[0002] A straw shredder is a device used to chop various forages such as rice straw, wild grass, wheat straw, and corn stalks. A search revealed a patent with application number 202121902108.1, which discloses a lightweight straw shredder, relating to the field of straw shredding equipment technology. The shredder includes a machine body, a drive wheel, serrated blades, support rollers, a support rod, a traveling box, a vibration structure, and a protective cover. The protective cover is welded to the front of the machine body, and a cutter shaft is mounted inside the protective cover via bearings. Serrated blades are arranged around the circumference of the cutter shaft.

[0003] However, during actual use, the applicant found that the chassis of the machine is fixed during the grass chopping process, making it impossible to adjust the distance between the serrated blades and the ground by adjusting the height of the grass chopping roller according to the actual grass chopping needs. In view of this, we propose a lithium battery grass chopper with a liftable chassis. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A lithium-ion battery-powered grass shredder with a liftable chassis includes a frame 1. A chassis 2 is movably connected through the top of the frame 1. A threaded sleeve 21 is fixedly installed on the top of the chassis 2. A support frame 3 is fixedly connected to the top of the frame 1 outside the chassis 2. Guide sliders are symmetrically arranged on both sides of the upper part of the chassis 2, and the guide sliders slide along guide grooves opened on the inner sidewall of the support frame 3. A screw 10 is rotatably connected to the middle of the support frame 3 via a bearing. The lower end of the screw 10 is threaded into the threaded sleeve 21, and an adjusting disc 101 is sleeved and fixed to the upper end of the screw 10. The chassis 2 is located behind the threaded sleeve 21. A motor 4 is fixedly installed on the top of the chassis 2. A trough roller 12 is rotatably connected to the lower part of the chassis 2. The outer wall of the trough roller 12 is evenly provided with serrated blades. The motor 4 is connected to the chassis 2 via a belt. The output end of the motor 4 and one end of the roller shaft in the middle of the trough roller 12 are both fitted with pulleys. The two pulleys are driven by the belt. A protective cover 11 is fixedly installed on the bottom of the chassis 2 outside the trough roller 12. By manually rotating the adjusting disc 101 clockwise, the screw 10 is driven to rotate. The screw 10 rotates inside the threaded sleeve 21, which can drive the guide slider on the chassis 2 to move downward along the guide groove on the support frame 3, thereby driving the trough roller 12 to move downward. The height of the trough roller 12 from the ground can be flexibly adjusted to better meet the needs of grass shredding. A lithium battery pack 5 is fixed on the top of the frame 1 at the rear of the chassis 2. The two sides of the frame 1 below the lithium battery pack 5 are symmetrically connected to drive wheels 8 via wheel axles. Support rollers 9 are symmetrically installed on the bottom of the front side of the frame 1. A pusher 6 is fixedly installed on the rear side of the machine, and a controller 7 is fixedly installed on the pusher 6. The controller 7 is electrically connected to the lithium battery pack 5 through wires. A motor for driving the wheel axle to rotate is embedded in the frame 1 below the lithium battery pack 5. The motor and the motor 4 are electrically connected to the controller 7 through wires. In use, the controller 7 can drive the motor 4 and the motor inside the frame 1 to rotate. The motor 4 can drive the chaff roller 12 to rotate to shred grass. The operator can hold the pusher 6 by hand, and the motor drives the wheel axle and drive wheel 8 to rotate. With the help of the support roller 9, the grass shredder moves forward. When it is necessary to raise and lower the chassis 2 to adjust the distance between the chaff roller 12 and the ground, the adjustment disc 101 can be manually rotated clockwise to drive the screw 10 to rotate. The screw 10 rotates inside the threaded sleeve 21, which can drive the guide slider on the chassis 2 to move downward along the guide groove on the support frame 3, and thus drive the chaff roller 12 to move downward. The height of the chaff roller 12 from the ground can be flexibly adjusted.

[0022] A reducer 13 is fixedly connected to the side of the protective cover 11 away from the belt. The input end of the reducer 13 is coaxially connected to the roller shaft of the crushing roller 12. A cam 14 is sleeved and fixed to the output end of the reducer 13. A swing bracket 15 is rotatably connected to the protective cover 11 behind the cam 14. A rotating shaft 16 is fixedly connected to the side wall of the protective cover 11. The middle part of the swing bracket 15 is rotatably connected to the rotating shaft 16 through a bearing. The front end of the swing bracket 15 is located below the cam 14, and the rear end of the swing bracket 15 extends to the rear side of the protective cover 11. A hammer 17 for striking the protective cover 11 is fixedly connected to the rear end of the swing bracket 15. By driving the cam 14, the swing bracket 15 is driven to swing intermittently around the rotating shaft 16, which in turn drives the hammer 17 to rotate around the rotating shaft 16, and the hammer 17 is struck. Intermittently striking the protective cover 11 with hammer 17 can dislodge the blades and dirt adhering to the inner wall of the protective cover 11, reducing the difficulty of cleaning the inner wall of the protective cover 11. The hammer 17 is fixedly connected to the rear end of the swing bracket 15 near the protective cover 11. As the crushing roller 12 rotates with the roller shaft, the roller shaft can drive the input end of the reducer 13 to rotate rapidly. After being reduced in speed by the reduction gear inside the reducer 13, the output end of the reducer 13 drives the cam 14 to rotate. The rotation of the cam 14 can drive the swing bracket 15 to swing intermittently around the rotating shaft 16. The swing bracket 15 can drive the hammer 17 to rotate around the rotating shaft 16, and the hammer 17 can intermittently strike the protective cover 11, dislodge the blades and dirt adhering to the inner wall of the protective cover 11.

[0023] Working principle: During use, the controller 7 drives the motor 4 and the motor inside the frame 1 to rotate. The motor 4 drives the shredding roller 12 to rotate and shred the grass. The operator can push the shredder by holding the handle 6, which drives the axle and drive wheel 8 to rotate. Together with the support roller 9, the shredder moves forward. As the shredding roller 12 rotates with the roller shaft, the roller shaft drives the input end of the reducer 13 to rotate rapidly. After being reduced in speed by the reduction gear inside the reducer 13, the output end of the reducer 13 drives the cam 14 to rotate. The rotation of the cam 14 causes the swing bracket 15 to swing intermittently around the rotating shaft 16. The swing bracket 15 drives the hammer 17 to rotate around the shaft 16, and the hammer 17 intermittently strikes the protective cover 11, causing the blades and soil attached to the inner wall of the protective cover 11 to fall off. When it is necessary to raise and lower the chassis 2 to adjust the distance between the crushing roller 12 and the ground, the adjusting disc 101 can be manually rotated clockwise to drive the screw 10 to rotate. The screw 10 rotates inside the threaded sleeve 21, which can drive the guide slider on the chassis 2 to move downward along the guide groove on the support frame 3, thereby driving the crushing roller 12 to move downward, so as to flexibly adjust the height of the crushing roller 12 from the ground.
