[0026] A second drive assembly 21 having one end fixedly connected to the outer side of the worm 20 is fixedly installed at the bottom of the cross plate 13. The second drive assembly 21 includes a servo motor 211. A servo motor 211 located between two threaded rods 14 is fixedly installed at the bottom of the cross plate 13. The model of the servo motor 211 may be MR-J2S-10A. A driving gear 212 is fixedly installed on the output shaft of the servo motor 211. A driven gear 213 having one end meshing with the driving gear 212 is fixedly installed on the outer side of the worm 20.

[0027] When in use, the servo motor 211 can be started by an external controller to drive the driving gear 212 to rotate, and then the worm 20 is driven to rotate through the driven gear 213, and then the two worm wheels 19 drive the two threaded rods 14 to rotate synchronously. During the rotation of the two threaded rods 14, the two threaded sleeves 15 drive the movable plate 16, the two support blocks 17 and the four universal wheels 18 to move downward as a whole until the four universal wheels 18 contact the ground and lift the entire grass mower. At this time, the bottoms of the four supporting feet 2 are all in a suspended state, and the entire grass mower is supported by the four universal wheels 18. The grass mower can be moved by pushing the casing 4, so as to transport the grass mower to the position where it is needed. Before use, the servo motor 211 can be started by an external controller to rotate in the opposite direction, so as to drive the worm 20 and the threaded rod 14 to rotate in the opposite direction. At this time, the two threaded rods 14 are in the process of rotation. In the middle, two threaded sleeves 15 are used to drive the moving plate 16, two supporting blocks 17 and four universal wheels 18 to move upward as a whole until the bottoms of the four universal wheels 18 are in a suspended state. At this time, the entire grass cutter is supported by four supporting feet 2, thereby ensuring stability during use. Then, the driving motor 121 can be started by an external controller to drive the driving bevel gear 122 to rotate, and then the driven bevel gear 123 is used to drive the mounting shaft 7, the mounting column 8, the fan blade 9 and the double-edged chopping blade 10 to rotate as a whole. At this time, agricultural raw materials such as corn stalks, wheat straw or rice straw can be inserted into the interior of the casing 4 through the feed pipe 5, wherein the double-edged chopping blade 10 will chop the raw materials during the rotation process, and the fan blade blade 9 will generate wind force during the rotation process, and then the chopped raw materials will be directly thrown out from the discharge pipe 11, so as to carry out the chopping and processing of the forage.

[0028] In summary, the air-conveyed disc double-edged grass cutter for cutting forage grass drives the driving gear 212 to rotate by starting the servo motor 211, and then drives the worm 20 to rotate through the driven gear 213, and then the two worm wheels 19 drive the two threaded rods 14 to rotate synchronously, and the two threaded rods 14 will drive the moving plate 16, the two support blocks 17 and the four universal wheels 18 to move downward as a whole through the two threaded sleeves 15 during the rotation process, until the four universal wheels 18 contact the ground and then The entire grass mower is lifted up, and the bottoms of the four supporting legs 2 are in a suspended state. The entire grass mower is supported by four universal wheels 18. The grass mower can be moved by pushing the casing 4, thereby achieving the purpose of easy movement and facilitating the transportation of the grass mower. This solves the problem that the existing air-conveyed disc double-edged grass mowers are not convenient to move during use because most of the grass mowers are installed on the frame, which makes it inconvenient to move, resulting in inconvenience in carrying the grass mower according to processing needs, which is not conducive to use.
