Device for measuring friction coefficient of agricultural biomass plane

Abstract

The invention relates to a device for measuring a friction coefficient of an agricultural biomass plane and belongs to the field of agricultural engineering. The invention discloses a device for measuring the friction coefficient which is simple, feasible and convenient in reading in order to overcome the defects of the conventional measurement device. According to the technical scheme, a tilting plane which slowly ascends is formed; a sample is arranged on a steel plate on the tilting plane in a sample box, so that the bottom surface of the sample box is separated from the steel plate for a certain distance. In the process of slowly ascending the tilting plane, once the sample box starts to actively slide along the tilting plane, the tilting plane immediately stops ascending, and the friction coefficient value between the agricultural biomass and the steel plate is directly read by using an attached measuring scale. The friction coefficient measurement device disclosed by the invention has the advantages that (1) multiple samples can be simultaneously measured by debugging once, the time is saved, and the workload is reduced; (2) the friction coefficient is directly read, and the data processing is simple; (3) the structure is simple, the steel plate is replaced, and the friction coefficient between the agricultural biomass and other planar materials can be measured.
