なつている。 That is, FIG. 1 is a schematic plan view mainly showing the part of such a combine harvester that performs reaping or threshing, and in which the weeding bodies 2a to 2e supported by rod-shaped weeding rods 1a to 1e protrude forward and are fixed. As the combine moves forward, the grass branches 2a~
Grain culms pushed apart by 2e are divided into cutting rods 1a to 1e.
The grains are cut by a clipper-like reaping section 3 installed just below the combine, and then transported above the combine by a chain-like grain conveyor 4 to a separately installed section. After being supplied to the grain conveying chain 5, the grain is inserted into a threshing section 6 by its rotational movement, and the ears are threshed by a rotating handling cylinder 7 similar to a general threshing machine.
なお、脱穀の際、扱ぎ胴７に対する穂の相対関

うえ、穀稈搬送チエーン５に対する穀稈の供給状
況を調節している。 In addition, when threshing, if the relative relationship of the ears to the handling barrel 7 is too deep or too shallow, complete threshing will not be achieved. An ear tip sensor SFS and a ear tip sensor SFD are provided to detect the tip and root of the ear, control the supply adjustment section 8 according to the detection status, and adjust the supply status of grain culm to the grain culm conveyance chain 5. There is.

た回転輪である。 In addition, in order to detect the presence or absence of grain culm supply to the threshing section 6, a grain culm sensor SFF is provided on the same line as the ear tip sensor SFS and the ear tip sensor SFD, and also detects the harvested grain culm between the cutting rods 1a to 1c. Grain culm conveying device 4
An auxiliary grain culm conveying device 9 similar to the same device 4 is provided for the purpose of transferring the grains to the grains. Incidentally, reference numerals 10 and 11 are rotary wheels provided with protrusions for raking grain culms toward the respective grain culm conveying devices 4 and 9.

として、扱ぎ深さの自動制御が行なわれる。 Therefore, when the grain culm sensor SFF generates a detection force, a separately provided control unit is activated, and if neither the ear head sensor SFD nor the ear tip sensor SFS generates a detection output, the supply adjustment unit 8 is activated to adjust the hydraulic pressure. The mechanism controls the degree of insertion of the ear into the threshing section 6, and when the ear tip sensor SFS generates a detected force, the feed adjustment section 8 is similarly controlled to shallow the degree of insertion of the ear into the threshing section 6. ,
Automatic control of the handling depth is performed to maintain the position of the panicle at the appropriate insertion depth at all times.

However, in the conventional control unit, the head sensor
The handling depth is controlled in immediate response to the detection force of the SFD and the tip sensor SFS, and the cutting depth is controlled.
Alternatively, if weed fragments, etc. are mixed in and remain in the tip sensor area, causing a detection force, the shallow handling control will continue and proper handling depth control will not be possible. This created problems that made it unsustainable.
前述の問題を解決するため、本発明はつぎの手

In order to solve the above-mentioned problem, the present invention is constructed by the following means.
すなわち、上述のコンバインにおいて、脱穀部

を停止させるゲート回路とを設けたものである。 That is, in the above-mentioned combine harvester, the detection force of the ear sensor provided near the entrance of the threshing section to detect the root of the ear, and the ear tip sensor provided in the threshing section to detect the tip of the ear is generated. Additionally, a gate circuit is provided which stops the handling depth control when the detection force of the ear head sensor disappears.

Therefore, even if broken ears, weed fragments, etc. remain in the area of the ear sensor, shallow handling control is performed, and if the detection force of the ear sensor disappears, the gate circuit will control the handling. Automatic stopping of depth control takes place.
以下、実施例を示す第２図の回路図以降により
本発明の詳細を説明する。
The details of the present invention will be explained below with reference to the circuit diagram of FIG. 2 showing an embodiment.
穀稈センサSFF、穂先センサSFSは非検出状態
においてオフとなつており、抵抗器Ｒを介して電
源Ｖが抵抗器R1およびR2との接続点へ印加さ
れ、これらの出力は“Ｈ”（高レベル）となつて
いるが、穂元センサSFDは非検出状態でオンと
なつており、抵抗器ＲとR3との接続点がアース
され、その出力は“Ｌ”（低レベル）となつてい
る。 The grain culm sensor SFF and the ear tip sensor SFS are off in the non-detection state, and the power supply V is applied to the connection point with the resistors R1 and R2 via the resistor R, and their outputs are “H”. (high level), but the head sensor SFD is on in a non-detecting state, the connection point between resistors R and R3 is grounded, and its output is “L” (low level). It's summery.

