Description
Technical Field
[0001] The present application relates to the technical field of concrete performance testing, and specifically to a cement mortar mixing device. Background Art
[0002] The preparation and mixing of cement mortar is crucial in testing concrete performance. Cement mortar is a mixture of cement, fine aggregate, and water (i.e., cement + sand + water), and is prepared as needed. Cement mixed mortar is made from cement, fine aggregate, lime, and water. The two are different concepts, with different names and uses. Cement mortar is the main component of concrete.
[0003] During the concrete testing process, cement mortar needs to be stirred. The stirring method and structure of traditional stirring devices often cannot achieve the ideal effect, resulting in uneven mixing of cement mortar, low stirring efficiency, inconvenient operation, and the stirring structure is not easy to disassemble and clean. The stirring device cannot be adjusted according to specific mixing needs, and its adaptability is low. Utility Model Content
[0004] In response to the shortcomings of the existing technology, the present application provides a cement mortar mixing device, which has the advantages of improving the uniformity and mixing efficiency of cement mortar mixing, and is easy to operate and use, conveniently disassemble and clean the mixing structure, and conveniently adjust the mixing depth as needed. It solves the problem that the stirring method and structure of traditional stirring devices often fail to achieve the ideal effect, resulting in uneven mixing of cement mortar, low mixing efficiency, inconvenient operation, and the stirring structure is not easy to disassemble and clean. The stirring device cannot be adjusted according to specific mixing needs, and has low adaptability.
[0005] To achieve the above-mentioned purpose, the present application provides the following technical solution: a cement mortar mixing device, comprising a main body, an outer shell fixedly connected to the interior of the main body, an upper surface of the outer shell provided with a motor, the bottom surface of the motor being rotatably connected to a base plate via an output shaft, the bottom surface of the base plate being fixedly connected to a fixing rod, two rotating rods being rotatably plugged into the interior of the base plate, the bottom surfaces of the fixing rod and the rotating rod being fixedly connected to a mounting seat, and an agitator being slidably plugged into the interior of each mounting seat.
[0006] Through the above scheme, since the stirring method and structure of the traditional stirring device often cannot achieve the ideal effect, the cement mortar is not stirred evenly, the stirring efficiency is relatively low, and the operation is not convenient enough. The stirring structure is not easy to disassemble and clean, and the stirring device cannot be adjusted according to specific stirring needs. The adaptability is low. The bottom plate drives the gear and the inner ring to engage during the rotation, so that the agitators on both sides can rotate while rotating with the rotation of the bottom plate, thereby improving the stirring efficiency and uniformity of the cement mortar. The positioning rod is driven by the control rod to be retracted and extended during the rotation, so that the agitator can be flexibly disassembled, which is convenient for disassembly and cleaning of the agitator. By setting an electric lifting rod, the base can drive the container to rise and fall, and the stirring depth of the container can be adjusted according to needs.
[0007] Furthermore, a first limiting ring is fixedly sleeved on the outer circumferential surface of each rotating rod, and the outer circumferential surface of the first limiting ring is rotatably connected to the interior of the bottom plate.
[0008] Through the above solution, the rotating rod is restricted to prevent the rotating rod from sliding longitudinally, thereby increasing the stability of the rotating rod movement.
[0009] Furthermore, a gear is fixedly sleeved on the outer circumferential surface of each rotating rod, an inner gear ring is fixedly connected to the inner wall of the outer shell, and the gear and the inner gear ring are meshed.
[0010] Through the above solution, the bottom plate drives the gear and the inner gear ring to engage during rotation, so that the agitators on both sides can rotate while following the rotation of the bottom plate, thereby improving the mixing efficiency and uniformity of the cement mortar.
[0011] Furthermore, a control rod is rotatably inserted into the interior of each mounting seat, and a positioning rod is threadedly connected to the outer circumference of the control rod. The outer circumference of the positioning rod is slidably inserted into the agitator through an empty groove opened inside the agitator.
[0012] According to the above solution, the positioning rod is driven to be retracted and extended during the rotation of the control rod, so that the agitator can be flexibly disassembled, and the agitator can be easily disassembled and cleaned.
[0013] Furthermore, a second limiting ring is fixedly sleeved on the outer circumferential surface of the control rod, and the outer circumferential surface of the second limiting ring is rotatably connected to the interior of the mounting seat.
[0014] Through the above solution, the control rod is restricted, the sliding and deviation of the control rod are avoided, and the stability of the control rod movement is increased.
