Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering equipment, in particular to a recycled concrete hollow block cutting device. Background Art

[0002] Recycled concrete is a concrete material made by re-compressing and mixing waste concrete. It is often used to make building blocks and other building components that do not require high compressive strength and are not on the surface of the building. Hollow blocks made of recycled concrete are cheaper and still have a certain compressive strength. Therefore, they can be widely used in the construction of non-load-bearing walls. Concrete hollow blocks are usually cut by cutting machines. For example, the existing HQP-150 cutting machine can perform wet cutting quickly, which is convenient for temporary processing of block sizes at the construction site, and thus facilitates the construction of blocks.

[0003] According to the patent publication number CN218776890U: The utility model relates to the field of concrete technology, and discloses a construction concrete block cutting device, including a cutting machine body, one side of the bottom of the cutting machine body is fixedly connected to one side of the main shell, the back of the main shell is fixedly connected to one side of the motor, the output shaft of the motor is fixedly plugged into the axis of the rotating wheel, the middle of the rotating wheel is rotatably connected to the bottom of the main shell, and the eccentric part of the front of the rotating wheel is fixedly connected to the back of the eccentric transmission column. The construction concrete block cutting device controls the rotation of the rotating wheel through the motor, and controls the left and right movement of the spur gear through the eccentric transmission column and the transmission rod, so that the concrete blocks can be driven into the cutting machine at a uniform speed for cutting operation without manual hand support, effectively avoiding the safety hazards caused by hand-held cutting, and solving the problem that the traditional concrete block cutting device needs to manually push the blocks for cutting operation, which is extremely risky for the operator.

[0004] However, the fixed plate in the above patent can only be used to clamp blocks of fixed size, so it cannot effectively clamp blocks of different sizes, which makes the blocks easy to shake with cutting, and then causes the cutting position to deviate and cause errors in the size of the blocks after cutting. In addition, most of the existing recycled concrete hollow block cutting devices are provided with movable moving wheels, but most of the existing concrete block cutting machines have no fixed structure. Therefore, the equipment is easy to be accidentally touched during operation, resulting in autonomous movement, which makes it difficult for the staff to hold the blocks firmly, and thus causes errors in cutting the blocks. Utility Model Content
