Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a thresher.

(Prior Art) A full-volume combine combine equipped with a screw type handling cylinder, in which a screw type transfer device is provided below the handling cylinder, is known from Japanese Utility Model Publication No. 61-191752.

(Problems to be solved by the invention) The above-mentioned screw type transfer device receives a leaked substance from the handling cylinder, and then sends it to the transverse spirals orthogonal to each other to drop the leaked substance from the receiving net to the rocking rack. It is like this. Moreover, the screw type transfer device is configured as a screw that feeds from the front and the rear toward the horizontal spiral. However, since not all the leaked substances in the handling cylinder are sent to the Glensieve of the rocking rack via the horizontal spiral, the grains cannot be efficiently selected.

Therefore, the technical problem of the present invention is to reduce the sorting load on the rocking sorting board and to provide a sorting device for a thresher capable of improving the performance.

(Means for Solving the Problems) In order to achieve the above-mentioned objects, the present invention provides the following threshing machine.

That is, a screw type sorting / transferring device is provided below the handling cylinder, and the device is divided into a front half and a rear half. The front half is placed on a grensieve facing the first gutter of the rocking sorting board and its end is It is a sorting device for a thresher that is located above the grensieve on the chaff sheave that faces the rear, and the latter half is configured as a transfer device that sends it to the front of the machine and its discharge port is exposed on the chaff sheave of the rocking sorter. is there.

(Function) According to the present invention, the one that has leaked from the receiving net in the first half of the screw type sorting and transferring device is subjected to the paddy sorting by the grain sieve of the rocking sorting board, and the one that has not leaked is the middle opening of the transferring device. From the rocking sorting board, it falls on the chaff sheaves for straw sorting, and what is leaked from the net or the catch at the rear of the handling room is sent to the front of the machine by the transfer device in the latter half of the transfer device. It falls on the chaff sheave of the rocking sorting board from the opening in the middle and undergoes straw selection, and paddy sorting and straw sorting are performed by the Glensieve and the chaff sheave of the rocking sorting board, respectively.

(Example) An example shown in the drawings will be described below.

Generally, in a full-throw combine combine equipped with an axial flow thresher, the grain culm scratched by the scraping reel and cut by the cutting blade is carried from the scraping auger to the handling room by the chain conveyor of the feeder house, Threshing is done with a screw-type drum or rotor.

The threshed ones fall from the concave to the rocking sorter,
Grain that has been sorted by the sorting wind by Karako falls into the first gutter, second grain falls into the second gutter, and the grain dropped into the first gutter is carried to the paddy tank via the lifting cylinder. Has become.

(1) is its rotor, and (2) is a handling chamber. A sorting screw is arranged in the longitudinal direction between the handling chamber (2) and the swing sorting board (3).

(4) is a central selection screw, and (5) and (6) are left and right selection screws.
(7) and (8) indicate partitions that separate the center from the left and right sides.

Among the sorting screws as described above, the handling chamber corresponding to the central sorting screw is the receiving net (9), while the handling chambers corresponding to the double-sided sorting screws are the receptacles (10) (11).

And, the sorting screws as described above extend up to the chaff sheave (3b) start end of the rocking sorting board (3), and the gutters (12), (13), (14) of the rocking sorting board (3). There are blind gutters (12a) (13a) (14a) up to the start end, and nets (12b) (13b) (14b) from the rocking sorter start end to the chaff sheave start end.

Gutter above the partition wall (21) between the first gutter (17) and the second gutter (20)
(12) (13) (14) is an opening (15) that straddles the first gutter (17) and the second gutter (20), and the rear gutters (12c) (13c) (1)
The screw (4a) (5a) (6a) which is a reverse screw to the screw (4) (5) (6) is provided in 4c).

In the figure, (18) is Kara Tan, (3a) is a Glensieve, (3c) is a Straw rack, and (3d) is a Yokochaff sheaf.

The sorting device configured as described above operates as follows.

That is, the one that leaked the handling room receiving net or the receiving box is the gutter (12)
(13) (14) blind gutter (12a) (13a) (14a) through the screw (4)
(5) It is transferred to the starting end of the rocking sorting board (3) by (6) and the net is received.
Those leaked at (12b), (13b) and (14b) are sorted on the Glensieve (3a) facing the first gutter, and paddy sorting is performed here.

Those that did not leak from the gutters (12b) (13b) (14b) were opened (1
From 5), it falls on the chaff sheave (3b) facing the rear above the Glen sieve and the straw is sorted.

Those that leaked from the receiving net or the catch at the rear of the handling room were the gutter (12c) (13
c) The screws (4a) (5a) (6a) of (14c) are transferred from the rear to the front and fall from the opening (15) onto the chaff sheave (3b) for sorting, and undergo straw selection.

As described above, the paddy sorting and the straw sorting can be performed by the Glensieves and the chaffsives of the rocking sorting board, so that the sorting can be improved.

By providing the screws (4a) (5a) (6a), the length of the sorting section can be shortened.

When the opening (15) is located above the second partition wall and straddles both gutters, the ones transferred from the front are the ones transferred from the front and those transferred from the back are mainly. It can be supplied above the second gutter, and the processing capacity of the rocking sorter can be improved.

Also, by making the lead angle of the handling barrel screw larger than the inclination angle of the screw handling barrel shaft, the processed material can be fed smoothly without causing the handling barrel to rotate at a high speed during mowing threshing, which may cause clogging in the handling chamber. Without it, the thresher can be compactly assembled.

(Effects of the Invention) According to the present invention, what has leaked from the receiving net of the first half of the screw type sorting and transferring device is not leaked because it is subjected to paddy sorting by the grain sieve facing the first gutter of the rocking sorting board. Was dropped from the midway opening of the transfer device above the Glensieve of the rocking sorter onto the chaff sheave facing the rear, and was straw-sorted, and was not leaked by the net or the catch behind the handling room. The objects are sent to the front of the machine by the transfer device in the latter half of the unit, fall through the opening in the middle of the transfer device onto the chaff sheaves of the rocking sorter, and undergo straw selection, so that paddy sorting and straw sorting are shaken. Since it is performed by the Glen Sieve or Chaff Sieve of the dynamic sorting board, the sorting load on the rocking sorting board can be lightened to improve the capacity, and the grains leaking from the latter half of the handling cylinder are mixed with the culm. Even from the culm It is not said that it is immediately discharged without being affected, and it is sent back to the front of the machine body for sorting, and a short sorting section can sufficiently receive the sorting action.
