砕土装置を提供するものである。Generally, a tilling claw is attached to the rotary shaft of a rotary device via a claw attachment part, and by rotating the tilling claw in the forward direction with respect to the direction of travel, tilling, crushing, etc.
The so-called down-cut cultivation method, which involves plowing and other operations,
By rotating the rotary shaft equipped with the tilling claws in the opposite direction to the direction of travel, the tilling claws perform tillage and soil crushing work while cutting the soil from the bottom of the pail toward the ground surface.
A cultivation method called the so-called upcut cultivation method is known. ■Problem to be solved by the invention 1 However, the up-cut 11 method in rotary tillage equipment requires less tilling energy and specific energy than the down-cut tilling method, but since the tilling reaction force is directed backwards, the tractor In addition, if the soil cut by the tiller claws is not thrown backwards, clods of soil will remain within the rotary action area and will be re-tilled, increasing the energy required for tilling. Therefore, while the conventional up-cut 11 method has the advantages of lower cutting resistance and deeper plowing than the down-cut tillage method, it also has the disadvantages of inferior backward throwing effect of cut soil, etc.
There are many practical problems, which are the reasons for the delay in widespread use. The present invention improves the drawbacks of the conventional upcut phase method described above, improves the backward throwing effect of cut soil, and also rotates the rotary shaft in the forward direction after deep plowing by the upcut cultivation method. The purpose of rotary tillage is to improve the surface crushing effect of
The company provides soil crushing equipment.

A horizontal blade part 8b is formed which is bent in an L-shape with the tip end thereof being substantially perpendicular to one side with respect to the vertical blade part 8a, and a proper blade edge is formed on the side edge in the rotational direction from the vertical blade part 8a to the horizontal blade part 8b. is formed. The outer peripheral side starting end 8c forming the horizontal blade part 8b of the tilling claw 8 is rotated forward by α degrees (approximately 45 degrees) from the straight line l passing through the rotation center O of the rotary shaft 5 and the attachment hole 8d of the tilling claw 8. Located at the intersection of the inclined line n and the claw rotation radius R,
The inner peripheral side starting end 8e of the horizontal blade part 81) is located on a line P inclined 0 degrees (approximately 30 degrees) toward the rotational direction from the line n, and the starting end 8c of the horizontal blade part 8b is . Therefore, the tilling claws 8 can be rotated in the forward direction by rotating the rake shaft 5 in the reverse direction to perform up-cut tillage work, and by positioning the axis of the J-tally shaft 5 above the ground surface. By doing so, the surface of the soil tilled by the -El upcut tilling method is struck by the back surface of the horizontal blade portion 8h, making it possible to work on the frame. Here, an embodiment has been described in which the horizontal blade portion 8b of the tilling claw 8 is forged integrally with the vertical blade portion 8a.
In order to improve the strength of the base of the tilling claw 8, the horizontal blade part 8b is welded to a round bar, square timber, or pipe material, or the horizontal blade part 8b is removably fixed so that the worn horizontal blade part 8b can be replaced. It is also possible to adjust the mounting angle of the portion 8b. In addition, since the arcuate rake face formed on the horizontal blade part 8b of the tilling claw 8 is subject to severe wear, the rake face of the horizontal blade part 8h and a predetermined range of the vertical blade part 8a are made of a wear-resistant alloy. For example, a coating 9 may be applied, or two layers of wear-resistant materials made of different materials may be laminated together. Chain case 4 that transmits driving force to the rotary shaft 5
is inclined so that the rotary shaft 5 side is closer to the traveling direction, and a soil adhesion prevention plate 10 made of an elastic material made of rubber or plastic is attached to the front of the chain case 4, as shown in FIG. It is being Further, above the chain case 4 and below the gear box 2, a rotary cover 11 suitable for discharging backward the clod of soil cut and thrown by the tilling claws 8 is installed. These include a shield cover 12 installed above the claw rotation part, a side cover 13 that covers both sides of the plowing width of the rotary shaft 5, a front cover 14 installed in front of the shield cover 12, and a rear cover of the shield cover 12. It is comprised of an apron 15 attached to the side cover 13 so as to be movable up and down, and a sub-side cover 16 attached to the side cover 13 so as to be movable up and down. The shape of the shield cover 12 is such that the clearance between the tip of the tilling claw 8 and the shield cover 12 is minimized at a position slightly forward of the uppermost position of the mold rotation locus R, and the shield cover 12 is inclined to widen toward the rear from this point. It is designed to improve the effect of throwing soil clods during up-cut tillage. Next, a description will be given of operations performed by the tillage/soil crushing device configured as described above. First, the tilling claws 8 are formed into a shape suitable for up-cut tillage, and the rotary shaft 5 to which the tilling claws 8 are fixed is located in front of the chain case 4.
