The cover 32 of the polyhedral drum 30 is provided with a grip 40 for rotating the working unit.
[0016]
In the plastering machine 1 having such a configuration, a lower link of a three-point link is connected to the lower link connecting portion 3 and a top link is connected to the top mast at the rear portion of the tractor (not shown), and a universal joint, Power is transmitted to the input shaft 5 through the transmission shaft and the universal joint. When the wrinkle coater 1 performs a trimming operation, the pretreatment body 6 and the trimming body 7 are rotated about the inclined shaft 9 by the chain case 8 to the state shown in FIGS. At this time, in the chain case 8, as shown in FIG. 3, the front end portion of the input portion case 13 is engaged with the rear end portion of the output shaft case 10, and the clutch 15 is in a connected state. The slide rod 34 is fixed by a pin 35 b of the fixing device 35. The power received by the input shaft 5 in this state is transmitted to the pretreatment body 6 through the path of the chain transmission system 12 -output shaft 11 -clutch 15 -input shaft 14 -sprockets 17 and 19 -output shaft 18 and output. The shaft 18, the universal joint 24, and the differential case 22 are transmitted to the trimming body 7. Then, as the tractor 2 travels, trimming work is performed.
[0017]
When adjusting the working depth of the tilling claw 25 and the earthing plate 26 of the pretreatment body 6, the pretreatment body vertical adjustment device 28 is used. Further, when adjusting the working depth of the polygonal conical drum 30 of the trimming body 7, the trimming body vertical adjustment device 33 is used. Furthermore, when adjusting the working depth of the pretreatment body 6 and the trimming body 7 at the same time, it can be performed by changing the support height of the coater 1 by the lower link of the tractor. This is done by moving the grounding wheel 37 up and down by the wheel up / down adjustment mechanism 37a.
[0018]
In the pretreatment body 6, a part of the main fence and the field are cultivated by the tilling claws 25, and are raised in a bowl shape with respect to the main fence side by the earthing plate 26. The polygonal surface of the polygon is rotated eccentrically and strikes the slope surface to form the desired surface. Further, the top of the ridge formed by the polygonal conical drum 30 is formed flat by the horizontal cylinder 31. During this trimming operation, the eccentrically rotating polygonal cone drum 30 is supported in a stable state by a ground ring 37 provided on an axis close to the rotation axis of the polygonal cone drum 30 and the horizontal cylindrical body 31. . An extension is attached to the horizontal cylinder 31 as necessary.
[0019]
When the carburizing machine 1 does not work and travels on the road connected to the tractor and lifted by the three-point link, first, the finger hooking part 35a of the fixing device 35 resists the elastic force of the spring 35c. The pin 35b is extracted from the engagement hole 34b provided in the piston portion 34a of the slide rod 34, and has a grip 40 for rotating the working portion, and the chain case 8 together with the pretreatment body 6 and the adjusting body 7 is centered on the inclined shaft 9. It rotates and moves the pre-processing body 6 and the trimming body 7 to a non-working position (FIGS. 5-7). At this time, the input unit case 13 rotates together with the chain case 8 and is separated from the output shaft case 10, and the clutch 15 is disconnected. When the pretreatment body 6 and the trimming body 7 reach the non-working position, the pin 35b of the fixing device 35 fixes the slide rod 34 by the biasing force of the spring 35c. When the pre-processing body 6 and the trimming body 7 are rotated and moved from the working position to the non-working position or the second working position, or from the non-working position or the second working position to the working position, the gas spring 36 assists. By operating, the rotation operation of the chain case 8 is performed lightly. Further, the pretreatment body 6 and the trimming body 7 are prevented from being rapidly lowered by their own weight.
