Description

Technical Field

[0001] This utility model relates to the field of lawnmower technology, specifically a ride-on lawnmower. Background Technology

[0002] Golf courses, as high-standard sports venues, have stringent requirements for the flatness and precision of the turf. Lawn mowers are the core equipment for ensuring the quality of the golf course turf during maintenance. Compared to ordinary courses, golf course turf covers a vast area and includes different functional areas such as greens, fairways, and rough, placing higher demands on the efficiency, maneuverability, and adaptability of lawn mowers. Lawn mowers are becoming increasingly widely used, with push mowers being the most common. However, push mowers have poor maneuverability and require significant physical exertion from the operator, hence the gradual development of ride-on mowers.

[0003] Most existing ride-on lawnmowers are battery-powered, requiring a person to sit on the vehicle and drive it. The three-roller blades then cut the lawn. For example, Chinese utility model patent CN211793024U discloses a ride-on lawnmower.

[0004] However, the seats of existing ride-on lawnmowers are difficult to adjust. If the seat is too far away, the operator must lean forward to reach the steering wheel, causing continuous tension in the back, shoulder, and neck muscles. If it is too close, the knees will hit the bottom of the steering wheel, and the legs will be cramped, which is also uncomfortable. In addition, the seat has poor shock absorption, which greatly reduces driving comfort. Summary of the Invention

[0005] The purpose of this invention is to provide a ride-on lawnmower that solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ride-on lawnmower, comprising a body and an adjustable base mounted on top of the body. A shock absorber is mounted on top of the adjustable base, and a seat is mounted on top of the shock absorber. A safety belt is mounted on the seat. A rear wheel assembly, a three-roller blade assembly, and a front wheel assembly are mounted below the body. The three-roller blade assembly is located at the front end of the body. The adjustable base is used to adjust the seat position, the shock absorber is used for cushioning and damping the seat, and the safety belt is used to secure the driver to the seat. The adjustable base allows for seat position adjustment to meet the needs of different drivers. The shock absorber provides cushioning and damping during driving, improving comfort. The rear wheel assembly and front wheel assembly enable the driving of the lawnmower, and the three-roller blade assembly performs mowing operations on the lawn.

[0007] In a preferred embodiment of this invention, the adjustable base includes a slide rail, a lead screw, a slider, and an adjusting plate. The slide rail is fixed to the machine body. The lead screw is rotatably connected inside the slide rail and parallel to it. The slider is threadedly connected to the lead screw and is in contact with the inner wall of the slide rail via a sliding connection. The adjusting plate is fixed to the slider. By rotating the lead screw, the lead screw adjusts the slider, which in turn moves the adjusting plate. The adjusting plate then moves the seat via a shock absorber, thereby adjusting the seat position.

[0008] In a preferred embodiment of this invention, one end of the lead screw passes through a slide rail and is connected to a knob. The knob facilitates the rotation of the lead screw.

[0009] In a preferred embodiment of this invention, the shock absorber includes a damper and a buffer spring. The buffer spring is sleeved on the outside of the damper, and both ends of the buffer spring and the damper are fixed to the adjusting plate and the seat, respectively. The damper suppresses rebound, and the buffer spring absorbs kinetic energy, thereby achieving the effect of cushioning and shock absorption.

[0010] In a preferred embodiment of this invention, the protective belt includes a seat belt, a buckle, and a fastener. The seat belt is connected to one side of the seat, the fastener is connected to the other side of the seat, and the buckle is fixed to the end of the seat belt. The buckle and the fastener cooperate with each other. After the driver sits in the seat, the seat belt is fastened around the driver's waist, and then the buckle is engaged with the fastener, thus improving the driver's safety.

[0011] As a preferred embodiment of this invention, a roof support beam is provided above the seat. This roof support beam is used to install a sunshade, providing protection for the driver's seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention, through the combination of an adjustable base and a knob, allows for easy adjustment of the seat position. Whether the driver is of different height and build, or adjusts their posture according to their driving habits, a comfortable seat position can be found, significantly improving the lawnmower's adaptability to different users and reducing driver fatigue caused by uncomfortable seat positions. The damper and buffer spring of the shock absorber work together to effectively absorb and weaken the vibrations generated during the lawnmower's operation, reducing the transmission of vibrations to the driver's body and avoiding discomfort such as back pain and other discomforts caused by vibrations during long-term driving, thus significantly improving driving comfort.

