Description

Technical Field

[0001] The utility model belongs to the technical field of mixers, and in particular relates to a weighing device for a mixer. Background Art

[0002] Concrete refers to an artificial stone made of cement as the main cementitious material, water, sand, gravel, and chemical admixtures and mineral admixtures when necessary, which are mixed in appropriate proportions and are uniformly stirred, compacted, formed, and cured and hardened. When concrete is used, a variety of admixtures are generally added to improve the strength of the concrete. In order to accurately detect the effects of multiple mixed admixtures on the strength and slump of concrete, a weighing device is required during mixing. The existing concrete mixer weighing device has poor seismic resistance and has a significant amplitude under the vibration generated by the mixer, which can easily cause the mixer placed on it to deviate from the center of the weighing plate, causing the center of gravity of the weighing device to shift, affecting the accuracy of the weighing sensor data measurement. At the same time, the vibration will affect the data acquisition of the weighing sensor, causing the data to fluctuate significantly, resulting in the inability to achieve real-time weighing. Utility Model Content

[0003] In view of the deficiencies existing in the related art, the utility model provides a weighing device for a mixer to solve the problem that the current weighing device for a mixer has poor anti-vibration effect and the vibration generated can easily cause the mixer to deviate from the center of the weighing plate, affecting the measurement accuracy.

[0004] The utility model provides a weighing device for a mixer, comprising:

[0005] Weighing board;

[0006] The base has weighing sensors installed on both sides of the base, and the weighing plates are respectively placed on the weighing sensors;

[0007] A first limiting assembly, the first limiting assembly comprises a first limiting rod and two first connecting seats respectively installed at both ends of the first limiting rod, the first limiting rod is arranged longitudinally, and the two first connecting seats are respectively fixedly installed on the weighing plate and the base;

[0008] The second limiting assembly includes a second limiting rod and two second connecting seats respectively installed at both ends of the second limiting rod. The second limiting rod is arranged horizontally, and the two second connecting seats are respectively fixedly installed on the weighing plate and the base.

[0009] In the technical solution, a weighing sensor is provided between the weighing plate and the base, and the first limit assembly and the second limit assembly respectively connect the weighing plate and the base in the longitudinal and transverse directions. When the mixer is working, the vibration acting on the weighing plate is suppressed by the first limit rod and the second limit rod, so as to limit the amplitude of the weighing plate in the longitudinal and transverse directions, and avoid the mixer from shifting due to vibration, thereby ensuring the accuracy of the weighing data of the weighing sensor. In addition, the mixer will not shift, so there is no need to reset the mixer, so that the mixer can work continuously and the weighing sensor can perform weighing in real time.

[0010] In some of the embodiments, the weighing plate includes a plate body and two load-bearing beams respectively installed on both sides of the plate body. Two weighing sensors are longitudinally arranged on both sides of the base, and the two ends of the load-bearing beam are respectively mounted on the two weighing sensors on the corresponding side.

[0011] In this technical solution, two load-bearing beams are installed on both sides of the plate body to increase the contact area between the plate body and the weighing sensor, and improve the stability of the connection between the plate body and the weighing sensor. At the same time, the plate body is connected to the weighing sensor through the load-bearing beam. When the connection part is worn and needs repair, it is only necessary to replace the corresponding load-bearing beam without replacing the entire plate body, thus saving materials.

[0012] In some of the embodiments, the weighing plate has legs at four corners, and each leg is located above a corresponding weighing sensor.

[0013] In the technical solution, there is a corresponding support leg above each weighing sensor, and the weighing plate is connected to the weighing sensor through the support legs so that the force can be concentrated above the weighing sensor during the transmission process, thereby ensuring the accuracy of the weighing sensor measurement data.

[0014] In some of the embodiments, the load-bearing beam is divided into a middle beam and two end seats respectively installed at both ends of the middle beam, the two end seats are respectively mounted on corresponding weighing sensors, and the middle beam is an I-beam.

