DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0023] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0024] The embodiment of the present invention provides a garden lawn intelligent mowing device, such as Figure 1-Figure 7 As shown, it includes: The main shell 900 and the main frame, the main frame serves as the installation base for other components including the main shell 900, and the other components can be directly or indirectly installed on the main frame and form a relative whole after installation; the main shell 900 is covered on the main frame, and the main shell 900 can surround a space relatively isolated from the external environment. Most of the other components are located in the space to protect the components inside the main shell 900 and prevent mechanical parts from causing harm to the user.

[0025] The cutting assembly 100 is used to cut grass plants and complete the lawn mowing operation. The cutting assembly 100 rotates around a first axis. Usually, the cutting assembly 100 is driven by a motor or an engine, and the first axis is the axis of the motor or engine output shaft 410. The cutting assembly 100 can be a rigid metal cutting blade, or a flexible cutting rope, cutting belt 120, etc. It can be understood that other common cutting mechanisms can be used in the present invention.

[0026] The guide assembly 200 is used to raise the fallen grass plants. In the lawn, the grass plants may fall down due to external forces such as being stepped on by people. The fallen grass plants may not be cut by the cutting assembly 100 due to their low height, and then they will straighten up again due to their own growth or other external forces, so that the flatness of the mowed lawn will decrease. The above situation can be avoided by raising the fallen grass plants with the guide assembly 200. It can be understood that for normal grass plants, the guide assembly 200 has no or limited guiding effect; the guide assembly 200 can make the shapes of all the guided grass plants tend to be consistent, and is not limited to guiding the grass plants into a straight state.

[0027] The smoothing component 300 is used to adjust the posture of the grass after it is lifted up, so that the top of the grass rotates in the opposite direction of the rotation direction of the cutting component 100 compared to the bottom of the grass. Taking the rigid cutting blade as an example, when the cutting component 100 cuts the grass, the cutting blade rotates and contacts the grass. At this time, the effect of the cutting blade on the grass is mainly manifested in two forms: one is that the cutting blade along the contact point separates the grass from top to bottom, and the other is that the cutting blade drives the grass to move along the direction of rotation of the cutting blade. If the grass is in an upright state, the grass will fall in the direction of rotation of the cutting blade under the driving action of the cutting blade, thereby making it impossible for the cutting blade to cut in a direction perpendicular to the grass, or after the grass falls, the cutting blade can only cut part of the grass, resulting in uneven cutting effect of the cutting blade on the grass, and thus making the lawn after mowing poorly flat. The posture of the grass is adjusted by the smoothing component 300 so that the top of the grass rotates in the opposite direction of the rotation direction of the cutting component 100 compared to the bottom of the grass, that is, the grass falls toward the direction of the cutting component 100; at this time, when the cutting component 100 cuts the grass, even if the grass will be driven by the cutting component 100 and fall in the direction of rotation of the cutting component 100, the cutting effect of the cutting component 100 on the grass can be guaranteed.

[0028] The drive assembly 400, as the power source in the garden lawn intelligent trimming device, provides power for the movement of other components, including but not limited to the rotation of the cutting component 100, the movement of the smoothing component 300, etc. It is understandable that the drive assembly 400 can be a common drive form, such as an electric motor, an internal combustion engine, etc. The power source in the drive assembly 400 can be centralized, and the power is transmitted to other components through a transmission structure; the power source can also be decentralized, and multiple decentralized power sources drive the movements of various components respectively.

[0029] It can be understood that in order to ensure the final cutting effect, the grass plants should first pass through the guide component 200. After being guided by the guide component 200, the grass plants are in a relatively upright state; then the grass plants pass through the smoothing component 300, and the smoothing component 300 makes the grass plants evenly tilted, so that the grass plants all tilt in the direction of the cutting component 100; finally, the grass plants are cut by the cutting component 100 and the lawn trimming operation is completed.

