JPS584524B2 - Two-row stem culm lifting device - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is attached to the front end of a combine harvester, etc., and pulls two adjacent stem culms toward one stem culm side using one pulling device into one pulling path. This invention relates to a two-row stem culm lifting and reaping device that harvests the stem culms after the stem culms are raised along the rear and upward sides.

This two-row stem culm pulling and reaping device is capable of pulling up two stem culms with the lifting device and pulling a group of stem culms to the outside of one of the stem culms, as shown in the figure. In order to increase the width, it can be done by simply adding a lifting chain, which has the advantage of being simple, compact, and inexpensive. It has the advantage that it can also be used as a stem culm merging device.

However, in the past, the two-row stem culm was pulled up all at once along one stem length side by two pulling devices, and the two-row stem culm was harvested in the state that it was pulled up all at once. This had a negative impact on the reaping work that follows the raising, such as causing uneven cutting heights.

In other words, since both stem culms are pulled toward one stem culm side and pulled up, one stem culm is in a vertical posture when viewed from the front, and the other stem culm is in an inclined posture leaning toward one stem culm side. When cutting in this position, the cutting heights of both stems and culms will naturally differ.

Moreover, if the stem culm is short, it will be pulled toward one stem culm ray side and tilted, making the engagement between the lifting device and the short inclined stem culm unstable, which may easily lead to mistakes in lifting. It was.

In view of this point, the present invention aims to raise the two-lined stem culm in a state where reaping can be performed accurately, reliably, and smoothly, that is, with good efficiency.

An example will be explained below based on the drawings.

A pulling chain 4 having a plurality of pulling pawls 3 is conveyed through three sprocket holes 5 into an inclined plane with the front end located below near the ground. One pulling device 1, which is formed by rotatably hanging the part 1a in an L-shape, and pulls two adjacent stem culms toward one stem culm side and pulls them all at once backward and upward. and a reaping device 1 that reaps the stalks pulled up by these pulling devices 1.
A and a vertical/horizontal feed device 1B using an endless rotary body that conveys the stem culms cut by this reaping device IA in the lateral and inward direction of the machine body, and subsequently conveys them to the rear of the machine body. It is installed.

And between the pulling device 11 and the reaping device IA,
Its starting end is on the lateral side of the upward and rearward lifting action path 1a of the conveyance action section 1a, and the lifting action path 1
A lifting action route 1 which is located in front of the a1 end, and whose terminal end is in the center of the two stem culms.A tilted conveyance action route which is located behind the a1 end and whose front end is located below the ground. A rotary chain 7 with a stem culm engaging and conveying protrusion 6a in a posture inclined to the ground and a guide 8 are provided to form the stem culm 2A, and the two stem culms pulled up by the lifting device 1 are provided with a rotary chain 7 and a guide 8. A return transfer device 2 is provided for returning the intermediate portion of the stock to the central position between the stocks.

In the figure, 1' is another pulling device placed on one side of the pulling device 1, and IB' is a stem that has been pulled up by the other pulling device 1 and then cut by the reaping device 1A. 1C vertical and horizontal feeding device that uses an endless rotating body to transport the culm to the center of the machine and then to the rear of the machine
9 is an auxiliary conveyance device for the stem culm that is pulled up by the separate pulling device 1', and 9... is the three parts that are commonly arranged on both the left and right sides of the both lifting devices 1 and 1'. It is a grass rod.

Therefore, the two stem culms are pulled towards one stem culm side by the pulling device 1 and pulled up backwards and upwards all at once, and then the two stem culms are moved upwardly in the center between the stems by the return transfer device 2. The intermediate stem portion is merged and harvested by the reaping device 1A,
Then, it is transported to one side of the machine body by the vertical and horizontal transport device 1B.

As described above, according to the present invention, between a pulling device and a reaping device, at least the intermediate stem portion of the two stem culms raised by the pulling device is placed at the center between the rows of the adjacent stem culms. Since a return transfer device is provided for returning the stem culm to the position or approximately the center position, the two stem culms can be pulled to one side of the stem culm and pulled up with their postures being different from each other. The stem culms can be harvested in a symmetrical merging state, and therefore, it has become possible to cut the two stem culms accurately and reliably by making the cutting height of the two stem culms equal.
