The drill rig is not only simple to operate, but also easy to carry and can be used anytime and anywhere. In addition, it has a variety of sampling heads to meet different geological conditions and sample requirements; a sampling window is installed on one side of the cylindrical drill bit in the existing gasoline-powered soil sampler. After the sampling window is removed each time, the sampled soil in the drill bit can be taken out from the side of the drill bit, making sampling more convenient and quick.

[0003] However, both ends of the existing sampling window are installed on the above-mentioned drill bit through a clamping and self-locking mechanism. Each time the sampling window is opened, the sampling window and the drill bit body will be completely separated. After the sampling window is completely separated and disassembled from the drill bit body, it is easy to cause the sampling window to be lost due to human factors. This article aims to propose a gasoline-powered soil sampler drill bit in which the sampling window and the drill bit body are always connected. Utility Model Content

[0004] The utility model aims to solve the problem that the sampling window on the drill bit of a gasoline-powered soil sampler in the prior art is easily lost due to human factors after the sampling window is completely separated from the drill body each time the sampling window is opened. A soil collection device for soil detection is proposed to solve the problem that the sampling window is easily lost due to human factors after the sampling window is completely separated from the drill body.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0022] See attached Figure 1-3 A soil collecting device for soil detection comprises a drill tube 1, and a plurality of saw teeth 3 and a plurality of bevel teeth 4 are fixedly installed on the opening edge of the lower end of the drill tube 1. The plurality of saw teeth 3 are evenly distributed in a circular shape and arranged just below the opening edge of the drill tube 1, and are mainly used for drilling holes downward. The plurality of bevel teeth 4 are respectively arranged on the inner sides of the plurality of saw teeth 3, and the lower ends of the bevel teeth 4 are inclined toward the central axis direction of the drill tube 1. The plurality of bevel teeth 4 are used to thin the outer circle of the soil column entering the drill tube 1, that is, the outer diameter of the soil column entering the drill tube 1 is slightly smaller than the inner diameter of the drill tube 1, that is, the above-mentioned soil column can enter the drill tube 1 more easily, and the drill tube 1 is used to ensure the integrity of the cross section of the soil column in the inner cavity, and secondly, the inclined parts at the ends of the plurality of bevel teeth 4 are used to limit the backflow of the soil column entering the drill tube 1, and a threaded joint 6 is fixedly installed on the top of the drill tube 1.

[0023] In this embodiment, a sampling window is provided on one side of the drill bit barrel 1, and a sampling window 2 is rotatably installed on one side of the sampling window through a rotating shaft 16. A card slot 9 is provided on one side of the sampling window 2, and an installation groove 5 corresponding to the card slot 9 is provided on one side of the sampling window, and a self-locking mechanism is installed in the installation groove 5.

[0024] In this embodiment, the self-locking mechanism includes a vertical rod 14, a clamping rod 8 and a plurality of hinge rods 10. The vertical rod 14 and the clamping rod 8 are parallel to each other. The vertical rod 14 is fixedly installed in the installation groove 5. The head ends of the plurality of hinge rods 10 are rotatably installed on one side of the vertical rod 14. The tail ends of the plurality of hinge rods 10 are rotatably installed on one side of the clamping rod 8. A plurality of limit plates 12 are also fixedly installed on one side of the vertical rod 14. The plurality of limit plates 12 are respectively contacted with the upper ends of the plurality of hinge rods 10. The limit plates 12 are used to limit the rotation angle of the hinge rod 10.

[0025] In this embodiment, tension springs 11 are stretched between several hinge rods 10 and vertical rods 14, and several tension springs 11 are respectively arranged above several hinge rods 10. The tension springs 11 in this application are always in a stretched state, and through the elastic tension of the tension springs 11, they are used to pull the ends of several hinge rods 10 to rotate upward at the same time and abut against the lower ends of several limit plates 12. When the tension springs 11 pull the ends of the hinge rods 10 to rotate upward and abut against the lower ends of the limit plates 12, the ends of the hinge rods 10 and the clamping rods 8 rotate out of the mounting groove 5, and are used to slide into the clamping groove 9 in the sampling window 2.

