[0044] This embodiment 1 provides an automatic material distribution device for concrete sampling, as part of the concrete mixture sampling and molding automation equipment, for automatically distributing concrete into a concrete mold when sampling the concrete mixture, which can realize the intelligentization of concrete sampling and molding. As shown in Figures 1-3 It comprises:

[0045] Steel frame 10, specifically, the steel frame 10 is a square structure, which can be formed into a stable support by connecting four strip steels to form a stable support, so as to bear the weight of the material distribution mechanism 30 and the opening and closing mechanism 40.

[0046] Material distribution mechanism 30, installed on the steel frame 10;

[0047] Discharging mechanism 20, arranged on the top of the material distribution mechanism 30 and communicated with the material distribution mechanism 30, for receiving the sampling concrete;

[0048] The opening and closing mechanism 40 is installed on the steel frame 10 and connected with the cloth mechanism 30 to automatically open or close the bottom opening of the cloth mechanism 30.

[0049] The specific working process is as follows: when the automatic cloth device for sampling concrete is used, the produced concrete falls into the discharging mechanism 20, and then falls into the cloth mechanism 30 through the stirring of the discharging mechanism 20. Through the control of the opening and closing mechanism 40, the concrete in the cloth mechanism 30 automatically falls into the concrete mold below, thereby completing the automatic cloth of the sampled concrete.

[0050] Further, the discharging mechanism 20 and the cloth mechanism 30 are connected by bolt fixing. Specifically, the bottom outer side of the discharging mechanism 20 is provided with a mounting frame matching the size of the discharging hopper 21, and the mounting frame matches the top of the cloth mechanism 30, so as to connect the discharging mechanism 20 and the cloth mechanism 30.

[0051] In order to further ensure that the discharging mechanism 20 and the cloth mechanism 30 are connected in a sealed manner, a sealing gasket 25 is connected between the discharging mechanism 20 and the cloth mechanism 30. Through the arrangement of the sealing gasket 25, the concrete is prevented from spilling during the process from the discharging mechanism 20 to the cloth mechanism 30.

[0052] Embodiment 2

[0053] Based on embodiment 1, another embodiment is provided, as shown in Figure 1 and Figure 4 The opening and closing mechanism 40 includes a gas cylinder 41, a gear set 47, a first baffle 45 and a second baffle 46,

[0054] The gas cylinder 41 is installed on one side of the steel frame 10. In this embodiment, the function of the gas cylinder 41 is to extend and retract the gas cylinder 41 to drive the movement of the first baffle 45. It can be known that the gas cylinder 41 can also be replaced by a hydraulic rod, an oil cylinder or an electric telescopic rod to achieve the same effect.

[0055] The gear set 47 includes a first gear and a second gear, and the first gear and the second gear are meshed with each other and are rotatably arranged on one side of the discharging mechanism 20. Specifically, two rotating shafts are rotatably arranged on the discharging mechanism 20, and the first gear and the second gear are respectively sleeved on the two rotating shafts, so that the rotating shafts are used to support and drive the rotation of the first gear and the second gear.

[0056] The first baffle 45 is fixedly connected with the first gear, and one side of the first baffle 45 is rotatably connected with the extension end of the gas cylinder 41. Specifically, the first baffle 45 and the second baffle 46 each include a swing arm and an arc-shaped sealing plate, the swing arm is rotatably connected with the extension end of the gas cylinder 41, and the two arc-shaped sealing plates are symmetrically arranged and located directly below the cloth mechanism 30 to close the opening.

[0057] The second baffle 46 is fixedly connected with the second gear, and the second baffle 46 moves towards or away from the first baffle 45 to open or close the bottom opening of the material distributing mechanism 30.

[0058] It can be known that, in order to adapt to the movement of the first baffle 45 and the second baffle 46, the first baffle 45 and the second baffle 46 are arranged to be arc-shaped. Figure 3 As shown, the bottom of the material distributing mechanism 30 is arc-shaped, so as to ensure the normal movement of the two arc-shaped sealing plates.