[0015] In this technical solution, the load-bearing beam is divided into an intermediate beam and end seats at both ends. The modular design facilitates later maintenance and replacement without replacing the entire load-bearing beam, saving materials and facilitating disassembly and assembly by maintenance personnel. In addition, the intermediate beam is made of I-beam, which not only meets the strength requirements but also facilitates processing and manufacturing such as opening holes, saving manpower and material resources.

[0016] In some of the embodiments, the end seats cover the top surfaces of the corresponding weighing sensors to prevent materials from falling onto the upper surfaces of the weighing sensors.

[0017] In this technical solution, the end seat can play a protective role on the weighing sensor, preventing splashing materials from dripping onto the weighing sensor and affecting the weighing accuracy of the weighing sensor, and also preventing the materials from corroding the weighing sensor.

[0018] In some of the embodiments, the end seat is in a stepped shape, and the weighing sensor is disposed below the table surface of the end seat so that the top surface of the weighing sensor is higher than the bottom surface of the end seat.

[0019] In this technical solution, by placing the weighing sensor under the step-shaped end seat, the weighing sensor and the end seat partially overlap vertically to avoid the load-bearing beam and the floor being too high, thereby lowering the center of gravity of the device and improving the stability of the device during weighing.

[0020] In some of the embodiments, the weighing sensor includes a sensor base and a sensor assembly mounted thereon, the top of the sensor assembly is connected to the end seat, and also includes a limit bolt, which passes through a limit hole set in the table top and is connected to the sensor base to fix the end seat and the weighing sensor in the horizontal direction.

[0021] In this technical solution, the limit bolt is passed through the limit hole set in the table top and then connected to the sensor base, which can keep the end seat and the weighing sensor relatively fixed in the horizontal direction. At the same time, it can also enhance the stability of the connection between the weighing sensor and the end seat, and avoid the vibration generated during weighing that causes the two to be disconnected.

[0022] In some embodiments, the first limiting rod and the second limiting rod are both shock absorbers.

[0023] In the present technical solution, the first limit rod and the second limit rod are both telescopic rods with retractable rod bodies, which can offset the vibration transmitted to the weighing plate by the mixer through their own extension and retraction, thereby reducing the shaking amplitude of the weighing plate when the mixer is working, making the weighing plate more stable when the weighing sensor is measuring, thereby ensuring the accuracy of the measurement data.

[0024] In some embodiments, both ends of the first limiting rod are hinged to the corresponding first connecting seat, and both ends of the second limiting rod are hinged to the corresponding second connecting seat.

[0025] In the present technical solution, the first and second limit rods are respectively connected to the first and second connecting seats by a hinged manner, so that the connecting parts can have the ability to rotate slightly, providing a certain buffer for the connecting parts and the limit rods connected thereto during vibration, reducing the wear of components caused by vibration and increasing the service life of components.

[0026] In some of the embodiments, the base is divided into a first base and a second base, a separation space is provided between the first base and the second base, and weighing sensors are respectively installed on the first base and the second base.

[0027] In the present technical solution, the base is divided into a first base and a second base and arranged at intervals, which can reduce the volume of the base, save materials, reduce the overall weight of the device, facilitate the transportation of the device, and also reduce the requirements for the site when the device is installed, avoiding uneven areas on the site that make it impossible to place the integrated base. At the same time, it can also free up space under the weighing plate to facilitate the installation of unloading devices such as conveyor belts, thereby maximizing space utilization.

[0028] Based on the above technical solution, a weighing sensor is provided between the weighing plate and the base, the first limit assembly connects the base and the load-bearing beam arranged under the weighing plate body in the longitudinal direction, and the second limit assembly directly connects the weighing plate body and the base in the transverse direction. When the mixer is working, the vibration acting on the weighing plate is suppressed by the first and second limit assemblies acting directly or indirectly on the plate body, thereby limiting the longitudinal and transverse amplitude of the weighing plate to avoid the mixer from shifting due to vibration, thereby ensuring the accuracy of the weighing data of the weighing sensor. In addition, the mixer will not shift, so there is no need to reset the mixer, so that the mixer can work continuously and the weighing sensor can perform weighing in real time.