[0026] It should be added that the angle between the limit plate 12 and the vertical rod 14 is less than 90°, which is mainly used to limit the rotation angle range of the hinge rod 10 to less than 90°, thereby preventing the hinge rod 10 and the vertical rod 14 from being perpendicular to each other, thereby preventing the hinge rod 10 from being in a dead point position, and always ensuring that the hinge rod 10 can rotate when the clamping rod 8 is pressed toward the vertical rod 14.

[0027] In this embodiment, a cover plate 15 is fixedly installed on the top of the vertical rod 14, and the cover plate 15 is fixedly installed on the top of the drill tube 1. An operating rod 7 is installed in the cover plate 15 for lifting and lowering. The top end of the operating rod 7 passes through the drill tube 1 upward, and the lower end of the operating rod 7 is hinged with a chain plate 13. The lower end of the chain plate 13 is hinged above the uppermost hinge rod 10. A top cap 17 is fixedly connected to the top of the operating rod 7. The top cap 17 is pressed downward, and the operating rod 7 and the ends of the hinge rod 10 are rotated downward, thereby driving a plurality of hinge rods 10 and the clamping rod 8 to rotate hidden in the mounting groove 5.

[0028] In the utility model, when the drill tube 1 is in use, the plurality of saw teeth 3 and the plurality of bevel teeth 4 are simultaneously rotated to cut into the soil. The plurality of saw teeth 3 are mainly used to assist the drill tube 1 in drilling downwards, and the plurality of bevel teeth 4 are used to thin the outer ring of the soil column entering the drill tube 1, so that the sampled soil column can enter the drill tube 1 more easily, and the integrity of the soil column section in the inner cavity can be better guaranteed. In addition, the inclined parts at the ends of the plurality of bevel teeth 4 restrict the soil column entering the drill tube 1 from flowing back out, that is, after the drill tube 1 is sampled and pulled out of the soil, the plurality of bevel teeth 4 can better cut off the soil entering the drill tube 1 and the soil below, and the soil in the drill tube 1 can be taken out more completely.

[0029] After the sampling of the drill tube 1 is completed, it is only necessary to press down the top cap 17, and then the operating rod 7 and the hinge rod 10 are driven to drive the ends of the hinge rods 10 and the clamping rods 8 to rotate hidden in the mounting groove 5, thereby releasing the restrictions of the ends of the hinge rods 10 and the clamping rods 8 on the sampling window 2, and the sampling window 2 can be manually opened. The operation is simple, and the sampling window 2 can be always connected to the drill tube 1 through the rotating shaft 16, ensuring that the drill tube 1 and the sampling window 2 are always connected and are not easily forgotten or lost.

[0030] It should be noted that the present application uses a self-locking mechanism, and the sampling window 2 can be closed by only rotating the sampling window 2 to cover the sampling window of the drill bit barrel 1. Compared with the traditional sampling window 2, there is one less clamping process, and the operation is more convenient. When the sampling window 2 is opened, the self-locking mechanism mainly uses the elastic tension of several tension springs 11 to pull the ends of several hinge rods 10 to rotate upward at the same time until they rest against the lower ends of several limit plates 12, and rotate the ends of the hinge rods 10 and the clamping rod 8 to pass through the mounting groove 5. Then, when closing the sampling window 2, the sampling window 2 first compresses the ends of the hinge rod 10 and the clamping rod 8 into the mounting groove 5, until the mounting groove 5 and the clamping groove 9 are connected to each other, and then the several tension springs 11 pull the ends of the several hinge rods 10 to rotate upward at the same time again, and are used to slide into the clamping groove 9 in the sampling window 2 to limit the movement of the sampling window 2, thereby completing the self-locking of the sampling window 2.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
