The drive structure 13 is arranged on the fixed track 12, and the fixed track 12 is connected with the lifting end of the lifting mechanism 20. In this embodiment, the fixed track 12 is a square tube made of square steel, with an outer dimension of 100mmx100mmx10mm, and the inside of the square tube is hollow and has openings at both ends.

The clamping arm 11 is made of solid square steel of 40mmx60mm type.

[0050] When in use, the infrared sensor detects the position of the garbage can 1 to achieve positioning, and the garbage can 1 is opposite to the clamping mechanism 10 and located between the two clamping arms 21 at this time, wherein the garbage can 1 is provided with auxiliary handrails 2, the two auxiliary handrails 2 form a clamping position, the driving structure 13 drives the two clamping arms 11 to extend from the corresponding fixed rails 12 and accurately string the auxiliary handrails 2 pre-set on the left and right sides of the garbage can 1; then, the lifting mechanism 20 drives the two fixed rails 12 to rise at the same time, the clamping arms 11 drive the garbage can 1 to lift to a set height, and then the clamping arms 11 drive the garbage can 1 to move to the direction close to the rack 30 to the designated position through the driving of the driving structure 13, so that the garbage can 1 is hung in the designated clamping position, and then the lifting mechanism 20 drives the two fixed rails 12 to descend and reset, and the driving structure 13 drives the two clamping arms 11 to reset. In this way, the garbage can 1 does not need to be lifted manually, the physical strength of the sanitation workers can be saved, the garbage collection efficiency can be accelerated, and the occurrence of safety hazards can be avoided.

[0051] In the embodiment, the infrared sensor is arranged on the rack 30 and located at the middle position of the two groups of clamping assemblies; the garbage can 1 is provided with an electronic positioning sensor 3 corresponding to the infrared sensor. Specifically, the middle position of the garbage can 1 is provided with the electronic positioning sensor 3, when the automatic handling arm moves to the garbage can 1, the infrared sensor is operated according to the set data by the PLC electric control program, the infrared emitted by the infrared sensor is received by the electronic positioning sensor 3, and the accurate positioning of the garbage can 1 is achieved.

[0052] In the embodiment, as shown in FIG. 1, Figure 4 and Figure 6As shown, the clamping arm 11 is used to clamp one end of the garbage can 1 as the clamping end 111, and the opposite sides of the clamping arm 11 are respectively rotatably connected with a plurality of rotating members 14, and each rotating member 14 is arranged away from the clamping end 111. The clamping arm is driven to move by the driving structure 13, and each rotating member 14 rotates in the fixed track 12. Specifically, the clamping arm 11 has a clamping end 111 for clamping the garbage can 1, and the clamping end 111 is driven to extend out of the fixed track 12 by the driving structure 13. The clamping arm 11 is provided with a plurality of rotating members 14 at the other end opposite to the clamping end 111, and each rotating member 14 located at the same side of the clamping arm 11 is divided into two groups, so that the clamping arm 11 is provided with four groups of rotating members 14. The rotating member 14 located at the top is in contact with the top of the fixed track 12, and the rotating member 14 located at the bottom is in contact with the bottom of the fixed track 12. In this way, the clamping arm 11 is suspended in the fixed track 12, and the clamping arm 11 moves under the drive of the driving structure 13 to drive each rotating member 14 to rotate in the fixed track 12. Each rotating member 14 is a ball bearing, which can reduce the friction of the clamping arm 11 during movement. More specifically, two symmetrical bearings are installed on the upper and lower surfaces of the clamping arm 11 with a height of 60 mm. Two corresponding ball bearings can be installed every 2 mm, a total of 11 double x 2 rows, and a total of 44 small bearings. The length of the ball bearing installation position is 411 mm, and then it is put into the fixed track 12. A single clamping arm 11 can bear more than 150 kg of weight, and two clamping arms 11 jointly clamp the garbage can 1. In the handling work, even if the garbage in the barrel weighs 300 kg, there will be no deformation and other quality problems.

