[0003] Currently, when the existing bucket elevator lifts some materials with high viscosity, poor fluidity or easy caking, after such materials enter the hopper, due to their own viscosity or the influence of gravity and mechanical vibration, they are likely to accumulate at the bottom or side wall of the hopper, gradually compact and bond together. When discharging, they are likely to remain inside the hopper. The increase of the remaining materials in the hopper leads to a reduction in the actual amount of materials that can be effectively conveyed in each cycle. Therefore, this application provides a bucket elevator to meet the requirements. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a bucket elevator to solve the problem that when the existing bucket elevator lifts some materials with high viscosity, poor fluidity or easy caking, the materials are easily compacted and adhered to the inside of the hopper, resulting in inability to discharge.

Detailed Embodiments

[0028] The following describes in detail a bucket elevator provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0029] As Figure 1 , Figure 2 and Figure 4 shown, an embodiment of the present invention provides a bucket elevator, including: a feed inlet 1, a hopper 2; the hopper 2 includes: a frame body 4; a frame bottom 5 detachably arranged at the bottom of the frame body 4, and the frame bottom 5 is hollow; a plurality of tension springs 7 evenly distributed in the frame bottom 5 and centrosymmetric or axially symmetric with respect to the frame bottom 5; an airbag 8 arranged in the frame bottom 5; a dropping plate 6 movably arranged on the frame bottom 5; one side of the tension spring 7 is connected to the bottom of the inner cavity of the frame bottom 5, and the other side is connected to the dropping plate 6; one side of the airbag 8 is connected to the bottom of the inner cavity of the frame bottom 5, and the other side is connected to the dropping plate 6, and the airbag 8 is located between a plurality of tension springs 7.

[0030] By arranging the tension spring 7 and the airbag 8, when the material enters the hopper 2, the dropping plate 6 is pressed down by the weight of the material, and the tension spring 7 and the airbag 8 are compressed together; when the material is gradually discharged and the pressure decreases, the restoring force of the tension spring 7 and the natural expansion of the airbag 8 act together to drive the dropping plate 6 to move upward to completely discharge the remaining material. The airbag 8 is made of wear-resistant and corrosion-resistant materials; the frame bottom 5 and the frame body 4 are detachably designed and are connected by buckles, bolts or pin structures, which is convenient for daily cleaning and maintenance.

[0031] As Figure 5As shown, it further includes: the material dropping plate 6 is inclined. During the discharging stage, as the material is gradually discharged, the material dropping plate 6, under the combined action of the tension spring 7 and the airbag 8, pushes out all the materials inside the hopper 2, avoiding the residual materials and material adhesion inside the hopper 2.

[0032] As Figure 2 shown, it further includes: one side of the frame body 4 is gradually inclined outward from bottom to top. During the discharging stage, the material is pushed out by the material dropping plate 6 and moves along the inclined part of the frame body 4, guiding the material to leave the frame body 4 more smoothly.

[0033] As Figure 5 shown, it further includes: a groove 12 is provided inside the material dropping plate 6, and the groove 12 is located above the airbag 8; an auxiliary plate 9 is slidably arranged inside the groove 12. By providing the auxiliary plate 9, there is no gap between the material dropping plate 6 and the frame body 4, preventing the material from entering the bottom of the frame 5 through the gap.

[0034] As Figure 5 shown, it further includes: a moving plate 10 is slidably arranged inside the groove 12 and is connected to the auxiliary plate 9; a return spring 11 is provided inside the groove 12 and is connected to the moving plate 10. By providing the return spring 11, during the discharging stage, the material is pushed out by the material dropping plate 6. As the material dropping plate 6 gradually moves, it drives the auxiliary plate 9 to expand and contract, and the return spring 11 deforms, and the auxiliary plate 9 always contacts the frame body 4.

