end of the air pipe 16 is rotatably connected to the top end of the shaft of the auger plate 17, and the air pipe 16 is connected to the internal cavity of the shaft and the auger plate 17, and the upper end surface of the auger plate 17 is provided with an air hole 20. The airflow mixed with dust will eventually enter the interior of the auger plate 17 when flowing in the air pipe 16, and the airflow will eventually be blown out from the air hole 20 opened on the surface of the auger plate 17. In this way, when the auger plate 17 rotates to transport dirt, it can assist in the smooth transportation of dirt by means of airflow push, and at the same time can have a better airflow cleaning effect on the surface of the auger plate 17. Embodiment 2

[0034] In this embodiment, in order to improve the negative pressure adsorption effect of the straw 3 under special conditions, the following scheme is also disclosed. Figure 6 As shown, the middle section of the straw 3 is vertically slidably connected to the bottom end of the rotating shaft 10 through a hose and a spring surrounding the outside of the hose, and the upper end surfaces of the left and right sections of the straw 3 are respectively slidably connected with push rods 19, and the top end of the push rod 19 slides in a guide groove with an inner end inclined upward opened on the lower end surface of the guide block 18, and the guide block 18 is fixed to the lower end surface of the disc. When the disc, the rotating shaft 10 and the straw 3 are in a state of accelerated rotation, the push rod 19 will slide toward the outside due to the centrifugal force, and under the guidance of the guide groove of the guide block 18, the push rod 19 will simultaneously drive the straw 3 to move downward, so when the shell 1 cannot move downward, the straw 3 can be moved downward by increasing the rotation speed, thereby improving the negative pressure adsorption effect.

[0035] In order to further enhance the cleaning effect of the arc strip 2, the following solution is also disclosed in this embodiment. Figure 8 As shown, an elastic extension block 21 is fixed to the bottom end of the arc strip 2, and a vertical through groove 22 is opened in the extension block 21. When the cleaning structure is in normal use, the bottom end of the arc strip 2 will fit on the road surface. When the downward pressure is large, it will cause the extension block 21 to fork around the through groove 22 to achieve a larger coverage area, which can improve the efficiency of the arc strip 2 in cleaning dust or stones. At the same time, convex thorns are provided on the back, front or both sides of the extension block 21, which can tear and crush the fallen leaves when cleaning them, thereby preventing the fallen leaves or other flaky dirty materials from sticking to the road surface and being difficult to adsorb and process.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
