Description

Technical Field

[0001] The utility model relates to the technical field of soil collection, in particular to a soil sampler. Background Art

[0002] In engineering geological exploration and survey work, in order to obtain the physical and mechanical performance indicators of foundation soil, in addition to in-situ testing, the main method is to conduct indoor geotechnical experiments after drilling sampling. To obtain undisturbed soil samples close to natural structures, the key lies in improving sampling technology and using advanced soil sampling devices. The soil sampling device is used to lift the undisturbed soil of the lower test soil as a sample to understand its properties. In order to better understand the properties of the base layer, and in engineering geological exploration and survey work, in order to obtain the physical and mechanical performance indicators of foundation soil, sometimes it is even necessary to take undisturbed soil at a deeper depth, and this soil sampling equipment is called a soil sampling device.

[0003] However, the soil sampling device commonly used at present directly inserts the soil sampling drill bit into the ground when sampling soil, which makes it difficult to sample deep soil and it is difficult to take out the relatively compact soil, making subsequent exploration work difficult.

When it is necessary to take soil, the motor 403 is started, and the motor 403 drives the first gear 402 to rotate, the first gear 402 is meshed with the second gear 404, and the second gear 404 rotates together with the first gear 402, the rotating shaft 405 at the bottom of the second gear 404 and the rotating drum 406 fixedly installed at the end of the rotating shaft 405 rotate together, and the spiral drill bit 407 at the bottom of the rotating drum 406 plays the role of drilling the soil and sending the soil into the rotating drum 406.

[0033] Reference Figure 1-Figure 4Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that the rotating drum 406 is hollow, and a soil collecting plate 5 is slidably installed in the inner cavity of the rotating drum 406. The rotating shaft 405 is hollow, and a connecting rod 6 is slidably installed in the inner cavity of the rotating shaft 405. The bottom of the connecting rod 6 is fixedly connected to the soil collecting plate 5. The connecting rod 6 penetrates to the top of the second gear 404 and is slidably connected to the second gear 404. In this way, when the second gear 404 rotates, the connecting rod 6 rotates with the second gear 404 and can slide up and down. The rotating drum 406 and the side of the chassis 1 of the soil collecting plate 5 are both rotatably installed with a rotating rod 7, and the ends of the rotating rod 7 are both installed There are universal wheels 8, and a limit block 9 fixedly installed on the side wall of the chassis 1 is arranged on the top of the rotating rod 7. The rotating rod 7 is blocked by the limit block 9, supporting the universal wheel 8. When the machine needs to be started, the rotating rod 7 is pushed outward, and the universal wheel 8 is turned over on the ground because there is no supporting point. The whole machine will be supported by the chassis 1, and the screw rod 3 passes through the top of the bracket 2. An annular handle 10 is fixedly installed on the top of the screw rod 3, and a control handle 11 is fixedly installed on the top of the connecting rod 6. The screw rod 3 is used to control the drilling depth of the spiral drill bit 407. At the same time, the support rod 401 threadedly installed on the outer wall of the screw rod 3 moves up and down with the soil taking mechanism 4.

[0034] Specifically, the working process or working principle of the soil extractor is as follows: after the working location is selected, the soil collecting plate 5 falls into the hollow spiral drill head 407 under the action of gravity, and then the universal wheel 8 is toggled in the direction away from the limit block 9 to separate the rotating rod 7 from the limit block 9. When the rotating rod 7 is not supported by the limit block 9, it will continue to rotate until the chassis 1 is connected to the ground, and the machine is fixed on the ground, and then the motor 403 is started, and the motor 403 drives the first gear 402 to rotate, the first gear 402 drives the second gear 404 to rotate, the second gear 404 drives the rotating shaft 405 to rotate, the rotating shaft 405 drives the rotating drum 406 to rotate, and the rotating drum 406 drives the spiral drill head 407 to rotate, and the entire soil extractor is completed. After the mechanism 4 is started, the annular handle 10 is rotated to drive the screw rod 3 to rotate, and the support rod 401 threadedly installed on the outer wall of the screw rod 3 begins to move downward, and the support rod 401 moves the entire soil-taking mechanism 4 downward together. After the spiral drill bit 407 drills the soil to the specified position, the rotating drum 406 also collects the soil inside under the action of pressure. After the soil is collected, the screw rod 3 is rotated in the opposite direction to lift the entire device. After the spiral drill bit 407 leaves the ground, the rotating rod 7 is reset, the entire device is pushed away, and then the control handle 11 is pressed downward. The control handle 11 moves downward with the connecting rod 6 and the soil collecting plate 5 until the soil falls out of the opening of the spiral drill bit 407, and then soil detection is started.

[0035] It should be noted that the motor 403 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