[0038] As shown in the figure, in an illustrative embodiment of the weighing device for a mixer of the utility model, the weighing device for a mixer includes a weighing plate 1, a base 2, a weighing sensor 3, a first limit assembly 4 and a second limit assembly 5.

[0039] Weighing plate 1;

[0040] A base 2, with weighing sensors 3 installed on both sides of the base 2, and both sides of the weighing plate 1 are respectively placed on the weighing sensors 3;

[0041] The first limiting assembly 4 includes a first limiting rod 401 and two first connecting seats 402 respectively installed at both ends of the first limiting rod 401. The first limiting rod 401 is arranged longitudinally, and the two first connecting seats 402 are respectively fixedly installed on the weighing plate 1 and the base 2;

[0042] The second limiting assembly 5 includes a second limiting rod 501 and two second connecting seats 502 respectively installed at both ends of the second limiting rod 501. The second limiting rod 501 is arranged horizontally, and the two second connecting seats 502 are respectively fixedly installed on the weighing plate 1 and the base 2.

[0043] In the above-mentioned schematic embodiment, both sides of the weighing plate 1 are respectively mounted on the weighing sensors 3 arranged on both sides of the base 2, and the first limit assembly 4 and the second limit assembly 5 respectively connect the weighing plate 1 and the base 2 in the longitudinal and transverse directions, wherein the first limit rod 401 and the second limit rod 501 in the first limit assembly 4 and the second limit assembly 5 are telescopic rods. When the mixer is working, the vibration acting on the weighing plate 1 is offset by the telescopic movement of the first limit rod 401 and the second limit rod 501 themselves, thereby limiting the longitudinal and transverse amplitude of the weighing plate 1, avoiding the mixer from shifting due to vibration, thereby ensuring the accuracy of the weighing data of the weighing sensor 3. In addition, the mixer will not shift, so there is no need to shut down the mixer for resetting, so that the mixer can work continuously and the weighing sensor 3 can weigh in real time.

[0044] In some embodiments, the weighing plate 1 includes a plate body 101 and two load-bearing beams 102 respectively installed on both sides of the plate body 101, two load cells 3 are longitudinally arranged on both sides of the base 2, and the two ends of the load-bearing beam 102 are respectively placed on the two load cells 3 on the corresponding side. Installing two load-bearing beams 102 on both sides of the plate body 101 can increase the contact area between the plate body 101 and the load cells 3, and improve the stability of the connection between the plate body 101 and the load cells 3. Two load cells 3 are longitudinally arranged on both sides of the base 2, and four load cells 3 are arranged at the four corners of the base 2, which can evenly bear the weight from the weighing plate 1 and the mixer, and can reduce and eliminate the error of data measurement. At the same time, the plate body 101 is connected to the load cells 3 through the load-bearing beams 102. When the connection part is worn and needs to be repaired, only the corresponding load-bearing beams 102 need to be replaced, and there is no need to replace the entire plate body 101, saving materials.

[0045] In some embodiments, the weighing plate 1 has legs 6 at all four corners, and each leg 6 is located above a corresponding weighing sensor 3. There is a corresponding leg 6 above each weighing sensor 3. The weighing plate 1 is connected to the weighing sensor 3 through the legs 6, so that the force can be concentrated above the weighing sensor 3 during the transmission process, ensuring the accuracy of the measurement data of the weighing sensor 3. The legs 6 are four-sided prisms with right-angled trapezoidal sides, and the long bottom is connected to the weighing plate 1, so as to increase the contact area between the legs 6 and the weighing plate 1 and improve the stability of the support for the weighing plate 1.

[0046] In some embodiments, the load-bearing beam 102 is divided into a middle beam 1021 and two end seats 1022 respectively installed at both ends of the middle beam 1021. The two end seats 1022 are respectively set on the corresponding weighing sensors 3, and the middle beam 1021 is an I-beam. The load-bearing beam 102 is divided into the middle beam 1021 and the end seats 1022 arranged at both ends. The modular design is convenient for later maintenance and replacement. There is no need to replace the entire load-bearing beam 102, which saves materials and is also convenient for maintenance personnel to disassemble and assemble. In addition, the middle beam 1021 is made of I-beam, which not only meets the strength requirements but also facilitates processing and manufacturing such as opening holes, saving manpower and material resources.

