The set lamp provided in 9 displays the monitor 27, but if the set lamp lights here, the set position of the position control lever 19 is not appropriate, and therefore the position control lever 19 is operated. Gently position it so that the set lamp goes out. In this way, position control is performed in the state in which the position is set to the set position.
Is operated up and down to set it to a desired position, this set position and the detection result from the lift arm angle sensor 22 provided on the hydraulic lift arm 21 are input to the control unit 11 constituted by a microcomputer or the like. If the two do not match, the control valve (not shown) is controlled to control the hydraulic lift arm 2
The position of the working unit 2 is adjusted by swinging 1 up and down so that the working unit 2 is positioned at the set position, and the automatic control of the working unit position is performed in this manner. If it is desired to manually move the working unit up and down, the control panel 29
The position control is released by switching the lift arm manual switch 23 provided in the above to the manual side, and the vertical up and down movement can be performed manually. Furthermore, if the automatic working depth control is desired to be activated during the operation of the position control, the position control lever 19 is operated to the lowered position and the automatic working depth switch 18 is pressed (displayed on the monitor and the position control is released). The plowing depth set value set by the plowing depth setting device 16 is compared with the detection value from the plowing depth sensor 25 that detects the plowing depth by detecting the swinging posture of the rear cover 24 of the working unit 2. It is determined that the control valve is switched by the control command of the control unit 11 so that these values match, and the lift arm 21 moves up and down, whereby the automatic plowing depth control is performed. Further, when it is desired to perform automatic tilt control such as when cultivating slopes, the automatic tilt switch 17 is pressed (displayed on the monitor), and the tilt changeover switch 14 and the tilt setting device 15 are provided.
When a desired tilted state is set by operating, the set value and the detection value by the tilt detection sensor (not shown) are compared and determined, and the control unit 11 controls so that the values match. The tilt is automatically controlled, and the posture of the working unit 2 is controlled in this manner. Incidentally, 26 is a grip (handrail) provided on the fender 4, and 28 is a main transmission lever.

In the embodiment of the present invention constructed as described above, as described above, the control such as the position control, the automatic plowing depth control, the automatic tilt control and the like is arbitrarily performed by switching the switches. The control section 11 for controlling them is the step groove-shaped concave groove section 1 formed in the fender 4.
No. 0 is used as a storage part, and it is mounted inside the position sensor 20 and covered by the cover body 13. Therefore, the control part 11 is provided with the concave groove part 10 of the fender 4 and the cover body 13. Will be reliably protected by the surroundings, and this protective structure
The rear wheel 8 covered by the fender 4 has a complete sealing structure with the fender 4 interposed therebetween.

As a result, the control section 11 is provided on the fender 4 together with the position sensor necessary for the attitude control based on the microcomputer of the working section, which can greatly contribute to the compactness of the machine body.
There is no need to protect the control unit 11 from mud or the like by using a storage case to form a completely sealed structure, unlike the conventional one in which a control unit is provided on the traveling wheel side portion of the fender 4.
Since the control unit 11 can be protected by effectively using the fender 4 itself, the fender 4 itself is protected by the control unit 1.
1 can be effectively used as a protection member. Furthermore, since the groove portion 10 is formed integrally with the fender 4, it is easy to manufacture and the cost is low.

Further, since the control section 11 is arranged on the upper surface of the groove bottom of the concave groove section 10 of the fender 4, and the concave groove section 10 is open on the driver's side, the lead wire pulled out from the control section 11 cannot be forced. Since it is possible to pull the lead wires toward the inside of the fuselage as it is, there is no need to consider opening the openings in the fender 4 and pulling the lead wires toward the inside of the fuselage, and as a result, it is necessary to seal these openings. Will be completely eliminated, and simplification of the assemblability as well as the structure will be achieved.

