Description

Technical Field

[0001] This utility model relates to the technical field of concrete processing, and in particular to a weighing device for high-toughness concrete. Background Technology

[0002] In the concrete production process, sand and gravel aggregates, cement, powder, and other additives need to be weighed and mixed according to the set gradation to prepare concrete for construction. To ensure the performance of the prepared concrete, precise measurement of various materials is required to guarantee the mix proportions. Currently, the commonly used weighing method is a wire-type weight sensor, where the hopper is connected to the bottom of the sensor for weighing. However, this method is only suitable for weighing small quantities of powder and admixtures; it is unsuitable for large quantities of sand and gravel aggregates. Therefore, a supported structure weighing sensor is typically used. Due to the large weighing capacity, a suitable support structure is required for fixing and installing the weighing sensor to ensure weighing accuracy and reliability.

[0003] Chinese Patent No. CN222013302U discloses a weighing scale fixing device, including a weighing scale. The outer wall of the weighing scale is provided with multiple sensor pressure seats, which correspond to the weighing sensors set on the upper end of the support. The outer wall of the weighing scale is also provided with multiple fixing seats. The support is provided with connecting nuts and connecting holes corresponding to the center of the connecting nuts. The support is provided with a raising unit, which includes a pad and a ring chain. The thickness of the pad is greater than the distance between the fixing seats and the support.

[0004] The existing technical solutions described above have the following drawbacks: Although the weighing scale fixing device achieves accurate weighing by setting multiple sensor pressure seats and weighing sensors, and the height can be adjusted by a shim unit to accommodate weighing scales of different heights, for materials like sand and gravel aggregates used in large quantities, due to their large weight and poor flowability, the aforementioned support structure is prone to deformation or damage after prolonged use, thus affecting the accuracy and reliability of weighing. Therefore, a more stable, reliable device suitable for weighing large quantities of materials such as sand and gravel aggregates in the production of high-toughness concrete is needed. Utility Model Content

[0005] The present invention aims to address the aforementioned shortcomings in the existing technology by providing a high-toughness concrete weighing device, which has the advantages of being suitable for weighing heavy materials, having good support stability, and reliable measurement.

[0006] The above-mentioned objective of this utility model is achieved through the following technical solution: A high-toughness concrete weighing device includes a support frame, a weighing hopper mounted on the support frame via multiple pairs of elastic expansion joints, a controller and multiple weighing sensors mounted on the support frame, a magnetic scale and a reading head respectively disposed at both ends of the elastic expansion joints and arranged in cooperation with each other, a sensor pressure seat disposed on the weighing hopper and pressed against the detection end of the weighing sensor, and a control valve disposed in the discharge section of the weighing hopper. The signal input terminal of the controller is electrically connected to the weighing sensor and the magnetic scale respectively, and the signal output terminal is electrically connected to the driver of the control valve.

[0007] By adopting the above technical solution, before feeding the vertical shaft planetary mixer, these weighing sensors transmit the weight signal of the material in the weighing hopper to the controller. The controller compares the weight signal with the weight threshold for reaching the predetermined discharge volume, calculates the travel distance of the reading head on the magnetic scale when the weight threshold is reached, and then sends the calculation result to the driver of the control valve to regulate the opening and closing of the control valve until the reading head travels to the corresponding position on the magnetic scale. The above structure not only realizes stable weighing of heavy materials such as sand and gravel aggregates, but also improves the accuracy and reliability of weighing through its unique structural design. At the same time, the support frame, as the supporting foundation of the entire equipment, has a robust and durable structural design that can withstand the weight of a large amount of material without deformation. Multiple pairs of elastic telescopic components are cleverly installed between the support frame and the weighing hopper. These elastic telescopic components can not only effectively buffer the impact force when the material falls, protecting the weighing hopper and support from damage, but also automatically adjust the telescopic length according to the weight of the material to ensure that the weighing hopper always remains horizontal, thereby further improving the weighing accuracy.

[0008] The present invention is further configured such that: the weighing hopper includes a gradually narrowing feeding section, a straight detection section, a gradually narrowing transition section and the discharge section arranged sequentially from top to bottom, and the elastic telescopic member and the sensor pressure seat are respectively disposed on the outer wall of the straight detection section.

[0009] By adopting the above technical solutions, the overall structure of the weighing hopper is made more reasonable, and the functions of different areas are clearly defined. The design of the tapered feeding section helps guide the material smoothly into the weighing hopper, avoiding material accumulation and blockage, and improving feeding efficiency. The flat detection section, as the core area of ​​weighing, provides stable support for the sensor with its flat surface, ensuring the accuracy of the weighing data. The tapered transition section plays a role in smooth transition, allowing the material to smoothly enter the discharge section from the flat detection section, avoiding material spillage and loss during the conversion process. At the same time, setting the elastic telescopic component and sensor pressure seat on the outer wall of the flat detection section not only facilitates installation and maintenance, but also effectively reduces the impact of the material on the sensor, further improving the stability and reliability of weighing.

