Abstract

PURPOSE:To provide a seeder capable of simplifying peripheral equipment and of installing more seeding tables, so designed that a lifting member for raising soil upward from the approximate center of plural ridging-receiving positions and a dividing member for distributing the ridging from said lifting member to the ridging-receiving positions are installed to enable said both members to be shared in an easy manner. CONSTITUTION:The objective seeder in which plural seeding tables 27... are installed in an identical working room 3 is constituted as follows: A conveyor 24 for raising soil upward from the approximate center of plural ridging- receiving positions and a dividing member 26 for distributing the ridging from said conveyor 24 to the ridging-receiving positions are installed. Because of raising soil upward of the approximate center of the plural ridging-receiving positions using said conveyor 24, said member 26 can be constituted in a simple fashion along with easy sharing of both the conveyor 24 and the member 26.

Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention comprises, for example, a seeding stand equipped with a soil container, a seeding machine, a soil covering machine, etc., a floor tank is provided above the loading/unloading machine, and the soil covering machine The present invention relates to a seeding device that automatically and continuously performs sowing operations by installing soil-covering tanks above the seedlings and continuously supplying seedling growing boxes to the seeding platform.

``Prior Art'' Conventionally, as shown in Japanese Utility Model Application Publication No. 51-146229, a soil container, a seeding machine, etc. are mounted on a seeding table, and an above-the-floor tank installed above the soil container is loaded via a floor conveyor. There was a technology to supply the floor surface.

"Problems to be Solved by the Invention" The above-mentioned conventional technology only provides a single seeding table, and by adding more seeding tables, it is necessary to also add peripheral mechanisms. There were problems such as not being able to do it easily.

[Means for Solving the Problems] However, the present invention provides a seeding device in which a plurality of seeding tables are installed in the same work room, and a lifting member that lifts soil approximately above the center of a plurality of soil receiving positions; The present invention is characterized in that a member is installed for distributing the soil from the rising member to the soil receiving position.

"Function" Therefore, since the soil is lifted up approximately above the center of the plurality of soil receiving positions by the raising member, the distribution for distributing the soil can simplify the structure of the member, and the raising member and the distribution can be used in common. This makes it easy to simplify peripheral equipment and increase the number of sowing tables.
