Description

Technical Field

[0001] This invention relates to the field of chainsaw mower technology, specifically to a garden intelligent rotary chainsaw mower. Background Technology

[0002] A lawn mower is a handheld tool used to cut weeds in lawns, gardens, pastures, and other places. Based on the power source, it can be divided into oil-powered and electric types.

[0003] In existing lawn mowers, a baffle is usually installed between the motor and the mowing head to prevent debris from entering the drive unit. However, as the lawn mower is used continuously, the debris flies around during operation, and the existing baffle is not enough to completely block the debris and other debris. The debris still enters the drive unit and affects its operation.

[0004] In addition, hay debris from the hay cutter is scattered everywhere and then accumulates on the ground. Some of the scattered hay will be on the working path of the hay cutter, and as the hay cutter runs, the hay debris accumulated on the ground will be rolled up by the running chainsaw hay cutter, thus entering the device through the gaps between the hay cutter parts and affecting the use of the hay cutter.

[0005] To address this issue, we propose a smart rotary chainsaw lawn mower for gardens. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a smart rotary chainsaw lawn mower for gardens, thereby solving the problems mentioned in the background section.

The turbulence component is driven by the anti-tangling and clogging component, and works with the anti-tangling and clogging component to prevent the cleaned hay debris from getting tangled inside the hay cutter and affecting the operation of the drive device in the hay cutter. The aerodynamic component includes a connecting sleeve fixedly installed on the bottom surface of the main body shell, a rotating sleeve rotatably installed at the bottom end of the connecting sleeve, and an aerodynamic fan connected to the internal thread at the bottom end of the rotating sleeve. The warning component is used in conjunction with the anti-tangling and clogging component and the turbulence component, and issues a warning when grass or debris inside the drive unit causes blockage and affects the rotation of the drive unit's output shaft.

[0008] Preferably, the anti-tangling and clogging component also includes a guide plate coaxially disposed above the drive fan, and a positioning plate coaxially disposed on the top of the guide plate. The positioning plate, the guide plate and the locking housing are arranged sequentially from top to bottom in the vertical direction and are all fixedly installed inside the connecting housing by bolts.

[0009] Preferably, the output shaft passes through the center of the positioning plate, the guide plate, the locking housing, the drive fan, and the limiting plate from top to bottom, and the output shaft is inserted and fixedly installed at the center of the drive fan. The limiting plate is rotatably installed inside the main housing, and the protective housing is fixedly installed on the outer surface of the main housing.

[0010] Preferably, the chainsaw body is symmetrically arranged inside the main body shell, and both ends of the chainsaw body penetrate through and extend to the outside of the main body shell. The chainsaw body is composed of a steel plate and a chain that is slidably arranged on the outer peripheral surface of the steel plate. The steel plate is fixedly installed inside the main body shell. A meshing gear is fixedly installed on the outside of the output shaft. The meshing gear is located at the center of the chain and meshes with the chain.

[0011] Preferably, a flow channel is provided through the top of the locking shell around the center, and a flow channel is provided inside the flow plate around the center, with the flow channel and the flow channel communicating with each other.

[0012] Preferably, the turbulence assembly further includes a drive gear fixedly connected to the outer surface of the bottom end of the output shaft, positioning buckles symmetrically fixedly installed on both sides of the outer surface of the top end of the turbulence fan, and pressing buckles symmetrically fixedly installed on the outer surfaces of both sides of the bottom end of the rotating sleeve.

[0013] Preferably, the positioning buckle and the pressing buckle are matched and adapted, and a connecting groove is opened in the center of the deflector fan, and the drive gear is matched and adapted to the connecting groove of the deflector fan.

[0014] Preferably, the warning component includes a speed sensor fixedly installed outside the output shaft, a warning device fixedly installed on the outer surface of the connecting housing, and a circumferential array of barrier bars arranged on the bottom surface of the positioning plate.

[0015] Preferably, each set of barrier bars consists of three barrier links. The outer surface of the bottom end of the barrier link located at the center is symmetrically provided with small links, and the two barrier links on both sides are fixedly connected to the side surface of the barrier link near the center.

[0016] Preferably, the barrier bars are all installed inside the flow channels opened in the guide plates at the corresponding positions.

