Description

Technical Field

[0001] The invention belongs to the technical field of garbage disposal, and in particular relates to an automatic locking and weighable bucket-turning and lifting mechanism. Background Art

[0002] The garbage lifting mechanism is an important technical equipment in the modern urban sanitation system, mainly used to lift and flip the garbage can to facilitate the unloading and transportation of garbage. China Utility Model Patent CN219783311U provides a lifting mechanism for medical waste disinfection equipment. This technical solution mounts the lifting rod on the slideway, and uses the oil cylinder to drive the lifting rod to move up and down along the slideway. The clamping beam and the movable frame on the lifting rod are connected by a fixing bolt and a compression spring, so that the two can form a clamping gap under the restriction of the compression spring, and the opening and closing of the clamping gap is controlled by a limit block only set on the movement stroke of the clamping beam.

[0003] This technical solution uses the clamping seam to clamp and fix the edge of the trash can, so that the trash can moves up and down with the lifting rod in a clamped state. Although this mode can fix the trash can, it is only applicable to trash cans with flanges of a specific shape, and the scope of application is relatively limited; moreover, the stability of this clamping mode is not reliable enough and it is easy to slip. In addition, the lifting mechanism of the above utility model cannot weigh the weight of the trash can during operation, and there is still room for improvement in terms of function. Summary of the invention

[0004] The first technical problem to be solved by the present invention is: how to provide a trash can lifting mechanism which has a more stable locking effect on the trash can and is adaptable to a wider range of trash can configurations.

[0005] The second technical problem to be solved by the present invention is that the conventional trash can lifting mechanism does not have a weighing function.

[0006] In order to achieve the above technical objectives, the present invention adopts the following technical solutions: An automatic locking and weighable bucket lifting mechanism comprises a slide; a lifting assembly arranged at the inner wall of the slide, wherein: the lifting assembly comprises a lifting rod, a clamping beam, a movable frame, a pulley, a limit block, a fixing bolt and a compression spring, the pulley is inserted at both sides of the outer wall of the clamping beam and the movable frame through a rotating shaft, the pulley is slidably embedded in the inner wall of the slide, the limit block is fixedly arranged on the inner wall of the slide, the fixing bolt is threadedly connected to the inner wall of the clamping beam, and one end of the compression spring is fixedly arranged on the outer wall of the movable frame The other end of the compression spring is fixedly arranged at the bottom end of the fixing bolt, the bottom end of the lifting rod is rotatably sleeved on both sides of the outer wall of the movable frame, and the lifting rod is rotatably inserted into the inner wall of the slide; at the same time, it also includes a support plate, an arc-shaped hook body, and a connecting rod. The support plate is rotatably connected to the front side of the movable frame with a vertical axis, the rear end of the arc-shaped hook body is rotatably connected to the support plate with a horizontal axis, the front end of the connecting rod is rotatably connected to the middle part of the arc-shaped hook body with a horizontal axis, and the rear end of the connecting rod is rotatably connected to the clamping beam with a horizontal axis, and a tension sensor is arranged on the lifting rod.

[0007] Preferably, a dumping plate is fixedly connected to the pressing beam.

[0008] Preferably, a plurality of buckles are clamped on the outer wall of the slide.

[0009] Preferably, the clamping beam is located directly above the movable frame.

[0010] Preferably, the pouring plate is inclined.

[0011] The present invention provides two fixing modes for the trash can.

[0012] The first is the clamping and fixing mode: through the lifting assembly, the external cylinder is set on the slideway, and the lifting rod moves up and down through the extension of the external cylinder. When it is about to run to the lower dead point, the clamping beam will stop due to the limit block. The lifting rod continues to move downward and the clamping beam will separate from the movable frame, so that a clamping space appears. When the trash can is placed, the lifting rod moves upward, and the movable frame moves upward and presses the trash can under the pressure of the spring. The limit and compression spring reset functions solve the clamping and loosening functions that can only be achieved by two layers of guide rails in the hoisting machine industry. The structure is compact and simple. The second is the claw fixing mode: by controlling the spacing between the clamping beam and the movable frame, the pitch angle of the arc hook body on the support plate is controlled through the conduction of the connecting rod; based on this principle, the arc hook body is used as a claw to tightly clamp the edge of the trash can. This clamping mode is not only convenient for loading and unloading, but also has a good locking effect. No matter what angle the trash can is at during the upward process, it can maintain a stable grip.

[0013] In addition, the present invention adds a tension sensor on the lifting rod, which can weigh the trash can and improve the function of the device. Specifically, the tension sensor is installed between the lower lifting rod and the upper supporting structure, so that the tension sensor can detect the total weight on the lifting rod below it, thereby achieving the weighing effect.
