Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of lawn mowers, and particularly to a highly adaptable lawn mower suitable for uneven ground. Background Art
[0002] A lawn mower is a mechanical device used for trimming lawns and vegetation, and is widely used in fields such as home gardens, public green spaces, golf courses, and agricultural plantings. With the development of technology, lawn mowers have continuously advanced in terms of efficiency, environmental protection, and intelligence, becoming an important tool for modern garden maintenance;
[0003] During the process of a lawn mower trimming a lawn green space, due to the dense and uneven distribution of vegetation, the vision of the lawn mower operator is severely blocked, making it difficult to accurately judge the flatness of the ground. When the lawn mower travels to a place with a large difference in ground unevenness, it is very easy to cause the lawn mower to tilt during operation, resulting in the contact of the blades at the bottom of the lawn mower. The high-speed rotating blades will not only bend, notch, or even break due to uneven force, reducing the cutting efficiency, accelerating blade wear, shortening its service life, thereby increasing the maintenance cost of the lawn mower, but also when the blades collide with the ground, they will stir up the soil and gravel on the ground and cause splashing, causing harm to the staff or surrounding personnel, increasing the danger of the lawn mower during operation, and when the blades contact the ground during high-speed rotation to cut the vegetation, it will cause uneven cutting of the vegetation at least, leaving uncut or cut grass marks, affecting the overall beauty of the lawn, and at worst, it will damage the lawn roots, resulting in local yellowing or death of the lawn.

[0018] (III) Beneficial effects
[0019] Compared with the prior art, the present invention provides a highly adaptable mower suitable for uneven ground, and has the following beneficial effects:
[0020] 1. Through the set ground flatness monitoring mechanism, it can monitor the driving path of the mobile vehicle body, and when there is a large difference in unevenness on the ground, it will trigger the alarm light to flash in time to remind the staff to control the mobile vehicle body to avoid, thus preventing the mower body installed on the mobile vehicle body from contacting the ground. This not only prevents the blades on the mower body from bending, chipping or even breaking due to collision with the ground, maintains the cutting efficiency, slows down the blade wear, extends the service life, reduces the maintenance cost, but also avoids the splashing of soil and gravel when the blade collides with the ground, reduces the risk of harm to the staff or surrounding personnel, reduces the danger during the working process of the mower body, and can ensure uniform cutting of vegetation, avoid leaving uncut or cut grass marks, improve the overall aesthetics of the lawn, and at the same time prevent damage to the lawn roots and avoid local yellowing or death of the lawn.
[0021] 2. Through the set slide plate, linkage frame, moving plate, limiting groove and linkage block, after the mobile vehicle body and the mower body are used, it can push the lifting column to rise automatically to drive the rollers to separate from the ground, thereby reducing the usage time of the rollers, reducing the wear of the rollers and their bearings, extending the service life of the rollers, and reducing the maintenance labor and parts cost.
[0022] 3. Through the set mowing anomaly warning mechanism, when the temperature generated during the operation of the lawn mower body is too high, the alarm can be automatically turned on to work, timely reminding the staff to pause the operation of the lawn mower body. This not only eliminates the subjective experience error of the staff, ensures that the alarm is triggered immediately when the temperature of the lawn mower body reaches the preset threshold, avoids irreversible damage caused by overheating of the battery, thereby prolonging the life of the lawn mower body, but also enables the staff to scientifically arrange rest intervals based on the alarm instead of operating blindly, thus improving the overall efficiency of the mowing operation;
[0023] Among them, through the set two-way nickel-titanium alloy wire, during the downtime and rest period of the lawn mower body, as the temperature of the lawn mower body drops to the low-temperature phase of the two-way nickel-titanium alloy wire, the lifting block will drive the pointer to descend synchronously. When the staff observes the pointer moving to the display board area, they can turn on the lawn mower body to work again. There is no need for the staff to sense the temperature of the lawn mower body by approaching or touching, avoiding the risk of scalding the staff and further ensuring the safety of the staff during the work process.
[0024] 4. Through the set connecting frame and scraper, during the warning process when the temperature of the lawn mower body is too high, the heat dissipation holes opened on the side wall of the lawn mower body can be cleaned synchronously. This not only ensures that the heat dissipation holes are unobstructed, enables the heat generated inside the lawn mower body to be dissipated more quickly, thereby effectively reducing the temperature of the lawn mower body, but also cleaning the heat dissipation holes helps to shorten the downtime and rest time of the lawn mower body affected by high temperature, reduce frequent shutdowns caused by overheating, and enable the mowing operation to proceed continuously.

