Description

[Detailed Description of the Invention] The present invention relates to a support device for a furrower in a fertilizing section of a seedling transplanter.

That is, in the fertilizing section of the seedling transplanter, which is configured so that fertilizer is introduced from the lead-out pipe to the rear of the furrower, which is located on the side of the planting claw and creates a groove, the seedlings are At the time of planting, it is possible to reliably apply fertilizer in the trench while making good grooves on the side of the planted seedlings with a trencher, and when the machine turns and changes direction during work, the trencher can To provide a machine capable of turning smoothly together with a machine body so as not to disturb the rice field by pushing mud on the rice field, and to have a simple structure so that it can be suitably implemented.

Figure 1 shows a side view of the entire seedling transplanter. Engine E, etc. are installed above a longitudinally long float B that slides on the rice field, and wheels 4 with lugs are mounted on both sides of the float B. A handle 6 extends toward the rear upper part from the rear upper part of the transmission case 5 that is installed and extends to the rear upper part of the float B, and a seedling loading stand 7 installed diagonally in front of the handle 6 is placed above the seedling taking out stand 8. Retractable portions 9 on both sides of the rear side of the float B are provided with both planting claws 1, 1 which are installed to reciprocate and reach the seedling take-out stand 8 to scrape off one seedling.
The tip of the planting depth adjustment lever 10 installed on the rear side of the transmission case 5 and the part of the float B near the retracting part 9 are connected via the pin 11. They are connected to each other so that the planting depth can be adjusted, and the structure is similar to the conventional type.

Further, the fertilizer tank 12 below the handle 6 is supported by a stay 13 extending from the rear upper part of the transmission case 5, and the sprocket 16 of the shaft 15 of the feed roll 14 at the inner lower part of the tank 12 is fitted. , the sprocket 17 on the rear side of the transmission case 5 and the chain (not shown) of the sprocket 16 are wrapped around, and both outlet pipes 2, 2 are extended from the lower part of the tank 12 below the feed roll 14 to the lower side on both sides, respectively. death,
The lower portions of the lead-out pipes 2, 2 are supported by both stays 19 extending from support plates 18 fixed to both sides of the rear part of the transmission case 5, and the tips of the lead-out pipes 2, 2 are released on both sides of the rear part of the float B. The exits 2a are arranged in their respective directions.

A, A shows the entire groove making device, the whole is boat-shaped, the tip part 21 is formed into a pointed shape, and the upper part 22 is wider than the bottom part a so that the front part is hollow, and the side plate 23 is made. , 23, and both side plates 2
3 and 23 are extended rearward so that the rear part of the groove maker A is opened vertically, and a bending rod 25 fixed above the tip part 21 with a bolt nut 24 is extended from the front of the groove maker A downward. Configure it so that it appears.

In addition, a support rod 26 with one end fixed to the top surface of the upper part 22 of both groovers A, A is provided to extend obliquely forward toward the top of the tip 21, and the other end of the support rod 26 on the upper side extends in the front-rear direction. A support tube 27 is fixedly installed that tilts forward in a low front and high rear direction, and a support tube 27 that tilts forward in a low front and rear high direction in the front and back direction is fixed at the lower rear of the support plate 18 that is fixed on both sides of the rear of the transmission case 5. The support shaft 3 is extended, and the support tube 2
There is a seat plate 2 at the bottom of the support shaft 3, on which the shaft 7 is rotatably fitted.
8 and engage the cotter pin 29, so that both furrowers A, A are centered on the spindles 3, 3 at both sides of the rear of the float B, and on the outside of the planted seedlings P, P. The bottom part a is configured to be rotatable in the horizontal direction so that the bottom part a rises upward while remaining in a horizontal position in the front-back direction.

Note that the support tube 27 may be fitted to the support shaft 3 so as to be movable and adjustable in the vertical direction, so that the groove cutting device A can be installed so as to be vertically adjustable.

Further, FIGS. 8 and 9 show another embodiment, and parts denoted by the same reference numerals as those in the previous embodiment have the same structure, and include a support rod extending vertically from the upper surface of the upper part 22 of the groove maker A. At the upper end of 26', a horizontal support cylinder 27' is connected in the front-rear direction, and the lower part of the rod 3a hanging from the support plate 18 is bent to form a support shaft 3 that is horizontal in the front-rear direction. The seat plates 28, 28 are fitted to both ends of the support tube 27' fitted into the support tube 27', and a split pin 29 is engaged with the seat plates 28, 28.

When planting seedlings, the float B slides on the rice field with the body moving forward as shown by the arrow A by the wheels 4, 4, and both planting claws 1, 1 move behind the retracting parts 9, 9 of the float B. Seedlings are planted on the rice field respectively, and both furrowers A and A, which are pulled by the support shaft 3, move forward while approaching the outside of the planted seedlings P and P on both sides, and touch the rice field with the bottom a side. The fertilizer is discharged from the discharge ports 2a, 2a of the two outlet pipes 2, 2 as shown by the arrows B, when the grooves are made.
The fertilizer falls between the rear side panels 23 and 23 of A, and is fertilized directly into the trench, and is fertilized together with seedling planting.

In addition, when the seedling transplanter reaches the headland side of the field and turns to change its direction, both the furrowers A and A are pulled by the support shafts 3 and 3.
When the aircraft is in a state where it can rotate laterally as shown by the arrow C around point 3, the bottom part a rises above the rice field while rotating laterally as the aircraft turns. can follow the turning direction.

In the other embodiments shown in FIGS. 8 and 9, the groove makers A, A can similarly rotate laterally to follow the turning of the machine body.

In this way, the present invention is a seedling transplanter that is configured so that fertilizer is inputted from the lead-out pipe at the rear of the furrower, which is positioned to the side of the seedlings planted by the planting claw and creates furrows. In the fertilization section, the groove creator is formed into a boat shape with the rear part open upward and downward, and the groove creator is tilted forward in the front-rear direction at the rear of the machine;
Alternatively, since it is constructed so that it can be rotated laterally so that the bottom rises upwards around a horizontal upper support shaft, when planting seedlings, a boat-shaped groove can be installed on the side of the planted seedlings. The fertilizer released from the lead-out pipe while cutting the trench can be placed inside the trench and applied at the same time as planting seedlings. As the groover rotates laterally and the bottom rises upwards, it is possible to turn smoothly with the machine without disturbing the field surface by pushing mud, and it has a simple structure. It has the advantage of being suitable for implementation.
