Abstract

PURPOSE:To prevent deep plowing in starting tillage by decreasing the set plowing depth in starting the tillage in plowing depth control. CONSTITUTION:Plowing depth control is carried out from a higher position of a tiller in starting tillage by a CPU 15 based on detection with a plowing depth sensor 2 using a shallower plowing depth than a given plowing depth set by a position setter 27 as the target by hydraulic operation. When the plowing depth attains a shallow value, plowing depth control is performed by the given plowing depth. When a car body is advanced, control for keeping the given plowing depth is carried out. As a result, since the position of expanded and softened after the tiller can be detected in starting the forward tillage, a greater plowing depth than that required is not provided.

Functions and Effects of the Invention When starting tillage, set a predetermined tillage depth and use the tillage device (1).
When the hydraulic pressure is operated from a high position to target the predetermined plowing depth position and the control start program (4) corrects the plowing depth to a shallower plowing depth (b) than the set predetermined plowing depth (a). The tilling device (1) is lowered aiming at a shallow tilling depth (b). The plowing depth sensor (2) detects the position of the uncultivated soil surface behind the tiller (1), and when it detects this shallow plowing depth (b), it descends from above and reaches this shallow plowing depth. Following a series of descending movements, plowing depth control using the predetermined plowing depth (a) is started, and when the vehicle body (3) advances, the predetermined plowing depth (a) is reached, and then this predetermined plowing depth (a) is Vehicle body to maintain (3
) to the specified tilling depth (A) by raising and lowering the tilling device (1).
It is possible to control tillage to maintain a constant value. The shallow plowing depth (b) is too shallow and the specified plowing depth (
It is best to set the plowing depth to an appropriate shallow plowing depth that does not take much time to reach b), and the plowing depth sensor (2) detects the shallow plowing depth (b) when it detects that the shallow plowing depth (b) has been exceeded. It is good to do as you please.

In this way, when a shallow plowing depth (B) is detected before reaching the predetermined plowing depth (A), forward plowing with plowing depth control based on the predetermined plowing depth (A) is started, so that the predetermined plowing depth (A) is reached. When the plowing depth sensor (2) reaches the predetermined plowing depth (a) by detecting the position of the expanded and soft plowed soil behind the tilling bag N (1), the plowing depth sensor (2) can detect the predetermined plowing depth (a), so the plowing depth can be set to be deeper than necessary. This is a good thing because it eliminates the drawbacks of the conventional technology.

A work mode selection switch (30) for starting tillage depth control by lowering the tilling device (1) from a traveling or turning position where the lifting arm (23) has been raised to a position close to the upper limit of the lift.
to "start tilling depth", set the desired tilling depth (A) with the tilling depth setting device (23), and turn the setting lever (2) of the position setting device (27).
8) is set to the predetermined plowing depth (a) position, the control start program (4) causes the CPU (+5) to read each sensor value and setting value in step (38), but at this position, the plowing depth is not set. Sensor (2) cannot detect plowing depth. Is the lifting arm of step (39) in the raised position? The judgment is YES.
S, the specified plowing depth shallowest flag is set in the next step (40), that is, the flag that determines the shallow plowing depth (b) relative to the predetermined plowing depth (a), and the raising operation is performed in the next step (41). ? is NO, so is the specified plowing depth shallowest flag set in step (42)? The judgment is made in step (40
), so the answer is YES and step (43) is set.
) to change the designated plowing depth to the shallowest.Next, the elevating arm operation can be determined based on the specified plowing depth in step (40) and the detected plowing depth.Since the plowing depth sensor (2) cannot detect this,
The setting value of the position setting device (27) is used to determine the lowering, and the judgment of the lifting arm operation in step (45) is set as "lowering", and the proportional solenoid valve for lowering in step (47) is activated.
32), the lifting arm (23) rotates downward and the tilling device (1) descends, but at this time the rotary shaft (6) is rotating. When the tillage device (1) that has descended to the soil surface detects a shallow tillage depth (b),
The tractor body (3) moves forward, and in step (38) the plowing depth of the plowing depth sensor (2) is read.
9) is No, so the process moves to step (41), and the next step (42) is No, so the process moves to step (44), and the lift arm operation is determined based on the predetermined plowing depth (a) and the detected plowing depth. Since the plowing depth (A) has not been reached, the lowering solenoid excitation Fi& (step 47) is continued. When the predetermined plowing depth (A) is passed, step (39) is No, step (42) is also No, and step (44) is the predetermined plowing depth (A) and plowing by the plowing depth setting device (29). Since the operation can be determined by the plowing depth detected by the depth sensor (2),
If it is determined to rise in step (45), step (4)
In step 9), the designated plowing depth shallowest flag is set, and the raising proportional solenoid is excited (step 50) to raise the plowing depth.Thereafter, in order to maintain the predetermined plowing depth (a), the designated plowing depth is raised, lowered, and lowered in step (45).
A constant plowing depth (a) is maintained by controlling either neutral or neutral.
