Description

[Detailed description of the invention] This invention is attached to the front part of the cutting blade of a reaping machine such as an agricultural combine harvester or an agricultural binder to raise the planted stem culm to an almost vertical position during work. The suspended winding is an endless rotating body, and when moving from a position near the ground to an upper position, it protrudes laterally from the case to arch the planted stem culm.
In addition, when moving from an upper position to a position near the ground, a raising claw that is retracted into the case is installed, and
Regarding the stem culm pulling device for a reaping machine, the straw waste is brought into the case by the lifting claw, and the straw waste is brought into the case by the lifting claw, and the straw waste is discharged from the outside. A function to release straw waste etc. to the uncut land side and prevent it from being pulled up again and brought into the case during subsequent reaping of the uncut culm, and a function to prevent the straw waste from being brought up into the case again, and to prevent the straw waste from being brought up into the case, etc. The aim is to make it possible to combine the safety functions with simple configuration additions.

That is, the stem culm pulling device for a reaper according to the present invention, in the above-mentioned device, is located at the lateral outer side of the case, and
At a location opposite the discharge port at an appropriate interval, the straw waste discharge port has a vertical length from a position opposite to the straw waste discharge location to near the ground, and a front-to-back width extending from the lifting case to the rear reaping device. A plate-like cover is provided to cover the side of the aircraft body so as to guide the straw waste not released from the discharge port in a direction along the traveling direction of the aircraft body, Straw waste, which is brought into the case by the claws and released laterally outward from the outlet at the top of the case, can be guided along the plate-like cover while being separated from the uncut land side. There is no inconvenience of releasing it to the ground and bringing it back into the hoisting case, and it can be released onto the mown field, and the plate-shaped cover can also be used as a safety cover for the hoisting device, reaping device, etc.

Therefore, the present invention has been developed for a reaper with a simple structure, which has both an effective guide function for releasing straw debris brought in by the pulling claw into the mown field, and a safety function for the pulling device, the reaping device, etc. We have now been able to provide a stem culm pulling device.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a combine harvester, which is an example of a reaping machine, and the combine harvester is equipped with a front end of the machine body equipped with a crawler type traveling device 6, and a planted culm reaping pretreatment section 7 that is biased left and right.
At the same time, a threshing section 8 is mounted at the rear of the machine, and a cut husk conveying section 9 and a driving section 1 are installed between these two sections 7 and 8.
The cut husk culm conveying section 9 is located at the rear of the pre-processing section 7 and is arranged in parallel on the left and right.

As shown in FIGS. 2 to 4, the preprocessing section 7
Support rod 11 in a posture along the direction of aircraft movement...
A weeding tool 12 is provided at the front end of the
A hair clipper is provided, which is equipped with a pulling device 14 that locks, pulls up and conveys two separated planted culms along a common route 13 and raises them into an almost vertical shape, and also cuts the base of the raised culm. A mold reaping device 15 is provided.

The lifting device 14 has a pair of left and right lifting cases 1, 1 forming the common lifting path 13 between them, which are installed diagonally across a position near the ground and a rear upper position in the traveling direction. At the same time, hoisting chains 2, 2 (winding is an endless rotating body) are rotatably hung in these hoisting cases 1, 1, respectively, and a shell culm is attached to these hoisting chains 2, 2 husbands. It is constructed by attaching lifting claws 3, 3, . . . for locking and conveying.

The lifting claws 3, 3... are connected to the common lifting path 1.
3 from a position close to the ground toward a rearward and upper position, the culm protrudes from the case 1 to the common pulling path 13 on the side and is designed to lock and transport (raise) the planted shell culm. At the same time, when moving from a rear upper position to a position near the ground, it is retracted into the cases 1 and 1.

In the figure, 16 is located on the lateral outer side of the fuselage of the lifting case 1 located on the uncut culm side among the lifting cases 1, 1, and is used to drive the lifting chain 2 in the lifting case 1. 17 is connected to the upper end of the pillar-cum-cylindrical transmission case 16, and drives the pulling chains 2, 2 of the left and right lifting cases 1, 1. It is a cylindrical transmission case with a transmission shaft inside.

Thus, the lifting device 14 has the lifting claws 3...

. . . Attached and erected, the carry-on is opened laterally outward at a position facing the plate-like cover 4 at an appropriate distance from above the draw-up case 1 with this cover 4 attached. The straw waste discharge port 5 is shaped to receive the straw waste brought into the case 1 due to the lifting action and released from the discharge port 5, and the straw waste is delivered along the cover 4 to the uncut land side. The configuration is such that the aircraft is guided in a direction along the direction in which the aircraft is traveling in a state where the aircraft is blocked.

A straw waste discharge port 5' that opens laterally outward is also formed at the upper part of the other lifting case 1, and the upper parts of the picture raising cases 1 and 1' are connected to these from above. , a connecting case 19 that covers the connecting case 19 with its lower end positioned below the discharge ports 5, 5' and forming a downward passage for the discharged straw waste between the discharge ports 5, 5'. It is connected through.

Further, the upper edge of the plate-like cover 4 is connected to the lower edge of the connecting case 19 in a slightly overlapping manner, so that
The portion 4b of the plate-shaped cover 4 that faces the outlet 5 is constituted by the portion of the connecting case 19 that faces the outlet 5.
