はなかった。As a tillage/crushing compound work machine that combines a plow and a soil crushing device with rotating soil crushing blades, the soil crushing device crushes the soil embankment plowed by the plow. The crushing blade of the soil crushing device acts in the up-cut direction from the back side of the earthen embankment against an earthen embankment that is being guided by the earth to rise or is in the process of reversing. A rotating soil crushing blade acts in a down-cut direction against the soil embankment, scooping up the earth embankment and crushing the soil. Various methods are known, such as one in which a soil crushing device crushes the soil on an earthen embankment that has been reversed in the previous plowing process. This method was not sufficient in terms of eliminating the voids formed between the soil embankments that were turned up and down, and in efficiently crushing the upper surface of the soil v1Φ that was turned over until finely.

This depth of action is determined by supporting the above-mentioned support arm +8) - (9) on the support machine frame (supporting the machine frame so that it can freely rotate up and down against the force, and in a state where it is rotated by the desired amount). The supporting arms (8) and (9) are swung relative to the machine frame (1) as shown by the arrows in Fig. 1, and the cutting edge of the crushing blade QO) is In some cases, the lower edge of the rotation locus of the rotary blade 00 may be adjusted as desired by vertically adjusting the lower edge of the rotation locus. As shown in , the earth embankment (5) is driven and rotated so as to act in a down-cut direction. The soil crushing blade 0 also has a cutting edge that cuts into the soil jIL (5), scoops up a lump of soil from the cut earth embankment (5), and splashes it upward from the rear (left side in Figure 4). A lateral bend (10a) with a rising rake angle is formed. This side bend (10a) is such that when it cuts into the earth embankment (5) and moves the soil above it, the flow direction of the soil guides the earth embankment (5) by the plow (4). By forming the soil in the opposite direction to the direction in which it is being turned over, the movement of soil by plowing can be reversed when the soil is crushed. To return this soil, when installing the crushing blade (10) around the rotating shaft (6), the QOI of the crushing blade...
In some cases, this is done by arranging the soil to form a spiral that sends the soil in the return direction.

Reference numeral 20 denotes a level cover suspended vertically and rotatably from the rear edge of the cover. The blade edge of the Eido blade OI... installed behind the plow (4) is used to reverse the plowing by the plow (4), and the tip of the blade OI... is placed on the soil embankment (5) which is about to complete the reversal. Since it acts as if it cuts in while pressing downward, it ensures the reversal of the soil (5) and also collapses the large voids that occur between the soil embankments.

態が得られる特有の効果が撥揮出来る。And also the crushing blade a-shun, its rotation and plow (4)
As the soil progresses, the upper surface of the earthen embankment (5), which is being reversed one by one, is cut and thrown up from behind, and the large earth clods are smashed against the lattice-shaped frame rods, breaking them and lowered by the frame rods. The crushed soil is crushed against the inner surface of the upper cover C that holds the frame, and as it is further crushed, the coarse soil is guided down to the inner surface of the cover C. The crushed soil begins to accumulate. Also, during the crushing action of the crushing blade a1, the crushed soil moves in the opposite direction to the direction in which the earth embankment (5) is reversed and guided by the plow (4). The result of the work by the plow (4) according to the invention as well as the soil crushing blade a is that the lowermost layer is inverted by the plow (4). An earthen embankment with no large gates is arranged in the lower middle layer, a medium-sized earthen embankment with many cracks fractured by shear compression given by the guiding surface (42a) of the plow (4), etc. is in the upper middle layer. The layer is made up of fine soil grains that have been crushed by the crushing blade, and the top layer is the fine soil particles that have been sufficiently stirred and blown away by the crushing blade OI. 1. The bottom layer of these weir structures is too rough for crops. Because the upper layer is fine, drainage is good, and the seed bed is composed of fine soil particles, and the lower layer is also pressed appropriately to eliminate large voids, which allows for good moisture retention through capillary action. The proper proximity of the soil grains has the unique effect of preventing the runoff of fertilizers and achieving a favorable tillage condition.

れしいものと云える。The present invention has the secondary effect that the traction force of the plow can be reduced due to the reaction force generated by the work resistance such as crushing and pressing action of the soil crushing blade, since the rotation of the soil crushing blade is in the down-cut direction. It can be said that it is suitable for a multi-purpose work machine.
