[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1 Please see Figure 1-7 This embodiment provides the following technical solution: a cleaning device for the buckets of a bucket elevator, including an elevator body 1; a feed bucket 2 is fixedly connected to the bottom right side of the elevator body 1, and a discharge bucket 3 is fixedly connected to the top left side of the elevator body 1. A traction chain is rotatably connected inside the elevator body through a drive roller. Several bucket bodies are fixedly connected to the traction chain at intervals. By rotating the traction chain, the bucket bodies circulate inside the elevator body 1, thus completing the lifting and conveying of materials.

[0016] The cleaning frame 4 is fixedly connected to the elevator body 1. In some embodiments, the cleaning frame 4 is fixedly connected below the discharge hopper 3 of the elevator body 1, and the cleaning frame 4 includes two L-shaped plates, the horizontal ends of which are fixedly connected to the elevator body 1.

[0017] The flip seat 5 is rotatably connected to the cleaning frame 4 via the flip shaft 6. In some embodiments, the flip shaft 6 is located between two L-shaped plates, and both ends of the flip shaft 6 are rotatably connected to the top of the L-shaped plates on both sides. The flip seat 5 enables the striking rod 7 to rotate on the cleaning frame 4.

[0018] The striking rod 7 has its left end connected to the tilting seat 5 via a locking mechanism 8, and its right end passing through the cleaning groove on the elevator body 1 and located inside the elevator body 1. One side of the striking rod 7 is connected to the elevator body 1 via an elastic mechanism 9. When the hopper body moves to the position of the striking rod 7, the hopper body contacts the striking rod 7 and pushes the striking rod 7 to rotate downward around the tilting shaft 6, while simultaneously stretching the elastic mechanism 9. When the hopper body continues to move and disengages from the striking rod 7, the elastic force of the elastic mechanism 9 pushes the striking rod 7 to rotate in the opposite direction around the tilting shaft 6, causing the striking rod 7 to strike the outer wall of the hopper body. The impact force shakes off the residual material adhering to the inner wall of the hopper body, thus cleaning the hopper.

[0019] In some embodiments, the hopper body is struck by the striking rod 7, and the impact force is used to shake off the residual material on the inner wall of the hopper. The cleaning effect is good, which can effectively reduce the accumulation of residual material in the hopper, improve the loading capacity and conveying efficiency of the hopper, prevent the residual material from deteriorating and contaminating the subsequent materials, and extend the service life of the hopper.

[0020] The elastic mechanism 9 includes a return spring 91. The top end of the return spring 91 is hinged to the elevator body 1, and the bottom end of the return spring 91 is hinged to the striking rod 7. Through the set return spring 91, after the striking rod 7 is pushed by the hopper body, the striking rod 7 generates a pulling force on the return spring 91 during the downward rotation of the striking rod 7 around the tilting shaft 6. When the striking rod 7 is separated from the hopper body, the return spring 91 resets, causing the striking rod 7 to quickly rotate upward around the tilting shaft 6 and strike the next hopper body.

[0021] The striking rod 7 includes a screw 71 and a striking head 72. The screw 71 is detachably connected to the flipping seat 5, and the other end of the screw 71 is detachably connected to the striking head 72 via a quick-release mechanism 10. In some embodiments, the striking head 72 is a hemispherical or cylindrical structure, and its material can be selected from rubber, plastic or metal according to the characteristics of the material. For easily damaged hopper bodies, rubber or plastic striking heads 72 can be used to reduce impact damage to the hopper body; for materials with severe adhesion, metal striking heads 72 can be used to improve the cleaning effect.

[0022] like Figure 2-4 As shown, the locking mechanism 8 includes a locking hole 81 and two locking nuts 82. The locking hole 81 passes through the flip seat 5 and is adapted to the screw 71. The two locking nuts 82 are located on both sides of the flip seat 5 and are threaded onto the screw 71. Through the locking hole 81 and the two locking nuts 82, the screw 71 can be firmly fixed on the flip seat 5. When it is necessary to adjust the position of the screw 71 or disassemble the striking rod 7, it is only necessary to loosen the two locking nuts 82. The operation is simple and convenient, and it is easy to install, debug and maintain the equipment.

[0023] Example 2 like Figure 5 As shown, to facilitate the disassembly and replacement of the striking head 72, the quick-release mechanism 10 includes a locking sleeve 101 and a positioning bolt 103. The positioning cavity 102 is located at one end of the locking sleeve 101 and is adapted to fit one end of the striking head 72. The positioning bolt 103 passes through the positioning holes provided on the locking sleeve 101 and the striking head 72 and is threaded with a positioning nut 104. In some embodiments, two positioning bolts 103 are provided, and the two positioning bolts 103 are spaced apart along the radial direction of the locking sleeve 101. When the striking head 72 needs to be replaced, simply unscrew the positioning nut 104 and pull out the positioning bolt 103 to remove the striking head 72 from the positioning cavity 102. After replacing the new striking head 72, it can be fixed by the positioning bolt 103 and the positioning nut 104. The whole process does not require the use of complicated tools, which greatly improves maintenance efficiency.

