Description

Technical Field

[0001] This invention relates to the field of sanitation equipment technology, specifically to a garbage can clamping structure. Background Technology

[0002] Garbage trucks are vehicles used for cleaning city streets. During cleaning operations, workers place garbage bins into the clamping structure on the garbage truck to complete the dumping and collection of garbage. However, some existing garbage bin clamping structures have fixed dimensions, which can only be used for garbage bins of a fixed size. When the size of the garbage bin does not match the size of the clamping structure, the clamps may loosen or fall off, thus affecting the cleaning work. Summary of the Invention

[0003] In view of the above-mentioned technical deficiencies, the purpose of this invention is to provide a trash can clamping structure that can be adapted to clamp trash cans of various sizes, thereby improving its applicability.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a trash can clamping structure, comprising: support; Lifting assembly, the lifting assembly is mounted on the bracket; A baffle is mounted on the lifting assembly. Clamping ring assembly, the clamping ring assembly is disposed on the side wall of the baffle away from the lifting assembly; The clamping arm assembly has two components, which are symmetrically arranged on both sides of the clamping ring assembly. The lifting assembly includes a lifting cylinder mounted on a bracket, a mounting seat on the piston rod of the lifting cylinder, and a baffle mounted on the side wall of the mounting seat. The clamping ring assembly includes a clamping ring movably mounted on a baffle, and the side wall of the baffle is provided with a ring groove that is adapted to the shape and size of the clamping ring. The clamping arm assembly includes a clamping motor mounted on a baffle, a rotating arm mounted on the output shaft of the clamping motor, an adjusting motor mounted on the end of the rotating arm away from the clamping motor, and an adjusting clamping arm mounted on the output shaft of the adjusting motor.

[0005] Preferably, the bracket has a left column and a right column arranged in parallel at intervals. The left and right columns have left guide grooves and right guide grooves respectively on their opposite side walls. The mounting base has a left slider and a right slider respectively on its opposite side walls. The left slider and the right slider are slidably disposed in the left guide groove and the right guide groove respectively, so that when the lifting cylinder drives the mounting base to move up and down to adjust its position, the movement of the mounting base can be guaranteed to be stable.

[0006] Preferably, the baffle is provided with a double-headed cylinder and two clamping rings, which are arc-shaped structures with two opposing arc openings. The two clamping rings are respectively set on the two piston rods of the double-headed cylinder. The double-headed cylinder can drive the two clamping rings to open and close, thereby clamping the trash can.

[0007] Preferably, a tilting groove is inclinedly provided on the top surface of the mounting base. A tilting motor is provided at one end of the tilting groove near the double-headed cylinder. A cylinder seat is provided on the output shaft of the tilting motor. The double-headed cylinder is mounted on the cylinder seat. The height of the tilting groove near the double-headed cylinder is less than the height of the tilting groove away from the double-headed cylinder. When the trash can is tilted, the trash in the trash can can be tilted into the tilting groove for collection.

[0008] Preferably, the adjusting clamp arm is provided with an adjusting chuck assembly, the adjusting chuck assembly comprising: An arc-shaped rod is mounted on the side wall of the adjusting clamp arm, and the arc-shaped rod rotates about the output shaft of the adjusting motor. Chucks, multiple chucks are provided, and multiple chucks are equally spaced and fitted on the outside of the arc-shaped rod; The hook is rotatably mounted on the rotating arm via a torsion spring-loaded shaft. The end of the hook away from the rotating arm is movably locked onto the outside of the arc-shaped rod between two adjacent chucks. This allows for adjustment of the position of the adjusting clamp arm by rotating the motor according to different sizes of trash cans. Then, the end of the hook away from the rotating arm is locked onto the outside of the arc-shaped rod at the corresponding position. At this time, the end of the hook away from the rotating arm is located between two adjacent chucks at the corresponding position, which helps to prevent the adjusting clamp arm from loosening.

[0009] Preferably, a polygonal locking rod is provided on the top surface of the adjusting clamp arm, and a locking external threaded rod is movably provided below the polygonal locking rod. An internal threaded sleeve corresponding to the position of the locking external threaded rod is provided through the baffle. The end of the locking external threaded rod away from the baffle is threadedly connected to the internal threaded sleeve. This allows the polygonal locking rod to better contact the edge of the garbage can opening when the adjusting motor drives the adjusting clamp arm to rotate and adjust its position, thereby clamping the garbage can. At the same time, when it is not necessary to rotate the adjusting clamp arm, the end of the locking external threaded rod away from the baffle can be threadedly connected to the internal threaded sleeve, thereby keeping the position of the adjusting clamp arm stable.

