[0026] It also contains:

[0027] A screening frame 4, wherein the screening frame 4 is screwed together in the screening box 2 through a shaft and a bearing, and the screening frame 4 is tilted downward on the left side, and a dividing plate 14 is fixedly provided on the inner top wall of the screening box 2 by bolts, and the dividing plate 14 is located below the feed hopper 3, and the pumpkin seeds dropped from the feed hopper 3 can be distributed on the screening frame 4 more dispersedly through the dividing plate 14, so as to avoid a large amount of accumulation of pumpkin seeds at a certain position of the screening frame 4, and a driving rod is fixedly provided on the right side of the screening frame 4, and the driving rod is movably provided in a strip-shaped through groove provided on the right side wall of the screening box 2, and a screening specification adjustment mechanism 5 connected with the driving rod is provided on the screening frame 4;

[0028] A motor 6, which is fixedly mounted on the upper right side of the processing body 1 by bolts, and is electrically connected to an external power supply. A drive disk 7 is fixedly mounted on the output shaft of the motor 6, and a No. 1 connecting rod 8 is screwed on the drive disk 7 through a shaft and a bearing;

[0029] A second connecting rod 9, wherein the second connecting rod 9 is hingedly arranged at the lower end of the first connecting rod 8, and the lower end of the second connecting rod 9 is screwed to the driving rod through a joint bearing;

[0030] A material guide plate 10 is provided in the screening box 2 by bolts and tilted downward on the right side. A fan unit 11 is provided at the opening of the left wall of the screening box 2 by bolts. The fan unit 11 is electrically connected to an external power supply. A storage box 12 is provided at the opening of the right wall of the screening box 2. The right side of the material guide plate 10 is located in the storage box 12. A cleaning box 15 is movably provided in the storage box 12. The cleaning box 15 can be taken out of the storage box 12 to facilitate pouring out and cleaning the collected bad seeds.

[0031] The screening specification adjustment mechanism 5 comprises:

[0032] A screening plate 5-1, wherein the screening plate 5-1 is movably disposed in a movable groove at the bottom of the screening frame 4, and a screening hole corresponding to the screening frame 4 is disposed on the screening plate 5-1, and sliding bars 5-2 are fixedly disposed on both the front and rear side walls of the screening plate 5-1 by bolts, and the sliding bars 5-2 are slidably disposed in a sliding groove disposed on the inner side wall of the movable groove;

[0033] A threaded rod 5-3 is provided in the driving rod through a bearing screw connection, one end of the threaded rod 5-3 is screwed into the screening plate 5-1 through a threaded screw connection, and an adjusting handle 5-4 is fixedly provided on the right end of the threaded rod 5-3 by a bolt. A protective shell 13 is screwed on the right side wall of the screening box 2 through a hinge, and the protective shell 13 covers the driving disk 7, the No. 1 connecting rod 8, the No. 2 connecting rod 9 and the adjusting handle 5-4. The protective shell 13 can not only provide protection for the driving disk 7, the No. 1 connecting rod 8, the No. 2 connecting rod 9 and the adjusting handle 5-4, but also prevent personnel from accidentally touching the driving disk 7, the No. 1 connecting rod 8, the No. 2 connecting rod 9 and the adjusting handle 5-4 during the driving process and causing injuries.

[0034] When using the utility model, pumpkin seeds are poured into the screening box 2 through the feed hopper 3, so that the pumpkin seeds fall onto the screening rack 4, and then the motor 6 is started, and the motor 6 drives the driving disk 7 to rotate. The driving disk 7 cooperates with the first connecting rod 8 and the second connecting rod 9, so that the driving rod can drive the screening rack 4 to swing back and forth with the rotation point with the screening box 2 as the center of the circle. At this time, the seeds on the screening rack 4 will vibrate and move slowly to the left. In this process, smaller seeds will fall onto the guide plate 10 through the screening holes on the screening rack 4 and the screening plate 5-1. When the seeds with qualified volume move to the left side of the screening rack 4 and fall downward, the wind blown out by the fan unit 11 can blow the hollow seeds therein to the guide plate 10, and the small or hollow unqualified seeds dropped from the guide plate 10 will move to the right side to the cleaning box 15 in the storage box 12. When it is necessary to clean the seeds in the cleaning box 15, the box cover of the storage box 12 can be flipped open, and then the cleaning box 15 can be taken out to clean the seeds in the cleaning box 15. The seeds that normally fall from the screening rack 4 will fall into the processing body 1 for processing;

[0035] When it is necessary to adjust the specification standard for seed size screening, the protective shell 13 can be flipped over, and then the adjustment handle 5-4 can be turned. The adjustment handle 5-4 drives the threaded rod 5-3 to rotate, so that the screening plate 5-1 moves in the movable groove through the guidance of the sliding bar 5-2, thereby realizing the adjustment of the size of the screening holes that are connected on the screening frame 4 and the screening plate 5-1, thereby realizing the adjustment of the specification standard for seed size screening.

[0036] After adopting the above structure, the beneficial effects of this specific implementation are as follows:

[0037] 1. Through the cooperation of the screening rack 4, the motor 6, the driving disk 7, the No. 1 connecting rod 8, the No. 2 connecting rod 9, the guide plate 10, the fan unit 11 and the storage box 12, the smaller or empty seeds can be screened out before the seeds are processed, thereby improving the processing quality of the seeds;

[0038] 2. Through the cooperation of the screening specification adjustment mechanism 5, the screening standard of seed size can be adjusted according to demand.

[0039] For those skilled in the art, they can modify the technical solutions recorded in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
