Description

[Detailed description of the invention]

[00011

[Industrial Application Field] When planting seedlings, the present invention
This invention relates to a rice transplanter that can simultaneously spray pesticides such as insecticides or fungicides against pests on seedlings and spray herbicides against weeds. [0002] [Prior Art] Insect repellents for seedlings include those that kill insect pests by spraying them directly on the seedlings, and those that kill insect pests that are absorbed by the roots and die when the insects eat the seedlings. There are two ways to store it. [0003] Conventionally, planting seedlings is sometimes done by spraying crop-absorbing insect repellents, that is, spraying insect repellents that absorb insect repellents through the roots, and spraying herbicides on the surface of muddy soil at the same time. A rice transplanter designed for rationalization is JP-A-2-14511.
There is a technique described in Publication No. 5. [0004]

[Problems to be Solved by the Invention] However, with this conventional structure, the insect repellent that is absorbed through the roots is sprayed onto the mat-shaped seedlings placed on the seedling stand. A portion of the insecticide adhered to the plant and remained without being absorbed by the roots, meaning that not all of the sprayed insect repellent was used effectively, resulting in waste of the insecticide. [0005] The present invention aims to solve the above-mentioned drawbacks by devising the spraying of insect repellents. [0006]

[Means for Solving the Problems] The characteristic structure of the present invention for achieving the above object is that the seedling planting device is connected to the rear of the traveling machine, and the planting is carried out in the muddy soil near the seedlings. The system is equipped with an application device that buries absorption-type pesticides and a herbicide spraying device that sprays herbicides on the field.
And the effects are as follows. [0007]

[Action] Crop-absorbable pesticides, that is, insecticides and fungicides,
When planting, the pesticides are buried in mud near the seedlings, so that the pesticides either permeate into the bed soil of the seedlings, or the pesticides are absorbed from the roots by the roots that grow toward the pesticides. [0008]

[Effects of the Invention] As a result of the above structure, a good drug administration effect with less drug loss can be expected. [0009]

Embodiments Hereinafter, embodiments of the present invention will be explained based on the drawings. As shown in Fig. 1, a seedling planting device 1 is connected to the rear end of a link mechanism that can be raised and lowered and connected to the rear of the riding type traveling body, and the planting operation is performed at the rear of the seedling planting device 1. The fertilizer applicator 2 is provided with a fertilizer 2 that applies fertilizer in conjunction with the fertilizer 2, and a chemical spraying device 3 is further attached to the rear of the fertilizer 2. [00101 The above-mentioned seedling planting device] is configured in a 6-row planting type, and for planting, a seedling mounting table 4 is tilted downward after the seedlings are placed, and a seedling mounting table 4 is arranged horizontally at the rear and lower side of the seedling mounting table 4. Six planting mechanisms 5 and the like for cutting and planting seedlings one by one are attached to a planting transmission case 6 which also serves as a frame. [0011N Each of the above-mentioned planting mechanisms 5 is equipped with a planting rotation case 7 which is driven and rotated around the horizontal axis X1 at the center of the planting transmission case 6 on both sides of the rear thereof, and also has a planting rotation case 7 which is driven and rotated around the horizontal axis X1 in the center thereof. Attach planting claws 8, 8 to both ends of 7, respectively,
The planting claws 8, 8 are configured to cut out and plant seedlings while drawing a substantially elliptical trajectory as the planting rotating case 7 rotates,
One rotation of the rotating case 7 performs two planting operations, and the planting operation can be performed at high speed. [0012] The fertilizer application device 2 has six fertilizer application devices arranged in parallel in the horizontal direction corresponding to the planting rows, each including a fertilizer storage hopper 9 in the upper part, a rotary roll type feeding mechanism 10 connected below the hopper 9, and It consists of a downstream guide pipe 11 and the like that are connected to the lower part of the feeding mechanism 10, and the feeding mechanism 10 is configured to feed out a predetermined amount of fertilizer in conjunction with the rotation of the planting mechanism 5. In other words, as shown in FIG. 1, a connecting bracket 1-12 is installed and connected to the side of the rotating case 7 over both ends thereof, and the connecting bracket 1-12 is connected to the connecting bracket 1 at a part halfway between the rotating case 7 and the center of rotation of the rotating case 7. A push/pull rod 15 connects a position deviated by a predetermined amount from the oscillating end of the swinging arm 14 for swinging drive, which is integrally connected to the swinging roll 13 in the feeding mechanism] 0.
It is pivotally connected via. In this way, as the rotation case 7 rotates, the swing arm 1 is
4, that is, the rotary roll 13 is configured to reciprocate at a partial pitch and dispense a predetermined amount of fertilizer. [0013] The chemical spraying device 3 is arranged in six rows in parallel in the horizontal direction corresponding to the planting rows, and serves as an insect repellent application device that sows the insect repellent into the muddy soil on the opposite side of the fertilizer application position across the seedlings. The insect repellent spraying device 3A includes a spraying device 3A and a herbicide spraying device 3B that sprays the herbicide on the surface of the mud over substantially the entire width for seedling planting, and the insect repellent spraying device 3A includes a hopper 16 that stores the chemical;
Feeding mechanism 1 that feeds out a predetermined amount of medicine from below the hopper 16
7 and a downstream pipe 18 that is connected to the lower part of the feeding mechanism 17, and the herbicide spraying device 3B includes a hopper 19 that stores the chemical, and a feeding mechanism that feeds out the chemical every predetermined amount from the lower part of the hopper 19. 20, a rotating body 21 that scatters the dispensed drug with its rotational force, and the rotating body 21
It consists of a box-shaped guide member 22 with a downward opening that guides substantially all of the scattered chemicals spread across the width and falls onto the field. [0014] Feeding mechanism 17 of the insect repellent spraying device 3A
As shown in FIGS. 2 and 3, the supply port 23 of the hopper 16
A disk-shaped feeding member 25 having a large number of drug passage holes 24 formed along the circumferential direction is disposed below the disk-shaped feeding member 25 so as to be rotatable around the vertical axis X, and below the feeding port 23 . Drop guide port 26 is located at a location corresponding to the through hole passage trajectory at a different position from
It is configured by providing. On the other hand, the feeding mechanism 20 of the herbicide spraying device 3B has a disk-shaped feeding member 29 formed with a large number of chemical passage holes 28 along the circumferential direction below the supply port 27 of the hopper 19. It is arranged so as to be rotatable around Y, and a drop guide port 30 is provided below it at a position corresponding to the through-hole passage locus at a different position from the supply port 27, and further below it is driven to rotate at high speed by an electric motor 31. A rotating body 32 is provided. [0015] Feeding member 25 of the insect repellent spraying device 3A
The feeding member 29 of the herbicide spraying device 3B is interlocked with gears 33a and 33b formed on its outer periphery, and the gear 33a of the insect repellent spraying device is driven at low speed by the electric motor 34. ing. [0016] Insecticides and fungicides are used as the insect repellent.
