Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling planting device for a transplanting machine for transplanting soil-grown seedlings that have been raised to ridges in a field.

[0002]

2. Description of the Related Art A conventional planting device for a transplanter is provided with a beak which can be opened and closed vertically by forming a pair of front and rear parts and swinging about an upper fulcrum to open and close the lower part (for example, (See Japanese Laid-Open Utility Model Publication No. 5-34812), and with the seedlings sandwiched between the beaks, the beak is lowered to pierce the ridge to form a planting hole, and the beak gap is provided between the beaks. There is a plant in which the soil-bearing seedlings held in 1 are dropped and transplanted by opening the beak. When the seedlings are dropped, the soil-grown seedlings fall downward along the inner wall surface of one of the front and rear beaks, and the soil-grown seedlings are planted in the planting holes.

[0003]

However, in the planting device of the transplanter having such a beak, when the beak is pierced into the ridge, the resistance of the soil causes the beak from the gap between the front and rear beaks. Soil may enter the inside. For this reason, there is a possibility that the soil invasion lifts the soil-grown seedlings held in the beak, and the holding posture of the seedlings deteriorates. Also, when soil that has entered the beak adheres to the lower end of the inner wall surface of the beak, the soil that adheres becomes a resistance when the beak is opened and the soil seedlings are dropped along the inner wall surface. In some cases, it hindered a smooth fall, and the soiled seedlings were caught in the soil and the posture of the soiled seedlings collapsed, resulting in planting in an inclined state. In addition, there are problems such as the collapse of seedlings due to the adhered soil and the poor posture of holding the seedlings with soil due to the accumulation of adherent soil, which all adversely affected the seedling planting.

Therefore, the present invention solves the above problems,
An object of the present invention is to provide a seedling planting device for a transplanter that enables good seedling planting.

[0005]

The present invention has taken the following technical means in order to achieve the above object. That is,
A pair of beaks 62 that can be freely opened and closed is provided so as to be able to move up and down. The beaks 62 pierce the ridges 14 when they descend and form a planting hole 39, and the beak 62 is fitted into the planting hole 39.
In a planting device of a transplanting machine in which the soiled seedlings 38 held in between are dropped by opening a beak 62 to be planted, the beak 62 includes a pair of openable and detachable outer beaks 63 forming a planting hole 39. And a pair of openable and closable inner beaks 64 for holding the soil-embedded seedlings 38 arranged inside the outer beak 63. When the soil-embedded seedlings 38 are planted, the inner beak 64 is replaced by the outer beak 63. It is characterized by including an interlocking mechanism 74 for performing the opening operation after the opening operation.

According to this, when the outer beak 63 is pierced into the ridges 14, even if the soil intrudes into the inside through the gap between the outer beaks 63 due to the resistance of the soil, the resistance of the soil that has penetrated is determined to be the inner beak. Since it hardly reaches 64, soil does not enter the inside of the inner beak 64, so that the holding posture of the soil seedling 38 can be maintained in a good state. Since the soil does not adhere to the inner wall of the lower end portion of the inner beak 64, the earthed seedling 38 can be smoothly dropped and the seedling dropping posture can be prevented from collapsing.

Also, the interlocking mechanism 74 allows the outer beak 63
In contrast, by opening the inner beak 64 with a delay, even when soil adheres to the inner wall of the lower end portion of the outer beak 63, the soil seedling 38 contacts the soil adhered to the outer beak 63 when the soil seedling 38 falls. Therefore, it is possible to smoothly drop the soil-bearing seedlings 38 and prevent the seedling soil from collapsing due to the accumulation of adhered soil and the falling posture of the soil-bearing seedlings 38 from collapsing (claim 1).

