DETAILED DESCRIPTION

[0020] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods, but the protection scope and application scope of the present invention are not limited.

[0021] Embodiment: A multi-stage screening device for corn seed processing, such as Figure 1-Figure 4 As shown, it includes an outer shell 1, supporting legs 11, an upper hopper 12 and a cover plate 13. The outer shell 1 is a square shell with an opening on the front side. Four supporting legs 11 are welded and fixed at intervals on the bottom of the outer shell 1. An upper hopper 12 is welded and fixed on the left side of the top of the outer shell 1. The upper hopper 12 is connected to the internal space of the outer shell 1. A cover plate 13 is detachably installed on the front side of the outer shell 1 by bolts. It also includes a screening component and a dust removal component. A screening component for grading and screening corn is arranged in the outer shell 1, and a dust removal component for processing dust is commonly arranged on the outer shell 1 and the screening component.

[0022] like Figure 2 , Figure 3 and Figure 4As shown, the screening assembly includes a fixed plate 21, a column 22, a cylinder 23, a buffer spring 24, a vibration motor 25, a mounting plate 26, a screen plate 27 and a blanking frame 28. The housing 1 is provided with a fixed plate 21, and four columns 22 are welded and fixed at intervals at the bottom of the fixed plate 21. The columns 22 are all slidably connected with cylinders 23. Buffer springs 24 are connected between the cylinders 23 and the fixed plate 21, and the buffer springs 24 are arranged on the outside of the columns 22. The bottom middle of the fixed plate 21 is fixed by bolts. A vibration motor 25 is installed, and three mounting plates 26 are welded and fixed at intervals on the front and rear sides of the fixing plate 21. Three sieve plates 27 are arranged on the mounting plates 26 from top to bottom. The three sieve plates 27 are arranged in an inclined manner so that the objects on the sieve plates 27 can roll to the right. A feed frame 28 is fixedly connected to the right side of the sieve plate 27 by bolts, and a hook for hanging a collection bag is welded and fixed on the top of the feed frame 28. The length of the feed frame 28 decreases from top to bottom, so that the collection bags do not affect each other.

[0023] like Figure 2 , Figure 3 and Figure 4 As shown, the dust removal assembly includes a dust collector 31, a mounting frame 32, a rotating shaft 33, a conveyor belt 34, a servo motor 35 and a scraper 36. The dust collector 31 is installed on the top right side of the shell 1, and the movable dust collection end of the dust collector 31 is connected to the upper panel that penetrates the shell 1 and is connected to the inside thereof. The mounting frame 32 is fixedly connected between the lower parts of the mounting plates 26 by bolts. The rotating shaft 33 is rotatably connected to the left and right sides of the mounting frame 32. A conveyor belt 34 is arranged between the two rotating shafts 33. The bottom of the conveyor belt 34 is in contact with the top of the fixed plate 21. A servo motor 35 is installed on the left side of the mounting frame 32 by bolts. The output shaft end of the servo motor 35 is fixedly connected to the end of the rotating shaft 33 on the left side by a coupling. A scraper 36 is welded and fixed on the left side of the mounting frame 32, and the scraper 36 is in contact with the bottom left side of the conveyor belt 34.

[0024] When using this embodiment, first connect the discharge port of the corn threshing device to the top of the upper hopper 12, and the corn cobs and corn kernels fall from the upper port onto the sieve plate 27 on the top layer. Then start the vacuum cleaner 31. Since the threshed corn first falls onto the sieve plate 27 on the top layer, more dust will be raised in the space above the sieve plate 27 on the top layer. At this time, the vacuum cleaner 31 can absorb and remove the raised dust. Then start the vibration motor 25 and the servo motor 35. The cylinder 23, the buffer spring 24 and the column 22 support the fixed plate 21 so that the fixed plate 21 can move up and down, thereby enabling the vibration motor 25 to pass through the fixed plate 21. The mounting plate 26 drives the three sieve plates 27 to vibrate up and down. The sieve plate 27 on the top layer screens out the corn cobs and drops them out from the unloading frame 28 set on its right side. The sieve plate 27 on the middle layer screens out the corn kernels with full particles. The sieve plate 27 on the bottom layer screens out the broken corn kernels. The dust finally falls on the conveyor belt 34. The servo motor 35 drives the conveyor belt 34 to rotate through the rotating shaft 33, so as to transport the dust dropped and adsorbed on the top of the conveyor belt 34 to the outer side of the left part of the shell 1. Under the scraping action of the scraper 36, the dust is scraped off the conveyor belt 34 and falls on the ground for centralized collection.

[0025] like Figure 3 As shown, it also includes an installation frame 41 and a collection frame 42. The installation frame 41 is welded and fixed on the left side of the lower part of the shell 1, and the collection frame 42 is slidably placed on the top of the installation frame 41.

[0026] By providing the installation frame 41 and the collection frame 42, the dust scraped off from the conveyor belt 34 can be collected, so that the dust can be processed later.

[0027] like Figure 3 As shown, a dust suppression water pipe 43 is also included. The dust suppression water pipe 43 is fixedly connected to the lower side of the inner wall of the rear panel of the outer shell 1. A plurality of atomizing nozzles are arranged on the dust suppression water pipe 43. The dust suppression water pipe 43 is inclined, and its inclination angle is consistent with the sieve plate 27. The rear end of the dust suppression water pipe 43 passes through the rear panel of the outer shell 1 and is connected to an external water supply device.

[0028] By setting up the dust suppression water pipe 43, a small amount of dust floating in the air is adsorbed by water mist and falls on the conveyor belt 43, so that the dust on the conveyor belt 43 is adhered, thereby preventing dust from being generated during scraping.

[0029] like Figure 3 As shown, a static eliminator 5 is also included, and the static eliminator 5 is installed on the left side of the housing 1 by bolts.

[0030] By providing the static eliminator 5, static electricity on the housing 1 and the cover plate 13 is eliminated to prevent dust from being adsorbed on the inner wall of the housing 1 and the cover plate 13 due to static electricity, causing trouble for later cleaning.

[0031] like Figure 1 As shown, an observation plate 6 is also included. A plurality of observation plates 6 are arranged on the cover plate 13 . The observation plates 6 are arranged in an inclined manner, and the inclination angle thereof is consistent with that of the sieve plate 27 .

[0032] The observation plate 6 is provided to facilitate the staff to observe the working status of each sieve plate 27 in real time.

[0033] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
