The concrete falling between the rotating rod and the side wall of the box is not easy to be crushed by the plate hammer, which may easily cause some concrete test blocks to be difficult to be broken. Utility Model Content

[0005] In order to improve the problem that some concrete test blocks are difficult to be crushed, the present application provides a concrete test block crushing device.

[0006] The concrete test block crushing device provided in this application adopts the following technical solution:

[0007] A concrete test block crushing device comprises a box body and a crushing assembly, wherein a feed port is provided on the top of the box body, the bottom wall of the box body is inclined, a discharge port is provided on the lower side of the bottom wall of the box body, the crushing assembly comprises two crushing shafts and two crushing members, the two crushing shafts are horizontally rotatably connected in the box body, the two crushing shafts rotate toward one side close to each other, a crushing gap is formed between the two crushing shafts, the two crushing shafts are used to crush concrete test blocks, the two crushing members are fixed to the box body, one crushing member is connected to one crushing shaft, and the crushing member is used to drive the crushing shafts to rotate;

[0008] The box body is connected to a guide plate on both sides of the feed port, and the guide plates are arranged downwardly from the top wall of the box body toward the crushing axis. The two guide plates are arranged inclined toward each other, and the two guide plates form a guide gap away from the top wall of the box body. The guide gap corresponds to the crushing gap, and the guide plates and two opposite side walls of the box body form a gathering area.

[0009] By adopting the above technical solution, when the concrete test block crushing device is needed, first, the concrete test block crushing device is fixed, and the two crushing parts are started at the same time. The crushing parts can drive the crushing shaft to rotate. Then, the concrete test block to be crushed is poured into the box through the feed port, and the concrete test block can fall into the crushing gap. At this time, the crushing shaft crushes the concrete test block, and the crushed concrete test block can fall to the bottom wall of the box through the crushing gap, and then is discharged through the discharge port. In the process of pouring the concrete test block into the box, the concrete test block slides along the guide plate into the crushing gap, and the concrete is crushed by the crushing shaft. The soil test block is crushed by setting a drainage plate. On the one hand, the concrete test block falls into the crushing gap along the drainage plate, which is beneficial to reduce the situation where the concrete test block is scattered into the blocking gap; on the other hand, when the crushing shaft crushes the concrete test block, dust can be generated. The drainage plate is tilted, and the drainage plate and the side wall of the box form a gathering area, which is beneficial to reduce the discharge of dust through the feed port; compared with the related art, the present application sets a drainage plate, so that the concrete test block can fall into the crushing gap along the surface of the drainage plate, and the concrete test block is crushed by the crushing shaft, which is beneficial to improve the problem that some concrete test blocks are not easy to be crushed.

[0010] Optionally, two blocking components are further included, and the two crushing shafts form a blocking gap on one side away from each other and close to the side wall of the box body, and one blocking component corresponds to a blocking gap. The blocking component includes a fixed frame, a blocking plate, a power member and a flipping member. The fixed frame is fixed to the inner wall of the box body, and the blocking plate is horizontally slidably arranged on the side of the fixed frame close to the top wall of the box body. A rotation gap is left between the blocking plate and the crushing shaft, the power member is connected to the fixed frame, and the power member is connected to the blocking plate to drive the blocking plate to move toward or away from the fixed frame, and the blocking plate is used to block concrete test blocks. The flipping member is connected to the fixed frame, and the flipping member is connected to the blocking plate to drive the flipping member to flip toward the crushing shaft.

[0011] By adopting the above technical solution, when it is necessary to pour the concrete test blocks into the box. In the process of pouring the concrete test blocks into the box, the concrete test blocks fall into the crushing gap along the drainage plate, and the crushing shaft crushes the concrete test blocks poured into the box first. Subsequently, the concrete test blocks that have not yet fallen into the crushing gap may collide with the concrete test blocks that have already fallen into the crushing gap, causing the concrete test blocks that have not yet been crushed to scatter into the blocking gap. At this time, the concrete test blocks scattered into the blocking gap fall on the blocking plate. After the remaining concrete test blocks are crushed for a period of time, the pouring of the concrete test blocks is stopped, and then the power part is turned on, and the power part drives the blocking plate to move toward the top wall of the box. When it moves to a certain position, the flip part is started again, and the flip part drives the blocking plate to move. The plate flips over, at this time, the concrete test blocks on the barrier plate fall into the crushing gap and are crushed by the crushing shaft. After all the concrete test blocks on the barrier plate fall into the crushing gap, the flipping part is started again, the barrier plate is adjusted to a horizontal position, the power part is turned on, and the power part drives the barrier plate to move away from the top wall of the box body until the next use. By setting the blocking component, the barrier plate blocks the concrete test blocks. After the remaining concrete test blocks are crushed, the power part and the flipping part are started again, so that the concrete test blocks on the barrier plate fall into the crushing gap, and the concrete test blocks on the barrier plate are continuously crushed by the crushing shaft, which is further conducive to improving the problem that some concrete test blocks are not easy to be crushed.

[0014] By adopting the above technical solution, when the concrete test block on the blocking plate needs to fall into the crushing gap, the concrete test block that has fallen into the crushing gap is crushed, and the pouring of the concrete test block is stopped. Thereafter, multiple first cylinders are started at the same time, and the first cylinder drives the blocking plate to move toward the side close to the top wall of the box body. At this time, the concrete test block on the blocking plate moves with the blocking plate. During this process, the hinged seat moves on the blocking plate in the direction away from the crushing axis. When it moves to a suitable position, the first cylinder is closed, and the second cylinder is started at the same time. The second cylinder pulls the blocking plate to rotate around the piston rod of the first cylinder, and the blocking plate rotates toward the side close to the crushing axis. At this time, the blocking plate is in an inclined state, and the concrete test block on the blocking plate slides into the crushing gap. The concrete test blocks are crushed by the crushing shaft. When all the concrete test blocks on the barrier plate fall into the crushing gap, multiple second cylinders are started at the same time. The second cylinders push the barrier plate to move away from the crushing shaft, so that the barrier plate is in a horizontal state. The first cylinder is started at the same time. The first cylinder drives the barrier plate to move away from the top wall of the box body. At this time, the hinged seat moves toward the direction close to the crushing shaft until the next use. By setting the first cylinder and the second cylinder, on the one hand, it is conducive to realizing the automation of operation; on the other hand, the first cylinder and the second cylinder are used together to facilitate the concrete test blocks on the barrier plate to slide into the crushing gap, and the concrete test blocks are crushed by the crushing shaft, which is convenient for improving the problem that some concrete test blocks are not easy to be crushed.
