Description

[Detailed Description of the Invention] The present invention relates to a greening device that excavates the top surface with reeds pulled by a tractor.

The purpose of this is to make it easy to perform ridge work, to be able to return the soil well to the trenches dug with greenery, and to simplify the structure, making it easy to operate manually. The purpose is to provide a writing cultivation device.

The feature of the green plowing device of the present invention is that the dual-purpose hammer B is supported through a coupling mechanism 9 that is arranged at the rear of the towing vehicle A so as to be able to swing in the left and right directions around the vertical axis. The arms 5 are connected, and the axis is directed to the lower end of the support arm 5 in the direction of movement of the aircraft,
In addition, a shaft 10 rotatably configured around its axis is pivotally mounted, and the dual use green B is fixed to the front end side of the shaft 10, so that the dual use 9B is attached to the support arm 5. The lower end of a first rod 17 is provided on the lateral side of the rear end of the shaft 10 with its shaft center facing in the vertical direction on the rear side of the dual-use pear B. One end of a second rod 18, whose axis is directed in the front-rear direction of the fuselage and whose intermediate portion is pivoted to the support arm 5 via a horizontal shaft 21, is connected to the upper end of the first rod 17. In addition to being pivotally connected, a grip operation section 22 is provided at the other end of the second rod 18, and the grip operation section 22 is disposed near the rear of the towing vehicle A. By operating the grip operation section 22 in the vertical direction, the connecting mechanism unit is swung in the left and right directions so that the position of the dual use green B can be changed in the lateral direction of the fuselage. , the tilting posture of the dual-purpose support B can be changed via the second rod 18, the first rod 17, and the longitudinal axis 10 of the fuselage, and this structure provides the following effects. play.

In other words, since the Mayuzumi is connected to the rear of the towing vehicle via a coupling mechanism that is configured to be able to swing left and right around the vertical axis, the Mayuzumi can be easily used as a towing vehicle when working with greenery on the edge of a ridge. On the other hand, by largely displacing the machine to one side, it is possible to carry out good pruning work.

The green can be rotated around the longitudinal axis of the machine to change its tilting position from side to side, so for example, the green can be tilted to the left with respect to the direction of movement of the machine and placed on one end of the field. Carry out the work from the other end to the other end, and turn the aircraft to the left.
When the aircraft is being reversed by 0° and the aircraft is returning, the above-mentioned offender is tilted to the right with respect to the aircraft's direction of travel and the soil raised during the outward movement is cleared into the groove of the outward movement. Can be backfilled.

In other words, if the work is simply carried out by keeping the Souyo pear in a vertical position and pulling it up, the soil that has been pushed up will be piled up on both sides of the trench, so on the return trip, the soil will be piled up on both sides of the trench. The mounded soil becomes a nuisance, and the soil that has been raised during the return trip cannot be put into the groove during the outward trip, making it impossible to perform good greening work.

Since the falcon's lateral position and tilting posture are changed using a single operating lever, the structure is simpler than when using separate operating levers. Since the pear's horizontal position and tilting posture can be changed by operating the lever in the horizontal and vertical directions, for example, although there is only one lever, Furthermore, there is an advantage that there are fewer erroneous operations than when changing the tilted posture only by operating the lever in the left and right directions.
