Description

Technical Field

[0001] The invention relates to the technical field of gardening equipment, in particular to a multifunctional gardening lawn mower. Background Art

[0002] A lawn mower is composed of a cutter disc, an engine, a traveling wheel, a traveling mechanism, a blade, an armrest, and a control part. The cutter disc is mounted on the traveling wheel, the engine is mounted on the cutter disc, and the blade is mounted on the output shaft of the engine. The blade uses the high-speed rotation of the engine to cut weeds and is often used in the field of agricultural weeding.

[0003] Traditional lawn mowers only have the function of mowing, and cannot collect the cut grass. Therefore, another worker is required to do the cleaning work, resulting in low mowing efficiency. The Chinese patent document with announcement number CN204518478U discloses a multifunctional lawn mower for gardening, including a main body, the main body is composed of a self-cooling chassis arranged on the top of the main body and a rear cover plate arranged on one side of the main body, a Y355 motor is arranged inside the self-cooling chassis, and the Y355 motor is embedded in the self-cooling chassis, and a transmission shaft is arranged inside the Y355 motor, and the transmission shaft is arranged through the Y355 motor. This solution sets up a grass collection box, and the suction generated by the rotation of the cutting blade transports the harvested weeds to the grass collection box for processing and recycling. However, in actual use, when there is a foreign object underground, the movement direction of the entire lawn mower needs to be changed. If the mowing surface directly contacts the foreign object, the entire lawn mower needs to be moved manually, and the mowing smoothness is poor. In addition, lawns are usually planted with shrubs. When the lawn mower in the above solution and other lawn mowers on the market are used, it is easy to mistake shrubs for weeds and directly roll them into the lawn mower for cutting without corresponding protective measures. Based on this problem, we propose a multifunctional garden lawn mower. Summary of the invention

[0019] 2. The multifunctional garden lawn mower disclosed in the present invention, when the garden lawn mower is mowing, if it touches an abnormally protruding foreign object on the ground, it will be affected by the elastic force of the rear spring and the front spring, and will push the cutoff plate to change the specified angle and roll over the foreign object, thereby preventing the cutting mouth from being stuck in place by the foreign object, thereby ensuring the smooth operation of the entire lawn mower.

[0020] 3. The multifunctional garden lawn mower disclosed in the present invention drives the cut-off plate to cover the mowing groove by means of a gear structure transmission structure. If some shrubs are sucked in, the inner tooth blade on the cut-off plate cooperates with the outer tooth blade to quickly cut off the sucked-in shrubs and block the mowing groove, blocking the flow direction of the negative pressure airflow, effectively preventing the shrubs from being sucked into the lawn mower and being mistaken for weeds and cut off by the lawn mower, thereby protecting the shrubs.

The DC motor 51 is arranged on the left front side of the upper surface of the conveying shell 6.

The upper side of the air inlet pipe of the fan 55 is connected in series with an air filter 14.

[0035] The working principle of the multifunctional garden lawn mower provided by the present invention is as follows:

[0036] When the garden lawn mower is needed, the weed collecting belt is tied to the lower side of the discharge hopper 9, the DC motor 51 is turned on, the output shaft of the DC motor 51 is rotated, and then the driving pulley 52 is driven to rotate, and then the rotating shaft 701 is driven to rotate through the belt 54 and the driven pulley 53, and then the mowing blade 7 is rotated, and at the same time, the control switch group 11 is adjusted and the fan 55 is turned on, and the fan 55 forms a negative pressure, and the external airflow is circulated at high speed to the inside of the arc-shaped shell 1 through the mowing groove 2 and the transverse groove, and then the airflow flows into the conveying shell 6, and then the push handle 10 can be manually operated to push the entire mowing machine through the driven wheel 12 and the steering wheel 13. The lawn mower is in motion. When the weeds extend into the mowing groove 2, they are stretched by the negative pressure airflow, and then the excess weeds are cut by the high-speed rotating mowing blade 7. Then, the weeds are guided by the negative pressure airflow and the rotating spiral blade 703 to enter the conveying shell 6, and then fall on the belt conveyor 8. After being transported by the belt conveyor 8, they fall into the discharge hopper 9. The guided airflow is discharged from the air filter 14 to the outside of the lawn mower. The weeds are filtered by the air filter 14 and fall into the weed collection belt under the action of inertia. When the garden lawn mower moves to the front of the bushes, it can be manually regulated and controlled. The switch group 11, the stepper motor 39 is running, the output shaft of the stepper motor 39 rotates a specified number of times, thereby driving the gear 38 to rotate a specified number of times, and then driving the fixed plate 37 to change the specified angle around the rotating shaft 701 through the teeth. During this period, the cut-off plate 4 changes the specified angle around the rotating shaft 701, and the lower side of the curved surface of the cut-off plate 4 will block the mowing groove 2, blocking the negative pressure airflow from flowing into the interior of the curved housing 1. If part of the shrubs have been sucked into the interior of the curved housing 1, during the period when the lower side of the curved surface of the cut-off plate 4 blocks the mowing groove 2, the inner tooth blade 15 cooperates with the outer tooth blade to suck part of the shrubs. Direct cutting can prevent excessive damage to the bushes. During normal use of the garden lawn mower, the stepper motor 39 is turned off. At this time, the stepper motor 39 is powered off and loses its power source, and there is no self-locking effect. At this time, it is affected by the elastic force of the rear spring 34 and the front spring 35, and the arc-shaped slider 36 is supported in both directions to ensure the stability of the fixed plate 37. If the transverse groove touches an abnormally protruding foreign object on the ground, it will push the cutting plate 4 to change the specified angle and roll over the foreign object to prevent the cutting mouth from being stuck by the foreign object. After passing the foreign object, the cutting plate 4 is affected by the elastic force to perform a reset operation. When facing an uneven ground, the lawn mower can also smoothly perform mowing operations.
