SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a sample sampling device for ice mechanics test, which realizes the rapid extraction of ice samples through the internal tension of the drill.

The object of the present invention is achieved in this way:

The present invention is a sample sampling device for ice mechanics test, which is characterized by comprising an elastic drill bit, a first helical structure, a second helical structure, a gasoline engine, a first helical structure and a second helical The top of the structure is connected to the two ends of the helical connection body respectively, the bottom of the first helical structure and the bottom of the second helical structure are respectively connected to the elastic drill bit, and the first and second helical structures are intertwined with each other. A double helix structure is formed, a rotating shaft is fixed above the screw connecting body, the rotating shaft is connected to the gasoline engine through the rotating shaft connecting piece, and handles are installed on both sides of the gasoline engine.

The present invention can also include:

1. Driven by the gasoline engine, the double helix structure drives the elastic drill bit through the ice layer, and the elastic drill bit loses the outward tension of the ice sample to the elastic drill bit, that is, the elastic drill bit tightens inward, so that the ice sample is pulled away from the ice surface .

The advantages of the invention are: the invention is practical and cost-saving, a gasoline engine with a gasoline tank can conduct field sampling on the ice surface, and the elastic drill bit can tighten and hold the lower part of the ice ocean after drilling through the ice surface to directly extract the ice sample.

FIG. 1 is a schematic structural diagram of the present invention.

Detailed ways

The present invention will be described in more detail below in conjunction with the accompanying drawings:

Referring to FIG. 1 , the elastic drill bit 1 is fixed directly below the helical structure 2 and the helical structure 3 , the helical structure 2 and the helical structure 3 are fixedly connected by the screw connecting rod 4 , and the rotating shaft 5 is fixed on the screw connecting rod 4 Above, the rotating shaft connecting piece 6 connects the rotating shaft 5 and the gasoline engine 10 , and is fixed by three bolts 7 . The handle 8 and the handle 9 are arranged and fixed on both sides of the gasoline engine 10, and the gasoline tank 11 is installed above the gasoline engine.

During the ice drilling process, first fix the elastic drill bit 1 at a specific position on the ice surface, and hold the handle 9 and the handle 8 with both hands to maintain the balance of the drilling rig. Turn on the switch of the gasoline engine 10, let the gasoline engine 10 drive the whole drilling rig to rotate, a large amount of ice chips will appear on the ice surface as the drill bit goes deeper, and the ice chips will be swept away. When the elastic drill bit 1 passes through the ice layer, lift the handle 9 and the handle 8 forcefully, and lift the whole drilling rig to escape from the ice layer, that is, the ice surface sampling is completed.

When the elastic drill bit 1 is immersed in the drilled ice layer, the elastic drill bit 1 loses the outward tension of the ice sample to the elastic drill bit 1 . That is, the elastic drill bit 1 is tightened inward to hold the lower body of the ice sample and pull the ice sample away from the ice surface.

The invention is a sample sampling device for ice mechanics test, which is mainly used in the technical field of ice surface sampling, and includes a gasoline engine 10 driving a rotating shaft to rotate, a double helix structure, a screw connecting rod 4, a bolt 7, and a rotating shaft connecting piece 6. Elastic drill bit 1, gasoline tank 11, handle 8,9. The device of the present invention connects the rotating shaft 5 and the gasoline engine 10 through the connecting piece of the rotating shaft 6, and is fixed by bolts 7. The gasoline engine 10 has symmetrical handles 8 and 9, which mainly play the role of maintaining the balance of the drilling rig. The elastic drill bit 1 mainly has internal tension, shrinks inward after drilling through the ice surface, and can quickly extract the ice sample without other components and devices. During the ice drilling process, first fix the drilling position for taking the ice sample, hold the handle tightly with both hands, turn on the gasoline engine 10, and the drilling rig starts to rotate. . In order to drill more efficiently, two people can hold the handle.
