Description

Technical Field

[0001] The present invention relates to the technical field of pure electric sanitation vehicles, and specifically to a pure electric sanitation vehicle with a garbage dumping structure. Background Technique

[0002] With the improvement of environmental awareness and the development of electric vehicle technology, more and more cities have begun to use electric sanitation vehicles for garbage collection operations, especially in urban streets and within residential areas. As one of them, the bucket-hanging sanitation vehicle is mainly used for garbage collection from trash cans. Through mechanized operation, it effectively reduces the labor intensity of sanitation workers and improves the operation efficiency. Such vehicles are usually equipped with a garbage dumping structure (such as a bucket-hanging device), and the bucket-hanging device is connected to the cover plate of the garbage inlet through a linkage mechanism to achieve up-and-down flipping movement, thereby driving the bucket-hanging device to slide along the outer wall of the carriage, completing the garbage dumping process and simultaneously controlling the opening and closing of the garbage inlet.

[0003] However, in the design of traditional sanitation vehicles, the garbage inlet is generally fixedly arranged at the top of the carriage. This layout causes the garbage to accumulate at a specific position after entering the carriage from the garbage inlet and cannot be evenly distributed to other areas inside the carriage. In addition, due to the large gaps between the garbage falling naturally, it further affects the utilization rate of the effective volume of the carriage. This not only limits the amount of garbage transported each time, increases the number of garbage collection trips, but also indirectly increases the operating cost and the impact on the environment. In view of the above problems, the present invention proposes a pure electric sanitation vehicle with a garbage dumping structure. Summary of the Invention

[0020] Optionally, a front end plate capable of flipping vertically is provided at the front end of the garbage bin fixing member.

[0027] 3. The tensioning device of the present invention includes a connecting rope and a tension sensor. The tension sensor can monitor the tension of the winding motor on the tensioning rope in real time. According to the tension, the squeezing force of the pressing component on the garbage can be indirectly obtained.

This enables the simultaneous realization of opening the carriage cover, dumping garbage, leveling garbage, and compacting garbage. In this way, the efficiency of garbage treatment can be further improved. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] Embodiment: Please refer to Figures 1 to 12 , a pure electric sanitation vehicle with a garbage dumping structure is provided according to an embodiment of the present invention. The top of the carriage 10 of the pure electric sanitation vehicle has a garbage inlet 11, and a garbage pushing and leveling mechanism 20 is arranged in the carriage 10. The garbage pushing and leveling mechanism 20 includes a moving part 21, a pressing part 22 and a tensioning device 23. Among them, the moving part 21 is movably arranged on the top of the carriage 10 along a first horizontal direction. In Figure 7 , the first horizontal direction is the length direction of the carriage 10; the pressing part 22 is arranged opposite to the moving part 21 in the vertical direction and is movably connected to the moving part 21 through two pairs of connecting rods 24. In Figure 7 , the vertical direction is the height direction of the carriage 10, and the two connecting rods 24 of each pair of connecting rods 24 are rotatably connected through a rotating connector 25; the tensioning device 23 includes a winding motor 230 and a tensioning rope 231, and the winding motor 230 is fixedly installed on the moving part 21; the tensioning rope 231 is sleeved between the rotating connectors 25 of the two pairs of connecting rods 24 and is connected to the output shaft of the winding motor 230.

[0045] For the all-electric sanitation vehicle with a garbage dumping structure adopting the above structure, after the garbage falls into the interior of the carriage 10 from the garbage inlet 11, the garbage pushing and leveling mechanism 20 can push, level and compact the garbage falling into the carriage 10, evenly disperse the piled-up garbage in the carriage 10 to various areas of the carriage 10, and compress the volume of the garbage, thereby improving the garbage-holding capacity of the carriage 10. During specific operation, the moving part 21 of the garbage pushing and leveling mechanism 20 reciprocates along the first horizontal direction, and the pressing part 22 moves synchronously with the moving part 21, so that the garbage piled up in the carriage 10 can be pushed to various areas in the carriage 10. After that, by rotating the winding motor 230 to pull the tensioning rope 231, controlling the pressing part 22 to apply a downward pressure to the garbage, the compression treatment of the garbage can be realized. Moreover, the height of the pressing part 22 can be controlled within a certain range according to the height of the garbage piled up in the carriage 10 to ensure that the pressing part 22 applies a relatively balanced pressure to the garbage. In addition, since the moving part 21 and the pressing part 22 are connected by two pairs of connecting rods 24, as the height of the garbage piled up in the carriage 10 increases, the pressing part 22 gradually approaches the moving part 21, and the connecting rods 24 can be well folded between the moving part 21 and the pressing part 22, which can minimize the internal space of the carriage 10 occupied by the garbage pushing and leveling mechanism 20 and improve the loading capacity of the carriage 10.

