When in use, in order to ensure the stable operation of the screening frame 3, a certain height difference is maintained between the top surfaces of the conveyor belts of the first conveyor belt unit 1 and the second conveyor belt unit 2. The C-shaped plate 301 serves as an inclined surface, which can screen the popcorn from the upper side through the sieve hole 302. At the same time, under the action of the vibrator 8, the screening efficiency is maintained. By rotating the locking sleeve 903 on the jacking unit 9, the height of the cantilever plate 901 is changed, and the height of the second supporting legs 903 on both sides is adjusted, thereby completing the overall jacking of the second conveyor belt unit 2. It is easy to operate, has a large adjustment range, and has a good use effect.

[0030] like Figure 7-8 In the preferred solution, the adjustment frame 5 includes a frame 501, the frame 501 and the C-shaped plate 301 are detachably connected, the lower part of the frame 501 is hinged with a plurality of sleeves 502, the lower part of the sleeve 502 is telescopically provided with a first threaded rod 503, and the first threaded rod 503 is respectively connected to the first conveyor belt unit 1 and the telescopic support unit 4 through the fixing plate 6. The first threaded rod 503 and the sleeve 502 are threadedly connected, so that the position of the sleeve 502 can be changed by adjusting the first threaded rod 503 to meet the change of the state of the frame 501, and the fixing plate 6 can be used to apply force to fix the first conveyor belt unit 1 and the second conveyor belt unit 2 during the adjustment of the adjustment frame 5. Since the first conveyor belt unit 1 and the second conveyor belt unit 2 have large volumes and heavy weights, their own states are stable. Through the cooperation of the fixing plate 6, it is ensured that the adjustment frame 5 is only fine-tuned in the transportation direction and the height direction, the overall installation accuracy is good, and the screening effect is better. After the adjustment is completed, the fixing plate 6 is used to complete the complete locking of the adjustment frame 5 itself to ensure the overall structural rigidity.

The guide plate 304 and the C-shaped plate 301 are connected to form a structure with large ends and a small middle part, thereby ensuring the screening effect of popcorn. All popcorn from above is gathered at the sieve hole 302 to complete the screening. After the screening is completed, it is avoided to accumulate at a low place, and the circulation efficiency is better.

[0037] In the preferred solution, a plurality of straight rods 307 are provided on the lower side of the C-shaped plate 301, a plurality of third through holes 504 are penetrated on the frame 501, the straight rods 307 are inserted into the third through holes 504, a spring 308 is sleeved on the straight rods 307, and the straight rods 307 are connected to the frame 501 through a locking ring 309. With this structure, the overall screening effect of the C-shaped plate 301 is better. Under the action of the vibrator 8, the C-shaped plate 301 moves slightly up and down in the direction perpendicular to the frame 501, so that the popcorn can pass through the sieve hole 302 stably and quickly, and at the same time, it can also provide buffer to ensure the stability of the structure.
