[0002] The grading screen, also known as the screening machine, is a commonly used screening machine in China. It is mainly used for the grading and screening of finished compound fertilizers. It is also suitable for the screening and grading of raw materials and finished products in various industries such as grain, food, chemical, sugar, mining, coal, metallurgy, papermaking, etc. The vibration is generated by the vibration motor and spring, with small amplitude and high frequency, ensuring that the material has large kinetic energy and inertia, and can form a self-cleaning effect. In addition, the machine has the characteristics of small size, easy operation, and reliable work. The grading screen needs to be used when processing rice.

[0003] Rice contains not only dust and rice husks, but also miscellaneous kernels which have certain recycling value and can be used to make fuel. Existing grading screens usually screen out dust and miscellaneous kernels together, which makes it inconvenient to separate the miscellaneous kernels from dust, making it difficult to collect the miscellaneous kernels. Therefore, improvement is needed. Utility Model Content