In the up-cut tillage method according to the present invention, the rotary shaft 5 is positioned below the ground surface G, and the H/R (L1 is the plowing depth and R is the claw rotation radius) is set to 1. It is possible to further develop the above. Therefore, as the tilling claws 8 cut the tilled soil from the bottom of the tiller toward the ground surface, the cut soil clods become sliced, and cracks occur in the soil clods near the ground surface.
1) While sliding on the rake surface, it is rotated in the opposite direction to the rotary shaft 5 and thrown backward. At this time, a part of the cut soil clod is held in the scoop of the horizontal blade part 8b and is thrown backwards through the inside of the C claw rotation trajectory without leaving the cut soil within the action area of the rotary knife. Therefore, almost no clod is deposited in front of the rotary shaft 5. In addition, when the clod thrown by the horizontal blade part 8b passes through the outer circumference of the claw rotation trajectory, it hits the shield cover 12 behind the minimum clearance position, which is slightly forward of the top end of the claw rotation trajectory, and is crushed. Since the chain case 4 and the rotary shaft 5 are tilted and fall behind the rotary shaft 5, clods of earth that increase running resistance and traction resistance are not accumulated in front of the chain case 4 and in front of the rotary shaft 5. Moreover, after carrying out tilling work with the above-mentioned plowing claws 8,
As shown in Fig. 5, when the axis of the rotary shaft 5 is located above the ground surface G and the H/R is 1 or less and the rotation is made in the positive direction by 1 no, the surface of the soil that has been excavated will be horizontal. Work on the frame is performed by being struck by the back of the rake face of the blade portion 8b. In place of the above-mentioned tilling claws 8, tilling claws 8' shown in FIGS. 6 and 7 may be attached to the claw attachment portion 6. This tilling claw 8' is provided with draining arcs 8f and 8g formed on both side edges of the vertical blade portion 8a', although the reference numbers of the parts corresponding to the above-mentioned tilling claw 8 are marked with dashes and the explanation is omitted. There is. Therefore, during both up-cutting and down-cutting operations, the Ijl intertwining arc 8f. 89 reduces the cutting resistance of the soil, and also improves the ability to drain straw, etc., especially during down cutting. Effects of the Invention As described above in detail based on the embodiments, the soil crushing device according to the present invention has an L-shape in which the tip side faces the vertical blade portion and is substantially perpendicular to one side. Form a horizontal blade part bent to
Position it at the intersection of the slightly inclined line and the die rotation radius, and also position the inner circumferential side starting end on a line inclined by β degree toward the rotation rear from the line passing through the rotation center of the rotary shaft and the outer circumferential side starting end. , comprising a tilling claw formed by forming a smooth arc-shaped rake between the outer circumferential side starting end and the inner circumferential starting end of the horizontal blade part,
During up-cut tillage, the rotary shaft is configured to rotate its axis below the ground surface, improving the effect of cutting and removing soil clods from the ground, improving the effect of cutting and removing 1'l of soil, and removing 110ml of soil without re-tilling. This will reduce energy consumption and allow for deeper plowing. Further, the surface of cultivated soil can be effectively crushed simply by positioning the axis of the rotary shaft of the above-mentioned soil crushing device above the ground surface and rotating it in the forward direction.
