DETAILED DESCRIPTION

[0031] The utility model will be described in further detail below in combination with the embodiment, it is understood that the orientation or position relationship indicated in the text "up", "down", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like is based on the orientation or position relationship shown in the drawing, only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element indicated must have a particular orientation, a particular orientation is constructed and operated, therefore, it can not be understood as the limitation of the utility model.

[0032] The embodiment proposes a double-crank gearbox for round baler, as shown in Figures 1 to 4 , including box body, the box body is similar to the existing round baler gearbox, the main body is circular structure, and the input end and the output end are appropriately extended. The box body adopts left and right split box structure, including main box 1 and box cover 2, and the main box 1 and the box cover 2 are detachably connected and fixed through bolts and positioning pins, facilitating subsequent maintenance operation.

[0033] ​The box is provided with an input shaft 3, a bevel gear 4, an output shaft 5 and a bevel gear 6. The two ends of the input shaft 3 are installed in the main box 1 through tapered roller bearings 11, and a bearing cover 7 is arranged for sealing the outer side of the bearing. The two ends of the output shaft 5 are installed in the main box 1 and the box cover 2 through tapered roller bearings 11 respectively, and a bearing cover 2 is arranged for sealing the outer side of the bearing. The input shaft 3 and the output shaft 5 are arranged perpendicular to each other. One end of the input shaft 3 is exposed to the box and is provided with a spline structure for connecting a power device to realize power input. The other end of the input shaft 3 is fixed with the bevel gear 4. Both ends of the output shaft 5 are exposed to the box and are provided with a spline structure for connecting with a crank to realize power output. The part of the output shaft 5 in the box is fixed with the bevel gear 6. The bevel gear 6 meshes with the bevel gear 4 to realize power transmission.

[0034] To optimize the structure, the bevel gear 4 and the input shaft 3 are integrally formed as a spline shaft, which can improve the carrying capacity of the spline shaft and make the power transmission stable and reliable. At the same time, the bevel gear 6 and the output shaft 5 are connected and fixed by bolts. The part of the output shaft 5 connected with the crank is easy to be damaged. At the same time, the size of the bevel gear 6 and the output shaft 5 is much larger than that of the bevel gear 4 and the input shaft 3. Here, the connection by bolts can facilitate the disassembly and replacement of parts.

[0035] A sealing ring 9 is arranged between the outer end of the input shaft 3 and the box, and a sealing ring 10 is arranged between the outer ends of the output shaft 5 and the box. To prolong the service life of the sealing ring and reduce the damage caused by the external environment, the bearing cover 7 of the present embodiment is provided with a retaining edge for protecting the sealing ring 9, and the bearing cover 8 is provided with a retaining edge for protecting the sealing ring 9.

[0036] As shown in Figure 1 The box of the present embodiment is provided with lifting screws 12 to facilitate the lifting of the gear box. A screw-in circular oil mark 13 is also arranged on the box to enable the operator to intuitively check the liquid level and color state of the lubricating oil or other working liquid.

[0037] To further optimize the structure, the bottom of the box of the present embodiment is fixed with a hole plate 14 by welding, which can conveniently, safely and reliably fix the gear box to the frame.

[0038] The box of the present embodiment is also provided with a pull rod hole 15, and a pull rod sleeve 16 is installed in the pull rod hole 15 through interference fit. The box is connected with the tractor pull rod through the pull rod sleeve 16. The pull rod sleeve 16 can be replaced after wear, which prolongs the service life of the gear box.

[0039] In use, the gear box is connected with a tractor, and a crank is installed, the tractor is started, power is realized through the input shaft 3, the bevel gear one 4, the bevel gear two 6 and the output shaft 5 to make the two-end cranks act simultaneously, the grass bundle density can be greatly increased, the grass bundle is more solid, and larger size can be baled, the working efficiency of the baling machine is improved, the transportation and storage cost is reduced, and the working requirements of the baling machine are fully met.

[0040] The above examples are only used for explaining the concept of the utility model, and are not limited to the protection of the utility model. Any non-essential modification of the utility model using the concept shall fall within the protection scope of the utility model.
