Abstract
The invention provides a circular saw blade and a cutter for shrub stumping. The circular saw blade and the cutter are simple in structure, cannot extrude shrub in a friction mode and enables a cut face to be smooth. The circular saw blade comprises a base body formed in a punching mode, the middle of the base body protrudes towards one side relative to an outer ring, a pit is formed in the middle of the other side, a through hole is formed in the center of the middle, and saw teeth are formed on the periphery of the outer ring. The circular saw blade is clamped tightly by a bolt and nut mechanism, the lower end of the bolt and nut mechanism located in the pit is higher than the cutting plane of the circular saw blade, and the threaded portion at the upper end of a bolt stretches out of a nut.
Description
Technical field
The cutterhead that present technique relates to saw blade and contains saw blade, especially relates to saw blade and cutterhead for a kind of shrub stubble flattening.
Background technology
At present, in western China, the stump of desert shrub is the indispensable link of growth.In order to guarantee germination rate after stump in the coming year, to its stump, will meet certain biological requirement, shrub section is smooth, the phenomenon such as can not tear, burn, and in cutting desert shrub process, the thickness of saw blade is less, and the section that cutting shrub generates is more smooth, but for larger-diameter saw blade, thickness is too small, integral rigidity will decline to some extent, and during cutting, saw blade easily produces deformation, even fracture.For this situation, generally adopt the method that increases platen diameter and thickness to make up, the thickness of saw blade reaches 5mm conventionally.And the outstanding platen of this class saw blade below can push and damage desert shrub section in traveling process, damages the growing point of shrub, be unfavorable for the growth in the coming year of shrub.Therefore be badly in need of a kind of simple in structure, stump saw blade that applicability is good.
Summary of the invention
The object of present technique is to overcome the deficiency that prior art exists, provide a kind of frivolous, simple in structure, to shrub, can not produce friction and Extrusion, shrub stubble flattening saw blade that cut surface is smooth.
Present technique is achieved through the following technical solutions:
Saw blade for this shrub stubble flattening, has by stamping forming matrix, and the middle part of matrix to one side-prominent, has formed pit at the middle part of opposite side with respect to outer ring, and the center at middle part has through hole, and the periphery of outer ring has sawtooth.
Above-mentioned shrub stubble flattening saw blade, is connected by the inclined-plane tilting between middle part and outer ring.
Above-mentioned shrub stubble flattening saw blade, matrix thickness is 1.5mm.
Present technique provide simultaneously a kind of simple in structure, to shrub, can not produce friction and Extrusion, shrub stubble flattening cutterhead that cut surface is smooth.
Cutterhead for this shrub stubble flattening, it comprises above-mentioned shrub stubble flattening saw blade, and described saw blade is clamped by bolt-nut mechanism, is positioned at the lower end of bolt-nut mechanism of pit higher than the cutting plane of saw blade, and nut is stretched out in the threaded portion of bolt upper end.
Above-mentioned shrub stubble flattening cutterhead, bolt-nut mechanism also comprises platen, pressing disc, and pressing disc is positioned at pit, and upper platen is positioned at the outstanding side of saw blade; Screw bolt passes pressing disc, through hole, upper platen also coordinate with nut and saw blade are clamped between upper pressing disc.
Above-mentioned shrub stubble flattening cutterhead, the lower end head of bolt embeds in the counterbore on pressing disc.
Above-mentioned shrub stubble flattening cutterhead, the threaded portion of bolt upper end with for driving the screw on the power take-off that bolt rotates to coordinate.
The beneficial effect of present technique: the shrub stubble flattening of present technique with saw blade when carrying out stump, the pressing disc and the bolt that are built in pit are connected to saw blade in rotating shaft, pressing disc and bolt bottom are higher than the cutting plane with saw blade, in traveling process, shrub section maintains certain distance with saw blade bottom surface all the time, thereby avoid section to cause unnecessary friction and extruding, make shrub cut off surfacing smooth, hair stubble is few, increase the next year germination rate of root, be applicable to the stump rejuvenation of all kinds of shrubs.By punch forming, form the saw blade with pit, the intensity of saw blade has also been played to booster action, prevent the shake of saw blade, so even if matrix thickness is 1.5mm, also can not damage.Meanwhile, thickness only has the saw blade of 1.5mm, and during cutting shrub, little to the otch damage of shrub, it is more smooth smooth that shrub is cut off surface.

Embodiment
Below in conjunction with accompanying drawing, present technique is described in detail.
The shrub stubble flattening of present technique is 1.5mm by saw blade 1 its matrix thickness, and by punch forming, the inner punch that adopts is clamp-oned, and in a side, forms round table-like pit, and pit periphery and saw blade plane have constant slope.
Whole cutterhead is comprised of saw blade 1, pressing disc 2, upper platen 3, bolt 4, nut 5, spring shim 6, backing plate 7 for shrub stubble flattening, in the middle of shrub stubble flattening is pressed in by pressing disc 2 and upper platen 3 with saw blade 1, by round orifices orientation, its combination is enclosed within on bolt 4, bolt 4 can be embedded in pressing disc 2, thereby both can not produce slip, on upper platen 3, add backing plate 7 and spring shim 6, finally nut 5 is spun on bolt 4, fastening nut 5 can compress whole cutter head structure.Shrub stubble flattening is first fixed by bolt 4 and nut 5 with saw blade 1, then the threaded portion stretching out by bolt 4 is directly connected on power take-off 8.Power take-off 8 drives bolt 4 rotations while rotating, the assembly connecting with bolt 4 also thereupon together with rotation, bolt 4 thread rotary orientations and power take-off 8 switched in opposite of wherein processing, to prevent getting loose of whole cutter head structure, pressing disc 2 is used the cutting plane of saw blade 1 with the bottom of bolt 4 higher than shrub stubble flattening, in traveling process, shrub 9 sections have certain distance with cutterhead bottom surface all the time like this, thereby avoid section to cause squeeze and destroy, damage the growing point of shrub, reduced the friction of saw blade and shrub section simultaneously, make it cut off surfacing smooth, hair stubble is few, increased the next year germination rate of root, be applicable to the stump rejuvenation of all kinds of shrubs.
