[0003]
[Problems to be solved by the invention]
Since the hulling work is a work for repairing the old hail on the field, the lower end of the hulling body of the hulling machine is aligned with the old hail skirt at the beginning of the work. For this reason, the tractor is operated and the work position is adjusted in a state where the lower end of the hull body of the hull coater is as close as possible to the old hail skirt. At the end of the work, the tractor must turn sharply and change direction from the work position at the corner of the field. For this reason, it is an operation | work which is easy to make a wrinkle coater contact a wrinkle. At this time, if the side cover is lowered more than necessary, the side cover is also likely to come into contact with the bag.
[0004]
Further, since the side cover of the scissor coater described in the above publication follows the old scissors so as to be movable up and down in order to prevent the scattering of the cutting soil, the operating position changes depending on the height of the scissors. In fields with low dredging, the side cover needs to be lowered to a low working position to follow low dredging, but in fields with high dredging, it is not necessary to go down to a low working position because the side cover follows high dredging. As shown in the figure, when it was lowered to the restricted position by link motion, it fell too much.
[0005]
And, if the side cover is too lowered, when aligning at the beginning of the paint coating operation, the bottom of the paint coater of the coater is moved as close as possible to the old kite skirt by the suspension mechanism of the tractor. It is easy to make contact with the old paddle, and even when changing the direction at the end of work, even if the padding machine is lifted by the suspension mechanism of the tractor, the padding machine is tilted forward due to the nature of the suspension mechanism, and the side cover that has been lowered too much There was a risk of damage to the side cover due to insufficient lifting and easy contact with the heel.
[0006]
In addition, in the case of an incline work as shown in FIG. 6 in which the extension roller is removed from the upper surface repairing part of the overcoat body of the overcoat machine, the slope on the incline is provided when the side cover is in the normal operation position. It was necessary to remove with a tool because it touched and damaged.
[0007]
Accordingly, an object of the present invention is to prevent the side cover of the coater from dropping more than necessary and to fix the side cover so as not to interfere with the work.
[0008]
[Means for Solving the Problems]
According to a first aspect of the present invention, there is provided a coater main body of a coater to be pulled by being connected to a suspension mechanism of a tractor, a mission device provided in the coater main body, and an output from the mission device. The rotary is driven by the rotary to cut the slope and the edge of the old iron, and this cutting soil is sent to the old iron after cutting the slope, and the cutting soil sent by this rotary is applied to the old iron A side cover for preventing scattering of the cut soil sent out by the rotary is provided so as to be movable up and down by a parallel link, and the side cover is lowered when moving up and down.