[0017] Compared with the prior art, the present invention provides a garden intelligent rotary chainsaw lawn mower, which has the following beneficial effects: By using a combined drive fan and a spoiler fan, the hay debris generated after cutting near the mower is blown away, preventing it from accumulating near the chainsaw body and thus avoiding its entry into the mower. The timely removal of hay debris prevents its accumulation near the chainsaw, allowing operators to continue mowing without frequent shutdowns, significantly improving work efficiency. This is especially beneficial for large-area lawn mowing, saving considerable time and labor costs. Furthermore, hay debris entering the mower can become entangled in rotating parts such as chains, gears, or the output shaft of the drive unit, increasing friction and resistance and potentially causing jamming or damage. Preventing hay debris from entering the mower reduces the probability of malfunctions and extends the equipment's lifespan.

[0018] The drive fan, deflector, and positioning plate are designed to direct airflow into the drive unit during operation, thereby cooling the drive unit. Effective airflow cooling keeps the drive unit operating within a suitable temperature range, slows down the aging process of components, and extends the service life of the entire drive unit.

[0019] The barrier bar located at the bottom of the positioning plate can further block debris from entering the device, thus preventing debris and other impurities from entering the device and affecting the use of the drive device.

[0020] By locking the housing, deflector, and positioning plate, the position of the drive fan is restricted. At the same time, the plug-in installation of the drive fan and the limiting plate allows the drive fan to rotate stably. In addition, the locking housing, deflector, and positioning plate, which are fixed by bolts, can be quickly disassembled and installed, thus enabling quick installation and disassembly of the lawn mower for easy subsequent maintenance.

[0021] By using a spoiler fan, ground debris is blown away, preventing it from accumulating at the bottom of the mower and getting caught in the chainsaw, thus affecting its operation. Furthermore, the threaded connection between the spoiler fan and the rotating sleeve is in the same direction as the spoiler fan's rotation, preventing the connection between the spoiler fan and the rotating sleeve from failing during rotation. In addition, the positioning and pressing buckles facilitate the positioning of the spoiler fan, further preventing it from becoming loose. Attached Figure Description

[0024] 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.

[0025] Embodiments of the present invention Please see Figures 1 to 3 and Figures 5 to 10A garden intelligent rotary chainsaw lawn mower includes a main body 11, a handle 12 fixedly installed on the top of the main body 11, a drive device 13 fixedly installed on the bottom of the main body 11, a protective shell 14 provided on the bottom of the drive device 13, and also includes an anti-tangling and blocking component, a turbulence component and a warning component disposed below the drive device 13.

[0026] The anti-entanglement and clogging component includes a connecting housing 21 fixedly connected to the outside of the bottom end of the drive device 13, a locking housing 22 fitted to the bottom end of the connecting housing 21, a main housing 23 fixedly installed at the bottom end of the locking housing 22 by bolts, an output shaft 24 fixedly installed at the bottom output shaft end of the drive device 13 by a coupling, a chainsaw body 25 provided on the outside of the bottom end of the output shaft 24, a limit plate 26 rotatably installed inside the top of the main housing 23, and a drive fan 27 inserted into the top of the limit plate 26.

[0027] The anti-tangling and clogging assembly also includes a guide plate 28 coaxially disposed above the drive fan 27. A positioning plate 29 is coaxially disposed on the top of the guide plate 28. The positioning plate 29, the guide plate 28 and the locking housing 22 are arranged sequentially from top to bottom in the vertical direction and are all fixedly installed inside the connecting housing 21 by bolts.

[0028] The output shaft 24 passes through the center of the positioning plate 29, the guide plate 28, the locking shell 22, the drive fan 27 and the limiting plate 26 from top to bottom. The output shaft 24 is inserted and fixedly installed at the center of the drive fan 27. The limiting plate 26 is rotatably installed inside the main shell 23. The protective shell 14 is fixedly installed on the outer surface of the main shell 23.

[0029] The chainsaw body 25 is symmetrically arranged inside the main body shell 23, and both ends of the chainsaw body 25 extend through and out of the main body shell 23. The chainsaw body 25 is composed of a steel plate and a chain that is slidably arranged on the outer circumferential surface of the steel plate. The steel plate is fixedly installed inside the main body shell 23. A meshing gear is fixedly installed on the outside of the output shaft 24. The meshing gear is located at the center of the chain and meshes with the chain.

[0030] The top of the locking housing 22 is provided with a flow channel through the center, and the inside of the flow plate 28 is provided with a flow channel through the center. The flow channel and the flow channel are connected.

[0031] In an alternative embodiment, see [reference] Figure 1The main body 11, handle 12 and drive device 13 are all existing technologies, so they will not be described in detail here. The main body 11 and handle 12 are convenient for holding and controlling the movement of the lawn mower. The handle 12 is equipped with a switch for opening and closing the drive device 13. The drive device 13 is an existing drive motor, and the output shaft end of the drive motor is located at the bottom of the drive device 13.

