Description

Technical Field

[0002] Concrete refers to an artificial stone material made by mixing cement, water, sand, gravel, chemical admixtures and mineral admixtures in appropriate proportions, and then uniformly mixing, compacting, and curing and hardening. Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture; the hard state after hardening, that is, hardened concrete or concrete. The particle size of sand and gravel has a greater impact on the strength of concrete. The finer the sand and gravel, the higher the strength of concrete. Therefore, before making concrete, it is necessary to screen the sand and gravel so as to grade and make concrete of different strengths.

The connecting rod 410 is fixedly connected to both sides of the storage box 411. By connecting the storage box 411 and the lifting cylinder 47 with the connecting rod 410, the storage box 411 is lifted and lowered by the lifting cylinder 47. A reset spring 491 is arranged inside the reset sleeve 49, and the reset spring 491 is wound around the outer wall of the connecting rod 410. Both ends of the reset spring 491 are fixedly connected to the inner wall of the reset sleeve 49.

One side of the connecting rod 410 is slidably connected to the inner wall of the arc groove 5. By making one side of the connecting rod 410 slidably connected to the arc groove 5 opened on the inner wall of the main body 1, the movement trajectory of the storage box 411 is fixedly limited. A first transmission shaft 42 is arranged above the first rotating shaft 31 and the second rotating shaft 32, and the first transmission shaft 42 and the second transmission shaft 43 are connected by a transmission belt 44.

[0026] Working principle: The motor 2 drives the first rotating shaft 31 to rotate, so that the crushing wheels 33 fixedly connected to the middle of the first rotating shaft 31 and the second rotating shaft 32 rotate in opposite directions, thereby performing the first rolling and crushing operation on the concrete. The sliding rod 35 fixedly connected to the side of the second rotating shaft 32 rotates on the inner wall of the sliding block 38 with the center of the turntable 34 as the axis, so that the L-shaped swing rod 37 drives the sub-screen plate 39 to swing back and forth in a fan shape with the side hinged to the bracket 310 as the axis, so that the concrete crushed by the crushing wheel 33 is screened, and the concrete required after screening will slide into the storage box 411 on its side through the swing of the sub-screen plate 39, and the storage box 411 is lifted and dropped vertically by the operation of the lifting cylinder 47. During the lifting process, the storage box 411 is controlled by the blocking rod 45. The obstruction of the box 411 causes it to flip in the counterclockwise direction, so that the concrete in the storage box 411 falls along the unloading plate 46 to the conveyor belt 44 below, and the first rotating shaft 31 and the first transmission shaft 42 are connected through the transmission belt 41 to make the powder screening mechanism 3 work while the conveyor belt 44 rotates counterclockwise, so that the concrete falling on the conveyor belt 44 can fall into the two crushing wheels 33 again for secondary crushing, until the crushed concrete can be screened by the sub-screening plate 39 below to meet the final production and operation requirements.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
