Description
Technical Field
[0001] The utility model relates to the field of pulling mechanisms, in particular to a garbage bin holding and pulling mechanism. Background Art
[0002] The transfer of garbage bins is often achieved with the help of a hook arm, which is completed by transferring the garbage bin to the vehicle body. Currently, some garbage bins have a short transfer distance and are generally equipped with wheels at the bottom. In order to facilitate the transfer of the garbage bin, a hook is often used to cooperate with the traction structure at one end of the garbage bin.
[0003] However, when the hook is actually matched with the traction structure on the trash can, in order to facilitate the matching of the hook and the traction structure and avoid the hook and the traction structure from falling off during the transfer process, the hook is often set above the traction structure. This structure must be matched with the traction structure manually. Since it is necessary to leave operating space for the operator, the size of the hook is often larger and the weight of the hook is increased, which makes it more difficult for the operator to match the hook with the traction structure.
[0004] In view of the above problems existing in the prior art, the present invention combines many years of design and use experience in related fields with strong professional knowledge to design and manufacture a garbage bin holding and pulling mechanism to overcome the above defects. Utility Model Content
[0005] In order to solve the problems existing in the prior art, the utility model provides a garbage bin holding and pulling mechanism, which can realize the automatic coordination between the hook at the rear end of the vehicle body and the traction structure on the garbage bin body, thereby reducing the operating intensity of the operator and improving the coordination efficiency between the hook and the traction structure.
[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a garbage bin holding and pulling mechanism comprises a vehicle body, a connecting plate is provided at the rear bottom of the vehicle body, two vertical plates with a spacing are provided at the bottom of the connecting plate, and guide grooves with the same track are provided on both vertical plates, and the guide grooves comprise a horizontal straight groove and a downward arc groove connected to the horizontal straight groove, the horizontal straight groove is close to the vehicle body, and the arc groove is arranged in a direction away from the vehicle body;
[0007] One end of the two vertical plates is provided with a cylinder connecting plate, and the cylinder connecting plate is connected with an oil cylinder;
[0008] A hook arm is provided between the two vertical plates, one end of the hook arm is provided with a hook, and the other end of the hook arm is hinged to the end of the cylinder rod of the oil cylinder, and the hook arm can swing up and down around the end of the cylinder rod;
[0009] Two guide wheels are arranged on both sides of the hook arm, and the two guide wheels can cooperate with the guide groove.
[0010] Preferably, sensor fixing brackets are provided at both ends of the guide groove, the sensor fixing brackets are connected to the vertical plate, and sensors are provided on the sensor fixing brackets, and the sensors can sense the guide wheel.
[0011] Preferably, the distance between the two vertical plates is slightly larger than the width of the hook arm.
[0012] Preferably, the hook comprises a groove, one side of the groove is provided as a pulling block, and the other side of the groove is provided as a pushing block, and the height of the pushing block is greater than the height of the pulling block.
[0013] Preferably, when the oil cylinder is not extended, the hook at the end of the hook arm extends out of the vertical plate.
[0014] The utility model is beneficial in that:
[0015] 1. When the hook of the utility model cooperates with the traction structure on the garbage bin, it is only necessary for the oil cylinder to drive the hook arm to extend backward first. As the guide wheels on both sides of the hook arm move along the guide groove, when it moves to the arc groove position, the hook at the front end of the hook arm tilts downward accordingly. At this time, the hook moves to the bottom of the traction structure of the garbage bin, and then the oil cylinder retracts, and the hook gradually moves obliquely forward and upward. At this time, the hook will hook the traction structure, thereby automatically completing the cooperation between the hook and the traction structure.
[0016] 2. The hook of the utility model adopts a groove structure, with a pulling block on one side and a pushing block on the other side. The height of the pushing block is greater than the height of the pulling block. The pushing block of the hook can be used in conjunction with the traction structure to push the trash can.

[0022] In order to facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings.
[0023] like Figures 1 to 4 As shown, a garbage bin holding and pulling mechanism comprises a body (not shown), a connecting plate 1 is provided at the rear bottom of the body, two vertical plates 4 with a spacing are provided at the bottom of the connecting plate 1, and guide grooves 5 with the same track are provided on the two vertical plates 4, and the guide grooves 5 include a horizontal straight groove 51 and a downward arc groove 52 connected to the horizontal straight groove 51, the horizontal straight groove 51 is close to the body, and the arc groove 52 is arranged away from the body;
[0024] A cylinder connecting plate 2 is provided at one end of the two vertical plates 4, and a cylinder 3 is connected to the cylinder connecting plate 2. A hook arm 9 is provided between the two vertical plates 4. When the cylinder 3 is not extended, the hook at the end of the hook arm 9 extends out of the vertical plate 4. The spacing between the two vertical plates 4 is slightly larger than the width of the hook arm 9. A hook is provided at one end of the hook arm 9, and the other end of the hook arm 9 is hinged to the end of the cylinder 3 rod of the cylinder 3.

As the guide wheels 8 on both sides of the hook arm 9 move along the guide groove 5, when it moves to the arc groove 52 position, the hook at the front end of the hook arm 9 tilts downward accordingly. At this time, the hook moves to the bottom of the traction structure 10, and then the oil cylinder 3 retracts, and the hook gradually moves obliquely forward and upward. At this time, the hook will hook the traction structure 10, thereby automatically completing the cooperation between the hook and the traction structure 10.
