The servo motor 140 is installed in the inside of the first cavity 120. The end of the output shaft of the servo motor 140 is connected to the rotating rod 130 through a transmission part 150.

[0026] The box body 110 is fixed with a first holding portion 111 and a second holding portion 112. The first holding portion 111 is located at one side of the first cavity 120, and the second holding portion 112 is located at the end of the box body 110. Here, the first holding portion 111 and the second holding portion 112 are both holding frames, and the first holding portion 111 and the second holding portion 112 are arranged to facilitate holding. The transmission portion 150 includes a driving wheel 151 and a driven wheel 152. The driving wheel 151 is keyed to the end of the output shaft of the servo motor 140, and the driven wheel 152 is keyed to the rotating rod 130. The driving wheel 151 is meshed with the driven wheel 152. Here, through the arrangement of the transmission portion 150, the servo motor 140 can be used to conveniently drive the rotating rod 130 to rotate.

[0027] See also Figure 1-Figure 5 The extension and drainage structure 200 includes a support rod 210 and a drainage piece 250. The support rod 210 is fixed to the rotating rod 130. An extension tube 220 is slidably sleeved on the support rod 210. A second cavity 240 is fixed at the end of the extension tube 220. The drainage piece 250 is circumferentially installed on the second cavity 240.

[0028] A threaded column 230 is penetrated by a circumferential thread on the extension tube 220, and a hexagonal groove 231 is provided at one end of the threaded column 230, and the end of the threaded column 230 is in close contact with the surface of the support rod 210; a threaded hole matching the threaded column 230 is provided at one end of the extension tube 220, and the threaded column 230 is threadedly connected to the threaded hole. Here, a hexagonal wrench is inserted into the inside of the hexagonal groove 231, and the threaded column 230 is rotated to squeeze the end of the threaded column 230 against the surface of the support rod 210, so that the extension tube 220 is positioned and fixed to improve the stability of use.

[0029] There are three guide pieces 250, which are circumferentially distributed on the second cavity 240. The cross-section of the support rod 210 is a regular hexagon, and a socket matching the support rod 210 is formed inside the extension tube 220. This arrangement makes it easy to extend the extension tube 220.

[0030] The guide piece 250 includes a guide strip 251 and a movable column 252. The movable column 252 is fixed to the guide strip 251, and the movable column 252 slides through the second cavity 240. The end of the movable column 252 is fixed with a limit plate 253. The movable column 252 is sleeved with a spring 254.

One side of the guide strip 251 is inclined, and one end of the guide strip 251 is conical. The guide piece 250 is arranged here to facilitate the dredging of the feed pipe.

[0031] Specifically, the working principle of the drainage device of the feed pipe of the paint sand grinder is as follows: when in use, the extension tube 220 is pulled outward according to the length of the feed pipe, and then a hexagonal wrench is inserted into the corresponding hexagonal groove 231 on the threaded column 230 and rotated to squeeze the end of the threaded column 230 with the surface of the support rod 210, thereby fixing the extension tube 220, and then the drainage strip 251 is pressed to make the movable column 252 shrink toward the inside of the second cavity 240 under the elastic action of the spring 254, and then the drainage strip 251 is inserted into the feed pipe. Inside the tube, the elastic action of the spring 254 can make the drainage strip 251 fit with the inner wall of the feed tube. At this time, the first holding part 111 and the second holding part 112 can be manually held and the servo motor 140 can be started. The servo motor 140 drives the support rod 210 and the extension tube 220 to rotate under the action of the transmission part 150. The feed tube is unblocked by rotating the drainage piece 250. This can facilitate the fit with the inner wall of the feed tube to make the unblocking more complete, and at the same time it is easy to extend, which is more convenient to use to cope with feed tubes of different lengths.

[0032] It should be noted that the specific model and specifications of the servo motor 140 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.
