The square groove 71 is opened on the top of the gear box top cover 2, and the bottom of the sliding plate 72 is slidably connected to the top of the gear box top cover 2. A connecting plate 73 is fixedly connected to the bottom of the sliding plate 72, and a rack 74 is fixedly connected to the end of the connecting plate 73 away from the sliding plate 72. A support plate 75 is slidably connected to the bottom of the rack 74. A gear 76 is provided on the top of the support plate 75, and the side surface of the gear 76 is meshed with the rack 74.

[0029] like Figure 3As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the top of the support plate 75 is fixedly connected to the inner wall of the gear box body 1, the top of the support plate 75 is fixedly connected to a fixing plate 77, a telescopic airbag 78 is provided on one side of the fixing plate 77, and a push plate 79 is fixedly connected to the end of the telescopic airbag 78 away from the fixing plate 77. This design is conducive to better operation of the heat dissipation structure 7 and achieves a rapid heat dissipation effect.

[0030] like Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, the number of racks 74 is set to two, and they are symmetrical to each other along the vertical center axis of the support plate 75, and the side of the push plate 79 away from the telescopic airbag 78 is fixedly connected to the side of a rack 74. This design is conducive to the push plate 79 pushing the rack 74 to move when it moves.

[0031] like Figure 3 As shown, as a preferred embodiment, on the basis of the above method, further, the number of sliding plates 72 is set to two, and they are symmetrical with each other along the vertical center axis of the gear box top cover 2, and the area of ​​the sliding plate 72 is half of the area of ​​the square groove 71. This design is conducive to the sliding plate 72 covering the square groove 71 and can also be opened at the same time.

[0032] like Figure 3-Figure 4 As shown, as a preferred embodiment, on the basis of the above-mentioned manner, further, the gearbox top cover 2 is provided with a lubrication structure 8, the lubrication structure 8 includes a lubricating oil tank 81, the lubricating oil tank 81 is fixedly penetrated through the top of the gearbox top cover 2, an oil tank cover 82 is provided on the top of the lubricating oil tank 81, an oil tank cover 82 is provided on the top of the oil tank cover 82, an oil inlet groove 86 is opened on the top of the oil tank cover 82, and a protective plug 83 is provided inside the oil inlet groove 86. This design is conducive to lubricating the gears in the gearbox and improving the working speed.

[0033] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, further, an oil spray head 84 is provided at the bottom of the lubricating oil tank 81, and a baffle 85 is fixedly connected to one side of the rack 74. The baffle 85 is located below the oil spray head 84 and is in contact with the oil spray head 84.

[0035] Working principle: when the gear box is working, the gears inside the gear box body 1 will rotate continuously. At this time, the temperature inside the gear box will rise, and the telescopic airbag 78 will expand due to the heat. When the telescopic airbag 78 expands, it will push the push plate 85, and the push plate 85 will push the rack 74 on this side. When the rack 74 moves forward, it will rotate with the gear 76, thereby causing the rack 74 on the other side to move. At this time, the two racks 74 will move towards each other, and the two sliding plates 72 will move towards each other through the connecting plate 73. In this way, the square groove 71 of the gear box top cover 2 will leak out, and the internal heat will be dissipated. When the rack 74 moves, the baffle 85 will also move with it, thereby leaving the surface of the oil spray head 84, so that the lubricating oil inside the lubricating oil tank 81 will drip downward through the oil spray head, dissipating the heat for the gear while lubricating it, preventing the lubricating oil on its surface from evaporating, causing the gear to jam when working. The staff can refuel through the oil inlet groove 86 on the oil tank cover 82.

[0036] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method.