[0047] In some embodiments, the end seats 1022 cover the top surface of the corresponding weighing sensor 3 to prevent materials from falling onto the upper surface of the weighing sensor 3. The end seats 1022 can protect the weighing sensor 3, prevent splashing materials from dripping onto the weighing sensor 3, and affect the weighing accuracy of the weighing sensor 3, and also prevent materials from corroding the weighing sensor 3.

[0048] In some embodiments, the end seat 1022 is in a stepped shape, and the weighing sensor 3 is disposed below the table 7 of the end seat 1022, so that the top surface of the weighing sensor 3 is higher than the bottom surface of the end seat 1022. The weighing sensor 3 is placed in the lower space of the stepped end seat 1022, and the weighing sensor 3 partially overlaps with the side of the end seat 1022 in the vertical direction, so that the load-bearing beam 102 connected to the side of the end seat 1022 does not need to be disposed at the top position of the weighing sensor 3, and the load-bearing beam 102 is prevented from being too high from being spaced from the bottom plate, thereby lowering the center of gravity of the device and improving the stability of the device during weighing.

[0049] In some embodiments, the weighing sensor 3 includes a sensor base 301 and a sensor assembly 302 mounted thereon, the top of the sensor assembly 302 is connected to the end seat 1022, and also includes a limit bolt 8, the limit bolt 8 is passed through the limit hole 9 provided on the table 7 and connected to the sensor base 301, and is used to fix the end seat 1022 and the weighing sensor 3 in the horizontal direction. The limit bolt 8 is passed through the limit hole 9 provided on the table 7 and connected to the sensor base 301, wherein the weighing sensor 3 is provided with limit bolts 8 on both sides of the sensor assembly 302, and the limit bolts 8 on both sides are movably connected with the corresponding limit holes 9, in the horizontal direction, the end seat 1022 and the weighing sensor 3 can remain relatively fixed, thereby enhancing the stability of the connection between the weighing sensor 3 and the end seat 1022, and avoiding the vibration generated during weighing to disconnect the two, in the vertical direction, the end seat 1022 can move up and down along the limit bolt 8, thereby not affecting the downward displacement generated by the top weighing plate 1 and other components when the weighing sensor 3 is weighed.

[0050] In some embodiments, the first limit rod 401 and the second limit rod 501 are both shock absorbers. The first limit rod 401 and the second limit rod 501 are both telescopic rods with retractable rod bodies, which can offset the vibration transmitted to the weighing plate 1 by the mixer through their own extension and contraction, reduce the shaking amplitude of the weighing plate 1 when the mixer is working, make the weighing plate 1 more stable when the weighing sensor 3 is measuring, and ensure the accuracy of the measurement data.

[0051] In some embodiments, both ends of the first limiting rod 401 are hinged to the corresponding first connection seat 402, and both ends of the second limiting rod 501 are hinged to the corresponding second connection seat 502. The first limiting rod 401 and the second limiting rod 501 are respectively connected to the first connection seat 402 and the second connection seat 502 by hinged connection, so that the connection part can be slightly rotated, and a certain buffer is provided for the connection part and the limiting rod connected thereto during vibration, so as to reduce the wear of the components caused by vibration and improve the service life of the components.

[0052] In some embodiments, the base 2 is divided into a first base 201 and a second base 202, and a spacing space is provided between the first base 201 and the second base 202, and the first base 201 and the second base 202 are respectively installed with weighing sensors 3. Dividing the base 2 into the first base 201 and the second base 202 and arranging them at intervals can reduce the volume of the base 2, save materials, reduce the overall weight of the device, facilitate the transportation of the device, and also reduce the requirements for the site when the device is installed, avoiding the unevenness of the site that makes it impossible to place the integrated base 2. At the same time, it can also make room for the bottom of the weighing plate 1, which is convenient for installing unloading devices such as conveyor belts, so as to maximize the use of space.

[0053] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0054] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
