Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and in particular to an automated conveying equipment for agricultural products. Background Technology

[0002] In existing technologies, agricultural products (such as potatoes) are often transported and transferred via conveyor belts. However, existing conveyor belts have the following problems: agricultural products often fall directly onto the conveyor belt from a height. Both the impact force between the agricultural products and the conveyor belt, as well as the impact force between the agricultural products themselves, can easily cause damage to the agricultural products. Summary of the Invention

[0003] To overcome the drawback of agricultural products being easily damaged by impact, this invention provides an automated agricultural product conveying device, comprising a buffer box, a return box, and a conveyor belt. The return box is fixedly connected to the right side of the buffer box, and the buffer box and the return box are spatially interconnected. A conveyor belt is installed in both the buffer box and the return box, and the conveyor belt is inclined from the lower left to the upper right. The left end of the conveyor belt is located within the buffer box area. Buffer particles are added to the buffer box. When agricultural products fall downwards into the buffer box, the buffer particles cushion the agricultural products, and the buffer particles are returned to the buffer box via the return box.

[0004] In one embodiment, the conveyor belt is configured as a double-layer structure, including a rotating roller, an inner conveyor belt, connecting plates, a baffle assembly, and an outer conveyor belt assembly. A rotating roller is installed on the right side of the buffer box, and another rotating roller is installed on the right side of the return box. The inner conveyor belt is mounted on both rotating rollers. Several connecting plates are fixed to the outer ring surface of the inner conveyor belt. Baffle assemblies are fixed to the connecting plates. The inner conveyor belt is connected to the outer conveyor belt assembly through the connecting plates. When the conveyor belt is running, the agricultural products are moved by the baffle assembly, the agricultural products are received by the outer conveyor belt assembly, and the particles are filtered and buffered through the baffle assembly and the outer conveyor belt assembly.

[0005] In one embodiment, the baffle assembly consists of a plurality of equally spaced baffles; the outer conveyor belt assembly consists of a plurality of equally spaced conveyor belts.

[0006] In one embodiment, protective side plates for shielding and protecting the rotating rollers are provided on both the front and rear sides of the conveyor belt.

[0007] In one embodiment, a receiving partition plate is provided in the buffer box to divide the buffer box into upper and lower parts. A blocking component is fixed to the right side of the receiving partition plate. The blocking component consists of multiple equally spaced blocking strips. The blocking component prevents agricultural products from falling down to the lower half of the buffer box. When the baffle assembly moves through the area where the blocking component is located, the baffle of the baffle assembly and the blocking strips of the blocking component pass through each other without interfering with each other.

[0008] In one embodiment, a feeding pipe assembly for feeding buffer particles into the upper half of the buffer box is installed in the upper left part of the buffer box.

[0009] In one embodiment, a suction assembly for transferring buffer particles in the lower left region of the buffer box is installed in the lower left part of the buffer box.

[0010] In one embodiment, a cleaning device is also included, wherein a suction assembly transfers the buffer particles in the lower half of the buffer box to the cleaning device for cleaning, and a feeding pipe assembly feeds the cleaned buffer particles into the upper half of the buffer box.

[0011] In one embodiment, a transfer housing is also included. The transfer housing is disposed on the rear side of the return box and protrudes outward from the return box, allowing the buffer particles located in the upper region of the inner conveyor belt to be transferred to the lower region of the inner conveyor belt through the transfer housing.

[0012] In one embodiment, the rotating roller is configured to be larger at the front and smaller at the back, and the inner conveyor belt is configured to be larger at the front and smaller at the back.

[0013] Compared with the prior art, the present invention has the following advantages: The present invention uses food-grade rubber or silicone buffer particles as buffer particles, which solves the problem of rigid impact and mutual collision damage caused by agricultural products falling from heights in traditional conveyor belts. The buffer particles can form a flexible support and protection for agricultural products. At the same time, with their small volume, they can fully wrap agricultural products of different shapes. During the buffering and conveying process, they can efficiently adhere to and remove a large amount of dirt from the surface of agricultural products, greatly reducing the amount of subsequent cleaning work.

[0014] In the conveying operation, this invention utilizes the gap structure between the baffle assembly and the outer conveyor belt assembly, combined with the front-large and rear-small rotating rollers and the inner conveyor belt structure with its upper surface inclined to the rear and downward, to allow the buffer particles to separate from the agricultural products and smoothly flow back to the buffer box through the transfer shell and return box for recycling. Furthermore, during the return process, the moving baffle assembly can assist in pushing the buffer particles back, and the continuous contact and friction between the buffer particles and the baffle can also achieve self-cleaning of the baffle.

[0015] This invention uses a suction component to continuously extract dirty buffer particles for cleaning, and a feeding pipe assembly to continuously replenish clean buffer particles to the upper part of the buffer box. This ensures that the buffer particles always maintain a high level of cleanliness and also continuously forms a buffer covering layer on top of agricultural products, completely avoiding direct contact and collision between agricultural products.

