Description

Technical Field

[0001] The present invention relates to the technical field of garden greening maintenance, in particular to a lawn mowing device used for garden greening maintenance. Background Art

[0002] Landscaping refers to the practice of planting vegetation and designing landscapes in cities, villages, or specific areas through scientific and rational means to improve environmental quality, beautify the living environment, protect the natural ecology, and enhance people's quality of life. To maintain and enhance landscape quality, extend plant life, and achieve ecological benefits, landscaping maintenance is often necessary, and mowing is a very important part of this process, which is currently mostly done using lawn mowers.

[0003] Patent publication number CN221178470U discloses a lawn mower comprising a main body, a push rod rotatably mounted on the main body, a locking device disposed between the main body and the fixed end of the push rod, adapted to limit the relative angle between the push rod and the main body and having at least two gears, and a height adjustment handle disposed at the armrest end of the push rod and transmitted to the locking device via a pulling member, adapted to release the locking device from the restricted state. The height adjustment handle, fixed to the armrest end of the push rod, controls the locking device at the fixed end of the push rod armrest, making the entire height adjustment process more convenient for the user without the need for auxiliary equipment or bending over.

[0004] However, the above-mentioned lawn mower still has the following problems during actual use:

[0005] Traditional lawn mowers generally use a single grass bag design, whose primary function is to collect grass clippings in real time during operation, preventing secondary scattering of grass clippings. However, this design has a significant drawback: the grass bag has a fixed capacity, requiring periodic shutdown for manual emptying. Specifically, when grass clippings reach the upper limit of the bag, the operator must first release the grass bag's securing mechanism, then remove the filled grass bag, empty the grass clippings, and finally reinstall a new bag or clean and reuse the old one.

[0006] This process not only creates additional labor (a single operation can take 3-5 minutes or even longer), but more importantly, if the machine is in continuous operation, energy is continuously wasted. If it is temporarily shut down, the subsequent restart requires repeating the ignition process. When working with large lawns (such as commercial lawns or municipal projects), frequent loading and unloading operations can cause the mower to fall into a "start-stop cycle": the startup phase requires preheating the engine (gasoline engines require a certain amount of idling time, and diesel engines may produce higher emissions), while restarting after shutting down the engine faces the inconvenience of cold engine ignition delay. Summary of the Invention

[0007] In view of the deficiencies of the prior art, the present invention provides a lawn mowing device for landscaping maintenance, which can replace the collection component more quickly, thereby reducing the number of equipment shutdowns or standby time.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This lawn mower, used for landscaping and maintenance, features modular assembly of the collection unit through the coordination of support components (vertical plates, slide bars) and limit components (U-shaped blocks, elastic components). Operators simply pull a lever to unlock the insertion rod, allowing for removal and replacement of the collection unit in just 30 seconds. This eliminates the complex steps required to remove traditional grass bag systems and significantly reduces downtime.

[0020] 2. This type of lawn mower, used for landscaping and maintenance, features multiple infrared sensors within its collection module. These sensors monitor the accumulation of grass clippings by measuring the obstruction between the transmitter and receiver. As grass clippings cover the sensors at varying heights, an audible and visual alarm emits green, orange, and red warning lights (green for normal operation, red for a full load). This helps operators accurately determine when to replace the mower, avoiding premature downtime and grass clipping overflow.

[0021] 3. This type of lawn mower used for landscaping maintenance has a switch assembly (insert block, circular frame, and elastic conductive sheet) that automatically closes the circuit and activates the monitoring mechanism when the collection assembly is installed. When removed, the circuit automatically disconnects, preventing the risk of accidental contact or short circuits. This design eliminates the need for manual power on / off, improving safety and ease of operation.

[0022] 4. This type of lawn mowing equipment used for landscaping maintenance uses elastic components (anti-drop rod, insertion rod, and push spring) to ensure that the collection assembly is firmly fixed to the slide bar during operation, preventing loosening due to vibration or impact of grass clippings. At the same time, the dual limit design of the anti-drop plate and support plate keeps the collection assembly horizontal and stable, preventing it from tilting and leaking grass.

[0023] 5. This type of lawn mower, used for landscaping and maintenance, features a collection component that uses a combination of breathable cloth and accordion panels. The breathable cloth allows airflow to reduce internal pressure and prevent grass clippings from clogging. The accordion panels can be extended laterally as the amount of grass increases, temporarily expanding the collection space and delaying full load time, adapting to different operating scenarios.

