The front end of the lower surface of the first bracket 4 is equipped with symmetrically arranged support wheels 5, which provide support and guidance for the front end when the device moves. The rear end of the lower surface of the first bracket 4 is equipped with symmetrically arranged drive wheels 6. The drive wheels 6 are connected to a transmission box, which drives the drive wheels 6 to rotate. When the drive wheels 6 are started, the whole device will move along a preset path or a manually pushed path to perform the lawn mowing process during the movement.

[0036] See Figure 3 as well as Figures 6-7 To achieve the trimming purpose, a second support 9 is mounted on the first support 4. The second support 9 is generally U-shaped, and its bottom ends are fixedly connected to the adjacent first support 4. A drive shaft 15 is connected to the bottom bearing of the second support 9. A trimming part 8 is fixedly connected to the surface of the drive shaft 15. The trimming part 8 consists of multiple sets of spiral blades, and multiple sets of wedge-shaped support blocks are evenly arranged on the array plane of the spiral blades. The middle of the wedge-shaped support block is connected to the drive shaft 15, and its edge is fixed to the spiral blades in the same plane. During the rotation trimming process of the spiral blades, the wedge-shaped support blocks are... It provides stable support; a driven gear 17 is fixedly connected to one end of the drive shaft 15 outside the trimming section 8.

The trimming section 8 trims the lawn by rotating. The trimming efficiency of the trimming section 8 can be changed by adjusting the output power of the first drive motor.

[0037] A collection box 10 is provided on the rear side of the trimming section 8 to collect the trimmed weed debris. The collection box 10 has an opening facing the trimming section 8 and is shaped like a cone. The collection box 10 is fixedly mounted on the first support 4 by a rod. A base plate 11 is installed at the bottom of the collection box 10 to support the weed debris. (See reference...) Figure 4A second detection unit 12 is installed between the base plate 11 and the collection box 10. The second detection unit 12 is a pressure sensor used to detect the pressure of the weed debris carried on the base plate 11, thereby determining the amount of weed mixture. The second detection unit 12 is connected to the data processor. The amount of weed mixture determines whether to discharge the weed debris during the mowing process, so as to ensure the continuous and effective operation of the lawn mowing process. When too much weed debris accumulates inside the collection box 10, it will affect the mowing efficiency of the mowing unit 8. Therefore, the above intelligent monitoring method is set up to ensure efficient mowing.

[0038] A processing box 14 is installed above the collection box 10 for compressing and discharging weed debris. The processing box 14 has a hollow interior. An inlet is provided at the connection between the processing box 14 and the collection box 10. A set of flip-type first baffles 13 is installed at the inlet. For details, please refer to... Figure 5 A first rotating shaft is fixedly connected to the side of the first baffle 13 away from the feed inlet. The front and rear ends of the first rotating shaft are respectively connected to the first support lugs by bearings. The end of the first rotating shaft protruding from the first support lug is connected to a second drive motor. The second drive motor is connected to the second detection unit 12 via a data processor. When a set of first baffles 13 is closed, the processing process in the processing box 14 is not performed. When a set of first baffles 13 is fully or individually opened, the processing process in the processing box 14 is performed.

[0039] During the processing steps in the processing box 14, the weeds and debris are first sucked up and squeezed, and then the debris pile is discharged after being squeezed into blocks.

[0040] See Figure 6 - Figure 8 The top of the processing box 14 is fixedly equipped with a first telescopic part 20, and the front and rear parts of the processing box 14 are respectively fixedly equipped with a third telescopic part 22 and a second telescopic part 21. Sliding slots are provided at corresponding positions on the left and right sides of the processing box 14. A first push plate 24 is slidably connected to the left side of the processing box 14 at the position corresponding to the sliding slot. (See reference) Figure 9 A second baffle 18 is rotatably connected to the right side of the processing box 14 at the position corresponding to the sliding groove. A second rotating shaft is fixedly connected through the top of the second baffle 18. The front and rear ends of the second rotating shaft are respectively connected to the second support ear. A third drive motor is connected to the end of the second rotating shaft that protrudes from the second support ear. The third drive motor is connected to the data processor signal.

[0041] A discharge rail 19 is provided on the side of the second baffle 18 away from the processing box 14. The discharge rail 19 is U-shaped. One side of the discharge rail 19 is fixedly connected to the outer wall of the processing box 14 corresponding to the adjacent sliding groove, and the other side of the discharge rail 19 is fixedly connected to the inner wall of the outer box 1. (Refer to...) Figure 2The processing box 14 is connected to the discharge rail 19 on one side and has a discharge port 7. The size of the discharge port 7 is not smaller than the size of the sliding groove, which facilitates the discharge of the weed pile.

