Abstract

PURPOSE:To prevent occurrence of mistaken feed of fertilizer instead of seed or vise versa, wrong blending, etc., by dividing a tank with a cover into a fertilizer storage chamber and a seed storage chamber by a partition wall, equipping one of the chambers with an inner cover and maintaining the inner cover upright between both the chambers by a spring member during opening of the tank. CONSTITUTION:A tank 11 equipped with a cover 21 is arranged on feed rolls, the interior of the tank is divided by a partition wall 24 in to a fertilizer storage chamber 25 and a seed storage chamber 26 and one of the chamber is provided with an inner cover 27 in such a way that the inner cover is opened and closed in the same direction as the cover 21. Consequently, since one of the fertilizer storage chamber 25 and the seed storage chamber 26 is closed with the inner cover 27 even if the cover 21 is opened and since the inner cover 27 is maintained upright between both the chambers by a spring member 33 when the inner cover 27 is opened, mistaken feed of fertilizer instead of seed or vise versa or mistaken blending is prevented. When the cover 21 is closed, since the inner cover 27 is simultaneously closed and locked by a locking member 35, workability is also improved.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a tank device for a fertilizing and seeding machine.

(Prior art) In a fertilizer seeding machine, for example, a tank with an upward opening is placed above the feed roll, and this tank is covered with a single lid that can be opened and closed freely, and the inside of the tank is partitioned with a partition wall. Some are divided into a storage room and a seed storage room.

(Problems to be Solved by the Invention) In the conventional tank, the tank is covered with a single lid, so when the lid is opened, the fertilizer storage chamber and the seed storage chamber are separated. We will open up together.

For this reason, when feeding fertilizer or seeds, there have been problems such as mistakes being made, or seeds getting into the fertilizer side or fertilizer getting into the seeds side.

Therefore, an object of the present invention is to provide a tank device for a fertilizing and seeding machine that prevents the mistake of putting fertilizer and seeds in, and also prevents seeds from entering the fertilizer side or fertilizer from entering the seed side. .

(Means for Solving the Problems) The technical means taken by the present invention to achieve the above-mentioned object is to arrange a tank 11 with an upward opening above the feed roll 39, and to cover the tank 11 with a lid 21. In a tank device for a fertilizing and seeding machine in which the inside of the tank 11 is divided into a fertilizer storage chamber 25 and a seed storage chamber 26 by a partition wall 24, the tank 11 is provided with a lid and is pivotably supported on the partition wall 24 inside the lid body 21. an inner lid 27 that opens and closes one of the fertilizer storage chamber 25 and the seed storage chamber 26;
and is attached to the tank 11 so that the lid body 21 is opened and closed in the same direction as the inner lid 27, and a spring member 3 is provided between the inner lid 27 and the tank 11 to hold the inner lid 27 in an upright state when opened.
3, when the lid body 21 is closed, the inner lid 21 is attached to the spring member 33.
A locking means for locking against the elasticity of the locking member is provided.

(Function) The inner lid 27 of the tank device according to the present invention is attached to the seed storage chamber 26.
Taking the case where the fertilizer is provided on the side as an example, when supplying fertilizer to the tank 11, open the lid 21 and enter the fertilizer storage chamber 25.
Add fertilizer to. At this time, the seed storage chamber 26 is covered with an inner lid 27 to prevent fertilizer from being put in incorrectly or from entering the seed storage chamber 26. Next, when supplying seeds to the tank 11, when the locking means is released, the inner lid 2
1 is flipped up by the spring member 33 and the seed storage chamber 26
is opened, and the inner lid 27 is held in an upright position by the spring member 33.

As a result, when putting seeds into the seed storage chamber 26, the inner lid 2
7 acts as a hindrance and prevents seeds from entering the fertilizer storage chamber 25. Further, when the lid body 21 is closed, the inner lid 27 is pressed by the lid body 21 and closed together against the elasticity of the spring member 33, and the inner lid 27 is locked by the locking means.

Note that the functions provided on the inner lid 27 and the fertilizer storage chamber 25 are similar to those described above.
