[0044] The turning assembly is used to turn over the trash can so that the trash can is turned into the cleaning chamber 1a through the inlet 1b and is inverted outside the inner cleaning assembly or turned out of the cleaning chamber 1a through the inlet 1b.

[0045] Specifically, like Figure 1 、 Figure 3 and Figure 4As shown, the outer cleaning assembly includes two outer cleaning pipelines 2, and the outer cleaning pipelines 2 are fixedly arranged. The two outer cleaning pipelines 2 are arranged in front and back and do not block the above-mentioned inlet 1b, so as to ensure that the garbage can is smoothly flipped into or flipped out of the cleaning cavity 1a. The outer cleaning pipeline 2 is composed of a water inlet section 2a and a water outlet section 2b which are connected and both are tubular. One end of the water inlet section 2a extends out of the cleaning cavity 1a. The water outlet section 2b is in the shape of an inverted U. One end of the water outlet section 2b is connected to the other end of the water inlet section 2a, and the other end of the water outlet section 2b is closed. The two water outlet sections 2b are arranged side by side and are respectively located at the front side and the rear side of the inner cleaning assembly. The outer wall of the water outlet section 2b surrounds an avoidance cavity 2c in the shape of an inverted U. The horizontal axis of the avoidance cavity 2c is parallel to the horizontal axis of the inlet 1b. The size of the avoidance cavity 2c is larger than that of the inlet 1b. The inlet 1b is arranged opposite to the avoidance cavity 2c. At this time, the water outlet section 2b at the front side does not block the inlet 1b. A plurality of outer nozzles 3 are installed on each water outlet section 2b. The spray coverage area formed by the plurality of outer nozzles 3 covers the outer wall of the garbage can.

[0046] A sufficient number of outer nozzles 3 are installed on the water outlet section 2b. The spray coverage area formed by the plurality of outer nozzles 3 completely covers the outer wall of the garbage can. Therefore, only the outer cleaning pipeline 2 needs to be fixedly arranged during actual installation. The structure is simple, and the operation is stable. Preferably, a plurality of outer nozzles 3 are installed at both ends of each water outlet section 2b. The plurality of outer nozzles 3 at the same end of the water outlet section 2b are vertically and uniformly distributed. The water outlet port of each outer nozzle 3 faces the inner cleaning assembly.

[0047] As shown in the drawings, Figure 4 Further, the water outlet section 2b is composed of a horizontal pipe 2b1 and two vertical pipes 2b2 for installing the outer nozzles 3.

The lower end of the vertical pipe 2b2 corresponding to the water inlet section 2a is rotatably inserted into the other end of the water inlet section 2a and sealingly and fixedly connected. Preferably, the vertical pipe 2b2 and the water inlet section 2a are welded and fixedly connected. The outer side wall of the vertical pipe 2b2 forms a seal with the inner wall of the water inlet section 2a through a sealing ring. During actual installation, the spray angle of the outer nozzle 3 is adjusted by rotating the two vertical pipes 2b2. After adjustment is completed, the two vertical pipes 2b2 are fixed. The adjustment is convenient.

The inner cleaning pipeline 5 extends out of the cleaning cavity la at one end, and the other end of the inner cleaning pipeline 5 is a straight pipe-shaped drainage part 5a. The drainage part 5a is vertically arranged, and an inner nozzle 7 is mounted on the upper end of the drainage part 5a. In the actual product, the inner nozzle 7 is vertically arranged, the spray port of the inner nozzle 7 faces upward, and the water inlet section 2a of the inner nozzle 7 is threadedly connected to the inner upper end of the drainage part 5a. The frame 6 is provided with a driving part and a hollow shaft 8.

[0058] The rotating shaft 19 is provided with two clamping arms 20 which are strip-shaped and left-right symmetrical, and the clamping arms 20 have two ends, i.e. a first end and a second end. The second end of the clamping arm 20 is hinged to the rotating shaft 19 through a shaft 21 so that the clamping arm 20 can swing left and right. The first ends of the two clamping arms 20 form a clamping opening 22 for clamping the garbage can, and rotating the rotating shaft 19 can make the first ends of the clamping arms 20 extend into or out of the cleaning cavity 1a through the above-mentioned inlet 1b.

A driving mechanism is arranged at the position of the inlet 1b or outside the cleaning cavity 1a. When the rotating shaft 19 rotates counterclockwise to the position where the first ends of the clamping arms 20 extend out of the cleaning cavity 1a, the driving mechanism will push the two clamping arms 20 to move away from each other against the torsional force of the respective torsional springs 23, and the driving mechanism will release the action on the clamping arms 20 when the rotating shaft 19 rotates clockwise. Preferably, the driving mechanism is arranged at the position of the inlet 1b to reduce the protrusion of the cleaning vehicle.

[0059] The use process is as follows: initially, the two clamping arms 20 move away from each other under the action of the driving mechanism to expand the clamping opening 22, then the garbage can is manually pushed into the clamping opening 22, and then the driving mechanism releases the action on the clamping arms 20, so that the two clamping arms 20 move towards each other under the action of the torsional spring 23 to clamp the garbage can, and the garbage can enters the cleaning cavity 1a for cleaning as the rotating shaft 19 rotates clockwise, and then the inner wall and the outer wall of the garbage can are cleaned through the cleaning assembly; after cleaning, the rotating shaft 19 rotates counterclockwise to make the garbage can extend out of the cleaning cavity 1a, and under the action of the driving mechanism, the two clamping arms 20 release the garbage can, and the garbage can is manually taken out, completing a cleaning process.

