[0036] A silo mechanism 1, the silo mechanism 1 comprises a discharge silo 11, a butterfly valve 12 is installed at the discharge port of the discharge silo 11, and a docking assembly 13 is installed below the butterfly valve 12;

[0037] A moving mechanism 2, the moving mechanism 2 is used to move the silo mechanism 1, the moving mechanism 2 is provided with a discharge station, and the discharge station is provided with a docking through hole 21 connected with the docking assembly 13;

[0038] A pneumatic conveying mechanism 3, wherein the pneumatic conveying mechanism 3 is located below the unloading station, and the pneumatic conveying mechanism 3 automatically docks with the docking assembly 13 when the silo mechanism 1 reaches the unloading station;

[0039] The valve opening mechanism 4 is used to drive the butterfly valve 12 to open when the silo mechanism 1 reaches the unloading position, so that the discharge port of the unloading silo 11 is connected to the pneumatic conveying mechanism 3.

[0040] In the present invention, the mobile mechanism 2 moves the silo mechanism 1 to the unloading position. When the silo mechanism 1 reaches the unloading position, the pneumatic conveying mechanism 3 automatically docks with the docking assembly 13 of the silo mechanism 1, and then the butterfly valve 12 of the silo mechanism 1 is opened by the valve opening mechanism 4. After the butterfly valve 12 is opened, the pneumatic conveying mechanism 3 starts to work to suck away all the materials in the unloading silo 11. After the unloading is completed, the pneumatic conveying mechanism 3 is separated from the silo mechanism 1, and the mobile mechanism 2 transports the silo mechanism 1 to the starting position. Through the cooperation among the moving mechanism 2, the valve opening mechanism 4 and the pneumatic conveying mechanism 3, the silo mechanism 1 can be fully automatically unloaded at a fixed point, and the pneumatic conveying mechanism 3 can directly convey the material to the back-end equipment at a fixed point and in a fixed quantity, so that the whole process is automated. There is no need to manually move the silo mechanism 1 with prepared materials to a fixed unloading station and then pour it into a designated unloading station, and then move the silo mechanism 1 back to the conveyor line, which saves a lot of links and does not require manual participation in the whole process, thus reducing labor costs. There is no dust spillage, and the operation is safe and environmentally friendly with a high degree of automation.

[0041] As a preferred embodiment, it also includes a jacking mechanism 5, which includes a jacking pipe 51, a jacking plate 54 connected to the jacking pipe 51, a cloth bag 52 and a jacking drive 53. The top end of the jacking pipe 51 is used to dock with the docking assembly 13, the jacking pipe 51 is connected to the pneumatic conveying mechanism 3 through the cloth bag 52, and the jacking drive 53 is connected to the jacking plate 54.

[0042] In this embodiment, when the silo mechanism 1 reaches the unloading station, the lifting drive 53 drives the lifting plate 54 to move in the direction of the upper silo mechanism 1, and then the lifting pipe 51 is docked with the docking assembly 13, so that the pneumatic conveying mechanism 3 and the silo mechanism 1 are automatically docked. In addition, the lifting pipe 51 is connected to the pneumatic conveying mechanism 3 through the bag 52, so that dust can be prevented from overflowing. Preferably, the lifting drive 53 is a lifting cylinder.

[0043] As a preferred embodiment, a blocking mechanism 6 is further included, and the blocking mechanism 6 is used to block the movement of the silo mechanism 1 when the silo mechanism 1 reaches the unloading position. When the silo mechanism 1 reaches the unloading position, the blocking mechanism 6 blocks the silo mechanism 1 from continuing to move, so that the silo mechanism 1 is positioned at the unloading position, which is convenient for the pneumatic conveying mechanism 3 to dock with it.

[0044] As a preferred embodiment, the blocking mechanism 6 includes a blocking bracket 61, a blocking member 62 disposed on the blocking bracket 61, and a blocking driving member 63 driving the blocking member 62 to move, and the movement direction of the blocking member 62 is perpendicular to the movement direction of the silo mechanism 1. Preferably, the blocking driving member 63 is a blocking cylinder.

[0045] As a preferred embodiment, it also includes a photoelectric sensing mechanism 9, which is used to sense the arrival signal of the silo mechanism 1 at the unloading position and send the arrival signal to the limit drive, and the limit drive receives the arrival signal and controls the extension of the blocking member 62 to lock the silo mechanism 1 at the unloading position. By setting the photoelectric sensing mechanism 9, the blocking mechanism 6 can block the silo mechanism 1 in time, so that the silo mechanism 1 is accurately positioned at the unloading position.

[0046] As a preferred embodiment, a limiting mechanism 7 is further included. The limiting mechanisms 7 are provided on both the left and right sides of the mobile mechanism 2. The limiting mechanisms 7 are used to limit the left and right positions of the silo mechanism 1 to the unloading position. In this embodiment, the silo mechanism 1 can be accurately positioned at the unloading position through the cooperation between the blocking mechanism 6 and the limiting mechanism 7. Preferably, the limiting mechanism 7 includes a limiting rod 71 and a limiting cylinder 72 for driving the limiting rod 71 to move. The length direction of the limiting rod 71 is consistent with the conveying direction of the mobile mechanism 2, and the moving direction of the limiting rod 71 is perpendicular to the conveying direction of the mobile mechanism 2.

