The lower end of the support roller rod 5 is fixedly connected with a weighing device 6, and the support roller rod 5 does not contact the chassis 1. The weight of the support roller rod 5 and the first screen frame 2 or the second screen frame 3 or the bottom frame 4 at its upper end will all act on the weighing device 6. The chassis 1 is provided with a cabinet door 12 at the front end, and an observation window is provided in the cabinet door 12. A display 13 is provided at the outer end of the cabinet door 12. The display 13 is connected to the weighing device 6 by a wire, so that the weighing value of the weighing device 6 will be displayed on the display 13, thereby facilitating the observation of the weight of the first screen frame 2, the second screen frame 3, and the bottom frame 4.

[0029] A gathering bucket 11 is provided at the lower end of the first sieve frame 2 and the second sieve frame 3 to prevent seeds from falling outside the second sieve frame 3 or the bottom frame 4.

[0030] Heating wires 7 are arranged on both sides of the chassis 1. The heating wires 7 can generate a large amount of heat when powered on. A feeding hopper 9 is arranged on the upper end of the chassis 1. A closing plate 10 is arranged in the feeding hopper 9. A supporting plate 22 is fixedly connected to the side end of the chassis 1. A bidirectional threaded rod 23 is connected in the supporting plate 22. The bidirectional threaded rod 23 is threadedly connected in the closing plate 10. A No. 2 motor 24 is fixedly connected to the side end of the supporting plate 22. The driving end of the No. 2 motor 24 is fixedly connected to the bidirectional threaded rod 23. Starting the No. 2 motor 24 can drive the bidirectional threaded rod 23 to rotate, thereby acting on the closing plate 10, so that the closing plate 10 moves into the feeding hopper 9 to close it, thereby preventing the heat generated by the heating wire 7 from overflowing from the feeding hopper 9.

[0032] Working principle: Pour all the seeds into the chassis 1 through the feed hopper 9, the seeds will accumulate in the first screen frame 2, and then start the No. 1 motor 19 to drive the disc 20 to rotate. The rotation of the disc 20 drives the slide bar 21 to move in the slide groove 18 of the connecting frame 17, thereby driving the connecting frame 17 to move, thereby driving the first screen frame 2 and the second screen frame 3 to move through the connecting rod 15 and the mounting tube 14, so that the two can make a reciprocating motion in the chassis 1, thereby shaking the seeds accumulated in the first screen frame 2, so that large-particle seeds can remain in the first screen frame 2, small-particle seeds can fall into the bottom frame 4 through the second screen frame 3, and seeds of normal size can remain in the second screen frame 3. After the screening is completed, start the No. 2 motor 24 to drive the two-way The threaded rod 23 rotates to act on the closing plate 10, thereby driving the closing plate 10 to move and seal the feed hopper 9. At this time, the reciprocating mechanism 8 is stopped, and the weight of the first sieve frame 2, the second sieve frame 3, and the bottom frame 4 is weighed by the weighing device 6 to obtain a first set of data, and then the heating wire 7 is started for heating to dry the seeds to remove the internal moisture. After drying, the weighing device 6 is used again to weigh the weight of the first sieve frame 2, the second sieve frame 3, and the bottom frame 4 to obtain a second set of data, subtracting the weight of the first sieve frame 2, the second sieve frame 3, and the bottom frame 4 themselves. The numerical difference between the two sets of corresponding data is the weight of the evaporated water of large-particle seeds, normal-sized seeds, and small-particle seeds, thereby obtaining the proportion of moisture contained in seeds of different sizes.