[0053] In the embodiment, the total length of each rotating member 14 arranged on the clamping arm 11 is greater than the length of the part of the clamping end 111 extending out of the fixed track 12 and used for clamping the garbage can 1. Specifically, the distance from the innermost rotating member 14 to the outermost rotating member 14 in each group of rotating members 14 is greater than the length of the clamping end 111. The part of the clamping arm 11 extending out of the fixed track 12 (i.e. the clamping end 111) can be set to 1580 mm, and the specific length can be set according to actual needs.

[0054] In the embodiment, as shown in Figures 3 to 6 The clamping arm 11 is provided with a pull ring 112, and the pull ring 112 is located at the end of the clamping end 111. Specifically, the pull ring 112 is arranged, and the clamping arm 11 can be pulled out of the fixed track 12 by manually pulling the pull ring 112, which is convenient for maintenance.

[0055] In the embodiment, as shown in Figures 3 to 6As shown, the clamping arm 11 is provided with a connecting block 113 at the end away from the pull ring 112, the connecting block 113 is connected with the driving structure 13 and can be driven to extend into the fixed track 12 through the driving structure 13. Specifically, the connecting block 113 is provided in an L shape, the driving structure 13 drives the connecting block 113 to move, the connecting block 113 drives the clamping arm 11 to move, and the connecting block 113 can move into the fixed track 12 to ensure smooth movement of the clamping arm 11.

[0056] In this embodiment, as shown in Figures 3 to 6 The driving structure 13 includes a driving motor 131 arranged on the fixed track 12, a U-shaped wheel 132 connected with the main shaft of the driving motor 131, and two pulleys 133 respectively located at both ends of the fixed track 12; the U-shaped wheel 132 is wound with a rope body 134, the rope body 134 sequentially passes through the two pulleys 133 and passes from the inside of the fixed track 12; the rope body 134 is connected with the clamping arm 11. Specifically, the driving motor 131 is controlled by a PLC electric control program, and the PLC electric control program issues an instruction to make the driving motor 131 operate. The rotation of the main shaft of the driving motor 131 drives the U-shaped wheel 132 to rotate, the rope body 134 drives the pulley 133 to rotate in the process of rotating the U-shaped wheel 132, and the connecting block 113 is connected with the rope body 134, the movement of the rope body 134 drives the connecting block 113 to move, thereby realizing the movement of the clamping arm 11. Among them, the rope body 134 is a steel wire rope.

[0057] In this embodiment, as shown in Figures 3 to 5 The lifting mechanism 20 includes a lifting motor 21 fixed to the rack 30 and a winding seat 22 connected with the main shaft of the lifting motor 21; the winding seat 22 is wound with a steel wire rope 23, one end of the steel wire rope 23 is connected with the fixed track 12. Specifically, the lifting motor 21 is controlled by a PLC electric control program, and the PLC electric control program issues an instruction to make the lifting motor 21 operate. The rotation of the main shaft of the lifting motor 21 drives the winding seat 22 to rotate, the winding seat 22 drives the steel wire rope 23 to be wound or unwound, thereby realizing driving the fixed track 12 to lift.

[0058] In this embodiment, as shown in Figures 1 to 2 and Figure 5As shown, the rack 30 is provided with a roller mechanism 40, which includes a guide plate 41 vertically arranged on the rack 30, a roller seat 42 fixed to the fixed track 12, and a roller 43 rotatably connected to the roller seat 42; the roller seat 42 is located on opposite sides of the fixed track 12; the fixed track 12 is driven by the lifting mechanism 20 to realize the rolling of the roller 43 on the guide plate 41. Specifically, the guide plate 41 is located at the bottom of the rack 30, the guide plate 41 is located between the two rollers 43 and respectively contacts the two rollers 43, the roller seat 42 is connected to the side end of the fixed track 12, and the roller 43 can rotate on the roller seat 42. When the lifting mechanism 20 drives the fixed track 12 to rise or fall in the vertical direction, the roller 43 rolls along the guide plate 41, so that the fixed track 12 can be stably lifted, and the structure is more stable. And the bottom of the guide plate 41 is provided with a limiting rod 44 located at the bottom of the roller seat 42, which can prevent the roller 43 from falling out of the guide plate 41 during rolling. Among them, four groups of roller mechanisms 40 are arranged on the fixed track 12, two on each end of the fixed track 12, when the clamping arm 11 is stretched out of the fixed track 12 and clamps the garbage can 1, as Figure 2 As shown, since the guide plate 41 is pressed tightly by the rollers 43 on both sides, the fixed track 12 still remains horizontal after one end of the clamping arm 11 is stressed. And, by the arrangement of the roller mechanism 40, only the lifting mechanism 20 needs to be arranged on one side of the rack 30 close to the clamping end 111, so that the fixed track 12 can remain horizontal during driving.

