Description

Technical Field

[0001] This utility model relates to the field of lawnmower technology, specifically to a lawnmower that includes a winding device. Background Technology

[0002] Lawn mowers play a vital role in garden maintenance and lawn management. These machines not only efficiently trim lawns but also ensure they remain neat and aesthetically pleasing. Gardeners and lawn managers rely on lawn mowers to perform daily maintenance tasks, keeping parks, golf courses, sports fields, and other green spaces in excellent condition. The design and functionality of lawn mowers are constantly evolving, enabling them to adapt to various terrains and grass species, thus playing an even greater role in garden maintenance and lawn management.

[0003] Traditional lawnmowers often suffer from inconvenient cable or cutting cord storage, easily becoming tangled and knotted. This not only affects work efficiency but can also damage the cable or cutting cord. Furthermore, the cutting section and cord reel mechanism of traditional lawnmowers are typically complex in structure, making operation less convenient and increasing user difficulty and maintenance costs. In addition, traditional lawnmowers lack precise control over the cutting cord length during mowing, potentially leading to poor mowing results or unnecessary environmental damage. Moreover, the cord reel mechanism of traditional lawnmowers lacks stability during winding, easily resulting in jamming and uneven cord winding. Utility Model Content

[0004] The purpose of this invention is to provide a lawnmower with a winding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a lawnmower including a winding device, comprising an L-shaped connecting rod, a rotating mowing section, and a mower winding section. A handle is fixedly installed at one end of the L-shaped connecting rod, and a mowing button and a winding button are respectively provided on the handle. The rotating mowing section is located at one end of the L-shaped connecting rod; the mower winding section is located at the bottom of the rotating mowing section.

[0006] Preferably, the rotating mowing unit specifically includes: a fixed outer shell, fixedly installed at one end of the L-shaped connecting rod; the fixed outer shell has an opening, and a rotating motor is fixedly installed inside the fixed outer shell. The output end of the rotating motor extends to the outside of the fixed outer shell through the opening. The rotating motor, fixedly installed inside the fixed outer shell, provides a stable power source for the entire mowing machine winding device. The fixed outer shell can protect the rotating motor from the influence of the external environment, such as dust, moisture, and impact, thus extending the service life of the motor.

[0007] Preferably, the output end of the rotating motor is fixedly connected to a protective top shell, and a conductor coil is fixedly installed on the bottom outer wall of the protective top shell. The conductor coil has a wire hole, and the bottom outer wall of the conductor coil is fixedly installed with a protective bottom shell.

[0008] Preferably, the lawnmower take-up unit specifically includes: a rotating positioning sleeve, fixedly installed on the inner wall of the protective bottom shell; a motor fixing bracket, fixedly installed on the inner wall of the protective bottom shell; a positioning sleeve, fixedly installed on the inner wall of the protective bottom shell; a guide block, fixedly installed on the inner wall of the protective bottom shell; and a take-up sleeve, fixedly installed on the inner wall of the wire hole.

[0009] Preferably, a rotary motor is fixedly installed on the inner wall of the motor mounting bracket. A rotating rod is fixedly connected to the output end of the rotary motor, and the other end of the rotating rod is rotatably connected to the inner wall of the protective base. The rotating rod is movably installed inside the rotating positioning sleeve, and a drive gear is fixedly sleeved on the outer wall of the rotating rod. A rotating shaft is rotatably connected inside the positioning sleeve, and a rotary motor is installed therein. The rotary motor provides a powerful power source for the winding process, greatly improving the speed and efficiency of winding compared to traditional manual winding methods, saving time and manpower. After mowing is completed, the user only needs to press the winding button, and the rotary motor quickly starts, driving the winding reel to rotate rapidly through a series of transmission components, neatly retracting the nylon cut wire. This ensures that the winding force is uniform and stable, preventing problems such as uneven cable winding and knots caused by uneven force during manual winding. The rotary motor operates at a constant speed and torque, allowing the nylon cut wire to be wound orderly on the winding reel, providing convenience for the next use.

