Similarly to the invention, when the spring material 38 is not provided, the ground surface E can be leveled by the dead weight of the rubbing plate 28 and the seed potato S can be embedded in the ground. Moreover, when the spring material 38 is provided, the ground surface E can be leveled more smoothly by its elasticity, and the seed potato S can be reliably embedded in the ground.

  A first embodiment of a seed seed direct seeder 10 according to the present invention is shown in FIGS. 1 to 3. This is to attach the rice seed pod S to the rear end of the agricultural power transfer machine 2 such as an agricultural tractor so that the seed pod S can be directly sown in the flooded rice field, and the leveling plate 21, the seed hopper 11 and the rubbing plate 28. It is characterized by having.

  The flat plate 21 is constructed in the left-right direction on the lower surface of the front end portion of the float 3 provided in the front-rear direction, and plays a role of uniformly leveling the ground surface E of the rice field. The seed hopper 11 is provided substantially above the middle part in the front-rear direction of the plurality of floats 3, and drops seed hoppers S on release portions P formed between the three floats 3. Further, the rubbing plate 28 is disposed in the release portions P at the rear end portions of the plurality of floats 3, and serves to rub the seed potato S sown in the release portions P from above and push it into the ground.

  In the present embodiment, the rubbing plate 28 is formed by bending the elastic metal plate into a side arc shape, and the front end portion thereof is fixed to a horizontal shaft 29 laid in the left-right direction at the rear end portions of the plurality of floats 3. ing. The horizontal shaft 29 is supported by a support member 34 formed by laterally arranging L-shaped steel. Further, the rear end rubbing portion 14a, which is the portion rubbing the seed potato S, of the rubbing plate 28 is fixed to the lower end portion of the vertical bolt 31 inserted through the horizontal girder 30 installed in the left-right direction behind the horizontal shaft 29. The adjustment nut (wing nut) 33 is screwed onto the upper end portion of the vertical bolt 31 protruding upward from the cross beam 30 and the rear end rubbing portion is interposed between the horizontal beam 30 and the rear end rubbing portion 14a. A spiral spring 32 for biasing 14a downward is fitted. Thus, the rear end rubbing portion 14a of the rubbing plate 28 is set so that the vertical position can be freely changed.

  The effect | action of this soy seed direct seeder 10 is demonstrated. The seed tractor S is dropped from the seed hopper 11 to the release part P (ground surface E) while the ground surface E is uniformly leveled by the leveling plate 21 by running the tractor 1 on the dropped rice field. At this time, since the ground surface E is leveled, the seed pod S that has fallen is located on a level surface without unevenness. From this state, the seed plate S is rubbed from above with the rubbing plate 28, and the seed plate S is poured into the ground. At this time, the seed potato S is sown on the ground surface E leveled by the leveling plate 21 and pressed by the rubbing plate 28 with an equal force, so that it is buried in the ground at a uniform depth. As a result, after filling with water, the seed pod S can be prevented from being lifted, rooted, or unable to germinate based on an excessive amount of pushing due to insufficient pushing amount, so that the seed pod S can grow well.

  In the present embodiment, the rear end rubbing portion 14a of the rubbing plate 28 is set so that the vertical position can be changed. Therefore, for example, when the rear end rubbing portion 14a is to be moved upward, the adjustment nut 33 is rotated in the clockwise direction. As a result, the vertical bolt 31 is raised, and the rear end rubbing portion 14a is also raised while being bent. On the other hand, when the rear end rubbing portion 14a is to be moved downward, the adjustment nut 33 is rotated counterclockwise. In addition, since the spiral spring 32 is fitted between the horizontal beam 30 of the vertical bolt 31 and the rear end rubbing portion 14a, the rear end rubbing portion 14a is always pressed downward with sufficient force by its elasticity. Thus, the seed potato S can be surely embedded in the ground.

  The seed seed direct seeder 10 according to the present invention can be manufactured by improving an existing rice transplanter. In this case, the leveling plate 21, the rubbing plate 28, and members attached thereto (the horizontal shaft 29, the horizontal beam 30 and the like) are detachably attached by fastening members such as bolts and nuts. Moreover, the seed fertilizer hopper 11 uses the existing fertilizer hopper. This can greatly reduce the investment in agricultural machinery.

This seed pod direct sowing machine 10 is attached to the rear end portion of the agricultural power transfer machine 2 such as a tractor in order to directly sown the rice seed pod S in the flooded rice field, and is also a flat plate device 20 according to the present invention. And a seed hopper 11.

  The flat plate device 20 forms a plurality of (six in this embodiment) cut recesses 22 at the rear end portion of the flat plate 21 provided in the left-right direction to level the ground surface E of the rice field, and each of the cut recesses. A so-called flat U-shaped sowing guide frame 23 is erected so as to surround 22, and further, the seed soot S sowed through the sowing guide frame 23 is rubbed into the ground by rubbing it from above into the ground. Intruded sheet 24 is provided. The flat plate 21 is composed of a central portion 21a and a main body portion 21b, and at least a connecting portion C provided at one location of the central portion 21a and the main body portion 21b. 3).

