[0023] Generally, when screening mortar, it is necessary to screen out coarse sand and large impurities such as crushed stone and mud, so as to improve the quality of mortar. However, most of the mortar screening devices in the prior art are primary screening, which leads to incomplete screening of mortar and reduces screening efficiency.

The other ends of the two first screens 7 are both inclined downward and are respectively connected to the two first discharge ports 8. The outer wall of the device body 1 is provided with a first collecting box 25 matching the first discharge port 8. Specifically, after the raw material passes into the inner cavity of the device body 1 through the feed port 5, it falls on the two symmetrically arranged first screens 7, and the screened impurities flow along the inclined first screens 7 toward the first discharge port 8 until they fall into the first collecting box 25 for collection;
[0025] The second screening mechanism includes a second screen 9 fixed to the side wall of the inner cavity of the device body 1, and a second discharge port 10 opened on the side wall of the device body 1, one end of the second screen 9 is fixed to the inner wall of the device body 1, and the other end of the second screen 9 is inclined downward and communicated with the second discharge port 10, and the outer wall of the device body 1 is provided with a second collecting box 11 matching the second discharge port 10. Specifically, the raw material after the first screening and impurity removal falls onto the second screen 9, and the second screening and impurity removal is carried out. The screened impurities then fall from the second discharge port 10 along the inclined second screen 9 to the second collecting box 11 for collection.
[0026] Furthermore, the third screening mechanism includes a sliding rod 12 symmetrically fixed to the inner wall of the device body 1, and a sliding sleeve 13 is provided on the sliding rod 12.

The first cam 17 will intermittently push the device body 1 to move rightward on the bottom plate 2. Under the elastic force of the compression spring 21, the device body 1 will rebound to the left, and this cycle will be repeated to realize the horizontal movement of the device body 1 and improve the screening and impurity removal efficiency.
[0028] Furthermore, a second cam 22 is connected to the rotating rod 20 located in the inner cavity of the device body 1, and one end of the second cam 22 contacts the bottom of the third screen 14.

[0030] Furthermore, the apertures of the first sieve 7, the second sieve 9, and the third sieve 14 are arranged from large to small. Specifically, the apertures are arranged from large to small so that the raw materials can be fully screened and impurities and stones of different sizes can be screened out.
[0031] It can be known from the above technical scheme that when in use, the raw material is passed into the inner cavity of the device body 1 through the feed port 5 opened at the top of the device body 1, and then falls onto the two first sieves 7 symmetrically arranged, and the sieved impurities flow along the inclined first sieve 7 to the first discharge port 8 until they fall into the first collecting box 25 for collection, and the raw material after the first screening and impurity removal falls onto the second sieve 9 for the second screening and impurity removal, and the sieved impurities then fall from the second discharge port 10 along the inclined second sieve 9 to the second collecting box 11 for collection, and the high-pressure air pump 23 is started to spray gas from the high-pressure air pipe 24 to purge the impurities remaining on the second sieve 9 that have not completely fallen into the second collecting box 11, so as to avoid blocking the second sieve 9 and affecting the impurity removal effect, and the raw material after the second screening and impurity removal falls onto the third screening mechanism again, and is subjected to the third screening and impurity removal, which fully achieves comprehensive impurity removal and thorough impurity removal;

Under the elastic force of the compression spring 21, the device body 1 will rebound to the left, and in this way, the device body 1 can move horizontally. When the second bevel gear 19 drives the rotating rod 20 to rotate, the second cam 22 will also intermittently move the third screen 14 up and down under the cooperation of the sliding sleeve 13 and the sliding rod 12, and finally discharge it through the discharge port 6 opened at the bottom of the device body 1, which solves the problem that when screening mortar, coarse sand, crushed stone, mud and other large impurities need to be screened out, thereby improving the quality of mortar. However, most of the mortar screening devices in the prior art are primary screening, which leads to insufficient screening of the mortar and reduces the problem of screening efficiency.
