Description

[Detailed description of the invention] The present invention is based on a direct current type combine harvester, specifically, a handling chamber in which harvested grain culm is introduced from the reaping section through a carry-in route, and is fed from the front central entrance of the handling drum to the lower part of the handling drum. Grain culms, which are transferred from the bottom to the top as the handling barrel rotates, are separated and diffused from the center of the rear part of the handling chamber to both sides of the front part of the handling chamber. A dispersion guide plate is provided for re-supplying from below, and a beater is installed at the rear left and right of the handling drum for discharging the threshed material discharged from the left and right discharge ports at the lower rear of the handling drum onto the rear sorting path. This article relates to a DC type combine harvester installed in

In conventional DC combine harvesters of this kind, the grain culm brought in from the cutting section at the front of the machine is threshed in a handling room, and the waste straw and grains mixed in this waste straw are processed after the threshing process. Alternatively, so-called second materials that need to be reprocessed are supplied to a sorting device installed at the rear of the handling room, and the waste straw after being sorted by the swinging motion of this sorting device is discharged to the rear of the machine. It was hot.

However, in the case of the conventional structure described above, the threshed material discharged from the handling room is discharged to the left and right sides of the sorting path, so the central part of the sorting path does not contribute to the sorting action, and the sorting path It had the disadvantage that it could not be used effectively as a whole.

The present invention has been developed in view of the above-mentioned conventional circumstances, and its purpose is to adjust the spread of the processed materials discharged onto the sorting route in the discharge direction, thereby allowing the processing materials to be sorted throughout the sorting route. The purpose of the present invention is to provide a DC type combine harvester that can effectively perform the following operations.

In order to achieve the above object, the DC type combine harvester according to the present invention is provided with beater curtains behind both of the beaters, respectively, in a state in which a part of the processed material is flow-guided to the center of the sorting path. It has the following characteristics.

Due to the above characteristic structure, the following excellent effects have been achieved.

That is, since the material to be processed discharged from the left and right beaters is configured to be flow-guided by the beater curtain provided behind the beater curtains so as to spread toward the center of the sorting path, the material to be processed is sorted. The material is now evenly distributed and supplied in the width direction of the path, so that the sorting action can be carried out effectively over the entire sorting path.

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in FIGS. 1 and 2, a reaping section 2 is provided at the front of the machine body 1, a conveyor 4 serves as a carry-in route for transferring the grain culms cut by the reaping section 2 to a handling chamber 3, and a conveyor 4 is provided in the handling chamber 3. The processed grain culm is transferred to the machine 1.
Left and right beaters 6, 6' discharging to a sorting section 5 as a sorting path provided at the rear, and traveling crawler devices 7, 7 provided at the bottom of the machine body 1 constitute a DC type combine harvester.

The reaping section 2 is equipped with a weeding tool 8, a pulling reel 9, a cutting blade 10, and an auger 11 that collects the cut grain culms in the center. After continuously harvesting the grain culms introduced from the grains and collecting them in the front central part of the handling chamber 3,
The grain stems are sequentially transferred to the handling room 3 via the conveyor 4.

When configuring the handling chamber 3, there is a handling cylinder 12 inside the handling chamber 3.
A cone cave 13 for separating threshed grains and grain culms is disposed on the lower surface of the handling drum 12, and a dispersion guide plate 14 is provided on the inside upper surface along the upper surface of the handling drum 12. , 14 are provided.

Then, as the handling drum 12 rotates, the grain culms introduced and supplied from the front central entrance 3a of the handling chamber 3 to the lower center of the handling drum 12 via the conveyor 4 are transferred from the lower part to the upper part thereof. The grain culm is dispersed and diffused from the center of the rear part to both sides of the front part by the distribution guide plates 14, 14, and is re-supplied from below both sides of the front part of the handling cylinder 12, and is threshed by the entire handling cylinder 12, and the threshing process is performed. The materials are discharged into the sorting section 5 through the beaters 6, 6' from discharge ports 3b, 3b' provided on both left and right sides of the rear of the handling chamber.

By the way, the discharge ports 3b, 3b' have a width L of the central entrance 3a of the handling chamber 3, a width L of both ends thereof,
1, and the threshing material from the left and right sides of the handling barrel 12 as well as the threshing material from the central portion are directly discharged without being transferred upwards as described above. It is structured as follows.

Furthermore, the beaters 6 and 6' are arranged over the entire width of the discharge ports 3b and 3b', respectively, so that the processed material discharged directly rearward from the handling chamber is also transferred onto the rear sorting section 5. It is configured so as to act to emit.

The sorting section 5 includes the handling chamber discharge ports 3b, 3.
A straw walker 15 extending from below b' to the rear of the fuselage 1, and a chaff sheave 1 disposed below it.
6, a grain sieve 17, a grain sieve 18 that generates a sorting air, etc., and a first screw conveyor 20 for transporting the sorted grains to a grain tank 19, and a second conveyor for handling the second grains that need to be reprocessed. A second screw conveyor 21 is provided for refeeding the chamber 3.

As shown in FIG. 3, to the rear of the beaters 6, 6', the threshed material is also supplied to the center, which is discharged onto the straw walker 15 via the beaters 6, 6'. the lower edge 2
Beater curtains 22, 22' are provided such that the beater curtains 2a, 22a' are inclined upward toward the center of the straw walker 15. Therefore, the processed materials discharged from the left and right discharge ports 3b, 3b' of the handling chamber 3 are distributed and supplied over the entire width of the sorting section 5.

Next, another embodiment of the present invention will be described based on FIG. 4.

That is, in order to guide the flow of the processed material to the central part of the sorting section 5 of the beater curtains 22, 22', the straw walker 15 is tilted backward toward the central part of the straw walker 15; The beater curtains 22, 22' are arranged so as to form an inverted V-shape when viewed. Therefore, in this case as well, the processed materials discharged from the left and right discharge ports 3b, 3b' of the handling chamber 3 are distributed and supplied over the entire width of the sorting section 5, as in the embodiment described above.

The structure of the beater curtains 22, 22' is as follows:
It may be a combination of the structure shown in FIG. 3 in which the lower edges 22a, 22a' are inclined, and the structure shown in FIG. 4 in which the lower edges 22a, 22a' are inclined toward the rear and toward the center.
