Description

Technical Field

[0001] The present invention relates to the technical field of landscaping maintenance, and specifically to a lawn mowing device for landscaping maintenance. Background Art

[0002] Landscaping refers to the activity of planting vegetation and designing landscapes in cities, villages or specific areas through scientific and reasonable means to improve environmental quality, beautify living environments, protect natural ecology and enhance people's quality of life. In order to maintain and improve landscape quality, extend the lifespan of plants and achieve ecological benefits, landscaping maintenance is often required, and mowing is a very important part. Currently, lawn mowers are mostly used.

[0003] Currently, the patent with the publication number CN221178470U discloses a lawn mower, which includes a lawn mower main body, a push rod rotatably installed on the lawn mower main body, a locking device disposed between the fixed end of the lawn mower main body and the push rod and adapted to limit the relative angle between the push rod and the lawn mower 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 through a traction member and adapted to release the restricted state of the locking device. This lawn mower realizes the control of the locking device at the fixed end of the push rod armrest through the height adjustment handle fixed at the armrest end of the push rod. The entire height adjustment process does not require the user to rely on other auxiliary devices or bend down to adjust, which is more convenient.

[0004] However, in the actual use process of the above-mentioned lawn mower, the following problems still exist: Traditional lawn mowers generally adopt a single grass collection bag design, and its main function is to collect grass fragments in real time during operation to avoid secondary scattering of grass clippings. However, this structure has significant defects: the capacity of the grass collection bag is fixed, and it is necessary to stop the machine regularly for manual emptying. Specifically, when the grass clippings accumulate to the upper limit of the bag body, the operator must perform the following steps: first, release the grass collection bag fixing mechanism, then detach the full grass collection bag, then pour out the grass clippings, and finally reinstall a new bag or reuse the old bag after cleaning.

[0005] This process not only generates additional labor intensity (a single operation may take 3 - 5 minutes or even longer), but more importantly, if the machine is in a continuous operation state, energy is continuously wasted, and if it is temporarily stopped, the subsequent restart requires repeating the ignition procedure. When facing large - area lawn scenarios (such as commercial lawns or municipal projects), frequent loading and unloading operations will cause the lawn mower to fall into the "start - stop cycle" dilemma: the engine needs to be pre - heated during the start - up phase (a gasoline engine needs a certain time to idle, and a diesel engine may produce higher emissions), and after shutdown and restart, there is a problem of cold engine ignition delay, which is very inconvenient. Summary of the Invention

[0006] 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.

[0007] To achieve the above object, the present invention provides the following technical solution: A lawn mowing device for landscaping maintenance, including a mower main body and a grass outlet pipe installed behind the mower main body. One end of the mower main body close to the grass outlet pipe is fixedly connected with an extension plate and a U-shaped frame. The U-shaped frame is aligned with the grass outlet pipe, and the bottom surface of the U-shaped frame is fixedly connected with the upper surface of the extension plate. The end of the extension plate and the U-shaped frame away from the mower main body is connected with a support assembly. The upper end of the support assembly is connected with four limiting assemblies. The four limiting assemblies are divided into two groups. The two groups of limiting assemblies are respectively connected with an upper strip and a lower strip. One side of the upper strip and the lower strip is connected with a collection component. The inside of the collection component is connected with several monitoring mechanisms. The collection component and several monitoring mechanisms are both located above the support assembly. A switch assembly for controlling the opening and closing of several monitoring mechanisms is connected between the lower strip and the extension plate. The upper strip, the lower strip, the collection component, the monitoring mechanism and the four limiting assemblies form a module, and the total number of modules is several.

[0008] Further, the support assembly includes a vertical plate, a support plate, a falling prevention plate, two support blocks and two sliding rods.

Sockets are respectively opened on the bottom surfaces of both ends of the lower strip, and the upper ends of the two insertion blocks are respectively fixedly connected with the top surfaces of the two sockets. The two insertion blocks are respectively matched and aligned with the two groups of elastic conductive sheets. The outer walls of the two U-shaped frames are respectively slidably connected with the inner walls of the two sockets.

