Technical Field
[0001] The utility model relates to the field of screening processing, in particular to screening processing equipment for recycled aggregates for high-strength concrete. Background Art
[0002] Recycled concrete aggregate is processed from construction waste. Recycled concrete aggregate can effectively reduce the occupation of land and environmental pollution caused by construction waste. When processing construction waste into construction aggregate, it is necessary to remove the steel bars and wires in the concrete, and then crush the construction waste through a crusher. After that, the construction aggregate is screened to obtain recycled concrete aggregate that meets the requirements. Most aggregate screening equipment drives the screen to vibrate by setting a vibration motor to achieve the effect of aggregate screening. However, coarse particles with a residual particle size larger than the screen holes will accumulate on the surface of the screen, which is difficult to clean. If it is not cleaned in time, the subsequent screening efficiency will be affected. Summary of the invention
[0003] The technical problem to be solved by the utility model is that coarse particles with residual particle sizes larger than the screen holes of the screen will accumulate on the surface of the screen, which is difficult to clean. If it is not cleaned in time, the subsequent screening efficiency will be affected.
[0004] In order to solve the above problems, the technical solution adopted by the utility model is: a screening and processing equipment for recycled aggregate for high-strength concrete, comprising a screening box and a box cover hingedly arranged on one side of the upper end of the screening box, a fixed partition is fixedly arranged on one side of the inner bottom surface of the screening box, the lower part of the interior of the screening box is divided into a coarse material chamber and a fine material chamber by the fixed partition, the lower end of the screening box is respectively provided with discharge ports connected to the coarse material chamber and the fine material chamber, the outer side of the screening box is respectively hingedly provided with side baffles matching the discharge ports, and a screening assembly matching the feed hopper is provided on the upper part of the interior of the screening box.
[0005] The beneficial effects of the utility model are as follows: by setting a coarse material chamber and a fine material chamber, the material screened by the screening box falls into the fine material chamber, and by opening the box cover, the baffle is hingedly arranged to be squeezed and deflected, which makes it convenient for the staff to clean the coarse material remaining on the upper surface of the screening box and drop it into the coarse material chamber, making it convenient for the staff to subsequently carry out centralized processing of the coarse material.
[0006] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the screening assembly includes a screening box and a baffle hingedly arranged on one side of the screening box, and both ends of the baffle are hingedly matched with the upper end of the inner wall of the screening box through a hinge shaft. Directional sliding rods are fixedly provided in the middle of both sides of the screening box, one end of the two directional sliding rods are respectively movably passed through the outside of the screening box, and a spring is sleeved in the middle of the two directional sliding rods, and the opposite ends of the two springs are respectively fixedly connected to the outer wall of the screening box, and the opposite ends of the two springs are in contact with the inner wall of the screening box, and a rotating shaft is provided through the middle of the side wall of the screening box for rotation, the rotating shaft and the baffle are perpendicular to each other and both ends are in a suspended state, and the screening box is rotated away from the inner wall of the baffle and is provided with an eccentric wheel for squeezing the rotating shaft, and a driving device for driving the eccentric wheel to rotate is fixedly provided on the outside of the screening box.
[0007] The beneficial effect of the above improvement is as follows: by setting a directional slide rod, a screening box, a rotating shaft and an eccentric wheel, when the eccentric wheel deflects and squeezes the rotating shaft, it drives the screening box to move to one side and compresses one of the springs; when the eccentric wheel deflects and disengages from the rotating shaft, under the action of the spring reset, the screening box moves in the opposite direction and compresses the other spring, so that the screening box reciprocates and vibrates under the action of the spring reset, thereby achieving the effect of screening materials.
[0008] As a further improvement of the utility model, the technical problem to be solved is: it is difficult to ensure the stability of the horizontal sliding of the screening box.
[0009] In order to solve the above technical problems, the utility model further improves and adopts the technical solution as follows: two driven shafts are symmetrically installed on the inner side of the box cover, and the lower surfaces of the two driven shafts are in contact with the upper surface of the rotating shaft.
[0010] The beneficial effect of the above improvement is: by arranging two driven shafts to press on the upper surface of the rotating shaft, the stability of the horizontal sliding of the screening box is ensured, and the deflection of the screening box is effectively avoided.
[0011] As a further improvement of the utility model, the technical problem to be solved is: it is difficult to ensure the stability of the closing of the box cover and the side baffle plate.

