Description

Technical Field

[0001] This application relates to the field of garbage cleaning, and particularly to a garbage grasping structure. Background Art

[0002] With the popularization of intelligent environmental sanitation and the progress of technology, more and more cleaning robots have been put into urban environmental sanitation. Only one person needs to drive the cleaning robot or even the cleaning robot can drive automatically to clean the road surface.

[0003] Currently, the cleaning mechanisms of cleaning robots usually adopt methods such as rollers, brushes, and vacuum adsorption, which can conveniently and quickly clean the garbage on the road surface, reduce the workload of sanitation workers, and improve urban hygiene. However, cleaning robots using methods such as rollers, brushes, and vacuum adsorption are relatively difficult to clean the garbage in areas such as green belts and flower beds. Manual cleaning by sanitation workers is still required, and there is a problem that the applicability of cleaning robots for cleaning areas such as sloping sidewalks, green belts, and flower beds is relatively low. Utility Model Content

[0004] In order to improve the applicability of cleaning robots for cleaning areas such as green belts and flower beds, this application provides a garbage grasping structure.

[0005] A garbage grasping structure provided by this application adopts the following technical solution:

[0006] A garbage grasping structure includes a mounting base, a control arm, and a clamping mechanism. The mounting base is arranged on the cleaning robot body. The control arm is arranged on the mounting base and is used to drive the clamping mechanism to move. The control arm includes a support rod, a movable rod, and a first electric push rod. The support rod is arranged on the mounting base. The movable rod is hinged to the support rod. The first electric push rod is hinged to the support rod. The piston rod of the first electric push rod is hinged to the movable rod. The clamping mechanism is arranged on the movable rod and is used to clamp the garbage.

[0007] By adopting the above technical solution, after the cleaning robot travels to areas such as green belts and flower beds, the piston rod of the first electric push rod extends, driving the movable rod to rotate away from the support rod and expand. The movable rod drives the clamping mechanism to move above the inside of the green belt and flower bed. Then, the piston rod of the first electric push rod retracts, causing the movable rod to rotate towards the support rod and descend. The clamping mechanism can then move to the garbage in the inside of the green belt and flower bed and then clamp the garbage, thereby cleaning the garbage in the inside of the green belt and flower bed, effectively improving the applicability of the cleaning robot for cleaning areas such as green belts and flower beds.

[0008] Optionally, a turntable is rotatably arranged on the mounting base, the support rod is arranged on the turntable, a rotating motor is arranged on the mounting base, and the output shaft of the rotating motor is coaxially connected to the turntable.

[0009] By adopting the above technical solution, when the rotating motor is started, the output shaft of the rotating motor drives the turntable to rotate, the turntable can drive the support rod to rotate, and then drive the clamping mechanism to rotate, so as to conveniently and quickly adjust the position and angle of the clamping mechanism.

[0010] Optionally, the clamping mechanism includes a base, a claw and a control component. The base is arranged on the movable rod, two claws are hinged on the base, and the control component is arranged on the base and used to drive the two claws to approach or separate from each other.

[0011] By adopting the above technical solution, the movable rod drives the base to move, so that the two claws move to both sides of the garbage, and then the control component drives the two claws to approach each other, and the two claws can clamp the garbage. Then the movable rod drives the base to move out of areas such as the green belt and the inside of the flower bed, and the garbage can be conveniently taken out.

[0012] Optionally, the claw includes a connecting plate and a claw body. The connecting plate is hinged on the base, and a plurality of claw bodies are arranged at intervals on the connecting plate.

[0013] By adopting the above technical solution, when the two connecting plates approach each other, the multiple claw bodies on the two connecting plates approach each other to clamp the garbage. During the clamping process, the gaps between adjacent claw bodies can allow plants in the green belt and the inside of the flower bed to pass through, effectively reducing the damage to plants during the clamping and grasping of the garbage.

[0014] Optionally, the control component includes a second electric push rod and a push plate. The second electric push rod is arranged on the base, the push plate is arranged on the piston rod of the second electric push rod, inclined chutes are respectively arranged on the two connecting plates, and the inclined directions of the chutes on the two connecting plates are opposite. The two ends of the push plate slide in one chute respectively.

