Description

Technical Field

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

[0002] Cement mortar is a commonly used material in construction engineering. It is usually made by mixing cement, standard sand and water in a specific ratio. It is mainly used to test the mechanical properties of cement (such as compressive and flexural strength), and can also be used in construction scenarios such as masonry and plastering.

[0003] Chinese utility model patent CN217476263U, published on September 23, 2022, discloses a cement mortar mixer, including a frame, controller, lifting device, mixing pot, mixing device, sand adding device, and dust cover device. The controller is mounted on the frame. The lifting device includes a bracket, an electromagnet, and a first drive mechanism. The bracket is vertically movable on the frame, the electromagnet is mounted on the bracket and connected to the controller, and the first drive mechanism is mounted on the frame and drives the bracket to move vertically. The mixing device is mounted on the frame and located above the mixing pot, and is connected to the controller. The sand adding device allows for automatic sand adding at a uniform rate, preventing sand accumulation in the hopper and ensuring accurate sand addition. The dust cover device effectively prevents dust generation during the mixing process by covering the lifting device, mixing pot, mixing device, and sand adding device.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the existing mixing devices do not have a sealing structure for the opening of the mixing container, which may cause cement mortar to spill out during high-speed mixing, thereby limiting the maximum mixing speed and preventing further improvement in efficiency. In addition, the vertical container makes it inconvenient to pour cement mortar. Utility Model Content

[0005] The purpose of this invention is to solve the technical problems of existing mixing devices, which lack a sealing structure for the opening of the mixing container, causing cement mortar to spill out during high-speed mixing, thus limiting the maximum mixing speed and preventing further efficiency improvement. In addition, the vertical container makes it inconvenient to pour cement mortar. The invention provides a cement mortar mixing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention relates to a cement mortar mixing device, comprising a support frame; a motor fixedly connected to the support frame; a stepped shaft fixedly connected to the output shaft of the motor; a transmission plate fixedly connected to the stepped shaft; a mixing container inserted into a slot on the transmission plate; a mixing plate inserted into the mixing container; a mixing shaft fixedly connected to the mixing plate; a drive unit provided on the mixing shaft; limit plates fixedly connected at intervals on the mixing shaft; and multiple symmetrically connected symmetrical cover plates inserted into the limit plates.

[0008] Furthermore, a synchronization plate is movably sleeved on the upper end of the stirring shaft; a motor is fixedly connected to the synchronization plate; a second gear is fixedly connected to the output shaft of the motor; a first gear is meshed and driven on the second gear; the first gear is fixedly connected to the stirring shaft; and a hydraulic rod is fixedly connected between the synchronization plate and the support frame.

[0009] Furthermore, a protruding plate is detachably fixed to one side of the support frame; multiple optical axes are rotatably inserted between the protruding plate and the support frame.

[0010] The cement mortar mixing device provided by this utility model has the following beneficial effects:

[0011] 1. This utility model involves placing the cement mortar raw material to be mixed into a mixing container, then driving the mixing shaft to descend along with the mixing plate and symmetrical cover plate. The symmetrical cover plate closes the mixing container, and the mixing plate descends into the mixing container. The driving unit then drives the mixing shaft and mixing plate to rotate at high speed to mix the cement mortar. This high-speed mixing prevents the cement mortar from splashing out of the mixing container. After mixing is complete, the driving unit drives the mixing plate to rise and detach from the mixing container. The motor drives the stepped shaft, transmission plate, and mixing container to rotate and tilt slowly, thus tilting the mixed cement mortar out. This reduces the height from which the cement mortar is poured out, resulting in higher pouring efficiency and greater convenience.

[0012] 2. This utility model utilizes the telescopic movement of a hydraulic rod, which in turn moves a synchronous plate up and down, thereby causing the stirring shaft and stirring plate to move up and down. This allows for easy and quick removal of the mixed cement mortar from the mixing container. A motor drives a second gear to rotate, which in turn rotates the first gear, stirring shaft, and stirring plate, mixing the cement mortar within the container. As the stirring shaft and stirring plate descend, symmetrical cover plates descend synchronously to cover the upper opening of the mixing container. Since the symmetrical cover plates are rotatably fitted onto the stirring shaft, they do not rotate with it, thus stably sealing the upper opening of the mixing container. This allows for a higher rotation speed of the stirring plate without splashing cement mortar during high-speed mixing. After mixing, the stirring plate rises and detaches from the mixing container. The motor then slowly rotates and tilts the stepped shaft, transmission plate, and mixing container, tilting the mixed cement mortar out. This reduces the pouring height, resulting in higher efficiency and greater convenience. Attached Figure Description