[0024] 6. This type of lawn mowing equipment used in landscaping maintenance has a design where, when the first module is fully loaded, the second module automatically slides down along a slide bar to the working position. The operator can switch to the standby module without stopping the machine, enabling continuous operation. This design is particularly suitable for large lawns, reducing energy waste and cold restart problems caused by "start-stop cycles." BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] See also Figures 1-11 The U-shaped frame 10 is aligned with the grass outlet pipe 13, and the bottom surface of the U-shaped frame 10 is fixedly connected to the upper surface of the extension plate 15. The extension plate 15 and the U-shaped frame 10 are connected to the end away from the lawn mower body 1. The upper end of the support assembly is connected to four limit assemblies, and the four limit assemblies are divided into two groups. The two groups of limit assemblies are respectively connected to the upper strip 18 and the lower strip 30. One side of the upper strip 18 and the lower strip 30 is connected to the collecting assembly. Several monitoring mechanisms are connected inside the collecting assembly. The collecting assembly and the several monitoring mechanisms are all located above the support assembly. A switch assembly that can control the opening and closing of several monitoring mechanisms is connected between the lower strip 30 and the extension plate 15. The upper strip 18, the lower strip 30, the collecting assembly, the monitoring mechanism and the four limit assemblies form a module, and the total number of modules is several.

[0039] More specifically, the above-mentioned lawn mower body 1 and grass discharge pipe 13 are both existing mature technologies, and the lawn mower body 1 also includes a power component (engine), a cutting component (cutter disc and blades), a walking component (wheels), a steel frame, a blade guard, a power supply, a control main board and a fuel tank (see Figures 1 to 3 ), which will not be described in detail here.

[0040] As a preferred solution of the present invention, the support assembly includes a vertical plate 5, a support plate 6, an anti-fall plate 21, two support blocks 16 and two sliding rods 17. One side of the lower end of the vertical plate 5 is fixedly connected to the end of the U-shaped frame 10 away from the lawn mower body 1, and the two sides of the upper end of the vertical plate 5 are respectively fixedly connected to one end of the two support blocks 16. The bottom surfaces of the other ends of the two support blocks 16 are respectively fixedly connected to the upper ends of the two sliding rods 17. The lower ends of the two sliding rods 17 are respectively fixedly connected to the two sides of the upper surface of the support plate 6. The end of the support plate 6 close to the sliding rod 17 is fixedly connected to the end of the extension plate 15 away from the lawn mower body 1. One side of the anti-fall plate 21 is fixedly connected to the side of the vertical plate 5 away from the U-shaped frame 10. The anti-fall plate 21 and the support plate 6 are respectively against the upper strip 18 and the lower strip 30, and the support plate 6 is also connected to the switch assembly.

[0041] More specifically, by providing a support assembly, support can be provided for the switch assembly and several collection assemblies to avoid contact with the ground due to weight, thereby preventing increased wear.

[0042] As a preferred solution of the present invention, the switch assembly includes an alignment plate 27, two circular frames 28, two plug blocks 29 and four elastic conductive sheets 31. The side walls of the alignment plate 27 are fixedly connected to the support plate 6 and the extension plate 15. The two ends of the alignment plate 27 away from the extension plate 15 are fixedly connected to the two circular frames 28 respectively. The four elastic conductive sheets 31 are evenly divided into two groups. The two groups of elastic conductive sheets 31 are fixedly connected to the inside of the two circular frames 28 respectively. The bottom surfaces of both ends of the lower strip 30 are provided with sockets 32. The top surfaces of the two sockets 32 are fixedly connected to the upper ends of the two plug blocks 29 respectively. The two plug blocks 29 are matched and aligned with the two groups of elastic conductive sheets 31 respectively. The outer walls of the two circular frames 28 are slidingly connected to the inner walls of the two sockets 32 respectively.

[0043] More specifically, by setting up a switch assembly, power can be supplied through four elastic conductive sheets 31 electrically connected to the power supply and control main board on the lawn mower body 1. After the lower bar 30 drops onto the support plate 6, the switch assembly is closed, and then the monitoring mechanism located inside the corresponding collection assembly is automatically started to monitor the amount of grass clippings inside the collection assembly in real time through the monitoring mechanism, so as to remind the operator to replace the collection assembly at an appropriate time.

