[0021] Example 1: Please refer to Figures 1-8 The present invention provides a technical solution: an energy-saving lawnmower based on solar-assisted power supply, including a base plate 1 and casters 2, with a mowing structure provided on the top of the base plate 1; The mowing structure includes an adjustment mechanism 3, a mowing mechanism 4, and a spraying mechanism 5; Adjustment mechanism 3 includes a bearing plate 301, a movable rod 302, a first fixed plate 303, a fixing bolt 304, and a second fixed plate 305. The top of the bearing plate 301 is rotatably connected to the bottom of the movable rod 302. The outer wall of the movable rod 302 is connected to the inner wall of the first fixed plate 303. The inner wall of the first fixed plate 303 is threadedly connected to the outer wall of the fixing bolt 304. The top of the movable rod 302 is connected to the bottom of the second fixed plate 305. A first rotating rod 306 is rotatably connected to the inner side of the second fixed plate 305. A swing plate 307 is fixedly installed on the outer wall of the first rotating rod 306. A rotating plate 308 is fixedly installed at one end of the rotating rod 306. A sliding plate 309 is slidably connected to the outer wall of the rotating rod 306. A limit rod 310 is fixedly installed on one side of the sliding plate 309. A guide rod 311 is fixedly installed on one side of the swing plate 307. A placement plate 312 is fixedly installed on the top of the swing plate 307. A limit plate 313 is fixedly installed on the top of the placement plate 312. A threaded rod 314 is threadedly connected to the inner wall of the limit plate 313. A clamping plate 315 is rotatably connected to the bottom of the threaded rod 314. A solar panel 316 is pressed into contact with the bottom of the clamping plate 315. In this embodiment, a limiting hole is provided at the top of the support plate 301, and the bottom of the fixing bolt 304 is threaded to the inner wall of the limiting hole. There are two fixing bolts 304, which are symmetrically distributed on the inner wall of the first fixing plate 303. The second fixing plate 305 is U-shaped, so that the angle of the solar panel 316 can be adjusted quickly and conveniently, and thus can be used better. Furthermore, an adjustment hole is provided on one side of the fixed plate 305, one end of the limiting rod 310 is inserted into the inner wall of the adjustment hole, a spring is fixedly installed between one side of the sliding plate 309 and one side of the rotating plate 308, a sliding groove is provided on one side of the fixed plate 305, and one end of the guide rod 311 is slidably connected to the inner wall of the sliding groove, so that the elevation angle of the solar panel 316 can be adjusted quickly and conveniently, and thus can be used better. Furthermore, the bottom of the base plate 1 is connected to the top of the caster wheel 2, the bottom of the bearing plate 301 is connected to the top of the storage box 410, the bottom of the base plate 1 is connected to the top of the electric telescopic rod 401, and the bottom of the base plate 1 is connected to the top of the forward and reverse motor 501.

[0022] The top of the threaded rod 314 is fixed with a circular rotating handle with a diameter of 5cm. The surface of the handle has anti-slip texture, which makes it easy for the operator to manually rotate and apply force. The clamping plate 315 is made of ABS engineering plastic, and the bottom is attached with a silicone cushioning pad with a thickness of 2mm to prevent damage to the surface of the solar panel 316 when squeezed. The top of the placement plate 312 has a positioning groove with a depth of 3mm that matches the bottom of the solar panel 316. The inner wall of the positioning groove is equipped with a rubber strip to enhance the stability of the solar panel when placed and prevent slippage. The limiting holes on the top of the support plate 301 are evenly distributed along the circumference, with 12 holes, one every 30°. The hole diameter is 8mm and the hole depth is 10mm, ensuring that the horizontal angle adjustment accuracy of the solar panel can reach 30°. The fixing bolt 304 is an M8 hex socket head cap bolt with a length of 20mm and is equipped with a spring washer to prevent vibration and loosening. The rotating connection between the movable rod 302 and the support plate 301 uses a deep groove ball bearing of model 6203 to ensure smooth rotation without jamming. The sliding plate 309 and the rotating rod 306 have a clearance fit of 0.1-0.2mm. The spring on one side of the sliding plate 309 is a cylindrical compression spring with a wire diameter of 1mm, a free length of 30mm, and a stiffness coefficient of 5N / mm. In its natural state, it pushes the limiting rod 310 into the adjustment hole. The adjusting holes on one side of the fixed plate 305 are distributed along an arc-shaped trajectory, with eight holes, one every 5°, and a hole diameter of 6mm, ensuring that the elevation angle adjustment range is 0°-40° and the adjustment accuracy is 5°. The guide rod 311 has a diameter of 8mm and a circular limiting block with a diameter of 10mm is installed at the end, which has a clearance fit with the sliding groove of the fixed plate 305 with a width of 10mm to prevent the guide rod from falling off.

