The present invention relates to a selective mixing transfer device of crushed aggregate, and more specifically, during the screening operation of the aggregate, the operator checks the state of the aggregate with the naked eye and allows the aggregate to be selectively separated by opening and closing the corresponding outlet through the sorting plate. By selectively opening and closing the sorting plate, it is possible to selectively control the sorting output of aggregate, so it can be usefully applied in the production of mixed aggregate, and it can be applied to the crushed aggregate sorting and conveying device that can completely remove the remaining aggregate on the conveyor belt. It is about.

In general, the selective mixing and transporting device of crushed aggregate is crushed construction waste mixed with foreign matter contained in waste soil and soil and aggregate by crusher, and the foreign matter, soil and aggregate contained in the pulverized crushed material are separated And re-separating the fine aggregates including fine aggregates contained in the waste soil which is disposed of in the process of being sorted by particles, and washing and sorting and crushing them to remove clay and paste to obtain high quality fine aggregates. Say the device.

On the other hand, the brush unit 50 may be preferably rotated in the direction opposite to the traveling direction of the conveyor belt 13 so that the fine aggregate and the like on the surface of the conveyor belt 13 more reliably.

The sorting hopper 20 is disposed in the lower portion adjacent to the upper drive roller 11 of the conveying conveyor 10, the inlet 21 is formed at the upper end and both sides along the inclined direction of the conveying conveyor 10 at the lower end. The so-called pants shape (reverse Weiza shape) is provided with divided first and second discharge ports 22 and 23.

That is, referring to Figure 1, the first discharge port 22 of the sorting hopper 20 is located on the left side immediately below the aggregate that is injected through the inlet 21 immediately, the second outlet 23 is It is located on the right side of this first outlet 22.

The aggregate selection unit 30 is disposed on the first and second outlets 22 and 23 of the sorting hopper 20 to drop the aggregate falling from the inlet 21 to the first and second outlets 22 and 23. In particular, the guide screening unit, the aggregate selection unit 30 is selected to only one of the outlets while the outlet of any one of the first, second outlets (22, 23) to be kept open continuously. Aggregate can be selected while opening and closing.

In more detail, the aggregate selection unit 30 is disposed in parallel to the inner surface of the second outlet 23 in an inclined state to slide both up and down to selectively open and close the first outlet 22 on both sides. Both rollers formed with a sorting plate 31 provided with a roller 31b rotated by the rotating shaft 31a, and a through hole 32a through which the rotating shaft 31a of the sorting plate 31 passes and exposed to the outside. The guide rail 32b for guiding the 31b is configured to include a side wall support plate 32 provided outside the wall surface and sliding means for vertically sliding the sorting plate 31.

Here, the sorting plate 31 is in the shape of a rectangular square plate, and the rotary shaft 31a is disposed at the front and rear portions thereof in the longitudinal direction, and the roller 31b is rotatably mounted at both ends of the rotary shaft 31a. have.

The side wall support plate 32 is disposed on both sides of the sorting plate 31 to axially support the rotation shaft 31a of the sorting plate 31 and the gear rotation shaft 42 of the pinion gear 42. There is a pair of walls for slidably guiding 31).

The sliding means includes a rack plate 41 having a rectangular plate shape which is formed in the bottom surface of the sorting plate 31 along the longitudinal direction and has gear teeth formed thereon, and the rack below the rack gear 41. A pinion gear 42 having a gear rotating shaft 42a which is engaged with the gear 41 and rotates and penetrates the side wall support plate 32 and is exposed to the outside, and one end of the gear rotating shaft 42a of the pinion gear 42. It is configured to include a sprocket 44 is coupled to the drive motor chain 43a and transmits power to the pinion gear.

Here, the outer circumferential surface of the gear rotation shaft 42a in close contact with the side wall support plate 32, that is, the outer surface of the side wall support plate 32 through which the gear rotation shaft 42a penetrates, is for supporting the shaft rotation of the gear rotation shaft 42a. The bearing member 45 is provided.

The sorting mixing transfer device of the crushed aggregate of the present invention according to this configuration first operates the conveying conveyor 10 to transfer the aggregate to the inlet 21 side of the sorting hopper 20. At this time, the operator grasps the aggregate state on the conveyer belt 13 with the naked eye and selects which discharge port of the first and second discharge ports 22 and 23 to discharge, and then moves the sorting plate 31 in a desired direction. By automatically sliding to the first outlet 22 to selectively open and close the aggregate can be selected.

As an example, it will be described assuming that the non-conforming aggregate is discharged through the first discharge port 22 and the suitable aggregate is discharged through the second discharge port 23.

First, in the case where the aggregate conveyed to the conveying conveyor 10 is a suitable aggregate, the operator checks this with the naked eye and then operates the driving motor 43 to close the first discharge port 22 by sliding the sorting plate 31 up and down. It is to be made.

Then, the suitable aggregate falling from the inlet 21 is blocked by the sorting plate 31 which closes the 1st outlet 22, and as a result, it slides toward the 2nd outlet 23 by riding on the upper surface of this sorting plate 31. As shown in FIG. It goes down and is discharged to the outside.

Here, when the drive motor 43 transmits the rotational force to the sprocket 44 through the drive motor chain 43a, the pinion gear 42 is rotated at the same time while the rack gear 41 of the selection plate 31 is rotated. As a result, the sorting plate 31 is slid upward and operated to close the first outlet 22. At this time, the drive motor 43 preferably has a brake device to prevent sliding down by the weight of the falling aggregate as well as the weight of the sorting plate (31).

