Description

Technical Field

[0001] The utility model belongs to the technical field of concrete, and in particular relates to a raw material preparation machine for concrete preparation. Background Art

[0002] Concrete refers to an artificial stone made of cement as the main cementitious material, mixed with water, sand, gravel and other raw materials in appropriate proportions, and then evenly mixed, compacted and hardened. Concrete has abundant raw materials, such as coal gangue, gypsum, lime blocks and other materials with a certain hardness. In order to ensure the quality of concrete, the required raw materials usually need to be pre-processed before concrete preparation.

[0003] The existing concrete raw material crushing equipment has problems such as low crushing efficiency and poor crushing effect, and it is difficult to meet the growing production demand. In response to the above technical problems, the applicant has retrieved some prior arts, such as the Chinese patent with patent publication number CN208679255U. When in use, the material is crushed by a crushing roller, but the crushing roller only has a simple extrusion effect when crushing the material. At the same time, the contact time between the material and the extrusion roller is short, and thus some material may pass through the extrusion rollers without being crushed, reducing the crushing effect. Summary of the invention

[0004] The utility model aims to provide a raw material preparation machine for concrete preparation, aiming to solve the technical problem in the prior art that simple extrusion and crushing of materials leads to poor material crushing effect.

[0005] The utility model is implemented as follows: a raw material preparation machine for concrete preparation comprises a shell, a conduit is fixedly mounted on the shell, the conduit passes through the side wall of the shell and one end of the conduit located in the shell is fixedly connected to a top plate, the shell is provided with a bottom plate and a telescopic member for driving the bottom plate to move is provided in the shell, a vertical pipe is fixedly mounted on the bottom plate, a pressure plate is rotatably mounted on the vertical pipe, and a power component for driving the pressure plate to rotate is provided on the bottom plate.

[0006] Further technical solution: one end of the conduit located outside the shell is connected to a feed hopper.

[0007] Further technical solution: A conical head is fixedly installed at one end of the vertical pipe away from the bottom plate, and a plurality of groups of air holes distributed in a circular array around the vertical pipe are arranged on the conical head, and the air holes are connected with the vertical pipe.

[0008] Further technical solution: A fan for conveying air into the vertical pipe is fixedly installed on the bottom plate.

[0009] Further technical solution: The connection position between the conduit and the top plate is set as a conical structure and is used in conjunction with a conical head.

[0010] Further technical solution: A protective ring coaxially arranged with the vertical pipe is fixedly installed on the bottom plate.

[0011] Further technical solution: the power assembly includes a rotating power part, which is fixedly mounted on the base plate and drives a gear to rotate, and the gear is meshed with a gear ring fixedly mounted on the pressure plate.

[0012] Further technical solution: The axis of the gear ring is coaxially distributed with the rotation axis of the pressure plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The pressing plate and the top plate rotate relative to each other, so that the material on the pressing plate can roll, changing the placement state of the material. With continuous pressure, the material will be easier to crush into powder, thereby improving the crushing effect of the material.

[0015] 2. During crushing, a layer of material is distributed on the pressure plate, which avoids the accumulation of a large amount of material, resulting in the internal material not being directly squeezed during extrusion, increasing the force strength of the material and improving the crushing effect of the material.

[0016] 3. The ejected air flows along the pressing plate to blow the crushed powdered material outwards to avoid residual powdered material on the pressing plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In actual application of this embodiment, the material to be crushed is put into the conduit 2 through the feed hopper 3, the material falls in the conduit 2 and is evenly dispersed on the pressing plate 14, at this time, the telescopic member 5 drives the bottom plate 6 to move upward, and then the pressing plate 14 moves upward, and the pressing plate 14 moves upward to cooperate with the top plate 4 to squeeze the material on the pressing plate 14, and at the same time, the power component 16 drives the pressing plate 14 to rotate slowly, and the pressing plate 14 and the top plate 4 rotate relative to each other so that the material on the pressing plate 14 can roll, changing the placement state of the material, and with continuous pressurization, the material will be easier to crush and grind into powder, thereby improving the crushing effect of the material. After the crushing is completed, the telescopic member 5 contracts to move the pressing plate 14 downward, and the power component 16 accelerates the rotation of the pressing plate 14, so that the crushed material is scattered around under the action of centrifugation, and the above steps are repeated to continue the crushing operation of the material. During crushing, a layer of material is distributed on the pressing plate 14, which avoids the accumulation of a large amount of material, resulting in the internal material not being directly squeezed during extrusion, increasing the force strength of the material, and improving the crushing effect of the material.

[0025] In an example of this embodiment, the telescopic member 5 is an electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder.

[0029] Specifically, a protective ring 15 coaxially arranged with the vertical pipe 7 is fixedly mounted on the bottom plate 6 .
