Description of the Related Art In a conventional self-removing combine, a planted grain culm is cut by a cutting portion at a front end of a machine body, and the cut grain culm is arranged to be opposed to a feed chain in a threshing apparatus by a vertical conveying device. The harvesting culm is clamped and transported by a clamping and conveying device consisting of a clamping rail and is handled and transported. The change in the culm length of the planted grain culm is detected by a culm length detection sensor. A configuration for performing a handling depth adjustment control to change the holding position by the vertical transport device in the culm length direction based on the result has been adopted (for example,
See JP-A-4-365420].

いる。However, in the above-described conventional configuration, when the length of the transported grain culm is extremely short, even if the vertical transport device is controlled to move to the deepest handling side, the holding position by the feed chain is not affected. There is a possibility that the distance from the grain to the grain portion of the culm becomes short, and the grain portion of the grain culm may pass through a region that cannot be handled by the handling cylinder rotating in the handling room. In particular, in the mowing work near the ridge, the mowing work is performed while raising the mowing part in order to prevent the divider at the front end of the machine from coming into contact with the ridge. As a result, the above-described problem occurs, and the problem of unhandled portions occurs. An object of the present invention is to eliminate the above disadvantages.

ることになる。The threshing device 3 is a device for holding and transporting the harvested culm.
0, the spike side is handled by a handle drum 3b that is driven and rotated in a handling chamber 3a while holding the stock side, and threshing work is performed. A threshing operation state switching means A is provided which can be switched between a state in which the feed chain 12 clamps and transports the grain culm and a state in which the transported grain culm is thrown into the handling room. And a granulated state detecting means B for detecting that a granulated portion of the transported cereal stem is present in a set area up to a point reaching a set distance toward the ear tip side, wherein the granulated state detecting means B is provided. When the detection state is reached, the threshing work state switching means A
Is automatically switched from the state in which the grain culm is held and transported by the feed chain 12 to the state in which all culms are loaded. More specifically, one of a plurality of guide rods 15 that support the holding rail 13 is provided so as to be capable of ascending and driving by an electric motor 25 via a link mechanism 24, and is provided at a lower working position and at a higher working position. It is configured so that it can be switched to the position where it retracts to release the grain stem holding state. Therefore, by switching the guide rod 15 to the pinch release position, the cereal stalks being conveyed at the relevant position are fed chain 1
2 and the holding conveyance by the holding rail 13 are released, and the whole is drawn into the handling room. That is, the electric motor 25 for pinching release constitutes the threshing work state switching means A. Then, as shown in FIGS. 1 and 4, an image pickup device 31 for judging the set state of the transported grain culm before being carried into the handling room 3 a is installed, and an image taken by the image pickup device 31 is used. For example, as shown in FIG. 5, image processing is performed to determine whether or not a grained portion of a transported grain culm exists in a setting area Q from a location to be set to a tip end side from a location to be held by the nipping and transporting device 10. A control device 23 for making a determination based on control or the like is provided. When the control device 23 detects that the grained portion of the transported cereal culm exists in the area, it releases the pinching after a predetermined transport required time has elapsed. The electric motor 25 is driven to switch the guide rod 15 from the clamping operation position to the clamping release position. That is, the image pickup device 31 and the control device 23 constitute the particle size detection means B. As a result, for example, when the mowing work is performed in the vicinity of the ridge, when the mowing work is performed while detouring upward so that the weeding implement 6 does not contact the ridge, the cutting height is increased and the length of the cut culm is short. However, in such a case, it is possible to prevent the occurrence of the unhandled state due to the state in which all the culms are put in.

2 may be set in the latter half of the nipping transport path. By doing so, the handling process in the handling room 3a is almost performed at the front end of the transport path, and the handling process load is reduced in the latter half, so that the threshing work load becomes excessive with the introduction of all culms. Can be suppressed.

In other words, as shown in FIG. 8, a plurality of potentiometer-type layer thickness detection sensors S for detecting the layer thickness at predetermined small intervals along the culm length direction with respect to the grain culm to be conveyed are arranged, and each of these detections is performed. The boundary between the grained portion and the stem portion of the grain culm to be conveyed is determined from the result, and it is detected whether or not the root end of the grained portion determined in this way is within the set area Q. May be configured.

As shown in FIGS. 6 and 7, at the delivery point from the vertical transport device 11 to the feed chain 12, the grain culm being delivered is forcibly pulled out, and all the culms are scraped and transported to the handling port 3 c of the threshing device 3. Although a crank type scraping device 27 is provided and an electromagnetic clutch 28 is interposed in a transmission system for the crank type scraping device 27, the electric motor 20 for adjusting the handling depth is driven to the deepest handling side. Instead, when the short culm side detection sensor 21 detects the absence of grain culm, the control device 23 controls the electromagnetic clutch 28 to switch from the disengaged state to the engaged state after a predetermined required time for conveyance, A short grain culm may be introduced into all culms so that no untreated residue occurs. In this case, the threshing operation state switching means A is constituted by the crank type scraping device 27 and the electromagnetic clutch 28. As shown in FIG. 9, a disk cutter 29 for cutting the transported grain culm is provided in the vicinity of the handling room side of the feed chain 12 so as to be vertically movable by a slide mechanism 30, and the extremely short culm as described above is detected. If
The slide mechanism 30 may be configured to control the slide mechanism 30 to switch to a cutting position in which the grain culm is cut from the position where the disk cutter 29 is retracted downward and almost all culms are put into the handling room.
The disc cutter 29 and the slide mechanism 30 constitute threshing work state switching means A.
