Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to an elevator bucket cleaning device. Background Technology

[0002] A bucket elevator, also known as a bucket conveyor, is a mechanical device used for vertically or inclinedly conveying granular or powdery materials. It consists of one or more bucket-shaped material containers (buckets), which lift the material from the bottom or inlet to the top or outlet via a chain or belt. Bucket elevators are widely used in industries such as mining, metallurgy, chemicals, building materials, and food processing. Their advantages include large conveying capacity, simple structure, and small footprint. Depending on the properties of the material and process requirements, bucket elevators can be designed and selected with different bucket shapes, chain or belt materials, and drive methods.

[0003] During the operation of the elevator, due to factors such as the properties of the material and operating conditions, some material may accumulate and pile up in the hopper, affecting the normal operation of the elevator and the continuous conveying of materials. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a bucket cleaning device for elevators, which has the advantages of automatically cleaning the bucket, preventing material accumulation, and having replaceable springs, thus solving the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a bucket cleaning device for a hoist, including a frame, a belt inside the frame, a bucket fixed on the belt, a mounting frame on the top of the frame, a support frame fixed on the side wall of the mounting frame away from the bucket, an upper gear and a lower gear rotatably connected to one side of the support frame via a bearing seat, the upper gear being above the lower gear, a rotating plate fixed on the outer wall of the upper gear, both the upper and lower gears meshing with the side of the tooth plate, the tooth plate being movably connected to the inner side of the support frame, a movable rod below the lower gear meshing with it through a tooth groove on the movable rod, one end of the movable rod passing through the mounting frame and fixedly connected to a collision block, a spring sleeved on the other end of the movable rod, and the other end of the movable rod being movably connected to the support plate, the support plate being fixed to the side wall of the mounting frame.

[0006] Preferably, sliders are fixed to both sides of the toothed plate, and the sliders are slidably disposed in the strip holes opened on the side walls of the support frame.

[0007] Preferably, the bottom of the toothed plate has a through hole for the movement of the movable rod.

[0008] Preferably, the material of the collision block is rubber.

[0009] Preferably, the other end of the movable rod is fitted inside the fixed sleeve, the fixed sleeve is fitted on the top of the support plate, and the top of the support plate is also threaded with a bolt, one end of which is screwed into a screw hole on the outer wall of the fixed sleeve.

[0010] Preferably, a limiting rod is fixed to the top of the support frame, and the bottom of the limiting rod abuts against the surface of the rotating plate.

[0011] By employing the above technical solution, this utility model provides a bucket cleaning device for a hoist, which has at least the following beneficial effects:

[0012] 1. The bucket cleaning device of this elevator, through the setting of components such as upper gear, rotating plate, toothed plate, lower gear, movable rod, collision block and spring, etc., when the bucket reaches the top of the frame and dumps material, the bucket will first squeeze the rotating plate and force it to rotate, thereby causing the movable rod to drive the collision block to move outward. At this time, the spring is in a compressed state. When the bucket is separated from the rotating plate, under the action of the spring, the movable rod pushes the collision block to quickly reset, thereby producing an impact effect on the outer wall of the bucket, generating vibration force, loosening the material in the bucket and cleaning it out. This structure can realize the automatic cleaning of the bucket, ensuring the normal operation of the elevator and the continuous conveying of materials.

[0013] 2. The bucket cleaning device of this elevator is equipped with a fixed sleeve, a support plate and bolts. After removing the bolts, the fixed sleeve and spring can be removed together, which makes it easy to replace the spring and avoids the problem of poor impact effect caused by the reduction of spring elasticity after long-term use.

[0021] 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.

[0022] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a cleaning device for a hoist hopper 3.

