[0069] The above is the first embodiment of a concrete specimen forming device provided in the embodiments of the present application, and the following is the second embodiment of a concrete specimen forming device provided in the embodiments of the present application.

[0071] In an optional embodiment, the concrete specimen forming apparatus further includes: a discharge pipe 31, a discharge hopper 36, and an outlet baffle 29; the feed end of the discharge pipe 31 is connected to the concrete mixer; the discharge hopper 36 is mounted on a mounting frame and aligned with the discharge end of the discharge pipe 31; and the outlet baffle 29 is disposed at the discharge end of the discharge pipe 31. It should be noted that the discharge hopper 36 is mounted on the mounting frame, and after the forming mold 40 is transferred to the discharge hopper 36 via the transfer module 41, the concrete mixture flows into the forming mold 40 through the discharge pipe 31 and the discharge hopper 36. Furthermore, to prevent the concrete mixture from overflowing during the discharge process, an outlet baffle 29 is disposed at the discharge end of the discharge pipe 31.

[0072] Optionally, in order to ensure that the amount of concrete mixture discharged is appropriate during discharge, a concrete flow meter 30 is provided on the discharge pipe 31 for measuring the flow of the concrete mixture.

[0073] Specifically, the vibration module includes a loading platform and a vibration spring 35. The loading platform is positioned below the discharge hopper 36, and the vibration spring 35 is positioned below the loading platform. It is understood that the conveyor module 41 includes a first conveyor belt and a second conveyor belt, with the loading platform positioned between the first and second conveyor belts. The forming mold 40 passes through the first conveyor belt and reaches the loading platform. After the concrete mixture is placed on the loading platform, it is transferred to the second conveyor belt. Specifically, the loading platform in this embodiment comprises a plurality of rollers 34 arranged along the conveying direction of the conveyor belt. Specifically, a single roller 34 is arranged horizontally, and a plurality of rollers 34 are arranged along the conveying direction of the conveyor module 41.

[0074] Exemplarily, the tamping module in this embodiment includes a telescopic pneumatic pump 32 and a rotatable tamping rod 33. The telescopic pneumatic pump 32 is mounted on a mounting frame, and the output end of the telescopic pneumatic pump 32 is connected to the rotatable tamping rod 33. The rotatable tamping rod 33 extends through a discharge hopper 36. The rotatable tamping rod 33 can rotate from outside to inside. Optionally, the tamping rod rotation axis 10 of the rotatable tamping rod 33 is provided with an arcuate slot; the tamping rod 11 is disposed within the arcuate slot. The distal end of the tamping rod 11 is rotatably disposed within the arcuate slot of the tamping rod rotation axis 10.

[0075] Optionally, the smoothing module includes: a bracket, a scraper 37 and a roller 38; the bracket is set at the outlet of the conveying module 41; the concrete mixture in the forming mold 40 is smoothed by the scraper 37 and the roller 38 of the smoothing module.

[0076] In an exemplary embodiment, the performance parameters include slump value, and the start and stop of the vibration module and the tamping module are controlled according to the performance parameters of the concrete mixture, specifically including:

[0077] When the slump value is below the preset threshold, the vibration module is controlled to start running and the tamping module is stopped;

[0078] When the slump value is greater than the preset threshold, the vibration module is controlled to stop running and the tamping module starts running.

[0079] When the concrete slump value is less than or equal to the preset threshold, the material is discharged from the discharge port all at once. When the concrete flow meter 30 detects that the outflow of the concrete mixture is equal to the volume of the forming mold 40, the discharge port is closed. The vibration spring 35 begins to vibrate. After a certain period of time, the conveying roller 34 conveys the forming mold 40 to the scraper 37 and roller 38 for scraping and plastering, and then the conveyor belt conveys it to a specific location for curing.

[0080] When the slump value of concrete is greater than the preset threshold value, the discharge port discharges the concrete in two times. When the flow meter at the discharge port monitors that the concrete outflow is equal to 1 / 2 of the volume of the forming mold 40, the telescopic pneumatic pump 32 is extended and retracted up and down and rotated from outside to inside to perform tamping for 20 seconds. After the tamping is completed, the rotatable tamping rod 33 is lifted to 1 / 2 of the height value of the forming mold 40 to continue discharging the concrete. When the flow meter at the discharge port monitors that the concrete outflow is equal to the volume of the forming mold 40, the discharge port is closed. The rotatable tamping rod 33 is continued to tamping for 20 seconds. After the tamping is completed, the rotatable tamping rod 33 is lifted to the highest position. The roller 38 and the conveyor belt transport the forming mold 40, which is smoothed by the scraper 37 and the roller 34 and finally transported to the set position.

[0081] Furthermore, a diversion trough 39 is provided under the forming unit for diverting waste slurry of the concrete mixture.

[0082] The concrete specimen forming device of this embodiment controls the start and stop of the vibration module and the tamping module according to the performance parameters of the concrete mixture after the concrete mixture is placed in the forming mold 40, thereby realizing the preparation of the concrete specimen.
