Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is used for a riding seedling planting machine equipped with a fertilizing device, and is intended to improve weight balance while effectively utilizing space.

(Prior Art) In a conventional seedling transplanter with a fertilizing device, the fertilizing device is provided further rearward than the seedling planting device. Incidentally, there are some publications in which the fertilizer tank of the fertilization device is installed before the seedling stand of the seedling planting device, but this has not yet been put into practical use.

(Problem to be Solved by the Invention) In a riding seedling transplanter, which is configured with a seedling planting device connected to the rear of a traveling vehicle body, when the seedling planting device is lifted up, the center of gravity moves backward by a wide distance and moves forward. floats up and does its own thing. If the fertilizing device is installed after the seedling planting device, its uplift will be further increased. In order to solve this problem, a balance weight is placed in front of the traveling vehicle body, but this increases the overall weight and increases the tendency to damage the plowing platform, which is not desirable.

(Means for Solving the Problems) The present invention solves the above problems and utilizes space effectively to realize a small and compact passenger seedling planting device. 1, a seedling planting device 6 connected to the rear of the traveling vehicle body 1, a fertilizing device 15 that applies fertilizer at the same time as planting seedlings, and a preliminary seedling platform 29,
The fertilizer tank 16 of the fertilizer application device 15 is provided between the seat 2 and the seedling stand 12 of the seedling planting device 6 when viewed from the side, and the spare seedling stand 29 is provided above the fertilizer tank 16 and at the front of the vehicle body 1 when viewed from the side. This seedling transplanter with a fertilization device is characterized in that it is installed on a traveling vehicle body 1 so as to move between the two directions.

(Function) Since the present invention is configured as described above, during the seedling planting work, the preliminary seedling platform 29 is used while being moved to the front part of the traveling vehicle body 1.

That is, the seedling planting device 6 moves forward in the field while being pulled by the traveling vehicle body 1 with the preliminary seedling platform 29 positioned in front, and the planting rod 14 takes out the seedlings on the seedling platform 12 and places them on the mud surface. Transplant. At the same time, the fertilizer applicator 15 dispenses the fertilizer from the fertilizer tank 16 and applies the fertilizer next to the seedlings to be transplanted.

When there are fewer seedlings on the seedling platform 12, the forward movement of the traveling vehicle body 1 and the operation of the seedling planting device 6 are stopped, the preliminary seedling platform 29 is moved to the top of the fertilizer tank 16, and the preliminary seedlings on the preliminary seedling platform 29 are moved. - is replenished onto the seedling stand 12. Furthermore, when the amount of fertilizer in the fertilizer tank 16 becomes low, the fertilizer is replenished into the fertilizer tank 16 while the preliminary seedling platform 29 is moved to the front of the traveling vehicle body 1.

(Effect) As described above, according to the present invention, while the riding seedling transplanter is moving, the fertilizer tank 16 is located in front of the seedling platform 12, and the preliminary seedling platform 29 is located at the front of the traveling vehicle body 1. The center of gravity is closer to the front, providing good stability. Further, even if a balance weight is used to adjust the center of gravity in this way, it is only necessary to use a very small amount, and it hardly contributes to an increase in the overall weight.

Further, since the spare seedling stand 29 when moved rearward is located above the fertilizer tank 16, the space is effectively utilized and the overall length is short and compact.

(Example) Next, the present invention will be explained in detail. As shown in the figure, a traveling vehicle body 1 includes a seat 2 slightly rearward from the center, and an engine 3 under the seat 2 drives a pair of front axles 4 and rear wheels 5. 6 is this running vehicle body 1
A riding seedling planting machine is constructed by connecting the rear part of the machine with a pair of upper and lower links 7. A rod 10 extending from a cylinder 9 is connected to the arm 8 of the upper link 7, and when the rod 10 is pushed out, the rear end of the link 7 rises and the seedling planting device 6 is lifted up. The seedling planting device 6 includes a gear box 11 in the center, a seedling platform 12 that tilts forward and reciprocates left and right on top of the gear box 11, and a float 13 that slides on the mud surface as the vehicle body 1 moves forward. It is composed of six planting rods 14 that cut off the seedlings from the seedling stand 12 and insert them onto the mud surface.

