Then, the pretreatment body 15 and the trimming body 16 are rotated in a stepless manner within a range of 180 degrees from the position of FIG. 1 through the position of FIG. 5 to the position of FIG.
[0014]
The upper sides of the pretreatment body 15 and the trimming body 16 are covered with a pretreatment body cover 15a and a trimming body cover 16a. Of these, the pretreatment body cover 15a is slid in the left-right direction by the left-right slide adjustment handle 22 to adjust the discharge direction of the cultivated soil. The pretreatment body 15 can also be adjusted up and down (plowing depth adjustment). On the other hand, a trimming body vertical adjustment device 23 is provided in the vicinity of the trimming body 16, and vertical adjustment of the trimming body 16 is performed. In addition, a triangular disc-shaped gauge wheel 24 is vertically adjusted at the end of the transmission case 17 by the vertical adjustment handle 25, and the entire pretreatment body 15 and trimming body 16 are vertically adjusted.
[0015]
In the coater 1 having such a configuration, the top link connecting portion and the lower link connecting portions 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 3. The motive power is transmitted, the motive power is shifted by the transmission gear box 7, and transmitted to the pretreatment body 15 and the adjusting body 16 through the transmission frame 8 and the transmission case 17, and rotated to perform the respective operations.
[0016]
In the pretreatment body 15, a part of the main fence and the field are cultivated by the tiller rotor 14 and raised in a bowl shape with respect to the main fence, and the cultivated soil is put on the polygonal cone drum of the adjusting body 16. The polygonal ridgeline and the flat part rotate to strike the slope and form it into a bowl. In addition, a horizontal cylindrical body provided integrally with the polygonal cone drum rotates and contacts the top of the heel so as to level the top of the heel.
[0017]
1 is normally set in the state shown in FIG. 1 and rotates counterclockwise while moving in the direction of the arrow, and forms a basket on the right side of the basket coater 1. When it is intended to form cocoons with high accuracy at the corners of the field, etc., the drive rotation of the pretreatment body 15 and the rectifying body 16 is temporarily stopped, and the cocoon coater 1 is lifted by the three-point link connecting mechanism of the tractor. The cylinder 21 is extended. Then, the transmission frame 8 rotates in the horizontal direction around the base end portion via the link body 20, and the pretreatment body 15 and the trimming body 16 pass from the position of FIG. 1 to the position of FIG. Move 180 degrees to position. At this time, the electric cylinder 21 and the link body 20 operate in order as shown in FIGS. Then, the coater 1 drives the pretreatment body 15 and the trimming body 16 in the state of FIG. 6, moves the tractor back to the side where the kite is to be formed, and moves the coater 1 in the direction of the arrow. By performing the above, highly accurate wrinkle formation is performed up to the edge.