[0032] In an alternative embodiment, see [reference] Figure 2 The protective housing 14 is used to apply a protective device to the outside of the chainsaw body 25 to prevent accidental injury to the user when the chainsaw body 25 is started.

[0033] In an alternative embodiment, see [reference] Figure 5 , Figure 6 , Figure 7 and Figure 8 When the above-mentioned grass cutter is used, the drive device 13 is started by the switch on the handle 12, and the output shaft 24 is fixedly connected to the bottom output shaft of the drive device 13. Through the meshing gear fixedly installed on the outside of the output shaft 24, the chain meshing with it is driven to rotate cyclically on the surface of the steel plate. The user can control the position of the main body 11 of the equipment to achieve grass cutting operations in multiple positions.

[0034] In an alternative embodiment, see [reference] Figure 7 and Figure 8 When the drive device 13 drives the output shaft 24 to rotate, the output rotation causes the drive fan 27, which is plugged into it, to rotate. The drive fan 27 drives the limiting plate 26, which is plugged into it, to rotate synchronously inside the main body shell 23. The airflow generated by the rotation of the drive fan 27 passes through the guide groove that runs around the center of the top of the locking shell 22 and the flow groove that runs around the center inside the guide plate 28, blowing the airflow generated by the rotation of the drive fan 27 upward into the drive device 13, thereby assisting in cooling the drive device 13.

[0035] It should be noted that during the above process, the chainsaw body 25 cuts the hay while rotating, completing the hay cutting process. As the chainsaw body 25 rotates at high speed, the cut hay debris may enter the hay cutter with the airflow and become entangled on the outside of the output shaft of the drive device 13, thus affecting the operation of the drive device 13. In specific implementation, a through slot is provided on the outside of the top of the main body shell 23. When the drive fan 27 rotates and guides the airflow, the airflow enters the interior of the main body shell 23 through the through slot, and the main body shell 23 blocks most of the debris on the outside of the main body shell 23.

[0036] Furthermore, the guide plate 28 and positioning plate 29 located above the drive fan 27 will further block the debris, preventing the grass debris from entering the drive unit 13 and thus affecting the operation of the drive unit 13.

[0037] In an alternative embodiment, see [reference] Figure 6 , Figure 7 , Figure 8 and Figure 9 The locking housing 22 and the main housing 23 are fixed together by bolts. After use, the locking housing 22 and the main housing 23 can be disassembled by removing the bolts, and the bolts between the locking housing 22, the guide plate 28 and the positioning plate 29 can be removed, thereby disassembling the parts inside the housing 21, thus enabling the quick disassembly and assembly of the complete lawn mower, which is convenient for subsequent maintenance.

[0038] Further embodiments Please see Figures 3 to 7 and Figure 10 The garden intelligent rotary chainsaw mower also includes a turbulence component, which is driven by an anti-tangling and anti-clogging component. In conjunction with the anti-tangling and anti-clogging component, it prevents the cleaned grass debris from getting tangled inside the mower and affecting the operation of the drive unit 13 in the mower.

[0039] The aerodynamic component includes a connecting sleeve 31 fixedly installed on the bottom surface of the main body shell 23, a rotating sleeve 32 rotatably installed at the bottom end of the connecting sleeve 31, and an aerodynamic fan 33 connected to the internal thread at the bottom end of the rotating sleeve 32.

[0040] The turbulence assembly also includes a drive gear 34 fixedly connected to the outer surface of the bottom end of the output shaft 24, positioning buckles 35 symmetrically fixedly installed on both sides of the outer surface of the top end of the turbulence fan 33, and pressing buckles 36 symmetrically fixedly installed on the outer surfaces of both sides of the bottom end of the rotating sleeve 32.

[0041] The positioning buckle 35 and the pressing buckle 36 are engaged and adapted to each other. A connecting groove is provided in the center of the interior of the deflector fan 33, and the drive gear 34 is inserted and adapted to the connecting groove of the deflector fan 33.

[0042] In an alternative embodiment, see [reference] Figure 5 , Figure 6 , Figure 7 and Figure 10 Specifically, when the output shaft 24 rotates, the drive gear 34 fixedly connected to its bottom end will rotate synchronously, and the baffle fan 33 meshing with it will rotate synchronously, stirring the airflow at the bottom of the grass cutter, preventing the cut grass from accumulating at the bottom of the grass cutter and getting tangled on the chainsaw body 25 as the grass cutter runs, thus affecting the operation of the chainsaw body 25.

