摘要： PURPOSE:To obtain the subject device, having a tractive or a self-propelled machine body equipped with shanks sinking the side of their lower ends in the ground, further a push-up plate in the lower ends of the shanks and a soil discharger capable of carrying culture soil out of a field and capable of readily and easily performing operation to take out root parts of Chinese yams. CONSTITUTION:In a digger for Chinese yams for digging out the Chinese yams, cultivated and raised in a field, shanks (b) sinking the side of their lower ends in the ground is installed in a tractive or a self-propelled machine body (a) and a push-up plate (c) in the form of a long batten plate in the front and rear directions capable of tilting and lifting toward the rear is attached to the lower ends of the shanks (b). Endless chain type drillers(d) are arranged in front of the shanks (b) and installed in the machine body (a). A soil discharger (e) for laterally carrying soil, earthed up to a ridge (u) in the field and located above the push-up plate (c) when viewed from the rear to the rear is arranged in front of the shanks (b), supported by booms of the drillers (d) and installed in the machine body (a) to easily and readily and perform operation to take out the root parts (R) of the Chinese yams pushed up together with the soil of the ridge (u).

摘要： PURPOSE:To reduce tractive resistance applied to a rising plate by locating shanks supporting the rising plate at a position behind a chain digger unit set to the machine body and making its forward tilting angle controllable. CONSTITUTION:A rising plate (d) is divided into two parts composed of a front half unit (5a) and a rear half unit (5b) at a position a little inclined from the connecting part between the plate and shanks (c) and (c') towards the rear part and the divided two units are mutually connected rotatably using a hinge 50. The lower end side of a connecting rod 51 is connected to the rear half unit 5b and the upper end side of the connecting rod 51 is connected through an elevator (f) composed of engaging holes 51a made in serial form in the connecting rod 51 and a connecting pin 53 to an extended frame 52 extended rearwards from the upper end part of the shank (c).

摘要： PURPOSE:To prevent damage to root vegetables or occurrence of breakage thereof by moving a shank supporting a rising plate for cutting through the under part of a culturing row of the root vegetables forwards in a hole preliminarily dug using a chain digger unit. CONSTITUTION:A tractor (T) is driven and located so that a culturing row of root vegetables (P) may be straddled between a pair of chain digger units (b) and (b) set to the left and right of the machine body (a). A PTO shaft 11 is operated while lowering the machine body (a) by operating a lift arm 14 and the digger units (b) and (b) are operated by driving drive shafts 30 and 30 projecting from a mission case (M). A digging chain 38 of the digger unit (b) is inserted into the ground while digging the ground surface thereby. The tractor (T) is then driven while operating the digger unit (b) so as to dig a hole having a narrow width corresponding to that of the chain 38 using the digger units (b) and (b). A rising plate (d) supported between the respective lower end parts of a pair of right and left shanks (c) and (c) is moved forwards under the bottom of the culturing ridge of the root vegetable (P) at the same time. The root vegetables (P) and the soil of culturing ridge are raised from the upper surface of the plate (d) and projected from the ground surface thereby.
