[0041] The lawnmower provided in the embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0042] Please see Figure 1 , Figure 2 The lawnmower provided by this utility model includes a main body 1, a drive wheel 2, and a steering wheel 3. Specifically, as... Figure 1 As shown, the main body 1 of the device can be designed as circular or square, etc., and its shape and size can be determined according to actual usage requirements. For example... Figure 2 As shown, a pair of drive wheels 2 are rotatably mounted on the bottom rear end of the device body 1. Specifically, the pair of drive wheels 2 are symmetrically arranged on the bottom rear end of the device body 1 to propel the device body 1, thereby enabling automatic movement on the grass to complete the mowing task. At least one steering wheel 3 is rotatably mounted on the bottom front end of the device body 1 to change its direction of travel when encountering obstacles. The number of steering wheels 3 can be determined according to actual usage requirements. Specifically, there is one steering wheel 3, which can be arranged in the center of the bottom front end of the device body 1, forming an isosceles triangle with the pair of drive wheels 2.

[0043] It should be noted that the aforementioned forward and backward directions refer to the direction of travel of the main body 1 of the device, specifically as follows: Figure 2 Regarding the placement of the lawnmower shown, the direction indicated by the arrow in the figure represents the direction of travel of the main body 1. The upper end of the figure is the bottom rear end of the main body 1, and the lower end of the figure is the bottom front end of the main body 1.

[0044] With this configuration, when the lawnmower encounters obstacles such as tree trunks or branches while traveling, the steering wheel 3 will rotate due to the resistance, thereby driving the main body 1 to change its forward direction and avoid the obstacle. This achieves automatic obstacle avoidance operation of the lawnmower without human intervention, avoiding damage to the blades, eliminating safety hazards, and reducing operating costs. Its structure is simple, easy to operate, and saves time and effort.

[0045] In the embodiments of this utility model, such as Figure 2 As shown, the lawnmower also includes a cutting chamber, cutting blades 4, and multiple grass inlet channels 5. The cutting chamber is located at the bottom of the main body 1, and the cutting blades 4 are rotatably mounted within it. It can be understood that the cutting blades 4 rotate suspended in the air, maintaining a certain distance from the ground, thus neatly cutting the grass and resulting in a smooth and aesthetically pleasing lawn. It should be noted that the distance between the cutting blades 4 and the ground can be determined based on actual usage requirements.

[0046] Each grass inlet channel 5 is distributed at intervals along the circumference of the main body 1 of the device, and the grass inlet channels 5 are arranged to run through the height of the main body 1 of the device, and each grass inlet channel 5 is connected to the cutting chamber. Specifically, as shown in the figure... Figure 2 As shown, the grass inlet channels 5 are located on the outer edge of the main body 1 of the device, and the various grass inlet channels 5 are evenly distributed along the circumference of the main body 1 of the device, which facilitates processing and manufacturing. The number and location of the grass inlet channels 5 can be determined according to actual usage requirements. It should be noted that, as shown in the example... Figure 2 Regarding the placement of the lawnmower shown, the direction perpendicular to the paper in the diagram is the height direction of the main body 1 of the device.

[0047] This setup, through the combined use of multiple grass inlet channels 5 and cutting blades 4, can gather and collect the grass entering the grass inlet channels 5, making it easier for the cutting blades 4 to cut the grass, and improving cutting efficiency and speeding up the operation process.

[0048] Furthermore, in the embodiments of this utility model, such as Figure 2 As shown, the lawnmower also includes multiple protrusions 6, each corresponding to a grass inlet channel 5, and the protrusions 6 are positioned within the grass inlet channel 5. The protrusions 6 prevent obstacles entering the grass inlet channel 5 from contacting the cutting blade 4. With this configuration, when the main body 1 encounters an obstacle, such as a tree branch, the branch slides into the grass inlet channel 5 along with the grass, first encountering the protrusion 6, thus preventing the cutting blade 4 from contacting the branch. Subsequently, during forward movement, the branch slides out of the grass inlet channel 5, ensuring that only grass can enter the cutting chamber. This effectively protects the cutting blade 4, extends the equipment's service life, and reduces maintenance costs.

