| The applying of transplanter reduces the labor intensity of transplanting, steps the pace of change about labor-intensive to intensive agriculture, the transplanter plays a important role in transplanting agricultural production.2ZP-2 transplanter is a semi-automatic dibble-type transplanter, there are problems about the length of transplant orifice and power matching in practical use, which limit the promotion. The main contents of this paper include two part:one part is the analysis of the transplant orifice’s length, the other part is the calculation of power matching. The purpose is that the applicability of transplanter will be improved and the problem of power matching will be solved.In the process of researching of orifice’s length, the relation about drive ratio, motion characteristic parameter and slip ratio has achieved. To reduce the length of orifice, the way that change the chain wheel is proposed. The length of punching orifice for different chain wheel 2 is calculated with the formula which is deduced to calculate the transplant orifice’s length about the slip ratio in 0,10%,15%,20%,25% in Matlab GUI program, after the structural features of dibble and the dibble’s motion trail are analyzed. The simulation conclusion is that the range of orifice’s length, is 76mm to 107mm, is the shortest when Z2=24. According to the field trial, the range of length of orifice is the shortest when Z2-24 is verified, and the simulation has some reference value. The slip ratio of land wheel have greater effect on the punching orifice’s length.According to the professional standard, the matching power calculation formulas are elicited, the lifting force and tractive force are must be needed and achieved the data by the agricultural machinery kinetic parameter telemeter. The matching power calculation show that the matching power need more than 15kW, include the lifting power must be more than 15kW and tractive power must be more than 0.82kW. |