[0024] Example 3 like Figure 6-7 As shown, to facilitate adjustment of the preload of the return spring 91, the elastic mechanism 9 may also include a first cylinder 92 and a return spring 91. The cylinder barrel of the first cylinder 92 is fixedly connected to the elevator body 1. A hinge seat 93 is fixedly connected to the piston end of the first cylinder 92. A spring seat 94 is hinged to the hinge seat 93. One end of the return spring 91 is fixedly connected to the spring seat 94, and the other end of the return spring 91 is hinged to the striking rod 7. By using the first cylinder 92, the preload of the return spring 91 can be adjusted, thereby adjusting the striking force of the striking rod 7, which is suitable for cleaning materials with different degrees of adhesion. When the material adhesion is severe, the first cylinder 92 can pull the spring seat 94 away from the striking rod 7, increasing the preload of the return spring 91 and increasing the striking force of the striking rod 7. When the material adhesion is slight, the first cylinder 92 can push the spring seat 94 closer to the striking rod 7, reducing the preload of the return spring 91 and avoiding excessive striking force that could damage the hopper body.

[0025] Example 4 like Figure 2-3As shown, to prevent the striking rod 7 from being in long-term contact with the hopper body, a blocking mechanism 11 is also included to block the striking rod 7. The blocking mechanism 11 includes a blocking frame 111, which is fixedly connected to the cleaning frame 4 and located below the tilting shaft 6. A second cylinder 112 is fixedly connected to the blocking frame 111, and a mounting seat 113 is fixedly connected to the piston end of the second cylinder 112. A roller 114 is rotatably connected to the mounting seat 113. In some embodiments, the blocking frame 111 is fixedly connected to the lower part of the cleaning frame 4, and the second cylinder 112 is located on the left side of the tilting shaft 6. By using the second cylinder 112 and the roller 114, the roller 114 can be pushed to move upward, pushing the tilting seat 5 to tilt around the tilting shaft 6, thereby allowing the right end of the striking rod 7 to tilt downward to the maximum extent. At this time, the striking rod 7 does not contact the hopper body. When it is not necessary to clean the hopper body, the contact between the striking rod 7 and the hopper body is reduced, increasing the service life of the striking rod 7 and the hopper body.

[0026] The working principle of this utility model is as follows: During operation, the drive roller drives the traction chain and the hopper body to move in a circular motion. When the hopper body moves to the position of the striking rod 7, the hopper body contacts the striking head 72 and pushes the striking head 72 to rotate downward around the flipping shaft 6, while stretching the return spring 91. When the hopper body continues to move and disengages from the striking head 72, the elastic force of the return spring 91 pushes the striking head 72 to rotate upward around the flipping shaft 6, so that the striking head 72 strikes the outer wall of the next hopper body, using the impact force to shake off the residual material adhering to the inner wall of the hopper body, thereby cleaning the hopper. When the material is severely stuck together, the first cylinder 92 is activated. The first cylinder 92 pulls the spring seat 94 away from the striking rod 7, increasing the preload of the return spring 91 and thus increasing the striking force of the striking rod 7. When the material is only slightly stuck together, the first cylinder 92 pushes the spring seat 94 closer to the striking rod 7, reducing the preload of the return spring 91 and preventing excessive striking force from damaging the hopper body. When it is necessary to replace the striking head 72, simply unscrew the positioning nut 104 of the quick release mechanism 10 and pull out the positioning bolt 103 to remove the old striking head 72 from the positioning cavity 102 of the locking sleeve 101. After replacing the new striking head 72, it can be fixed by the positioning bolt 103 and the positioning nut 104. When it is necessary to adjust the position of the striking rod 7 or disassemble the striking rod 7, the two locking nuts 82 of the locking mechanism 8 can be loosened to adjust or disassemble the screw 71, which is convenient to operate. When the striking head 72 does not need to contact the hopper body, the second cylinder 112 is activated to push the roller 114 to move towards the tilting seat 5. At the same time that the roller 114 contacts the tilting seat 5, since the axis of the roller 114 is located to the left of the axis of the tilting shaft 6, the roller 114 can push the tilting seat 5 to tilt around the tilting shaft 6, thereby causing the striking head 72 to tilt downward until the striking head 72 no longer contacts the hopper body.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