[0036] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.
[0037] A highly adaptable lawn mower applicable to uneven ground in this embodiment, as Figure 1 - Figure 7 shown, includes a moving vehicle body 1, a lawn mower body 2 is fixedly connected to the moving vehicle body 1, heat dissipation holes 3 are symmetrically opened on the outer surface of the lawn mower body 2, a fixing plate 4 is fixedly connected to the front side of the moving vehicle body 1, and further includes a ground flatness monitoring mechanism and a mowing abnormality warning mechanism. The ground flatness monitoring mechanism includes equally spaced lifting columns 501, the lifting columns 501 are all slidably connected through the fixing plate 4, and rollers 502 are fixedly connected to the lower ends of the lifting columns 501. The ground flatness monitoring mechanism is used to monitor the ground slope of the driving path of the moving vehicle body 1.
[0038] In this embodiment, as Figure 5As shown in the figure, hollow boxes 503 are fixedly connected to the upper end surface of the fixed plate 4 at equal intervals. The number of hollow boxes 503 is the same as that of the lifting columns 501. The lifting columns 501 all penetrate and are slidably connected inside the hollow boxes 503. Through slots 509 are opened on the side walls of the hollow boxes 503. Connecting blocks 516 are fixedly connected to the upper ends of the lifting columns 501. The connecting blocks 516 are all slidably connected inside the hollow boxes 503. Pressing plates 510 are fixedly connected to one side of the connecting blocks 516 close to the through slots 509. The pressing plates 510 are all slidably connected inside the through slots 509. When the lifting columns 501 move up and down, they will push the connecting blocks 516 to rise and fall synchronously inside the hollow boxes 503, and drive the pressing plates 510 to slide up and down inside the through slots 509. And through the equidistant arrangement of the lifting columns 501, it can prevent larger stones from passing through the lifting columns 501 and contacting the blades at the lower end of the lawn mower body 2.
[0039] In this embodiment, as Figure 3 and Figure 5 shown, fixing blocks 511 are symmetrically and fixedly connected to one side of the hollow boxes 503 close to the through slots 509. Buttons 512 are fixedly connected to one side of the fixing blocks 511 close to the pressing plates 510. Alarm lights 513 are fixedly connected to the upper end surfaces of the hollow boxes 503. The buttons 512 are all electrically connected to the alarm lights 513. When the up and down movement amplitude of the pressing plate 510 is too large, it will contact the button 512 and press the button 512 to turn on the alarm light 513 to flash.
[0040] In this embodiment, as Figure 2 shown, support columns 506 are symmetrically and fixedly connected to one side of the fixed plate 4 away from the moving vehicle body 1. A sliding plate 517 is slidably connected between the outer surfaces of the two support columns 506. Linkage frames 507 are symmetrically and fixedly connected to the lower end surface of the sliding plate 517. A moving plate 508 is fixedly connected between one side of the two linkage frames 507 away from the sliding plate 517. When the sliding plate 517 is pushed to slide on the outer surface of the support column 506, through the arranged linkage frames 507, the moving plate 508 can be driven to move synchronously.
[0041] In this embodiment, as Figure 4 shown, a limiting groove 514 is opened on one side of the moving plate 508 close to the lifting column 501. Linkage blocks 515 are fixedly connected to the outer surfaces of the lifting columns 501. One side of the linkage blocks 515 close to the limiting groove 514 is an inclined surface. When the moving plate 508 approaches the linkage block 515, it will first contact the inclined surface, and then as the moving plate 508 continues to move, the moving plate 508 will push the linkage block 515 to rise through the inclined surface until the linkage block 515 is stuck into the limiting groove 514 opened on the side wall of the moving plate 508 to fix the height of the linkage block 515.
[0042] In this embodiment, as Figure 2As shown in the figure, a threaded rod 504 is connected through the center of the skateboard 517. The threaded rod 504 is rotatably connected to the side wall of the fixing plate 4. One end of the threaded rod 504 away from the fixing plate 4 is fixedly connected with a knob 505. When the knob 505 is rotated to drive the threaded rod 504 to rotate, the skateboard 517 can be driven to move on the surface of the threaded rod 504 through the threaded connection between the threaded rod 504 and the skateboard 517.