Moreover, the cover body 13 has automatic plowing depth control,
Since switches such as automatic tilt control are centrally provided, the operator can operate the switches while checking the rearward work, and these switches should be arranged near the grip 26. Therefore, it is possible to effectively protect the operator's hand from accidentally coming into contact with the switches, which is excellent in operability. In addition, since the switches are integrally provided as a kit on the cover body 13, it is not convenient for assembly and parts management, and is easy to maintain.

[0013]

In summary, since the present invention is constructed as described above, a control unit for controlling the posture of the working unit is
By providing the fender with the position sensor of the position control lever necessary for automatic control, it can greatly contribute to the compactness of the aircraft, but the control part stores the concave groove part formed in the fender itself for the control part. The position sensor is housed together with the control unit in this control unit housing unit. Therefore, the control unit has a sealing structure that is completely isolated from the running wheel side by the recessed groove formed on the fender, and the fender itself includes the position sensor to protect the control unit from dirt and the like. Will be done. For this reason, like the conventional one in which a control unit is provided on the running wheel side of the fender, the control unit and the positive position sensor housed together with the control unit are made into a completely sealed structure using a storage case, and the mud Since it is not necessary to protect the control parts, etc., it is possible to effectively use the fender itself to protect these control parts, etc., and the fender itself is effective as a protective member of the control part together with the position sensor necessary for automatic control Available.

Moreover, the control unit is arranged on the upper surface side of the groove of the fender together with the position sensor,
Moreover, since this groove is open on the driver's side, the lead wires drawn from the control unit and the position sensor can be easily pulled together from the groove into the fuselage within a short distance. There is no need to consider opening the fender and pulling the lead wire toward the inside of the fuselage, unlike the case where the control part is arranged on the running wheel side part of the fender, and as a result, these openings are sealed. There is no need to stop it at all, which simplifies the assembling work together with the structure.

If it is desired to manually move the working unit up and down, the control panel 29
The position control is released by switching the lift arm manual switch 23 provided in the above to the manual side, and the vertical up and down movement can be performed manually. Furthermore, if the automatic working depth control is desired to be activated during the operation of the position control, the position control lever 19 is operated to the lowered position and the automatic working depth switch 18 is pressed (displayed on the monitor and the position control is released). The plowing depth set value set by the plowing depth setting device 16 is compared with the detection value from the plowing depth sensor 25 that detects the plowing depth by detecting the swinging posture of the rear cover 24 of the working unit 2. It is determined that the control valve is switched by the control command of the control unit 11 so that these values match, and the lift arm 21 moves up and down, whereby the automatic plowing depth control is performed. Further, when it is desired to perform automatic tilt control such as when cultivating slopes, the automatic tilt switch 17 is pressed (displayed on the monitor), and the tilt changeover switch 14 and the tilt setting device 15 are provided.
When a desired tilted state is set by operating, the set value and the detection value by the tilt detection sensor (not shown) are compared and determined, and the control unit 11 controls so that the values match. The tilt is automatically controlled, and the posture of the working unit 2 is controlled in this manner. Incidentally, 26 is a grip (handrail) provided on the fender 4, and 28 is a main transmission lever.

In the embodiment of the present invention constructed as described above, as described above, the control such as the position control, the automatic plowing depth control, the automatic tilt control and the like is arbitrarily performed by switching the switches. The control section 11 for controlling them is the step groove-shaped concave groove section 1 formed in the fender 4.
0 is the storage groove, where the position sensor 20
Since it is mounted in a structure in which the cover body 13 and the cover body 13 cover the interior,
1 is surrounded and protected by the storage groove portion 10 of the fender 4 and the cover body 13. Moreover, this protection structure is a sealing structure in which the fender 4 is interposed between the rear wheel 8 covered by the fender 4. Become.

