Description

[Detailed Description of the Invention] The present invention relates to a trenching and seedling planting device for planting seedlings while creating trenches in a field.

Conventional planting equipment inserts a planting rod holding the seedlings into the soil and plants the seedlings, but if the field is hard, the roots of the seedlings will be damaged, causing damage to the plants, and the planting rods will wear out significantly. did.

The present invention provides a trench planting device that can simplify the driving mechanism of the planting rod by using the driving mechanism of the planting rod, and can also plant the seedlings without damaging the roots and the planting rod. A planting rod and a groove-making rod installed side by side are each pivoted to a shaft that moves in circulation, and the bases of the planting rod and groove-making rod are connected to different swinging arms to create the groove. It is characterized in that the rod is configured to make a groove before the planting rod.

The embodiments shown in the drawings will be explained below.
1 is equipped with an engine 2 in the front and a seedling stand 3 in the rear.
It is a machine body equipped with a transmission device for horizontal reciprocating motion, and a transmission device is installed inside.The front part of the swing chain case 5 is mounted on a shaft protruding from the transmission case 4. Wheels 6 are mounted at the rear of the swing chain case 5, , 6 are pivotally supported, and the front wheel 7 moves up and down in synchronization with the wheels 6, 6 via a link.

8 is a planting rod having a planting claw 9 at its tip, and a rod 10 slidably held in a holding cylinder 10' parallel to the planting claw 9 is lowered by a spring in the holding cylinder 10'. It is biased and has a seedling pushing body 11 at the lower part and a receiving plate 12 at the upper part.

As shown in FIG. 2, reference numeral 13 is a groove-making rod arranged along the outside of the planting rod 8, and a groove-making plate 13a facing below the lower end of the planting claw 9 is welded to the tip thereof. There is.

A crank arm 15a having a crank pin 15 is attached to the end of the planting shaft 14 that protrudes from the body 1 to both sides, and a regulating rod whose intermediate portion is swingably supported by the crank pin 15 is attached. 1
6 is arranged between the planting rod 8 and the groove cutting rod 13, as shown in FIG. Rotatably connected to the lower end of the movable arm 18 with a pin 19,
The middle part of the planting rod 8 is rotatably supported on the inner side of the shaft 20 which is attached to the front and is interlocked with circulation, and the middle part of the groove cutting rod 13 is rotatably supported on the outer side.
The base of the groove rod ₁₃ is pivotally supported on a swinging arm 21 having a length L1, and the base of the groove rod 13 is pivoted toward the front of the swinging arm 21, and has a length _L2 larger than _L1 . It is pivotally supported by a swinging arm 22, and the length _l2 of the groove cutting rod 13 that projects forward from the shaft 20 is larger than the projecting length _l1 of the planting rod 8.

In addition, the planting rod 8 and the planting groove rod 13 are the planting rod 13.
The tips of a pair of left and right arms 23, 23 protruding from a slightly forward part in the middle are connected by contacting the lower surface of the receiving plate 12 attached to the upper end of the rod 10, and are connected to the planting rod 8. As shown in FIG. 2, the tips of the groove rods 13 are bent toward each other and aligned on the extension line of the regulating rod 16.

Furthermore, since the grooving rod 13 is provided on the outside of the planting rod 8, when the grooving rod 13 is lowered to the lower limit, the halfway portion can be lowered regardless of the crank pin 15, and the grooving rod 13 can be lowered regardless of the crank pin 15. 13 and the planting rod 8 are pivotally supported on the left and right sides of the regulating rod 16, so their operation is stable.

Next, to explain the action, when the planting shaft 14 is rotated clockwise in the drawing, the crank pin 15 moves circularly, and the regulating rod 1 is rotated accordingly.
6 also moves in a circular motion, and the rear end moves in a circular arc back and forth under the control of the swinging arm 18. moves in a long elliptical motion up and down.

At the same time, the base of the planting rod 8 is controlled by the swing arm 21, so the planting claw 9 moves in a vertically long trajectory from the top of the apron 3a of the seedling stand 3 to the planting position, as shown in FIG. Since the base of the groove-making rod 13 is regulated by the swing arm 22, the groove-making plate 13a always moves from the notch of the apron 3a to a position deeper than the planting position of the planting claws 9. It moves up and down while drawing a trajectory b in a state lower than the planting claw 9.

Therefore, the groove plate 13a is ahead of the planting claw 9 by A1 when _scraping seedlings, and is ahead by _A2 just above the soil surface, but when it enters the soil, the planting claw Descend more rapidly and create a groove A ₃ deep.

At this time, the arm 2 protruding from the groove rod 13
Due to the differential movement between the planting rod 8 and the groove cutting rod 13 as described above, the receiving plate 12 supported at The seedling pushing body 11 moves up and down between points c ₁ and c ₂ , so that the seedling pushing body 11 is located above the tip of the planting claw 9 by b ₁ at the top, and is separated by b ₂ just above the soil surface, reaching the lower limit of descent. Then, the seedling is planted by moving slightly downward from the tip of the planting claw 9 and pushing the root part of the seedling into the groove formed by the groove plate 13a.

Furthermore, since the angle at which the planting claws 9 enter the seedling platform 3 is close to vertical, the seedling platform 3 can be gently tilted to prevent buckling and compaction of the bed soil for pine seedlings.

In the present invention, as described above, the planting rod and the grooving rod are respectively pivotally connected to a shaft that moves in circulation, and the bases of the planting rod and the grooving rod are connected to different swinging arms to control the grooving rod. The structure is such that the groove is cut before the planting rod, so even if the soil surface on which the seedlings are planted is hard, the planting rod will cut the groove before the planting rod, so the planting rod will not be damaged. It is possible to prevent damage to the seedlings as well as damage to the seedlings.

In addition, despite the provision of planting rods and ditching rods,
The grooving rod can be driven by the drive shaft of the planting rod, and the driving mechanism of the grooving rod can be significantly simplified, making it smaller and lighter, and reducing costs.