  The seed hopper 11 is provided immediately above the flat plate 21 and continuously supplies a predetermined number of seed hoppers S into the sowing guidance frame 23. The seed hopper 11 includes a feed hose 12 for supplying the seed hopper S into the seeding guide frame 23 without spilling the seed potato S.

The effect | action of this soy seed direct seeder 10 is demonstrated. By running the agricultural power transfer machine (tractor) 2 on the fallen rice field, the seed surface S is leveled from the seed hopper 11 while the ground surface E is uniformly leveled by the leveling plate 21 and water is removed at the same time. 23 is dropped on the ground surface E through the inside (usually about 100 grains per 1 m ² ). At this time, since the ground surface E is leveled by the flat plate 21 and water is excluded, the seeds S that have fallen are sown on the ground surface E without unevenness. Moreover, since the seed potato S is guided by the sowing guide frame 23, it falls to a predetermined location without being scattered around.

  From this state, the seed sheet S is pressed by the rubbing sheet 24 so as to be rubbed from above and embedded in the ground. At this time, the seed potato S is sown on the ground surface E leveled by the flat plate 21 and pressed by the rubbing sheet 24 with an equal force, so that it is buried in the ground at a uniform depth. As a result, the seed pod S can be prevented from being lifted up and rooted up reliably, and the seed pod S can be developed well.

  In addition, the rubbing sheet 24 in this embodiment is supported by a first support shaft 25 that has a front end portion laid on the seeding induction frame 23 on the left and right sides, and an intermediate portion thereof is secondly laid on the seeding induction frame 23 on the left and right sides. It is supported on the support shaft 26 via a chain piece 27 of adjustable length. Thus, the mounting posture of the rubbing sheet 24 can be adjusted, and the pressing force against the seed potato S can be adjusted.

This is an existing rice transplanter, and the flat plate 21 of the sowing seedling direct seeder 10 according to the present invention is attached to the lower side of the float 3 provided at the rear end portion thereof by fastening members such as bolts and nuts. It is attached detachably. The seed hopper 11 is configured by using a side fertilizer of a rice transplanter, and the seed pod S is dropped from there to a sowing guide frame 23 attached to the flat plate 21.

  Also in the sowing seed soot moving device 1, the sowing soy seed S does not rise or rise due to the operation of the flat plate device 20. In addition, since the seed seed direct sowing machine 10 is attached to the lower side of the float 3, the seed seed direct seeding mobile device 1 can be easily manufactured using an existing rice transplanter or the like.

  The flat plate device 20 can be configured as follows instead of the above-described configuration. That is, as shown in FIG. 8 to FIG. 10, the front upper end portion of the rubbing plate 28 arranged obliquely is rotatably supported by a support bar 35 laid horizontally on the right and left of the sowing guide frame 23, and the rubbing plate A vertical bar 36 is erected so as to be swingable from an almost middle portion of the bayonet 28. And the upper part of the vertical bar 36 is inserted in the insertion hole 37a of the support plate 37 erected on the seeding induction frame 23 on the left and right. In addition, a positioning member 40 having a diameter larger than the insertion hole 37a such as a nut can be attached to the upper end portion of the vertical bar 36, and the lower limit position of the rubbing plate 28 can be set.

  In such a configuration, when the rubbing plate 28 is formed thin with a lightweight material, the ground surface E cannot be strongly pressed only by its own weight, so the rubbing plate 28 and the support plate 37 of the vertical bar 36 are not provided. A spring material (spiral spring) 38 that presses the rubbing plate 28 downward may be fitted between the two. On the contrary, when the rubbing plate 28 has a sufficient weight, it is not necessary to provide the spring material 38.

  In the present embodiment, the dispersion plate 39 is provided on the front wall of the soot guide frame 23. This dispersion plate 39 is set so that the left and right width of the seed soot guiding frame 23 is set wide (about 10 cm), and the seed soot S introduced from the seed soup hopper 11 is arranged in all directions between the front wall of the seed soot guiding frame 23 and the support rod 35. It is for seeding in a state of being dispersed and dispersed on the ground surface E. Therefore, in the case where the left and right width of the soot seed guide frame is set to be narrow (about 3 cm) and the soy seed S is sowed in a straight line, it is not necessary to provide this dispersion plate 39.

  The flat plate device 20 having such a structure can be attached to the sowing seed sowing machine 10 or the sowing seed sowing moving device 1 according to the present invention. In that case, since the structure of the flat plate device 20 is simple, the manufacturing cost of these products can be suppressed.

  The flat plate device 20 according to the present invention can be attached to the float 3 of the agricultural power mobile machine 2 to constitute the seed pod direct sowing machine 10 and the seed pod direct sowing mobile apparatus 1 (see FIG. 1). It is also possible to configure the seed pod direct sowing machine 10 and the seed pod direct sowing mobile device 1 by attaching to the agricultural power mobile device 2 with 3 removed (see FIG. 4).