[0023] When mowing is required, the operator can push the entire device using the casters 2. To install the solar panel 316, place it into the placement plate 312. Rotating the threaded rod 314 moves it along the inner wall of the limiting plate 313, causing the clamping plate 315 to move and contact the solar panel 316, thus clamping and fixing it in the placement plate 312 for use. To adjust the angle of the solar panel 316, rotate the fixing plate 303 along the inner wall of the movable rod 302. The fixing plate 303 can be pulled out from the top of the support plate 301, releasing the limiting fixation on the movable rod 302. Rotating the placement plate 312 then rotates the solar panel 316, indirectly rotating the movable rod 302, allowing for quick and convenient adjustment of the solar panel's angle. When adjusting the elevation angle of the solar panel 316, the sliding plate 309 is pulled to slide on the outer wall of the rotating rod 306. The sliding plate 309 compresses the spring and moves the limiting rod 310. The limiting rod 310 can be pulled out from one side of the fixed plate 305, thus releasing the limiting fixation of the rotating rod 306. At this time, rotating the rotating plate 308 drives the rotating rod 306 to rotate. The rotation of the rotating rod 306 drives the swing plate 307 to rotate. The rotation of the swing plate 307 drives the guide rod 311 to slide inside the fixed plate 305, thereby increasing the stability of the swing plate 307 during rotation. The rotation of the swing plate 307 drives the placement plate 312 to rotate, and the rotation of the placement plate 312 drives the solar panel 316 to rotate. This allows for quick and convenient adjustment of the elevation angle of the solar panel 316, enabling better adjustment of the position of the solar panel 316 according to the sun's position for better use.

[0024] Example 2: Based on Example 1, the mowing mechanism 4 includes an electric telescopic rod 401, a connecting plate 402, a telescopic rod 403, a mowing device 404, and a connecting rod 405. The bottom of the electric telescopic rod 401 is connected to the top of the connecting plate 402, the top of the connecting plate 402 is connected to the bottom of the telescopic rod 403, the bottom of the connecting plate 402 is connected to the top of the mowing device 404, one side of the connecting plate 402 is connected to one end of the connecting rod 405, and a collection hopper 406 is fixedly installed at the other end of the connecting rod 405. A telescopic rod 407 is fixedly installed at the top of the collection hopper 406. A guide pipe 408 is connected to one side of the collection hopper 406, and a pump 409 is connected to the top of the guide pipe 408. A storage box 410 is fixedly installed at the bottom of the pump 409, and a partition plate 411 is fixedly installed on the inner wall of the storage box 410. In this embodiment, there are two telescopic rods 403, which are symmetrically distributed on the top of the connecting plate 402 and connected to each other. The connecting rod 405 is U-shaped. There are also two telescopic rods 407, which are symmetrically distributed on the top of the collecting hopper 406. The guide pipe 408 is made of a flexible telescopic hose, which enables better mowing of grass at different heights and collection and storage of grass clippings for better use.

[0025] The electric telescopic pole 401 is equipped with a control box (fixed to the side of the base plate 1). The control box has three self-reset buttons: "Up", "Down", and "Stop". It has a built-in L298N motor drive module, which is connected to a 12V battery via wires. The lawn mowing device 404 is a rotary lawn mowing disc with a diameter of 30cm. It has three built-in manganese steel blades with a thickness of 2mm and a length of 12cm. It is driven by a 12V DC motor with an adjustable speed of 1500-3000r / min. The telescopic pole 403 is an aluminum alloy telescopic pole of model TEC16 with a maximum stroke of 50cm and a cylinder diameter of 16mm to ensure that the connecting plate 402 is raised and lowered smoothly. The collection hopper 406 has an opening width matching the diameter of the mowing blade (30cm), an inner wall inclination angle of 45°, and an arc-shaped guide plate at the bottom to guide grass clippings to the inlet of the guide pipe 408. The extraction pump 409 is a 12V DC self-priming pump (flow rate 15L / min), and a stainless steel protective mesh (2mm mesh diameter) is built into its connection with the guide pipe 408 to prevent grass clippings from clogging the pump body. The partition plate 411 inside the storage box 410 is made of PP plastic and is connected to the box wall by clips. It can be disassembled as needed to divide the storage box into a "grass clipping area" (80L capacity) and a "medicine solution area" (50L capacity). Both areas are equipped with drain valves at the bottom.

