The fan 5 can carry out preliminary dust removal of sweeping to the grain on the conveyer belt 7, and the wind-force that fan 5 blew out can blow away light impurity, but is not enough to blow away grain, and heavy impurity need carry out the edulcoration through screen cloth 11 and the filter screen 10 in the sieving mechanism again.

A plurality of universal wheels 41 are fixedly arranged on one side of the bottom surface of the bottom frame 4 close to the collecting cylinder 1; one side of the bottom surface of the bottom frame 4 close to the weighing device 8 is fixedly provided with a plurality of travelling wheels 43, the travelling wheels 43 are driven by a fourth motor 42 fixedly arranged on the top surface of the bottom frame 4, and the fourth motor 42 is electrically connected with a control unit 44.

When the multifunctional grain bag is used, the bolts in the two threaded holes 34 are unscrewed, the rotating beam 17 is rotated to a proper position to adapt to the size of a grain bag, then the bolts are screwed down to fix the position of the rotating beam 17, then the fastening knob 45 is unscrewed, the connecting rod 25 is rotated to enable the receiving frame 32 to be horizontal, and the fastening knob 45 is screwed down; manually plugging one end of an opening of a grain bag into the mending machine 36, starting the first motor 9, the second motor 13, the fourth motor 42 and the fan 5, driving the whole grain collecting machine to advance by the fourth motor 42, driving the driving shaft 20 to rotate by the first motor 9, driving the rotating shaft 24 to rotate by the driving shaft 20 through the conveyor belt 7, driving the packing auger 2 to rotate by the rotating shaft 24, collecting grains on the ground by the packing auger 2 and conveying the grains to the conveyor belt 7, driving the grains to move by the conveyor belt 7, blowing away light impurities on the grain surface by the fan 5 when passing through the fan 5, then enabling the grains to fall on the screen mesh 11 from the highest position of the conveyor belt 7, driving the rotating wheel 26 to rotate by the second motor 13, driving the driving rod 27 to reciprocate by the rotating wheel 26, driving the screen mesh 11 to shake so as to filter and remove impurities on the grains on the screen mesh 11, and intercepting large-particle impurities on the screen mesh 11, grain falls into the filter screen 10 through the screen cloth 11, the filter screen 10 also can slightly shake under the vibrations that second motor 13 self produced, thereby make grain carry out the secondary filter, less granule can be intercepted on the filter screen 10, grain through the filter screen 10 falls into the grain bag of placing on weighing device 8, when weight reaches the specified value, first motor 9, second motor 13, fourth motor 42 and fan 5 stop work, third motor 16 starts, screw 38 rotates, thereby drive mending machine 36 axial displacement, mending machine 36 work simultaneously and seal the grain bag, after sealing, third motor 16 stops work, after changing new grain bag, repeated same operation can carry out automatic receipts grain again.
