[0045] Specifically, a lawn mower is a mechanical tool used to trim lawns, plants, etc. However, in the existing lawn mowers, it is inconvenient to collect the cut grass clippings during the cutting process, resulting in the grass clippings being scattered on the lawn, which affects the neatness and beauty of the lawn. In addition, the grass clippings can be used as feed after being collected, and it is a waste of resources if the grass clippings are not collected and scattered on the lawn.

[0046] Therefore, when the present embodiment is in use, a driving device is used to rotate the blade 5 to cut the grass. While cutting, the vehicle body 1 is also moving. When the cut grass clippings are in the middle of the vehicle body 1, the motor 11 is started and drives the connecting rod 12 to rotate, so that the clamping box 15 moves, so that the clamping box 15 passes through the middle of the vehicle body 1 and contacts the ground, and then the motor 6 32 is started to drive the bidirectional threaded rod 30 to rotate, so that the threaded blocks 31 on both sides slide simultaneously and approach each other. When the clamping boxes 15 are fitted together, the grass clippings can be collected inside the clamping boxes 15, and then the motor 11 drives the connecting rod 12 to rotate again, so that the clamping box 15 rises and aligns with the top of the screen drum 14. At this time, the drum cover 38 is not aligned with the screen drum 14. The two clamping boxes 15 are closed, and then the two clamping boxes 15 are driven to move away from each other again. At the same time, the motor 5 29 is used to drive the two clamping boxes 15 to rotate in different directions at the same time, so that the clamping boxes 15 are tilted, and the grass clippings inside are poured into the screen drum 14. When there are enough grass clippings inside the screen drum 14, the motor 2 13 is started to drive the rotating arm 34 to rotate 90 degrees, so that the screen drum 14 changes from longitudinal to transverse, and then the motor 7 36 is started to drive the gear 2 37 to rotate, so that the screen drum 14 rotates on the fixing ring 35. When the screen drum 14 rotates, the grass clippings will move with the screen drum 14 and form a falling effect, so that the soil and impurities in the grass clippings can be screened out from the sieve holes 33, thereby improving the purity and safety of the grass clippings as feed;

[0047] During the screening process, soil or impurities may clog the sieve holes 33. At this time, the sieve drum 14 can be restored to a vertical state, and the motor 7 36 can be used to drive the gear 2 37 to rotate, so that the sieve drum 14 can rotate intermittently. When the sieve drum 14 stops, a row of sieve holes 33 coincides with the axis of multiple fixed disks 24. Then, the electric push rod 18 is started to drive the rectangular plate 20 to move, so that the scraper 25 extends into the sieve holes 33. Then, the motor 23 is used to drive the turntable 40 to rotate, so that multiple connecting rods 27 are rotated, so that the sliding rods 26 slide on the fixed disk 24, so that multiple scrapers 25 fit the hole walls of the sieve holes 33. Then, the electric push rod 18 is used to move the scraper 25 from the sieve holes 33, so that the soil and impurities attached to the hole walls of the sieve holes 33 can be scraped out. However, since the scraper 25 has a limited angle, a single scraping is limited. If it is not enough to scrape all the positions of the hole wall of the sieve hole 33, the scraper 25 can be moved out of the hole wall, and the motor 3 19 can be started to drive the multiple gears 1 21 to rotate, so as to adjust the angle of the scraper 25, and then the scraper 25 can be extended into the sieve hole 33 again to scrape again. By repeating the above operation, the soil and impurities attached to the hole walls of all the sieve holes 33 can be scraped, thus avoiding the clogging of the sieve holes 33 and ensuring the use effect of the sieve drum 14; thereby, the anti-clogging grass clippings collection mechanism can be used to collect grass clippings during mowing, thus ensuring the cleanliness of the lawn, and the impurities and soil in the collected grass clippings can be filtered, so that the grass clippings can be better used as feed, and at the same time, the hole wall of the sieve hole 33 used for filtering impurities can be cleaned to avoid the clogging of the sieve hole 33, and the recycling effect is good.

[0048] In this embodiment, Figure 1 As shown, a water tank 2 is fixedly connected to the front side of the upper end of the vehicle body 1, a water pump 3 is connected to the front end of the water tank 2, a long tube 4 is connected to the water outlet of the water pump 3, both ends of the long tube 4 are fixedly connected to the vehicle body 1, and a plurality of nozzles 41 are arranged at the lower end of the long tube 4, and the nozzles 41 face the blade 5;

[0049] Specifically, water in the water tank 2 is pumped out by the water pump 3, and then sprayed toward the blade 5 from the nozzle 41 after passing through the long tube 4, so that the blade 5 can be rinsed and impurities attached to the surface of the blade 5 can be washed off, thereby achieving self-cleaning of the blade 5, which is beneficial to the subsequent use of the blade 5.

