Description

Technical Field

[0001] This utility model relates to the field of jujube processing technology, specifically a multi-layer material arrangement and conveying device. Background Technology

[0002] After harvesting, jujubes typically need to be sorted according to characteristics such as size, quality, and color to ensure that each grade of jujubes meets the corresponding standards, thereby improving the overall quality of the product. Currently, jujubes are usually sorted manually, which is not only time-consuming and labor-intensive, but also inefficient. Furthermore, the manual sorting process can cause secondary damage to the jujubes.

[0003] Chinese invention patent publication CN110530290A discloses a jujube sorting device, including a feeding hopper, a feeding and lifting machine, an arranging mechanism, and a sorting mechanism. The feeding hopper has a first vibrating hopper at its discharge end, which connects to the receiving end of the feeding and lifting machine. A second vibrating hopper connects to the discharge end of the feeding and lifting machine. Multiple arranging mechanisms are arranged side-by-side at the discharge end of the second vibrating hopper. The arranging mechanism includes a frame and a double-row conveyor chain. The frame supports the double-row conveyor chain, which has several rollers arranged side-by-side with their axial direction perpendicular to the conveying direction of the double-row conveyor chain. Symmetrical waist drums are provided at both ends of the rollers. The gaps between adjacent waist drums on adjacent rollers are used to clamp jujubes. Protective plates fixed to the frame are symmetrically arranged on both outer sides of the double-row conveyor chain, forming a material guide channel. The sorting mechanism includes a camera recognition area, a spray valve, and a waste recycling conveyor belt. This invention has a high degree of automation, good sorting effect, and improved work efficiency.

[0004] In the above technology, the material guiding channel is set in a single layer. Although there are multiple material guiding channels, the amount of jujube material that can be distributed in a single distribution is still limited, resulting in low overall distribution efficiency. It requires a lot of recycling and re-distribution, which will cause the jujube material to fall or roll repeatedly, thus affecting the quality of the jujube product.

[0005] Therefore, it is urgent to develop a technical solution to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a multi-layer material arrangement and conveying device that can arrange materials in multiple levels simultaneously and evenly, avoiding multiple material recycling cycles; improving material arrangement speed and enhancing the overall material conveying efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution;

[0008] A multi-layer material distribution and conveying device includes a lifting unit, a material distribution unit, and a circulation unit; the lifting unit lifts the material to the inlet of the material distribution unit, and the material distribution unit includes at least one layer of uniform distribution mechanism and a bottom layer of distribution mechanism.

[0009] The material to be arranged enters the uniform distribution mechanism and the bottom layer arrangement mechanism from the material lifting unit for arrangement. The uniform distribution mechanism and the bottom layer arrangement mechanism then send the arranged material to the conveying roller group. During the arrangement process, excess material in the uniform distribution mechanism falls down step by step and finally falls into the bottom layer arrangement mechanism. Excess material in the bottom layer arrangement mechanism falls into the circulation unit. The circulation unit then transports the material that falls from the bottom layer arrangement mechanism to the material lifting unit.

[0011] Furthermore, the uniform distribution mechanism includes multiple parallel uniform distribution conveyor belts, with gaps reserved between the uniform distribution conveyor belts for material to fall through, and multiple cloth brushes provided on each uniform distribution conveyor belt;

[0012] As the uniformly distributed conveyor belt moves the material, the cloth brush flattens the stacked material or pulls it out of the gaps in the uniformly distributed conveyor belt.

[0013] Furthermore, the uniformly distributed conveyor belt is also equipped with multiple material discharge plates and material discharge guides; the material falls from the uniformly distributed conveyor belt into the gap, is diverted by the material discharge plates to the material discharge guides, and the material discharge guides the material into the next layer of uniform distribution mechanism until the material falls into the bottom layer of the distribution mechanism.

[0014] Furthermore, the bottom layer arrangement mechanism includes multiple parallel bottom layer conveyor belts, with gaps reserved between the bottom layer conveyor belts for material to fall, and multiple fabric brushes are provided on each bottom layer conveyor belt.

[0015] Furthermore, the material lifting unit includes a lifting mechanism and a conveying mechanism; the lifting mechanism lifts the material to be evenly distributed to a predetermined height and feeds the material into the feed end of the conveying mechanism; the conveying mechanism feeds the material onto the evenly distributed guide plate and the bottom guide plate.