On the contrary, in the case where the aggregate to be conveyed is an inadequate aggregate, the operator also checks this with the naked eye, and then reversely operates the driving motor 43 in reverse to the above, so that the sorting plate 31 slides down and slides the first outlet 22. Open.

Then, the aggregate injected through the inlet 21 is discharged to the outside while falling directly to the first outlet 22 without being discharged to the second outlet 23 which is mostly open.

This phenomenon is slightly blown forward when the aggregates fall due to the propulsion force according to the conveying rotational force of the conveyor belt 13 so that the aggregate is blown against the inner wall surface of the upper sorting hopper 20 of the first outlet 22 It is to fall to the first outlet 22 immediately downward.

Here, when the drive motor 43 transmits the rotational force to the sprocket 44 through the drive motor chain 43a, the pinion gear 42 is rotated at the same time, and the rack gear 41 of the sorting plate 31 is reversed. As a result, the sorting plate 31 is slid down and operated to open the first outlet 22.

On the other hand, the sorting plate 31 of the aggregate selection unit 30 may completely open or close the first outlet 22, or selectively open and close only a portion of the first outlet 22 by opening and closing only a predetermined distance. Could be

6 to 8 are views showing to explain another embodiment of the selective mixing and transporting apparatus of the crush aggregate of the present invention. Here, the stopper for suppressing the sliding of the sorting plate 31 to the aggregate selection unit 30 to prevent the sorting plate 31 from sliding downward due to the weight of the falling aggregate as well as the weight of the sorting plate 31. The part 60 is provided. The stopper part 60 is supported on the bracket 61 having one end fixed to the side wall support plate 32 and is mounted on the stopper pin 62 which is projected by power supply, and the position corresponding to the appearance of the stopper pin 62. The stopper pin 62 is inserted into the guide rail 32b along the longitudinal direction, and is composed of a plurality of stopper grooves 63 to be temporarily fixed.

In addition, the stopper pin 62 is separated from the stopper groove 63 when the power supply for sliding of the separating plate 31 is removed, and the electromagnet is inserted into and supported by the stopper groove 63 directly below when the power is cut off. Combined with (64).

That is, as in the general operation principle of the solenoid made of a coupling relationship between the stopper pin 62, the electromagnet 64 and the spring 65, when the power is applied to the electromagnet 64, the stopper pin 62 is electromagnet by magnetic force When pulled to the (64) side and the power is cut off, the sorting plate 31 is fixed while being elastically supported in a state of being lowered downward by the elasticity of the spring 65 due to the loss of magnetic force.

In the mixed mixing transfer device of the crushed aggregate according to another embodiment as described above, the aggregate selection operation is performed by the same process as described in an embodiment, the process of sliding the sorting plate 31 in the desired direction only It's different.

In the process of sliding the sorting plate 31 in a desired direction, when power is applied to the driving motor 43, the stopper pin 62 of the stopper unit 60 is separated from the stopper groove 63 to separate the sorting plate 31. ) Is in a slidable state. In other words, the stopper pin 62 of the electromagnet 64 protrudes and is inserted into the stopper groove 63 in the state where power is not applied to the driving motor 43.

Subsequently, the sorting plate 31 is slid up and down so that the sorting plate 31 is vertically slid by driving the driving motor 43 in the forward and reverse directions as described in the embodiment of the present invention.

That is, when the drive motor 43 is driven, the rotational force is transmitted to the sprocket 44 through the drive motor chain 43a, and the pinion gear 42 is rotated as the gear shaft 40 rotates together with the sprocket 44. While rotating, the rack gear 41 of the sorting plate 31 is advanced, and as a result, the sorting plate 31 is slid up or down to operate to close the first and second outlets 22 and 23.

In this way, when the sliding of the selection plate 31 is completed and the operating power of the driving motor 43 is cut off, the power is also simultaneously cut off at the same time as the electromagnet 64 of the stopper part 60, whereby the stopper pin 62 springs. It is pushed downward by the repelling force of 65 and is inserted into the stopper groove 63 directly below to be elastically supported to securely fix the sorting plate 31.

Therefore, it is possible to apply and use a general starting drive motor instead of an expensive drive motor 43 having a brake device.

As described above, the screening and mixing transfer device of the crushed aggregates according to the present invention can be separated and aggregated while opening and closing the corresponding outlet through the sorting plate while the operator visually checks the state of the aggregates during the aggregate selection operation Freely control the degree of opening and closing of the sorting plate during the aggregate sorting operation, it is possible to selectively control the sorting output of aggregates according to the aggregates, and to improve the work efficiency by continuously adjusting the mixing particle size ratio during the production of mixed aggregates without stopping the aggregate sorting operation. Effect such as

In addition, the present invention can completely remove the remaining aggregate on the conveyor belt with a brush or the like, so that the surface of the conveyor belt and the surrounding environment of the conveying conveyor is clean, thereby eliminating the need for collecting the remaining aggregate.

And the present invention is securely and surely maintained as it is opened and closed by operating the sorting plate of the aggregate selection unit, and can be used as an inexpensive general starting drive motor instead of an expensive driving motor having a brake device.
