The side of drill bit 2 is provided with longitudinal grooved (not shown), and the end of drill bit 2 is used as cutting native knife 9, as shown in figure 4, It is unicuspid shape, double pointed shape or zigzag to cut native knife 9;
The length of Novel earth drill is 0.5m~1.3m, the length of the second drilling rod 102 for whole geotome length 1/5~ 2/5, the length of drill bit 2 is the 1/5~1/3 of whole geotome length, and the external diameter of drill bit 2 is 38mm~70mm, the external diameter of drill bit 2 It is bigger 1mm~12mm than the external diameter of drilling rod 1.
Novel earth drill of the present utility model, in use, handle, drilling rod and drill bit are assembled together, insert perpendicular to the ground Enter soil soil sampling, because drilling rod includes the first drilling rod and the second drilling rod successively from top to bottom, between the first drilling rod and handle, Between one drilling rod and the second drilling rod, between the second drilling rod and drill bit be to be detachably connected, several sections can be splitted into, very Easily it is put into inside a collecting bag, is easy to carry and stores, and because the side of the second drilling rod is provided with strip open-work, the Bulldozing rod is provided with two drilling rods, the upper end of bulldozing rod is provided with the bulldozing rod handle stretched out from strip open-work, bulldozing rod Bottom is extend into drill bit, and the length of Novel earth drill is 0.5m~1.3m, and the length of the second drilling rod is whole geotome length 1/5~2/5, the length of drill bit is the 1/5~1/3 of whole geotome length, and the length of bulldozing rod of the present utility model is significantly Degree shortens, and resistance during soil-shifting will reduce, and bulldozing rod is arranged on the bottom of geotome, can be with trick simultaneously when soil-shifting With being easy to exert oneself, soil released, when particularly running into especially glutinous soil and push away motionless, advantage of the present utility model will Highlight, further, since the top of bulldozing rod is fixedly installed the orientation direction pipe being slidingly fitted with the second drilling rod, positioning Guiding tube can play a part of when bulldozing rod is bulldozed guiding and cross spacing, due to drill bit more slightly fetches earth resistance will It is bigger, and the external diameter of the utility model drill bit is only bigger 1mm~12mm than the external diameter of drilling rod, resistance when fetching earth will be much smaller, And the soil sample taken can also meet the needs of surveying soil now.
Further, it is detachably connected as:Screw thread is directly connected to;
Or connected by connector, the connector passes through screw thread with handle, the first drilling rod, the second drilling rod and drill bit Connection;
Or connected by connector, the connector passes through bearing pin with handle, the first drilling rod, the second drilling rod and drill bit Connection, it is specially:First two parts (such as the first drilling rod and the second drilling rod) are connected together, then consolidated with bearing pin through two parts It is fixed.
This detachable connection not only facilitates dismounting, and fastness is preferable after connection, does not influence user of service and takes Used when native.It should be appreciated that being detachably connected in addition to using above-mentioned connected mode, people in the art can also be used The connected mode that member is readily apparent that, does not influence the implementation of technical solutions of the utility model.
Preferably, soil-shifting piece 7 is circle, and the external diameter of soil-shifting piece 7 is smaller 1mm~12mm than the internal diameter of drill bit 2.It can so protect It is up and down in drill bit to demonstrate,prove soil-shifting piece, and and can ensures the soil sample in drill bit to be released with as far as possible few number when bulldozing. In addition, soil-shifting piece 7 is bolted with bulldozing rod 5.This fixed form not only ensure that fastness, and after going wrong Convenient maintenance.
For convenience by the completely out drill bit of soil sample, bulldozing rod 5 is identical with the length of drill bit 2.
Further, the side of strip open-work 4 is provided with scale on the second drilling rod 102.It can be controlled by scale Produce the depth that fetches earth of earth boring auger.
Preferably, orientation direction pipe 8 is plastic tube.Materials are not only facilitated using such a material, and wearability is preferable, makes Use long lifespan.
As a kind of improvement of the present utility model, as shown in figure 5, the end of the second drilling rod 102 can be provided with lug 10, Pedal 11 is hinged with lug 10.When fetching earth, pedal is laid flat, foot pedal, uses both hands and feet and fetches earth, is easily had an effect, soil is taken Out.
In the utility model, as shown in Fig. 2 longitudinal raised positive stop strip can be provided with the inwall of the second drilling rod 102 12, the fluting 13 being engaged with raised positive stop strip 12 is provided with orientation direction pipe 8.Raised positive stop strip and fluting are engaged, can Keep vertically moving to ensure bulldozing rod during soil-shifting, it is convenient that soil is released into drill bit.
Novel earth drill of the present utility model, generally there are 3 advantages:
1. it is easy to disassemble.Traditional geotome head is bigger, bad to tear open, drill bit can only be removed, and is not easy to store, And Novel borrowing equipment of the present utility model can split into several sections, it is very easy to be put into inside a collecting bag, is easy to carry;
2. second improvement is its bulldozing rod.The bulldozing rod of traditional geotome is especially long, and bulldozing rod is from handle Top is to following, and resistance ratios are larger during causing whole bulldoze up to 1 meter due to bulldozing rod, it is not easy to pushes away, in addition, bulldozing Bar is in that additional piece of upper handle portion, and inconvenience is held with hand, is not easy to exert oneself when soil-shifting, in general, two It is difficult to exert oneself that individual hand, which coordinates, and the length of the bulldozing rod of the utility model geotome is greatly shortened, and bulldozing rod only has more than ten public affairs 20 centimeters are assigned to, and is arranged on bottom, can be used both hands and feet, is easy to exert oneself, soil is released, is on the one hand because bar is short , resistance reduces, and is on the other hand because can use both hands and feet, easily has an effect, soil is released, and particularly runs into especially glutinous Soil when push away motionless, advantage of the present utility model will highlight;
3. the 3rd improvement is drill bit.The native knife of cutting of drill bit of the present utility model is double end, and it is not outward turning to cut native knife , the drill bit of the geotome of prior art is outward turning, because bore is bigger, resistance is very during whole cutting soil Greatly, that is, original drill bit, the external diameter of drill bit is more much greater than the external diameter for the earth boring auger that fetches earth, and the resistance that causes to fetch earth is big, in addition, this The external diameter of the whole drill bit of utility model is small, because the thicker resistance of drill bit can be bigger, the soil basis that very thick drill bit takes has more than is needed, So the utility model diminishes outside diameter, reduce resistance, accelerate the efficiency of cutting soil, while the soil taken tails off, and also can Meets the needs of surveying soil now.
Described above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art For personnel, on the premise of principle described in the utility model is not departed from, some improvements and modifications can also be made, these improvement The scope of protection of the utility model is also should be regarded as with retouching.
