The details of the operation will be described in the section of operation based on the flowchart shown in FIG. Next, the operation will be described. First, when the engine is started and the traveling vehicle body 2 is operated for forward traveling while transmitting the rotating parts of the body by operating a cutting clutch device and a threshing clutch device (not shown), the controller 5 detects the cutting clutch sensor. S ₆ , a work start signal is input from each of the threshing clutch sensor S ₇ , and the vehicle speed sensor S ₈ to start up and start the control operation.

When the combine starts harvesting and threshing in this manner, the culm in the field is replaced with the weeding rod 1 at the lower front end.
8 and then the culm raising device 19
Is raised from the lying state to the upright state by the raising action, the root of the stock reaches the reaper 17 and is cut off, and is squeezed by the action of the scraping wheel 20a and the scraping endless belt 20b to be squeezed. 21 and is conveyed to the rear upper part in a continuous state.

A large number of rows of the cereal culm are collected, conveyed by the left and right front conveying devices 21 and merged at the rear, and successively transferred from the handling depth adjusting device 22 to the supply adjusting device 4 in a continuous state. The feed reaches the starting end of the feed chain 6 and is supplied to the threshing apparatus 1. The grain culm is threshed by the rotating handling drum 9 while the spike is inserted into the handling chamber 7 and passed while the stem is being conveyed while being clamped by the feed chain 6. . Then, the threshing product reaches the lower sorting room and is subjected to the sorting wind and the action of the rocking sorting device to be sorted.

As described above, the combine continuously performs harvesting and threshing work, harvests the threshed and sorted kernels, and collects and stores them in a Glen tank. Now, as described above, when the cutting and threshing operation is continuously performed, the pre-cutting device 3
Is held at the height of the lower part of the normal working position a, the position is from the position detection sensor S ₂ control - are input to the La 5. The transported grain culm is detected and input from the front grain culm sensor S ₃ − and the rear grain culm sensor S ₃ −, respectively. Further, culm length detection sensor S ₁ is entered by detecting the grain稈丈.

Then, the handling depth adjusting device 22 transmits the detection information from the head sensor S ₄ and the stock sensor S ₅ to the controller 5.
, And based on the operation signal outputted from the controller 5, the handling depth control motor M ₂ is controlled and operated, and the handling depth is automatically adjusted via the connecting rod 23. . In this case, controller - La 5 determines that the most suitable threshing depth positions positions passing between the tip position pike sensor S ₄ and strain based sensors S ₅ of the transport culms,扱深in that position Adjustment control is performed so that the adjustment position of the adjustment device 22 is adjusted.

Next, when the traveling vehicle body 2 reaches the edge of the field and cuts the headland, the cutting body is moved up and down so that the tip of the weeding rod 18 does not collide with the ridge protruding at the edge of the field. As shown in FIG. 12, the cylinder-37 is extended to move the pre-cutting device 3 to the high cutting operation of the grain culm while ascending. Hereinafter, the high mowing control will be described with reference to the flowchart of FIG.

First, in a state where the cutting clutch sensor S ₆ , the threshing clutch sensor S ₇ and the vehicle speed sensor S ₈ are each ON (during operation), the cutting pre-processing device 3 is raised and the high cutting position c (see FIG. 12). Then move to harvesting the headlands. At this time,
Controller - La 5, the position detection sensor S _2, the front culms sensor S ₃ - detection information culms and location of the pre-processing unit 3 (high cutting position c) is fed cutting from is input.

[0029] Then, controller - La 5 inputs the detection information by detecting the culms of culm length detection sensor S ₁ is been fed, threshing depth determines that longer grain稈丈than the reference value (60cm) When only non-detection information is input, control is performed only by the adjustment device 22, and control is performed by both the handling depth adjustment device 22 and the supply adjustment device 4 at the same time, judging that the grain stalk length is shorter than the reference value (60 cm).

[0030] First, controller - La 5, the detection information is input from the culm length detection sensor S _1, in the embodiment,
Output 1, 5 / sec threshing depth control mode - controls the motor -M ₂ to deep threshing side to work by adjusting the threshing depth adjusting device 22 to about 15cm deep threshing side. Complete cutting high by the control operation described above, the rear culms sensor S ₃ - is completed by detecting that there are no more culms. Thereafter, the handling depth adjusting device 22
In this case, the off-delay operates and returns to the shallow side by about 12 cm with a predetermined time delay, and returns.

Next, grain稈丈is extremely short, top a non-detection information control in a state where not reach the culm length detection sensor S ₁ - If you type in La 5, controller - La 5, threshing depth adjusting device 22 a delivery regulation apparatus 4 and most deep threshing each threshing depth control signal for adjusting the position of the motor - motor -M ₂ and supply control mode -
Controlling output to motor -M _1. Accordingly, the handling depth adjusting device 22 and the supply adjusting device 4 are controlled to the deepest handling positions and supply the extremely short grain culm to the threshing device 1.

In this case, the supply control device 4 is controlled and controlled.
Inherits an extremely short cereal stem that is largely adjusted to the deep handling side from the end of the handling depth adjusting device 22, and further adjusts to the deep handling side to supply to the auxiliary feed chain 8. However, at this time, short cereal stems whose roots do not reach the clamping position of the feed chain 6 are transported by the auxiliary feed chain 8,
All culms are directly supplied to the handling room 7 from the supply side.

At this time, the cereal stalk is composed of the auxiliary feed
From the end portion of the toothed tooth 13 to reach the rotation range of the toothing 13, the toothed tooth 13 is quickly scraped off and carried around, so that threshing can be reliably performed. When one step of the cutting and threshing operation is completed as described above, the controller 5 determines that the processing is completed by detecting that the rear culm sensor S _3- has run out of cereal culm, and determines that the corn culm is terminated. Originally, the handling depth adjusting device 22 and the supply adjusting device 4 are returned to the shallow handling position. In this case, the handling depth adjusting device 22 basically returns to the handling position before the adjustment, but the re-starting is returned to the deep side so that it can be started from the slightly deep handling position. On the other hand, the supply adjusting device 4 returns to the normal standby position.

The return timing and the return position of the handling depth adjusting device 22 and the supply adjusting device 4 when returning to the original state after the control operation are set in advance and input to the controller 5 as reference information. And It should be noted that the numerical values described in the description of the above-described embodiments show one embodiment, and do not limit the scope of rights.