Further, according to the present invention, the outer beak 63 and the inner beak 64 are provided with a lower portion that can be opened and closed by swinging with an upper portion as a fulcrum, and the outer beak 63 can swing together with the outer beak 63. The push piece 68 is provided, and the push piece 68 is capable of contacting the inner beak 64, and the contact piece 72 is swingable together with the inner beak 64. The outer beak 63 and the inner beak 64 are in contact with each other in the closed state. Piece 72
Are arranged with a gap in the swinging direction of the pushing piece 68 with the swinging of the outer beak 63 in the opening direction with respect to the pushing piece 68, and the pushing piece 68 and the contact piece 72 are arranged in the outer beak. Only the outer beak 63 is opened until the outer beak 63 and the pushing piece 68 swing and the pushing piece 68 abuts on the abutting piece 72 from the closed state of the inner bill 63 and the inner beak 64.
After the pushing piece 68 comes into contact with the abutting piece 72, the pushing piece 6
The interlocking mechanism 74 is configured to push the contact piece 72 by means of 8 to open the inner beak 64 together with the outer beak 63.

In the present invention, the outer beak 63 and the inner beak 64 are combined with the pushing piece 68 that constitutes the interlocking mechanism 74.
By interlocking with the contact piece 72 and the contact piece 72, the inner beak 64 can be opened and closed with a simple structure, and the opening operation of the inner beak 64 with respect to the outer beak 63 can be easily delayed. Item 2). Further, the present invention provides
It is characterized in that the inner wall surface 64A of the inner beak 64 is formed of a resin, preventing soil from adhering to the inner wall surface of the inner beak 64 that holds the soil-grown seedlings 38, and reducing the weight ( Claim 3).

At the upper part of the guide cylinder portion 51, the guide cylinder portion 51 is provided.
A partition plate 57 is provided which is capable of expanding and contracting the receiving port of the soil-embedded seedling 38. A receiving bracket 54 is fixed to the upper rear outer surface of the guide cylinder portion 51.
The front end of a support frame 55 is fixed to the bolt 4 by a bolt, and the support frame 55 is extended forward so as to surround the guide cylinder 51 and is fixed to the left side surface of the guide cylinder 51. Then, the support frame 55 is provided with a receiving member 55a having a screw hole, and on the other hand, on the left side of the upper part of the partition plate 57, an adjusting plate 58 having a long hole 59 elongated in the front-rear direction is provided. The long hole 59 of the adjusting plate 58 and the receiving member 55a
The partition plate 57 is attached to the guide cylinder portion 51 so that the front-rear position can be freely changed within the range of the length of the long hole 59 by fitting the same with the screw hole of and fixing with the bolt 60.

A state in which the soil-grown seedlings 38 are supplied to the planting cylinder 50 and then the soil-grown seedlings 38 are planted in the ridges 14 by the planting cylinder 50 will be described below. When the planting cylinder 50 is near the top dead center of the locus Y shown in FIG.
The seedlings with soil 38 transferred from the seedling tray 36 to above the planting cylinder 50 are dropped into the upper portion of the planting cylinder 50.
At this time, the partition plate 57 provided on the guide tube portion 51.
By changing the position according to the size of the seedlings, seedlings, etc. of the soil-grown seedlings 38 supplied in advance, it is possible to prevent the soil-grown seedlings 38 from falling within the guide cylinder portion 51. In addition, soil seedling 38
Is dropped into the guide tube 51 with a slight forward tilt,
The lower part of the soil-bearing seedling 38 collides with the partition plate 57 located at the rear side, and the posture thereof can be corrected to the upright state.

Then, the soil-grown seedlings 38 fall down through the receiving opening of the guide tube portion 51 and are sandwiched and held between the inner beaks 64 at the lower portion. In this state, as shown in FIG. The outer beak 63 of the planting cylinder 50 is stabbed into the ridge 14 near the bottom dead center of the locus Y (see FIG. 1). And the planting cylinder 5
With the backward movement of 0, the interlocking tool 77 acts and the outer beak 6
3 is opened back and forth, and the hole formed when the ridge 14 is pierced is expanded to form the hole 39 for planting. Further, at this time, the interlocking mechanism 7 is operated after the outer beak 63 starts to open.
Until the pushing piece 68 forming part 4 abuts the abutting piece 72, only the outer beak 63 is opened and the inner beak 64 is kept closed (see FIG. 2). After the contact with the contact piece 72, the pushing piece 68 pushes the contact piece 72 with the opening operation of the outer beak 63, whereby the inner beak 64 opens (see FIG. 3). Then, the soil seedlings 38 held by the opening operation of the inner beak 64 drop into the planting holes 39, and planting is performed.