[0023] Example 1:

[0024] Combination Figure 1-4 As shown, the present invention provides a cleaning device for a bucket 3 of a hoist, including a frame 1, a belt 2 inside the frame 1, a bucket 3 fixed on the belt 2, a mounting frame 4 on the top of the frame 1, a support frame 5 fixedly connected to the side wall of the mounting frame 4 away from the bucket 3, an upper gear 6 and a lower gear 9 rotatably connected to one side of the support frame 5 via a bearing seat, the upper gear 6 being above the lower gear 9, and a rotating plate 7 fixedly connected to the outer wall of the upper gear 6. By setting the rotating plate 7, the rotating plate 7 can generate rotational power under the pressure of the bucket 3, thereby providing power for the energy storage of the spring 13. Both the upper gear 6 and the lower gear 9 are connected to the side of the toothed plate 8. The gear plate 8 is movably connected to the inner side of the support frame 5. The design of the gear plate 8 provides a basis for the linkage of the upper gear 6 and the lower gear 9. The lower gear 9 is provided with a movable rod 10 below it and meshes with it through the tooth groove on the movable rod 10. One end of the movable rod 10 passes through the mounting frame 4 and is fixedly connected to a collision block 11. The collision block 11 can be used to impact the hopper 3 to generate vibration force, so that the material in the hopper 3 is loosened and cleaned out. The other end of the movable rod 10 is fitted with a spring 13. The spring 13 can be used to store energy for impact. The other end of the movable rod 10 is movably connected to the support plate 15, and the support plate 15 is fixed to the side wall of the mounting frame 4.

[0025] Specifically, sliders 17 are fixed to both sides of the toothed plate 8, and the sliders 17 are slidably disposed in the strip holes opened on the side walls of the support frame 5; by setting the sliders 17, the toothed plate 8 is made more stable when moving up and down.

[0026] Furthermore, the bottom of the toothed plate 8 is provided with a through hole 12 for the movable rod 10 to move; the through hole 12 is designed to allow the movable rod 10 to pass through easily without causing motion interference.

[0027] Furthermore, the collision block 11 is specifically made of rubber; the rubber design can reduce the hard collision between the collision block 11 and the hopper 3, and avoid damaging the hopper 3.

[0028] Furthermore, a limiting rod 18 is fixedly connected to the top of the support frame 5, and the bottom of the limiting rod 18 abuts against the surface of the rotating plate 7; the design of the limiting rod 18 can prevent the rotating plate 7 from rotating excessively after resetting, thus limiting its rotation.

[0029] As can be seen from the embodiment, when the hopper 3 reaches the top of the frame 1 and pours material, the hopper 3 will first squeeze the rotating plate 7 and force it to rotate. The rotating plate 7 drives the upper gear 6 to rotate, and the upper gear 6 drives the lower gear 9 to rotate through the toothed plate 8. The lower gear 9 drives the collision block 11 to move outward through the meshing action with the movable rod 10. At this time, the spring 13 is in a compressed state. When the hopper 3 is separated from the rotating plate 7, under the elastic force of the spring 13, the movable rod 10 pushes the collision block 11 to quickly reset, thereby producing an impact effect on the outer wall of the hopper 3, generating vibration force, so that the material in the hopper 3 can be loosened and cleaned out.

[0030] Example 2:

[0031] Combination Figure 3 and Figure 4 As shown, based on Embodiment 1, the other end of the movable rod 10 is fitted inside the fixed sleeve 14, the fixed sleeve 14 is fitted on the top of the support plate 15, and the top of the support plate 15 is also threaded with a bolt 16, one end of the bolt 16 is screwed into the screw hole on the outer wall of the fixed sleeve 14.

[0032] As can be seen from the embodiment, when the elasticity of the spring 13 decreases after long-term use, the fixing sleeve 14 and the spring 13 can be removed together after removing the bolt 16, so that the spring 13 can be replaced.

[0033] As can be seen from the above embodiments, the operation of this device is as follows: when the hopper 3 reaches the top of the frame 1 and pours material, the hopper 3 will first squeeze the rotating plate 7 and force it to rotate. The rotating plate 7 drives the upper gear 6 to rotate, and the upper gear 6 drives the lower gear 9 to rotate through the toothed plate 8. The lower gear 9 drives the collision block 11 to move outward through the meshing action with the movable rod 10. At this time, the spring 13 is in a compressed state. When the hopper 3 is separated from the rotating plate 7, under the elastic force of the spring 13, the movable rod 10 pushes the collision block 11 to quickly reset, thereby producing an impact effect on the outer wall of the hopper 3, generating vibration force, loosening the material in the hopper 3 and cleaning it out. This operation is repeated to produce an impact effect on each hopper 3.