[0049] As an optional embodiment of this utility model, the number of cutting blades 4 is at least two, and each cutting blade 4 is distributed at intervals along the circumference of the main body 1 of the device. The number can be determined according to actual usage requirements. Specifically, as shown... Figure 2 As shown, there are three sets of cutting blades 4, which are evenly distributed around the circumference of the main body 1 of the device, with their rotation centers located on the same circumference. This arrangement, by setting multiple sets of cutting blades 4, can increase the cutting speed, improve cutting efficiency, and ensure that the cutting operation is carried out efficiently and quickly.

[0050] In specific embodiments of this utility model, such as Figure 2 As shown, the cutting tool 4 includes a rotating shaft and multiple cutting blades 41. Specifically, the rotating shaft is rotatably disposed in the cutting chamber, and the rotating shaft is arranged along the height direction of the main body 1 of the device. Each cutting blade 41 is connected to the rotating shaft, and the cutting blades 41 are distributed at circumferential intervals along the rotating shaft. For example, as shown... Figure 2 As shown, there are three cutting blades 41, evenly distributed around the rotating shaft. The specific number can be determined according to actual design requirements. This arrangement, with the rotating shaft driving multiple cutting blades 41 to rotate, ensures effective cutting of grass, improves weeding efficiency, and guarantees the reliability and efficiency of the cutting operation.

[0051] In an optional embodiment of this utility model, such as Figure 1 As shown, the lawnmower also includes a solar panel 7, which is mounted on the top of the main body 1 of the device. The solar panel 7 is used to provide power to the lawnmower. This configuration allows the device to be powered by solar energy, making it more energy-efficient and environmentally friendly, and reducing operating costs. Of course, in other embodiments, other power supply devices, such as batteries and power interfaces, can also be provided to ensure that the equipment can operate reliably.

[0052] In a specific embodiment of this utility model, the lawnmower also includes a first drive device (not shown in the figure), which drives the cutting blade 4 to rotate, thereby realizing the automatic operation of the lawnmower. Specifically, the first drive device includes a first motor, the output shaft of which is connected to the rotating shaft via a transmission, for example, through gear transmission or a coupling, to realize the rotational cutting of the cutting blade 4. Of course, in other embodiments, a drive motor or similar device can be used, with adaptive adjustments, to drive the cutting blade 4 to rotate. It should be noted that drive motors, gear transmission mechanisms, etc., are all commonly used devices in the art, so their specific structures will not be described in detail here.

[0053] In an optional embodiment of this utility model, the lawnmower further includes a second drive device (not shown in the figure). The second drive device is used to drive a pair of drive wheels 2 to rotate, thereby enabling the lawnmower to move automatically. Specifically, the second drive device includes a second motor, the output shaft of which is connected to the axle of the pair of drive wheels 2, thereby driving the pair of drive wheels 2 to rotate, and thus driving the main body 1 of the device forward continuously. Of course, in other embodiments, a drive motor or the like can also be used, with adaptive adjustments, to drive the drive wheels 2 to rotate. It should be noted that drive motors, drive motors, and related transmission methods are all commonly used devices in the art, so their specific structures will not be described in detail here.

[0054] Furthermore, in this embodiment of the invention, the main body 1 of the device has an internal cavity, and both the first driving device and the second driving device are disposed within the cavity. This provides protection for the driving devices and facilitates overall handling and transfer, making it more convenient and reliable to use.

[0055] In an optional embodiment of this utility model, the steering wheel 3 is configured as a universal wheel, thereby enabling the main body 1 of the device to rotate in any direction, making it more flexible and convenient to use, and effectively ensuring that it can avoid obstacles.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