[0017] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a ride-on lawnmower, including a body 1 and an adjustable base 2 disposed on top of the body 1. A shock absorber 3 is disposed on top of the adjustable base 2, a seat 4 is disposed on top of the shock absorber 3, and a protective belt 5 is disposed on the seat 4. A rear wheel assembly 6, a triple-roller device 8 and a front wheel assembly 7 are disposed below the body 1. The triple-roller device 8 is disposed at the front end of the body 1. The adjustable base 2 is used to adjust the position of the seat 4, the shock absorber 3 is used for cushioning and damping the seat 4, and the protective belt 5 is used to tie the driver to the seat 4.

[0019] The adjustable base 2 allows the seat 4 to be positioned to meet the needs of different drivers. The shock absorber 3 provides cushioning and vibration reduction during driving, improving comfort. The rear wheel assembly 6 and the front wheel assembly 7 enable the lawnmower to be driven. The triple-roller blade device 8 performs grass mowing operations on the lawn after the machine passes over.

[0020] Each cutter in the triple-roller device 8 is raised and lowered via a lifting system, which can adapt to slopes or terrain undulations of up to 42°. Furthermore, the cutter heads of the triple-roller device 8 are replaceable, allowing the use of multiple cutter head models.

[0021] In this embodiment, the connection method between each cutter head and the hob shaft of the three-section hob device 8 with the positioning cutter head connection structure is "shaft, sleeve, fastener locking".

[0022] The main body of the cutter head is a ring or disc-shaped structure, with a "sleeve" in the center that matches the hob shaft. The inner wall of the sleeve has a positioning keyway (which works with the positioning key of the hob shaft to ensure that the cutter head rotates without deviation and to ensure cutting accuracy).

[0023] Two to four fastening bolts (or lock nuts) are provided on the outside of the bushing, evenly distributed along the circumference of the bushing, to fix the cutter head on the hobbing shaft (to prevent the cutter head from loosening during high-speed rotation).

[0024] To disassemble the fastening parts, use a wrench of the appropriate size (such as an Allen wrench or an open-end wrench, depending on the bolt type). Loosen the fastening bolts / nuts on the cutter head bushing clockwise. Place the bolts, washers, and other small parts into a special storage box (to avoid loss or confusion, as the original parts need to be returned to their original positions for subsequent installation).

[0025] After removing the old cutter head, hold the rigid edges (non-cutting surfaces of the blade) on both sides of the cutter head with both hands and gently pull it outward along the axis of the hob shaft to disengage the bushing of the cutter head from the hob shaft. (If the cutter head and the shaft fit tightly, you can gently tap the rigid part on the side of the cutter head to help separate it with vibration, but avoid tapping the blade to prevent the blade from deforming and affecting the flatness of the cut.)

[0026] When installing a new cutter head, check whether the keyway of the new cutter head's bushing matches the positioning key of the cutter shaft, and whether there are curled edges or notches on the blade edge (if there are defects, a new cutter head should be replaced to avoid affecting the accuracy of lawn mowing).

[0027] Align the positioning structure and install the cutter head. Align the keyway of the new cutter head's bushing with the positioning key of the hob shaft, and slowly push it in axially until the cutter head fits against the stepped surface of the hob shaft (after fitting, the cutter head should not have any axial looseness). Crucially: Ensure the keyway and positioning key are perfectly aligned. Forcing installation will deform the keyway, causing "eccentricity" during subsequent cutter head rotation, resulting in uneven lawn cutting.

[0028] Tighten and lock, control the torque and put the removed bolts and washers back into the screw holes of the cutter head bushing in their original positions. First, tighten them by hand until they fit, and then use a wrench to tighten them in a "diagonal sequence" in stages (e.g., for 4 bolts, tighten diagonal 1 and 3 first, then diagonal 2 and 4) to avoid uneven force on the cutter head causing it to shift.

[0029] Furthermore, the triple-roller device 8 uses a floating blade. When the lawnmower is moving, the floating blade conforms to the undulations of the ground under the elastic action of the compressed spring, and the blade always maintains stable contact with the lawn, avoiding missed or over-cutting due to ground depressions / protrusions. It is especially suitable for "hilly" lawn areas around the greens of golf courses, ensuring that the height error of the lawn after cutting is ≤2mm.

[0030] The triple hobbing cutter assembly 8 supports quick replacement of 11-flute and 14-flute hobbing cutter assemblies with existing hobbing cutter assemblies, all three having consistent structural compatibility. The disassembly process is identical to that of the existing cutter heads, requiring no additional modifications to the frame or transmission structure of the triple hobbing cutter assembly 8.

