Description

Technical Field

[0001] This invention relates to the field of sieving granular crops, specifically to a two-stage vibrating sieving device for various types of granular crops. Background Technology

[0002] In modern agricultural production, the screening and grading of granular crops is crucial. To improve production efficiency and ensure the quality of the final product, vibrating screens have become key equipment, primarily serving functions such as crop transportation and vibrating screening. However, current granular crop screening devices are only designed for single crops, requiring manual screen replacement to screen multiple types of granular crops. This results in complex production lines, low screening efficiency, and high maintenance costs. Therefore, a device capable of screening multiple types of granular crops separately is needed.

[0003] To address the above problems, this invention provides a two-stage vibrating sieving device for various types of granular crops. It includes a crop transfer module, a primary sieving module, a secondary sieving module, and a housing. The housing adopts an integral structure, with the crop transfer module connected to it to allow movement of the granular crops. The sieving module features a rotatable screen whose aperture size can be adjusted to accommodate crops of different particle sizes. Two different vibration modes are used to vibrate the screen to achieve the sieving effect. Finally, the sieving granular crops accumulate on the lower surface of the housing, and can be removed through pre-drilled slots on the lower surface. The coordinated operation of these modules gives this invention the advantages of replacing some manual labor, enabling sieving of various types of granular crops, high efficiency, and low cost, thus solving the problems of limited granular crop sieving, low efficiency, and high cost. Summary of the Invention

[0004] The purpose of this invention is to provide a method that can replace some manual labor, perform secondary screening of various types of granular crops, and is highly efficient and low-cost.

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

[0006] A two-stage vibrating sieving device for various types of granular crops includes a crop transfer module (1), a primary sieving module (2), a secondary sieving module (3), and a housing (4). The crop transfer module (1) is fixed to the lower inner surface of the housing (4) by bolts, thus fixing the entire device. The primary sieving module (2) is embedded and fixed to the outer surface of the crop transfer module (1) for preliminary sieving of crops with larger particle sizes. The secondary sieving module (3) is fixed to the lower inner surface of the housing (4) by a shaft support, thus achieving secondary sieving of the crops.

[0007] Furthermore, as a preferred embodiment, the crop transfer module (1) includes a particle inflow guide funnel (1-1), a primary particle sliding guide rail (1-2), a secondary particle sliding guide rail (1-3), and a large particle collection trough (1-4). The particle inflow guide funnel (1-1) is embedded and fixed in a groove reserved on the upper surface of the primary screen, while the primary particle sliding guide rail (1-2) is connected to the lower surface of the primary screen by screws. The secondary particle sliding guide rail (1-3) is fixed by steel columns connected to both sides of the box (4), and the large particle collection trough (1-4) is fixed to the lower inner surface of the box (4) by bolts. Crops can be classified and summarized according to particle size through a series of sliding transfer devices to achieve the sieving function.

[0008] Furthermore, as a preferred embodiment, the primary screening module (2) includes a primary vibration table (2-1), a primary vibration support plate (2-2), a primary screen (2-3), a vibration transmission spring (2-4), a spring support plate (2-5), an eccentric rocker arm (2-6), and a kinetic energy storage spring (2-7). The primary vibration table (2-1) and the primary vibration support plate (2-2) are embedded and fixed to the outer surface of the guide funnel (1-1), while the primary screen (2-3) is embedded in the pre-reserved holes inside the primary vibration table (2-1) to form a fixed structure. The lower end of the vibration transmission spring (2-4) is connected to the spring support plate (2-5), and the upper end is connected to the lower surface of the primary vibration table (2-1) through a connecting plate. The eccentric rocker arm (2-6) is also included. The crank handle (2-6) is connected to both sides of the spring support plate (2-5) via a shaft. The upper end of the kinetic energy storage spring (2-7) is connected to the spring support plate (2-5), and the lower end is fixed. When the eccentric crank handle (2-6) rotates downward, it compresses the kinetic energy storage spring (2-7) to accumulate elastic potential energy. When the eccentric crank handle (2-6) rotates upward, it converts the elastic potential energy stored in the kinetic energy storage spring (2-7) into kinetic energy and transmits it to the vibration transmission spring (2-4) to generate elastic potential energy. Finally, the vibration transmission spring (2-4) drives the first-stage vibration table (2-1) to move up and down. When the three sets of vibration transmission springs (2-4) work at different frequencies, the first-stage vibration table (2-1) vibrates to achieve the effect of sieving crop particles by vibration.