[0046] As Figure 9 shown, on the basis of the above embodiment, the pressing part 22 includes a mounting frame 220 and a roller 221. There are push plates 222 at the front and rear of the mounting frame 220. The upper part of the mounting frame 220 is rotatably connected to the connecting rod 24 through a rotating shaft. The roller 221 protrudes from the bottom of the push plate 222. The roller 221 is arranged along the second horizontal direction perpendicular to the first horizontal direction and is rotatably connected to the lower part of the mounting frame 220. In FIG. 7, the second horizontal direction is the width direction of the carriage 10. With such a setting, when the pressing part 22 follows the moving part 21 to reciprocate along the first horizontal direction, the push plates 222 at the front and rear of the mounting frame 220 can push the garbage flat. At the same time, the roller 221 at the bottom of the mounting frame 220 can compact the flattened garbage. In this way, the pushing and compressing of the garbage can be carried out synchronously, thereby improving the processing efficiency of the garbage pushing and leveling mechanism 20 for the garbage.

[0047] As Figure 11As shown, on the basis of the above embodiments, the rotary connector 25 is a roller structure. The two ends of the roller are connection ends 250 and are respectively rotatably connected to the two connecting rods 24 of a pair of connecting rods 24. A groove 251 is concavely formed on the wheel surface in the middle of the roller, and the tensioning rope 231 is sleeved in the groove 251 of the roller. With such a setting, when the winding motor 230 tightens the two rotary connectors 25 through the tensioning rope 231, since the roller can rotate on the connecting rod 24, the pulling rope and the rotary connector 25 are in rolling contact, which can reduce the wear between components and extend the service life of the garbage pushing and leveling mechanism 20.

[0048] As Figure 10 shown, on the basis of the above embodiments, the tensioning device 23 further includes a connecting rope 232 and a tension sensor 233. One end of the connecting rope 232 is fixedly connected to the output shaft of the winding motor 230, and the other end of the connecting rope 232 is connected to the tensioning rope 231 through the tension sensor 233. In specific implementation, a controller is arranged between the tension sensor 233 and the winding motor 230. The tension sensor 233 can monitor the tension of the winding motor 230 on the tensioning rope 231 in real time. The extrusion force of the pressing component 22 on the garbage can be indirectly obtained according to the magnitude of the tension. The controller reasonably and automatically controls the rotation action of the winding motor 230 according to the tension detected by the tension sensor 233, so as to ensure that the extrusion force of the pressing component 22 on the garbage is in a relatively stable state, so as to avoid too large or too small pressure, because too large pressure will damage the corresponding components of the garbage pushing and leveling mechanism 20, and too small pressure will not achieve a good compression effect.

[0049] The hanging bucket device of the common hanging bucket sanitation vehicle on the market is generally connected to the cover plate covering the garbage inlet through a connecting rod. When the cover plate is turned up and down, the hanging bucket device can be pulled to slide up and down along the outer wall of the carriage through the connecting rod, which can not only realize the dumping of garbage, but also timely open and close the cover plate at the garbage inlet. However, since the cover plate is generally rotatably connected to the carriage in an up-and-down flipping manner, and in some old communities, there are many low-altitude hanging wires, electric wires, branches, etc. When operating in these environments, the operation range of the sanitation vehicle is restricted and the operation safety is not high. To solve this problem, as Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 shown, on the basis of the above embodiments, in this embodiment, two cover plates 31 capable of relatively moving in opposite directions along the horizontal direction are arranged on the carriage 10 at the garbage inlet 11. It can be understood that the horizontal direction is any direction in the plane where the vehicle is placed, including the first horizontal direction and the second horizontal direction. In Figure 7In the figure, the horizontal direction specifically refers to the length direction of the carriage 10. Specifically, the cover plate 31 is slidably connected to the top of the carriage 10 along the first horizontal direction through the first slide rail 37. The garbage dumping structure 30 includes a connecting frame 32, a barrel fixing component 33 and a rotating drive component 34. The connecting frame 32 is movably arranged on the side of the carriage 10 in the vertical direction. Specifically, the connecting frame 32 is slidably connected to the side of the carriage 10 in the vertical direction through the second slide rail 38. The connecting frame 32 has a first height position and a second height position in the vertical direction, and the second height position is higher than the first height position. The two sides of the connecting frame 32 are movably connected to the two cover plates 31 through two connecting rods 39; the barrel fixing component 33 is rotatably connected to the connecting frame 32 and can fix the garbage can 40; the rotating drive component 34 is configured to drive the barrel fixing component 33 to flip toward the garbage inlet 11 when the barrel fixing component 33 moves to the second height position. With such arrangement, when it is necessary to pour the garbage in the garbage bin 40 from the garbage inlet 11 into the carriage 10, the garbage bin 40 is first fixed on the fixed barrel component 33, and then the two cover plates 31 are moved in opposite directions in the horizontal direction to gradually expose the garbage inlet 11. At the same time, the cover plate 31 pulls the connecting frame 32, the fixed barrel component 33 and the garbage bin 40 upward together through the connecting rod 39. When the fixed barrel component 33 moves to the second height position, the rotating driving component 34 drives the fixed barrel component 33 to flip toward the garbage inlet 11, so that the garbage in the garbage bin 40 on the fixed barrel component 33 is poured from the garbage inlet 11 into the carriage 10. After the garbage dumping is completed, the two cover plates 31 are moved in opposite directions in the horizontal direction, and the garbage inlet 11 is closed while pushing the connecting frame 32, the fixed barrel component 33 and the garbage bin 40 downward to reset to the first height position. It can be seen that by adopting the above design, by adopting the flat-opening cover plate 31, the actual operating space required by the sanitation vehicle can be effectively reduced and the operating range of the sanitation vehicle can be expanded.