[0010] The present invention is further configured such that the plurality of pairs of elastic telescopic members are evenly distributed along the circumference of the straight detection section.

[0011] By adopting the above technical solution, the elastic expansion member provides more uniform support to the straight detection section, avoiding weighing errors caused by uneven support and further improving the accuracy and stability of weighing.

[0012] The present invention is further configured such that: the elastic telescopic member includes two trays respectively disposed on the bracket and the weighing hopper, a linear bearing disposed between the two trays and a compression spring arranged in the linear bearing, and the magnetic scale and the reading head are respectively disposed on the two trays.

[0013] By adopting the above technical solution, the pallet provides a stable mounting base for the linear bearing and the compression spring. The linear bearing ensures smooth relative sliding between the pallets, reducing friction and resistance. The compression spring acts as a buffer and shock absorber, effectively absorbing the impact force generated when the material falls and protecting the weighing sensor from damage. At the same time, the magnetic scale and reading head can monitor the expansion and contraction of the elastic telescopic component in real time, thereby achieving precise control of the symmetrical weighing state of the hopper and further improving the weighing accuracy and stability.

[0014] The present invention is further configured such that the compression spring is a rectangular compression spring.

[0015] By adopting the above technical solution, the rectangular compression spring has a high comprehensive elastic coefficient, a large buffering and pressure degree, and can further buffer the impact of falling materials on the weighing sensor.

[0016] The present invention is further configured such that the plurality of weighing sensors are respectively arranged between two elastic telescopic members in each pair.

[0017] By adopting the above technical solution, the weighing sensor can accurately measure the force on each elastic expansion member, thereby calculating the weight of the material in the weighing hopper. Due to the setting of the elastic expansion member, the weighing sensor can be subjected to more uniform and stable pressure during measurement, avoiding measurement errors caused by uneven material distribution or excessive impact force. At the same time, the setting of multiple weighing sensors can also realize multi-point monitoring of the weight of the material in the symmetrical weighing hopper, further improving the accuracy and reliability of weighing.

[0018] The present invention is further configured such that at least two vibration motors are provided on the outer wall of the tapered transition section.

[0019] By adopting the above technical solution, the vibrating motor can generate high-frequency vibration, which effectively promotes the flow of materials in the weighing hopper, avoids blockage or accumulation of materials during the weighing process, ensures that materials can be smoothly discharged from the weighing hopper, and improves weighing efficiency and accuracy. At the same time, the design of the gradually narrowing transition section allows the materials to be gradually compressed during the discharge process, further improving the accuracy and stability of weighing.

[0020] The present invention is further configured such that the discharge section of the weighing hopper is installed at the feed end of the vertical shaft planetary mixer via a flexible connecting pipe.

[0021] By adopting the above technical solution, the design of the flexible connecting pipe not only ensures a stable connection between the weighing hopper and the vertical shaft planetary mixer, but also effectively isolates the influence of vibrations generated by the mixer on the symmetrical weighing hopper, thereby further improving the accuracy and stability of weighing.

[0022] In summary, the beneficial technical effects of this utility model are as follows: By combining the elastic telescopic component, the magnetic scale and the reading head, and the regulation of the control valve, this utility model not only achieves accurate weighing of heavy materials such as high-toughness concrete, but also ensures the stability and reliability of the weighing process. Furthermore, the equipment has a reasonable structural design, a sturdy and durable support that can withstand the weight of a large amount of material, and the elastic telescopic component effectively buffers the impact force when the material falls, protecting the weighing hopper and the support, and extending the service life of the equipment.

[0026] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Reference Figure 1This utility model discloses a high-toughness concrete weighing device, comprising a support 1, a controller 2 mounted on the support 1, a weighing hopper 3 mounted on the support 1 via four detection support components 4, and a control valve 5 disposed in the discharge section 34 of the weighing hopper 3. The signal input terminal of the controller 2 is electrically connected to the detection support components 4, and the signal output terminal is electrically connected to the driver of the control valve 5. The weighing hopper 3 includes a gradually narrowing feed section 31, a straight detection section 32, a gradually narrowing transition section 33, and a discharge section 34 arranged sequentially from top to bottom. The four detection support components 4 are evenly distributed circumferentially along the straight detection section 32. Two vibrating motors 6 are symmetrically arranged on the outer wall of the gradually narrowing transition section 33. The discharge section 34 of the weighing hopper 3 is used to be installed at the feed end of a vertical shaft planetary mixer via a flexible connecting pipe 7.

