DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agricultural work machine, for example, a ridge coater for repairing and repairing an old ridge that divides a paddy field, or a trench machine having an auger for forming a drain in a field. Related to the working machine.

[0002]

2. Description of the Related Art Conventionally, this kind of agricultural working machine is generally towed by a tractor.
Even when the wheel of this tractor runs along the old ridge while the levee of the ridge coating machine is placed behind the tractor during the work to repair the old ridge, the ridge will not reach the old ridge. When a ridge coater is connected to a tractor, the ridge coater of the ridge coater is connected so as to protrude outward from wheels of the tractor. The same applies to a case where a drainage ditch is formed on a ridge by an auger of a trench excavator.

[0003] However, during non-operation, the ridge-coated body is displaced so as to protrude outward from the wheels of the tractor. Therefore, the ridge-coated body causes an eccentric load on the tractor side, thereby impairing the weight balance of the tractor. Not only may the stability and operability of the tractor run be impaired,
There are also traffic problems.

Therefore, a movable machine frame provided with a rotatable ridge coating body at one end by a pair of links to a machine frame connected to a tractor is movably connected in the left-right direction with respect to the traveling direction of the machine frame. A universal joint on one end of a power transmission shaft is connected to an input shaft provided on the machine frame, and a universal joint on the other end of the power transmission shaft is connected to an output shaft provided on the movable machine frame. The output from this output shaft makes the ridged body rotatable, and the ridged body is retracted by a pair of links to the working position projecting outward from the wheel of the tractor and the ridged body inwardly from the wheel. There has been proposed a configuration that can be moved to a non-working position.

[0005]

However, in the configuration in which the ridged body is moved to the working position and the non-working position by the pair of links, the universal joints at both ends of the power transmission shaft are moved when the ridged body is moved. Due to bending, there is a limit to the bending angle of these universal joints,
There is a problem that the moving amount of the movable machine frame in the left and right directions cannot be increased by the pair of links.

In order to increase the amount of movement of the furrow in the left-right direction, a configuration is conceivable in which the length of a pair of links is increased. By this, the moving distance of the movable machine frame with a ridge coating body behind the machine frame is long and the ridge coating machine as a whole becomes longer in the front-rear direction, and when connected to the tractor, the weight balance before and after the tractor by this ridge coating machine However, there is a problem that a small tractor cannot tow a traveling ridge coater with good stability.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has been made to enable a large amount of movement of an earthwork body, such as a ridged body, in the left-right direction. It can be easily switched to the work position where work is performed and to the non-work position where soil work is not performed when not working, and this earth work body can be moved to the work position and rotational power can be reliably transmitted to this earth work body. By moving the earth work body to the non-working position, transmission of rotational power to the earth work body can be reliably shut off, and the earth work body moved to the non-work position does not malfunction and the weight balance is lost. It is an object of the present invention to provide an agricultural work machine capable of preventing running and achieving stable running.

Further, by fixing the movable machine frame by the movable machine frame fixing means, the earth working body of the movable machine frame is fixed at a predetermined work position. When the input shaft of the machine frame is rotated, the output shaft of the movable machine frame connected to the input shaft is rotated by the input shaft, and output from the output shaft to the earthwork body and the earthwork is performed. The body is rotated, and a predetermined earthwork is performed on the earthwork body. Next, at the time of non-operation, the fixing of the movable machine frame is released by the movable machine frame fixing means, and the movable machine frame is moved backward to the other end in the left-right direction by a pair of links, so that the movable machine frame is fixed. The earthwork body is retracted to the other side of the machine frame, and the earthwork body is moved to a predetermined non-working position where earthwork is not performed. Also, the soil working member of the movable machine frame power transmission means together with the rear retraction movement is operated in a predetermined non-working position, i.e., connection between the output shaft of the input shaft and the movable machine frame of the machine frame at the clutch It is released. Further, by fixing the movable machine frame by the movable machine frame fixing means, the earth working body of the movable machine frame is fixed at a predetermined non-working position. Then, even if the input shaft of the machine frame is rotated, the output shaft of the movable machine frame is not rotated by the input shaft, and the earth work body is not rotated by a malfunction.

Output to clutch claw of input side engaging body when moved to position
Engage the clutch claws of the side engaging body so that they engage with each other
The output shaft can be securely connected to the input shaft. Also, the earthwork body
When it is moved to the non-working position, it
Separate the force-side engagement body and secure the connection between the input shaft and the output shaft.
Indeed you can cancel. Therefore, the soil moved to the working position
The power transmission to the working body is reliable and moved to the non-working position
Power transmission to the earth work body can be reliably shut off.