As a result, the control section 11 is provided on the fender 4 together with the position sensor necessary for the attitude control based on the microcomputer of the working section, which can greatly contribute to the compactness of the machine body.
There is no need to protect the control unit 11 from mud or the like by using a storage case to form a completely sealed structure, unlike the conventional one in which a control unit is provided on the traveling wheel side portion of the fender 4.
Since the control unit 11 can be protected by effectively using the fender 4 itself, the fender 4 itself is protected by the control unit 1.
1 can be effectively used as a protection member. Further, since the storage groove portion 10 is formed integrally with the fender 4, it is easy to manufacture and the cost is low.

In addition, the control unit 11 is disposed on the groove bottom surface of the storage groove portion 10 of the fender 4, and the groove portion 1 is provided.
Since 0 is open on the driver's side, the lead wire drawn out from the control unit 11 can be naturally drawn into the inside of the fuselage as it is, and the opening is opened in the fender 4 to lead the lead wire to the inside of the fuselage. There is no need to take care of pulling in the openings, and as a result, there is no need to seal these openings, which simplifies the assembling work together with the structure.
Further, in the cover body 13 that covers the storage groove portion 10, the upper surface plate 13c on which the switches are provided is higher than the fender upper surface 4a, so that the cover body 13 can be easily distinguished from the fender upper surface 4a and the operability is not impaired. Moreover, the driver's seat side of the storage groove portion 10 is covered by the side plate 13b at a position closer to the driver's seat than the storage groove portion 10 and extended to a position lower than the bottom surface 10a of the storage groove portion 10, For this reason, the control unit 11 is covered in a state where the driver's seat 6 side is substantially lower than the bottom surface 10a of the storage groove portion 10, and can contribute to the prevention of infiltration of muddy water or the like from that side.

Moreover, the cover body 13 has automatic plowing depth control,
Since switches such as automatic tilt control are centrally provided, the operator can operate the switches while checking the rearward work, and these switches should be arranged near the grip 26. Therefore, it is possible to effectively protect the operator's hand from accidentally coming into contact with the switches, which results in excellent operability. In addition, since the switches are integrally provided as a kit on the cover body 13, it is not convenient for assembly and parts management, and is easy to maintain. In addition, the storage recessed groove portion 10 is a step surface between the front groove bottom surface 10b and the rear groove bottom surface 10b which have a step on the front side and a high step on the rear side.
Since the control unit 11 is provided on the front side b, it is possible to prevent the intrusion of muddy water from the front side, and the lower front bottom surface 10b and the cover body 1
It is possible to secure a space for the potentiometer 20 by widening a space between the front side portion 3 and the front side portion which is inclined in a front low rear height. As a result, the front side portion of the cover body 13 can be made to follow the curve of the fender 4.

[0013]

In summary, since the present invention is configured as described above, the control section for controlling the attitude of the working section can be provided on the fender so that the control section can contribute to downsizing of the machine body. The concave groove portion formed in itself is stored as a storage portion. Therefore, unlike the conventional one in which a control unit is provided on the running wheel side portion of the fender, it is not necessary to protect the control unit from dirt and the like by using a storage case to form a completely sealed structure. The control unit can be effectively used to protect the control unit, and the fender itself is effectively used as a protection member for the control unit.

Moreover, since the accommodation groove for accommodating the control section is open on the driver's side, the lead wire drawn out from the control section can be drawn into the body as it is within a short distance without difficulty. As a result, unlike the case where the control unit is arranged at the running wheel side portion of the fender, it is not necessary to open the fender and draw the lead wire into the inside of the fuselage. As a result, these openings are sealed. It is not necessary and simplifies the assembling work together with the structure.

In addition, the cover body that covers the storage groove is
Since the upper surface plate on which the switches are provided is higher than the upper surface of the fender, it can be easily distinguished from the upper surface of the fender and the operability is not impaired. Moreover, the driver's seat side of the storage groove is covered by the side plate in a position closer to the driver's side than the storage groove and extended to a position lower than the bottom surface of the storage groove. The driver's seat side is covered in a state of being substantially lower than the bottom surface of the storage groove portion, which can contribute to the prevention of intrusion of muddy water or the like from the side.