[0028] The design of the tapered feeding section 31 helps guide the material smoothly into the weighing hopper 3, avoiding material accumulation and blockage, and improving feeding efficiency. The flat detection section 32 serves as the core area for weighing, and its flat surface provides stable support for the sensor, ensuring the accuracy of the weighing data. The tapered transition section 33 plays a role in smooth transition, allowing the material to smoothly enter the discharge section 34 from the flat detection section 32, avoiding material spillage and loss during the transition process. At the same time, the elastic telescopic component 41 and the sensor pressure seat 45 are set on the outer wall of the flat detection section 32, which not only facilitates installation and maintenance, but also effectively reduces the impact of the material on the sensor, further improving the stability and reliability of weighing. The vibrating motor 6 generates high-frequency vibration, effectively promoting the flow of material within the weighing hopper 3. This prevents blockages or accumulation during weighing, ensuring smooth discharge from the hopper and improving weighing efficiency and accuracy. Simultaneously, the tapered transition section 33 allows for gradual compression of the material during discharge, further enhancing weighing precision and stability. The flexible connecting pipe 7 not only ensures a stable connection between the weighing hopper 3 and the vertical shaft planetary mixer but also effectively isolates the impact of vibrations generated by the mixer on the weighing hopper 3, further improving weighing accuracy and stability.

[0029] Reference Figure 2The detection support assembly 4 includes a pair of elastic telescopic members 41 disposed between the support 1 and the weighing hopper 3, a weighing sensor 42 disposed on the support 1 and arranged between the two elastic telescopic members 41, a magnetic scale 43 and a reading head 44 respectively disposed at both ends of the elastic telescopic members 41 and arranged in cooperation with each other, and a sensor pressure seat 45 disposed on the weighing hopper 3 and pressed against the detection end of the weighing sensor 42. The weighing sensor 42 can accurately measure the force on each elastic telescopic member 41, thereby calculating the weight of the material in the weighing hopper 3. Due to the setting of the elastic telescopic members 41, the weighing sensor 42 can be subjected to more uniform and stable pressure during measurement, avoiding measurement errors caused by uneven material distribution or excessive impact force. At the same time, the setting of these weighing sensors 42 can also realize multi-point monitoring of the weight of the material in the weighing hopper 3, further improving the accuracy and reliability of weighing.

[0030] The elastic telescopic component 41 includes two support plates 411 respectively disposed on the bracket 1 and the weighing hopper 3, a linear bearing 412 disposed between the two support plates 411, and a compression spring 413 arranged within the linear bearing 412. A magnetic scale 43 and a reading head 44 are respectively disposed on the two support plates 411, and the compression spring 413 is a rectangular compression spring. The support plates 411 provide a stable mounting base for the linear bearing 412 and the compression spring 413. The linear bearing 412 ensures smooth relative sliding between the support plates 411, reducing friction and resistance. The rectangular compression spring, with its high overall elastic coefficient and large buffering and pressure capacity, plays a role in buffering and shock absorption, effectively absorbing the impact force generated when the material falls, protecting the weighing sensor 42 from damage. Simultaneously, the magnetic scale 43 and the reading head 44 enable real-time monitoring of the telescopic component 41's expansion and contraction, thereby achieving precise control of the weighing state of the weighing hopper 3 and further improving the weighing accuracy and stability.

[0031] The implementation principle of this embodiment is as follows: Before the vertical shaft planetary mixer is fed, these weighing sensors 42 transmit the weight signal of the material in the weighing hopper 3 to the controller 2. The controller 2 compares the weight signal with the weight threshold of reaching the predetermined discharge amount, and calculates the travel distance of the reading head 44 on the magnetic scale 43 when the weight threshold is reached. The calculation result is then sent to the driver of the control valve 5 to regulate the opening and closing of the control valve 5 until the reading head 44 travels to the corresponding position of the magnetic scale 43. The above structure not only realizes the stable weighing of heavy materials such as sand and gravel aggregates, but also improves the weighing accuracy and reliability through its unique structural design. At the same time, the support 1, as the supporting foundation of the entire equipment, has a sturdy and durable structural design that can withstand the weight of a large amount of material without deformation. Multiple pairs of elastic telescopic parts 41 are cleverly installed between the support 1 and the weighing hopper 3. These elastic telescopic parts 41 can not only effectively buffer the impact force when the material falls, protecting the weighing hopper 3 and the support 1 from damage, but also automatically adjust the telescopic length according to the weight of the material to ensure that the weighing hopper 3 always remains horizontal, thereby further improving the weighing accuracy.
