The fertilizer 19 is arranged near the lateral side of the seedling planting location by the seedling planting mechanism 5, forms a groove in the field as the machine runs, and supplies fertilizer from the supply hose 18 into the groove. It is configured to go.

The interlocking rod 20d is connected to the operating arm 20c via a connecting member 20e made of sheet metal as shown in FIG. The connecting tool 20e and the interlocking rod 20d are formed by sandwiching the bending connecting part provided at one end of the connecting tool 20e and the end of the interlocking rod 20d passing through the bending connecting part. They are connected by a pair of lock nuts configured and mounted to be fixed. That is,
The connecting rod 20d is connected so that the connecting length of the connecting rod 20d to the connecting tool 20e can be adjusted.

As shown in FIGS. 1, 3 and 6, a sheet metal mounting member 27 is attached to the rear end of each of the chain cases 4 and 4 as an example of a pair of left and right fixing portions of the seedling planting apparatus 1.
Are connected to the upper end of a pair of front and rear round pipe posts 28 and 29 extending from each mounting member 27 by a support frame 30 in the lateral direction of the machine body.

The upper end of the front column 28 is connected to a link connecting member 31 attached to the front side of the support frame 30 so as to be rotatable around an axis 28b in the lateral direction of the body. The upper end side of the rear column 29 is provided with a rail support arm 32 extending rearward from the support frame 30.
To the link connecting member 33 connected to the
It is connected rotatably around b. Thus, the pair of front and rear columns 28 and 29 form swing links 28 and 29 that can swing about the axis in the lateral direction of the machine body with respect to both the mounting member 27 and the link connecting member 33. That is, each fertilizer apparatus main body 10 is connected to the chain case 4 via a four-link mechanism including a mounting member 27, a pair of front and rear swing links 28, 29, a support frame 30, and a link connecting member 33.

Therefore, when the four-link mechanism is swung, the four-link mechanism moves each fertilizer main body 10 in the front-rear direction while supporting their weight at a stroke. The position changes between the work mounting position shown in FIG. 1 and the non-work mounting position shown in FIG. That is, when the quadruple link mechanism is operated to swing forward of the fuselage and the rear swing link 29 comes into contact with the rearward stopper surface of the rubber stopper 34 attached to the mounting member 27 as shown in FIG. Due to the positioning action of the stopper 34, each fertilizer applicator main body 10 comes to the above-mentioned work mounting position located near the lower end side of the seedling mounting table 6 and above the seedling planting mechanism 5. When the quadruple link mechanism is swung to the rear side of the fuselage and the front swing link 28 comes into contact with the upward stopper surface of the rubber stopper 34, the positioning action of the rubber stopper 34 causes each fertilizer apparatus main body 10 to The non-work mounting position is located farther rearward from the lower end of the seedling mounting table 6 than the work mounting position.

This makes it possible to lock the four link mechanism in a swingable manner while preventing rattling due to running vibration or the like, and to fix the fertilizer applicator main body 10 to the work mounting position. Instead of rubber stopper 34,
A stopper made of a spring steel plate or a plastic material may be employed, and these are collectively referred to as an elastic stopper 34.

A spring 41 is attached to the front swing link 28 and the rear swing link 29. The spring 41 is attached in a state where the fertilizer applicator body 10 is slightly stretched and elastically deformed in a state where the fertilizer applicator body 10 is at the work attachment position. As the fertilizer applicator body 10 moves from the working mounting position to the non-working mounting position, the two swing links 28, 29 swing rearward with respect to the mounting member 27 to connect the spring link 28 with the spring. Since the distance between the point and the spring connection point of the oscillating link 29 changes to the enlarged side, the spring 41 is elastically deformed by being pulled more than when the fertilizer apparatus body 10 is at the work mounting position. As a result, the spring 41 moves the swing link 28,
29 is urged to the upright side to urge the fertilizer applicator body 10 to the work mounting position.