[0016] Furthermore, the circulation unit includes a first circulation conveyor belt, a circulation elevator, and a second circulation conveyor belt; the first circulation conveyor belt is located below the bottom layer arrangement mechanism, the circulation elevator is located at the discharge end of the first circulation conveyor belt, and the second circulation conveyor belt is located at the discharge end of the circulation elevator; the second circulation conveyor belt delivers the recovered material to the lifting unit to complete the circulation.

[0017] Furthermore, the projected area of ​​the first circulating conveyor belt is larger than the projected area of ​​the bottom arrangement mechanism.

[0018] Furthermore, both the uniform distribution mechanism and the bottom layer arrangement mechanism are equipped with a material guide conveyor belt at their discharge ends, which delivers the material to the conveyor roller group.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] In practical use, the uniform distribution mechanism and the bottom layer arrangement mechanism form a multi-layer arrangement structure. The multi-layer uniform distribution mechanism and the bottom layer arrangement mechanism work together to collect the fallen materials and realize the re-arrangement of materials before recycling, avoiding multiple recycling cycles, reducing the number of cycles, and preventing materials from being damaged due to repeated collisions. The circulation unit and the lifting unit realize the automated circulation of the conveying device, improve the material arrangement speed, and improve the overall material conveying efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] refer to Figure 1-4 As shown, a multi-layer material distribution and conveying device includes a lifting unit 1, a material distribution unit 2, and a circulation unit 3; the lifting unit 1 lifts the material to the inlet of the material distribution unit 2, and the material distribution unit 2 includes at least one layer of uniform distribution mechanism 213 and a bottom layer of distribution mechanism 215.

[0027] The material to be arranged enters the uniform distribution mechanism 213 and the bottom layer arrangement mechanism 215 from the material lifting unit 1 for arrangement. The uniform distribution mechanism 213 and the bottom layer arrangement mechanism 215 send the arranged material into the conveying roller group 5. During the arrangement process, the excess material in the uniform distribution mechanism 213 falls down step by step and finally falls into the bottom layer arrangement mechanism 215. The excess material in the bottom layer arrangement mechanism 215 falls into the circulation unit 3. The circulation unit 3 conveys the material that falls from the bottom layer arrangement mechanism 215 to the material lifting unit 1.

[0028] Specifically, the uniform distribution mechanism 213 can be a multi-layer design. In this embodiment, only a single layer of uniform distribution mechanism 213 combined with the bottom layer arrangement 215 is used to illustrate the technical solution.

[0029] This multi-layer material distribution and conveying device consists of a uniform distribution mechanism 213 and a bottom layer distribution mechanism 215 forming a multi-layer distribution structure. The multi-layer uniform distribution mechanism 213 and the bottom layer distribution mechanism 215 work together to collect fallen materials, realize the re-distribution of materials before recycling, avoid multiple recycling cycles, reduce the number of cycles, and prevent materials from being damaged due to repeated collisions. The circulation unit 3 and the lifting unit 1 realize the automated circulation of the conveying device, improve the material distribution speed, and improve the overall material conveying efficiency.

[0030] In this embodiment, the feeding port of the uniform distribution mechanism 213 is provided with a uniform distribution guide plate 211, and the feeding port of the bottom layer arrangement mechanism 215 is provided with a bottom layer guide plate 212; both the uniform distribution guide plate 211 and the bottom layer guide plate 212 overlap at the discharging end of the lifting unit 1. Specifically, the uniform distribution guide plate 211 and the bottom layer guide plate 212 are arranged in layers, which can realize the diversion of materials during the feeding stage and avoid excessive accumulation of materials on the uniform distribution mechanism 213, thus affecting the material arrangement effect.

[0031] In this embodiment, the uniform distribution mechanism 213 includes multiple parallel uniform distribution conveyor belts, with gaps reserved between the uniform distribution conveyor belts for materials to fall through. Each uniform distribution conveyor belt is equipped with multiple cloth brushes 214. When the uniform distribution conveyor belts move the materials, the cloth brushes 214 flatten the stacked materials or push them out of the uniform distribution conveyor belts so that they fall through the gaps.

