[0025] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Combined with reference Figures 1 - 5 The utility model provides a solid waste recycled concrete aggregate crushing equipment, including a shell 1, the top of the shell 1 is fixedly connected to a feed hopper 2, a pair of concrete crushing rollers 3 are rotatably connected inside the shell 1 and below the feed hopper 2, and a driving device 1 for driving the pair of concrete crushing rollers 3 to rotate is provided on the shell 1. The driving device 2 in the present application can adopt a combination of a crushing motor and a pair of gears. The crushing motor is fixed on the shell 1 and fixedly connected to the shaft end of one of the concrete crushing rollers 3. The pair of gears are meshed with each other and fixedly connected to the other shaft end positions of the pair of concrete crushing rollers 3, respectively, so that the pair of concrete crushing rollers 3 can face each other and rotate to crush the concrete waste.

[0027] At least two pairs of material transport components 5 are arranged in the shell 1, and the material transport component 5 includes a hollow rotating shaft 51 rotatably connected to the inner wall of the shell 1 and a material transport barrel 52 fixedly connected to the hollow rotating shaft 51. The material transport barrel 52 is located below the concrete crushing roller 3, and the material transport barrel 52 is used to carry the crushed materials crushed by the concrete crushing roller 3. In this application, the positions of the two material transport barrels 52 should be stepped, and the same is true for multiple material transport barrels 52. A driving device 2 for driving a pair of hollow rotating shafts 51 to rotate is arranged on the shell 1. In this application, the driving device 2 can adopt a combination of a crushing motor and a belt transmission mechanism. The crushing motor is fixed on the shell 1 and fixedly connected to one of the hollow rotating shafts 51. The belt transmission mechanism can be transmission-connected to a pair of hollow rotating shafts 51, so that a pair of material transport barrels 52 can rotate synchronously.

[0028] Above the material conveying cylinder 52, there is a blanking hopper 4. The blanking hopper 4 is fixedly connected inside the housing 1. A number of aggregate boxes 6 are detachably connected to the material conveying cylinder 52. An adsorption assembly 7 is arranged inside the aggregate box 6. The adsorption assembly 7 includes a pair of adsorption plates 71 fixedly connected to both sides of the inner wall of the aggregate box 6 and a plurality of adsorption rods 72 fixedly connected to the inner bottom of the aggregate box 6. In this application, both the adsorption plates 71 and the adsorption rods 72 use electromagnets in the form of plates and rods. When the material conveying cylinder 52 drives the aggregate box 6 to rotate, after the crushed concrete crushed by the concrete crushing roller 3 is concentrated and falls into each aggregate box 6 through the blanking hopper 4, at this time, the energized adsorption plates 71 and adsorption rods 72 can adsorb the iron materials in the crushed materials. When the aggregate box 6 rotates to a certain angle on the material conveying cylinder 52, the concrete blocks in the crushed materials can freely fall, and the iron materials continue to be adsorbed on the adsorption plates 71 and adsorption rods 72. Subsequently, by de-energizing the adsorption plates 71 and adsorption rods 72, the iron materials can be transferred to another collection area.

[0029] The aggregate box 6 is in a fan-shaped structure, and the inside of the aggregate box 6 is hollow. A receiving groove for inserting the aggregate box 6 is provided on the material conveying cylinder 52, which facilitates the taking and placing of the aggregate box 6.

[0030] A fixed disk 9 is fixedly connected to the hollow rotating shaft 51. A positioning column 10 is fixedly connected to one end of the aggregate box 6. The positioning column 10 is movably inserted into the fixed disk 9. An electronic switch 11 is fixedly connected to the fixed disk 9. The electronic switch 11 is a switch structure in the prior art, which can mainly achieve the switching effect of multi-control of multiple electrical components and will not be elaborated here.

[0031] A support 12 is fixedly connected to one side of the housing 1. A slip ring 13 is arranged on the support 12. The slip ring 13 can effectively provide signal or power transmission for the rotating adsorption plates 71 and adsorption rods 72 when the material conveying cylinder 52 rotates. The slip ring 13 is also a structure in the prior art and can be directly purchased on the market, so it will not be elaborated here. The slip ring 13 is arranged at one end of the hollow rotating shaft 51. The slip ring 13 is electrically connected to the adsorption plates 71 and the adsorption rods 72 through the electronic switch 11 respectively. The electronic switch 11 can be connected to the adsorption plates 71 and the adsorption rods 72 through corresponding wires.

[0032] Specifically, when an upper material transporting cylinder 52 collects crushed materials pulverized by the concrete pulverizing roller 3 through the aggregate box 6, the adsorption component 7 in the aggregate box 6 can be electrified to adsorb the iron materials in the crushed materials at this time. The continuous rotation of the material transporting cylinder 52 can cause the aggregate box 6 to tilt downward and pour out the concrete materials in the crushed materials. The poured concrete materials can be received by the aggregate box 6 on the lower material transporting cylinder 52. In this way, the screening quality of the iron materials in the crushed materials can be further improved. Until the aggregate box 6 pours out the concrete materials therein, the adsorbed iron materials in the aggregate box 6 can cancel the power-on control of the adsorption component 7 in the coordinate area of the third quadrant. In this way, the iron materials and the concrete materials can be sorted and collected, and the concrete pulverizing roller 3 can achieve the effect of continuous operation, and sorting can be directly carried out without stopping the machine.

[0033] It should be noted that the quantity of the material transporting component 5 and its upper structure in this application can be increased according to the requirements of the crushed materials, and at least ensure that the quantity is greater than or equal to two. In addition, in order to improve the on-off control of the adsorption component 7 at the specified position, object detection modules such as a photoelectric module and an ultrasonic module need to be configured in the housing 1 of this application to monitor the use position of the adsorption component 7.

[0034] A movable disk 14 is slidably connected to the hollow rotating shaft 51. The other end of the aggregate box 6 is fixedly connected with a positioning column two 15. The positioning column two 15 is movably inserted on the movable disk 14. A fastening nut 16 is threadedly connected to the hollow rotating shaft 51, and the fastening nut 16 abuts against the movable disk 14.

[0035] Specifically, when it is necessary to maintain the adsorption component 7 on the aggregate box 6, the fastening nut 16 can be rotated at this time to release the abutting force of the fastening nut 16 on the movable disk 14. By controlling the movable disk 14 to move away from one end of the material transporting cylinder 52, the lateral limitation of the insertion of the positioning column one 10 and the positioning column two 15 can be released, and then the aggregate box 6 can be taken out.

[0036] An inspection door 18 is connected to the housing 1 through a hinge, and the position of the inspection door 18 is convenient for maintaining the internal structure of the housing 1.

[0037] A pair of material discharging ports 17 are opened at the bottom of the housing 1. The material discharging ports 17 are located on both sides below the triangular seat 8. The pair of material discharging ports 17 can be respectively used to provide independent discharging channels for the concrete crushed materials and the iron materials.