[0042] Further, refer to Figure 10 , Figure 11 A rack 26 is fixedly connected to the side of the first push plate 24 away from the processing box 14. A second drive gear 27 is meshed with the side of the rack 26 near the processing box 14. A third rotating shaft is connected through the middle of the second drive gear 27. A third support lug is connected to one end of the third rotating shaft by a bearing. A fourth drive motor is connected to the other end of the third rotating shaft. A fourth bracket 25 is fixedly connected to the bottom of both the fourth drive motor and the third support lug. A third bracket 23 is fixedly connected to the other end of the fourth bracket 25 and is fixedly connected to the first bracket 4 for support. A limit block 29 is slidably connected to the top of the rack 26. The non-sliding contact side of the limit block 29 is fixedly connected to the inner wall of the outer box 1. When the fourth drive motor is started, the second drive gear 27 drives the rack 26 and the first push plate 24 to move into the processing box 14, which can compress the weed fragments and discharge the weed pile.

[0043] Further, refer to Figure 8 The output ends of the first telescopic part 20, the second telescopic part 21, the third telescopic part 22, and the first push plate 24 are all fixedly connected to a squeezing mechanism on one side inside the processing box 14. The squeezing mechanism includes a hollow second push plate 31. A partition plate 32 is fixedly connected to the side of the second push plate 31 facing the middle of the processing box 14 by bolts. Several air holes 28 are opened on the surface of the partition plate 32. In addition, the surface of the second push plate 31 is connected to an air pipe 30 through a branch pipe. The branch pipe can be a telescopic pipe or have sufficient length to ensure that the branch pipe can move with the second push plate 31. The other end of the air pipe 30 is connected to a suction pump. A humidity sensor is installed on the side of the air pipe 30 near the suction pump. The humidity sensor and the suction pump are both connected to the data processor.

[0044] The rear end support of the first bracket 4 is connected to a power supply unit, which is used to effectively supply power to the above-mentioned electrical components and ensure the effective operation of each component.

[0045] In this embodiment, the first step is to select operating parameters through the control screen 2. The operating parameters include travel speed v, trimming speed r, and weighing threshold g. The travel speed is used to control the travel speed of the overall device and is related to the output power when the transmission box drives the drive wheel 6 to rotate. The trimming speed is used to control the speed of the trimming unit 8 when trimming the lawn. The weighing threshold g is used to control the time point when the second detection unit 12 transmits the collection and compression signal to the data processor. That is, when the second detection unit 12 measures the set weighing threshold, the processing box 14 will collect and compress the weed debris.

[0046] Furthermore, the user can determine the operating parameters according to the area of ​​the site. If the site is too large and / or the user does not select the operating parameters, the user can directly select the default adjustment mode displayed on the control screen 2. The default adjustment mode first performs the trimming process with the preset travel speed v0, trimming speed r0, and weighing limit value g0, and then adjusts the trimming process according to the data measured by the first detection unit 3 and the second detection unit 12.

[0047] In the second step, the drive wheel 6 drives the entire device to move according to the preset travel speed v0, the trimming unit 8 performs the trimming and collection process according to the preset trimming speed r0, and the second detection unit 12 performs the trimming and collection process according to the weighing limit value g0.

[0048] Third, the first detection unit 3 performs visual detection of the environment in the designated detection area ahead at regular intervals during the movement to obtain lawn data, including the actual weed density and the actual median height of the weeds.

[0049] The actual weed density is recorded as Cs and the actual median height of the weeds is recorded as Hs. When the preset travel speed v0 is determined and the pruning unit 8 is operated at the pruning speed r0, the corresponding ideal weed density is recorded as C0 and the ideal median height of the weeds is recorded as H0, so as to ensure the best pruning effect.

[0050] Specifically, the first detection unit 3 records the area of ​​the designated detection area as S. The first detection unit 3 and the data processor identify weeds and define a two-dimensional XY coordinate system for the designated detection area, with the starting detection point at the lower left corner of the designated detection area as the origin. X represents the lateral distance or lateral coordinate of the designated detection area, and Y represents the longitudinal distance or longitudinal coordinate of the designated detection area. After identifying the weeds, the corresponding longitudinal height is marked in the coordinate system according to the height of the weeds. After the marking is completed, the height position points are connected to form a curve. The area s of the weeds in the designated detection area is calculated using the principle of calculus. The actual weed density Cs = s / S. Several height points are selected on the curve to form a height dataset {Hi}, where i represents the marker number of the height point, which is an integer from 1 to n, and n is the number of height points selected. After sorting the height dataset from smallest to largest, the actual median height value Hm of the weeds is determined.

