Description

Technical Field

[0001] The utility model belongs to the technical field of soil detection, and in particular relates to a soil pre-detection pretreatment device. Background Art

[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. After soil sampling, it needs to be processed and tested to ensure the accuracy of the test results;

[0003] A soil detection pretreatment device is disclosed in the related art (publication number: CN219179027U), and the disclosed technical solution is as follows: a blocking unblocking mechanism is arranged in the screening box, and the blocking unblocking mechanism is composed of a shuttle-shaped moving block, a rotating connecting rod and a matching structure thereof. When the screen hole is blocked by a pile of stone fragments, the blocking unblocking mechanism reciprocates, and the insert rod is used to penetrate and unblock the screen hole in real time, so that the blocking unblocking work can be carried out in real time during the screening process, so that the whole screening process can be carried out in an orderly manner, and the power source of the blocking unblocking mechanism and the crushing mechanism are the same power source, so that the power source is saved, and the crushing and unblocking can be carried out at the same time, further ensuring the orderly progress of the screening process;

[0004] In the above disclosed technical solutions, the following problems are found in the related technologies: during the screening process, when the shuttle-shaped moving block is screening in the screening bucket, the crushed soil may fall into the gap between the shuttle-shaped moving block and the screening bucket due to the small size of the crushed soil. With the continuous screening process, the edge of the shuttle-shaped moving block is worn, which causes the edge gap to become larger, resulting in the falling of crushed stones, affecting the screening effect of the soil. In this regard, we propose a new soil pre-detection pretreatment device;