[0010] Preferably, the length direction of the polygonal clamp is the same as the length direction of the output shaft of the adjusting motor, so that the position can be adjusted by adjusting the motor to drive the adjusting clamp arm to rotate according to different sizes of trash cans. The polygonal clamp can then better contact the edge of the trash can opening, thereby clamping the trash can.

[0011] Preferably, the depth of the groove is greater than the thickness of the clamping ring, so that the clamping ring can be stored in the groove without causing interference when clamping the trash can.

[0012] The beneficial effects of the present invention are as follows: 1. The clamping ring assembly provided in the present invention can clamp garbage cans of different sizes by adjusting the distance between the two clamping rings through a double-headed cylinder, thereby improving its applicability.

[0013] 2. The lifting cylinder can drive the clamping arm assembly to adjust its position in the vertical direction, so that the clamping arm assembly can clamp trash cans of different heights; at the same time, the clamping motor drives the rotating arm and the adjusting arm to adjust their positions, so as to clamp trash cans of different sizes or shapes.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1 like Figures 1 to 4 As shown, the present invention provides a trash can clamping structure, including a bracket 1; a lifting assembly 2 disposed on the bracket 1; a baffle 3 disposed on the lifting assembly 2; a clamping ring assembly 4 disposed on the side wall of the baffle 3 away from the lifting assembly 2; two clamping arm assemblies 5 are provided, the two clamping arm assemblies 5 being symmetrically disposed on both sides of the clamping ring assembly 4; the lifting assembly 2 includes a lifting cylinder 21 disposed on the bracket 1, a mounting seat 22 disposed on the piston rod of the lifting cylinder 21, and the baffle 3 disposed on the side wall of the mounting seat 22; the clamping ring assembly 4 includes a clamping ring 41 movably disposed on the baffle 3, and a ring groove 42 disposed on the side wall of the baffle 3 that is adapted to the shape and size of the clamping ring 41; the clamping arm assembly 5 includes a clamping motor 51 disposed on the baffle 3, a rotating arm 52 disposed on the output shaft of the clamping motor 51, an adjusting motor 53 disposed at the end of the rotating arm 52 away from the clamping motor 51, and an adjusting clamping arm 54 disposed on the output shaft of the adjusting motor 53.

[0024] First, install the bracket 1 at the corresponding position on the sanitation garbage truck according to the usage requirements (that is, install this garbage bin clamping structure on the tipping mechanism of the sanitation garbage truck. The tipping mechanism of the sanitation garbage truck is existing technology, so it will not be described in detail here. This allows the garbage bin to be tipped after being clamped by this garbage bin clamping structure, so as to empty the garbage inside the garbage bin). The lifting cylinder 21 can drive the mounting base 22 and the baffle 3 to adjust the position of the garbage bins of different heights in the vertical direction, so as to facilitate the clamping ring assembly 4 and the clamping arm assembly 5 to clamp.

[0025] The trash can can also be clamped by the clamping ring 41; when the clamping ring 41 is not in use, it can be stored in the ring groove 42 to prevent interference between the clamping ring 41 and the trash can when the clamping arm assembly 5 is used to clamp the trash can.

[0026] Alternatively, the clamping arm assembly 5 can be used to clamp the trash can. Depending on the different diameters of the trash can, the clamping motor 51 is started to drive the rotating arm 52 to rotate; at the same time, the adjusting motor 53 is started to drive the adjusting clamping arm 54 to rotate, thereby clamping the trash can (at the same time, under the action of the baffle 3, that is, when the clamping arm assembly 5 is used to clamp the trash can, the outer peripheral wall of the trash can can abut against the baffle 3).

[0027] The bracket 1 has a left column 11 and a right column 12 arranged parallel to each other. The left guide groove 111 and the right guide groove 121 are respectively provided on the opposite side walls of the left column 11 and the right column 12. The mounting base 22 has a left slider 221 and a right slider 222 respectively provided on the opposite side walls. The left slider 221 and the right slider 222 are slidably disposed in the left guide groove 111 and the right guide groove 121, so that when the lifting cylinder 21 drives the mounting base 22 to move up and down to adjust the position, the left slider 221 and the right slider 222 slide in the left guide groove 111 and the right guide groove 121 respectively, thereby ensuring that the mounting base 22 moves smoothly in the vertical direction.

[0028] Example 2 Based on Example 1, such as Figures 1 to 3 As shown, a double-headed cylinder 43 is provided on the baffle 3, and two clamping rings 41 are provided. The two clamping rings 41 are two arc-shaped structures with opposite arc openings. The two clamping rings 41 are respectively set on the two piston rods of the double-headed cylinder 43. When the clamping arm assembly 5 is not used, the double-headed cylinder 43 can be started first to move the two clamping rings 41 in opposite directions, thereby increasing the distance between the two clamping rings 41, so that the garbage can can be placed between the two clamping rings 41. Then, the double-headed cylinder 43 is started again to drive the two clamping rings 41 to move closer to the two clamping rings 41 until the inner circumferential wall of the two clamping rings 41 abuts against the outer circumferential wall of the garbage can, thereby achieving the clamping of the garbage can (the position can also be adjusted by starting the lifting cylinder 21 to drive the baffle 3 and the clamping ring assembly 4 according to the different heights of the garbage can, so as to facilitate clamping the garbage can at the opening position by the two clamping rings 41).