[0015] By adopting the above technical solution, the piston rod of the second electric push rod expands and contracts, so that the push plate moves away from or towards the second electric push rod. The two ends of the push plate are abutted against the side walls of the inclined chutes, so that the two connecting plates can be separated from or approached each other, and then the two claws can be conveniently driven to move away from or approach each other.

[0016] Optionally, the base is hinged on the movable rod, a third electric push rod is hinged on the movable rod, and the piston rod of the third electric push rod is hinged to the base.

The adsorption part is arranged on the base, and the vacuum pump is arranged on the mounting seat and communicated with the adsorption part.

[0019] By adopting the above technical solution, the base drives the adsorption part to move to the garbage, and the vacuum pump is started. The vacuum pump makes the adsorption part form a negative pressure, and the adsorption part can adsorb the garbage that is not easy to clamp, effectively improving the cleaning effect on the garbage.

Specific embodiments

[0030] The following will further describe the present application in detail with reference to the Figures 1-3 accompanying drawings.

[0031] The embodiment of the present application discloses a garbage grasping structure.

[0032] Referring to Figure 1 , the garbage grasping structure includes a mounting base 1, a control arm 2 and a clamping mechanism 3. The mounting base 1 is installed on the cleaning robot body, the control arm 2 is installed on the mounting base 1, the control arm 2 is used to drive the clamping mechanism 3 to move, the clamping mechanism 3 is installed on the control arm 2, and the clamping mechanism 3 is used to clamp the garbage.

[0033] After the cleaning robot travels to areas such as green belts and flower beds, the control arm 2 drives the clamping mechanism 3 to move into the interior of areas such as green belts and flower beds. Then, the clamping mechanism 3 clamps the garbage in areas such as green belts and flower beds, and the control arm 2 then drives the clamping mechanism 3 to move out, so as to clamp and take out the garbage in areas such as green belts and flower beds, and clean the garbage in areas such as green belts and flower beds, effectively improving the applicability of the cleaning robot for cleaning areas such as the interior of green belts and flower beds.

[0034] Referring to Figure 1 , Figure 2 , the control arm 2 includes a support rod 21, a movable rod 22 and a first electric push rod 23. A turntable 4 is rotatably installed on the base 31, and a rotating motor 5 is installed on the base 31. The output shaft of the rotating motor 5 is coaxially connected to the turntable 4. The support rod 21 is installed on the turntable 4, the movable rod 22 is hinged to the support rod 21, the first electric push rod 23 is hinged to the support rod 21, the piston rod of the first electric push rod 23 is hinged to the movable rod 22, and the clamping mechanism 3 is installed on the movable rod 22.

[0035] The rotating motor 5 starts, driving the turntable 4 to rotate. The turntable 4 drives the support rod 21 to rotate, and the support rod 21 drives the movable rod 22 and the clamping mechanism 3 to rotate above areas such as green belts and flower beds. Then, the piston rod of the first electric push rod 23 retracts, driving the movable rod 22 to rotate towards the support rod 21. The movable rod 22 can drive the clamping mechanism 3 to move down to the garbage in areas such as green belts and flower beds to clamp the garbage. By adjusting the angle of the turntable 4 through the rotating motor 5 and adjusting the position and angle of the movable rod 22 through the first electric push rod 23, the position of the clamping mechanism 3 can be adjusted conveniently and quickly, effectively improving the convenience of the clamping mechanism 3 to clamp garbage at various positions.

[0036] Refer to Figure 2 , Figure 3 , the clamping mechanism 3 includes a base 31, a claw 32, and a control component 33. The base 31 is hinged to the movable rod 22, and a third electric push rod 6 is hinged to the movable rod 22. The piston rod of the third electric push rod 6 is hinged to the base 31; two claws 32 are coaxially hinged to the base 31. The claw 32 includes a connecting plate 321 and a claw body 322. The connecting plate 321 is hinged to the base 31, and a plurality of claw bodies 322 are spaced along the length direction of each connecting plate 321. The control component 33 is installed on the base 31 and is used to drive the two connecting plates 321 to approach or move away from each other. The control component 33 includes a second electric push rod 331 and a push plate 332. The second electric push rod 331 is installed on the base 31, and the push plate 332 is installed on the piston rod of the second electric push rod 331. Two inclined chutes 3211 are opened on the two connecting plates 321, and the inclined directions of the chutes 3211 opened on the two connecting plates 321 are opposite. The two ends of the push plate 332 slide in the chutes 3211 on the two connecting plates 321 respectively.