[0010] Preferably, a rotating base plate is fixedly installed on the top of the rotating shaft, a driven gear is sleeved on the outer wall of the rotating shaft, an mounting sleeve is fixedly installed on the top of the driven gear, the driven gear is fixedly sleeved on the outer wall of the rotating shaft through the mounting sleeve, and a take-up reel is fixedly installed on the top of the rotating base plate.

[0011] Preferably, the inside of the take-up reel is provided with a nylon cutting wire, the upper part of the guide block is provided with a rectangular opening, the inner walls of the rectangular opening are fixedly connected with a movable shaft, the outer wall of the movable shaft is fitted with a guide pulley, the outer wall of the take-up sleeve is fixedly installed with a nylon cutting wire and a fixed sleeve, and the top of the fixed sleeve is provided with a threaded sleeve.

[0012] Preferably, the threaded sleeve has a threaded rod internally threadedly connected to it. One end of the threaded rod is fixedly fitted with a textured cap, and the other end extends through the threaded sleeve into the interior of the fixed sleeve. The other end of the threaded rod is rotatably connected to a limiting block. Fixed rubber strips are equidistantly fixed to the bottom outer wall of the limiting block. The threaded rod, in conjunction with the threaded sleeve and the fixed sleeve, securely fixes the nylon cut wire. When the nylon cut wire passes through the fixed sleeve, rotating the threaded rod pushes the limiting block downwards. The fixed rubber strips at the bottom of the limiting block make close contact with the nylon cut wire, increasing friction and effectively preventing the cable from loosening during operation.

[0013] This utility model provides a lawnmower including a winding device. It has the following advantages:

[0014] (1) This utility model can provide sufficient power by rotating the motor to ensure that the nylon cutting rope rotates at high speed for mowing. This powerful power output greatly improves the mowing efficiency and can quickly handle large areas of grass. The design of the protective top shell and the protective bottom shell provides good protection for the internal mowing components and prevents impact and damage from external objects. The rotating mowing part is connected to the handle through the L connecting rod, so the operator can easily hold the handle to perform mowing operations. The mowing button and the rewind button on the handle allow the operator to easily control the start, stop and rewind of the mower, improving the convenience and efficiency of operation.

[0015] (2) The present invention provides stable power through the rotating motor in the lawnmower take-up section. The rotation speed and direction of the take-up reel are controlled by the cooperation of the active gear and the driven gear. This allows the nylon cut wire to be quickly and neatly retracted after use. The design of the take-up reel can accommodate a certain length of nylon cut wire to meet the needs of different mowing areas. During the take-up process, the take-up reel can tightly wind the wire, reduce the space occupied, and facilitate storage and carrying. The combination of the fixing sleeve, the threaded sleeve and the threaded rod can effectively fix the nylon cut wire. When it is necessary to adjust the length of the nylon cut wire, the position of the threaded rod can be adjusted by rotating the textured cap, thereby controlling the clamping degree of the limit block on the wire.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] Example 1: A preferred embodiment of the lawnmower including a winding device provided by this utility model. Figure 1-4 As shown: A lawnmower with a winding device includes an L-shaped connecting rod 1, a rotating mowing part 3, and a lawnmower winding part 4. A handle 2 is fixedly installed at one end of the L-shaped connecting rod 1. The handle 2 is provided with a mowing button and a winding button. The rotating mowing part 3 is located at one end of the L-shaped connecting rod 1. The lawnmower winding part 4 is located at the bottom of the rotating mowing part 3.

[0024] The rotating mowing unit 3 specifically includes: a fixed housing 311, which is fixedly installed at one end of the L connecting rod; the fixed housing 311 has an opening 312 on its upper part, and a rotating motor 313 is fixedly installed inside the fixed housing 311. The output end of the rotating motor 313 extends to the outside of the fixed housing 311 through the opening 312.

