[0020] The following describes the implementation of the present invention through specific embodiments. People familiar with this technology can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0021] according to Figures 1 to 3 This embodiment provides a drive shaft guard, including a guard mechanism. The guard mechanism is mounted and fixed to the bottom of the wheeled excavator via a mounting bracket and fits over the outside of each set of drive shafts. This protects the high-speed rotating drive shafts during operation, preventing sugarcane leaves and other weeds and branches from contacting or becoming entangled with the drive shafts, thereby enabling smooth sugarcane harvesting and loading. The specific implementation structure of the guard mechanism and mounting bracket is described below.

[0022] The guard plate mechanism includes a main body 100 and a sliding part 200. Both the main body 100 and the sliding part 200 are circular tubes with a hollow structure. The length of the main body 100 meets the basic requirements for the use of the guard plate mechanism, and the sliding part 200 is used to adjust the length of the entire guard plate mechanism so that drive shafts of different models and lengths can be wrapped inside. When in use, the sliding part 200 is set at one end of the inner side of the main body 100 and the two are connected and fixed. The structure of the main body 100 and the sliding part 200 specifically includes:

[0023] The main body 100 and the sliding part 200 are both composed of two groups of symmetrically distributed sub-parts connected to each other, that is, the main body 100 and the sliding part 200 both adopt a split structure and can be freely disassembled and installed on the outside of the transmission shaft. The edge of the sub-part is provided with a flange portion 101 with an integral structure therewith, and the flange portion 101 is provided with a mounting hole, and the sub-parts are connected and fixed to each other by respective flange portions 101 and bolt assemblies; wherein, the sliding part 200 is located on the outside of the main body 100, and the flange portion 101 of the sliding part 200 is connected to the flange portion 101 of the main body 100. At the same time, a plurality of mounting holes or elongated holes 304 are provided on the sliding part 200 to facilitate adjustment of the length after connection with the main body 100;

[0024] At the same time, the flange portion 101 is also provided with side ears 102 for connecting with the mounting bracket, and the side ears 102 are vertically distributed at the edge position;

[0025] In order to facilitate installation on the outside of the drive shaft of the wheeled excavator, the main body 100 and the sliding part 200 are provided with a notch-structured paving portion 201 near the inner end of the drive shaft of the wheeled excavator. The paving portion 201 can match the shape of the drive shaft and other components, and has a better protective effect after installation.

[0026] The mounting bracket includes two sets of hanging parts 301 and a set of fixing parts 302 for connecting the hanging parts 301. The hanging parts 301 and the fixing parts 302 adopt a panel structure, wherein:

[0027] The upper portion of the lifting member 301 is provided with a plurality of fixing holes 303, and the lower portion of the lifting member 301 is provided with a group of elongated holes 304 distributed along its length. The lower end of the lifting member 301 is connected to the side ears 102 of the guard plate mechanism through the elongated holes 304. The elongated holes 304 are used to adjust according to the distribution position of the transmission shaft. The upper end of the lifting member 301 is connected and fixed to the bottom of the wheeled excavator through the fixing holes 303 and the connecting member 400.

[0028] The fixing member 302 is connected to the two groups of hanging members 301 respectively. One end of the fixing member 302 is provided with multiple groups of fixing holes 303, and the other end of the hanging member 301 is provided with a group of long holes 304 distributed along its length. The arrangement of the long holes 304 is also for easy adjustment during installation. After it is connected to the hanging member 301, the mounting bracket and the guard plate mechanism form a parallelogram structure, and the overall assembly structure is stable.

[0029] The connecting member 400 adopts an L-shaped structure, and fixing holes 303 or long holes 304 are respectively provided on both sides of the connecting member 400. One side is connected to the lifting member 301, and the other side is connected to the wheeled excavator. At the same time, a mounting seat 401 is also provided at the connection position between the connecting member 400 and the wheeled excavator. The mounting seat 401 is welded and fixed on the wheeled excavator. A wire hole is provided at the bottom of the mounting seat 401 and is connected to the connecting member 400, so that the connection structure at this position is not easy to fall off.

[0030] The above description is only a preferred embodiment of the present invention. As long as the technical solution of the present invention is achieved by basically the same means, it falls within the scope of protection of the present invention.
