いる。 Regarding the illustrated embodiment, to explain the structure of the float of the rice transplanter according to this invention, as shown in FIG.
A support frame F made of pipe material is connected to the book top link 1 and a pair of left and right lower links 2 so as to be able to rise and fall freely, and the front end of the support frame F has a gate shape that slopes forward and upward. The planting part P is connected to the standing frame part 3 forming a shape by a single upper top link 4 and a pair of lower right and left lower links 5 so that the planting part P can be raised and lowered.
This invention has been implemented in the following manner in a riding rice transplanter configured to carry out rice planting work by driving the machine body in a flooded field while towing the rice transplanter.

いるのである。 That is, as is usual, the planting part P is arranged on a seedling platform 6 which is tilted backward downward in the case shown in the figure, and is arranged at the lower end of the slope of this seedling platform 6 and rotates along a certain trajectory. The planting arm 7 is forced to enter into the seedling take-out port 6a of the seedling platform 6 that can be moved horizontally to cut out one seedling from a seedling pine (not shown) on the seedling platform 6. A planting arm 7 that grips and plants the seedlings in the field with its downward rotating end, and a planting section transmit that supports the seedling platform 6 and the planting arm 7 and transmits power to these driven bodies 6 and 7. Shion 8
and a float 9 that supports the above-mentioned planting members 6, 7, 8 from below, but the float 9 in this planting section P is
Based on this idea, it is constructed as follows.

る。 That is, as shown in Fig. 2, the illustrated riding rice transplanter is configured for planting in 6 rows, and three floats 9 are arranged in parallel, so that the rice transplanter can be used for planting in 6 rows.
While moving the aircraft on the side of L 1 , each float 9
Six rows of seedlings L2 are planted on both sides of the float.As shown in detail in Figures 3-8, each float 9 is constructed as follows.

持させるためのものである。 That is, the tip of the float 9 is raised upward as is customary in this type of float, but the tip on the bottom side of the float 9 is particularly shaped like a pointed portion 10 as shown in the figure. In other words, both side surfaces 11, 11 are formed into pointed portions 10 that protrude outward in the width direction of the float 9 toward the rear of the float 9. That is, as shown in FIGS. 4 and 6, if the width of the pointed portion 10 (however, as described later, this width is changed along the height direction of the pointed portion 10) is D. , the width D is made larger towards the rear of the float 9. As shown in the figure, both side surfaces 11 of this pointed portion 10 are formed into inclined surfaces that project forward toward the upper side of the surfaces 11. In other words, both sides 11
is not a vertical plane, but an inclined plane with the upper side tilting forward. Therefore, as shown in FIG. 6, when comparing the width D at the lower end of the pointed portion 10 and the width D' at the upper end at the same position in the front-rear direction of the float 9, the width D' is larger than the width D'. Width greater than D (D′＞
D), and the width of the pointed portion 10 gradually increases in the height direction of the pointed portion 10. Furthermore, in the illustrated case, as can be seen from FIG.
In the case shown in the figure, by suddenly changing the position approximately at the center of each side surface 11 in the length direction, the inner direction of the width direction of the float 9 (the tip side in the length direction of the side surface 11) is abruptly changed to a nearly right angle. The outer side of the float 9 in the width direction (the rear end side in the length direction of the side surface 11) is made gentler. 3-8, 12, 13 and 14 are mud discharge slopes formed on the upper surface of the float 9, 15 and 16 are mounting parts for support fittings, and in FIG. 1, 17 and 18 are respectively, Above mounting part 15,1
6 is used to suspend and support the float 9 on the planting section transmission 8 using a support fitting attached to the float 9.

る。 In addition, in FIG. 1, S is an auxiliary work provided by extending the support frame F to the rear of the planting part P and supporting it on a rear upwardly inclined gate-shaped rising part 19 formed at the extended end. This riding section S includes a passenger seat 20 for an auxiliary worker, a platform 21 below the front of the passenger seat 20, and a platform 21 that stands up slightly tilted forward from the front end position of the platform 21. A certain gate-shaped guardrail 22, etc.
It is configured with the following. Similarly, in FIG. 1, 23 is a passenger seat of the machine T, 24 is a hydraulic lift arm provided on the machine T, and 25 is a tie rod connecting this hydraulic lift arm 24 and the lower link 2. The raising operation raises the planting part P for each support frame F. 26 is a transmission shaft that transmits power from the machine T in the direction of the planting part P. In Figures 1 and 2, 27 is the machine T and support. A pair of left and right auxiliary springs stretched between the frames F support the support frame F by pulling it upwards, and 28 is a pair of left and right auxiliary springs stretched between the upright frame portion 3 and the planting portion P of the support frame F. The planting part P is supported by a pair of left and right auxiliary springs that can be pulled upwards. Furthermore, in FIG. 1, reference numeral 29 indicates a preliminary seedling platform supported by the seedling platform 6, and 30 indicates a pair of left and right tails supported on the rising portion 19 of the support frame F via parallel links 31 so as to be movable up and down. A wheel 32 supports the passenger part S from below by raising and lowering the tail wheel 30 via the parallel link 31.

のような長所を備えたものとなつている。 The rice planting work using the illustrated riding rice transplanter is carried out as usual by the planting part P while the machine T is towing the planting part P and traveling as described above, and in that case, When an auxiliary worker rides on the riding section S and performs auxiliary work such as monitoring the planting status of the planting section P or replenishing seedling mats from the preliminary seedling platform 29 to the seedling platform 6, the machine T is The worker sitting on the seat 23 only has to concentrate on operating the machine T, which greatly reduces the burden and fatigue. Considering that it is structured as follows, it has the following advantages in particular.

行の影響を極減するものとなつている。 That is, the float 9 according to this invention has a tip portion 10 on the bottom side with a pointed portion 10 in which both side surfaces 11 protrude outward in the width direction of the float 9 toward the rear of the float 9.
Therefore, while the rice transplanter is running in a flooded field, muddy water flows smoothly along both sides 11 of the pointed part 10, and the movement of the float 9 causes disturbances in the muddy water in the field. As a result, the amount of water that is applied to the seedlings is greatly reduced, and the negative effects such as crushing of the seedlings that have already been planted in the already planted row L1 are greatly reduced. Since the muddy water flows smoothly along both sides as described above, the running resistance of the float 9 is reduced, and the float 9 moves smoothly. In particular, the float 9 according to this invention is
Both sides 11 of the pointed portion 10 described above are
Since it is formed into an inclined surface that protrudes forward toward the upper side, waves of muddy water that are rippled as the float 9 advances are suppressed above the both sides 11 of the pointed portion 10. As a result, the ripples of muddy water are minimized, which also eliminates any negative impact on the already planted seedlings in the adjacent row L1 , and as a whole, the impact of running the float 9 on the adjacent surface of the planted rows is minimized. It is expected to decrease.

In addition, an increase in running resistance due to the sloped side surface 11 on the tip side of the pointed portion 10 is avoided, and the effect of suppressing ripples is sufficiently exhibited on the rear end side of the pointed portion. The waves of muddy water that are slightly rippled on the tip side of the pointed portion 10 are also blocked by other adjacent floats 9 and do not reach the adjacent row L1 .
