Description

[Detailed Description of the Invention] The present invention is configured to raise and align the main seedling rack for supplying seedlings to the seedling planting device with respect to the machine-side spare seedling racks provided in multiple upper and lower stages. Regarding Tanaeki.

In order to configure the main seedling rack so that it can be positioned at a constant or almost constant tilted position with respect to the preliminary seedling racks at each stage, a single drive mechanism using a ten-row four-link mechanism allows the main seedling rack to be positioned at a constant or almost constant tilted position. It is possible to raise and lower the platform.

According to this structure, since the tip of the main seedling stand draws an arcuate trajectory, space is required in the longitudinal direction of the machine to draw an arcuate trajectory. The disadvantage is that the turning radius becomes larger and the number of manual planting points at the edge of the field increases.

The present invention aims to eliminate the above-mentioned drawbacks.

A characteristic feature of the rice transplanter of the present invention is that it is provided with an elevating mechanism that vertically raises the main seedling tray, so that it can be positioned in a constant inclined posture with respect to the preliminary seedling trays of each stage. At a certain point, such precepts produce the following effects.

In other words, a lifting mechanism is provided to vertically raise the main seedling rest, so that the main seedling rest can be positioned at a constant tilt with respect to the spare seedling rest at each stage. The tip of the seedling pedestal draws a vertical trajectory, and as the main seedling pedestal rises, the tip of the seedling pedestal draws an arcuate trajectory, unlike the case where the tip of the seedling pedestal draws an arcuate trajectory.This eliminates the need for space in the longitudinal direction of the machine, making it possible to plant seedlings. By bringing the entire device closer to the main machine, the front and rear length of the machine can be shortened, and the turning radius of the machine at the edge of the field can be reduced, reducing the manual effort required to plant seedlings at the edge of the field. It's arrived.

Embodiments of the present invention will be described below with reference to the drawings.

At the rear of the tractor body 1, six seedling planting devices 2...
..., a rice planting device equipped with a main seedling platform 3 that supplies seedlings to the seedling planting device 2 while reciprocating from side to side as the seedling planting device 20 rotates, and a float 4 that floats and supports the machine body. The machine 5 is detachably connected via a lifting mechanism 6 that vertically raises it.

A spare seedling storage device 8 is provided above the left and right rear wheels 7, 7 of the tractor for storing spare seedlings to be supplied to the main seedling rack 3, and this storage device 8 stores three spare seedlings. Stand 9
......are arranged one above the other.

To configure the elevating mechanism 6, a rice transplanter mounting bracket 12 is provided along the guide rail 10 on the tractor side and is moved up and down by a hydraulic cylinder 11.
2, the rice transplanter 5 is connected and fixed to the tractor control section 13, and a hydraulic circuit control valve 15 for the cylinder 11 is controlled by a lever 14 attached to the tractor control section 13, thereby forming a cylinder control mechanism. 14, the rice transplanter 5 moves vertically in parallel (vertically)
It's supposed to be done.

The main seedling resting table 3 is configured to be inclined from the rear side of the machine toward the front and upper side, and when the elevating mechanism 6 is operated, the main seedling resting stand 3 maintains the inclined position at a constant or almost constant position. and the seedling receiving opening 3a of the main seedling resting stand 3 is connected to each of the preliminary seedling resting stands 9.
・The position closest to the seedling supply port 9a of the main seedling tray 3 is moved to the position closest to the seedling supply port 9a of the main seedling tray 3 by controlling the lifting mechanism 6. It is configured so that it can be aligned.

Therefore, when supplying seedlings from the preliminary seedling storage device 8 to the main seedling rack 3, the elevating mechanism 6 is used to raise the main seedling rack 3, and the seedling receiving port 9a is opened to the seedling supply port 9a. The eyes 3a are aligned and the spare seedlings are pushed out from the spare seedling rack 9 towards the main seedling rack 3. According to the above configuration, which of the spare seedling racks 9... However, since the main seedling rack 3 can be positioned in a constant or almost constant tilted position, even when replenishing from any of the spare seedling racks 9, the supplied seedlings may not slide smoothly or suddenly. The seedlings will not fall off and cause damage to the seedlings.

According to the above-mentioned elevating mechanism, since the rice transplanter 5 is moved in parallel while being moved as a whole, the amount of movement of the seedling planting device, which is heavy in weight, can be suppressed to a small amount.

As shown in FIG. 3, the spare seedling storage device 8 is constructed by tilting the spare seedling rest 9 in the direction of supplying the main seedling rest 3 to facilitate the seedling replenishment operation. , each seedling supply port 9a, . . . may be provided with an opening/closing door 16 to prevent the seedlings from falling off during regular storage.
