Description

Technical Field

[0001] This utility model belongs to the technical field of product finishing equipment, and specifically relates to an agricultural water chestnut sorting device. Background Technology

[0002] The bulk distribution of water chestnuts is concentrated in the first transaction between cooperatives and farmers. In most cases, the price of the first transaction is based on the raw fruit after primary sorting. Therefore, the shape and size of water chestnuts directly affect their overall quality and price. Sorting out water chestnuts that meet the shape and size requirements has direct economic benefits. The primary sorting of water chestnuts is the most labor-intensive production link in the initial processing of this product.

[0003] In the upstream supply chain of this product, the acquisition and initial processing stages currently rely mainly on manual screening, inspection, and weighing to identify substandard varieties before completing the acquisition transaction. This manual sorting of agricultural products is a tedious and laborious task susceptible to human error. Manual selection is not only inefficient but also prone to errors due to subjective factors, resulting in inconsistent quality and uneven distribution of water chestnuts. Furthermore, the large volume and fast pace of transactions in the acquisition and initial processing stages lead to high labor intensity and long processing times, indirectly resulting in high labor costs and impacting the profitability of the finished product.

[0036] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0037] An agricultural water chestnut sorting device, referring to Figure 1 The system includes a feeding system 1, a soil removal and sorting system, and a weighing system 4, which are arranged in sequence. The feeding system 1 is used to centrally feed bulk water chestnuts. The soil removal and sorting system includes a soil removal module 2 and a screening module 3. The soil removal module 2 is used to remove the soil from the surface of the water chestnuts, and the screening module 3 is used to screen water chestnuts of different sizes. The weighing system 4 is used to quickly weigh the screened water chestnuts.

[0038] Reference Figure 2 The feeding system 1 includes a support frame 11 and a conveyor belt 12 fixed on the support frame 11. A feed plate 13 and a discharge plate 14 are respectively installed at both ends of the conveyor belt 12. The feed plate 13 is horizontally arranged, and the discharge plate 14 is inclined downwards and located above the soil removal module 2. The bulk water chestnuts to be sorted are lifted from the feed plate 13 to the discharge plate 14 via the conveyor belt 12, and then slide down the discharge plate 14 to the feeding position of the soil removal module 2 for further processing. Scrapers 15 are evenly spaced on the conveyor belt 12, which allow the water chestnuts to be smoothly lifted to the discharge plate 14.

[0039] Reference Figure 3 and Figure 4The soil removal module 2 includes a fixed frame 21, on which a roller shaft 23 is mounted. Bearing seats are installed on both sides of the fixed frame 21, and both ends of the roller shaft 23 are connected to the bearing seats. The soil removal module 2 also includes a reduction motor for driving the roller shaft 23 to rotate. A peeling roller 22 is fixedly fitted onto the roller shaft 23. Both ends of the peeling roller 22 are open, and the discharge port of the discharge plate 14 extends into the peeling roller 22, thereby stably conveying the water chestnuts into the peeling roller 22.

[0040] Reference Figure 3 and Figure 4 The peeling roller 22 includes mounting plates 221 at both ends, with a plurality of peeling rods 222 circumferentially spaced between the two mounting plates 221. The distance between two adjacent peeling rods 222 is less than the volume of the water chestnut. Additionally, the peeling roller 22 is surrounded by an outer shell 24, which includes a soil discharge port 241 located below the peeling roller 22. Water chestnuts enter the peeling roller 22 through the discharge plate 14. Driven by a reduction motor, the peeling roller 22 rotates at a constant speed. Due to centrifugal force, the water chestnuts rub against the peeling rods 222, causing the soil to separate from the surface of the water chestnuts. The separated soil is discharged through the soil discharge port 241. The peeling roller 22 is arranged at a certain angle, and the water chestnuts, after being peeled by the soil, are discharged from the discharge end of the peeling roller 22 under their own weight, entering the next process.

[0041] Additionally, refer to Figure 3 and Figure 4 The fixed frame 21 is also fixed with a discharge baffle 25. The discharge baffle 25 is set parallel to the end face of the discharge end of the peeling roller 22 and the discharge end of the peeling roller 22 is located above the screening module 3. By setting the discharge baffle 25 to limit the drop point and movement trajectory of the water chestnuts, the water chestnuts can be discharged to the screening module 3 more accurately.

[0042] Reference Figure 5 and Figure 6 The screening module 3 includes an outer shell 33, inside which a screening screen 31 and a chain drive system for driving the screening screen 31 to move are provided; the screening screen 31 is woven from steel wire and is a flexible screen with a diamond-shaped screening grid.

[0043] Reference Figure 6 The chain drive system includes a drive motor, two coaxially mounted drive sprockets 323, six idler pulleys 321, and two lug chains 322. Each lug chain 322 simultaneously meshes with three idler pulleys 321 and one drive sprocket 323, and the rotation of the drive sprockets 323 drives the lug chains 322 to rotate. The two sides of the screening screen 31 are respectively installed and connected to the lug chains 322. A sprocket tensioning seat is provided on the idler pulley 321 on the non-drive side for adjusting the chain tension.

[0044] Reference Figure 5 and Figure 6 The outer casing 33 includes a defective product outlet 331 located below the screening screen 31 and a weighing outlet 36 for discharging qualified water chestnuts into the weighing system 4. A discharge roller 34 for transporting the screened water chestnuts out is located near the weighing outlet 36 on the screening screen 31. Defective water chestnuts that are screened out are discharged through the defective product outlet 331, while qualified water chestnuts are transported to the next process through the weighing outlet 36. The discharge roller 34 is disposed inside the screening screen 31 and located above the weighing system 4, with the surface of the discharge roller 34 in contact with the screening screen 31. The contact between the surface of the discharge roller 34 and the screening screen 31 is to prevent water chestnuts from getting stuck in the mesh of the screening screen 31. As the screening screen 31 is brought into the bottom of the screening module 3, the discharge roller 34 can squeeze the water chestnuts stuck in the mesh above the discharge port.

[0045] Furthermore, refer to Figure 5 The outer casing 33 includes an upper cover plate 332 located above the screening screen 31. Baffles 35 are fixed to the outer casing 33, spaced apart above the screening screen 31 and positioned close to the discharge roller 34. The area enclosed between the baffles 35 and the upper cover plate 332 is the screening zone 333, which is the effective sorting area for water chestnuts. The upper cover plate 332 and baffles 35 are used to limit the sorting of water chestnuts to the area above the defective product discharge port 331, preventing defective products from falling outside the defective product discharge port 331.

[0046] It should be noted that the bottom of the baffle 35 is designed with a pressing surface, which enables the baffle 35 to achieve the following functions: First, when the screening screen 31 moves, it provides a pressing force to ensure that the water chestnuts are in close contact with the screening screen 31, thereby improving the sorting quality; Second, it prevents some unscreened water chestnuts from being discharged directly from the weighing outlet 36 due to material accumulation; Third, when the water chestnuts are intermittently pressed against the screening screen 31, they impact the screening screen 31, providing vibration and improving the screening effect.

[0047] Reference Figure 7 The weighing system 4 includes a base frame 41, on which a weight sensor 42 and a roller conveyor 43 are installed. A receiving frame 44 for loading water chestnuts is placed on the roller conveyor 43. After sorting, the water chestnuts fall into the receiving frame 44 from the weighing outlet 36. The weighing system 4 peels and weighs the water chestnuts in the frame and then transports them horizontally to the transport vehicle via the roller conveyor 43.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