Detailed Implementation

[0025] 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 is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0026] Example 1: As Figures 1-8 As shown, an automated agricultural product conveying device includes a buffer box 1, a return box 2, and a conveyor belt 3. The return box 2 is fixedly connected to the right side of the buffer box 1, and the buffer box 1 and the return box 2 are spatially connected. The return box 2 is inclined from the lower left to the upper right. The conveyor belt 3 is installed in the buffer box 1 and the return box 2, and the conveyor belt 3 is inclined from the lower left to the upper right. The left end of the conveyor belt 3 is located in the area of ​​the buffer box 1. Buffer particles are added to the buffer box 1. When agricultural products fall into the buffer box 1, the buffer particles in the buffer box 1 buffer the agricultural products, and the buffer particles are returned to the buffer box 1 through the return box 2.

[0027] The buffer particles are added at a depth equal to the standard filling depth of 1a.

[0028] The conveyor belt 3 is configured with a double-layer structure, including a rotating roller 31, an inner conveyor belt 32, connecting plates 33, a baffle assembly 34, and an outer conveyor belt assembly 35. A rotating roller 31 is installed on the right side of the buffer box 1, and another rotating roller 31 is installed on the right side of the return box 2. The inner conveyor belt 32 is installed on the two rotating rollers 31. Several connecting plates 33 are fixedly connected to the outer ring surface of the inner conveyor belt 32. A baffle assembly 34 is fixedly connected to one half of the connecting plates 33. The inner conveyor belt 32 is connected to the outer conveyor belt assembly 35 through the connecting plates 33. When the conveyor belt 3 is running, the agricultural products are moved by the baffle assembly 34, the agricultural products are received by the outer conveyor belt assembly 35, and the particles are filtered and buffered through the baffle assembly 34 and the outer conveyor belt assembly 35.

[0029] The baffle assembly 34 consists of multiple baffles that are evenly distributed; the outer conveyor belt assembly 35 consists of multiple conveyor belts that are evenly distributed.

[0030] The conveyor belt 3 is equipped with protective side plates 36 on both the front and rear sides to shield and protect the rotating roller 31.

[0031] The buffer box 1 is equipped with a receiving partition plate 11, which divides the buffer box 1 into upper and lower parts. A blocking component 12 is fixed to the right side of the receiving partition plate 11. The blocking component 12 consists of multiple equally spaced blocking strips, which prevent agricultural products from falling downwards into the lower half of the buffer box 1. Figure 4 As shown, when the baffle assembly 34 moves through the area where the blocking assembly 12 is located, the baffle of the baffle assembly 34 and the blocking strip of the blocking assembly 12 pass through each other without interfering with each other.

[0032] A feeding pipe assembly 101 for feeding buffer particles into the upper half of the buffer box 1 is installed in the upper left part of the buffer box 1.

[0033] A suction assembly 102 for transferring buffer particles in the lower half of the buffer box 1 is installed in the lower left part of the buffer box 1.

[0034] It also includes a cleaning device (not shown in the figure), the suction assembly 102 transfers the buffer particles in the lower half of the buffer box 1 to the cleaning device for cleaning, and the feeding pipe assembly 101 sends the cleaned buffer particles into the upper half of the buffer box 1.

[0035] It also includes a transfer housing 21. The transfer housing 21 is provided on the rear side of the return box 2. The transfer housing 21 protrudes outward from the return box 2, so that the buffer particles located in the upper area of ​​the inner conveyor belt 32 can be transferred to the lower area of ​​the inner conveyor belt 32 through the transfer housing 21.

[0036] like Figures 6-7As shown, the rotating roller 31 is configured to be larger at the front and smaller at the back, and the inner conveyor belt 32 is also configured to be larger at the front and smaller at the back, so that the upper surface of the inner conveyor belt 32 is inclined to the rear and downward, which facilitates the transfer of buffered particles into the transfer housing 21. The rotating roller 31 and the inner conveyor belt 32 can be driven by meshing teeth and tooth holes to prevent slippage.

[0037] In existing technologies, agricultural products (such as potatoes) are often transported and transferred via conveyor belts. However, existing conveyor belts have the following problems: agricultural products often fall directly onto the conveyor belt from a height. Both the impact force between the agricultural products and the conveyor belt, as well as the impact force between the agricultural products themselves, can easily cause damage to the agricultural products.

[0038] To address this issue, the present invention is proposed. When the present invention operates, as follows: Figure 1 As shown, buffer particles are added to the buffer box 1 through the feeding pipe assembly 101 until the standard filling depth 1a is reached. When the agricultural products fall downwards, the buffer particles in the buffer box 1 buffer the agricultural products to avoid collision between the agricultural products and the conveyor belt 3.

