It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0019] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "inner," and "outer" in the terminology represent the orientation of the term in its normal use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0020] like Figure 1-7As shown, a municipal engineering trench garbage cleaning device includes a cleaning vehicle body and a lifting device installed on the outside of the cleaning vehicle body. The garbage cleaning device also includes a crossbeam 1 fixedly connected to the output end of the lifting device, a garbage gathering device fixedly connected to the end of the crossbeam 1 away from the lifting device via a mounting frame 2 and located below the crossbeam 1, and a collection and filtration device for filtering water fixedly connected to the garbage gathering device. The garbage collection device includes a garbage collection box 3 with an open top and one side facing the forward direction of the main body of the cleaning vehicle. The side wall of the garbage collection box 3 opposite to the side wall opening is formed with a channel 4 for garbage to pass through. The garbage collection box 3 includes a pair of side plates 5 that can rotate to adjust the range of the side wall opening. The collection and filtration device includes a mesh garbage bag 6 for filtering water, a mouth opener 7 for opening the mesh garbage bag 6 and adapting to the channel 4, and a support frame 8 fixedly connected to the garbage collection box 3 for supporting the mesh garbage bag 6. The mouth opener 7 is detachably installed on the outer wall of the garbage collection box 3.

[0021] The main body of the cleaning vehicle and the lifting device are both existing technologies and are not shown in the figure. The Chinese invention patent with publication number CN114056813A, "An auxiliary dumping device for a hook-lift garbage truck", discloses a hook-lift garbage truck and a lifting assembly. The main body of the cleaning vehicle and the lifting device can be a hook-lift garbage truck and a lifting assembly.

[0022] When it is necessary to clean up the garbage in the ditch, the main body of the cleaning vehicle is driven to the edge of the ditch. The lifting device drives the crossbeam 1 to move vertically downwards. The mounting frame 2 drives the garbage gathering device to move into the ditch, so that the upper part of the garbage gathering device is above the water surface. The main body of the cleaning vehicle moves, driving the garbage gathering device to move on the water surface. The side plate 5 can expand the feed port range of the garbage gathering box 3. Because the garbage gathering box 3 is moving, and the floating garbage floats very slowly, the speed difference can be used to load the garbage into the garbage gathering box 3. After entering the garbage gathering box 3, the garbage enters the mesh garbage bag 6 through the channel 4. The water can be filtered out through the mesh garbage bag 6, and the garbage is loaded into the mesh garbage bag 6. The water level does not exceed the channel 4.

[0023] When the mesh garbage bag 6 is full and needs to be replaced, the lifting device moves the garbage gathering device upward through the mounting frame 2 and moves it out of the trench. The main body of the cleaning vehicle moves the garbage gathering device away from directly above the trench. Because the garbage in the mesh garbage bag 6 contains a lot of water, the support frame 8 is needed to support the mesh garbage bag 6 to prevent the mesh garbage bag 6 from breaking due to excessive weight. Remove the mouth support 7 from the garbage gathering box 3 and then remove the mouth support 7 from the mesh garbage bag 6. Take out a new mesh garbage bag 6 and install the mouth support 7 on the open end of the mesh garbage bag 6 to open it up, so that the garbage can enter the mesh garbage bag 6. Place the mesh garbage bag 6 in the support frame 8, install the mouth support 7 on the garbage gathering box 3, and throw the full mesh garbage bag 6 into the main body of the cleaning vehicle.

[0024] The waste collection device also includes a horizontal connecting shaft 9 located inside the waste collection box 3 and axially connected to the side wall of the waste collection box 3, several paddle wheels 10 spaced and sleeved on the connecting shaft 9, and a waterproof motor 11 fixedly installed on the outer wall of the waste collection box 3, with its output shaft passing through the side wall of the waste collection box 3 and coaxially fixedly connected to the connecting shaft 9 via a coupling. Several paddle blades 12 are fixedly installed on each paddle wheel 10. The length direction of the connecting shaft 9 is perpendicular to the forward direction of the main body of the cleaning vehicle, and the height of the connecting shaft 9 is lower than the height of the top of the through groove 4.

[0025] When the garbage collection bin 3 moves on the water surface, although the water can pass through the channel 4 and the mesh garbage bag 6, the water flow will still be resisted, causing some garbage to not be able to enter the garbage collection bin 3 smoothly. Therefore, the motor 11 drives the connecting shaft to rotate, and the connecting shaft 9 drives the paddle 12 to rotate, causing the water to flow towards the mesh garbage bag 6, so that the floating garbage follows the water flow through the channel 4 and enters the mesh garbage bag 6.

