Description

Technical Field

[0001] This utility model relates to the field of cement paving vehicle technology, and more specifically, it relates to an intelligent cement paving vehicle weighing and metering batching system. Background Technology

[0002] A cement paver is a self-propelled unit used for the construction of cement concrete pavements. It is equipped with functions such as paving, compacting, and leveling of concrete mixtures. The amount of cement concrete to be paved for a specific road section is weighed and batched by the weighing and metering system on the cement paver.

[0003] In the existing technology, the weighing of cement concrete paving volume relies on the weighing hopper in the cement paver truck, which serves as the weighing and metering batching system in the cement paver truck.

[0004] However, the weighing hopper has a drawback in actual use: low weighing accuracy. When the appropriate weight of concrete is weighed in the hopper, the actual weight of concrete output to the road paving is lower than the weight of concrete in the hopper. This low accuracy is due to the fact that when the cement paver is transporting concrete, the concrete tends to stick to the inner walls of the weighing hopper and the inner walls of the concrete conveying plate and other machinery. The degree of sticking varies depending on external environmental factors and the characteristics of the concrete itself. Therefore, it is difficult to pre-weigh the appropriate weight of cement concrete to be paved in the weighing hopper. Thus, there is room for improvement in the mechanical structure of the weighing and metering batching system for cement pavers. Utility Model Content

[0005] In view of the shortcomings of the existing weighing hopper in the background art, which has low weighing accuracy in actual use, this utility model is equipped with a pre-weighing and metering component and a continuous weighing and metering component, which improves the accuracy and reliability of the weighing and metering system and greatly optimizes the operation quality of cement pavers.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A smart cement paver weighing and metering batching system includes: a pre-weighing and metering component and a continuous weighing and metering component;

[0008] The pre-weighing and metering component includes a weighing hopper, a hopper support, and a first weighing sensor. The weighing hopper is installed on the top of the hopper support, and the first weighing sensor is used to measure the downward pressure of the weighing hopper on the hopper support.

[0009] The continuous weighing and metering component includes a concrete conveying assembly, a continuous weighing assembly, and a discharge assembly. The concrete conveying assembly is used to transport cement concrete released from the weighing hopper. The continuous weighing assembly includes a support column, a weighing plate, and a second weighing sensor. The weighing plate is installed on the top of the support column and is inclined. The second weighing sensor is installed between the support column and the weighing plate and is used to dynamically weigh the concrete conveyed on the weighing plate. The output end of the inclined weighing plate conveys cement concrete to the discharge assembly.

[0010] The discharge assembly is used to transport the cement concrete released from the weighing plate.

[0011] The method of using the intelligent cement paver weighing and metering batching system of this utility model, based on the above technical solution, is as follows: A first weighing sensor weighs the hopper body, and the weighing result of the first weighing sensor is set to be greater than the weight of cement concrete to be laid in the road section to be paved. Then, a second weighing sensor continuously weighs the actual weight of cement concrete to be laid in the road section to be paved, and the weight of cement concrete measured by the second weighing sensor is set to be equal to the weight of cement concrete to be laid in the road section to be paved. The second weighing sensor dynamically weighs the concrete transported on the weighing plate, and the weighing data is transmitted to the central back-end controller of the cement paver. The data is integrated over time to calculate the total integrated weight value within the continuous concrete conveying cycle. The output end of the tilted weighing plate conveys cement concrete to the discharge assembly.

[0012] The purpose of setting up the first sensor is to prevent the second weighing sensor from making measurement errors, to control the total amount of concrete, and to improve the reliability of the entire weighing and metering batching system.

[0013] Furthermore, the present invention includes a weighing hopper comprising a hopper body and a discharge port, the discharge port being located at the bottom of the hopper body, and a first weighing sensor being located between the hopper support and the hopper body to measure the downward pressure exerted by the hopper body on the hopper support, thereby converting it into the weight of the hopper body.

