[0005] To address the shortcomings of existing technologies, this invention provides a seed particle grading and screening structure with advantages such as grading and swing screening. It solves the problem that existing screening structures lack grading and screening functions, cannot screen seeds into different particle size categories, and result in uneven seed particle size and poor screening effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A seed particle grading and screening structure includes a support frame, and a screening and shaking component for grading and swinging screening is provided on the inner side of the support frame.

[0008] The screening and shaking assembly includes a first drive disk and a second drive disk rotatably connected to the inner side of the support frame. A shaking barrel is fixedly installed between the first drive disk and the second drive disk. A screening cylinder is snapped into the inner side of the shaking barrel. Three screening plates are fixedly installed inside the screening cylinder. A screen is fixedly connected to the inner side of the screening plate. A drive motor is fixedly connected to the right side of the support frame. A sector gear is installed on the output shaft of the drive motor. A driven gear is installed on the outside of the first drive disk.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 3 This embodiment of a seed particle grading and screening structure includes a support frame 1, with a screening and shaking assembly for grading and shaking screening disposed on the inner side of the support frame 1. The screening and shaking assembly includes a first drive disk 2 and a second drive disk 3 rotatably connected to the inner side of the support frame 1. A shaking barrel 4 is fixedly installed between the first drive disk 2 and the second drive disk 3. A screening cylinder 5 is snapped into the inner side of the shaking barrel 4. Three screening plates 6 are fixedly installed inside the screening cylinder 5. Screens 7 are fixedly connected to the inner side of the screening plates 6. A drive motor 8 is fixedly connected to the right side of the support frame 1. A sector gear 9 is installed on the output shaft of the drive motor 8. A driven gear 10 is installed on the outside of the first drive disk 2. The three screening plates 6 inside the screening cylinder 5 can use the screens 7 with different aperture sizes to grade and screen the seed particles. Seed particles of different sizes will remain on the top of their respective screening plates 6, while dust and slag will fall to the bottom wall of the screening cylinder 5.

[0025] During this period, the drive motor 8 can drive the sector gear 9 to rotate clockwise or counterclockwise. Under the meshing transmission between the sector gear 9 and the driven gear 10, the toothed part will rotate, while the driven gear 10 is in a stopped state during the contact time of the toothless part, thus realizing intermittent motion transmission. This causes the shaking barrel 4 to swing back and forth inside the support frame 1, so as to evenly shake the screening cylinder 5 and make the seed particles roll back and forth on the outer surface of the screen 7, thereby improving the screening effect.

[0026] In this embodiment, a slide rail 11 is fixedly connected to the inner bottom wall of the support frame 1, and a tray 12 for collecting fallen seed particles is slidably connected to the inner side of the slide rail 11. The slide rail 11 and the tray 12 can collect seed particles that are accidentally dropped by the staff during loading, thereby collecting them and preventing spillage.

[0027] It should be noted that the screening cylinder 5 has a material inlet 13 on both the front and back, and a magnetic baffle 14 on both the front and back. The material inlet 13 and the magnetic baffle 14 can facilitate the removal of seed particles of different sizes and clean up dust and slag.

[0028] Specifically, the three screening plates 6 have different aperture sizes for their respective screens 7, and the screens 7 are made of plastic.

[0029] It should be noted that the sector gear 9 meshes with the driven gear 10 for transmission, and handles are fixedly connected to both the left and right sides of the top of the screening cylinder 5. The handles make it easy for the staff to lift the screening cylinder 5 out of the shaking barrel 4 for material discharge.

[0030] Specifically, the support frame 1 is made of stainless steel, and the first drive disk 2 and the second drive disk 3 are the same size.

[0031] It should be noted that a base 15 is provided at the bottom of the support frame 1, and steps 16 are fixedly connected to the front and back of the base 15. The base 15 and the steps 16 serve to elevate the frame, making it easier for workers to load materials.

[0032] Specifically, pin sleeves 17 are fixedly connected to both the left and right sides of the base 15 and the support frame 1. Pins 18 are inserted into the inner side of the pin sleeves 17. The pin sleeves 17 and pins 18 can limit the base 15 to the bottom of the support frame 1, thereby enhancing the stability of the support frame 1. At the same time, it is also convenient for workers to disassemble and assemble.

[0033] The working principle of the above embodiments is as follows:

[0034] In use, the operator first pours the seed particles into the screening cylinder 5 from the top. Inside the screening cylinder 5, three screening plates 6 with different aperture sizes 7 categorize the seed particles into different size classes. During screening, the drive motor 8 is activated, causing the sector gear 9 to rotate clockwise or counterclockwise. The meshing transmission between the sector gear 9 and the driven gear 10 causes rotation in the toothed portion, while the toothed portion rotates during the contact period. When the device is in a stopped state, intermittent motion transmission is achieved, causing the shaking drum 4 to swing back and forth inside the support frame 1. This evenly shakes the screening drum 5, causing the seed particles to roll back and forth on the outer surface of the screen 7. Subsequently, seed particles of different sizes will stop on the top of their respective screening plates 6, while dust and slag will fall to the bottom wall of the screening drum 5. After screening is completed, the drive motor 8 is stopped, and the operator lifts the screening drum 5 out of the shaking drum 4 using the handle and removes the magnetic baffle 14. Seed particles of different sizes can then be taken out from the feeding port 13, and the dust and slag can be cleaned.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
