DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agricultural hopper device which is mounted on a rice transplanter, a fertilizer applicator, a control device and the like to spray fertilizer and chemicals.

[0002]

2. Description of the Related Art The hopper lid of this kind of agricultural hopper is usually formed of a one-piece molded product of resin, and has a structure in which the hopper lid is openably and closably connected to a hopper on a main body side via a fulcrum shaft. For example, when the hopper lid is opened, the entire load of the lid is supported by, for example, a part of the lid which comes into contact with the hopper on the main body side.

[0003]

However, in the case of a one-piece molded article made of a resin, when an excessive external force is applied to the lid when the lid is opened due to insufficient strength of the opening / closing fulcrum of the lid, or the fertilizer in the hopper, However, there is a possibility that the medicine may be damaged when it comes to the lid. Also, when a load is applied to a part of the lid, the contact portion of the lid may be damaged.

[0004]

According to the present invention, there is provided an agricultural hopper device comprising a hopper lid which can be opened and closed on an upper part of a hopper for spraying fertilizer and chemicals on a field.
In the vicinity of the opening / closing fulcrum on the inner surface of the lid, a length approximately equal to the width of the lid is set.

It regulates the amount of opening, and when the hopper lid is fully opened,
Even if a load is applied in the opening direction, the lid
To support the load with the full width of the
By covering the gap with the main unit hopper with a hook,
Fertilizer overflows to the lid even when replenishing feed and chemicals
Sometimes, hooks prevent the dropping of fertilizer, etc.
To prevent the loss of materials and medicines and the adverse effects on
This is to prevent it.

[0005] Further, the hopper lid is provided with a transparent top plate and the top plate.
Combination structure with opening and closing fulcrum members to be joined to both left and right ends of the plate
The top plate can be used to check for fertilizers and chemicals in the hopper.

Reference numeral (50) denotes a branch pipe for connecting the feeding case (43) and the air tank (47), and forcibly feeds fertilizer at a feeding outlet in the feeding case (43) by blowing air from the tank (47). Is to be dropped and released.

As shown in FIGS. 1, 7 to 10, a hopper lid (51) provided above the fertilizer hopper (42)
Six hoppers (42) fixed in the lateral direction with connecting members (52) and bolts (52a) are provided so as to be covered by a single lid (51), and a center having a large left and right width is provided. A top plate (53), and a combination of an opening / closing fulcrum member (54) attached to the left and right ends of the top plate (53).
The top plate (53) is made of transparent acrylic, hard PVC, AS
(Acrylonitrile / styrene) resin or the like to make it easy to check the remaining amount of fertilizer in the hopper (42), and the fulcrum member (54) is opaque and has sufficient strength, elasticity and impact resistance. PA (polyamide)
POM (acetal), PP (polypropylene), PE
(Polyethylene) or the like to improve the support strength of the opening / closing fulcrum of the hopper lid (51) which is removably pivotally supported via the fulcrum shaft (55) on the left and right outermost walls of the hopper (42). It is configured as follows.

As shown in FIG. 9, the top plate (53) has a vertical edge (53a) obtained by bending the front end of the flat plate portion downward at a substantially right angle.
And the rear edge is bent downward in a curved shape (53
b), an L-shaped hook (56) having the same length as the width of the top plate (53) is integrally formed at a position near the curved edge (53b) on the inner surface of the top plate (53). 53) A plurality of laterally substantially parallel ribs (57) are formed integrally with the hooks (56) at appropriate intervals between the vertical edge (53a) of the inner surface and the hook (56) to improve the strength of the top plate (53). It is configured as shown. A notch (58) is formed in the hook (56) to avoid interference with the connecting member (52).

As shown in FIG. 10, the left and right fulcrum members (54) are formed in an L-shaped cross section when viewed from the rear, and the top plate (33)
An engagement groove (59) for inserting and connecting the left and right ends of the fulcrum member is formed at the horizontal end of the fulcrum member (54), and the fulcrum shaft (5) is formed.
5) Boss portion (54a) having fitting shaft hole (60)
Is formed integrally with the vertical inner surface of the fulcrum member (54), and attached to the upper rear end of the hopper (42) via the fulcrum shaft (55) so that the front side of the hopper lid (51) can be freely opened. I have. When the hopper lid (51) is fully opened, the hook (56) is brought into contact with the upper end of the inner surface on the rear side of the hopper (42) to restrict further opening, and the hopper (42)
The gap (K) formed in the rear side and the lid (51) is covered with the hook (56), and when the fertilizer is supplied to the hopper (42), even if the fertilizer overflows onto the lid (51), the gap is formed. (K) is configured to prevent falling.

In this embodiment, the hopper lid (51) is connected to the top plate (53) and the fulcrum member (5).
4) The top plate (53) is made of a transparent and relatively low-strength resin, and the fulcrum member (54)
Is made of opaque, strong, elastic and impact-resistant resin, making it easy to check the remaining amount of fertilizer in the hopper (42) and improving the strength of the support part of the lid (51). Hopper lids (5
1) is obtained.

The hook (56) provided on the inner surface of the top plate (53) of the hopper lid (51) reliably regulates the maximum opening amount of the lid (51), and at the time of replenishing fertilizer, etc. Even when the fertilizer overflows from the inside to the lid (51) side, the hook (56) prevents the fertilizer from spilling below the gap (K) between the hopper (42) and the lid (51), and Loss of fertilizer and adverse effects on peripheral devices due to fertilizer can be prevented.

Further, when the lid (51) is fully opened and a force is further applied in the opening direction, a portion of the lid (51) is not intensively loaded on the hopper (42) by the hook (51). By causing a load to be received over the entire width of 56), the lid (51) can be prevented from being damaged by dispersing the force.

FIG. 11 shows an example in which a hook (61) having a chin shape is provided on the inner surface of a top plate (53) in place of an L-shaped hook (56).
2), and when the hopper lid (51) is fully opened, the inner surface of the hook (61) is brought into contact with the upper end of the inner surface on the rear side of the hopper (42) as in the case of the hook (56) to restrict further opening. At the same time, the fertilizer is received on the upper surface (61a) of the hook in the shape of a zin with the opening directed downward, so that the fertilizer is prevented from falling from the gap (K).

In the above embodiment, the hopper (42)
Was used for fertilizer, but may be used as a chemical, or may be used for a hopper (42) such as a fertilizer other than a rice transplanter or a pest control machine.

[0021]

As is apparent from the above embodiments, the present invention relates to an agricultural hopper device comprising a hopper lid (51) which can be freely opened and closed above a hopper (42) for spraying fertilizer and chemicals on a field.
