Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention provides a seedling planting device on one end side of a traveling machine body, and applies fertilizer so as to face the seedling placement surface of a seedling stand of the seedling planting device. The present invention relates to a paddy work machine in which a device is provided.

[Conventional technology]

Taking rice transplanters as an example of paddy work machines, recently commercialized rice transplanters use a seedling planting device to send fertilizer to the field near the seedling planting position simultaneously with the seedling planting operation. Is provided with a fertilizer application device, and the fertilizer application device has the same number of groovers as the number of planting lines of the seedling, and
A hopper for supplying fertilizer to each of the plurality of groovers and the like is also provided (for example, Japanese Utility Model Laid-Open No. 61-204426).

[Problems to be Solved by the Invention]

As described above, in the case where the hopper is provided for the seedling planting device, since the plurality of hoppers are arranged along the lateral direction of the machine, when supplying the fertilizer to the hopper, Even when stopped at the edge of the ridge, the worker had to enter the field and supply fertilizer to the hopper from a position such as behind the seedling planting device, which was annoying.

Also, if the planting claw does not bite a small stone, or
When there is no seedling, when checking whether the sliding contact surface of the seedling stand slide rail is damaged by pebbles etc., those near both sides can be inspected from the side, but those near the center Has the inconvenience that it is difficult to inspect.

An object of the present invention is to make it possible to supply fertilizer to the hopper from a lateral side position of the aircraft even if the hopper is arranged along the lateral direction of the aircraft by reasonable modification. In addition to the above, the paddy field work machine that allows easy inspection around the center of the seedling planting device is configured.

[Means for Solving the Problems]

A feature of the present invention is that the hopper of the fertilizer application device is provided with a guide mechanism so that the hopper of the fertilizer application device can be laterally outwardly projected and moved with respect to the seedling planting device. .

[Action]

If the above features are configured as shown in FIG. 1, for example, when supplying fertilizer to the hopper (16), the hopper
By projecting and moving (16) laterally outward as shown in FIGS. 1 and 2, the operator does not need to approach the position behind the machine body (3) or the like, and as shown in FIG. Aircraft (3) ridge (C)
When approaching the ridge, the ridge (C) does not enter the field (P).
Can be supplied from.

When the hopper (16) is laterally outwardly projected and moved as shown in FIGS. 1 and 2, a space is formed which makes it easy to look into the planting portion near the center of the machine from above.

〔The invention's effect〕

Therefore, by a modification such as providing a guide mechanism,
Even if the hopper was arranged along the lateral direction of the machine body, a paddy work machine was configured that could supply fertilizer to the hopper from the lateral side position of the machine body.

Also, when checking whether the planting claws are not biting pebbles, etc., or when the seedling stand slide rail sliding contact surface is not damaged by pebbles when there is no seedling, the fertilizer application By moving the hopper laterally outward with respect to the seedling planting device, the planting portion near the center of the aircraft, which is difficult to inspect, can be looked into from behind the aircraft and easily inspected.

〔Example〕

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

As shown in FIG. 4, the engine (4) and the transmission case (5) are arranged in front of the traveling machine body (3) having the front and rear wheels (1), (2).
A steering handle (6) and a driver's seat (7) are arranged in the approximate center, and seedlings are planted at the rear end of the machine body (3) via a link mechanism (9) that moves up and down by the operation of a hydraulic cylinder (8). The device (A) is connected to form a rice transplanter as an example of a paddy field working machine.

As shown in the figure, the seedling planting device (A) has a transmission case (10).
And a pair of chain cases (11), (11) and a planting claw at the tip.
(12a) equipped with four planting arms (12) ... and seedling stand (1) that reciprocates left and right along the seedling stand slide rail (13a).
3) and three leveling floats (14) ... are configured for 4 rows, and this seedling planting device (A) supplies fertilizer to the field at the same time as the seedling planting operation. It is equipped with a fertilizer applicator (B).

As shown in FIGS. 1 to 3, the fertilizer application device (B) is
5) ... is provided with a hopper (16), a feeding mechanism (17), a hose (18) and a grooving device (19), and the feeding mechanism (1
The drive shaft (2) to which the feeding roll (17a) built in 7) is fitted
On the other hand, the rocking driving force from the planting arm (12) is transmitted via the rod (21) to the fertilizing operation in synchronization with the seedling planting operation. .

In addition, in order to keep the amount of fertilizer delivered constant,
Brushes (22), (22) are provided in contact with 7a), and as shown in FIG.
It is composed of a), a slide member (22b), and a flocked portion (22c) in which a gap is formed in the lateral direction.

Also, in this rice transplanter, as shown in Figs.
In a state where (3) is brought close to the ridge (C) and stopped, a worker does not enter the field (P), and from the position of the ridge (C), the hopper
A guide mechanism (D) for laterally outwardly projecting the hopper (16) is provided so that fertilizer can be supplied to the (16).

That is, the guide mechanism (D) includes a guide rail (23) fixed on the fertilizer application side (B), a support rail (24) fixed on the hopper (16) side, and a guide rail (23). ) And a slide rail (25) slidable with respect to each of the support rails (24), and a shutter (27 ) Is provided, and also
