Problems solved by technology
In soil agrochemical analysis, in order to test the physical and chemical physical and chemical indicators of soil particle composition, pH, Ec, total and effective content of nitrogen, phosphorus and potassium nutrients, and heavy metal elements (such as cadmium, lead, chromium, copper, zinc, etc.) In the early stage of the test, the analysis samples need to be crushed to obtain samples of different particle sizes in order to meet the needs of different test items. However, the traditional crushing of soil samples is generally done manually, which is labor-intensive. And it takes a long time, so it still can't complete the crushing operation well

The invention discloses a novel soil crusher for biological experiments. The novel soil crusher for biological experiments comprises a trolley frame composed of a trolley body, supporting racks and aninstallation plate. The two supporting racks are fixedly installed on the trolley body correspondingly in a left and right manner. The installation plate is fixedly installed at the upper ends of thetwo supporting racks. A first oil cylinder is fixedly installed in the center of the upper end face of the installation plate. A first telescopic rod connected with the first oil cylinder is movablyinstalled in the center of the installation plate. A crushing head is fixedly installed at the lower end of the first telescopic rod. A console is installed on the upper end face of the trolley body,and located under the crushing head. The console comprises a fixed plate and a sleeve. The fixed plate and the sleeve are movably connected in a matched manner. The bottom end of the fixed plate is fixedly connected with the trolley body. An elastic piece is fixedly installed between the lower end of the sleeve and the trolley body. A pushing plate is further installed in the sleeve movably. A second telescopic rod is movably installed in the fixed plate. The upper end of the second telescopic rod is fixedly connected with the pushing plate. The lower end of the second telescopic rod is connected with a second oil cylinder which is fixedly installed in the fixed plate.
Description
technical field [0001] The invention relates to the field of soil analysis and testing, in particular to a novel soil crusher for biological experiments. Background technique [0002] In recent years, with the popularization of soil testing and formula fertilization technology, heavy metals and pesticides and other soil pollution incidents have occurred frequently, and the soil quality and soil environmental safety have gradually attracted people's attention. On this basis, soil agrochemical analysis has been fully understood and affirmed, and has made great progress, and the workload of soil sampling and analysis is increasing day by day. In soil agrochemical analysis, in order to test the physical and chemical physical and chemical indicators of soil particle composition, pH, Ec, total and effective content of nitrogen, phosphorus and potassium nutrients, and heavy metal elements (such as cadmium, lead, chromium, copper, zinc, etc.) In the early stage of the test, the ana...
