Description

Technical Field

[0001] The present application relates to the technical field of aggregate scale calibration, and in particular to an aggregate scale calibration device and an aggregate mixer. Background Art

[0002] Aggregate mixer is a machine that mixes cement, sand and gravel aggregates and water to make concrete mixture. Aggregate mixer includes aggregate frame and hopper installed on the aggregate frame. In order to get the accurate amount of aggregate, it is necessary to weigh the aggregate. Therefore, an aggregate scale, such as an aggregate weighing sensor, is set between the hopper and the aggregate frame. In order to weigh the aggregate more accurately, the accuracy of the aggregate scale needs to be calibrated regularly or irregularly.

[0003] In the related art, the method of calibrating the aggregate scale is to manually hang 20kg weights on the hook of the hopper, or place the weights inside the hopper. The gravity of the weights acts on the hopper, and the aggregate is weighed. If the weight is consistent with the weight of the weights, the aggregate scale is accurate. If the weight is inconsistent with the weight of the weights, the aggregate scale is inaccurate.

[0004] In the related art, the weights are stacked according to the calibration value, which requires moving a large number of weights. The whole process of moving and stacking the weights is labor-intensive and has huge safety risks. There are five aggregate scales, and it takes five workers a day to calibrate them once. Therefore, the efficiency of the calibration of aggregate scales in the related art is low. Utility Model Content

[0037] In the description of the present application, it should be noted that the terms "first", "second", "third", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0038] In the description of the present application, it should be noted that the terms “vertical”, “horizontal”, “top surface”, “bottom surface”, etc. are all based on the viewing angle of the corresponding view.

[0039] See also Figure 1-Figure 3 The present application provides an aggregate scale calibration device, which includes a hanger 1, a calibration gravity sensor 2, an elastic telescopic component 3 and a force-applying component 4.

[0040] The bracket 1 can be connected to the hopper 51 of the aggregate mixer body 5; the elastic telescopic component 3 is installed on the bracket 1; one end of the force-applying component 4 is connected to the aggregate mixer body 5, and the other end is connected to the elastic telescopic component 3, and the force-applying component 4 can apply a force in the same direction as the gravity of the hopper 51 of the aggregate mixer body 5 to the elastic telescopic component 3; the calibration gravity sensor 2 is installed between the bracket 1 and the elastic telescopic component 3, or the calibration gravity sensor 2 is installed between the force-applying component 4 and the aggregate mixer body 5.

[0041] Please see again Figure 1 In one embodiment, the calibration gravity sensor 2 is installed between the hanger 1 and the elastic telescopic component 3.

[0042] Please see again Figure 2 In another embodiment, the calibration gravity sensor 2 is installed between the force-applying component 4 and the aggregate mixer body 5 .

[0043] The calibration gravity sensor 2 is a conventional product, and the circuit connection, installation method and working principle of the calibration gravity sensor 2 are all known to those skilled in the art. For example, the calibration gravity sensor 2 can be the same model as the aggregate weighing sensor.

[0044] When it is necessary to calibrate the aggregate scale of the aggregate mixer body 5, according to the calibration value, the force-applying component 4 applies a force in the same direction as the gravity direction of the hopper 51 of the aggregate mixer body 5 to the elastic telescopic component 3, that is, the force-applying component 4 applies a vertically downward force to the elastic telescopic component 3, and the vertically downward force is transmitted to the calibration gravity sensor 2 and the bracket 1. Since the bracket 1 is connected to the hopper 51 of the aggregate mixer body 5, the vertically downward force applied by the force-applying component 4 finally acts on the hopper 51.

[0045] During this process, the calibration gravity sensor 2 can measure the magnitude of the vertical downward force applied by the force-applying component 4. When the force measured by the calibration gravity sensor 2 reaches the calibration value, check whether the force measured by the calibration gravity sensor 2 is consistent with the force measured by the aggregate weighing sensor on the hopper 51. If the force measured by the calibration gravity sensor 2 is consistent with the force measured by the aggregate weighing sensor on the hopper 51, the aggregate scale is determined to be accurate; if the force measured by the calibration gravity sensor 2 is inconsistent with the force measured by the aggregate weighing sensor on the hopper 51, the aggregate scale is determined to be inaccurate and the aggregate scale needs to be adjusted.