[0060] During the turnover and cleaning process, the garbage can is always clamped and positioned between the two clamping arms 20, so that it is not necessary to additionally arrange a clamping mechanism in the cleaning cavity 1a in actual use, thereby greatly simplifying the structure of the cleaning vehicle and reducing the cost.

[0061] In this embodiment, As Figure 7 and Figure 9As shown, the connection between the clamping arms 20 and the rotating shaft 19 is as follows: two connecting sleeves 24 are sleeved and fixed on the rotating shaft 19, and the two connecting sleeves 24 are respectively opposite to the two clamping arms 20. A slot matching the end of the clamping arm 20 is formed in the side wall of the connecting sleeve 24, the slot is in the shape of a n, and the end of the clamping arm 20 is pivotally connected in the corresponding slot through a shaft 21. Preferably, the shaft 21 is a second bolt, a mounting slot in the shape of a n is formed in the end face of the clamping arm 20, the mounting slot and the slot both include two side walls arranged opposite to each other, the two side walls of the slot are both provided with a connecting hole one through which the rod of the second bolt passes, the two side walls of the mounting slot are provided with a connecting hole two through which the rod of the second bolt passes, and a pressure cap is screwed on the rod of the second bolt, and the head of the second bolt and the pressure cap are respectively pressed against the opposite side faces of the two side walls of the slot.

[0062] Two torsion springs 23 are respectively arranged in the two mounting slots, and the two ends of the torsion spring 23 are respectively fixedly connected to the corresponding connecting sleeve 24 and the corresponding clamping arm 20. In the actual product, the torsion spring 23 is a stainless steel double torsion spring 23, and the torsion of the torsion spring 23 is greater than 10 N·m, so as to basically meet the clamping of the plastic environment-friendly garbage can on the market.

[0063] As shown in Figure 7 and Figure 8 The driving mechanism is two driving seats 25 fixed on the carriage 1 and arranged side by side, the driving seat 25 has a wedge-shaped block 25a, and the two wedge-shaped blocks 25a are symmetrically arranged. The end side wall of the two clamping arms 20 is rotatably provided with a rolling element 26 with a circular peripheral surface, the two rolling elements 26 are between the two clamping arms 20, and the outer side faces of the two rolling elements 26 are respectively pressed against the inclined surfaces of the two wedge-shaped blocks 25a by rotating the rotating shaft 19. The rolling elements 26 are rolled on the inclined surfaces of the wedge-shaped blocks 25a to drive the two clamping arms 20 to move closer to or away from each other, so as to realize the clamping or loosening of the garbage can by using a pure mechanical structure. Not only the structure is simple and the work is stable, but also the cost can be further reduced.

[0064] Among them, the rolling element 26 is a roller, and the roller is installed on the corresponding clamping arm 20 through a connecting shaft. Naturally, the rolling element 26 can also be a rolling bearing, the clamping arm 20 is fixedly provided with a positioning shaft matched with the rolling bearing, the inner ring of the rolling bearing is sleeved and fixed on the positioning shaft, and the outer ring of the rolling bearing is used to contact the inclined surface of the wedge-shaped block 25a.

With the cooperation of the screw 27 and the two hanging rings 20a, the moment of inertia of the cross section of the clamping arm 20 at the position of the rolling element 26 is increased, so as to improve the torsional resistance at this position and ensure the stable operation of the clamping arm 20.

[0066] The rotating shaft 19 further comprises a limiting piece, which is located between the two ends of the clamping arms 20, and is used to limit the depth of the garbage can inserted into the clamping opening 22, so that the garbage can is pushed into place at one time, which is convenient for use. Specifically, the limiting piece comprises a long limiting block 28a, which is arranged towards the clamping opening 22, and can abut against the outer side wall of the garbage can to block the garbage can from continuing to extend into the clamping opening 22, which has the advantages of simple structure and stable operation. In the actual product, when the first end of the clamping arm 20 is outside the cleaning cavity 1a, the length of the limiting block 28a extends up and down, the limiting block 28a is arranged obliquely, and the upper end of the limiting block 28a is located further back than the lower end of the limiting block 28a, so that the limiting block 28a is more fitted to the outer side wall of the garbage can.

[0067] Further, the limiting piece further comprises a locking piece 30, a T-shaped blocking frame 28, and a seat 29 fixed to the rotating shaft 19. The seat 29 has a mounting hole through which the rotating shaft 19 passes, and the seat 29 is sleeved and fixed on the rotating shaft 19 through the mounting hole. The blocking frame 28 comprises a head portion and a rod portion, and the head portion is the above-mentioned limiting block 28a, the rod portion of the blocking frame 28 is arranged on the seat 29 in the radial direction of the rotating shaft 19, and the distance between the limiting block 28a and the clamping opening 22 can be adjusted by sliding the blocking frame 28, and the above-mentioned locking piece 30 locks the blocking frame 28 in the sliding position. With the above design, the position of the limiting block 28a can be easily adjusted, which is convenient for debugging.

The first bolt is used for locking the stopper 28 and is matched with the sliding groove 28b to form a sliding fit between the stopper 28 and the seat body 29, and has the advantages of simple structure and convenient assembly. Preferably, the rod part of the stopper 28 is also in the form of a piece. The limiting members are two and are distributed along the axial direction of the rotating shaft 19.

[0069] In the actual product, the cleaning cavities 1a are two and are arranged side by side along the length direction of the cleaning trolley. The equipment cavity 1d is between the two cleaning cavities 1a. The turnover mechanism, the cleaning mechanism and the water pump 12 are all two and are arranged correspondingly to the two cleaning cavities 1a.
