2. Description of the Related Art As a conventional technique, a treatment chamber is provided in parallel in a treatment chamber, and the treatment chamber and the treatment chamber are communicated with each other to perform threshing treatment. For example, Japanese Utility Model Laid-Open No. 57-129332 or The one disclosed in JP-A-59-166628 is generally known.

[0003]

Conventionally, a mowing grain culm becomes an ultra-short culm by cutting the corner of an agricultural field with a high height, and the culm is clamped by a grain-culling pinching and lateral feeding device and placed in a handling room. If it is fed laterally, it will be left untreated.In that case, the entire amount of grain culms should be supplied to the handling room.However, if the entire amount of grain culms is supplied to the handling room, the threshing load is increased and the handling is increased. The rotation speed of the barrel will decrease, the threshing capacity will decline, and it will also affect the sorting performance of the wholesale products. Therefore, the present invention does not increase the threshing load when threshing treatment is performed by supplying the whole amount of such grain culms to the handling room, and reduces the stab grain discharged together with the straw. It was created for the purpose of providing a product that can reduce losses.

[0004]

As a means for achieving the object described in the preceding paragraph, the present invention has a treatment room arranged in parallel in the treatment room and threshing treatment is performed by each chamber. The discharge from the open dust delivery port is sent to the middle part of the processing chamber, the part from the dust delivery port of the processing chamber to the edge of the processing chamber is communicated with the handling chamber, and the communication part with the handling chamber is a partition wall. The opening / closing switching means of the partition wall and the pinch releasing means of the grain stalk pinching and lateral feeding device provided along the handling chamber are operated in cooperation with each other.

[0005]

With this structure, the culm culms in the reaping unit are conveyed to the threshing unit by the conveying mechanism, and the roots of the stock are passed to the grain-scattering and lateral feeding device of our grain and threshed in the handling room. With
Emissions from the dust inlet of the handling room will be processed in the processing room, and when threshing ultra-short culm by high-cutting, the grain will not be left in the handling room so as to prevent leftovers. The whole amount of culm is supplied, but in this case, when the grain culm pinching and lateral feeding device is operated by the pinching releasing means, at the same time, the opening and closing means is interlocked to move the partition wall to move from the dust port of the processing chamber. Opening the communication part with the handling room at the start end, discharging the thing in the handling chamber to the start end of the processing chamber early to share the threshing action, disperse the threshing load and suppress the increase in the threshing load. The processing capacity is not reduced, and the early discharge into the processing chamber causes the inside of the handling chamber to become coarser, reducing the number of sessile particles discharged together with the straw.

It is designed so that the cutting process is performed at.

[0007] The grain culm pinching and lateral feeding device (5) is of an under-chain type, in which a pinch rail (18) is elastically installed above the feed chain (17). The feed chain (17) is extended forward to extend the extension (1
7a), and the transport action of the vertical transport chain (19), which is responsible for the transport later of the transport mechanism (13) of the mowing section (B), has a holding frame (20) as shown in FIG. The clamping rails (21) supported by (1) are pressed against each other and cooperate with the vertical transport chain (19) so that the culms of the harvested grain culms can be lifted even if they clamp the waft. A grain culm pressing rod (22) is extended from the extension part (17a) of the feed chain (17) from the (20), and the grain culm pinching and lateral feeding device (5) is fed from the end part of the vertical transport chain (19). It is because the 翈 元 inherits the wa.

Further, as shown in FIG. 1, a sensor (S) for detecting the culm of the cut grain culm is provided at the lower part of the vertical transport chain (19), and a sensor (S) is provided at the upper part of the vertical yard. 2 different positions
Two sensors (S1) and (S2) are provided, and when the sensor (S) detects the grain culm “existence”, the sensors (S1) and (S2) of the upper crocodile are both If detected, it means that the grain culm is a long culm, so the vertical transport chain (19) is adjusted to a shallow handle, and the low-rank sensor is used.
If (S1) detects and the high-order sensor (S2) does not detect, it is determined that the grain culm has a standard length, and the vertical transport chain (1
The operation depth is adjusted to the standard by the operation of 9). Then, when the whole cutting unit (B) is moved up about the fulcrum (P) to perform high cutting, the cut culm becomes an ultra short culm and the sensor (S) of the culm is a grain culm. The two sensors (S1) and (S2) whose tips are to detect but not to detect are set so as not to detect.

Next, the pinch rails (18) constituting the grain-crop pinching and lateral feeding device (5) are formed by connecting the rail pieces in a chain form to the motor shaft of the control device (M). Actuating arm (2
4) The base end of 4) is pivotally attached, and the operating arm (24) of the first and second pressing rods (25) (25) has the starting end of the pinching rail (18). The upper ends are connected to each other so that the motor shaft (23) can be rotated upward with the third pin shaft (26) as a fulcrum by the rotation of the motor shaft (23) as shown by arrow (a). 17) is provided with a pinch releasing means (Y) separated from it.

Then, each of the above sensors- (S) (S1)
(S2) is electrically connected to the control device (M), and the sensor (S) of the culm is detecting the grain culm, and the two sensors (S1) and (S2) of the tip of the culm are not both detecting. When the so-called cut culm is a very short culm, the detected information is used as the control device (M).
And the motor shaft (23) is rotated via the device (M) to activate the pinching release means (Y).

Further, as shown in "FIG. 1" and "FIG. 3",
The culm of the handling chamber (1) communicates with the middle part of the treatment chamber (2) through the dust inlet (3) to treat the discharge from the dust inlet (3). Dust port (3) in chamber (2)
The part from the part to the starting end is communicated with the handling chamber (1), and the communication part (W) is opened and closed by the movable partition wall (4).

In order to move the partition wall (4), two guide members (27) (2) having a U-shaped cross section are used.

The control motor (29) of the open / close switching means (X) is connected to the control device (M),
When each of the sensors (S) (S1) (S2) detects that the harvested culm is an ultra short culm and operates the clamping release means (Y), the open / close switching means (X) also has a control device (M). A command is issued from the above to move the partition wall (4) upward to open the communication part (W), and the opening end closing switch means by the return movement of the start end of the pinch rail (18) by the pinch release means (Y). (X) is also a partition (4)
Is moved downward to close the communication part (W).

Therefore, when the harvested grain culm is an ultra short culm as described above, the clamping release means (Y) is activated to operate the clamping rod (1).
When the starting end of 8) is rotated upward as in (a) and the lateral feeding by feeding with the feed chain (17) is released and the whole amount of grain culms is supplied into the handling chamber (1) and threshed, At the same time, the opening and closing means (X) works together to move the partition wall (4) upward to open the communicating portion (W). Then, as shown by the arrow (b), the inside of the handling chamber (1) is discharged early to the starting end of the processing chamber (2), and the processing chamber (2) shares the threshing action and smoothes the threshing process. In addition, the early discharge to the processing chamber (2) causes the inside of the handling chamber (1) to become rough and become stuck grains, and the grains discharged outside the machine together with the straw are reduced.

When the cut grain culm has a standard length or a long culm, the pinch releasing means (Y) does not operate and the feed cullet (17) and the pinch rail (18) pinch the grain culm laterally. In order to carry out threshing treatment, the partition wall (4) closes the communicating part (W) and the treatment chamber (2) is discharged from the dust outlet (3) of the waste culm of the handling chamber (1). Treat the effluent.

Further, when the partition wall (4) for opening and closing the communication portion (W) is opened by moving upward,
The part of the partition wall (4) that has moved up is housed and gathered in the space along the back part of the handling room (1) and does not interfere with other members to affect each function.
