Example 1

As shown in fig. 2, a limestone warehousing device comprises a proportioning bin 1, a first conveyer belt 2 arranged on the proportioning bin 1; a plurality of second conveying belts 3 arranged below the proportioning bins 1; the first conveyor 2 is used to transport the material from the silo. The second conveyer belt 3 is used for evenly conveying the materials in the proportioning bin 1 to the two raw material mills respectively.

Specifically, as shown in 2,3, a three-way material distributing assembly is arranged at the top in the batching bin 1, two material distributing bins 4 are arranged at the bottom in the batching bin 1, and a material outlet is arranged at the bottom of each material distributing bin 4; the first conveying belt 2 is arranged at the top of the three-way material distributing assembly; a plurality of second conveyer belts 3 one-to-one correspond the discharge gate setting.

The three-way distribution component is used for uniformly conveying the raw materials on one conveying belt into two distribution bins 4 for accumulation and then conveying the raw materials through a second conveying belt 3, and in other embodiments, the three-way distribution component can be realized by adopting the existing three-way distribution component on the market, but the existing three-way distribution component adopts a motor to drive a distribution valve to play a role in division, and the three-way distribution component is not suitable for equipment for large materials such as limestone; in this embodiment, as shown in fig. 3, the three-way material distributing assembly includes: the three-way distributing assembly comprises an inverted Y-shaped three-way distributing bin 5, the three-way distributing bin 5 comprises a feeding hole 51, a first discharging hole 52 and a second discharging hole 53, a rotating shaft 7 is arranged at the joint of the first discharging hole 52 and the second discharging hole 53, a baffle 6 is arranged on the rotating shaft 7, the other end of the baffle 6 is arranged in the feeding hole 51, the first discharging hole 52 or the second discharging hole 53 is respectively blocked by the baffle 6, so that the first discharging hole 52 and the feeding hole 51 or the second discharging hole 53 and the feeding hole 51 are communicated, and the first discharging hole 52 and the second discharging hole 53 are distributed and aligned with different distributing bins 4; a driving component 8 is further arranged outside the proportioning bin 1, the driving component 8 is connected with the rotating shaft 7, and the baffle 6 swings in the feeding hole 51 by taking the rotating shaft 7 as an axis; in the existing equipment, a motor is mostly adopted to complete driving, if the motor is adopted, a servo motor is required to control the rotation angle and the forward and reverse rotation of the motor, and meanwhile, the weight of limestone is large, so that large impact force is generated, the influence on the servo motor is large, and the service life of the motor is greatly shortened; the cost of the servo motor is higher, so the economic benefit of the existing technical scheme is lower; therefore, in this embodiment, the following technical solutions are adopted to implement: as shown in fig. 4, one end of the rotating shaft 7 extends out of the proportioning bin 1; the drive assembly 8 includes: a connecting rod 81 and an electric telescopic rod 83; one end of the connecting rod 81 is fixedly connected with one end of the rotating shaft 7 extending out of the proportioning bin 1; the moving end of the electric telescopic rod 83 is hinged with a sliding sleeve 82, and the sliding sleeve 82 is sleeved on the connecting rod 81; the fixed end of the electric telescopic rod 83 is fixedly arranged and can be fixed on the proportioning bin 1; through the motion of control electric telescopic handle 83 to control sliding sleeve 82 slides on connecting rod 81, therefore connecting rod 81 can take place the swing, thereby drives the pivot 7 rotatory, realizes the rotation of control baffle 6, thereby realizes evenly dividing the material in dividing the feed bin 4. In the present embodiment, the two sides of the baffle 6 are further provided with a backing plate 61, and the backing plate 61 is connected with the baffle 6 through a spring 62; the backing plate 61 is arranged to increase the weight of limestone, increase the particle size and increase the impact energy, so that the front and back surfaces of the baffle 6 are impacted to a certain extent in the repeated swinging motion, resulting in damage; therefore, in order to relieve the impact, a structure that the backing plate 61 is matched with the spring 62 is adopted; it should be emphasized that only one end of the shutter 6 is in contact with the inner wall of the feed opening 51 during the swinging motion of the shutter 6, and the pad 61 should not be in contact therewith.

Finally, it should be emphasized that, in the present embodiment, for the explanation of the main points of the invention, the prior art is adopted for the structures not mentioned, such as the material, the fixing of the first conveyor belt 2, the fixing of the second conveyor belt 3, and so on; of course, the feed opening 51 is preferably rectangular to facilitate abutment of the baffle 6 without creating a large gap.

Example 2

In this embodiment, the main structure is completely the same as that of embodiment 1, and the difference lies in the control manner for the rotating shaft 7; in embodiment 1, the electronic telescopic rod 83 is adopted to control the swing of the rotating shaft 7, and here, the stroke of the electronic telescopic rod 83 needs to be accurately controlled, so that the baffle 6 can be ensured to move exactly to the inner wall of the feeding hole 51 every time; this arrangement is better achieved at the beginning of the plant, but the impact of the limestone, against prolonged use, causes deformation and displacement of the plant, so that deviations may occur, resulting in a large gap between the baffle 6 and the inner wall of the feed opening 51.

In order to avoid the above situation, in the present embodiment, the following arrangement is adopted, as shown in fig. 5;

specifically, one end of the rotating shaft 7 extends out of the proportioning bin 1; the drive assembly 8 includes: a driving motor 84, a slide rod 88, a plurality of fixed sleeves 89, a gear 92 and an incomplete sheave.