[0051] Fourth, after acquiring the lawn data for the next time period, the data processor will adjust the actual travel speed v for that next time period. s and the actual pruning speed r s ;

[0052] First, the actual travel speed v sRelated to the first comparison coefficient §1, which is the ratio of actual weed density Cs to ideal weed density C0, the actual travel rate level is determined based on the range of Cs / C0; for example, when 0 < §1 ≤ 1, the actual travel rate v s A preset travel speed v0 is adopted, where the preset travel speed is the first speed level; when §1>1, the actual travel speed v s The preset adjustment travel speed α·v0 is adopted, requiring 0.5≤α<1, which is recorded as the second-level speed level. This embodiment only lists two levels of judgment settings, and the judgment levels can be further subdivided or expanded according to the actual use and corresponding adjustment measures can be implemented. Through the above settings, the mowing device can adjust the travel speed during the mowing process according to the weed density in the lawn data under a fixed time period. Through intelligent adjustment of the travel speed, it can mow lawns with uneven weed distribution for a sufficient amount of time to ensure the mowing effect of the lawn.

[0053] Then, the mowing speed under fixed time periods will be intelligently adjusted by combining the weed density and median height of the weeds in the lawn data to improve the quality and efficiency of mowing. Specifically, a second comparison coefficient §2 is established, which is the ratio of the actual median height of the weeds Hm to the ideal median height of the weeds H0. The data processor will determine the level of the actual mowing speed based on the first comparison coefficient §1 and the second comparison coefficient §2. A product coefficient value §1·§2 is established between the two. The larger the product coefficient value, the higher the difficulty of weed treatment in the detection area. If the treatment difficulty is higher, the actual mowing speed needs to be adjusted accordingly.

[0054] For example, when 0 < §1·§2 ≤ 1, the actual pruning speed r s The preset pruning speed r0 is still used, where the preset pruning speed is the first speed level; when §1·§2>1, the actual pruning speed r s The preset adjustment speed β·r0 is adopted, requiring β>1, and it is recorded as the second-level speed level. Similarly, the judgment level can be further subdivided or expanded according to the actual use and corresponding adjustment measures can be implemented. According to the above settings, the mowing device can comprehensively adjust the mowing speed during the mowing process based on the weed density and median height value of the lawn data under a fixed time period. Through intelligent adjustment of the mowing speed, it can effectively mow lawns with specific weed quantity and uneven growth length, ensuring lawn mowing effect while matching the corresponding power output to achieve efficient energy use.

[0055] It should be noted that the first detection unit 3 also has the function of recognizing hard obstacles in front. The data processor will determine whether the device should perform a warning pause procedure based on the size of the obstacle to ensure the safety of the pruning device during operation.

[0056] In the fifth step, most of the trimmed weeds are guided into the collection box 10 by the rotation and travel direction of the trimming part 8. The second detection part 12 detects the actual pressure value Gs of the weed fragments in real time. Based on the comparison result between the actual pressure value and the weighing limit value, the collection and compression process of the processing box 14 is performed to form a weed pile.

[0057] Specifically, when the second detection unit 12 measures that Gs≥g0, the data processor controls the first baffle 13 to open, the suction pump starts at high power, the processing box 14 is under negative pressure and the weeds in the collection box 10 are sucked into the processing box 14.

[0058] After the suction set time T1, the first baffle 13 gradually rotates to the closed state, the suction pump is adjusted to low power and starts, the extrusion mechanism moves towards the weed debris inside the processing box 14 and extrudes it, the suction pump at low power performs internal air extraction on the gradually forming weed pile, and the compactness between the weed piles is improved under the action of extrusion and air extraction. Under the action of continuous processing time T2, the suction pump, the second telescopic part 21 and the third telescopic part 22 stop working, and the extrusion and forming of the weed pile is completed.

[0059] In addition, a humidity sensor is used to detect the airflow humidity in the weed pile under the suction action, denoted as Hu. The airflow humidity is affected by environmental humidity factors and the amount of sap in the weeds after cutting and trimming. When the measured airflow humidity is too high, the suction pump is adjusted to medium power and more water vapor is discharged under a certain time to avoid the problem of insufficient compactness due to excessive moisture between weed piles, thereby assisting in the effective formation of the weed pile.

[0060] The pump's output is positioned towards the lawn, and the extracted airflow is sprayed onto the lawn, while excess sap is returned to the lawn.

[0061] The sixth step is to remove the formed weed piles to facilitate internal emptying for continued trimming. This also makes it easier to manually collect and process the weed piles, reducing manpower and improving processing efficiency.

[0062] The discharge process involves the above-mentioned suction pump, second telescopic part 21, and third telescopic part 22 ceasing to function, the second baffle 18 rotating and opening to more than 90 degrees, the fourth drive motor starting, and the second drive gear 27 driving the rack 26 and the first push plate 24 to continuously move towards the discharge rail 19 and the discharge port 7 to discharge the weed pile. After discharge, each structure returns to its original state, facilitating the next collection and compression process.
