Description

Technical Field

[0001] This utility model relates to the field of primary agricultural product processing technology, and in particular to a screening device for primary agricultural product processing. Background Technology

[0002] Primary agricultural product processing refers to the preliminary screening, grading, and cleaning of crops, livestock and poultry products to meet market circulation or deep processing needs. Screening is a key process in primary agricultural product processing, and its efficiency directly affects product quality and subsequent processing costs.

[0003] Traditional primary agricultural product screening devices (such as screening equipment for peanuts, grains, etc.) usually use manual or mechanical dumping to directly pour materials into the screen frame, resulting in agricultural products accumulating on the surface of the screen frame. Some materials slide down the inclined surface of the screen frame before being screened, mixing with impurities and being discharged, causing problems such as incomplete screening and low purity of the finished product. In order to solve the above problems, we have proposed this screening device for primary agricultural product processing. Utility Model Content

[0004] The main objective of this invention is to provide a screening device for primary agricultural product processing, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A screening device for primary agricultural product processing includes a screening box, two doors, two screening frames, and a controller. Multiple mounting blocks are fixedly connected to the inner walls of both sides of the screening box. Two connecting blocks are fixedly connected to the side walls of each screening frame. The mounting blocks are connected to the lower ends of adjacent connecting blocks via shock absorbers. The screening box is equipped with a material guiding mechanism for introducing agricultural products. The material guiding mechanism includes a rotating cylinder fixedly connected to the screening box, a feeding hopper connected to the rotating cylinder, a drive motor fixedly connected to the upper end of the rotating cylinder, a rotating disk fixedly connected to the output shaft of the drive motor, multiple material discharge holes at the upper end of the rotating disk, and a material guide port at the lower end of the rotating cylinder. Vibration motors are installed on the side walls of both screening frames. One screening frame contains a first screen plate. Two receiving frames are fixedly connected to the side wall of the screening box. A filtering mechanism for filtering agricultural products is installed in the other screening frame.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-6 As shown, a screening device for primary agricultural product processing includes a screening box 1, two doors 2, two screening frames 12, and a controller 20. Multiple mounting blocks 3 are fixedly connected to both inner walls of the screening box 1. Two connecting blocks 14 are fixedly connected to both side walls of the screening frames 12. The mounting blocks 3 are connected to the lower ends of adjacent connecting blocks 14 via shock absorbers 4. A maintenance plate (not shown in the figure) is provided on the left side of the screening box 1. The maintenance plate is connected to the screening box 1 by screws. A maintenance opening is provided on the left side wall of the screening box 1 for removing the first screen plate 10 and the second screen plate 15. Notably, the mounting blocks 3 have an L-shaped cross-section. The distance between two mounting blocks 3 at the same height and in the front-to-back direction is greater than the front-to-back width of the first screen plate 10 and the second screen plate 15. Therefore, the first screen plate 10 and the second screen plate 15 can be removed from the two mounting blocks 3 in the front direction. Additionally, a discharge port is provided at the back of the screening box 1, which is not shown in the figure.

[0025] The screening box 1 is equipped with a material guiding mechanism for introducing agricultural products. The material guiding mechanism includes a rotating cylinder 7 fixedly connected to the screening box 1. A feeding hopper 6 is connected to the rotating cylinder 7. A drive motor 8 is fixedly connected to the upper end of the rotating cylinder 7. A rotating disk 5 is fixedly connected to the output shaft of the drive motor 8. Multiple material dropping holes 9 are opened at the upper end of the rotating disk 5. A material guiding port is opened at the lower end of the rotating cylinder 7. Vibration motors 11 are provided on both sides of the screening frame 12. A first screen plate 10 is provided in one of the screening frames 12. Two receiving frames 13 are fixedly connected to the side wall of the screening box 1. An opening is opened at the upper end of the receiving frame 13 in the figure.

[0026] Another screening frame 12 is equipped with a filtering mechanism for filtering agricultural products. The filtering mechanism includes a second screen plate 15 set in the screening frame 12. The receiving frame 13 is equipped with a guide pipe 16 that communicates with its interior, which can centrally discharge the material in the receiving frame 13.

[0027] In this utility model, two fixing blocks 18 are fixedly connected to both inner walls of the screening frame 12. Multiple bolts 17 are provided at the lower end of the first screen plate 10, so that the first screen plate 10 and the second screen plate 15 can be disassembled. This makes it convenient for the equipment to add the second screen plate 15 when needed and remove it when not needed. For example, the dry peanut screening can separate peanuts with shells from peanut kernels that have been shelled.

[0028] In this invention, the two fixing blocks 18 have triangular cross sections, which can more quickly concentrate the agricultural products in the first screen plate 10 and the second screen plate 15 towards the center and speed up their discharge. The bottom of the screening box 1 is provided with an inclined surface to facilitate the discharge of agricultural products.

[0029] In this utility model, the feed hopper 6 is provided with a sealing cover to prevent dust from entering. The sealing cover can be threaded to the feed hopper 6. Multiple discharge holes 9 are set at equal intervals. The upper and lower side walls of the rotating disk 5 are slidably connected to the inside of the central rotating cylinder 7.

[0030] In this utility model, the side wall of the box door 2 is provided with a maintenance door 19, and the side wall of the maintenance door 19 is provided with multiple screws, so that maintenance of some components can be performed without disassembling the entire box door 2.

[0031] When in use, remove the sealing cover on the feed hopper 6, and feed the primary agricultural products into the feed hopper 6. The agricultural products enter the discharge hole 9 of the rotating disc 5. Start the drive motor 8, and the drive motor 8 drives the rotating disc 5 to rotate at a uniform speed. The agricultural products in the feed hopper 6 fall into the discharge hole 9 of the rotating disc 5. Since the discharge holes 9 are evenly distributed and the rotation speed of the rotating disc 5 can be controlled at 5-10 revolutions per minute, the agricultural products pass through the guide port at the lower end of the central rotating cylinder 7 at even intervals and fall into the screening frame 12 in the screening box 1 in batches, avoiding the problem of concentrated accumulation in the traditional tilting method.

[0032] Agricultural products fall onto the first screen plate 10. The screening frame 12 with the first screen plate 10 generates high-frequency vibration through the vibration motor 11. Larger impurities such as stones and straw are intercepted, while agricultural products that meet the particle size requirements pass through the screen holes and fall into the lower screening frame 12. The screening frame 12 with the second screen plate 15 performs secondary screening of the material, further separating agricultural products of different specifications such as whole particles and broken particles. During the vibration, the triangular fixing block 18 guides the material to concentrate in the middle of the screen plate. Combined with the inclined bottom of the screening box 1, it ensures that the material passes through the screen evenly and avoids retention.

[0033] After screening, the agricultural products fall into the receiving frames 13 on both sides and are collected in a concentrated manner through the guide pipe 16. Impurities are discharged from the discharge port at the rear end of the screening box 1. The controller 20 can link the frequency of the vibration motor 11 and the rotation speed of the rotating disk 5 to adapt to the screening needs of different agricultural products such as peanuts and corn.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