[0025] The output end of the rotating motor 313 is fixedly connected to a protective top shell 314. A conductor coil 315 is fixedly installed on the bottom outer wall of the protective top shell 314. A wire hole 316 is opened on the conductor coil 315. A protective bottom shell 317 is fixedly installed on the bottom outer wall of the conductor coil 315.

[0026] In this embodiment, once the rotating motor 313 located inside the fixed outer casing 311 is started, it releases powerful force. Its output end acts like a tireless pusher, forcefully driving the protective top casing 314 to begin high-speed rotation. Driven by the rotating motor 313, the protective top casing 314 exhibits a stable and efficient rotational posture. The conductor coil 315, which is closely connected to the protective top casing 314, also quickly enters a rotating state under the drive of the protective top casing 314. During the rotation, the wire hole 316 on the conductor coil 315 ensures that the internal wiring will not become tangled or damaged due to rotation, providing an important guarantee for the stable operation of the entire lawnmower. At the same time, the protective bottom shell 317 also closely follows the rotation rhythm of the protective top shell 314, rotating at high speed together. With the coordinated rotation of the protective top shell 314, the guide coil 315 and the protective bottom shell 317, the nylon cutting rope 4112 connected to it is also driven. Under the power of high-speed rotation, it can easily cut various weeds and provide sufficient power to ensure that the nylon cutting rope 4112 rotates at high speed to carry out grass cutting operations. This powerful power output greatly improves grass cutting efficiency and can quickly handle large areas of grassland. The design of the protective top shell and the protective bottom shell provides good protection for the internal grass cutting components, preventing impact and damage from external objects.

[0027] Example 2: Based on Example 1, a preferred embodiment of the lawnmower including a winding device provided by this utility model is as follows: Figure 1-4 As shown: The lawnmower take-up unit 4 specifically includes: a rotating positioning sleeve 411, which is fixedly installed on the inner wall of the protective bottom shell 317; a motor fixing bracket 412, which is fixedly installed on the inner wall of the protective bottom shell 317; a positioning sleeve 415, which is fixedly installed on the inner wall of the protective bottom shell 317; a guide block 4114, which is fixedly installed on the inner wall of the protective bottom shell 317; and a take-up sleeve 4119, which is fixedly installed on the inner wall of the wire hole 316.

[0028] A rotating motor 413 is fixedly installed on the inner wall of the motor mounting bracket 412. A rotating rod 414 is fixedly connected to the output end of the rotating motor 413. The other end of the rotating rod 414 is rotatably connected to the inner wall of the protective bottom shell 317. The rotating rod 414 is movably installed inside the rotating positioning sleeve 411. A drive gear 4113 is fixedly sleeved on the outer wall of the rotating rod 414. A rotating shaft 416 is rotatably connected inside the positioning sleeve 415.

[0029] A rotating base plate 417 is fixedly installed on the top of the rotating shaft 416. A driven gear 418 is sleeved on the outer wall of the rotating shaft 416. An mounting sleeve 419 is fixedly installed on the top of the driven gear 418. The driven gear 418 is fixedly sleeved on the outer wall of the rotating shaft 416 through the mounting sleeve 419. A take-up reel 4111 is fixedly installed on the top of the rotating base plate 417.

[0030] The take-up reel 4111 has a nylon cut wire 4112 inside. The guide block 4114 has a rectangular opening 4115 on its upper part. A movable shaft 4116 is fixedly connected between the inner walls of the rectangular opening 4115. A guide pulley 4117 is sleeved on the outer wall of the movable shaft 4116. The nylon cut wire 4112 is fixedly installed on the outer wall of the take-up sleeve 4119. A fixed sleeve 4118 is fixedly installed on the top of the fixed sleeve 4118. A threaded sleeve 41111 is connected to the top of the fixed sleeve 4118.

[0031] The threaded sleeve 41111 has a threaded rod 41112 connected to its internal thread. One end of the threaded rod 41112 is fixedly fitted with a grinding cap, and the other end of the threaded rod 41112 extends through the threaded sleeve 41111 to the inside of the fixed sleeve 4118. The other end of the threaded rod 41112 is rotatably connected to a limit block 41113, and a fixed rubber strip is fixedly installed at equal intervals on the bottom outer wall of the limit block 41113.

