Description

Technical Field

[0001] The utility model relates to the technical field of cement glue mixing, in particular to a cement mortar sand mixer. Background Art

[0002] Cement is often used in construction projects. The quality of cement is very important to the entire construction project. If the quality of cement is unqualified, using it in construction projects will cause the building quality to fail to meet the standards. Therefore, cement mortar mixers are generally used to test the quality of cement.

[0003] A Chinese utility model with authorization announcement number CN218639995U discloses a cement mortar mixer. When the device is in use, the lifting mechanism is set up and the second motor is started. Under the rotation of the second motor, the stirring blade can be driven to rotate and stir. By setting the lifting stirring blade, the cement mortar of different depths in the mixing drum can be evenly stirred, thereby improving the stirring effect. However, in the specific actual use process, when the cement slurry is stirred in the device, cement dust is easily dispersed from the surrounding air above the mixing drum. The cement dust enters the air and will be inhaled by the operator. Long-term inhalation of cement dust is harmful to health and may cause respiratory diseases. Therefore, it is necessary to redesign the cement mortar mixer in view of the above-mentioned problems. Utility Model Content

[0022] When in use, another set of connecting pipes 15 is connected to an external container with a water source. With the help of the rotation of the reciprocating screw 11, the piston 14 is driven to slide. During sliding, the external water source can be drawn into the device barrel 7, and then injected into the nozzle 10 for atomization and spraying, so as to achieve the dust reduction effect on the raised cement dust. It should be noted that when dust reduction is not needed, the connecting pipe 15 can be drawn out from the external water source.

[0023] Reference Figure 2 and Figure 3 , a reciprocating screw 11 is rotatably connected to the bottom of the device barrel 7, a screw sleeve 13 is threadedly connected to the threaded section of the reciprocating screw 11, a limit block 12 is fixedly connected to the end of the reciprocating screw 11, and the radius of the limit block 12 is greater than the radius of the reciprocating screw 11. The inner wall of the device barrel 7 and the outer walls on both sides of the screw sleeve 13 are square, and the outer wall of the screw sleeve 13 is in sliding contact with the inner wall of the device barrel 7. The lower end surface of the slide plate 3 is rotatably connected to a gear 8 and an incomplete gear 9, the gear 8 is coaxially fixedly connected to the reciprocating screw 11, the incomplete gear 9 is coaxially fixedly connected to the stirring plate 6, and the gear 8 and the incomplete gear 9 are meshed with each other. The upper end surface of the slide plate 3 is fixedly connected to a servo motor 4, and the end of the output shaft of the servo motor 4 is coaxially fixedly connected to the incomplete gear 9;

[0024] The rotation of the incomplete gear 9 can drive the reciprocating screw 11 to rotate, so as to prevent the stirring plate 6 from rotating too fast, which will cause accelerated wear of the parts of the device barrel 7. By setting the transmission ratio between the incomplete gear 9 and the gear 8, it can be ensured that the speed of the water mist sprayed by the nozzle 10 can effectively reduce the raised cement dust.

[0025] In the utility model, the specific function of the device is as follows: when in use, the mixing drum is installed on the upper end of the base 1, and the sliding plate 3 and its external components are driven to slide downward by the telescopic end of the hydraulic cylinder 2 until the provided mixing plate 6 slides into the mixing drum, and then the mixing plate 6 is driven to rotate by the servo motor 4, so as to mix the cement mortar in the mixing drum.