[0029] The depth of the groove 42 is greater than the thickness of the clamping ring 41, so that when the clamping ring 41 is not in use, it can be stored in the groove 42, so that when clamping the trash can, there will be no interference between the clamping ring 41 and the trash can.

[0030] A tilting groove 31 is inclinedly provided on the top surface of the mounting base 22. A tilting motor 44 is provided at one end of the tilting groove 31 near the double-headed cylinder 43. A cylinder seat 441 is provided on the output shaft of the tilting motor 44. The double-headed cylinder 43 is mounted on the cylinder seat 441. The height of the tilting groove 31 near the double-headed cylinder 43 is less than the height of the tilting groove 31 away from the double-headed cylinder 43. When the trash can is tilted, the trash inside can be tilted into the tilting groove 31 and can slide down into the tilting groove 31 for collection. The diameter of the trash can held by the clamping ring 41 is larger than the distance between the left column 11 and the right column 12, which makes it easier to tilt the trash can after it is clamped by the clamping ring 41. The opening of the trash can can abut against the left column 11 and the right column 12, which can both allow the trash to be tilted out and prevent the trash can from falling off the clamping ring 41.

[0031] Example 3 Based on Example 1, such as Figures 3 to 6 As shown, an adjusting chuck assembly 6 is provided on the adjusting clamp arm 54. The adjusting chuck assembly 6 includes an arc-shaped rod 61, which is disposed on the side wall of the adjusting clamp arm 54 and rotates about the output shaft of the adjusting motor 53. Multiple chucks 62 are provided and are equidistantly sleeved on the outside of the arc-shaped rod 61. Hooks 63 are rotatably disposed on the rotating arm 52 via a rotating shaft 631 with a torsion spring. The end of the hook 63 away from the rotating arm 52 is movably locked on the outside of the arc-shaped rod 61 between two adjacent chucks 62. A polygonal locking rod 7 is provided on the top surface of the adjusting clamp arm 54. A locking external thread rod 8 is movably disposed below the polygonal locking rod 7. An internal thread sleeve 81 corresponding to the position of the locking external thread rod 8 is disposed on the baffle 3. The end of the locking external thread rod 8 away from the baffle 3 is threadedly connected to the internal thread sleeve 81. The length direction of the polygonal locking rod 7 is the same as the length direction of the output shaft of the adjusting motor 53.

[0032] When it is necessary to clamp trash cans of different diameters, first rotate the end of the locking external thread rod 8 away from the baffle 3 to the outside of the internal thread sleeve 81 (so that the end of the locking external thread rod 8 away from the baffle 3 is separated from the internal thread sleeve 81); then start the adjusting motor 53 to drive the adjusting clamp arm 54 and the polygonal clamp rod 7 to rotate and adjust the position. At this time, the arc rod 61 can be rotated at the same time (the arc rod 61 rotates with the output shaft of the adjusting motor 53 as the axis), so that the distance between the two polygonal clamp rods 7 can be adjusted, so that the two polygonal clamp rods 7 can be clamped on the outer wall of the trash can, thus clamping the trash can; after the position of the adjusting clamp arm 54 is adjusted, the end of the hook 63 away from the rotating arm 52 is locked on the outside of the arc rod 61 at the corresponding position (at this time, the end of the hook 63 away from the rotating arm 52 is located between the two adjacent chucks 62 at the corresponding position), which helps to prevent the adjusting clamp arm 54 from loosening, thereby improving the clamping effect on the trash can.

[0033] When the adjusting motor 53 drives the adjusting clamp arm 54 to rotate and adjust the position, the polygonal clamping rod 7 can better contact the edge of the garbage can opening (the polygonal clamping rod 7 can be made into a straight rod or an arc rod according to the shape of the garbage can, which helps to increase the contact surface with rectangular or round garbage cans when clamping), making it easy to clamp garbage cans of different sizes and shapes; at the same time, when it is not necessary to rotate the adjusting clamp arm 54, the end of the locking external thread rod 8 away from the baffle 3 can be threaded into the internal thread sleeve 81, so as to keep the position of the adjusting clamp arm 54 stable.

[0034] The distance between the two adjusting clamping arms 54 can be adjusted by starting the clamping motor 51 to drive the rotating arm 52 to rotate, making it suitable for clamping garbage cans of different diameters and improving its applicability.

[0035] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