[0039] The cushioning particles can be food-grade rubber particles or food-grade silicone particles, and have the characteristics of being anti-collision, reusable, non-scattering, and safe for food contact.

[0040] like Figure 3 As shown, the agricultural products falling into the buffer box 1 are received by the receiving partition plate 11 and mixed with the buffer particles. When the conveyor belt 3 is running, the rotating roller 31 drives the inner conveyor belt 32, the connecting plate 33, the baffle assembly 34 and the outer conveyor belt assembly 35 to rotate. The baffle assembly 34 carries away the agricultural products in the buffer box 1 and drives the agricultural products to move to the right. During the movement of the agricultural products, the outer conveyor belt assembly 35 receives the agricultural products.

[0041] The baffle assembly 34 consists of multiple equally spaced baffles, and the outer conveyor belt assembly 35 consists of multiple equally spaced conveyor belts. Therefore, during the transfer of agricultural products to the right, the buffer particles mixed with the agricultural products fall through the gaps between the baffles and the gaps between the conveyor belts into the upper area of ​​the inner conveyor belt 32, and are then transferred to the transfer housing 21. Furthermore, by setting the rotating roller 31 to be larger at the front and smaller at the back, and the inner conveyor belt 32 to be larger at the front and smaller at the back, the upper surface of the inner conveyor belt 32 is inclined downwards and backwards, allowing the buffer particles to be easily transferred into the transfer housing 21. Figure 8 As shown, the buffer particles that enter the transfer housing 21 are transferred from the upper region of the inner conveyor belt 32 to the lower region of the inner conveyor belt 32, and then transferred back to the buffer housing 1 through the return box 2.

[0042] It should be noted that because agricultural products (such as potatoes) often have soil on their surface, during transportation, the soil on the surface of the agricultural products will be adhered to and carried away by the buffer particles. Since the buffer particles are small in size, they can fully wrap agricultural products of different shapes, thus removing most of the soil from the surface of the agricultural products and reducing the amount of work required to clean the soil from the agricultural products later.

[0043] Furthermore, such as Figure 8 As shown, when the buffer particles are transferred through the transfer housing 21 to the lower region of the inner conveyor belt 32, Figure 8 From the perspective, the baffle assembly 34 located below moves to the right. The baffle assembly 34 moving to the right can help push the buffer particles to the lower half of the buffer box 1. At the same time, the baffle of the baffle assembly 34 will also continuously contact different buffer particles. In this way, the buffer particles can be used to scrape the baffle to remove the dirt adhering to the baffle, thus achieving self-cleaning.

[0044] Furthermore, by setting up the suction component 102, the buffer particles mixed with soil in the buffer box 1 can be continuously transferred to the cleaning equipment for cleaning, so that the buffer particles can be recycled, ensuring the cleanliness of the buffer particles and improving the ability of the buffer particles to continuously remove soil from the surface of agricultural products.

[0045] Furthermore, clean buffer particles are continuously fed into the upper part of the buffer box 1 through the feeding pipe assembly 101. On the one hand, this ensures that the agricultural products transferred to the buffer box 1 are in continuous contact with the clean buffer particles. On the other hand, by continuously feeding in buffer particles, buffer particles are placed on top of the agricultural products that have been transferred to the buffer box 1, ensuring that the agricultural products transferred to the buffer box 1 are buffered by the buffer particles and do not directly contact or collide with the agricultural products that were previously fed into the buffer box 1.

[0046] In summary, this invention uses food-grade rubber or silicone buffer particles as buffer particles, which solves the problem of rigid impact and mutual collision damage caused by agricultural products falling from heights in traditional conveyor belts. The buffer particles can provide flexible support and protection for agricultural products. At the same time, due to their small volume, they can fully wrap agricultural products of different shapes. During the buffering and conveying process, they can efficiently adhere to and remove a large amount of dirt from the surface of agricultural products, greatly reducing the amount of subsequent cleaning work.

[0047] In the conveying operation, the present invention utilizes the gap structure between the baffle assembly 34 and the outer conveyor belt assembly 35, combined with the front-large and rear-small rotating roller 31 and the inner conveyor belt 32 with its upper surface inclined to the rear and downward, to allow the buffer particles to be separated from the agricultural products and smoothly flow back to the buffer box 1 through the transfer shell 21 and the return box 2 for recycling; and during the return process, the moving baffle assembly 34 can assist in pushing the buffer particles back, and at the same time, the continuous contact and friction between the buffer particles and the baffle can also achieve self-cleaning of the baffle;

[0048] The present invention uses a suction component 102 to continuously extract dirty buffer particles for cleaning, and a feeding pipe assembly 101 to continuously replenish clean buffer particles to the upper part of the buffer box 1. This ensures that the buffer particles always maintain a high level of cleanliness and can continuously form a buffer covering layer on top of agricultural products, thus completely avoiding direct contact and collision between agricultural products.
