Description

Sampling drill bit for soil detection

Technical Field

The utility model relates to an environmental protection detects sampling equipment, specifically is a soil testing is with sample drill bit.

Background

When detecting soil, need first take a sample to soil. When taking a sample to soil, when taking a sample to surface soil, adopt the mode such as manpower excavation can solve, the manual work excavates soil to the soil layer of suitable degree of depth, again take a sample to soil can. When deep soil is sampled, a manual digging mode is not suitable, and a large amount of manpower is consumed, so that a special drilling machine is generally used for drilling and sampling. Among the prior art, have and set up the flight bottom the drill bit, during the flight was deepened along with the drill bit rotation and is gone deep into the soil layer when the drill bit was dark, and during the motor reversal, when the drill bit took out in the soil layer, can hold some soil in the flight, realized the sample operation to deep soil. However, the operation inevitably carries soil samples of different depths, and the detection result is not accurate enough. Some of the soil sampling devices are used for sampling by penetrating the sampler into the soil layer after the drill bit is used for drilling, and the sampling mode is also inaccurate because the soil at the top can be inclined downwards after the drill bit is used for drilling, and the soil falling to the bottom of the soil layer is not completely the soil at the position, so that the sampling result can be influenced.

Disclosure of Invention

An object of the utility model is to overcome not enough among the prior art, provide a soil testing is with sample drill bit, this kind of sample drill bit can protect the soil at top can not fall into the bottom, guarantees the accuracy of sample result.

For solving the prior art problem, the utility model discloses a soil testing is with sample drill bit, including the motor, be provided with the drilling rod below the motor, the outside of drilling rod is provided with solid fixed cylinder, through threaded connection between solid fixed cylinder and the drilling rod, be provided with in the drilling rod bottom and bore the tooth, it is the toper spine structure to bore the tooth, the bottom of solid fixed cylinder is sharp toper structure, the brill tooth position of drilling rod is located beyond the end of solid fixed cylinder.

Preferably, the top of the drill rod is provided with threads, the top of the fixed cylinder is provided with threads, and the top of the drill rod is matched with the threads on the top of the fixed cylinder.

Preferably, the ends of the drill teeth at the bottom of the drill rod are all located inside the fixed cylinder.

Preferably, only the tooth part at the bottom of the drill rod is exposed outside the fixed cylinder.

Preferably, a graduated scale is arranged outside the fixed cylinder.

Preferably, a fixing hole is formed at the outer side of the top of the fixing cylinder.

The utility model discloses a use lies in: the drilling rod and the fixed cylinder are stably connected, when the motor rotates forwards, the drilling rod and the fixed cylinder are tightly connected through threads, a sampling position is selected, the drilling rod is made to penetrate into the bottom, and the penetration depth of the drilling rod is determined according to scale marks outside the fixed cylinder. When the drill rod enters a proper depth, the motor rotates reversely to separate the connection between the drill rod and the fixed cylinder, the drill rod is taken out of the fixed cylinder, and the fixed cylinder is kept in the soil layer. The existence of fixed cylinder forms a safety cover in the soil horizon to needing the sampling, can only sample the soil of fixed cylinder bottom, and the soil that does not have the top falls. The tool that utilizes the sampling is taken a sample at the stationary cylinder bottom, and after the sample was accomplished, deepened the drilling rod again and made both zonulae occludens in the stationary cylinder, pulled out ground with the stationary cylinder. The traction rope can be bound by the fixing hole at the top of the fixing barrel, and the fixing barrel can be pulled out of the ground.

The beneficial effects of the utility model reside in that: 1. the measurement is accurate. The fixed cylinder is arranged outside the drill rod, the fixed cylinder forms a protective cover on the outer side of the sampling soil layer, and the accuracy of soil needing to be sampled is guaranteed. 2. The sampling is convenient. The drilling teeth are arranged at the bottom of the drill rod and can be cut into loose soil particles for a conical pointed structure, the drill rod can be taken out, a tool for taking samples can be conveniently used for sampling, and the problem of difficulty in sampling caused by the fact that the soil layer is hard is avoided.

Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

The utility model provides a soil testing is with sample drill bit, includes motor 1, is provided with drilling rod 2 below motor 1, the outside of drilling rod 2 is provided with solid fixed cylinder 3, through threaded connection between solid fixed cylinder 3 and the drilling rod 2, be provided with in 2 bottoms of drilling rod and bore tooth 4, it is the toper spine structure to bore tooth 4, the bottom of solid fixed cylinder 3 is sharp conical structure, the boring tooth 4 position of drilling rod 2 is located beyond the end of solid fixed cylinder 3.

The top of the drill rod 2 is provided with threads, the top of the fixed cylinder 3 is provided with threads, the top of the drill rod 2 is matched with the threads at the top of the fixed cylinder 3, and the tail ends of the drill teeth 4 at the bottom of the drill rod 2 are located on the inner side of the fixed cylinder 3.

Only the drilling teeth 4 at the bottom of the drill rod 2 are exposed outside the fixed cylinder 3, a graduated scale 5 is arranged outside the fixed cylinder 3, and a fixed hole 6 is arranged outside the top of the fixed cylinder 3.
