Technical Field

[0001] This utility model relates to the field of lawnmower technology, and in particular to a lawnmower that includes a multi-functional engine base. Background Technology

[0002] A lawnmower is a machine used to trim lawns. It trims lawns by rotating blades or other cutting systems to help keep lawns tidy. To improve functionality and applicability, existing lawnmowers have motor bases that can be connected to different attachments or modules to achieve multiple functions. For example, different blades and snowplows can be connected to achieve different functions such as mowing and snow shoveling.

[0003] Traditional lawnmowers are set and adjusted via remote control and control box, allowing the mower to move according to the preset level. Internal obstacle avoidance sensors protect the device along its path. The wheels drive the mower, and the rotating blades cause the blades to spin at high speed, thus trimming the lawn. However, in actual use, it has been found that the blade position and height on existing lawnmowers are fixed and difficult to adjust, limiting the lawn to a uniform height and thus restricting its application. Utility Model Content

[0004] The technical problem this invention aims to solve is that the blade position height on existing lawnmowers is fixed and difficult to adjust, thus limiting the lawn to a uniform height and consequently restricting its application.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a lawnmower including a multi-functional engine base, comprising a lawnmower body, a base plate mounted on the surface of the lawnmower body, wherein the engine body and control box are disposed on the surface of the base plate, two wheels are respectively mounted on both sides of the surface of the lawnmower body, and a drive motor is disposed on one side of the wheels, and a blade disc is mounted on the bottom surface of the base plate by means of an adjustment device, wherein blades are respectively disposed at both ends of the blade disc, and the adjustment device adjusts the position and height of the blade disc and the blades by means of a mounting tube and an adjustment rod.

[0006] The effect achieved by the above components is that when adjusting the height of the blades and cutters on the base plate of the lawnmower body from the ground, the lawnmower body can be adapted to different usage environments by operating the adjustment device on the base plate.

[0007] Preferably, the adjusting device includes a mounting tube, one end of which is fixedly connected to the output assembly of the engine. An adjusting rod is connected to the inner wall of the mounting tube, one end of which is fixedly connected to the cutter head. Support rods are rotatably connected to both sides of the surface of the adjusting rod.

The fixing plate is rotatably disposed with the support rod, and the fixing plate is fixedly connected to the inner wall of the slide rail by bolts.

[0008] The effect achieved by the above components is that, when the lawnmower is in use, the height of the blade from the ground can be adjusted according to actual usage needs, thereby better adapting to different working environments and improving the usage effect and functionality of the lawnmower.

[0009] Preferably, the adjusting device further includes an operating block mounted on the surface of the bolt, wherein the operating block assists in the use of the bolt.

[0010] The effect achieved by the above components is that the operation block makes it easier and faster to rotate the bolt, thereby making it easier to adjust the height of the cutter head.

[0011] Preferably, the adjusting device further includes a shim fitted onto the arc surface of the bolt, wherein the shim enhances the limiting effect of the bolt.

[0012] The effect achieved by the above components is that, by using rubber gaskets, the bolts can fit more closely when passing through the surface of the fixing plate, making it less likely for gaps to form, thereby ensuring the stability of the fixing plate and the support rod.

[0013] Preferably, a spring is installed on one side of the fixing plate, wherein the other end of the spring is fixedly connected to the inner wall of the slide rail.

[0014] The effect achieved by the above components is that, through the setting of the spring, the support rod can form a certain limiting effect under the action of the spring force, which makes it less likely to wobble excessively when adjusting the height of the cutter head blade from the ground, thus improving the convenience of using the adjustment device.

[0015] Preferably, sliders are fixedly connected to both sides of the surface of the adjusting rod, wherein the sliders are slidably connected to the grooves on the surface of the mounting tube.

[0016] The effect achieved by the above components is that, through the sliding arrangement of the slider and the groove, the adjusting rod and the mounting tube are more stable and in place when the combined length is adjusted by sliding, and are less prone to wobbling.

[0017] Preferably, the surface of the slide rail is fixedly connected to a mounting shaft, and several rollers are rotatably connected to the arc surfaces of the two mounting shafts respectively.

[0018] The effect achieved by the above components is that, by setting up the mounting shaft and rollers, the rollers on the mounting shaft can rotate and roll on the surface of the base plate when the slide rail rotates, thereby making the slide rail more stable and less prone to shaking.

[0019] The beneficial effects of this utility model are:

[0030] Figure 1 and Figure 2 The lawnmower shown includes a multi-functional engine base, comprising a lawnmower body 1, a base plate 3 mounted on the surface of the lawnmower body 1, an engine body 4 and a control box 5 mounted on the surface of the base plate 3, two wheels 9 mounted on each side of the surface of the lawnmower body 1, and a drive motor 6 located on one side of the wheel 9. A blade disc 7 is mounted on the bottom surface of the base plate 3 via an adjustment device 2, with blades 8 mounted at both ends of the blade disc 7. The adjustment device 2 adjusts the position and height of the blade disc 7 and the blades 8 via a mounting tube 21 and an adjustment rod 22. When adjusting the height of the blade disc 7 and the blades 8 on the base plate 3 of the lawnmower body 1 from the ground, the adjustment device 2 on the base plate 3 can be operated to adapt the lawnmower body 1 to different usage environments.

