[0035] The present invention will be described in detail below with reference to specific embodiments.

[0036] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0037] like Figures 1 to 15As shown, this utility model provides an automated concrete bulk density testing device, including a temporary storage mechanism 3 and a conveying mechanism 4, as well as a testing mechanism 2 and a filling mechanism 1. The temporary storage mechanism 3 is used to store containers containing concrete, the conveying mechanism 4 is used to transfer containers containing concrete, the testing mechanism 2 is used to test the bulk density of concrete, and the filling mechanism 1 is used to fill the containers with concrete slurry.

[0038] The filling mechanism 1 includes a mixing component 10, a vibrating filling component 11, and a leveling component 12. The mixing component 10 is used to mix concrete slurry. The vibrating filling component 11 is located below the mixing component 10 and is used to place the container and fill the container with concrete by vibration. The leveling component 12 is used to scrape away excess concrete slurry in the container.

[0039] The testing mechanism 2 includes a bulk density weighing component, which includes a testing frame 20, a weighing rack 22, and a weighing sensor 21. The weighing rack 22 is positioned above the weighing sensor 21, and the weighing sensor 21 is fixedly connected to the testing frame 20. The container with excess concrete slurry scraped off is transferred to the weighing rack 22 for weighing under the conveying mechanism 4.

[0040] In this embodiment, the vibrating filler assembly 11 includes a fixed base 110, a vibrating frame 111, a vibrating device 112, a collection chamber 113, and a limiting frame 114. The vibrating frame 111 is mounted on the fixed base 110 via a spring frame 115. The vibrating device 112 is fixedly mounted on the vibrating frame 111. The collection chamber 113 is disposed on the vibrating frame 111. A groove 116 for placing the limiting frame 114 is provided in the collection chamber 113. The limiting frame 114 is used to place an empty container and is located directly below the stirring assembly 10.

[0041] In this embodiment, the mixing assembly 10 includes a mixing drive and a mixing chamber. The mixing drive is installed on the mixing chamber, and the mixing chamber is provided with a discharge port. Workers only need to put the raw materials into the mixing chamber in proportion and mix them with the mixing drive to output the required concrete slurry. Since the mixing assembly 10 is the prior art and is not an improvement of this embodiment, it is not described in this embodiment.

[0042] With the above design scheme, when a bulk density test is required, the tester puts the raw material into the mixing component 10, and the conveying mechanism 4 places the empty container in the limiting frame 114. The concrete slurry in the mixing component 10 flows out from the discharge port and falls into the empty container on the limiting frame 114. The vibration device 112 applies high-frequency vibration to the vibrating frame 111, so that the gaps in the concrete slurry falling into the container can be effectively filled, thereby making the concrete slurry in the container more compact.

[0043] In this embodiment, the leveling assembly 12 includes a leveling frame 120, a collection chamber 121, a lifting drive 122, and a leveling drive 123. The collection chamber 121 is fixedly installed on the leveling frame 120. A water pipe 125 is provided in the collection chamber 121 for placing a container filled with concrete, and a spray nozzle is provided on the water pipe 125. The lifting drive 122 is installed on the leveling frame 120 and is located above the collection chamber 121. The lifting drive 122 is used to drive the leveling drive 123 to rise or fall. A scraper 124 is installed at the bottom of the leveling drive 123, and the leveling drive 123 is used to drive the scraper 124 to rotate.

[0044] In this embodiment, wastewater drains are provided at the bottom of both the collection chamber 113 and the flow collection chamber 121. The wastewater drains are used to divert wastewater and excess fallen concrete slurry.

[0045] With the above design, after the container on the limiting frame 114 is filled with concrete slurry, the conveying mechanism 4 will automatically transfer the container to the water pipe 125. The water pipe 125 can fix the container. Then, the lifting drive 122 controls the leveling drive 123 to descend. As the leveling drive 123 descends, it drives the scraper 124 to rotate. The rotating scraper 124 will scrape off the excess concrete slurry on the top of the container. Then, the spray nozzle on the water pipe 125 sprays clean water to rinse the outside of the container, washing away the concrete slurry adhering to the outside of the container. Next, the conveying mechanism 4 will transfer the cleaned container to the weighing frame 22. The weighing sensor 21 at the bottom of the weighing frame 22 will automatically record information. Subtracting the data of the empty container from the recorded data will give the required bulk density information.

