[0021] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0022] like Figure 1 As shown, it is a schematic diagram of the structure of the seed production impurity removal cleaning screen of the utility model. The cleaning screen of the utility model is provided with a screening device 10 and a feeding device 20. The screening device 10 is provided with a support frame 11, a driving device 12, a transmission device 13 and a vibrating screen. The vibrating screen is provided with a screen 14 and a bottom material plate 15 arranged in sequence from top to bottom. A feed plate 141 is provided at one end of the screen 14, and a first discharge port 142 is provided at the other end. The height of the feed plate 141 is greater than the height of the first discharge port 142. One end of the feed plate 141 is connected to the screen 14, and a support rod 30 is provided on the lower bottom surface of the other end. The upper end of the support rod 30 is movably connected to the bottom surface of the feed plate 141. Strip baffles are provided on both sides of the feed plate 141 and the screen 14. During use, the seed raw material is lifted onto the feed plate 141. Since the screen 14 is inclined, the seed raw material enters the screen 14 from the feed plate 141. The driving device 12 of the utility model can be a motor (such as Figure 1 As shown in the figure, the motor is fixed on the support frame 11 and is located below the vibrating screen. The transmission device 13 is connected to the motor and the vibrating screen respectively. The output shaft of the driving device 12 is connected to the transmission device 13 through a conveyor belt. After starting the driving device 12, the transmission device 13 immediately starts a small reciprocating motion, and at the same time drives the structure of the vibrating screen to vibrate, wherein a second discharge port 151 is provided at the outer end of the bottom material plate 15. During the repeated vibration of the vibrating screen, the screen 14 removes impurities and screens the seed raw materials, and the impurities that have not been screened are discharged through the first discharge port 142, while the seeds that pass through the screen 14 enter the bottom material plate 15 and are finally discharged through the second discharge port 151.

[0023] Please also see Figure 1 and Figure 2As shown, the loading device 20 of the utility model is located on the side of the feed plate 141 of the screening device 10, and the loading device 20 is provided with a mounting plate 21, two support columns 22, a flip plate, two cylinders 24, two first connecting rods 25 and two second connecting rods 26. The mounting plate 21 and the support frame 11 are fixed on the same plane, and the support columns 22 are respectively vertically arranged at adjacent top corners of the upper surface of the mounting plate 21. The flip plate can be rotated at an angle of at least 90 degrees from bottom to top under the action of the cylinder 24 and the first connecting rod 25 and the second connecting rod 26.

[0024] Specifically, a reinforcing plate 27 is provided on the inner side of the right angle formed by the support column 22 and the mounting plate 21, and a mounting plate 28 is provided at the bottom of the cylinder 24. The mounting plate 28 is fixed to the reinforcing plate 27 by bolts. The outer end of the piston rod 241 at the upper end of the cylinder 24 is connected to the other parts of the first connecting rod 25 except the two ends, and the connection position with the first connecting rod 25 is set according to the actual situation, so that the flip plate can be rotated at an angle of at least 90 degrees from bottom to top.

[0025] Please continue reading Figure 2 As shown, the first connecting rod 25 is located below the second connecting rod 26, and the inner side surface of the support column 22 is provided with a first positioning plate 221 and a second positioning plate 222 in sequence from bottom to top, and the flip plate is provided with a bottom plate 231 and a baffle 232. The bottom plate 231 and the baffle 232 form an L shape, and the two are integrally formed. One end of the first connecting rod 25 is rotatably connected to the first positioning plate 221, and the other end is rotatably connected to the side of the baffle 232. One end of the second connecting rod 26 is rotatably connected to the second positioning plate 222, and the other end is rotatably connected to the side of the baffle 232. The "rotatable connection" here can be achieved by setting a through hole between the two connected parts, and setting a bolt structure in the through hole, thereby realizing a rotatable connection between the two parts, or other structures that also realize a rotatable connection are also possible, but are not limited to this.

[0026] The ultimate purpose of the utility model is to realize that after the flip plate completes the maximum angle rotation under the action of the cylinder 24, the first connecting rod 25 and the second connecting rod 26, the baffle 232 abuts against the feed plate 141. The specific working principle and operation steps are as follows: When the feeding device 20 of the utility model is in the initial state, that is, Figure 1In the state shown in the figure, the bottom plate 231 overlaps with the mounting plate 21, and then the staff places the packaging bag containing the seed raw material on the bottom plate 231, so that the opening of the packaging bag faces the outside of the bottom plate 231, and then starts the two cylinders 24 to drive the piston rod 241 to start moving outward. At the same time, the first connecting rod 25 connected to the outer end of the piston rod 241 starts to rotate, and at the same time drives the baffle 232 to flip in the direction away from the bottom plate 231. During the flipping process, the bottom plate 231 and the baffle 232 not only rotate, but also move upward. The baffle plate 232 is moved, and finally the outer edge of the baffle plate 232 is flipped 90 degrees, and the outer edge of the baffle plate 232 is against the outer edge of the feed plate 141. After the above process, the packaging belt containing the seed raw material also achieves a height increase and an angle rotation along with the flip plate. At this time, the opening of the packaging bag is facing a direction perpendicular to the feed plate 141. Finally, the packaging bag is turned over to allow the seeds to enter the vibrating screen at a uniform speed through the feed plate 141. The above whole process only requires one person to complete the operation, which saves time and effort, and can also ensure the feeding speed and improve the screening and impurity removal efficiency.

[0027] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