[0010] Further, the four limiting components each include a limiting box, a U-shaped block, and an elastic component. The side walls of the four U-shaped blocks are respectively fixedly connected to the two ends of the upper strip and the lower strip. The other sides of the four U-shaped blocks are respectively fixedly connected to one ends of the four limiting boxes. Spring cavities are respectively formed inside the four limiting boxes. The four elastic components are respectively located in the four spring cavities, and the four elastic components are respectively connected to two sliding rods. The openings of the four U-shaped blocks all face the vertical plate, and one ends of the four U-shaped blocks away from the vertical plate are all connected to the collection component.

[0011] Further, the elastic component includes an anti-detachment rod, an insertion rod, two pull rods, and two pushing springs. Two anti-detachment openings are formed through the side wall of the U-shaped block. Two insertion holes are respectively formed through the surfaces of the two sliding rods. One ends of the anti-detachment rod and the insertion rod are both located outside the spring cavity, and the ends of the anti-detachment rod and the insertion rod located outside the spring cavity are respectively slidably connected to the two anti-detachment openings. The end of the insertion rod located outside the spring cavity is also slidably connected to the insertion hole. One ends of the anti-detachment rod and the insertion rod located inside the spring cavity are both slidably connected to the spring cavity, and one ends of the anti-detachment rod and the insertion rod located inside the spring cavity are also respectively fixedly connected to the two pull rods and the two pushing springs. The other ends of the two pull rods both penetrate to the outside of the limiting box, and the other ends of the two pushing springs are both fixedly connected to the inner wall of the spring cavity.

[0012] Further, the collection component includes a bottom plate, an upper plate, a breathable cloth, and two bellows plates. The same sides of the bottom plate and the upper plate are respectively fixedly connected to the sides of the lower strip and the upper strip away from the vertical plate. The breathable cloth and the two bellows plates are both fixedly connected between the bottom plate and the upper plate. The breathable cloth is located at one end of the bottom plate and the upper plate away from the vertical plate. The two bellows plates are respectively located on both sides of the bottom plate and the upper plate. The bottom surface of the bottom plate abuts against the upper surface of the support plate, and the bottom surface of one end of the upper plate close to the vertical plate abuts against the upper surface of the anti-falling plate.

[0014] Further, two columns are fixedly connected to one end of the lawn mower main body close to the grass outlet pipe. The upper ends of the two columns are fixedly connected with a mouth-shaped push handle at the same time. The mouth-shaped push handle is located above the support plate, and the total length of the mouth-shaped push handle is not less than the total length of the support plate.

[0015] Further, an audible and visual alarm is fixedly connected to one end of the mouth-shaped push handle close to the column.

