Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rice transplanter in which a preliminary seedling stand is provided on an inclined upper part of an inclined seedling stand that is movable in a reciprocating direction in the lateral direction so as to be movable in the lateral direction.

In the spare seedling rack device of such a rice transplanter, since the spare seedling rack is separated from the inclined seedling rack, it is easier to move horizontally compared to a device that is integrated with the tilted seedling rack. It has the advantage that the drive mechanism of the device can be easily downsized, and the positioning of both seedling stands in the lateral direction when replenishing seedlings can be easily and quickly performed by moving the spare seedling stand.

The present invention is an improvement of the spare seedling rack device for rice transplanters which has the above-mentioned advantages, and its purpose is to prevent the spare seedling rack from accidentally moving laterally during operation. Although the table is configured to be movable and fixed and unfixed, the rice transplanter can easily perform horizontal movement work to align the standby seedling stand with respect to the inclined seedling stand when replenishing seedlings through a series of operations. The aim is to provide a spare seedling stand device.

Next, an embodiment of the present invention will be described based on the drawings. FIGS. 1 and 2 show the overall structure of a riding rice transplanter, and FIGS. 3 and 4 show the structure of its main parts.

The riding rice transplanter has a front part of a riding machine 10 which is equipped with a pair of left and right front wheels 6, 6, one steering rear wheel 7, a riding driving part 8, and a driving part 9, and is movable in a reciprocating manner in the lateral direction. A four-row type planting device 1 having a rear inclined seedling rack 1A is arranged in a row in a vertically movable manner, and a frame F of the planting device 1 is attached to the inclined upper part of the sloped seedling rack 1A of the planting device 1. A spare seedling stand device A is provided as a mounting portion.

The planting device 1 interlocks with the horizontal movement of the slanted seedling rack 1A, and plants the seedlings between the seedling take-out port 1a formed at the lower end of the slanted seedling rack 1A and the mud surface leveled by the float 1B. By cyclically operating the claws 1C, the placed seedlings are taken out and planted in unit quantities.

The above-mentioned preliminary seedling rest device A moves its seedling mounting surface 2A to the inclined seedling rest 1A by vertically swinging around a horizontal shaft 5 provided close to the inclined upper end side of the inclined seedling rest 1A. Spare seedlings that can be freely switched between a seedling supplying position in which the seedlings are placed on an inclined extension surface and the preliminary seedlings are slid onto the inclined seedling placement table 1A, and a seedling receiving posture in which the seedling placement surface 2A is placed horizontally. A table 2 is attached to the frame F so as to be movable in the lateral direction including the horizontal shaft 5.

The structure for attaching the preliminary seedling stand 2 to the frame F includes attaching wheels 12 for lateral movement to the mounting bracket 11 of the horizontal shaft 5, and attaching wheels 12 for movement to the frame F with respect to these wheels 12. A rolling wheel 1 on which a guide rail 13 and a lateral movement rail 14 attached to the lower surface of the swinging free end of the preliminary seedling stand 2 are placed.
5... group is added.

An engaging protrusion 3B that can freely engage and disengage from the wavy engagement surface 3A provided on the mounting bracket 11, and prevents the lateral movement of the preliminary seedling stand 2 by engaging; A spring 3C for biasing movement in the engagement direction is attached to the guide rail 13 to constitute a fixing mechanism 3 capable of fixing and unfixing the reserve seedling stand 2. An operating lever 4 is provided which can move the preliminary seedling rest 2 laterally by inserting and engaging the rail 14 on the side of the seedling rest 2 and swinging in the left-right direction. By connecting to the engaging protrusion 3B of the fixing mechanism 3 through the fixing mechanism 3 and moving the operating lever 4 in its longitudinal direction, the fixing mechanism 3 is switched and the operating lever 4 is operated to swing in the vertical direction. By this,
The preliminary seedling stand 2 is configured to change its posture.

In summary, the preliminary seedling rest device of the rice transplanter according to the present invention, as explained at the beginning, allows the preliminary seedling rest 2 to be vertically swung around the horizontal axis 5.
The seedling placement surface 2A can be switched between a seedling supplying posture in which the seedling placement surface 2A is located on the inclined extension surface of the inclined seedling platform 1A or a slope close to it, and a seedling receiving posture in which the seedling placement surface 2A is located horizontally or on a substantially horizontal surface. and furthermore,
A mechanism 3 for fixing the lateral movement to the preliminary seedling platform 2 is provided, and the preliminary seedling platform 2 is provided with a mechanism 3 for fixing the horizontal movement.
The single lever 4 for operating the lateral movement and vertical swinging of the locking mechanism 3 is also used as the lock release lever of the locking mechanism 3, so that it has the following advantages.

That is, the fixing mechanism 3 can be operated by using the operation lever 4 for moving the spare seedling stack.
Although the presence of the fixing mechanism 3 prevents accidental lateral movement of the spare seedling rack 2 during work, the positioning of both seedling racks can be done by a series of operations on a single operating lever 4. By being able to release the fixation and move the spare seedling stand to a desired position, it has become possible to simplify and streamline the manual operations involved in seedling supply work. In particular, by vertically swinging the preliminary seedling tray 2 around the horizontal axis 5, the seedling loading surface 2A is positioned on the inclined extension surface of the inclined seedling tray 1A or an inclined surface close to it, so that the seedling loading position is parallel to the seedling loading position. Since it is configured so as to be switchable between the position of receiving the seedlings and the position of receiving the seedlings located on a substantially horizontal plane, it is possible to supply seedlings very advantageously.
