DETAILED DESCRIPTION

[0016] The technical scheme of the utility model discloses is relatedly explained below in combination with the drawings and implementation method.

[0017] As Figure 1 And 2 Shown, an automatic steel ball adding device suitable for concentrator, including steel ball bin 8, a plurality of steel balls 9 are placed in steel ball bin 8;Steel ball bin 8 both sides are equipped with guide rail 1, and the bottom four corners are all equipped with weighing module 13, and the weighing module 13 adopts existing weight sensor, so the weighing principle is not repeated.

[0018] The upper portion of guide rail 1 is equipped with a plurality of support legs 3 arranged symmetrically, and the bottom of support leg 3 is equipped with walking wheel 2, which is in sliding connection with guide rail 1;Between the two support legs 3 arranged symmetrically, there is crossbeam 4, and hoist 7 and fixed pulley 5 are arranged between adjacent crossbeams 4, electromagnet 6 is arranged below fixed pulley 5, and the rope body of hoist 7 is connected with electromagnet 6 after passing through fixed pulley 5.

[0019] The upper portion of any one support leg 3 is equipped with motor 10, and the side of motor 10 is equipped with first belt pulley 11, and the outer side of walking wheel 2 below this support leg 3 is equipped with second belt pulley 12, and first belt pulley 11 and second belt pulley 12 are connected by belt transmission.

[0020] The embodiment also includes a control system, which is signal connected with electromagnet 6, hoist 7, motor 10 and weighing module 13, and since the control system adopts existing control equipment, the control principle is not repeated.

[0021] The use process of the utility model is as follows:

[0022] In the initial state, the steel ball bin 8 is filled with steel balls 9, the electromagnet 6 is in the initial position, and the weighing module 13 can accurately weigh the steel balls 9 in the steel ball bin 8. When the set ball mass is added, when the steel balls 9 need to be added, the motor 10 is started, the second pulley 12 is driven by the first pulley 11, the walking wheel 2 is driven by the second pulley 12, the corresponding supporting leg 3 moves in the guide rail 1, and stops when reaching the specified position;

[0023] Then, the winch 7 is started, the electromagnet 6 is lowered into the steel ball bin 8, a certain amount of steel balls 9 can be adsorbed after the electromagnet 6 is powered on, the mass in the steel ball bin 8 decreases after the electromagnet 6 is lifted by the winch 7, and the weighing module 13 can transmit data to the control system for personnel observation; When the steel balls 9 are lifted, the electromagnet 6 always maintains the magnetic force, the motor 10 is started again, the supporting leg 3 drives to continue to move along the guide rail 1, and when the specified position, i.e. the ball mill ball adding port 14, is reached, the winch 7 lowers the electromagnet 6 to the same level of the ball mill ball adding port 14, the electromagnet 6 is powered off, the steel balls 9 are released, and thus one ball adding operation is completed.

[0024] In addition, the steel ball bin 8 can be arranged in multiple quantities along the guide rail 1, and different specifications and sizes of steel balls are arranged in the steel ball bin 8 to realize precise addition of different proportions.
