Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for discharging a pile of cut straw in a combine harvester.

In other words, in a combine harvester with a horizontally elongated straw cutter attached to the rear of the machine, the cut straw that falls to the ground from the straw cutter can be piled up in a well-ventilated pile, allowing for better drying. In addition, it is convenient to leave it in a pile and collect it with a baler, etc., and when the machine moves backward, it can be raised in conjunction with the raising of the reaping part to prevent damage. It is provided so that it can be implemented.

Next, the embodiment shown in the drawings will be described.

Fig. 1 shows a side view of the combine harvester.In front of the threshing section B mounted on the machine body supported by both crawlers 2, there is a hydraulic cylinder 3 that rotates around defect 0.
A cutter case 4 is equipped with a reaping part A that can be moved up and down by the machine, and each disc blade is fitted on two parallel axes inside a cutter case 4 which is connected to the rear of the threshing part B, which is the rear of the machine. A horizontally elongated straw cutter C is installed, and a straw removal chain 5 is extended from the rear upper part of the threshing part B to the upper part of the straw cutter C, and the structure is similar to the conventional structure.

A plate-like body 1 is installed in series at the rear lower part of the machine body below the straw cutter C, and the plate-like body 1 is a long plate that becomes slightly smaller in the front and rear direction, and has an inverted V-shaped mountain shape in cross section. The middle part of the support frame 6, which is bent and formed as shown in FIG.
The rear end of a wire 11, which is pivotally supported via the guide wheels 9 and 10 which is pivoted at the lower part of the threshing part B, is connected to the upper end part of the support frame 6, and a wire 11 is connected to the upper end of the support frame 6, The front end of the wire 11 extending from the front guide ring 9 is connected to the intermediate portion of the provided transmission and support pipe 12 via a connecting piece 13.

Therefore, during work, with the reaping section A lowered and moving forward, as shown in FIGS. 1 to 3,
Due to its own weight, the plate-shaped body 1 descends until it approaches the ground and is indexed, and then the straw cutter C
The cut straw that is cut into short lengths and falls as shown by arrow A forms a heap above the plate-like body 1 as shown in Fig. 5, and the plate-like body 1 is indexed forward and falls into the heap as shown in Fig. 5. After the straw leaves the cut straw, the inside of the cut straw remains hollow, which accelerates drying, and if it remains piled up, it is difficult to collect it using a baler, etc. It becomes easier to do.

When the machine moves backward, the hydraulic cylinder 3 raises the reaping section A, but in this state, the wire 11 is pulled forward as shown by the arrow B, as shown in FIG. will be raised as shown by arrow C, and for that purpose,
This means that the aircraft can retreat without the plate-like body 1 coming into contact with any obstacles.

In this way, the present invention provides a combine harvester in which a horizontally long straw cutter C is connected to the rear of the machine, and a plate-shaped body 1 having a chevron-shaped cross section is installed at the rear lower part of the machine below the straw cutter C. Since these are arranged so that they move up and down in conjunction with the up and down movement of the reaping part A at the front of the machine, the cut straw falling from the straw cutter C is thrown over the chevron-shaped plate-like body 1 and piled up. Therefore, when the plate-shaped body 1 is indexed by the machine and comes out, a cavity is formed inside the pile of cut straw, which accelerates drying. ,
In addition, since it is in a heaped shape, collection with a baler or the like can be carried out well.Moreover, when the machine moves backward, the plate-like body 1 rises as the reaping part A rises, which prevents damage to the machine body. This means that the vehicle can be moved backwards safely, and has the advantage of being able to be carried out suitably.
