[0020] Please see Figs. 1-3 This utility model provides a technical solution: a ball mill feeding device, including a feeding pipe 1 and a feeding hopper 2. The feeding pipe 1 is provided with a feeding inlet 101 at the top and a feeding outlet 102 at the end. The feeding hopper 2 is provided with a discharge port 203 at the bottom, which is connected to the feeding inlet 101. A cover plate 201 is provided above the feeding hopper 2, and a feeding port 202 is provided on the cover plate 201. A telescopic motor 3 is provided on the side of the feeding hopper 2. The telescopic motor 3 is vertically arranged and fixed to the feeding pipe 1. An installation plate 301 is fixed to the output end of the telescopic motor 3. The installation plate 301 extends above the cover plate 201 and is fixed with a first drive motor 4. A rotating rod 5 is connected to the drive shaft of the first drive motor 4. The rotating rod 5 passes through the cover plate 201 and is inserted into the feeding hopper 2, where a plurality of crushing blades 501 are connected. By adding material into the feed hopper 2, the first drive motor 4 is started to drive the rotating rod to rotate, and the crushing blade 501 on the rotating rod 5 is used to crush the material. During the process, the telescopic motor 3 can be used to drive the crushing blade 501 to move up and down.

[0021] Furthermore, a discharge valve 2031 is provided on the discharge port 203. After the material is crushed in the feed hopper 2, the discharge valve 2031 can be opened to send the crushed material to the feed pipe 1 for conveying.

[0022] Furthermore, a conical head 502 is fixed to the end of the rotating rod 5, and the outer side of the conical head 502 is spiral-shaped. The conical head 502 is provided to control the rotating rod 5 to move downward after the discharge valve 2031 is opened, so that the conical head 502 can extend into the discharge port 203 to achieve the effect of material passage and avoid blockage.

[0023] Furthermore, a plug 2021 is provided on the feeding port 202. When adding material to the feeding hopper 2, the plug 2021 needs to be opened first, and then the material can be added to the feeding hopper 2 through the feeding port 202.

[0024] Furthermore, a feeding auger 6 is provided inside the feeding pipe 1. A second drive motor 7 is fixed at one end of the feeding pipe 1 away from the feeding outlet 102. The drive shaft of the second drive motor 7 is connected to the feeding auger 6. The feeding auger 6 can be rotated by the second drive motor 7, so that the feeding auger 6 can be used to transport materials.

[0025] Furthermore, a flange 103 is fixed on the feed outlet 102, which is used to connect to the feed inlet of the ball mill.

[0026] In summary, when using this device, simply open the plug 2021, add the material into the feed hopper 2 through the feeding port 202, and then start the first drive motor 4. The first drive motor 4 will drive the rotating rod 5 to rotate, causing the rotating rod 5 to drive the crushing rod to crush the material, preventing large pieces from remaining. During the crushing process, the telescopic motor 3 can be started, causing the mounting plate 301 to move up and down. This, in turn, causes the mounting plate 301 to move the rotating rod 5 up and down, thereby moving the crushing blade 501 up and down, changing the crushing height of the crushing blade 501 and improving the crushing effect. After crushing, open the discharge valve 2031 to allow the crushed material to pass through the feeding pipe 1. During this process, the telescopic motor 3 can be started again to lower the mounting plate 301, causing the rotating rod 5 to lower the conical head 502, extending the conical head 502 into the discharge port 203 to achieve the effect of material passage and prevent material blockage at the discharge port 203. Start the second drive motor 7, which drives the feeding auger 6 to rotate, so that the feeding auger 6 can deliver the material.

[0027] It is worth noting that the entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.
