Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a threshing and culm processing device, in which the culm that has been threshed by the threshing device is transferred to a tip passageway (3) where the middle part of the culm length is held between the culm removal device disposed at the rear. However, the soft tips of the stems are subject to resistance from straw debris that tends to accumulate, and delivery tends to be delayed.

At this time, the straw waste and grains that tend to accumulate are scraped off by providing a droplet to eliminate the transfer resistance of the discharge culm, thereby preventing disturbance of the discharge culm due to the delay of the tip and making the falling posture of the discharge culm orderly.

For this reason, the present invention has taken the following technical measures. That is, at a position corresponding to the tip side of the threshing device (2) which clamps and transfers the threshing method discarded culm on the rear side of the threshing device (1), the tip of the culm removed by this culm removal device (2) is received on the upper surface. The threshing and culm processing device has a structure in which a dropping hole (4) is provided in the middle of a tip path (3) that slides and guides the tips to drop straw debris swept up by the tips.

With this configuration, the present invention has the following technical effects. That is, the shell culm that has been threshed in the threshing device (1) is transferred to the culm removal device (2), and the tip of the culm is transferred by sliding it on the plate surface of the tip passage (3). Since the straw debris swept inside is constantly swept away through the droplet (4) provided in the middle of the tip path (3), normal conveyance can be achieved without any resistance during conveyance.

In the illustrated example, the side end of the threshing device (1) is provided with a clamping rod (5) and a clamping chain (6) for clamping and conveying the culm in the front and back direction, and a handling barrel (7) is installed in the center. A culm removal device (2) consisting of a culm removal cheno (8), a rod holder (11), etc. is suspended on the rear side of the threshing device (1).
) is disposed obliquely so that its front end is close to the pinching chain (6) and its rear end is deviated toward the tip of the culm and extends rearward. The lower end of the culm removal device (2) has a rectangular box with a part protruding from the body width of the threshing device (1) toward the tip side, and a cutting blade (13) and a receiving blade (
A cutting device (12) is provided in which the blade portions of the cutting device (14) and the cutting device (12) are mounted in parallel with each other so as to cross each other.

(15) is a dust removal device, which is equipped with a cross-flow fan (1
6) on the shaft and the upper shelf (17) and the lower part! ;The IJ plate (18) forms the dust removal cylinder, and (24) is the ear tip receiving plate.
It is located on the outside of the tip side of the shelf (17) and is flattened slightly below the upper surface of the shelf (17).
8), it is provided in a planar triangular shape and protrudes toward the tip side. The cutting device (12) is connected to these shelves (17).
) and the rear side of the ear receiving plate (24). The tip passageway (3) area includes the tip receiving plate (24) and the rear guide plate (
23) and the side part of the tip.

The guide plate (23) is divided into a tip side and a stock side across the culm exhaust chino (8), and is provided with a step above the joint surface of the dust removal device (15), The front end is bent downward so that the transfer culm can be brought into sliding contact with the transfer culm, and the rear end is also bent downward so that it can be easily slid off, and is rotatable on both sides to cover the blade in the cutting device (12). It is integrally pivotally connected to a pin (22).

The drop mark (4) is provided on the tip side of this guide plate (23) and opens on a canter. The culm Cheno (8) is handled by the handling cylinder (7)
A car box (9) pivotally attached to the shaft end and a universal joint (1)
o), and the cutting device 1it (12) and fan (1B) are driven by the threshing section. (19) is a threshing cover 1 (2o) is a culm cover, and (21) is a skirt.

The shell culm threshed by the threshing device (1) is transferred to the pinching chute (6).
From there, the culm is taken over by a culm evacuation device (2) installed close to this, and the culm is transported obliquely while being displaced. The culm shedding device (2)
is connected to the gear box (9) at the shaft end of the handling cylinder (7) via a universal joint (1o), etc., and the pinching chain (6)
The said culm ceno (8) is provided close to and rotates.
The lower rod (11) holds the discharged culm and moves it backward while shifting it toward the tip side. During this transfer, the grains and debris contained in the culms are removed by the dust removal device (15
) onto the rack (■7) and collected in the sorting section, and the straw waste and dust are combined with those generated by the threshing device (1) and discharged out of the machine by the fan (16). Ru.

The culm that is transferred while being held between the culm cenograph (8) and the culm receiver (11) is transported by the culm holder (11). (+e) Top tip receiving plate (24)
and the guide plate (23) attached to cover the blade of the cutting device (12), and the culm is transferred in a posture with the tip side being delayed, so that the dust removal device (15
) The straw waste and grains that could not fall during the process of passing over the fan (16) are pushed toward the tip side, and the joint or step between the tip receiving plate (23) on the fan (16) and the cutting device (12) is Even if the grains try to stagnate, the debris that is swept away by the tip of the ear is scraped off from the droplet (4) on the way, and does not provide a large transfer resistance to the tip of the ear.
