Technical Field
[0001] This utility model relates to the technical field of walk-behind lawnmowers, specifically a walk-behind lawnmower. Background Technology
[0002] Mowing is one of the main ways to utilize high-yield natural grasslands and artificial grasslands. Its purpose is to obtain fresh forage for livestock, or to process the forage into silage, semi-dry silage or hay that can be stored for a long time to feed livestock, thus affecting the botanical composition of the grass layer and the yield of regenerated grass.
[0003] A lawnmower is a mechanical tool used for trimming lawns, vegetation, etc. It consists of a cutter head, engine, wheels, a walking mechanism, blades, a handle, and a control unit. The cutter head is mounted on the wheels, and the engine is mounted on the cutter head. The blades are mounted on the engine's output shaft. The high-speed rotation of the blades by the engine greatly increases the speed, saving lawnmower workers' working time and reducing a significant amount of manpower.
[0004] When using existing lawnmowers, the cut grass is usually left on the surface of the lawn, making it difficult to collect the cut grass. (Under certain circumstances, it is necessary to collect the grass to ensure a clean and tidy environment, and some grass may contain insect eggs. If the grass is not collected, the insect eggs may multiply, which is not conducive to the growth of the grass.) In this case, a separate worker is needed to collect the weeds, which is very labor-intensive and resource-intensive. Utility Model Content

The mounting bracket 2... A rotating rod 20 is rotatably connected to the inner wall of the end of the 22. A sleeve 19 is fixedly connected to the surface of the rotating rod 20. A track groove 25 with the ends connected is opened on the surface of the sleeve 19. A sliding column 10 is slidably connected to the groove wall of the track groove 25. The end of the sliding column 10 away from the track groove 25 passes through the lower end face of the rotating plate 12. The surface of the sliding column 10 is fixedly connected to the groove wall of the through groove on the rotating plate 12. A motor 21 is provided on the upper surface of the mounting bracket 22. The surface of the motor 21 is connected to the surface of the rotating rod 20 by a belt drive.
[0026] More specifically, in this embodiment: during use, the motor 21 drives the rotating rod 20 to rotate, the rotating rod 20 further drives the sleeve 19 to rotate, the sleeve 19 rotates and causes the track groove 25 to rotate, which in turn causes the sliding column 10 to slide in the track groove 25, and then the rotating plate 12 swings around the rotating shaft 23 as the center, thereby driving the nozzle row 29 to swing. At the same time, the blower 11 blows air to clean up the cut grass, making the lawn clean and tidy after cleaning.
[0027] Example 3, based on the above examples, includes the following: a conveyor frame 9 is fixedly connected to the side of the base plate 18, and a storage box 8 is fixedly connected to the end of the conveyor frame 9 away from the base plate 18. The lower surface of the storage box 8 is fixedly connected to the upper surface of the base plate 18. A through mounting groove is provided on the side of the storage box 8. A door 4 is rotatably connected to the wall of the mounting groove. A handle 5 is fixedly connected to the surface of the door 4. An inclined block 6 is fixedly connected to the end of the conveyor frame 9 away from the base plate 18. A placement groove is provided on the side of the storage box 8. The wall of the placement groove is fixedly connected to the surface of the inclined block 6.
[0028] More specifically, in this embodiment: the cut grass is cleaned onto the conveyor frame 9 by the nozzle row 29, and then transported to the inclined block 6 by the conveyor frame 9. The grass then slides into the storage box 8 through the inclined surface of the inclined block 6, thereby realizing automatic cleaning of the cut grass, reducing the subsequent cleaning operation of the cut grass on the lawn, and further improving the practicality of this lawnmower.
[0029] Example 4, based on the above examples, includes the following: a sector gear 24 is fixedly connected to the surface of the rotating plate 12, a spur gear 7 is meshed with the tooth surface of the sector gear 24, a lever frame 27 is fixedly connected to the back tooth surface of the spur gear 7, and a sliding groove 26 is provided on the surface of the storage box 8, with the surface of the sliding groove 26 slidably connected to the surface of the lever frame 27.
[0030] More specifically, in this embodiment: the swing of the rotating plate 12 drives the sector gear 24 to swing around the rotating shaft 23, which in turn drives the spur gear 7 to move left and right, thereby causing the actuating frame 27 to slide in the sliding groove 26 and move left and right in the storage box 8. This further prevents the cut grass from piling up. By moving the actuating frame 27 left and right in the storage box 8, the grass entering the storage box 8 is prevented from piling up and affecting the storage capacity of the storage box 8.
[0031] Working principle: This hand-held lawnmower operates by following these steps:
[0032] In use, the lawnmower is pushed onto the lawn, and then motor 14 drives the mowing blade 15 to rotate, thus mowing the lawn. Motor 21 drives the rotating rod 20 to rotate, which in turn drives the sleeve 19 to rotate. The rotation of the sleeve 19 causes the track groove 25 to rotate, which in turn causes the sliding column 10 to slide within the track groove 25. Then, the rotating plate 12 swings around the rotating shaft 23, which in turn causes the nozzle row 29 to swing. At the same time, the blower 11 blows air to clean the mowed lawn. The grass is cleaned, making the lawn clean and tidy. The cut grass is collected on the conveyor frame 9 by the nozzle row 29, and then transported to the inclined block 6 by the conveyor frame 9. The grass then slides into the storage box 8 through the inclined surface of the inclined block 6. The swing of the rotating plate 12 drives the sector gear 24 to swing around the rotating shaft 23, which in turn drives the straight gear row 7 to move left and right. This causes the actuating frame 27 to slide in the sliding groove 26 and move left and right in the storage box 8, further preventing the cut grass from piling up.
[0033] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
