Description

Technical Field

[0001] The present invention relates to the technical field of soil sampling equipment, and specifically to a raw material protection device for soil sampling. Background Art

[0002] Soil refers to a layer of loose material on the earth's surface, which is composed of various granular minerals, organic matter, moisture, air, microorganisms, etc., and can grow plants. Soil is composed of minerals weathered from rocks, organic matter produced by the decomposition of animal and plant and microbial residues, soil organisms (solid phase substances), as well as moisture (liquid phase substances), air (gas phase substances), oxidized humus, etc. Soil samplers are one of the tools often used in environmental monitoring. Soil samples are taken out by the sampler, and then the soil samples are tested and analyzed to obtain various components contained in the soil, and then the degree of soil pollution is judged.

[0003] The soil samples taken by the most commonly used existing soil sampler are not complete, but only the samples at the bottom of the hole, resulting in incomplete soil samples taken by the sampler, and further reducing the accuracy of soil detection. On the other hand, after the soil is taken out, it is in a fragile state, so an institution needs to be designed to ensure the integrity of the soil. Summary of the Invention

After being pressed to a certain extent, the back core fixing rod grabs the core hole to fix it. After the sampling is completed, the overall spring is released, and the internal core spring provides a reset thrust. This process ensures that the sampled soil will not be broken during collection, and the stratification effect cannot be achieved.

[0015] (3) The present invention has a core telescopic rod fixedly connected inside, and a plurality of core telescopic rods are used to offset the huge reaction force generated by the core spring, so that the core middle plate moves slowly outward to avoid excessive pressure.

When the drilling is completed, it can prevent the top power mechanism from moving upward and the bottom soil from sliding downward, resulting in phenomena such as sample fragmentation and mixing. Moreover, when the core cutter moves outward and reaches the bottom, it will cut off the internal film. Brief Description of the Drawings

[0026] For example 2, please refer to Figure 4 - Figure 8, the present invention is a raw material protection device for soil sampling. On the basis of Example 1, the top power mechanism 2 further includes a power outer wall 204 rotatably connected to the inner wall of the overall main hole 103. At the top outer wall of the power outer wall 204, a power rotating ring 205 is fixedly connected. At the top outer wall of the overall top plate 102, a power motor 206 is fixedly connected. At the top outer wall of the power motor 206, a power large disc 207 is rotatably connected. A power belt 208 is sleeved on the outer wall of the power large disc 207. One end of the power belt 208 away from the power large disc 207 is rotatably connected to the inner wall of the power rotating ring 205. This power motor 206 provides power for the operation of the overall mechanism, driving the operation of the power saw teeth 209 and the power outer body 210 in the top power mechanism 2, achieving the effect of drilling soil samples.

[0027] The top power mechanism 2 further includes power saw teeth 209 fixedly connected to the outer wall of the power outer wall 204. A number of power outer bodies 210 are fixedly connected to the outer wall of the power saw teeth 209. A power bottom ring 211 is rotatably connected to the inner wall of the power outer wall 204. During the rotation of the power outer body 210, the surrounding soil is continuously broken, avoiding the phenomenon of jamming during the processing of the top power mechanism 2. The bottom closed design can ensure the safety of the film during the collection process, preventing the film from being damaged due to friction.

[0028] The internal core mechanism 3 further includes a core support 304 fixedly connected to the bottom outer wall of the power bottom ring 211. A number of core main rods 305 are rotatably connected to the inner wall of the core support 304. A number of one-way gears 306 are rotatably connected to the inner wall of the core main rods 305. Through the control of the one-way gears 306 by the power saw teeth 209, when the power motor 206 transmits a positive force, the one-way gears 306 are not affected and rotate along. When the power motor 206 transmits a reverse force, it will control the core main rod 305 to rotate and drive the internal film to cover.

[0029] The internal core mechanism 3 also includes a core spring 308 fixedly connected to the top outer wall of the core telescopic rod 310, the end of the core spring 308 away from the core top plate 301 is fixedly connected to the core middle plate 309, the top outer wall of the core middle plate 309 is fixedly connected to a plurality of core telescopic rods 310, the end of the core telescopic rod 310 away from the core middle plate 309 is fixedly connected to the bottom outer wall of the core top plate 301, the top outer wall of the core middle plate 309 is fixedly connected to a core fixing rod 311, and the outer wall of the core fixing rod 311 is connected to the core hole. The inner wall of 302 is slidably connected, and the core cutter 312 is fixedly connected to the bottom outer wall of the core middle plate 309. When the overall top plate 102 is squeezed downward by the equipment, an upward force is generated, and the back core spring 308 accumulates mechanical power. After being pressed to a certain extent, the back core fixing rod 311 grabs the core hole 302 to fix it. After the sampling is completed, the overall spring 111 is released, and the internal core spring 308 provides a reset thrust. This process ensures that the sampled soil will not be broken during collection, and the stratification effect cannot be achieved.

[0030] A specific application of this embodiment is: before using the present invention, the device is pushed to the desired position. In order to adapt to the frequent sampling effect in multiple places, the overall external mechanism 1 is movable, which is convenient for carrying and transportation. In addition, the overall telescopic rod 110 at the bottom cooperates with the overall spring 111, so that the device can adapt to various rugged environments. The overall rope 107 and the overall fixing nail 108 are closely fitted, thereby increasing the stability of the overall device during operation, which is conducive to reducing the shaking generated by the power motor 206 when it is working, and facilitating the subsequent sampling process. When the power of the power motor 206 is turned on, the overall top plate 102 generates an upward force when the device is pressed downward. The back core spring 308 accumulates mechanical power. After being pressed to a certain degree, the back core fixing rod 311 grabs the core hole 302 to fix it. After sampling is completed, the overall spring 111 is released, and the internal core spring 308 provides a resetting outward thrust. This process ensures that the sampled soil will not be broken during collection. Among them, the internal core telescopic rod 310 is fixedly connected. The huge reaction force generated by the core spring 308 is offset by several core telescopic rods 310, so that the core middle plate 309 moves slowly outward to avoid excessive pressure. When released, huge power is generated to shatter the collected sample, thereby achieving the effect of protecting the collected object.

[0031] When sampling, through the control of the one-way gear 306 by the power saw 209, when the power motor 206 transmits a forward force, the one-way gear 306 is not affected and rotates accordingly. When the power motor 206 transmits a reverse force, the main control rod 305 will rotate and drive the internal film to cover. When drilling is completed, it can prevent the soil at the bottom from sliding down when the top power mechanism 2 moves upward, resulting in phenomena such as sample fragmentation and mixing. When the core cutter 312 moves outward and reaches the bottom, it will cut off the internal film.