[0044] As a preferred solution of the present invention, the four limit assemblies each include a limit box 12, a U-shaped block 20 and an elastic assembly. The side walls of the four U-shaped blocks 20 are respectively fixedly connected to the two ends of the upper strip 18 and the lower strip 30. The other sides of the four U-shaped blocks 20 are respectively fixedly connected to one end of the four limit boxes 12. The interiors of the four limit boxes 12 are each provided with a spring cavity 34. The four elastic assemblies are respectively located in the four spring cavities 34, and the four elastic assemblies are respectively connected to the two sliding rods 17. The openings of the four U-shaped blocks 20 are all facing the vertical plate 5, and the ends of the four U-shaped blocks 20 away from the vertical plate 5 are all connected to the collecting assembly.

[0045] More specifically, by setting a limit assembly, firstly, it can ensure that the collecting assembly is connected to the supporting assembly and the lawn mower body 1 more conveniently and quickly; secondly, it can also prevent the collecting assembly from being blown off the supporting assembly and the lawn mower body 1 by the impact force of the grass clippings during the collection of grass clippings.

[0046] As a preferred solution of the present invention, the elastic component includes an anti-slip rod 25, an insertion rod 26, two pull rods 19 and two push springs 33. The side wall of the U-shaped block 20 is penetrated by two anti-slip openings 35, and the surfaces of the two sliding rods 17 are penetrated by two insertion holes 22. One end of the anti-slip rod 25 and the insertion rod 26 are both located outside the spring cavity 34, and the ends of the anti-slip rod 25 and the insertion rod 26 outside the spring cavity 34 are slidingly connected to the two anti-slip openings 35 respectively, and the end of the insertion rod 26 outside the spring cavity 34 is also slidingly connected to the insertion hole 22. The end of the anti-slip rod 25 and the insertion rod 26 inside the spring cavity 34 is slidingly connected to the spring cavity 34, and the end of the anti-slip rod 25 and the insertion rod 26 inside the spring cavity 34 is also fixedly connected to the two pull rods 19 and the two push springs 33 respectively. The other ends of the two pull rods 19 pass through the outside of the limit box 12, and the other ends of the two push springs 33 are fixedly connected to the inner wall of the spring cavity 34.

[0047] More specifically, by setting up an elastic component, when it is necessary to connect the collecting component to the sliding rod 17 of the supporting component, the anti-slip rod 25 and the insertion rod 26 can be pulled apart. After aligning the collecting component with the sliding rod 17, it is only necessary to loosen the elastic component, and the elastic component can automatically limit the collecting component to the supporting component to prevent the collecting component from loosening and falling off.

[0048] It should be noted here that the two sockets 22 on the slide bar 17 are of different sizes, and the socket 22 at the lower end has a larger diameter. Similarly, the diameter of the plug rod 26 connected to the upper bar 18 is also smaller than the diameter of the plug rod 26 connected to the lower bar 30. The purpose of this design is that when the lower bar 30 slides down the slide bar 17, the plug rod 26 on the lower bar 30 will not be inserted into the socket 22 at the upper end.

[0049] As a preferred solution of the present invention, the collecting component includes a bottom plate 7, an upper plate 9, a breathable cloth 11 and two accordion plates 8. The same side of the bottom plate 7 and the upper plate 9 is fixedly connected to the side of the lower strip 30 and the upper strip 18 away from the vertical plate 5, and the bottom plate 7 and the upper plate 9 are fixedly connected to the breathable cloth 11 and the two accordion plates 8, wherein the breathable cloth 11 is located at one end of the bottom plate 7 and the upper plate 9 away from the vertical plate 5, and the two accordion plates 8 are located on both sides of the bottom plate 7 and the upper plate 9, respectively. The bottom surface of the bottom plate 7 is against the upper surface of the support plate 6, and the bottom surface of the upper plate 9 close to the end of the vertical plate 5 is against the upper surface of the anti-fall plate 21. Several monitoring mechanisms are located between the bottom plate 7 and the upper plate 9, and several monitoring mechanisms are connected to the upper plate 9.

