[0029] Traditional pulverizers generally use alloy crushing teeth that mesh with each other to crush the material into small pieces of waste, but such small pieces of waste are still inconvenient to collect and recycle quickly; at the same time, the alloy crushing teeth of traditional pulverizers have a certain spacing, and they cannot evenly screen and collect the material.

[0030] To solve the above disadvantages of traditional technology, please refer to Figure 1-5 , the utility model provides a technical solution: a material crushing device for construction engineering, comprising a crusher 1;

[0031] Among them, the crusher 1 is a traditional alloy crusher, which is responsible for pre-crushing the material from a large block into several small blocks;

[0032] The crusher 1 is placed on the top of all other devices, and a screening mechanism 2 is installed at the discharge port of the crusher 1; at the same time, the screening mechanism 2 is used to screen the material crushed by the crusher 1 and evenly place it in the pressing mechanism 3; the pressing mechanism 3 includes three linear degrees of freedom, and presses the upper crushed material into blocks through the three linear degrees of freedom.

[0033] In some specific embodiments of this application, please refer to Figures 1 to 3 The screening mechanism 2 includes a power member 201, a screening shaft assembly driven by the power member 201, and a frame 205; the top of the frame 205 is connected to the crusher 1, the number of the screening shaft assemblies is at least three groups, and they are rotatably fitted in the frame 205 in a symmetrical manner.

[0034] The screening mechanism is mainly used to screen the small pieces of material crushed by the upper crusher 1 uniformly, and let them fall into the pressing mechanism 3 by gravity for pressing;

[0035] In this embodiment, the screen shaft assembly includes a transmission shaft 202, a groove wheel 203 fixedly connected to the transmission shaft 202, and a chain shaft 204 arranged in a circular array outside the groove wheel 203; the chain shaft 204 of one screen shaft assembly engages with the wheel groove of the groove wheel 203 of another screen shaft assembly.

[0036] Through the above-mentioned matching mode, one of the transmission shafts 202 is driven to rotate by the power member 201, and the transmission shaft 202 drives the groove wheel 203 and its chain shaft 204 to rotate. At the same time, based on the rotation of the chain shaft 204, the groove wheels 203 of other screen shaft assemblies are driven to rotate;

[0037] Based on the above, within the area of ​​the frame 205, the multiple groups of chain shafts 204 rotate continuously, and through the characteristics of the long rods, the small pieces of material on the top are output downward according to the rotation frequency, so as to achieve uniform screening.

[0043] After the above pressing and forming, the material is pressed into a solid block;

[0044] In this scheme, the above pressing process needs to be pressed in a certain order; among them, the long end of the material needs to be pressed first, then the high end of the material needs to be pressed, and finally the short end of the material needs to be pressed;

[0045] The first telescopic cylinder 302 driven by the short end and its first pressing plate 303 are adapted to the positions of the door body 3011 detachably connected to the outer surface of the box body 301 , and the door body 3011 is responsible for opening and closing the box body 301 .