[0050] like Figure 12 As shown, on the basis of the above embodiment, the fixed barrel component 33 is a semi-enclosed box structure capable of accommodating the trash can 40, the side of the fixed barrel component 33 facing away from the carriage 10 is open, and a limit baffle 330 for limiting the movement of the casters 41 of the trash can 40 along the height direction of the fixed barrel component 33 is fixedly provided on the inner side of the fixed barrel component 33. The fixed barrel component 33 with this structure is not only convenient for the user to fix the trash can 40 on the fixed barrel component 33, but also can prevent the trash can 40 from falling into the carriage 10 during the turning process of the fixed barrel component 33.

[0051] like Figure 12As shown, on the basis of the above embodiments, a front end plate 331 that can be turned over vertically is provided at the front end of the bucket fixing member 33. The front end plate 331 is rotatably connected to the bucket fixing member 33 through a movable shaft 332. One end of the movable shaft 332 is fixed to the bucket fixing member 33, and the other end is connected with a fastening screw 333 that can fix the angle of the front end plate 331. With such a setting, the trash can 40 with casters 41 at the bottom can enter the inner side of the bucket fixing member 33 through the front end plate 331 at the front end of the bucket fixing member 33. Since the angle of the front end plate 331 can be adjusted, the bucket fixing member 33 can adapt to various uneven road surfaces. In addition, by fixing the front end plate 331 to the bucket fixing member 33 with the fastening screw 333, the shaking of the front end plate 331 during the movement and turning of the bucket fixing member 33 can be reduced.

[0052] As Figure 3 shown, on the basis of the above embodiments, the rotation driving member 34 includes a gear 340 and a rack 341. The gear 340 is fixedly installed on the bucket fixing member 33, and the rack 341 is fixed on the carriage 10 adjacent to the garbage input port 11. When the bucket fixing member 33 moves to the second height position, it is turned upward through the engagement of the gear 340 and the rack 341. Of course, as long as the bucket fixing member 33 can be driven to turn towards the garbage input port 11 when the bucket fixing member 33 moves to the second height position, there is no particular limitation on the specific structural form of the rotation driving member 34.

[0053] In order to realize the relative reverse movement of the two cover plates 31 in the horizontal direction. As Figure 1 , Figure 2 , Figure 7 and Figure 8 shown, on the basis of the above embodiments, a first reciprocating lead screw 36 driven by a driving motor 35 to rotate is provided on the top of the carriage 10. Two sets of reciprocating threads are provided on the first reciprocating lead screw 36, and the two cover plates 31 are respectively connected to the two sets of reciprocating threads. When the driving motor 35 is started, it drives the first reciprocating lead screw 36 to rotate, thereby driving the two cover plates 31 to move in opposite directions in the horizontal direction.

[0054] As Figure 8As shown, on the basis of the above embodiment, the two cover plates 31 can move in opposite directions relative to each other along the first horizontal direction, the carriage 10 is provided with a mutually parallel light rod 27 and a second reciprocating screw rod 26, the moving part 21 is connected to the light rod 27 and the second reciprocating screw rod 26, the light rod 27 is fixed on the carriage 10, the second reciprocating screw rod 26 is rotatably connected to the carriage 10 and is connected to the first reciprocating screw rod 36 through a transmission structure, specifically, the transmission structure is a belt and a pulley, a pulley is provided on each of the first reciprocating screw rod 36 and the second reciprocating screw rod 26, and the two pulleys are connected by a belt. In this way, when the driving motor 35 drives the first reciprocating screw rod 36 to rotate and drives the two cover plates 31 to open and close, it will also drive the second reciprocating screw rod 26 to rotate through the belt and the pulley, thereby driving the moving part 21 to reciprocate along the first horizontal direction. The opening of the carriage 10, the dumping of garbage, the leveling of garbage and the compaction of garbage are realized synchronously. This can further improve the efficiency of garbage disposal.

[0055] 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.