[0043] In the prior art, when the lawn mower travels to a place with large differences in ground unevenness, it is very easy to cause the lawn mower to tilt during operation, causing the blades at the bottom of the lawn mower to come into contact. The high-speed rotating blades will not only bend, notch or break due to uneven force, reducing the cutting efficiency, accelerating blade wear and shortening its service life, thus increasing the maintenance cost of the lawn mower. Moreover, when the blades collide with the ground, they will stir up the soil and gravel on the ground and cause splashing, causing harm to the staff or surrounding people, increasing the danger of the lawn mower during operation. And when the blades rotate at high speed and contact the ground to cut the vegetation, it will either cause uneven cutting of the vegetation, leaving uncut or cut grass marks, affecting the overall beauty of the lawn, or damage the root system of the lawn, resulting in local yellowing or death of the lawn. Compared with the prior art, it can monitor the driving path of the moving vehicle body 1, and when the ground unevenness difference is too large, the warning light 513 will be triggered in time to flash, reminding the staff to control the moving vehicle body 1 to avoid, thus preventing the lawn mower body 2 installed on the moving vehicle body 1 from contacting the ground. This not only prevents the blades on the lawn mower body 2 from bending, notching or breaking due to collision with the ground, maintains the cutting efficiency, slows down blade wear, extends the service life and reduces the maintenance cost, but also avoids the splashing of soil and gravel when the blades collide with the ground, reduces the risk of harm to the staff or surrounding people, reduces the danger of the lawn mower body 2 during operation, and can ensure even cutting of the vegetation, avoid leaving uncut or cut grass marks, improve the overall beauty of the lawn, and at the same time prevent damage to the root system of the lawn and avoid local yellowing or death of the lawn.
[0044] On other levels, this embodiment also provides a mowing abnormal warning mechanism for reminding the staff to pause in time when the temperature of the lawn mower body 2 is abnormal, such as Figure 1 、 Figure 6 and Figure 7As shown in the figure, the abnormal mowing warning mechanism includes a telescopic column 605. The telescopic column 605 is fixedly connected to the upper end surface of the moving vehicle body 1 near the mower body 2. The upper end of the telescopic column 605 is fixedly connected with a lifting block 601. A two-way nickel-titanium alloy wire 606 is fixedly connected between the lower end surface of the lifting block 601 and the upper end surface of the moving vehicle body 1. A support block 602 is arranged at the upper end of the lifting block 601. The support block 602 is fixedly connected to the outer surface of the mower body 2. An alarm 603 is fixedly connected to the upper end surface of the support block 602. A switch 604 is fixedly connected to the lower end surface of the support block 602. The alarm 603 and the switch 604 are electrically connected. The switch 604 and the lifting block 601 are located on the same vertical line.
[0045] In this embodiment, as Figure 6 shown in the figure, connecting frames 607 are fixedly connected to both sides of the lifting block 601. Scrapers 608 are fixedly connected to the ends of the connecting frames 607 far away from the lifting block 601. The scrapers 608 are all in contact with the heat dissipation holes 3. When the lifting block 601 moves up and down, the connecting frames 607 can drive the scrapers 608 to move synchronously in contact with the heat dissipation holes 3 to clean the heat dissipation holes 3.
[0046] In this embodiment, as Figure 7 shown in the figure, a pointer 609 is fixedly connected to the side of the lifting block 601 close to the mower body 2. A display board 610 is fixedly connected to the outer surface of the mower body 2. The initial position of the pointer 609 is at the display board 610. During the process of the staff stopping and resting the mower body 2, by observing whether the pointer 609 moves to the display board 610, it can be judged whether the temperature of the mower body 2 reaches the requirement for continuous operation.