[0046] In this embodiment, the testing mechanism 2 further includes a setting detection component, which includes a pressure detection unit 24 and a testing platform 23. The testing platform 23 and the pressure detection unit 24 are disposed on the testing frame 20, with the pressure detection unit 24 located directly above the testing platform 23. The setting detection component is used to detect the degree of setting of concrete.

[0047] In this embodiment, a temporary placement rack 25 is also provided on the weighing rack 22. When testing is required, in order to test the reproducibility of the test data, the conveying mechanism 4 will simultaneously convey three or more containers to be tested, and the temporary placement rack 25 is provided to temporarily place the containers to be tested.

[0048] In this embodiment, the temporary storage mechanism 3 includes a temporary storage rack 30, on which multiple sets of extension platforms 31 are provided, and the extension platforms 31 are used to place containers.

[0049] In this embodiment, the conveying mechanism 4 includes a gripping robotic arm 40, a feeding assembly 41, and a container transfer assembly 42; the gripping robotic arm 40 is used to transfer and convey containers between the conveying mechanism 4, the detection mechanism 2, and the filling mechanism 1; the feeding assembly 41 is used to grip out containers from the temporary storage mechanism 3 or to put containers into the temporary storage mechanism 3; the container transfer assembly 42 is used to convey empty containers after demolding.

[0050] The gripping robotic arm 40 is a type of industrial robot that can automatically and precisely grip and place objects. Under program control, the gripping robotic arm 40 can pick up the container filled with concrete slurry on the limit frame 114 and transfer it to the water pipe 125. After the scraper 124 scrapes off the excess concrete slurry, the gripping robotic arm 40 transfers the scraped container to the weighing frame 22. After measurement, the container can be gripped by the gripping robotic arm 40 and transferred to the temporary storage mechanism 3.

[0051] In this embodiment, a gripping assembly 400 is provided on the gripping robotic arm 40. The gripping assembly 400 includes a connecting frame 401, an adjusting frame 402, and claws 403. The connecting frame 401 is connected to the gripping robotic arm 40. The adjusting frame 402 is disposed on the connecting frame 401. Two claws 403 are disposed on the adjusting frame 402, and the claws 403 can move on the adjusting frame 402.

[0052] In this embodiment, the gripper 403 is connected to the connecting frame 401 by screws. Operators can loosen the screws to adjust the spacing of the gripper 403, ensuring that the gripper 403 can fit the container. In this embodiment, a sensor is also installed on the adjusting frame 402. The sensor can automatically detect and position the container, ensuring that the gripper 403 can accurately grasp the container.

[0053] In this embodiment, the feeding assembly 41 includes a lateral moving part 410, a lifting part 411, an extension part 412, and a pick-and-place platform 413. The lateral moving part 410 drives the lifting part 411 to move laterally, the lifting part 411 drives the extension part 412 to rise or fall, the extension part 412 drives the pick-and-place platform 413 to extend or retract, and the pick-and-place platform 413 is used to place containers into the temporary storage mechanism 3 or to remove containers from the temporary storage mechanism 3. Since the feeding assembly 41 is prior art and not an improvement of this embodiment, it is not described in detail in this embodiment.

[0054] In this embodiment, the container transfer assembly 42 includes a transfer conveyor belt 420 and a transfer frame 421. The transfer frame 421 is provided with a pusher part 422. After demolding, the empty container is conveyed by the transfer conveyor belt 420 to the transfer frame 421, and then the pusher part 422 pushes the empty container to the gripping range of the gripping robot arm 40.

[0055] In this embodiment, both the weighing sensor 21 and the pressure detection unit 24 can send the detected data to the main control computer via a network.

[0056] The automated concrete bulk density testing device provided by this utility model, compared with the prior art, only requires the user to put the raw materials into the mixing component 10 in proportion. The mixing component 10 can automatically mix the raw materials evenly and transport the mixed concrete slurry to the empty container in the vibrating filler component 11. At the same time as the transport, the vibrating device 112 continuously applies high-frequency vibration to the container, so that the air bubble in the slurry can be released. After the filling is completed, the clamping robotic arm 40 transfers the mold containing the slurry to the leveling component 12 for leveling, and finally transfers it to the testing mechanism 2 for bulk density testing.

[0057] Where there is no conflict, the above embodiments and features can be combined with each other.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
