Description

[Detailed Description of the Invention] The present invention relates to a tilling device for the side row fertilization section of a rice transplanter.

That is, in a rice transplanter configured by installing a groove-making body on the side of the float that is lateral to the planted seedlings, the groove-making body can make grooves on the rice field and apply fertilizer in the grooves. The soil plate that follows the rear of the trench can reliably and smoothly cover the cultivation trench with soil while ensuring that the soil does not collapse or cause poor posture of the seedlings. To provide a rice field that can be well covered with soil so as not to disturb it, has a simple structure, and can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a side view of a rice transplanter, in which a float 1 whose rear part is elongated and has projecting parts 1a, 1a on both sides of the middle circumference near the rear is installed in the front-rear direction, and the front of the float 1 is Both transmission cases 6 each having a wheel 5 mounted thereon are extended on both sides of the rear of the engine E installed above the fuselage, and a planting depth adjustment lever 8 is installed between the planting case 7 at the rear of the fuselage and the rear of the float 1. A seedling platform 10 that can be reciprocated laterally is installed obliquely in front of the handle 9 that extends toward the rear of the machine, and both planting claws 11 extending below the seedling platform 10 are connected to the float 1.
It is constructed in the same manner as the conventional structure by installing seedlings A and A to be planted behind both protruding parts 1a and 1a.

Further, groove forming bodies 2, 2 are provided on both sides of the float 1, which are rear inner sides of both protruding parts 1a, and have an internally open vertically and a side triangular protruding part 2a at the front part.
are installed in series, and both groove-cutting bodies 2, 2 are installed so as to cut grooves under the field surface, respectively, and the fertilizer tank 12 is hung from the roll case 12a at the bottom of the fertilizer tank 12 mounted on the front side of the seedling stand 10. The lower parts of both the hoses 13 to be installed are connected to the upper parts of both the groove-cutting bodies 2, 2, and the fertilizer falling into the groove-cutting body 2 is placed into the groove-cutting groove and turned into fat fertilizer. and configure.

Cultivating soil plates A and A are respectively installed at the rear of both cultivating groove bodies 2 that are near and inward from the planting positions of the planted seedlings A and A. are both holes 15 into which both bolts 14 are inserted.
On both rear sides of both soil plates A, there are a front inclined plate 3 and a rear inclined plate 3, which are on the left and right sides from the rear of the trenching body 2, and whose respective longitudinal directions are inclined in an inverted C-shape to the opposite side. In addition to forming the plate 4, each plate is bent so that it is inclined forwardly high and rearwardly low, and
The rear inclined plate 4 is biased towards the planting seedling side with respect to the front inclined plate 3, and is slightly rearward, forming a staggered pattern, and the height of both inclined plates 3 and 4 is a trench that sinks into the rice field. The height of the upper half of the body 2 is the same as that of the upper half of the body 2, and the length of the front inclined plate in the lateral direction of the fuselage is
The soil covering amount of the front inclined plate is set to be larger than that of the rear inclined plate.

Therefore, during rice planting work, both planting claws 11 plant block seedlings on both sides of the rear of the float 1, and both planting groove bodies 2 are placed on the part of the rice field that is inside of the planted seedlings A and A. Fertilizer is fed out from the hoses 13, 13 through the trenches 13, 13 and passed through the trenching body 2 and thrown into the bottom of the trench, thereby performing lateral fertilization.

The soil plates A and A will follow and cover the rear of both groove bodies 2, but first, the preceding front inclined plate 3 will scrape the mud below the float 1 with its slope. As shown in Fig. 9, the soil is pushed over the top of the trench R in the direction of the planted seedlings A, and then the rear inclined plate 4 scrapes the mud on the side of the planted seedlings A with its slope. As shown in Figure 10, the mud is pushed toward the top of the planting groove, and the mud on both sides of the planting groove is sequentially covered without pushing the mud unilaterally toward the side of the planted seedlings. This means that it can be pushed over from the opposite side. Moreover, by increasing the amount of soil covered from the lower side of the float 1 and reducing the amount of soil covered from the side of the planted seedling A, the movement of mud near the planted seedling A is reduced, and the planting It is possible to prevent seedlings from falling over.

As described above, the present invention provides a rice transplanter that is equipped with a groove-making body that can make grooves on the rice field and apply fertilizer in the grooves on the side of the float that is on the side of the planted seedlings. It has a front inclined plate and a rear inclined plate whose longitudinal directions are inclined in an inverted V-shape to opposite sides, and whose front slope is high and rear low.Moreover, the amount of soil covered by the front inclined plate is larger than that of the rear inclined plate. Then, a cultivating soil plate formed so that the inclined plate is biased towards the planted seedling side and slightly rearward of the front inclined plate is connected to the side of the float that is behind the trenching body. Because of this structure, the soil plate running behind the trenching body can scrape the mud on both sides of the trench and press it down one after another, preventing the seedlings planted on the sides of the trench from falling over. It is possible to reliably and smoothly cover the trenches with soil while keeping the soil in good condition without causing poor posture, and it also covers the soil well so that the field surface is not disturbed so that the fertilizer in the trenches will not be washed away by water. Moreover, by increasing the amount of soil covered from the float side and reducing the amount of soil covered from the planted seedling side, it is possible to reduce the movement of mud near the planted seedlings during planting. It can prevent seedlings from falling over,
It has the advantage of having a simple structure and being able to be suitably implemented.
