Steplessly until the processing body 19 and the trimming body 20 are rotated 180 degrees and offset to the left side, and the pretreatment body 19 and the trimming body 20 of FIG. 6 are rotated 180 degrees and brought close to the center of the machine body. Adjustable.
[0011]
As shown in FIG. 3, a link body 25 pivotally attached by a transmission frame side pivot part 23 and a main body frame side pivot part 24 is provided at the base end part of the transmission frame 12. An electric cylinder 26 is interposed between the support / transmission frame 7. When the electric cylinder 26 is expanded and contracted, the link body 25 rotates about the main body frame side pivot 24 and the transmission frame 12 rotates about the base end portion with the transmission frame side pivot 23. The pretreatment body 19 and the trimming body 20 are rotationally moved within a range of 180 degrees steplessly from the position of FIG. 1 to the positions of FIGS. 5 and 6.
[0012]
The upper sides of the pretreatment body 19 and the trimming body 20 are covered with a pretreatment body cover 19a and a trimming body cover 20a. Of these, the pretreatment body cover 19a is slid in the left-right direction by the left-right slide adjustment handle 27 to adjust the discharge direction of the cultivated soil. The pretreatment body 19 can also be adjusted up and down (plowing depth adjustment). On the other hand, a trimming body vertical adjustment device 28 is provided in the vicinity of the trimming body 20, and the vertical trimming of the trimming body 20 is performed. In addition, a triangular disc-shaped gauge wheel 29 is vertically adjusted at the end of the transmission case 21 by the vertical adjustment handle 30, and the whole of the pretreatment body 19 and the trimming body 20 is vertically adjusted.
[0013]
In the coater 1 having such a configuration, the top link connecting part 3 and the lower link connecting parts 4 and 4 of the coater 1 are connected to the three-point link connecting mechanism of the tractor, and the PTO shaft of the tractor is connected to the input shaft.

[0014]
In the pretreatment body 19, a part of the cocoon and the field are cultivated by the cultivating rotor 18, and the cultivated soil is raised to a cocoon shape. The polygonal ridgeline and the flat part rotate to strike the slope and form it into a bowl. Moreover, the horizontal cylindrical body 20b provided integrally with the polygonal cone-shaped drum is in contact with the top of the heel while rotating, thereby leveling the top of the heel.
[0015]
The paddy machine 1 of this embodiment is usually set to the right side of the machine body in the state of FIGS. 1 and 2 with the pretreatment body 19 and the trimming body 20 being moved in the forward direction and turning counterclockwise, A ridge is formed on the right side of the machine 1. When it is intended to form cocoons with high accuracy in the corners of the field, etc., the drive rotation of the pretreatment body 19 and the rectifying body 20 is temporarily stopped, and the cocoon coater 1 is lifted by the tractor three-point link connection mechanism to The cylinder 26 is extended. Then, the transmission frame 12 rotates horizontally around the base end portion via the link body 25, and the pretreatment body 19 and the trimming body 20 are rotated 180 degrees from the position of FIG. 1 to the position of FIG. To do. At this time, the electric cylinder 26 and the link body 25 operate in order as shown in FIGS. 5 or 6 drives the pretreatment body 19 and the trimming body 20 to move the tractor back to the side where the cocoon is to be formed and move the glazing machine 1 in the direction of the arrow. By carrying out the operation while making it work, a highly accurate ridge formation is performed to the edge.
[0016]
When adjusting the offset amount of the coater 1 according to the size (width) of the tractor to which the coater 1 is attached, the state of the field, the soil quality, etc., the parallel link is obtained by extending or contracting the electric cylinder 22 for adjusting the offset amount. 5 and 6 are rotated in the left-right direction to move the wrinkle coater 1 in the horizontal direction, and the amount of offset can be adjusted arbitrarily to perform appropriate trimming work.

【The invention's effect】
As described above, according to the plastering machine of the present invention, the following effects can be obtained.
[0018]
The pretreatment body and the trimming body can be rotated 180 degrees horizontally via a link body provided at the base of the transmission frame with the transmission frame as the center of rotation, and the base side of the transmission frame is set to the main body frame. Since the horizontal offset amount is supported via a parallel link, the pretreatment body and the trimming body can be rotated 180 degrees horizontally around the transmission frame as well as the normal trimming operation. Thus, it is possible to perform the wrinkle shaping work up to the heel by working while backing the traveling machine body and the wrinkle coater. Further, the amount of offset in the horizontal direction of the pretreatment body and the trimming body can be freely adjusted, so that the trimming operation can be performed at an appropriate position according to the width of the tractor.
