Embodiment Construction
[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0028] see figure 1 , The present invention provides a crushing device for civil and construction waste, including a hoisting block 1 , a height adjuster 2 and a squeeze crushing assembly 3 .
[0029] The height adjuster 2 includes a fixed part and a telescopic part which are movably socketed with each other;
[0030] The hoisting block 1 is provided with a hoisting hole 11, and the whole device can be hoisted to the working position by a small crane during work, which is flexible and convenient to use. The height regulator 2 is used for fine-tuning the working height of the extrusion crushing as...

The invention relates to the technical field of civil construction waste treatment devices, and provides a civil construction waste crushing device which comprises a hoisting block, a height adjuster and an extrusion crushing assembly. The height adjuster comprises a fixed part and a telescopic part movably connected in a sleeving way; the fixed part is fixed to the lower part of the hoisting block; the telescopic part is fixedly connected with the extrusion crushing assembly; a vibration assembly is further arranged on a cross beam, and comprises a vibration rod arranged on the fixed block; and extrusion cylinder and an extrusion plate apply an extrusion force; and an excitation force is provided through the vibration assembly pressed on the surface of a waste. Microcracks in the waste are extended under the effect of the excitation force, and the whole waste is promoted to be crushed through the external extrusion force. The crushing process adopts cleavage fracture so as to be high in crushing efficiency and little in on-site powder dust. The civil construction waste crushing device provided by the invention can be matched with a small crane for use, is convenient and flexible in operation, and can be applicable to multiple working occasions. The civil construction waste crushing device can be used as a pretreatment process of crushing equipment and can be further used for independently accomplishing the crushing operation.
Description
technical field [0001] The invention belongs to the technical field of civil engineering and construction waste processing devices, and in particular relates to a civil engineering and construction waste crushing device. Background technique [0002] With the increase of construction projects, more and more solid wastes are produced, so the disposal of construction waste becomes a problem. [0003] The process of processing construction waste includes a crushing process. Also have a lot of relevant processing equipments at present, as the patent No. CN107096626A, CN107552206A and CN204768881U disclose the crushing device of construction waste respectively. [0004] However, limited by the size of the feed inlet, the size of the waste blocks processed by these devices is limited. Large pieces of waste need to be pre-cut into smaller pieces for disposal. Limit the range of use of these devices. [0005] In summary, there are obviously inconveniences and defects in the actu...
