Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a seedling planting device provided with a device for spraying, for example, a chemical agent for insect repellent on a mat-like seedling placed on a seedling stand.

[Conventional technology]

In the seedling planting apparatus of this type, conventionally, a drive source for spraying the above-mentioned chemicals onto the mat-shaped seedlings was not provided with a dedicated drive source by utilizing a machine vibration of a rice transplanter or the like as a drive source. For example, Japanese Examined Patent Publication No. 59-26249).

[Problems to be solved by the device]

However, in this case, since the machine vibration is used as power, the amount of drug released due to the vibration is not constant, and the timing of release is also variable, and the seedlings are taken out at regular intervals. The drug was not evenly applied to the mat-shaped seedlings that were delivered toward the mouth.

An object of the present invention is to focus on the vertical feeding mechanism of the seedling placing table and to provide the one in which the medicine can be sprayed to the mat-shaped seedlings as expected by setting the drive source rationally.

[Means for Solving the Problems]

The feature of the present invention is that a drug spraying device for spraying the drug to the mat-shaped seedlings on the seedling placing table is provided above the seedling placing table equipped with a vertical feeding mechanism for feeding the mat-like seedlings to the seedling taking-out port. Along with the provision, the medicine feeding mechanism of the medicine spraying device is operated in cooperation with the vertical feeding operation of the vertical feeding mechanism so that a predetermined amount of the medicine is fed out. Are linked to each other, and their actions and effects are as follows.

[Action]

According to the above feature, when the vertical feeding mechanism feeds the mat-shaped seedlings to the seedling take-out opening, the vertical feeding operation of the vertical feeding mechanism is transmitted to the drug feeding mechanism of the drug spraying device via the linking device,
By operating this medicine feeding mechanism, the mat-shaped seedling is moved to the seedling take-out opening by driving the vertical feeding mechanism, and at the same time, a predetermined amount of the medicine is fed by the power from this vertical feeding mechanism to the upper surface of the mat-shaped seedling. It will be dropped and scattered.

In other words, in the present invention, since the drug spraying device is arranged above the seedling stand, the drug can be sprayed on the upper surface of the mat-shaped seedling by utilizing the self-weight of the drug.
Since the feeding mechanism of the chemical spraying device is operated by the power from the vertical feed mechanism, the spraying amount can be made uniform as compared with the case where it is operated in the non-interlocking state, and moreover, it is special for driving the chemical spraying device. It is not necessary to form a transmission system.

[Effect of device]

Therefore, it is possible to disperse a desired amount of the drug onto the mat-shaped seedlings by driving the drug spraying device without disposing a dedicated drive source by disposing the drug spraying device and the drive system of the drug spraying device. It was
