Description

[Detailed description of the invention] [Industrial application field] The present invention has a harvested grain culm in the center of the front plate of a handling chamber that is equipped with a handling barrel that rotates around a horizontal axis and a concave located below the handling barrel. In addition to connecting a feeding feeder, a discharge port is provided on both sides of the rear plate, and the processed material supplied from the feeder is rotated once from the bottom of the handling cylinder in the direction of rotation, and then discharged from both sides. The present invention relates to a whole-culm input type combine harvester configured to disperse and guide the culm to the exit.

[Conventional technology]

In the case of such a full culm input type combine harvester, for example, as shown in Japanese Utility Model Application Publication No. 131135/1983,
After handling and processing the harvested grain culm input from the feeder in the lower side of the handling drum and in the center area of the concave, it is rotated once along the rotational direction of the handling drum and distributed to the left and right, and then handled on the second rotation. The paddy is handled again on the lower side of the shell and on both sides of the concave, and the paddy is filtered and the remaining residue is distributed and guided to the outlet in the rear side plate.

[Problem that the invention attempts to solve]

However, in the case of a full-culm loading type combine harvester with the above-mentioned structure, even if the harvested grain culm is rotated one and a half revolutions in the handling chamber and then distributed and guided to the discharge port, the handling action of the harvested grain culm is only applied to the handling barrel and concave. In fact, it only takes place twice, immediately after being fed from the feeder and immediately before being guided to the discharge port, which is also short in terms of time. And in other places, the treatment effect does not reach,
The reality was that the harvesting culm merely rotated with the handling barrel.

Therefore, the present invention focuses on this situation and aims to promote threshing by making the handling action on the harvested grain culm supplied in the handling room more effective, thereby improving threshing performance. The purpose is

[Means for solving problems]

A characteristic feature of the present invention, which has been made to achieve the above object, is that a resistance member is provided on the side of the front plate to protrude into the passage of the material to be processed, and its effects are as follows.

[Effect]

In other words, the grains introduced into the handling chamber from the feeder are handled at the bottom of the handling barrel and in the center area of the concave, and then rotated once as the handling barrel rotates while being distributed to the left and right. At a position near the front plate, the resistance member and the handling cylinder receive handling action, and the
During each round, the handling action is applied to the lower side of the handling barrel and on both sides of the concave, and finally, the unfiltered residue is dispersed and guided to both discharge ports.

[Effect of idea]

Therefore, by providing the resistance member, there are more opportunities for the harvested grain culm to be subjected to handling action in the handling room,
This promoted threshing and improved threshing performance.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings. As shown in Fig. 3, it consists of a reel 1 that raises the planted grain culms and scrapes them toward the rear of the machine, a reaping device 2 that reaps the raked grain culms, and a conveyor 3 that transports the harvested grain culms to the rear of the machine. A feeder 4 is equipped with a reaping pre-processing device A in the front part and is provided in the center of the front side to receive the reaped grain culms to be transferred by the conveyor 3.
A threshing section B which inputs paddy into the handling chamber 5 and applies a handling action by a handling cylinder 6 and a concave 7, and a sorting device C which sorts the processed material filtered and supplied from the handling chamber 5 and recovers the paddy. This is a full culm input type combine harvester.

Next, the threshing section B will be explained.

As shown in FIGS. 1 and 2, the feeder 4 is located in the center of the front plate 5a of the handling chamber 5, and the discharge port 9 equipped with a beater 16 is provided on both left and right sides of the rear plate 5b.
a, 9b are provided, and the handling barrel 6, which is pivoted in the handling chamber 5, has handling teeth 6a, the concave 7 has receiving teeth 8a, and furthermore, the front plate 5a has chevron-shaped resistors on both sides. A member 10 is provided respectively. Furthermore, a second return port 11 is provided at the upper part of the feeder 4 for returning second products such as paddy with branches collected from the sorting device C into the handling chamber 5.

With the above configuration, the harvested grain culm fed into the handling chamber 5 from the feeder 4 is planted in the central area on the lower side of the handling barrel 6 together with the second crop fed from the second return port 11. After receiving the handling action by the handling teeth 6a and the receiving teeth 8a, they are distributed to the left and right by the upper guide plate 12 while rotating as the handling cylinder 6 rotates, and then reach the front side plate 5a. The resistance member 10
and is subjected to handling action by the handling teeth 6a. Further, in the second rotation, the handling teeth 6a and receiving teeth 8a are implanted on both sides.
The residues such as straw waste that are not finally filtered are removed through the discharge ports 9a and 9b.
The water is dispersed and guided and discharged to the straw walker 13 at the rear. The processed material is filtered and supplied onto the clean pan 14 after being handled, and then subjected to specific gravity separation by the clean pan 14.
The residue discharged into the straw walker 13 is transferred to the straw walker 13, and the remaining paddy inside is transferred to the lower sorting device C.
While being filtered and supplied to the machine, it is oscillatedly transferred to the rear discharge port 15 and discharged outside the machine.

[Another example]

As shown in FIG. 4, the resistance member 10 may be configured to have a receiving tooth shape. Moreover, the resistance member 10
may be provided not only on the side portion of the front side plate 5a but also in a series from the left end to the right end.Furthermore, in the embodiment, the resistance member 10 and the handling tooth 6a are in a lapped state in a side view, but the It may be carried out without the