[0013] The beneficial effect of the above improvement is that the stability of the closing of the box cover and the side baffle plate is ensured by the adsorption of the magnet.
[0014] As a further improvement of the utility model, the technical problem to be solved is: it is difficult to automatically and quickly clean up the coarse materials.
[0015] In order to solve the above technical problems, the utility model further improves the technical solution adopted as follows: the fixed partition is located directly below the baffle and there is a gap between the upper end surface of the fixed partition and the lower end surface of the baffle.
[0016] The beneficial effects of the above improvement are as follows: by opening the box cover, the driven shaft is driven to move, the squeeze on the rotating shaft is released, and then when the eccentric wheel squeezes the rotating shaft, the screening box will deflect downward, so that the coarse material automatically and quickly falls into the coarse material chamber, and the continuous deflection of the eccentric wheel causes the screening box to produce a shaking effect, which effectively avoids the accumulation and blockage of the mesh of the screening box, making it convenient for the staff to centrally process the coarse material.

[0023] Embodiment 1:
[0024] like Figure 1-4As shown, a screening and processing device for recycled aggregate for high-strength concrete includes a screening box 1 and a box cover 2 hingedly arranged on one side of the upper end of the screening box 1. A fixed partition 5 is fixedly arranged on one side of the inner bottom surface of the screening box 1. The lower part of the screening box 1 is divided into a coarse material chamber and a fine material chamber by the fixed partition 5. The lower end of the screening box 1 is respectively provided with discharge ports connected to the coarse material chamber and the fine material chamber. The outer side of the screening box 1 is respectively hingedly provided with side baffles 4 matched with the discharge ports. A screening assembly matched with the feed hopper 3 is arranged on the upper part of the screening box 1. By setting the coarse material chamber and the fine material chamber, the material screened by the screening box 6 falls into the fine material chamber. By opening the box cover 2, the baffle 7 is squeezed and deflected due to the hinged setting, which is convenient for the staff to clean the coarse material remaining on the upper surface of the screening box 6 and drop it into the coarse material chamber, so that the staff can centrally process the coarse material later.
[0025] The screening assembly includes a screening box 6 and a baffle 7 hingedly arranged on one side of the screening box 6, both ends of the baffle 7 are hingedly matched with the upper end of the inner wall of the screening box 6 through a hinge shaft, and directional slide bars 12 are fixedly provided in the middle of both sides of the screening box 6, one end of the two directional slide bars 12 respectively moves through the outside of the screening box 1, and a spring 13 is sleeved in the middle of the two directional slide bars 12, and the opposite ends of the two springs 13 are respectively fixedly connected to the outer wall of the screening box 6, and the opposite ends of the two springs 13 are in contact with the inner wall of the screening box 1, and a rotating shaft 8 is provided through the middle of the side wall of the screening box 6 for rotation, and the rotating shaft 8 and the baffle 7 are perpendicular to each other and both ends are in a suspended state, and the screening box 1 is rotated away from the inner wall of the baffle 7. An eccentric wheel 9 for squeezing the rotating shaft 8 is provided, and a driving device 10 for driving the eccentric wheel 9 to rotate is fixedly provided on the outside of the screening box 1. By setting a directional slide rod 12, a screening box 6, a rotating shaft 8 and an eccentric wheel 9, when the eccentric wheel 9 deflects and squeezes the rotating shaft 8, the screening box 6 is driven to move to one side and one of the springs 13 is compressed. When the eccentric wheel 9 deflects and separates from the rotating shaft 8, the screening box 6 moves in the opposite direction and compresses the other spring 13 under the action of the spring 13 resetting, so that the screening box 6 reciprocates and vibrates under the action of the spring 13 resetting, thereby achieving the effect of screening materials.
[0026] Two driven shafts 11 are symmetrically mounted on the inner side of the box cover 2, and the lower surfaces of the two driven shafts 11 are in contact with the upper surface of the rotating shaft 8.

[0027] A handle is fixedly provided on one side of the upper end of the box cover 2, a first magnet is embedded at the edge of the lower end surface of the box cover 2, and a second magnet is embedded at the lower inner end of the side baffle plate 4. The screening box 1 is made of iron material. The magnet has adsorption properties, thereby ensuring the stability of the box cover 2 and the side baffle plate 4 when closed.
[0028] The fixed partition 5 is located directly below the baffle 7 and there is a gap between the upper end surface of the fixed partition 5 and the lower end surface of the baffle 7. By opening the box cover 2, the driven shaft 11 is driven to move, and the extrusion of the rotating shaft 8 is released. Then, when the eccentric wheel 9 squeezes the rotating shaft 8, the screening box 6 will deflect downward, so that the coarse material automatically and quickly falls into the coarse material cavity, and the continuous deflection of the eccentric wheel 9 makes the screening box 6 produce a shaking effect, which effectively avoids the accumulation and blockage of the mesh of the screening box 6, and is convenient for the staff to centrally process the coarse material.
