Embodiment

[0031] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the application.

[0032] Please refer to Figures 1-8 The technical solutions provided by the application are as follows:

[0033] A gasoline multifunctional mower comprises an engine mounting frame 1, an engine 2 mounted on one side of the engine mounting frame 1, a driving shaft 3 connected to an output end of the engine 2 and penetrating through the engine mounting frame 1, a cutting cutter 4 connected to an end of the driving shaft 3 away from the engine 2, a moving wheel 5 rotationally connected between opposite ends of the engine mounting frame 1, a driving mechanism box 6 mounted on a side of the engine mounting frame 1 away from the engine 2, an end of the driving shaft 3 away from the cutting cutter 4 located inside the driving mechanism box 6, a movable driving mechanism 7 arranged in an inner cavity of the driving mechanism box 6 and achieving power connection and separation with the driving shaft 3 through movement, a rotating shaft 51 of the moving wheel 5 penetrating through the inner cavity of the driving mechanism box 6 and connected with the driving mechanism 7, and the driving shaft 3 driving the moving wheel 5 to rotate through the driving mechanism 7 when the driving mechanism 7 is power connected with the driving shaft 3.

[0034] As known from the above description, the effects of the application are as follows:

[0035] This invention adds a drive housing with an internal drive mechanism at the connection point between the engine and the drive shaft. This drive mechanism is movable, allowing the lawnmower to move under complex road conditions, such as when climbing hills. The drive mechanism can then engage with the drive shaft to form a power connection, enabling the drive shaft to drive the moving wheels and achieve automatic movement of the lawnmower, significantly reducing manual labor. Furthermore, under good road conditions, such as on flat ground, the drive mechanism can be separated from the drive shaft, preventing the drive shaft from rotating and thus avoiding unnecessary energy consumption due to the drive shaft's extra work.

[0036] Specifically, the drive mechanism 7 includes a movable drive wheel assembly 71, a driven wheel 72 fixed to the outer wall of the rotating shaft 51, and a movable tension wheel assembly 73;

[0037] The drive wheel assembly 71 includes two first concave mounting seats 711 with openings facing each other, and the first concave mounting seats 711 are mounted on the inner cavity side wall of the drive housing 6. The inner cavity of the first concave mounting seats 711 is slidably connected to a first rotating seat 712. The two first rotating seats 712 are rotatably connected to a drive rod 713. The outer wall of the drive rod 713 is fixedly connected to a worm gear 714 and a drive wheel 715.

[0038] The tensioner assembly 73 is disposed between the drive wheel assembly 71 and the driven wheel 72, and a chain 74 is connected between the drive wheel 71, the tensioner assembly 73 and the driven wheel 72;

[0039] The part of the drive shaft 3 located inside the drive housing 6 is a worm that cooperates with the worm gear 714.

[0040] As can be seen from the above description, the drive mechanism uses a worm gear meshing method for driving, which not only has strong driving force, but also facilitates separation and meshing between the two, making operation simpler. In addition, it uses chain drive for transmission, which is smooth and does not have elastic slippage. It can maintain an accurate average transmission ratio, has high transmission efficiency, does not require a large chain tension, has reliable transmission, and has strong overload capacity.

[0041] Specifically, the tension wheel assembly 73 includes two second concave mounting seats 731 with opposite openings, and the second concave mounting seats 731 are mounted on the inner cavity side wall of the drive housing 6. A limit rod 732 is fixed between the opposite ends of the inner cavity of the second concave mounting seats 731. A second rotating seat 733 is slidably connected to the outer wall of the limit rod 732. A rotating rod 734 is rotatably connected between the two sets of second rotating seats 733. A tension wheel 735 is fixed to the outer wall of the rotating rod 734. The chain 74 passes under the tension wheel 75.

[0042] From the above description, it can be seen that the second concave mounting seat and the limiting rod can limit the sliding distance and direction of the second rotating seat, so that when the driving wheel moves, the sliding resistance of the tensioner and the second rotating seat along the limiting rod is reduced due to the change of tension, thereby realizing the adjustment of the chain wheel tensioning.

[0043] Specifically, the limiting rod 732 is sleeved with a spring 736, and the spring 736 is located between the second rotating seat 733 and the end of the inner cavity of the second concave mounting seat 731.

[0044] From the above description, it can be seen that when the worm gear is engaged with the worm, the spring is in a compressed state due to the movement of the tensioner, and when the worm gear and the worm are separated, the tensioner can quickly return to the original position by the restoring force of the spring.

[0045] Specifically, the driving mechanism 7 further comprises a fixed limiting wheel assembly 75, the limiting wheel assembly 75 comprises a limiting rotating rod 751, and the limiting rotating rod 751 is rotatably connected between the inner cavity side walls of the driving mechanism box 6. The limiting rotating rod 751 is fixedly connected with a limiting wheel 752 on the outer wall, the limiting wheel 752 is located above the tensioner assembly 73, and the chain 74 passes below the limiting wheel 752.

[0046] From the above description, it can be seen that by setting the limiting wheel and passing the chain below the limiting wheel, the limiting wheel can limit the highest position of the chain, avoiding the chain from contacting the inner wall of the driving mechanism box during tensioning and causing wear.

