Abstract

The present invention relates to a sowing-type working machine, which simplifies the structure when the sowing-type working machine is equipped with a ground leveling device for leveling the surface of a farmland. The working device (5) is supported on the link mechanism (3) connected to the rear part of the machine body to swing freely up and down, and the leveling device (53) is positioned between the machine body and the working device (5). (81, 83) are supported on the operating device (5) freely in a lifting manner. Through the electric actuator (56), the leveling device (53) can be freely driven up and down to the working position where it is grounded on the farmland surface and prepares the farmland surface, and to the non-working position where it is away from the farmland surface to the upper side. A working operation part (120) is installed on the working device (5), which makes the electric actuator (56) work through manual operation, so that the land preparation device (53) can be lifted to the working position and the non-working position.

Description

technical field [0001] The present invention relates to a planting type work machine, which is provided with working devices such as a rice transplanting device and a seeding device at the rear of the machine body, and a soil leveling device for leveling the surface of an agricultural field. Background technique [0002] A riding-type rice transplanter is an example of a planting-type working machine, and Patent Document 1 discloses that there is a riding-type rice transplanter in which a soil leveling device is supported by the rice transplanting device so as to be located between the machine body and the rice transplanting device. [0003] The leveling device of Patent Document 1 includes: a drive shaft that is supported in the left-right direction and driven to rotate; a leveling body that is mounted on the drive shaft and rotates integrally with the drive shaft; Driven in rotation, thereby preparing the surface of the farmland. Thereby, while leveling the surface of the...
