Detailed Implementation

[0012] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 The present invention will be described in further detail below.

[0013] Embodiment 1 of this utility model Reference Figures 1-4This utility model discloses a ball-adding auxiliary device, including a cylinder 1 and a support frame 2. The top of the cylinder 1 is a conical flare for easy receiving of steel balls. The middle part of the cylinder 1 is cylindrical, and the bottom of the cylinder 1 is a conical constriction for easy centralized unloading. The support frame 2 is welded to the outer wall of the middle part of the cylinder 1. The cylinder 1 is 2m high and has a diameter of 1.5m at the middle part.

[0014] An electromagnetic crane 3 is installed above the cylinder 1 to lift steel balls from the ball pool into the cylinder 1. The electromagnetic crane 3 places the steel balls into the conical flared opening at the top of the cylinder 1. The cylinder 1 is made of wear-resistant steel, and the diameter of the top opening is slightly larger than the diameter of the suction cup of the electromagnetic crane 3, ensuring that all the steel balls released by the electromagnetic crane 3 fall into the cylinder 1. A rubber buffer layer with a thickness of 5mm is fixed inside the cylinder 1 to reduce the impact and noise when the steel balls fall.

[0015] A bottom chute 4, 2m long and U-shaped in cross-section (0.5m wide and 0.3m deep), is fixed at the bottom of the cylinder 1. The bottom chute 4 is connected to the interior of the cylinder 1, and a cover plate 5 is installed at the end of the bottom chute 4 furthest from the cylinder 1. The bottom chute 4 forms a 30-degree angle with the ground. The inner wall of the bottom chute 4 is polished smooth to ensure that the steel ball can fall naturally under gravity.

[0016] A rotating shaft 51 is welded and fixed to one side of the cover plate 5, and mounting blocks 41 are fixed to both side walls of the bottom chute 4. The rotating shaft 51 is rotatably connected to the mounting blocks 41. The cover plate 5 can rotate along the axis of the rotating shaft 51, thereby opening the discharge port of the bottom chute 4, and the steel balls in the cylinder 1 are discharged from the chute opening of the bottom chute 4.

[0017] A connecting plate 42 is fixed above the bottom chute 4 near the top of the cover plate 5. A locking assembly 6 is provided between the connecting plate 42 and the mounting plate 61 to secure the cover plate 5 when it is closed. The locking assembly 6 includes a mounting plate 61, which is fixed to the connecting plate 42. The mounting plate 61 has a mounting groove 62, in which a trapezoidal baffle 63 is inserted. The baffle 63 contacts the top side wall of the cover plate 5 to prevent the cover plate 5 from opening. A clearance groove 52 is provided at the top of the cover plate 5, through which one end of the mounting plate 61 passes. The clearance groove 52 allows the cover plate 5 to rotate smoothly. After the baffle 63 is removed, the cover plate 5 can rotate along the pivot 51, thereby opening the bottom chute 4 and allowing the steel balls in the cylinder 1 to flow out. A chain (not shown in the figure) is fixed between the tail of the baffle 63 and the side wall of the bottom chute 4, making the baffle 63 easier to find and less likely to be lost after it is pulled out of the mounting slot 62. After the cover plate 5 is opened, the baffle 63 is inserted into the mounting slot 62, so that the baffle 63 presses down on the cover plate 5, ensuring that the cover plate 5 is always in the open state.

[0018] Below the outlet of the bottom chute 4, there is a ball feeding hopper 7. The steel balls in the cylinder 1 fall into the ball feeding hopper 7 after passing through the bottom chute 4. Then, the staff sends the steel balls in the feeding hopper into the ball mill equipment.

[0019] The implementation principle of the ball-adding auxiliary device in Embodiment 1 of this utility model is as follows: When steel balls need to be added to the ball mill, the steel balls are first transferred by using an electromagnetic crane 3 to pick up the bulk steel balls. The electromagnetic crane 3 is then moved to a position directly above the cylinder 1, ensuring that the entire working range of the electromagnetic crane 3 is located above the inner ring of the cylinder 1. Afterwards, the electromagnetic crane 3 is demagnetized, and the steel balls fall into the cylinder 1 under gravity, completing the temporary storage.

[0020] Then, the ball-filling hopper 7 is fed. When the ball-filling hopper 7 needs to be filled, the operator pulls out the baffle 63, rotates the cover plate 5 to open the slot, and the steel balls in the cylinder 1 slide into the slot through the bottom chute 4 and flow into the ball-filling hopper 7. When the ball-filling hopper 7 is full, the operator rotates the cover plate 5 to close the slot, inserts the baffle 63 into the installation slot 62 and knocks it to fix it to prevent the steel balls from leaking out.

[0021] This utility model's ball-adding auxiliary equipment features mechanized transport, reducing labor costs: The electromagnetic crane 3, in conjunction with the facility, replaces manual handling, reducing labor consumption and intensity; it eliminates safety hazards: avoiding the risks of rolling or crushing during manual handling of steel balls, improving operational safety; it increases feeding efficiency: the time for feeding the ball-adding hopper 7 is reduced by 80% compared to manual feeding; the cylinder 1 can temporarily store steel balls, and the bottom chute 4 and controllable cover 5 quickly feed the ball-adding hopper 7, adapting to continuous production needs; it has a stable structure and strong adaptability: using wear-resistant materials and a reasonable tilt angle ensures the durability of the facility and allows it to adapt to different specifications of ball-adding hoppers 7.

[0022] Embodiment 2 of this utility model Reference Figure 5 and Figure 6 The difference from Embodiment 1 is that the locking assembly 6 includes a fixing block 64 and a locking bolt 65. The locking bolt 65 passes through the fixing block 64 and is threadedly connected to it. When the cover plate 5 is closed, the end of the locking bolt 65 near the cover plate 5 abuts against the top of the cover plate 5, thereby fixing the cover plate 5 and blocking the outlet of the chute 4 at the bottom of the cover plate 5. When it is necessary to open the cover plate 5, the locking bolt 65 is loosened, causing it to move away from the cover plate 5. After opening the cover plate 5, the locking bolt 65 is loosened again, causing it to move closer to the cover plate 5, so that the top of the cover plate 5 abuts against the locking bolt 65, keeping the cover plate 5 in an open state to facilitate the falling of the steel ball.

[0023] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
