BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arrangement of a spraying cover of a medicine sprayer mounted on a rear part of a riding type rice transplanter.

[0002]

2. Description of the Related Art Conventionally, a technique for mounting a fertilizer applicator at the rear of a rice transplanter has been known. For example, actual Kaihei 2
This is like the technique described in US Pat.

[0003]

However, in the above-mentioned prior art, since no member for protecting anything is provided below and beside the spraying cover at the lower part of the medicine spraying machine, the planting and spraying is not performed. During the spraying operation or while moving on the road, the part of the spray cover projecting to the outermost side comes into contact with an obstacle and is damaged. The present invention has solved such disadvantages of the prior art.

[0004]

The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described. A chemical spraying device was installed at the end of the riding rice transplanter
, A spray cover 8 is arranged below the feeding device
Then, the front end of the spray cover 8 is placed on the rear end of the float of the rice transplanter.
And a bumper on both sides of the spray cover 8.
16 and the bumper 16 supports the spraying device C.
Extend from the support frame 5 to both left and right sides, and further
Fold it downward to cover the side of
And spread the rear lower end of the bumper 16
Spreading cover 8 arranged lower than the lower end of cover 8 by distance L2

DESCRIPTION OF THE PREFERRED EMBODIMENTS The problems to be solved by the present invention are as described above. Next, based on the configuration of the embodiment shown in the accompanying drawings,
The configuration of the present invention will be described. FIG. 1 is an overall side view of a medicine sprayer attached to a planting device of a riding type rice transplanter, and FIG. 2 is a rear view of the same. The planting device A is mounted from the traveling device of the riding type rice transplanter via the lifting device, and the planting device A
In the input case 1, power is input via a universal joint shaft from a PTO shaft protruding from the traveling device of the riding rice transplanter. Power is transmitted from the input case 1 to the planting mission case 2 arranged by the number of rows on the left and right, and the seedling mounting table 3 is inclined on the planting mission case 2,
A float 15 is provided below. At the rear of the planting mission case 2, a rotary planting claw 4 is arranged, a support frame 5 is erected from above the rear, and a side-strip fertilizer B is arranged at the front side of the support frame 5. Chemical sprayer C on rear side
Is arranged.

The medicine spraying machine C, which is a main part of the invention, has a hopper 7 mounted on a feeding case 6 and a spraying cover 8 provided below the feeding case 6. The driving of the feeding device provided in the feeding case 6 is performed by projecting a crank arm from a power take-out shaft 9 provided at a rear portion of the planted transmission case 2 and pivotally connecting a link 10 to the crank arm to reciprocate. The link 10 is pivotally connected to the turning arm 11 from the middle of the link 10 via a rod, and the reciprocating turning of the turning arm 11 is transmitted to the link 12, and the other end of the link 12 is pivotally supported by the adjusting arm 13. Have been. The base of the adjusting arm 13 is externally fitted to the drive shaft 14 via a one-way clutch, converts the reciprocating motion into an intermittent rotation motion, and extends from the drive shaft 14 to the pay-out shaft via a bevel gear disposed in the case 6. It is transmitting power.

A sprinkling cover 8 is provided laterally below the feeding case 6 in the width direction. A spinner 17 is provided at the center of the spreading cover 8, and the spinner 17 is provided with a blade on a disk to rotate at high speed. This causes the medicine or the like that has fallen on the blades to scatter in the left and right directions.
The center of 7 is fixed to the drive shaft of the motor provided on the extension of the extension shaft of the extension device. The spraying cover 8 is for restricting and guiding the scattering of the medicine.
As shown in the figure, the lower part of the spray cover 8 is formed in the shape of "" so that the medicine blown in the front-rear direction does not reach the float 15, and the front end of the spray cover 8 is separated from the rear end of the float 15 by a distance L1. It is arranged at the rear to avoid duplication.

Also, on both sides of the spray cover 8, the bumpers 1 are provided.
6, the bumper 16 extends from the rear end of the support frame 5 supporting the spraying device C to the left and right sides, and is further bent downward and rearward so as to cover the spraying cover 8, and the other end is moved rearward. The spray cover 8 is extended so as to protrude, and the rear lower end of the bumper 16 is disposed lower than the lower end of the spray cover 8 by a distance L2 to protect the spray cover 8. A support rod 19 is interposed between the front end of the bumper 16 and the planted transmission case 2 to reinforce the bumper 16.

[0009]

[Effect of the Invention] The present invention is constructed as described above, and has the following effects. First, the drug sprayer
Bumpers 16 are located below and beside the lower spreading cover.
Because it was placed, during planting / spraying work or moving on the street
When you are, the spraying cover is projected most outwardly way until
Eliminates the problem that the part hits an obstacle and gets damaged
I was able to do it. Second, the bumper 16
Remove the drug sprayer and place it on the ground or store it in the barn
In the case of
Ground the bar 8, feeding device and hopper on the ground.
Eliminates the need for cleaning and prevents rust on the sprayer
It is.
