Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, specifically to a feeding mechanism for cleaning potatoes. Background Technology
[0002] In the potato processing industry, raw material pretreatment is a crucial step affecting product quality and production efficiency. Traditional potato cleaning processes typically remove surface dirt and sand through direct washing or mechanical friction, but these methods have the following technical drawbacks:
[0003] 1. Potatoes carry a large amount of mud and sand after harvesting from the field. When these potatoes are directly fed into the cleaning equipment, the mud and sand mix with the potatoes and enter the washing system, resulting in excessively high mud and sand content in the washing wastewater. Frequent discharge of mud and sand waste not only increases water consumption but also requires shutdowns for equipment cleaning, severely impacting production continuity.
[0004] 2. In traditional processes, potatoes are typically sorted by size, shape, or disease spots after cleaning. Unsorted potatoes may suffer skin damage due to collisions during washing, and overly small potatoes and rotten tubers reduce the efficiency of the washing equipment and increase subsequent processing costs.
[0005] 3. Direct entry of mud and sand into the cleaning mechanism will accelerate the wear of components such as drums and nozzles, and at the same time require a higher intensity of water flow or mechanical force to maintain the cleaning effect, resulting in a significant increase in energy consumption. Utility Model Content
[0006] In order to solve the technical problems existing in the prior art, this application provides a feeding mechanism for cleaning potatoes.
[0007] To achieve the above objectives, the technical solution adopted in this application is as follows: a potato cleaning feeding mechanism, comprising: a support frame; a pre-storage tank, which is disposed on the support frame and includes a storage section and a feeding section connected to the storage section; a pre-cleaning mechanism, which includes a liquid delivery pipe, a spray pipe, and a delivery pump for conveying cleaning liquid, wherein the spray pipe is disposed in the pre-storage tank and located within the storage section, the liquid delivery pipe is disposed on the pre-storage tank and connected to the spray pipe, and the delivery pump is connected to the liquid delivery pipe; and a feeding mechanism, which includes a conveyor belt and a sorting element disposed on the conveyor belt, wherein the conveyor belt is disposed in the pre-storage tank and located within the feeding section, and the sorting element is disposed on the conveyor belt for initial screening of potatoes to be fed.
[0008] In some embodiments of this utility model, the sorting element includes a base and sorting columns evenly spaced on the base, with a sorting gap formed between the two sorting columns.
[0009] In some embodiments of this utility model, an adjustment hole for adjusting the size of the sorting gap is provided between the two sorting columns, and the adjustment hole is used to insert the sorting column.
[0010] In some embodiments of this utility model, an anti-detachment head is provided at the end of any sorting column away from the base.
[0011] In some embodiments of this utility model, the anti-detachment head and the sorting column are integrally formed.
[0012] In some embodiments of this utility model, a storage plate is provided at the bottom of the storage section, the storage plate has several openings for the sorting column to pass through, and the storage plate also has through holes.
[0013] In some embodiments of this utility model, the pre-storage slot is provided with a feeding hopper, which is connected to the storage section.
[0014] In some embodiments of this utility model, a sewage discharge pipe is provided on the feeding part, which is used to discharge the mud and sand deposited in the pre-storage tank.
[0015] In some embodiments of this utility model, the above-mentioned feeding section is provided with an overflow pipe, which is connected to the pre-storage tank. Beneficial effects
[0016] 1. The potato surface is pre-wetted through spray pipes in the storage section, and the water flow impacts and removes adhering mud and sand, preventing the potatoes from carrying a large amount of mud and sand when they directly enter the cleaning system. Pre-cleaning reduces the load on subsequent cleaning, reduces the amount of mud and sand wastewater generated, and extends the continuous operation time of the equipment. After most of the mud and sand is removed in the pre-cleaning stage, the risk of wear on subsequent cleaning equipment is reduced, and the water flow intensity or mechanical force required for cleaning can be reduced, thereby reducing energy consumption.
