JPS591446B2 - Grain culm conveying device in combine harvester - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is characterized in that within the conveyance path range of the primary clamping and conveying device for adjusting the handling depth, the sugar portion is pulled downward from the upper sugar portion conveying device. By providing a guide rod along the lower side of the movement trajectory of the tip of the conveyance claw of the conveyance device, the downward load applied to the conveyance claw is received, and a portion corresponding to the secondary clamping conveyance device on the conveyance terminal side is provided. In order to change the posture of the culm to a nearly horizontal state, a guide rod is provided along the upper side of the conveying claw to widen the width of the conveying path and to smoothly change the posture. It is.

The present invention will be described below based on an embodiment shown in the drawings. A lifting device 1 is provided obliquely at the front of the machine body, and a clipper type reaping device 2 is provided near the ground at the back of the device. A scraping guide device 3 is provided.

Reference numeral 4 denotes a raking and conveying device that rakes and conveys the base of the harvested husks a certain distance backwards.After taking over from this raking and conveying device 4, a primary clamping and conveying device 5 transfers the cut husks in an upright position. The structure is such that the culm is further transported to the rear and delivered to the next secondary clamping and conveying device 6 near the end thereof, and the terminal end of the secondary clamping and conveying device 6 is connected to the foot of the threshing device 7 mounted at the rear of the machine. It is located near Chain 8.

The secondary clamping and conveying device 5 is configured to be able to swing in the left-right direction around the axis P on the starting end side to adjust the handling depth.

Above the primary and secondary clamping and transporting devices 5 and 6, a joint engagement transporting device 9 for engaging and transporting the tip side of the culm is disposed, but within the range corresponding to the secondary clamping and transporting device 5, , transport claw 1
A guide rod 11 is provided along the movement locus of the tip of the conveyance claw 10, and a guide rod 12 is provided below the conveyance claw 10. 10 is arranged opposite to the upper side.

Since the present invention is configured as described above, when the machine body is moved forward while operating a predetermined device, the culm is pulled up by the pulling device 1 and cut by the reaping device 2. 3 and the scraping conveyance device 4, it is transferred to the starting end of the primary clamping conveyance device 5 and the contact portion engagement conveyance device 9 in an upright position, and is conveyed rearward and upward.

In this transportation process, the stock part is transferred from the primary clamping and transporting device 5 to the secondary clamping and transporting device 6, but the tip side part is still held and transported by the sugar part transporting device 9 while being supported by the guide rods 11 and 12vc. Then, near the end of these, the culm is changed to a nearly horizontal position, and the root part is transferred from the secondary clamping and conveying device 6 to the foot chain 8 of the underchain type, and the root and the tip side are transferred. The grains fall from the end of the sugar transport device 9 onto the lower inlet funnel and are supplied into the handling chamber where they are subjected to the threshing action.

If there is a difference in the length of the shell culm, by changing the swing of the primary clamping and conveying device 6 around the axis 2 on the starting end side, the relative position with respect to the secondary clamping and conveying device 5 changes and the culm is By changing the gripping position of the threshing device, the handling depth to the threshing device can be adjusted to the optimum state. Within the range of the clamping and conveying path, the downward pulling action of the culm is performed on the sugar section engaging and conveying device 9, so that the conveying claws 10 that are holding and conveying are subjected to a downward pulling load. However, as the guide rod 11 attached to the lower side absorbs the load, it is possible to reliably carry out stable and stable conveyance without strain.

In addition, since the part corresponding to the secondary clamping and conveying device 6vC has almost no action to pull out the husk culm, and only tilts the husk culm, by arranging the guide rod 12 opposite to the upper side of the conveying claw 10, , the conveyance route space is widened, the posture can be changed smoothly, and the grain can be fed to the threshing device in an orderly manner.

In short, according to the present invention, the reaped husk culm in an upright position is transported rearward by the primary clamping and conveying device and delivered to the next secondary clamping and conveying device near its terminal end (vc), and the above-mentioned - next In a combine harvester configured to adjust the handling depth by swinging the clamping and conveying device around its starting end,
A sugar section engaging and conveying device is provided above the secondary and secondary clamping and conveying devices, and a guide rod that follows the moving trajectory of the tip of the conveying claw of the sugar section engaging and conveying device corresponds to the secondary clamping and conveying device. The part corresponding to the secondary clamping and conveying device is located below the conveying claw, and the portion corresponding to the secondary clamping and conveying device is positioned above it, so that the culm cannot be pulled out by the sugar part engaging conveying device at the conveying speed. Even if the load is applied to the conveyor jaws, the load on the conveyor jaws can be absorbed by the guide rod, ensuring a reasonably stable conveyance operation.In addition, the threshing device Appropriate posture changes can be easily and smoothly performed.
