Technical Field
The utility model relates to an asphalt concrete production facility technical field, more specifically relate to an asphalt concrete aggregate drum-type screening plant.
Background
Asphalt concrete, known as asphalt concrete, is prepared by mixing asphalt with aggregate such as broken stone and mineral powder in a certain proportion, and is mainly used for paving road surfaces. The asphalt concretes with different models and standards have different production standards, and the main difference is that the granularity of the adopted aggregates is different. And then in the production process of asphalt concrete, the corresponding aggregate needs to be screened aiming at the asphalt concrete with different models and standards, and the screening process needs to use the corresponding screening device.
What current conventional screening plant adopted is vibrating screen, and vibrating screen level sets up, then places the aggregate on vibrating screen, and the aggregate that makes to satisfy the granularity requirement through the vibration passes vibrating screen and falls and unify the collection, and the aggregate that the granularity is too big stays on vibrating screen to realize the screening of aggregate. However, aggregates with too large granularity left on the vibrating screen can be screened next time after being unloaded, and the unloading is generally carried out manually, which is very inconvenient. At present, a vibrating screen is also obliquely arranged, so that aggregates can automatically slide under the action of gravity without manual discharging. However, the time for the aggregate to slide down is fixed in the structure, and the screening can only be performed in the process of the aggregate sliding down, so that the screening time cannot be controlled randomly, and the aggregate screening is possibly insufficient.

Detailed Description
For a better understanding of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and the following embodiments.
Example 1
The utility model provides an asphalt concrete aggregate drum-type screening plant, including setting up between two stands 5 and both ends confined cylinder 2, be provided with the motor 1 of 2 upsets of driving roll on the stand 5 of one side, 2 barrels of cylinder adopt porous otter board to make, material mouth 4 has been seted up along its axis on 2 barrels of cylinder, 2 barrels of cylinder of material mouth 4 one side are to 2 inside bending of cylinder and extend and form curved hem 3, hem 3 projection on 2 barrels of cylinder can shelter from material mouth 4 completely, 2 below cylinders are provided with the case 9 that gathers materials, the case 9 that gathers materials divides into two collection chambeies 10 about using 2 axis projections of cylinder department as the boundary, the slope of case 9 top that gathers materials is provided with and collects the play flitch 8 that chamber 10 corresponds, it is connected with stand 5 through the pivot to go out flitch 8 both ends center, be provided with on the stand 5 and can drive the drive mechanism 11 that goes out.
The working principle is as follows: as shown in the attached drawing 1, when feeding, the motor 1 drives the roller 2 to rotate until the material opening 4 faces upwards, aggregate is fed into the roller 2 through the material opening 4 from bottom to bottom, then the motor 1 drives the roller 2 to rotate clockwise, and the aggregate is rolled and sieved in the roller 2. Due to the existence of the folded edge 3 and the projection of the folded edge 3 on the barrel body of the roller 2, the material opening 4 can be completely shielded, and then the aggregate in the roller 2 can not fall out of the material opening 4. In the process of turning over the aggregates, the small-particle aggregates fall onto the discharging plate 8 through the porous cylinder body of the roller 2 and slide down to a collecting cavity 10 of the aggregate box 9 along the discharging plate 8. After a period of screening, only large granule aggregate remains in the cylinder 2, and control motor 1 reversal then makes cylinder 2 along anticlockwise rotation, and motor 1 makes ejection of compact board 8 upset to opposite incline direction through drive mechanism 11 this moment, and ejection of compact board 8 corresponds with another collection chamber 10 in the case 9 that gathers materials this moment. The drum 2 rotates anticlockwise to enable large-particle aggregates inside to fall onto the discharging plate 8 through the material opening 4, and then the large-particle aggregates fall into the corresponding collecting cavity 10 along the discharging plate 8. Large granule aggregate discharge gate 4, control motor 1 here drives the cylinder 2 and rotates to material mouth 4 up, carries out the feeding screening next time. Because the height of the material opening 4 facing upwards is higher, the material can be fed by matching with a feeding conveying device, such as a belt conveyor or a screw conveyor.
It should be noted that the rotation speed of the drum 2 should not be too high, so the output end of the motor 1 should be provided with a speed reducer.
The utility model discloses change the screening of aggregate into the drum-type, even the rotatory process of cylinder is sieved in-process, the time of this process can freely be controlled, and then can carry out more abundant screening with the aggregate. Simultaneously, this device carries out corresponding improvement with the cross sectional shape of cylinder, to the large granule raw materials that the screening was come out, only needs the counter rotation cylinder just can discharge from the material mouth, need not the manual work and unloads. Therefore, the device overcomes the defects of inconvenient use and insufficient screening in the prior art.
Example 2
The embodiment is improved on the basis of embodiment 1:
The outer sides of the two ends of the rack 11.2 on the upright post 5 are provided with limit grooves 13 with notches facing the tail ends of the rack 11.2, and springs 14 are arranged in the limit grooves 13. The limiting groove 13 limits the movement of the rack 11.2 to prevent the rack from moving excessively, and the existence of the spring 14 ensures that the rack 11.2 can be in contact with the driving gear 11.1 and the driven gear 11.3 to prevent the meshing part from being completely separated and not being meshed again.
The material collecting box 9 is provided with a door-shaped limiting frame 7 which is used for limiting the overturn of the discharging plate 8 and is arranged above the two collecting cavities 10, and the limiting frame is used for preventing the discharging plate 8 from overturning excessively.
The edges of the two ends of the discharging plate 8 close to the upright columns 5 on the two sides are respectively provided with a flange 6 which is turned over upwards by 90 degrees, and the flanges 6 can prevent the aggregates from spilling from the edges of the two ends of the discharging plate 8 when being discharged.
The above description is only for the preferred embodiment of the present invention, and the present invention is not limited thereto, the protection scope of the present invention is defined by the claims, and all structural changes equivalent to the contents of the description and drawings of the present invention should be included in the protection scope of the present invention.