制限用の抵抗器R5を介してトランジスタQ2へ順
方向バイアスを与え、深扱ぎ制御出力FDを生じ
させる。 Therefore, in the non-detection state of the grain culm sensor SFF, the input inversion type NAND gates G 1 and G 2 are in the OFF state, but when the grain culm sensor SFF detects the grain culm, its output becomes “L”. Therefore, NAND gates G 1 and G 2 enter a standby state in which they turn on when any other input becomes “L”, and the earpiece sensor
If the SFD is in the non-detect state, the NAND gate G 2 passes the pulse output of the pulse generator PG and forward biases the transistor Q 2 through the current limiting resistor R 5 to perform deep handling control. Produces an output FD.

る。 In addition, the ear is equipped with a head sensor SFD and a head tip sensor.
When SFS is contacted, NAND gate G 2 is turned off, but NAND gate G 1 is turned on, and in turn, the pulse output from pulse generator PG is given to transistor Q 1 , causing shallow handling control output FS. arise.

る。 Each of the control outputs FS and FD is inserted into the return path of each solenoid valve, and these solenoid valves supply pressure oil to the hydraulic mechanism, and control the supply adjustment section 8 relative to the grain culm conveying device 4. The vertical inclination is controlled by a hydraulic mechanism, and the supply adjustment unit 8 is controlled from the grain culm conveying device 4
The grain culm holding position when the grain culm is supplied to the grain culm and the grain culm holding position when the grain culm is supplied from the supply adjustment unit 8 to the grain culm conveying device 4 again are changed, and thereby the grain culm conveying chain 5 The gripping position of the grain culm is determined and the handling depth is controlled.
また、前述の扱ぎ深さ制御は、制御動作上のオ
ーバシユートを防止するため、ステツプ状制御と
なつており、この目的上、パルス発生器PGが用
いられている。 Further, the above-mentioned processing depth control is a step-like control in order to prevent an overshoot in the control operation, and a pulse generator PG is used for this purpose.

EXORゲートG3の出力は“Ｌ”へ転じ、これによ
つてパルス発生器PGがパルスの発生を停止する
ことにより、扱ぎ深さの自動制御も停止し、不要
な制御が阻止される。 On the other hand, in FIG. 2, an exclusive OR (hereinafter EXOR) gate G3 is provided as a gate circuit, and its output is always "H", so
The enable terminal E of the pulse generator PG is activated and pulses are generated, but the tip sensor
When the detection force of SFS is generated and the detection force of head sensor SFD disappears, and both sensors are turned on, these outputs are simultaneously generated as "L",
The output of the EXOR gate G3 changes to "L", thereby causing the pulse generator PG to stop generating pulses, thereby also stopping the automatic control of the treatment depth and preventing unnecessary control.

行なわれるものとなり、これらの反復により適正
な扱ぎ深さが維持される。 FIG. 3 is a schematic diagram showing the above control situation. As shown in A, when the tip 32 of the grain culm 31 is inserted in the deep handling direction D, a detection force is generated by the tip sensor SFS, and this causes The shallow handling direction S is controlled, and as shown in B, the tip 32 is detected by the tip sensor SFD, and the detection force of the tip sensor SFS disappears, and accordingly, the deep handling direction D is controlled. These repetitions maintain proper treatment depth.
また、Ｃのとおり挿入不足の場合には、穂元セ
ンサSFDがオンとなつているため、穀稈センサ
SFFの検出々力が生ずれば深扱ぎ方向Ｄの制御
がなされ、前述の状態が維持される。 In addition, if the insertion is insufficient as shown in C, the grain culm sensor SFD is on, so the grain culm sensor
When the SFF detection force is generated, the deep handling direction D is controlled and the above-mentioned state is maintained.
以上に対し、Ｄのとおり穂切れ３２が穂先セン

扱ぎ方向Ｓの制御が連続的になされ、穂元センサ
SFDの検出々力が消滅するため、上述のとおり
扱ぎ深さ制御の停止が行なわれ、これにより脱穀
部内の異常発生報告等を行なうことができる。 In contrast to the above, if the broken ear 32 remains in the area of the ear tip sensor SFS as shown in D, the shallow handling direction S is continuously controlled by detecting this, and the ear tip sensor
Since the detection power of the SFD disappears, handling depth control is stopped as described above, and this makes it possible to report abnormalities in the threshing section.
したがつて、穂切れ、雑草の断片等が穂先セン
サの部位へ残留しても、これにより異常な制御を
生ずることが完全に阻止される。 Therefore, even if cut ears, weed fragments, etc. remain at the tip sensor, abnormal control is completely prevented.

The same is true even when realized, and various modifications are possible.

As is clear from the above explanation, according to the present invention, abnormal handling depth control is prevented and control is performed only by the detection operation based on the normal tip of the tip sensor and the tip sensor. The handling depth can be controlled effectively, and a great effect can be obtained in various types of combine harvesters.