[0032] In this embodiment, the rotating motor 413 starts, driving the rotating rod 414 to rotate. The rotating rod 414 rotates stably within the rotating positioning sleeve 411, and the driving gear 4113 on its outer wall rotates accordingly. The driving gear 4113 drives the driven gear 418 to rotate. The driven gear 418 is fixed to the rotating shaft 416 through the mounting sleeve 419, thereby driving the rotating shaft 416 to rotate within the positioning sleeve 415. The rotating base plate 417 at the top of the rotating shaft 416 and the take-up reel 4111 also begin to rotate. The nylon cut wire 4112 inside the take-up reel 4111 begins to wind around the take-up reel 4111. The nylon cut wire 4112 is guided by the guide pulley 4117 on the guide block 4114. The guide pulley 4117 can rotate flexibly on the movable shaft 4116. The rotating motor can provide stable power, and through the cooperation of the driving gear and the driven gear, the rotation speed and direction of the take-up reel are controlled. This allows the nylon cutting wire to be quickly and neatly retrieved after use, avoiding problems such as cable tangling and knotting, thus improving work efficiency. The reel design can accommodate a certain length of nylon cutting wire to meet the needs of different mowing areas.

[0033] Working principle: When the mowing button on handle 2 is pressed, the rotating mowing unit 3 begins to work, specifically as follows: Once the rotating motor 313 located inside the fixed housing 311 is started, it releases powerful force. Its output end acts like a tireless pusher, powerfully driving the protective top shell 314 to start rotating at high speed. Driven by the rotating motor 313, the protective top shell 314 exhibits a stable and efficient rotation posture. The conductor coil 315, which is closely connected to the protective top shell 314, also quickly enters a rotating state under the drive of the protective top shell 314. The wire hole 316 on the conductor coil 315 rotates... During the process, it ensures that the internal wiring will not become tangled or damaged due to rotation, providing an important guarantee for the stable operation of the entire lawnmower. Simultaneously, the protective bottom shell 317 closely follows the rotation rhythm of the protective top shell 314, rotating at high speed together. With the coordinated rotation of the protective top shell 314, the guide coil 315, and the protective bottom shell 317, the connected nylon cutting rope is also driven. Under the force of high-speed rotation, it can easily cut various weeds, whether delicate small grass or thick wild grass, all are chopped by the nylon cutting rope. This efficient lawnmower method greatly improves mowing efficiency, benefiting gardens. This greatly facilitates maintenance and lawn mowing. When the mower cord needs to be retracted, pressing the retract button on handle 2 starts the mower's winding section 4. Specifically, the rotating motor 413 inside the motor mounting bracket 412 starts, driving the rotating rod 414 to rotate. The rotating rod 414 rotates stably within the rotating positioning sleeve 411, causing the drive gear 4113 on its outer wall to rotate accordingly. The drive gear 4113 drives the driven gear 418 to rotate, and the driven gear 418 is fixed to the rotating shaft 416 via the mounting sleeve 419, thereby driving the rotating shaft 416 to rotate within the positioning sleeve 415. The rotating base plate 4 at the top of the rotating shaft 416... 17 and the take-up reel 4111 also begin to rotate. The nylon cut wire 4112 inside the take-up reel 4111 begins to wind around the take-up reel 4111. The nylon cut wire 4112 is guided by the guide pulley 4117 on the guide block 4114. The guide pulley 4117 can rotate flexibly on the movable shaft 4116. When it is necessary to fix the nylon cut wire 4112, rotate the threaded rod 41112 to make it move downward in the threaded sleeve 41111. The limiting block 41113 at the other end of the threaded rod 41112 and the fixing rubber strip on the bottom outer wall move downward to press the nylon cut wire 4112 and achieve fixation.
