Description

Technical Field

[0001] This utility model relates to the technical field of cement performance testing equipment, and in particular to a cement paste mixer. Background Technology

[0002] In the field of cement performance testing, cement paste mixers are the core equipment for preparing standard cement paste. Their operational stability and safety directly affect the accuracy of test data such as cement consistency and setting time, as well as the operational safety of operators.

[0003] Existing mixer protective covers are mainly of the manual opening and closing type and the electric independent control type. The manual type requires the operator to manually open and close the protective cover before and after the mixing pot is raised and lowered, which increases the operation steps and reduces efficiency; while the electric independent control type can open and close automatically, the electric type requires an additional drive and control module, which increases the manufacturing cost and maintenance difficulty. Therefore, a cement paste mixer is proposed to solve the above problems. Utility Model Content

[0004] (a) Purpose of the utility model To address the technical problems existing in the background art, this utility model proposes a cement paste mixer. By linking the protective cover with the machine frame through a transmission rod, the opening and closing of the protective cover and the lifting and lowering of the mixing pot are synchronized. This allows the opening and closing of the protective covers on both sides to be driven synchronously by the lifting and lowering of the mixing pot, reducing the number of operation steps and shortening the overall time for a single mixing.

[0005] (II) Technical Solution This utility model provides a cement paste mixer, including a base, a cement paste mixer body, a frame, a mounting base, a mixing shaft, and a mixing pot. The cement paste mixer body is vertically fixedly mounted on the upper surface of the base. The mixing shaft is vertically mounted on the drive end of the cement paste mixer body, and the lower end of the mixing shaft can extend into the interior of the mixing pot. The frame is horizontally positioned below the mixing shaft, and one end of the frame is connected to the lifting drive end of the cement paste mixer body. The frame is positioned away from the cement paste mixer body. The side end is connected to the mounting base. The mixing pot is detachably fixed to the upper surface of the mounting base. It also includes two protective covers and a transmission rod. The two protective covers are symmetrically distributed about the central axis of the mixing pot. The symmetrically arranged protective covers surround the outside of the mixing pot. When the two protective covers are closed, they can completely cover the side and top opening edge of the mixing pot. The bottom edge of the protective cover is hinged to the upper surface of the base through a hinge. The middle position of the inner side wall of the protective cover and the middle position of the side of the frame are movably connected through the transmission rod.

[0006] Furthermore, the overall shape of the two symmetrically distributed protective covers after splicing is compatible with the external contour of the cement paste mixer body, the horizontal extension direction of the frame, and the external dimensions of the mixing pot.

[0007] Furthermore, the mixing pot is made of stainless steel.

[0008] Furthermore, one end of the transmission rod is hinged to a pre-set connecting lug on the side of the frame via a pin, and the other end of the transmission rod is hinged to a pre-set connecting seat on the inner side wall of the protective cover via a pin.

[0009] Furthermore, the protective cover is made of polycarbonate transparent plastic material with a light transmittance of not less than 90%, and the wall thickness of the protective cover is 3-5mm.

[0010] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects: This cement paste mixer uses a transmission rod to link the protective cover with the frame, achieving synchronized opening and closing of the protective cover and raising and lowering of the mixing pot. When the mixing pot rises, the protective covers on both sides can cover the outside of the mixing pot, effectively preventing cement paste from splashing during the mixing process. When the mixing pot descends, the protective cover automatically closes. This allows the opening and closing of the protective covers on both sides to be synchronized with the raising and lowering of the mixing pot, reducing the number of operation steps and shortening the overall time for a single mixing cycle.

For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] like Figure 1-3 As shown, the present invention proposes a cement paste mixer, including a base 6, a cement paste mixer body 1, a frame 8, a mounting base 4, a mixing shaft 7, and a mixing pot 5. The cement paste mixer body 1 is vertically fixedly installed on the upper surface of the base 6. The mixing shaft 7 is vertically mounted on the drive end of the cement paste mixer body 1, and the lower end of the mixing shaft 7 can extend into the interior of the mixing pot 5. The frame 8 is horizontally arranged below the mixing shaft 7, and one end of the frame 8 is connected to the lifting drive end of the cement paste mixer body 1. The frame 8 is positioned away from the cement paste mixer body. One end of the body 1 is connected to the mounting base 4. The mixing pot 5 is detachably fixed to the upper surface of the mounting base 4. It also includes two protective covers 2 and a transmission rod 3. The two protective covers 2 are symmetrically distributed about the central axis of the mixing pot 5. The symmetrically arranged protective covers 2 surround the outside of the mixing pot 5. When the two protective covers 2 are closed, they can completely cover the side and top opening edge of the mixing pot 5. The bottom edge of the protective cover 2 is hinged to the upper surface of the base 6 through a hinge. The middle position of the inner side wall of the protective cover 2 and the middle position of the side of the frame 8 are movably connected through the transmission rod 3.