Each of the pair of front and rear swing links 28 and 29 is formed as a bent link having bent portions 28c and 29c at an intermediate portion. Then, the front swing link 28

That is, the rotation axis 28 with the support frame 30 as a connection point to the fertilizer apparatus body 10 on the upper end side.
b, a bent portion 28 with respect to the rotation axis 28a with the attachment member 27 as a connection portion to the chain case 4 on the lower end side.
c is located on the rear side of the fuselage, and the bending link 28c is located on the lower end of the seedling stay 8 provided on the seedling mounting table 6 and on the rear side of the seedling holding rod. The fertilizer applicator main body 10 is set in an assembling posture in which the fertilizer applicator main body 10 approaches the seedling mounting table 6 as much as possible so as not to interfere with the seedling holding rod.

Pivot shafts 28a, 29a for the mounting members 27 of the pair of swing links 28, 29;
The linear length between the support frame 30 or the pivot shafts 28b and 29b with respect to the link connecting member 33 is determined by the rotational axis of the interlocking rod 20d with respect to the power take-out body 21 and the pivot axis with respect to the swing arm 20c. Is set to be equal to the straight line length between. When the fertilizer applicator 10 is moved, the seedling planting mechanism 5 is stopped.
An imaginary straight line passing through the rotating shaft cores 28a, 29a on the 29 mounting member 27 side and the rotating shaft cores 28b, 29b on the fertilizer apparatus main body 10 side, and the rotating shaft center of the interlocking rod 20d on the seedling planting mechanism 5 side. Each of the rocking links 28 and 29 is maintained while maintaining a state in which the virtual straight line passing through the rotation axis of
Each rotation axis is set so that the interlocking rod 20d swings. Thus, the quadruple link mechanism operates the fertilizer apparatus main body 10 even while the interlocking rod 20d is connected to the swing arm 20c and the seedling planting mechanism 5.

As shown in FIG. 2, the supply hose 18 is supported by a hose support 36, and the hose support 36 passes from the mounting member 27 above the seedling plant 5, and the seedling plant The support arm 37 extends to the opposite side of the chain case 4 from the chain case 4. That is, when the main body 10 is moved and operated by the four-link mechanism, the supply hose 1
8, the receiving portion 18a is supported by the hose support 36 and does not move, and the feeding port 16b of the fertilizer apparatus body 10 comes off the receiving portion 18a of the supply hose 18 by itself, or returns to the receiving portion 18a of the supply hose 18 by itself. To match the availability of fertilizer.

As shown in FIG. 1 and FIG. 3, the mud that covers the seedling planting mechanism 5 and jumps up by the seedling planting mechanism 5 does not adhere to the fertilizer body 10 below each fertilizer body 10. A mud avoiding cover 24 is provided. The mud avoiding cover 24 is supported on the lower end side of the fertilizer collection container 23 attached to the fertilizer main body 10 so as to collect the powdered fertilizer as shown in FIGS. It is connected to the main body 10 so as to move integrally therewith.

That is, the mounting position of the seedling stay 8 mounted on the seedling mounting table 6 is adjusted so that the mat-shaped seedlings of the seedling mounting table 6 are prevented from floating from the seedling mounting surface. When the seedlings are taken out of the plant, or the seedling planting mechanism 5 is inspected or cleaned, the bag side rail 38 in the lateral direction of the machine body supported by the rail support arm 32 is used as an operating handle. The link mechanism is pivoted rearward to move the fertilizer applicator body 10 from the working mounting position to the non-working mounting position. Then, the mud avoiding cover 24 also moves with the fertilizer applicator main body 10 and the vicinity of the lower part of the seedling mounting table 6 and the upper part of the seedling planting mechanism 5 are planted so that operations such as seedling stay adjustment, seedling removal and cleaning can be easily performed. It is more open than during fertilization and fertilization work. At this time, a spring 41 is used to prevent the fertilizer applicator main body 10 from suddenly moving due to the weight of the fertilizer or the fertilizer.
Can be moved while being supported by In addition, interlocking rod 2
0d and the supply hose 18
