[0002] Concrete aggregate screening equipment is mainly used to classify and screen aggregates (such as sand, stone, etc.) required in concrete production to ensure that the particle size and quality of the aggregates meet the requirements of the concrete mix design.

[0003] However, in actual use, the following deficiencies still exist. For example, existing concrete aggregate screening equipment cannot separate aggregates of different sizes, and the quality of the screened material is uneven. If the quality of the screened aggregate is uneven, it may lead to unstable properties such as concrete strength, durability and workability. In addition, the low degree of automation and single function of the equipment also limit its scope of application, thereby affecting production efficiency and product quality.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments 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 making creative efforts are within the scope of protection of the present invention.

[0030] Example 1

[0031] like Figure 1-Figure 3 As shown, this embodiment provides a technical solution: a concrete aggregate screening device, comprising a box body 1, a feed port 2 provided on the box body 1, a box door 3 rotatably connected to the box body 1, a support frame 4 provided inside the box body 1, a first screening box 5 slidably connected to the support frame 4, and a vibration assembly 6 provided on one side of the box body 1 near the bottom of the support frame 4;

[0032] like Figure 1-Figure 3 As shown, the vibration assembly 6 includes a fixed shell 61 and a fixed rod 67, the fixed shell 61 is rotatably connected to the first rotating shaft 63, the first rotating shaft 63 is fixedly connected to the eccentric block 64, the eccentric block 64 is rotatably connected to the first rotating rod 65, the first rotating rod 65 is rotatably connected to the moving block 66, the fixed rod 67 is fixedly connected to the first telescopic spring 68, the other end of the first telescopic spring 68 is fixedly connected to the fixed block 69, the fixed shell 61 is fixedly connected to the telescopic rod 611, the other end of the telescopic rod 611 is fixedly connected to the support frame 4, and the telescopic rod 611 is provided with a second telescopic spring 612. When the operator starts the transmission motor 62, the output end of the motor will drive the first rotating shaft 63 to rotate. As the first rotating shaft 63 rotates, the eccentric block 64 also starts to rotate, thereby causing the first rotating rod 65 and the moving block 66 to rotate. It moves up and down, and this up and down movement causes the moving block 66 to hit the fixed rod 67. Since the top of the fixed rod 67 is fixedly connected to the box body 1, the fixed rod 67 can continuously vibrate the support frame 4. In order to enhance the vibration effect and ensure that it can be effectively transmitted to the support frame 4, a telescopic rod 611 and a second telescopic spring 612 are provided in the equipment. These two components cooperate with each other to further transmit the vibration effect generated by the fixed rod 67 to the support frame 4. In this way, the support frame 4 can always be in a vibrating state. A first screening box 5 with different sieve holes is provided on the support frame 4. The design of these screening boxes enables the equipment to separate aggregates of different sizes and ensure that the quality of the screened materials is uniform, thereby solving the technical problem of separating aggregates of different sizes and ensuring uniform quality of the screened materials.

[0033] Example 2

[0034] In the above solution, there is still a problem that the second screening box 8 cannot be supported when the second screening box 8 is taken out from the box body 1. Figure 1-Figure 3 As shown: the fixed shell 61 is fixedly connected to the box body 1, and the transmission motor 62 is installed on the box body 1. The first rotating shaft 63 is fixedly connected to the output end of the transmission motor 62. Since the fixed shell 61 is fixedly connected to the box body 1, the box body 1 can support and fix the fixed shell 61. Since the transmission motor 62 is installed on the box body 1, and the first rotating shaft 63 is fixedly connected to the output end of the transmission motor 62, when the transmission motor 62 is started, the output end of the transmission motor 62 can drive the first rotating shaft 63 to rotate. The fixed block 69 is slidably connected to the fixed rod 67, and the fixed block 69 is fixedly connected to the moving block 66. The limiting column 610 is fixedly connected to the support frame 4, and the moving block 66 is slidably connected in the limiting column 610. Since the fixed block 69 slides It is connected to the fixed rod 67, and the fixed block 69 is fixedly connected to the moving block 66, so that when the moving block 66 moves, the moving block 66 can drive the fixed rod 67 to vibrate back and forth. Since the support frame 4 is fixedly connected to the limiting column 610, and the moving block 66 is slidably connected in the limiting column 610, the limiting column 610 can limit the movement of the moving block 66. One end of the second telescopic spring 612 is fixedly connected to the support frame 4, and the other end of the second telescopic spring 612 is fixedly connected to the fixed shell 61. Since one end of the second telescopic spring 612 is fixedly connected to the support frame 4, and the other end of the second telescopic spring 612 is fixedly connected to the fixed shell 61, the second telescopic spring 612 can provide an elastic force to the support frame 4;

[0035] like Figure 1 as well as Figure 4 When the locking cam 75 is in the unlocked position, the locking cam 73 is locked and the locking cam 73 is in the unlocked position, so that the block 75 can be locked.

[0036] like Figure 1 as well as Figure 5As shown, the inner bottom of the box body 1 is slidably connected to the second screening box 8, and a support assembly 9 is provided on one side of the inner bottom of the box body 1 near the second screening box 8. The support assembly 9 includes a support plate 91, which is fixedly connected to the second screening box 8. When the second screening box 8 is pulled out of the box body 1, the elastic force of the spring provided on the rotating column 93 drives the rotating block 92, the second rotating rod 94 and the second rotating shaft 95 to rotate. The supporting plate 91 is rotatably connected to the rotating block 92, the rotating block 92 is rotatably connected to the rotating column 93, the rotating column 93 is rotatably connected to the second rotating rod 94, and the other end of the second rotating rod 94 is rotatably connected to the second rotating shaft 95. The second rotating shaft 95 is rotatably connected to the supporting leg 96, so that the second rotating shaft 95 drives the supporting leg 96 to rotate, and the supporting leg 96 will rotate until it is in vertical contact with the ground, so that the supporting leg 96 can support the second screening box 8.