[0047] Specifically, the driving mechanism box 6 is provided with a pull rope mechanism 8 connected with the driving wheel assembly 71 at the end away from the rotating shaft 51. The pull rope mechanism 8 moves the two first rotating seats 712 by pulling force, and the worm gear 714 is engaged with the worm to form the power connection between the driving mechanism 7 and the driving shaft 3.

[0048] From the above description, it can be seen that the pull rope mechanism provides the driving force for the movement of the driving mechanism, which is simple and labor-saving in overall operation.

[0049] Specifically, the pull rope mechanism 8 comprises a hollow fixed sleeve 81 and a steel wire pull rope 82. One end of the fixed sleeve 81 passes through the side wall of the driving mechanism box 6 and is located in the inner cavity of the driving mechanism box 6. The steel wire pull rope 82 is located inside the fixed sleeve 81 and is slidably connected with the fixed sleeve 81. The opposite ends of the steel wire pull rope 82 respectively penetrate the two ends of the fixed sleeve 81, and one end of the steel wire pull rope 82 penetrates out of the end of the fixed sleeve 81 and is connected with the end of the first rotating seat 712.

[0050] From the above description can be known: through the connection of the steel wire rope and the first rotating seat, the steel wire rope can be pulled to drive the first rotating seat to move, and the steel wire rope is slidably arranged in the fixed sleeve, which can avoid the contact between the steel wire rope and the driving machine box, the engine and other external components, and can make the steel wire rope move along a fixed route, so that the control is more convenient.

[0051] Specifically, the first rotating seat 712 is provided with a fixing ring 716 at the end portion, which cooperates with the steel wire rope 82.

[0052] From the above description can be known: through the setting of the fixing ring, the first rotating seat can be in firm contact with the steel wire rope, and the steel wire rope can be separated from the fixing ring conveniently.

[0053] Specifically, the driving machine box 6 is fixedly connected with a push rod 9 at one end of the end portion close to the moving wheel 5, the push rod 9 is provided with a brake handle 10 on the side wall away from the driving machine box 6, and one end of the steel wire rope 82 is connected with the brake handle 10.

[0054] From the above description can be known: through the setting of the push rod, the whole mower can be pushed to move conveniently, and the brake handle can be set to pull the steel wire rope more labor-savingly, and the brake handle is set at the end of the push rod, so that the operator can control it anytime and anywhere conveniently.

[0055] Specifically, the end of the push rod 9 away from the driving machine box 6 is in V-shaped structure, and the brake handle 10 is arranged on one end of the V-shaped structure.

[0056] From the above description can be known: the push rod is set in V-shaped structure, so that the operator can hold one end of the push rod with both hands to push, so that the movement of the mower is more stable, and some existing switches (such as the brake switch of the engine) can be installed on the other end.

The pull rope mechanism 8 moves the two first rotating seats 712 by pulling force, and makes the worm wheel 714 engage with the worm to form the power connection between the driving mechanism 7 and the driving shaft 3,

[0067] The pull rope mechanism 8 comprises a hollow fixed sleeve 81 and a steel wire pull rope 82. The materials of the fixed sleeve 81 and the steel wire pull rope 82 can be the material of the brake line of a bicycle. One end of the fixed sleeve 81 passes through the side wall of the driving box 6 and is located in the inner cavity of the driving box 6.

[0070] In this embodiment, the engine 2, the drive shaft 3 and other components in the mower are not improved, so the principle of the engine 2, the control switch and the like can be arranged in the same manner as the prior art.

[0071] The specific working principle of the above embodiment is as follows:

[0072] In use of the mower, the operator starts the engine 2, the engine 2 drives the drive shaft 3 and the cutting disc 4 to rotate, so as to cut the weeds through the cutting disc 4.

[0073] In the cutting process, when the road condition of the cutting machine is flat or dry, the operator directly pushes the cutting machine by holding the push rod 9, so that the moving wheel 5 moves to realize moving and cutting at the same time.

[0074] When the road condition of the cutting machine is a slope or a muddy road section, the operator swings the handle around the brake handle seat body by pulling the handle of the brake handle 10, so as to move the steel wire pull rope 82, move the two first rotating seats 712 along the first concave mounting seat 711, drive the driving rod 713 and the worm wheel 714 to move, make the worm wheel 714 engage with the worm on the drive shaft 3, and make the drive shaft 3 rotate to drive the worm wheel 714 to rotate.

[0075] And in the process of moving the driving rod 713, the change of the tension of the chain 74 will drive the tensioning wheel 735 and the second rotating seat 733 to move along the limiting rod 732, so as to change the position of the tensioning wheel 735 to adjust the tension of the chain 74, and ensure the normal work of the chain 74.

[0076] The rotation of the worm wheel 714 drives the driving rod 713 and the driving wheel 715 to rotate, and the driving wheel 715 drives the driven wheel 72 and the rotating shaft 51 to rotate through the chain 74, so that the moving wheel 5 can automatically rotate, so that the operator can operate more easily, and when the road condition returns to normal, the operator only needs to release the handle, the steel wire pull rope 82 returns to the original position under the action of the restoring force of the spring 736 and the gravity of the first rotating seat 712, so that the worm wheel 714 and the worm are separated, and the automatic walking is ended.
