It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, only for conveniently and clearly assisting in explaining the purpose of the embodiments of the present utility model. The same or similar reference numerals in the drawings represent the same or similar components.

[0029] A feeding structure for a square cone mixer, as Figures 1 to 11 shown, includes a storage bin 1 (supported by a bracket) and a discharge pipe 2 connected to the bottom of the storage bin 1. The bottom of the discharge pipe 2 is rotatably connected with a connecting pipe 3. The bottom of the connecting pipe 3 is sequentially connected with a storage pipe 4 and a blanking pipe 5. The connecting pipe 3, the storage pipe 4, and the blanking pipe 5 are in a Z shape, and the sum of the spaces in the connecting pipe 3, the storage pipe 4, and the blanking pipe 5 is a blanking cavity. The bottom of the discharge pipe 2 is provided with a first opening and closing structure for controlling the opening and closing of the discharge pipe 2, and the bottom of the blanking pipe 5 is provided with a second opening and closing structure for controlling the opening and closing of the blanking pipe 5.

[0030] The first opening and closing structure includes a first disc body 6 horizontally arranged on the inner wall of the discharge pipe 2. Two first hole bodies 7 are formed in the first disc body 6. A second disc body 8 is horizontally arranged at the top of the connecting pipe 3. The top of the second disc body 8 is movably attached to the bottom of the first disc body 6. Two second hole bodies 9 are formed in the second disc body 8. When the bottom of the blanking pipe 5 is above the feeding port of a mixing square cone, the projection of the first hole body 7 in the vertical direction is within the projection of the second disc body 8 in the vertical direction, and the first hole body 7 and the second hole body 9 are in a misaligned state. When the bottom of the blanking pipe 5 is at the side of the feeding port, the first hole body 7 communicates with the second hole body 9.

[0031] An L-shaped passive member 10 is arranged on the outer wall of the connecting pipe 3. The bottom of the passive member 10 is connected to the outer wall of the connecting pipe 3, and the top is vertically and movably attached to the outer wall of the discharge pipe 2. A first stopping portion 11 and a second stopping portion 12 are arranged on the outer wall of the discharge pipe 2. The passive member 10 is located between the first stopping portion 11 and the second stopping portion 12. When the passive member 10 abuts against the first stopping portion 11 and the second stopping portion 12 respectively, the discharge pipe 2 is in an open state and a closed state respectively.

[0032] The bottom of the blanking pipe 5 is provided with a trumpet-shaped transition portion 13 that is larger at the top and smaller at the bottom. The bottom of the transition portion 13 is provided with a cylindrical blanking portion 14. The diameter of the blanking portion 14 is smaller than the diameter of the feeding port. The second opening and closing structure includes a closing plate 15 hinged to the bottom of the blanking portion 14. A positioning mechanism for positioning the free end of the closing plate 15 is arranged on the blanking portion 14.

[0033] The positioning mechanism includes a locking column 16 vertically and rotatably arranged on the outer wall of the blanking portion 14. A locking portion 17 is horizontally arranged on the side of the locking column 16. A U-shaped positioning portion 18 is horizontally arranged at the free end of the closing plate 15. When the free end of the locking portion 17 faces away from the blanking portion 14, rotating the closing plate 15 upward can make the locking column 16 and the locking portion 17 pass through the opening of the positioning portion 18. When the closing plate 15 is attached to the bottom of the blanking portion 14, rotating the locking portion 17 can make the upper side of the locking portion 17 fit against the lower side of the closing plate 15.

[0034] A third stopping portion 19 is arranged at the bottom of the closing plate 15. When the closing plate 15 closes the blanking portion 14, the side of the locking portion 17 abuts against the third stopping portion 19.

[0035] A horizontally arranged L-shaped operating handle 20 is provided at the bottom of the locking column 16, and the projection of the free end of the operating handle 20 in the vertical direction is located at the side of the projection of the blanking part 14 in the vertical direction.

[0036] A fourth termination part 21 is vertically arranged on the outer wall of the blanking pipe 5. When the locking part 17 abuts against the fourth termination part 21, the opening and closing plate 15 is in a state of opening the blanking part 14.