[0047] In the prior art, when workers use a lawn mower for a long time, it is easy for the lawn mower to overheat. In a high-temperature environment, the battery of the lawn mower is prone to overheating, resulting in shortened battery life or direct damage. At this time, the worker needs to stop for a break. In the actual use process, the worker judges the temperature of the lawn mower based on experience. It is not only difficult to accurately perceive the actual temperature of the equipment. When the lawn mower works in a high-temperature environment for a long time, key components such as the battery will be damaged due to overheating. However, the worker continues to use it because they fail to detect the abnormal temperature in time, resulting in equipment damage. Moreover, the judgment based on experience lacks a clear quantitative standard, and different workers have different perceptions of "high temperature". This inconsistency in subjective judgment causes the lawn mower to be damaged to varying degrees in different usage scenarios. Compared with the prior art, when the temperature generated during the operation of the lawn mower body 2 is too high, the alarm 603 can be automatically turned on to work, timely reminding the worker to pause the operation of the lawn mower body 2. This not only eliminates the subjective experience error of the worker, ensures that the alarm is triggered immediately when the temperature of the lawn mower body 2 reaches the preset threshold, avoids irreversible damage caused by battery overheating, thereby prolonging the life of the lawn mower body 2, but also allows the worker to scientifically arrange the rest interval according to the alarm instead of operating blindly, thereby improving the overall efficiency of the lawn mowing operation;
[0048] Among them, through the set bi-directional nickel-titanium alloy wire 606, during the break of the lawn mower body 2, as the temperature of the lawn mower body 2 drops to the low-temperature phase of the bi-directional nickel-titanium alloy wire 606, it will drive the pointer 609 to synchronously drop through the lifting block 601. When the worker observes the pointer 609 moving to the display board 610 area, they can turn on the lawn mower body 2 to work again. There is no need for the worker to perceive the temperature of the lawn mower body 2 by approaching or touching, avoiding the risk of scalding the worker and further ensuring the safety of the worker during the work process.
[0049] The working process and principle involved in the overall content of the above embodiment are as follows:
[0050] It should be noted that: The two-way nickel-titanium alloy wire 606 (also known as two-phase alloy or two-shape memory alloy) is a type of alloy material with a special shape memory effect. It can achieve two different shapes at different temperatures. The most common two-way memory effect alloy is the nickel-titanium alloy (Ni-Ti alloy), also known as the "Nitinol" alloy or "superelastic alloy". It usually has the following two shapes: high-temperature phase and low-temperature phase. At the high-temperature phase (usually above room temperature), the material is in an elastic shape and can undergo large elastic deformations. While at the low-temperature phase (usually below room temperature), the material will return to the pre-set initial shape. Specifically, the transformation temperature (two-way transformation temperature) of the nickel-titanium alloy (Ni-Ti alloy) can be adjusted according to the composition and treatment of the alloy. Usually, the high-temperature phase transformation temperature range is about 40 - 100 °C, and the low-temperature phase transformation temperature range is about -10 to 30 °C. This range can be adjusted according to the specific application requirements. It should be noted that the shape memory process of the two-way memory effect alloy is reversible and can be switched between high temperature and low temperature multiple times while maintaining the same memory effect. In this embodiment, the low-temperature phase of the two-way nickel-titanium alloy wire 606 is in a contracted state, and the high-temperature phase will automatically extend.
[0051] When the staff pushes the mobile vehicle body 1 to drive the lawn mower body 2 to trim the lawn, as the mobile vehicle body 1 moves, the roller 502 provided in front of the mobile vehicle body 1 will first roll on the mowing path. When the mowing path is uneven, the roller 502 will synchronously push the lifting column 501 to slide up and down on the fixing plate 4 during the movement. When the undulation amplitude of the ground of the mowing path is too large, the roller 502 will push the lifting column 501 to drive the connecting block 516 to move up and down synchronously in the hollow box 503. Since the pressing plate 510 is connected to the side wall of the hollow box 503 and the pressing plate 510 is slidably connected in the through groove 509, and buttons 512 are provided above and below the pressing plate 510, during the up and down movement of the connecting block 516 in the hollow box 503, the pressing plate 510 will be driven to lift and lower synchronously in the through groove 509. And when the up and down movement amplitude of the pressing plate 510 is too large, the button 512 provided above or below will be pressed. Through the electrical connection between the button 512 and the alarm lamp 513, the alarm lamp 513 installed at the upper end of the hollow box 503 is turned on to flash, reminding the staff that the ground slope at a certain place is too large, and pushing the mobile vehicle body 1 to drive the lawn mower body 2 to avoid, thus preventing the lawn mower body 2 installed on the mobile vehicle body 1 from contacting the ground. This not only prevents the blades on the lawn mower body 2 from bending, chipping or even breaking due to collision with the ground, maintains the cutting efficiency, slows down the blade wear, extends the service life and reduces the maintenance cost, but also avoids the splashing of soil and gravel when the blades collide with the ground, reduces the risk of harm to the staff or surrounding personnel, reduces the danger during the working process of the lawn mower body 2, and can ensure uniform cutting of the vegetation, avoid leaving uncut or cut grass marks, improve the overall aesthetics of the lawn, and at the same time prevent damage to the lawn roots and avoid local yellowing or death of the lawn;
