DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0025] Please refer to Figures 1-4 In the embodiments of the present application, the anti-material accumulation mechanism of the bucket elevator comprises an elevator body 1, a material collecting bin 2, an auger conveying mechanism 3 and a blocking mechanism 4. The elevator body 1 can lift the material to a high place. The feed hopper 11 is fixedly connected to one side of the elevator body 1 and located at the feed inlet. The discharge port is arranged at one side of the top of the elevator body 1. The material collecting port 12 is through-holed in the bottom surface of the cavity of the elevator body 1. The through hole is through-holed in the bottom surface of the feed hopper 11 and close to the elevator body 1. The material collecting bin 2 is installed and fixed to the bottom surface of the elevator body 1 and fixed to the ground. The material collecting bin 2 is communicated with the material collecting port 12 and can collect the spilled material. The auger conveying mechanism 3 is arranged on one side of the elevator body 1 and fixed to the ground, and is used for conveying the material in the material collecting bin 2 to the feed hopper 11. The blocking mechanism 4 is arranged between the elevator body 1 and the feed hopper 11 and is used for blocking the feed inlet of the elevator body 1. The blocking mechanism 4 comprises the L-shaped plate 41 which is through-holed and slidably arranged in the through hole.

[0026] Specifically, the material to be conveyed is first poured into the feed hopper 11, and the elevator body 1 is started simultaneously, causing multiple hoppers inside to rotate. When a hopper moves to a position below the feed hopper 11, its upward movement causes the L-shaped plate 41 to move downward. The downward-moving L-shaped plate 41 opens the feed inlet of the elevator body 1, allowing the material in the feed hopper 11 to fall into the elevator body 1. The upward-moving hopper catches the falling material until it rises a certain distance. Then, the L-shaped plate 41 returns to its original position, blocking the feed inlet of the elevator body 1. This process continues until the next hopper moves below the feed hopper 11 and causes the L-shaped plate 41 to move downward. This repeated operation conveys the material to a higher position. When the hopper catches the material, some material may fall into the bottom of the elevator body 1. Because the bottom surface of the chamber of the elevator body 1 is provided with a material collection port 12, the material falling into the bottom of the elevator body 1 falls into the collection bin 2 through the material collection port 12, and is then transported to the feed hopper 11 through the connecting pipe 21 and the auger conveying mechanism 3. After the hopper moves to a specified position and continues to move, the L-shaped plate 41 can open the feed port of the elevator body 1, allowing most of the material falling into the elevator body 1 to enter the hopper. Then, after the hopper rises to a certain distance, the L-shaped plate 41 automatically returns to its original position and blocks the feed port, preventing most of the material from falling into the bottom of the elevator body 1 and causing blockage. Therefore, it can avoid material accumulation, prevent the hopper from colliding with the accumulated material and being subjected to a large reverse force, thereby improving the service life of the hopper and improving the material conveying efficiency.

[0027] Example 1

[0028] like Figure 2 As shown, in this embodiment, a connecting pipe 21 that communicates with the inside of the collecting bin 2 is fixedly connected to the bottom end of one side of the collecting bin 2 near the auger conveyor mechanism 3. One end of the connecting pipe 21 is fixedly connected to the feed end of the auger conveyor mechanism 3. The inner bottom surface of the collecting bin 2 is a sloping structure.

[0029] In this embodiment, a small portion of the material falling into the bottom of the elevator body 1 falls into the collection bin 2 from the collection port 12. Then, under the action of the inclined surface of the collection bin 2, it rolls into the auger conveyor mechanism 3 through the connecting pipe 21. The auger conveyor mechanism 3 can transport the material to the feed hopper 11, which can prevent the material at the bottom of the elevator body 1 from accumulating too much and affecting the normal movement of the hopper.

[0030] Example 2

[0031] like Figure 3 and Figure 4As shown, in this embodiment, the side of the aggregate bin 2 and below the feeding hopper 11 is fixedly connected with an extension plate 22, the top surface of the extension plate 22 is fixedly connected with two symmetrical slide rods one 42 which slide through the L-shaped plate 41, the outer side of the L-shaped plate 41 and the extension plate 22 is fixedly connected with springs 43, the side of the hopper in the elevator body 1 is fixedly connected with a magnet one 13, the inner wall of the elevator body 1 is slidably connected with a moving plate 44, the bottom surface of the moving plate 44 is fixedly connected with two pull ropes 45 which penetrate through the elevator body 1 and are fixedly connected with the L-shaped plate 41, one side of the moving plate 44 is embeddedly fixedly connected with a magnet two 46 which is attracted to the magnet one 13, the inner wall of the elevator body 1 and below the moving plate 44 is fixedly connected with a fixed plate 47, the top surface of the fixed plate 47 is fixedly connected with two slide rods two 48 which slide through the moving plate 44, and the top end of the slide rods one 42 and the slide rods two 48 are fixedly connected with limit blocks.

[0032] In this embodiment, when the hopper moves to contact the moving plate 44, the magnet one 13 is attracted to the magnet two 46, so that the upwardly moving hopper can drive the moving plate 44 to move upward, and the upward movement of the moving plate 44 can drive the L-shaped plate 41 to move downward and compress the two springs 43, at this time the feeding port of the elevator body 1 is opened, the material in the feeding hopper 11 falls into the corresponding hopper, until the moving plate 44 moves to contact the limit block at the corresponding position and cannot continue to move upward with the hopper, at this time the upwardly moving hopper is separated from the moving plate 44, and the moving plate 44 moves downward under the action of its own gravity, and the L-shaped plate 41 blocks the feeding port of the elevator body 1 under the elastic action of the two springs 43, until the next hopper moves upward to drive the L-shaped plate 41 to move downward to open the feeding port, so that a large amount of material can be prevented from accumulating at the bottom of the elevator body 1.
