DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figure 1-4 The cutting assembly of the forage harvester includes a fixed frame 1 and a base 7. The top of the front end of the fixed frame 1 is fixedly connected to a hinge seat 17. The bottom end of one side of the interior of the fixed frame 1 is fixedly installed with a first drive motor 6. The output end of the first drive motor 6 is fixedly connected to a threaded shaft 3. One side of the top of the interior of the fixed frame 1 is fixedly connected to a movable groove 2. The outside of the threaded shaft 3 is sleeved with a connecting seat 4. A fixed shell 5 is provided inside the fixed frame 1.

[0025] One side of the connecting seat 4 is fixedly connected to one side of the fixed shell 5, and the top end of the threaded shaft 3 is embedded in the movable groove 2 and can rotate;

[0026] There are two groups of threaded shafts 3, which are symmetrically distributed on both sides of the fixed frame 1;

[0027] Specifically, if Figure 1 and Figure 4 As shown, the first driving motor 6 is turned on to drive the threaded shaft 3 to rotate, which can drive the sleeved connecting seat 4 to move up and down, thereby facilitating the adjustment of the cutting height according to the height of the grass during cutting, which is more suitable for cutting.

[0028] Example 2: A square groove 15 is provided at the top of the fixed shell 5, a second reserved groove 13 is provided at the front end of the fixed shell 5, a collection box 14 is provided inside the second reserved groove 13, and a handle 16 is fixedly connected to the top of the collection box 14;

[0029] There are three groups of collection boxes 14, which are evenly spaced and distributed inside the fixed shell 5. The collection boxes 14 are detachably embedded in the second reserved grooves 13, and the positions of the collection boxes 14 and the square grooves 15 are consistent.

[0030] A first reserved groove 8 is provided inside the base 7, a second drive motor 9 is fixedly installed inside the first reserved groove 8, an output end of the second drive motor 9 is fixedly connected to a connecting shaft 10, a top end of the connecting shaft 10 passes through the top end of the first reserved groove 8 and is fixedly connected to a fixing seat 11, a cutting knife 12 is fixedly connected to the outside of the fixing seat 11, and the second drive motor 9 is provided with three groups;

[0031] Specifically, if Figure 1 and Figure 3 As shown, turn on the second drive motor 9, drive the connecting shaft 10 to rotate, and drive the fixed seat 11 to rotate, so that the cutting knife 12 outside the fixed seat 11 can cut the grass. Since a collection box 14 is provided behind each cutting component, the grass can fall into the collection box 14 through the second reserved groove 13. After that, the collection box 14 can be easily taken out from the square groove 15 using the handle 16 on the top, so that the collection function can be realized.

[0032] Embodiment 3: A fixed sleeve 18 is movably hinged between the hinge seats 17, and a protective cover 19 is fixedly connected to the top of the fixed sleeve 18;

[0033] The length and width of the protective cover 19 are the same as those of the fixed frame 1 , and the protective cover 19 can be flipped at the front end of the fixed frame 1 ;

[0034] Specifically, if Figure 1 and Figure 2 As shown, when not in use, the protective cover 19 can be flipped down by utilizing the movable hinge relationship between the fixing sleeve 18 and the hinge seat 17 to cover the front end of the fixing frame 1, thereby providing a certain degree of protection and preventing the staff from being scratched by the cutting knife 12 when not in use.

[0035] Working principle: When the present invention is in use, first, turn on the first drive motor 6, drive the threaded shaft 3 to rotate, and drive the sleeved connecting seat 4 to move up and down, so that the cutting height can be adjusted according to the height of the grass during cutting, which is more suitable for cutting. Afterwards, turn on the second drive motor 9, drive the connecting shaft 10 to rotate, and drive the fixed seat 11 to rotate, so that the cutting knife 12 outside the fixed seat 11 can cut the grass. Because a collection box 14 is provided at the rear of each cutting component, it can fall into the collection box 14 through the second reserved groove 13. Afterwards, the collection box 14 can be easily taken out from the square groove 15 using the handle 16 on the top, so that the collection function can be realized. Finally, when not in use, the protective cover 19 can be flipped down to cover the front end of the fixed frame 1 by using the movable hinged relationship between the fixed sleeve 18 and the hinged seat 17, so that it can have a certain degree of protection to prevent the staff from being scratched by the cutting knife 12 when not in use.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
