Abstract
The utility model discloses a drill bit for drilling of tree injection nutrient solution, this drill bit include that from the top down connects gradually drillstock and spiral bit, spiral bit comprises fore -end and back tip connection, the front end of fore -end is provided with the cutting edge, back tip is provided with the cutting edge with the fore -end junction, the diameter of fore -end is lighter than the diameter of back tip. The utility model discloses can be used for using for tree injection nutrient solution, insecticide, germicide, growth regulation agent drilling, use the back with the syringe cooperation, no longer hurt the trees cortex, not have a strict requirement to the concentration of liquid medicine, it is with low costs, the practicality strong, convenient to use, the large tracts of land of being convenient for popularization.
Description
Technical field
The utility model belongs to agricultural equipment technical field, is specifically related to a kind of drill bit for the boring of tree injection nutrient solution.
Background technology
Conventional bit is generally cylindrical, bit diameter specification, and the hole got out also is cylindrical cavity, and when syringe etc. is inserted boring, can not effectively stop high concentration nutritional liquid to flow to cortex, this is the ubiquitous difficult problem of current tree injection high concentration nutritional liquid.
Utility model content
In view of this, main purpose of the present utility model is to provide a kind of drill bit for the boring of tree injection nutrient solution.
For achieving the above object, the technical solution of the utility model is achieved in that
The utility model embodiment provides a kind of drill bit for the boring of tree injection nutrient solution, this drill bit comprises and connects drillstock and spiral bit successively from top to bottom, described spiral bit is connected and composed by fore-end and rear end part, the front end of described fore-end is provided with blade, and described rear end part and fore-end junction are provided with blade; The diameter of described fore-end is less than the diameter of rear end part.
In such scheme, the angle of described blade is 100 degree.
In such scheme, described spiral bit is staged.
Compared with prior art, the beneficial effects of the utility model:
The utility model can be used in using to tree injection nutrient solution, insecticide, bactericide, growth regulator boring, with syringe with the use of rear, no longer injure trees cortex, strict requirement is not had to the concentration of liquid, cost is low, practical, easy to use, is convenient to spread.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 aperture schematic diagram that to be the utility model formed after boring on tree bar and and syringe with the use of schematic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model embodiment provides a kind of drill bit for the boring of tree injection nutrient solution, as shown in Figure 1, 2, this drill bit comprises and connects drillstock 5 and spiral bit 4 successively from top to bottom, described spiral bit 4 is connected and composed by fore-end 2 and rear end part 3, the front end of described fore-end 2 is provided with blade 1, and described rear end part 3 is provided with blade 1 with fore-end 2 junction; The diameter of described fore-end 2 is less than the diameter of rear end part, the hole of getting out like this, the inside cavity diameter is little, outermost cavity diameter is large, due to syringe front end can and the inside minor diameter cavity in extrusion process, form the form that closely cooperates, nutrient solution can be sealed in the little xylem of innermost diameter, and nutrient solution woodenly can only to transport up and down along innermost, not outwardly, not burn bark; Further, 3 centimeter length regional diameters of described chisel edge part 2 are less, and 2 centimeter length regional diameters of rear end part 3 are larger.
The angle of described blade 1 is 100 degree.
Described spiral bit 4 is staged, coordinates with tree nutrition syringe, in the xylem that high concentration nutritional liquid can be stoped aperture inside little, can not flow to the xylem that aperture, outside is large, more can not flow to cortex.
As shown in Figure 2, the course of work of the present utility model:
During use, first clamp drillstock 5 with electric hand drill, guarantee drill bit and tree bar in angle of 45 degrees, and drill bit is holed downwards, when drill bit rear end part 3 screw thread all enters tree bar xylem, exit drill bit, boring wood chip is cleaned out, then antibacterial for oily paste is spread upon uniformly in tree injector spring-like bottleneck annulus groove, smear and want smooth had better not interspacing, liquid reservoir body is pinched subsequently with hand, fertilizer releasing core head is inserted boring, by straight body, slightly firmly push inward, and push away motionless till, finally above liquid reservoir rear end, prick an air-vent, after injection in 6-24 hour terminates, pull out liquid reservoir and fertilizer releasing core, seal with boring sealing plug.
The utility model is compared with existing method, and its outstanding feature is:
1, simple and practical, boring meets tree bar injection requirement.
2, prevent high concentration nutritional liquid very efficiently outwardly in injection process, no longer injure bark.
The above, be only preferred embodiment of the present utility model, is not intended to limit protection domain of the present utility model.
