Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an agricultural powder or granular material spraying device which is installed in a rice transplanter or the like and sprays agricultural powder or granular material such as fertilizer or seeds to a field.

[Prior Art] In a rice transplanter, which is one of the paddy field working machines, for example
As disclosed in Japanese Patent No. 21708, two sets of groovers for digging two kinds of grooves having different depths are provided, and agricultural powder and granules are dispersed from one feeding mechanism such that hoses are installed on both groovers. Some are equipped with devices.

This will allow you to plant seedlings and spray fertilizer into deep trenches at the same time, spray seeds into shallow trenches without planting seedlings, or in shallow trenches. At the same time that seeds are sprayed, fertilizer can be sprayed in deep grooves, but in order to use the above work patterns properly, a partition plate is installed in the tank connected to the upper part of the feeding mechanism. Thus, the agricultural powder and granules contained in one section of the tank are fed into the shallow groove, and the agricultural powder and granules contained in the other section are fed into the deep groove.

[Problems to be solved by the device]

With the above-mentioned structure, the tank capacity can be fully used in the case of work in which two or one type of agricultural granular material is simultaneously sent to both the shallow groove and the deep groove, but only one groove can be used for agricultural purposes. In the case of work such as feeding powders, only half the tank capacity can be used. In other words, the agricultural powder and granules must be placed in only one section of the tank and the other section must be empty.

Here, the present invention focuses on the above-mentioned problem, and aims to make it possible to use the entire tank capacity even in the operation of feeding the agricultural grain or granular material to only one groove.

[Means for Solving the Problems]

The feature of the present invention resides in that the agricultural powder-dispersing device is configured as follows.

That is, the first and second groovers for digging two types of grooves having different depths are provided in the field, and a hose is erected from each of the first feeding mechanism to each of the first and second groovers, and the feeding is performed. Agricultural powder fed from the mechanism is supplied to one of the first and second groovers, and to both the first and second groovers. A switchable shutter mechanism is provided on the lower side of the feeding mechanism, and its action and effect are as follows.

[Action]

With the above-mentioned structure, all of the agricultural granules fed from the tank through the feeding mechanism by the switching operation of the shutter mechanism can be sent to one of the groovers, so that only one groove can be used for agriculture. Even when the powder or granular material is fed, it is not necessary to provide a partition plate in the tank, and the entire capacity in the tank can be used.

[Effect of device]

Therefore, even when the agricultural powder or granules are fed into only one of the grooves, the tank can be filled with one type of agricultural powder or granules to perform the work, and the work efficiency is improved. Further, since the agricultural powder particles can be fed into both the grooves while the tank is filled with the agricultural powder particles, the function of the conventional structure is not impaired.

〔Example〕

Hereinafter, a riding type rice transplanter equipped with a fertilizer application, which is one of the embodiments of the present invention, will be described with reference to the drawings.

As shown in Fig. 1, the planting arm (2) is rotated at the rear of the planting mission (1), and the seedling stand (4) is slidably driven on the guide rail (3) of the planting mission (1). ) And the like constitute a seedling planting device, and this seedling planting device is vertically movably connected to the machine body (not shown) via a four-link mechanism (5).

The seedling planting device is equipped with a fertilizer application device as an agricultural powder and granular material spraying device, and this fertilizer application device is a fertilizer storage tank (7), as shown in the same figure, and the fertilizer in the tank (7) is intermittently supplied. It is composed of a feeding mechanism (9) having a feeding roll (8) which is fed to the inside, and the like. The delivery mechanism (9) and the delivery roll (8) will be described in detail. As shown in FIGS. 1 and 3, a drive shaft (10) having a hexagonal cross section is rotated in the lateral direction of the body of the delivery mechanism (9). The drive shaft (10) is provided with a pay-out roll (8) while being horizontally mounted freely. Furthermore, the link mechanism (11) that repeatedly drives the planting arm (2) up and down and the arm (1
2) The linking rod (13) is installed between the drive shaft (10) and the feeding roll (8) around the horizontal axis (P ₁ ) in conjunction with the planting operation of the planting arm (2). The fertilizer, which is driven by reciprocal reciprocation, enters the concave portion (8a) provided on the outer periphery of the feeding roll (8) and is fed alternately to both sides so as to be scraped off by the brush (14).

On the other hand, as shown in FIG. 1 and FIG.
(6) The first groover (15a) that digs two types of grooves with different depths.
The second groove making device (15b) is attached via the groove cutting plate (16), and the funnel mechanism (9) is connected at its lower portion with a funnel portion (17) which is symmetrical in the longitudinal direction in a side view. (17)
From the first to the second and third groove makers (15a) and (15b), the hose (18)
Is erected. Further, the funnel portion (17)
A shutter member (19) made of hard rubber is supported in the inside so as to be swingable around the horizontal axis (P ₂ ), and a handle (20) for swinging the shutter member (19) from the outside is provided. Has been.

With the above structure, the shutter member (19) is set in the first position (A).
The fertilizer from the feeding mechanism (9) can be sent to the side of the first grooving device (15a) that digs a shallow groove by setting the above, and by setting the shutter member (19) to the second position (B) Can be sent to the side of the second grooving device (15b) for digging a deep groove. Further, as shown in FIG. 5, a partition plate (21) is provided in the tank (7), different kinds of agricultural powder and granules are put in the partitioned front and rear chambers, and the shutter member (19) is at a neutral position. When fixed by, both agricultural powder particles from the feeding mechanism (9) are simultaneously sent to each of the first grooving device (15a) side and the second grooving device (15b) side.

Further, as shown in FIG. 4, the grooved plate (16) is attached to the float (6) through the rubber member (22) and the spring (23), and the grooved plate (16) has an electric vibrator ( 24) is attached, and the grooving plate (16) and the first and second groovers (1