[0015] Furthermore, two limiting plates are fixedly connected to the outer circumferential surface of the positioning rod, and the outer surface of each limiting plate is slidably connected to the mounting seat through a hollow groove provided inside the mounting seat.
[0016] Through the above solution, the positioning rod is restricted to prevent the positioning rod from rotating along with the control rod, so that the positioning rod is always moved and retracted laterally.
[0017] Furthermore, an electric lifting rod is provided inside the main body, the bottom end of the electric lifting rod is fixedly connected to a base, and a container is provided above the base.
[0018] Through the above solution, the height of the container can be adjusted by the electric lifting rod and the base, which makes it convenient to take and place the container, and also makes it convenient to adjust the stirring depth in the container as needed.
[0019] Furthermore, the bottom surface of the container is fixedly connected with equally spaced limiting rods, and the outer circumferential surface of each limiting rod is slidably connected to the base through a hollow groove provided inside the base.
[0020] Through the above solution, the container is restricted and the stability of the container during the stirring operation is increased.
[0021] Compared with the existing technology, the technical solution of this application has the following beneficial effects:
[0022] The cement mortar mixing device drives the gear and the inner gear ring to engage during the rotation of the base plate, so that the agitators on both sides can rotate while following the rotation of the base plate. The positioning rod is driven to be retracted and extended by the control rod during the rotation, so that the agitator can be flexibly disassembled. By providing an electric lifting rod, the base can drive the container to be raised and lowered, thereby achieving the effect of improving the mixing efficiency and uniformity of the cement mortar, facilitating the disassembly and cleaning of the agitator, and being able to adjust the mixing depth of the container, thereby solving the problems of uneven mixing of cement mortar, low mixing efficiency, low convenience and adaptability of traditional mixing devices.

[0033] See also Figure 4 The outer circumference of each rotating rod 6 is fixedly sleeved with a first limiting ring 9, and the outer circumference of the first limiting ring 9 is connected to the internal rotation of the bottom plate 4 to limit the rotating rod 6, prevent the rotating rod 6 from sliding longitudinally, and increase the stability of the movement of the rotating rod 6.
[0034] See also Figure 3 and Figure 4 The outer circumference of each rotating rod 6 is fixedly sleeved with a gear 10, and the inner wall of the outer shell 2 is fixedly connected with an inner gear ring 11. The gear 10 and the inner gear ring 11 are meshed with each other, and the bottom plate 4 drives the gear 10 and the inner gear ring 11 to mesh during the rotation process, so that the agitators 8 on both sides can rotate while following the rotation of the bottom plate 4, thereby improving the mixing efficiency and uniformity of the cement mortar.
[0035] See also Figure 3 、 Figure 4 and Figure 6A control rod 12 is rotatably inserted into the interior of each mounting seat 7, and a positioning rod 13 is threadedly connected to the outer circumference of the control rod 12. The outer circumference of the positioning rod 13 is slidably inserted into the agitator 8 through the empty groove opened inside the agitator 8. The positioning rod 13 is driven to be retracted and extended during the rotation of the control rod 12, so that the agitator 8 can be flexibly disassembled, which is convenient for disassembly and cleaning of the agitator 8.

[0041] It should be noted that a hand wheel is provided on the outer circumference of the control rod 12 , and anti-slip grooves arranged at equal intervals are provided on the outer circumference of the hand wheel to facilitate the manipulation of the control rod 12 by the hand wheel.
[0042] The working principle of the above embodiment is:
[0043] When the performance of concrete needs to be tested, cement mortar can be loaded into the container 18, and then the container 18 is installed on the base 17 through the limit rod 19. Then, the motor 3 is started as power to drive the bottom plate 4 to rotate through the output shaft. The bottom plate 4 drives the middle agitator 8 to rotate through the fixed rod 5 and the middle mounting seat 7. At the same time, the bottom plate 4 drives the mounting seats 7 and the agitator 8 on both sides to rotate through the rotating rod 6. The rotating rod 6 drives the gear 10 to mesh with the inner gear ring 11 as the bottom plate 4 rotates, prompting the agitators 8 on both sides to rotate, so as to evenly mix the cement mortar in the container 18 and improve the mixing efficiency. The height of the base 17 and the container 18 can be adjusted by the electric lifting rod 16, which is convenient for taking and placing the container 18, and also convenient for adjusting the mixing depth of the cement mortar as needed. The rotatable control rod 12 drives the positioning rod 13 to move out from the inside of the agitator 8, canceling the positioning restriction of the agitator 8, and facilitating the disassembly and cleaning of the agitator 8.
