Description

Technical Field

[0001] This invention relates to the field of garden machinery technology, specifically a multifunctional lawn mowing device for gardens. Background Technology

[0002] A lawnmower is a handheld tool used to cut weeds in lawns, gardens, pastures, and other similar areas. Based on the power source, it can be divided into hydraulic and electric types; based on the power head structure, it can be divided into front-powered and rear-powered types.

[0003] Currently, when using existing lawnmowers, the grass is shattered and splashed around, and the shattered grass, along with its juice, adheres to the surface of the lawnmower, resulting in a large amount of shattered grass adhering to the surface. Furthermore, when the internal wheel of the lawnmower rotates at high speed, the shattered grass accumulates on the inner wall of the protective cover, which is difficult to clean. As a result, existing lawnmowers cannot perform simultaneous cleaning of the surface and inner wall, nor can they guide the shattered grass. Therefore, an improved device is needed to address these problems. Summary of the Invention

The L-shaped extension rod 31 moves in the sliding groove inside the top end of the protective cover plate 32, so that the rack 38 can move in a straight line.

[0055] L-shaped air cylinders 10 are symmetrically fixedly installed on the top of the support chassis 19 away from the worm gear 15. The top center of the synchronous frame 8 is connected to the bottom of the rear end of the L-shaped extension rod 31.

The air collecting chamber 27 is fixedly installed on both sides of the protective cover plate 32 near the vertical guide rod 34. The protective cover plate 32 is fixedly installed on the top of the support chassis 19. The worm gear 15 meshes with the worm 35. The interior of the L-shaped air cylinder 10 is hollow. A sealed cavity is formed between the first piston rod 9, the L-shaped air cylinder 10 and the second piston rod 11. The top rear end of the support chassis 19 is provided with insertion holes and slots that are compatible with the connecting rod 12 and the first scraper 13. The two ends of the second scraper 36 are provided with round holes. The vertical guide rod 34 is inserted through the round holes. The fifth gear 29 meshes with the rack 38.

[0056] The third gear 22, transmission belt 23, fourth gear 24, fan blade 25, exhaust port 26, and air collection chamber 27 are each provided on the other side of the protective cover plate 32. The third gear 22, transmission belt 23, and fourth gear 24 are arranged in an up-down staggered manner. A round wheel is rotatably mounted on the front end of the first piston rod 9. The rear end surface of the first scraper 13 is in contact with the rear bottom end of the support chassis 19. The first gear 16 meshes with the second gear 17. The cam 18 is vertically aligned with the first piston rod 9. The interior of the air collection chamber 27 is hollow. The exhaust port 26 is interconnected with the air collection chamber 27. The exhaust port 26 is inclined at 45° on the bottom end of the air collection chamber 27. The rear end surface of the worm gear 35 is in contact with the front end surface of the protective cover plate 32. The winding wheel 28 is symmetrically rotatably mounted on the top of the drive motor 30. A sliding groove adapted to the L-shaped extension rod 31 is opened at the rear end of the top of the protective cover plate 32.

