Description

Technical Field

[0001] The utility model relates to the technical field of soil detection, in particular to a soil sampler which is convenient to carry. Background Art

[0002] Soil testing is to evaluate soil quality, understand the content and distribution of pollutants in the soil, so as to plan rational land use and carry out effective pollution control. Soil testing can evaluate soil quality, which is an important indicator for measuring sustainable land use and the health of the ecological environment. Soil testing can be used to understand soil properties, bulk density, porosity, organic matter content, pH value and other indicators, thereby evaluating soil quality and fertility levels.

[0003] According to a publicly disclosed portable soil sampler (publication number: CN216559824U), in the above application, after the soil sampling is completed, when the soil sampler is pulled upward, the cover loses the squeezing force of the soil and gradually returns to its original position under the action of its own gravity and the restoring force of the flexible spring. After the flexible spring returns to its original position, it is stretched to the maximum stretching amount, and the cover will not be pushed by the gravity of the soil, so that the soil stays inside the inner cavity and will not fall, thereby ensuring the amount of soil sampled in a single time.

[0004] However, during actual use of the above-mentioned equipment, the soil to be tested is sampled through a soil sampler, but the soil sampler as a whole cannot be folded and disassembled, which causes inconvenience in the storage and carrying of the soil sampler as a whole. At the same time, soil will remain inside the soil sampler after the soil is collected, which will cause inaccurate detection during subsequent soil collection. In view of this, we propose a soil sampler that is easy to carry. Utility Model Content

[0005] The utility model aims to provide a soil sampler which is convenient to carry, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a soil sampler that is convenient to carry, comprising a soil sampler, a handle is arranged on the top of the soil sampler, the handle is convenient for the operator to hold it, the inner surface of the handle is fixedly connected to the outer surface of a fixed tube, a lifting platform is arranged on the top of the handle, the outer surface of the fixed tube is fixedly connected to the inner surface of a pedal, the pedal is convenient for the foot to step on, a portable mechanism is arranged on the outside of the fixed tube, and the portable mechanism includes:

[0008] An annular tube, the inner surface of the sliding rod is fixedly connected to the outer surface of the annular tube, the annular tube is convenient to fit on the inner wall of the sliding rod, an air blowing pipe is opened at the bottom of the annular tube, the air blowing pipe discharges the drawn air evenly, the side wall of the annular tube is connected to the side wall of the airbag through a pipeline, one end of the connecting rope is fixedly connected to the surface of the lifting platform, and the other end of the connecting rope is fixedly connected to the end of the hook;

[0009] A positioning hole is provided on the surface of the lifting platform, a pressure plate is provided on the top of the airbag, one end of a connecting rod is fixedly connected to the side wall of the pressure plate, the other end of the connecting rod is fixedly connected to the side wall of a sleeve, and a hanging hole is provided on the other side of the sleeve.

[0010] Preferably, the inner surface of the collar is slidably connected to the outer surface of the handle.

[0011] Preferably, the inner surface of the positioning hole is matched with the outer surface of the hook, and the outer surface of the hook is matched with the inner surface of the hanging hole.

[0014] Preferably, a side of the second magnet away from the first magnet is fixedly connected to a side wall of the pulling platform.

[0015] Compared with the prior art, the utility model provides a soil sampler that is easy to carry and has the following beneficial effects:

[0016] 1. The portable soil sampler can be used to extract air from the inside of the soil sampler by pressing the airbag when holding the handle after sampling. The soil sampler taps the ground with the threaded tube, which can decompose the fixed tube into two ends for quick installation and decomposition. The hook cooperates with the hanging hole to fold and connect the disassembled soil sampler, so as to avoid the overall length of the soil sampler being too long to be stored and carried. At the same time, the residual sample in the soil sampler is blown out during the disassembly process, so as to avoid the residual soil in the soil sampler causing the subsequent sampling accuracy to be reduced.

[0017] 2. The portable soil sampler is provided with a positioning hole so that the hook can be positioned after the soil sampling device is installed. The cooperation between the first magnet and the second magnet enables the soil sampling device to be positioned when connected after being disassembled, so that the disassembled parts of the sampling device can be stored or carried in a unified manner, thereby facilitating subsequent installation.
