Abstract
The utility model discloses a soil sampling drill. The soil sampling drill comprises a connecting rod, a connecting column and a sampling drill bit, wherein the connecting rod is used for cooperating with a drill clamp; the connecting column is connected with the connecting rod and a sampler barrel; the sampler barrel of the soil sampling drill is in a hollow barrel structure; the drill bit is fixedly arranged on the end of the sampler barrel in the barrel structure; and a grooved soil extraction groove is formed in the side wall of the sampler barrel along the axial direction of the sampler barrel. The soil sampling drill has the advantages of simple structure and low manufacture cost; and additionally, sampling is precise, convenient and labor-saving, and the working efficiency of manual sampling can be improved greatly.
Description
Technical field
The utility model relates to the instrument of soil sample of the instrument, particularly a kind of tubular of the sampling of a kind of agricultural land soil.
Background technology
The collection of existing field soil sample, still artificial mechanism sampling basically, employed instrument is Luoyang Spade for example.Adopt this class sampling instrument fetch earth operation both useless power and sample time long, labour intensity is big.Therefore and be not suitable for the collection of field soil sample present stage is special-purpose electronic sampling instrument also, but this class instrument manufacturing cost is bigger, and needs special-purpose power source.
Summary of the invention
The utility model is a kind of soil sample instrument that overcomes the prior art deficiency.
The utility model comprises: for the connecting rod that cooperates with drill jig, the joint pin that connecting rod is connected with sampler barrel, and chisel bit, sampler barrel of the present utility model is the tubular structure of hollow, fixedly there is drill bit the end of the sampler barrel of tubular structure, and does not axially offer a groove that fetches earth that is flute profile along sampler barrel on the sidewall of sampler barrel.
The end fixed reamer head of the tubular structure of a kind of soil sample drill bit of the present utility model is zigzag drill bit.
A kind of soil sample drill bit of the present utility model is provided with graduated scale vertically on the outer wall of its sampler barrel.
The described rig that is used with instrument of the present utility model refers to percussion drill or the power drill that present stage is common.In use, the drill jig of connecting rod of the present utility model with percussion drill or power drill can be cooperated, the utility model is fixed on the drill jig of percussion drill or power drill, with the power of percussion drill or the power drill power as the sampling operation, make the bit drills underground layer inside of the sampler barrel end that is positioned at tubular structure by the rotation of percussion drill or power drill, carry out soil sample, and make the soil sample of getting remain in sampler barrel inside.Can utilize the graduated scale that arranges on its sampler barrel sidewall to determine the degree of depth of sampling in this course.After taking out soil sample, can along the groove of axially offering that fetches earth that is flute profile of sampler barrel soil sample not taken out in sampler barrel by the sidewall of sampler barrel.
The utlity model has simple in structure, low cost of manufacture, sampling is accurate, convenient, laborsaving, can improve the advantage of the operating efficiency of manual sampling greatly.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model, schematic diagram when accompanying drawing 2 is use, among the figure: 1-is positioned at the jagged bit of sampler barrel end, for the connecting rod 2 that cooperates with drill jig, the joint pin 3 that is connected with sampler barrel 4 with connecting rod 2, the 4-sampler barrel, the groove of axially offering that fetches earth that is flute profile along sampler barrel that 5-sampler barrel sidewall is outer.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described.
As seen from Figure 1, the utility model by the indention drill bit 1 that is positioned at the sampler barrel end, be used for and connecting rod, the joint pin that the 3-connecting rod is connected with sampler barrel, the sampler barrel 4 of the tubular structure of hollow, the outer groove of axially offering 5 that fetches earth that is flute profile along sampler barrel of sampler barrel sidewall constitutes.As seen from Figure 1, drill bit of the present utility model is zigzag drill bit.In actual use as shown in Figure 2, the utility model directly is fixed on the drill jig with the merging that matches of the drill jig of percussion drill.In addition the sidewall outer of sampler barrel 4 sampler barrel axially also can be provided with graduated scale (this point in the accompanying drawings expression), when fetching earth operation, can grasp the degree of depth of sampling so easily.
The utility model makes the sawtooth drill bit contact with ground in use, in boring procedure, should vertically remain on the sawtooth drill bit underground, both hands are held percussion drill and are firmly pressed down the brill tube is rotated under the drive of percussion drill during sampling, the impact that utilizes percussion drill and rotation are buried the smooth auger of drill bit in the soil, the soil sample that is removed in the drill bit straight line moves downward enters in the tubular hollow structure of sampler barrel, it can be taken out get the deep soil sample reaching after, the groove 5 that fetches earth that arranges on the recycling sampler barrel takes out the dress box with soil sample.
Claims (3)
1. soil sample drill bit, comprise: for the connecting rod that cooperates with drill jig, the joint pin that connecting rod is connected with sampler barrel, and chisel bit, it is characterized in that sampler barrel is the tubular structure of hollow, fixedly there is drill bit the end of the sampler barrel of tubular structure, and the sidewall upper edge sampler barrel of sampler barrel axially offer a groove that fetches earth that is flute profile.
2. a kind of soil sample drill bit according to claim 1, the end fixed reamer head that it is characterized in that tubular structure is zigzag drill bit.
3. a kind of soil sample drill bit according to claim 1 and 2 is characterized in that being provided with graduated scale vertically on the outer wall of sampler barrel.
