Abstract
The utility model discloses a drill bit of underground biomass sampling hand drill, basic appearance is cylindric, and its lower edge is two oblique upright cutting edges, and the cutting edge is 30 ~ 60 with horizontal contained angle, and the drum more than its cutting edge is the sampler, and drill bit upper portion is connected with the drilling rod, and the drill bit of this kind of structure has the swift convenience of sampling, can keep earth pillar structure, and the sample is laborsaving easily, advantage with low costs. Degree
Description
The utility model belongs to a kind of improvement of underground biomass sampling gimlet bit.
The drill bit of present known underground biomass sampling hand drill has two kinds, and a kind of is the drill bit of Dutch type root system hand drill, and external form is cylindric, and the tube lower edge is a zigzag.The shortcoming of this drill bit is that the zigzag lower edge causes the sampling resistance to increase, sampling earth pillar volume out of true, and the earth pillar structure is destroyed, and the soil sample in the tube is difficult for taking out, and is unsuitable for studying the phreatophyte underground biomass.The steel cylinder that the drill bit of another hand drill is made up of two semicircular cylinders is nested together with becket, can separate each other, shortcoming is that sampling depth seldom surpasses 50cm, must rely on machinery to be pressed into, and causes the sampling cost excessive, rely on manpower then very to require great effort, so often do not adopted.
The purpose of this utility model is to provide a kind of can accelerate sample rate, keeps the earth pillar structure simultaneously, and it is convenient and strength-saving to take a sample, and is suitable for the gimlet bit of various soils condition sampling.
Technical characterictic of the present utility model is: the basic external form of drill bit is cylindric, and its lower edge is two tiltedly upright blades, and blade and horizontal sextant angle are 30 °～60 °; The above cylinder of blade is a sampler, and the groove of oriented under shed makes soil sample be convenient to therefrom take out between two blades of sampler one side; Drill bit top is connected with drilling rod.
It is efficient and convenient to the utlity model has sampling, and can keep the earth pillar structure, the advantage laborsaving easily, that cost is low of taking a sample.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model,
As shown in Figure 1, the basic external form of drill bit is cylindric, and its lower edge is two tiltedly upright blades 1, and blade 1 is 30 °～60 ° with horizontal sextant angle, and the above cylinder of blade is a sampler 2, the groove 3 of oriented under shed between two blades 1 of one side; The top of drill bit couples together by screw 4 and drilling rod 5.
When actual samples, firmly drilling rod is depressed in rotation, and drill bit is pressed in the soil, the lower edge of drill bit is two tiltedly upright blades, be very beneficial for moving downward, taking a sample of drill bit, after drill bit cut down earth pillar certain volume, that have root system of plant, earth pillar just entered in the sampler at drill bit middle part.Extract drill bit then, by the groove of sampler one side, just the soil sample that has root system of plant can be taken out, in general, knife edge included angle is little, be suitable for drilling through hard soil property, and angle is suitable for drilling through soft soil property greatly.
