[0002] Asphalt concrete recycling refers to the process of crushing, cleaning, and grading discarded concrete blocks or asphalt blocks, mixing them with grading in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel (mainly coarse aggregates), and then adding cement, water, etc. to make new concrete.

[0003] Reference patent publication number "CN219168534U" discloses an asphalt concrete recycled aggregate screening device, including a supporting and unloading mechanism, a processing bin is connected to the top of the supporting and unloading mechanism, a crushing roller is rotatably arranged between the two sides of the inner wall of the processing bin, and one end of the crushing roller extends outside the processing bin and is connected to a driving motor.

[0004] This patent crushes the recycled aggregate of asphalt concrete by setting up a crushing mechanism, and then screens it after crushing. When the recycled aggregate of asphalt concrete is fed, it enters from the top of the crushing mechanism, and the entering materials are concentrated in the middle part of the crushing mechanism.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The asphalt concrete recycled aggregate screening equipment provides two technical solutions:

[0024] like Figure 1 and 2 The first embodiment is shown: it includes a main box 1 and a screening mechanism and a crushing mechanism 2 installed inside the main box 1, and a feeding mechanism is arranged above the crushing mechanism 2, and the feeding mechanism includes:

[0025] A uniform feeding component 3 includes two front and rear support plates 31, both support plates 31 are fixedly connected to the top of the main box body 1, a slide rail 32 is fixedly connected between the two support plates 31, a hopper 33 is slidably connected in the slide rail 32, a guide groove block 34 is fixedly connected to the left side of the hopper 33, a gantry 35 is fixedly connected to the top of the main box body 1, and a drive motor 36 is fixedly connected to the top of the gantry 35, a disc 37 is fixedly connected to the output end of the drive motor 36, and a cylindrical rod 38 matching the guide groove block 34 is fixedly connected to the right side of the disc 37, and a guide groove is opened inside the guide groove block 34, and the cylindrical rod 38 is in the guide groove in the guide groove block 34.

[0026] When feeding the recycled aggregate of asphalt concrete, the uniform feeding component 3 is used to make the material fall evenly into the crushing mechanism 2, so that the material can also fall evenly into the screening mechanism. After the material enters, it can be screened quickly, thereby improving the working efficiency and screening effect of the device.

[0027] like Figure 1 and 3 The second embodiment is shown, which is mainly different from the first embodiment in that: the feed amount control component 4 is arranged below the uniform feeding component 3, and is used to control the amount of material falling from the uniform feeding component 3 into the crushing mechanism 2. The feed amount control component 4 includes two groups of left and right blocks 41, and the two blocks 41 are composed of two front and rear blocks 41, and the two groups of blocks 41 are respectively fixed to the left and right sides of the front and rear support plates 31, and the two groups of blocks 41 are fixedly connected with an intermediate rod 42, and the surfaces of the two intermediate rods 42 are rotatably connected with baffles 43, and the intermediate rods 42 The surface outside the baffle 43 is sleeved with a torsion spring 48, one end of the torsion spring 48 is fixedly connected to the surface of the intermediate rod 42, and the other end of the torsion spring 48 is fixedly connected to the baffle 43, the back of the rear support plate 31 is fixedly connected to an adjustment motor 44, and the output end of the adjustment motor 44 is fixedly connected to a lead screw 45, the surface of the lead screw 45 is threadedly connected to a moving sleeve 46, and the moving sleeve 46 penetrates the support plate 31 and extends to the front of the support plate 31, and the end of the moving sleeve 46 located in front of the support plate 31 is fixedly connected to a push plate 47, and the push plate 47 is located between the two baffles 43.

[0028] When the material falls, the feed amount is controlled by the opening size between the two baffles 43 in the feed amount control component 4, so that the feed amount can be matched with the working efficiency of the crushing mechanism 2 to avoid the material from piling up above the crushing roller in the crushing mechanism.

[0029] When in use, the material enters the hopper 33, and the material falls naturally from the bottom of the hopper 33. At the same time, the driving motor 36 is started to rotate the disc 37, and the disc 37 rotates and drives the cylindrical rod 38 to rotate. The cylindrical rod 38 rotates and cooperates with the guide groove block 34 to make the hopper 33 reciprocate back and forth, so that the material enters the crushing mechanism 2 through the opening of the two baffles 43. If the crushing speed of the crushing mechanism 2 cannot keep up with the falling speed of the material, the adjustment motor 44 is started to rotate the screw rod 45, and the screw rod 45 rotates and drives the push plate 47 to move upward through the movable sleeve 46, and with the cooperation of 48, the two baffles 43 are rotated, thereby reducing the size of the opening between the two baffles 43. Otherwise, the push plate 47 moves downward to increase the opening.
