[0053] Reference Figure 1 and Figure 2 As shown, the present application is used for cleaning residual materials in the cargo compartment of the cleaning vehicle, comprising:

[0054] A cleaning device 100 for cleaning a carriage;

[0055] A vehicle body 200, on which a placement platform 210 for placing the cleaning device 100 is disposed, and the vehicle body 200 is laterally provided with an arm guide rail 220;

[0056] The arm assembly 300 includes a telescopic arm 310 and a rotating arm 320. The telescopic arm 310 is vertically arranged, and the lower end of the telescopic arm 310 is walkably connected to the arm guide rail 220. The rotating arm 310 is horizontally arranged and horizontally rotatably connected to the upper end of the telescopic arm 310. The cleaning device 100 is suspended below the rotating arm 320.

[0057] The residual material collecting device 400 includes a suction fan 410, a material conveying pipe 420, a suction nozzle 430 and a residual material collecting bin 440. The residual material collecting bin 440 is arranged on the vehicle body 200, and the suction nozzle 430 is arranged at the bottom of the cleaning device 100. One end of the material conveying pipe 420 is connected to the suction nozzle 430, and the other end is connected to the residual material collecting bin 440. The suction fan 410 is connected to the residual material collecting bin 440 so that the residual material collecting bin 440 generates negative pressure to absorb the residual material.

[0058] Reference Figure 1 As shown, during normal driving, the cleaning device 100 is parked on the placement platform 210 and will not affect the normal driving of the vehicle.

[0059] like Figure 2 and Figure 3 As shown, when the cleaning device 100 reaches the side of the carriage to be cleaned, the telescopic arm 310 extends upward, and then the rotating arm 320 rotates outward, and then the telescopic arm 310 moves toward the carriage on the side along the arm frame guide rail 220, and finally the cleaning device 100 is lifted above the carriage to be cleaned. Then the telescopic arm 310 is slowly lowered, and the cleaning device 100 is placed into the carriage from the top of the carriage to be cleaned, and the carriage starts to be cleaned.

[0060] While the cleaning device 100 is cleaning, under the action of the suction fan 410, negative pressure is generated in the residual material collection bin 440, and the cleaned residual materials are sucked into the residual material collection bin 440 through the conveying pipe 420 and the suction nozzle 430. After the cleaning of the carriage is completed, or the residual material collection bin 440 is full, the arm assembly 300 is recovered and the cleaning device 100 is recovered to the placement platform 210. Then the vehicle body 200 carries the residual material collection bin 440 filled with residual materials to the designated recycling location for processing.

[0061] like Figure 4 As shown, in some embodiments of the present invention, the residual material collection bin 440 includes a sedimentation chamber 441 and a filter chamber 442, the material conveying pipe 420 is connected to the sedimentation chamber 441, a baffle wall is provided between the sedimentation chamber 441 and the filter chamber 442, an air duct 443 connecting the sedimentation chamber 441 and the filter chamber 442 is provided on the baffle wall, the filter chamber 442 is connected to the suction fan 410, and a filter 450 is provided between the filter chamber 442 and the suction fan 410.

[0062] The swept material enters the settling chamber 441 along the conveying pipe 420 under the action of negative pressure. In the settling chamber 441, the ventilation cross-sectional area of ​​the settling chamber 441 becomes larger and the wind speed decreases. The heavier material settles in the settling chamber 441 under the action of gravity. Some small particles of material enter the filter chamber 442 from the air duct 443 on the retaining wall. Finally, only the air containing a small amount of material dust is filtered through the filter 450. The dust filtered by the air filter element remains in the filter chamber 442, and the clean air is discharged by the fan.

[0063] like Figure 4 As shown, the sedimentation chamber 441 and the filter chamber 442 are arranged sequentially from the rear end to the front end of the vehicle body 200, a sealing door 4411 is provided at the rear end of the sedimentation chamber 441, the rear end bottom of the residual material collecting bin 440 is hinged to the vehicle body 200, and a driving device 460 is provided between the bottom of the residual material collecting bin 440 and the vehicle body 200 to drive the residual material collecting bin 440 to rotate backward around the hinged portion to dump the material.

