DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of planting plants for taking out and planting seedlings from the lower end of a seedling rest in a seedling planting device, respectively, on a lateral side of a plurality of transmission cases in which a transmission mechanism is installed. In addition to disposing the mechanisms, the same number of fertilizer feeding mechanisms as the above-described planting mechanisms are mounted above these planting mechanisms, and the interlocking linkage is performed by changing the rotating phases of the rotating parts of the planting mechanisms to each other. Via a pair of left and right push-pull linkage members
The fertilizer feeding roll of the feeding mechanism is configured to rotate in a fixed direction, and an odd number of the planting mechanisms are provided, and one of the transmission cases is used to set one planting mechanism. , And the other transmission cases each relate to a rice transplanter with a fertilizer device, which is configured to drive a planting mechanism two by two.

[0002]

2. Description of the Related Art Conventionally, in a rice transplanter with a fertilizer applicator, conventionally, a feeding roll of a fertilizer feeding mechanism corresponding to the one planting mechanism is driven by two rolls, which are located on either side of the left or right side thereof. A configuration has been considered in which the interlocking and linking is performed so as to rotate integrally with a feeding roll of a feeding mechanism corresponding to the planting mechanism to be used. Incidentally, as a configuration in which a pair of right and left push-pull linking members are linked to each other with different rotation phases, for example, as shown in FIG. Linking the linking member to each planting mechanism, with the continuous rotation drive of the planting mechanism,
There is a structure in which the feeding roll is also continuously driven to rotate in a predetermined direction so as to continuously and smoothly feed the fertilizer.

[0003]

As an example of the odd-row planting format, for example, in the case of five-row planting, planting is carried out on the left and right sides of each of the three transmission cases located on the left and right sides. The transmission case located at the center is provided with one planting mechanism only on one side, and is configured in a five-row planting format. Each of the feeding mechanisms is configured to rotate integrally, and can be linked to two corresponding planting mechanisms via a pair of linking members, respectively. The central feeding mechanism is one planting mechanism. Since there is only a drive system,
In the above-mentioned conventional structure, it is designed to rotate integrally with one of the left and right feeding mechanisms. However, the conventional structure has the following disadvantages. In other words, when partial planting is performed in which only part of the planting work is planted on all the planting works, even if the power of each of the transmission mechanisms in the transmission case is intermittently connected, the feeding mechanism located at the center is Since it always operates integrally with the feeding mechanism on either the left or right side, the feeding mechanism cannot be turned on and off independently. It becomes impossible to use properly. An object of the present invention is to eliminate the above disadvantages.

[0004]

According to a feature of the present invention, in a rice transplanter with a fertilizer device described at the beginning, each of a pair of planting mechanisms driven by one of the transmission cases, respectively. The push / pull linking members for the feeding mechanism corresponding to the planting mechanism are interlocked and linked, and the transmission case that drives the one planting mechanism is mounted on the side opposite to the side where the planting mechanism is provided. An eccentric drive mechanism driven by a rotation mechanism driving shaft is provided, and one of the push-pull linkage members linked to and linked to the one planting mechanism has a different rotational phase from each other, and the other push-pull linkage member has the other push-pull linkage mechanism. The pulling linking member is linked to the eccentric driving mechanism to link and drive the fertilizer driving roll of the feeding mechanism for the planting mechanism in a fixed direction.

[0005]

In an odd number of feeding mechanisms, at a place where one planting mechanism and one fertilizer feeding mechanism correspond to one transmission case, the planting is performed on the fertilizer feeding mechanism. A single push-pull link member linked to the mechanism and another push-pull link member linked to the eccentric drive mechanism provided on the opposite side of the transmission case are linked and linked, so that the feeding roll can be smoothly moved. It is possible to perform a continuous rotation operation capable of feeding out the fertilizer and to intermittently turn on and off the power of the transmission mechanism in the transmission case, so that the operation of the feeding mechanism can be arbitrarily turned on and off.

[0006]

Therefore, the planting mechanism and the fertilizer feeding mechanism driven by the transmission mechanism provided in each transmission case can be arbitrarily selected to be in the drive-on / off state, and the fertilization in the partial-row planting operation can be performed. It has become possible to provide a rice transplanter in which the number of work steps can be set to an appropriate desired state.