[0019] It should be noted that when the frame 8 moves up and down under the drive of the cement paste mixer body 1, the transmission rod 3 can smoothly convert the linear motion of the frame 8 into the rotational motion of the protective cover 2 around the hinge, ensuring that the opening and closing action of the protective cover 2 is coordinated and synchronized with the lifting action of the frame 8.

[0020] The cement paste mixer body 1 is a conventional core component of existing cement paste mixers. It integrates a power system (such as a motor, reducer, and transmission mechanism) to drive the mixing shaft 7, and a lifting drive system (such as a hydraulic cylinder, screw-slider mechanism, or pneumatic cylinder) to lift the frame 8. It is also equipped with corresponding control buttons to achieve basic functions such as mixing speed adjustment and lifting start / stop control. Since the specific structure, working principle, and control method of the cement paste mixer body 1 are all well-known technologies in the field and not the key improvements of this utility model, this application will not elaborate on them further, but will only clarify its installation position in this utility model and its connection relationship with other components.

[0021] In this embodiment, the overall shape of the two symmetrically distributed protective covers 2 after splicing is compatible with the outer contour of the cement paste mixer body 1, the horizontal extension direction of the frame 8, and the outer dimensions of the mixing pot 5.

[0022] It should be noted that this ensures that the protective cover 2 will not interfere with other components during the opening and closing process, thus guaranteeing the overall stability of the equipment operation.

[0023] In this embodiment, the mixing pot 5 is made of stainless steel.

[0024] It should be noted that the mixing pot 5 is used to hold the cement paste material to be mixed, and the stainless steel material has good corrosion resistance and wear resistance, which can prevent cement paste from adhering and is easy to clean, thus extending the service life of the mixing pot 5.

[0025] In this embodiment, one end of the transmission rod 3 is hinged to the side connecting ear plate of the frame 8 via a pin, and the other end of the transmission rod 3 is hinged to the connecting seat on the inner side wall of the protective cover 2 via a pin.

[0026] It should be noted that, through the transmission action of the transmission rod 3, the lifting motion of the frame 8 can be converted into the opening and closing motion of the protective cover 2.

[0027] In this embodiment, the protective cover 2 is made of polycarbonate transparent plastic material with a light transmittance of not less than 90%, and the wall thickness of the protective cover 2 is 3-5mm.

[0028] It should be noted that the high light transmittance material allows operators to observe the mixing status of the cement paste in the mixing pot in real time. The 3-5mm wall thickness ensures that the protective cover 2 has sufficient strength to resist the impact of splashing cement paste, while also preventing the protective cover 2 from being too heavy and affecting the flexibility of opening and closing.

[0029] Working principle: When using the equipment, first add cement and water to the mixing pot 5, then install the mixing pot 5 on the mounting base 4. The operator then activates the lifting drive function via the control button on the cement paste mixer body 1. The machine body drives the frame 8 to move vertically upwards (at this point, the mixing pot 5 rises to a position with sufficient operating space at the lower end of the mixing shaft 7). Since the frame 8 is connected to the protective cover 2 via the transmission rod 3, the upward movement of the frame 8 generates an upward pulling force on the transmission rod 3. The transmission rod 3, using the pin connected to the frame 8 as a fulcrum, drives the protective cover 2 to rotate, causing the two protective covers 2 to close and cover the mixing pot 5. At this time, the operator... The operator starts the mixing drive function, and the mixing shaft 7 performs planetary motion mixing of the material. The protective cover 2 can effectively prevent cement paste from splashing, and the operator can observe the mixing status through the transparent protective cover 2. After the mixing operation is completed, the operator first stops the rotation of the mixing shaft 7, and then controls the machine body to drive the frame 8 to move downward. The mixing pot 5 descends with the frame 8. During this process, the transmission rod 3 pushes the protective cover 2 to flip outward and open. When the frame 8 descends to the preset height of the initial preparation stage, the protective cover 2 is fully opened. The operator can then remove the mixing pot 5 from the mounting base 4 to pour out the cement paste and clean the mixing pot 5, thus completing a complete mixing process.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
