DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-5 As shown, a technical solution provided by the utility model:

[0024] The garden pruning device comprises a top plate 1, a frame 2 is symmetrically arranged at the bottom ends of both sides of the top plate 1, a lifting frame 3 is movably installed below the bottom end of the top plate 1, a motor 4 is arranged at the top end of the lifting frame 3, a cutting knife 5 is fixedly installed on the output shaft of the motor 4 through the lifting frame 3, a first transmission shell 6, the first transmission shell 6 is arranged on one side of the middle part of the top end of the top plate 1, a handle 7 is arranged on the side of the top plate 1 close to the first transmission shell 6, a lifting mechanism is arranged between the first transmission shell 6 and the handle 7, the lifting mechanism comprises a hanger 10, a hand crank 11 and a connecting shaft 12, the hanger 10 is fixedly connected to the middle part of the handle 7, the connecting shaft 12 is movably installed in the middle part of the hanger 10, the hand crank 11 is fixedly installed on the end of the connecting shaft 12 away from the top plate 1, and the lifting mechanism comprises a hanger 10, a hand crank 11 and a connecting shaft 12. The mechanism also includes a first bevel gear 13, a second bevel gear 14, a screw 15 and a sleeve 16. A mounting frame 17 is fixedly installed on the inner top of the first transmission housing 6. The other end of the connecting shaft 12 passes through the first transmission housing 6 and the mounting frame 17 to fix the first bevel gear 13. A frame 18 is fixedly installed just above the top of the lifting frame 3. A sleeve 16 is fixedly installed on the top of the frame 18. A screw 15 threadedly connected to the sleeve 16 is provided at the bottom end of the second bevel gear 14. Guide rods 19 are provided at the four corners of the top of the lifting frame 3. Guide grooves 20 movably connected to the guide rods 19 are provided at the four corners of the middle of the top plate 1. Axle frames 26 are provided on both sides of the bottom ends of the two frames 2, and walking wheels 27 are movably installed on the inner side of the axle frames 26.

[0025] In this embodiment, when using the device to trim the garden lawn, the device is pushed onto the lawn, and then the hand crank 11 is shaken. The hand crank 11 drives the first bevel gear 13 to rotate through the connecting shaft 12, and the first bevel gear 13 drives the screw rod 15 to rotate through the second bevel gear 14. When the screw rod 15 rotates, since the guide rods 19 at the four corners of the lifting frame 3 are guided by the guide groove 20, the sleeve 16 can drop straight down, thereby driving the cutting knife 5 at the bottom end of the lifting frame 3 to drop to the required height, and then starting the motor 4. The motor 4 controls the cutting knife 5 to cut the lawn. In this way, the device can adjust the cutting knife 5 to different heights according to needs, so as to cut the lawn into different heights according to needs.

[0026] like Figure 3 and Figure 5 As shown, a second transmission shell 8 is arranged between the lifting frame 3 and the motor 4, a sealing cover 9 is arranged on the side of the second transmission shell 8 close to the handle 7, and a blowing mechanism is arranged between the sealing cover 9 and the second transmission shell 8, and the blowing mechanism includes a fan blade 21, and the fan blade 21 is arranged at the inner middle part of the sealing cover 9 through a rotating shaft, and a small gear 22 is fixedly installed in the middle part of the rotating shaft, and a large gear 23 is fixedly installed in the middle part of the output shaft of the motor 4, and the large gear 23 is movably connected with the small gear 22 through a toothed belt. The blowing mechanism also includes a filter screen 24 and a nozzle 25, and the filter screen 24 is arranged at the middle part of the top end of the sealing cover 9, and one end of the nozzle 25 is connected with the sealing cover 9. When the cutting knife 5 cuts, weeds will splash, and when the fan blade 21 rotates, air enters the sealing cover 9 from the outside. The use of the filter screen 24 can prevent weeds in the air from entering, causing the fan blade 21 to be entangled, and the other end of the nozzle 25 is arranged on the inner side below the bottom end of the lifting frame 3;

[0027] In this embodiment, when the motor 4 is started, the transmission shaft of the motor 4 will drive the large gear 23 to rotate, and the large gear 23 will drive the small gear 22 inside the sealing cover 9 to rotate synchronously through the toothed belt. When the small gear 22 rotates, the fan blades 21 are driven to rotate at high speed through the rotating shaft. After the fan blades 21 rotate at high speed, external air is sucked in from the top of the sealing cover 9, and the air is compressed into the nozzle 25. The weeds remaining on the surface of the cutting knife 5 during cutting are cleaned up through the nozzle 25. In this way, automatic cleaning can be achieved, and the motor 4 can drive the cutting knife 5 and the fan blades 21 at the same time, further achieving the purpose of energy saving.

[0028] Working principle: When using the device to trim the garden lawn, push the device onto the lawn, and then shake the hand crank 11. The hand crank 11 drives the first bevel gear 13 to rotate through the connecting shaft 12, and the first bevel gear 13 drives the screw rod 15 to rotate through the second bevel gear 14. When the screw rod 15 rotates, since the guide rods 19 at the four corners of the lifting frame 3 are guided by the guide groove 20, the sleeve 16 can drop straight down, thereby driving the cutting knife 5 at the bottom end of the lifting frame 3 to drop to the required height, and then start the motor 4. The motor 4 controls the cutting knife 5 to cut the lawn. When the motor 4 is started, the transmission shaft of the motor 4 will drive the large gear 23 to rotate, and the large gear 23 drives the small gear 22 inside the sealing cover 9 to rotate synchronously through the toothed belt. When the small gear 22 rotates, the fan blade 21 is driven to rotate at a high speed through the rotating shaft. After the fan blade 21 rotates at a high speed, the external air is sucked in from the top of the sealing cover 9, and the air is compressed into the nozzle 25, and the weeds remaining on the surface of the cutting knife 5 during cutting are cleaned up through the nozzle 25.

[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
