DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail. It should be understood that the specific embodiments described herein are only used to explain the utility model, and are not used to limit the utility model.

[0026] Embodiment:

[0027] Referring to Figures 1-7 The utility model aims at providing a kind of direct connection drive type pin bar mill, including supporting plate 1, the top of supporting plate 1 is equipped with driving motor 2 and sealing shell 3, rotating disc 4 and stationary disc 5 are installed in sealing shell 3, sealing shell 3 side wall is provided with discharge port 6, rotating disc 4 and stationary disc 5 are oppositely arranged, the power end of driving motor 2 is connected with rotating disc 4 power, sealing shell 3 is equipped with feeding hopper 7 at the end away from driving motor 2, and discharging pipeline 8 is installed between feeding hopper 7 and sealing shell 3;Rotating disc 4 is equipped with a plurality of first grinding rods 9 at one end towards stationary disc 5, and stationary disc 5 is equipped with a plurality of second grinding rods 10 at one end towards rotating disc 4, and first grinding rod 9 and second grinding rod 10 cooperate with each other.

[0028] The working principle of the scheme is as follows: first, the material is sent to the feeding hopper 7, and then the material enters the sealing shell 3 along the discharging pipeline 8. At the same time, the driving motor 2 is started, and the power end of the driving motor 2 is directly connected with the rotating disc 4 through the sealing shell 3. Under the driving of the driving motor 2, the rotating disc 4 starts to rotate, and the first grinding rod 9 on the rotating disc 4 also rotates. At this time, the material entering the sealing shell 3 will reach between the rotating disc 4 and the stationary disc 5, and the material will collide with the first grinding rod 9. In this process, the material is continuously broken, and the broken material will randomly fly in all directions, and then the flying material will collide with the first grinding rod 9 or the second grinding rod 10 again until the particle size of the material meets the requirements, and the material will pass through the gap between the first grinding rod 9 and the second grinding rod 10 and be discharged through the discharge port 6.

[0029] This design uses a direct-drive motor to rotate the rotating disk 4. Compared to the traditional belt drive, this design has the following advantages: First, the direct connection between the drive motor 2 and the rotating disk 4 ensures that the rotation axis of the drive motor 2 coincides with the axis of the rotating disk 4, guaranteeing that the rotating disk 4 will not be eccentric during rotation and is more stable. Second, the entire device operates with less vibration and noise. Third, the structure is more compact, requiring less floor space. Fourth, installation is more convenient.

[0030] To facilitate the rotation of the rotating disk 4 by the drive motor 2, a bearing sleeve 11 is provided between the drive motor 2 and the rotating disk 4, and a support frame 12 is provided between the bearing sleeve 11 and the support plate 1.

[0031] Since the length of the power end of the drive motor 2 is limited, a coupling 13 is provided between the bearing sleeve 11 and the drive motor 2 to facilitate direct connection between the drive motor 2 and the rotating disk 4.

[0032] To facilitate the introduction of material from the discharge pipe 8 between the stationary disk 5 and the rotating disk 4, the stationary disk 5 includes a feed hole 14, and the end of the discharge pipe 8 away from the feed hopper 7 is connected to the feed hole 14.

[0033] After the material reaches the area between the rotating disk 4 and the stationary disk 5, it will fall naturally due to gravity. This makes it impossible to achieve uniform distribution of the material during grinding. To avoid this problem, such as... Figure 3 , Figure 5 As shown, a material distribution platform 15 is installed at the end of the rotating disk 4 facing the stationary disk 5. The material distribution platform 15 is conical, and its axis coincides with the axis of the rotating disk 4. Several first grinding rods 9 are arranged around the material distribution platform 15. The material distribution platform 15 will throw a portion of the received material to the surrounding area, so that the material can be evenly distributed to the greatest extent.

[0034] To ensure that the material is evenly thrown to all sides, several fan blades 16 are installed on the side wall of the distribution platform 15. The length direction of the fan blades 16 is the same as the length direction of the distribution platform 15. When the material falls into the gap between adjacent fan blades 16, some of the material will be thrown directly to all sides, while some of the material will move along the length direction of the gap and be thrown to all sides during the movement.

[0035] Preferably, the fan blade 16 is an S-shaped fan blade 16.

[0036] During the grinding process, some material will move towards the rotating disk 4 or the stationary disk 5. At this time, some material will reach the gap between the first grinding rod 9 and the stationary disk 5, where it will be crushed by the compression between the first grinding rod 9 and the stationary disk 5. Figures 3-7As shown in the drawings, in order to increase the extrusion area, a plurality of first grinding rods 9 are arranged in a plurality of annular arrays, the annular arrays are arranged around the distribution table 15, and the one end of the stationary disc 5 towards the rotating disc 4 is provided with a plurality of first grinding grooves 17, and the annular arrays are arranged opposite to the first grinding grooves 17.

[0037] In order to further increase the extrusion area, the first grinding rod 9 comprises a fixed segment 18 and a grinding segment 19, one end of the fixed segment 18 is connected with the rotating disc 4, the other end of the fixed segment 18 is connected with the grinding segment 19, part of the area of the grinding segment 19 is located in the first grinding groove 17, and a gap is arranged between the grinding segment 19 and the inner wall of the first grinding groove 17. The design makes the top and part of the side wall of the grinding segment 19 can cooperate with the first grinding groove 17 to extrude the material and further crush it.

[0038] Preferably, the grinding segment 19 is part of a sphere, and the inner wall of the first grinding groove 17 is arc-shaped.

[0039] In order to make the material more easily broken after colliding with the fixed segment 18, a plurality of grooves 20 are arranged on the side wall of the fixed segment 18. The plurality of grooves 20 make the fixed segment 18 uneven, and the uneven fixed segment 18 makes the material more easily broken when colliding with the fixed segment 18.

[0040] In the scheme, the second grinding rod 10 is the same in structure as the first grinding rod 9.

[0041] Similarly, a plurality of second grinding rods 10 are arranged in a plurality of circular ring arrays, the circular ring arrays are arranged around the feeding port, the one end of the rotating disc 4 towards the stationary disc 5 is provided with a plurality of second grinding grooves 21, the second grinding grooves 21 are arranged opposite to the circular ring arrays, part of the area of the top of the second grinding rod 10 is located in the second grinding groove 21, and there is a gap between the second grinding rod 10 and the second grinding groove 21.

[0042] In summary, the scheme has the following advantages: first, the driving motor 2 is directly connected with the rotating disc 4, the rotation axis of the driving motor 2 power end coincides with the axis of the rotating disc 4, which ensures that the rotating disc 4 will not be eccentric when rotating, and is more stable. Second, the whole device runs with smaller vibration and noise. Third, the structure is more compact, and the occupied area is smaller. Fourth, under the cooperation of the first grinding rod 9 and the first grinding groove 17, the material can be broken to the maximum extent, and the particle size of the broken material is smaller.

[0043] Of course, the present application can also have other various embodiments, and those skilled in the art can make various corresponding changes and modifications according to the present application without departing from the spirit and essence of the present application, but these corresponding changes and modifications should belong to the protection scope of the claims attached to the present application.
