In the vegetable transplanting machine Y having the above-described configuration, the gist of the present invention resides in that a drug dispensing device F that can perform drug dispensing simultaneously with seedling transplantation is provided, and the drug dispensing device F is provided in front of the transplanting device. A grooving plate 51 attached to the covering arm 54 is provided, and a drug supply hose 53 provided with a shutter device 52 at a distal end is provided above the grooving plate 51. A sprinkling guide portion 63 for guiding the medicine E falling from the medicine supply hose 53 into the groove H formed by the groove cutting plate 51 is formed on the back of the medicine supply hose 53.
[0025]
That is, as shown in FIG. 3, the dispensing device F includes a groove cutting plate 51 that forms a groove H in a ridge G on a covering arm 54 that supports a covering ring 15 at a rear end at a position in front of the planting claw 31. A medicine supply hose 53 having one end connected to a medicine tank (not shown) is disposed above the grooved plate 51, and a shutter device 52 that can be opened and closed at the end of the medicine supply hose 53 is provided. And the medicine E supplied from the medicine supply hose 53 is dropped on the grooved plate 51 by the opening operation of the shutter device 52.
[0026]
Therefore, the medicine E is scattered in the groove H formed in the ridge G by the grooving plate 51, and the potted seedling a is transplanted by the planting nail 31 to the place where the medicine E is scattered, and the soil is covered. The soil will be covered by the ring 15.
[0027]
Since the groove cutting plate 51 is connected to the soil covering arm 54, it moves up and down in the same manner as the earth covering ring 15 and is linked to the depth of the planting claws 31 entering the soil. Therefore. The groove H can be cut at a uniform depth with respect to the pot seedling a. Further, the lower end opening of the drug supply hose 53 is formed in a narrowed small hole shape so that an appropriate amount can be sprayed.
[0028]
The shutter device 52 is driven by a cam 56 attached to a planting claw drive shaft 55, which is an output shaft of the planting transmission case 30, to synchronize with the vertical swinging motion of the planting claw 31 and to lower the lower end of the drug supply hose 53. The opening can be opened and closed.
[0029]
That is, a roller 58 is rotatably attached to one end of a bracket 57 provided in the vicinity of the planting transmission case 30, and the other end of the crank 61 is provided with a guide cylinder 60 provided with a valve body 59. 3 and a spring 62 is interposed between the crank 61 and the bracket 57 to move the crank 61 in the direction in which the valve body 59 opens the lower end opening of the chemical hose 53, that is, in the clockwise direction in FIG. It is kept in the biased state.
[0030]
Further, the cam 56 in this embodiment is formed by forming two substantially continuous concave portions 56a and 56b on the outer peripheral surface of the disk, and the roller 58 of the crank 61 is provided at a portion other than the concave portions 56a and 56b. In this case, the valve body 59 is pushed in the direction of closing the valve body 59 against the spring 62, but the spring 62 pulls the valve body 59 in the opening direction in the concave portions 56a and 56b, thereby opening the lower end opening of the drug supply hose 53, and Falls into the grooved plate 51 through the guide cylinder 60. In this case, the valve element 59 opens and closes twice at substantially the same time, so that a desired spray amount of the medicine E can be obtained from the relationship with the diameter of the lower end opening of the medicine supply hose 53.
[0031]
Further, as shown in FIG. 4, a sprinkling guide portion 63 that receives the medicine E and guides the medicine E into the groove H formed by the groove cutting plate 51 is provided on the back of the groove cutting plate 51. Therefore, the medicine E is smoothly sprayed into the groove H. Then, the transplant nail 31 rushes into the location where the medicine E is sprayed, so that the pot seedling a is planted.
[0032]
As shown in FIG. 4, the distribution guide portion 63 is formed in a gutter shape, and has a gradually narrowing width as it goes downward. In addition, the dispersing guide portion 63 is positioned so that the center line thereof coincides with the center of the planting claw 31, and the tip of the drug supply hose 53 is positioned at the position of a circle X indicated by a dashed line. It is located. That is, the planting claws 31, the grooving plate 51, and the drug application device F are arranged on substantially the same straight line. Reference numeral 64 denotes a support rod for the grooved plate 51.
[0033]
Here, the actual operation of the medicine dispensing apparatus F will be described with reference to FIG.
[0034]
FIG. 5A shows a state immediately after the seedling transplanting operation by the vegetable transplanter Y is started. The groove cutting plate 51 enters the soil to form a groove H in the ridge G. At this time, the shutter device 52 of the drug dispensing device F is in the closed state. In this way, it is good to form the groove H, and it is possible to spray the medicine E into the soil.
[0035]
When the shutter device 52 is opened by rotation of the cam 56 (see FIG. 3), as shown in FIG. 5B, the medicine E falls through the guide cylinder 60 and is formed on the back of the grooved plate 51. The scatter guide section 63 guides the inside of the groove H along the groove cutting plate 51. Since the medicine E is sprayed into the groove H immediately after cutting the groove H, the medicine E surely enters the soil.
[0036]
The transplanting nail 31 and the shutter device 52 are operated in synchronization with each other, and as shown in FIG. 5C, the shutter device 52 is closed and the transplanting nail 31 is moved toward the location where the medicine E is sprayed. Rushes.
[0037]
Then, as shown in FIG. 5 (d), the planting claws 31 open to release the potted seedlings a, and the planting claws 31 rise. At this time, even if the medicine E is repelled by the opening operation of the planting nail 31, the medicine E is in the groove H, so that the medicine E can be maintained in a state of being scattered in the soil.
[0038]
Next, as shown in FIG. 5 (e), the groove H is filled with the earth covering ring 15, and the medicine E is positioned around the pot seedling a. Therefore, a certain medicinal effect can be expected, and the growth of the seedling can be improved.
[0039]
【The invention's effect】
According to the present invention, a groove plate attached to the covering arm is provided in front of the transplantation device, and a drug supply hose provided with a shutter device at a distal end portion is provided above the groove plate. Further, a spray guide portion for guiding a medicine falling from a medicine supply hose into a groove formed by the groove-cutting plate is formed on a back portion of the groove-cutting plate, so that the medicine is surely sprayed into the soil. The drug is not splashed by the implanted nail.
[0040]
Further, since the groove cutting plate is attached to the soil covering arm, the depth of the groove is interlocked with the depth of the planting claws penetrating into the soil, and the groove can be cut at a uniform depth with respect to the seedling. This ensures that the drug is sprayed around the seedlings.
[0041]
From the above, the medicinal effect of the drug is enhanced, and the growth of the seedling can be improved.
