DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to Figures 1-4 , the present utility model provides a technical solution: a screening device for grain processing that is convenient for feeding, including a box body 1. A plurality of elastic feet 2 are fixedly installed at the bottom of the box body 1, and a rubber pad 3 is fixedly installed at the bottom of the elastic feet 2. One end of the top of the box body 1 is fixedly sleeved with a branch pipe 8. The top end of the branch pipe 8 is fixedly installed with a feeding cone 11. A spiral plate 15 is fixedly installed inside the branch pipe 8. A pillar 14 is fixedly installed in the middle of the spiral plate 15. The top of the pillar 14 is fixedly installed with a hollow cone 10. The bottom end of the branch pipe 8 is fixedly installed with a limiting cone 16. Four support rods 9 are fixedly installed on the outside of the feeding cone 11. A connecting pipe 5 is communicated inside the feeding cone 11. One side of the connecting pipe 5 is communicated with a lead-out pipe 6. The end of the connecting pipe 5 away from the feeding cone 11 is fixedly installed with a gas guiding cone 17. The other end of the lead-out pipe 6 is communicated with a dust filter 7. The bottom of the dust filter 7 is communicated with a corrugated pipe 13. The top of the inner cavity of the box body 1 is hinged with a first elastic telescopic column 21. The bottom of the first elastic telescopic column 21 is hinged with a first sieve plate 18. The bottom of the other end of the first sieve plate 18 is hinged with a third elastic telescopic column 23. The bottom of the third elastic telescopic column 23 is hinged with a second sieve plate 19. The bottom of the other end of the second sieve plate 19 is hinged with a second elastic telescopic column 22. The bottom of the second elastic telescopic column 22 is hinged with a third sieve plate 20. Two first discharge ports 4 are opened at one end of the box body 1. A second discharge port 12 is opened at the other end of the box body 1. A plurality of blanking holes 24 are opened at the bottom of the box body 1. A vibrator 25 is fixedly installed at the bottom of the box body 1.
[0020] Working principle of the above technical solution: During use, the operator extracts the air flow of the dust filter 7 through the bellows 13 connected to the air pump. Then, the grain output pipeline is placed on the top of the feeding cone 11, and the grain conveyor and the vibrator 25 are turned on. At this time, the grain enters the inside of the branch pipe 8 through the diversion of the hollow cone 10 and the feeding cone 11. The grain enters the box body 1 under the spiral guidance of the spiral plate 15 inside the branch pipe 8, and the grain can be dispersed under the action of the spiral conveyor and the limiting cone 16. The grain falls on the top of the first sieve plate 18. At this time, one end of the first sieve plate 18 is elastically supported by the first elastic telescopic column 21 and shakes, causing the grain smaller than the sieve holes to fall on the top of the second sieve plate 19. The grain that meets the sieve holes passes through the diversion of the first sieve plate 18 and is collected through the first discharge port 4. The sieve holes of the first sieve plate 18, the second sieve plate 19, and the third sieve plate 20 are evenly distributed from large to small, facilitating efficient screening. This solution can effectively feed and screen, with high overall efficiency and convenient operation.
[0021] In another embodiment, as Figures 1-3 shown, the elastic feet 2 are linearly symmetrically and evenly distributed at the bottom of the box body 1.
[0022] The elastic feet 2 can enable the box body 1 to have elastic displacement and support under the action of the vibrator 25, and the overall structure is stable.
[0023] In another embodiment, as Figures 1-3 shown, the bottom end of the branch pipe 8 and the limiting cone 16 are both located at the top of the inner cavity of the box body 1, and the bottom ends of the four support rods 9 are fixedly installed on the top of the box body 1.
[0024] The branch pipe 8 and the limiting cone 16 facilitate the diversion and feeding of the grain, and the support rods 9 increase the structural strength at the top and stabilize the operation.
[0025] In another embodiment, as Figure 3 and Figure 4 shown, one end of the first sieve plate 18 is slidably installed inside the box body 1, one end of the first sieve plate 18 away from the first elastic telescopic column 21 is hinged inside the box body 1, one end of the second sieve plate 19 is slidably installed inside the box body 1, one end of the second sieve plate 19 away from the third elastic telescopic column 23 is hinged inside the box body 1, one end of the third sieve plate 20 is slidably installed inside the box body 1, one end of the third sieve plate 20 away from the second elastic telescopic column 22 is hinged inside the box body 1. The first sieve plate 18, the second sieve plate 19, and the third sieve plate 20 are distributed in a zigzag inclined shape inside the box body 1. The inclined ends of the first sieve plate 18 and the third sieve plate 20 correspond to the position of the first discharge port 4, and the inclined end of the second sieve plate 19 corresponds to the position of the second discharge port 12.
[0026] Grain is scattered on the top of the first sieve plate 18. At this time, the first sieve plate 18 is vibrated at one end and is supported by the elastic force of the first elastic telescopic column 21, so that the grain smaller than the sieve hole falls on the top of the second sieve plate 19. The grain that meets the sieve hole passes through the diversion of the first sieve plate 18 and is discharged and collected through the first discharge port 4. The operation mode of the second sieve plate 19 and the third sieve plate 20 is the same as that of the first sieve plate 18. The zigzag distribution can increase the flow distance of the grain and increase the contact time between the grain and the sieve plate, which is convenient for stable screening during the flowing grain screening operation and improves efficiency. The sieve holes of the first sieve plate 18, the second sieve plate 19 and the third sieve plate 20 are evenly distributed from large to small, which is convenient for efficient screening. This scheme can effectively feed and screen, with high overall efficiency and easy operation.
[0027] In another embodiment, Figures 1-3 As shown, the end of the connecting pipe 5 away from the feed cone 11 and the air guide cone 17 are located at the top of the inner cavity of the box body 1, the dust filter 7 is fixedly installed on the back of the box body 1, and the outlet pipe 6 is connected to the top of the dust filter 7.
[0028] By setting up the dust filter 7 and the connecting pipe 5, when the bellows 13 is connected to the air pump to draw air, the dust raised from the inside of the feed cone 11 and the inside of the box 1 can be drawn out with the airflow and discharged after being filtered by the dust filter 7, which helps to reduce the flying of dust, increases the safety of the working site environment, and protects the health of the workers.
[0029] In another embodiment, Figure 3 As shown, the discharge holes 24 are rectangular and evenly distributed at the bottom of the box body 1 , and the specifications and dimensions of the discharge holes 24 are adapted to the specifications and dimensions of the third sieve plate 20 .
[0030] The function of the discharge hole 24 is to discharge smaller particles such as soil particles and gravel, and to facilitate the discharge of the particles when the interior is flushed with water, thereby facilitating the cleaning operation.
[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
