Description

[Detailed Description of the Invention] The present invention is configured to transfer the cut husk culm from a first clamping and conveying device to an underchain-type second clamping and conveying device of the threshing section, and the first and second The present invention relates to an agricultural combine harvester in which a holding tool is provided at the transfer point of the clamping and conveying device to clamp and guide the delivery shell culm from the first clamping and conveying device, thereby facilitating automatic delivery of the shell culm by both clamping and conveying devices.

Conventionally, in the above-mentioned combine harvester, in order to facilitate the direct supply of hand-cut husk culms to the threshing clamp conveyance device, the presser was placed above the clamping surface of the threshing clamp conveyance device configured in an underchain type. As if to shake the evacuation,
Alternatively, it was configured to move toward the outside of the aircraft.

However, when retracting and swinging upward, it is not possible to secure a sufficient amount of retracting and swinging due to the inherent structural limitations of the combine, and when retracting to the outside of the machine, the presser foot at Since the tool becomes an obstacle for the worker to hold the cut husk by hand, there is a problem in that no matter which of the above-mentioned configurations is employed, it is still not possible to sufficiently facilitate the supply of the cut culm by hand.

The purpose of the present invention is to make it possible to feed hand-cut culms extremely easily by simply changing the position of the presser by a small amount, through a rational and simple improvement to the presser. be.

The characteristic structure of the present invention is that, in the above-mentioned agricultural combine harvester, a clamping position overlaps the clamping surface of the second clamping and conveying device for threshing in plan view, and a non-operating position deviates from the clamping surface toward the handling barrel. Another feature is that the presser is configured to be able to change its position, and its functions and effects are as follows.

By changing the retracted position of the husk and presser to the handling barrel side, the amount of position change can be kept to a small amount within various structural constraints, and the hand-cut husk culm can be transferred to the husk holding and conveying device. When placing the culm on the clamping surface, it is possible to sufficiently avoid the use of the presser as a force for placing the culm on. Rather, the presser is effective as a stopper for the tip side of the hand-cut culm placed on the clamping surface. In addition, since the position is changed to the inside of the machine, the evacuated presser does not interfere with the worker's ability to hold the cut culm by hand, and as a result, it is an extremely simple improvement. However, it has now become possible to greatly facilitate the supply of hand-cut husk culms.

Next, embodiments of the present invention will be described in detail with reference to illustrative drawings.

A reaping device 2 is installed near the ground at the back of the lifting device 1 for the planted culm, and a culm scraping packer 3,
A plurality of pairs of 3 are provided in the direction of the culm, and a conveying device 4 is provided that conveys the collected culm backwards and collapses inside the machine near the end of the conveyance, and the culm from this conveying device 4 is held between the legs. The agricultural combine harvester is equipped with a threshing section 6 which is transferred by a conveying device 5 and threshed during the clamping and conveying process, and is also provided with a processing device 7 for removing straw after threshing. It is composed of a stock head clamping and conveying device 8 and a tip locking and conveying device 9. Of these, the stock head clamping and conveying device 8 is arranged so that its conveying end is located at the culm with respect to the pinching and conveying device 5 around the vertical axis P near its conveying start end. It is configured so that its position can be changed in the direction of the body, and the handling depth can be adjusted at the shell culm delivery location of both clamping and conveying devices 5 and 8.

At the delivery location, a presser 1 is provided for clamping and guiding the culms from the plant clamping and conveying device 8 to the clamping and conveying device 5.
0 is set.

This holding tool 10 has the above-mentioned clamping and conveying device 5 in a plan view.
The tip guide 11 is integrally connected to the tip guide 11 of the tip retaining and conveying device 9 in a state overlapping the clamping surface of the device 5, and the tip guide 11 has an axis P1 that is approximately orthogonal to the clamping surface of the clamping and conveying device 5. A position A where the holding tool 10 is supported by the lifting transmission cylinder 12 and overlaps the clamping surface in plan view at the axis P, -E, and a position away from the clamping surface toward the threshing section handling cylinder side. The fixing structure 1 is configured such that the position can be changed over a range between B and B, and the attachment provided on the transmission shaft 12 is made by a long hole provided between the plate 15 and the guide 11 and a fastener.
3, the two switching positions are fixed.

According to the above configuration, by changing the attitude of the presser 10 to the position B where it is removed from the clamping surface toward the handling cylinder side, with this slight position change, the clamping and conveying device 5 can be moved as shown in FIG. The shell culm transfer locking part 14.14 is exposed in a state where the locking is not obstructed by the presser 10, and in this state, the hand-cut shell culm is supplied to the clamping and conveying device 5, and the supply shell is By folding the base side of the culm downward, the hand-cut husk culm can be supplied to the holding and conveying device 5 very simply and reliably.

FIG. 4 shows another aspect of the configuration for changing the position of the presser 10, in which the position B of the presser 10 removed from the clamping surface of the clamping and conveying device 5 is on the handling cylinder side and the back surface thereof with respect to the clamping surface. It is configured so that the holding device 10 is not located in the middle of the holding path of the hand-cut husk culm, and the locking portion of the clamping and conveying device 5 is kept small while the amount of positional change of the holding device 10 is small. 14
, 14 further ensures secure transportation.

Note that the presser 10 may be pivoted to the tip guide 11, or may be pivoted to another member or provided so as to be freely movable in parallel.
