[0013] Compared with related technologies, the movable discharge port for the mixing plant provided by this utility model has the following beneficial effects:

[0014] This utility model provides a movable discharge port for a mixing plant. When using the torpedo tank to transport concrete, the torpedo tank moves along the first guide rail, and the inlet of the torpedo tank is aligned with the discharge port of the mixing plant, allowing concrete to enter the interior of the torpedo tank through the discharge port. When using a concrete truck to transport concrete, the DC motor is turned on, driving the second gear to rotate. The second gear drives the first gear and the rotating shaft to rotate.

The diameter of the second gear is smaller than the diameter of the first gear, allowing the second gear to drive the... The first gear rotates with less effort, making it easier for the DC motor to drive the feeding hopper along the second guide rail. The second guide rail consists of an ascending section and a stable section. The feeding hopper enters the ascending section along the stable section, causing it to move upwards. As the feeding hopper moves upwards into the stable section, it continues to move smoothly forward and align with the discharge port of the mixing plant. The concrete truck moves to align its inlet with the conveying hose.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1 to 6 , Figure 1 A schematic diagram of a preferred embodiment of the movable discharge port for a mixing plant provided by this utility model; Figure 2 for Figure 1 The side view of the unloading platform structure shown; Figure 3 for Figure 1 The diagram shows the internal structure of the feeding hopper. Figure 4 for Figure 3 The diagram shows a top view of the internal structure of the box. Figure 5 for Figure 1 The top view of the second guide rail structure shown; Figure 6 for Figure 5 The diagram shows the internal structure of the first fixed rod. A movable discharge port for a mixing plant includes a discharge platform 1. A discharge port 11 is installed on the surface of the discharge platform 1, and a first guide rail 31 is installed at the bottom end of the discharge platform 1. A torpedo tank 3 is slidably connected inside the first guide rail 31. When using the torpedo tank 3 to transport concrete, the torpedo tank 3 moves along the first guide rail 31, aligning its inlet with the discharge port 11 of the mixing plant, allowing concrete to enter the interior of the torpedo tank 3 through the discharge port 11, thus enabling the torpedo tank 3 to transport concrete.

[0024] The bottom of the unloading platform 1 is provided with a second guide rail 5, which consists of an ascending section 52 and a stable section 53. Both ends of the ascending section 52 are connected to the stable section 53. The second guide rail 5 is internally connected to a support mechanism 6, a guide mechanism 7, and a drive mechanism 8. The side wall of the unloading funnel 4 is fixedly connected to the support mechanism 6, the guide mechanism 7, and the drive mechanism 8. The drive mechanism 8 includes a housing 83. The side wall of the unloading funnel 4 is symmetrically fixedly connected to the housing 83. A DC motor 85 is installed inside the housing 83. The output shaft of the DC motor 85 is connected to a second gear 86. The side wall of the housing 83 is rotatably connected to a rotating shaft 84. Both ends of the rotating shaft 84 are fixedly connected to a first gear 81. A toothed plate 82 is installed on the surface of the second guide rail 5. One of the first gears 81 meshes with the toothed plate 82, and the other first gear 81 meshes with the second gear 86. The diameter of the second gear 86 is smaller than the diameter of the first gear 81. When concrete is transported using concrete truck 2, the DC motor 85 is turned on. The DC motor 85 drives the second gear 86 to rotate, and the second gear 86 drives the first gear 81 and the rotating shaft 84 to rotate. The first gear 86 moves along the gear plate 82, causing the feed hopper 4 to move along the second guide rail 5 towards the discharge port 11 of the mixing plant. The diameter of the second gear 81 is smaller than the diameter of the first gear 86, making it easier for the second gear 81 to drive the first gear 86 to rotate, thus facilitating the DC motor 85 to push the feed hopper 4 along the second guide rail 5. The second guide rail 5 moves, consisting of an ascending section 52 and a stable section 53. The feeding hopper 4 enters the ascending section 52 along the stable section 53, causing the feeding hopper 4 to move upward and increase its height. As the feeding hopper 4 moves upward and enters the stable section 53, it continues to move smoothly forward and align with the discharge port 11 of the mixing plant. The concrete transport vehicle 2 moves so that its inlet aligns with the conveying hose 41. Concrete enters the interior of the concrete transport vehicle 2 through the discharge port 11 of the mixing plant, the feeding hopper 4, and the conveying hose 11, preventing concrete from scattering.

[0025] The support mechanism 6 includes a support shaft 61. Multiple support shafts 61 are installed on the side wall of the feeding hopper 4. One end of each support shaft 61 is rotatably connected to a support roller 62. The top surface of the second guide rail 5 is provided with a groove 63, and the support roller 62 is slidably connected inside the groove 63. When the feeding hopper 4 moves along the second guide rail 5, it drives the support shaft 61 and the support roller 62 to move. The support roller 62 moves along the groove 63. The support roller 62 and the support shaft 61 provide upward support for the feeding hopper 4. At the same time, the groove 63 limits the position of the support roller 62, thereby limiting the position of the feeding hopper 4 and preventing it from shifting during movement.

[0026] The support shaft 61 and the rotating shaft 84 are symmetrically fixed at the center position of the feeding funnel 4, and the center of the support shaft 61, the rotating shaft 84, the support roller 62, the first gear 81, and the feeding funnel 4 are located in the same plane. In order to keep the center of gravity of the feeding funnel 4 from shifting during the movement, the feeding funnel 4 tilts as a whole during the movement.

