Description
Technical Field
[0001] The utility model relates to the technical field of sampling devices for foundation detection, in particular to a sampling device for foundation detection. Background Art
[0002] The soil sampler is used to lift the original 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, the soil sampler is often used for sampling and testing when testing the soil quality of the foundation. The soil sampler is placed on the surface of the foundation to be tested and pressed down, so that the soil sampler is inserted into the ground and lifted up to bring out the soil, thereby achieving the purpose of sampling.
[0003] The inventor discovered during daily use of a soil sampler that the soil of a general foundation is harder than normal soil, which makes it inconvenient for a normal soil sampler to be inserted into the ground during sampling, making it impossible to take samples, which in turn makes it impossible to complete foundation sampling, causing an impact. Utility Model Content
[0004] The utility model aims to solve the shortcomings in the prior art and proposes a sampling device for foundation detection.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a sampling device for foundation detection, including a soil sampling tube, a loosening device is arranged inside the soil sampling tube, a soil sampling rod is rotatably connected inside the soil sampling tube, a supporting device is arranged on the side of the soil sampling tube, and the loosening device includes a drill bit fixedly connected to one end of the soil sampling rod.
[0006] The effect achieved by the above components is: under the action of the drill bit, the soil at the location where soil needs to be taken can be loosened, thereby achieving the effect of facilitating sampling. When sampling is required, the soil sampling barrel is placed at the location where sampling is required, the soil sampling rod is rotated to loosen the soil edge, and the soil sampling barrel is pressed down to insert the soil sampling barrel into the soil, and the soil sampling barrel is pulled out, so that the soil is taken out, thereby completing the sampling.
[0007] Preferably, a drill plate is fixedly connected to the surface of the drill bit, and the drill plate is made of iron.
[0008] The effect achieved by the above components is that under the action of the drill plate, the drill bit can loosen the soil more quickly, thereby facilitating sampling.
[0009] Preferably, a spiral blade is fixedly connected to the surface of the soil-taking rod, and the spiral blade is arranged inside the soil-taking barrel.
[0010] The effect achieved by the above components is that, under the action of the spiral blade, the loosened soil can be transported into the interior of the soil extraction tube, thereby achieving the phenomenon of soil falling.
[0011] Preferably, one end of the soil taking barrel is fixedly connected with a circular groove, the interior of the circular groove is rotatably connected with a ball, and the surface of the soil taking rod is fixedly connected with a baffle, and the baffle is arranged at one end of the soil taking barrel.
[0012] The effects achieved by the above components are as follows: under the action of the baffle plate, the soil taking rod will not be fully extended into the interior of the soil taking barrel, thus avoiding the phenomenon that the soil taking rod is too short to affect soil drilling. When sampling soil, the soil taking barrel is placed vertically on the ground, and the soil taking rod is rotated to rotate the drill bit and the drill plate, thereby loosening the soil. During the soil drilling process, the soil taking rod moves downward, thereby allowing the drill bit to extend into the soil. When the soil taking rod is blocked by the baffle plate during its downward movement, under the action of the ball bearing, the baffle plate will not have large friction when rotating with the soil taking rod, and the soil taking rod will not move downward. After the soil is loosened, the soil taking barrel is stepped downward to be inserted into the soil, and the soil taking rod is rotated to rotate the spiral piece to transport the soil into the interior of the soil taking barrel, thereby achieving the effect of sampling, thereby achieving the effect of loosening the soil.
[0013] Preferably, the supporting device comprises a rectangular plate fixedly connected to the side of the soil collecting barrel, the side of the rectangular plate is rotatably connected to the supporting plate, the side of the supporting plate is fixedly connected to an elastic rope, and both ends of the elastic rope are fixedly connected to the bottom of the rectangular plate.
[0014] The effect achieved by the above components is that under the action of the support plate, the soil-taking barrel can be kept vertical to the ground and when the soil-taking barrel is stepped down, the operator can stand on the rectangular plate, thereby allowing the soil-taking barrel to be quickly inserted into the soil.
[0015] Preferably, a telescopic rod is fixedly connected to the bottom of the rectangular plate, and one end of the telescopic rod is fixedly connected to the square plate.
[0016] The effect achieved by the above components is that under the action of the telescopic rod, the soil-taking barrel can be supported, and the surface soil-taking barrel is tilted.
[0017] Preferably, a spring is sleeved on the surface of the telescopic rod, one end of the spring is fixedly connected to the bottom of the rectangular plate, and the other end of the spring is fixedly connected to the upper top of the square plate.
[0018] The effect achieved by the above components is that under the action of the spring, after the soil is taken out, the soil taking tube can be quickly drawn out from the soil.
[0019] Preferably, a groove is provided at the bottom of the support plate, and a rotating rod is rotatably connected inside the groove.
[0020] The effect achieved by the above components is as follows: under the action of the rotating rod, the support plate can quickly slide to both sides after the operator steps on the top of the rectangular plate, thereby avoiding the phenomenon that the support plate does not move due to large friction. When it is necessary to take soil, the operator steps on the upper top of the rectangular plate and rotates the soil taking rod to rotate the drill bit, so that the soil taking barrel is conveniently inserted into the soil. When the soil taking barrel is inserted into the soil, the support plate opens to both sides. Under the action of the rotating rod, the support plate can quickly slide to both sides after the operator steps on the top of the rectangular plate, thereby moving the soil taking barrel downward. When the soil taking is completed, the support plate is reset under the action of the elastic rope, and the soil taking barrel is quickly pulled out from the soil under the action of the spring and the telescopic rod, thereby achieving the supporting effect.
[0021] Compared with the prior art, the advantages and positive effects of the utility model are:
[0022] In the utility model, by arranging the loosening device, when sampling the soil, the soil sampling tube is placed vertically on the ground, the soil sampling rod is rotated, so that the drill bit and the drill plate are rotated, and the soil is loosened by drilling. During the soil drilling process, the soil sampling rod moves downward, so that the drill bit can be extended into the soil. When the soil sampling rod is blocked by the baffle plate in the process of moving downward, under the action of the ball, the baffle plate will not have a large friction when rotating with the soil sampling rod, and the soil sampling rod will not move downward. After the soil is loosened, the soil sampling tube is stepped downward to insert the soil sampling tube into the soil, and the soil sampling rod is rotated to rotate the spiral piece to transport the soil into the soil sampling tube, so as to achieve the effect of sampling, thereby achieving the effect of loosening the soil, thereby solving the problem that the soil sampling tube may not be inserted into the foundation when the soil sampling device is sampling the foundation.
