Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1 to 3This embodiment of a multi-functional lawnmower with a spraying function includes a frame 1. Two moving components 2 are provided on the left and right sides of the frame 1 to facilitate the movement of the lawnmower. An inner shell 3 is fixed inside the frame 1. A mowing component 4 is provided on the inner top wall of the inner shell 3, which penetrates the top wall of the inner shell 3 and performs mowing. A battery 5 is provided on the top of the inner shell 3. A digging device 6 is provided on the inner side of the frame 1, which extends to the outside of the frame 1 and can turn over the mud on the ground. A controller 7 is fixed on the top of the digging device 6. A primary liquid supply component 8 for spraying composting agent is provided on the digging device 6. A secondary liquid supply component 9 for spraying herbicide is provided on the top of the inner shell 3.

[0030] In addition, the frame 1 includes a base 101, and a protective cover 102 is fixed on the top of the base 101. The protective cover 102 is threaded with connecting bolts. This connection method can ensure good connection stability between the base 101 and the protective cover 102, and also facilitate the removal of the protective cover 102, thereby facilitating the maintenance and replacement of other devices inside the lawnmower. The protective cover 102 is fixed to the base 101 by connecting bolts.

[0031] In addition, each moving component 2 includes a connecting plate 201, which is fixed to the side wall of the base 101. A damper 202 is fixed to the bottom of the connecting plate 201. The damper 202 can absorb the vibration of the connecting spring 203, ensuring good shock absorption and providing a smoother ride for the lawnmower. The connecting spring 203 is sleeved on the outside of the damper 202. A wheel frame 204 is fixed to the bottom of the damper 202. The top and bottom of the connecting spring 203 abut against the connecting plate 201 and the wheel frame 204, respectively.

[0032] Understandably, the mowing assembly 4 includes a transmission unit 401, which is rotatably connected to the inner top wall of the inner shell 3. A flat bearing is fixed to the top of the transmission unit 401. The transmission unit 401 is rotatably connected to the inner top wall of the inner shell 3 via the flat bearing. A rolling rod 402 is rotatably connected to the outer surface of the transmission unit 401 via the bearing. A protective cover 403 is fixed to the outer surface of the rolling rod 402.

The grass-cutting blade 405 can cut tall grass. For grass that is growing low, only the secondary mowing section 408 needs to be used. The advantage of this design is that the mowing part of the secondary mowing section 408 is made of flexible material. The closer it is to the ground, the easier it is to hit stones. Using flexible material makes it safer when encountering stones. Multiple mowing blades 405 are fixed on the rolling rod 402. Multiple nozzles 406 are fixedly connected to the rolling rod 402. The multiple nozzles 406 are located above the multiple mowing blades 405. The transmission part 401 passes through the rolling rod 402. The secondary mowing section 408 is located on the outer surface of the rolling rod 402 and below the rolling rod 402.

[0033] It should be further explained that the transmission unit 401 includes an internal gear 4011 rotatably connected to the inner top wall of the inner shell 3. Multiple transmission rods 4012 are fixed to the inner top wall of the inner shell 3. Each transmission rod 4012 has a planetary gear 4013 rotatably connected to its outer surface via a bearing. The internal gear 4011 and the multiple planetary gears 4013 are internally meshed, and their rotation directions are the same. The multiple planetary gears 4013 are externally meshed with the driving gear 4015. Therefore, the driving gear... 4015 rotates in the opposite direction to the internal gear 4011. Multiple planetary gears 4013 mesh with the internal gear 4011. The top wall of the inner shell 3 is rotatably connected to the driving rod 4014 through the bearing. The outer surface of the driving rod 4014 is fixed with the driving gear 4015 that meshes with the multiple planetary gears 4013. The driving rod 4014 is rotatably connected to the rolling rod 402 through the bearing. The driving rod 4014 and the rolling rod 402 are connected. The inner side of the internal gear 4011 is fixed to the rolling rod 402.

[0034] It is known that a servo motor is fixed to the top of the inner shell 3. The servo motor provides power for the rotation of the pinion gear. The engagement of the pinion gear and the large gear drives the entire mowing assembly 4 to operate. One end of the servo motor output shaft is fixed to the pinion gear, and the other end of the servo motor output shaft is rotatably connected to the top of the inner shell 3 through a bearing. A large gear is fixed to the outer surface of the drive rod 4014. The pinion gear meshes with the large gear. The secondary mowing unit 408 includes a protective shell 4081 fixed to the outer surface of the drive rod 4014. The protective shell 4081 is hollow. The bottom of the protective shell 4081 is fixed with a bottom cover 4082 by bolts. The outer surface of the drive rod 4014 is engaged with a rotating roller 4083 located inside the protective shell 4081. Multiple transmission keys are fixed on the outer surface of the drive rod 4014. Multiple keyways are opened on the inner side of the rotating roller 4083. Multiple transmission keys extend into multiple keyways and are movably connected to the keyways. The top of the bottom cover 4082 abuts against the bottom of the rotating roller 4083. A grass-cutting rope 4084 extending out of the protective shell 4081 is fixed on the outer surface of the rotating roller 4083.

[0035] In this embodiment, a grip is fixed to the rear side of the base 101. The grip is fixed to the front and rear sides of the base 101. The grip helps the user push the mowing device, making it easy for the mowing device to move.

