Detailed Implementation

[0034] The following are specific implementation cases and appendices. Figure 1-12 The present invention will be further described, but the present invention is not limited to these embodiments.

[0035] A smart remote-controlled obstacle-avoiding lawnmower, such as Figure 1-12 As shown, the device includes: a frame 1, two first electric push rods 4, a second electric push rod 5, a height adjustment mechanism, a connecting frame 7, a hay-pulling device, a reciprocating cutter, an automatic baling device, an obstacle avoidance device, and a remote control receiver 42; the frame 1 is equipped with a power drive unit, an engine 2, and a generator 3; the two first electric push rods 4 are hinged to both sides of the frame 1; the second electric push rod 5 is hinged to one side of the frame 1; the height adjustment mechanism includes two slider guide rail assemblies 6 and a belt tensioning device, the two slider guide rail assemblies 6 are respectively located on both sides of the frame 1, the telescopic ends of the two first electric push rods 4 are respectively connected to the moving ends of the two slider guide rail assemblies 6, and the belt tensioning device is respectively connected to the moving ends of the two slider guide rail assemblies 6. The moving end of the connecting frame 7 is connected to the slider guide rail assembly 6, and the belt tensioning device is hinged to the telescopic end of the second electric push rod 5; the two ends of the connecting frame 7 are respectively connected to the two slider guide rail assemblies 6; the grass-pulling device is set on the connecting frame 7 and the reciprocating cutter is set on the connecting frame 7; the automatic baling device is set on one side of the connecting frame 7; the obstacle avoidance device includes a GPS positioning module 43, an ultrasonic module 44 and a laser radar 45 module. The ultrasonic module 44 is installed at the four positions of the left front, left rear, right front and right rear of the frame 1, and the laser radar 45 module is installed on the top of the frame 1 as a rear obstacle avoidance module; the remote control receiver 42 is set on the frame 1 and controls the operation of the first electric push rod 4 and the second electric push rod 5.

[0036] The above structure, using a reciprocating cutter and a height adjustment mechanism, increases the mowing range, prevents the equipment from crushing weeds during movement, and facilitates timely adjustment of the stubble height. After cutting the weeds, the reciprocating cutter conveys them to an automatic baling device for bundling, allowing for reuse. The system utilizes a GPS positioning module 43, an ultrasonic module 44, and a lidar module 45. The ultrasonic module 44 detects obstacles in four directions: left front, left rear, right front, and right rear. The lidar module 45 generates a density map based on the real-time location information. When the ultrasonic module 44 detects an obstacle, the system uses the density map detected by the lidar module 45 to determine the mower's next action, ensuring safe operation.

[0037] Specifically, the output of the first electric push rod 4 and the second electric push rod 5 are controlled by the remote control receiver 42, thereby achieving the purpose of remotely operating the height of the reciprocating cutter and adjusting the belt tensioning device.

[0038] Specifically, the present invention can perform path planning through software and use GPS positioning module 43 in combination with ultrasonic module 44 and lidar module 45 to ensure that the lawnmower can operate independently. It is also equipped with a remote control device, which allows the operator to control it at any time, thereby ensuring the safety of staff and equipment.

[0039] Specifically, remote control always takes precedence over automatic control.

[0040] Specifically, the LiDAR 45 module, as a rear-stage obstacle avoidance module, is installed directly above the vehicle frame 1 to ensure 360-degree real-time location information collection without blind spots and generate a visual image.

[0041] In embodiments of the present invention, such as Figure 1-12 As shown, the belt tensioning device includes: a first rotating shaft 8, a first pulley 9, a second rotating shaft 10, a second pulley 11, a belt tensioning bracket 12, a belt tensioning wheel 13, and a first belt 14; both ends of the first rotating shaft 8 are connected to the moving ends of the two slider guide rail assemblies 6 through two first bearing brackets respectively; the first pulley 9 is sleeved on the outside of the first rotating shaft 8; both ends of the second rotating shaft 10 are connected to the two sides of the frame 1 through two second bearing brackets respectively, and the second rotating shaft 10 is connected to the engine 2; the second pulley 11 is sleeved on the outside of the second rotating shaft 10; one end of the belt tensioning bracket 12 is hinged to the telescopic end of the second electric push rod 5, and one end of the belt tensioning bracket 12 is hinged to the frame 1; the belt tensioning wheel 13 is disposed on the belt tensioning bracket 12; the first belt 14 is simultaneously wound around the outside of the first pulley 9, the second pulley 11, and the belt tensioning wheel 13.

