Description

Technical Field

[0001] This utility model relates to the field of building material flow performance testing technology, specifically a building material flow measuring instrument. Background Technology

[0002] The field of building material flow performance testing technology mainly involves the determination and analysis of the flowability of various building materials under different environmental conditions. These tests are typically used to evaluate the workability, maneuverability, and stability of materials during construction, ensuring that the materials meet required flowability standards in practical applications. The flowability of building materials is a crucial factor affecting the construction effect, strength, and durability of materials such as concrete, mortar, and asphalt. Therefore, flow performance testing plays a vital role in improving the quality of construction projects and ensuring construction safety. Flowability testing techniques include various methods, such as slurry flowability, slurry viscosity, and slump. These tests can effectively evaluate the performance of building materials during construction. A building material flow meter is a device specifically designed to measure the flowability of building materials. It typically quantitatively measures the flow of samples to help engineers understand the flow characteristics of materials. This equipment is widely used in the production and quality control of building materials such as concrete and mortar, ensuring that these materials maintain good flowability and maneuverability during construction, thereby improving construction efficiency and material performance.

[0003] Existing technologies have significant limitations in operation. Traditional equipment relies on gravity to drive material flow and lacks an effective flow rate control mechanism, resulting in significant differences in the discharge rate of materials with different viscosities or particle sizes, affecting the comparability of test results. Limit controls often employ fixed or simple manual structures, which cannot maintain a stable state during continuous testing and are prone to sudden material outflow or blockage, introducing data fluctuations. The equipment lacks adaptability and cannot automatically adjust parameters according to material conditions, requiring frequent operator intervention and correction, which not only increases workload but also reduces testing efficiency.

[0017] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0018] Please see Figure 1-5 In this embodiment: a building material flow measuring instrument includes a cylinder 1, a discharge pipe 2 fixedly connected inside the cylinder 1, a connecting block 3 fixedly connected to the outer wall of the discharge pipe 2, a rotating hole 4 opened inside the connecting block 3, a first rotating shaft 5 rotatably connected to the inner wall of the rotating hole 4, a fixing plate 6 fixedly connected to the outer wall of the first rotating shaft 5, a baffle 7 fixedly connected to one side of the fixing plate 6, a connecting plate 8 fixedly connected to one side of the baffle 7, a spring 9 fixedly connected to the outer surface of the connecting plate 8, a hook 10 fixedly connected to one end of the spring 9, a hanging rod 11 fixedly connected to the outer wall of the discharge pipe 2, and the hook 10 slidably connected to the outer wall of the hanging rod 11.

[0019] In this embodiment, by integrating a rotatable shaft and connecting a limiting structure on the outer wall of the discharge channel, the rotation of the shaft drives the baffle 7 to move. Combined with the tension of the spring 9 and the sliding engagement of the hook 10 on the hanging rod 11, the opening and closing amplitude of the discharge port can be dynamically adjusted. The extension and retraction of the spring 9 and the movement of the baffle 7 are coordinated to maintain a uniform rhythm in the material discharge process, avoiding test errors caused by sudden changes in flow rate. The sliding connection between the hook 10 and the hanging rod 11 provides adaptive space, which can automatically adjust the tension according to the material characteristics, ensuring the stability and repeatability of flow control under different material conditions.

[0020] Preferably, a sleeve 12 is slidably connected to the outer wall of the cylinder 1, and a limiting groove 13 is formed on the inner wall of the sleeve 12. A limiting block 14 is slidably connected to the inner wall of the limiting groove 13, and the limiting block 14 is fixedly connected to the outer wall of the cylinder 1.

[0021] The device height is adjusted by integrating a sliding sleeve 12 and a limiting structure on the outer wall of the cylinder 1, and by moving the sleeve 12 up and down.

[0022] Preferably, a bracket 15 is fixedly connected to the lower surface of the sleeve 12, and a base plate 16 is fixedly connected to the lower surface of the bracket 15.

[0023] The bracket 15 and the base plate 16 together form a stable support foundation to ensure the stability of the equipment position during the testing process.

[0024] Furthermore, a timer 18 is fixedly connected to the outer wall of the sleeve 12, and a sensor 17 is fixedly connected to one side of the connecting plate 8. The sensor 17 is electrically connected to the connecting plate 8.

[0025] The timer 18 works in conjunction with the sensor 17 to automatically capture the start and end times of the flow, enabling accurate recording of time parameters and reducing human error.