[0057] The working principle of Example 1 is as follows: During use, the user can hold the support extension rod 2 to lift the entire device. Then, the drive motor 30 is started, causing the connecting shaft 33, worm gear 35, and sweeping rope 14 to rotate simultaneously. The sweeping rope 14 contacts the weeds, cutting them. Simultaneously, when the connecting shaft 33 rotates, it drives the third gear 22 to rotate. The third gear 22 can drive the fourth gear 24 to rotate via the transmission belt 23. The fan blade 25 is fixedly installed on the bottom of the fourth gear 24, so that when the fourth gear 24 rotates, it drives the fan blade 25 to rotate simultaneously. This allows the fan blade 25 to pump outside air into the air-collecting chamber 27. At the same time, the exhaust port 26 communicates with the air-collecting chamber 27, allowing the air to be collected... Air inside the air chamber 27 can be discharged from the exhaust port 26. The exhaust port 26 is positioned at a 45° angle, allowing it to blow air forward, thus propelling the chopped grass forward and preventing it from splashing backward. Simultaneously, when the sweeping rope 14 cuts the grass, the grass fragments will splash onto the inner wall of the supporting chassis 19. At this time, the worm gear 35 rotates, driving the worm wheel 15 to rotate. The rotation of the worm wheel 15, in turn, drives the second gear 17 and the cam 18 to rotate simultaneously via the first gear 16. This allows the cam 18 to rotate until it contacts the front end of the first piston rod 9. A wheel is mounted on the front end of the first piston rod 9 to improve the smoothness of contact between the cam 18 and the first piston rod 9. When the cam 18 protrudes... When rotated to align with the front end of the first piston rod 9, the first piston rod 9 can be squeezed to move into the L-shaped air cylinder 10 to its limit position. This allows the second piston rod 11 to drive the connecting rod 12 and the first scraper 13 to move downwards. The rear end surface of the first scraper 13 then contacts the rear end of the inner wall of the support chassis 19, allowing the first scraper 13 to scrape away the grass debris adhering to the inner wall of the support chassis 19 during its descent. Simultaneously, as the first piston rod 9 moves into the L-shaped air cylinder 10, it drives the synchronous frame 8 and the L-shaped extension rod 31 to move synchronously to the rear end, allowing the rack 38 to pass under the fifth gear 29. At this point, as the rack 38 moves to the rear end, it drives the fifth gear 29 to rotate. When the fifth gear 29 rotates, it drives... The take-up reel 28 rotates, causing it to pull the second scraper 36 upward via the connecting rope 37. The rear surface of the second scraper 36 contacts the front surface of the protective cover 32, allowing it to scrape away the grass debris adhering to the front surface of the protective cover 32 as it moves upward. Simultaneously, the connecting rope 37 passes over the outer ring of the guide wheel 39, using the guide wheel 39 as a fulcrum to pull the second scraper 36 upward. The two ends of the second scraper 36 are slidably fitted onto the vertical guide rod 34, ensuring that the second scraper 36 moves vertically in a straight line. Then, when the protruding part of the cam 18 rotates past the front end of the first piston rod 9, a return spring is fixedly installed at the bottom end of the second piston rod 11.The bottom end of the return spring is connected to the top end of the support chassis 19. The spring force of the return spring can drive the second piston rod 11 upwards until the first scraper 13 returns to its original position. Simultaneously, when the second piston rod 11 moves into the L-shaped air cylinder 10, it can drive the first piston rod 9 to move forward, allowing the first piston rod 9 to return to its original position. Furthermore, as the first piston rod 9 moves, it can also drive the synchronous frame 8 and the L-shaped extension rod 31 to move forward again, allowing the rack 38 to move forward and the fifth gear 29 to rotate in the opposite direction. This causes the winding wheel 28 to release the connecting rope 37. At this point, the second scraper 36 will slide downwards to its original position, completing the cleaning work between the front end of the protective cover 32 and the inner wall of the bottom end of the support chassis 19.

[0058] Example 2

[0059] Based on Example 1, such as Figure 10 As shown, the support extension rod 2 also includes an upper end plate 40, a hydraulic cylinder 41, a wheel 42, and a lower end plate 43. The upper end plate 40 is fixedly installed on the support extension rod 2, the hydraulic cylinder 41 is fixedly installed on the bottom end of the upper end plate 40, the lower end plate 43 is fixedly installed on the bottom end of the hydraulic cylinder 41, and the wheel 42 is rotatably installed at the center of both ends of the lower end plate 43.

[0060] When implementing this embodiment, when the device is working on a relatively flat surface, the wheels 42 contact the ground, allowing the user to push the device along the ground, avoiding the user from lifting the device for a long time. At the same time, the hydraulic cylinder 41 can be activated, driving the upper plate 40 to move upward as a whole, so that the cutting height of the sweeping rope 14 can be changed, making it easy to adjust the cutting height of the sweeping rope 14, improving the aesthetics of lawn mowing, and completing the work.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
