[0025] As attached Figure 1 To be continued Figure 6 As shown:

[0026] This utility model provides an automated agricultural machinery-equipped weeder, including a main housing 1. A secondary housing 2 is hinged to both sides of the main housing 1 via hinge shafts. A protective cover 3 is fixedly installed on the top of the main housing 1. A connecting frame 4 is installed on the top of the protective cover 3. Hydraulic cylinders 5 are hinged to both sides of the connecting frame 4. Hinge seats are fixedly installed on the tops of both secondary housings 2, and the output ends of both hydraulic cylinders 5 are hinged to their corresponding hinge seats. A through hole is opened on one side of the top of each of the secondary housings 2. A drive shaft 7 is rotatably connected inside the through hole. One end of each drive shaft 7 extends to the bottom side of the secondary housing 2 and is fixedly connected to a weeding blade 8. A through hole is opened on the top of the main housing 1, inside the protective cover 3. A drive shaft 9 is rotatably connected inside the through hole. One end of each drive shaft 9 extends to the bottom side of the main housing 1 and is fixedly connected to a weeding blade 10.

[0027] The protective cover 3 is equipped with a diesel drive motor 11 at its top. The output end of the diesel drive motor 11 is coaxially connected to a reducer 12. The output end of the reducer 12 is equipped with a rotating shaft 13. One end of the rotating shaft 13 extends into the interior of the protective cover 3 and is fixedly equipped with a synchronous pulley 1. The other end of the transmission shaft 9 is fixedly equipped with a synchronous pulley 2. The synchronous pulley 1 and the synchronous pulley 2 are connected by a synchronous belt 14.

[0028] Two sets of protective covers 15 are fixedly installed on the top of the auxiliary housing 2. The other end of the drive shaft 7 extends into the protective cover 15 and is fixedly connected to a helical gear 16. A helical gear 17 meshes with one side of the top of the helical gear 16. A connecting shaft 18 is installed at the center of each helical gear 17. A universal coupling 19 is installed at one end of each connecting shaft 18. A helical gear 20 is installed at the bottom of the rotating shaft 13 and directly below the synchronous pulley 1. A helical gear 20 meshes with a helical gear at the bottom of the helical gear 20. The fourth gear 21 has a connecting shaft 22 installed at its center. Both ends of the connecting shaft 22 extend to the outside of the protective cover 3 and are fixedly connected to the other ends of the two sets of universal couplings 19. This ensures that when the auxiliary housing 2 is unfolded, the power can still be stably transmitted to the weeding blade 8 through the first helical gear 16 and the second helical gear 17, avoiding transmission failure due to angle changes. At the same time, the third helical gear 20 at the bottom of the rotating shaft 13 meshes with the fourth helical gear 21, diverting the power to the universal couplings 19 on both sides to ensure the same rotational speed as the weeding blade 8.

[0029] The main housing 1 and the auxiliary housing 2 are equipped with multiple sets of bearing seats 23. The center of each bearing seat 23 is rotatably connected to the connecting shaft 18 and the connecting shaft 22, which can provide multi-point support for the connecting shaft 18 and the connecting shaft 22, reduce the bending deformation of the shaft caused by vibration or eccentric load, extend the service life of the transmission components, and improve the power transmission efficiency.

[0030] The main housing 1 has symmetrically mounted fixing plates 33 on one side. A fixing shaft 24 is rotatably connected between the two sets of fixing plates 33. Two sets of sleeves 25 are fixedly connected to the outside of the fixing shaft 24. A support rod 26 is slidably connected inside each sleeve 25. A universal wheel 27 is installed at the bottom end of each support rod 26. Multiple sets of threaded holes are opened on the outside of the support rod 26. A through hole is opened on the outside of the sleeve 25. A Phillips head bolt 28 is connected to one side of the through hole. One end of each Phillips head bolt 28 passes through the through hole and is threaded into any of the threaded holes. The height of the universal wheel 27 can be manually adjusted to adapt to different terrains or crop heights, ensuring reasonable contact pressure between the weeding blade and the ground. At the same time, the Phillips head bolt 28 can be operated without tools, improving adjustment efficiency. The universal wheel 27 can give the equipment multi-directional movement capability, making it easy to turn and drag in complex terrain.

[0031] The main housing 1 has a protective cover 29 fixedly installed on the top of the main housing 1 and on one side of the protective cover 3. The protective cover 29 has a drive motor 30 installed inside, and a worm gear 31 is fixedly installed at the output end of the drive motor 30. A worm wheel 32 is fixedly installed on the outside of the fixed shaft 24. The worm wheel 32 and the worm gear 31 mesh with each other, which facilitates the adjustment of the support rod 26. The adjustment process is smooth and highly accurate. At the same time, the self-locking characteristic of the worm wheel 32 and the worm gear 31 can automatically lock the height after adjustment, preventing the support rod 26 from being displaced due to vibration during operation.

[0032] The main housing 1 has a towing frame 6 fixedly installed on one side of the protective cover 3, which facilitates quick connection between the equipment and agricultural machinery, and ensures the stability of the equipment during towing.

[0033] The working principle of this embodiment:

[0034] When using the weeder, first connect the device to the agricultural machinery via the towing frame 6 and move it to the area where weeding is required. Then, activate the hydraulic cylinder 5 as needed. The hydraulic cylinder 5, fixed on both sides of the connecting frame 4, pushes the auxiliary housing 2 to unfold around the hinge shaft, thereby adjusting the horizontal working range of the weeding blade 8. Then, start the diesel drive engine 11, which drives the reducer 12 to rotate, and drives the rotating shaft 13 and the first synchronous pulley to rotate. Through the synchronous belt 14, it drives the second synchronous pulley and the second transmission shaft 9, which in turn drives the second weeding blade 10 to work. The helical gear 3 20 at the bottom of the rotating shaft 13 meshes with the helical gear 4 21, transmitting power to the second connecting shaft 22, and then driving the helical gear through the universal coupling 19 and the first connecting shaft 18. The second 17 ultimately drives the drive shaft 7 and the weeding blade 8 to rotate. When it is necessary to adjust the ground height of the universal wheel 27, loosen the plum blossom handle bolt 28, slide the support rod 26, and move it to the target height within the sleeve 25. Then, tighten the plum blossom handle bolt 28 to lock the sleeve 25 and the support rod 26, thereby completing the height adjustment of the universal wheel 27. Subsequently, the agricultural machinery can drive the weeder to work. When encountering weeds of different heights or undulating ground, start the drive motor 30. The drive motor 30 drives the worm gear 31 to rotate, which drives the worm wheel 32 and the fixed shaft 24 to rotate, achieving automatic adjustment, thereby maintaining reasonable contact between the blade and the ground, and thus completing the full-coverage weeding operation in complex terrain.

[0035] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
