The discharge end of the receiving hopper 4 is provided with multiple equally spaced square distributing channels 5. The bottom of the receiving hopper 4 slides in contact with the upper part of the test block mold assembly. The test block mold assembly is provided with multiple rows of test block mold cavities 6 arranged corresponding to the square distributing channels 5. Furthermore, the horizontal feed drive 2 is preferably an electric cylinder, but other equivalent components such as a mechanical slide table that can drive the test block mold assembly to feed can also be used; the cross-sectional dimensions of the test block mold cavity 6 are the same as the cross-sectional dimensions of the corresponding square material distribution channel 5, and the test block mold cavity 6 can be a cubic mold cavity with standard dimensions such as 100cm*100cm*100cm, 150cm*150cm*150cm and 200cm*200cm*200cm; it should be noted that when the discharge height of the concrete mixing tank is high, the pusher trolley 1 can be a pusher trolley with a scissor lift platform so that the concrete material discharged from the mixing tank can fall smoothly into the receiving hopper 4.

[0029] For details, please refer to Figures 1-4 A slide 21 is installed on the pusher trolley 1, and the test block mold box assembly is slidably installed on the slide 21.

[0030] For details, please refer to Figures 3-4 The bottom of the test block mold assembly is equipped with a first vibration motor 7, and an elastic connector 8 is provided between the horizontal feed driver 2 and the test block mold assembly. The horizontal feed driver 2 and the test block mold assembly are elastically connected through the elastic connector 8.

[0031] For details, please refer to Figure 5 The elastic connector 8 includes a telescopic rod and a second spring sleeved on the extended end of the telescopic rod. One end of the telescopic rod is fixedly connected to the output end of the horizontal feed driver 2, and the other end of the telescopic rod is fixedly connected to the test block mold assembly.

The lifting frame 10 and the slide plate 11 are elastically connected by multiple first springs 14. Furthermore, the bottom of the vibrating rod 12 can extend into the test block mold cavity 6.

[0036] Specifically, there are at least four sets of vibration rods 12 located in one of the test block mold cavities 6, and the four sets of vibration rods 12 can extend into the inner corners of the test block mold cavity 6 respectively; furthermore, the four sets of vibration rods 12 are evenly distributed in the test block mold cavity 6.

[0038] The sampling mechanism of the concrete mixing tank provided in this embodiment, when receiving concrete material discharged from the mixing tank, has the vibrating rod 12 located at the upper part of the receiving hopper 4. The second vibrating motor 13 starts and drives the sliding plate 11 to vibrate up and down. Under the action of the first spring 14, the vibrating rod 12 follows the sliding plate 11 to vibrate up and down. Under the vibration of the vibrating rod 12, the smoothness of the concrete material flowing into the square material distribution channel 5 can be improved.

[0041] The sampling mechanism of the concrete mixing tank provided in this embodiment can open each of the surrounding plates 17 around the hinge to the outside of the bottom plate 16 after the concrete in the test block mold cavity 6 has solidified. The transverse partitions 18 and longitudinal partitions 19 can be gradually removed from the outside to the inside, which makes it easier to unload the formed concrete test blocks and improves the convenience of unloading the formed concrete test blocks.

[0042] The sampling mechanism of the concrete mixing tank provided by this utility model is used as follows: The pusher trolley 1 is pushed to the discharge port of the concrete mixing tank. The receiving hopper 4 is located below the discharge port of the concrete mixing tank. The concrete material falls into the receiving hopper 4. After preliminary vibration by the lifting and vibrating assembly, the concrete material falls into the corresponding test block mold cavity 6. The horizontal feed driver 2 drives the test block mold assembly to feed. The next row of test block mold cavities 6 moves to below the square material distribution channel 5. The bottom of the receiving hopper 4 can accommodate the concrete material. The top of the test block mold cavity 6 is smoothed, the first vibration motor 7 is started, and under the action of the elastic connector 8, the test block mold box assembly vibrates in the horizontal direction.
