[0002] When large-scale and stable production of concrete, mortar or other building materials is required, aggregate premixing devices are used to ensure uniform mixing and consistency of quality of aggregates.

[0003] Aggregate premixing units can mix aggregates of different types, sizes and properties to achieve specific physical and mechanical properties.

[0004] When existing aggregate premixing devices mix different types of aggregates, in order to prevent debris, large impurities, etc. from mixing into the machine body, affecting the mixing quality and damaging the equipment, it is usually necessary to set a screening plate in the feed hopper to screen the impurities in the aggregate. Aggregates are usually concentrated in the central area of ​​the screening plate when entering the feed hopper. Therefore, during the screening process, blockage is very likely to occur. The blocked screening plate will affect the entry of aggregates, thereby causing uneven mixing. To address this problem, we have proposed an aggregate premixing device. Utility Model Content

[0025] The dial plate 71 fits with the surface of the sieve plate 5, and a moving block 72 is fixedly installed on the surface of the dial plate 71. The surface of the moving block 72 fits with the inner wall of the limit frame 74. The limit frame 74 is fixedly installed on the surface of the fixed plate 6. The inner wall of the limit frame 74 is provided with a slide rail 75. The inner wall of the limit frame 74 is fixedly connected to one end of a spring 73, and the other end of the spring 73 is fixedly installed on the surface of the moving block 72. The surface of the cross bar 77 is hinged to one end of the push rod 76, and the other end of the push rod 76 is hinged to the surface of the moving block 72. The surface of the fixed plate 6 is provided with a rotating member 78 for rotation. When 77 moves, the push rod 76 hinged on the surface of the cross bar 77 can be folded, pushing the moving block 72 to slide in the limit frame 74 under the support of the spring 1 73. When the moving block 72 moves, the paddle plate 71 fixed on the surface of the moving block 72 is continuously moved on the surface of the sieve plate 5. Since the slider 784 is in horizontal reciprocating motion, the paddle plate 71 can be continuously moved on the surface of the sieve plate 5. This method can push the aggregates gathered in the central area to various places of the sieve plate 5, so that the aggregates that meet the particle size requirements can pass through the sieve holes more quickly and smoothly, thereby improving the screening speed and efficiency.

[0026] The rotating member 78 includes: a support block 781, which is fixedly mounted on the surface of the fixed plate 6, and the surface of the support block 781 is in contact with the surface of the crossbar 77. The arrangement of two groups of support blocks 781 can ensure the stable movement of the crossbar 77. A vertical rod 782 is fixedly mounted on the surface of the crossbar 77, and the vertical rod 782 penetrates the fixed plate 6 and is slidably connected with the fixed plate 6. The inner wall of the fixed plate 6 is fixedly connected with one end of the second spring 783, and the other end of the second spring 783 is fixedly mounted on the surface of the vertical rod 782. The vertical rod 782 can drive the crossbar 77 to move laterally under the support of the second spring 783. A slider 784 is fixedly mounted on the surface of the vertical rod 782, and the slider 784 is in contact with the surface of the fixed plate 6. When the slider 784 moves on the surface of the fixed plate 6, the vertical rod 782 can slide in the fixed plate 6. The surface of the slider 784 is hinged to one end of the movable rod 785, and the other end of the movable rod 785 is hinged to the surface of the circular plate 786. The circular plate 786 is rotatably connected to the surface of the fixed plate 6. The surface of the fixed plate 6 is fixedly mounted with a motor 787, and the output shaft of the motor 787 is fixedly connected to the surface of the circular plate 786.

The driven component 8 includes: a connecting rod 81, the surface of the connecting rod 81 is fixedly mounted on the surface of the slider 784, and when the slider 784 moves, the connecting rod 81 can synchronously slide laterally. A flat rod 82 is fixedly mounted on the surface of the connecting rod 81, and a knocking rod 83 is fixedly mounted on the surface of the flat rod 82. When the connecting rod 81 moves, the flat rod 82 can drive the knocking rod 83 to synchronously move laterally.

[0027] In the utility model, when in use, the aggregate to be premixed is poured into the feed frame 3, and the sieve plate 5 in the feed frame 3 screens the aggregate. During the screening process, the motor 787 on the surface of the fixed plate 6 is started, and the output shaft of the motor 787 drives the circular plate 786 to rotate at the bottom of the fixed plate 6. When the circular plate 786 rotates, the movable rod 785 hinged on the surface of the circular plate 786 will be folded, and the folded movable rod 785 pushes the slider 784 to slide at the bottom of the fixed plate 6. When the slider 784 moves, the vertical rod 782 fixed on the surface of the slider 784 can drive the cross bar 77 to move stably laterally in the two groups of support blocks 781. When the cross bar 77 moves, the push rod 76 hinged on the surface of the cross bar 77 can be folded to push the moving block 72 to slide in the limit frame 74 under the support of the spring 73. When the moving block 72 moves, the moving block The paddle 71 fixed on the surface of 72 is continuously moved on the surface of the sieve plate 5. Since the slider 784 is performing a transverse reciprocating motion, the paddle 71 can be continuously moved on the surface of the sieve plate 5. This method can push the aggregates gathered in the central area to various places of the sieve plate 5, so that the aggregates that meet the particle size requirements can pass through the sieve holes more quickly and smoothly, thereby improving the screening speed and efficiency. The aggregates can fall into the mixer 2 for preliminary mixing. When the slider 784 moves, the connecting rod 81 fixed on the surface of the slider 784 can drive the flat rod 82 and the knocking rod 83 to perform a synchronous transverse reciprocating motion. During the movement, the knocking rod 83 can continuously knock on the surface of the feed frame 3, and the aggregates stuck to the inner wall of the feed frame 3 can fall into the mixer 2 due to vibration. This method can avoid wasting resources and avoid uneven aggregate proportions.