[0036] Please refer to it again. Figure 1 , Figure 4 and Figure 5In order to treat plant roots and stems, the soil-digging device 6 in this embodiment includes a support plate 601 fixed to the inner side wall of the frame 1. An electric push rod 602 is fixed to the bottom of the support plate 601. The electric push rod 602 can control the height of the mudguard 603, the drive unit 604 and the soil-turning unit 605. When it is not needed, it can be raised upwards and lowered when it is needed to turn the soil. The bottom of the electric push rod 602 is fixed to the mudguard 603. The bottom of the mudguard 603 is provided with the drive unit 604. The outer surface of the drive unit 604 is provided with the soil-turning unit 605.

[0037] In addition, the mudguard 603 is arc-shaped, which better fits the mud-turning part 605, thereby blocking the soil. The outer periphery of the mudguard 603 is arc-shaped. The drive part 604 includes two partitions 6041. The tops of the two partitions 6041 are fixed to the bottom of the mudguard 603. A drive motor 6042 is fixed to the rear side of the rear partition 6041. The drive motor 6042 can provide stable power for the rotation of the rotating rod 6043. The partitions 6041 can intercept the soil. A rotating rod 6043 that passes through the two partitions 6041 is fixed to one side of the output shaft of the drive motor 6042. The mud-turning part 605 includes a turning roller 60 that is fixedly connected to the outer surface of the rotating rod 6043. 51. Multiple turning blades 6052 are fixed on the outer surface of the turning roller 6051. When the turning roller 6051 rotates, it will drive the turning blades 6052 to rotate, thereby turning the soil and digging out the plant roots. Multiple fixing plates 6053 are fixed on the inner side of the turning roller 6051. Tension springs 6054 are fixed on the fixing plates 6053. Through the cooperation of the tension springs 6054 and the baffles 6055, a blocking structure can be formed to prevent soil from entering the stepped holes. Multiple stepped holes communicating with the inner cavity of the turning roller 6051 are opened on the outer surface of the turning roller 6051. A baffle 6055 is fixed on the side of the tension spring 6054 away from the fixing plates 6053. The baffle 6055 abuts against the stepped holes.

[0038] In addition, a stabilizing plate is fixed to the inner side of the base 101, and the output end of the electric push rod 602 passes through the stabilizing plate. The primary liquid supply assembly 8 includes a storage box fixed to the top of the stabilizing plate. The storage box is filled with a composting agent. Spraying the composting agent can accelerate the decomposition of plants. A primary liquid pump 801 is fixed to the top of the stabilizing plate. The primary liquid pump 801 can provide power for the flow of the agent. The input end of the primary liquid pump 801 is fixedly connected to the storage box. The output end of the primary liquid pump 801 is fixedly connected to the outlet pipe 802. The end of the outlet pipe 802 away from the primary liquid pump 801 is connected to the rotating rod 6043. The rotating rod 6043 and the outlet pipe 802 are rotatably connected through a bearing.

[0039] In addition, the secondary liquid supply assembly 9 includes a liquid storage tank 904 fixed to the inner bottom wall of the base 101, a secondary liquid pump 901 fixed to the top of the inner shell 3, and a drain pipe 903 and an inlet pipe 902 fixedly connected to both sides of the secondary liquid pump 901. The inlet pipe 902 extends into the liquid storage tank 904, which is filled with a pesticide, which can be a herbicide or a growth regulator, as long as it meets the specific use requirements. The end of the inlet pipe 902 away from the secondary liquid pump 901 is rotatably connected to the drive rod 4014 through a bearing.

[0040] In this embodiment, the end of the rotating rod 6043 away from the outlet pipe 802 and the inlet pipe 902, which is away from the secondary liquid pump 901, is rotatably connected to the drive rod 4014 through a sealed bearing, which can improve the sealing performance.

[0041] It is understandable that by combining the mowing component 4 and the digging device 6, multiple weeding modes can be achieved to meet various usage needs. At the same time, by combining the primary liquid supply component 8 and the secondary liquid supply component 9, the effectiveness of the device can be further improved.

[0042] All electrical components mentioned in this article are electrically connected to the controller and power supply. The control method of this invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply provided by the battery is also common knowledge in the art. Furthermore, this invention is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0043] The working principle of the above embodiments is as follows:

[0044] (1) When mowing, the servo motor drives the drive rod 4014 to rotate, and then the drive rod 4014 transmits the power synchronously to the transmission unit 401 and the secondary mowing unit 408. At this time, due to the action of the transmission unit 401, the rotation direction of the rolling rod 402 is opposite to that of the drive rod 4014, which causes the mowing blade 405 and the mowing rope 4084 to rotate in opposite directions, thereby breaking up the grass and making it easier to decompose and provide good nutrients for the lawn. While the mowing blade 405 is mowing, the primary liquid supply component 8 will continuously inject the agent into the rolling rod 402. At this time, the rotation of the rolling rod 402 will generate a large centrifugal force on the agent, and the agent will be sprayed out from the nozzle 406.

[0045] (2) When it is necessary to treat the plant roots, first start the electric push rod 602, and then the electric push rod 602 drives the mudguard 603 and the drive part 604 and the turning part 605 below it to move downward. Then start the drive motor 6042 to drive the rotating rod 6043 to rotate. At this time, the turning blade 6052 on the outer surface of the turning roller 6051 will turn the soil and pull out the plants and their roots. At the same time, the secondary liquid supply component 9 will continuously inject composting agent into the turning roller 6051. While turning the soil, the composting agent is sprayed to improve the plant decomposition efficiency.

[0046] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0047] 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.
