The utility model discloses a split type machine that leads, mainly solve exist among the prior art to lead the bulky weight of a machine heavier, the transportation of not being convenient for results in all higher problems of cost of transportation and cost of labor. This a split type machine that leads includes host computer part, control section, execution unit and trailer part, host computer part, execution unit, trailer part all are connected with high -speed joint head and heavily loaded connector simultaneously, the high -speed joint head of host computer part passes through hydraulic pressure oil pipe and can dismantle with the partial quick -operation joint of trailer with execution unit's quick -operation joint respectively and be connected, control section is connected with heavily loaded connector, and it can be dismantled and be connected with heavily loaded connector, execution unit's heavily loaded connector, the partial heavily loaded connector of trailer of host computer part respectively through signal control wire. By the proposal, the utility model discloses reached to make and led the less purpose of being convenient for transport and save cost of transportation and cost of labor of a quick -witted weight, had very high practical value and spreading value.
