Description

Technical Field

[0001] This utility model belongs to the field of seed planting technology, and in particular relates to a green manure seed planting screening device. Background Technology

[0002] Different varieties are suitable for different regions and planting purposes. They are used as base fertilizer for early rice when intercropped in late rice fields. Common green manure crops also include vetch and alfalfa. According to plant classification, they can be divided into legume green manure and non-legume green manure. Varieties that are tolerant of waterlogging and drought, have well-developed root systems, are resistant to diseases and pests, have suitable growth periods, and have high fresh grass yields should be selected.

[0003] In the production of green manure crops, seeds need to be screened before planting. Unscreened green manure seeds generally contain impurities. Moreover, the screening process requires continuous feeding of the screening device's inlet. When using a screw conveyor, unstable shaking may occur. Therefore, we need to design a green manure seed planting and screening device with a screw feeding structure to avoid the equipment running idle due to intermittent manual feeding, thus achieving continuous screening operations. A stable feeding speed can ensure that the green manure seeds are evenly distributed in the screening device, reducing local accumulation or feeding gaps caused by uneven feeding, ensuring the consistency of green manure seed screening standards. In addition, the green manure seed feeder is relatively stable and does not shake during feeding. Utility Model Content

[0004] The purpose of this invention is to provide a green manure seed planting and screening device, which has a stable feeding speed that allows the green manure seeds to be evenly distributed in the screening device, reducing local accumulation or feeding gaps caused by uneven feeding of green manure seeds, ensuring the consistency of green manure seed screening standards, and the green manure seed feeder has the advantage of being relatively stable and not shaking during feeding, so as to solve the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A green manure seed planting screening device includes a screening machine frame, a multi-layer screening sieve installed in the inner cavity of the screening machine frame, a screening discharge port connected to the front side of each multi-layer screening sieve, a screening feed port fixedly connected to the rear side of the top of the screening machine frame, the screening feed port being located at the top of the multi-layer screening sieve, a push frame provided on the rear side of the screening machine frame, a vibration motor installed on the rear side of the top right side of the screening machine frame, a spiral blade installed on the top of the push frame, the output shaft of the vibration motor being fixedly connected to the spiral blade, two symmetrical threaded rods provided at the bottom of the spiral blade, and a hexagonal plate fixedly connected to the bottom of each of the two threaded rods.

[0006] Preferably, the front side of the bottom of the spiral blade is fixedly connected to a discharge port, which is located at the top of the screening inlet.

[0007] Preferably, the top of the rear side of the spiral blade is fixedly connected to a feed inlet.

[0008] Preferably, a fixing ring is fixedly connected to the top of the left side of the push frame, and the inner cavity of the fixing ring is tightly fitted with the spiral blade.

[0009] Preferably, a lower base plate is fixedly connected to the top of the push frame, and the lower base plate is slidably connected to two threaded rods.

[0010] Preferably, both threaded rods are threaded with fastening caps, and the four corners of the bottom of the push frame are equipped with mounting wheels.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model uses a vibrating motor, spiral blades and feed inlet in combination to feed the inner cavity of the screening inlet through the discharge port, which in turn allows the multi-layer screening screen to screen and process the green manure seeds. Finally, after the multi-layer screening screen is completed, the green manure seeds flow out through the screening discharge port. This achieves a stable feeding speed, which allows the green manure seeds to be evenly distributed in the screening device, reducing local accumulation or feeding gaps caused by uneven feeding of green manure seeds, ensuring the consistency of green manure seed screening standards, and making the green manure seed feeder more stable and less shaky during feeding.

[0013] 2. By setting a fixing ring, this utility model keeps the spiral blades in a fixed position and angle, so that the seed material is accurately delivered to the inner cavity of the screening inlet, ensuring precise connection of subsequent processes, improving the accuracy and consistency of the entire production process, avoiding additional wear and vibration caused by the shaking of the spiral blades, and reducing the stress on the components.

[0014] 3. By setting a fastening cap, this utility model can effectively limit the sliding or displacement of the hexagonal plate on the ground by fixing the threaded rod with the fastening cap, ensuring that the spiral blade remains in a stable position during operation, avoiding changes in the position of the spiral blade due to external forces, making the contact state between the hexagonal plate and the ground more stable, and enhancing the stable support for the push frame.

