Description

Technical Field

[0001] This invention relates to the field of material conveying machinery technology, and in particular to a synchronous quantitative feeding device for solid materials in a Z-type elevator. Background Technology

[0002] In the prior art, the buckets used in Z(C) type elevators and bucket elevator conveying machinery are all filled by a synchronous quantitative feeding device for solid materials in the Z(C) type elevator bucket. The commonly used elevator bucket feeding device is directly connected to an external funnel. The filling of the bucket can be achieved by continuous feeding. However, this feeding method cannot achieve quantitative feeding, and there is a time difference between the feeding position, feeding time and the operation of each bucket. The above problems cause uneven feeding and spillage into the gaps between the buckets. To improve upon the above shortcomings, those skilled in the art have developed various material distribution and feeding devices through technological innovation. The aim is to achieve uniform material supply and prevent spillage or leakage between adjacent hoppers. A representative patent, number 201910400674.3, entitled "Z-type Elevator Feeding Device," describes a device with a distribution hopper and a fixed hopper, both with open bottoms. The fixed hopper is connected to the front via a conveying bend and a receiving port. Inside the distribution hopper, a rotating distribution cylinder surrounds the fixed hopper. A fixed shaft is located at the center of the rear end of the rotating distribution cylinder, and its periphery is fixed to the rear side wall of the distribution hopper via bearing assemblies. Multiple material drop holes are evenly distributed on the side wall of the rotating distribution cylinder. A drive wheel is coaxially fixed to the fixed shaft at the center of the rear end of the rotating distribution cylinder. The drive wheel drives the fixed shaft to rotate, simultaneously rotating the rotating distribution cylinder, thereby distributing and feeding the material. However, in actual operation, there is a large gap between the distribution bin and the fixed bin. This gap still causes material to spill around the perimeter when it is evenly distributed and the amount of material cannot be controlled. Although it improves the distribution efficiency to some extent compared with the original distribution technology, it does not fundamentally solve the problems of material leakage around the perimeter and inaccurate material supply.

[0003] In view of the shortcomings of the existing technology, the purpose of this invention is to design a synchronous quantitative feeding device for solid materials in the hopper of a Z(C) type elevator. The purpose is to improve the feeding accuracy while avoiding material leakage, and to completely avoid material spillage during feeding, which is a technical problem that needs to be solved by the existing technical personnel in this industry. Summary of the Invention

[0004] The purpose of this invention is to provide a synchronous quantitative feeding device for solid materials in a Z-type elevator. By adopting an external quantitative and rotary uniform distribution method, the material is accurately fed into the hopper, avoiding material spillage during the feeding process and improving feeding accuracy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a Z-type elevator solid material synchronous quantitative feeding device, comprising an external feeding bin, wherein a feeding port is provided at the bottom of the external feeding bin, and the feeding port is directly or indirectly connected to the elevator housing; a chain-type traction device is provided inside the elevator housing, and several hoppers are fixed by the chain-type traction device, the hoppers moving under the drive of the chain-type traction device; a rotating material equalization device is provided inside the external feeding bin, the rotating material equalization device having several isolation and distribution zones, the several isolation and distribution zones moving synchronously with the hoppers, the rotating material equalization device being connected to an external drive device and rotating under the drive to push the material in the isolation and distribution zones to the feeding port, and the material being released into the hopper from the feeding port.

[0006] The hoist housing is equipped with a bearing seat, and a drive gear plate is mounted on the bearing seat. A bevel gear I is mounted on the outer side of the drive gear plate. The rotating material distribution device is equipped with a driven shaft, and a bevel gear II is mounted on the driven shaft to mesh with bevel gear I. When the chain-type traction device uses a chain, the drive gear plate meshes with the chain.

[0007] The rotary material distribution device includes a fixed frame with several conical plates welded onto it. Each adjacent conical plate forms an isolation distribution zone. When the conical plates rotate, their bottoms push the material against the bottom surface of the outer feeding hopper. The rotation of the conical plates continuously blocks and covers the gap between adjacent hoppers, ensuring that material enters the hopper without leaking through the gap.

[0008] A support frame is provided on the top surface of the elevator housing, and the external feeding hopper is supported by the support frame.

[0009] A feeding channel is provided below the feeding port, which connects the external feeding bin and the hopper.

[0010] The beneficial effects of this invention are as follows: Through the above design, the bottom of the external feeding hopper is provided with a feeding port, which is directly or indirectly connected to the elevator housing. A chain-type traction device is installed inside the elevator housing, through which several buckets are fixed, and the buckets move under the drive of the chain-type traction device. A rotating material equalization device is installed inside the external feeding hopper, and the rotating material equalization device is provided with several isolation and distribution zones. The rotating material equalization device is connected to an external drive device and rotates under the drive, pushing the material in the isolation and distribution zones to the feeding port, from which the material is fed. The material is released into the hopper. Through the above structural setup, when the chain-type traction device drives several hoppers to move laterally, the rotating material distribution device rotates in conjunction. When the hopper reaches below the feeding port, the material in each isolated distribution area is released into the hopper through the feeding port to form a quantitative feeding. During this process, the material passes through the feeding port and corresponds to the feeding channel on the feeding port, which not only prevents material leakage but also achieves precise quantitative feeding. This invention has a simple structure and is easy to use. It overcomes the technical drawbacks of the prior art and is an ideal synchronous quantitative feeding device for solid materials in Z-type elevators. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0017] A synchronous quantitative feeding device for solid materials in a Z-type elevator includes an external feeding bin 2. The bottom of the external feeding bin 2 has a feed port 12, which is directly or indirectly connected to the elevator housing 1. The elevator housing 1 is a section of a material conveying machine, such as a section of a Z-type elevator or an L-type elevator, which primarily serves to receive materials while simultaneously conveying them. A support frame 11 is provided on the top surface of the elevator housing 1 to support and erect the external feeding bin 2.

