DETAILED DESCRIPTION

[0018] The following will be combined with the drawings Figs. 1 to 4This utility model will be described in detail.

[0019] This utility model discloses a highly safe mixing tank discharge structure, comprising a material tank 1 that can be assembled into a mixer. The bottom of the material tank 1 is provided with a downwardly extending first discharge channel 2. The side wall of the first discharge channel 2 is provided with several discharge pipes 21, which extend outwards and differ in height and direction. A first piston 3 is disposed within the first discharge channel 2. A second discharge channel 31 is disposed in the middle of the first piston 3. A guide port 32 is disposed on the side wall of the second discharge channel 31. A second piston 33 is disposed within the second discharge channel 31. One end of the second piston 33... A cylinder 34 is provided, which is fixedly connected to the first piston 3. The cylinder 34 can drive the second piston 33 to move within the second discharge channel 31, causing the guide port 32 to open or close. Specifically, when the cylinder 34 drives the second piston 33 to push upward, the second piston 33 will block the second discharge channel 31 from the guide port 32, and the guide port 32 will be closed, preventing material from entering the guide port 32. Conversely, when the second piston 33 retracts downward, the second discharge channel 31 and the guide port 32 are interconnected, and the guide port 32 turns into an open state, allowing material entering the second discharge channel 31 to enter the guide port 32. The bottom of the material barrel 1 is also provided with a guide post 22, a connecting plate 4 movably connected to the guide post 22, and a first driving device 41 that drives the connecting plate 4 to rise and fall. The connecting plate 4 is movably connected to the first piston 3, and the second driving device 42 is provided on the connecting plate 4. The second driving device 42 can drive the first piston 3 to rotate, allowing the guide port 32 to communicate with the discharge pipe 21. The first driving device 41 drives the first piston 3 to move up and down within the first discharge channel 2, thereby controlling the height of the guide port 32. The second driving device 42 drives the first piston 3 to rotate, thereby controlling the direction of the guide port 32, allowing the material to enter the designated discharge pipe 21 through the guide port 32 for precise discharge. More specifically, the first driving device 41 drives the first piston 3 to sink, making the guide port 32 the same height as the discharge pipe 21 to be discharged. Then, the second driving device 42 drives the first piston 3 to rotate, making the guide port 32 interconnected with the discharge pipe 21 to be discharged. During this process, the material in the hopper 1 enters the first discharge channel 2. Afterward, the cylinder 34 drives the second piston 33 to sink, allowing the material to enter the second discharge channel 31 from the first discharge channel 2, and finally exit through the discharge pipe 21. This utility model solution can switch each discharge pipe 21 through a mechanical transmission structure, eliminating the need for personnel to approach the mixing equipment for operation, thus ensuring high safety.

[0020] One end of the first piston 3 is provided with an extension rod 35, and the end of the extension rod 35 is provided with a rotating block 36. The cylinder 34 is connected to the rotating block 36. In this solution, the cylinder 34 and the rotating block 36 are movably connected. When the rotating block 36 rotates, the cylinder 34 can remain stationary, avoiding damage to the air pipe connected to the cylinder 34.

[0021] The upper and lower sides of the rotating block 36 are provided with limiting sheets 37, the two limiting sheets 37 and the rotating block 36 cooperate to form an annular groove 38, and the connecting plate 4 is clamped with the annular groove 38. The connecting plate 4 cooperates with the guide column 22, so that the connecting plate 4 can only move along the guide column 22 and cannot rotate with the rotating block 36. The side surface of the connecting plate 4 facing the rotating block 36 is in a concave arc shape, so that the connecting plate 4 can be stably clamped with the annular groove 38. In this structure, when the connecting plate 4 moves up and down, the rotating block 36 is also displaced, and then when the rotating block 36 rotates, the connecting plate 4 is fixed.

[0022] The second driving device 42 is provided with a motor a421, the end of the rotor of the motor a421 is provided with a power gear 422, and the rotating block 36 is provided with a transmission gear 39 matched with the power gear 422. The motor a421 is fixedly installed on the connecting plate 4, the motor a421 drives the power gear 422 to rotate, so that the rotating block 36 rotates, and then the first piston 3 rotates. Since the connecting plate 4 is clamped with the annular groove 38 of the rotating block 36, the relative positions of the power gear 422 and the transmission gear 39 are consistent, and the stability is high.

[0023] The connecting plate 4 is provided with a threaded sleeve 43, the first driving device 41 is provided with a motor b411 and a power screw 412 threadedly connected with the threaded sleeve 43. The motor b411 drives the power screw 412 to rotate, so that the connecting plate 4 moves along the guide column 22. The connection between the power screw 412 and the threaded sleeve 43 converts the rotary motion into linear motion, and has the characteristics of large power and high precision.

[0024] A shaft coupling 413 is arranged between the power screw 412 and the motor b411. One side of the shaft coupling 413 is connected with the end of the power screw 412, and the other side of the shaft coupling 413 is connected with the end of the rotor of the motor b411. When different models of power screws 412 need to be replaced, only the specific model of the shaft coupling 413 needs to be replaced.

[0025] The second discharge channel 31 is provided with an expanded portion 311 at the port. The expanded portion 311 can expand the range of the second discharge channel 31 to access the material, and reduce the residual amount of the material in the first discharge channel 2.

[0026] The above is only a preferred embodiment of the present application. For those skilled in the art, according to the idea of the present application, the specific implementation and application range can be changed, and the content of the specification should not be understood as a limitation of the present application.
