Problems solved by technology

[0005] However, the leveling rotating body is configured so that it cannot be lifted from the (set) height position where the work is performed without relying on the lifting operation of the operating lever. If there is a sudden push of the ground leveling rotor due to upward bulge, the ground leveling rotor may be damaged

Embodiment Construction

[0028] Such as figure 1 As shown, the rice transplanter 1 is provided with the engine 2, the power transmission part 3, the planting part 4, and the elevating part 5. The planting unit 4 is connected to the machine body via the lifting unit 5 , and can be raised and lowered in the vertical direction by the lifting unit 5 . Power from the engine 2 is transmitted to the planting unit 4 via the power transmission unit 3 . The rice transplanter 1 plants rice seedlings in a field through the planting unit 4 while traveling by the drive of the engine 2 .

[0029] The driving force from the engine 2 is transmitted to the PTO shaft 7 via the transmission 6 at the power transmission unit 3 . The PTO shaft 7 protrudes rearward from the transmission 6 . The planting part 4 is driven by transmitting power from the PTO shaft 7 to the rice planting transmission case 8 via the universal joint. Further, a drive shaft 9 is provided toward the rear from the transmission 6 , and driving forc...

Abstract

Provided is a technology capable of preventing damage of a soil preparation device even when the soil preparation device is suddenly pushed up from a section that is in contact with the ground while the soil preparation device is working. The rice transplanter (1) is provided with a soil preparation device (20) for preparing headland soil. The soil preparation device (20) is supported so as to be capable of being raised and lowered with respect to a planting unit (4) via a support link mechanism (30) that is provided on the planting unit (4). The support link mechanism (30) comprises an operating lever (40) for raising and lowering the soil preparation device (20) via the support link mechanism (30). The operating lever (40) allows upward movement of the soil preparation device (20) that does not depend on operation of the operating lever (40).

Description

technical field [0001] The present invention relates to the technology of rice transplanter. Background technique [0002] The ground leveling device of the rice transplanter disclosed in Japanese Patent Application Laid-Open No. 2008-228598 has: a ground leveling rotating body installed on a drive shaft driven by rotation, a reinforcing strut interposed between the drive shaft and the planting part, and a The operating lever for raising and lowering the height of the leveling rotating body (working position). [0003] During the operation and running of the rice transplanter, even if stones or foreign objects collide with the soil leveling device, thereby exerting external force on the soil leveling rotating body of the soil leveling device from the front and rear directions, the support of the struts is strengthened to prevent the ground leveling body from being damaged. Broken due to bending. [0004] Patent Document 1: Japanese Patent Laid-Open No. 2008-228598 [0005...