[0035] As Figure 5As shown in the figure, it also includes: One side of the auxiliary plate 9 penetrates through the material dropping plate 6. By setting streamline grooves on the surface of the material dropping plate 6, it helps the material to flow more smoothly, reducing the risk of accumulation and blockage. When the material does not enter the frame 4, when the material dropping plate 6 is in a static state, the return spring 11 remains in its natural state, and the auxiliary plate 9 is in close contact with the inner wall of the frame 4, ensuring that there is no gap between the two, in the initial state; when the material enters the frame 4, when the material dropping plate 6 moves downward due to the gravity of the material, the auxiliary plate 9 slides along the inner wall of the frame 4. At the same time, the auxiliary plate 9 shrinks into the groove 12 during the sliding process. During the shrinking process of the auxiliary plate 9, it will move along the track of the groove 12 towards the return spring 11. The movement of the auxiliary plate 9 drives the moving plate 10 to move synchronously. The moving plate 10 moves to compress the return spring 11, causing it to compress and store energy. The compression force of the return spring 11 ensures that the auxiliary plate 9 can continuously adhere to the inner wall of the frame 4 even in the contracted state, so that the auxiliary plate 9 is always in close contact with the inner wall of the frame 4 during the shrinking process. The auxiliary plate 9 and the moving plate 10 are fixedly connected. When the auxiliary plate 9 shrinks, it drives the moving plate 10 to also shrink in the groove 12. The moving plate 10 and the return spring 11 are connected. When the moving plate 10 moves, it compresses the return spring 11. At this time, the return spring 11 stores energy; when the material is discharged, as the material gradually decreases, the material dropping plate 6 is reset under the action of the tension spring 7 and the airbag 8. At the same time, the return spring 11 releases the energy stored before, pushing the moving plate 10 to extend, driving the auxiliary plate 9 to extend synchronously, so that the auxiliary plate 9 always follows the dynamic adjustment of the material dropping plate 6, making the auxiliary plate 9 always close to the inner wall of the frame 4, ensuring that there is no gap between the two. The surface of the auxiliary plate 9 is treated with an anti-stick coating or a special surface texture.

[0036] As Figure 1 and Figure 6 shown in the figure, it also includes: A feeding part 3, arranged on the feeding port 1 for uniform feeding. The feeding part 3 includes: A feeding frame 31, communicated and arranged on the feeding port 1; A guiding plate 32, rotatably arranged in the feeding frame 31; A cylinder 33, arranged on the feeding frame 31; A shunt plate 34, arranged in the feeding frame 31.

[0037] As Figure 6 shown in the figure, it also includes: The output end of the cylinder 33 extends into the feeding frame 31 and is connected to the guiding plate 32 through a connecting block. By setting the feeding frame 31, the top of the feeding frame 31 is inclined outward, facilitating the entry of the material into the feeding frame 31.

[0038] As Figure 6As shown in the figure, it further includes: a diverter plate 34 is inclined downward along the feed inlet 1, and a plurality of diversion frames are provided at the top of the diverter plate 34. By providing the diverter plate 34, the purpose is to divert the material to avoid the material piling up at the feed inlet 1. At the same time, the diverter plate 34 is inclined, which accelerates the falling speed of the material and can evenly distribute the falling material, avoiding the material piling up in one place, thus causing the phenomenon of local overweight bearing at the feed inlet 1 and reducing the blockage situation.

[0039] As Figure 6 shown in the figure, it further includes: the right side of the guide plate 32 is inclined downward along the diverter plate 34. By providing the guide plate 32, it can be composed of metal materials such as iron or stainless steel, etc., which has good firmness and is not easily deformed when contacting the material, thus reducing its service life.

[0040] The technical solution provided by the present utility model facilitates the peripheral controller to activate the movement of the cylinder 33. The material enters the feed frame 31. By controlling the contraction of the cylinder 33, the guide plate 32 rotates downward, expanding the material dropping gap, or the cylinder 33 extends, causing the guide plate 32 to rotate upward, narrowing the material dropping gap. Adjust to an appropriate spacing according to specific requirements, so that the material drops onto the diverter plate 34, diverting the material and then entering the feed inlet 1, and the material falls into the hopper 2. When the material contacts the dropping plate 6, due to the gravity, the dropping plate 6 will be slightly pressed down. At this time, the tension spring 7 and the airbag 8 start to be compressed, providing additional buffer space for the material and reducing the local compaction of the material. The driving part on the bucket elevator drives the hopper 2 to rotate. When the hopper 2 reaches the top and starts to flip for discharging, as the material is gradually discharged, the pressure on the dropping plate 6 decreases, and the tension spring 7 and the airbag 8 start to automatically reset, pushing the dropping plate 6 to move. During the movement of the dropping plate 6, a gap is generated between the dropping plate 6 and the frame body 4. At the same time, the reset spring 11 pushes the moving plate 10 to move, pushing the auxiliary plate 9, always keeping the auxiliary plate 9 in close contact with the inner wall of the frame body 4, thus ensuring that there is no gap between the dropping plate 6 and the frame body 4, helping the material to be discharged smoothly, avoiding residue, and ensuring that the hopper 2 is completely emptied.

In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without these detailed descriptions. Additionally, in order to avoid unnecessary confusion to the essence of the present utility model, well-known methods, processes, procedures, components, and circuits, etc. are not described in detail.