[0031] Before mowing, the rotating brush roller rotates synchronously with the front wheel to sweep away debris such as fallen leaves, pebbles, and broken branches from the lawn surface to both sides (the sweeping width is consistent with the length of the brush roller), preventing debris from entering the triple roller device 8 and causing the blades to break. After mowing, the height of the brush roller can be adjusted to 20-30mm to comb the cut grass blades, making the lawn surface smoother and reducing the accumulation of grass clippings.

[0032] The device is also compatible with a grass combing attachment. When there is a layer of dead grass on the lawn, install the grass combing attachment and adjust the depth of the combing teeth into the soil to 10-20mm. During the mower's operation, the combing teeth insert into the surface of the lawn, combing out the withered grass stems and roots from the soil and expelling them backward as the mower moves, improving the lawn's aeration and promoting the growth of new grass. It is especially suitable for the quarterly "dead grass cleaning and maintenance" of golf course fairways.

[0033] The drive of the rear wheel assembly 6, the front wheel assembly 7 controlled by the steering system in the driver's seat, and the use of the three-section roller cutter device 8 and its lifting system are all existing mature technologies, so they will not be described in detail here.

[0034] Furthermore, the adjustable base 2 includes a slide rail 201, a lead screw 202, a slider 203, and an adjusting plate 204. The slide rail 201 is fixed to the body 1. The lead screw 202 is rotatably connected inside the slide rail 201 and parallel to the slide rail 201. The slider 203 is threadedly connected to the lead screw 202 and is in contact with the inner wall of the slide rail 201 and is slidably connected. The adjusting plate 204 is fixed to the slider 203. By rotating the lead screw 202, the lead screw 202 adjusts the slider 203 to move, which in turn moves the adjusting plate 204. The adjusting plate 204 then moves the seat 4 via the shock absorber 3, thereby adjusting the position of the seat 4.

[0035] Furthermore, one end of the lead screw 202 passes through the slide rail 201 and is connected to a knob 2021. The knob 2021 is mainly used to facilitate the rotation of the lead screw 202.

[0036] Furthermore, the shock absorber 3 includes a damper 301 and a buffer spring 302. The buffer spring 302 is sleeved on the outside of the damper 301, and the two ends of the buffer spring 302 and the damper 301 are respectively fixed to the adjusting plate 204 and the seat 4. The damper 301 suppresses rebound, and the buffer spring 302 absorbs kinetic energy, thereby achieving the effect of buffering and shock absorption.

[0037] Furthermore, the protective belt 5 includes a seat belt 501, a buckle 502, and a fastener 503. The seat belt 501 is connected to one side of the seat 4, the fastener 503 is connected to the other side of the seat 4, and the buckle 502 is fixed to the end of the seat belt 501. The buckle 502 and the fastener 503 cooperate with each other. After the driver sits in the seat 4, the seat belt 501 is fastened around the driver's waist, and then the buckle 502 is engaged with the fastener 503, improving the driver's safety.

[0038] Furthermore, a canopy support beam 9 is provided above the seat 1. The canopy support beam 9 is used to install a sunshade, which provides protection for the driver's seat.

[0039] In summary, when the position of seat 4 needs to be adjusted, the knob 2021 at the end of the lead screw 202 is rotated. During the rotation of the lead screw 202, the slider 203 is driven to slide along the slide rail 201 via threaded transmission. The slider 203 further drives the adjusting plate 204, the shock absorber 3, and the seat 4 to move synchronously, ultimately achieving precise adjustment of the seat 4 position. When the lawnmower encounters bumpy roads during operation, the resulting vibrations are transmitted to the shock absorber 3. The buffer spring 302 first absorbs the kinetic energy generated by the vibration through its own deformation, initially weakening the vibration. At the same time, the damper 301 suppresses the rebound movement of the buffer spring 302, avoiding secondary vibrations caused by repeated spring extension and contraction. This dual action achieves cushioning and vibration reduction of the seat 4, reducing the impact of vibration on the driver. After the driver sits down, he wraps the seat belt 501 around his waist and then inserts the buckle 502 at the end of the seat belt 501 into the buckle 503 on the other side of the seat 4, so that the buckle 503 and the buckle 502 are tightly engaged, fixing the driver on the seat 4 and preventing the driver's body from shifting during the operation of the lawnmower or when it is bumpy, thus ensuring driving safety.

[0040] It is worth noting that the entire device is controlled by a master control button. Since the device matched with the control button is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