[0059] The specific working process of the opening and closing mechanism 40 is as follows:

[0060] When the material distributing mechanism 30 is opened, the air cylinder 41 is retracted, and the first baffle 45 is rotated by a certain angle in the retraction process of the air cylinder 41, so as to drive the first gear to start rotating clockwise. At the same time, under the meshing of the first gear and the second gear, the second gear starts to rotate counterclockwise to drive the second baffle 46 to rotate by a certain angle, so that the first baffle 45 and the second baffle 46 move away to open the bottom opening of the material distributing mechanism 30.

[0061] When the material distributing mechanism 30 is closed, the air cylinder 41 is extended, and the first baffle 45 is rotated by a certain angle in the retraction process of the air cylinder 41, so as to drive the first gear to start rotating counterclockwise. At the same time, under the meshing of the first gear and the second gear, the second gear starts to rotate clockwise to drive the second baffle 46 to rotate by a certain angle, so that the first baffle 45 and the second baffle 46 move towards to close the bottom opening of the material distributing mechanism 30 to return to the initial state. It can be known that, the first baffle 45 and the second baffle 46 cooperate and just adapt to the bottom opening of the material distributing mechanism 30.

[0062] Further, in order to ensure the stable rotary connection between the air cylinder 41 and the first baffle 45, a rod end bearing 42 and a bearing seat 44 are connected between the air cylinder 41 and the first baffle 45, the bearing seat 44 is fixedly connected to the first baffle 45, and the rod end is connected to the bearing seat 44 through the pin shaft 43. The arrangement of the rod end bearing 42 and the bearing seat 44 is conducive to the normal work of the opening and closing mechanism 40.

[0063] In addition, in the embodiment, two air cylinders 41 are arranged, and each air cylinder 41 is rotatably connected to the first baffle 45 through the rod end bearing 42, the pin shaft 43 and the bearing seat 44. The two air cylinders 41 are separately arranged on the two sides of the first baffle 45 to drive, so as to ensure the stability of the rotation of the first baffle 45, so that the opening and closing is more firm, and the operation is more stable.

[0064] Embodiment 3

[0065] Based on Embodiment 1 and Embodiment 2, as shown in Figure 1 and Figure 2As shown, the discharging mechanism 20 comprises a discharging hopper 21, which is in a trapezoidal structure with a wide top and a narrow bottom.

[0066] In addition, the discharging hopper 21 is also provided with a stirring mechanism for stirring and mixing the concrete in the discharging hopper 21. In use, the concrete is easy to adhere and block the communication between the discharging hopper 21 and the distributing mechanism 30. Through the stirring mechanism, on the one hand, the concrete can be scattered, and on the other hand, the speed of the concrete entering the distributing mechanism 30 is slowed down, thereby reducing the impact force of the concrete on the first baffle 45 and the second baffle 46.

[0067] In some embodiments of the technical solution, the stirring mechanism comprises a stirring shaft 22, stirring blades, and a motor 23,

[0068] The stirring shaft 22 is arranged to rotate transversely in the discharging hopper 21;

[0069] The stirring blades are arranged circumferentially outside the stirring shaft 22;

[0070] The motor 23 is installed on one side outside the discharging hopper 21, and an output shaft of the motor 23 is connected to one end of the stirring shaft 22.

[0071] A fixed bearing 24 is arranged on the side of the discharging hopper 21 away from the motor 23, and the fixed bearing 24 is connected to one end of the stirring shaft 22. Specifically, the fixed bearing 24 provides support for the rotation of the stirring shaft 22, ensuring stable rotation of the stirring shaft 22.

[0072] The working process of the stirring mechanism is as follows: start the motor 23, the motor 23 drives the stirring shaft 22 to rotate, and the stirring blades stir and scatter the concrete.

[0073] Embodiment 4
