Description

  The present invention relates to a flat and high ridge forming machine that is mounted behind a rotary tiller to form a flat and high ridge. In the present specification, the term “flat high ridge” refers to a comparison between ridges that are wider than a general ridge or kamaboko ridge, and whose upper surface is formed in a flat or gentle ridge shape. It refers to the high thing.

  As shown in Patent Documents 1 and 2, the basic configuration of the above-described conventional flat and high profile forming machine is a pair of left and right upper surfaces that form the upper surface of a wide flat and high plate and the both sides of the flat and high plate. A side molding plate and a pair of left and right front plates attached to the front end portion of each side molding plate in an inclined state with respect to the width direction of the kite in plan view are cultivated by a rotary tiller. The entire ridge is molded by the upper and side molding plates connected to the front plate while the soft soil immediately after is guided to the flat plate by the pair of left and right front plates. At the same time, ridge grooves are formed on both sides of the formed flat plate.

  FIG. 11 is a schematic cross-sectional view showing a state in the middle of forming a flat plate by turning the flat plate type molding machine at the heel end and alternately turning to the opposite direction in conventional flat plate forming, D indicates a complete ridge groove having a ridge width W formed between adjacent flat ridges K, and D ′ is formed between the most newly formed flat ridge K and unexpanded soft soil 95, An incomplete groove having a width W ′ narrower than the groove width W is shown. In the state shown in FIG. 11, when a new flat plate is to be formed, one of the soil guide plates 81 is in a state in which a part of the soil guide plate 81 is invaded into the incomplete groove D ′. The soil softened by tillage of the soil 95 is guided to the side of the flat plateau during molding by the soil guide plate 81. As a result, the soil 91 that has not been guided to the side of the flat height ridge K being formed by the soil guide plate 81 becomes a complete ridge groove D, and is a flat formed immediately before the center of the complete ridge groove D. The portion of the Takatsuki K that is close to the complete side surface 93 described later is left as the remaining soil 92.

  As a result, as shown in FIG. 11, a large amount of residual soil 92 remains in the lower end portion of the complete side surface 93 on the same side of the formed flat height ridge K in all the ridge grooves D in the sectional view of the flat height ridge K. Therefore, when the flat height ridge K is used as a reference, the remaining soil 92 is generated at the lower end portion of one side surface, and the remaining soil is not generated at the lower end portion of the other side surface. In FIG. 11, 94 indicates an “incomplete side surface” described later.

  As a result, in order to transplant the seedlings of the crop to the flat height ridge K, when moving both wheels of the transplanting machine straddling the flat height ridge K along the ridges D on both sides of the flat height ridge K, Due to the difference in the arrangement height of the wheels, the transplanter tilts, leading to a decrease in transplantation work efficiency and a decrease in the running stability of the transplanter. In addition, if the remaining soil 92 is continuously left in each dredging groove D, it becomes muddy when it rains, and during farming, the free movement of the farmer through the dredging groove D is harmed and the presence of remaining soil. As a result, there was also a problem that the drainage of the tuna groove worsened.

In the above embodiment, the ridge width W of the complete ridge groove D is adjustable, but when the ridge width W is constant, the movable soil guide plate C ₂ is not provided, and the fixed soil guide plate is provided. It is also possible to configure the soil guide plate C only by C ₁ . In this case, the tip portion of the soil guide plate C by only the fixed earth guide plate C _1, the sub-side molding plate B ₂ is rotatably mounted, said secondary side molding plate B _2, the adjustment rods 37, compression The complete side surface 93 or the incomplete side surface 94 of the flat height rod K is configured to be elastically pressed by the urging means including the spring 39 or the like. Even with this configuration, there is no generation of residual soil in the complete trench D portion.

In the above embodiment, the auxiliary side surface forming plate B ₂ is configured to elastically press the complete side surface 93 or the incomplete side surface 94 of the flat height plate K by the urging force of the urging means. When W is constant, the sub-surface molding plate B ₂ can be integrally attached to the tip portion of the soil guide plate C. Even in this configuration, the soil that is to remain in the trough is cultivated on the complete side surface 93 of the flat height trough K formed immediately before by the sub-side molding plate B ₂ , so that no residual soil is generated in the trough D. .

  Further, in the above embodiment, since the soil guide plate C extends obliquely forward and outward in a plan view, the soil that has been softened by the rotary tiller is a portion immediately before the flat plateau is formed. The effect of inducing is increased. However, the soil guide plate that performs the above-described function does not necessarily have to extend outward in a plan view obliquely forward, with the lateral direction orthogonal to the traveling direction of the flat and high profile molding machine as a limit. .
