[Problems to be solved by the device]

 In addition, the recently developed rice transplanter is equipped with two planting arms in a case that rotates around a horizontal axis, and two seedlings are planted in one rotation operation of this case to achieve high-speed seedling. There are some that made planting possible. However, when the case and the planting arm rotate in this way, the water content in the field can be easily splashed upward when the seedling planting operation is performed. In a rice transplanter configured to have a storage part and a feeding part, etc., not only does muddy water adhere to the storage part and the feeding part to cause stains, but also rust and drive shafts and feeding parts of the feeding part. There is room for improvement because it may cause the fertilizer to be moistened by the intrusion of water through the gap between the casing and the casing, causing clogging of the fertilizer supply system. An object of the present invention is to provide a seedling planting machine in which a fertilizer supply mechanism such as a storage section and a feeding section is arranged above a seedling planting mechanism in which a plurality of planting arms are provided in a case that rotates on a lateral axis. The point is to obtain a structure in which the water in the field that has been splashed up by the planting mechanism does not adversely affect the fertilizer supply mechanism.

[Technical field to which the device belongs]

 The present invention relates to a rice transplanter, and more particularly to a rice transplanter provided with a fertilizer application device for supplying fertilizer to a field near a seedling planting position at the same time as seedling planting work.

[0002]

[Prior art]

 Conventionally, as a rice transplanter equipped with a fertilizer application as described above, there is a rice transplanter disclosed in Japanese Utility Model Publication No. 61-182221, and such a rice transplanter equipped with a fertilizer application has a seedling planting position. In order to supply fertilizer to the field near the plant almost at the same time as the seedling planting time, the fertilizer storage part is located above the planted nail case and the storage part is powered by the drive system of the planted nail case. Generally, a feeding section for feeding fertilizer from the feeding section is arranged, and a hose or the like for feeding the fertilizer from the feeding section to the vicinity of the seedling planting position in the shortest distance is generally provided. Also, in recent years, as a seedling planting mechanism that enables highly efficient planting, a pair of planting arms are provided in a rotary case that rotates around a horizontal axis so that two rotations can be planted with one rotation of the rotary case. A rice transplanter which has been developed and equipped with a fertilizer application device of such a model is known, for example, as disclosed in Japanese Patent Laid-Open No. 62-96007.

[0003]

[Problems to be solved by the device]

 As described above, a new type of seedling planting mechanism in which the rotary case and the planting nail case attached to the rotary case rotate makes it possible to perform planting by cranking one planting nail case. Compared with the traditional seedling planting mechanism that is used, it is useful in that the planting speed can be significantly increased, but on the other hand, it also has the following disadvantages. In other words, the planting claw case with the planting claws that actually divides the seedlings is attached to the fixed planting case that incorporates the power transmission mechanism via the rotary case that rotates. If you try to avoid both the rotary case and the planting case and position the fertilizer hose laterally, the fertilizer hose itself will be considerably separated from the position of the planting claw. Therefore, it tends to be difficult to set the distance between the planted seedling position and the lateral row fertilizer position to a preferable distance. Also, if you try to install the fertilizer hose on the side opposite to the rotary case with the planting claw case sandwiched, it will be difficult to fix the position unless the fertilizer hose is made of a material with high rigidity. However, if the rigidity is increased, it is not preferable in any case that the structure for linking the end of the fertilizing hose with the floating float that is linked to the fertilizing hose end becomes complicated. An object of the present invention is to arrange a fertilizer supply mechanism, such as a storage section and a feeding section, above a seedling planting mechanism in which a plurality of planting claw cases are provided in a rotary case that rotates on a horizontal axis. In the machine, it is easy to perform fertilization by appropriately setting the positional relationship with the seedlings to be planted by the seedling planting mechanism, and to arrange the fertilizer hose compactly while avoiding interference with the seedling planting mechanism.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the characteristic structure of the present invention is that a rotary case that is driven and rotated around a lateral axis is provided at a side position of a planting case that houses a power transmission mechanism. The seedling planting mechanism is configured by providing a planting nail case equipped with planting nails for splitting seedlings, and a fertilizer storage section for fertilization arranged above the seedling planting mechanism and a storage section. In the rice transplanter provided with a fertilizer supply mechanism having a feeding section for feeding the fertilizer, the fertilizer hose for guiding the fertilizer fed from the feeding section to the fertilization target position is provided. It is located near the outer track of the rotary case that is driven and rotated around the core, and is located outside the outer track to support the hose support so as to prevent contact with the rotary case. . As the hose support, one that supports the fertilizer hose in both the radial direction with respect to the rotary case and the lateral direction of the machine body may be used. The hose support may be configured to support a pair of left and right fertilizer application hoses.

[Operation] The operation of the above characteristic configuration is as follows. a. That is, since the hose support body is provided near the outer peripheral track of the rotary case to be driven and rotated and located outside the outer peripheral track to support the rotary case so as to prevent contact with the rotary case. It is possible to support the fertilizer application hose from the planting claw case without greatly separating it from the planting claw case while reliably avoiding contact with each other, so that the relative positional relationship between the seedling planting site and the fertilizing site can be set appropriately. It is easy to install fertilizer hoses. b. As described in claim 2, in the structure in which the hose support body supports the fertilization hose so as to regulate the position in both the radial direction and the machine left-right direction with respect to the rotary case, the fertilization hose position can be further accurately measured. Can be regulated. c. As described in claim 3, when the hose support body supports a pair of left and right fertilizer application hoses, the mounting structure of the hose support body can be simplified.

[Effect] a. Above a. Therefore, in a rice transplanter that employs a seedling planting mechanism in which a rotary case that rotates on a horizontal axis has multiple planting claw cases, the positional relationship with the seedlings planted by the seedling planting mechanism is properly determined. Fertilization can be performed easily, and the fertilization hose can be arranged compactly while avoiding interference with the seedling planting mechanism. B. Above b. By this action, the support position of the fertilizer hose can be maintained with higher accuracy. C. Above c. From the above effect, the hose support mounting structure can be simplified.
