Calculation of the degree of freedom of the sieving mechanism of the sieving machine

　　The degree of freedom of the sieve material mechanism of a sieve machine is the degree of freedom of movement of the sieve mesh in the sieve box. The calculation of the degree of freedom of the sieve material mechanism can be carried out by the following steps:

　　Determine the structure type of the screen box: according to the structure type of the screen box, you can determine the calculation method of the degree of freedom of the screen material mechanism. Common types of screen box structures include circular screen boxes, square screen boxes, etc.

　　2. Determine the movement of the screen: the movement of the screen can be divided into vibration and rotation. The free degree calculation of the vibrating sieve material mechanism needs to consider the vibration direction and vibration amplitude, while the free degree calculation of the rotating sieve material mechanism needs to consider the rotation angle and rotation speed.

　　3. Determine the support mode of the screen mesh: the support mode of the screen mesh can be divided into two types: hanging type and support type. The free degree of freedom calculation of the hanging sieve material mechanism needs to consider the position of the hanging point and the hanging method, while the free degree of freedom calculation of the supporting sieve material mechanism needs to consider the position of the supporting point and the supporting method.

　　4. Calculate the degree of freedom of the sieve material mechanism: according to the structure type of the sieve box, the movement mode of the sieve mesh and the support mode, the degree of freedom of the sieve material mechanism can be calculated. The specific calculation method can be determined according to the specific parameters and design requirements of the screening mechanism.

　　It should be noted that the calculation of the degree of freedom of the sieve mechanism is a complex engineering problem, which needs to consider a number of factors and parameters. It is recommended to refer to relevant engineering manuals or consult a professional engineer when performing the calculation.