[0037] When the piston rod of the third electric push rod 6 extends or retracts, it can drive the base 31 to rotate away from or towards the movable rod 22. The base 31 drives the claw 32 to move, thereby adjusting the angle and position of the claw 32, so that the claw 32 can adapt to the garbage at different positions, effectively improving the applicability of the claw 32 for clamping the garbage at different positions. After the claw 32 moves to the garbage, the piston rod of the second electric push rod 331 extends, causing the push plate 332 to move away from the second electric push rod 331. The two ends of the push plate 332 can respectively abut against the lower side walls of the sliding grooves 3211 obliquely opened on the connecting plate 321, causing the two connecting plates 321 to approach each other. The two connecting plates 321 drive the multiple claw bodies 322 to approach each other, so as to clamp the garbage. Then, the movable rod 22 drives the base 31 to move, and the garbage can be removed from areas such as green belts and flower beds. Then, the piston rod of the second electric push rod 331 retracts, causing the push plate 332 to abut against the upper side wall of the sliding groove 3211, and the two connecting plates 321 move away from each other, and the claw 32 no longer clamps the garbage, so that the garbage in areas such as green belts and flower beds can be taken out conveniently and quickly. And during the process of clamping the garbage, the gap between the adjacent claw bodies 322 on the same connecting plate 321 can allow the plants inside the green belt and flower bed to pass through, effectively reducing the damage to the plants during the process of clamping and grasping the garbage.

[0038] Referring to Figure 2 , Figure 3 , an adsorption mechanism 7 is installed on the base 31. The adsorption mechanism 7 is used for adsorbing garbage. The adsorption mechanism 7 includes an adsorption part 71 and a vacuum pump 72. The adsorption part 71 is rotatably installed on the base 31. The adsorption part 71 is a hollow cylinder. A plurality of adsorption holes 711 are circumferentially spaced along the length direction of the adsorption part 71 on the adsorption part 71. A driving member 8 is installed on the base 31. The driving member 8 is used for driving the adsorption part 71 to rotate. In this embodiment, the driving member 8 is a servo motor. The servo motor is installed on the base 31, and the output shaft of the servo motor is coaxially connected to the adsorption part 71. The vacuum pump 72 is installed on the mounting seat 1. A rotary joint is connected to the adsorption part 71 in a communicating manner. The vacuum pump 72 is connected to the rotary joint on the adsorption part 71 through a corrugated hose, and the position where the vacuum pump 72 is connected to the adsorption part 71 through the rotary joint is coaxial with the adsorption part 71.

[0039] When facing garbage with a small size, control the base 31 to drive the adsorption part 71 to move to the garbage, and then start the vacuum pump 72. The vacuum pump 72 causes a negative pressure to be formed inside the adsorption part 71. The adsorption part 71 can adsorb the garbage through the adsorption holes 711, effectively improving the convenience of cleaning the garbage that is not easy to clamp. And the servo motor can also be started to make the adsorption part 71 rotate, so that the other side of the adsorption part 71 adsorbs the garbage, effectively improving the cleaning efficiency of the adsorption part 71 for adsorbing the garbage.

[0040] The implementation principle of a garbage grasping structure in an embodiment of this application is as follows: The cleaning robot travels to areas such as green belts and flower beds, and then rotates the motor 5 to drive the rotating turntable 4. The turntable 4 drives the claw 32 to move above areas such as green belts and flower beds. The piston rod of the first electric push rod 23 extends and retracts, and cooperates with the piston rod of the third electric push rod 6 to extend, so that the claw 32 moves to the garbage. The piston rod of the second electric push rod 331 retracts, so that the claw 32 clamps the garbage, and can also drive the adsorption part 71 to move to the garbage. The vacuum pump 72 is started, so that the adsorption part 71 adsorbs the garbage. Then, through the cooperation of the rotating motor 5, the first electric push rod 23 and the third electric push rod 6, the garbage clamped by the claw 32 and the garbage adsorbed by the adsorption part 71 can be taken out from areas such as green belts and flower beds, effectively improving the applicability of the cleaning robot for cleaning areas such as the inside of green belts and flower beds.

[0041] The above are all the preferred embodiments of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
