Abstract
The utility model provides a combined-type circular saw blade for shrub stumping, which is simple in structure and convenient to dismount, causes no friction and extrusion to a shrub and ensures a smooth cut surface. The combined-type circular saw blade for shrub stumping comprises a circular ring-shaped saw blade and a stepped disc with the middle part higher than the outer ring, wherein the circular ring-shaped saw blade is fixedly connected with the lower end surface of the outer ring of the stepped disc through countersunk head screws; the countersunk head screws are not exposed out of the lower end surface of the circular ring-shaped saw blade.
Description
Technical field
The utility model belongs to saw blade technical field, especially relates to a kind of combined type shrub stubble flattening saw blade.
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, but the outstanding platen of this class saw blade below can push and damage desert shrub section in traveling process, damage 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 purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of simple in structure, convenient disassembly is provided, and to shrub, can not produce friction and Extrusion, combined type shrub stubble flattening saw blade that cut surface is smooth.
The utility model is achieved through the following technical solutions:
This combined type shrub stubble flattening saw blade, comprises that annulus saw blade and middle part are higher than the trapezoidal dish of outer ring, and annulus saw blade adopts sunk screw to be fixed on the lower surface of trapezoidal dish outer ring, and sunk screw does not expose the lower surface of annulus saw blade.
Above-mentioned combined type shrub stubble flattening saw blade, has on the lower surface of trapezoidal dish outer ring that outstanding the periphery of locating ring contacts with the endoporus of annulus saw blade for the locating ring to annulus saw blade location, and the height of locating ring is not higher than the thickness of annulus saw blade.
Above-mentioned combined type shrub stubble flattening saw blade, trapezoidal dish middle part has the through hole that has keyway.
Above-mentioned combined type shrub stubble flattening saw blade, the sawtooth tooth depth in annulus saw blade periphery is 5mm, totally 160 teeth.
Above-mentioned combined type shrub stubble flattening saw blade, trapezoidal dish has two steps.
Beneficial effect: Combined type circular saw blade disclosed in the utility model only has the annulus saw blade of peripheral annular part for cutting, the bulk deformation producing in the time of can alleviating sawing, improve service life, both having made sawtooth tooth depth is that 5mm still can guarantee its intensity, also can not damage.Meanwhile, the sawtooth sheet that tooth depth is 5mm, during cutting shrub, very little to the otch damage of shrub, it is more smooth smooth that shrub is cut off surface.In addition, saw blade is when carrying out stump, in traveling process, shrub section maintains certain distance with combination 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, has increased the next year germination rate of root, is applicable to the stump rejuvenation of all kinds of shrubs.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Combined type shrub stubble flattening of the present utility model comprises annulus saw blade 1 with saw blade, and the periphery of annulus saw blade offers tiny sawtooth, and tooth depth is 5mm, whole 160 teeth, and material toggling amount is 0.3mm.On annulus saw blade, offer the inclined hole with tapering that 12 places distribute along even circumferential.Annulus saw blade adopts sunk screw 5 to be fixed on trapezoidal dish 2 by nut 3 and pad 4, and the inclined hole tapering on annulus saw blade 1 equates with sunk screw 5 head angle, and sunk screw 5 heads can embed in inclined hole.Trapezoidal dish 2 lower ends are provided with locating ring, and locating ring height is less than the thickness of saw blade, and trapezoidal dish 2 bossing middle parts, upper end have the through hole that has keyway.
Combined type shrub stubble flattening is enclosed within on power take-off 6 by sleeve 7 with saw blade, and bottom installs backing plate 9 additional, adopts spring shim 8 and bolt 10 that whole saw blade and power take-off 6 are tightened up.Location due to key when power take-off 6 rotates drives whole saw blade rotation, thread rotary orientation and the saw blade switched in opposite of wherein on power take-off 8, processing, to prevent getting loose of whole Combined sawblade structure, the bottom of whole Combined sawblade is higher than the cutting plane of shrub 11, in traveling process, shrub 11 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.