[0014] Furthermore, the present invention states that the concrete conveying assembly is constructed using an inclined flatbed conveyor or a belt conveyor.

[0015] Furthermore, the concrete conveying assembly includes a rotating shaft and a conveyor belt. The rotating shaft rotates under the drive of an external motor, which in turn drives the conveyor belt to rotate and convey cement concrete. The conveyor belt is located below the discharge port, and the output end of the conveyor belt conveys cement concrete to the continuous weighing assembly.

[0016] Furthermore, the present invention states that the discharge assembly is a flat plate conveyor with an inclined arrangement, or a belt conveyor.

[0017] In summary, this utility model has the following beneficial effects:

[0018] This utility model is equipped with a pre-weighing and metering component and a continuous weighing and metering component, which improves the accuracy and reliability of the weighing and metering system and greatly optimizes the operation quality of cement pavers.

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0023] A smart cement paver weighing and metering batching system, combined with Figure 1 and Figure 2 As shown, the system includes a pre-weighing and metering unit 100 and a continuous weighing and metering unit 200. The pre-weighing and metering unit 100 weighs the amount of cement concrete exceeding the road paving standard and supplies the concrete to the continuous weighing and metering unit 200. The continuous weighing and metering unit 200 continuously weighs the concrete during transportation until the total weight of transported concrete meets the road paving standard, at which point it stops supplying cement concrete.

[0024] The pre-weighing and metering component 100 includes a weighing hopper 101, a hopper support 102, and a first weighing sensor 103. The weighing hopper 101 is installed on the top of the hopper support 102, which supports the weighing hopper 101. The weighing hopper 101 includes a hopper body 1011 and a discharge port 1012. The discharge port 1012 is located at the bottom of the hopper body 1011. The hopper support 102 is fixed to the periphery of the hopper body 1011 for support. The first weighing sensor 103 is located between the hopper support 102 and the hopper body 1011 and is used to measure the downward pressure of the hopper body 1011 on the hopper support 102, and then convert it into the weight of the hopper body 1011.

[0025] The continuous weighing and metering component 200 includes a concrete conveying component 201, a continuous weighing component 202, and a discharge component 203. The concrete conveying component 201 is used to transport cement concrete released from the discharge port 1012 of the hopper body 1011. It can be conveyed using an inclined flat plate or a belt conveyor. In this embodiment of the invention, a belt conveyor is used as an example. The concrete conveying component 201 includes a rotating shaft 2011 and a conveyor belt 2012.

[0026] The continuous weighing assembly 202 includes a support column 2021, a weighing plate 2022, and a second weighing sensor 2023. The weighing plate 2022 is installed at the top of the support column 2021 and is inclined. The second weighing sensor 2023 is installed between the support column 2021 and the weighing plate 2022. The second weighing sensor 2023 is used to dynamically weigh the concrete transported on the weighing plate 2022. The weighing data is transmitted to the central back-end controller of the cement paver, where it is integrated over time to calculate the total integrated weight value within the continuous concrete transport cycle. The output end of the inclined weighing plate 2022 conveys cement concrete to the discharge assembly 203.

[0027] The discharge assembly 203 can be a tilted flatbed conveyor or a belt conveyor. In this embodiment of the invention, a belt conveyor is used as an example.

[0028] The method of using the intelligent cement paver weighing and metering batching system of this utility model is as follows: A first weighing sensor 103 weighs the hopper body 1011, and the weighing result of the first weighing sensor 103 is set to be greater than the weight of cement concrete to be laid in the road section to be paved. Then, a second weighing sensor 2023 continuously weighs the actual weight of cement concrete to be laid in the road section to be paved, and the weight of cement concrete measured by the second weighing sensor 2023 is set to be equal to the weight of cement concrete to be laid in the road section to be paved.

[0029] The purpose of setting the first sensor 103 is to prevent the second weighing sensor 2023 from making measurement errors, to have a control function on the total amount of concrete, and to improve the reliability of the entire weighing and metering batching system.
