[0002] Through soil testing, we can understand the content of various nutrients in the soil, such as mineral elements such as nitrogen, phosphorus, potassium, and physical and chemical properties such as organic matter and pH value, which can provide a scientific basis for agricultural production, make agricultural operations such as fertilization and irrigation more targeted, and improve the yield and quality of agricultural products. Before testing the soil, it is necessary to collect it and then test it;

[0003] A related art (authorization announcement number: CN209296366U) discloses a soil collection device for soil environment detection, and the disclosed technical solution is as follows: through the structural design of the outer rod, the inner rod and the fixing bolt, it is convenient for the user to adjust the height between the fixed disc and the ground, and it is also convenient for the user to stand the fixed disc on the disc, and then through the structural design of the rotating motor and the second rotating gear, the second rotating gear can drive the first rotating gear to rotate so that the rotating sleeve can rotate, and then through the structural design between the rotating sleeve, the bearing and the fixed disc, the rotating sleeve can not drive the fixed disc to rotate when rotating;

[0004] In the above disclosed technical solutions, the following problems are found in the related technologies: in the process of collecting soil by drilling, since the rotating sleeve is connected to the drilling rod by threads, and the drill bit drives the drilling rod into the soil to take it out, the soil will be brought out from the gap of the outer threads of the drilling rod, so that the drilling rod and the rotating sleeve threads are matched, resulting in the drilling rod being unable to be taken out, which brings inconvenience to the relevant personnel in the sudden collection process. In this regard, we propose a new type of soil detection collection device;
