DETAILED DESCRIPTION

[0027] like Figure 1-5A popcorn rapid screening device is provided, comprising a second conveyor belt unit 2, a screening frame 3 and a first conveyor belt unit 1 arranged from high to low, the screening frame 3 comprising a bottom plate 301, both sides of the bottom plate 301 are overlapped with the first conveyor belt unit 1 and the second conveyor belt unit 2 respectively, a plurality of sieve holes 302 are arranged in the middle of the bottom plate 301, a material drop opening 306 is arranged at the lower part of the bottom plate 301, and the material drop opening 306 is arranged opposite to the sieve holes 302, the bottom plate 301 is connected to the ground through a supporting unit 4, and a vibrator 5 is detachably provided at the bottom of the bottom plate 301. The first conveyor belt unit 1 and the second conveyor belt unit 2 have the same structure and differ only in height, so that the overall production is more convenient and the cost is lower. The bottom plate 301 of the screening frame 3 is located at the edge of its conveyor belt and slightly lower than its rotation center, close to the side of the second conveyor belt unit 2 which is relatively high, so as to better receive the popcorn from the second conveyor belt unit 2. Since the bottom plate 301 is inclined, the bottom plate 301 will not interfere with the edge of the conveyor belt of the second conveyor belt unit 2. At the same time, the side of the bottom plate 301 which is close to the first conveyor belt unit 1 which is relatively low is overlapped on the top plane of the first conveyor belt unit 1, so that the screened popcorn is transmitted to the first conveyor belt unit 1. The overall screening and transportation cycle is shorter, and the screening process is easier to manage. When the unqualified corn kernels pass through the sieve hole 302, they enter the storage bag below through the drop port 306, which is convenient for the staff to carry out subsequent processing. The storage bag is detachably arranged below the drop port.

[0028] like Figure 6-7 In the preferred solution, side plates 309 are provided on both sides of the bottom plate 301, and the side plates 309 are connected to the bottom plate 301 through guide plates 303, and the guide plates 303 are used to guide the popcorn to the sieve holes 302. With this structure, the overall screening efficiency is high while ensuring the structural strength of the bottom plate 301, and all popcorn can be guided to the sieve holes 302 through the guide plates 303, avoiding the problem of popcorn escaping.

[0029] In a preferred solution, the guide plate 303 includes a straight portion 304, which is arranged at the edge of the outermost sieve hole 302, and inclined portions 305 are arranged on both sides of the straight portion 304.

[0030] In a preferred embodiment, the inner size of the drop opening 306 is larger than the coverage area of ​​the sieve hole 302. With this structure, the overall storage effect of popcorn is better. The popcorn is produced at high temperature and has a grease-covered surface, which avoids the problem that the popcorn splashes and slides and is adsorbed on the inner wall of the drop opening 306 due to its own weight and speed when passing through the sieve hole 302.

[0031] In a preferred solution, the straight portion 304 and the side plate 309 are connected by a rib plate 308. With this structure, the overall structural strength is improved.

[0033] In a preferred solution, a plurality of through holes 410 are provided on the frame 401, and the straight rod 404 is located in the through holes 410, and the straight rod 404 is connected to the frame 401 through a locking ring 406. With this structure, the overall vibration direction is unified, and the overall screening effect is good. The locking ring 406 and the straight rod 404 are threadedly connected, and the position of the locking ring 406 can be adjusted to change the amplitude of the vibration.

[0034] In a preferred solution, a plurality of threaded holes 307 are provided along the circumferential direction at the bottom of the bottom plate 301, and the straight rods 404 are threadedly connected to the threaded holes 307. This structure makes installation and disassembly convenient and has a good fixing effect.

[0035] In the preferred solution, a plurality of hinge seats 407 are provided along the circumferential direction at the lower part of the frame 401, a lug plate 408 is provided at the upper part of the sleeve 402, the lug plate 408 is connected to the hinge seat 407 via a shaft 409, and the sleeve 402 is threadedly connected to the adjustment rod 403. With this structure, the adjustment is flexible, and the angle of the bottom plate 301 can be changed by changing the height of the sleeve 402 to meet the needs of use, and the position of the sleeve 402 can be adjusted so that the plurality of sleeves 402 cooperate to adjust the tilt angle of the frame 401, and the adjustment range is large.
