Abstract
Description
Technical Field
[0001] This utility model relates to the field of seed screening technology, and more specifically, to a multifunctional seed screening device. Background Technology
[0002] A color sorter is a device that automatically separates discolored particles from granular materials based on differences in their optical properties using photoelectric detection technology. It is commonly used for seed screening, enabling non-destructive screening while being easy and efficient to operate, greatly improving the efficiency and quality of seed screening. It is a common type of screening equipment.
[0003] Based on the above, the inventors have found that existing screening equipment mainly performs color sorting, which has a relatively simple function. During the seed screening process, it is not easy to clean the impurities carried by the seeds and the dust and impurities stirred up by the rolling, resulting in a poor screening environment. Therefore, in view of this, the inventors have studied and improved the existing structure to provide a multifunctional seed screening device, in order to achieve a more practical purpose. Utility Model Content
[0004] 1. Technical problems to be solved
[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a multifunctional seed screening device. This solution is equipped with a dust cleaning component, which can centrally treat the dust and impurities stirred up during the seed rolling process, purify the screening environment, and is equipped with a baffle component, which can adjust the baffle of the falling seeds, improve the rolling impact force of the seeds, and make the impurities and dust on the seed surface fall off better.
[0006] 2. Technical Solution
[0007] To solve the above problems, the present invention adopts the following technical solution.
[0008] A multifunctional seed screening device includes a color sorting chamber, a conveying plate fixedly connected to the top of the color sorting chamber, an air pump and a fixed box fixedly connected to the top surface of the color sorting chamber, a suction pipe fixedly connected to one side of the fixed box, a baffle mechanism provided at the bottom of the conveying plate, a screening plate fixedly connected to the lower part of the interior of the color sorting chamber, and a first discharge port and a second discharge port opened at the bottom of the color sorting chamber. A material collection frame is slidably connected inside the fixed box.
[0009] The blocking mechanism includes a pair of rotating shafts, with a toothed column fixedly connected to the middle of the rotating shafts and a toothed disc fixedly connected to one end of the rotating shafts. A lifting plate is engaged with the side of the rotating shafts.
[0010] Furthermore, the input end of the air pump is fixedly connected to the fixed box, and a filter screen is fixedly connected to one side of the material collection frame.
[0011] Furthermore, a detector and a nozzle are fixedly connected to the upper part of the color sorting chamber, and the detector and the nozzle are arranged symmetrically.

[0014] Furthermore, the number of lifting plates is three, and the three lifting plates are staggered with the two rotating shafts, with the two gear plates meshing with each other.
[0015] Furthermore, a drive motor is provided on the outer side of one of the two toothed discs. The drive motor is fixedly connected to the conveyor plate, and the output end of the drive motor is fixedly connected to the corresponding toothed disc.
[0016] 3. Beneficial effects
[0017] Compared with existing technologies, the advantages of this utility model are:
[0018] (1) This solution places the seeds on a conveyor plate and rolls down along the conveyor plate. During the rolling process, the seeds collide with the conveyor plate, stirring up dust and impurities. During this process, the air pump is activated so that the suction pipe absorbs the splashed impurities and dust and sends them into the collection frame inside the fixed box. Compared with the existing technology, the dust cleaning component can be set up to centrally treat the dust and impurities stirred up during the rolling process and purify the screening environment.
[0019] (2) By setting up a baffle mechanism, two toothed discs are meshed together, so that the two rotating shafts move synchronously in opposite directions. The rotating shafts drive the toothed column to rotate, which in turn drives the lifting plate to move. The three lifting plates move up and down alternately, causing the surface of the conveying plate to be uneven, which increases the vibration force during the seed falling process. Compared with the existing technology, setting up a baffle assembly can adjust the falling seeds, increase the rolling impact force of the seeds, and make the impurities and dust on the seed surface fall off better.

Detailed Implementation
[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0026] Example:
[0027] Please see Figure 1-4 A multifunctional seed screening device includes a color sorting chamber 1, a conveying plate 2 fixedly connected to the top of the color sorting chamber 1, an air pump 3 and a fixed box 4 fixedly connected to the top surface of the color sorting chamber 1, a suction pipe 5 fixedly connected to one side of the fixed box 4, a baffle mechanism 6 provided at the bottom of the conveying plate 2, a screening plate 9 fixedly connected to the lower part of the interior of the color sorting chamber 1, and a first discharge port 10 and a second discharge port 11 opened at the bottom of the color sorting chamber 1. A material collection frame 12 is slidably connected inside the fixed box 4.