[0026] Each pair of side plates 5 is rotatably connected to both sides of the open side wall of the garbage collection bin 3 via a vertical pivot 13. The bottom of the garbage collection bin 3 is fixedly provided with a horizontal bottom plate 14 extending along the open side wall. Each side plate 5 is slidably or fixedly connected to the bottom plate 14 via a connecting mechanism 15.

[0027] When it is necessary to adjust the range of the feed inlet of the garbage collection bin 3 through the side plate 5, the connecting mechanism 15 is opened so that the side plate 5 can rotate around the rotating shaft 13, and then the side plate 5 and the bottom plate 14 are fixed together through the connecting mechanism 15 to adapt to grooves of different widths.

[0028] The connecting mechanism 15 includes an arc-shaped plate 16 that fits against the lower surface of the base plate 14 and is fixedly connected to the bottom end of the side plate 5, a vertical connecting bolt 17 that slides through the base plate 14 and is threadedly connected to the arc-shaped plate 16, and a positioning member 18 that is sleeved on the connecting bolt 17 and engaged with the upper surface of the base plate 14. The base plate 14 is formed with an arc-shaped through groove 19 that is coaxial with the rotating shaft 13 and allows the connecting bolt 17 to pass through. The base plate 14 is recessed with a plurality of positioning grooves 20 that are equally spaced along the arc direction of the arc-shaped through groove 19 and are adapted to the positioning member 18.

[0029] When it is necessary to rotate the side plate 5, loosen the connecting bolt 17 so that the positioning piece 18 can move upward and be pulled out from the positioning groove 20. At this time, the connecting bolt 17 can slide in the arc-shaped through groove 19. Rotate the side plate 5, and the side plate 5 drives the connecting bolt 17 to slide in the arc-shaped through groove 19 through the arc plate 16. When the position of the side plate 5 is adjusted, insert the positioning piece 18 downward into the corresponding positioning groove 20, tighten the connecting bolt 17 to fix the positioning piece 18 in the positioning groove 20, and fix the arc plate 16 and the side plate 5.

[0030] The top of the support frame 8 and the side near the through slot 4 are open. The bottom of the support frame 8 is fixedly connected to the bottom of the garbage collection box 3. Both sides of the open side wall of the support frame 8 are fixedly connected to the outer wall of the garbage collection box 3 through connectors 21. The connectors 21 are formed with vertical positioning slots for the mouth support 7 to slide into. The top of the side wall of the support frame 8 opposite to the open side wall is rotatably connected to a connecting arm 23 located above the mesh garbage bag 6 through a hinge support 22. The end of the connecting arm 23 away from the hinge support 22 is fixed or separated from the garbage collection box 3 by several bolts 24. A limiting member 25 that can abut against the top of the mouth support 7 to fix the mouth support 7 in the positioning slot is fixedly connected to the connecting arm 23.

[0031] When the mouth opener 7 needs to be installed, open the connector 21 to separate the connecting arm 23 from the garbage collection box 3. Rotate the connecting arm 23 around the hinge support 22 away from the mouth opener 7, causing the limiting member 25 to separate from the mouth opener 7. Pull the mouth opener 7 vertically upward from the positioning slot and remove the mouth opener 7 and the mesh garbage bag 6 filled with garbage from the support frame 8. When the spreader needs to be installed, insert the two sides of the mouth opener 7 downward into the positioning slots respectively. Rotate the connecting arm 23 so that the limiting member 25 abuts against the upper surface of the mouth opener 7, fix the mouth opener 7 in the positioning slot, and fix the connecting arm 23 and the garbage collection box 3 together through the connector 21.

[0032] The connecting arm 23 can not only be used to install the mouth support 7, but also to provide an upward pulling force to the side of the support frame 8 away from the mouth support 7, so as to prevent the water-containing garbage in the mesh garbage bag 6 from being too heavy and pressing the side of the support frame 8 away from the mouth support 7 downward and deforming it.

[0033] The mouth support 7 includes a rectangular inner frame 29 and a rectangular outer frame 26 that can be separably fitted onto the rectangular inner frame 29. The two sides of the rectangular outer frame 26 can be slidably inserted into the corresponding positioning slots. The bottom of the garbage collection bin 3 is fixedly extended with a support part 27 that fits against the bottom of the rectangular outer frame 26 on the side near the through groove 4.

