BACKGROUND OF THE INVENTION
The present invention relates to a coater equipped with a trimming body and a pretreatment body that are mounted on the rear part of a traveling machine body and driven by receiving power from the traveling machine body, and in particular, the trimming body and the pretreatment body are attached so as to be offset. About things.
[0002]
[Prior art]
Conventionally, a pre-treatment body that is attached to the rear part of a traveling machine body, receives power from the traveling machine body, cultivates the main fence and the field and raises it into a bowl shape, and the soil cultivated by this pre-treatment body while rotating the soil 2. Description of the Related Art A wrinkle coater having a drum-shaped trimming body to be molded and configured so that a pretreatment body and a trimming body can be offset left and right with respect to a main body is well known.
[0003]
Various configurations can be considered for offsetting the pretreatment body and the trimming body to the left and right with respect to the main body. For example, a manual cylinder mechanism is used as a means for adjusting the offset amount of the pretreatment body and the trimming body. It has been generally known to use.
[0004]
[Problems to be solved by the invention]
In the above-mentioned manual cylinder mechanism, the rod inserted into the cylinder of the cylinder mechanism is moved, the lock pin is inserted and fixed to the cylinder and the rod, and the offset amount of the pretreatment body and the adjusting body is adjusted. However, since the locking pin is a rigid body, if the processing accuracy of the cylinder and the rod is poor, the insertion holes of the cylinder and the rod are difficult to fit with each other, and the operation is troublesome. In addition, rattling occurs between the cylinder and the rod, generating noise and damaging the rod and pin. The present invention has been made for the purpose of solving such problems.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a pre-processing body that is attached to the rear part of a traveling machine body, receives power from the traveling machine body, cultivates the main fence and the field and raises it in a bowl shape, and the pre-processing body. In a basket coater comprising a drum-shaped trimming body that is formed into a kite while rotating the cultivated soil, and configured so that the pretreatment body and the trimming body can be offset left and right with respect to the main body,
A support frame of the pretreatment body and the trimming body is supported to be movable in the left-right direction via a parallel link with respect to the main body, and a cylinder mechanism is provided between the support frame and one of the parallel links, The offset amount of the trimming body can be adjusted, and a resilient cushion member is provided at the tip of the rod fitted into the cylinder of the cylinder mechanism.
[0006]
[Action]
With the above configuration, when the offset amount of the pretreatment body and the trimming body is adjusted, the brush coating machine of the present invention extracts the lock pin and moves the rod relative to the cylinder, and locks it in the cylinder and the rod insertion hole. The hole alignment of the cylinder and the rod insertion hole when inserting the pin for use is easily performed by moving the rod slightly by the cushion member, and the operation can be performed in a short time. Further, since the rod is in contact with the cylinder through the cushion member, the buffering action does not generate noise and damage the rod and the pin.

The pretreatment body 7 cultivates a part of the cocoon and the field and raises it into a cocoon shape, and the cultivated soil rotates while the polygonal ridgeline and the plane portion of the polygonal cone drum 8 are decentered. Then tap the slope to mold it into a bowl.
[0018]
In polygonal conical drum 8, although its base 8a is mounted by fixing bolts 18 against the drum boss movement, the mounting surface to Doramubo scan of Seiazetai base 8a in the circumferential direction with respect to the drum mounting surface of the drum boss Then, by fixing with the fixing bolt 18, the amount of eccentricity (runout width) of the trimming body 8 can be changed within a predetermined range (in three stages in the embodiment) .
[0019]
Then, the pre-treatment body 7 changes the swing width of the polygonal cone drum 8 according to the soil quality and moisture of the soil that is cultivated by the pre-treatment body 7 and cultivates it in a bowl-like shape, and appropriately adjusts it according to the soil quality and soil moisture.畦 Work is done. In addition, when it is better to offset the pretreatment body 7 and the trimming body 8 according to the shape of the field and the state of the soil, the cylinder 22a, the rod 22b, the lock pin 22c of the cylinder mechanism 22 for adjusting the offset amount. , to adjust the amount of offset by operating the stopper pin 20d, it is possible to perform integer ridges work with the appropriate state.
[0020]
【The invention's effect】
As described above, according to the plastering machine of the present invention, the support frame of the pretreatment body and the trimming body is supported so as to be movable in the left-right direction via the parallel link to the main body, and the parallel link to the support frame Since the cylinder mechanism is provided between the front end of the rod and the offset amount of the pretreatment body and the trimming body can be adjusted, and the elastic cushion member is provided at the tip of the rod inserted into the cylinder of the cylinder mechanism. When adjusting the offset amount of the processing body and trimming body, remove the lock pin, move the rod relative to the cylinder, and insert the lock pin into the cylinder and rod insertion hole. The hole alignment can be easily performed by moving the rod slightly by the cushion member, and can be operated in a short time. In addition, since the rod is in contact with the cylinder via the cushion member, it is possible to prevent the buffering action from generating noise and damaging the rod and the pin.