[0026] When mowing is required, the operator can push the entire device using the casters 2. The solar panel 316 can be quickly and easily installed and removed using the adjustment mechanism 3, and its angle and elevation can be adjusted for better use. When mowing is needed, activating the electric telescopic rod 401 moves the connecting plate 402, which in turn extends the telescopic rod 403, increasing the stability of the connecting plate 402's movement. The movement of the connecting plate 402 moves the mowing device 404, enabling mowing of grass at different heights. The movement of the connecting plate 402 also moves the connecting rod 405, which in turn moves the collection hopper 406. The collection bucket 406 moves, causing the telescopic rod 407 to extend and retract, thus increasing the stability of the collection bucket 406 during movement and allowing it to move synchronously with the mowing equipment 404. This allows grass clippings generated during mowing to enter the collection bucket 406. At this point, activating the extraction pump 409 allows the grass clippings to be collected through the guide pipe 408 and stored in the storage box 410. A protective net is installed between the extraction pump 409 and the guide pipe 408 to effectively protect the extraction pump 409 and prevent damage. A partition plate 411 divides the internal space of the storage box 410, allowing for better mowing operations and enabling the collection and storage of grass clippings for better use.

[0027] Example 3: Based on Example 1, the spraying mechanism 5 includes a forward and reverse motor 501, a rotating rod 502, a stirring rod 503, an electric telescopic rod 504, and a mounting plate 505. The output end of the forward and reverse motor 501 is connected to the bottom of the rotating rod 502. The outer wall of the rotating rod 502 is connected to the inner wall of the stirring rod 503. The top of the base plate 1 is connected to the bottom of the electric telescopic rod 504. The top of the electric telescopic rod 504 is connected to the bottom of the mounting plate 505. An adjusting plate 506 is fixedly installed on one side of the mounting plate 505. A guide plate 507 is slidably connected to one end of the adjusting plate 506. One end of the water pump 508 is connected to the inner wall of the storage tank 410. A water guide pipe 509 is connected to one end of the water pump 508. A nozzle 510 is connected to one end of the water guide pipe 509. In this embodiment, there are several stirring rods 503, which are symmetrically distributed on the outer wall of the rotating rod 502. A moving groove is provided on one side of the guide plate 507, and one end of the adjusting plate 506 is slidably connected to the inner wall of the moving groove. There are several spray nozzles 510, which are symmetrically distributed on one side of the mounting plate 505. This allows for quick and convenient mixing of the medicine and water, and quick and convenient spraying of the medicine, thus enabling better use.

[0028] The forward and reverse motor 501, model 57BYG250-150, has a rated voltage of 12V and a speed of 150r / min. It is connected to the rotating rod 502 via a coupling. The stirring rod 503 is made of stainless steel (8mm in diameter), 15cm in length, and is arranged in groups of three every 10cm along the axis of the rotating rod 502, symmetrically distributed at 120° to ensure uniform mixing of the medicine. The top of the medicine storage tank 410 has a filling port (10cm in diameter) with a sealing cap to prevent splashing of the medicine during stirring. The guide plate 507 is bolted to the top of the base plate 1. A PTFE wear-resistant layer is adhered to the inner wall of its moving groove. The adjusting plate 506 has a clearance fit with the moving groove (0.5mm), and a limiting protrusion at the end prevents slippage. The electric telescopic rod 504, model TEC20, has a maximum stroke of 40cm and can drive the nozzle 510 to adjust its height within a range of 30-70cm. The water pump 508 is a 12V miniature diaphragm pump with a flow rate of 8L / min. The inlet is connected to the storage tank 410 via a filter. The water guide pipe 509 is a PVC reinforced flexible hose with an inner diameter of 10mm and a length of 2m. The nozzle 510 is a rotary atomizing nozzle with a spray angle of 60°. There are six nozzles, evenly distributed laterally along the mounting plate 505 at 15cm intervals. The atomized particle size can be adjusted from 50-100μm by adjusting the nozzle knob.

[0029] When mowing is required, the operator can push the entire device using the casters 2. The solar panel 316 can be quickly and easily installed and removed using the adjustment mechanism 3, and its angle and elevation can be adjusted for better use. When mowing is needed, the mowing mechanism 4 can be activated to mow grass of different heights, and grass clippings can be collected and stored during the mowing process. At this time, the pesticide and water are poured into the storage tank 410. Activating the forward and reverse motor 501 drives the rotating rod 502 to rotate, which in turn drives the stirring rod 503 to rotate, thus mixing the pesticide and water. Once the mixture is properly stirred, the water pump 508 is activated to transport the liquid medicine inside the storage tank 410 to the nozzle 510 through the water pipe 509. The nozzle 510 then sprays the liquid medicine onto the lawn for better application. When the height of the nozzle 510 needs to be adjusted, the electric telescopic rod 504 is activated to move the mounting plate 505. The movement of the mounting plate 505 causes the adjusting plate 506 to slide inside the guide plate 507, thereby increasing the stability of the mounting plate 505 during movement. The movement of the mounting plate 505 also moves the nozzle 510, allowing for quick and convenient adjustment of the nozzle 510's height and increasing its spraying range for better application.
