[0029] The present invention is described in detail below with reference to the accompanying drawings and embodiments:

[0030] See also Figure 1-9The existing wheel mill includes a mixing drum 1, and a feeding port 2 is provided on the lower end surface of the mixing drum 1; the feeding port device of the wheel mill described in the utility model includes two rotating blades 3 rotatably arranged on the lower end surface of the mixing drum 1, and the upper end surfaces of the two rotating blades 3 are in contact with the lower end surface of the mixing drum 1. Back plates 4 are fixedly arranged on the sides of the two rotating blades 3, and the upper end surface of each back plate 4 is in contact with the lower end surface of the mixing drum 1. The outer side surfaces of the two rotating blades 3 are inclined surfaces, and the angle space between the two rotating blades 3 forms a feeding channel of the feeding port 2. The size of the feeding channel can be adjusted by rotating the two rotating blades 3 according to the size of the receiving bag mouth, and the rotating blades 3 have a damping effect when rotating.

[0031] In this embodiment, the rear ends of the two rotating blades 3 are hinged to each other, and the top ends of the hinge shafts 5 of the rotating blades 3 are fixedly arranged on the lower end surface of the mixing drum 1; when the two rotating blades 3 are completely closed below the discharge port 2, the discharge port 2 can be closed in cooperation with the back plate 4, so that the two rotating blades 3 have the function of discharge while also having the function of closing the discharge port 2. When taking away the receiving bag filled with materials, the two rotating blades 3 can be completely closed below the discharge port 2, and the discharge port 2 can be closed in cooperation with the back plate 4 to avoid waste of materials.

[0032] In order to achieve a linkage effect when the two rotating blades 3 rotate, in this embodiment, a guide device is provided on the rear side of the rotating blade 3, and the guide device is used to drive the other rotating blade 3 to rotate in a synchronous direction when any rotating blade 3 rotates.

[0033] In this embodiment, the guide device includes two arc strips 6 of different diameters arranged at the rear side of the rotating blade 3, the center lines of the two arc strips 6 coincide with the central axis of the hinge shaft 5, and the annular space between the two arc strips 6 is provided with a fixed shaft 7 whose top end is rotatably connected to the lower end surface of the mixing drum 1, and two gears are fixedly arranged on the outer surface of the fixed shaft 7, the diameter of the upper large gear 8 is larger than the diameter of the lower small gear 9, the large gear 8 meshes with the teeth provided on the inner side wall of the outer arc strip 6, and the small gear 9 meshes with the teeth provided on the outer surface of the inner arc strip 6; the diameter design of the large gear 8 and the small gear 9 meets the requirement that the inner arc strip 6 and the outer arc strip 6 have the same angular velocity. That is, when any one of the large gear 8 and the small gear 9 drives the fixed shaft 7 to rotate, the inner arc strip 6 and the outer arc strip 6 have the same angular velocity.

[0034] When in use, by pushing any one of the rotating blades 3 to rotate, the cooperation of the outer arc strip 6, the inner arc strip 6, the large gear 8 and the small gear 9 can drive the other rotating blade 3 to rotate synchronously in the opposite direction. During production, it is not necessary to adjust the two rotating blades 3 at the same time. Only one of the rotating blades 3 needs to be adjusted to achieve the synchronous reverse linkage of the other rotating blade 3, so that the angle between the two rotating blades 3 becomes smaller or larger to adapt to the receiving bag openings of different sizes.

[0035] In order to facilitate the purpose of pushing the rotating blade 3 to rotate, in this embodiment, a sleeve 10 is fixedly provided at the joint of the rotating blade 3 and the back plate 4, and an inner rod 11 is sleeved inside the sleeve 10; the front end of each arc-shaped bar 6 is fixedly provided with the corresponding sleeve 10; when in use, the inner rod 11 is pulled out, and the rotation of the rotating blade 3 can be conveniently pushed through the inner rod 11.

[0038] The working principle of the utility model is as follows: when in use, the inner rod 11 is partially pulled out from the sleeve 10, and the inner rod 11 is manually pushed to drive the rotating blade 3 to rotate, and the rotating blade 3 drives the back plate 4 to move. Through the cooperation of the inner arc strip 6 and the outer arc strip 6 with the large gear 8 and the small gear 9, one of the rotating blades 3 is rotated, and the other rotating blade 3 rotates synchronously in the opposite direction, so as to achieve the purpose of adjusting the angle between the two rotating blades 3 according to the size of the receiving bag opening.