[0064] In addition, the sedimentation chamber 441 and the filtration chamber 442 may also be arranged side by side in a transverse manner, and a sealing door 4411 is provided on the side of the sedimentation chamber 441 to dump the collected residual materials from the side of the sedimentation chamber 441 from the side.

[0065] like Figure 5 As shown, after the sweeper reaches the waste material processing location, the sealed door 4411 is opened, and the driving device 460 drives the waste material collection bin 440 to flip backward around the hinged portion to pour out the waste material in the settling chamber 441. The material in the filter chamber 442 will also enter the settling chamber 441 along the air duct 443 and be poured out.

[0066] like Figure 4 As shown, the retaining wall includes a movable plate 471 and a fixed plate 472 which are staggered and spaced apart in the direction of the sedimentation chamber 441 and the filtration chamber 442; the lower end of the movable plate 471 is movably connected to the bottom of the residual material collecting bin 440; the upper end of the movable plate 471 is spaced apart from the top of the residual material collecting bin 440; the movable plate 471 can rotate around the bottom of the movable plate 471 toward the sealing door 4411; the upper end of the fixed plate 472 is fixedly connected to the top of the residual material collecting bin 440; and the lower end of the fixed plate 472 is spaced apart from the bottom of the residual material collecting bin 440.

[0067] The movable plate 471 and the fixed plate 472 together form a zigzag air duct 443 to increase the sedimentation of the residual material. At the same time, when dumping the material, the movable plate 471 will tilt and rotate toward the sealing door 4411 to a certain extent, so that the residual material deposited in the filter chamber 442 and between the movable plates 471 can enter the sedimentation chamber 441. It should be noted that most of the residual material in the filter chamber 442 and between the movable plates 471 are small particles of dust. The movable plate 471 only needs to be able to deflect a certain angle, and the dust can be easily poured into the sedimentation chamber 441.

[0068] Reference Figures 6 to 9 As shown, the cleaning device 100 includes:

[0069] A lifting mechanism 1100, the lifting mechanism 1100 is connected to the rotating arm 320 via a first pull rope 500;

[0070] A mounting frame 1300, the mounting frame 1300 is connected to the upper lifting mechanism 1100 through a first lifting mechanism;

[0071] At least two side wall cleaning mechanisms 1600, the side wall cleaning mechanisms are respectively arranged on the left and right sides of the mounting frame 1300, the side wall cleaning mechanisms 1600 include a vertical brush 1610, a vertical brush frame 1620 and a vertical brush driving device 1630, the vertical brush 1610 is vertically rotatably connected to the outer side of the vertical brush frame 1620, the vertical brush driving device 1630 is transmission-connected to the vertical brush 1610 to drive the vertical brush 1610 to rotate, and the vertical brush frame 1620 is vertically rotatably connected to the side of the mounting frame 1300;

[0072] A synchronous retracting mechanism 1800, which is connected between the two brush holders 1620. As the mounting frame 1300 and the lifting mechanism 1100 move away from each other, the synchronous retracting mechanism 1800 drives the two brush holders 1620 to rotate inwards;

[0073] The return device 1700 is connected to the vertical brush frame 1620 to pull the vertical brush frame 1620 to rotate outward.

