Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine sorter in which grains such as rice and wheat, which have been threshed by a handling cylinder, are rocked and sorted by a rocking sorter below the same. It relates to a sorting device. 2. Description of the Related Art During the rocking operation of a rocking sorter, the straw that has moved to the rear end of the sorter is subjected to sieve sorting by a sieve line, falls from the sieve line, and is mixed with straw waste and straw waste. Kernels are removed from the debris. [0003] However, in the case of a structure in which some of the waste such as straw from the sieving line falls first on the drifting board, sorting is performed in which the first waste is mixed with straw. There is a disadvantage that the accuracy is reduced. SUMMARY OF THE INVENTION Accordingly, the present invention relates to a method for connecting a front end of an upper sieve line to a rear end of an oscillating screen, and connecting a rear end of the screen to an upper rear side of the oscillating screen. together to extend to, before

Further, the upper sieving line (28) has a horizontal horizontal line (28a) with a horizontal cross section and a vertical line (28b) with a circular cross section in the front-rear direction at substantially constant intervals in the horizontal direction. As shown in FIG. 7, the lower sieving line (29) is formed by notching the rear side of a single spring steel flat plate (29a) at substantially equal left and right intervals, as shown in FIG. Are integrally formed, and an upper sieving wire (28) is placed on a sieving wire receiver (53) extending between the upper surfaces of the bent end portions (45a) of the left and right swing arms (45). Bend (45
A lower sieving line (29) is fixed between the lower surfaces of (a), and a holding plate (54) for holding the horizontal line (28a) of the upper sieving line (28) is provided on the upper surface of the sieving line receiver (53). ,
The flat portion (29a) of the lower sieving line (29), the sieving line receiver (53) and the holding plate (5) are provided on the bent portion (45a).
The upper and lower sieving lines (28) and (29) are attached by fixing the 4) integrally via bolts (55). Further, when the upper and lower sieve lines (28) and (29) are attached, as shown in FIG. 5, the lower lower sieve is located substantially at the center between the vertical lines (28b) of the upper sieve line (28). The comb teeth (29b) of the line (29) are positioned, and the rear end of the vertical line (28b) of the upper sieving line (28) is bent upward to extend to near the rear side of the suction port (35). The rear end of the comb teeth (29b) of the lower sieving line (29) extends rearward from the rear end of the extension plate (50), and the upper sieving line (2)
8) The swarf falling from the sifter is further sieved and selected by the lower sieving line (29), and only the grains mixed in the swarf and small swarf are dropped toward the first conveyor (31) to improve the sorting performance. It is configured to be. Since the sieve lines (28) and (29) swing up and down around the roller shaft (42) simultaneously with the movement of the sorting machine (22), the fins at the rearmost end of the chaff sheave (26) are formed. (38), it is necessary to provide a space (A) for securing the movement allowance, and the fixing fin (3)
9) is provided in this space portion (A) so that the grains flow down to the front lower side without interfering with the sieving lines (28) and (29), and the leakage area of the sorter (22) is effectively reduced. It is configured to increase. As shown in FIGS. 8 to 10, the blown air is discharged into the air blowout port (57) of the fan casing (56) of the suction and discharge dust fan (34).
7) A dust exhaust direction plate (58) having a cross section in a rear view, which is guided downward to the right, is provided. A wind direction plate (58) is provided so as to cover the rear left side of the air outlet (57). The inner surface (58a) of (58) is curved from the front end to the rear end toward the inside of the machine body. A straw upper shooter (59) for guiding the straw from the straw cutters (36) (37) into the wind direction plate (58) is provided at the lower left side of the straw processing section (9), and the wind direction plate (58) is provided. ), A cutout opening (60) for joining the lower end of the shooter (59) is formed on the upper surface (58b), and the rear side of the wind direction plate (58) and the upper shooter (5).
9) A lower chute (61) that covers the lower space from the left side and guides toward the inside of the fuselage is fixed to the rear end of the wind direction plate (58) via a bolt (62). ) And the cuts by the cutters (36) and (37) are collected and discharged near the right side of the machine. As shown in FIG. 11, the wind direction plate (5)
A guide shooter (63) integrating the upper and lower shooters (59) and (61) with 8) may be provided between the suction / discharge dust fan (34) and the left side of the straw processing section (9). This embodiment is constructed as described above. In addition to the oscillating upper sieving line (28) at the rear end of the oscillating sorter (22), the oscillating lower sieving line (29) ), And the comb teeth (29b) of the lower sieving line (29) that allows the straw chips falling from the upper sieving line (28) to reach between the vertical lines (28b) below the upper sieving line (28). The sieve is effectively sorted, and only small straw chips and grains falling from the front of the lower sieve line (29) are guided to the first conveyor (31) to improve the sorting performance. As is apparent from the above embodiments, the present invention relates to a swing sorter (22) in which the front end of the upper sieving line (28) is connected to the rear end thereof. causes extended to the side above after the rear end of the swing sorting machine (22), the upper sieve line (28) lower sieve line to face in the lateral spacing width (2
9) is provided on the lower side of the upper sieving line (28) of the oscillating sorter (22) in a combine sorting apparatus.
Upper sieve line formed by a number of vertical lines (28b) of shape
(28) is extended behind the dust suction port (35).
On the other hand, a spring flat plate is formed by a notched comb tooth (29b).
The lower sieving line (29) to the conveyor (31)
Extending behind the plate (50) through which the water flows down, and an elongated upper screen
The comb teeth (29b) are wider and shorter than the
And drop the selected grain to the conveyor (31) side.
What is further sieved Warakuzu falling from the top sieve line (28) in the lower sieve line (29), and Rukoto allowed <br/> grain is falling the most side, and a double-dip Warakuzu Dropping to the side can be promoted, and remarkable effects such as remarkable improvement of the sorting performance can be obtained.
