Description

Technical Field

[0001] This utility model relates to the field of coal washing and beneficiation technology, specifically to a novel flipping plate action mechanism. Background Technology

[0002] A flap is a movable plate installed inside a chute. It automatically flips over by gravity, material accumulation, or mechanical linkage, thereby changing the material flow path or slowing down the flow rate. Most solutions achieve automatic reset by gravity.

[0003] Most of the flip-boards currently in use have problems such as being prone to jamming and difficulty in flipping. Utility Model Content

[0004] The present invention aims to solve the technical problems mentioned in the background section above by providing a novel flipping mechanism that flips the plate by lifting it, thereby preventing the flipping plate from jamming and reducing the intensity of manual labor.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: a novel flip-plate action mechanism, including a rotating shaft that passes laterally through both sides of the chute and is rotatably connected to the chute via a bushing. A flip plate is fixedly connected to the middle of the rotating shaft, and one end of the flip plate passes through the chute and is fixedly connected to a handle. One end of the handle is connected to a lifting mechanism via a lifting device, and the lifting mechanism lifts one end of the handle, thereby driving the rotating shaft to rotate.

[0006] In some embodiments, the two ends of the rotating shaft are polygonal cylinders, and the inside of the bushing is provided with polygonal inner holes that cooperate with the polygonal cylinders at both ends of the rotating shaft.

[0007] In some embodiments, the bushing is rotatably connected to the chute.

[0008] In some embodiments, the handle has a polygonal inner hole in the middle that mates with the polygonal cylinders at both ends of the pivot.

[0009] The advantages of this utility model compared with the prior art are: it adopts a mechanical structure, which improves the safety factor compared with the previous manual flipping; it ensures the safety and stability of the flipping plate during flipping, and the overall structure is simple and has high structural strength; it significantly reduces the frequency of manual intervention (such as manually adjusting the flipping plate, stopping and clearing blockages, etc.), and greatly reduces the labor intensity of workers while improving the continuity of operation.

[0010] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0017] The present invention will now be described in further detail.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0019] like Figures 1-5 As shown, a novel flip-plate action mechanism includes a rotating shaft 1, a bushing 2, a handle 3, a lifting device 5, a lifting mechanism 4, etc. The rotating shaft 1 is machined as follows: Figure 1 , Figure 2 The shape shown is used after it mates with the bushing 2 and handle 3. Both ends of the rotating shaft 1 are square prisms; as shown... Figure 3 , Figure 4 The bushing 2 shown has a square hole inside that mates with the square prisms at both ends of the rotating shaft 1, such as... Figure 5 The handle 3 shown has a square hole in the middle that is the same as the inside of the bushing 2;

[0020] The material is selected from high-strength alloy steel or stainless steel according to the site conditions. The combination of bushing 2, handle 3 and lifting mechanism 4 can adjust the flipping direction of the flap at will. Lifting mechanism 4 adopts lifting equipment such as hand hoist.

[0021] The rotating shaft 1 extends horizontally through both sides of the chute and is rotatably connected to the chute via the bushing 2. The bushing 2 is fixedly connected to the rotating shaft 1 and rotatably connected to the chute.

[0022] A flap is welded in the middle of the rotating shaft 1. The end of the rotating shaft 1 connected to the handle 3 has a threaded hole along its axial direction. After the central square hole of the handle 3 is fitted onto the end of the rotating shaft 1, it is hoisted with bolts to prevent it from falling off.

[0023] One end of the handle 3 is connected to the lifting mechanism 4 via the lifting device 5. The lifting mechanism 4 lifts one end of the handle 3, thereby driving the rotating shaft 1 to rotate.

[0024] This device has the advantages of low cost, simple overall structure, easy manufacturing, and high structural strength. It is suitable for various flip-plate mechanisms, and is easy to install and promote.

[0025] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
