When scraper plate 12 rotates forward (diagram L1 to) around the first vertical axis S1, scraper plate 12 can loose poor layer, carry out ploughing grain；When pivoted frame 11 drives
When scraper plate 12 inverts (diagram L2 to) around the first vertical axis S1, the wheat grain in lautertuns 100 can be released poor door by scraper plate 12, into
Row row's grain.It is clockwise forward rotation direction in the present embodiment, is counterclockwise reverse directions.However, the present invention is not limited thereto,
In another embodiment, it is counterclockwise forward rotation direction, is clockwise reverse directions.In the present embodiment, scraper plate system
System 1 further includes swing mechanism, and the rotating shaft of swing mechanism is the first vertical axis S1.The driving method of swing mechanism does not limit
It is fixed, it can be driven, can also be driven by hydraulic motor by motor-speed reducer system.
In the present embodiment, the first vertical axis S1 is overlapped with the central axes of lautertuns 100, in other embodiments, first
Vertical axis S1 can be with the axis parallel of lautertuns 100.
Further, the quantity of scraper plate 12 is to be at least 1, and scraper plate 12 extends along the vertical direction, in this way, scraper plate 12 exists
During rotating with pivoted frame 11, scraping plate face can push the wheat in accommodating chamber 100a poor.In the present invention, scraper plate 12 can be with respect to pivoted frame
11 around the second vertical axis S2 forward or reverse, here, the meaning of " rotating forward " and " reversion " is same as above, it will be understood that
In the present embodiment, just switch to rotate clockwise, is reversed to rotate counterclockwise.That is, in the present invention, scraper plate 12 is except can be around the
Outside one vertical axis S1 is revolved, also rotation can be carried out around the second vertical axis S2.
Specifically, with reference to Fig. 2 a~Fig. 3 b, in the present embodiment, scraper plate 12 is connected to the lower section of pivoted frame 11 by shaft 15,
Wherein, the axis of shaft 15 is the second vertical axis S2.It is rotatablely connected between shaft 15 and pivoted frame 11, scraper plate 12 and shaft 15
Between be fixedly connected so that scraper plate 12 can relative to the pivoted frame 11 around the second vertical axis rotate.In one embodiment, axis
It is connected between bar 15 and pivoted frame 11 by bearing, the second vertical axis S2 is the rotating shaft of bearing.In other embodiments, it scrapes
Plate 12 can also be used other modes and be connected with pivoted frame 11, for example, scraper plate 12 is connect with shaft 15 by bearing, and shaft 15 with turn
It is fixedly connected between frame 11；Or be between scraper plate 12 and pivoted frame 11 directly by bearing connect, as long as be able to achieve scraper plate 12 with
Relative rotation between pivoted frame 11.
The definition plane that by the first vertical axis S1 and radially (diagram R to) extends is the first plane P1, and first
Plane P1 is rotated synchronously with pivoted frame 11, wherein pivoted frame 11 is located in the first plane P1.In the present embodiment, pivoted frame 11 be one end with
The crossbeam of swing mechanism connection, and pivoted frame 11 extends along the radial direction (above-mentioned R to) of swing mechanism.It has been found that working as scraper plate 12
When angle α between the first plane P1 is 35~55 °, especially 40~45 °, the row's grain with higher of scraping plates system 1 effect
Rate.This is because such as wheat grain to be pushed to be discharged from poor door, scraper plate 12 push wheat grain circumferentially (diagram D to) advance it is same
When, it also needs have enough radial thrusts to wheat grain, wheat grain could be pushed to periphery from the center of lautertuns 100, further will
Wheat grain is released from poor door.If angle between scraper plate 12 and the first plane P1 is greater than above-mentioned angle, scraper plate 12 substantially with circumferential direction
Tangent, the main function of scraper plate 12 is to cut poor layer, and can not generate enough radial thrusts to poor layer；If scraper plate 12 and
When angle between one plane P1 is less than above-mentioned angle, scraper plate 12 substantially with it is radial parallel, main function is to push wheat grain edge
Week marches forward, and can not also generate enough radial thrusts.
It should be noted that " angle " that opposite first plane P1 is rotated forward is positive value in the present invention, opposite first is flat
Face P1 counter-rotational " angle " is negative value.That is, the angle of scraper plate 12 and the first plane P1 be 35~55 ° (or 40~
45 °), indicate that scraper plate 12 rotates forward 35~55 ° (or 40~45 °) with respect to the first plane P1.
For ease of description, present invention introduces term " arranging poor plane ", during arranging grain, if scraper plate 12 may remain in

It is freely rotated around the second vertical axis S2, therefore, for the prior art during arranging grain, scraper plate 12 is relative to the first plane P1's
Angle is not fixed and invariable.Specifically, the practical angle between scraper plate 12 and the first plane P1 is hindered by centrifugal force and wheat grain
What power codetermined, as shown in Figure 2 b, centrifugal force has the trend (even if angle increase trend) for rotating forward scraper plate 12, and wheat
Poor resistance has the trend (even if trend that angle reduces) for inverting scraper plate 12.It is appreciated that in the initial stage of row's grain, wheat
Poor thickness is big, also big to the resistance of scraper plate 12, and wheat grain pushes scraper plate 12 to invert, at this point, between scraper plate 12 and the first plane P1
Angle is smaller；With the progress for arranging poor process, when wheat grain thickness is thinning, wheat grain reduces the resistance of scraper plate 12, and scraper plate 12 exists
Under the action of centrifugation, the angle between the first plane P1 can become larger (it is appreciated that when not having wheat grain, in the work of centrifugal force
Under, scraper plate 12 is finally vertical with the first plane P1).When angle is greater than the poor angle of effectively row between scraper plate 12 and the first plane P1
When (i.e. 35~55 °), wheat grain cannot be fully drained, and having wheat grain can remain in lautertuns 100.

That is during arranging grain, if centrifugal force effect is greater than drag effect, so that the folder between scraper plate 12 and the first plane P1
When angle is greater than effectively row's grain angle (when scraper plate 12 is detached from row grain plane P3), under the power-assisted effect of magnetic attracting device 13, it can promote
It rotates backward scraper plate 12 and makes in the poor plane P3 of 12 row of being eventually held in of scraper plate, so that scraper plate 12 is during arranging grain,
It is always positioned at and effectively arranges poor angle, so that thoroughly row's grain can be realized.In the present embodiment, when scraper plate turn to arrange poor plane P3 it
Between angle when being within 30 ° (at i.e. 0~30 °), the first magnetic absorption member can be by second magnetic absorption member, so that scraper plate turns to
It arranges in poor plane.In addition, with reference to Fig. 2 b, in the present embodiment, when scraper plate 12 is located at row grain plane P3,131 edge of the first magnetic absorption member
