Automatic Grinding Control Method of Fine Grinding Device

Abstract

The automatic grinding control method of the fine grinding device adopts the fine grinding device to implement the automatic grinding control of the ground, adjusts the parameters of the controller according to the test soil type through the fine grinding device, and starts the lifting motor and the grinding motor by the controller, and the grinding motor passes The grinding eccentric pin shaft connected with the grinding eccentric disk drives the grinding power plate to do grinding and rocking motion, and the pestle connecting column installed on the grinding power plate drives the pestle to make grinding and rocking motion in the mortar through the pestle connection spring, and the soil is The pestle is constantly squeezed and rubbed during the grinding and rocking movement, so as to grind the soil into homogenized and mixed soil powder particles, so as to ensure the grinding effect of batch soil samples, effectively save time and improve work efficiency; After all the test soil has been ground, the controller turns off the grinding motor, turns on the lifting motor to lower the lifting upper supporting plate, so that the mortar can be easily removed, so as to realize automatic fine grinding.

Description

technical field [0001] The invention relates to the technical field of test device control, in particular to an automatic grinding control method of a fine grinding soil device. Background technique [0002] In many basic research fields, such as soil science, agricultural water and soil engineering, etc., a large number of soil chemical experiments are required. In soil chemical experiments, the soil needs to be processed and ground. For example, the determination of soil nitrogen, phosphorus, and potassium requires 60-mesh soil analysis. Sieve (0.25mm), the determination of organic matter needs to pass through a 100-mesh soil analysis sieve (0.15mm), etc. Before the soil is sieved, tedious grinding work is required. The grinding process not only consumes a lot of manpower and material resources, but also has low work efficiency and soil grinding. Fine soil particles float in the air during the process, making the working environment harsh. Therefore, in order to solve the...
