A digging blade for digging potatoes and the like is provided, and a guide means for guiding and rolling the potatoes that have been dug up and conveyed at the rear end of the conveyor is provided in a backward downward sloping shape. A dedicated working machine called potato digger, which has a plurality of pick-up rollers arranged in parallel at the front end of the conveyor and above the machine frame equipped with a crop storage tank from the rear end of the conveyor. A dedicated pick-up work machine called a potato picker that has a rotary bucket conveyor facing it, and a press in front of the conveyor for this pick-up work machine. A machine for exclusive use of excavation and picking up, which is called a potato harvester in which a roller, a coaster, and an excavating blade are arranged in this order, that is, a potato storage tank is picked up from a ridge at the same time and picked up at the same time There are generally known three types of working machines for excavation and picking up, which are transported and housed in each, and all of the working machines are towed by a tractor to travel while performing harvesting work.

By the way, since all the above-mentioned conventional working machines are dedicated machines, if a dedicated harvesting function (three ways of harvesting work) of each dedicated machine is required, all dedicated machines must be purchased. That is, since the potato digger dedicated to excavation is a machine that excavates two ridges at the same time by locating the excavation blade at the front end of the conveyor on the two ridges and excavating potatoes in the valley between the ridges. , There is an advantage that sun-dried (air-dried) can be done in the field so that soil can be easily dropped by leaving the moat potatoes left for several hours to several days. Is a working machine for efficiently picking up potatoes dug by the potato digger from the valleys of the ridges by locating a pick-up roller at the front end of the conveyer conveyor, and transporting them to the crop storage tank on the machine frame.

The potato harvester for excavating and picking up is located at the front end of the conveyer conveyor with the press roller, the coaster, and the excavating blade, and picks up the potatoes dug up at the same time. It is a working machine that conveys and stores the crops in a storage tank on the machine frame. Therefore, for root vegetables that should be picked up after being dried in the sun, two types of specialized machines, potato diggers and potato pickers, are needed. If root vegetables that should be picked up while digging up are potato harvesters. However, it takes a huge investment to purchase a dedicated machine with individual functions, and one farmer can buy all three types of specialized machines from the perspective of the harvest scale of root vegetables. The current situation is that it cannot be done.

[0005]

[Problems to be Solved by the Invention] The present invention has been made in view of such conventional circumstances, and the technical problem to be solved is that the conventional dedicated potato harvester can be used as a potato picker. The purpose is to provide an improved machine for harvesting agricultural products.
