Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arrangement structure of fertilizer hoses in a riding rice transplanter in which a main body of a fertilizer applicator is arranged on a traveling section side.

[0002]

2. Description of the Related Art Conventionally, in a planting section of a rice transplanter, a lateral feed mechanism that adjusts the seedling planting speed by shifting the sliding speed of the seedling table in the left-right direction, and a single planting claw. In order to adjust the number of planted seedlings by adjusting the number of seedlings to be sandwiched, the vertical feed mechanism that adjusts the vertical feed amount of seedlings by changing the distance between the seedling mounting table and the planting claw They were provided on both sides of the mission case.

On the other hand, when a fertilizer applicator is attached to the rice transplanter, the front-rear balance of the machine is disturbed and the running performance and the posture of planting the seedlings are deteriorated. I want to arrange it. However, the above-mentioned planting mission case on the back side of the seedling mounting table and the parts of the horizontal feed mechanism and the vertical feed mechanism on both sides of it are too narrow to pass the fertilizer application hose of the fertilizer applicator. In that case, it is necessary to bend the hose, which results in a hose shape that is not smooth with respect to the flow of the fertilizer, which causes clogging of the fertilizer, and it is difficult to reliably spread the fertilizer. Therefore, the drive shaft of the vertical feed mechanism is extended in the left-right direction, and the vertical feed movable parts are provided at two locations on both ends of the seedling mount, or the shape of the planted mission case is viewed in plan. The fertilizer application hose is formed in a U shape or a U shape so that the fertilizer application hose can be passed through the recesses with a small amount of bending to secure a piping space for the fertilizer application hose.

[0004]

However, in the above-mentioned prior art, in the structure in which the vertical feed movable parts are arranged at two positions on both ends of the seedling placing table, the drive shaft becomes long and the vertical feed movable parts are formed. Since two parts are required, the weight and cost increase, and it is not possible to reduce the weight and size of the planting part. In addition, if the planted mission case is shaped like a letter U or a letter U in plan view, the power transmission structure will be complicated and the planting part cannot be simplified, and maintenance will be performed easily. I can't. Therefore, the present invention aims to reduce the weight and size of the planting section and to simplify the planting section.When the main body of the fertilizer applicator is disposed on the traveling section side, the fertilizer hose can be easily piped to ensure the fertilizer. The purpose is to construct a riding rice transplanter that secures a space around the planting section so that it can be supplied to the plant.

[0005]

The present invention uses the following means in order to solve the above problems. That is,
In the riding rice transplanter where the main body of the fertilizer applicator is located on the running side and the fertilizing hose is piped on the side of the planting transmission case where the planting claws of the planting section are installed, the transverse feed mechanism of the seedling table can be moved. Section and the movable part of the vertical feed mechanism are arranged between the fertilization hoses with the widest spacing and the fertilization hoses, and are configured to move laterally between the fertilization hoses and the fertilization hoses. The thickness of the left and right widths is made thin to form a space through which the fertilizing hose passes on the side of the planted mission case, and the fertilizing hose is composed of a flexible hose, a fixed hose, and a boot, which are connected in order from the main body side. In the connection part of
It is slightly bent to one side in a front view and slightly bent to an oblique front side in a side view.

[0006]

[Function] With this structure, the fertilizer application hose of the fertilizer applicator can be passed through without interfering with the surroundings of the planting mission case of the planting section, and piping should be provided so that the flow of fertilizer is smooth. You can Further, since the tip end side of the fertilizer application hose is bent in a range as small as possible,
It is possible to prevent the fertilization hose from being stretched or loosened due to being affected by the elevation of the planting part.

[0028]

Since the present invention is configured as described above, it has the following effects. That is, by constructing the lateral feeding movable part and the vertical feeding movable part of the seedling mounting table at the widest pitch of the fertilizer application hose of the fertilizer applying device, the lateral feeding mechanism and the vertical feeding mechanism of the seedling mounting table can be arranged on one side of the machine body. Since they can be arranged in a concentrated manner, the size of the planting part can be reduced, and the adjustment and maintenance of the lateral feed mechanism and the vertical feed mechanism can be easily performed.

By piping the fertilizer application hose through the side of the planting mission case, the fertilizer can be piped so that the flow of fertilizer can be made smooth without being affected by surrounding obstacles. Fertilization hoses can be easily piped to ensure reliable supply. Also, by bending the tip side of the fertilizer hose within a range as small as possible, it is possible to smooth the flow of fertilizer and prevent the fertilizer hose from being stretched or loosened due to being affected by the elevation of the planting part. Therefore, it is possible to prevent the fertilizer application hose from being pulled and damaged or detached, and to prevent the fertilizer from clogging due to slack.