[0017] 2. The sorting element can perform preliminary screening based on size in real time during potato conveying. Pre-sorting removes inferior raw materials, avoids ineffective washing, and improves overall processing efficiency. Attached Figure Description

[0031] Please refer to Figures 1-5 This embodiment provides a potato cleaning feeding mechanism, including: a support frame 1; a pre-storage tank 2, which is disposed on the support frame 1 and includes a storage section 201 and a feeding section 202 connected to the storage section 201; a pre-cleaning mechanism, which includes a liquid delivery pipe 3, a spray pipe, and a delivery pump 5 for delivering cleaning liquid. The spray pipe is disposed in the pre-storage tank 2 and is located in the storage section 201. The liquid delivery pipe 3 is disposed on the pre-storage tank 2 and is connected to the spray pipe. The delivery pump 5 is connected to the liquid delivery pipe 3; and a feeding mechanism, which includes a conveyor belt 6 and a sorting element disposed on the conveyor belt 6. The conveyor belt 6 is disposed in the pre-storage tank 2 and is located in the feeding section 202. The sorting element is disposed on the conveyor belt 6 and is used for initial screening of potatoes to be fed.
[0032] In this embodiment, the support frame 1 is made of high-strength alloy material and designed as a frame structure with adjustable feet or shock-absorbing pads at the bottom. It provides stable support for the pre-storage tank 2, the pre-cleaning mechanism, and the feeding mechanism, preventing the equipment from tilting due to vibration or uneven potato weight distribution, thus ensuring safe continuous operation.
[0033] In this embodiment, the aforementioned pre-storage tank 2 is an integrated tank structure, divided into a storage section 201 and a loading section 202. Located at the front end of the pre-storage tank 2, it is used for batch temporary storage of potatoes to be processed. A sedimentation zone is provided at its bottom, allowing the stripped sediment to settle naturally under gravity. Connected to the storage section 201, it contains a built-in conveyor belt 6, which guides the potatoes from the storage section 201 to the surface of the conveyor belt 6 via a ramp structure, achieving continuous transport of cleaned potatoes. The storage section 201 serves as a pre-cleaning buffer area, allowing for batch processing of potatoes and reducing the frequency of loading. The sedimentation zone collects sediment, preventing it from entering subsequent processes with the potatoes and reducing wastewater treatment pressure.
[0034] In this embodiment, the aforementioned delivery pump 5 is used to draw the cleaning liquid from the storage tank to the delivery pipe 3. The delivery pipe 3 is laid along the outer wall of the pre-storage tank 2. The delivery pump 5 increases the liquid pressure to ensure that the cleaning liquid is delivered to the spray pipe at a constant pressure. The spray pipe is embedded at the bottom of the storage section 201, and its surface is evenly distributed with multi-angle atomizing nozzles. High-pressure water jets impact the surface of the potatoes, peeling off adhering mud and sand. Pre-cleaning can effectively reduce the amount of mud and sand entering the conveyor belt 6 and sorting elements, and reduce mechanical wear.
[0035] In this embodiment, the conveyor belt 6 is used to provide a power source for driving the sorting element. The conveyor belt 6 drives the sorting element by rotating, and after selecting the potatoes temporarily stored in the storage section 201, it is transported to the cleaning equipment for in-depth cleaning.
[0036] Please refer to Figure 1 In some embodiments of this example, the sorting element includes a base 7 and sorting columns 8 evenly spaced on the base 7, with a sorting gap formed between the two sorting columns 8.
[0037] In this embodiment, the aforementioned supporting body of the sorting element is made of lightweight alloy and is fixed to the conveyor belt 6 by bolts or snap-fit structures. It supports the sorting columns 8 and maintains the stability of the sorting gap. The sorting columns 8 are cylindrical structures made of food-grade elastic material. Their surfaces are polished to reduce friction with the potatoes. The sorting columns 8 are arranged at uniform intervals on the base 7, forming a sorting gap between adjacent columns. Potatoes with a diameter smaller than the sorting gap fall through the gap, achieving initial screening.
[0038] Please refer to Figure 1In some embodiments of this example, an adjustment hole 9 is provided between the two sorting columns 8 for adjusting the size of the sorting gap, and the adjustment hole 9 is used to insert the sorting column 8.
[0039] In this embodiment, the adjustment holes 9 provided between the sorting columns 8 can be inserted into the sorting columns 8 according to different sorting requirements and sorting grades. After the sorting columns 8 are inserted, the sorting gap will be reduced, thereby improving the sorting grade.
[0040] Please refer to Figure 1 In some embodiments of this example, an anti-detachment head 10 is provided at the end of any sorting column 8 away from the base 7.
[0041] In this embodiment, the conveyor belt 6 is inclined in the pre-storage slot 2. When the drive belt drives the sorting element to rise, it will vibrate, causing the potatoes to fall off. The sorting column 8 is vertically installed on the base 7. The anti-fall head 10 is inclined towards the drive belt to prevent the potatoes from falling off due to vibration and improve the sorting efficiency.