[0009] Furthermore, as a preferred embodiment, the secondary screening module (3) includes a multi-diameter rotating screen (3-1), a screen rotation drive gear (3-2), a secondary vibration support plate (3-3), a retractable rotating stepped shaft (3-4), a spring fixing seat (3-5), a kinetic spring tension rod (3-6), a spring upper support seat (3-7), a rotating shaft (3-8), and an eccentric wheel (3-9). The multi-diameter rotating screen (3-1) and the screen rotation drive gear (3-2) are connected by pins. The retractable rotating stepped shaft (3-4) is bolted to the lower inner surface of the housing (4) to achieve a fixed effect. When the retractable rotating stepped shaft (3-4) rotates, it drives the multi-diameter rotating screen (3-1) to rotate, so that the screen holes of different diameters are aligned with the primary particle sliding guide rail (1-2) to achieve screening of different particle diameters. The secondary vibration support plate (3-3) is fixed to the retractable rotating shaft through the shaft hole. The outer surface of the stepped shaft (3-4); the spring fixing seat (3-5) is fixed to the upper surface of the secondary vibration support plate (3-3) by screws to achieve the supporting effect, and is used to support the entire vibration device; the upper spring support seat (3-7) is connected to the lower surface of the multi-diameter rotating screen (3-1) by screws; the bottom end of the kinetic energy spring tension rod (3-6) is connected to the top end of the eccentric wheel (3-9) by screws; the rotating shaft (3-8) is connected to the center of the eccentric wheel (3-9) by an embedded manner, when When the kinetic spring tension rod (3-6) moves downward, it drives the eccentric wheel (3-9) to rotate, which in turn drives the rotating shaft (3-8) to rotate. At the same time, the central spring is stretched and accumulates elastic potential energy. When the kinetic spring tension rod (3-6) moves upward, the eccentric wheel (3-9) returns sharply, converting the elastic potential energy of the spring into kinetic energy and generating vibration. When the three sets of kinetic spring tension rods (3-6) work at different frequencies, the multi-diameter rotating screen (3-1) vibrates to achieve the effect of sieving crop particles by vibration.

[0010] The beneficial effects of this invention are:

[0011] This invention provides a two-stage vibrating sieving device for various types of granular crops. It includes a crop transfer module, a primary sieving module, a secondary sieving module, and a housing. The housing adopts an integral structure, with one side removed for easier observation. Two different vibrating devices are installed in the two sieving modules to generate different vibrations for vibrating sieving. Furthermore, a retractable rotating stepped shaft is added to the secondary sieving module, which can drive a multi-diameter rotating screen to accommodate granular crops of different sizes. The crop transfer device is fixedly installed inside the housing, allowing granular crops to accurately enter the sieving modules via a slide rail, and then be collected after sieving. The cooperation of these modules enables this invention to replace some manual labor, sieving various types of granular crops by particle size, with high efficiency and low cost, solving the current problems of inefficiency and high cost associated with the inability to sieving multiple types of granular crops on a single machine.

The primary vibration table (2-1) and the primary vibration support plate (2-2) are embedded and fixed to the outer surface of the guide funnel (1-1) to provide stable support for vibration. The primary screen (2-3) is embedded in the pre-reserved holes inside the primary vibration table (2-1) to achieve sieving operation. The vibration transmission spring (2-4)... The lower end is connected to the spring support plate (2-5), and the upper end is connected to the lower surface of the first-stage vibration table (2-1) through a connecting plate. Vibration is generated when the spring deforms. The eccentric rocker (2-6) is connected to both sides of the spring support plate (2-5) through a shaft.

The top end of the kinetic energy spring tension rod (3-6) is connected to the upper support seat (3-7) of the spring, and the bottom end is connected to the top end of the eccentric wheel (3-9) by screws. The rotating shaft (3-8) and the center of the eccentric wheel (3-9) are connected by an embedded method. The above three parts cooperate with each other. When the kinetic energy spring tension rod (3-6) moves downward, it will drive the eccentric wheel (3-9) to rotate, which in turn drives the rotating shaft (3-8) to rotate. At the same time, the central spring is stretched and accumulates elastic potential energy. When the kinetic energy spring tension rod (3-6) moves upward, the eccentric wheel (3-9) returns sharply, converting the elastic potential energy of the spring into kinetic energy and generating vibration. The four sets of vibration devices cooperate with each other to make the screen move in a specific way to achieve the effect of sieving.
