Fig. 1 shows the realization form of a crushing device for concrete production according to the present invention, which includes a crushing mechanism 1 and a dust removal mechanism 2 arranged at the discharge end and/or the feeding end of the crushing mechanism. The material side is provided with a rolling mechanism 3 in a horizontal layout. In this structure, through the design of the rolling mechanism, the material diameter entering the crushing mechanism can be crushed in the early stage, so that it can change from a large block to a crushing mechanism. Small pieces are more conducive to the crushing operation of the crushing mechanism. In practical application, the crushing mechanism can use roller crushing or centrifugal crushing. No matter what kind of crushing method is used, its rear end needs to be set to match. The dust removal mechanism can reduce the dust. The dust removal mechanism can adopt a bag type structure or a suction filter type structure. Further, the outside of the rolling mechanism and the side that cooperates with the crushing mechanism can use the same type. The disassembled cover is sealed to ensure the tightness of its work, further reduce its dust, and meet the needs of environmental pollution control during industrial production;

Wherein, the rolling mechanism is configured to include:

The chain plate type transmission mechanism 4 in a horizontal layout adopts a rolling plate type structure, so that the sealing degree is better, the fine materials will not fall through the gap, and the stability of the structure is better. When the roller is rolling, it has better supporting force and will not affect its transmission;

A plurality of rolling rollers 5 are arranged above the chain plate transmission mechanism, and the distance between each rolling roller in the output direction of the material and the chain plate transmission mechanism is arranged in decreasing order. In this structure, the material is transmitted through the chain plate type. The mechanism is transported along its moving direction. When entering the most front rolling roller, the rolling roller with the largest spacing is used for initial rolling, and its size is preliminarily controlled, and then the particle size is further passed through the subsequent rolling rollers. Further adjustment is made to make the material diameter of the material input to the crushing mechanism at the rear end more controllable, which is more conducive to industrial production. Further control is carried out by manual operation, or a matching baffle plate is set for auxiliary feeding to prevent damage to personnel caused by manual operation.

As shown in Figure 1, in another example, the material output end of the rolling mechanism is communicated with the feeding hopper 7 of the crushing mechanism through a matching vertical or inclined lifting mechanism 6, and the materials processed by the rolling mechanism pass through the vertical or The inclined lifting mechanism is used for conveying to realize automatic operation, and the choice of vertical or inclined lifting mechanism can be adjusted according to the needs of the site layout, while the vertical lifting mechanism adopts a Z-shaped vertical bucket elevator, and its internal transmission is configured as a screw type The structure of , because the structure is in the prior art, it will not be described here.

As shown in Figure 1, in another example, a plurality of first crushing teeth 8 are arranged on the outer circumference of each rolling roller, and the structure of the material is processed by the outer first crushing teeth, so that the material can be transferred during the transfer process. Crushing not only depends on the rolling operation of the rolling roller, but also can crush the material through the crushing teeth, and the processing efficiency and processing strength are more controllable.

As shown in Figure 1-2, in another example, the rolling mechanism is configured to further include a temporary storage bucket 9 disposed at the output end of the chain-plate transmission mechanism, which is used for buffer processing of materials. In specific applications, The temporary storage bucket can be set above the vertical lift upper machine in space, or can be set on one side of it, and the specific location design can be carried out according to the needs of the site;

Wherein, two first crushing rollers 10 are oppositely arranged inside the temporary storage bucket at positions matched with the output end of the chain plate type transmission mechanism, and the distance between the first crushing rollers is configured to be 1-3 cm. In practical application, the material output from the chain plate transmission mechanism enters the position of the first crushing roller, and the size is further controlled by secondary treatment with the first crushing roller. The motor connected to the crushing roller can be one or two. If it is one, the moving crushing roller and the static crushing roller will cooperate with each other to complete the processing of the material. The rotation direction can be set in the opposite state, so that the material will not move or rotate between the crushing rollers, which will affect its crushing efficiency. The spacing can be set according to the actual application scene to have better adaptability.

As shown in Fig. 1-2, in another example, below the first crushing roller and at the position matched with the inner wall of the temporary storage bucket, there are respectively arranged second crushing rollers 11 in the same layout direction as the first crushing roller, In actual operation, after the material falls into the temporary storage bucket, some materials cooperate with the first crushing roller to complete the crushing operation, but some materials will be separated from the first crushing roller and the temporary storage due to the rotation of the first crushing roller. The gap between the buckets falls, which affects the uniformity of the size of the material, and a matching second crushing roller is set below to process the falling material in space, relative to the distance between the first crushing roller and the side wall In terms of reduction, layered processing can be formed to increase efficiency;

Among them, the inner wall of the temporary storage bucket is provided with a crushing plate 12 in a detachable manner at the position matched with the second crushing roller. The operation generated by the inner wall is designed in a detachable way, so that it can be replaced as needed during later maintenance;

On the outer periphery of the first crushing roller and the second crushing roller, a plurality of matching second crushing teeth 13 are respectively arranged on the side where the crushing plate and the second crushing roller are matched. The crushing effect and efficiency of the material and the sharpness of the top of the second crushing teeth can be significantly reduced compared to the first crushing teeth. In addition, the second crushing roller and rolling roller in this solution are of course provided with The matching transmission motor, and the position where the temporary storage bucket or other structures are matched are naturally provided with holes for installation, and at the same time, the bearing seat is matched to ensure the stability and reliability of its operation.

Each of the above solutions is only an illustration of a preferred example, but is not limited thereto. When implementing the present invention, appropriate replacements and/or modifications can be made according to user needs.

The number of equipment and processing scale described here are intended to simplify the description of the present invention. Applications, modifications and variations to the present invention will be apparent to those skilled in the art.

Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. It can be completely applied to various fields suitable for the present invention. Additional modifications can readily be implemented by those skilled in the art. Therefore, the invention is not limited to the specific details and illustrations shown and described herein without departing from the general concept defined by the claims and the scope of equivalents.
