[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0016] An automatic feeder for a grinding mill, combined with Figure 1 to Figure 2 As shown, the sampling port 2 is provided on the side wall of the material discharge channel 1 of the mill, the sampling port 2 is connected with a tee 3, the tee 3 is horizontally arranged and a motor 4 is arranged at a port away from the sampling port 2, and the output shaft of the motor 4 penetrates the tee 3 and is connected with a spiral sampler. The spiral sampler is horizontally arranged inside the tee 3 and extends into the material discharge channel 1. The spiral sampler rotates under the drive of the motor 4, so as to take out the material falling in the material discharge channel 1. The spiral sampler is a prior art, and its structure and working principle are not described here.

[0017] The port between the sampling port 2 and the motor 4 on the tee 3 is arranged downward and connected to a pipe 5, which is arranged longitudinally and used to drop the material taken out by the spiral sampler. A sampling bucket 10 is arranged below the pipe 5, and the sampling bucket 10 is used to contain the material falling in the pipe 5.

[0018] The bottom end of the pipe 5 is provided with an upper cover plate 6, and a material drop opening communicating with the pipe 5 is provided on the upper cover plate 6. A plurality of guide rods 7 are evenly arranged along the circumference of the edge of the upper cover plate 6, which can be specifically as follows: Figure 1 to Figure 2 As shown in the figure, the guide rods 7 are arranged vertically downward and a lower supporting plate 8 is arranged at the bottom end, and the lower supporting plate 8 is arranged opposite to the upper cover plate 6.

[0019] A sliding support plate 9 is slidably mounted on the guide rod 7. The sliding support plate 9 is horizontally arranged and used to place the sampling bucket 10. In order to ensure the stability of the sampling bucket 10 during the sampling process and to prevent the material dust from spilling out, and to facilitate the removal of the sampling bucket 10 after sampling, a locking mechanism is provided on the lower support plate 8. The locking mechanism is used to drive the sliding support plate 9 to move up and down, so that the top of the sampling bucket 10 is close to and away from the upper cover plate 6. When sampling, the locking mechanism drives the sliding support plate 9 to move up, and the top of the sampling bucket 10 abuts against the upper cover plate 6. The sampling bucket 10 is clamped by the sliding support plate 9 and the upper cover plate 6 to ensure the stability of the sampling bucket 10 during the sampling process and to prevent the sample dust from spilling out; when the sampling is completed, the locking mechanism drives the sliding support plate 9 to move down, and the top of the sampling bucket 10 is away from the upper cover plate 6, so that the sampling bucket 10 is conveniently removed.

[0020] Specifically, the locking mechanism includes a support 11 arranged at intervals on the lower support plate 8, and a horizontally arranged rotating shaft 12 is arranged on the support 11, and the rotating shaft 12 is rotatably connected to the support 11. A cam 13 is arranged on the rotating shaft 12, and two cams 13 are evenly arranged below the sliding support plate 9. One end of the rotating shaft 12 is connected to a handle 14, and the handle 14 is used to drive the rotating shaft 12 to rotate, thereby rotating the cam 13, and the cam 13 rotates to drive the sliding support plate 9 to move up and down.

[0021] When the utility model is used, when sampling, the rotating shaft 12 is first rotated by the handle 14 to make the cam 13 on the rotating shaft 12 stand up, so that the sliding support plate 9 moves up, and the top of the sampling barrel 10 abuts against the upper cover plate 6, such as Figure 1 Then start the motor 4 to drive the spiral sampler to take the material, and the taken material falls into the sampling barrel 10 through the pipe 5 connected to the tee 3.

[0022] When the material is taken, the motor 4 is turned off first; then the shaft 12 is rotated by the handle 14, so that the cam 13 on the shaft 12 falls down, so that the sliding support plate 9 moves down, and the top of the sampling barrel 10 is away from the upper cover plate 6, such as Figure 2 As shown, the sampling barrel 10 is removed.

[0023] The utility model can realize automatic material taking by means of the motor 4 and the spiral sampler, and can also control the material taking speed by controlling the rotation speed of the motor 4; the upper cover plate 6, the guide rod 7, the lower support plate 8, the sliding support plate 9 and the locking mechanism can not only ensure the stability of the sampling barrel 10 during the sampling process and avoid the dust of the material from overflowing, but also can conveniently remove the sampling barrel 10 after sampling.
