JPH10151606A - Chipper for chipping mixed bough, branch and leaf - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a chipper for chipping mixed boughs, branches and leaves, which prevents an overload from being applied on blades, further cuts chips obtained by primary cut to pieces, and is provided with a means capable of safely supplying branches and leaves to the blades. SOLUTION: Each rotary blade is composed of a tearing blade 10 for snapping into a material so as to tear it off and a shaving blade 9 for laterally shaving the torn material relative to the tear thereof, thereby reducing a shaving force of the edge of the blade. Further, a countermeasure is taken so that shaved chips loosen and become small in spacings among edges of the tearing blade by performing chip-cutting with a multiple of edges of the tearing blade provided longitudinally against the shaving blade and in front of the shaving blade in its rotary direction so as to part the width of the shaving blade. A further countermeasure is taken so that the snapping depth of the blade is adjusted suitably so as not to apply an overload on the blade by providing a suitable gap between a base blade 7 for checking the material to be chipped and a circumference of a shaft on which the tearing blades and the shaving blades are disposed, and which restricts the snap of the tearing blades. In the case of cutting spread branches and leaves, materials bridging on a side wall of an introducing hopper are supplied to the rotary blades by providing a feeding belt 5 on the side wall of the introducing hopper and driving the belt by handle operation from the external side.

Means for Solving the Problems In order to solve the above problems and achieve the above object, the present invention employs the following technical means. That is, the twig-and-leaf mixing chipper machine of the present application is used for cutting pruned branches and thinned wood, etc.
The structure of the rotating blade is such that a cutting blade that cuts into the material in a tearing manner, and a material that has been torn is cut laterally with respect to the tear with a cutting blade. By cutting a number of cutting edges vertically in front of the cutting blade and cutting the chip so as to split the width of the cutting blade, the chipped chip becomes uneven and smaller at the interval between the cutting edges. Take measures to reduce the size of chips.

[0005] When the material is fed vigorously, or when the material is cut short and falls down and hits the blade widely, the shaft-shaped blade having the blade for holding the chip material, the tear blade and the cutting blade is mounted. An overload preventing means is provided in which a gap is appropriately provided with the perimeter of the cut-in control, and the material to be chip-cut is received in the perimeter of the cut-in control to make the depth of the blade bite appropriately. When cutting widespread branches and leaves such as pruned branches and thinned wood, feed the bridging material on the side wall of the introduction hopper to the rotating blade, and provide a feed belt on the side wall of the introduction hopper. A branch-and-leaf feeding means is provided which is driven and fed, or driven and driven by power.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS By using such a means, even if a chip is cut with a wide shaving blade, the chip can be made smaller and smaller at intervals between the cutting edges. Even when the material is thrown in vigorously or when the material is cut and shortened and falls over and hits the blade broadly, it can be received around the bite control, and the bite depth of the tearing blade and shaving blade can be appropriately regulated, and No digging overload occurs. By providing a feed belt on the side wall of the introduction hopper and driving it from the outside, it is possible to easily and safely feed pruning branches and thinning materials, such as pruned branches and thinned wood, to the rotating blades.

[0010]

According to the present invention, the following effects can be obtained. Since it was made as in claim 1, even with a relatively thick material, the tearing blade cuts in the way of the wedge principle so that it cuts, the biting force is small, and by shaving the part where the tissue of the material has been torn, The force on the cutting blade is also reduced. As a result, it is possible to cut a relatively thick tip with a chipper machine smaller than before. In addition, a large number of cutting edges are provided so as to divide the width of the cutting blade, and by cutting the chips with a combination of these blades, the chips that have been cut will be broken at the interval between the cutting edges, and only the primary cut will be performed. You can get fine chips.

According to the second aspect of the present invention, the gap between the cutting blade for holding down the material and the cutting edge around which the tearing blade and the cutting blade are attached is always properly maintained, and the blade and the cutting blade rotate. By properly maintaining the depth of penetration and not overloading the rotating shaft, it becomes possible to cut the twigs with a small chipper machine. By being configured as in claim 3,
When cutting widespread leaves such as thinned wood, it is possible to easily and safely feed the material bridging to the introduction hopper side wall toward the rotating blade.
