[0054] The working principle and use process of the present application are as follows: first, the sampling sample grain to be detected is sent into the crushing box 602, then the crushing motor 605 is started to drive the crushing roller 604 to rotate, and at the same time, the power is transmitted through the cooperation of the two power transmission gears 606, so that the two crushing rollers 604 are forced to rotate synchronously, and the grain is crushed into equal-sized fragments;

[0055] In addition, during crushing, the vibration traction plate 612 is moved by the cooperation of the power transmission gear 606 and the rotating traction disc 611, thereby driving the vibration connecting plate 610, the reciprocating lifting slide 608 and the separation sieve 609 to move up and down along the vibration limiting groove 607, so as to screen the crushed grain, so that the grain with too large size is discharged and collected through the material collecting box 603, and the grain with smaller size passes through the separation sieve 609 and is discharged from the crushing box 602 for subsequent detection;

[0056] Then, the adjusting tooth ring 517 is rotated to drive the driven tooth ring 516 and the traction rotating drum 515 to rotate, so as to slide the traction pull rod 518, the splicing piece 519 and the lifting extension cylinder 506, adjust the length of the connection between the material receiving sleeve 505 and the lifting extension cylinder 506 according to the need, change the storage amount of the grain, in addition, the height adjusting rod 508 drives the lifting pull plate 509, the load supporting plate 510 and the weighing controller 520 to move upwards, so that the top end of the weighing controller 520 is in close contact with the bottom end of the lifting extension cylinder 506, the gap is reduced, the grain fragments are prevented from spilling out, and the storage effect is maintained;

[0057] Then, when the broken grain crumbs of equal volume pass through the moving blocking platform 504 into the receiving sleeve 505 and the lifting extension cylinder 506, they are stored, and the weight of the grain crumbs is recorded at any time by the weighing controller 520 during storage. When the grain crumbs in the receiving sleeve 505 and the lifting extension cylinder 506 are full and the weight meets the requirements, the weighing controller 520 controls the forward and reverse circulation motor 503 to rotate forward, and through the cooperation of the transmission sprocket 511 and the transmission chain 512, the two material conveying levers 502 rotate together, moving the moving blocking platform 504, the receiving sleeve 505 and the lifting extension cylinder 506, so that the lifting extension cylinder 506 moves out of the top end of the load bearing plate 510, and at the same time, the measured grain crumbs are pushed down from the weighing controller 520 and fall on the grain conveying belt 3 for conveying.

[0058] During the pushing process, the movement of the moving blocking platform 504 can seal the bottom end of the crushing box 602 to prevent grain from spilling outside and reduce waste.
