DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example 1: This example 1 provides a garbage cleaning device that is convenient for removing the residue inside the box. It is directly improved on the existing garbage truck and has a unique structure. Please refer to Figure 1-8 As shown, it includes a garbage truck 1, and also includes a lifting mechanism 2 and an automatic reel 3 arranged on the top of the box body of the garbage truck 1. A water pipe is wound on the automatic reel 3, and the output end of the lifting mechanism 2 extends downward into the box body of the garbage truck 1 and is fixedly installed with a cleaning mechanism 4. The automatic reel 3 is an existing device, and its working principle is to automatically reel the water pipe through an internal clockwork spring. The specific structure is not described in detail.

[0022] The cleaning mechanism 4 includes a shell 41 connected to the water pipe, a speed limiting component, a sliding rod 42 and a reciprocating screw 43 fixedly installed on the output end of the lifting mechanism 2 along the longitudinal interval, and a rotating shaft 45 rotatably installed at the front and rear ends of the shell 41 and hollow inside. The sliding rod 42 and the reciprocating screw 43 are both slidably sleeved with a slide cylinder 44, and the two slide cylinders 44 are fixedly connected to the shell 41; the two rotating shafts 45 are rotatably installed on the shell 41 through bearings. There are various ways to install the sliding rod 42 and the reciprocating screw 43. For example: the lifting mechanism 2 includes a multi-stage electric telescopic rod fixedly installed at the front and rear ends of the garbage truck 1 box body, and the output ends of the two multi-stage electric telescopic rods are fixedly installed with a fixed plate 5, and the two ends of the sliding rod 42 and the reciprocating screw 43 are respectively fixedly connected to the two fixed plates 5.

[0023] The ends of the two rotating shafts 45 away from each other are concentrically fixed with nozzles 46, and a plurality of first water spray outlets 47 are evenly arranged along the circumference of the two nozzles 46, and the plurality of first water spray outlets 47 are arranged offset from the axis of the nozzle 46. The sides of the two nozzles 46 away from each other are provided with a plurality of inclined second water spray outlets 48 along the circumference, and the plurality of second water spray outlets 48 correspond one-to-one to the plurality of first water spray outlets 47 and are connected to each other; the reciprocating screw 43 is threadedly sleeved with two reciprocating nuts 49 adapted thereto, and the outside of the two reciprocating nuts 49 are rotatably sleeved with fixing rings 410, and the two fixing rings 410 are fixedly connected to the shell 41, and the two rotating shafts 45 are respectively transmission-connected to the speed limiting assembly and the reciprocating nuts 49 on the adjacent side.

[0024] The speed limiting assembly includes a transmission belt 421, two transmission shafts 414 rotatably mounted in the housing 41, and an installation box 417 fixedly mounted at the bottom of the housing 41. The adjacent ends of the two rotating shafts 45 are fixedly sleeved with large bevel gears 413, and the two transmission shafts 414 are fixedly sleeved with small bevel gears 415. The two small bevel gears 415 are arranged opposite to each other, and the two small bevel gears 415 are respectively engaged with the two large bevel gears 413 for transmission; a copper ring 418 is fixedly sleeved on the inner wall of the installation box 417, and the two transmission shafts 414 are connected by the transmission belt 421, and the lower end of one of the transmission shafts 414 extends into the copper ring 418 and is fixedly sleeved with a rotating frame 419, and the rotating frame 41 A magnetic ring 420 is fixedly mounted on the outer ring surface of 9; there are various ways to install the transmission belt 421, for example: ring grooves are provided on the two transmission shafts 414, and the two ends of the transmission belt 421 are respectively mounted in the two ring grooves to prevent the transmission belt 421 from moving up and down. There are various ways to connect the rotating shaft 45 and the reciprocating nut 49, for example: the cleaning mechanism 4 also includes a transmission assembly arranged on the rotating shaft 45, and the two rotating shafts 45 are connected to the reciprocating nuts 49 on the adjacent sides through the transmission assembly. The transmission assembly includes a transmission belt 412, and also includes a pulley 411 fixedly mounted on the rotating shaft 45 and the reciprocating nut 49, and the two pulleys 411 are connected through the transmission belt 412.

[0025] Working principle: When the staff uses the device to clean the residue inside the garbage truck 1, they first connect the input end of the water pipe on the automatic reel 3 to the high-pressure water pump, and then start the lifting mechanism 2. The cleaning mechanism 4 is moved to the middle position of the garbage truck 1 through the lifting mechanism 2. The high-pressure water flows into the shell 41 through the water pipe, and the high-pressure water flows through the rotating shaft 45 and is sprayed out from the first water spray port 47 and the second water spray port 48 on the two nozzles 46. Since the multiple first water spray ports 47 are all set away from the axis of the nozzle 46, when the high-pressure water flow is sprayed out from the first water spray port 47, the nozzle 46 will generate an eccentric force, thereby driving the two nozzles 46 to rotate in the same direction. After the two nozzles 46 rotate, the two reciprocating nuts 49 are driven to rotate in the same direction through the belt drive, thereby driving the cleaning mechanism 4 to move back and forth horizontally in the garbage truck 1, thereby achieving the purpose of automatically cleaning the residue in the garbage truck 1, greatly reducing the labor intensity of the staff.

[0026] When the cleaning mechanism 4 moves back and forth, the automatic reel 3 can automatically reel in and release the water pipe, thereby preventing the water pipe from being entangled. In addition, when the nozzle 46 rotates, the large bevel gear 413 will be driven to rotate through the rotating shaft 45, and then the two transmission shafts 414 will be driven to rotate in the same direction through the meshing transmission with the small bevel gear 415. After the transmission shaft 414 rotates, it can drive the magnetic ring 420 to rotate, so that the copper ring 418 and the magnetic ring 420 rotate relative to each other. When the copper ring 418 and the magnetic ring 420 rotate relative to each other, the magnetic field generated by the induced current in the copper ring 418 will hinder this relative motion, thereby generating resistance, and indirectly hindering the rotation of the nozzle 46, reducing the rotation speed of the nozzle 46, extending the time for the nozzle 46 to flush a certain residue, and improving the cleaning effect.

[0027] Example 2: The difference between Example 2 and Example 1 is that Figure 4 As shown, the adjacent ends of the two rotating shafts 45 are sealed, and an annular cavity 416 is provided inside the housing 41, which is concentric with the rotating shaft 45. Sealing rings are provided on the rotating shaft 45 on both sides of the annular cavity 416. A water supply channel connecting the water inlet of the housing 41 and the annular cavity 416 is provided inside the housing 41, and a water inlet hole connected to the annular cavity 416 is provided on the circumference of the rotating shaft 45. By providing the water supply channel and the annular cavity 416 on the housing 41, high-pressure water flow can be delivered to the nozzle 46 through the water supply channel and the annular cavity 416, thereby preventing the high-pressure water flow from corroding and impacting the large bevel gear 413, the transmission shaft 414 and the small bevel gear 415, thereby extending their service life.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