[0016] Further, two connecting rods are fixedly connected to one side of the upper end of the vertical plate away from the support block. The other ends of the two connecting rods are respectively fixedly connected to the two columns.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. For this lawn mowing device used for landscaping maintenance, through the cooperation of the support component (vertical plate, sliding rod) and the limit component (U-shaped block, elastic component), modular installation of the collection component is achieved. The operator only needs to pull the pull rod to unlock the plug rod, and can complete the disassembly and replacement of the collection component within 30 seconds, avoiding the complex steps required for the disassembly of the traditional grass collection bag and significantly reducing the downtime; 2. For this lawn mowing device used for landscaping maintenance, multiple infrared sensors are installed inside the collection component, and the grass clipping accumulation amount is monitored through the occlusion situation between the transmitting end and the receiving end. When the grass clippings successively cover sensors at different heights, the sound and light alarm emits green, orange, and red warnings in segments (for example, the green light indicates normal, and the red light indicates full load), helping the operator accurately judge the replacement time and avoiding problems such as premature shutdown or grass clipping overflow; 3. For this lawn mowing device used for landscaping maintenance, the switch component (plug block, loop frame, elastic conductive sheet) automatically closes the circuit and starts the monitoring mechanism when the collection component is installed in place; the circuit automatically disconnects during disassembly, preventing the risk of accidental touch or short circuit. This design eliminates the need for manual operation of the power switch, improving safety and operation convenience; 4. For this lawn mowing device used for landscaping maintenance, the elastic component (anti-disconnection rod, plug rod, push spring) ensures that the collection component is firmly fixed on the sliding rod during operation, preventing loosening caused by vibration or grass clipping impact. At the same time, the double limit design of the anti-falling plate and the support plate keeps the collection component horizontally stable and avoids grass leakage due to tilting; 5. For this lawn mowing device used for landscaping maintenance, the collection component adopts a combination of breathable cloth and bellows board: the breathable cloth allows air flow to reduce the internal pressure and prevent grass clipping blockage; the bellows board can extend horizontally as the grass amount increases, temporarily expanding the collection space and delaying the full load time to adapt to the requirements of different operation scenarios; 6. For this lawn mowing device used for landscaping maintenance, after the first module is full, the second module can automatically slide down along the sliding rod to the working position, and the operator can switch to the standby module without stopping the machine, realizing continuous operation. This design is especially suitable for large-area lawns, reducing energy waste and cold machine restart problems caused by the "start-stop cycle". BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Please refer to Figures 1 - 11, a lawn mowing device for landscaping maintenance, including a mower main body 1 and a grass outlet pipe 13 installed behind the mower main body 1. One end of the mower main body 1 close to the grass outlet pipe 13 is fixedly connected with an extension plate 15 and a U-shaped frame 10. The U-shaped frame 10 is aligned with the grass outlet pipe 13. The bottom surface of the U-shaped frame 10 is fixedly connected with the upper surface of the extension plate 15. One end of the extension plate 15 and the U-shaped frame 10 away from the mower main body 1 is connected with a support assembly. The upper end of the support assembly is connected with four limiting assemblies. The four limiting assemblies are divided into two groups. The two groups of limiting assemblies are respectively connected with an upper strip 18 and a lower strip 30. One side of the upper strip 18 and the lower strip 30 is connected with a collection assembly. The inside of the collection assembly is connected with several monitoring mechanisms. The collection assembly and several monitoring mechanisms are both located above the support assembly. A switch assembly for controlling 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 collection assembly, the monitoring mechanisms and the four limiting assemblies form a module, and the total number of modules is several.

[0022] More specifically, the above-mentioned mower main body 1 and grass outlet pipe 13 are both existing mature technologies. Moreover, the mower main body 1 also includes structural components such as a power component (engine), a cutting component (cutter head and blade), 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 ), and no detailed description will be made here.

[0023] As a preferred solution of the present invention, the support assembly includes a vertical plate 5, a support plate 6, a falling prevention 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 with one end of the U-shaped frame 10 away from the mower main body 1. Both sides of the upper end of the vertical plate 5 are respectively fixedly connected with 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 with the upper ends of the two sliding rods 17. The lower ends of the two sliding rods 17 are respectively fixedly connected with both sides of the upper surface of the support plate 6. One end of the support plate 6 close to the sliding rod 17 is fixedly connected with one end of the extension plate 15 away from the mower main body 1. One side of the falling prevention plate 21 is fixedly connected with the side of the vertical plate 5 away from the U-shaped frame 10. The falling prevention plate 21 and the support plate 6 are respectively abutted against the upper strip 18 and the lower strip 30, and the support plate 6 is also connected with the switch assembly.

[0024] More specifically, by setting the support assembly, support can be provided for the switch assembly and several collection assemblies, avoiding contact with the ground due to weight and thus increasing the wear situation.

[0025] As a preferred embodiment of the present invention, the switch assembly includes an alignment plate 27, two U-shaped frames 28, two insertion blocks 29, and four elastic conductive sheets 31. The side wall of the alignment plate 27 is fixedly connected to both the support plate 6 and the extension plate 15. The two ends of the alignment plate 27 on the side away from the extension plate 15 are respectively fixedly connected to the two U-shaped frames 28. The four elastic conductive sheets 31 are evenly divided into two groups, and the two groups of elastic conductive sheets 31 are respectively fixedly connected inside the two U-shaped frames 28. Sockets 32 are provided at the bottom surfaces of both ends of the lower strip 30. The top surfaces of the two sockets 32 are respectively fixedly connected to the upper ends of the two insertion blocks 29. The two insertion blocks 29 are respectively aligned with the two groups of elastic conductive sheets 31. The outer walls of the two U-shaped frames 28 are respectively slidably connected to the inner walls of the two sockets 32.

