  Next, the operation and the like of the above-described glazing machine 1 are described.

  When the coater 1 is connected to the rear three-point link of the tractor and the tractor moves forward, the coater 1 moves together with the tractor in the forward direction of travel (in the direction of the arrow in FIG. 1). It is restored and a new newspaper is formed. That is, the soil is raised by the tilling claws 62 and 92 on the side surface and the top surface of the main fence, and the embankment is compacted by the vertical side surface forming body 42 that rotates by the rotation center axis X as a center, and the inclined surface is formed. The fillet is compacted by the fillet upper surface forming body 43 formed with the dredging side surface and slip-rotating around the rotation center axis X, thereby forming a horizontal flat dredged surface.

  Further, at the corner of the field, when the driving means 15 is operated to switch from the forward working state shown in FIG. 1 to the return working state shown in FIG. It moves toward the front of the direction (in the direction of the arrow in FIG. 2), and as in the forward operation, the end portion of the main bar is repaired to form a new bag.

  Here, for example, when the plowing depth of the embankment body 3 is made shallower than the state of FIG. 4 according to conditions such as the soil quality of the marsh and the paddy surface, the operator holds the handle 77 of the adjusting means 76. Hold and rotate in one direction. Then, for example, as shown in FIG. 5, the expansion and contraction body 78 is contracted, and the embankment support frame 21 is translated upward with respect to the ridge-formation body support frame 22 accordingly. The tilling depth of the embankment body 3 becomes shallow while the posture is maintained constant.

  On the contrary, when the tilling depth of the embankment body 3 is increased as compared with the state of FIG. 4, the operator holds the handle 77 of the adjusting means 76 and rotates it in the other direction. Then, for example, as shown in FIG. 6, the stretchable body 78 extends, and the embankment support frame 21 translates downward with respect to the ridge-former support frame 22 accordingly. As a result, the work of the embankment 3 is performed. The tilling depth of the embankment body 3 is deepened while the posture is maintained constant.

  And according to such a bat coater 1, the embankment body 3 is moved parallel to the embankment body support frame 22, and the embankment body 3 is maintained with the working posture of the embankment body 3 maintained constant. Since the tillage depth can be adjusted, a certain tillage performance can be maintained, a desired embankment amount can be obtained, and thus a strong hail that is difficult to collapse can be formed.

  Further, by turning the handle 77 of the adjusting means 76, the tilling depth of the embankment body 3 can be easily adjusted while keeping the working posture of the embankment body 3 constant.

  In the above embodiment, the configuration has been described in which the adjustment means 76 has the expansion and contraction body 78 such as a vertical adjustment rod that is manually expanded and contracted. However, for example, as shown in FIG. A configuration having a telescopic body 101 such as a hydraulic cylinder may be used.

  A stretchable body 101 shown in FIG. 7 has a cylinder main body 102 and a rod 103 that goes in and out of the cylinder main body 102. The base end of the cylinder body 102 is connected to the ridge forming body support frame 22 so as to be rotatable about a horizontal axis 104, and the tip of the rod 103 is connected to the embankment support frame 21 in the horizontal horizontal axis. It is connected so as to be rotatable about 105.

  Then, when the operator presses, for example, a tillage depth adjustment button of an operation box which is a remote operation means (not shown), the expansion / contraction body 101 expands / contracts, and the embankment body support frame 21 forms a ridge according to the expansion / contraction of the expansion / contraction body 101 As a result, the plowing depth of the embankment body 3 is adjusted while the working posture of the embankment body 3 is maintained constant.

  Therefore, also in the glazing machine 1 shown in FIG. 7, the embankment body 3 is moved parallel to the embankment body support frame 22 so that the work body of the embankment body 3 is maintained at a constant level. Since the tillage depth can be adjusted, a certain tillage performance can be maintained, a desired embankment amount can be obtained, and thus a strong hail that is difficult to collapse can be formed.

  In the above-described embodiment, the configuration in which the portions on the embankment support frame 21 side of the both rotary arms 71 and 73 of the rotary connecting bodies 23 and 24 are connected by the reinforcing plates 72 and 74 has been described. As shown in FIG. 8, the reinforcing plates 72 and 74 allow the portions of the rotary arms 71 and 73 on the embankment support frame 21 side and the rotary arms 71 and 73 on the heel-forming body support frame 22 side. The structure which connected the parts mutually may be sufficient.

  Further, the shapes of the reinforcing plates 72 and 74 are arbitrary, and in addition to the longitudinal shape shown in FIGS. 7 and 8, the triangular plates such as the reinforcing plates 72a and 74a shown in FIG. A rectangular shape or a substantially rectangular shape having triangular notches 107 and 107 such as reinforcing plates 72b and 74b shown in FIG.

  Further, although the upper rotating connecting body 23 is not shown, for example, it may be configured by only one upper rotating arm.

  Furthermore, it is not always necessary that the rotating coupling bodies 23 and 24 that are paired are parallel to each other in a strict sense, and may be substantially parallel.

  Further, the pad coater 1 is limited to a configuration in which the embankment support frame 21 moves up and down in parallel so as to draw an arc with respect to the paddle forming body support frame 22 based on the rotation of the rotating coupling bodies 23 and 24. For example, although not shown, a configuration in which the embankment support frame 21 moves up and down in parallel with the ridge-former support frame 22 along a straight line in the vertical direction may be used.
