This creation is that related what one kind is planted seedlings plant bed watering machinery structure,The watering machinery by bogie,Watering device and auxiliary device are formed,When the motor running on bogie,The driving gear of motor will drive first gear rotation,Because being to be linked with couple axle between the first gear of bogie two sides,Making the first gear of two sides can rotate synchronously,And rotating link chain group drives second gear operating simultaneously,Because the driving wheel of second gear and bogie links,It will make that watering machinery voluntarily advances or Hou is moved back,And the driving wheel of watering machinery can not be laterally moved by motor control rotation,When being intended to moving watering machine,By the first of auxiliary device,Two locating rods are pulled outward,Make first,The fixed block of two locating rods abuts each other positioning,And first,When two locating rods are pulled outward,The movable plate for pushing first locating rod institute's pivot solid is pushed down on,And then make the padded driving wheel of auxiliary wheel below movable plate,Because driving wheel emptied not with ground face contact,Watering machinery can be by the setting any direction movement person of auxiliary wheel at this time.本創作係有關於一種植苗植床澆水機結構，該澆水機係由驅動架、澆水裝置及輔助裝置所組成，當驅動架上之馬達運轉時，馬達的驅動齒輪將帶動第一齒輪轉動，因驅動架兩側之第一齒輪間係以連動軸連結，使兩側之第一齒輪可同步轉動，並同時轉動鏈條組帶動第二齒輪運轉，因第二齒輪與驅動架之驅動輪連結，將使澆水機自行前進或後退，而澆水機之驅動輪受馬達控制轉動無法做橫向移動，欲移動澆水機時，將輔助裝置之第一、二定位桿往外扳動，使第一、二定位桿之固定塊相互抵靠定位，而第一、二定位桿向外扳動時，將推動第一定位桿所樞固之活動板向下推，進而使活動板下方輔助輪墊高驅動輪，因驅動輪已騰空並未與地面接觸，此時澆水機可藉輔助輪之設置任意方向移動者。
