The arc surfaces of one side of adjacent sieve bars 62 are in contact with one side plane, forming a gap between adjacent sieve bars 62 to sieve and drop the crushed construction waste for recycling; among them, the size of the gap between adjacent sieve bars 62 is related to the angle of the arc surface of the sieve bars 62. By designing sieve bars 62 with different arc surface angles, the particle size of the crushed construction waste can be controlled. It can be seen that the sieve bars 62 of the sieve plate adopt a single-strip filling and installation design, which is convenient for loading, unloading and replacement.

[0041] As can be seen from the above, compared with the prior art, the utility model has a light and simple structure, is easy to use, and is convenient to be designed as a small crusher for being carried and used at a construction site at any time.

[0042] The specific usage mode and function of this embodiment are as follows:

[0043] At a construction site, the utility model is moved to the position where construction waste needs to be crushed at the construction site by manual handling or by pushing with the aid of walking wheels. Then, the driving device 2 is started, and through the transmission of the transmission device 3, the hammer head 53 is driven to rotate at a high speed, and the baffle 413 is rotated upward to be opened, so that the baffle 413 is rotated and fixed above the feeding part 412. After that, construction waste is manually put into the bin body 4 by means of tools through the feeding port 401. The construction waste put into the bin body 4 is continuously crushed under the high-speed rotation of the hammer head 53 until it is crushed into small particles or powders that can pass through the gaps between the sieve bars 62, falls from the filtering component 6, and is discharged out of the crusher through the discharge port 402 and the opening of the base 1 in sequence, and then is manually collected for recycling.
