Description

[Detailed Description of the Invention] This invention provides a structure in which a stripping body is provided on the lower surface of a land leveling sled body attached to the lower part of a rice transplanter, and fertilizer is applied into the groove created by the stripping body. This relates to a rice transplanter equipped with a fertilization device.In conventional devices of this type, fertilizer was applied in clusters directly below or to the side of the seedling planting position. As a result, as the planted seedlings grow, they hit the clumped fertilizer grains, damaging their roots, and the fertilizer is applied all at once, making the fertilizer ineffective over a long period of time. It is an object of the present invention to overcome these drawbacks and realize a rice transplanter equipped with a fertilization device that prevents the growth of seedlings from being inhibited and has a high fertilization effect.

For this reason, the present invention provides a land leveling sled body 13 for a rice transplanter.
The row body 16, which is buried in the soil to create the row groove A, is placed on the lower surface of the rice transplanter at a position slightly deviated laterally from the front-back direction line A of the seedling planting position B by the seedling planting device 7 of the rice transplanter. The rear side of the strip body 16 is provided on the left and right side plates 1.
In a fertilizer applicator that supplies fertilizer between the side plates in a shape in which the bottom between 6a and 16b is omitted, the bottom surface a of the row groove A created by the row member 16
The lower end of the side plate 16a on the other side of the cropping body 16 is lower than the lower end of the side plate 16b on the side of the seedling planting position B so that the height is higher on the side of the seedling planting position B and lower on the other side. This is a rice transplanter equipped with a fertilization device located at

This invention will be described in detail based on an embodiment shown in the drawings.

1 is the body of a rice transplanter, with a traveling transmission case 3 attached to the front and a seedling planting transmission case 4 attached to the rear. Reference numeral 2 denotes a prime mover, which is mounted on a mounting base attached to the front part of the traveling transmission case 3. Reference numeral 5 denotes a chain case, which has drive shafts protruding from both left and right sides of the traveling transmission case 3, and is freely rotatable around the drive shafts, and a paddy wheel 6 is mounted on the shaft so as to be rotated by transmission to the tip side of the chain case. It has been done.

Reference numeral 7 denotes a seedling planting device, which is attached to both left and right sides of the seedling planting transmission case 4, and a seedling dividing engagement claw 8 attached to the tip of the seedling planting rod moves up and down to form an oval shape. It is set up so as to draw a circular trajectory.

Reference numeral 9 denotes a control handle, the base of which is fixed to the rear surface of the transmission case 4 for planting seedlings, the tip of which extends rearward and upward, and a grasping portion is provided at the tip to which a clutch lever or the like is attached.

Reference numeral 10 denotes a seedling tank, which is disposed above the control handle 9 and supported so as to be movable left and right, and is moved to a left and right reciprocating mechanism consisting of a lead cam and a lead metal etc. provided in the seedling planting mission case 4. stick 1
1. It is connected via an operating plate 12 and is configured to supply seedlings one plant at a time to the seedling planting device 7.

Reference numeral 13 denotes a ground leveling sled body, which is provided at the lower part of the rice transplanting machine body 1, and whose rear part is pivotally connected to the lateral pin 14.
The front part is attached with a link 15 that can be expanded and contracted up and down,
It is designed to move up and down.

Reference numeral 16 denotes a striping body, and in the illustrated example, as shown in FIG.
It is composed only of 6b, and the top plate and bottom plate are omitted. And side plates 16a, 1 of this strip body 16
6b has different lengths in the vertical direction and is attached to the lower surface of the ground leveling sled body 13 as follows.

That is, the seedling planting device 7 is attached to the bottom of the soil leveling sled body 13 slightly off from the front-rear direction line A of the seedling planting position (B) where seedlings are planted at the leveling position of the soil leveling sled body 13, The vertical dimension of the side plate 16a corresponding to the seedling planting position B side of the sled body 16 is short, and the vertical dimension of the opposite side is long.
The bottom surface a of the groove A created when the
The soil is arranged in a diagonal shape, with the side where the seedlings are planted being higher and the other side being lower.

Reference numeral 17 denotes hoppers of a fertilizer application device, which are arranged in parallel in the left and right direction and are provided above the rice transplanting machine corresponding to the number of seedling planting rows.At the bottom of this hopper 17, a fertilization delivery roll 20 is driven and rotated. The hose 18 is arranged so that the fertilizer fed out is guided between the left and right side plates 16a and 16b of the strip body 16.

In addition, in the figure, 19 is a chain case that covers the chain that drives the fertilization delivery roll 20, 21 is a delivery roll shaft, 22, 23 is a stay that fixes the hopper 17, and 24 is a notch in the ground leveling sled body 13. .

In the configuration of the above example, after seedlings are placed in the seedling tank 10 and each hopper 17 is filled with solid fertilizer, each rotating part is driven to rotate by the prime mover 2.

Then, the rice transplanter is propelled by the left and right paddy wheels 6, 6, the surface of the paddy field is leveled by the lower leveling sled body 13, and the rowing groove A is created on the surface of the paddy field by the rowing body 16. . The fertilizer in the hopper 17 is fed out by the feeding roll 20, guided by the hose 18, and supplied into the cropping groove A, but at this time, the bottom surface a of the cropping groove A becomes oblique in the left-right direction. Therefore, the fertilizer supplied will be applied along this slope and will be buried and maintained in that state with mud.

At the rear of the fertilized area near the high bottom side of the cropping furrow A, the seedling planting device 7 separates and plants one seedling at a time from the seedling tank 10 which is reciprocated from side to side. It will be done.

In this way, the seedlings are planted to the side of the fertilization position,
As the seedlings gradually grow, the roots of the seedlings extend downward toward the periphery. At this time, since the fertilizer is applied in the direction in which the seedlings grow, the concentration of fertilizer is not locally high and root damage does not occur, and moreover, it is effective over a long period of time, increasing the effect of fertilization. I can do it.

Since this invention has the above-mentioned structure, it is possible to apply fertilizer to the sides of the seedlings to be planted with a rice transplanter so that the fertilizer does not form in clumps and to become deeper as the distance from the seedlings increases. The fertilizer can be applied over a long period of time without damaging the roots, and has the effect of increasing the effect of fertilization.
