Wherein, pressure plate 2051 is through round axle connection in the rectangular form panel on displacement groove 205 middle part top, and connect the inner wall of round axle and connect through torsion spring in the bearing, make one side of its straw to support in one side of round axle 2042 because the straw makes along spout 2031's landing when round axle 2042 is rotatory, because the length of its straw can drive the straw through its friction and turn to one side through its friction in the great laminating of one side that exposes with round axle 2042 of volume drives the application of force through rotating, can let the straw carry out the application of force on pressure plate 2051 and let pressure plate 2051 incline to one side and let displacement groove 205 open its gap and let the straw fall and collect in the collecting vat 103 of main part 1 when carrying out the application of force.

The working principle is as follows:

the specific use mode and function of the embodiment are that firstly wheat is harvested by the wheat harvester, then the harvested wheat is conveyed to a designated area by the main body 1 to be discharged and stored through the discharge port 102, the harvested wheat can be conveyed and stored while being harvested so as to be convenient for the wheat to be transported, the wheat can enter the sieving cylinder 2 to be transported when being conveyed inside the main body 1 through pressurization of the wheat, the wheat firstly contacts the transmission block 2021 of the impact groove 202 when entering the sieving cylinder 2, the wheat can move along the arc surface through the curved arc surface of the transmission block 2021, the pressure generated in the movement can force the transmission block 2021 to force one side to drive the whole sieving cylinder 2 to rotate inside the main body 1, and the sieving cylinder 2 is not matched with the collecting groove through the mutual embedding of the rotating ring 201 and the limiting ring 104 when rotating 103 are mutually attached to each other to rotate and reduce the friction force thereof, meanwhile, the roller 2021 in the middle of the rotating ring 201 can enable the rotation to be smoother and not to be blocked, the position of the sieving cylinder 2 is limited and not to be deviated, then when the sieving cylinder 2 rotates, the wheat transmitted inside can be rolled, the wheat can pass through the surface of the chute 2031 on one side of the sieving block 203 during the rolling process, the semicircular annular bulge on one end is extended through the chute 2031 to block and limit the wheat straw contained in the wheat, the wheat straw is blocked in the bulge of the chute 2031, then the wheat straw screened out is enabled to slide down on the pressure plate 2051 of the displacement groove 205 on one side of the bottom end along the inclined surface of the chute 2031 to screen the wheat straw out through the change of the rotation angle of the sieving cylinder 2, finally, when the sieving cylinder 2 rotates, one side of the circular shaft 2042 in the collecting shaft 204 is protruded on the surface of the sieving cylinder 2 to be mutually embedded with the surface of the collecting groove 103, the round shaft 2042 is embedded with the groove marks on the surface of the inner wall of the collecting groove 103 to enable the round shaft 2042 to rotate when the sieving cylinder 2 moves, when the round shaft 2042 rotates, one side of wheat straws can abut against one side of the round shaft 2042 due to the fact that the wheat straws slide along the sliding groove 2031, because the wheat straws are completely attached to the exposed side of the round shaft 2042 in a large size, the wheat straws are driven to be driven to apply force to one side through the rotation of the wheat straws due to the friction of the wheat straws, when the force is applied, the wheat straws are applied to the pressure plate 2051, the pressure plate 2051 deflects to one side to enable the displacement groove 205 to open the gap of the wheat straws to fall into the collecting groove 103 of the main body 1 for collection, the wheat straws in the wheat are sieved and collected, and meanwhile, because the round shaft 2042 in the bundling shaft 204 only exposes one side, the wheat volume is small, so that the wheat straws cannot be rubbed to abut against the pressure surface to be driven to move Plate 2051 is biased so that it does not bias pressure plate 2051 when wheat falls onto pressure plate 2051.
