Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a building material crusher for construction. Background Art

[0002] Construction waste crushing refers to the process of crushing construction waste. Construction waste includes concrete, bricks, wood, metal, glass, plastic and other wastes generated during the construction process. The main purpose of construction waste crushing is to reduce the volume of waste and facilitate transportation and treatment. The crushed construction waste can be used for recycling, such as as recycled aggregate in the production of concrete products, or as cover layer of landfills and other construction waste.

[0003] During the crushing and recycling process of construction waste, non-metallic materials such as concrete bricks need to be separated from metal materials. The common separation method is to conduct secondary screening of the crushed materials after all the crushing is completed to achieve the purpose of separation. The overall operation steps are relatively large, which is not conducive to efficient construction material crushing and processing. Secondly, during the crushing process, construction waste such as concrete will inevitably raise a lot of dust. Utility Model Content

[0019] Example 1

[0020] See also Figure 1 The utility model provides a construction material crusher, comprising a crusher body 1, an inclined discharging barrel 2 is provided at the lower end of the crusher body 1, the discharging barrel is inclined, and its inclination angle is generally between 30° and 60°. This angle range can not only ensure that the material slides smoothly under the action of gravity, but also effectively control the sliding speed. At the same time, it can increase the contact area of ​​the magnetic plate, and the metal parts will remain on the buffer layer due to the adsorption of the magnetic plate. A through channel is provided on one side wall of the inclined discharging barrel 2, and a rubber ring is provided at the edge of the channel. When the flap 3 is closed, the rubber ring can block the gap between the channel and the flap 3. The flap 3 is rotatably provided in the channel, and the middle part of the flap 3 is rotatably connected to the channel. One side surface of the flap 3 is a buffer layer.

[0021] The buffer layer is made of wear-resistant rubber material, which can not only effectively cushion the impact of materials on the flap, extend the service life of the flap 3, but also prevent the materials from generating excessive dust and noise when impacting;

[0022] A slot is provided in the middle of the flap 3, into which the magnetic plate is inserted;

[0023] A nozzle 4 is fixedly provided at the middle of a side wall of the discharge barrel 2 opposite to the channel, and an outlet end of the nozzle 4 faces the middle of the discharge barrel 2 .

[0024] As the material is crushed and conveyed in the crusher, it is discharged outwards through the inclined discharge barrel. During the material discharge process, dust will be generated due to the collision, friction and falling of the material. After the nozzle is turned on, water or dust suppressant is sprayed from the nozzle through the pipe towards the area in the discharge barrel where the material raises dust, effectively reducing the harm of the dust generated during the crushing operation to the environment and operators, while ensuring the normal operation and work efficiency of the equipment.

[0025] An elastic clamp is provided at the open end of the slot, and the elastic clamp is used to fix the magnetic plate inserted into the slot.

[0026] The elastic clamp can tightly fix the magnetic plate inserted into the slot to prevent the magnetic plate from accidentally falling off due to vibration or other reasons during the operation of the crusher, thereby ensuring that the magnetic plate can stably play its role in absorbing metal impurities.

[0027] A latch is fixedly provided on a side wall of the flap 3 facing away from the buffer layer, and a buckle matched with the latch is provided on the outer side of the discharge cylinder 2 .

[0028] The inner diameter of the buckle is slightly larger than the diameter of the pin, generally 0.5mm-2mm larger. When the flap blocks the channel, the pin can be accurately inserted into the buckle, firmly fixing the flap in this position, preventing the flap from accidentally shaking or moving when it does not need to be rotated, and ensuring the stability and safety of the equipment during operation.

[0029] The nozzle 4 is connected to an external water supply unit through a pipeline, and a valve is provided on the pipeline.

[0030] A handle is fixedly provided on the side of the flap 3 facing away from the buffer layer.

[0031] When the utility model is used, after the material containing metal parts is crushed by the crusher body 1, the metal parts will remain on the buffer layer due to the adsorption of the magnetic plate. After one crushing is completed, the flap 3 is turned 180 degrees so that the buffer layer faces outward, and the magnetic plate is taken out. The metal fragments lose their magnetic adsorption and fall off, thereby achieving the effect of separation. At the same time, the purpose of dust reduction is achieved through the built-in nozzle.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
