Detailed Implementation

[0029] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0030] like Figures 1-4 The illustrated mixing mill feeding device includes a lifter 5 and a storage bin 7 connected to the lifter 5. The lifter 5 is a screw conveyor with an inlet 18 at its lower end and an outlet 19 at its upper end. A sliding plate 6 is installed on the outer wall of the lifter 5, located below the outlet 19. The storage bin 7 is connected to the lifter 5 through the inlet 18. The lifter 5 transports the material from the inlet 18 at its lower end to the outlet 19 at its upper end for discharge, achieving automatic material lifting and feeding into the mixing mill. This reduces installation hazards during the feeding process and lowers the labor intensity of workers.

[0031] Specifically, the required materials are fed into the storage bin 7 in one go. The materials enter the lifter 5 from the inlet 18, are then transported by the lifter 5 to the outlet 19, and finally fall from the sliding plate 6 into the feed port of the mixer to complete the feeding of the mixer. The storage bin 7 can store a large amount of materials, eliminating the need for multiple feedings and improving production efficiency.

[0032] The present invention has a material receiving device 3 rotatably installed inside the storage compartment 7. The storage compartment 7 has an open opening for the material receiving device 3 to rotate and extend. The side of the material receiving device 3 away from the lifting device 5 always extends from the open opening, facilitating contact between the tipping bucket 2 of the transfer trolley 1 and the material receiving device 3, allowing the material receiving device 3 to be pressed down and rotated to a suitable angle for unloading. A roller 11 is rotatably installed on the upper end of the material receiving device 3 away from the lifting device 5. When the tipping bucket 2 presses down on the material receiving device 3, relative movement occurs between them. The roller 11 reduces friction, making the relative movement between the two smoother.

[0033] Specifically, one end of the tipping bucket 2 can extend into the receiving device 3 to pour materials into the receiving device 3. Simply push the transfer cart 1 to the side of the receiving device 3, and the tipping bucket 2 will automatically dock with the receiving device 3 when it flips. All the materials in the tipping bucket 2 will be poured into the storage bin 7, which is convenient to operate, reduces the labor intensity and labor costs of workers, makes feeding more convenient, eliminates the need for manual feeding, reduces labor costs, and improves production efficiency.

[0034] Gas springs 10 are symmetrically hinged to both side walls of the receiving device 3 of this utility model. The end of the gas spring 10 away from the receiving device 3 is hinged to the storage bin 7. After the tipping bucket 2 of the transfer trolley 1 is unloaded, it is retracted and gradually moves away from the receiving device 3. At this time, the gas spring 10 gradually returns to its original position and pulls the receiving device 3 to rotate and retract into the storage bin 7.

[0035] Specifically, the side of the receiving device 3 furthest from the lifting device 5 is inclined downwards along the direction of the storage bin 7. This prevents material from spilling outside the receiving device 3 during feeding, thus avoiding waste and environmental pollution. Guided by the inclined surface, all the material inside the receiving device 3 is poured into the storage bin 7.

[0036] The storage compartment 7 of this utility model includes a base 8 and two vertical baffles 4. The two vertical baffles 4 are fixed at both ends of the base 8. One side of the base 8 is connected to the lifting device 5, and the other side of the base 8 is hinged to the receiving device 3. The receiving device 3 can rotate between the two vertical baffles 4. The end of the gas spring 10 away from the receiving device 3 is hinged to the vertical baffle 4.

[0037] Specifically, the vertical baffle 4 can block the material and guide it into the base 8, preventing material from splashing outside the device and causing waste during the feeding process. At the same time, it can also play a certain guiding role in the rotation of the feeder 3.

[0038] Specifically, the base 8 is provided with a storage chamber 17, which is connected to the inlet 18. The storage chamber 17 is surrounded by several ramps 16 that slope downwards along the inlet 18, which guide the material box inlet 18 to facilitate feeding by the lifter 5.

[0039] The material receiving device 3 of this utility model includes a guide plate 13 and two side plates 12. The two side plates 12 are respectively fixed on both sides of the guide plate 13. When the material receiving device 3 rotates, the side plates 12 can slide with the vertical baffle 4 to play a certain guiding role and prevent shaking. In addition, the side plates 12 can also block the two sides of the protruding part of the material receiving device 3 during feeding to prevent material splashing and guide the material.

[0040] The two ends of the roller 11 of this utility model are rotatably mounted on the two side plates 12, and a connecting plate 14 is installed between the two side plates 12. The connecting plate 14 is inclined downward along the direction of the feeder 5, which plays a certain role in guiding the material. The connecting plate 14 is connected to the lower end of the guide plate 13, and the lower end surface of the connecting plate 14 is hinged to the upper end surface of the base 8 through the hinge seat 15. The connecting plate 14 can also block the material during feeding to prevent the material from getting stuck at the hinge seat 15 and affecting the rotation of the feeder 3.

[0041] Specifically, the lower end face of the side plate 12 can abut against the upper end face of the base. The side of the base 8 away from the lifter 5 is provided with a stop block 9 that can limit the rotation of the receiver 3. Both the side plate 12 and the stop block 9 can limit the rotation of the receiver 3, so that the movement angle of the receiver 3 is limited to a certain area, and the material inside the receiver 3 is prevented from spilling.

[0042] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
