The entire transmission structure is compact and easy to assemble and disassemble.

[0041] The specific working method of the present invention is as follows: power is transmitted from the input shaft and split into two parts: one part is transmitted from the oil pump input gear, which has an interference fit with the input shaft, to the oil pump output shaft, thereby driving the oil pump; the other part is transmitted through the input shaft to the large bevel gear on the intermediate shaft. The large bevel gear is splined to the intermediate shaft. The power is then split again by a gear on the intermediate shaft. One part is transmitted to the main output gear, which is splined to the main output shaft. The main output shaft outputs power from both sides to drive the compression and baling device; the other part is transmitted to the idler gear, and then to the output shaft. The output shaft outputs power from both sides to drive the pickup and feeding device. The transmission box features a compact structure, easy assembly and disassembly, reliable operation, and low noise.
