[0034] When in use, the gearbox body 1, as a core component, carries the operation of the entire transmission system.

[0035] Embodiment 2:

[0036] See also Figures 1 to 6As shown, a negative pole magnetic ring 23 is fixedly connected to the surface of the gearbox body 1, a core ring 24 is fixedly connected to the surface of the protective frame 2, and the surface of the negative pole magnetic ring 23 is overlapped with the bottom of the mounting frame 5, and the surface of the core ring 24 is overlapped with the bottom of the fixing frame 8, and the negative pole magnetic ring 23 and the core ring 24 are attached and connected to each other, and a control frame 25 is fixedly connected to the top of the protective frame 2, and a wire 26 is electrically connected to one side of the control frame 25, and the wire 26 and the core ring 24 are electrically connected to each other, and a control switch 27 is fixedly connected to the top of the control frame 25, and the control switch 27 and the wire 26 are electrically connected to each other, and the top of the control frame 25 is fixedly connected. A protection box 28 is connected, and the inner wall of the protection box 28 is sleeved on the surface of the control switch 27. The top of the protection box 28 is rotatably connected to a sealing cover 29. A first connecting gear is provided on the surface of the driving rod 3. The surface of the first connecting gear is meshedly connected with the second connecting gear. The bottom sides of the second connecting gear are meshedly connected with the third connecting gear. The bottoms of the two third connecting gears are meshedly connected with the fourth connecting gear. The inner walls of the two fourth connecting gears are fixedly connected to the two transmission rods respectively. The first connecting gear has 20 teeth, the second connecting gear and the two third connecting gears have 31 teeth, one of the fourth connecting gears has 13 teeth, and the other The fourth connecting gear has 27 teeth. The driving force will be transmitted to the first connecting gear through the driving rod. The rotation of the first connecting gear will drive the rotation of the second connecting gear. The first connecting gear has 20 teeth, and the second connecting gear has 31 teeth. The difference in the number of teeth will affect the speed ratio between the two. The speed of the second connecting gear will be 20 / 31 of the speed of the first connecting gear. The rotation of the second connecting gear will simultaneously drive the rotation of the two third connecting gears. The two third connecting gears also have 31 teeth each. Therefore, the speed ratio of the third connecting gear to the second connecting gear is also the same. The rotation of each third connecting gear will drive the rotation of a fourth connecting gear. The two fourth connecting gears have different numbers of teeth, one has 13 teeth and the other has 27 teeth.

Specifically, the speed of the fourth connecting gear with 13 teeth will be 31 / 13 of the speed of the third connecting gear to which it is connected, and the speed of the fourth connecting gear with 27 teeth will be 31 / 27 of the speed of the third connecting gear to which it is connected.

[0037] When in use, a negative pole magnetic attraction ring 23 is arranged on the surface of the gearbox body 1, and an iron core ring 24 is arranged on the surface of the protective frame 2, and a control frame 25 is arranged on the top of the protective frame 2. The control system inside the control frame 25 is connected to the iron core ring 24 through an electric wire 26. The iron core ring 24 is controlled to be powered on by a control switch 27 on the top of the control frame 25. The iron core ring 24 is powered on to form a positive pole magnetic attraction ring, so that the positive pole magnetic attraction ring and the negative pole magnetic attraction ring 23 are mutually adsorbed and connected, so that the sealed connection between the gearbox body 1 and the protective frame 2 constitutes an effective sealing barrier, which effectively prevents the intrusion of impurities such as moisture and dust, and prevents the gear assembly inside the gearbox from being damaged. The protective box 28 is sleeved on the surface of the control switch 27, and the sealing cover 29 is rotatably connected to the top of the protective box 28, which not only prevents external factors from interfering with and damaging the control switch 27, but also further enhances the overall sealing performance of the gearbox.