[0042] By ensuring a linear complementary relationship between the first electric push rod 4 and the second electric push rod 5, the belt tensioner 13 can be adjusted in a timely manner while the reciprocating cutter rises, ensuring sufficient friction between the first pulley 9 and the second pulley 11, thereby reducing power loss.

[0043] In embodiments of the present invention, such as Figure 1-12 As shown, the grass-removing device includes: a first belt roller shaft 15, a second belt roller shaft 16, a grass-removing belt 17, a right-angle gearbox 18, a third rotating shaft 19, a third pulley 20, a fourth pulley 21, and a second belt 22; the first belt roller shaft 15 is disposed on one side of the connecting frame 7; the second belt roller shaft 16 is disposed on the other side of the connecting frame 7; the grass-removing belt 17 is provided with a paddle, and the grass-removing belt 17 is simultaneously wound around the outside of the first belt roller shaft 15 and the second belt roller shaft 16; the right-angle gearbox 18 is disposed on the moving end of one of the slider guide rail assemblies 6, and the input end of the right-angle gearbox 18 is connected to the first rotating shaft 8; the third rotating shaft 19 is connected to the output end of the right-angle gearbox 18; the third pulley 20 is sleeved on the outside of the third rotating shaft 19; the fourth pulley 21 is sleeved on the outside of the first belt roller shaft 15; the second belt 22 is simultaneously wound around the outside of the third pulley 20 and the fourth pulley 21.

[0044] The power of the engine 2 is transmitted to the right-angle gearbox 18 via the first belt 14, and then to the third pulley 20 and the fourth pulley 21 via the second belt 22. This enables the grass-pulling belt 17 to drive along the first belt roller shaft 15 and the second belt roller shaft 16, thereby achieving the purpose of smoothly transporting the cut grass to the automatic baling device.

[0045] In embodiments of the present invention, such as Figure 1-12 As shown, the reciprocating cutter includes: a slide groove 23, a cutter 24, a helical gearbox 25, a fourth rotating shaft 26, an eccentric wheel 27, and a connecting rod 28; the slide groove 23 is disposed through the connecting frame 7; the cutter 24 is embedded in the slide groove 23; the helical gearbox 25 is disposed on the connecting frame 7, and the input end of the helical gearbox 25 is connected to the second belt roller shaft 16; the fourth rotating shaft 26 is connected to the output end of the helical gearbox 25; the eccentric wheel 27 is sleeved on the outside of the fourth rotating shaft 26, and a shaft pin is provided on the eccentric wheel 27; one end of the connecting rod 28 is rotatably connected to the cutter 24, and the other end of the connecting rod 28 is rotatably connected to the shaft pin of the eccentric wheel 27.

[0046] By starting the engine 2, the power of the engine 2 is transmitted to the generator 3 and the second shaft 10 respectively to prepare for the operation of the cutter 24. Then, the power is transmitted to the first shaft 8 through the first belt 14, thereby driving the right-angle gearbox 18 to operate. Then, the first belt roller shaft 15 and the grass-removing belt 17 are driven through the third pulley 20 and the fourth pulley 21, thereby enabling the second belt roller shaft 16 to provide power to the helical gearbox 25. Through the cooperation of the eccentric wheel 27 and the connecting rod 28, the circular motion is converted into reciprocating linear motion, driving the cutter 24 to slide along the slide groove 23.

[0047] Specifically, the grass is cut by driving the cutter 24 to move back and forth, thereby increasing the range of grass cutting operations.

[0048] In embodiments of the present invention, such as Figure 1-12 As shown, the automatic baling device includes: an intermittent gearbox 29, a fifth rotating shaft 30, a rope threading wheel 31, a baling rope bracket 32, a knotter 33, two pressure bar brackets 34, a pressure bar 35, and a grass-removing wheel 36; the intermittent gearbox 29 is mounted on the connecting frame 7, and the input end of the intermittent gearbox 29 is connected to the first belt roller shaft 15; one end of the fifth rotating shaft 30 is connected to the output end of the intermittent gearbox 29, and the other end of the fifth rotating shaft 30 is mounted on the connecting frame 7; the rope threading wheel 31 is provided with a baling needle 47, and the rope threading wheel 31 is sleeved on the outside of the fifth rotating shaft 30; the baling rope bracket 32 ​​is mounted on one side of the connecting frame 7, and the baling rope bracket 32 ​​is wound with baling rope 46; the knotter 33 is mounted on the connecting frame 7; the two pressure bar brackets 34 are respectively mounted on the connecting frame 7; the pressure bar 35 is connected to the pressure bar bracket 34; the grass-removing shaft is mounted on the connecting frame 7; and the grass-removing wheel 36 is sleeved on the outside of the fifth rotating shaft 30.

