DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing structure of a side fertilizer applied to a walking rice transplanter.

[0002]

2. Description of the Related Art A technique is known in which a side-strip fertilizer is mounted on a walking type rice transplanter and fertilizer is applied to the side streaks simultaneously with planting of seedlings. However, the conventional method of mounting the side-strip fertilizer applicator is such that the side surface of the feeding portion of the side-strip fertilizer is fixed to a fixing member, the fixing member is fixed to a support frame, and the support frame is a transmission of the rice transplanter. The structure was fixed to the case and the frame supporting the planting part, etc., and the working groove fixed to the fertilizer opening at the lower end was fixed to the lower part of the float arranged below the rice transplanter. .

[0003]

In the conventional method of mounting a side-strip fertilizer applicator, a fixing member requires an intermediate member such as a support frame, and the number of parts is increased. However, except for the part fixed to the float at the lower end, the frame structure was dispersed or avoided other members, so the rigidity was weak due to the presence of the intermediate member between the rice transplanter body and the side during work. The fertilizer applied rolled, and accurate fertilization could not be obtained.

[0004]

The present invention uses the following method to solve the above problems. That is, the lower part of the fertilizer application frame 1 which fixedly supports the feeding part of the side fertilizer is fixed to the lower frame connecting the mission case and the planting part, and the upper part of the fertilizer application frame 1 projects upward from the lower frame. This is fixed to the mounting frame.

Next, a configuration of the side-strip fertilizer applicator A and a configuration for mounting it on a walking rice transplanter will be described with reference to FIGS. The side-strip fertilizer applicator A is configured such that a fertilizing hose 4 is communicated with each lower portion of each feeding portion 3 and a hopper 2 is attached to an upper portion thereof. 4 is fixed to the rice transplanter main body by fertilizer application frames 1.1 arranged between the four. The fertilizer application frame 1 has a triangular shape in a side view, and as shown in FIG.
It is reinforced with. As shown in FIG. 2, the lower end fixing portion 1a of the fertilizer application frame 1 is fixed to the rice transplanter main body.
1b is fixed to the main body lower frame 5, and the upper end fixing portion 1c
Is fixed to a fertilizer mounting frame 5b projecting from the feed shaft support frame 5a erected on the main body lower frame 5 via a mounting member 6.
The lower part and the upper part are fixed to the frame of the main body, so that the integration with the rice transplanter main body is high, and the rigidity of the side-row fertilizer A and the whole rice transplanter is also increased.

[0010] The side-strip fertilizer applicator A feeds the granular fertilizer in the hopper 2 downward at the feeding section 3 and fertilizes it on a field through a fertilizing hose 4. The driving of the feeding section 3 will be described. Link 28a at the lower part of the planting claw 26
The link 7 is fixed so as to swing together with the
The lower part of the driving rod 8 is pivotally supported, and the upper end of the driving rod 8 is pivotally supported by a pivot shaft 9 a of the fertilizing amount adjusting member 9. The fertilizer application amount adjusting member 9 is fixedly mounted on one end of a rotation fulcrum shaft 10 that is laid horizontally above the fertilizer application frame 1. With the above-described configuration, the fertilization amount adjusting member 9 and the rotation fulcrum shaft 10 vertically rotate together with the rotation of the planting claws 26. The position of the pivot shaft 9a can be adjusted back and forth by an adjusting screw 9b, and the vertical rotation amount of the fertilization amount adjustment member 9 and the rotation fulcrum shaft 10 is adjusted by the positioning. A pivot 10a is protruded from the other end of the pivot shaft 10, and one end of the upper link 11 is connected to the pivot 10
a, and the other end of the upper link 11 is pivotally supported by a pivot 12a, and is extended via a one-way clutch 12 to a feeding portion 3 ·.
The rotation power is transmitted to a delivery drive pipe 13 provided horizontally between the three.

Here, the internal structure of the feeding section 3 (not shown) will be described. An upper hole 3a is opened in the upper part of the feeding section 3, and the granular fertilizer in the hopper 2 is filled with the hopper. 2 through the bottom holes 2a, 2a and the upper holes 3a, 3a. As shown in FIG. 3, an extension shaft 14 having an end fitted into the extension drive pipe 13 is provided in the extension portion 3 to link a vertical rotation axis via a bevel gear. A number of plates are arranged on the rotating shaft, a certain plate is in a state where the rotating shaft is loosely fitted, and a certain plate is fixed to the rotating shaft. Then, when the feed shaft 14 rotates and the vertical rotation shaft rotates, only the perforated plate fixed to the rotating shaft rotates, and the holes of the perforated plates coincide with each other intermittently. The fertilizer passes through the holes and falls into the fertilizing hose 4 below.

The distal end of the feed shaft 14 is fitted into the feed drive pipe 13 as described above, and the feed drive pipe 13 is rotated by the rotation of the upper link 11 connected to the turning fulcrum shaft 10. By rotating together with this, the unified feeding shaft 14 rotates. The adjustment in the fertilizer application amount adjusting member 9 adjusts the amount of rotation of the rotation fulcrum shaft 10 and the upper link 11 and the amount of rotation of the feeding drive pipe 13 and the feeding shaft 14. It controls the amount of rotation of the perforation and the amount of fertilizer that passes through the perforations in the perforation.

At the end of the feed shaft 14, a stop clutch 15 is provided. When the feed shaft 14 is fitted into the feed drive pipe 13, the stop clutch 1
5 is fitted with the feeding drive pipe 13. When the locking clutch lever 16 disposed on the outer side of each of the feeding portions 3 is rotated forward from the state shown in FIGS. 2 to 4, the base end of the locking clutch lever 16 formed in a cam shape. Pulls the sliding shaft 17, the locking clutch 15 slides toward the feeding portion 3 side, the fitting with the feeding drive pipe 13 is released, the transmission to the feeding shaft 14 is cut off, and fertilization in the feeding portion 3 is stopped. It stops. Conventionally, as an operation of the stop clutch, a knob was protruded directly behind the clutch, and the clutch was slid by operating the knob. Since the operation was difficult between the sections, the locking clutch lever 16 in this embodiment was difficult to operate.
In this case, the load of the lever operation is light, and the lever position is outside the feeding portion, so that the operation can be easily performed.

Next, the fertilizing hose 4 below the side-strip fertilizer applicator A
And the composition of a fertilization mouth part and a cropping part is explained. A groove 21 is fixed in front of the fertilization port 20, and the groove 21 is fixed to the lower surface of the float 23. And the fertilization mouth 20
A fertilizing hose 4 is interposed between the feeding section 3 and the feeding section 3.
Conventionally, the fertilizing hose is provided with a bellows-shaped boot at the upper part of the fertilizing mouth portion, and a tubular hose is interposed between the boot and the feeding portion. However, when a tubular hose is interposed, when the fertilizer absorbs moisture, it adheres to the inside of the hose and is easily clogged, and it is difficult to remove the fertilizer when it adheres. Therefore, as in the present embodiment, the bellows-shaped boot conventionally provided only at the upper part of the fertilizer application port is extended to the lower end of the feeding part to form the fertilizer hose 4,
The conventional tubular hose was eliminated. Thus, by eliminating the portion of the thin tubular hose, there is no adhesion of the hygroscopic fertilizer at the portion. The fertilizer can be dropped by expanding and contracting the hose 4.
