[0008] Furthermore, a limiting ring block extending into the supporting side plate is connected to the outer side of the main rotating disc to facilitate the stable rotation operation of the main rotating disc.

[0009] Furthermore, the top of the support bottom plate is located inside the support side plate and is connected to both sides with a limit baffle, the inner side of the limit baffle is provided with a limit groove, and a collection box is placed in the limit groove, which is convenient for placing the collection box to collect the screened tea leaves.

[0010] Furthermore, a plurality of circular grooves are provided at the bottom of the limiting groove, and balls are rotatably provided in the circular grooves to facilitate the stable pushing and pulling operation of the collection box.

[0011] Furthermore, a support frame for supporting the supporting shaft is connected to the outer side of the supporting side plate, which facilitates the stable rotation operation of the supporting shaft.

[0012] The advantages of the tea grading and screening device of the present invention over the prior art are that the present invention can perform multi-stage screening operations on tea leaves through the electrically driven first-level screening mesh cylinder and second-level screening mesh cylinder, and can grade and screen the broken residue and crushed tea leaves in tea production.