[0074] like Figure 6 As shown, when the carriage needs to be cleaned, the rotating arm 320 lifts the lifting mechanism 1100 through the first pull rope 500. Under the action of its own gravity, the first lifting mechanism between the mounting frame 1300 and the lifting mechanism 1100 is stretched, and the height of the entire cleaning device reaches the maximum. As the distance between the mounting frame 1300 and the lifting mechanism 1100 increases, the synchronous retraction mechanism 1800 drives the two vertical brush racks 1620 to rotate inward and retract, and the distance between the two vertical brush racks 1620 is gradually reduced to the minimum, obtaining a smaller insertion width, so that the cleaning device can be placed in carriages of different widths;

[0075] like Figure 7 As shown, after the cleaning device is placed in the carriage, the mounting frame 1300 first contacts the bottom of the carriage, and at this time the cleaning device continues to be lowered, the first lifting mechanism begins to shorten, and the distance between the mounting frame 1300 and the lifting mechanism 1100 decreases, and then the synchronous retracting mechanism 1800 begins to remove the force on the two vertical brush frames 1620. Subsequently, the two vertical brush frames 1620 are pulled outward by the return device 1700, and the distance between the two vertical brush frames 1620 gradually increases and opens until the vertical brush 1610 contacts the side wall of the carriage, thereby achieving the purpose of the cleaning device adapting to the width of the carriage.

[0076] At this time, the two vertical brushes 1610 are in contact with the side walls of the carriage and can start to clean the side walls of the carriage. Driven by related equipment, the cleaning device moves back and forth in the carriage to clean the carriage.

[0077] In the present application, the cleaning device can automatically adapt to the width of different carriages by relying on its own gravity to meet the cleaning needs of different carriages. It does not require additional power to adapt to the width of the carriage, and can complete the cleaning of the bottom of the vehicle and the walls of the carriage at the same time.

[0078] like Figures 6 to 8 As shown, a carriage positioning mechanism 1200 is provided between the lifting mechanism 1100 and the mounting frame 1300, and the carriage positioning mechanism 1200 includes a positioning mechanism frame 1210, a left positioning device 1220, a right positioning device 1230 and a telescopic connecting rod mechanism 1240;

[0079] The positioning mechanism frame 1210 and the lifting mechanism 1100 are connected via a telescopic guide shaft 1120, which is composed of a lifting mechanism guide sleeve connected to the lifting mechanism 1100 and a positioning frame guide sleeve connected to the positioning mechanism frame 1210, so that the telescopic guide shaft 1120 can be telescoped up and down;

[0080] The positioning mechanism frame 1210 and the mounting frame 1300 are connected via a second lifting mechanism 1400, and the second lifting mechanism 1400 is composed of a lifting rod connected to the mounting frame 1300 and a positioning frame guide sleeve;

[0081] The left positioning device 1220 and the right positioning device 1230 each include a positioning wheel mounting plate 1221, a top positioning wheel 1222 and a side wall positioning wheel 1223. The left positioning device 1220 and the right positioning device 1230 are symmetrically arranged. The middle parts of the two positioning wheel mounting plates 1221 are rotationally connected to the left and right sides of the positioning mechanism frame 1210 through a rotating shaft 1250. The top positioning wheel 1222 and the side wall positioning wheel 1223 are both rollingly connected to the positioning wheel mounting plate 1221. The rolling surfaces of the top positioning wheel 1222 and the side wall positioning wheel 1223 correspond to the top and side wall of the carriage, respectively.

[0082] The telescopic link mechanism 1240 is connected to the positioning mechanism frame 1210 , and the telescopic link mechanism 1240 is connected to the two positioning wheel mounting plates 1221 to drive the positioning wheel mounting plates 1221 to rotate around the rotating shaft 1250 . A second pull rope 1260 is provided between the telescopic link mechanism 1240 and the lifting mechanism 1100 .

[0083] When the cleaning device is lifted, the guide shaft 1120 between the positioning mechanism frame 1210 and the lifting mechanism 1100 is extended, the positioning mechanism frame 1210 moves downward, and the second pull rope 1260 provided between the telescopic link mechanism 1240 and the lifting mechanism 1100 begins to be subjected to force, opening the telescopic link mechanism 1240 to a certain angle. This angle facilitates the top positioning wheel 1222 and the side wall positioning wheel 1223 to fall onto the top and side wall of the car wall.

