Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a threshing culm cutter that directly cuts the threshing culm that has been threshed and culled by a threshing device using a cutter.

Conventionally, a cutter has a configuration in which a number of cutting blades are arranged on a pair of parallel rotating shafts at appropriate intervals in the axial direction, and the threshing culm is fed to the cutting section in parallel with the rotating shafts and cut. In this case, if the culm of the discharged culm is difficult to be parallel to the cutting part, and a part of the culm is fed in first, and the stock base side and the tip side are delayed, the part that was fed in first will be in contact with the cutting blade. As the disk rotates, it is rapidly drawn in, and the culm body is drawn out at right angles to the axis of rotation without being sent into the cutting section even though the part that lags behind, such as the stem end or the tip end, is pulled out. However, the cutting length tends to change significantly, and in severe cases, the cutting performance is unstable, such as being discharged uncut.

This invention eliminates these deficiencies.

For this reason, the present invention has the following configuration.

That is, in a culm removal device for discharging the threshed culm 2 threshed by the threshing device 1, the stock source of the culm 2 is The transfer speed of the stock head and head culm removal devices 4, 5 that transfer the side portion and the tip side portion is increased, and the transfer end portion of each stock head and head culm removal device 4, 5 is transferred to an intermediate culm removal device. The cutter is extended longer than the transfer end of the culm removal device 3 and has a large number of cutting blades 8, 9 disposed on the rotating shafts 6, 7 in the direction along the culm of the culm 2 at the transfer end of these culm removal devices. The structure of the threshing culm cutter is made to look into the cutting part 10.

In addition, in the drawing, the threshing device 1 includes a handling barrel 11 installed in a handling chamber and rotated in conjunction with each other, and a stock head transfer device 12 is provided along one side of the handling room, and grain culms to be transferred by the stock head transfer device 12 are provided. 2
The structure allows the tip of the grain to be fed into the handling chamber for threshing.

Reference numeral 13 denotes a receiving plate, which is formed horizontally on the upper surface of the machine frame 14 on the rear side of the handling room, and on the upper side of the receiving plate, the chain of the intermediate culm ejecting device 3, which is a culm ejecting device, is mounted diagonally from the rear side of the handling room to the rear side of the tip side. The chains are installed in two parallel rows with appropriate spacing in the direction of the culm force, and the chain on the panicle side has two chains in front and back that are interlocked.

In this way, the intermediate culm shedding device 3 is constructed using this chain and the receiving plate 13.
The structure is such that the middle part of the culm 2 can be held and transferred between the culm and the culm.

The head culm removal device 4 and the tip culm removal device 5 are located on the plant head side and the tip side of the clamping position of the intermediate culm removal device 3, with the upper surface of the lug belt slightly protruding from the upper surface of the receiving plate 13. The front ends of these belts are stretched between the shaft 15 of the rear half of the intermediate culm evacuation device 3 and the rotating shaft 7 on the lower side of the canoter, and the evacuation culm 2 is placed on the upper surface and transported. This is a possible configuration.

The transfer speeds of the stock head and tip culm removal devices 4 and 5 are appropriately set higher than the transfer speed of the intermediate culm removal device 3.

The rotating shafts 6, 7 are supported on a cutter frame 16, and the cutting portions 10 of the cutting blades 8, 9 disposed on the respective shafts 6, 7 are directed toward the culm force of the culm 2 at the terminal end of the culm ejecting device. The cutter frame 16 is provided horizontally along the machine frame 14, and the cutter frame 16 is detachably attached to the machine frame 14.

The cutting blade 8 of the rotating shaft 6 has an outer periphery shaped like a star foil, with a groove formed in the direction of the rotational force, and the cutting blade 9 of the other rotating shaft 7
The cutting portion 10 is cut by inserting the blade edge formed on the outer periphery into this groove.
It constitutes.

17 is a resistance rod, which faces the terminal end of the intermediate culm removal device 3;
The upper side part is fixed to the cover 18, and the lower free end part is curved toward the rear force, so that an appropriate transfer resistance can be applied to the intermediate part of the culm 2.

Reference numeral 19 denotes an interlocking shaft which interlocks the stock transfer device 12, intermediate culm expulsion device 3, etc., and interlocks and rotates the rotary shaft γ of the cutter via a belt 20 and the rotary shaft 6 via a gear 21. It is.

The culm 2 threshed by the threshing device 1 is held and transferred by the intermediate culm removal device 3, but in the latter half of the process, the stock culm removal device 4 and the tip culm removal device 5, which rotate at higher speeds, remove the culm from the culm. In order to transfer the stem part and tip part of the culm, the culm body of the culm 2 is changed into a dogleg shape so that the stem part and tip part are transferred earlier than the middle part, and the culm is cut. It is transferred and supplied to the section 10.

The culm 2 whose stock part and tip part are supplied to the cutting part 10 is about to be drawn toward the stock part and the tip side, and the whole part of the culm is drawn toward the cutting device 10 side, thereby improving the cutting action. The cutting length is unlikely to change due to pulling the culm into either the stock side or the tip side, and the transfer end between the stock base culm removal device 4 and the tip culm removal device 5 reaches the cutting section 10. Because of the intervention, the supply to the cutting part between the stock base and the tip of the Yoshi tip is reliable, and the above-mentioned effect is further stabilized.

Since this invention has the above-mentioned configuration, the culm threshed by the threshing device is used as the source of the old stock of the intermediate culm device.

At the terminal end of the culm, which is discharged by the culm tip removal device, the stock base and the tip of the culm are moved faster than the middle part of the culm, and the discharged culm is fed to the cutting part in a dogleg shape. The part cutting tip part is the part that is reliably transferred from the transfer end of the intermediate culm ejecting device to the cutting part, so the culm body is cut while being pulled by both the plant base side and the panicle tip side during the cutting action. , it is less likely to cause changes in cut length or uncut parts.
