In the reaping and harvesting work performed in this way, when the tree head cutting device @1 of the pre-processing device 13 is in the proper position, the backs of the two long and short contact hinges 59, 61 of the tree head tip sensing sensor 5, - 7) is in a state where the contact sensor 59 is separated from the crown tip and the other contact sensor 61 is in contact with the crown tip, and the control device 7 is in an inactive state. That is, as shown in FIG. 5, the solenoid valve 73 of the relief circuit is located at the 8th position, and the solenoid valves 77 and 79 of the operating circuit are located at the C position and E position, respectively.
The hydraulic oil is returned to the hydraulic oil tank 87 via a relief circuit. Therefore, the lowering device 3 is stopped and the canopy head cutting device 1 is held at the proper position.

Now, the tree head cutting device 1 is lowered from the proper position, and the two long and short sensors 59.
When both of the solenoid 61 come into contact with the crown tip, the solenoid 75
is actuated and the solenoid valve 73 is switched to the B device, and the solenoid 81 is actuated and the solenoid valve 77 is switched to the D (i7 position), and the hydraulic oil acts on the vertical movement device 3 to switch the top head cutting device. 1. Then, the tree head cutting device 1 is raised.
is in the proper position, one contact sensor 59 is separated from the tip of the tree head, and the other contact sensor 61 is in contact with the tip of the tree head, then the control device 7 becomes inactive. After switching, the vertical movement device 3 comes to a stop.

In addition, the tree head cutting device 1 may become soiled from its proper position.
Two long and short contact lensers 59 of the tree tip detection sensor 5
．． 61 are separated from the tip of the crown, the solenoid 83 is activated and the solenoid valve 79 is switched to the F position.
The hydraulic oil of the lowering device 3 is returned to the hydraulic oil tank 87 to lower the tree head cutting device 1. When the tree head cutting device 1 is in the proper position and one contact sensor 59 is separated from the tree head tip and the other contact sensor 61 is in contact with the tree head tip, the control device 7 is activated. The vertical movement device 3 is switched to a non-acting state and stops.

The sensor 5 for detecting the tip of the tree top is not limited to the above-described embodiment; for example, a phototube may be provided to irradiate the tip of the tree top and lie down so as to cover the sensor.

The present invention is a canopy harvesting machine equipped with a canopy head cutting device for cutting off the canopy head of planted sweet potato, and a vertical movement device that moves the canopy head cutting device up and down, and which cuts the canopy head tips of 11 canopies. A tree head tip sensing sensor is installed to detect the tree head tip, and a control 1AM is installed to control the vertical movement of the lowering device based on the signal from the tree head tip sensing sensor. Since the i51@ is configured such that the height of the canopy standing in the tub is maintained at the top cutting position, the top can always be cut off in an appropriate position. Therefore, since excess canopy heads are not fed into the processing section, the horsepower consumption of the processing section is reduced, and there is less chance that cut canopy heads will be mixed in with cut raw material cane stalks. The wind selection effect is improved, and the raw material cane stalks that are neatly sorted can be harvested. Furthermore, when cutting off the head of the shoot, it is less likely that the raw material cane stem will be cut off at the same time, making it possible to eliminate waste.

It should be noted that this invention is not limited to the above-mentioned embodiments, and the invention can be implemented in modes other than the above-mentioned embodiments.

Further, in the claims, reference numerals are used for convenient comparison with the drawings, but the reference numerals do not limit the technical scope of the present invention.
