Formed boundary portion 13; A suction cutting blade portion 14 formed to be inclined downward to narrow the width to the horizontal cutting blade portion 15 based on the boundary portion 13; It consists of a grinding cutting blade 16 formed to be inclined upwardly to narrow the width to the horizontal cutting blade 17 on the basis of the boundary portion (13).

The semi-circular groove 18 is formed at the end of the boundary portion 13 so that the material of the ground can be easily sucked upward.

The blade portion 12 is formed in a sawtooth shape by the inclined concave-convex portion 12a is inclined, so that the cutter portion 12 is maintained in the same state by the concave-convex portion 12a even when the blade portion 12 is worn. It can be used for a long time.

The horizontal cutting blades 15 and 17 formed at the ends of the blade portion 12 serve as cutting portions to be cut, and the suction cutting blades 14 and the grinding cutting blades 16 formed to be inclined downward are As in the intake 되도록, a negative pressure that sucks the cutting object to the upper part by the rotational force is generated. The cutting object sucked to the upper part of the cutter 10 rotates with air, and the grinding cutting blade part It hits 16 and is cut and crushed.

3A and 3B show an embodiment of the cutter 10 of the present invention. Figure 3a is a view showing a rod-shaped cutter 10, Figure 3b is a view showing a cutter 10 of the rectangular shape can be applied to a cutter of various shapes in addition to the cutting blade portion 14 is formed in the circumference Of course.

The cutter for generating the negative pressure of the present invention is a cutting and crushing means in a lawnmower, bee weed, forest fire extinguishing equipment for construction of lowland, debris weeds, etc. Can be used as

4 and 5 is an embodiment showing an apparatus using the cutter of the present invention as a cutting and grinding means, which is an opening 21 is formed at the bottom as shown, the negative pressure generating cutter 10 is A cover 20 vertically arranged at a predetermined distance from the ground on which the circumference of the opening 21 is reached; A suction passage 22 formed on one side of the cover 20; It relates to a pulverization apparatus using a negative pressure generating cutter comprising a; dust collecting unit 30 connected to the suction passage (22).

The shaft hole 11 of the cutter 10 is installed in the drive shaft portion 43 to which the driving force of the engine 40 is transmitted by the wire 41. The engine 40, the wire 41, and the wire ( The gripping pipe 42 and the drive shaft portion 43 through which the 41 passes can be used as it is.