[0049] Power is output to the fifth shaft 30 via the intermittent gearbox 29, controlling the fifth shaft 30 to deflect 120 degrees. The grass-pulling wheel 36 at the fifth shaft 30 rotates, conveying the bundled grass for subsequent collection. At the same time as the grass-pulling wheel 36 is working, the rope-threading wheel 31 and the baling needle 47 work, bringing the baling rope 46 that has passed through the rope threader 48 to the knotter 33 through the baling needle 47, completing the two actions of knotting and cutting the rope, thereby achieving the purpose of automatic baling of grass.

[0050] Specifically, the fifth pivot 30 is a hollow pivot, which makes it easier for the bundling rope 46 to be threaded into the fifth pivot 30 through the rope threader 48.

[0051] In embodiments of the present invention, such as Figure 1-12As shown, it also includes: a power distribution box 37, a battery pack 38, and a work indicator light 39; the power distribution box 37 is mounted on the frame 1, and the power distribution box 37 is equipped with a microcontroller control module, a voltage conversion module, a temperature control module, and a fault alarm module; the battery pack 38 is mounted on the frame 1; wherein, the engine 2 is connected to the generator 3, and the output end of the generator 3 is connected to the power distribution box 37 through a wire, thereby replenishing the energy of the battery pack 38.

[0052] The power drive unit provides energy for the lawnmower. The engine 2 drives the reciprocating blades to operate, and the battery pack 38 drives the drive wheels forward. While mowing, the engine 2 also charges the battery pack 38, thereby improving the device's range.

[0053] Specifically, a cooling fan is provided on the left side of the distribution box 37 to reduce the temperature of the electronic components in the distribution box 37 in a timely manner, so as to ensure that the components are not damaged.

[0055] The drive motor uses a 4*250W geared motor, and there is a rigid connection between the tire and the drive motor shaft to ensure direct power transmission.

[0056] Specifically, the frame 1 is equipped with LED lighting units, which are symmetrically distributed and face directly forward, making them suitable for nighttime operations.

[0057] In embodiments of the present invention, such as Figure 1-12 As shown, it also includes: a pressure sensor 40; the pressure sensor 40 is mounted on the connecting bracket 7.

[0058] Pressure signal is detected by pressure sensor 40. When the pressure signal reaches the set value, a weak pulse signal is generated. The weak pulse signal is converted into a standard current signal of 4-20mA by the transmitter, thereby driving the servo motor to work. The servo motor arm is connected to the control lever of the intermittent gearbox 29 through the connecting rod 28. When the servo motor moves, the control lever of the intermittent gearbox 29 will also move accordingly. Whenever a pulse signal is detected, the output shaft of the intermittent gearbox 29 will deflect 120 degrees, thereby driving the hay-reeling wheel 36 to transfer hay to the right side of the mower.

[0059] In embodiments of the present invention, such as Figure 1-12 As shown, it also includes: a bottom baffle 41; the bottom baffle 41 is installed below the grass-removing belt 17.

[0060] By setting a bottom baffle 41, the phenomenon of straw leakage is avoided, thereby enabling the straw to be collected as thoroughly as possible.

[0061] Implementation Process: The reciprocating cutter and height adjustment mechanism work together to increase the mowing range, preventing the equipment from crushing weeds during movement and facilitating timely adjustment of the stubble height. After cutting the weeds, the reciprocating cutter conveys them to an automatic baling device for bundling, allowing for reuse. The system utilizes a combination of GPS positioning module 43, ultrasonic module 44, and lidar module 45. The ultrasonic module 44 detects obstacles in four directions: left front, left rear, right front, and right rear. The lidar module 45 generates a density map based on the real-time location information. When the ultrasonic module 44 detects an obstacle, the system uses the density map detected by the lidar module 45 to determine the mower's next action, ensuring safe operation.
