[0032] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0033] First embodiment like Figure 1-5 As shown, a continuous ball mill matcha machine includes a barrel 1, a feeding device 2, a transmission shaft 3, a stirring rod 4, a cooling device and a driving device. The driving device includes a frame 51, a motor 52, a coupling 53 and a bearing seat 54. The motor 52 is a conventional motor 52 that can be directly purchased on the market, which is fixedly mounted on the frame 51; the coupling 53 is fixed on the output shaft of the motor 52, and is used to connect the motor 52 and the transmission shaft 3; the bearing seat 54 is provided at both ends of the transmission shaft 3 and is fixedly mounted on the frame 51; the stirring rod 4 is evenly fixed on the transmission shaft 3, and is used to turn over the raw materials and grinding balls.

The collecting pipe 66 and the delivery pipe 67 can be used for the grinding balls to move. When processing tea leaves, the cooling liquid enters the cooling chamber from the water inlet pipe 63, absorbs the heat of the cylinder 1, and is then discharged from the water outlet pipe 64, thereby cooling the cylinder 1. While cooling the cylinder 1, the grinding balls will be continuously pushed into the chute 65 by the collecting component, and the grinding balls will slide along the chute 65 and fall into the through hole, and then roll along the collecting pipe 66 to the delivery pipe 67. During the rolling process, the heat of the grinding balls will be transferred to the wall of the delivery pipe 67. Since most of the delivery pipe 67 is located in the cooling chamber, the heat of the delivery pipe 67 will be taken away by the cooling liquid, thereby cooling the grinding balls, and the grinding balls are continuously pushed to move in the delivery pipe 67 by the driving component, so that the grinding balls fall back into the cylinder 1 from the end of the delivery pipe 67.

[0035] Specifically, the collecting assembly includes a connecting rod 681, a scraper 682 and a control component. The connecting rod 681 is evenly arranged on the transmission shaft 3; the scraper 682 is connected to the connecting rod 681, and the scraper 682 can fit the inner wall of the cylinder 1.
