Description

Technical Field

[0001] The utility model relates to the technical field of cement mixing, and more specifically to a cement mixer. Background Art

[0002] Cement paste refers to a mixture of cement and water with certain plastic properties. An artificial stone formed by cement hydration and hardening is called cement stone, or hardened cement paste, sometimes referred to as cement paste.

[0003] Announcement No. CN216732419U proposes a new type of cement slurry mixer. However, the existing cement slurry mixer is mainly used to manually add mixing water into the mixing barrel during use. At the same time, the mixing barrel and the mixing frame are also mainly cleaned manually after use, which makes the water adding and cleaning process of the mixer relatively cumbersome. Through the design of the water tank, water pump, water pipe, water storage tray and nozzle, on the one hand, the automatic water adding operation of the mixer can be realized, and on the other hand, by spraying water on the mixing barrel and the mixing frame after the mixer is used, the automatic cleaning operation of the mixer can be realized, which greatly improves the use efficiency of the mixer.

[0004] However, in the above device, the main components for stirring the cement slurry are the stirring shaft and the stirring frame. First, the stirring frame, as shown in the attached figure, has a horizontal stirring function. The cement at the bottom and the top cannot be exchanged during stirring, resulting in insufficient contact between the cement and water and poor stirring efficiency. Utility Model Content

[0005] In order to overcome the above defects of the prior art, the utility model provides a cement mixer to solve the problems existing in the above background technology.

[0006] The utility model provides the following technical solutions: a cement mixer, comprising a base, an L-shaped seat with adjustable height is installed on the upper surface of the base, a driving motor is fixedly connected to the upper surface of the L-shaped seat, an output end of the driving motor extends to the lower surface of the L-shaped seat and is fixedly connected to a rotating disk, a gear is rotatably connected to the lower surface of the rotating disk, a rotating rod is detachably installed on the lower surface of the gear, a spiral stirring blade is fixedly connected to the surface of the rotating rod, a mounting ring is fixedly connected to the lower surface of the L-shaped seat, an inner ring surface of the mounting ring is fixedly connected to an inner gear ring meshing with the gear surface, a supporting seat is fixedly connected to the upper surface of the base, and a mixing kettle is fixedly connected to the upper surface of the supporting seat, and a discharge gate is installed on the surface of the mixing kettle;

[0007] The upper surface of the base is fixedly connected to a concave box, the surface of the L-shaped seat overlaps the inner wall of the concave box, and the side of the concave box is fixedly connected to two fixed plates, the opposite surfaces of the two fixed plates are rotatably connected to a driving screw driven by a motor, the surface of the driving screw is threadedly connected to a concave connecting plate, the side of the concave connecting plate is fixedly connected to the side of the L-shaped seat, and the side of the concave connecting plate overlaps the side of the concave box.

[0008] A further solution is that there are several gears, and the several gears are arranged in a circular array on the lower surface of the rotating disk. The lower surface of the gear is fixedly connected with a mounting sleeve, and the top of the rotating rod is fixedly connected with a connecting block, and the surface of the connecting block overlaps with the inner wall of the mounting sleeve. T-slots are provided on both sides of the connecting block, and a T-shaped plug-in block is slidably connected to the inner wall of the T-slot. The upper surface of the T-shaped plug-in block is fully arc-shaped, and the lower surface of the T-shaped plug-in block is semi-arc-shaped. A spring is fixedly connected to the opposite surface of the T-shaped plug-in block and the T-slot, and a positioning opening matched with the T-shaped plug-in block is provided on the inner wall of the mounting sleeve, and the surface of the T-shaped plug-in block overlaps with the inner wall of the positioning opening.

[0009] Technical effects and advantages of the utility model:

[0010] 1. The cement mixer starts the drive motor, which can drive the rotating disk to rotate, and then drive the rotating rod to rotate to stir the mud. While the rotating disk rotates, the gear is engaged with the inner gear ring. The rotation of the gear causes the rotating rod to drive the spiral stirring blade to rotate, turning the mud up and down, so that the mixer can perform multi-level mixing of cement to ensure the mixing effect.

[0011] 2. The cement mixer can drive the concave connecting plate to move by driving the screw rod to rotate through the motor, thereby driving the L-shaped seat to move in the concave box to lift the spiral stirring blade, press the T-shaped plug block, so that the arc surface of the lower surface of the T-shaped plug block is located at the positioning port, and the rotating rod is pulled out. The arc surface of the T-shaped plug block is forced to be accommodated in the T-shaped groove, which is convenient for disassembly of the rotating rod. The connecting block is inserted into the installation sleeve, and the upper arc surface of the T-shaped plug block is forced to be accommodated in the T-shaped groove. After the connecting block is completely placed, the elastic force of the spring pushes the T-shaped plug block to be inserted into the positioning port to fix the position of the rotating rod, thereby facilitating the disassembly and assembly of the rotating rod and facilitating cleaning.