[0050] More specifically, by providing a collection assembly, the grass clippings cut by the blade of the lawn mower body 1 and blown out from the grass discharge pipe 13 can be collected to prevent the grass clippings from flying directly to the outside;

[0051] It should be noted that the accordion board 8 is a mature technology and can be extended and retracted according to the usage. Figure 1 and Figure 2 As shown, the accordion board 8 during normal use is in an unfolded state (relatively high), and the spare accordion board 8 is in a folded state (relatively narrow).

[0052] As a preferred solution of the present invention, the monitoring mechanism includes an infrared sensor 24 and two hanging plates 23, the upper ends of the two hanging plates 23 are respectively fixedly connected to the bottom surfaces of the two ends of the upper plate 9, and the infrared sensor 24 is divided into a transmitting end and a receiving end, and the transmitting end and the receiving end of the infrared sensor 24 are respectively fixedly connected to the adjacent side of the two hanging plates 23.

[0053] More specifically, by setting up a monitoring mechanism inside the collection component, the amount of grass clippings inside the collection component can be monitored in real time to remind the operator to replace the new collection component in time; in addition, because there are multiple groups of monitoring mechanisms, the amount of grass inside the collection component can be reminded in segments through multiple groups of monitoring mechanisms, so that the operator can judge the amount of grass inside the collection component more intuitively and conveniently.

[0054] As a preferred solution of the present invention, the lawn mower body 1 is fixedly connected to one end of the grass outlet pipe 13 with two columns 2, and the upper ends of the two columns 2 are also fixedly connected with a mouth-shaped push handle 3. The mouth-shaped push handle 3 is located above the support plate 6, and the total length of the mouth-shaped push handle 3 is not less than the total length of the support plate 6.

[0055] More specifically, by providing the upright column 2 and the mouth-shaped push handle 3, the lawn mower body 1 can be pushed to move more conveniently.

[0056] As a preferred solution of the present invention, an end of the mouth-shaped push handle 3 close to the column 2 is fixedly connected to an audible and visual alarm 4.

[0057] More specifically, by setting up an audible and visual alarm 4 and connecting the audible and visual alarm 4 to the infrared sensor 24 and the power supply and control panel of the lawn mower body 1, when multiple sets of monitoring mechanisms detect an appropriate amount of grass clippings, different lights (such as green, orange and red) can be displayed or sounds can be emitted through the audible and visual alarm 4.

[0058] As a preferred solution of the present invention, two connecting rods 14 are fixedly connected to one side of the upper end of the vertical plate 5 away from the support block 16 , and the other ends of the two connecting rods 14 are fixedly connected to the two columns 2 respectively.

[0059] More specifically, by providing the connecting rod 14 , the connectivity between the vertical plate 5 and the column 2 can be increased, thereby increasing the overall stability of the vertical plate 5 .

[0060] like Figures 1 to 11As shown, the lawn mowing device for landscaping maintenance in the present invention can be used in the following steps:

[0061] First, the operator pushes the mouth-shaped push handle 3 to cooperate with the four wheels of the lawn mower body 1 to push the lawn mower body 1 to the lawn where weeding is required, then turns on the main power of the lawn mower body 1, and then changes the height of the blade according to the height of the lawn through the control panel of the lawn mower body 1, and then starts the blade through the control panel to weed the lawn;

[0062] While the blade is starting, the operator only needs to continue pushing the mouth-shaped push handle 3 to push the lawn mower body 1 and the support plate 6 and other components to move together. After the blade of the lawn mower body 1 cuts the grass, the grass clippings will be discharged from the grass discharge pipe 13 and sprayed between the upper plate 9, the bottom plate 7, the breathable cloth 11 and the two accordion plates 8 for collection;

[0063] The wind or some smaller debris that follows the grass clippings into the upper plate 9, the bottom plate 7, the breathable cloth 11 and the two accordion plates 8 will pass through the breathable cloth 11 to the outside, and the grass clippings that enter the upper plate 9, the bottom plate 7, the breathable cloth 11 and the two accordion plates 8 will be monitored in real time by the transmitting end and the receiving end of the infrared sensor 24 installed on the upper plate 9. When the first group of infrared sensors 24 detects that the amount of grass has been completely blocked for a certain period of time (for example, 15 seconds, the purpose of such a setting is to avoid false alarms caused by only a small amount of grass clippings blocking the infrared sensors 24 for a short time), the infrared sensors 24 will transmit the blocked electrical signal to the processor of the lawn mower body 1, and then the control panel of the lawn mower body 1 will generate light or broadcast voice through the sound and light alarm 4;

