Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a seeding processing section of a seeding plant used in a pre-process of growing pine-like seedlings for a rice transplanter.

[Conventional technology]

As the above-mentioned seeding plant, for example,
As shown in Publication No. 111716, a soil supply device, an irrigation device,
A seeding device and a soil covering device were installed side by side, so that the seeding process from supplying bed soil to covering the soil could be carried out in an assembly line.

[Problem that the invention seeks to solve]

In this way, conventional seeding plants are able to sow a large amount of seeds with almost no human intervention. It is not uncommon for seedlings to become stuck or to cause bridging phenomenon depending on the moisture level, and it is difficult to maintain uniformity in the amount supplied to each seedling nursery box and distribution on the soil surface, often resulting in poor sowing.

Therefore, we have workers who constantly monitor the soil surface where seeds are sown to determine whether the sowing conditions are appropriate, and if a defect is detected, they immediately check to ensure that the amount of seeds to be sown is appropriate. It was necessary to adjust the seeding device to ensure that This became one of the keys to making the seeding process completely unmanned.

An object of the present invention is to promote complete unmanned sowing process by entrusting the monitoring of the sowing status on the bed soil surface to electrical means.

[Means for solving problems]

The characteristic configuration of the present invention is that an imaging device for capturing images of the soil surface is provided between the seeding device and the soil covering device, and this imaging device is used to analyze the sowing situation based on the captured image information and determine whether it is appropriate. In addition to being connected to an image processing device for making judgments, this image processing device is equipped with means for analyzing the distribution of sown seeds and means for analyzing the supply amount of sown seeds from captured image information, and these means can be switched. Its functions and effects are as follows.

[Effect]

That is, before the soil is covered with soil, the soil surface on which the seeds are sown is imaged by the imaging device. Next, an image processing device connected to the imaging device analyzes the seeding situation based on the captured image information and determines whether it is appropriate. The image processing device is equipped with a means for analyzing the distribution of sown seeds and a means for analyzing the supply amount of sown seeds. uses means to analyze the distribution situation. In addition, in the case of thick sowing for raising young seedlings, the method is switched to analyze the amount of supply based on the shade of color. In short, an appropriate analysis method is selected and used in consideration of the sowing situation in that case.

〔Effect of the invention〕

As a result, it has become possible to monitor the sowing status on the soil bed surface with high accuracy using electrical means instead of workers, making a significant step toward completely unmanned sowing.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

As shown in FIG. 1, a seeding plant for producing pine-shaped seedlings is constructed by connecting a seedling box supply section A, a seeding processing section B, and a seedling box stacking device C.

The seedling box supply unit A includes a feed conveyor 2 that sends 1 g of stacked seedling boxes, and an elevator unit 3 that lowers the 1 g of seedling boxes from the feed conveyor 2 to a working level in a suspended state. and a seedling-growing box feeding device 4 that takes out the seedling-growing boxes 1 one by one from the group of seedling-growing boxes 1g from the elevator unit 3 and sends them out in the horizontal direction, and a sheet feeding device 4a that feeds the sheeting paper to the seedling-raising boxes 1. It is configured.

The seeding processing section B includes a conveyor 5 that transports the seedling growing boxes 1 from the seedling growing box feeding device 4 in a mounted state.
and a bed soil supply device 6 that supplies bed soil to the seedling raising box 1.
, a watering device 7 that sprays water on the bed soil, a sowing device 8 that sows rice seeds on the bed soil, and a soil covering device 9 that covers the seedling raising box 1 with soil after sowing.

The seedling box stacking device C includes a lift mechanism 10 that holds the seedling boxes 1 continuously fed in by the transport conveyor 5 in a substantially horizontal shelf shape and lifts them upward; A transverse feed mechanism 11 with a reciprocating structure sends out the seedling boxes 1 in a substantially horizontal state to a stacking work position, and a transverse feed mechanism 11 that sends out the seedling boxes 1 from the lift mechanism 10 by the transverse feed mechanism 11 at approximately the level at which they were sent out. An opening/closing shelf mechanism 12 that holds the seedling box 1 in a horizontal state and opens on both sides to allow the seedling box 1 to fall after the full width of the seedling box 1 reaches approximately above the stacking position in the feeding direction of the seedling box 1; In order to sequentially place the seedling raising boxes 1 from the mechanism 11 on the transporting cart 13 at the stacking work position, the elevator mechanism 14 is configured to move downward every time a seedling raising box 1 is stacked on the transporting cart 13. There is.

This seeding plant is configured to continuously send out seedling raising boxes 1, sowing seeds in the seedling raising boxes 1, and stacking the seedling raising boxes 1 after sowing, so that seedling raising can be carried out in a stacked manner until germination. , the seedling raising boxes 1 stacked on the transport trolley 13... are the transport trolley 1
As shown in FIG. 2, the seedlings are sent to the budding unit 15, where they are allowed to germinate under predetermined humidity and temperature conditions, and then transferred to the seedling raising shelf 17 for greening by the seedling box loading device 16, where they are further grown. It is becoming more and more common.

Between the seeding device 8 and the soil covering device 9, an image is taken of the soil surface each time the seedling raising box 1 is transported;
A color video camera CA is provided as an imaging device that outputs captured image information. This color video camera CA is connected to an image processing device 18 that quantizes the image information, analyzes the seeding situation, and determines whether it is appropriate.

This image processing device 18 converts it into a binary pigment image corresponding only to the color of the rice seeds on the bed soil surface, calculates the number of seeds extracted for each small area, and determines whether the sowing distribution is appropriate. In addition to determining the amount of seed sown on the bed soil surface as the average gray value of the image,
whether the gray value is within the set range,
In other words, it is equipped with means for determining whether the amount of sowing is appropriate. The means for determining the sowing distribution and the means for determining the supply amount are realized by a software method of the image processing device 18, and their switching is linked to the adjustment of the supply amount of the sowing device 8. will be carried out. When the supply amount is low, judgment is made based on the sowing distribution, and when it is large, the judgment is made based on the sowing amount. Further, a buzzer BZ is connected to the image processing device 18, and is configured to sound when it is determined that the seeding situation is not appropriate to issue a warning to the operator.

The lower side portion of the conveyor 5 located below the soil covering device 9 is tilted downward in order to cope with the height difference between the height level at the seeding processing section B and the height level at the seedling box stacking device C. be. Further, an inclined conveyor 5a whose lower side is inclined downward is interposed between the inclined rear end and the conveyor 5 on the side of the seedling box stacking device C. This inclined conveyor 5a substantially connects the seeding processing section B and the seedling box stacking device C, and is preferably as short as possible considering the size of the entire seeding plant. However, if it is too short, the inclination angle will become steep.
When the seedling growing box 1, which has been transported in a horizontal position by the seeding processing section B, reaches the front end of the inclined transport conveyor 5a, it may fall down significantly downward, causing the bed soil to shift or bounce. It is necessary to determine the length so that the angle of inclination is not too steep. Therefore, as described above, the lower side of the conveyor 5 on the side of the seeding processing section B is also bent downward to make the overall slope gentle.

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings by the reference numerals.