[0052] During the continuous operation of the lawn mower body 2, the lawn mower body 2 will generate high temperature. The high temperature will be transmitted through the air and come into contact with the two-way nickel-titanium alloy wire 606 set near the lawn mower body 2. When the high temperature reaches the critical value of the two-way nickel-titanium alloy wire 606, it will cause the two-way nickel-titanium alloy wire 606 to undergo a high-temperature phase deformation, pushing the lifting block 601 to rise and pulling the telescopic column 605 connected to the lower end of the lifting block 601 to extend. During the rising process of the lifting block 601, since there is a switch 604 above the lifting block 601 and the switch 604 is electrically connected to the alarm 603, as the lifting block 601 rises, it will gradually approach the switch 604 and press the switch 604 to turn on the alarm 603 to work, reminding the staff that the temperature of the lawn mower body 2 is abnormal and needs to be shut down and repaired in time. This not only eliminates the subjective experience error of the staff, ensures that the alarm is triggered immediately when the temperature of the lawn mower body 2 reaches the preset threshold, avoids irreversible damage caused by overheating of the battery, and thus extends the life of the lawn mower body 2, but also allows the staff to scientifically arrange rest intervals according to the alarm instead of operating blindly, thereby improving the overall efficiency of the mowing operation;
[0053] During the rising process of the lifting block 601, since connecting frames 607 are installed on both sides of the lifting block 601, and scraping plates 608 are connected to the sides of the connecting frames 607 far away from the lifting block 601, and the scraping plates 608 are in contact with the heat dissipation holes 3, as the lifting block 601 rises, through the set connecting frames 607, the scraping plates 608 can be driven to move upward in synchronization with the heat dissipation holes 3, so that the scraping plates 608 clean the surfaces of the heat dissipation holes 3. This not only ensures that the heat dissipation holes 3 are unobstructed, enables the heat generated inside the lawn mower body 2 to be dissipated more quickly, and thus effectively reduces the temperature of the lawn mower body 2, but also cleaning the heat dissipation holes 3 helps to shorten the time for the lawn mower body 2 to be shut down and repaired due to the influence of high temperature, reduces frequent shutdowns caused by overheating, and enables the mowing operation to be carried out continuously;
[0054] During the shutdown and repair process of the lawn mower body 2, as the temperature of the lawn mower body 2 drops, the air temperature near the lawn mower body 2 will also drop to normal temperature synchronously. At this time, the two-way nickel-titanium alloy wire 606 will trigger the low-temperature phase and automatically pull the lifting block 601 to descend, causing the lifting block 601 to push the telescopic column 605 connected to the lower end to contract. During the descending process of the lifting block 601, the lifting block 601 will drive the pointer 609 connected to the side wall to descend synchronously. The staff can observe whether the pointer 609 descends to the area of the display board 610 installed on the side wall of the lawn mower body 2 to judge whether the temperature of the lawn mower body 2 meets the requirement for restarting. There is no need for the staff to sense the temperature of the lawn mower body 2 by approaching or touching it, avoiding the risk of scalding the staff and further ensuring the safety of the staff during the work process;
[0055] When the mowing operation of the mower body 2 is completed, the mower body 2 is pushed to a horizontal ground by moving the vehicle body 1. Then, the staff can rotate the knob 505 to drive the threaded rod 504 to rotate. Since the threaded rod 504 is threadedly connected to the slide plate 517, the slide plate 517 can be pushed to move towards the fixed plate 4 on the outer surface of the threaded rod 504 and horizontally slide between the outer surfaces of the support columns 506. As the slide plate 517 moves, since the linkage frame 507 is installed on the lower end surface of the slide plate 517 and the moving plate 508 is connected between the linkage frames 507, the slide plate 517 will drive the moving plate 508 to move horizontally synchronously and approach the lifting column 501 during the movement. Since the linkage block 515 is connected to the outer surface of the lifting column 501 and the side of the linkage block 515 close to the moving plate 508 is an inclined surface, when the moving plate 508 approaches the linkage block 515, it will first contact the inclined surface of the linkage block 515 and push the linkage block 515 to rise through the inclined surface until the linkage block 515 is caught in the limiting groove 514 opened on the moving plate 508. During the rising process of the linkage block 515, the linkage block 515 will drive the lifting column 501 to rise synchronously and pull the roller 502 connected to the lower end of the lifting column 501 away from the ground, thereby reducing the usage time of the roller 502, reducing the wear of the roller 502 and its bearing, extending the service life of the roller 502, and reducing the maintenance labor and parts cost.
