The invention discloses a
crop harvester and a parameter monitoring method thereof. The harvester comprises a moving part, and a power
system is arranged in the moving part; the ground breaking
assembly is integrally carried on the front side of the moving part, the ground breaking
assembly comprises a ground breaking
drill bit, material turning plates, a transmission box, a first power device and a second power device, the ground breaking
drill bit is connected with the transmission box through a connecting shaft, the second power device drives the ground breaking
drill bit to rotate in the circumferential direction of the ground breaking
drill bit, and the multiple material turning plates are fixedly installed on the connecting shaft; the side, away from the ground breaking
drill bit, of the transmission box is connected with the front side of the moving part in a pivoted mode, and the transmission box is driven by a first power device to rotate around a pivot shaft of the transmission box. The first power device drives the transmission case to conduct pivoting movement at different angles, adjustment of the ground breaking depth of the ground breaking
drill bit can be achieved, soil is loosened through the ground breaking drill bit, and under the condition that the soil is compact or hardened,
rhizome crops can still be easily excavated out to be harvested.
