Description

technical field

[0001] The invention relates to an agricultural mechanical equipment, in particular to a straw torsion measuring device. Background technique

[0002] Because the mechanical properties of straw materials are quite different from those of engineering materials, the force deformation is large, the size and shape are irregular, and it is not easy to process into suitable samples, so the determination of the mechanical properties of straw materials is difficult to achieve; On the one hand, the commonly used equipment and testing methods are immature, and simple manual test devices are mostly used; on the one hand, the measurement accuracy and research efficiency are low; The actual working conditions; the more important problem is that in actual production, due to complex working conditions and harsh environments, it is often difficult to obtain relevant test parameters. Contents of the invention

[0003] The technical problem to be solved by the invention is ...