The fertilizer application device 15 is composed of a fertilizer tank 16, a feeding rotor 17 below the fertilizer tank 16, a hose 18, and a furrower 19. The fertilizer tank 16 is attached to a support 20 at the rear of the traveling vehicle body 1, and is located between the seat 2 and the seedling stand 12 when viewed from the side. The furrower 19 is fixed to the float 13 next to the planting rod 14. The hose 18 is provided so as to extend from below the feed rotor 17 to the groove cutter 19, and is configured to guide the fertilizer fed out by the feed rotor 17 to the groove made by the groove cutter 19.

A small gear box 20 is provided at the rear of the traveling vehicle body 1, and the rotation of the engine 3 is introduced through a transmission shaft 21.

A rod 23 extends upward from an arm 22 rotating at its rear end, and an arm 24 is made to swing, and the swing is converted into intermittent rotation by a ratchet (not shown) to rotate the delivery rotor 17. It is configured to do so. A transmission shaft 25 extends backward from the small gear box 20 and the gear box 11
The seedling stand 12 and the planting rod 14 are operated by this rotation.

A pair of left and right U-shaped mounting frames 26 are fixed to the traveling vehicle body 1 so as to protrude above the front axle 4. The lower end of the L-shaped support 28 is rotatably attached to a vertical shaft 27 provided at the horizontal end of this mounting frame 26. A plurality of tiers of spare seedling stands 29 are fixed to the L-shaped support 28 in the form of a trellis.

With the rotation of this L-shaped support 28 about the vertical axis 27.

The left and right spare seedling stands 29 are shown in the fertilizer tank 1 when viewed from the side.
It is configured to be located above 6 or to be located at the front part of the traveling vehicle body 1 by turning around from there. Note that a stop plate 3o with a notch is provided at the rotating portion of the L-shaped support 28, and a stop plate 3o with a notch is configured so that the claw that appears and retracts from the petal 31 engages with this to stop the movement.

During the seedling planting operation, the seedling planting machine configured as described above moves the preliminary seedling platform 29 to the front of the traveling vehicle body 1 as shown by the solid line in the figure.

That is, when the vehicle body 1 with the preliminary seedling platform 29 positioned at the front moves forward by rotating the front wheels 4 and rear axle 5 with the engine 3, the float 13 slides on the mud surface. do. In addition, the rotation of the engine 3 reaches the small gear box 20 via the transmission shaft 21, and then reaches the inside of the gear box 11 via the transmission shaft 25, moves the seedling platform 12 from side to side, and moves the tip of the planting rod 14 to the side. This planting rod 14 is rotated by an egg-shaped track groove when viewed visually.
takes out one seedling from the lower end of the seedling stand 12 and transplants it onto the mud surface leveled by the float 13.

At this time, the rod 23 moves up and down with the rotation of the arm 22, the arm 24 swings, and the feeding rotor 17 rotates intermittently. Then, the fertilizer in the fertilizer tank 16 is guided by the feeding rotor 17 via the hose 18 to the furrower 19, and is applied to the mud surface next to where the seedlings are to be transplanted.

As the work progresses in this manner, when the number of seedlings on the seedling platform 12 decreases, the forward movement of the traveling vehicle body 1 and the operation of the seedling planting device 6 and the fertilizing device 15 are stopped, the pedal 31 is stepped on, and the preliminary seedling platform 12 is stopped.
Bring 9 back. Then.

The L-shaped support 28 rotates around the vertical axis 27 to support the preliminary seedling stand 29.
reaches the top of the fertilizer tank 16.

Here, the operator moves the spare seedlings on the preliminary seedling platform 29 onto the seedling platform 12.

When the seedlings are replenished onto the seedling table 12 in this manner, the L-shaped support 28 is turned to return the preliminary seedling table 29 to its previous position, and the work is resumed.

When the fertilizer tank 16 runs out of fertilizer, the fertilizer is replenished to the spare seedling stand 29 with it positioned in front.