Detailed Implementation

[0019] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0022] Please see Figure 1-4 As shown, a cement mortar mixing device includes a support frame 1; a motor 2 is fixedly connected to the support frame 1; a stepped shaft 3 is fixedly connected to the output shaft of the motor 2; a transmission plate 4 is fixedly connected to the stepped shaft 3; a mixing container 5 is inserted into a slot on the transmission plate 4; a mixing plate 8 is inserted into the mixing container 5; a mixing shaft 9 is fixedly connected to the mixing plate 8; a drive unit is provided on the mixing shaft 9; limit plates 10 are fixedly connected at intervals on the mixing shaft 9; a plurality of symmetrically connected symmetrical cover plates 11 are inserted into the limit plates 10; by placing the cement mortar raw material to be mixed into the mixing container 5, the drive unit drives the mixing shaft 9 to descend, carrying the mixing plate 8. The symmetrical cover plate 11 descends, sealing the mixing container 5. The mixing plate 8 descends into the mixing container 5. Then, the drive unit drives the mixing shaft 9 and the mixing plate 8 to rotate at high speed to mix the cement mortar. This high-speed mixing prevents the cement mortar from splashing out of the mixing container 5. After mixing is complete, the drive unit drives the mixing plate 8 to rise and detach from the mixing container 5. The motor 2, along with the stepped shaft 3, transmission plate 4, and mixing container 5, slowly rotates and tilts, thus tilting the mixed cement mortar out. This reduces the height from which the cement mortar is poured out, making the pouring more efficient and convenient.

[0023] A synchronizing plate 12 is movably sleeved on the upper end of the stirring shaft 9; a motor 15 is fixedly connected to the synchronizing plate 12; a second gear 14 is fixedly connected to the output shaft of the motor 15; a first gear 13 is meshed and driven on the second gear 14; the first gear 13 is fixedly connected to the stirring shaft 9; a hydraulic rod 16 is fixedly connected between the synchronizing plate 12 and the support frame 1. When the hydraulic rod 16 is energized, it extends and retracts, pushing and pulling the synchronizing plate 12 up and down, thereby causing the stirring shaft 9 and the stirring plate 8 to move up and down, allowing them to move up and down from inside the mixing container 5. This allows for convenient and quick removal of the mixed cement mortar when needed. The second gear 14 is rotated by the energized motor 15, which in turn rotates the first gear 13, the stirring shaft 9, and the stirring plate 8, thus mixing the contents of the mixing container 5. Cement mortar is mixed, and then, as the mixing shaft 9 and mixing plate 8 descend, the symmetrical cover plate 11 descends synchronously to cover the upper opening of the mixing container 5. At the same time, since the symmetrical cover plate 11 is rotatably sleeved on the mixing shaft 9, it will not rotate with the rotation of the mixing shaft 9, thus stably sealing the upper opening of the mixing container 5. This allows the rotation speed of the mixing plate 8 to be further increased without splashing cement mortar during high-speed mixing. After mixing is completed, the mixing plate 8 rises and detaches from the mixing container 5. Then, the motor 2 slowly rotates and tilts the stepped shaft 3, transmission plate 4, and mixing container 5, thereby tilting and pouring out the mixed cement mortar. This reduces the height of the poured cement mortar, making the pouring more efficient and convenient.

[0024] A protruding plate 17 is detachably fixed to one side of the support frame 1; multiple optical shafts 18 are rotatably inserted between the protruding plate 17 and the support frame 1. Through the multiple freely rotating optical shafts 18, when the container is easily placed on the optical shafts 18, it can be moved with low resistance, making it more convenient and labor-saving to unload the cement mortar.

[0025] The mixing plate 8 has a through groove, which keeps the rotational resistance of the mixing plate 8 at a low level, allowing it to rotate at high speed to mix cement mortar.

[0026] The transmission plate 4 has a corresponding hole for the stirring container 5 with a threaded connection to a fastener 6. The fastener 6 allows the stirring container 5 to be more stably installed and fixed in the groove on the transmission plate 4, and different stirring containers 5 can be replaced to achieve continuous stirring operation on multiple test samples.

[0027] The upper surface of the stepped shaft 3 is provided with a storage groove 7. The storage groove 7 reduces the weight of the stepped shaft 3 and the torque loss of the motor 2, while also allowing a small number of tools that need to be fixed to be placed to be placed, making the cement mortar mixing operation more convenient.
