2. Description of the Related Art Recently, in a fertilizer application, which is an example of an apparatus for feeding out granular material for agriculture, side fertilizers for applying fast-acting fertilizer shallowly on the sides of planted seedlings, and deep middles between the inter-rows are used. Fertilizer with slow-acting fertilizer may be applied at the same time as deep fertilization.
In this so-called two-stage fertilization, different types of fertilizers are used at the same time as described above, and therefore, as a hopper structure for storing them, for example, one hopper is disclosed as disclosed in Japanese Patent Laid-Open No. 2-245101. It has a structure in which each storage chamber is divided into compartments and a lid which covers the upper opening of each storage chamber in common is provided.

[0003]

In the above hopper structure, when the lid is opened when replenishing fertilizer, the upper openings of the storage chambers, which are different fertilizer replenishing ports, are simultaneously opened. It will be. Therefore, the fertilizer that should be supplied to the target storage room may mix into the storage room for different types of fertilizer, and you can ensure that the target storage room does not mix into the other storage room while lifting the heavy fertilizer bag. Replenishment of fertilizer from the upper opening of the chamber required a great deal of care and labor, which was a cumbersome and uncertain task.

It is also conceivable to configure each storage chamber with individual hoppers and lids in order to reliably prevent the mixing of fertilizers, but the large number of hoppers makes the installation complicated and difficult to handle, and the cost is low. Also bulky. Moreover, the replenishment port for replenishing the fertilizer has the size of the upper opening of one storage chamber, making replenishment more difficult than that of the above publication.

The present invention has been made in view of such a situation, and by adding a simple and inexpensive improvement to the conventional hopper structure, it is easy and quick to replenish the agricultural powder and granules. , Is intended to ensure that it can be done.

[0006]

In order to achieve the above-mentioned object, the present invention divides one hopper for storing agricultural powder and granules to form a plurality of storage chambers, and at the same time A feeding mechanism is connected to each of the lower ends thereof, an outer lid is provided for commonly covering the upper openings of the storage chambers, and an inner lid is provided to individually open and close the upper openings of the storage chambers.

[0007]

According to the above construction, the size of the entire upper opening of the hopper when the outer lid is opened when replenishing the agricultural grain is aimed, that is, the size of the upper openings of the plurality of storage chambers combined. By opening only the inner lid of the intended storage chamber from the storage chambers that serve as the supply port of the storage chamber and are closed by the respective inner lids, there is no mixing into other storage chambers. In addition, since the outer lid is provided to prevent rainwater and the like from entering the hopper, the inner lid can have a simple structure having no function.

[0008]

As described above, according to the present invention, by adding a simple and inexpensive improvement to the conventional hopper structure, it becomes possible to easily, swiftly and surely replenish the agricultural powder and granules. .

Embodiments of the present invention will be described below with reference to the drawings. FIG. 4 shows a side surface of the seedling planting device 1 connected to the rear part of the traveling body of the riding type rice transplanter. The rear part of the seedling planting device 1 is equipped with a fertilizer application device 5 which is interlockingly connected via a linking mechanism 4 to a seedling planting mechanism 3 provided in pairs on the left and right sides of the rear part of the planting case 2. As shown in FIG.
The fertilizer applicator 5 is configured for two-stage fertilizer application, and the hopper 6 for storing fertilizer at the upper portion has left and right storage chambers A and A for storing the fast-acting fertilizer for side strips and a deep-layer fertilizer. In the central storage room B for storing the slow-acting fertilizer, the left and right partition walls 6a,
It is partitioned by 6a.

A fertilizer feeding mechanism 8 containing a feeding roll 7 is connected to the lower ends of the storage chambers A and B of the hopper 6 for storing the fertilizer, and the fertilizer feeding mechanism 8 is fed from the left and right fertilizer feeding mechanisms 8. The fertilizer is guided to the side-row grooving device 11 via the payout funnel 9 and the downflow hose 10, and is supplied to the shallow fertilization groove formed on the rice field by the grooving device 11. The slow-acting fertilizer fed from the central fertilizer feeding mechanism 8 is guided to the deep-layer fertilizer applying mechanism 12 via the feeding funnel 9 and the downflow hose 10, and is supplied deep into the rice field by the disc-shaped embedded disc 13. . The storage chambers A and B in the hopper 6 for storing the fertilizer are provided with inner lids 6A and 6B capable of individually opening and closing the respective upper openings, and by covering them in common, rainwater and the like can enter the hopper 6. Outer cover 6C
And are provided.

The case where each fertilizer is replenished in each of the storage chambers A and B will be described below. First, the outer lid 6C is removed and the entire upper opening of the hopper 6 is opened as a common replenishing port for each fertilizer. When replenishing the fast-acting fertilizer for the side strip, the central storage chamber B is closed by the inner lid 6B, and the left and right storage chambers A, A are detached by removing the inner lids 6A, 6A and replenished. To do. Next, when replenishing the slow-acting fertilizer for deep layers, the left and right storage chambers A, A are respectively covered with inner lids 6A, 6A.
A is closed, and the central storage chamber B is detached by removing the inner lid 6B and replenished in an open state. Further, the left and right inner lids 6A, 6A have inclined guide surfaces a, a directed toward the center, and the central inner lid 6B has an inclined guide surface directed outward so that the fertilizer can quickly flow to the storage chambers A, B. Surfaces b and b are formed respectively.

As shown in FIG. 2, the feeding roll 7 is a roll main body 7a fitted to the hexagonal feeding shaft 14 for inputting the planting rotational force of the seedling planting mechanism 3 through the linking mechanism 4 so that torque can be transmitted.
