Description
Technical Field
The invention relates to a sampling device, in particular to an ice sample sampling device.
Background
Currently, ice surface sampling generally uses a drilling machine to extract an ice sample, and for example, an ice sampling drill of application No. 201610793788.5 and an ice sampling method implemented by using the drill have a cylindrical structure, so that the structure cost is high, and other components are required to extract the ice sample in the process of extracting the ice sample.
Disclosure of Invention
The invention aims to provide a test piece sampling device for an ice mechanical test, which realizes the quick extraction of an ice sample through the internal tension of a drill bit.
The purpose of the invention is realized as follows:
the invention relates to a test piece sampling device for an ice mechanical test, which is characterized in that: including the elastic drill bit, first helix structure, second helix structure, the gasoline engine, two tip of spiral connector are connected respectively at the top of first helix structure and second helix structure, the elastic drill bit is connected respectively to the bottom of first helix structure and second helix structure, first helix structure and second helix structure interweave mutually and constitute two helix structures, spiral connector top is fixed with the pivot, the gasoline engine is connected through the pivot connecting piece in the pivot, the hand (hold) is all installed to the both sides of gasoline engine.
The present invention may further comprise:
1. under the drive of the gasoline engine, the elastic drill bit is driven by the double helix structure body to pass through the ice layer, the elastic drill bit loses the outward tension of the ice sample on the elastic drill bit, namely the elastic drill bit is tightened inwards, and the ice sample is pulled away from the ice surface.
The invention has the advantages that: the invention is practical and saves cost, the gasoline engine with the gasoline tank can carry out on-site sampling on the ice surface, and the elastic drill bit can tighten up and support the lower part of the ice ocean to directly extract the ice sample after drilling through the ice surface.
Drawings
FIG. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention will now be described in more detail by way of example with reference to the accompanying drawings in which:
combine figure 1, elasticity drill bit 1 fixes under helix structure 2 and helix structure 3, and helix structure 2 and helix structure 3 pass through 4 fixed connection of helical connecting rod, and pivot 5 is fixed in 4 tops of helical connecting rod, and pivot 5 and gasoline engine 10 are connected to pivot connecting piece 6 to fix it through three bolt 7. The handle 8 and the handle 9 are arranged and fixed at two sides of the gasoline engine 10, and the gasoline tank 11 is arranged above the gasoline engine.
In the ice drilling process, the elastic drill bit 1 is fixed at a specific position on an ice surface, and the handle 9 and the handle 8 are respectively held by two hands to keep the balance of the drilling machine. The switch of the gasoline engine 10 is turned on, the gasoline engine 10 drives the whole drilling machine to rotate, and a large amount of ice chips appear on the ice surface along with the depth of the drill bit to sweep away the ice chips. When the elastic drill bit 1 penetrates through the ice layer, the handle 9 and the handle 8 are lifted forcibly, the whole drilling machine is taken up to be separated from the ice layer, and then the ice surface sampling is completed.
When the elastic drill bit 1 is immersed in a drilled-through layer of ice, the elastic drill bit 1 loses the outward tension of the ice sample on the elastic drill bit 1. Namely, the elastic drill bit 1 is tightened inwards to support the lower body of the ice sample and draw the ice sample away from the ice surface.
The invention relates to a test piece sampling device for an ice mechanical test, which is mainly applied to the technical field of ice surface sampling and comprises a gasoline engine 10 driving a rotating shaft to rotate, a double-helix structure body, a spiral connecting rod 4, a bolt 7, a rotating shaft connecting piece 6, an elastic drill bit 1, a gasoline tank 11 and handles 8 and 9. The device of the invention is characterized in that a rotating shaft 5 and a gasoline engine 10 are connected through a connecting piece of the rotating shaft 6 and fixed by a bolt 7, and the gasoline engine 10 is provided with symmetrical handles 8 and 9 which mainly play a role in keeping the balance of a drilling machine. The elastic drill bit 1 mainly has internal tension, and is contracted inwards after the ice surface is drilled through, so that an ice sample can be quickly extracted without other elements and devices. In the ice drilling process, a drilling position for taking an ice sample is fixed, the handle is held by two hands, the gasoline engine 10 is started, the drilling machine starts to rotate, and when the drill drills through the ice surface, the ice sample is quickly extracted, namely, one-time extraction of the ice sample is completed. In order to achieve higher drilling efficiency, the handle can be held by two persons.
