Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a second cutting blade device in a two-stage secondary combine harvester, specifically, a second cutting blade device for stock preparation in addition to a first cutting blade for cutting culms. Then, the culm cut with the first cutting blade is passed through a feeder house, for example.

The present invention relates to a two-stage sub-product combine harvester in which the cutting blade is fed to a single handling cylinder, and the uncut stock base can be trimmed using a second cutting blade.

Prior Art Conventionally, as seen in Japanese Utility Model Application Publication No. 49-70043, a cutting blade for cutting the tip of the culm was provided at the front upper part of the platform, and a cutting blade for cutting the root was placed at the lower part of the platform to remove the tip of the culm. There is a two-stage sub-harvester combine harvester in which only the culm part is carried into the machine, and the culm trunk is cut down from the base.

Problems to be Solved by the Invention In the above-mentioned two-stage secondary combine harvester, a cutting blade for cutting the tip and a cutting blade for cutting the root are provided in the feeder house. When adjusting the cutting height of the cutting blade according to the height of the culm, when the feeder house is raised and lowered, the cutting blade for root cutting also goes up and down, and if the cutting height is high, the roots of the remaining stumps will be removed. The disadvantage is that the height of the part is also high, making it difficult to cultivate.

Means for Solving the Problems Therefore, the technical problem of the present invention is to provide a combine harvester in which the height of the uncut plants is always kept constant regardless of the cutting height. .

The technical means of the present invention to solve this technical problem is to provide a two-stage secondary combine that is equipped with a second cutting blade for cutting alignment in addition to a first cutting blade for cutting culms. is installed in the running section, and its blade edge is positioned between the cutting section consisting of the first cutting blade and the running section.

Effects of the Invention The present invention achieves the following effects by employing the above-mentioned technical means.

In other words, since the second cutting blade is attached to the running section, its relative position to the ground is unrelated to the cutting height of the cutting section.
In order to improve work efficiency in a full-feed combine harvester, it is possible to completely cut down the base of the stock that remains uncut when high mowing work is performed.

In addition, since the second cutting blade is located between the reaping part and the running part, it is not only possible to cut down the base of the stock before it is stepped on by the crawler tires, but also the second cutting blade is located near the idler part of the crawler. It has the characteristic that it is not easily affected by the pitching of the aircraft.

In addition, when the reaping section is in the raised state, that is, when traveling on the road, the frame of the second cutting blade also serves as a stopper for preventing the reaping section from coming down, and also allows the reaping section to be stored in a safe position.

Example The following description will be made based on the embodiments shown in the drawings.

First, the entire combine harvester equipped with a screw-type threshing machine will be explained.

The culm is scraped in by a scraping reel (1) and cut by a cutting blade (2), and the cut culm is transferred from a scraping auger (3) to a chain conveyor (5) in a feeder house (4) to a handling room. The grain is transported to (6) and threshed using a complete screw handling cylinder (7).

The threshed grains fall from the receiving net (8) onto the rotating auger (9), and the rotating auger (9) moves the straw toward its terminal end, and the straw is discharged from the culm opening (6a). .

During this conveyance process, grains and fine straw waste fall downward from the receiving net (10) stretched over the receiving gutter of the auger (9), and only the long straw is carried toward the culm opening (11).

Leakage including grains that have fallen from the receiving net (10) is carried by a conveyor (12) toward the gutter, and is subjected to sorting air from the end of the conveyor (12) by a fan (13) like a winnower. The grains are placed in the first m (15), and the second items are placed in the second gutter (14).
) and the grains that fell into the first gutter (15) are transferred to the grain barrel (
17) to the paddy tank (20), and the second grain is returned to the handling room (6) by the return conveyor (18).

(21) is a crawler equipped with a thresher, and (22)
is the lift cylinder of the feeder house, (23) is the divider, and (24) is the driver's seat.

The present invention provides a combine harvester as described above, in which a fourth cutting blade for cutting down the base of the stock is arranged in the running section.

That is, (25) is the main frame of the running section, to which the base of the cutting blade frame (26) is attached, and its position corresponds to the front surface of the threshing section.

Also, connect the left and right joint pipes (28) of the trunk frame (27).
) is provided with a hydraulic cylinder (29), which swings the cutting blade frame (26) about a shaft (30) to raise and lower the cutting blade.

Then, the mounting bracket (34) of the rond (33) is attached to the eccentric position (32) of the crank plate (31) attached to the shaft (30).
is attached, and the tip of the rondo (33) is pivoted to one arm (35a) of the bell crank (35).
A drive arm (36) for the cutting blade (37) is pivotally supported on the other arm (35b) of the bell crank (35). (
38) is the pivot point of the bell crank (35).

Due to the above-described structure, when the crank plate (31) is driven via a drive device (not shown), the iron (33) moves up and down and swings the bell crank (35).
) The movable blade moves left and right relative to the fixed blade.

As described above, since the second cutting blade (37) is attached to the running section, it moves up and down along with the running section, and its relative position to the ground always maintains the base of the stock at a constant level even if the cutting height of the cutting section changes. You can cut it down and go.

To adjust the position of the second cutting blade, use the hydraulic cylinder (
29) to adjust the elevation. It should be noted that the device of the present invention can also be applied to combine harvesters other than the embodiments.