[0026] More specifically, by providing the switch assembly, power can be supplied through the four elastic conductive sheets 31 electrically connected to the power supply and the control main board on the lawn mower body 1. After the lower strip 30 descends onto the support plate 6, the switch assembly closes, 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, so as to remind the operator to replace the collection assembly at an appropriate time.

[0027] As a preferred embodiment of the present invention, the four limiting components each include a limiting box 12, a U-shaped block 20, and an elastic component. The side walls of the four U-shaped blocks 20 are respectively fixedly connected to both 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 ends of the four limiting boxes 12. Spring cavities 34 are provided inside the four limiting boxes 12. The four elastic components are respectively located inside the four spring cavities 34, and the four elastic components are respectively connected to the two sliding rods 17. The openings of the four U-shaped blocks 20 all face the vertical plate 5. One ends of the four U-shaped blocks 20 away from the vertical plate 5 are all connected to the collection assembly.

[0028] More specifically, by providing the limiting components, firstly, it can ensure that the collection assembly is more conveniently and quickly connected to the support assembly and the lawn mower body 1; secondly, it can also prevent the collection assembly from being blown off the support assembly and the lawn mower body 1 by the impact force of the grass clippings during the collection of grass clippings.

[0029] As a preferred embodiment of the present invention, the elastic component includes a anti - detachment rod 25, an insertion rod 26, two pull rods 19 and two pushing springs 33. Two anti - detachment openings 35 are formed through the side wall of the U - shaped block 20. Two insertion holes 22 are formed through the surfaces of the two sliding rods 17. One ends of the anti - detachment rod 25 and the insertion rod 26 are both located outside the spring cavity 34, and the ends of the anti - detachment rod 25 and the insertion rod 26 located outside the spring cavity 34 are respectively slidably connected to the two anti - detachment openings 35. The end of the insertion rod 26 located outside the spring cavity 34 is also slidably connected to the insertion hole 22. One ends of the anti - detachment rod 25 and the insertion rod 26 located inside the spring cavity 34 are both slidably connected to the spring cavity 34, and the ends of the anti - detachment rod 25 and the insertion rod 26 located inside the spring cavity 34 are respectively fixedly connected to the two pull rods 19 and the two pushing springs 33. The other ends of the two pull rods 19 both penetrate to the outside of the limit box 12, and the other ends of the two pushing springs 33 are both fixedly connected to the inner wall of the spring cavity 34.

[0030] More specifically, by providing the elastic component, when it is necessary to connect the collection component to the sliding rod 17 of the support component, the anti - detachment rod 25 and the insertion rod 26 can be pulled apart. After aligning the collection component with the sliding rod 17, simply releasing the elastic component can automatically limit the collection component on the support component to prevent the collection component from loosening and falling off.

[0031] It should be particularly noted here that: the two insertion holes 22 on the sliding rod 17 have different sizes. The diameter of the lower insertion hole 22 is larger. Similarly, the diameter of the insertion rod 26 connected to the upper strip 18 is smaller than the diameter of the insertion rod 26 connected to the lower strip 30. The purpose of this design is that when the lower strip 30 slides down along the sliding rod 17, the insertion rod 26 on the lower strip 30 will not be inserted into the upper insertion hole 22.