[0028] The blocking mechanism 6 includes a pair of rotating shafts 13. A toothed column 14 is fixedly connected to the middle of the rotating shaft 13, and a toothed disc 15 is fixedly connected to one end of the rotating shaft 13. A lifting plate 16 is meshed with the side of the rotating shaft 13. In order to improve the vibration force during the seed falling process and make the debris and dust on the seed surface fall off better, the blocking mechanism 6 is provided.
[0029] See Figure 3 The input end of the air pump 3 is fixedly connected to the fixed box 4. A filter screen is fixedly connected to one side of the collection frame 12. When the air pump 3 is started, the suction pipe 5 absorbs the splashed impurities and dust and sends them into the collection frame 12 inside the fixed box 4.
[0030] See Figure 2Inside the color sorting chamber 1, a detector 7 and a nozzle 8 are fixedly connected at the top. The detector 7 and the nozzle 8 are symmetrically arranged. When the seeds are placed on the conveyor plate 2, they roll down along the conveyor plate 2. When the seeds roll between the detector 7 and the nozzle 8, the detector 7 performs color sorting detection on the seeds. In conjunction with the nozzle 8, high-pressure air is sprayed onto the abnormal seeds, blowing them onto the screening plate 9. The normal seeds continue to fall along the bottom surface of the color sorting chamber 1.
[0031] See Figure 2 The first discharge port 10 is adapted to the lower part of the color sorting chamber 1, and the second discharge port 11 is adapted to the screening plate 9. Through the first discharge port 10 and the second discharge port 11, the seeds in different conditions after screening are discharged.
[0032] See Figure 4 The rotating shaft 13 and the lifting plate 16 are both located inside the conveying plate 2. The rotating shaft 13 is movably connected to the conveying plate 2, and the lifting plate 16 is slidably connected to the conveying plate 2. The rotating shaft 13 drives the toothed column 14 to rotate. Since the toothed column 14 is meshed with the lifting plate 16, it drives the lifting plate 16 to move.
[0033] See Figure 4 There are three lifting plates 16, and the three lifting plates 16 are staggered with the two rotating shafts 13. The two toothed discs 15 are meshed and connected, so that the three lifting plates 16 move up and down alternately, causing the surface of the conveyor plate 2 to be uneven, thereby increasing the vibration force during the seed falling process.
[0034] See Figure 4 A drive motor 17 is provided on the outer side of one of the two toothed discs 15. The drive motor 17 is fixedly connected to the conveyor plate 2, and the output end of the drive motor 17 is fixedly connected to the corresponding toothed disc 15. When the drive motor 17 is started, it drives the corresponding toothed disc 15 to rotate. Since the two toothed discs 15 are meshed, the two rotating shafts 13 move synchronously in opposite directions.
[0035] In use: Place the seeds on the conveyor plate 2, and the seeds roll down along the conveyor plate 2. During this process, start the air pump 3, so that the suction pipe 5 absorbs the splashed impurities and dust and sends them into the collection frame 12 inside the fixed box 4. At the same time, start the drive motor 17 to drive the corresponding toothed disc 15 to rotate. Since the two toothed discs 15 are meshed, the two rotating shafts 13 move synchronously in opposite directions. The rotating shafts 13 drive the toothed column 14 to rotate. Since the toothed column 14 is meshed with the lifting plate 16, it drives the lifting plate 16 to move, so that the three lifting plates 1... The alternating lifting and lowering of the 6-axis causes unevenness on the surface of the conveyor plate 2, increasing the vibration intensity during the seed descent and allowing impurities and dust on the seed surface to be better removed. The seeds then roll between the detector 7 and the nozzle 8, where the detector 7 performs color sorting detection on the seeds. In conjunction with the nozzle 8, high-pressure air is sprayed onto abnormal seeds, blowing them onto the screening plate 9. Normal seeds continue to fall along the bottom surface of the color sorting chamber 1. Finally, the seeds in different conditions are discharged through the first discharge port 10 and the second discharge port 11.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.
