Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an example of a self-contained combine. The self-removable combine is attached to a body frame 2 supported by a pair of right and left crawler traveling devices 1 and 1.
It is equipped with a pre-cutting device 3, a threshing device 4, a boarding operation unit 5, a Glen tank 6, and the like.

The pre-cutting device 3 is, as shown in FIG.
Weeding tools 7 juxtaposed on the left and right, a raising device 8 for raising the culm weeded by the weaving device 7, a cutting device 9 for cutting the root of the culm caused by the raising device 8, cutting It is equipped with a vertical transport device 10 for transporting the grain culm rearward. Then, the grain culm transported by the vertical transport device 10 is delivered to the feed chain 11 of the threshing device 4 and transported rearward while threshing.

At the front end of the feed chain 11, that is, at the starting end of the conveyance, as shown in FIGS. 3 and 4, a grain culm supply guide 12 is placed laterally on the front end of the rail base 13A of the clamping rail 13 of the feed chain 11. It is pivotally supported around the axis P. The cereal stalk supply guide 12 holds the feed chain 11 in a holding action posture along the grain stalk transport direction and swings up from the holding action posture to open the front end of the feed chain so that the cereal stalk can be held. It is configured to be able to switch to the retracted position freely and to automatically maintain the position by being elastically biased to one position by a toggle mechanism (spring 14). A limit switch 15 as a pillow handling mode detecting means that is switched when the grain stalk supply guide 12 is in the retracted posture.
Is mounted on the rail base 13A of the holding rail 13 via a mounting bracket 16, and a switching signal of the limit switch 15 is input to the control device 17. In addition, the mounting bracket 16 is a grain stalk supply guide 1.
Reference numeral 2 also serves as a stopper when in the evacuation position.

As shown in FIG. 5, when the ON signal from the limit switch 15, that is, the switching signal when the cereal culm supply guide 12 is set to the retracted position, is input to the control device 17, as shown in FIG. Is provided. In the pillow handling mode state, as shown in FIGS. 3 and 4, the vertical transport device 10 is moved horizontally at a rear portion in order to further open the front of the transport start end of the feed chain 11. A forcible operation control unit 19 as a forcing depth operating means for outputting a drive signal for driving the electric motor 18 for adjusting the operating depth so as to be forcibly rocked downward around the axis Q and positioned at the deepest handling side. Is provided in the control device 17. A potentiometer 20 for detecting a swing angle of the vertical transport device 10 around the horizontal axis Q is provided, and a detection signal of the potentiometer 20 is input to the control device 17. The control unit 17 obtains a detection signal of the potentiometer 20 to obtain the original posture when the forcible operation control unit 19 forcibly changes the posture of the vertical conveyance device 10 to the deep grip, and obtains the horizontal axis of the vertical conveyance device 10. A storage unit 21 for storing angle information about the core Q is provided. Further, the control device 17 is a limit switch for operating the vertical conveying device 10 positioned at the deepest handling side by the forced operation control unit 19 from the retracted position of the grain culm supply guide 12 to the clamping operation position. An automatic return control unit 22 is provided for automatically returning to the original posture of the vertical transport device 10 stored in the storage means 21 based on the detection result at 15.
In addition, in order to perform normal handling depth control, a culm length detection sensor S
1 is provided on a U-shaped frame 23 for supporting the holding rails of the vertical transport device 10, and a grain for detecting the presence or absence of a grain stalk at the base of the vertical transport device 10 and initiating the handling depth adjustment. A culm presence / absence detection sensor S2 is provided. The detection signals of the culm length detection sensor S1 and the grain culm presence / absence detection sensor S2 are also input to the control device 17.

When the normal harvesting work is completed and the threshing process is performed on the grain stalks manually cut on the headland in the field, the self-removable combine is stopped on the headland. The cutting pre-processing device 3 is stopped, and the threshing device 4 is driven. With the worker standing beside the feed start end of the feed chain 11, the grain culm is moved to the feed start end of the feed chain 11. At this time, the grain stalk supply guide 12 in the holding action position is swung up to switch to the retracted position. With the switching of the grain stalk supply guide 12 to the retracted posture, an ON signal of the limit switch 15 is input to the control device 17. As a result, the forced operation control unit 19 of the control device 17 automatically operates the electric motor 18 so that the vertical conveyance device 10 is brought into the deepest state. Accordingly, as shown in FIG. 4, the transport end of the vertical transport device 10 moves away from the transport start end of the feed chain 11, so that the feed chain 1
1, the vicinity of the transport start end is further opened, and it becomes easy to supply the grain stalk to the transport start end of the feed chain 11 manually. When the pillow handling operation by hand is completed and the culm supply guide 12 is manually changed from the retracted position to the clamping operation position in order to shift to the next harvesting operation, the off signal of the limit switch 15 accompanying the change causes The automatic return control unit 22 of the control device 17 performs control for returning the vertical transport device 10 to the original posture stored in the storage unit 21 based on the detection information of the potentiometer 20.

[Another Embodiment] The control of the automatic return by the automatic return control unit is performed by detecting the attitude of the vertical transfer device such as a potentiometer for a predetermined period of time from the handling attitude to shallow handling. The vertical transport device may be operated to return. In the above-described embodiment, the handling depth adjusting device having a structure in which the vertical conveyance device is swung about the horizontal axis on the rear side of the vertical conveyance device as a fulcrum has been described. The present invention may be applied to a handling depth adjusting device having a structure that swings around a laterally oriented axis.
