Abstract

PURPOSE:To prevent grains and culms from remaining at a gathering part by attaching guide members lower than the gathering nails at an angle with respect to the direction of rotation to the outer periphery of a rotary drum in gathering nail-attached regions. CONSTITUTION:Even when reaped grains and culms sent laterally by an auger 11 are parallel to the direction of rotation of gathering nails 16 at a gathering part 15, the grains and culms are introduced at an angle by guide members 17 so as to change the attitude. The grains and culms and the direction of rotation of the gathering nails 16 are crossed thereby and an effective gathering operation can be carried out by the gathering nails 16 therefor. In addition thereto, the guide members 17 can be brought close to the path of the outer end of the gathering nails 16 as near as possible.

Description

Detailed Description of the Invention [Industrial Field of Application] The present invention is directed to a rotary drum that collects the culms cut by a reaping device along the lateral direction by an auger, and is provided in a raking section in series with the auger. The present invention relates to a shell culm conveying section structure of a full culm input type combine harvester, which is configured to send the shell culm to a feed conveyor by a scraping claw protruding radially outward from the culm.

[Conventional technology]

In the above shell culm conveying section structure, conventionally, as shown in, for example, Japanese Utility Model Application Publication No. 61=125230, the scraping pawl rotates around an axis eccentric from the rotation axis of the rotating drum. It is constructed of a bar that is movable and protrudes through the rotating drum so that it can move in and out of the rotating drum, so that it protrudes largely at the front side of the rotating drum to provide sufficient raking action, and the amount of protrusion is reduced at the rear side. It was designed to prevent interference with the feed conveyor.

[Problem to be solved by the invention]

However, in the above-mentioned conventional structure, since the scraping claw is a bar and rotates around the horizontal axis, the cutting shell culm does not move along the front-rear direction of the fuselage in its scraping action portion, for example. If the shell is carried in a straight position, the scraping action by the scraping claws will not be sufficient and the shell culm will accumulate, and when the shell culm accumulates in a lump, it will be sent towards the feed conveyor all at once. There was a risk that grain performance would deteriorate.

In particular, in the case where the cutting width is relatively short and the raking action section by the raking claws is disposed at the lateral end of the auger, the disadvantages described in 2. above are particularly noticeable. Ta.

The present invention aims to solve the above-mentioned problems.

[Means to solve the problem]

The characteristic configuration of the present invention is that, in the shell culm conveying section structure of the full-culm throwing large combine harvester described at the beginning, a guide member shorter in profile than the scraping claws is rotated on the outer peripheral part of the scraping claw installation area of the rotating drum. The point is that it is erected in an attitude that is diagonal to the direction.

[For production]

Even if the reaped husk culm that has been transversely fed by the auger is in the same direction as the rotational direction of the rake claw in the rake section, it is guided along the diagonal direction by the guide member and changes its orientation. Since the direction is perpendicular to the direction of rotation of the scraping claw, the scraping action of the scraping claw is effectively received. Moreover, since the guide member is located at the front bottom of the claw,
The foot conveyor and the outer end locus of the scraping claw can be made as close as possible.

〔Effect of the invention〕

Therefore, according to the present invention, by rational structural improvement, it is possible to prevent the shell culm from staying in the scratching part without inhibiting the feeding action of the scraping claw to the feed conveyor, and the shell culm becomes a lump. This avoids the inconvenience of the grain being fed into the threshing section in a curly state, and the threshing performance can be stabilized.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

As shown in Fig. 9, a reaping pre-processing section (2) equipped with a rotary reel (1) etc. that can be driven freely supplies the entire reaped husk to a handling chamber (3) and a rotating handling cylinder. (4), a threshing section that threshes grains; a sorting section that sorts the threshed material using a driving vibration sorting device (5), a sorting wind supplied by a winnowing machine (6), etc.;
A full culm input type combine harvester is constructed by connecting the front part of a crawler-type traveling body equipped with a threshing grain tank (7) and the like so that it can be swung up and down by a hydraulic cylinder (8).

The reaping pre-processing section (2) supplies the shell culm to a reaping device (9) by the movement of the machine and the scraping action of the rotary reel (1), and processes the shell culm cut by the reaping device (9). The handling room (3) is controlled by the auger (11) and feed conveyor (12).
).

Specifically, as shown in FIGS. 1 and 2, the auger (11) has a transverse feed screw (14) attached to the outer periphery of a rotating drum (13), and as the auger (14) rotates, the auger (11) reaps the crops as it rotates. The structure is such that the shell culm is transported laterally to a scraping part (15) on the left lateral side, and in the scraping part (15), a rotating drum (■ A plurality of claws (1) protrude radially outward from 3).
6) is configured to send the shell culm to the feed conveyor (12); The scraping claw (16) is configured to rotate around an axis that is slightly eccentric to the front and downward side from the rotation axis of the rotating drum (13), and penetrates the rotating tram (13) so as to be able to move in and out. The structure is configured such that it protrudes outward from the rotary drum (13), and protrudes largely on the front side of the rotating drum (13) to effectively scrape the reaped husk, while retracting inward from the rotating drum (13) on the rear side. (to prevent interference with the feed conveyor (12) and feed conveyor (12).
12) The structure is such that the starting ends are brought as close together as possible to facilitate smooth conveyance.

Further, a guide member (1) having a height lower than the scraping claw (16) is provided on the outer circumference of the rotating drum (13) in the scraping claw installation area.
17) is erected in a direction oblique to the direction of rotation. Specifically, as shown in FIGS. 3 and 4, the guide member (17) is a plate body formed into a curved shape along the outer periphery of the rotary drum (13).
It is attached diagonally along the outer periphery of the machine and in a flat position. In other words, the transverse feed screw (12
), it can be erected and fixed in its flat shape without twisting and deforming it. Further, as shown in FIG. 8, this guide member (17) controls the rotation of each row of scraping claws (16) arranged in parallel in the axial direction at a constant pitch in the circumferential direction of the rotating drum (13). Multiple units are arranged on the upper side of the direction. In this way, even if the cut culm is in a straight posture along the longitudinal direction of the aircraft, the guiding member (17) guides the culm to fall laterally, and the scraping claw (16) The structure is such that an effective scraping action is achieved.

As described above, the guide member (17) is provided in a flat plate shape, and as a result, as shown in FIGS. It takes a posture of falling down toward the lower side in the direction of rotation, and performs a gentle guiding action at the starting end of the action on the culm.Sequentially, the farther it is located on the lower side, the more it falls down toward the upper side in the direction of rotation, and the guiding action becomes stronger. The structure is such that a smooth sideways tilting action can be performed. Moreover, since the guide member (17) is provided lower than the scraping claw (16), the scraping starting end of the feed conveyor (12) can be placed as close to the outer end trajectory of the scraping claw (16) as possible. Since they can be placed close to each other, they can be smoothly transferred to and from the feed conveyor (12).

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