[0032] Specifically, the uniform distribution mechanism 213 can use an electrically driven conveyor belt assembly. The material is driven by the uniform distribution conveyor belt, and the cloth brush 214 gently brushes and moves the material, which not only moves the stacked material to make it spread out, but also pushes the excess material into the lower layer through the gaps. At the same time, it also removes the floating dust and impurities on the spread material for the first time, improves the efficiency of subsequent material processing, and avoids the mixing of other impurities.

[0033] In this embodiment, the uniformly distributed conveyor belt is also provided with multiple material dropping plates 217 and material dropping guide plates 216; the material falls from the uniformly distributed conveyor belt into the gap, and is diverted by the material dropping plates 217 to the material dropping guide plates 216. The material dropping guide plates 216 guide the material into the next layer of uniformly distributed mechanism 213 until the material falls into the bottom layer of arrangement mechanism 215.

[0034] Specifically, the material discharge plate 217 is used to divert excess material falling down to prevent it from falling down and accumulating again; the material discharge guide plate 216 can guide the material after being diverted by the material discharge plate 217 to the lower layer of the uniform distribution mechanism 213. If the uniform distribution mechanism 213 has only one layer, the material will be guided to the bottom layer of the arrangement mechanism 215.

[0035] In this embodiment, the bottom layer arrangement mechanism 215 includes multiple parallel bottom layer conveyor belts, with gaps reserved between the bottom layer conveyor belts for material to fall, and multiple fabric brushes 214 are provided on each bottom layer conveyor belt.

[0036] Specifically, the bottom conveyor belt in the bottom arrangement mechanism 215 can be an electrically driven conveyor belt assembly. The cloth brush 214 on the bottom conveyor belt gently brushes and moves the material, making the stacked material flat, or pushing the excess material into the circulation unit 3 through the gap.

[0037] In this embodiment, the material lifting unit 1 includes a lifting mechanism 11 and a conveying mechanism 12; the lifting mechanism 11 lifts the material to be evenly distributed to a predetermined height and sends the material into the feed end of the conveying mechanism 12; the conveying mechanism 12 sends the material to the evenly distributed guide plate 211 and the bottom guide plate 212.

[0038] Specifically, the lifting mechanism 1 can be an electrically driven feeding elevator, and the conveying mechanism 12 can be an electrically driven conveyor belt assembly. The lifting mechanism 1 and the conveying mechanism 12 work together to automatically lift the material. The conveying mechanism 12 performs parallel transportation in a certain form to pre-sort the material and avoid accumulation to a certain extent. Then, the material is evenly delivered to the uniform distribution guide plate 211 and the bottom guide plate 212 so that the material enters the uniform distribution mechanism 213 and the bottom arrangement mechanism 215.

[0039] In this embodiment, the circulation unit 3 includes a first circulation conveyor belt 31, a circulation elevator 32, and a second circulation conveyor belt 33. The first circulation conveyor belt 31 is located below the bottom arrangement mechanism 215, the circulation elevator 32 is located at the discharge end of the first circulation conveyor belt 31, and the second circulation conveyor belt 33 is located at the discharge end of the circulation elevator 32. The second circulation conveyor belt 33 delivers the recovered material to the lifting unit 1 to complete the circulation.

[0040] Specifically, the first conveyor belt 31 can be an electrically driven conveyor belt assembly, the circulating elevator 32 can be a combination of a conveyor belt and an elevator, and the circulating second conveyor belt 33 can be an electrically driven conveyor belt assembly. The circulating first conveyor belt 31 collects and transports the fallen materials so that the materials enter the circulating elevator 32. The circulating elevator 32 automatically transports and lifts the recovered materials onto the circulating second conveyor belt 33, which then sends the materials to the material lifting unit 1 to complete the recycling process and improve the overall recycling efficiency.

[0041] In this embodiment, the projected area of ​​the first circulating conveyor belt 31 is greater than the projected area of ​​the bottom arrangement mechanism 215.

[0042] Specifically, the actual conveying area of ​​the first circulating conveyor belt 31 is greater than that of the bottom arrangement mechanism 215, ensuring that materials falling from any position on the bottom arrangement mechanism 215 can fall onto the first circulating conveyor belt 31, improving circulation efficiency and preventing materials from accumulating in one place and falling in a concentrated manner.

[0043] In this embodiment, both the uniform distribution mechanism and the bottom layer arrangement mechanism are equipped with a material guide conveyor belt 22 at their discharge ends, which delivers the material to the conveyor roller group.

[0044] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the scope defined by the spirit of this utility model.
