Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a float arranged on both outer sides of a body of a transplanter.

[0002]

[Prior Art]

 Generally, in transplanting machines such as riding rice transplanters in which a center float and a side float that slide on the rice field support the planting area, seed recesses are provided on the side floats located on both outsides of the machine. It is known that the side float is formed in a gate shape in a plan view.

[0003]

[Problems to be solved by the present invention]

 By the way, in the conventional gate-shaped float, the left and right legs have the same width by providing a seedling planting recess with a rear opening at the center in the width direction. For this reason, none of the legs are very wide, so it is not possible to completely erase the marks of the wheels located in front of them with only the legs located inside the aircraft, especially on both sides of the wheels. There is a problem that it is more difficult to level the wheel marks when both lug wheels with overhanging lugs are attached, and when one of the legs has a wide part to eliminate the wheel marks. However, there was a problem that the state of muddy water flowing from the rear end of both legs into the recess for planting seedlings changed and disturbed the seedling posture. The present invention was devised to solve the above-mentioned problems. The side float is formed in a gate shape, and the marks of the wheels mounted in the front are completely leveled. It is an object of the present invention to provide a float for a transplanter that can perform planting work smoothly without disturbing the seedling posture by the muddy water flowing along the float.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the technical means taken by the present invention is a gate-shaped float which is provided on both outer sides of the machine body and has a seedling planting recess having an opening at the rear in the middle in the width direction. The two legs of the gate-shaped float are formed into a wide fox leg located outside the machine body and a wide leg inside the machine body. The feature is that the length to the end is extended longer than the wide leg.

[0005]

[Action]

 Therefore, according to the present invention, when carrying out the transplanting work, the wide legs located inside the machine completely erase the traces of the wheels located in the front and level the field scene. The muddy water flowing along both sides of the float flows from the rear end toward the center of the recess for seedling planting, but the length from the seedling planting position to the rear end of the foxtail leg is larger than that of the wide leg. Since it also extends for a long time, the muddy water that flows along the outside of both legs will flow into the center of the recess for planting seedlings in the same flow state, and the muddy water will not disturb the planting posture of the seedlings. .

【Example】

 Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Reference numeral 1 denotes a traveling machine body of a passenger rice transplanter exemplified as a transplanter, and an engine section 6 covered with a hood 5 is mounted on a front portion of a machine body frame 4 having front wheels 2 and rear wheels 3. A driver's seat 7 is arranged behind it. A four-row planting section 8 is attached to the rear of the traveling vehicle body 1 via a link mechanism 11 including an upper link 9 and a lower link 10 so as to be able to move up and down. Reference numeral 12 is a hydraulic cylinder for moving up and down the link mechanism 11, and 13 is a steering handle.

Reference numeral 14 is a power transmission case of the planting section 8. The power transmission case 14 is composed of a planting case 15, a drive case 16 and the like. A seedling planting rod 17 is provided. Above the power transmission case 14, a seedling mounting table 18 is supported so as to be reciprocally movable left and right, and below the power transmission case 14, a float 19 sliding on a rice field is vertically swingable via a swing link 20. Is attached to. The rotation shaft 21 provided in the drive case 16 is supported at the rear end of the link mechanism 11, and the entire planting portion 8 is free to roll.

As shown in FIG. 1, the float 19 has a center float 22 arranged in the center of the machine body and side floats 23, 23 arranged on both outer sides of the machine body. The center float 22 supports the planting section 8 and senses the elevation of the planting section 8 with respect to the rice field, and operates the hydraulic cylinder 12 to control the elevation position. Reference numeral 24 is a recess formed on both sides of the rear end of the center float 22.

The side-float 23 is a gate-shaped float in which a seedling planting recess 25 in the front-rear direction, which is open only at the rear, is formed in the middle portion in the width direction. By forming the seedling planting recessed portion 25 at a position deviated from the center of the side float 23 toward the outer side of the airframe, both legs of the gate-shaped float are provided with the plow foot portion 26 located outside the airframe and the inside of the airframe. And the wide leg portion 27 located at. Further, on the open side of the seedling planting recess 25, a thin portion 28 is formed on the wide leg portion 27, and a recess 29 in the front-rear direction is formed on the thin portion 28 so as to open backward and to the seedling planting recess 25 side. There is. In addition, the length of the fox leg portion 26 extends from the seedling planting position by the seedling planting rod 17 to the rear end longer than the length to the rear end of the wide leg portion 27 and protrudes rearward. It is in a state. Reference numerals 30 and 31 denote recesses that are provided at the rear outer ends of the wide fox leg portion 26 and the wide leg portion 27 and open rearward and sideward.

The center float 22 is disposed in front of the side float 23, and an imaginary line connecting the rear end of the center float 22 and the rear ends of the wide leg portion 26 and the narrow fox leg portion 27 is directed rearward. It has become widespread. Further, the side float 23 is arranged so as to fit within the outermost locus of the enpron guard 32 and the apron 33, which are arranged at a position visible from the driver's seat 7, and in front of the side float 23. The rear wheel 3 is located.

In the above-mentioned configuration, when carrying out the transplanting work, the float 19 slides on the paddy field along with the traveling of the aircraft, and the seedling planting rod 17 that operates to plant the seedling planting recess 25 and the center float 22. The seedling P is planted between the side float 23 and the side float 23. At this time, since the wide legs 27 of the side float 23 formed in the gate-shaped float are located inside the machine body, even if both lug wheels are attached to the machine body, the wheel marks are completely erased. The field scene can be leveled. The muddy water flows into the center of the seedling planting recess 25 from both sides of the side float 23, but the muddy water flowing along the outside of the wide leg 27 flows in through the wide rear end portion, The muddy water flowing along the fox leg portion 26 flows in through the ridged rear end portion extending to the rear, so that the muddy water flow conditions are almost equal and the posture of the planted seedlings P is disturbed. Absent. Further, since the rear ends of the center float 22 and the side float 23 are arranged in a divergent shape toward the rear, the muddy water that flows out rearward through the facing gap between the center float 22 and the side float 23 also naturally spreads toward the rear. It becomes like a flow. Therefore, the muddy water flowing out to the adjacent shoots on the side of the machine can be reduced as much as possible, and the adverse effect on the planted seedlings P ₁ can be reduced. On the other hand, at the time of traveling of the aircraft, if the driver sitting in the driver's seat 7 turns while looking at the apron guard 32, even if the side float 23 cannot be seen, the side float 23 is inadvertently contacted with the ridges or the like. It is possible to reliably prevent the risk of damage by hitting.

[0012]

[Effect of the device]

 In short, according to the present invention, in the gate-shaped float provided on both outer sides of the machine body and provided with the seedling planting concave portion having a rearward opening in the widthwise middle portion, both legs of the gate-shaped float are connected to each other. It is formed on the outside of the wide fox leg and the wide leg located inside the machine body, and the length from the seedling planting position to the rear end of the above-mentioned broad fox leg is longer than the wide leg. Since it is extended, the wide legs located inside the body of the gate-shaped float can completely erase the traces of the wheels and level the field scene. Even if the muddy water that flows along the outer side of the gate-shaped float flows toward the recess for planting seedlings, the width from the seedling planting position to the rear end extends longer than the wide legs. Muddy water flows into the recesses for planting seedlings from the limb legs in almost the same state as the wide legs, so muddy water does not disturb the posture of the seedlings, and transplant work can be performed in an orderly manner.
