Grinding and subpackaging equipment for farmland soil samples

Abstract

The invention discloses farmland soil sample grinding and separate packing equipment which comprises a grinding box. A coarse grinding cavity with an opening facing upwards is formed in the grinding box. A soil pulverizing device is arranged in the coarse grinding cavity. A vibration screening device located on the lower side of the soil pulverizing device is arranged in the coarse grinding cavity. A power device located at the lower side of the vibration screening device is arranged in the coarse grinding cavity. Two coarse grinding devices which are located at the lower side of the power device and are symmetric left and right are arranged in the coarse grinding cavity. A fine grinding device located at the lower side of the coarse grinding device located on the left side is arranged in the grinding box. The push coarse grinding devices provided by the invention utilize a double push rod mechanism, continuous push coarse grinding can be achieved, the coarse grinding efficiency is improved, and since the grinding devices imitate the manual grinding process, the grinding quality can be effectively improved; and therefore, the farmland soil sample grinding and separate packing equipment has the high soil pulverizing and grinding efficiency and good grinding quality, in addition, influences of impurities on soil sample analyzing can be effectively avoided, and a measured result is made high in precision.

Description

technical field [0001] The invention relates to the technical field of soil sample grinding and packaging, in particular to a farmland soil sample grinding and packaging equipment. Background technique [0002] Grinding and crushing of soil samples is the basic link in the analysis of soil nutrients and components and other related indicators in the laboratory. Different nutrient determination and component analysis have different requirements for the particle size of soil samples. The most commonly used ones are 0.15mm and 2mm. Two particle sizes, which require different grinding equipment and screens. The grinding and crushing of soil samples mainly include manual grinding and machine crushing. Manual grinding is easy to operate, low in cost, and does not pollute the sample. The experimental results obtained are highly accurate. , is more in line with the actual situation, suitable for laboratory processing with a small number of samples, but the manual grinding efficiency...
