Description

Technical Field

[0001] The utility model relates to the technical field of soil extractors, in particular to a novel shallow soil extractor. Background Art

[0002] A soil sampler is a device used to extract soil as a sample, and then to understand the soil. It is mostly used in engineering geological exploration, environmental science and agricultural work. When using a soil sampler, you first need to drill the soil sampler into the soil to the required depth, then pull it out, remove the ring knife and semi-cylinder, scrape off and smooth the excess soil at both ends of the soil sampler, and the soil in the ring of the soil sampler is the required sample.

[0003] The current soil extractor structure is generally as described in a telescopic soil extractor disclosed in the patent application number "CN202322774846.8", including a soil extractor. The soil extractor includes a soil drill tube, a fixed rod, a lifting rod, a limit rod, an elastic member and a bulldozer. When in use, the limit rod is pulled out of the limit through hole, and then the lifting rod can be moved upward, and then the soil drill tube can be used to extract soil. After the soil is extracted, the limit rod is pulled out of the limit through hole, and then the lifting rod can be moved downward. The lifting rod drives the bulldozer to move downward, and then the bulldozer can push the soil inside the soil drill tube. The lifting rod can enter the soil drill tube and the fixed rod, and then the overall length of the soil extractor can be shortened, and then the portability of the soil extractor can be increased. The soil inside the soil drill tube can be pushed out by the bulldozer. However, in the process of taking soil samples from the soil, the original structure of the soil is easily destroyed, and the stability during the sampling process cannot be guaranteed.

[0004] Therefore, the utility model proposes a novel shallow soil taking device to solve the above-mentioned problems. Utility Model Content

[0014] By adopting the above technical solution, the soil condition inside the sampling tube can be observed through the observation window, and when there are abnormal conditions such as impurities in the soil sample, it can be discarded in time, avoiding the next step of work and reducing manpower waste.

[0015] Furthermore, a scale is provided on the fixing rod.

[0016] By adopting the above technical solution, the working distance of the sampling tube can be adjusted according to work requirements, and the scale can read the sampling depth of the sampling tube more intuitively, thereby improving the accuracy and efficiency of sampling.

[0017] Furthermore, the sliding cylinder is connected to a rotating handle, and the rotating handle is connected to an anti-slip layer.

[0018] By adopting the above technical solution, the sliding cylinder can be dropped by turning the handle so that the sliding cylinder is inserted into the soil. The anti-skid layer can prevent slipping, so that the operator can operate the soil extractor more stably and safely.

These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific direction, or to be constructed and operated in a specific direction.

[0031] like Figure 1 As shown, a novel shallow soil sampler comprises a sampling tube 1, the upper end of which is detachably connected with a telescopic assembly, the telescopic assembly comprising a fixed rod 2 and a sliding tube 3, the fixed rod 2 being threadedly connected to the sampling tube 1; the fixed rod 2 is slidably connected in the sliding tube 3, the sliding tube 3 is threadedly connected with a positioning rod 5, and the fixed rod 2 is provided with a positioning groove 6 corresponding to the positioning rod 5; the lower end of the sampling tube 1 is convexly arranged, and a ring knife 12 is connected to the circumference of the lower end of the sampling tube 1. The convex arrangement enables the sampling tube 1 to be inserted into the soil more stably to avoid displacement during the sampling process, and the ring knife 12 can cut the soil sample to ensure that the soil sample can be completely taken out while avoiding deformation of the soil sample. The interior of the sampling tube 1 is connected with a partition 13, which is arranged at the lower end of the second connecting rod 10. The soil sample can be isolated to avoid the soil sample affecting the operation of the second connecting rod 10. An observation window 14 is provided on the sampling tube 1. The soil condition inside the sampling tube 1 can be observed through the observation window 14, and when there are abnormal conditions such as impurities in the soil sample, it can be discarded in time, avoiding the next step of work and reducing manpower waste.

[0032] like Figure 2 As shown, a scale 15 is provided on the fixing rod 2, so that the working distance of the sampling tube 1 can be adjusted according to working requirements. The scale 15 can read the sampling depth of the sampling tube 1 more intuitively, thereby improving the accuracy and efficiency of sampling.

[0033] like Figure 2 and Figure 3As shown, a rotating handle 16 is connected to the sliding cylinder 3, and an anti-skid layer 17 is connected to the rotating handle 16. Then, the operator can lower the sliding cylinder 3 by rotating the handle 16, so that the sliding cylinder 3 is inserted into the soil, and the anti-skid layer 17 can prevent slipping, so that the operator can operate the soil extractor more stably and safely. An anti-collision pad 18 is connected to the upper end of the sliding cylinder 3. Then, during the soil extraction process, when the sampling cylinder 1 needs to be dropped by external force, the anti-collision pad 18 can absorb the impact force, avoid direct impact on the sliding cylinder 3, and avoid deformation or damage to the soil extractor.

The scale 15 can read the sampling depth of the sampling cylinder 1 more intuitively, and then the position of the sliding cylinder 3 is fixed by the positioning rod 5. When the sampling cylinder 1 completes sampling of the soil sample, the handle 8 is moved upward, and then the handle 8 drives the first connecting rod 7 to move upward, and then the first connecting rod 7 drives the second connecting rod 10 to move upward, and the second connecting rod 10 drives the claw 11 to rotate, thereby fixing the soil sample in the sampling cylinder 1, and then the sampling cylinder 1 is pulled out from the ground, contacting the limit of the handle 8, and the handle 8 is reset by the reset spring 9, thereby releasing the fixation of the soil sample.