[0030] Generally, along the direction of travel of the garden lawn intelligent trimming device, the front end of the guide component 200 is located in front of the smoothing component 300, and the smoothing component 300 is located in front of the cutting component 100. The positional relationship between the guide component 200, the smoothing component 300 and the cutting component 100 can be various, such as the guide component 200 can always guide the grass plants during the entire trimming process so that the roots of the grass plants remain relatively upright. However, the positional relationship between the guide component 200, the smoothing component 300 and the cutting component 100 should be such that the grass plants are first lifted up, then tilted in a directional manner, and finally cut.

[0031] Therefore, the garden lawn intelligent trimming device provided by the embodiment of the present invention guides and controls the shape of the grass plants in advance, so that when the grass plants contact and are cut by the cutting component 100, the grass plants can contact the cutting component 100 in a posture tilted toward the cutting component 100, thereby improving the cutting effect of the cutting component 100 and further improving the flatness of the lawn after trimming by the garden lawn intelligent trimming device.

[0032] In one embodiment, the guide assembly 200 includes a plurality of mutually parallel guide bars 210, and a grass-supporting gap is formed between any two adjacent guide bars 210. Since the growth direction and the falling direction of the grass plants are random, when the garden lawn intelligent trimming device is moving, the guide bars 210 will straighten the grass plants that grow or fall along the direction at an angle to the setting direction of the guide bars 210. In this process, due to the mutual influence between the grass plants, the grass plants that grow or fall in the direction in which the guide bars 210 are set will be straightened, thereby straightening most of the grass plants, which is convenient for subsequent trimming operations.

[0033] Furthermore, the guide bar 210 includes an inclined section 212 and a straight section 214. Along the direction of travel of the garden lawn intelligent mowing device, the inclined section 212 is located in front of the straight section 214, and the inclined section 212 is inclined toward the ground. By providing the inclined section 212, grass plants with a larger tilt angle and closer to the ground can be "scooped up" and straightened.

[0034] In one embodiment, the smoothing assembly 300 includes an arc frame 310, a conveyor belt 320 and a smoothing roller 330. The arc frame 310 is arranged above the guide assembly 200. The cross-sectional shape of the arc frame 310 along the horizontal direction is a circular ring. The conveyor belt 320 is rotatably arranged on the arc frame 310. The smoothing roller 330 is arranged on the conveyor belt 320. When the conveyor belt 320 rotates around the arc frame 310, it can drive the smoothing roller 330 to move.

[0035] The smoothing roller 330 is located at a certain distance above the guide assembly 200. After the grass is straightened by the guide assembly 200, the top of the grass protrudes from the guide assembly 200. When the smoothing roller 330 rotates around the arc frame 310, the smoothing roller 330 contacts the top of the grass and drives the grass to fall along the moving direction of the smoothing roller 330. Since the smoothing roller 330 rotates around the arc frame 310, the moving track of the smoothing roller 330 is an arc, and the arc corresponds to the rotation direction of the cutting assembly 100, so that the falling direction of the grass corresponds to the rotation direction of the cutting assembly 100, so that the grass falls toward the cutting assembly 100 when it contacts the cutting assembly 100.

[0036] In one embodiment, the smoothing assembly 300 further includes a connecting frame, which is fixedly connected to the conveyor belt 320 , and the smoothing roller 330 is rotatably disposed on the connecting frame.

[0037] It can be understood that the part of the smoothing component 300 that comes into contact with the grass can be a smoothing roller 330, or a smoothing block, a smoothing plate and other structures. These structures can be fixedly connected to the conveyor belt 320, or movably connected to the conveyor belt 320, but these structures should be able to force the grass to fall in a preset direction.

[0038] In one embodiment, the cutting assembly 100 includes a cutting frame 110 and a cutting belt 120. The cutting frame 110 can rotate around a first axis, and the cutting belt 120 can be rotatably arranged around the cutting frame 110. For ease of description, in this embodiment and the following embodiments, the rotation of the cutting frame 110 around the first axis is referred to as revolution, and the rotation of the cutting belt 120 around the cutting frame 110 is referred to as rotation. The cutting belt 120 has two cutting edge lines. When the cutting frame 110 revolves, on the one hand, it drives the cutting belt 120 to revolve and contact with the grass plants and cut them. On the other hand, the revolution of the cutting frame 110 can make the two cutting edge lines on the cutting belt 120 cut the grass plants alternately; the rotation of the cutting belt 120 can make different parts of the cutting edge lines contact with the grass plants more evenly and cut the grass plants. Through the revolution of the cutting frame 110 and the rotation of the cutting belt 120, the two cutting edge lines of the cutting belt 120 are evenly involved in cutting, and the service life of the cutting belt 120 will not be short due to excessive use of a local cutting edge line.

