To ensure stable lawnmower operation, the power distribution, power transmission direction, and power transmission stability of the power conversion drive system are crucial. Therefore, to address these issues, we propose a lawnmower power conversion drive system to plan the power distribution and power transmission direction, ensuring stable power transmission.

The output end of the engine is connected to the drive wheel of the V-belt transmission mechanism and the drive wheel of the primary belt transmission mechanism. The two sets of driven wheels of the V-belt transmission mechanism are respectively connected to the two sets of parallel blade shafts of the mowing device. The driven wheels of the primary belt transmission mechanism are coaxially connected to the drive wheels of the secondary belt transmission mechanism. The driven wheels of the secondary belt transmission mechanism are connected to the input shaft of a bevel gear commutator.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1As shown, this utility model provides a technical solution: a lawnmower power conversion drive device, including an engine 1, a mowing device 2, a drive wheel axle 3, a V-belt transmission mechanism 4, a primary belt transmission mechanism 5, and a secondary belt transmission mechanism 6. The engine 1 is integrated and mounted on the lawnmower frame via a housing, the mowing device 2 via a housing, and the drive wheel axle 3 via a bearing seat. The transmission shaft at the coaxial connection point of the primary belt transmission mechanism 5 and the secondary belt transmission mechanism 6 is mounted on the lawnmower frame via a connecting bracket. The mowing device 2 is located between the front and rear wheels of the lawnmower and is located below the chassis of the lawnmower. The V-belt transmission mechanism 4 is located below the primary belt transmission mechanism 5, and the secondary belt transmission mechanism 6 is located below the primary belt transmission mechanism 6. Above 5, the V-belt drive mechanism 4, the primary belt drive mechanism 5, and the secondary belt drive mechanism 6 are horizontally arranged and parallel to each other. The diameter of the driving pulley of the primary belt drive mechanism 5 is smaller than that of the driven pulley, and the diameter of the driving pulley of the secondary belt drive mechanism 6 is smaller than that of the driven pulley. Both the V-belt drive mechanism 4 and the secondary belt drive mechanism 6 are equipped with tension pulleys 13. The tension pulley 13 of the V-belt drive mechanism 4 is fixed to the outer shell of the mowing device 2, and the tension pulley 13 of the secondary belt drive mechanism 6 is fixed to the mowing machine frame through the bracket and the bevel gear reversing device 7. The tension pulley 13 improves the stability of the belt operation. After the V-belt drive mechanism 4 and the secondary belt drive mechanism 6 are installed, the belt is tensioned by installing the tension pulley 13.

[0018] The output end of engine 1 is connected to the drive pulley of V-belt drive mechanism 4 and the drive pulley of first-stage belt drive mechanism 5. The two sets of driven pulleys of V-belt drive mechanism 4 are respectively connected to the two sets of parallel blade shafts 201 of mowing device 2. The driven pulley of first-stage belt drive mechanism 5 is coaxially connected to the drive pulley of second-stage belt drive mechanism 6. The driven pulley of second-stage belt drive mechanism 6 is connected to the input shaft of bevel gear commutator 7. The drive wheel axle 3 is the rear wheel axle and is connected to the output end of bevel gear commutator 7.

[0019] Both the V-belt drive mechanism 4 and the secondary belt drive mechanism 6 have recessed reflectors 8 embedded on their outer surfaces to prevent wear. Photoelectric sensors 9 and 10, respectively, are positioned at the belt locations of the V-belt drive mechanism 4 and the secondary belt drive mechanism 6, facing the reflectors 8. The outputs of photoelectric sensors 9 and 10 are connected to a controller 11, and the output of the controller 11 is connected to an alarm 12. The controller 11 and the alarm 12 are mounted on the frame. Photoelectric sensor 9 is fixed to the outer casing of the mower device 2, and photoelectric sensor 10 can be fixed to the mower frame via a bracket. The belt operation of the V-belt drive mechanism 4 and the secondary belt drive mechanism 6 is monitored by photoelectric sensors 9 and 10. These sensors transmit belt speed information to the controller 11, which determines if there is an abnormality. If the speed is outside the set range, an alarm is triggered, providing timely feedback on power conversion issues. Faults are detected and promptly checked to prevent belt wear or equipment damage.