[0038] Embodiment three:

[0039] See also Figures 1 to 6 As shown in the figure, in the fields of agriculture and construction, the gearbox is the core transmission component of mechanical equipment, and its performance directly affects the working efficiency and service life of the entire equipment. However, traditional gearbox designs often have problems such as cumbersome disassembly and assembly, and insufficient sealing performance. These problems are particularly prominent in harsh working environments, such as muddy farmland and dusty construction sites. The gear components inside the gearbox are easily corroded by impurities such as moisture and dust, resulting in gear wear, jamming and other faults, which seriously affect the normal operation of the equipment.

[0040] Agricultural field: This gearbox is widely used in agricultural machinery and equipment such as combine harvesters and tractors, providing stable and reliable power transmission for the normal operation of the equipment.

[0041] Construction field: In construction machinery and equipment such as excavators and loaders, gearboxes also play an important role, ensuring the efficient operation of the equipment under various complex working conditions.

[0042] Quick disassembly and assembly: Through the snap-on or magnetic connection structure between the gearbox body 1 and the protective frame 2, the staff can quickly complete the disassembly and assembly of the gearbox without using tools. This not only simplifies the operation process, but also reduces labor intensity and improves work efficiency.

[0043] The negative pole magnetic ring 23 and the core ring 24 cooperate with each other to form an effective sealing barrier. When the control switch 27 is turned on, the core ring 24 is powered on to form a positive pole magnetic ring, which is adsorbed and connected with the negative pole magnetic ring 23, thus achieving a tight seal between the gearbox body 1 and the protective frame 2, effectively preventing the intrusion of impurities such as moisture and dust, and protecting the gear components inside the gearbox from damage.

[0044] The gearbox adopts a multi-stage transmission design. The servo motor 12 drives the transmission rod 13 to drive the first drive gear 14 to engage with the first transmission gear 15, thereby realizing the initial transmission of power. Subsequently, the second drive gear 17 on the movable rod 16 engages with the second transmission gear 18, further distributing the power to different transmission paths, ensuring the rapid disassembly and maintenance of the gearbox under different conditions.

[0045] The quick disassembly and assembly design makes the maintenance and replacement of the gearbox more convenient, reduces downtime and improves work efficiency.

[0046] The application of new sealing materials and structures has significantly enhanced the sealing performance of the gearbox, effectively preventing the intrusion of impurities such as moisture and dust, and extending the service life of the gearbox.

[0047] Working principle: When in use, the multiple groups of limit holes 7 opened on the plug-in frame 6 cooperate with the positioning plate 10, and the precise positioning and firm connection between the protective frame 2 and the gearbox body 1 are achieved through the insertion of the positioning rod 11, which not only simplifies the disassembly and assembly process, but also ensures the stability and reliability of the connection. The servo motor 12 is powered on, and the output end of the servo motor 12 is connected to the first drive gear 14 through the transmission rod 13. The meshing of the first drive gear 14 and the first transmission gear 15 realizes the initial transmission of power. The meshing of the second drive gear 17 on the movable rod 16 and the second transmission gear 18 further distributes the power to different transmission paths. Through the multi-stage transmission design, the connecting rod 1 9 is connected to the positioning plate 10 through the bearing bracket 20, and the threaded rod 21 at the front end thereof is threadedly connected to the inner wall of the positioning rod 11, so that the threaded rod 21 drives the positioning rod 11 threadedly connected on the surface to adjust the position, which not only realizes the stable connection between the parts, but also facilitates the disassembly and maintenance of the gearbox as a whole. The control switch 27 on the top of the control frame 25 controls the core ring 24 to be powered on, and the core ring 24 is powered on to form a positive magnetic ring, so that the positive magnetic ring and the negative magnetic ring 23 are mutually adsorbed and connected, so that the sealed connection between the gearbox body 1 and the protective frame 2 constitutes an effective sealing barrier, which effectively prevents the intrusion of impurities such as moisture and dust, and prevents the gear assembly inside the gearbox from being damaged.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
