Abstract

PROBLEM TO BE SOLVED: To provide the subject method intended to transmit mechanical power from a working machined free from any mechanism to access power by setting up e.g. a fertilizer applicator at a specific site on the working machine to transmit mechanical power from the working machine via a spring to the above applicator. SOLUTION: This method comprises setting up e.g. a fertilizer applicator on the rear portion of a working machine free from any power withdrawal mechanism and transmitting mechanical power from the working machine via a spring to the above applicator; wherein, for example, a frame 2 is constructed under a steering seat 1 on the rear portion of the working machine, a spring 5 is connected from a rear wheel 3 via a spring fixture 4 to the frame 2, one end of the spring 4 is linked to one end of a primary rotating shaft 7, the central part of the rotating shaft 7 is mounted with a sprocket 8; besides, a secondary rotating shaft 9 is set up on one side of the frame 2, the central part of the secondary rotating shaft 9 is mounted with a 2nd sprocket 8, these two sprockets 8 are connected to each other through a chain 11, and a crutch 10 is attached adjacently to the sprocket 8 on the secondary rotating shaft 9.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to the cultivation of agricultural crops.

[0002]

2. Description of the Related Art There are various methods for dispersing fertilizers and the like using a power working machine, and all of them have a mechanism for performing the work for a work purpose.

[0003]

In order to prevent the emergence of paddy field weeds without using a herbicide, the present inventor has proposed, as disclosed in Japanese Patent Application Laid-Open No. Hei 10-52209, a simultaneous application with rice planting. Or, immediately after planting, it is necessary to spray a large amount of material on the paddy field.

[0004] At present, a rice transplanter having a function for achieving the above-mentioned object has not been manufactured, and a power take-out mechanism for enabling the work has not been provided.
It is necessary to develop a new power transmission method.

[0005]

Since there is no power take-out mechanism, it is necessary to use one of the rotating parts of the working machine, and the rear wheel is an example of this.

As a means for extracting power from the rear wheels, a sprocket and a pulley can be attached to the wheels, and the power can be transmitted by a chain or a belt.

[0007] According to the preceding paragraph, the chain or belt attached to the wheel is not practical because the chain is detached or the belt slips due to the earth and sand lifted by the working wheel.

[0008] In the case of power transmission by a spring, there is no relation to the obstacle described in the preceding paragraph.

[0009]

The transmission of power by the spring is limited to work with a relatively small load.

In the case of power transmission by a spring,
Since the rotation speed cannot be adjusted like sprockets and pulleys, primary and secondary rotation shafts are installed on the fertilizer application side, large and small sprockets and pulleys are attached to both, and the rotation speed is adjusted via chains and belts I do.

Embodiments will be described with reference to the drawings.
In FIG. 1, a gantry 2 is constructed from a floor portion below a cab 1 at the rear of the working machine. Rear wheel 3 to spring mounting part 4
, And one end of the spring 5 is connected to one end of a primary rotation shaft 7 attached to the gantry 2 via a bearing 6. Sprocket 8 at the center of primary rotating shaft 7
Attach. Also, a secondary rotating shaft 9 is installed on one side of the gantry 2, and a sprocket 8 is
Next, the sprockets 8 of the secondary and secondary shafts are connected by a chain 11. Then, the clutch 10 is mounted adjacent to the sprocket 8 of the secondary rotating shaft 9. Also, sprocket 8
Then, the drum 12 is attached to the shaft with the clutch 10 interposed therebetween. The drum 12 is provided with several grooves 13 for spraying fertilizer and the like.

In the embodiment shown in FIG. 2, a hopper 14 for accommodating materials such as fertilizer is installed so as to straddle the drum 12 attached to the secondary rotating shaft 9 on the gantry 2.

In the embodiment shown in FIG. 3, a clutch lever 15 is mounted on the head of a clutch 10 mounted on the central portion of the secondary rotating shaft 9, so that the clutch lever 15 can be easily operated from the cab 1. I have.

The embodiment shown in FIG. 4 is a detailed view of the spring mount 4 shown in FIG. Several bolts 23 are passed through the plate 22 of the rear wheel axle mounted on the drive shaft 21, and a spacing pipe 24 is fitted into each of the bolts 23. Meanwhile, iron plate 2
7 is welded 29 to a shaft 28 for connecting the spring 25. A hole having the same diameter and the same interval as the axle plate 22 is formed in the welded plate 27, and is fixed via a nut 30. One side of the pipe 31 that fits the inside diameter of the spring 25 is inserted into the inside of the spring 25 and fixed by the band 32. One of the pipes 31 overlaps a shaft 28 welded to the plate 27 and is fixed with bolts 33.
One of the springs 25 is connected to the primary rotation shaft 26 by the above-described method.
Connect to

In the embodiment shown in FIG.
A hopper 43 framed by an angle 42 is attached to the hopper 43. The rotation of the secondary rotation shaft 44 is
5 also rotates, and accordingly, materials such as fertilizer in the hopper 43 are supplied from the drop port 46 to the grooves 47 of the drum 45.
Penetrates and is continuously sprayed on the rice fields.

[0016]

Since the present invention is configured as described above, it has the following effects.

Power can be transmitted from a working machine without a power take-out mechanism.

It is possible to cope with work under poor conditions without any trouble.

It can be applied to both solid and powder form materials.

The application range is large, from small to large.