[0037] The storage pipe 4 is in an inclined state, and the top of the storage pipe 4 is connected to the connecting pipe 3.

[0038] An annular elastic band is wound around the outer wall of the storage pipe 4, and a vibrating ball is arranged on the elastic band. The vibrating ball is made of elastic material.

[0039] The feeding structure for the square cone mixer provided by the present utility model, before feeding into the mixing square cone, first there is an amount for feeding in the blanking cavity, that is, the materials in the connecting pipe 3, the storage pipe 4 and the blanking pipe 5 are the materials fed into the mixing square cone at one time. Then the worker manually rotates the connecting pipe 3, the storage pipe 4 and the blanking pipe 5, and makes the blanking pipe 5 located above the feeding port. After that, the lid at the feeding port is opened, and the bottom of the blanking pipe 5 is opened. In this way, the materials in the blanking cavity can naturally slide into the mixing square cone; then the bottom of the blanking pipe 5 is closed, and the blanking pipe 5, the storage pipe 4 and the connecting pipe 3 are manually rotated outwards, so that the blanking pipe 5, the storage pipe 4, etc. are all located at the side of the mixing square cone. In this way, when the mixing square cone rotates, it will not interact with the blanking pipe 5, etc. When the blanking pipe 5, etc. move to the side above the mixing square cone, the first opening and closing structure is opened, so that the materials in the material bin 1 naturally slide into the blanking cavity and wait for the next feeding.

[0040] During actual use, first when the connecting pipe 3 and the storage pipe 4 are on standby, at this time the passive part 10 abuts against the first termination part 11, and the first hole body 7 and the second hole body 9 are in a communicating state. Therefore, the materials in the material bin 1 can automatically slide into the blanking cavity; then when materials need to be added into the mixing square cone (at this time the feeding port of the mixing square cone is located above, and the blanking pipe 5 can be normally moved above the feeding port), the worker directly rotates the blanking pipe 5 until the passive part 10 abuts against the second termination part 12;

[0041] At this time, the first hole body 7 and the second hole body 9 are in a misaligned state, and the materials in the material bin 1 cannot directly enter the blanking cavity. Then the worker rotates the operating handle 20 outwards. The operating handle 20 drives the locking column 16 to rotate, and makes the locking part 17 rotate to abut against the fourth termination part 21. At this time, the locking part 17 does not support the opening and closing plate 15. At the same time, the opening and closing plate 15 rotates downwards under the action of gravity and the pressure of the materials, thereby opening the blanking part 14. At the same time, the opening and closing plate 15 maintains a vertical state, which can block the materials and prevent the materials from flushing to the outside.

[0042] During the sliding process of the materials, since the storage pipe 4 is in an inclined state, the materials can slide down smoothly. At the same time, during the sliding process of the materials, the worker can also pull the vibrating ball outwards and then release it. By hitting the storage pipe 4 with the vibrating ball, the falling of the materials can be accelerated and the residue can be reduced.

[0043] After all the materials in the blanking cavity slide into the mixing square cone, the worker rotates the opening and closing plate 15 upwards. At this time, the opening of the positioning part 18 can cross over the locking column 16 and pass through the locking part 17 until the opening and closing plate 15 fits against the bottom of the blanking part 14. Then rotate the operating handle 20 until the locking part 17 abuts against the third termination part 19. At this time, the top of the locking part 17 also fits against the lower side of the opening and closing plate 15, so that the opening and closing plate 15 can be supported and limited.

[0044] Then the worker rotates the blanking pipe 5 outwards until the blanking pipe 5 moves to the side of the mixing square cone. At this time, the mixing square cone can rotate normally. After the blanking pipe 5 rotates to the outside, the materials in the material bin 1 can automatically fall into the blanking cavity, which is simple and convenient.

[0045] The above description is only a description of the preferred embodiment of the present invention, and does not limit the scope of the present invention in any way. Any changes and modifications made by those of ordinary skill in the field of the present invention according to the above disclosure are within the protection scope of the claims.