[0042] Please refer to Figure 1 In some embodiments of this example, the anti-detachment head 10 and the sorting column 8 are integrally formed.
[0043] In this embodiment, the one-piece molding eliminates the assembly, welding, or gluing processes for the sorting column 8 and the anti-detachment head 10, shortening the production cycle and reducing labor costs. The straight rod bending process achieves near-net-shape forming, with a lower material waste rate than traditional machining, aligning with green manufacturing trends. Modular production ensures consistent bending curvature, anti-detachment head 10 dimensions, and elastic modulus for each sorting column 8, improving the quality stability of batch products.
[0044] Please refer to Figure 5 In some embodiments of this example, the bottom of the storage section 201 is provided with a storage plate 11, the storage plate 11 has a plurality of openings 12 for the sorting column 8 to pass through, and the storage plate 11 also has through holes 13.
[0045] In this embodiment, the storage plate 11 is used to hold the potatoes to be sorted. The potatoes entering the pre-storage tank 2 are piled on the storage plate 11. The conveyor belt 6 drives the sorting element to continuously pick up materials on the storage plate 11, lifting and conveying the picked-up potato raw materials to the inside of the cleaning equipment. The storage plate 11 is used for passing cleaning liquid from bottom to top and for passing deposited mud and sand from top to bottom.
[0046] Please refer to Figure 1 and Figure 5 In some embodiments of this example, the pre-storage tank 2 is provided with a feeding hopper 14, which is connected to the storage section 201.
[0047] In this embodiment, the feed hopper 14 is used to guide the potato raw material to be cleaned. The feed hopper 14 is set on the side wall of the pre-storage tank 2 and enters the pre-storage tank 2 through the side wall. In actual use, the cleaning liquid is delivered from bottom to top through the pre-cleaning mechanism. The cleaning liquid acts in the opposite direction to the gravity of the potato, so as to avoid damage to the potato skin caused by collision between potatoes.
[0048] Please refer to Figure 4 and Figure 5 In some embodiments of this example, the feeding section 202 is provided with a sewage pipe 15, which is used to discharge the mud and sand deposited in the pre-storage tank 2.
[0049] In this embodiment, the inlet of the sewage pipe 15 is located at the lowest point of the feeding section 202. Taking advantage of the fact that the density of mud and sand is greater than that of water, the mud and sand are naturally deposited to the pipe inlet by gravity. The high-pressure water flow of the spray pipe washes the mud and sand on the surface of the potatoes to the storage section 201. The fine mud and sand that are not filtered by the gaps of the sorting column 8 enter the feeding section 202 with the water flow and are finally discharged through the sewage pipe 15.
[0050] Please refer to Figure 4 and Figure 5 In some embodiments of this example, the feeding section 202 is provided with an overflow pipe 16, which is connected to the pre-storage tank 2.
[0051] In this embodiment, the above-mentioned pipe inlet is set at a preset height on the side wall of the feeding section 202. When the water level rises to the threshold due to the spray cleaning of the storage section 201, the excess water is automatically discharged into the overflow pipe 16 through the overflow port to facilitate water circulation.
[0052] In use, the pre-cleaning mechanism's delivery pump 5 is turned on, and high-pressure cleaning fluid is introduced into the liquid delivery pipe 3. The cleaning fluid enters the pre-storage tank 2 through the spray pipe and is slowly injected from bottom to top into the pre-storage tank 2. When the cleaning fluid level reaches the overflow pipe 16, it flows out. Then, the potatoes to be cleaned are conveyed into the pre-storage tank 2 through the feed hopper 14. The potatoes enter the water-filled pre-storage tank 2, and the overflowing cleaning fluid washes away the mud and sand on the surface of the potatoes. The mud and sand flow down the inclined bottom plate of the feeding section 202. When the sediment accumulates to a threshold at the opening of the sewage pipe 15, the valve on the sewage pipe 15 (not shown in the figure) is opened to discharge the sediment. When the potatoes to be cleaned are poured in, the conveyor belt 6 is driven to rotate synchronously. The sorting element on the rotating conveyor belt 6 continuously sweeps across the opening 12 of the storage plate 11, sorting and lifting the potatoes on the storage plate 11. Potatoes with a diameter smaller than the sorting gap automatically fall back into the pre-storage tank 2. Potatoes of suitable diameter that are selected can enter the cleaning equipment for deep cleaning.
[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
