PROBLEM TO BE SOLVED: To solve a problem in which it takes time to set delivery quantity and a load on a worker is high since an oscillation fulcrum for adjusting the delivery quantity of a pump provided at a middle of an oscillation crank is moved by rotation of a screw rod in a conventional pump drive device having one end of the oscillation crank connected to a reciprocating moving body driving a reciprocating drive type pump provided on a soil disinfecting machine, having an eccentric cam connected to another end of the oscillation crank, and driving the reciprocating drive type pump by driving and rotating the eccentric cam via the reciprocating moving body. SOLUTION: The device has a structure connecting an adjustment lever 44 to the oscillation fulcrum 41 and quickly moving a position of the oscillation fulcrum 41 by slide operation of the adjustment lever 44 in a longitudinal direction of the oscillating crank 40. Delivery quantity of the reciprocating drive type pump 29 is adjusted by controlling reciprocating motion of the reciprocating moving body 37. COPYRIGHT: (C)2008,JPO&INPIT