[0039] In particular, for the embodiment provided with the arc frame 310, the revolution of the cutting belt 120 can be adapted to the falling direction of the grass plants.

[0040] In one embodiment, the driving assembly 400 includes an output shaft 410 and a reduction mechanism. The output shaft 410 drives the cutting frame 110 to rotate. The output shaft 410 drives the cutting belt 120 to rotate through the reduction mechanism. The rotation speed of the cutting frame 110 is lower than the rotation speed of the cutting belt 120.

[0041] Specifically, the speed reduction mechanism includes a first transmission gear 421, a double gear 423, a second transmission gear 422, a worm 424 and a turbine 425. The output shaft 410 drives the first transmission gear 421 to rotate. The first transmission gear 421 and the small gear in the double gear 423 are meshed for transmission. The large gear in the double gear 423 and the second transmission gear 422 are meshed for transmission. The second transmission gear 422 and the worm 424 are fixedly connected as one body. The second transmission gear 422 is sleeved on the output shaft 410 and can rotate relative to the output shaft 410. The worm 424 is meshed with the turbine 425. A contact surface is provided on the outer peripheral wall of the turbine 425. The contact surface contacts the cutting belt 120 and drives the cutting belt 120 to rotate. The cutting frame 110 is fixedly connected to the output shaft 410. Therefore, the revolution of the cutting frame 110 and the rotation of the cutting belt 120 are driven simultaneously by the single power source of the output shaft 410, and the rotation speed of the cutting belt 120 is relatively fast. It is understandable that other common speed reduction mechanisms can also be applied to the present invention, such as speed reducers, transfer cases, etc. Similarly, the cutting frame 110 and the cutting belt 120 can also be driven by multiple power sources, such as by providing two drive motors to drive them separately.

[0042] In one embodiment, the garden lawn intelligent trimming device also includes a heating component 500. Due to temperature differences, weather and other reasons, the grass may be relatively moist as a whole, and the high flexibility of the grass may make trimming more difficult; and the surface of the cutting component 100 may be adhered to the juice of the grass stem, thereby further increasing the cutting difficulty of the cutter. The heating component 500 is provided to heat and dry the grass before the grass comes into contact with the cutting component 100, so that the grass is relatively dry to improve the cutting effect.

[0043] Specifically, the heating component 500 includes a heating coil disposed on the smoothing component 300, and a heating medium flows in the heating coil, and the heating medium can exchange heat with the driving component 400. If the driving component 400 includes a diesel engine, the residual heat of the engine during operation is transferred to the smoothing component 300 through the flowing medium in the heating coil, so that the temperature of the entire smoothing component 300 is relatively high, and the smoothing component 300 can heat and dry the grass when it comes into contact with the grass. It is understandable that other common heating and drying structures can be applied to the present invention, such as electric heating wires, hot air blowers, etc.

[0044] In one embodiment, the garden lawn intelligent trimming device further includes a collection component, which is used to collect debris generated when the cutting component 100 cuts the grass. The collection component includes a collection fan and a collection air duct, and the inlet of the collection air duct is arranged near the cutting component 100. The cutting component 100 moves the debris after the grass is cut along the collection air duct under the suction of the collection fan. A collection bag or other structure can be arranged at the outlet of the collection air duct to collect the debris; or the outlet of the collection air duct directly leads to the external environment, and the debris is directly discharged to the lawn that has been cut.

[0045] In one embodiment, the driving assembly 400 can also be used to drive the garden lawn intelligent mowing device to move forward.

[0046] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