[0084] When the cleaning device is placed in the carriage, as the height of the entire cleaning device decreases, the top positioning wheel 1222 will first contact the top of the carriage. After the top positioning wheel 1222 contacts the top of the carriage, the distance between the positioning mechanism frame 1210 and the lifting mechanism 1100 gradually decreases, and the second pull rope 1260 loses its tension and becomes loose. Under the support force of the side wall of the carriage, the top positioning wheel 1222 pushes the positioning wheel mounting plate 1221 to rotate around the rotating shaft 1250, and finally makes the wall positioning wheel 1223 contact and press against the side wall of the carriage. At the same time, the top positioning wheel 1222 and the side wall positioning wheel 1223 symmetrically arranged on the other side of the carriage also contact the other side wall of the carriage at the same time, and make the center of the cleaning device 100 coincide with the center of the carriage. The cleaning device 100 can be provided with multiple sets of carriage positioning wheels to improve stability.

[0085] Finally, during cleaning, the rotating arm does not need the rotating arm 320 to bear the gravity of the cleaning device 100, and the gravity of the cleaning device 100 acts completely on the carriage. Under the action of gravity, the carriage positioning mechanism 1200 can enable the cleaning device 100 to be attached to the carriage, and the top positioning wheel 1222 and the side wall positioning wheel 1223 of the positioning mechanism can move back and forth with the two side walls of the carriage as guide rails, and can keep the center of the cleaning device 100 completely coincident with the center of the carriage during movement.

[0086] During cleaning, the cleaning device 100 can be dragged by the vehicle body to move back and forth along the length direction of the carriage, or the cleaning device 100 can be driven by its own power to move back and forth along the carriage for cleaning.

[0087] In some embodiments of the present invention, a vehicle bottom cleaning mechanism 1500 is provided at the bottom of the mounting frame 1300. The vehicle bottom cleaning mechanism 1500 includes a horizontal brush and a horizontal brush driving motor for driving the horizontal brush to rotate. The horizontal brush is horizontally arranged at the bottom of the mounting frame 1300. When the horizontal brush contacts the bottom of the vehicle compartment, the bottom of the vehicle can be cleaned while walking in the vehicle compartment.

[0088] In some embodiments of the present invention, Fig.12 As shown, the horizontal brush includes a horizontal brush shaft 1510 and a vehicle bottom material loosening and cleaning structure arranged on the horizontal brush shaft 1510, and the horizontal brush driving device is transmission-connected to the horizontal brush shaft 1510 to drive the horizontal brush shaft 1510 to rotate.

[0089] The horizontal brush shaft 1510 rotates under the drive of the horizontal brush driving device, and the material loosening and cleaning structure at the bottom of the vehicle loosens the material attached to the bottom of the vehicle. After the material at the bottom of the vehicle is loosened, the suction nozzle 430 can suck it away.

[0090] In this embodiment, the underbody material loosening and cleaning structure includes a transverse brush 1520 and a transverse steel wire 1530, which are alternately distributed on the transverse brush shaft 1510. The transverse brush 1520 and the transverse steel wire 1530 are spirally arranged from both ends of the transverse brush shaft 1510 to the middle, forming a V-shaped structure.

[0091] Similarly, the horizontal steel wire 1530 loosens the hardened material, destroys the hardened material structure and crushes the large pieces of residual material, so that the adhered material is separated from the bottom of the vehicle. The horizontal brush 1520 sweeps the separated residual material particles and dust to the middle of the cleaning device.

[0092] The horizontal brush 1520 and the horizontal steel wire 1530 are arranged in a spiral from both ends of the horizontal brush shaft 1510 to the middle, forming a V-shaped structure. This arrangement allows the horizontal brush 1500 to sweep the materials at both ends of the horizontal brush 1500 toward the center of the horizontal brush 1500 when rotating, so that the swept materials are closer to the suction nozzle 430 located in the middle of the cleaning device, and are easier to be sucked away. Furthermore, a set of scrapers 1540 are provided on opposite sides of the horizontal brush shaft 1510. The scrapers 1540 are arranged in parallel with the horizontal brush 1520 and the horizontal steel wire 1530, and are arranged in a spiral from both ends of the horizontal brush shaft 1510 to the middle, forming a V-shaped structure.

