Description

[Detailed description of the invention] The present invention provides a pair of left and right stem culm scraping puckers that drive and rotate in an occlusal state to scrape the stem culm backwards, and a rotation support shaft for one of the two puckers. This invention relates to a structure of a culm scraping part in a reaper, in which a reciprocating swinging arm for driving a clipper-type reaping device for cutting the base of a culm is externally fitted and supported on a lower part of the culm.

The above-mentioned stem culm rake-in structure is designed to reduce the cost of the overall structure by using the rotary shaft of the packer as the shaft of the reciprocating swing arm for driving the reaping device. I had the following problem.

That is, stalk culm guides are provided at the upper and lower parts of each of the two packers to guide the stalk along a desired path while preventing the stem culm from coming close to the rotational axis of each of the two packers. However, in the past, the stalk culm guide was constructed using a bar, and although the stalk culm guiding function could be fully exerted, the straw debris detached from the stalk culm could not reach the reciprocating swing arm for driving the reaping device. There was a problem that a large amount of adhesive remained and had a negative effect on the operation of the arm.

The present invention has been made with the above-mentioned circumstances in mind, and in the stem culm rake section structure of the above-mentioned reaping machine, the swing arm is installed at the lower part of the culm car. A stem culm guide plate is erected in the form of a vertical wall to cover the lateral side of the inside of the fuselage from the front part of the swinging arm in a series. It is characterized by the fact that a stem culm guide with a small vertical width is provided at the upper and lower parts of the packer.

That is, a stem culm guide device that can be constructed easily and inexpensively from a bar or a punched plate is provided at the upper part of one arm which is equipped with a swinging arm, and at the upper and lower parts of the other arm. Since the stem culm guide plate is installed upright at the bottom of the stick car where the arm is installed and also serves as a cover for the swinging arm, the structure as a whole is relatively inexpensive and simple, and the stem culm guiding function is achieved. and the cover action of the swing arm, making it possible to use it satisfactorily for a long period of time. More specifically, the stem culm guide plate is erected only in the part where it is necessary to cover the swinging arm, and the other part is provided with a stem culm guide that can be constructed easily and at low cost. In the part where the movable arm is installed, compared to configuring the stem culm guide and the cover body separately, it is a cheaper and simpler structure in which only one stem culm guide plate is provided, and it is practical. This is a huge advantage.

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

Figure 1 shows a side view of the entire combine harvester as an example of a reaping machine.The front part of the combine harvester, which is equipped with a crawler traveling device 1, a threshing device 2, etc. A pair of left and right pulling devices 8a and 3b that pull up the stem into an upright position, a clipper-type reaping device 4 that cuts the base of the stem culm after pulling it up, and a pair of left and right stems that are driven and rotated in the occlusal state to scrape the stem culm backwards. A reaping processing unit including culm raking packers 5a, 5b, a rear conveyance device 7 for conveying the culm culms that have been raked and merged rearward and delivers them to the threshing feed chain 6 is connected and equipped.

Next, the structure of the stem culm rake part to which the left and right packers 5a, 5b are attached will be described in detail.

A reciprocating swinging arm 9 for driving the clipper-type reaping device 4 for cutting the base of the stem culm is externally fitted and pivoted on the lower part of the rotation support shaft 8 of the right-hand pruner 5b of the two pruners 5a and 5b. The arm 9 is configured to lock the movable blade 4a of the reaping device 4 and move it reciprocatingly and laterally along the fixed blade 4b with a constant stroke. The swing arm 9 is pivotally connected to a rod 10 which is reciprocated back and forth by a crank mechanism of the machine, and is driven to swing back and forth. The rotation support shaft 8 of the right side car 5b is connected to the lifting device 3a, 3b.
The outputs from the two are branched and interlocked to drive and rotate, thereby driving and rotating the supported pack car 5b. The left packer 5a is driven and rotated by engagement with the right packer 5b, and its rotational support shaft 11 is rotatably supported.

A drum-shaped wrapping prevention device 12 is fixed to the upper part of the swinging arm 9 and swings back and forth together with the arm 9 to prevent straw waste from being wrapped around the rotating shaft 11. At the bottom of the right patrol car 5b equipped with the arm 9, a culm guide plate 13 is erected in the form of a vertical wall, covering the front part of the swinging arm 9 and the lateral part of the inside of the body in series. ing. This stem culm guide plate 13 has a rib 13a along the stem culm movement direction.
is provided in a protruding manner to reinforce the guide plate 12 itself and to reduce the sliding resistance of the stem culm. Further, on the upper part of the right side pack car 5b, a stem culm guide 14 made of a bar is provided in a backward cantilevered manner extending from the front of the car to the side of the inside of the car. The intermediate portion of the rotary support shaft 11 is connected to a shaft cover 15 disposed around the rotational support shaft 11 by a connecting plate 16, thereby preventing rotation of the shaft cover 15 and reinforcing the cantilevered guide member 14.

In addition, a stem culm guide 17 made of a bar extending from the front of the pack car to the side and rear of the inside of the body is provided on the upper part of the left pack car 5a.
A stem culm guide 18 made of flat plate material is provided vertically on the rear side of the lower part of the packer, and this downward guide 1
At step 8, the culm is raked and transported to the lower part of the packer, and weeds are prevented from entering from below.
