[0002] Agricultural machinery plays a very wide role in agricultural production activities. It is needed at every stage of agricultural production, especially in the large-scale, mechanized planting areas of Northwest and Northeast my country. When cultivating, fertilizing, and spraying pesticides for cotton grown on a large scale in Xinjiang and corn grown on a large scale in Northeast China, the commonly used tractors and other machinery face many inconveniences because the chassis height of these crops is lower than their growth height after maturity. Utility Model Content

[0003] The purpose of this utility model is to provide a front drive axle raising device for agricultural machinery. By setting the raising device, the installation height of the wheel hub mounting plate is lower than the height of the machine chassis. This allows the height of the agricultural machinery chassis to be increased without changing the wheel hub size, so that the agricultural machinery chassis can pass smoothly over the top of the crops, realizing mechanized operations such as tillage, fertilization and spraying.

[0004] To achieve the purpose of this utility model, this utility model provides a front drive axle raising device for agricultural machinery, including: a front axle housing, a power mechanism installed inside the front axle housing, and wheel hub mounting plates connected to both ends of the front axle housing via a raising device. The raising device is configured with a downward bending structure, so that the installation height of the wheel hub mounting plates is lower than that of the front axle housing. A transmission component is installed inside the raising device, and the transmission component is used to powerly connect the power mechanism to the wheel hub mounting plates on both sides.

[0005] As a preferred technical solution of this utility model, the heightening device includes a connecting section and a heightening section. One end of the connecting section is connected to the side end of the front axle housing via a flange, and the flange is fastened with bolts. The side end of the heightening section is fixedly connected to the other end of the connecting section, and the bottom end of the heightening section is fixedly connected to the outer shell of the wheel hub mounting plate.

[0006] As a preferred technical solution of this utility model, the length of the connecting segment is set to 200mm-300mm.

[0007] As a preferred technical solution of this utility model, the length of the heightened section is set to 300mm-500mm.

[0008] As a preferred embodiment of this utility model, the transmission assembly includes a power shaft and a drive shaft. The power shaft is installed in the connecting section, and the drive shaft is installed in the heightened section. The power shaft and the drive shaft are connected by a first helical gear set.

[0009] As a preferred embodiment of this utility model, the power input end of the power shaft away from the end of the first helical gear set is connected to the power mechanism.

[0010] As a preferred embodiment of this utility model, the power output end of the drive shaft away from the end of the first helical gear set is connected to the rotating shaft of the hub mounting plate via a second helical gear set.

[0011] Compared with the prior art, this utility model provides a front drive axle raising device for agricultural machinery, which has the following beneficial effects:

[0012] By installing a heightening device, the installation height of the wheel hub mounting plate is lower than the height of the machine chassis. This allows for increasing the chassis height of agricultural machinery without changing the wheel hub size, enabling the chassis to pass smoothly over the top of crops and facilitating mechanized operations such as tillage, fertilization, and pesticide application. The connecting section is also lengthened compared to common machinery, facilitating the bolt tightening of the flange. The length of the heightened section can be selected and installed according to the maturity level of the crops, offering greater flexibility and a wider range of applications.