[0059] In another embodiment of the present application, a garbage collection vehicle is provided, as shown in Figure 8 including a vehicle body and the above-mentioned automatic handling arm arranged at the bottom of the vehicle body.

[0060] The automatic handling arm is directly installed below the vehicle body (chassis) of the new energy electric sanitation garbage collection vehicle, and is used for automatically stretching and retracting to handle the garbage can 1, thereby eliminating the heavy work of manually moving and handling the garbage classification can, effectively saving labor, increasing the collection and transportation speed of the garbage can 1, and improving work efficiency. The sanitation worker is relieved from the close contact with the garbage, the toxic, harmful, dirty and tiring work steps are reduced, and the sanitation worker can easily and cleanly complete the work by simply grasping the steering wheel in the vehicle cab.

[0061] In another embodiment of the present application, as shown in Figure 9 a garbage can handling method is provided, which is executed by the above-mentioned garbage collection vehicle, and includes the following steps:

[0062] S100: The garbage collection vehicle moves to the side of the garbage can 1, and the infrared sensor cooperates with the inductor of the garbage can 1 to accurately position the position of the garbage can 1.

[0063] S200: The driving structure drives the clamping arm 11 to extend out of the fixed track 12 by a set distance, and the clamping end of the clamping arm 11 accurately hooks the auxiliary handrails 2 arranged on both sides of the garbage can 1.

[0064] S300: The lifting mechanism 20 drives the corresponding clamping mechanism 10 to lift the garbage can 1 by a set height.

[0065] S400: The driving structure drives the clamping arm to move the garbage can 1 in the direction of approaching the garbage truck, and the lifting mechanism 20 drives the garbage can 1 to be hung and buckled on the clamping position.

[0066] S500: The lifting mechanism 20 and the driving structure 13 drive the clamping arm 11 to reset and be accommodated in the fixed track 12.

[0067] S600: The two motors on the roof quickly rotate the steel wire rope to lift the garbage can 1 and pour the garbage into the vehicle body, and after the garbage is poured, the garbage can 1 is reset.

[0068] S700: The driving structure 13 drives the clamping arm 11 to clamp the garbage can 1, and drives the garbage can 1 to be placed in a fixed position through the lifting mechanism 20, and finally the driving structure 13 drives the clamping arm 11 to retract and reset.

[0069] The automatic handling arm is directly installed below the vehicle body (chassis) of the new energy electric sanitation garbage truck, and is used for automatically extending and retracting the garbage can 1. When working, the driver does not need to get off the vehicle, and only needs to park the sanitation vehicle parallel to the side of the garbage classification barrel. At this time, the sanitation vehicle is about 1.45m away from the garbage classification barrel. The heavy work link of manually moving and handling the garbage classification barrel is eliminated, labor is effectively saved, the garbage can 1 collection and transportation speed is increased, and the working efficiency is improved. The sanitation worker is exempted from close contact with garbage, the work steps of toxic, harmful to health, dirty and tired are reduced, the sanitation worker can easily and cleanly sit in the vehicle cab and simply grasp the steering wheel to complete the work, thereby realizing full-mechanical automatic operation of loading and transporting household garbage. If an individual garbage can 1 is mispositioned or randomly positioned, the infrared sensor will automatically give up and find the next garbage can 1 position to continue working, so the sanitation worker only needs to sit in the cab and observe the safety of the vehicle around to control the brake.

[0070] The total length of the automated carrying arm is 2000 mm, the automated carrying arm is transversely installed on the chassis beam steel structure of the garbage collection vehicle, the component at the lowest position of the automated carrying arm is 300 mm away from the ground, so the chassis traveling is in line with the national standard, even if a large stone or other protruding objects are encountered in the underground of the living community, the chassis of the garbage collection vehicle has enough space to cross without causing damage to the chassis.

[0071] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
