[0025] First, cement and mortar are injected into the first mixing box 12 in proportion, and the first motor 5 is started. The first motor 5 can drive the first rotating shaft 13 to rotate, so that the first stirring blade 14 can rotate to stir and mix the cement and mortar first. After the stirring is completed, the second solenoid valve 15 is controlled to allow the mixed cement and mortar to flow into the second mixing box 17. This setting can evenly mix the cement and sand through stirring, avoiding the unevenness caused by traditional manual mixing.

[0026] The stirring assembly includes a second motor 7, a second rotating shaft 18 and a first gear 20. One end surface of the dustproof box 1 is fixedly connected to the second motor 7, the output end of the second motor 7 is fixedly connected to the second rotating shaft 18, one end surface of the second rotating shaft 18 is provided with a plurality of second stirring blades 19, one end surface of the second rotating shaft 18 away from the second motor 7 is fixedly connected to the first gear 20, one side outer wall of the first gear 20 is meshed and connected to the second gear 21, one end surface of the second gear 21 is fixedly connected to the third rotating shaft 22, one end surface of the third rotating shaft 22 is fixedly connected with a plurality of third stirring blades 23, the second stirring blades 19 and the third stirring blades 23 are both arranged to be symmetrical up and down, and the second stirring blades 19 and the third stirring blades 23 are staggered.

[0027] The second motor 7 drives the second rotating shaft 18 to rotate, so the second stirring blade 19 rotates, and the rotation of the third stirring blade 23 is completed by the meshing connection between the first gear 20 and the second gear 21, and the rotation is transmitted to the third rotating shaft 18. Since the second stirring blade 19 and the third stirring blade 23 are staggered and rotate in opposite directions, the cement, mortar and water can be fully mixed and stirred.

[0037] One end surface of the slide plate 9 is slidably connected to the top end of the dustproof box 1 .

[0038] This arrangement can make the slide plate 9 fit closely with the dustproof box 1 to prevent dust from entering.

[0039] Working principle: first, cement and mortar are injected into the first mixing box 12 in a certain proportion. After the injection is completed, the electric push rod 10 is started, and the electric push rod 10 pushes the slide plate 9 to cover the feed port, and the first motor 5 is started. The first motor 5 drives the first rotating shaft 13 to rotate. The first stirring blade 14 can mix the cement and mortar. After the mixing is completed, before concrete is needed, the second solenoid valve 15 is opened, and the mixture enters the second mixing box 17. Then, according to the stirring situation, water is injected at any time, and the second motor 7 is started. The second motor 7 drives the second rotating shaft 18 to rotate, so that the second stirring blade 19 rotates, and the third stirring blade 23 relies on the first gear 20 and the second gear 21 to transmit rotation. Because the second stirring blade 19 and the third stirring blade 23 are staggered, the cement, mortar and water are mixed evenly.