[0032] As a preferred embodiment of the present invention, the collection component includes a bottom plate 7, an upper plate 9, a breathable cloth 11 and two bellows plates 8. The same sides of the bottom plate 7 and the upper plate 9 are respectively fixedly connected to the sides of the lower strip 30 and the upper strip 18 away from the vertical plate 5. The breathable cloth 11 and the two bellows plates 8 are both fixedly connected between the bottom plate 7 and the upper plate 9. 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. The two bellows plates 8 are respectively located on both sides of the bottom plate 7 and the upper plate 9. The bottom surface of the bottom plate 7 abuts against the upper surface of the support plate 6, and the bottom surface of the end of the upper plate 9 close to the vertical plate 5 abuts against the upper surface of the anti - falling plate 21. A number of monitoring mechanisms are all located between the bottom plate 7 and the upper plate 9, and a number of monitoring mechanisms are all connected to the upper plate 9.

[0033] More specifically, by providing the collection component, the grass clippings cut by the blade of the lawn mower main body 1 and blown out from the grass outlet pipe 13 can be collected to prevent the grass clippings from directly flying to the outside. It should be specifically noted here that the bellows board 8 is a mature existing technology and can adaptively expand and contract according to the usage situation. Its two states are as shown in Figure 1 and Figure 2 . During normal use, the bellows board 8 is in the unfolded state (relatively high), and the spare bellows board 8 is in the folded state (relatively narrow).

[0034] As a preferred embodiment 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 at both ends of the upper plate 9. 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 one side adjacent to the two hanging plates 23.

[0035] More specifically, by arranging the 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 more intuitively and conveniently judge the amount of grass inside the collection component.

[0036] As a preferred embodiment of the present invention, two columns 2 are fixedly connected to one end of the lawn mower main body 1 close to the grass outlet pipe 13. The upper ends of the two columns 2 are simultaneously 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.

[0037] More specifically, by arranging the columns 2 and the mouth-shaped push handle 3, it is more convenient to push the lawn mower main body 1 to move.

[0038] As a preferred embodiment of the present invention, an audible and visual alarm 4 is fixedly connected to one end of the mouth-shaped push handle 3 close to the column 2.

[0039] More specifically, by arranging the audible and visual alarm 4 and connecting the audible and visual alarm 4 to the power supply and control board of the infrared sensor 24 and the lawn mower main body 1, when multiple groups 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.

[0040] As a preferred embodiment of the present invention, two connecting rods 14 are fixedly connected to one side of the upper end of the vertical plate 5 far from the support block 16. The other ends of the two connecting rods 14 are respectively fixedly connected to the two columns 2.

[0041] More specifically, by arranging the connecting rods 14, the connectivity between the vertical plate 5 and the columns 2 can be increased, and the overall stability of the vertical plate 5 can be increased.

