Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention relates to a float structure of a rice transplanter.

(B) Conventional technology Conventionally, the float of a rice transplanter has a concave portion formed in the center of the floor surface to reduce the resistance to water flow, improve the progress of the float, and sufficiently maintain the float function. It is also designed to be lighter in weight.

(C) Problems to be solved by the device However, when high-speed planting is performed in a deep field, the water that has entered the concave part formed on the bottom of the float is located on the lateral side of the float at the seedling planting position. It becomes a state that it spills out to one side and blows out, and as much water is stored in the planting position portion as much as that, the water depth becomes deep, and the planting depth is adjusted according to the originally constant water depth. Nevertheless, there was a drawback that the planting operation was inconsistent and stable planting work could not be performed.

(D) Means for Solving the Problems In the present invention, the float is formed from a wide frontal head that bulges in the left-right width direction and a rear half of the narrow float that is continuous behind the frontal head. The back end of the head and the rear half of the float are constricted on both sides to form a cutout, and the seedling planting position is placed in this cutout, and the center of the bottom of the front part of the float is located. In addition to providing a recessed part on the bottom, a narrow linear groove that communicates with the recess is provided in the center of the bottom of the float corresponding to the cutout, and further, on both sides of the bottom surface of the float corresponding to the cutout, parallel spacing It provides a float structure for rice transplanters, which is characterized by having a long projecting edge that extends substantially the same length as the groove in the front-rear direction, and the projecting edge has the same height over the entire length. It is a thing.

(E) Action / Effect According to this invention, when high-speed planting travel is performed in a deep-water field, the water flow flows through a concave portion formed in the center of the bottom surface of the float and a linear narrow groove communicating with it. However, at that time, the water flow entering from the front of the concave part of the float does not have to flow out to both sides in the straight narrow groove corresponding to the planting position behind it, even if it is blown out. Since the projecting edges that are linear and have the same height are formed on both sides of the projecting portion, it is possible to reliably prevent the water flow from being blocked by the projecting edges and protruding to the planting position. Therefore, even if high-speed planting travel is performed in a deep field, planting can be reliably performed without being affected by the water flow.

(F) Embodiment An embodiment of the present invention will be described in detail with reference to the drawings.
Shows a so-called rotary type rice transplanter, and in this embodiment, a riding type rice transplanter is shown.

The one shown in FIG. 1 is an overall side view of the rice transplanter (A), in which a prime mover (1) is mounted at the front of the airframe (a) and a handle (2) is provided behind it, and further after that. The seat (3) is provided on one side, and the front wheel (4) and the rear wheel (5) are provided on the front and rear parts of the lower part of the machine body (a). Attached device (B) is a connecting mechanism (6)
It is connected via the.

The planting device (B) receives power from the traveling machine from the center pin (8) provided at the front part of the planting case (7), and the rotary case ( 9)
The center of the rotary case (9) is rotatably mounted, and the claw cases (10) and (10) are connected to both ends of the rotary case (9), respectively. Is a planting nail (1
1) are connected in series, and when the rotary case (9) is rotated, the two claw cases (10) (10) perform a turning motion with planting, and the two claw cases (10) (10) With the planting claws (11), seedlings are cut and planted from the seedling table (12) standing upright in the opposite direction. (12a) is a seedling stand (12)
It is a support frame for supporting.

A float (M) is arranged below the planting case (7), (13) is a float support bracket, and (14)
Is a front support rod for supporting the front part of the float.

The gist of the present invention is, in such a riding rice transplanter (A), a groove-shaped concave portion (M- formed in the center of the bottom surface of the float (M).
The projecting edges (15) and (15 ') are provided on both sides of 1) and at the bottom of the float corresponding to the planting position (X).

That is, as shown in FIG. 2, the float (M) is bulged to the left and right of the forehead (16), and
6) The rear end of the float is slightly constricted, and the rear half of the float (17) extends in a narrow width from the rear end of the frontal region toward the rear.

Moreover, as shown in FIGS. 2 and 3, the bottom surface of the float (M) has a groove-shaped concave portion (M-
1) is formed, and the concave part (M-1) is the frontal part (1
In 6), the groove is formed so as to gradually expand toward the front, and a narrow parallel groove (M-2) is formed from the rear end. In addition, the narrow groove (M-2) is
7) It is extended to the middle part and the depth of the groove is shallower behind it.

Then, on both sides of the narrow groove (M-2) of the concave portion (M-1), the float bottom surface portion corresponding to the planting position (X) projects parallel to the groove (M-2). The rims (15) (15 ') are projected.

The ridges (15) and (15 ') are formed in a linear shape, and the front end is bent slightly outward so that the water flows as much as possible on both ridges (15) (1).
It is formed so that it easily gathers between 5 ').

The boundary between the rear end of the forehead (16) of the float (M) and the rear half of the narrow float (17) is formed by narrowing the side edges of the float to a narrow width. -3) is the position corresponding to the planting position of the seedlings, and therefore, the projecting edges (15) (15 ') are arranged at the positions corresponding to this cutout (M-3). .

Incidentally, FIG. 5 shows another embodiment of the projecting edges (15) (15 '), in which the projecting edges (15) (15') are formed in a straight line and the float is A groove maker (b) is provided in front of the cut-out part (M-3) formed on both side edges, and a soil plate (c) is projected behind the cut-out part (M-3). Therefore, the grooving device (b) is formed so that the linear projecting edges (15) (15 ') are located between the grooving plate (b) and the cultivating plate (b). When carrying out planting, prevent the soil that has been grooved from escaping toward the center of the float due to the projecting edges (15) (15 '), so that the soil for the cultivation soil is sufficient in the direction of the soil plate behind the projecting edge. We are trying to improve the soil cultivation effect.

Therefore, when high-speed planting is performed in a deep field, the water flow enters the concave part (M-1) on the bottom of the forehead (16), and then the narrow groove (M-2). Even if the water flow blows out to both sides when it goes inside, it can be blocked by the projecting edges (15) (15 ') and flow backward, preventing it from flowing into the planting position. The water depth of the plant is always kept shallow and high-speed planting work can be performed without being affected by water.
