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.
