[0033] See also Figure 4 Finally, the abutment plate 14 of the present invention is in an arc shape on one side adjacent to the opening 9 , and the arc shape facilitates the placement of the screen 10 .

[0034] The working principle of this utility model:

[0035] First, the staff needs to open the baffle 8 and install the screen 10. By squeezing one end of the screen 10 against the arc-shaped side of the abutment plate 14, the abutment plate 14 is displaced away from the screen 10, causing the spring 13 and the telescopic rod 12 to deform, and the reaction force of the spring 13 will squeeze the screen 10 to limit the screen 10. After the screen 10 is placed, the baffle 8 is lowered and the drive motor 18 is turned on. The drive motor 18 drives the rotating shaft 5 and the meshing teeth 7 to rotate, and the meshing teeth 7 drives another set of meshing teeth 7 to rotate, thereby realizing the rotation of the two sets of crushing rollers 6. Then, the sand and gravel to be crushed are put into the sand making machine body 1 through the feed port 2, and passed through the crushing rollers 6. After that, the sand and gravel will be crushed and then fall onto the screen 10. Under the gravity of the falling sand and gravel, the screen 10 will vibrate under the influence of the spring 13, and then vibrate the sand and gravel that meet the specifications into the collection box 15. In the collection box 15, since the mesh size of the filter 16 is smaller than the mesh size of the screen 10, the sand and gravel of smaller specifications that fall through the mesh of the screen 10 will fall to the bottom of the collection box 15, avoiding the collection of sand and gravel that meet the specifications with impurities. After the crushing is completed, there are still sand and gravel of larger specifications on the screen 10. At this time, the baffle 8 is opened. Since the height of the opening 9 is greater than the height of the screen 10, the staff can take out the screen 10 and the sand and gravel of larger specifications on the screen 10 together. At the same time, the staff can place screens 10 of different specifications in the sand making machine body 1 as needed to complete the collection of sand and gravel of different specifications. Furthermore, since the filter screen 16 is supported by the fixing column 17 , the smaller sand and gravel at the bottom of the collecting box 15 can be cleaned after the filter screen 16 is taken out.

[0036] In summary, the utility model provides a new type of sand making machine for construction engineering, including: a sand making machine main body, a crushing assembly is provided inside the sand making machine main body, a screen is provided below the crushing assembly, and a connecting assembly is provided at the connection between the screen and the sand making machine main body; the crushing assembly includes two groups of rotating shafts arranged inside the sand making machine main body, crushing rollers arranged on the two groups of rotating shafts, and a driving motor connected to the end of one group of rotating shafts and fixedly arranged on the outside of the sand making machine main body, and the rotating shaft and the crushing roller are driven to rotate by the driving motor, thereby realizing the crushing of sand and gravel; the connecting assembly includes a groove arranged inside the sand making machine main body, several groups of fixed seats symmetrically fixed in the groove, a telescopic rod fixed on the fixed seat, and an abutment plate fixed at the end of the telescopic rod, and the installation and disassembly of the screen is realized by the connecting assembly, and the screen is limited. In summary, the utility model realizes the crushing of sand and gravel through a crushing assembly, the screen can be installed through the opening, and the abutment plate is in an arc shape, which is convenient for placing the screen. When the screen is placed, it will squeeze the springs and the telescopic rods in the upper and lower positions, so that the springs generate a restoring force to limit the screen, and the crushed sand and gravel will vibrate under the action of the spring when falling onto the screen, and the crushed sand and gravel can be screened at the same time, so that the sand and gravel that meet the specifications of the screen fall into the collection box, and then the small-sized sand and gravel are filtered through the filter in the collection box and fall to the bottom of the collection box, and the sand and gravel that meet the specifications fall above the filter, which is convenient for collecting the sand and gravel that meet the specifications, and the sand and gravel that do not meet the specifications on the screen can be taken out together when the screen is taken out through the opening.
