Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) This invention is used for a seedling transplanter, and improves the posture and survival of seedlings by backfilling the holes that were created when the seedlings were planted. It is intended.

(Prior Art) As disclosed in Japanese Utility Model Laid-Open No. 59-147411 and others, there has been proposed a method in which a hole formed at the time of planting seedlings is backfilled with a clay clasp.

(Problems to be Solved by the Invention) These earth pulling tools are configured to rotate about an axis provided at a fixed position with respect to the machine body. Further, since the axis serving as the center of rotation is located at a relatively low position, there is a possibility that these may become an obstacle when the operation is stopped and the seedling planting machine is moved, or in other cases.

(Means for Solving the Problems) In order to solve the above problems, the present invention is directed to a swivel case 3 that swivels in an oval orbit whose tip is vertically long when viewed from the side.
And a seedling picking rod 1 which is provided at the tip of the swivel case 3 and scrapes one seedling therein out through the end of the seedling mounting table 6 during swivel, and swivel case 3 is swirled An extruder 2 that moves downward at the lower end inside and pushes out the seedlings held by the seedling picking rod 1 into the soil, and is attached to the swivel case 3 by the horizontal shaft 23 and rotates in synchronization with the swivel to raise. A seedling planting device in a seedling planting machine provided with a soil sill 8 for bringing soil into the seedling side in the initial stage.

(Operation) Since the present invention is configured as described above, when a seedling planting machine provided with this device is operated in a field with seedlings placed on the seedling mounting table 6, it operates as follows.

That is, while the turning case 3 moves forward by the power of the engine or the like, the tip turns in an elliptical orbit that is vertically long and narrow when viewed from the side. Then, the tip of the seedling picking rod 1 passes through the end of the seedling mounting table 6 in the middle of descending and scrapes off one seedling of the above-mentioned seedling. Then, when reaching the lower end, the tip enters the soil, the extruder 2 descends, and the extruder 2 pushes down the seedlings scraped and held. In this way, the seedlings are planted in the soil, but when the swivel case 3 starts to rise, the soil sack 8
Fell down to the soil surface near the seedling and pushed it, and the seedling rod 1
The hole made on the soil surface with the tip of the or the extruder 2 is backfilled.

When the transmission to the turning case is cut off, it automatically stops at a relatively high position as is well known, so that the earth-moving tool 8 also stops at a high position.

(Effect) As described above, according to the present invention, since the earth-moving tool 8 automatically backfills the holes formed when the seedlings are planted in the soil, the posture of the planted seedlings is good and there is a risk of collapse. There is no such thing and living is good. Since the soil container 8 is provided in the swivel case 3, there is no possibility of stopping the swivel case 3 at a high position and stopping the swivel case 3 to hinder the movement.

(Example) Next, the Example of this invention is described.

As shown in FIG. 1, the left end of the turning case 3 is supported by a body (not shown) by a link 4. As shown in FIG. 4, the arm 1 is attached to the end of the drive shaft 10 protruding from the machine body by the arm 1.
1 is fixed to form a crank, and the shaft 11 is supported at the center of the turning case 3 so that the turning of the shaft 11 causes the right end of the turning case 3 to turn in a vertically elongated oval orbit. There is.

The seedling rod 1 composed of a pair of left and right needles is fixed to the right surface 12 of the swivel case downwardly and obliquely with a screw 13, and when swiveling the swivel case 3, the tip of the swivel case swivels clockwise on track a. While descending, it passes through the lower end of the seedling mounting table 6 and scrapes off one seedling of the seedling on it.

The sliding rod 15 is attached to the swivel case 3 so as to slide along the seedling picking rod 1, and the pusher 2 is fixed to the lower end thereof. The middle of the swing rod 18 is attached by a shaft 19 in the swivel case 3, and the right side thereof is pushed down by a spring 22, and the right end 2
1 engages with the upper end portion 20 of the sliding rod 15, and the swing rod 18
When the shaft swings around the shaft 19, its right end 21 slides on the sliding rod 18
Is slid to move the extruder 2 up and down. When the cam 17 fixed to the shaft 11 comes into contact with the left end of the swing rod 18 and the arm 5 rotates clockwise from the position shown in FIG. 1, the left end of the swing rod 18 is moved counterclockwise (arrow B). When pushed and rotated once to reach the position shown in the figure, the left end of the swing rod 18 is pushed up by the spring 22 away from the step portion of the cam 17. Therefore, when the tip of the seedling picking rod 1 swivels on the track a to reach the position shown in FIG. 1, the pusher 2 descends by the elastic force of the spring 22 and holds the seedling on its lower surface 14
Push it into the soil. The lower part of the track a passes slightly below the field scene 7, and the seedling rod 1 and the pusher 2 dig a hole in the field scene 7.

As shown in FIG. 5, the earthen tool 8 is fixed to the tip of the rod 24 whose tip is divided into two, and the left end portion of the rod 24 swings on the horizontal shaft 23 to the tip of the swivel case 3. (Fig. 3). As shown in FIG. 3, the sliding rod 29 is attached to the swivel case 3 in the front-rear direction, the right end projects from this, and the pin 31 at the upper end of the rod 24 is engaged with the elongated hole 30 thereof. The right end of the connecting rod 28 is connected to the left end of the sliding rod 29, and the left end of the connecting rod 28 is connected to the arm 27 at the projecting end of the shaft 11. The rotation of the shaft 11 causes the connecting rod 28 to push and pull the sliding rod 29, and the rod 24 Is the horizontal axis 2
It is designed to rotate around 3. Then, as shown in FIG. 1 and FIG. 3, when the tip of the seedling rod 1 is at the lower end,
When the earthenware 8 is located to the left and starts to rise,
The sliding rod 29 moves to the left, and the right end of the elongated hole 30 is the pin 3
1 to the right, the rod 24 rotates in the counterclockwise direction around the horizontal axis 23 (C in FIG. 3) and scrapes the soil of the field scene 7 to the right seedling side, as shown in FIG. Be folded.

A coil spring 32 is attached to the horizontal axis 23 to urge the earthen tool 8 in the direction opposite to the arrow C direction. The stopper 33 provided on the swivel case 3 contacts the seat 34 of the rod 24 so as not to rotate further. The earthen implement 8 is formed in a box shape with upper and lower surfaces 25 and side surfaces. Reference numeral 9 in the drawing denotes a pin connecting the left end of the turning case 3 and the lower end of the link 4.