[0034] When the mouth support 7 needs to be removed from the mesh garbage bag 6, remove the rectangular outer frame 26 from the rectangular inner frame 29 and remove the open end of the mesh garbage bag 6 from between the rectangular outer frame 26 and the rectangular inner frame 29; when the mouth support 7 needs to be installed on the mesh garbage bag 6, place the open end of the mesh garbage bag 6 on the outside of the rectangular inner frame 29, and then place the rectangular outer frame 26 on the rectangular inner frame 29 to clamp the open end of the mesh garbage bag 6.

[0035] The bottom plate portion 14 has a downwardly sloping flared portion 28 formed on the side away from the through groove 4.

[0036] The flared section 28 facilitates the movement of floating garbage to the top of the bottom plate 14.

[0037] The bottom surface of the rectangular inner frame 29 has a first strip-shaped clip 30 protruding in the same length direction. The bottom surface of the rectangular outer frame 26 has a first strip-shaped slot 31 for inserting the first strip-shaped clip 30. The top edge of the rectangular outer frame 26 is a strip-shaped positioning plate 32 that can be detachably and snapped onto the top of the rectangular inner frame 29. The side of the strip-shaped positioning plate 32 near the garbage collection bin 3 is rotatably connected to the two sides of the rectangular outer frame 26 through a pivot 13.

[0038] When cleaning up garbage, the water flow and garbage will continuously impact the mesh garbage bag 6 and move it away from the garbage collection bin 3. There is a probability that the open end of the mesh garbage bag 6 will slip off the mouth support 7. Therefore, the first strip 30 is inserted into the first strip slot 31 to fix part of the open end of the mesh garbage bag 6. The strip positioning plate 32 can rotate so that the first strip 30 can be inserted into the first strip slot 31.

[0039] The top surface of the rectangular inner frame 29 has a second strip-shaped groove 33 recessed in the same length direction. The strip-shaped positioning plate 32 has a second strip-shaped locking strip 34 protruding from it, which can be inserted into the second strip-shaped groove 33. The top of both sides of the rectangular outer frame 26 has a screw-in part 35 protruding from it. Both ends of the second strip-shaped groove 33 have a strip-shaped mounting through groove 36 that is aligned with the length direction and the direction of the rotating shaft 13. Each screw-in part 35 is threaded with a mounting bolt 37 that can pass through the corresponding strip-shaped mounting through groove 36 to fix the strip-shaped positioning plate 32.

[0040] When it is necessary to separate the rectangular inner frame 29 from the rectangular outer frame 26, loosen and remove the mounting bolt 37, rotate the strip-shaped positioning plate 32 to move the second strip-shaped locking strip 34 out of the second strip-shaped locking groove 33, lift the rectangular inner frame 29 upwards to move the first strip-shaped locking strip 30 out of the first strip-shaped locking groove 31, and separate the rectangular inner frame 29 from the rectangular outer frame 26. When it is necessary to install the rectangular inner frame 29 and the rectangular outer frame 26, insert the first strip-shaped locking strip 30 into the first strip-shaped locking groove 31, and move the strip-shaped positioning plate 32 towards the rectangular inner frame 29. Insert the mounting bolt 37 into the strip-shaped mounting through groove 36 and screw it into the screw joint 35. Tighten the mounting bolt 37 so that the second strip-shaped locking strip 34 is engaged in the second strip-shaped locking groove 33. The second strip-shaped locking strip 34 engaging in the second strip-shaped locking groove 33 can also fix part of the opening end of the mesh garbage bag 6. The outer surfaces of the two sides of the rectangular inner frame 29 are both first inclined sidewalls 38, and the side closer to the garbage collection bin 3 is inclined to the inner side of the rectangular inner frame 29. The inner surfaces of the two sides of the rectangular outer frame 26 are second inclined sidewalls 39 that are adapted to the first inclined sidewalls 38 to fix the opening end of the mesh garbage bag 6.

[0041] The first inclined sidewall 38 and the second inclined sidewall 39 not only facilitate the rectangular outer frame 26 to be fitted outside the rectangular inner frame 29, but also can clamp the opening end of the mesh garbage bag 6. The first strip-shaped clip 30 and the first strip-shaped slot 31, the second strip-shaped clip 34 and the second strip-shaped slot 33, and the first inclined sidewall 38 and the second inclined sidewall 39 are adapted to fix the entire opening end of the mesh garbage bag 6.
