Description

[Detailed description of the invention] (Industrial field of application) The present invention relates to a handling depth detection device for a combine harvester.

(Prior art) A conventional combine harvester is as shown in Fig. 1, in which the grain culms that have been divided by a weed cutting unit 1 are raked by a raking device, raised by a pulling device 2, and harvested by a reaping device. The grain culm is transported rearward in an upright position by a transport device, and then taken over by the ear tip transport belt and stock side transport belt 3, so that the grain culm lies on its side and is fed into the feed chain 5 of the threshing machine 4. When transported by the plant side conveyance belt 3, the length of the culm can be adjusted by changing the angle of inclination of the belt. A sensor detects the grain culm and adjusts accordingly. In addition, in FIG. 1, 6 indicates a driver's cab, and 7 indicates a crawler.

(Problems to be solved by the invention) With the sensor installed at the entrance of the handling barrel as described above, the sensor may not operate depending on the amount of grain culm, the attitude of the grain culm being sent, etc.

(Means for solving the problem) Therefore, the technical problem of this proposal is to provide a handling depth detection device for combine harvesters in which the sensor operates reliably. The technical means is that the deep handling detection device is a rubber cover that is hung down toward the supply plate at the inlet of the handling cylinder, two slits are attached to this to form a suspended piece between them, and this suspended piece is used to detect handling. This is a depth detection device for a combine harvester, which is equipped with a magnet that operates a depth detection switch.

(Example) Hereinafter, a description will be given based on the embodiments shown in the drawings.

In the case of a combine harvester as shown in FIG. 1, a rubber cover 9 is normally provided vertically toward the supply plate 8 at the entrance of the handling barrel chamber.

The present invention uses the above-described rubber cover to detect excessive handling.

That is, in response to the detection switch 12 provided in the deep handling detection device of the supply plate 8, the rubber cover 9
Two slits 10, 10 are provided in the slit, a hanging piece is formed between them, and a magnet 13 for actuating the detection switch is provided on this piece. As the detection switch, an external reed switch of an NC type proximity switch or the like is used.

In the present invention, as described above, the two slits 10, 10 are attached to the rubber cover 9 to form the suspension piece 11, so when the grain culm touches this, the suspension piece 11 moves easily, and thereby the magnet 13 also moves. Since it moves, the detection switch 12 is activated to notify that it has been handled too hard.

(Effect of the invention) According to the present invention, since the suspension piece 11 is easy to move, it is possible not only to improve the detection accuracy, but also to improve the detection accuracy.
The detection device is characterized by being small and lightweight, and can be easily installed.