[0042] Such as Figures 1 to 11As shown in the figure, when the lawn mowing equipment for landscaping maintenance in the present invention is in use, it can be carried out according to the following steps: First, the operator pushes the mouth-shaped push handle 3 and uses the four wheels of the lawn mower main body 1 to push the lawn mower main body 1 to the lawn position where weeding is required. Subsequently, turn on the total power supply of the lawn mower main body 1. Then, according to the height of the lawn, change the height of the blade through the control board of the lawn mower main body 1. Subsequently, start the blade through the control board, and then the lawn can be weeded. While the blade is starting, the operator only needs to continue to push the mouth-shaped push handle 3, then the lawn mower main body 1 and components such as the support plate 6 will move together. After the blade of the lawn mower main body 1 cuts the grass, the grass clippings will be transmitted from the grass outlet pipe 13 and just sprayed into the space between the upper plate 9, the bottom plate 7, the breathable cloth 11 and the two bellows plates 8 for collection. 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 bellows plates 8 will pass through the breathable cloth 11 to the outside. The grass clippings that enter the inside of the upper plate 9, the bottom plate 7, the breathable cloth 11 and the two bellows 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 monitors that the grass amount has completely blocked for a certain period of time (for example, 15 seconds. The purpose of this setting is to avoid false alarms caused by only a small amount of grass clippings blocking the infrared sensor 24 for a short time), at this time, the infrared sensor 24 will transmit the blocked electrical signal to the processor of the lawn mower main body 1, and then through the control board of the lawn mower main body 1, the sound and light alarm 4 will emit light or broadcast voice. After that, as more and more grass clippings enter the inside of the upper plate 9, the bottom plate 7, the breathable cloth 11 and the two bellows plates 8, the grass clippings will gradually block the second group and the third group 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 according to the prompt of the sound and light alarm 4. When the mouth-shaped push handle 3 stops being pushed, the entire lawn mower main body 1 will stop in place. At the same time, because the lawn mower main body 1 does not continue, it will not mow the grass and no more grass clippings will be blown out from the grass outlet pipe 13. Therefore, at this time, the operator only needs to squat down and then use both hands to pull the two pull rods 19 of the two limit boxes 12 at both ends of the upper strip 18 respectively. When the two pull rods 19 are pulled, they will drive the anti-disengagement rod 25 and the insertion rod 26 into the spring cavity 34 of the limit box 12 together. At the same time, the anti-disengagement rod 25 and the insertion rod 26 will compress the two push springs 33 at the same time. When the anti-disengagement rod 25 and the insertion rod 26 are respectively pulled out from the insertion hole 22 and the two anti-disengagement openings 35, at this time, the upper strip 18 can be separated from the sliding rod 17, and then the upper strip 18 can be removed from the two sliding rods 17. At this time, release the anti-disengagement rod 25 and the insertion rod 26. After that, the operator pulls the two anti - detachment rods 25 and the insertion rods 26 at both ends of the lower strip 30 with both hands in the above - mentioned manner. After that, the lower strip 30 can be separated from the two sliding rods 17 in the same way. Then, the lower strip 30 and the bottom plate 7 connected to the lower strip 30 are gently lifted upward by a certain distance (because there are several grass clippings collected between the upper plate 9 and the bottom plate 7, so it will not collapse). Then, the two insertion blocks 29 at both ends of the lower strip 30 can be pulled out from the two groups of elastic conductive sheets 31 of the two loop - shaped frames 28; As the insertion block 29 is separated from the elastic conductive sheet 31, at this time, several infrared sensors 24 connected to the upper plate 9 are powered off and the signal transmission with the lawn mower main body 1 is also disconnected. Then, the upper plate 9, the bottom plate 7, the breathable cloth 11, the two bellows plates 8 and the grass clippings inside can be placed on the already mowed lawn together (for example, the mowed part is surely behind oneself); Subsequently, the grass clippings inside the upper plate 9, the bottom plate 7, the breathable cloth 11 and the two bellows plates 8 of the previous group are taken away from the support plate 6. At this time, the bottom plate 7 of the second group that was originally placed on the first - group upper plate 9 lacks support. Therefore, the second - group bottom plate 7 and the upper plate 9 will descend along the two sliding rods 17 due to gravity. Since the size of the insertion rod 26 on the bottom plate 7 is larger than the insertion hole 22 at the upper end of the sliding rod 17, the bottom plate 7 will not be blocked by this insertion hole 22 (even if it gets stuck due to friction, the operator can manually pull the bottom plate 7). Subsequently, the bottom plate 7 descends until it is blocked by the support plate 6 and stops. At the same time, the insertion rod 26 on the bottom plate 7 just inserts into the insertion hole 22 at the lower end of the sliding rod 17; After the upper plate 9 descends a short distance, it will be blocked by the anti - falling plate 21 on the vertical plate 5. And at this time, the insertion rod 26 on the upper plate 9 will just insert into the sliding rod 17, so as to cooperate with the support of the anti - falling plate 21 to make the upper plate 9 maintain a horizontal state. Thus, in cooperation with the bottom plate 7, the breathable cloth 11 and the two bellows plates 8, it presents a rectangular frame to facilitate the continuous collection of grass clippings. It only takes 30 seconds or even less to complete the replacement, which is convenient and fast; Finally, it should be particularly noted that: by setting the anti - detachment rod 25, it is to ensure that when the upper strip 18 and the lower strip 30 slide on the sliding rod 17, the upper strip 18 and the lower strip 30 can only slide up and down, and will not rotate or tilt.
