For example, "connected" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the utility model can be understood according to specific circumstances.

[0032] Unless otherwise specified, the term "plurality" means two or more and "plurality" means two or more.

[0033] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.

[0034] like Figures 1 to 6 As shown, the utility model discloses a shredding device, including a bottom bin support 1, a rocker arm assembly 2 and a shredding knife 3. Figure 1 As shown in the figure, the bottom bin bracket 1 has a square shaft 11 arranged parallel to and close to the bottom bin rotating shaft; the rocker arm assembly 2 is connected to the end of the bottom bin bracket 1 away from the square shaft 11, including a driving shaft 21 rotatably connected to the bottom bin bracket 1, a swing arm 22 fixed to the driving shaft 21 and extending radially toward the shaft, and a cylinder mounting seat 23 fixed to both ends of the driving shaft 21; a plurality of shredder knives 3 are arranged in parallel and at intervals, and one end is rotatably connected to the square shaft 11, and the other end is connected to the end of the swing arm 22; wherein, the bottom bin bracket 1 has at least two mounting positions 12 for the driving shaft 21, and at least two cylinder mounting pins 13 corresponding to the mounting positions 12.

[0035] like Figure 4As shown in , when cutting is performed, the moving knife in the feeding system rotates to transport the grass picked up by the picking device backwards. When the grass needs to be cut, the oil cylinder drives the swing arm 22 to rotate, so that the chopping knife 3 can enter the range of rotation of the moving knife, and the cutting knife is in the gap between the moving knife blades, so that the grass can be chopped. When baling different straws, different cutting depths can be adjusted by changing the fixed positions of the rocker arm assembly 2 and the oil cylinder.

[0036] In the above embodiment, by providing at least two mounting positions 12 for mounting the driving shaft 21 and corresponding at least two mounting pins 13 for mounting the oil cylinder on the bottom bin bracket 1, when different straws need to be cut, it is only necessary to replace the mounting position 12 of the oil cylinder and the rocker arm assembly 2 to adjust the chopping depth. Compared with the method of multiple driving structures in the prior art, it not only reduces the structural components, but also reduces the cost, and is also convenient for maintenance and overhaul.

[0037] Alternatively, if Figure 2 As shown in , the end of the driving shaft 21 also has a limit plate that interferes with the bottom bin bracket 1 at a set position. Through the setting of the limit plate, the collision between the chopping knife 3 and the moving knife caused by excessive extension and contraction of the chopping knife 3 is avoided.

[0038] Alternatively, if Figure 1 As shown in the figure, the square shaft 11 is fixedly connected to the bottom bin bracket 1, and the shredder 3 is rotatably connected to the square shaft 11. In the prior art, the square shaft 11 is used for the rotation of the shredder 3, and it is easy to bend because when the shredder 3 rotates, the square shaft 11 is subjected to force and there is no support in the middle, so it is easy to deform; in the embodiment of the utility model, the square shaft 11 does not rotate and the shredder 3 rotates on the square shaft 11, thereby eliminating the bearing or sleeve required for the rotation of the square shaft 11 in the prior art, thereby reducing the shaking and deformation of the square shaft 11.

[0039] Alternatively, if Figure 5 As shown in FIG. 1 , magnets 14 are fixed on the square shaft 11 at equal intervals, and one side of the shredder 3 is adsorbed on the magnets 14. Please continue to refer to FIG. 1 for the fixing of the magnets 14. Figure 5, a fixing seat 111 is provided on the square shaft 11, and the other side of the magnet 14 is adsorbed on the fixing seat 111. In addition, in order to further improve the adsorption effect of the magnet 14, in some embodiments of the utility model, the magnet 14 is a circular structure. In this way, when the shredder 3 is driven, the extension and retraction of the oil cylinder drives the rotation of the swing arm 22. When the tension of the oil cylinder is greater than the magnetic force of the magnet 14, the shredder 3 can rotate around the square shaft 11. When the oil cylinder is extended to the set position, the tension of the oil cylinder is less than the magnetic force of the magnet 14, and the magnet 14 will tightly adsorb the shredder 3. Through this structural design, the shredder 3 will not shake or make abnormal sounds in the axial direction, and the structure is simple and easy to implement.

[0040] Alternatively, if Figure 6 As shown in the figure, the chopping knife 3 is detachably connected to the square shaft 11 and the swing arm 22. Of course, it should be pointed out here that in the embodiments of the present utility model, there are various detachable structural forms, such as fixed connection by bolts, or other snap-on structures. In some specific embodiments of the present utility model, such as Figure 6 As shown in the figure, one side of the chopping knife 3 has an open mounting hole 31, and the bottom of the other side has an open chute 32 for the shaft of the swing arm 22 to penetrate. The detachable design of the chopping knife 3 can achieve the cutting of straws of different lengths. In addition, in order to further improve the reliability of cutting, the chopping knife 3 has a cutting surface 33 arranged toward the moving knife, and the cutting surface 33 is arranged in a step-like manner. The step-like cutting surface 33 can be used to saw off the straw, thereby improving the reliability of cutting.

[0041] In an embodiment of the utility model, a baler is also provided, comprising any one of the above-mentioned shredding devices.

[0042] Application scenario of an exemplary embodiment:

[0043] like Figures 1 to 6 As shown, when baling straw or forage, the forage is fed into the feeding system by the rotation of the picker, and the forage is transported to the rear by the rotation of the moving knife. When the forage needs to be chopped, the rotation of the oil cylinder drives the swing arm 22 to make the chopping knife 3 rotate around the square axis 11 at a certain angle to enter between the moving knives, and the forage or straw is cut by the shearing action with the moving knife; when baling other straw, if a deeper cutting depth is required, the rocker arm assembly 2 and the installation position 12 of the driving oil cylinder can be changed before baling to adapt to different straw chopping requirements; in addition, when the cutting length of the forage or straw needs to be changed, it can also be achieved by disassembling part of the chopping knife 3.

[0044] The above description and the accompanying drawings fully illustrate the embodiments of the utility model so that those skilled in the art can practice them. Other embodiments may include structural and other changes. The embodiments represent only possible variations. Unless explicitly required, individual components and functions are optional, and the order of operations may vary. Parts and features of some embodiments may be included in or replace parts and features of other embodiments. The embodiments of the utility model are not limited to the structures described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the utility model is limited only by the appended claims.