[0046] In this way, the force-applying component 4 applies a vertical downward force instead of adding weights into the hopper 51, and the calibration gravity sensor 2 can accurately measure the magnitude of the vertical downward force applied by the force-applying component 4. There is no need to manually carry the weights one by one into the hopper 51, and the time for calibrating the aggregate scale is relatively short. Therefore, the labor intensity of personnel can be reduced, the efficiency of the aggregate scale calibration can be improved, and the safety risks in the aggregate scale calibration process can be reduced.

[0047] Based on the above design, this embodiment applies a force in the same direction of gravity to the hopper 51 of the aggregate mixer body 5 through the force-applying component 4, which can replace manual placement of weights in the hopper 51, thereby greatly reducing labor intensity and greatly improving the calibration efficiency of the aggregate scale.

[0048] In some embodiments, see Figure 1-Figure 4 The elastic telescopic component 3 includes a sliding rod 34 , a first sliding plate 31 , a second sliding plate 33 and a telescopic spring 32 .

[0049] One end of the sliding rod 34 is connected to the bracket 1, and the other end is connected to the aggregate mixer body 5. The sliding rod 34 is located in the vertical direction; the first sliding plate 31 is slidably connected to the sliding rod 34, and the bottom surface of the first sliding plate 31 contacts the top surface of the calibration gravity sensor 2; the second sliding plate 33 is slidably connected to the sliding rod 34; the telescopic spring 32 is sleeved on the sliding rod 34, and one end of the telescopic spring 32 is connected to the top surface of the first sliding plate 31, and the other end is connected to the bottom surface of the second sliding plate 33.

[0050] When the calibration gravity sensor 2 is installed between the hanger 1 and the elastic telescopic assembly 3, the bottom surface of the first sliding plate 31 contacts the top surface of the calibration gravity sensor 2. The first sliding plate 31 and the second sliding plate 33 are clearance-fitted, and the first sliding plate 31 and the second sliding plate 33 can slide in the vertical direction along the slide bar 34. When the force-applying assembly 4 applies a vertical downward force to the second sliding plate 33, the vertical downward force is transmitted to the telescopic spring 32, the first sliding plate 31, the calibration gravity sensor 2, the hanger 1 and the hopper 51.

[0051] During this process, the first sliding plate 31 and the second sliding plate 33 will slide downward along the slide bar 34, and the telescopic spring 32 will be gradually compressed as the force applied by the force-applying component 4 gradually increases. According to Hooke's law, when the stiffness coefficient of the telescopic spring 32 is known, the telescopic spring 32 can be quickly compressed by a certain amount, so that the force-applying component 4 can quickly apply a force of a corresponding calibration value to the hopper 51, thereby further improving the calibration efficiency of the aggregate scale.

[0052] In some embodiments, please refer again to Figure 1 , Figure 2 and Figure 4 The elastic telescopic component 3 also includes a mounting seat 7, which is mounted on the hanger 1, and the lower end of the slide rod 34 is connected to the mounting seat 7.

[0053] The lower end of the slide rod 34 extends into the mounting seat 7, and the mounting seat 7 can be mounted on the bracket 1 by bolts. Since the mounting seat 7 can be mounted on the bracket 1 more stably, the elastic telescopic component 3 and the force-applying component 4 can be more stably mounted on the bracket 1 through the mounting seat 7.

[0054] In some embodiments, please refer again to Figure 1-Figure 4 The elastic telescopic component 3 also includes a connecting plate 9, which contacts the aggregate mixer body 5, the upper end of the slide rod 34 is connected to the connecting plate 9, and the force-applying component 4 is connected to the aggregate mixer body 5 through the connecting plate 9.

[0055] When the calibration gravity sensor 2 is installed between the force applying assembly 4 and the aggregate mixer body 5, the calibration gravity sensor 2 is installed on the top surface of the connecting plate 2. When the hanger 1 is hung on the aggregate mixer body 5, the calibration gravity sensor 2 is stuck between the connecting plate 9 and the aggregate mixer body 5.

[0056] When the calibration gravity sensor 2 is installed between the hanger 1 and the elastic telescopic assembly 3 , when the hanger 1 is hung on the aggregate mixer body 5 , the connecting plate 9 is clamped between the slide bar 34 and the aggregate mixer body 5 .

[0057] When the hanger 1 is removed from the aggregate mixer body 5, the entire calibration device can be removed from the aggregate mixer body 5, thereby making it easier to install and disassemble the calibration device.

