[0029] A moving cutter 5, the blade of the moving cutter 5 being perpendicular to the conveying direction of the bale conveying unit 2, the moving cutter 5 being movable along a direction perpendicular to the conveying direction of the bale conveying unit 2, and the moving cutter 5 being capable of ascending and descending relative to the bale conveying unit 2.

[0030] It should be noted that the bale is conveyed by setting the bale conveying unit 2. By setting the fixed cutter 4, during the bale conveying process, the fixed cutter 4 successively cuts the binding ropes perpendicular to the conveying direction of the bale conveying unit 2. By setting the moving cutter 5, during the bale conveying process, the moving cutter 5 successively cuts the binding ropes parallel to the conveying direction of the bale conveying unit 2, realizing automatic cutting of the binding ropes, with high work efficiency and reduced labor intensity of the operator; in the working state, the moving cutter 5 ascends, causing the top of the moving cutter 5 to be exposed above the bale conveying unit 2, facilitating the cutting of the binding ropes; in the idle state, the moving cutter 5 descends to achieve storage and avoid accidental injury.

[0031] In the bale rope cutting device of this embodiment, please refer to Figures 1 to 3 , the bale conveying unit 2 includes a plurality of sub-conveying units connected in transmission, and an installation space for accommodating the fixed cutter 4 and the moving cutter 5 is left between adjacent sub-conveying units.

[0032] It should be noted that the plurality of sub-conveying units are arranged in a straight line in sequence and are connected in transmission through a synchronous belt or a chain, etc. The bale conveying unit driving element 3 is used to drive the plurality of sub-conveying units to rotate synchronously to convey the bale. At the same time, an installation space for accommodating the fixed cutter 4 and the moving cutter 5 is left at the connection between the front and rear sub-conveying units, and a cover plate is buckled above the installation space. The tops of the fixed cutter 4 and the moving cutter 5 are exposed above the cover plate, and the cover plate can prevent forage from entering the installation space.

[0033] In the bale rope cutting device of this embodiment, please refer to Figures 1 to 3 , the fixed cutter 4 is rotatably arranged on the fixed cutter mounting seat, and the fixed cutter 4 is in transmission connection with the fixed cutter driving element, and the fixed cutter mounting seat is connected to the frame 1.

[0034] It should be noted that the fixed cutter 4 is driven to rotate by the fixed cutter driving element, and the rotation speed of the fixed cutter 4 is greater than the conveying speed of the bale conveying unit 2. The fixed cutter 4 can be located at any position within the width range of the bale conveying unit 2. Preferably, the fixed cutter 4 is located at the central axis of the bale conveying unit 2. In addition, the fixed cutter 4 can also be set as a lifting structure, which is used to cut the binding rope after rising and is convenient for storage after descending to avoid accidental injury.

[0035] In the bale rope cutting device of this embodiment, please refer toFigures 1 to 3 The moving cutter 5 is in transmission connection with the moving unit, the moving unit is arranged on the frame 1, and the moving unit drives the moving cutter 5 to move along a direction perpendicular to the conveying direction of the bale conveying unit 2.

[0036] Specifically, the moving unit includes a moving driving element 6 and a belt and pulley assembly 7. The running direction of the belt and pulley assembly 7 is perpendicular to the conveying direction of the bale conveying unit 2. The moving cutter 5 is installed on a moving cutter mounting seat 15, and the moving cutter mounting seat 15 is in transmission connection with the belt and pulley assembly 7.

[0037] It should be noted that the moving driving element 6 drives the belt and pulley assembly 7 to operate, and then drives the moving cutter 5 to move linearly. During this linear movement, the moving cutter 5 successively cuts the binding ropes parallel to the conveying direction of the bale conveying unit 2; by the forward and reverse rotation of the moving driving element 6, the reciprocating linear movement of the moving cutter 5 is realized.

[0038] In the bale rope cutting device of this embodiment, please refer to Figures 1 to 3 A first slide rail 8 is arranged on the frame 1, and a first slider 17 that can slide relative to the first slide rail 8 is arranged on the moving cutter mounting seat 15.

[0039] It should be noted that by arranging the first slide rail 8 and the first slider 17, it plays a guiding role in the linear movement of the moving cutter 5.

[0040] In the bale rope cutting device of this embodiment, please refer to Figures 1 to 3 The moving cutter 5 is in transmission connection with a lifting unit, the lifting unit is arranged on the moving cutter mounting seat 15, and the lifting unit drives the moving cutter 5 to lift relative to the bale conveying unit 2.

[0041] It should be noted that in the working state, the lifting unit drives the moving cutter 5 to rise, so that the top of the moving cutter 5 is exposed above the installation space, which is convenient for cutting the binding rope; in the idle state, the lifting unit drives the moving cutter 5 to descend, so that the moving cutter 5 is completely received in the installation space to avoid accidental injury.

[0042] In the bale rope cutting device of this embodiment, please refer to Figures 1 to 3 The moving cutter 5 is rotatably installed on the moving cutter mounting seat 15 through a cantilever 9. A limiting groove 11 inclined relative to its central axis is formed on the cantilever 9. The lifting unit includes a linear moving element 10 and a sliding member 12. The sliding member 12 supports the groove wall of the limiting groove 11, and the moving cutter 5 is lifted when the linear moving element 10 drives the sliding member 12 to move linearly.

[0043] Specifically, one end of the cantilever 9 is connected to the moving cutter mounting seat 15, and the other end is connected to the moving cutter 5. A tension spring 16 is provided between the middle of the cantilever 9 and the moving cutter mounting seat 15.

[0044] It should be noted that the linear moving element 10 is connected to the sliding member 12. During the process that the linear moving element 10 drives the sliding member 12 to move linearly, under the action of the tension spring 16, the sliding member 12 contacts different parts of the limiting groove 11. Since the limiting groove 11 is inclined relative to the central axis of the cantilever 9, when the sliding member 12 contacts different parts of the limiting groove 11, the moving cutter 5 performs a lifting motion.

[0045] In the bale cutting rope device of this embodiment, please refer to Figures 1 to 3 , the linear moving element 10 is connected to the moving cutter mounting seat 15. A second slide rail 14 is provided on the moving cutter mounting seat 15. The sliding member 12 is arranged on a second slider 13 that can slide relative to the second slide rail 14. The second slider 13 is in transmission connection with the linear moving element 10.

[0046] It should be noted that by providing the second slide rail 14 and the second slider 13, it plays a guiding role in the linear movement of the sliding member 12. Preferably, the sliding member 12 adopts a roller to reduce the friction between it and the groove wall of the limiting groove 11.
