Description
Technical field
The utility model relates to planting apparatus field, particularly relates to a kind of tree planting loosenning tiller rectangular blade drill bit.
Background technology
Near building, frequent needs are afforested, not only the environmental quality simultaneously substantially increasing people's life attractive in appearance, also plays the effect purified air, but often has the building waste of the stone much stayed when building in soil near building, have a strong impact on growth and the survival of plant, people adopt loosenning tiller to rectify and improve usually, but the drill bit of common loosenning tiller is screw blade, and intensity is less, stone cannot be smashed, drill bit easily damages.
Summary of the invention
The utility model for prior art above shortcomings, the tree planting loosenning tiller rectangular blade drill bit providing a kind of sound construction, intensity high.
The purpose of this utility model is achieved through the following technical solutions:
A kind of tree planting loosenning tiller rectangular blade drill bit, comprise tricorn bit, drillstock, rectangular blade, the long 100mm of described rectangular blade, wide 60mm, high 16mm, described rectangular blade leading flank has front cutting edge, described front cutting edge and rectangular blade bottom surface are 50 ° of angles, described rectangular blade right flank has right blade, described rectangular blade left surface has left connection half slot, the radius of described left connection half slot is 30mm, described left connection half slot connects drillstock, described left connection half slot wraps drillstock, described rectangular blade oblique weld is on drillstock, described rectangular blade cross section is parallelogram, described rectangular blade comprises rectangular blade, middle rectangular blade, lower rectangular blade, described upper rectangular blade, middle rectangular blade, lower rectangular blade is spiral to be evenly distributed on drillstock, described upper rectangular blade, middle rectangular blade, between lower rectangular blade three, there is identical difference in height.
Described drillstock inside has drill bit connecting hole, and described drill bit connecting hole diameter is 40mm, and described drill bit connecting hole top has screwed hole, the long 100mm of described screwed hole, and described drill bit connecting hole bottom connects joint pin.
Described joint pin height 80mm, diameter 40mm, described joint pin inserts drill bit connecting hole, described drill bit connecting hole and joint pin interference fits, described joint pin connects tricorn bit, the wide 80mm of described tricorn bit, described tricorn bit height 110mm, described tricorn bit drift angle is 40 °
Beneficial effect:
Rectangular blade oblique weld is on drillstock, described rectangular blade cross section is parallelogram, upper rectangular blade, middle rectangular blade, lower rectangular blade are spiral to be evenly distributed on drillstock, has identical difference in height between described upper rectangular blade, middle rectangular blade, lower rectangular blade three.In rotary course, due to the mode that this difference in height and rectangular blade tilt to install, the stone in soil and foreign material are made to be translated into above soil smoothly, for the soil near building, because its inside has more, larger rubble, affect vegetation growth, and this rectangular blade is thicker, intensity is large.Be better than common drill bit for this building soil effect of carrying out loosening the soil, rectangular blade is under the effect of left connection half slot simultaneously, and parcel is welded on drillstock, and sound construction, intensity is high.Described drillstock inside has drill bit connecting hole, described drill bit connecting hole bottom connects joint pin, described joint pin inserts drill bit connecting hole, described drill bit connecting hole and joint pin interference fits, the drill bit of tree planting loosenning tiller rectangular blade drill bit contrast other types, make simple, cost is low, tricorn bit and drillstock adopt modular construction simultaneously, be convenient to repair and replacement tricorn bit, and according to the planting requirement of different plant, the rectangular blade of different model can be selected, strong adaptability, improve tree planting loosenning tiller rectangular blade drilling life of bit and efficiency, be highly suitable for the more building yard of stone to use.
Accompanying drawing explanation
Fig. 1 is the utility model drillstock and rectangular blade counter structure schematic diagram.
Fig. 2 is rectangular blade counter structure schematic diagram described in the utility model.
Embodiment
According to drawings and embodiments the utility model is described in further detail below:
A kind of tree planting loosenning tiller rectangular blade drill bit, comprise tricorn bit 1, drillstock 2, rectangular blade 3, the long 100mm of described rectangular blade 3, wide 60mm, high 16mm, described rectangular blade 3 leading flank has front cutting edge 4, described front cutting edge and rectangular blade bottom surface are 50 ° of angles, described rectangular blade 3 right flank has right blade 5, described rectangular blade 3 left surface has left connection half slot 6, the radius of described left connection half slot 6 is 30mm, described left connection half slot 6 connects drillstock 2, described left connection half slot wraps drillstock, described rectangular blade oblique weld is on drillstock, described rectangular blade cross section is parallelogram, described rectangular blade 3 comprises rectangular blade, middle rectangular blade, lower rectangular blade, described upper rectangular blade, middle rectangular blade, lower rectangular blade is spiral to be evenly distributed on drillstock 2, described upper rectangular blade, middle rectangular blade, between lower rectangular blade three, there is identical difference in height.In rotary course, due to the mode that this difference in height and rectangular blade tilt to install, the stone in soil and foreign material are made to be translated into above soil smoothly, for the soil near building, because its inside has more, larger rubble, affect vegetation growth, and this rectangular blade is thicker, intensity is large.Be better than common drill bit for this building soil effect of carrying out loosening the soil, rectangular blade is under the effect of left connection half slot simultaneously, and parcel is welded on drillstock, and sound construction, intensity is high.
Described drillstock 2 inside has drill bit connecting hole 7, and described drill bit connecting hole 7 diameter is 40mm, and described drill bit connecting hole 7 top has screwed hole 8, the long 100mm of described screwed hole 8, and described drill bit connecting hole 7 bottom connects joint pin 9.
The high 80mm of described joint pin 9, diameter 40mm, described joint pin 9 inserts drill bit connecting hole 7, described drill bit connecting hole 7 and joint pin 9 interference fits, described joint pin 9 connects tricorn bit 1, the wide 80mm of described tricorn bit 1, the high 110mm of described tricorn bit 1, described tricorn bit 1 drift angle is 40 °.The drill bit of tree planting loosenning tiller rectangular blade drill bit contrast other types, make simple, cost is low, simultaneously tricorn bit and drillstock adopt modular construction, are convenient to repair and replacement tricorn bit, and according to the planting requirement of different plant, the rectangular blade of different model can be selected, strong adaptability, improves tree planting loosenning tiller rectangular blade drilling life of bit and efficiency, is highly suitable for the more building yard of stone and uses.
