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.

[0022] Reference Figs. 1-3 The utility model provides an embodiment of an agricultural laser weeder, comprising a support base 1, the bottom wall of the support base 1 is fixedly connected to a bottom plate 17, both sides of the bottom wall of the bottom plate 17 are fixedly connected to support plates 18, and the two support plates 18 are rotatably connected to rollers 19 on the sides away from each other, a fixed shaft 2 is fixedly connected to the middle of the support base 1, a connecting shaft 5 is rotatably connected to the middle of the fixed shaft 2, a connecting rod 1 4 is fixedly connected to the rear side of the middle of the connecting shaft 5, a connecting rod 2 8 is fixedly connected to the front side of the middle of the fixed shaft 2, the connecting rod 1 4 is longer than the connecting rod 2 8, and the front end of the connecting rod 2 8 is fixedly connected to the rotating Shaft 9, both ends of the rotating shaft 9 are rotatably connected to a connecting seat 10, the front wall of the connecting seat 10 is fixedly connected to a support plate 3, the top wall of the support plate 3 is fixedly connected to a drive motor 11, the output end of the drive motor 11 passes through the support plate 3 and is fixedly connected to a laser disk 12, and laser emitters are evenly distributed in a ring shape on the periphery of the laser disk 12. The upper and lower sides of both ends of the fixed shaft 2 are rotatably connected to limit rod 1 6 and limit rod 2 7 respectively. The lengths of limit rod 1 6 and limit rod 2 7 are the same, and the front ends of the two limit rods 1 6 and limit rod 2 7 are rotatably connected to the two side walls of the connecting seat 10 respectively.

[0023] By making the connecting shaft 5 rotate, it can drive the front fixed connecting rod 2 8 to rotate along with the connecting shaft 5. When the connecting shaft 5 rotates, it will drive the connected rotating shaft 9 to move, and through the rotating shaft 9, drive the connected connecting seat 10 to rotate along with the connecting rod 2 8 with the connecting shaft 5 as the axis. Since the two sides of the connecting seat 10 are respectively connected to the two ends of the fixed shaft 2 by two limit rods, limit rod 1 6 and limit rod 2 7, and the lengths of limit rod 1 6 and limit rod 2 7 are constant, the connecting seat 10 can be limited under the action of limit rod 1 6 and limit rod 2 7, so that the connecting seat 10 will not rotate with the rotation of connecting rod 2 8, so that the connecting seat 10 can always be parallel to the horizontal plane while rotating around the fixed shaft 2.

[0024] Therefore, when the device is actually used, when the staff wants to adjust the cutting height of the device, the staff will drive the connecting shaft 5 connected at the front end to rotate with the fixed shaft 2 as the axis by pressing down or lifting the connecting rod 4, thereby driving the connecting seat 10 to rotate on the basis of ensuring parallel horizontal plane, thereby adjusting the height of the connecting seat 10. Since the front wall of the connecting seat 10 is connected to the support plate 3, the top wall of the support plate 3 is fixed with the driving motor 11 and the output end of the driving motor 11 is fixed with the laser disk 12, the height of the laser disk 12 can be adjusted on the basis of ensuring that the laser disk 12 is parallel to the horizontal plane, thereby enabling weeding from different heights, and under the action of the roller 19, when it is adjusted to the appropriate height, the connecting rod 4 can be pushed through the fixed shaft 2 to drive the support seat 1, the bottom plate 17 and the support plate 18 to move, thereby enabling the roller 19 to roll for easy operation. The worker pushes the lawn mower to move. At the same time, since the structure of the supporting roller 19 is simple and its own weight is relatively light, it is also convenient for the user to lift the device for a short period of time. The structure and driving method of the laser disk 12 quote the laser device structure disclosed in the Chinese patent announcement number: CN219961787U, an improved laser weeder. Therefore, the laser disk 12 is provided with evenly distributed laser emitters around it, and the laser disk 12 and the drive motor 11 are both electrically connected to the power source, and the power source is a backpack mobile power supply, which can be convenient for the user to carry on the body for movement and power the drive motor 11 and the laser disk 12. Then, the connected laser disk 12 is driven to rotate by the drive motor 11, so that the laser emitters provided on the laser disk 12 can burn the surrounding weeds to achieve the weeding effect.

[0025] The telescopic assembly is arranged in the connecting rod one 4, and is used for adjusting the overall length of the connecting rod one 4. The telescopic assembly comprises a push rod 13 which is slidingly connected in the connecting rod one 4, and the rear end of the push rod 13 penetrates through the rear end of the connecting rod one 4 and is rotationally connected with a threaded rod 15. The push rod 13 is a square rod, the inner wall of the connecting rod one 4 is a square cavity, the outer periphery of the two ends of the rear part of the push rod 13 is sleeved with an anti-skid sleeve 14, the front end of the threaded rod 15 penetrates through the front wall of the push rod 13 and the inner front wall of the connecting rod one 4 in sequence and is threadedly connected with the connecting rod one 4, a limiting cavity 20 is formed in the front part of the connecting rod one 4, the front end of the threaded rod 15 penetrates into the limiting cavity 20 and is fixedly connected with a limiting block 21, the two limiting blocks 21 can rotate in the connecting rod one 4, the limiting block 21 is slidingly connected with the inner wall of the limiting cavity 20, the outer periphery of the middle part and the rear part of the threaded rod 15 is fixedly connected with a stop block 16, and the front and rear stop blocks 16 abut against the front and rear walls of the push rod 13, respectively.

[0026] The threaded rod 15 can be driven to move along the connecting rod one 4 by rotating the threaded rod 15, and when the threaded rod 15 moves, the stop blocks 16 connected with the outer periphery move. Since the two stop blocks 16 abut against the front and rear ends of the push rod 13, the push rod 13 can be driven to move along the threaded rod 15 by the stop blocks 16 with the movement of the threaded rod 15. Therefore, when the staff wants to adjust the overall length of the connecting rod one 4, the push rod 13 can be driven to extend out of the connecting rod one 4 by rotating the threaded rod 15 to change the overall length of the connecting rod one 4, so that it can be used by different staff. Since the inner wall of the connecting rod one 4 is a square wall, the push rod 13 is a square rod and slides in the inner wall of the connecting rod one 4, the push rod 13 can be limited by the connecting rod one 4, so that the push rod 13 is prevented from rotating with the rotation of the threaded rod 15.
