Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention aims to improve the sorting performance of a threshing device mounted on a combine harvester.

(b) Prior Art] A technique such as Japanese Utility Model Publication No. 53-23668 was found as a technique in which an orthogonal processing cylinder for firing directly with the processing cylinder was arranged behind the processing cylinder of the unbain.

However, the orthogonal processing cylinders in these conventional techniques simply place the parallel processing cylinder, which was conventionally arranged parallel to the processing cylinder, at the rear end of the processing cylinder, and in terms of sorting performance, they are not as good as the conventional parallel processing cylinders. There was no big difference.

(c) Problems to be solved by the invention In contrast, the orthogonal processing cylinder of the present invention, as in the past, simply reduces the No. 2 processing trunk that has fallen onto the two-way conveyor and transfers it onto the oscillating sorting device. Instead of returning the waste, the material that was discharged from the stroke rack at the end of the oscillating sorting device and discharged outside the machine from the three ports is to be processed again in the orthogonal processing cylinder and then discharged outside the wall. It is.

However, a suction fan must also be installed in this orthogonal processing cylinder, and depending on the arrangement of the orthogonal processing cylinder and the suction fan, grains with straw, etc. being processed in the orthogonal processing cylinder may fly into the suction fan and exit the machine. There are problems such as the water being discharged into the water.

In the present invention, in order to prevent such problems from occurring, the orthogonal processing cylinder is arranged between the second flow grain plates of the two-way conveyor, and the lower plate of the suction duct and the lower plate of the suction duct are arranged on the upper extension of the side plate of the orthogonal processing chamber. It consists of connecting shielding plates.

B) Means for solving the problem In order to achieve the above object, the present invention is constructed as follows.

An orthogonal processing cylinder that is orthogonal to the processing cylinder (1) is provided at the lower end of the swing sorting device, a suction device is provided above the rear part of the orthogonal processing cylinder, and the opening of the suction duct is directed toward the processing cylinder,
The orthogonal processing chamber side plate (toward) is constructed continuously, and its extension is a shielding plate 1211 connected to the lower plate of the suction duct.

(E) Embodiments and Functions The purpose and structure of the present invention are as described above.The structure and functions of the embodiments will now be explained based on the attached drawings.

FIG. 1 is a perspective view of the sorting device of the present invention. Figure 2 is also the side I#? Surface diagram. FIG. 3 is an enlarged side view of the palace near the orthogonal processing cylinder. FIG. 4 is a rear sectional view as well. FIG. 5 is a plan view of the vicinity of the orthogonal processing cylinder. FIG. 6 is also a rear view.

First, let me explain the overall structure.

The grain culm is raised by the puller of the combine harvester and transported by the reaping and transporting device. Pass through the handling room (c). At that time, the ears are treated as one trunk (1
), the fine grains are removed by contact with the handling teeth (1a) of the machine, and the fine grains fall from the crimp net (5) onto the sorting plate (7a) of the oscillating sorting device (7).

In addition, confectionery grains, chaff, etc. fall slowly from the crimp net and are placed on the straw rack (7b). Granules falling from the straw rack (7b) and sorting board (7a)
The fine grains sent from the
C), from the 1st stream grain plate (to) to the 1st stream conveyor (
Enter 8). The first inspection conveyor (8) is connected to the grain frying conveyor 9, and fine grains are sent to the grain tank.

In addition, the waste straw and the chaff and grains attached to it are transferred to the straw removal conveyor from the 4th port, and the straw waste and chaff that fell at the 411th port are transferred to the straw rack of the swing sorting device t (7). 7b
) or I@i+mtlα. Conventionally, the straw waste and chaff sent from the oscillating sorting device (7) to the sieve #2
Except for those that fell onto the #r conveyor (9), they were discharged as they were from the 3-way outlet, but the present invention has developed a processing cylinder that is orthogonal to the top of the 4-way conveyor and above the 2'4F conveyor. (3) is provided to handle the straw waste and chaff coming out of the three-sink opening and reprocess it with the tooth (3a). When the grains are separated from straw waste, chaff, etc. by this treatment, they fall through the concave (c) of the orthogonal processing drum (3) and enter the two-way conveyor (9). The 211 conveyor (9) was about to fall onto the No. 1 conveyor (8), but was blown away by the wind of the sorting fan (6), and fell from the end of the 1st stream grain plate (toward) to the 2nd stream grain plate (2). The incoming No. 2 grains and the No. 2 grains that have passed through the surface line and fallen onto the No. 2 grain plate (5) are collected and gathered to the right side of the threshing section, and then moved to the No. 2 thrower U. (To) The second thrower cylinder I returns to the parallel processing cylinder (2) which is parallel to the processing cylinder (1). The grains processed by the handling teeth (2a) of the parallel processing cylinder (2) fall from the concape onto the swinging sorting device 11 (7) again, and the straw and culms that do not pass through the concape go to the handling room (toward). return.

In addition, a suction duct (t18) is disposed above the orthogonal processing cylinder (3) over the entire width of the threshing section.
1, all the dust generated within the threshing machine frame is suctioned and blown out to the dust exhaust port Uη by a suction fan (4) provided on the side.

In such an overall configuration, the present invention includes a side plate (2), a shielding plate (2), and a second grain plate (towards) of the orthogonal processing cylinder (3).
, regarding the position and shape of the processing chamber rotating plate 4.

As shown in Fig. 3, Fig. 4, Fig. 5, and Fig. g6, the orthogonal processing cylinder (3) is equipped with handling teeth (3a), above which the processed material is sent through a sieve M, etc. It is brought in and put in. Send the processing material to the delivery/closing plate clD and the processing chamber rotation plate 4 by sending the feed plate ua”a to the 3′:fM port so that these are efficiently bitten and flowed toward the 3rd port. It is arranged at an angle.

Further, a concave is arranged at the bottom of the orthogonal processing cylinder (3), from which the chaffed grains enter the two-way conveyor.

Further, a third port for discharging straw waste and chaff after processing is provided at the left end 9 of the orthogonal processing cylinder (3) toward the outside of the machine. The processing chamber of the orthogonal processing cylinder (3) is surrounded by a dogleg-shaped processing chamber surrounding wall at the front part, and extended from this by a concave slurry at the lower part, and a side plate (C) and two bud flow grain plates (C) at the rear part. After) 1. (51
, and the upper part thereof is covered with a shielding plate 31) leading to the suction duct u8I. The shielding plate 31) is tilted forward in an overhang shape, and the orthogonal processing cylinder (31) is
) The material being processed is splashed up into the suction duct
It is configured so that it will not be sucked into gJ.

In addition, the processing chamber rotating board is configured in a dogleg shape or an arc shape similar to this, with the upper part slanted backward approximately on the extension of the first grain board (toward), and the lower part is curved around the outer periphery of the orthogonal processing cylinder (3), and looks over the two-way conveyor (9) or onto the concave (c).

(F) Effects of the Invention Since the present invention has the above configuration, it simulates the following effects.

The No. 2 processed material fed into the processing cylinder from the oscillating sorting device is dispersed and then either falls through the leakage section or is ejected out of the machine through the exhaust port by horizontal feeding. Some of the debris also flew upwards from the orthogonal processing chamber, and this debris was sucked into the suction duct. By configuring the shielding plate as in the present invention, grains that collide with the shielding plate and move while being lodged can be returned to the orthogonal processing chamber and then to the two-way conveyor via the orthogonal processing chamber. It is possible to reduce grain loss.
