Drying and grinding device for agricultural soil testing

Abstract

The invention discloses a drying and grinding device for agricultural soil testing. The drying and grinding device comprises a base, a grinding cylinder is fixedly arranged on the base through a bracket, the bottom of the grinding cylinder is in a funnel shape, and a discharging pipe is connected to the center of the bottom of the grinding cylinder; a first deceleration motor is fixedly disposed at the center of the top of the grinding cylinder, and a motor shaft at the bottom end of the first deceleration motor penetrates through the top wall of the grinding cylinder and is fixedly connectedwith a first rotating shaft; a grinding roller is fixedly mounted on the first rotating shaft, and the top of the grinding roller is in a taper shape; and grinding seats are fixedly arranged on the inner wall of the grinding cylinder, the grinding seats are provided with up-and-down penetrating cavities matched with the grinding roller, and the tops of the cavities of the grinding seats are in a circular truncated cone shape. Through the cooperation of the grinding seats and the grinding roller, soil is grinded, the distance between the circular truncated-cone-shaped cavities of the grinding seats and the tapered portion of the grinding roller is gradually decreased from top to bottom, so that the soil is gradually grinded from top to bottom, and the grinding effect is better.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a drying and grinding device for agricultural soil detection. Background technique [0002] With the development of science and technology, the times are advancing, and people's living standards are gradually improving. However, due to the gradual reduction of people's attention to the ecosystem, soil pollution has been serious in recent years, which has further affected people's health; When conducting investigations, we often collect soil for analysis of chemical elements and test various indicators. In the process of soil testing, grinding is an essential step. The recovered soil needs to be ground to better cooperate with experiments. Check various standards. [0003] The more traditional method is to put the soil in a mortar, crush and grind it manually with a small hammer, so that people's arms will feel numb and tired after a long time, and many testing dep...

Problems solved by technology

[0003] The more traditional method is to put the soil in a mortar, crush and grind it manually with a small hammer, so that people's arms will feel numb and tired after a long time, and many testing departments use electric grinders, although it solves the problem of manual grinding The problem of easy fatigue, but there are still many deficiencies, such as the sanding of the soil is not fine enough, and the ground soil is not conducive to detection; the soil is easy to stick and difficult to grind
