A hooking assembly is provided on each clamping claw 23 for hooking the wrapping; the two second driving assemblies 24 are both connected to the lifting frame 21, and the power output ends of the two second driving assemblies 24 are respectively connected to the two clamping claws 23 for driving the clamping claws 23 to open and close; the feeding assembly is arranged on one side of the bag tearing assembly for conveying the silage wrapping to the lower side of the clamping claws 23; the cutting assembly is connected to the feeding assembly for cutting the lower part of the wrapping during feeding.

[0074] Specifically, the first driving assembly 22 and the second driving assembly 24 are hydraulic cylinders, electric push rods, air cylinders, etc. Preferably, both the first driving assembly 22 and the second driving assembly 24 are hydraulic cylinders; both ends of the second driving assembly 24 are respectively hinged to the mounting frame 10 and the gripper 23.

[0075] The beneficial effects of the silage wrapping unpacking device provided by the present utility model are as follows: Compared with the prior art, the silage wrapping unpacking device provided by the present utility model transports the silage wrapping to the lower side of the gripper 23 through the feeding assembly. During this process, the lower part of the wrapping is cut open by the cutting assembly, facilitating the subsequent tearing of the wrapping; then, the first driving assembly 22 drives the wrapping tearing assembly to move downward, and the second driving assembly 24 drives the two grippers 23 to close, hold the silage wrapping, and hook the wrapping skin through the hooking assembly; then it is driven upward by the first driving assembly 22, and the second driving assembly 24 drives the two grippers 23 to open, tear the wrapping, the silage feed drops, and the wrapping skin is hooked on the gripper 23, completing the unpacking operation, which is time-saving and labor-saving, and greatly improves the unpacking efficiency.

[0076] As Figure 1 and Figure 2 shown, in a specific implementation manner of the silage wrapping unpacking device provided by the embodiment of the present utility model, a plurality of teeth 231 extending toward the inner side of the gripper 23 are provided at the lower end of the gripper 23. The teeth 231 can penetrate into the wrapping when the gripper 23 holds the silage wrapping, facilitating grasping the wrapping during tearing.

[0077] As Figure 1 and Figure 3 shown, in a specific implementation manner of the silage wrapping unpacking device provided by the embodiment of the present utility model, the hooking assembly includes a hooking mechanism and a third driving assembly. The hooking mechanism includes a first rotating shaft 31 and a plurality of hooks 32. The first rotating shaft 31 is arranged outside the gripper 23 and is rotationally connected to the gripper 23. A plurality of hooks 32 are arranged on the first rotating shaft 31 at intervals along the axis direction of the first rotating shaft 31 and are connected to the first rotating shaft 31; the third driving assembly is connected to the gripper 23, and the power output end is connected to the first rotating shaft 31 to drive the first rotating shaft 31 to rotate; wherein, the hooks 32 extend out or retract into the inner side of the gripper 23 as the first rotating shaft 31 rotates.

[0078] Furthermore, as Figure 1 and Figure 3 shown, in a specific implementation manner of the silage wrapping unpacking device provided by the embodiment of the present utility model, the hooking assembly includes at least two hooking assemblies. The two hooking assemblies are arranged on the gripper 23 at intervals and are both rotationally matched with the gripper 23 to fully hook the wrapping skin and ensure the tearing effect.

[0079] The third driving assembly includes a connecting rod 34 and a third driving mechanism 33. The two ends of the connecting rod 34 are respectively rotatably connected to two adjacent first rotating shafts 31 to synchronously rotate the two first rotating shafts 31. The third driving mechanism 33 is connected to the gripper 23, and the power output end is connected to one of the first rotating shafts 31 to drive the first rotating shaft 31 to rotate. Thus, multiple first rotating shafts 31 can be driven to rotate simultaneously by one third driving mechanism 33, reducing the number of third driving mechanisms 33 required and lowering the cost.

[0080] Specifically, the third driving mechanism 33 is a hydraulic cylinder, an electric push rod, a pneumatic cylinder, etc. Preferably, the third driving mechanism 33 is an electric push rod. The two ends of the third driving mechanism 33 are respectively hinged to the first rotating shaft 31 and the gripper 23, and the axis of the electric push rod is skew to the axis of the first rotating shaft 31 to push the first rotating shaft 31 to rotate.

[0081] As Figure 7 and Figure 8 shown, in a specific embodiment of the silage wrapping unpacking device provided by the embodiment of the present invention, it further includes a first sensor 41, a second sensor 42 and a third sensor 43. The first sensor 41 is arranged on the lower side of the lifting frame 21 and connected to the lifting frame 21 to detect whether the distance between the lifting frame 21 and the wrapping reaches a first preset dimension, and is adapted to control the gripper 23 to close after reaching the first preset dimension. The second sensor 42 is connected to the mounting frame 10 to detect whether the descending distance of the lifting frame 21 reaches a second preset dimension, and is adapted to control the gripper 23 to close after reaching the second preset dimension. The third sensor 43 is connected to the mounting frame 10 to detect whether the distance between the lifting frame 21 and the mounting frame 10 reaches a third preset dimension, and is adapted to control the gripper 23 to open after reaching the third preset dimension.

[0082] It should be noted that the second preset dimension is the maximum distance that the lifting frame 21 is allowed to descend. If it continues to descend, the gripper 23 will collide with the feeding assembly. The sizes of different specifications of silage wrappings are different. For a smaller silage wrapping, the first sensor 41 is triggered first. At this time, the gripper 23 can be controlled to close and hold the silage wrapping. For a smaller silage wrapping, the second sensor 42 is triggered first, and the gripper 23 starts to close and hold the silage wrapping, effectively avoiding collision accidents. After holding the silage wrapping, it moves upward under the drive of the first driving assembly 22 until the third sensor 43 is triggered. At this time, it means that the silage wrapping has left the feeding assembly, and the gripper 23 can be controlled to open to start the unpacking operation.

[0083] Preferably, the first sensor 41 is an infrared distance sensor, and the second sensor 42 and the third sensor 43 are both proximity switches.

During this process, the bottom of the silage bale is cut open by the first saw blade 62 until the silage bale blocks the fourth sensor 44; at this time, the first conveyor 55 stops, and the fifth drive assembly 53 drives the traveling wheels 54 to rotate, driving the first conveyor 55 to move until the silage bale no longer blocks the fourth sensor 44; at this time, the silage bale is located under the gripper 23. Then, the gripper 23 can be controlled to hold the silage bale for bag tearing.

[0091] Specifically, the eighth drive assembly 64 is a component such as a cylinder, a hydraulic cylinder or an electric push rod that can output axial displacement, and is hinged to the mounting frame 10 and the side cutting frame 63 at both ends respectively; further, the eighth drive assembly 64 can also be a component such as a motor that can directly drive the side cutting frame 63 to rotate. The ninth drive assembly 65 is a motor assembly that can directly drive the second saw blade to rotate.

[0092] It should be noted that after the bale is conveyed to the lower side of the gripper 23 by the first conveyor 55, the eighth drive assembly 64 in the two side cutting mechanisms drives the side cutting frame 63 to rotate downward, driving the two second saw blades 66 and the ninth drive assembly 65 to move to the front and rear sides of the upper part of the bale. The second saw blades 66 cut the bale, and continuously cut the middle of the front and rear sides of the bale during the process of the gripper 23 holding the bale and moving upward, cutting open the bale wrapper to facilitate the gripper 23 to tear the bale wrapper.
