[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] Reference Figure 1-5 The discharging device of the three-roller grinding machine comprises a machine body 1, a notch 2 is provided on the machine body 1, three grinding rollers 3 parallel to each other are rotatably installed between the inner walls on both sides of the notch 2, scrapers 4 are provided on the inner walls on both sides of the notch 2, the scrapers 4 are located on one side of the end grinding roller 3, a discharging plate 5 is rotatably installed on one end of the scrapers 4, a motor 6 is provided on one side of the machine body 1, a first bevel gear 7 is provided on the output end of the motor 6, a connecting shaft 8 is provided on one end of the first bevel gear 7, and a plurality of evenly distributed The cam 9 is provided, and several cams 9 are located below the discharge plate 5. A reciprocating screw 10 is rotatably installed in the inner wall of one side of the slot 2. A second bevel gear 11 is provided on one end of the reciprocating screw 10. The second bevel gear 11 is meshed with the first bevel gear 7. A reciprocating slide 12 is transmission-connected to the reciprocating screw 10. The reciprocating slide 12 is located below several grinding rollers 3 and is parallel to the grinding rollers 3. A push plate 13 is rotatably installed on the bottom end of the grinding roller 3. The bottom end of the push plate 13 contacts the inner wall of the bottom end of the slot 2.
[0023] The driving motor 6 drives the first bevel gear 7 to rotate, so that the connecting shaft 8 drives the cam 9 to perform a circular motion, thereby performing a reciprocating knock on the bottom of the discharge plate 5, so that the discharge plate 5 rotates reciprocatingly on one side of the scraper 4, thereby generating a vibration effect, effectively improving the discharge efficiency of the material and preventing it from adhering to the discharge plate 5. While the motor 6 drives the first bevel gear 7 to rotate, the second bevel gear 11 drives the reciprocating screw 10 to rotate, thereby driving the reciprocating slide 12 to perform an axial reciprocating motion, thereby driving the push plate 13 to push the material that falls under the grinding roller 3 away from the discharge plate 5, so that the material can be reused for grinding while being convenient for cleaning.
[0024] Specifically, in this embodiment, two guide plates 14 are provided on the discharge plate 5. The two guide plates 14 are tilted and symmetrically distributed with respect to each other, so as to provide lateral shielding for materials when they are discharged to prevent them from falling, and guide the materials to produce a converging effect for convenient unified collection.
[0025] Specifically, in the present embodiment, two springs 15 are provided on the bottom end of the slot 2, and a pad 16 is provided on the top end of each spring 15, and the top end of each pad 16 is in contact with the bottom end of the discharge plate 5. The springs 15 and the pad 16 provide a buffer and a limit for the sagging of the discharge plate 5 after rotation, so as to prevent the sagging angle from being too large, resulting in excessive rotation when the discharge plate 5 is struck by the cam 9, causing the material to be spilled and dropped.
[0026] Specifically, in this embodiment, a chamber 17 is opened on the inner wall of one side of the slot 2, and the two ends of the first bevel gear 7 and the second bevel gear 11 that are vertically away from each other are respectively in contact with two vertical inner walls of the chamber 17. The chamber 17 makes the meshing between the first bevel gear 7 and the second bevel gear 11 more stable.
[0027] Specifically, in this embodiment, a first slide groove 18 is opened on the inner wall of one side of the slot 2, and a T-shaped shaft 19 is rotatably installed in the inner wall of one end of the first slide groove 18. The T-shaped shaft 19 is connected to one end of the reciprocating screw 10. The T-shaped shaft 19 ensures that the reciprocating screw 10 rotates while preventing axial movement.
[0028] Specifically, in this embodiment, a second slide groove 20 is opened on the inner wall on the other side of the slot 2, and a limiting rod 21 is arranged between the inner walls at both ends of the second slide groove 20. The reciprocating slide rod 12 is slidably installed on the limiting rod 21. The limiting rod 21 makes the reciprocating movement of the reciprocating slide rod 12 smoother.
[0029] Specifically, in the present embodiment, a plurality of hinges 22 are provided on the same side of the reciprocating slide bar 12 and the push plate 13, and the hinge 22 is located on the side away from the discharge plate 5. The hinge 22 enables the push plate 13 to rotate smoothly when the reciprocating slide bar 12 drives the push plate 13 to move toward the discharge plate 5 under the influence of the material dropped from the bottom end of the slot 2, thereby preventing the push plate 13 from pushing the material toward the discharge plate 5. When the reciprocating slide bar 12 drives the push plate 13 to move away from the discharge plate 5, the top end of the push plate 13 contacts the bottom end of the reciprocating slide bar 12, and the position of the hinge 22 limits the rotation of the push plate 13, thereby enabling the push plate 13 to push the material dropped from the bottom end of the slot 2 away from the discharge plate 5.
[0030] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
