Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a culm feeder for a cutter that cuts the culm discharged from a threshing device with rotary blades arranged at appropriate intervals on a rotating shaft substantially parallel to the culm direction. Regarding the device, the waste culm body is stretched and fed to the cutting section, so that the cutting is performed accurately at the axial intervals of the rotary blades, and the cutting efficiency is improved.

The culm discharged from the culm discharge port of the threshing device tends to be discharged later on the ear side, and the culm discharged from the culm discharge port is further transported by holding approximately the center of the culm body. In such cases, the transfer of the culm ends on the plant base side and the ear side tends to be delayed.

If the culm is fed to a cutter with rotary blades arranged at appropriate intervals on the rotating shaft, the culm at the end of the culm will be fed obliquely to the axial direction of the rotating shaft, and the culm will be rotated. The axial spacing of the blades will not result in cutting.

The trench and culm ends tend to float up, easily escape from the cutting action of the cutting blade, and are difficult to cut.

This invention is intended to solve the above-mentioned disadvantages, and is constructed as follows.

That is, from the transfer end of the waste culm transfer device 1 to the transfer end of the waste culm transfer device 1 that transfers the threshed waste culm, and the rotary shaft 3 on which the rotary blades 4 are arranged at appropriate intervals in the axial direction. The helical shaft 6, which is provided with a spiral protrusion 5 that is located on both sides or one side of the stem side and the tip side of the ejected culm and feeds the ejected culm from the middle to the end, is rotated as described above. The feeding device for a threshing culm cutter is provided with the axial direction parallel to the shaft 3.

The present invention achieves the following technical effects with this configuration.

That is, the culm transferred by the culm transfer device 1 is
From the end of the transfer to the helical shaft 6, it receives the feeding action from the middle part of the culm toward the end of the helical protrusion 5 provided on both sides of the stock side and the tip side of the culm, or especially on one side where the transfer is delayed. Then, the culm is stretched along the axial direction of the rotating shaft 3 and is subjected to cutting action by the rotating blade 4 disposed on the rotating shaft 3, so that the cutting dimension is accurate and effective cutting is performed. You will be killed.

Next, an embodiment of the present invention will be described with reference to the drawings. Reference numeral 7 denotes a combine harvester machine, and the culm transfer device 8 which holds the root of the husk and transfers it while threshing the head side with a threshing device. A discharged culm transfer device 1 is provided diagonally rearward toward the head side, and transports the discharged culm discharged from the discharge port of the threshing device.

This culm transfer device 1 is composed of an upper endless band 9 and a lower clamping rod 10, and pinches and transfers the culm of the culm.

Attach the cutter machine frame 11 to the rear side of the combine machine body 7,
The supply port 12 is directed upward, and the terminal end of the discharge culm transfer device 1 is provided to protrude above the supply port 12.

A helical shaft 6 is installed in the cutter frame 11 below the terminal end of the culm transfer device 1. In this embodiment, a spiral shaft 6 is provided from a position corresponding to the terminal end of the culm transfer device 1 toward the plant base side and the ear tip side. Then, the winding direction of the spiral protrusion 5 is reversed, and the unidirectional rotation of the helical shaft 6 causes a feeding action to be performed to stretch the stem side and the tip side of the culm toward their respective ends.

A pair of rotating shafts 3.13 are supported on the cutter frame 11 at the lower rear of the helical shaft 6.

A large number of rotary blades 4 having fine wave-shaped blade edges on the outer periphery are fixed to one rotary shaft 3 at regular intervals, and the other rotary shaft 1
3 is provided with a pair of scraping pieces with a small gap.
4 is fixed with the outer peripheral edge of the rotary blade 4 partially inserted into the small gap, and these rotating shafts 3.degree. 13 are rotated in opposite directions.

The culm discharged from the culm discharge port of the threshing device is transferred while being held between the endless band 9 and the clamping rod 10 of the culm transfer device 1, and is discharged onto the helical shaft 6 from the terminal end thereof.

By the rotation of the helical shaft 6, the culm body of the discarded culm is extended toward the plant base and the tip side by the helical protrusion 5 provided on the outer periphery, and the culm body is extended toward the stock side and the tip side.
It is fed into the opposing intersection of the rotary blades 4, cut, and discharged to the ground.

Incidentally, since the tip side of the culm tends to be easily delayed from being transferred and easily bends, the spiral protrusion 5 is arranged to feed the culm from the middle part of the culm to the tip end of the culm on the tip side. You may try to stretch it.

Further, the shell culm transfer device 8 may be made long so as to protrude above the cutter frame 11, and may also be used as the discharge culm transfer device 1, or the discharge culm transfer device 1 may be extended to the rear side of the cutter frame 11. , the culm may be discharged from the middle to the supply port 12 of the cutter.

Further, the combination of the cutter loading board 14 and the rotary blade 4 can be modified in various ways, such as by alternately fixing the rotary blade and the scraping board 14 to the rotating shafts 3 and 13.