[0023] In the following description, embodiments of the green manure seed planting and screening device of this invention will be described with reference to the accompanying drawings.

[0024] Figure 1-5This invention illustrates a green manure seed planting screening device according to an embodiment of the present invention. It includes a screening frame 1, with a multi-layer screening sieve 2 installed in the inner cavity of the frame 1. Each multi-layer screening sieve 2 has a screening outlet 3 connected to its front side. A screening inlet 4 is fixedly connected to the rear side of the top of the screening frame 1, located at the top of the multi-layer screening sieve 2. A pusher frame 5 is provided on the rear side of the screening frame 1. A vibration motor 6 is installed on the rear side of the top right side of the screening frame 1. A spiral blade 7 is installed on the top of the pusher frame 5. The output shaft of the vibration motor 6 is fixedly connected to the spiral blade 7. An outlet 8 is fixedly connected to the front side of the bottom of the spiral blade 7, located at the top of the screening inlet 4. An inlet 9 is fixedly connected to the top of the rear side of the spiral blade 7. A fixing ring 10 is fixedly connected to the top of the left side of the pusher frame 5. The inner cavity of the fixing ring 10 is tightly fitted with the spiral blade 7. The fixing ring 10 ensures that the spiral blade 7 maintains a fixed position and angle, allowing for [further processing / control]. The seed material is accurately conveyed to the inner cavity of the screening inlet 4, ensuring precise connection of subsequent processes, improving the accuracy and consistency of the entire production process, avoiding additional wear and vibration caused by the shaking of the spiral blade 7, and reducing the stress on the components. The bottom of the spiral blade 7 is provided with two symmetrical threaded rods 12, and the bottom of each threaded rod 12 is fixedly connected to a hexagonal plate 13. The top of the push frame 5 is fixedly connected to a lower base plate 11, which is slidably connected to the two threaded rods 12. The surfaces of the two threaded rods 12 are threadedly connected with fastening caps 14. The four corners of the bottom of the push frame 5 are equipped with mounting wheels 15. By setting the fastening caps 14 and fixing the threaded rods 12, the sliding or displacement of the hexagonal plate 13 on the ground can be effectively restricted, ensuring that the spiral blade 7 remains stable during operation and preventing the spiral blade 7 from changing position due to external forces. This makes the contact state between the hexagonal plate 13 and the ground more stable and enhances the stable support for the push frame 5.

[0025] Working principle: When using this utility model, the user pushes the pusher frame 5 to the rear of the screening machine frame 1. The pusher frame 5 drives the mounting wheel 15 to roll, thus completing the movement of the pusher frame 5. Then, the user rotates the fastening cap 14 on the surface of the threaded rod 12, causing the threaded rod 12 to loosen from the lower base plate 11. The threaded rod 12 slides downward on the surface of the lower base plate 11, causing the hexagonal plate 13 to fit tightly against the ground. Then, the user rotates the fastening cap 14, which fixes the threaded rod 12, restricting the sliding or displacement of the hexagonal plate 13 on the ground. 3. With a more stable contact with the ground, the vibration motor 6 is then started. The output shaft of the vibration motor 6 drives the spiral blades 7 to rotate, thereby pouring the green manure seeds into the inner cavity of the feed inlet 9. The green manure seeds will move to the position of the discharge outlet 8 through the spiral blades 7, so that the green manure seeds are conveyed to the inner cavity of the screening feed inlet 4 through the discharge outlet 8. The green manure seeds will flow into the multi-layer screening screen 2, which will screen the green manure seeds layer by layer, so that green manure seeds of different qualities in each layer will flow out from the discharge outlet 3. Finally, the entire screening and processing process of green manure seeds is completed.

[0026] In summary, this green manure seed planting and screening device, through the coordinated use of the vibrating motor 6, the spiral blades 7, and the feed inlet 9, allows the discharge outlet 8 to feed the inner cavity of the screening feed inlet 4, which in turn causes the multi-layer screening sieve 2 to screen and process the green manure seeds. Finally, after the multi-layer screening sieve 2 completes the screening, the green manure seeds flow out through the screening discharge outlet 3. This achieves a stable feeding speed, ensuring that the green manure seeds are evenly distributed within the screening device, reducing local accumulation or feeding gaps caused by uneven feeding, ensuring consistent screening standards for green manure seeds, and making the green manure seed feeder relatively stable and undisturbed during feeding.
