Description
Technical field
The utility model belongs to technical field of garden, specifically a kind of blade on lawn punching-machine.
Background technology
Garden lawn is trampled and the factor such as naturally to harden due to people and animals', and the loose degree of the soil on lawn can be made to reduce, and the oxygen content in soil also there will be deficiency, affects the normal growth of turf.Thus the lawn punching-machine of specialty can be used to carry out punching nursing to place such as the golf course that turf quality has higher requirements.Owing to nursing costly, thus the lawn of general family can not get the nursing of this patent due to the reason of expense.
The perforating cutting tool of existing lawn punching-machine is generally adopt many perforating needles to combine, each perforating needle needs carry out professional installation and fix, assembling costly, and perforating needle is generally process with steel pipe, professional equipment need be used to process, production process is many, complex process, and cost is high, uses limitation large.
Through looking into the Chinese patent " a kind of portable lawn punching-machine " that the existing patent No. is CN201410211471.7, it is characterized in that, the weightening finish case comprising upper shed and the fixed support be fixed on described weightening finish case four angles, described fixed support comprises multiple dismountable dead lever linked together, described fixed support upper edge is provided with handle, upper shed place of described weightening finish case is provided with the cover plate that can cover its upper shed, described cover plate is fixed in the upper shed of described weightening finish case by buckle, the base plate of described weightening finish case is provided with multiple through hole, described baseplate underside is provided with multiple dismountable punching nail be arranged in through hole, described punching nail is inner be provided with hollow run through its upper and lower passage.This puncher small volume, use more convenient, but need to arrange multiple punching nail, make and process also more complicated, and except punching with sow, the limitation of use is larger.
Utility model content
First technical problem to be solved in the utility model be to provide a kind of simple and reasonable, blade easy to process is installed, can be used for lawn punching, and cost is lower.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of blade, it is characterized in that: described blade comprises a knife plate, knife plate is provided with central shaft hole, the one-body molded perforating needle having several hoop to distribute in the outward flange side of knife plate, the front portion of perforating needle is the tubular structure of hollow, be provided with cutting edge at the head of tubular structure, the inner end of the postmedian of perforating needle is connected with the outward flange of knife plate, and outer end is bent to form the tile shape structure that cross section is circular arc.
As improvement, the front portion of described perforating needle is the tubular structure that head diameter is little, tail diameter large, cone angle is 1 ~ 4 °.
As improvement, described knife plate and perforating needle are employing steel plate puncheds, roll into one-body molded.
Preferably, the inner end of the postmedian of described perforating needle and the outward flange of knife plate are tangent settings.
Preferred again, described perforating needle is equally distributed 3 ~ 4, and the length of the front tubular structure of perforating needle is 25 ~ 35mm.
As improvement, described knife plate adopts the knife plate structure of fan blade shape.
Compared with prior art, the utility model has the advantage of: blade be adopt steel plate punched, roll one-body molded, the front portion of perforating needle is in the tubular structure with tapering, be beneficial to the discharge of earth, head is provided with cutting edge, be convenient to alleviate the pressure in incision soil, the postmedian of perforating needle is tile shape, makes the earth of deriving from perforating needle head can discharge timely and not produce the blocking of heap sum.Blade structure advantages of simple of the present utility model, make easy to process, can be arranged on loosenning tiller and punch, greatly save material and installation procedure, cost is lower.

Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Figure 1, the blade of the present embodiment, comprise a knife plate 1, knife plate 1 for being provided with the wind foliation structure of central shaft hole 11, the one-body molded perforating needle 2 having several hoop to distribute in the outward flange side of knife plate 1, the front portion of perforating needle 2 is that head diameter is little, tail diameter large, has the tubular structure 22 of certain taper, cone angle is 1 ~ 4 °, and this structure can be beneficial to earth and discharge, and is provided with cutting edge 21 at the head of tubular structure 22, incision earth can be beneficial to, alleviate the pressure of punching; The inner end of the postmedian of perforating needle 2 is connected with the outward flange of knife plate 1, preferably tangent setting, outer end is bent to form the tile shape structure 23 that cross section is circular arc, preferably semi-circular shape, the earth of deriving from perforating needle 2 head can be discharged timely and do not produce the blocking of heap sum, and the afterbody of perforating needle 2 be provided with one curve backward be convenient to the earth posteriorly inclination angle D that discharges of direction, perforating needle 23 of distributing for uniform intervals, the length of the front tubular structure of perforating needle 2 is 30mm.
During manufacture, first adopt steel plate stamping to be pressed into knife plate 1 structure of the fan blade shape with central shaft hole 11 as Fig. 2, and on three of knife plate 1 outstanding edges the one-body molded side direction T-shaped structure had for making perforating needle 2; Then put the first edge on a knife or a pair of scissors the head of side direction T-shaped structure mouth 21 (as Fig. 3), finally side direction T-shaped structure is carried out rolling and make perforating needle 2 (as Fig. 4), its middle front part rolls into the tubular structure 22 with certain taper of hollow, the length of tubular structure is 25 ~ 35mm, postmedian rolls into the tile shape structure 23 that cross section is circular arc, preferably semi-circular shape, the afterbody of tile shape structure 23 is provided with an inclination angle D curved backward.
Realize the integrated of perforating needle 2 and knife plate 1 by above-mentioned steps, greatly save material and installation procedure, cost advantage is obvious.
During work, blade of the present utility model is arranged on the blade that loosens the soil on loosenning tiller with original and carries out exchange and just can punch, and install easily, there is very strong Practical Performance.