[0031] Figures 1-4 The adjustment device 2 shown includes a mounting tube 21, one end of which is fixedly connected to the output assembly of the engine. An adjustment rod 22 is connected to the inner wall of the mounting tube 21, one end of which is fixedly connected to the blade disc 7. Support rods 23 are rotatably connected to both sides of the surface of the adjustment rod 22. A disc 25 is mounted on the base surface, with an arc-shaped plate 26 slidably connected to the inner wall of the disc 25. A slide rail 24 is fixedly connected to the surface of the arc-shaped plate 26, and a fixing plate 27 is slidably connected to the inner wall of the slide rail 24. The fixing plate 27 is rotatably mounted to the support rods 23, and the fixing plate 27 is fixedly connected to the inner wall of the slide rail 24 by bolts 28. When adjusting the height of the blade disc 7 and blades 8 on the base disc 3 of the lawnmower body 1 from the ground... When the position is adjusted, the adjusting rod 22 fixedly connected to the cutter head 7 can be slid, causing the adjusting rod 22 to slide on the inner wall of the mounting tube 21. This causes the support rods 23 rotatably mounted on both sides of the adjusting rod 22 to rotate. At this time, the fixing plate 27 rotatably connected to one end of the support rod 23 will slide on the inner wall of the slide rail 24 until the position of the cutter head 7 is adjusted to the appropriate height. Then, the bolt 28 is inserted through the surface of the fixing plate 27, so that the bolt 28 is threadedly connected to the inner wall of the slide rail 24, thereby fixing the position of the adjusting rod 22 and the cutter head 7. When the lawnmower body 1 is in use, the height of the cutter head 7 from the ground can be adjusted according to the actual usage requirements, so as to better adapt to different working environments and improve the usage effect and functionality of the lawnmower body 1.

[0032] Figures 1-5 The adjustment device 2 shown also includes an operating block 214 installed on the surface of the bolt 28. The operating block 214 assists in the use of the bolt 28. The setting of the operating block 214 makes it easier and faster to rotate the bolt 28, thereby making it easier to adjust the height of the cutter head 7. The adjustment device 2 also includes a shim 215 sleeved on the arc surface of the bolt 28. The shim 215 enhances the limiting effect of the bolt 28. The setting of the rubber shim 215 makes the bolt 28 fit more closely when passing through the surface of the fixing plate 27, and it is not easy for gaps to be generated, thereby ensuring the stability of the position of the fixing plate 27 and the support rod 23.

[0033] Figures 1-5 A spring 29 is installed on one side of the fixed plate 27 shown, and the other end of the spring 29 is fixedly connected to the inner wall of the slide rail 24. The spring 29 allows the support rod 23 to form a certain limiting effect under the elastic force of the spring 29, making it less likely to wobble excessively when adjusting the height of the blade 8 of the cutter head 7 from the ground, thus improving the ease of use of the adjustment device 2. Slider 213 is fixedly connected to both sides of the surface of the adjustment rod 22, and the slider 213 is slidably connected to the groove 212 on the surface of the mounting tube 21. The sliding arrangement of the slider 213 and the groove 212 makes the adjustment rod 22 and the mounting tube 21 more stable and limited when sliding to adjust the combined length, and less likely to wobble.

[0034] Figure 1 and Figure 4 The slide rail 24 shown is fixedly connected to a mounting shaft 210. Several rollers 211 are rotatably connected to the arc surfaces of the two mounting shafts 210. By setting the mounting shafts 210 and rollers 211, when the slide rail 24 rotates, the rollers 211 on the mounting shafts 210 can rotate and roll on the surface of the base plate 3, thereby making the slide rail 24 more stable and less prone to shaking.

[0035] Working Principle: When adjusting the height of the blade 7 and blades 8 on the base plate 3 of the lawnmower body 1, the adjusting rod 22 fixedly connected to the blade 7 can be slid, causing the adjusting rod 22 to slide against the inner wall of the mounting tube 21. This causes the support rods 23 rotatably mounted on both sides of the adjusting rod 22 to rotate. At this time, the fixing plate 27 rotatably connected to one end of the support rod 23 will slide against the inner wall of the slide rail 24 until the position of the blade 7 is adjusted to the appropriate operating height. Then, the bolt 28 is inserted through the surface of the fixing plate 27, making the bolt 28 threadedly connected to the inner wall of the slide rail 24, thereby fixing the position of the adjusting rod 22 and the blade 7. When the lawnmower body 1 is in use, the operator starts the lawnmower body 1 through the remote control (model Flysky FS-i6X) or the control box 5. Then, the internal GPS (model RTK) and obstacle avoidance sensor (model Ultrasonic Module) are activated. The HC-SR04 sets and plans the running trajectory. At this time, the generator (model Husqvarna) inside the lawnmower body 1 will supply power to the system. Then, the engine body 4 (model Honda GX160) will drive the blade 7 on one side of the adjustment device 2 to rotate, and the drive motor 6 will output power to the wheels 9 to make them run, driving the lawnmower body 1 to travel on the grass. At this time, when the lawnmower body 1 is in use, the height of the blade 7 off the ground can be adjusted according to the actual use needs, so as to better adapt to different working environments and improve the use effect and functionality of the lawnmower body 1.

[0036] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