[0018] The elevator housing 1 is equipped with a chain-type traction device, which fixes several buckets 5. In this embodiment, the chain-type traction device is a chain 6. Two chains 6 are symmetrically arranged on the left and right sides inside the elevator housing 1. The two chains 6 simultaneously support and fix the buckets 5 and provide synchronous traction.

[0019] The hopper 5 moves under the drive of the chain 6; a rotating material equalization device 3 is provided in the external feeding bin 2, and the rotating material equalization device 3 is provided with a number of isolation and distribution zones 33. The isolation and distribution zones 33 move synchronously with the hopper 5. The rotating material equalization device 3 is connected to an external driving device and rotates under the drive to push the material in the isolation and distribution zones 33 to the feeding port 12. When the hopper 5 moves to below the feeding port 12, the material is released into the hopper 5 by the feeding port 12.

[0020] More specifically, within the elevator housing 1, a bearing seat 40 is horizontally arranged on the side wall of the elevator housing 1. A drive gear 4 is arranged on the bearing seat 40, and a bevel gear I 41 is arranged on the outer side of the drive gear 4. The drive gear 4 and the bevel gear I 41 are coaxial and linked. The rotating material distribution device 3 is provided with a driven shaft 34, and a bevel gear II 35 is arranged on the driven shaft 34 to mesh with the bevel gear I 41. When the chain-type traction device uses a chain 6, the drive gear 4 and the chain 6 are meshed and linked. The chain-type traction device here can also be a conveyor belt.

[0021] like Figure 1 , 2 As shown, the rotating material distribution device 3 includes a fixed frame 31, which is arranged in a "cross" shape. Those skilled in the art can also design the fixed frame 31 into a "straight" shape, a "hexagonal" shape, or even an "octagonal" shape according to actual needs, so as to adjust the number of isolation distribution zones 33.

[0022] The present invention also discloses a molding structure for the integral isolation and material distribution zone 33, such as Figure 1 , 2As shown, several conical plates 32 are welded to the bottom of the fixed frame 31, forming an isolation distribution area 33 between each adjacent conical plate 32. When the conical plates 32 rotate, their bottoms push the material onto the bottom surface of the external feeding bin 2. The feeding port 12 is located on the bottom surface of the external feeding bin 2. When material enters the feeding port 12, it is guided into the hopper 5. When adjacent conical plates 32 are arranged, the actual material drop gap of the feeding port 12 can be controlled within a small range. While the hopper 5 moves, the conical plates 32 move synchronously to push the material into the feeding port 12, while blocking the gap between adjacent hoppers 5, thereby achieving precise feeding when the conical plates 32 and the hopper 5 move synchronously.

[0023] Furthermore, when the design length of the hopper 5 is relatively long, a single rotating material distribution device 3 may cause uneven material feeding. This technical solution can be extended, such as... Figure 1 , 2 As shown, two rotating material equalization devices 3 are symmetrically arranged inside each external feeding bin 2 for coordinated use. Each rotating material equalization device 3 corresponds to a chain and uses the same drive structure. Through the meshing and linkage of the drive gear 4, bevel gear I 41, bevel gear II 35, and driven shaft 34, the two rotating material equalization devices 3 rotate synchronously within the external feeding bin 2, achieving material release operations over a longer distance. This utility model provides a feeding channel 13 below the feeding port 12, connecting the external feeding bin 2 and the hopper 5. This structure prevents material from stagnating in the air and avoids the material failing to accurately fall into the hopper due to external airflow or other factors.

[0024] In summary, this utility model uses a chain 6 to drive several hoppers 5 to move laterally, and a rotating material distribution device 3 to rotate in conjunction. When the hoppers reach below the feeding port 12, the material in each isolated material distribution area 33 is released into the hopper through the feeding port 12 to form a quantitative feeding. During this process, the material passes through the feeding port 12 and corresponds to the feeding channel 13 on the feeding port 12. The cone plate 32 rotates to continuously block and cover the gap between adjacent hoppers, ensuring that the material enters the hopper without leaking at the gap between adjacent hoppers and achieving quantitative feeding synchronously with the operation of the hoppers.

[0025] This material conveying machinery quantitative feeding device can not only prevent material leakage, but also achieve precise quantitative supply. The invention has a simple structure and is easy to use. It overcomes the technical drawbacks of the prior art. It can be applied to Z-type elevators and C-type elevators. It is an ideal synchronous quantitative feeding device for solid materials in the hopper of a Z-type elevator.
