[0022] The specific implementation of the present invention is described in detail below with reference to the accompanying drawings:

[0023] In the present invention, the directional words used, such as "up, down, left, right", generally refer to the up, down, left, right shown in the reference drawings; "longitudinal, transverse" refer to the moving directions of the two slide modules of the bag cutting device in the bag breaking system, among which "longitudinal" refers to the moving direction of the rack slide module, and "transverse" refers to the moving direction of the screw slide module.

[0024] See also Figure 1 The automatic bag unpacking machine for forage packaging comprises a roller conveyor 2, a bag pushing mechanism 3, a dust removal system 4, a bag grabbing mechanism 5, a bag breaking mechanism 6, a material discharge door mechanism 7, a material discharge adjustment mechanism 8, and a frame 9; a roller conveyor 2 is arranged above the frame 9, a conveyor belt 1 is arranged on one side of the roller conveyor 2, and a material bag 10 is conveyed to the bag pushing mechanism 3 by the conveyor belt 1 and the roller conveyor 2; the bag pushing mechanism 3 sends the material bag 10 to the material discharge door mechanism 7; the bag grabbing mechanism 5 fixes the material bag 10, and then the bag is broken by the bag breaking mechanism 6; the material discharge door mechanism 7 sends the forage separated from the bag due to gravity to the forage outlet through the material discharge adjustment mechanism 8;

[0025] See also Figure 2-Figure 4 , Figure 7 , the first cylinder 32 of the bag pushing mechanism 3 is controlled by the solenoid valve of the bag pushing mechanism 3 to drive the push plate 31 to push the material bag 10 to the left, and the material bag 10 is pushed to the discharge door 71, and the second cylinder 51 of the bag grabbing mechanism 5 is controlled by the solenoid valve of the bag grabbing mechanism 5 to push the connecting rod mechanism 52 to the left, and at the same time, the connecting rod mechanism 52 drives the four bag grabbing hooks 53 to rotate counterclockwise, and the four bag grabbing hooks 53 hook the material bag 10. When the grass falls off and the discharge door 71 is reset, the second cylinder 51 of the bag grabbing mechanism 5 is controlled by the solenoid valve of the bag grabbing mechanism 5 to pull the connecting rod mechanism 52 to the right, and at the same time, the connecting rod mechanism 52 drives the four bag grabbing hooks 53 to rotate clockwise, and the four bag grabbing hooks 53 release the broken bag.

[0026] See also Figure 5 , Figure 6 After the bag grabbing mechanism 5 fixes the material bag 10, the saw blade motor 66, the rack slide module motor 64 and the screw slide module motor 63 are controlled to operate, and the bag cutting device is driven by the moving device to move a U-shaped route, cutting the bag of the material bag along three directions in the horizontal plane, so that the material bag is broken and can fall down completely.

[0027] See also Figure 1 , Figure 4 , Figure 7 , the third cylinder 72 of the discharge door mechanism is controlled to retract through the electromagnetic valve of the discharge door mechanism 7, driving the discharge door 71 to turn down 90 degrees counterclockwise. The broken grass bag falls to the grass outlet through the feed adjustment mechanism 8 under the action of gravity, and the broken bag is hooked by the bag grabbing hook of the bag grabbing mechanism 5. After all the grass has fallen, the third cylinder 72 of the discharge door mechanism is controlled to extend through the electromagnetic valve of the discharge door mechanism, driving the discharge door 71 to turn up 90 degrees clockwise.

[0028] The air compressor 11 is responsible for the moving power of the three cylinders in the bag pushing mechanism 3, the bag grabbing mechanism 5 and the discharge door mechanism 7;

[0029] The saw blade motor 66 is responsible for the rotational power of the saw blade;

[0030] The rack slide module motor 62 is responsible for the longitudinal movement capability of the bag cutting device in the bag breaking mechanism 6;

[0031] The screw slide module motor 63 is responsible for the lateral movement capability of the bag cutting device in the bag breaking mechanism 6;

[0032] Specifically, the material bag 10 is conveyed to the bag pushing mechanism 3 by the conveyor belt 1 and the roller conveyor 2. The push plate 32 pushes the material bag 10 to the discharge gate 71 under the action of the first cylinder 32 in the bag pushing mechanism 3. The second cylinder 51 in the bag grabbing mechanism 5 pushes to the left, so that the connecting rod mechanism 52 moves, and the four bag grabbing hooks 53 rotate counterclockwise to hook the material bag 10. The bag breaking mechanism 6 is driven by the moving device to move the bag cutting device in a U-shaped route, and the bag of the material bag is cut in three directions in the horizontal plane. The discharge gate mechanism 7 discharges the material door 71 counterclockwise by 90 degrees under the action of the third cylinder 72 of the discharge gate mechanism 7. The broken material bag falls under the action of gravity through the material discharge adjustment mechanism 8 and falls to the material outlet, and the broken bag is hooked by the bag grabbing hook of the bag grabbing mechanism 5. After all the forage has fallen, the discharge gate 71 turns up 90 degrees clockwise under the action of the third cylinder 72 of the discharge gate mechanism 7. The piston rod of the second cylinder 51 in the bag grabbing mechanism 5 retracts to the right, causing the connecting rod mechanism 52 to move, and the four bag grabbing hooks 53 rotate clockwise, so that the broken bag breaks away from the bag grabbing hooks 53 and falls on the discharge gate 71. When the next bag of material is pushed onto the discharge gate 71, the broken bag is pushed to the bag outlet.

[0033] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
