Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention is provided with a seeding platform equipped with, for example, a soil-filling machine, a seeding machine, a soil-covering machine, etc., and a bed soil tank is provided above the soil-filling machine. The present invention relates to a seeding device that automatically and continuously performs seeding work by installing soil-covering tanks above each seedling machine and continuously supplying seedling growing boxes to the seeding platform.

``Prior art'' Conventionally, as shown in Japanese Utility Model Application No. 51-146229, a soil container, a seeding machine, etc. are mounted on a seeding table, and a conveyor is used to carry soil into a soil tank installed above the soil container. A technology was developed to supply bed soil through .

"Problems to be Solved by the Invention" In the above-mentioned prior art, since the bed soil carrying conveyor was installed vertically, the bed soil supply position to the conveyor was close to the sowing work position, and the work space was blocked by the conveyor. This makes it difficult to improve work efficiency and worker safety, and because the soil tank is integrally connected to the top of the soil filling machine, the large capacity of the soil tank is difficult to achieve. There have been problems in that it is not easy to centralize the supply of bedding soil by converting the seedbed or sharing the bedding tank with other seeding beds, and it is not easy to improve the bedding soil supply function.

Further, in the conventional technology, the starting end of the bed soil carrying-in conveyor is located at a lower position than the floor surface for installing the seeding table, and the bed soil outlet side of the bed soil supplying hopper that feeds the bed soil to the starting end side of the bed soil carrying-in conveyor is set at a lower position than the floor surface for installing the seeding table. Because it was positioned lower than the surface of the hopper, it was possible to prevent the bed soil transferred from the hopper to the conveyor from scattering to the surrounding area. As a result, dust on the floor or workers are likely to fall into the hopper, and foreign matter may easily get mixed into the hopper floor soil, making it impossible to perform work around the hopper safely, etc. There was a problem.

Furthermore, as shown in Japanese Unexamined Patent Publication No. 51-74807, there is a technology to install a bed soil transport conveyor diagonally, and as shown in Japanese Utility Model Application No. 47-25302, a large-capacity floor tank is installed above the bed soil hopper. However, in each of the above-mentioned conventional technologies, all the components were placed on the floor where the seeding table was installed, so as the equipment such as the soil tank became larger, the equipment was expanded only above or to the side of the seeding table. In addition to having functional and manufacturing cost problems, such as increasing the height of the plant, the overall height only increases upwards and the width increases accordingly, making it difficult to improve sowing workability. There are problems such as not being easily possible, especially those in which the bedding outlet side of the bedding outlet side is located lower than the floor surface for installing the seeding table, and the bedding soil input opening edge of the bedding soil supply hopper is located higher than the floor surface. Therefore, there are problems such as it is not easy to improve the workability and safety when transporting bed soil to the hopper, and it is not easy to improve the bed soil processing function in the hopper. It was hot.

``Means for Solving the Problems'' However, the present invention provides a device in which a soil filling machine, a seeding machine, etc. are mounted on a seeding table, in which a bed soil carrying conveyor is installed diagonally so that its terminal end is higher than its starting end. At the same time, a large-capacity bedding tank facing the end of the conveyor is provided independently at a position higher than the seeding platform, and a bedding outlet of the bedding tank is connected to a small-capacity bedding hopper provided in the soil filling machine. On the other hand, the starting end of the bed soil carrying-in conveyor is located at a lower position than the floor surface for installing the seeding table, and the bed soil outlet side of the bed soil supply hopper that feeds bed soil to the starting end side of the bed soil carrying-in conveyor is connected to the floor surface. The hopper is located at a lower position than the floor surface, and the rim of the bed soil input opening of the hopper for supplying bed soil is located higher than the floor surface.

"Function" Therefore, by installing the bedding conveyor at an angle, the bedding supply position can be set at an arbitrary position away from the seeding table, and the working space around the seeding table can be blocked off by the conveyor. Since the soil tank is not exposed to water, it is possible to easily improve work efficiency and worker safety compared to the conventional method, and because the soil tank is installed independently at a higher position than the seeding table, The soil tank can be easily enlarged, the amount of soil stored per operation can be increased, and the number of feeding operations can be reduced compared to the conventional method. Moreover, the soil tank can be connected to the soil hopper of the soil filling machine. By storing the bedding soil in multiple stages, the installation location of the seeding platform is no longer restricted from the bedding tank, making it easier to centralize the supply of bedding soil by sharing the bedding tank with other seeding platforms. In particular, since the edge of the bedding input opening of the bedding soil supply hopper installed semi-underground is higher than the floor surface for installing the seeding platform, the bedding soil can be moved from the bedding supply hopper to the starting end of the bedding conveyor. The hopper has a structure that can easily prevent dust from scattering, and the rim of the hopper for feeding soil can prevent dust on the floor or workers from falling into the interior of the soil supply hopper. It is possible to prevent foreign matter from being mixed into the bed soil of the bed soil supply hopper, and work around the bed soil supply hopper can be performed more safely than before.