[0093] Compared with the horizontal brush 1520 and the horizontal wire 1530, the scraper 1540 can better sweep and collect the residual materials toward the center of the horizontal brush. At the same time, during cleaning, a relatively closed area is formed between the scraper 1540 and the bottom of the vehicle, so that the negative pressure near the suction nozzle 430 is greater and the suction force is stronger.

[0094] When the cleaning device moves to one end of the car, the telescopic arm 310 moves upward to lift the cleaning device 100. At this time, the vertical brushes 1610 on both sides cannot clean the side walls at the end of the car. At this time, the cleaning device needs to be repeatedly lifted and lowered by the lifting device, and the side walls at the end of the car need to be cleaned by the horizontal brush.

[0095] In some embodiments of the present invention, the mounting frame 1300 includes a telescopic frame 1310 and a structural frame 1320 arranged up and down, the telescopic frame 1310 is connected to the positioning mechanism frame 1210 through the second lifting mechanism 1400, and the structural frame 1320 is connected to the bottom of the telescopic frame 1310 through the rotating mechanism 1330.

[0096] In this embodiment, the second lifting mechanism 1400 is connected by a lifting rod and a guide shaft sleeve, and the two can slide up and down and extend and retract to achieve the purpose of lifting.

[0097] Due to the structural design of the present application, only one side of the horizontal brush can clean the end surface of the carriage (reference Fig. 9 When the two vertical brushes retract, there will be a groove surface between the two vertical brushes, which will interfere with the cleaning of the horizontal brush. Only the back surface can be cleaned. Therefore, when it is necessary to clean the other end surface, the entire cleaning device needs to be lifted up and then turned as a whole.

[0098] In order to solve this problem, this embodiment connects the telescopic frame 1310 and the structural frame 1320 through a rotating mechanism 1330. After cleaning one end surface, it is only necessary to rotate the rotating mechanism to drive the structural frame 1320 to rotate 180° to clean the other end surface. This eliminates the need to turn the entire cleaning device, thereby improving the cleaning efficiency.

[0099] In some embodiments of the present invention, the synchronous retraction mechanism 1800 includes a third pull rope 1810, a transmission member 1820 and two connecting rods 1830. The transmission member can be rotatably connected to the structural frame 1320. The two sides of the transmission member are respectively connected to the vertical brush frame 1620 through the connecting rods 1830. One end of the third pull rope 1810 is connected to the transmission member, and the other end is connected to the positioning mechanism frame 1210. The two connecting rods 1830 retract inward as the transmission member rotates.

[0100] The synchronous retraction mechanism 1800 includes that when it is lifted, as the mounting frame 1300 moves downward, the distance between the mounting frame 1300 and the positioning mechanism frame 1210 gradually increases, and the third pull rope 1810 will pull the transmission member to rotate. As the transmission member rotates, the connecting rods 1830 on both sides retract inward, pulling the vertical brush frame 1620 to rotate inward, thereby shortening the distance between the two vertical brush frames 1620 to facilitate placement in the car.

[0101] In some embodiments of the present invention, the transmission member 1820 is a triangle, the middle part of the base of the triangle can be rotatably connected to the structural frame 1320, the two ends of the base of the triangle are respectively connected to the vertical brush frame 1620 through the connecting rod 1830, one end of the third pull rope 1810 is connected to the triangle, and the other end is connected to the positioning mechanism frame 1210.

[0102] In this embodiment, a triangle is preferably used as the transmission member 1820, but other shapes, such as a circle, may also be used as long as the two connecting rods 1830 can be retracted inwardly as the triangle rotates.

[0103] The return device 1700 is an elastic member, such as a spring, a rubber strip, etc., and is preferably a return spring in the present application. One end of the elastic member is connected to the vertical brush holder 1620, and the other end is connected to the structural frame 1320 to pull the vertical brush holder 1620 to rotate outward.

