  Next, the operation and the like of the farm work machine 1 will be described.

  When the fixed machine frame 3 of the machine body 2 of the farm work machine 1 is connected to the rear part of the tractor via a three-point link (work machine lifting support device), and the entire farm work machine 1 is moved along the main fence by running the tractor, The top surface of the main fence is cut by the plurality of cutting claws 43 of the upper surface cutting means 41, and the surface of the paddle and the main fence is cultivated by the plurality of filling claws 25 of the embankment means 23, and the side surface on the rice paddy side of the marsh And raised on the top surface.

  Then, the embankment that has been raised on the main fence by the embankment means 23 is compacted by the eaves forming member 33 of the eaves formation means 31, thereby repairing the original eaves and forming a strong new eaves that are not easily collapsed. The That is, the embankment on the heel is compacted by the heel upper surface forming portion 34 to form the heel upper surface, and the embankment on the heel is compacted by the heel shoulder surface forming portion 35 to form the heel shoulder surface. In the formation part 36, the embankment on the main fence is compacted to form the side face of the fence.

  Here, from the state in which the embankment means 23 shown in FIG. 3 is located at the normal position, the embankment means 23 is raised to the raised position as shown in FIG. Thus, even if the embankment means 23 is lowered to the lowered position, the vertical position of the upper surface cutting means 41 with respect to the ridge forming means 31 is kept constant, and the working depth by the upper surface cutting means 41 is kept constant.

  That is, as shown in FIG. 4, the operation of the electric hydraulic cylinder 48 of the embankment means lifting / lowering means 45 causes the first transmission case 21 to rotate upward with respect to the case connecting portion 16, and the embankment means 23 becomes the ridge forming means 31. However, even if the desired amount is increased, the expansion / contraction part 52 is extended by the operation of the drive part 53 of the position maintaining means 51 based on the control of the control means, so that the second transmission case 22 moves downward with respect to the first transmission case 21. Rotating, the vertical position of the upper surface cutting means 41 with respect to the ridge forming means 31 is kept constant.

  Further, as shown in FIG. 5, the operation of the electric hydraulic cylinder 48 of the embankment means lifting / lowering means 45 causes the first transmission case 21 to rotate downward with respect to the case connecting portion 16, and the embankment means 23 becomes the ridge forming means 31. Even if the desired amount is lowered, the expansion / contraction part 52 is contracted by the operation of the drive part 53 of the position maintaining means 51 based on the control of the control means, and the second transmission case 22 is moved upward with respect to the first transmission case 21. Rotating, the vertical position of the upper surface cutting means 41 with respect to the ridge forming means 31 is kept constant.

  And according to such a farming machine 1, the position maintenance which maintains the up-down direction position with respect to the ridge forming means 31 of the upper surface cutting means 41 is constant irrespective of the change of the up-down direction position with respect to the ridge forming means 31 of the embankment means 23. Since the means 51 is provided, even if the vertical position of the embankment means 23 with respect to the ridge forming means 31 is changed according to the soil quality of the ridge, the vertical position of the upper surface cutting means 41 with respect to the ridge forming means 31 does not change, and the upper surface The working depth of the cutting means 41 can be kept constant, and the upper surface cutting means 41 can appropriately cut the upper surface portion of the main bar.

  As shown in FIG. 6, the position maintaining means 51 may be constituted by an electric hydraulic cylinder 61.

One end of the telescopic part 64 is rotatably attached to the frame part 17 of the body 2 via the shaft 54, and the other end of the telescopic part 64 is attached to the attached part 22 a of the second transmission case 22 with the shaft 55. It is attached so that rotation is possible. The electric hydraulic cylinder 61 of the position maintaining means 51 and the electric hydraulic cylinder 48 of the embankment means raising / lowering means 45 are electrically connected to a control means 66 such as a controller.

  Then, from the state in which the embankment means 23 shown in FIG. 7 is located at the normal position, the embankment means 23 is raised to the raised position as shown in FIG. Even if the embankment means 23 is lowered to the lowered position, the vertical position of the upper surface cutting means 41 with respect to the ridge forming means 31 is kept constant, and the working depth by the upper surface cutting means 41 is kept constant.

  That is, as shown in FIG. 8, the operation of the electric hydraulic cylinder 48 of the embankment means lifting / lowering means 45 causes the first transmission case 21 to rotate upward with respect to the case connecting portion 16, and the embankment means 23 becomes the ridge forming means 31. Even if the desired amount is increased, the expansion / contraction part 64 is extended by the operation of the electrohydraulic cylinder 61 of the position maintaining means 51 based on the control of the control means 66, and the second transmission case 22 is lowered with respect to the first transmission case 21. And the vertical position of the upper surface cutting means 41 with respect to the ridge forming means 31 is maintained constant.

  Further, as shown in FIG. 9, the operation of the electric hydraulic cylinder 48 of the embankment means lifting / lowering means 45 causes the first transmission case 21 to rotate downward with respect to the case connecting portion 16, and the embankment means 23 becomes the ridge forming means 31. Even if the desired amount is lowered, the expansion / contraction part 64 contracts due to the operation of the electrohydraulic cylinder 61 of the position maintaining means 51 based on the control of the control means 66, and the second transmission case 22 moves upward with respect to the first transmission case 21. And the vertical position of the upper surface cutting means 41 with respect to the ridge forming means 31 is maintained constant.

  Accordingly, in the agricultural machine 1 shown in FIG. 6, as in the case shown in FIG. 1, the vertical position of the top cutting means 41 relative to the ridge forming means 31 regardless of the change in the vertical position of the embankment means 23 relative to the ridge forming means 31. Since the position maintaining means 51 is maintained to maintain a constant level, even if the vertical position of the embankment means 23 with respect to the ridge forming means 31 is changed according to the soil quality, etc. The position does not change, the working depth of the upper surface cutting means 41 can be kept constant, and the upper surface cutting means 41 can appropriately cut the upper surface portion of the main bar.

  In the above embodiment, the configuration in which the vertical position of the embankment means 23 with respect to the eaves forming means 31 is changed by the electric hydraulic cylinder 48 has been described. However, for example, the embedding means 23 forms the eaves by operating the handle or the like by an operator. You may make it raise / lower with respect to the means 31. FIG.