[0064] As more and more grass clippings enter the upper plate 9, the bottom plate 7, the breathable cloth 11 and the two accordion plates 8, the grass clippings will gradually block the second and third groups of infrared sensors 24. When the last group of infrared sensors 24 is continuously blocked, the operator can stop pushing the mouth-shaped push handle 3 by receiving a prompt from the sound and light alarm 4.

[0065] When the mouth-shaped push handle 3 stops being pushed, the entire lawn mower body 1 will stop in place. At the same time, because the lawn mower body 1 does not continue, it will not cut grass and grass clippings will not continue to be blown out of the grass discharge pipe 13. Therefore, at this time, the operator only needs to squat down and use both hands to pull the two pull rods 19 of the two limit boxes 12 at both ends of the upper bar 18 respectively;

[0066] When the two pull rods 19 are pulled, they will bring the anti-drop rod 25 and the insertion rod 26 into the spring cavity 34 of the limit box 12. At the same time, the anti-drop rod 25 and the insertion rod 26 will simultaneously compress the two push springs 33. When the anti-drop rod 25 and the insertion rod 26 are pulled out of the insertion hole 22 and the two anti-drop holes 35 respectively, the winding strip 18 can be separated from the slide rod 17, and then the winding strip 18 can be removed from the two slide rods 17. At this time, the anti-drop rod 25 and the insertion rod 26 are released.

[0067] The operator then pulls the two anti-slip rods 25 and the insert rod 26 at the ends of the lower bar 30 with both hands in the same manner as described above, and then the lower bar 30 is separated from the two slide bars 17. The operator then slightly lifts the lower bar 30 and the bottom plate 7 connected to it upward for a distance (because some grass clippings are collected between the upper plate 9 and the bottom plate 7, so they will not loosen). The two insert blocks 29 at the ends of the lower bar 30 can be pulled out from the two sets of elastic conductive sheets 31 of the two circular frames 28.

[0068] As the plug 29 separates from the elastic conductive sheet 31, the infrared sensors 24 connected to the upper plate 9 are powered off and the signal transmission with the lawn mower body 1 is also disconnected. The upper plate 9, the bottom plate 7, the breathable cloth 11, the two accordion plates 8 and the grass clippings inside can then be placed on the mowed lawn (for example, the back of the lawn is definitely the mowed part).

[0069] Then the grass clippings inside the upper plate 9, bottom plate 7, breathable cloth 11 and two accordion plates 8 of the previous group are removed from the support plate 6. At this time, the bottom plate 7 of the second group, which was originally placed on the first group of upper plates 9, lacks support. Therefore, the second group of bottom plates 7 and upper plates 9 will fall along the two slide bars 17 due to gravity. Because the insertion rod 26 on the bottom plate 7 is larger than the insertion hole 22 at the upper end of the slide bar 17, the bottom plate 7 will not be blocked by the insertion hole 22 (even if it gets stuck due to friction, the operator can manually pull the bottom plate 7). Then the bottom plate 7 continues to fall until it is blocked by the support plate 6 and stops. At the same time, the insertion rod 26 on the bottom plate 7 is just inserted into the insertion hole 22 at the lower end of the slide bar 17.

[0070] After the upper plate 9 has fallen a short distance, it will be blocked by the anti-fall plate 21 on the vertical plate 5, and the insertion rod 26 of the upper plate 9 will be inserted into the slide bar 17, thereby cooperating with the support of the anti-fall plate 21, so that the upper plate 9 can remain in a horizontal state, thereby forming a rectangular frame with the bottom plate 7, the breathable cloth 11 and the two accordion plates 8, so as to facilitate the continued collection of grass clippings. At this point, it only takes thirty seconds or even less to complete the replacement, which is convenient and quick.

[0071] Finally, it should be noted that the anti-slip rod 25 is provided to ensure that when the upper strip 18 and the lower strip 30 slide on the slide rod 17, the upper strip 18 and the lower strip 30 can only slide up and down without rotating or tilting.

[0072] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