[0058] Preferably, the connecting plate 9 can also be connected to the aggregate mixer body 5 by bolts.

[0059] In some embodiments, please refer again to Figure 4 The force-applying assembly 4 includes a hydraulic servo cylinder or an electric push rod 41 , which is mounted on the top surface of the second sliding plate 33 , and a piston rod of the hydraulic servo cylinder or the electric push rod 41 is connected to the connecting plate 9 .

[0060] The hydraulic servo cylinder and the electric push rod 41 are both conventional products, and the circuit connection, control method, installation method and working principle of the hydraulic servo cylinder or the electric push rod 41 are all known to those skilled in the art. Since the piston rod of the hydraulic servo cylinder or the electric push rod 41 is connected to the connecting plate 9, when the piston rod of the hydraulic servo cylinder or the electric push rod 41 is extended, the hydraulic servo cylinder or the electric push rod 41 will apply a vertical downward thrust to the second sliding plate 33, and the hydraulic servo cylinder or the electric push rod 41 and the second sliding plate 33 will move downward along the slide rod 34 as a whole. In this way, it is easier to apply a downward force to the hopper 51 through the hydraulic servo cylinder or the electric push rod 41, so that it is easier to calibrate the aggregate scale.

[0061] In some embodiments, please refer again to Figure 4 The verification device also includes a third sliding plate 8 slidably connected to the sliding rod 34, the piston rod of the hydraulic servo cylinder or the electric push rod 41 passes through the third sliding plate 8 and is connected to the connecting plate 9, and at least part of the electric push rod 41 is connected to the bottom surface of the third sliding plate 8.

[0062] This embodiment of Figure 4 In the example, the force-applying assembly 4 includes an electric push rod 41, and the rotary motor of the electric push rod 41 is installed on the bottom surface of the third sliding plate 8. When the piston rod of the electric push rod 41 extends, the third sliding plate 8, the second sliding plate 33 and the electric push rod 41 move downward as a whole. In this way, the stability of the electric push rod 41 can be improved by the third sliding plate 8.

[0063] Preferably, see again Figure 4 , the number of the slide bars 34 is multiple, for example, Figure 4 There are two middle sliding rods 34 , so that the first sliding plate 31 , the second sliding plate 33 , the third sliding plate 8 and the force applying assembly 4 can move more stably along the sliding rods 34 .

[0064] In some embodiments, see Figure 1 and Figure 5 The hanger 1 includes a crossbeam 12 and a hanger plate 11 connected to the top surface of the crossbeam 12, and the hanger plate 11 is connected to the aggregate mixer body.

[0065] The crossbeam 12 is located in the horizontal direction, the hanging plate 11 is located in the vertical direction, and the mounting seat 7 in the elastic telescopic component 3 is installed on the top surface of the crossbeam 12. When the calibration gravity sensor 2 is installed between the hanging bracket 1 and the elastic telescopic component 3, the calibration gravity sensor 2 is installed on the top surface of the crossbeam 12. The crossbeam 12 and the hanging plate 11 can be connected by bolts. In this way, it is easier to install the calibration gravity sensor 2 and the elastic telescopic component 3.

[0066] Preferably, there are multiple hanging boards 11, for example, Figure 5 The number of the middle hanging plates 11 is two, so that the hanging bracket 1 can be installed on the aggregate mixer body 5 more stably.

[0067] In some embodiments, see Figure 6 A hanging opening 111 is formed on the upper portion of the hanging plate 11 , and the hanging plate 11 is hung on the hook 52 of the aggregate mixer body 5 through the hanging opening 111 .

[0068] The hanging opening 111 on the hanging plate 11 matches with the hook 52 on the aggregate mixer body 5. The hanging opening 111 makes it easier to hang the hanger 1 on the aggregate mixer body 5 and remove the hanger 1 from the aggregate mixer, thereby making it easier to remove the calibration device from the aggregate mixer body 5.

[0069] In some embodiments, the present application further provides an aggregate mixer, which includes the aggregate scale calibration device 6 in the present application. By installing the aggregate scale calibration device 6 in the present application on the aggregate mixer body 5 to form an aggregate mixer, it is more convenient to calibrate the aggregate scale of the aggregate mixer.

[0070] The above are only various implementations of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
