Description

Technical Field

[0001] This utility model relates to the field of mixer technology, specifically to a cement mortar mixer. Background Technology

[0002] Cement mortar mixers are mainly used to mix materials such as cement and sand to produce concrete or other building materials. Their structure typically includes a dual-speed motor, sand box, transmission box, main shaft, eccentric seat, mixing blades, mixing pot, base, column, support, outer cover, and controller. Through a series of mechanical transmissions, the mixing blades revolve and rotate within the mixing pot, thereby achieving uniform mixing of the materials.

[0003] After mixing cement mortar, cement will stick to the surface of the mixing shaft and mixing blades, so they need to be cleaned. Therefore, the mixing shaft and mixing blades in existing cement mortar mixers are mostly quick-release for easy cleaning. However, they need to be disassembled and cleaned separately after each use, which is a cumbersome process, wastes a lot of time, affects other work processes, and results in low work efficiency.

[0004] Therefore, it is necessary to invent a cement mortar mixer to solve the above problems. Utility Model Content

The rear end of the side baffles 16 is fixedly connected to the surface of the first equipment box 12, the third equipment box 3 and the water storage tank 4 respectively. The upper end of the side baffles 16 is fixedly connected to the second equipment box 2. Movable plates 17 are hinged to the front ends of the two sets of side baffles 16.

[0026] The lifting mechanism inside the first equipment box 12 and the stirring mechanism inside the second equipment box 2 are both existing technologies and will not be described in detail here. The front end of the support base 15 is an electromagnet. When the mixing pot is placed on its surface, it is energized to generate magnetism, which firmly attracts the mixing pot to its surface. During use, the two sets of movable plates 17 are opened, and the mixing pot containing the material is placed at the front end of the support base 15. Then, the support base 15 is energized to generate magnetism and fix the mixing pot. Then, the lifting mechanism inside the first equipment box 12 drives the upper side of the support base 15 to lift the mixing pot and place the stirring shaft 21 inside the mixing pot. At this time, the stirring mechanism inside the second equipment box 2 drives the stirring shaft 21 to rotate, stirring the material inside the mixing pot. At the same time, during the stirring process, sand is added into the mixing pot through the sand adding hole inside the second equipment box 2, and stirring continues to complete the preparation of cement mortar.

[0028] Specifically, during the cleaning process, the transmission assembly drives the two sealing shells 5 to slide and close together. After the two sets of sealing shells 5 are tightly fitted, the high-pressure pump inside the water storage tank 4 is started. The high-pressure pump sends water through the outlet into the inside of the water inlet hose 56. Then, the water inlet hose 56 sends water into the water guide pipe 51, and then it is divided into multiple diversion pipes 52. Then, the water is sprayed outward in a diffused manner through multiple sets of high-pressure nozzles 53 on the surface of the diversion pipes 52 to rinse the surface of the stirring shaft 21. At the same time, the wastewater generated during cleaning is discharged into the drain pipe 18 through the lower drain hose 54, and then discharged into the sludge collection box 11 for collection.

[0029] See Figure 3and Figure 4 The transmission assembly includes a bidirectional screw 31, a linear guide rail 32, an electric motor 33, a transmission rod 34, a linear bearing 35, and a transmission block 36. A positioning groove 37 is provided on the front surface of the third equipment box 3. Two sets of transmission rods 34 are slidably connected inside the positioning groove 37.

[0030] In addition, the mixer controller has a cleaning program. When the cleaning program is started, the output of the electric motor 33 drives the bidirectional screw 31 to rotate. During the rotation of the bidirectional screw 31, with the cooperation of two sets of linear bearings 35 and linear guide rails 32, the bidirectional screw 31 drives two sets of transmission rods 34 to slide and approach each other on its surface through two sets of transmission blocks 36, thereby driving the sealing shells 5 on both sides to slide and approach each other, and at the same time making the two sets of sealing shells 5 tightly connected, enclosing the mixing shaft 21 inside.