[0027] The bottom of the discharge funnel 4 is equipped with a discharge hose 41. The total height of the discharge funnel 4 and the discharge hose 41 is about 4 meters. The discharge hose 41 reduces the overall weight of the discharge funnel 4 and delivers concrete to the concrete transport vehicle 2 through the discharge funnel 4 and the discharge hose 41, thus preventing the concrete from scattering.

[0028] The guiding mechanism 7 includes a first fixing rod 71. Multiple first fixing rods 71 ​​are obliquely installed on the side wall of the feeding funnel 4. A second fixing rod 72 and a piston 75 are slidably connected inside the first fixing rod 71. The piston 75 is installed at the top of the second fixing rod 72. A spring 77 is installed inside the first fixing rod 71, and the bottom end of the spring 77 is connected to the top surface of the piston 75. A clamping plate 73 is fixedly connected to the bottom end of the second fixing rod 72. A roller 74 is fixedly connected inside the clamping plate 73, and the roller 74 is slidably connected to the inside of the slot 63. A sealing ring 78 is installed at the bottom end of the first fixing rod 71, and the second fixing rod 72 is slidably connected inside the sealing ring 78. A limiting block 76 is installed on the inner side wall of the first fixing rod 71, and the limiting block 76 abuts against the top surface of the piston 75. When the feeding funnel 4 moves along the direction of the second guide rail 5, the feeding funnel 4 drives the first fixing rod 71, the second fixing rod 72, the clamping plate 73, and the roller 74 to move. The roller 74 moves along the slot 63, and the guide mechanism 7 fixes the feeding funnel 4 from multiple angles, increasing the stability of the feeding funnel 4's movement. When the height of the second guide rail 5 changes, the spring 77 extends and retracts to push the piston 75 and the second fixing rod 72 to move, so that the clamping plate 73 always moves along the slot 63, and the spring 77, which is always in a compressed state, pushes the first fixing rod 71 and the second fixing rod 72 upward to hold the feeding funnel 4, increasing the stability of the feeding funnel 4's movement. When the feeding funnel 4 tilts, the feeding funnel 4 pushes the piston 75 on one side to move and abut against the limiting block 76. The limiting block 76 blocks the piston 75 and the second fixing rod 72 from continuing to move, thereby preventing the feeding funnel 4 from tilting too much. The movement of the piston 75 also compresses the air inside the first fixing rod 71, and the compressed air increases the resistance to the movement of the piston 75, preventing the piston 75 from moving too much.

[0029] The second guide rail 5 is vertically located below the first guide rail 31. In order to avoid the second guide rail 5 affecting the operation of the torpedo canister 3, the double-layered second guide rail 5 is fixed to the side wall of the feeding platform 1 by the support frame 51. The double-layered second guide rail 5 increases the stability of the movement of the feeding funnel 4.

[0030] The working principle of the movable discharge port for the mixing plant provided by this utility model is as follows: when the device is connected to an external power source and the torpedo tank 3 is used to transport concrete, the torpedo tank 3 moves along the first guide rail 31 and the inlet of the torpedo tank 3 is aligned with the discharge port 11 of the mixing plant, so that the concrete enters the interior of the torpedo tank 3 through the discharge port 11 of the mixing plant, and the torpedo tank 3 transports the concrete. When concrete is transported using the concrete truck 2, the DC motor 85 is turned on, which drives the second gear 86 to rotate. The second gear 86 drives the first gear 81 and the rotating shaft 84 to rotate. The first gear 86 moves along the toothed plate 82, causing the feeding hopper 4 to move along the second guide rail 5 towards the discharge port 11 of the mixing plant. The diameter of the second gear 81 is smaller than that of the first gear 86, making it easier for the second gear 81 to drive the first gear 86 to rotate. This facilitates the DC motor 85 in pushing the feeding hopper 4 along the second guide rail 5. The discharging hopper 4 drives the support shaft 61 and the support roller 62 to move. The support roller 62 moves along the slot 63. The support roller 62 and the support shaft 61 provide upward support for the discharging hopper 4, while the slot 63 limits the support roller 62, thereby limiting the position of the discharging hopper 4 and preventing it from shifting during movement. Furthermore, when the feeding hopper 4 moves along the direction of the second guide rail 5, the feeding hopper 4 drives the first fixing rod 71, the second fixing rod 72, the clamping plate 73 and the roller 74 to move. The roller 74 moves along the slot 63. The guiding mechanism 7 fixes the feeding hopper 4 from multiple angles, increasing the stability of the movement of the feeding hopper 4. The second guide rail 5 consists of an ascending section 52 and a stable section 53. The feeding hopper 4 enters the ascending section 52 along the stable section 53, causing the feeding hopper 4 to move upward and increase its height. When the height of the second guide rail 5 changes, the spring 77 extends and retracts, pushing the piston 75 and the second fixing rod 72 to move, so that the clamping plate 73 always moves along the slot 63. The spring 77, which is always in a compressed state, pushes the first fixing rod 71 and the second fixing rod 72 upward to hold the discharging hopper 4, increasing the stability of the discharging hopper 4's upward movement. As the feeding hopper 5 moves upward and enters the stable section 53, the height of the feeding hopper 4 is increased and it continues to move forward smoothly to align with the mixing plant's discharge port 11. The concrete transport vehicle 2 moves so that its inlet aligns with the conveying hose 41. The concrete enters the interior of the concrete transport vehicle 2 through the mixing plant's discharge port 11, the discharging hopper 4, and the conveying hose 11, preventing the concrete from scattering. After use, turn on the DC motor 85 to reverse the DC motor 85 and push the lower funnel 4 downward to reset.