By the way, when the outer beak 63 is thrust into the ridge 14, the soil may penetrate into the outer beak 63 due to the resistance of the soil when the outer beak 63 is stabbed from between the front and rear outer beaks 63. Even if it does, the resistance of the soil that has entered the outer beak 63 is small, and this soil hardly enters the inner beak 64. Further, since the lower end of the inner beak 64 is located higher than the lower end of the outer beak 63, the soil that has entered the outer beak 63 does not reach the inner beak 64, and the outer and inner beaks 64 Since the gap is provided between 63 and 64, the soil can enter the gap and prevent the soil from entering the inner beak 64. Therefore, the soil-bearing seedlings 38 held by the inner beak 64 are held in an upright posture without being affected by soil intrusion.

When the seedling 38 with soil is dropped, soil does not adhere to the inner wall surface of the lower end portion of the inner beak 64. The seedlings will not be destroyed by the soil. Then, in order to cause the opening movement of the inner beak 64 later than the outer beak 63 to drop the soil seedling 38, the outer beak 6
The soil attached to the inner wall surface of the lower end of No. 3 has no influence, and it is possible to plant the soil-grown seedlings 38 in an upright posture.

The distance from the swing fulcrum (pivot 71) of the inner beak 64 to the contact piece 72 is greater than the distance from the swing fulcrum of the outer beak 63 (mounting pin 67) to the contact surface 69 of the pushing piece 68. Since the distance to the contact surface is short,
The swinging amount of the inner beak 64 is larger than the swinging amount of the outer beak 63, and the opening speed of the inner beak 64 is faster, which results in the inner beak 64 being opened later than the outer beak 63. It is possible to correct the delay in the timing of dropping the seedling 38.

FIG. 10 shows another embodiment of the present invention. In this embodiment, the contact piece 72 constituting the interlocking mechanism 74 is the same as that of the first embodiment described above, The pushing piece 68 is the mounting pin 6 of the outer beak 63.
7, a protruding piece 88 protruding upward and an adjusting bolt 89 screwed into a female screw formed on the protruding piece 88 toward the contact piece 72.

In the present embodiment, the amount of protrusion (screwed position) of the adjusting bolt 89 toward the contact piece 72 can be adjusted to adjust the delay of the opening operation of the inner beak 64 with respect to the outer beak 63. I am able to do it. The present invention
The design can be changed as appropriate without being limited to the above embodiment.

[0035]

As described in detail above, according to the present invention, the beak is a pair of openable and closable outer beaks that form a planting hole.
It is composed of a pair of openable and closable inner beaks that are placed inside the outer beak to hold soil-grown seedlings, and has an interlocking mechanism that causes the inner beak to open after the outer beak opens. , When piercing the outer beak into the ridge,
Even if soil invades into the interior through the gap between the outer beaks due to the resistance of the soil, the resistance of the soil that has penetrated hardly reaches the inner beak, so the soil will not penetrate into the inner beak, and The holding posture can be maintained in a good state. And since the adhesion of soil does not occur on the inner wall of the lower end of the inner beak, the seedlings with earth fall smoothly.
It is possible to prevent the seedling drop posture from collapsing. Furthermore, by opening the inner beak with respect to the outer beak, even if soil adheres to the inner wall of the lower end of the outer beak, the earthen seedling will not come into contact with the adhered soil even when the soil seedling falls. , The falling of soil seedlings is made smooth, and the collapse of seedling soil due to the accumulation of adherent soil and the collapse of the falling posture of soil seedlings are prevented, and good soil seedlings can be planted ( Claim 1).

Further, according to the present invention, since the outer beak and the inner beak are interlocked by the interlocking mechanism composed of the pushing piece and the abutting piece, the inner beak can be opened and closed with a simple structure and the outer beak can be opened and closed. It is possible to cause a delay in the opening operation of the inner beak with respect to (claim 2). Further, according to the present invention, by forming the inner wall surface of the inner beak with resin, it is possible to prevent the soil from adhering to the inner wall surface of the inner beak that holds the soil-grown seedlings, and to reduce the weight (claim 3). ).
