Description

Paddy field working machine Technical Field The present invention relates to a paddy field working machine having a soil preparation device provided with a soil preparation rotor rotatably driven around a rotation axis extending in the lateral direction, in front of a seedling transplanting device. Background As a paddy field working machine in which a soil preparation device including a soil preparation rotor is disposed in front of a seedling transplanting device, a paddy field working machine configured as follows has been conventionally known. The paddy field working machine is configured such that a soil preparation device is disposed in front of a seedling planting device, a rotational power is input from a driving system of the seedling planting device to one end of a driving shaft of a soil preparation rotor, and soil preparation is performed on a farmland before the seedling planting operation by the seedling planting device by the driving rotation of the soil preparation rotor (see patent document 1). Prior art literature Patent literature Patent document 1 Japanese patent application laid-open No. 2017-35034 Disclosure of Invention Problems to be solved by the invention The paddy field working machine described in patent document 1 is useful in that a soil preparation rotor can be disposed at the front part of a seedling transplanting device to prepare soil for a farmland prior to a seedling transplanting operation. However, in such a structure, when a device having a large number of transplanting rows is used as the seedling transplanting device and a structure capable of dividing or folding the seedling transplanting device is used for storage and transportation, the soil preparation rotor cannot be divided or folded, and an operation such as disassembly is required, which leaves room for improvement. The present invention provides a paddy field working machine capable of dividing a soil preparation rotor by maintaining a state that the soil preparation rotor is attached to a seedling transplanting device. Solution for solving the problem The paddy field working machine of the present invention is characterized in that: seedling transplanting device connected and supported at the rear of the running machine body through lifting link mechanism and A soil preparation rotor which is driven to rotate around a rotation axis along the left-right transverse direction in front of the seedling transplanting device, The seedling transplanting device is provided with a seedling transplanting unit which is divided into a right side and a left side in the left-right direction, the seedling transplanting unit is composed of a plurality of seedling carrying parts, a plurality of seedling transplanting mechanisms and a transplanting frame, the plurality of seedling carrying parts are arranged in a row along the left-right direction, the plurality of seedling transplanting mechanisms are arranged in a way of corresponding to the seedling carrying parts, the transplanting frame supports the seedling carrying parts and the seedling transplanting mechanisms, The seedling transplanting unit is connected with the lifting link mechanism, The soil preparation rotor comprises a central rotating body part positioned at the central part in the left-right direction, and end rotating body parts arranged at the left-right sides along the rotation axis of the central rotating body part, wherein the end rotating body parts at the left-right sides are divided relative to the central rotating body part, The central rotating body part is supported by the lifting link mechanism, and the end rotating body parts on the left and right sides are supported by the corresponding seedling transplanting units on the left and right sides. According to the present invention, the soil preparation rotor is configured such that the left and right end rotor portions can be divided from the center rotor portion. The central rotating body portion is supported by the lifting link mechanism, and the left and right end rotating body portions are supported by the left and right corresponding seedling transplanting units. Therefore, even if the left and right end rotating body portions are divided with respect to the central rotating body portion, the central rotating body portion and the left and right end rotating body portions are supported by the lifting link mechanism and the corresponding seedling-transplanting units on the left and right sides, respectively, and the seedling-transplanting devices can be divided while maintaining the state of being attached thereto. Thus, in the paddy field working machine, the soil preparation rotor can be kept in a divided state while the soil preparation rotor is maintained in a state supported by the seedling transplanting device without the need of disassembling and assembling the soil preparation rotor, and the soil preparation rotor can be conveniently stored and transported.
