Description

A sampler for geological exploration

technical field

The invention relates to a geological exploration tool, in particular to a geological exploration sampler.

Background technique

"Geology", also called geology, mainly studies the earth and its origin and evolution. Practical applications include: prediction of earthquakes, search and exploration of various minerals, disastrous landslides, and evolution of paleontology. Geological prospecting is the discovery of mineral deposits with industrial significance in the general survey of mineral resources. In order to ascertain the quality and quantity of mineral products, as well as the technical conditions for mining and utilization, provide mineral reserves and geological data required for mine construction design, and analyze rocks in a certain area. , formation, structure, minerals, hydrology, geomorphology and other geological conditions to conduct investigation and research work.

Exploration samplers in the prior art are usually complex in structure and cumbersome to operate. The soil to be sampled is generally lumpy. After sampling, it needs to be crushed and analyzed for soil quality. The steps are divided into several steps, which is very troublesome. Hard, which brings trouble to the sampling work.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a geological exploration sampler to solve the problem of inconvenient sampling of the existing soil sampler.

In order to realize the purpose of the present invention, the technical scheme adopted in the present invention is:

A sampler for geological exploration, comprising a cylinder, an end connected to one end thereof, and a push-pull rod arranged in the cylinder, protruding impact rims are provided at both ends of the cylinder, and surroundings of the cylinder are provided with Impact handle, the impact handle is a hollow body with thick ends and a thin middle, and there is a back and forth slide between the impact flanges. The end is provided with a drill bit, and the drill bit includes peripheral cutting knives and loose soil. Knife, described cutting knife is circular frustum ring and has opening on one side thereof, and described soil loosening knife is T-shaped vertical connection and is arranged on the end of cutting knife by two blades.

More preferably, the push-pull rod includes a rod body, a first piston and a second piston, the tail of the rod body is provided with a push-pull handle, and the head and the middle part of the rod body are respectively provided with an anti-loosening mechanism to prevent the first piston and the second piston from falling off. ring, the first piston and the second piston are sleeved on the anti-loosening ring and driven by the rod body to perform piston movement in the cylinder.

More preferably, the cylinder body is provided with a limiting protrusion preventing the piston from detaching.

More preferably, the end head is threaded and detachable connected with the barrel.

More preferably, the surface of the impact grip has an arc transition and the side edges of the impact grip are all round transition angles.

More preferably, a movable annular lampshade is further provided on the cylinder, and lamp beads are arranged on the annular lampshade.

Instructions:

When in use, the user holds the impact grip and uses the inertial impact on the impact convex edge, and the end is inserted into the soil to be sampled under force, and the cutting knife on the drill bit cuts and scratches the soil. The soil loosening knife is T-shaped. The soil is crushed, and the crushed soil enters the cylinder. At this time, the push-pull rod can be pulled up. Under the action of the first piston and the second piston, the sampled soil is more likely to enter the cylinder under the influence of the sealed negative pressure in the cylinder. Sampling Finally, push the push-pull rod to move and pour the sampled soil into the sampling and testing container for testing.

Beneficial effects of the present invention:

Compared with the existing soil sampling structure, the present invention adopts a drill bit structure in which a cutting knife cooperates with a loose soil knife, and uses a circular cutting knife to separate the sampled soil, and then uses a loose soil knife to separate the hard soil after cutting. Crushing, T-shaped soil loosening knife can have better crushing effect; the addition of impact convex edge and impact grip can realize the use of impact inertia to make the drill bit inserted deeper, which is convenient for sampling deep soil, and the design with side opening can facilitate the sampling after sampling. Topple over; in order to ensure that the hand will not be pinched during a strong impact, the shape of the impact grip is designed to be thick at both ends and a thin arc in the middle, and the edges are rounded for transition, so that the thicker thickness on both sides can protect the edges of fingers when holding Stay away from the contact point of the impact convex edge to avoid pinching. The first piston on the push-pull rod mainly plays the role of pushing and pulling, while the role of the second piston is to ensure the sealing of the inner part of the cylinder on the one hand, and to ensure the stability during the push-pull process on the other hand. , will not cause shaking, and the structure of the end can be disassembled and replaced, which is very convenient.