[0026] Furthermore, a mounting bracket 19 is fixedly connected to one side of the upper surface of the base plate 16, a motor 20 is fixedly connected to the upper surface of the mounting bracket 19, a second rotating shaft 21 is fixedly connected to the output end of the motor 20, an eccentric wheel 22 is fixedly connected to the upper surface of the second rotating shaft 21, and the eccentric wheel 22 is in contact with the outer wall of the cylinder 1.

[0027] Among them, the motor 20 drives the rotating shaft to rotate the eccentric wheel 22, generating controllable vibration that acts on the cylinder 1, promoting uniform material flow and avoiding particle deposition or flow stagnation caused by static placement.

[0028] Preferably, a level 23 is fixedly connected to one side of the upper surface of the base plate 16.

[0029] Among them, the level 23 monitors the placement status of the equipment in real time to ensure that the test platform is always in a horizontal position and eliminates the influence of tilt on the flow direction.

[0030] Furthermore, a fixing bracket 24 is fixedly connected to the lower surface of the base plate 16, and a screw 25 is threadedly connected to the inside of the fixing bracket 24. An anti-slip pad 26 is fixedly connected to the lower surface of the screw 25.

[0031] The fixed frame 24 and the screw 25 adjust the support height by screwing in the thread, and the anti-slip pad 26 enhances the friction of the bottom surface, further strengthening the adaptability of the equipment to various ground conditions.

[0032] The working principle and usage process of this utility model are as follows: The initial height of the cylinder 1 containing building materials can be flexibly adjusted through the cooperation of the sliding sleeve 12 and the limiting block 14 to adapt to different testing standards or container requirements. The supporting base plate 16 and the built-in level 23 together ensure that the entire device is in a precise horizontal state, while the screw 25 at the bottom and the anti-slip pad 26 further lock the device, eliminating errors caused by instability or tilting of the device during testing. The motor 20 drives the rotating shaft, causing the eccentric wheel 22 to rotate at a uniform speed. The eccentric wheel 22 periodically contacts and acts on the outer wall of the cylinder 1, transmitting controllable and uniform mechanical vibration to the building materials inside the cylinder. This vibration effectively overcomes the static friction and cohesion between particles inside the material, simulating the mixing or vibration conditions during construction, prompting the material to start and maintain a more realistic and uniform flow state. When the baffle 7 is operated to open the discharge port, the connecting plate 8 rigidly connected to it will move synchronously, thereby triggering the sensor 17 on it. Sensor 17 immediately sends an electrical signal to timer 18, which then begins to accurately record the time. Building materials flow out under vibration excitation. When the flow stops or reaches a preset endpoint, the operator can manually stop the timer, or another sensor can trigger a stop signal, thus automatically acquiring the entire flow time.

[0033] The operating procedure is as follows: Place the equipment on a solid, flat workbench. Gently press down on the base plate 16 and observe the bubble in the built-in level 23. Slowly rotate the multiple screws 25 in the fixing bracket 24 below the base plate 16, adjusting their height until the bubble is stably centered. At this point, the equipment is completely leveled. The anti-slip pad 26 effectively prevents the equipment from shifting during subsequent vibrations. According to the test specifications, slide the sleeve 12 up or down. Through the engagement of its internal limiting groove 13 with the limiting block 14 on the outer wall of the cylinder 1, adjust the cylinder 1 to the preset initial height. Evenly fill the cylinder 1 with the pre-mixed building material to be tested (such as concrete or mortar), and smooth the upper surface with a trowel to ensure there are no large air bubbles inside. Ensure that the timer 18 has been reset to zero. The operator is in position, ready to open the baffle 7, and start the motor 20 to make the eccentric wheel 22 start rotating, generating stable vibrations on the cylinder 1. Almost simultaneously, quickly rotate the shaft to remove the baffle 7 from the discharge port. The movement of baffle 7 immediately triggers sensor 17 via connecting plate 8, and timer 18 automatically starts timing. Under continuous vibration, building materials flow out of the outlet evenly and smoothly and diffuse outwards. Operators must observe the material flow pattern. When the material flow front stops diffusing, or reaches the standard specified diffusion diameter, timer 18 is manually stopped. The time displayed on timer 18 at this time is the specific flow time of the material under vibration conditions. Record the flow time and simultaneously measure parameters such as the final diameter of the material after spreading. Turn off motor 20, vibration stops, and clean residual material from cylinder 1, discharge pipe 2, and bottom plate 16 to prepare for the next test. Reset timer 18, and all moving parts return to their initial state.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
