Garbage separation and recovery machine for beach cleaning

A garbage separation and recovery machine for beach cleaning that has a vehicle body frame (51) towed by a vehicle and right and left wheels (53) secured to an axle (52) supported freely rotatably by the vehicle body frame (51), and separates sand and garbage from each other, comprising:

• a drum type sieve body (54) that is freely rotatably secured to the vehicle body frame (51);
• a driving gear (92) secured to the axle (52);
• a transmission mechanism (91) that transmits driving force of the driving gear (92) to the drum type sieve body (54), wherein the transmission mechanism (91) has switching means (95) that is configured to perform a switching operation between an automatic rotation mode in which the drum type sieve body (54) is rotated by rotational force of the wheel (53) and a manual rotation mode in which the drum type sieve body (54) is released from the rotational force of the wheel (53) and allowed to be manually freely rotatable;
• a clutch pipe (96) mounted relative to the vehicle body frame (51) in parallel relative to the axle (52);
• a sliding member (161) positioned on the clutch pipe (96), said sliding member (161) being operatively connected to an operation lever (100) to be slidable in an axial direction relative to the clutch pipe (96) in accordance with the manual operation of the operation lever (100);
• a driven gear (93) mounted on the sliding member (161);
• an urging member (175) operatively mounted between the sliding member (161) and the driven gear (93) for normally urging the driven gear (93) in the axial direction to an engaging position with the driving gear (92), wherein the driven gear (93) is freely slidably mounted relative to the clutch pipe (96) and engaged with/disengaged from the driving gear (92);
• and
• fitting pieces (94) mounted on the outer periphery of the drum type sieve body (54) and engaged with the driven gear (93) when the driven gear (93) is engaged with the driving gear (92).