[0104] After the cleaning device is placed in the carriage, as the mounting frame 1300 and the positioning mechanism frame 1210 gradually decrease, the triangle will lose the pulling force of the third pull rope 1810. At this time, the vertical brush frame 1620 will rotate outward under the action of the return spring until the vertical brush 1610 on the vertical brush frame 1620 contacts the side wall of the carriage, so that the cleaning device can clean the two side walls.

[0105] like Fig.10 What is shown is a schematic diagram of the structure of an embodiment of the second cleaning part, the synchronous retraction mechanism includes two synchronous sprockets 2100, a guide rail 2200 and a vertical brush retraction drive device 2300, the guide rail 2200 is transversely arranged on the structural frame 1320, the two synchronous sprockets 2100 are symmetrically arranged on the left and right sides of the structural frame 1320, the two synchronous sprockets 2100 are connected by a synchronous chain 2400, the two vertical brush frames 1620 are symmetrically arranged and slidably connected to the guide rail 2200, the two vertical brush frames 1620 are respectively connected in series on the upper and lower sides of the synchronous chain 2400 by connecting pins 2500, and the vertical brush retraction drive device 2300 is transmission-connected to one of the vertical brush frames 1620 to drive the vertical brush frame 1620 to slide along the guide rail 220.

[0106] In the first synchronous retraction mechanism, when the vertical brushes 1610 on both sides are retracted, the third pull rope 1810 pulls the transmission member 1820 to rotate to realize the vertical brush assembly to be retracted inwards, and is pulled outwards by the spring, and the vertical brush is retracted by gravity and spring force. The mechanism is relatively simple and does not require additional power, but it can only achieve a certain range of opening and closing, and cannot retract the vertical brushes on both sides to the middle of the cleaning device.

[0107] In this embodiment, a slider 2600 and a connecting pin 2500 are installed on the vertical brush frame 1620, and a synchronous sprocket 2100, an annular synchronous chain 2400 and a guide rail 2200 are installed on the structural frame 1620. The vertical brush frame 1620 equipped with the slider 2600 can move back and forth along the guide rail 2200. Since the connecting pin 2500 on the vertical brush frame 1620 is connected in series to the symmetrical position of the upper and lower sides of the annular synchronous chain 2400, when one vertical brush frame 1620 moves, the vertical brush frame 1620 on the other side will also move synchronously in a mirror image.

[0108] One end of the vertical brush retraction drive mechanism 2300 (which can be an oil cylinder, a pneumatic cylinder, or an electric cylinder) is installed on the structural frame 1320, and the other end is installed on a vertical brush holder 1620. When the vertical brush retraction drive mechanism 2300 pushes the vertical brush holder 1620 on one side to move outward and open, the vertical brush holder 1620 on the other side also opens outward synchronously. When the vertical brush retraction drive mechanism 2300 extends a certain distance so that the vertical brushes 1610 on both sides are in contact with the side wall of the car at the same time, the cleaning operation can begin.

[0109] When cleaning to the end of the carriage, slowly retract the vertical brush retraction drive mechanism 2300, and the vertical brushes 1610 on both sides move synchronously toward the middle to clean the wall at the end of the carriage, while the bottom disc brush sweeps the material under the car to the suction nozzle in the middle.

[0110] Fig.11 This is a simplified schematic diagram of the use structure of the lifting mechanism of the cleaning device. In this embodiment, the positioning mechanism frame 1210 is simplified. The rotating arm 320 directly lifts the two telescopic guide shafts 1120 through the fourth pull rope 2700. The telescopic guide shafts 1120 move back and forth on the frame of the carriage positioning mechanism 1200 to achieve the first-level telescopic movement of the cleaning device. The fifth pull rope 2800 directly connects the rotating arm 320 and the carriage positioning mechanism 1200.

[0111] Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
