Description

Technical Field

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

[0002] Agricultural products are goods produced in agriculture. To facilitate the sale of agricultural products according to their quality and grade, they need to be screened after harvesting using screening equipment. Screening is a crucial step in both production and sales. Traditional agricultural product screening equipment mostly uses screening discs with different aperture sizes inside the screening device. As agricultural products pass through the screening discs of different aperture sizes, they are screened and graded. This requires preparing multiple screening discs of different aperture sizes, which increases costs. Furthermore, the screening discs need to be frequently changed for agricultural products of different sizes, increasing the labor intensity of workers and making the equipment inconvenient to use.

[0003] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0004] To solve the problems mentioned in the background art, the present invention is achieved through the following technical solution: a screening device for agricultural product processing, including a base, a support leg installed on the base, and a screening structure installed on the support leg;

[0005] The screening structure consists of two screening components and multiple first electric push rods, with the multiple first electric push rods disposed between the two screening components, and the two screening components being arranged vertically and vertically in correspondence.

[0006] Each of the sieving components includes a spiral frame, and multiple rotating rods are inserted at equal intervals on the inner wall of the spiral frame. Each rotating rod is fixedly inserted with a sieve rod at the inside of the spiral frame. The cross-sectional shape of the sieve rod is an elliptical structure.

[0007] Each of the multiple rotating rods has a gear fixedly mounted on one end, and a drive assembly is connected to the gear.

[0008] Preferably, the drive assembly includes a guide groove, which is formed on the outer wall of the U-shaped frame. A guide strip is movably inserted into the guide groove, and a rack is installed on the guide strip. The rack meshes with a gear, and a second electric push rod is installed between the guide strip and the U-shaped frame.

[0009] Preferably, a collection box is provided on the upper wall of the base.

[0010] Preferably, a control panel is installed on one of the two sieving assemblies.

[0011] Preferably, both the guide groove and the guide strip have a T-shaped cross-sectional shape.

[0012] Preferably, a connecting frame is installed between the telescopic end of the second electric push rod and the rack, and a stabilizing frame is installed between the fixed end of the second electric push rod and the U-shaped frame.

[0013] Beneficial effects

[0014] This utility model provides a screening device for agricultural product processing, which has the following advantages compared with the prior art: By driving the component to work, multiple gears meshing with it rotate, and multiple rotating rods rotate, driving the screen rods to rotate. Since the cross-sectional shape of the screen rods is elliptical, the minimum distance between two adjacent screen rods can be adjusted as the screen rods rotate. Agricultural products fall from the minimum distance between two adjacent screen rods and are screened. The operation is simple and convenient, improving the efficiency of the equipment. In the upper and lower filter components, the minimum distance between two adjacent screen rods can be different, realizing multi-stage filtration. When one of the two screening components fails, that is, when the minimum distance between two adjacent screen rods cannot be adjusted, the filter component without failure can still screen different sizes by adjusting the minimum distance between two adjacent screen rods, without stopping the machine for maintenance, ensuring the continuity of screening work.

[0019] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example: Those skilled in the art shall connect all electrical components and their compatible power supplies in this case with wires, and select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence shall refer to the working principle described below, in which the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0021] Please see Figure 1-3 To address the problems of traditional agricultural product screening equipment, which mostly uses screening discs with different aperture sizes to screen and grade agricultural products, requiring multiple screening discs of different aperture sizes, increasing costs, and necessitating frequent replacement of screening discs for different sized agricultural products, thus increasing the labor intensity of workers and causing inconvenience, this technical solution is designed. The detailed technical solution is as follows:

[0022] A screening device for agricultural product processing includes a base 1, a support leg 2 mounted on the base 1, and a screening structure mounted on the support leg 2.

[0023] Specifically, the screening structure consists of two screening components and multiple first electric push rods 3, with the multiple first electric push rods 3 positioned between the two screening components, and the two screening components being positioned vertically and vertically respectively.

[0024] It should be noted that the two screening components can perform screening work simultaneously or independently. The distance between the two screening components can be adjusted by extending and retracting the first electric push rod 3. When it is necessary to clean the screening components, the distance between the two screening components is increased by extending the first electric push rod 3, which makes it easier to clean the screening component located below.

[0025] Specifically, each screening component includes a spiral frame 4, with multiple rotating rods 5 inserted at equal intervals on the inner wall of the spiral frame 4. Each rotating rod 5 has a screen rod 6 fixedly inserted inside the spiral frame 4, and the screen rod 6 has an elliptical cross-sectional shape. A gear 7 is fixedly fitted at one end of each of the multiple rotating rods 5, and a drive component is connected to the gear 7.

[0026] It should be noted that by driving the component, multiple gears 7 meshing with it rotate, causing multiple rotating rods 5 to rotate, which in turn drives the sieve rods 6 to rotate. Since the cross-sectional shape of the sieve rods 6 is elliptical, the minimum distance between two adjacent sieve rods 6 can be adjusted as the sieve rods 6 rotate. Agricultural products fall from the minimum distance between two adjacent sieve rods 6 and are screened. The operation is simple and convenient, improving the efficiency of the equipment. In the upper and lower filter components, the minimum distance between two adjacent sieve rods 6 can be different, realizing multi-stage filtration. When one of the two sieve components fails, that is, when the minimum distance between two adjacent sieve rods 6 cannot be adjusted, the filter component without failure can still screen different sizes by adjusting the minimum distance between two adjacent sieve rods 6, without stopping the machine for maintenance, ensuring the continuity of the screening operation.

[0027] Specifically, the drive assembly includes a guide groove 8, which is opened on the outer wall of the loop frame 4. A guide bar 9 is movably inserted into the guide groove 8. A rack 10 is installed on the guide bar 9. The rack 10 meshes with the gear 7. A second electric push rod 11 is installed between the guide bar 9 and the loop frame 4.

[0028] It should be noted that by extending and retracting the second electric push rod 11, the guide bar 9 moves in the guide groove 8, and the rack 10 moves back and forth, driving the gear 7 to rotate.

[0029] As a preferred and further option, a collection box 12 is provided on the upper wall of the base 1 for collecting agricultural products filtered by the screening components below. One end of each of the two screening components can be used to receive agricultural products. Since this is not the content to be protected by this technical solution, it will not be described in detail here.

[0030] As a preferred and further option, one of the two screening components is equipped with a control panel 13. The control panel 13 has a built-in microcontroller that can be programmed with software. By writing a control program, the device can be controlled. Since this is existing technology, it will not be described in detail here.

[0031] Preferably, both the guide groove 8 and the guide bar 9 have a T-shaped cross-section to prevent the guide bar 9 from detaching from the guide groove 8.

[0032] As a preferred and further option, a connecting frame 14 is installed between the telescopic end of the second electric push rod 11 and the rack 10, and a stabilizing frame 15 is installed between the fixed end of the second electric push rod 11 and the U-shaped frame 4 for mounting the second electric push rod 11.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