[0047] As a preferred embodiment, a vibration mechanism 8 is also included, and the vibration mechanism 8 includes a vibration bracket 81 and a vibrator 82 arranged on the vibration bracket 81. The top of the vibration bracket 81 is provided with a pressing part 83 for pressing the silo mechanism 1. In this embodiment, after the jacking mechanism 5 is docked with the docking assembly 13, the jacking drive 53 drives the jacking plate 54 to continue to rise, so that the silo mechanism 1 is separated from the moving mechanism 2. When the upper part of the silo mechanism 1 contacts the pressing part 83, the jacking drive 53 stops working. At this time, the valve opening mechanism 4 is also aligned with the butterfly valve 12. After the valve opening mechanism 4 opens the butterfly valve 12, the pneumatic conveying mechanism 3 and the vibrator 82 start working at the same time. Under the action of the vibrator 82, the material adhered to the inner wall of the discharge bin 11 is vibrated down, so that there is no residual material in the discharge bin 11. In addition, the setting of the vibration mechanism 8 allows the material in the discharge bin 11 to be discharged faster and better. Preferably, the vibrator 82 is a vibration motor.

[0048] As a preferred embodiment, the valve opening mechanism 4 includes a translation rodless cylinder 41, a rotating assembly connected to the cylinder body of the translation rodless cylinder 41, and the rotating assembly includes a grab bar 42 for grabbing the butterfly valve 12, and a rotating cylinder 43 for driving the grab bar 42 to rotate, and the grab bar 42 is connected to the piston moving part of the rotating cylinder 43. When the silo mechanism 1 reaches the unloading station, the translation rodless cylinder 41 drives the rotating assembly to move toward the butterfly valve 12. When the grab bar 42 is inserted into the butterfly valve 12, the rotating cylinder 43 drives the grab bar 42 to rotate, and then opens the butterfly valve 12, so that the unloading silo 11 is connected to the pneumatic conveying mechanism 3.

[0049] As a preferred embodiment, the valve opening mechanism 4 further includes a guide rod 44 and a slider 45 slidably disposed on the guide rod 44, and the rotating assembly further includes a connecting plate 46, and the slider 45 and the cylinder body of the translation rodless cylinder 41 are both connected to the connecting plate 46. By providing the guide rod 44, the movement of the rotating assembly is guided, so that the grab bar 42 can be accurately docked with the butterfly valve 12.

[0050] As a preferred embodiment, the pneumatic conveying mechanism 3 includes a pneumatic conveying pipe 31 connected to the cloth bag 52 and a pneumatic conveying pump 32 connected to the pneumatic conveying pipe 31. The pneumatic conveying pump 32 can realize continuous conveying of materials, thereby improving conveying efficiency, reducing wear of conveying pipes, improving production efficiency, and reducing time costs; at the same time, it can save equipment manufacturing costs, reduce the floor space occupied by equipment, and play a role in energy saving and consumption reduction.

[0051] The unloading process of the silo mechanism 1 of the present invention is as follows: after the mobile mechanism 2 has finished distributing the materials, the silo mechanism 1 will be moved to the unloading station by the mobile mechanism 2; before the silo mechanism 1 arrives at the unloading station, the limiting mechanism 7 will limit the silo mechanism 1 left and right to introduce it into the unloading station area; the photoelectric sensing mechanism 9 on the unloading station senses the signal from the silo, and the blocking mechanism 6 will immediately push out the blocking member 62 after receiving the signal, so that the silo mechanism 1 cannot move forward and stops in place; at this time, the lifting mechanism 5 lifts the silo mechanism 1 as a whole and separates it from the mobile mechanism 2; the lifting height is set to the same height as the valve opening mechanism 4, and the limiting size of the vibration mechanism 8 is also equivalent to this height; the silo mechanism 1 is lifted up The rear vibration mechanism 8 can press the silo mechanism 1 tightly. At this time, the translational rodless cylinder 41 of the valve opening mechanism 4 pushes the grab rod 42 to the rotating shaft of the butterfly valve 12 of the silo mechanism 1. After the grab rod 42 is docked with the butterfly valve 12, the rotating cylinder 43 works to open the butterfly valve 12, and the vibration mechanism 8 starts to work. After the butterfly valve 12 is opened, the pneumatic conveying mechanism 3 below starts to work to suck away all the materials in the unloading bin 11. After the materials are unloaded, the vibration mechanism 8 stops, the rotating cylinder 43 of the valve opening mechanism 4 is reset, the butterfly valve 12 is closed, the translational rodless cylinder 41 is reset, the grab rod 42 returns to its position, the lifting mechanism 5 returns to its position, and then the blocking mechanism 6 returns to its position, and the silo mechanism 1 continues to move forward, and a reciprocating unloading process is carried out through a circulating loop.
