DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter equipped with a fertilizer and a fertilizer, which is configured to feed a fertilizer into a field as a seedling is planted.

[0002]

2. Description of the Related Art In a rice transplanter with a fertilizer device as described above, a fertilizer device is fixed at a predetermined position, and the predetermined position is set as a work position of the fertilizer device for feeding fertilizer into a field, and fixed at the work position. Many fertilizers are configured to send fertilizer to a field from the fertilizer application devices.

[0003]

In the rice transplanter with a fertilizer device as described above, the fertilizer device is often located close to the working position of the fertilizer device. It may be difficult to perform maintenance work on other devices. An object of the present invention is to make it possible to easily perform maintenance work on a fertilizer application device and other devices nearby in a rice transplanter with a fertilizer application device.

[0004]

A feature of the present invention is that a rice transplanter with a fertilizer is configured as follows. A fertilizer that feeds the fertilizer into the field with the planting of the seedlings; a work position ranging from a lower working position for feeding the fertilizer to the field and a non-working position that is separated upward from the working position; In addition to a supporting mechanism movably supported via a guide member in a state where the posture is maintained, a biasing mechanism for lifting and biasing the fertilizer application device to the non-working position side is provided. It is located on the left and right center sides of both lateral ends.

[0005]

According to the first aspect of the present invention, the fertilizer applicator located at the working position can be moved to the non-working position remote from the working position via the guide member. Thereby, by separating the fertilizer application device from the working position to the non-working position, without being disturbed by other devices arranged near the working position,
Maintenance work of the fertilizer application device can be easily performed. Maintenance work of other devices arranged near the work position can also be easily performed without disturbing the fertilizer application device.

When the fertilizer is moved between the working position and the non-working position, the fertilizer can be moved via the guide member while maintaining the posture in the working position. When moving the fertilizer, the fertilizer in the fertilizer application device does not spill out, and it is not necessary to take out the fertilizer from the fertilizer device for the transfer operation.

[II] According to the first aspect of the present invention, the fertilizer can be moved up and down between the lower working position and the upper non-working position. The fertilizer does not protrude largely in the lateral direction from the rice transplanter. Accordingly, even in a relatively narrow place such as a barn, the fertilizer application device can be moved to the upper non-working position without any trouble.

[0008] In addition to a guide member for movably supporting the fertilizer application device between the working position and the non-working position, an urging mechanism for lifting and urging the fertilizer device toward the non-working position is provided. With the assistance of the urging mechanism at the time of the moving operation, the fertilizer applicator can be easily moved to the non-working position.

[III] If the guide member and the urging mechanism for movably supporting the fertilizer applicator between the working position and the non-working position are arranged at both left and right lateral ends of the fertilizer applicator, the vehicle can travel on the road. There is a possibility that the guide member and the urging mechanism may be hit against other obstacles when the vehicle turns, and the guide member and the urging mechanism may be damaged. According to the feature of the first aspect, since the guide member and the urging mechanism are arranged on the left and right central sides of the left and right lateral ends of the fertilizer application device, the guide member and the urging mechanism are used when turning on a road or the like. There is no such thing as breaking the mechanism by hitting other obstacles.

[0010]

According to the first aspect of the present invention, in a rice transplanter with a fertilizer device, the fertilizer device is configured to be movable to a non-work position away from the work position, thereby being disposed near the fertilizer device and the work position. This makes it possible to easily carry out maintenance work on other devices, and to improve the workability of the rice transplanter with the fertilizer application device. When the fertilizer is moved between the working position and the non-working position, the fertilizer in the fertilizer does not spill out, so there is no need to remove the fertilizer from the fertilizer for the moving operation. There is no waste of fertilizer, and the generation of rust and the like due to the fallen fertilizer adhering to the metal part is also prevented.

The fertilizer can be moved up and down between a lower working position and an upper non-working position, so that the fertilizing device can be moved to the non-working position even in a relatively narrow place such as a barn. The workability of the rice transplanter with the fertilizer applicator can be further improved. Providing the urging mechanism for lifting and applying the fertilizer application device to the non-working position side allows the fertilizer application device to be easily moved to the non-working position, thereby improving operability.

A guide member and a biasing mechanism for movably supporting the fertilizer application device between a working position and a non-working position are disposed at the left and right central sides of the left and right lateral ends of the fertilizer application device. And the urging mechanism is not hit against other obstacles and is damaged, so that the guide member and the urging mechanism are not damaged, and the moving operation of the fertilizer device is not hindered. The smooth movement operation of the fertilizer application device can be performed.

In the state shown in FIG. 3B, when the seedling planting device A is set at the lowest position with respect to the traveling machine together with the link mechanism (not shown), the seedling placing surface b, the fertilizer storage hopper 8, and the feeding mechanism The interval between the seedling 9 and the seedling 9 is greatly widened, so that the seedling remaining on the seedling placing surface b can be easily treated.

[Another Embodiment] Not only the fertilizer storage hopper 8 and the feeding mechanism 9 but also the downflow pipe 10 and the groove generator 11 are integrally formed so that the entire fertilizer applicator B can be moved up and down. You may comprise. As a mode of moving the fertilizer storage hopper 8 and the feeding mechanism 9 in the vertical direction, a link (not shown) (corresponding to a guide member) may be used instead of the guide column 12. As a mode of providing the stand 23, only when the stand 23 is attached to the storage portion of the riding type traveling body and the manure storage hopper 8 and the feeding mechanism 9 are moved to the upper non-working position and fixed. 23 is removed from the storage part, and the stand 2 is placed between the bracket 24 and the ground.
3 may be used. In this case, the stand 23 may be of a fixed size instead of a telescopic type. A configuration in which the feeding mechanism 9 is driven by a dedicated motor (not shown) may be adopted. When this motor is attached to the feeding mechanism 9, a separation device such as a turnbuckle-type connecting tool 22 is not required. As the fertilizer applicator B, in addition to the side-strip type fertilizer applicator B shown in the drawings, a deep-layer type fertilizer applicator B and a lateral-strip deep-layer fertilizer applicator B, or a fertilizer applicator B and a fertilizer spraying apparatus may be arranged in parallel. The stand 23 may be extended by air pressure and contracted when the air pressure is released. In this case, a configuration may be adopted in which a foot-operated air pump is used as the air pressure supply means, and the plug is loosened to release the air pressure. The fertilizer applicator B may be located on the back side of the seedling rest 1. The present invention may be applied to a walking type rice transplanter equipped with the fertilizer application device B.
