On the other hand, it is beneficial for the drill rod to avoid harder stones in the soil and reduce the chance of damage to the drill rod, thereby extending the service life of the drill rod and further improving the safety of the sampler during use.

[0019] By turning on the third motor on the drilling assembly, the scraper can scrape the soil drilled by the drill rod on the bottom plate into the discharge pipe, which is conducive to the smooth discharge of the soil sample drilled by the drill rod through the discharge pipe. Secondly, the fourth motor on the packaging assembly is turned on to facilitate the rotating plate to move the storage troughs on the several baffles to the bottom of the discharge pipe in turn, and the first hydraulic cylinder on the sealing assembly drives the baffle at one end of the first hydraulic rod to move, which is conducive to discharging the soil samples at different layers sampled by the sampler into the dry storage troughs for classification and collection, so as to better understand the nutrient content, bulk density, water retention capacity and other indicators of the soil at different layers, thereby helping the staff to better evaluate the quality of the soil. At the same time, the second hydraulic cylinder on the pressing assembly drives the second hydraulic rod to move up and down, so that the pressing plate can collect all the soil samples in the discharge pipe into the storage trough on the packaging assembly, and avoid the situation where the soil sticks to the inner wall of the discharge pipe and causes blockage, which is conducive to keeping the discharge pipe clean and tidy, and is conducive to the continuous discharge operation of the discharge pipe.

At the same time, the sampler automatically completes the sample collection and packaging operations of different soil layers, making the automation degree of the soil sample collection operation of the sampler higher, which is further conducive to improving the work efficiency of the soil sample collection of the sampler. At the same time, by classifying, collecting and storing soil samples, on the one hand, it is not only conducive to saving manpower, but also conducive to quickly and accurately completing the soil sampling and packaging process, and also conducive to reducing the chance of staff contact with harmful substances and reducing work risks.
