[0016] The present invention will be further described below with reference to the accompanying drawings.
[0017] like Figure 1 A vegetable seed air-screening device is shown, comprising a housing 1, a feed hopper 2 fixedly connected to the upper end of the housing 1, and a partition 5 fixedly connected to the top of the bottom plate of the housing 1. To facilitate seed screening based on volume, a coarse sieve plate 8 and a fine sieve plate 9 are sequentially connected at an incline from top to bottom on the left side of the partition 5, and a drain basket 22 is detachably connected to the right side. For easy collection of screened seeds, the lower ends of the coarse sieve plate 8 and the fine sieve plate 9 extend through the side wall of the housing 1 to the outside of the housing 1, while the higher ends are hinged to the partition 5. A first eccentric roller 10 is provided below the coarse sieve plate 8, and a second eccentric roller 30 is provided below the fine sieve plate 9. To ensure that heavy impurities are introduced into the drain basket 22, a guide stone plate 7 is inclinedly provided above the coarse sieve plate 8, and the guide stone plate 7 is fixedly connected to the housing 1. The lower end of the guide stone plate 7 extends above the drain basket 22. An L-shaped plate 6 is fixedly connected to the upper left side of the housing 1. To facilitate the collection of light impurities, a settling device is connected to the right end of the L-shaped plate 6. The other end of the settling chamber 18 is fixedly connected to the inner wall of the shell 1 via a connecting plate 15. A fan baffle 16 is fixedly connected to the top plate of the shell 1. The lower end of the fan baffle 16 is fixedly connected to the connecting plate 15. In order to facilitate the separation of seeds and impurities, a light impurity fan 11 and a heavy impurity fan 17 are fixedly connected to the upper inner wall of the shell 1. The output end of the light impurity fan 11 faces the upper part of the L-shaped plate 6. A fixed plate 19 is set above the drain basket 22. The output end of the heavy impurity fan 17 faces the upper part of the guide stone plate 7. In order to facilitate the cleaning of the soil that carries the seeds, a spray pipe 20 is fixedly connected to the lower part of the fixed plate 19. One end of the spray pipe 20 passes through the shell 1 and is connected to the water tank. Several nozzles 21 facing the drain basket 22 are fixedly connected to the lower end of the spray pipe 20. In order to drain the mud and water in time, the bottom right side of the shell 1 is connected to the mud and water tank 27 via a mud and water pipe 25. A water pump 26 is connected to the mud and water pipe 25. A seed-separating pool 3 is set outside the shell 1.
[0018] It should be noted that both the light-duty fan 11 and the heavy-duty fan 17 in this utility model are variable frequency fans. During operation, the wind force of the heavy-duty fan 17 is greater than that of the light-duty fan 11.
[0019] In order to control the speed at which seeds enter the shell 1 and improve the stability of the feed hopper 2, a star-shaped discharge valve is connected to the bottom of the feed hopper 2, and reinforcing ribs 12 are fixedly connected to both sides of the feed hopper 2. The other end of the reinforcing ribs 12 is fixedly connected to the upper end of the shell 1.
[0020] In order to control the rotation of the first eccentric roller 10 and better distinguish seeds according to volume, the first eccentric roller 10 is rotatably connected to the inner wall of the housing 1, one end of the first eccentric roller 10 is connected to the output end of the first eccentric roller motor, and the second eccentric roller 30 is rotatably connected to the inner wall of the housing 1, one end of the second eccentric roller 30 is connected to the output end of the second eccentric roller motor.
[0021] To prevent seeds from entering the settling chamber 18 due to collision with the L-shaped plate 6 during the process of entering the shell 1, a baffle plate 13 is fixedly connected to the top plate inside the shell 1, and the baffle plate 13 is set above the L-shaped plate 6.
[0022] To facilitate the removal or placement of the drain basket 22 and to prevent any undrained mud and water from overflowing when the cleaning door is opened, a wing plate 23 is fixedly connected to the upper end of the drain basket 22. One side of the wing plate 23 is slidably connected to the inner wall of the housing 1, and the other side is connected to the upper end of the partition plate 5. A mud and water trough 24 is provided below the drain basket 22, and the mud and water trough 24 is connected to the mud and water pipe 25.
[0023] To facilitate cleaning the internal structure of the housing 1 and removing the drain basket 22, a cleaning door is hinged to the housing 1.
[0024] To facilitate the collection of dust from light impurities, a dust collection bag 29 is provided at the upper end of the housing 1. The dust collection bag 29 is connected to the housing 1 through a dust collection pipe 28. The other end of the dust collection pipe 28 passes through the housing 1 and is located on the right side of the baffle plate 13. A dust extraction fan 14 is fixedly connected to the dust collection pipe 28, and the output end of the dust extraction fan 14 is connected to the dust collection bag 29.
[0025] To improve the stability of the dust collection bag 29, an anti-tipping frame 4 is fixedly connected to the upper end of the housing 1, and the dust collection bag 29 is placed inside the anti-tipping frame 4.
[0026] The working process of this embodiment is as follows:
[0027] When seeds need to be air-screened, they are first poured into the feed hopper 2, and the seed feeding speed is controlled by the star-shaped discharge valve. At this time, the light impurity fan 11 is turned on, acting on the seeds that have just entered the shell 1, so that the light impurities are separated from the seeds. The light impurities enter the settling chamber 18 along the right side of the L-shaped plate 6. The dust in the light impurities is introduced into the dust collection pipe 28 by the dust induction fan 14, and then flows into the dust collection bag 29. The seeds fall along the left side of the L-shaped plate. Under the action of the heavy impurity fan 17, the seeds are separated from the heavy impurities. The heavy impurities fall into the drain basket 22 along the guide plate 7, and the seeds continue to fall to the top of the coarse screen plate 8. By controlling the first eccentric roller motor to rotate the first eccentric roller 10 and the second eccentric roller motor to rotate the second eccentric roller 30, the coarse screen plate 8 and the fine screen plate 9 vibrate. During the vibration, small seeds and fallen fine impurities are separated. The coarse sieve plate 8's holes fall above the fine sieve plate 9, and the fine impurities fall through the holes of the fine sieve plate 9 onto the bottom plate of the shell 1. The screened seeds, under the influence of vibration and gravity, leave the shell 1 along the inclined direction of the coarse sieve plate 8 and the fine sieve plate 9. When the heavy impurities fall into the drain basket 22 along the guide stone plate 7, clean water is introduced from the water tank into the spray pipe 20, and then sprayed onto the heavy impurities through the nozzle 21 to wash away the soil and fall to the bottom of the shell 1. The muddy water is introduced into the muddy water pipe 25 by the water pump 26, and then flows into the muddy water tank 27. After the air screening is completed, the hinged cleaning door of the shell 1 is opened to clean the light impurities accumulated under the fine sieve plate 9 at the bottom of the shell 1 and the light impurities in the settling chamber. Then the drain basket 22 is taken out and placed into the seed separation pool 3. The specific gravity liquid in the seed separation pool 3 separates the seeds and stones, and the seeds are collected.
