The blade 23 cuts the cement material, realizes the horizontal mixing and material cutting of the cement, improves the mixing effect, and drives the crushing mechanism 3 to work, which is convenient for the crushing mechanism 3 to carry out vertical stirring and grinding and crushing of sand and gravel aggregates;

Because large sand and gravel aggregates are easy to appear in the cement slurry, it is difficult to affect them by stirring, and it is easy to affect the quality of cement if they are not decomposed. Shaped gear 2 34 drives rotating rod 2 35 to rotate, and rotating rod 2 35 drives stirring blade 2 37 on rotating plate 36 to carry out vertical stirring, and two groups of rotating plates 36 mutually extrude cement by extruding block 38 and grind, realize cement Vertical mixing can enhance the mixing effect, and can squeeze and grind the cement to speed up the mixing speed of cement and the quality of finished products;

A large amount of dust will be generated during the mixing process of cement, sandstone aggregate and water. The diffusion of dust will not only pollute the environment, but also affect the health of the staff when inhaled into the human body. The dust suction port 44 sucks the dust into the dust suction channel 43, and then the hydraulic mechanism 5 sprays the dust to reduce the dust into the water tank 42, and supplies water to the water tank 42 through the water inlet pipe 45, and filters the dust through the filter screen 46 to prevent the dust from blocking the water pipe. Realize the effect of cooperating with the air induction mechanism 6 to absorb dust and the hydraulic mechanism 5 to reduce dust, so as to facilitate the collection of dust and prevent the dust from spreading;

Because the dust sucked by the air-inducing mechanism 6 is easy to flow back, it is necessary to carry out dust reduction treatment on the sucked dust. The double-headed motor 13 drives the driving pulley 514 to rotate, and the driving pulley 514 drives the driven pulley 513 to rotate through the belt, and the driven pulley 513 passes through the reciprocating screw rod. 512 drives the piston one 511 to reciprocate and drives the air-inducing mechanism 6 to drain the water. When the piston one 511 rises, the water in the water tank 42 is sucked into the hydraulic chamber 53 through the water suction pipe 54. When the piston one 511 descends, the water in the water tank 42 passes through The water delivery pipe 56 is sent to the three-way valve 57, and the three-way valve 57 can be connected to the drain pipe 58 to make the water pass through the nozzle 59 to reduce the dust in the dust suction channel 43 and transfer the quantitative mechanism 7 to quantitatively inject the solution, so as to realize the cleaning of the dust suction channel. 43 internal spraying is convenient for dust reduction, and can control the drainage of the air-inducing mechanism 6 and control the quantitative injection of the solution by the quantitative mechanism 7;

Because the floating dust is scattered to all directions, drainage is needed to suck the floating dust into the dust suction mechanism 4 for dust reduction. The reciprocating screw rod 512 drives the bevel gear 3 61 to rotate, and the bevel gear 3 61 meshes with the bevel gear Four 62 are linked, and the bevel gear four 62 drives the fan 64 to rotate through the rotating rod three 63 for drainage, so as to realize the suction of the air flow, facilitate the dust to enter the dust suction channel 43, and facilitate the follow-up hydraulic mechanism 5 to carry out the dust reduction work;

During the mixing of cement, it is often necessary to quantitatively add solvent to catalyze or adjust the concentration. The controller 14 controls the three-way valve 57 to transfer the water delivery pipe 56 to the water inlet pipe 72 so that the water flows into the injection box 71, and the piston 2 78 descends through the liquid outlet pipe 76 The solvent below the piston two 78 is quantitatively added to the device main body 1, and the backflow is prevented by the one-way valve three 77, and then the sensing valve 73 senses the set pressure and automatically opens and transmits the information to the controller 14, and the controller 14 instructs The three-way valve 57 is reconnected to the drain pipe 58, and finally the spring 79 drives the piston 2 78 to rise through the liquid inlet pipe 74 to inhale the quantitative solvent again, so as to realize the automatic injection of the quantitative solvent, facilitate the adjustment of the concentration of cement and the addition of catalysts, and improve the quality of cement production.
