【考案の詳細な説明】
この考案は、根株処理装置、例えばトラクタ等
による造林作業の際に障害となる根株を削り取る
ために、作業車両等に取付けて使用される根株処
理装置に関する。[Detailed Description of the Invention] This invention relates to a root stock processing device, for example, a root stock processing device that is attached to a work vehicle or the like and used in order to scrape off roots that become an obstacle during afforestation work using a tractor or the like.
この種の根株処理装置として、回転円板の下面
に複数のカツタが設けられたものが知られている
が、従来の装置では、回転円板およびカツタが一

い。すなわち、カツタの所要切削動力はカツタの
切削速度と切削抵抗との積に比例するが、上記の

所要切削動力もこれに比例して大きくなる。 This type of root treatment device is known to have a plurality of cutters installed on the underside of a rotating disk, but in conventional devices, the rotating disk and cutters are integrated, so manufacturing and Polishing the cutting blade is not easy. In addition, in this type of equipment whose purpose is to perform work efficiently using a machine with a constant output, it is desirable that all cutters require the same amount of cutting power, but with conventional equipment, Since the inclination angle of the cutting edge with respect to a plane perpendicular to the direction of movement of the cutter is constant for all cutters, and approximately equal cutting resistance acts on all cutters, the above requirement cannot be met. In other words, the required cutting power of the cutter is proportional to the product of the cutter's cutting speed and the cutting resistance, but as mentioned above, the cutting resistance of each cutter is almost equal, and as you go from the center of the rotating disk to the outer periphery, the cutter's cutting power increases. Since the cutting speed, that is, the circumferential speed increases, the required cutting power of the cutter also increases in proportion to this.

装置を提供することを目的とする。 This idea was made in view of the above-mentioned circumstances, and is a rational method that makes it easy to manufacture the cutters and polish the cutting blades, and to make the required cutting power for all the cutters approximately equal. The purpose of the present invention is to provide a root stock treatment device.

動力も全てのカツタについてほぼ等しくなる。 The root stock treatment device includes a rotating disk 1 that is horizontally attached to a work vehicle or the like, and has a rotary disk 1 on the bottom surface of the disk 1.
A plurality of root treatment cutters 2 are detachably attached at predetermined intervals in the circumferential direction and radial direction. Each cutter 2 includes a block-shaped cutter body 3 that is detachably attached to the disc 1 with a bolt, a flat cutting blade 4 that is detachably attached to the body 3 with a bolt, and a cutter body 3 that is detachably attached to the body 3 with a bolt. It consists of an attached groove cutting blade 5.
The cutting edge 6 of the groove cutting blade 5 protrudes downward from the cutting edge 7 of the flat cutting blade 4, and when the disk 1 is rotated and lowered to approach the upper surface of the root, the groove cutting blade 5 first The cutting blade 6 comes into contact with the upper surface of the root to cut a groove, and then the cutting edge 7 of the flat cutting blade 4 cuts the remaining part of the upper surface of the root into a flat shape. The cutting speed (hereinafter simply referred to as cutting speed) of the flat cutting blade 4, that is, the circumferential speed, increases from the center of the disk 1 toward the outer circumference. The cutting edge 7 of the flat cutting blade 4 is almost horizontal, and the inclination angle α of this cutting edge 7 with respect to a plane perpendicular to the direction of movement of the cutter 2 is
β and γ (hereinafter simply referred to as inclination angles) increase from the center of the disk 1 toward the outer circumference.
The cutting resistance acting on the flat cutting blade 4 (hereinafter simply referred to as cutting resistance) is maximum when the cutting blade 7 is perpendicular to the direction of movement, that is, when the inclination angle is zero, and increases as the inclination angle increases. It gradually becomes smaller. Therefore, the cutting force Fa of cutter 2 is
Fb.Fc becomes smaller as it goes from the inside of the disk 1 to the outside. The inclination angles α, β, and γ of each cutter 2 are:
The product of cutting speed and cutting resistance is determined to be approximately equal for all cutters 2, and therefore the required cutting power of each cutter 2, which is proportional to this product, is also approximately equal for all cutters.

とができる。 As described above, according to the root treatment device of this invention, the cutter 2 is detachable from the rotary disk 1, so it is easy to manufacture, and the cutter 2 can be removed from the disk 1. Polishing work etc. can be easily carried out. In addition, since the angle of inclination of the cutting edge 7 of the flat cutting blade 4 with respect to the plane perpendicular to the direction of movement of the cutter 2 decreases from the center of the rotating disk 1 toward the outer circumference, the required cutting power of all the cutters is reduced. can be made almost equal, and the output of the device can be used effectively to cut the stump efficiently.
