Description

A kind of Chinese chestnut sheller safety guard net using expansion principle

Technical field

It is specially a kind of to be peeled off using the Chinese chestnut of expansion principle the utility model relates to Chinese chestnut sheller technical field Equipment safety guard net.

Background technique

Thermal expansion typically refer to outer pressure it is constant in the case where, most of substances when the temperature rises, volume increase, temperature Volume-diminished when degree reduces.It is thermal expansion and temperature, thermal capacitance, related in conjunction with energy and the physical properties such as fusing point.Influence material expansion The principal element of performance is the influence of phase transformation, material composition and tissue, each opposite sex.The measurement method of thermal expansion mainly includes optics Method, electrical measuring method and Mechanical Method.Entry is in the coefficient of volume expansion for finally giving common liquid and the linear expansion of various metals Coefficient, under the same conditions, gas expansion are maximum, and liquid expansion is taken second place, and expansion of solids is minimum.Also there are a small number of substances certain In temperature range, when temperature increases, volume reduces instead.Because when object temperature increases, the mean kinetic energy of molecular motion increases Greatly, intermolecular distance also increases, and the volume of object expands therewith；Temperature reduces, the mean kinetic energy of molecule when object is cooling Become smaller, shorten intermolecular distance, then the volume of object will reduce.Again due to solid, liquids and gases molecular motions Mean kinetic energy is of different sizes, thus also has significant difference from the point of view of the macroscopic appearance of thermal expansion.

General sheller when in use, starts motor to be usually located at outside of deivce face, chain is carried out between axis and axis Connection, chain rotates when work, if accidentally touching can bring safety accident to operator, it is therefore desirable to safety guard net to its into Row isolation.