[0050] Working principle: a person can push the vehicle body 1 by holding the handle 8, and manually rotate the threaded rod 17 to drive the lifting rod 10 to move, so that the handle 8 slides inside the sleeve 9 to adjust the height of the handle 8, so that the person can more easily control the entire vehicle body 1, which is more convenient. The driving device is used to rotate the blade 5 to cut the grass. While cutting, the vehicle body 1 is also moving. When the cut grass clippings are in the middle of the vehicle body 1, the motor 11 is started and drives the connecting rod 12 to rotate, so that the clamping box 15 moves, so that the clamping box 15 passes through the middle of the vehicle body 1 and contacts the ground, and then the motor 6 32 is started to drive the bidirectional threaded rod 30 to rotate, so that the threaded blocks 31 on both sides slide at the same time and approach each other. When the clamping boxes 15 are fitted together, the grass clippings can be collected inside the clamping box 15, and then the motor 11 is driven again The connecting rod 12 rotates to make the clamping box 15 rise and align with the top of the screen drum 14. At this time, the drum cover 38 does not close the screen drum 14. Then the two clamping boxes 15 are driven away from each other again. At the same time, the motor 5 29 is used to drive the two clamping boxes 15 to rotate in different directions at the same time, so that the clamping boxes 15 are tilted and the grass clippings inside are poured into the screen drum 14. When there are enough grass clippings inside the screen drum 14, the motor 2 13 is started to drive the rotating arm 34 to rotate 90 degrees, so that the screen drum 14 changes from longitudinal to transverse, and then the motor 7 36 is started to drive the gear 2 37 to rotate, so that the screen drum 14 rotates on the fixing ring 35. When the screen drum 14 rotates, the grass clippings will move with the screen drum 14 and form a falling effect, so that the soil and impurities in the grass clippings can be screened out from the sieve holes 33, thereby improving the purity and safety of the grass clippings as feed.

[0051] During the screening process, soil or impurities may clog the sieve holes 33. At this time, the sieve drum 14 can be restored to a vertical state, and the motor 7 36 can be used to drive the gear 2 37 to rotate, so that the sieve drum 14 can be rotated intermittently. When the sieve drum 14 stops, a row of sieve holes 33 coincides with the axis of multiple fixed disks 24. Then, the electric push rod 18 is started to drive the rectangular plate 20 to move, so that the scraper 25 extends into the sieve holes 33, and then the motor 4 23 is used to drive the turntable 40 to rotate. , so that the plurality of connecting rods 27 rotate, so that the slide bar 26 slides on the fixed plate 24, so that the plurality of scrapers 25 fit the hole wall of the sieve hole 33, and then the electric push rod 18 is used to move the scraper 25 from the sieve hole 33, so that the soil and impurities attached to the hole wall of the sieve hole 33 can be scraped out. However, since the angle of the scraper 25 is limited, a single scraping is not enough to scrape all the positions of the hole wall of the sieve hole 33. After the scraper 25 is moved out of the hole wall, the motor 3 19 is started to drive the plurality of The gear 21 rotates to adjust the angle of the scraper 25, and then the scraper 25 is extended into the sieve hole 33 again to scrape again. By repeating the above operation, the soil and impurities attached to the hole walls of all the sieve holes 33 can be scraped, thus avoiding the clogging of the sieve holes 33 and ensuring the use effect of the sieve drum 14. Thus, the anti-clogging grass clippings collection mechanism can be used to collect grass clippings during mowing, thus ensuring the cleanliness of the lawn, and the impurities and soil in the collected grass clippings can be filtered so that the grass clippings can be better used as feed. At the same time, the hole walls of the sieve holes 33 used to filter impurities can be cleaned to avoid the clogging of the sieve holes 33, and the recycling effect is good. The water in the water tank 2 is pumped out by the water pump 3, and then sprayed to the blade 5 from the nozzle 41 after passing through the long tube 4, so as to rinse the blade 5 and wash off the impurities attached to the surface of the blade 5, thereby realizing the self-cleaning of the blade 5, which is beneficial to the subsequent use of the blade 5.