[0043] It should be noted that when the hay cutter is started, the drive fan 27 and the deflector fan 33 operate synchronously to further prevent hay debris from accumulating at the bottom of the hay cutter during operation, and from getting tangled in the chainsaw body 25 or entering the drive unit 13, thereby affecting the operation of the chainsaw body 25 and the drive unit 13.

[0044] It should also be noted that the airflow generated when the deflector fan 33 rotates is in a direction away from the chain saw body 25 of the mower, thereby preventing the hay debris accumulated on the ground from gathering at the mower as it runs, and further preventing hay debris from entering the mower's interior.

[0045] In an alternative embodiment, see [reference] Figure 3 and Figure 4 Due to the threaded connection between the rotating sleeve 32 and the spoiler 33, during the actual installation, the spoiler 33 is threadedly installed inside the rotating sleeve 32. After the spoiler 33 and the rotating sleeve 32 are threadedly installed, the positioning buckle 35 will be in a mutually engaging state with the pressing buckle 36.

[0046] It should be noted that the rotation direction of the spoiler fan 33 is the same as the helical direction of its thread. Therefore, the rotation of the spoiler fan 33 will synchronously drive the rotating sleeve 32 to rotate at the bottom of the connecting sleeve 31, further preventing the threaded connection between the spoiler fan 33 and the rotating sleeve 32 from failing.

[0047] It should also be noted that the snap-fit ​​installation between the positioning buckle 35 and the pressing buckle 36 further prevents the connection between the deflector fan 33 and the rotating sleeve 32 from failing.

[0048] In an alternative embodiment, see [reference] Figure 4 When disassembling the spoiler 33, the user can press down on the buckle 36 with their hand to disengage the buckle 36 from the positioning buckle 35. Then, the spoiler 33 can be quickly disassembled by rotating it in the opposite direction, which facilitates subsequent maintenance work.

[0049] It should be noted that when disassembling the spoiler fan 33 by rotating it in the opposite direction, the user needs to hold the rotating sleeve 32 with one hand to prevent the rotating sleeve 32 from rotating synchronously with the spoiler fan 33.

[0050] Further embodiments Please see Figure 2 and Figures 6 to 10 The garden intelligent rotary chainsaw lawn mower also includes a warning component, which is used in conjunction with the anti-tangling and anti-clogging component and the turbulence component, and issues a warning when grass debris blocks the output shaft of the drive unit 13 and affects its rotation.

[0051] The warning assembly includes a speed sensor 41 fixedly installed outside the output shaft 24, a warning device 42 fixedly installed on the outer surface of the housing 21, and a circumferential array of barrier bars 43 arranged on the bottom surface of the positioning plate 29.

[0052] Each set of barrier bars 43 consists of three barrier links. The outer surface of the bottom end of the barrier link located at the center is symmetrically provided with small links. The two barrier links on both sides are fixedly connected to the side surface of the barrier link near the center.

[0053] The barrier bars 43 are all located inside the flow channels opened in the corresponding guide plates 28.

[0054] In an alternative embodiment, see [reference] Figure 6 The speed sensor 41 is an existing product, and can optionally be an SPI3 series metal thread type magnetoelectric speed sensor 41, which specifically senses the rotation speed of the output shaft 24, and then monitors the output shaft speed of the output shaft 24 and the output shaft speed of the drive device 13 in real time.

[0055] In an alternative embodiment, see [reference] Figure 2 The warning device 42 is specifically an audible and visual alarm. The warning device 42 is driven by the speed sensor 41. The warning device 42 has a built-in signal receiving device. When the speed of the drive shaft and the output shaft of the drive device 13 is lower than the set threshold, the speed sensor 41 sends a signal to cause the warning device 42 to issue an audible and visual alarm, thereby reminding the user that debris has entered the lawn mower or that the drive device 13 itself has malfunctioned and needs to be repaired.

[0056] In an alternative embodiment, see [reference] Figure 8 , Figure 9 and Figure 10 Since the barrier bars 43 are all set inside the flow channels opened in the corresponding guide plates 28, and each set of barrier bars 43 consists of three obstructing links, the outer surface of the bottom end of the obstructing link located in the center is symmetrically provided with small links, and the two obstructing links on both sides are fixedly connected with small links on the side surface of the obstructing link near the center. Therefore, when grass debris and other debris pass through the guide fan and the positioning plate 29, they will be further blocked by the barrier bars 43, preventing the debris from entering the interior of the drive device 13 and causing damage to the drive device 13.

[0057] It should be noted that, in this document, relational terms such as "first" and "second" are used merely 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.

[0058] 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, the scope of which is defined by the appended claims and their equivalents.
