Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fertilizer storage hopper used for a fertilizer such as a rice transplanter with a fertilizer which sprays fertilizer simultaneously with planting of seedlings. 2. Description of the Related Art Conventionally, a lid for closing an upper opening of a fertilizer storage hopper is pivotally connected to a container body so as to be swingable and openable. [0003] This type of fertilizer storage hopper in which the upper opening of the container body is covered with a swingable openable and closable lid accommodates the lid when the lid is opened. Fertilizer can be replenished while being attached to the vessel body. Therefore, compared to the type of fertilizer storage hopper using a removable lid, such as when replenishing fertilizer in the field, after temporarily placing the open lid in a place on the fuselage out of the way, It is advantageous in terms of storage of the lid, since it is possible to omit the trouble of having to replenish the fertilizer and take out the lid again and close the lid, which is advantageous in terms of storage of the lid. Because you can not remove the body, when replenishing fertilizer,
There is a problem that it is difficult to transfer the fertilizer overflowing from the inner surface of the lid to the container body after replenishing the fertilizer. Therefore, as means for solving the above-mentioned drawbacks,
It is conceivable to remove the lid and transfer it when transferring the fertilizer overflowing from the inner surface of the lid to the container body by configuring the pivot pin of the lid that can swing open and close freely. In such a case, insertion and removal of the pivot pin become troublesome. A sealing material is adhered to the inside of an opening / closing pivot for pivotally opening and closing the lid with respect to the container body of the hopper so that the lid can be opened and closed. By preventing the fertilizer from leaking out, even if the fertilizer overflows on the inner surface side of the lid, it is impossible to imagine that the fertilizer can be transferred into the container body again by the closing operation of the lid. However, in this case, each time the lid is swung open and closed, the sealing material of the opening and closing pivot portion is greatly deformed, and thus there is a problem in the durability of the sealing material. The present invention provides a fertilizer storage bopper that can easily transfer the fertilizer overflowing from the inner surface of the lid to the container body without troublesome work such as attaching and detaching the lid. It is intended to be provided by. In order to achieve the above object, the present invention is characterized in that the upper opening of the container body is covered with a lid which can swing open and close around the opening and closing pivot. In the fertilizer storage hopper, one end is fixed to the inner surface of the lid so as to cover the opening / closing pivot from above, with the lid in an open position, and the other end is loosened. The point is that a flexible cover body as an end is provided. The operation of the above technical means is as follows. When the lid is opened, the opening / closing pivot is covered with the cover, so that the fertilizer overflowing from the inner surface of the lid does not leak out from the gap between the lid and the container body. And
When the fertilizer on the inner surface of the lid is transferred to the container body side, the cover covering the opening and closing pivot of the lid serves as a guide chute as the lid is closed, and the overflowing fertilizer is removed from the lid side. From the container to the container body side. In addition, the cover body has one end side fixed to the inner surface side of the lid body and the other end side as a free end. It will work in conjunction. At this time, since the other end of the cover is a free end, the other end is allowed to move while following the movement of the one end due to the swing of the lid. The lid can be opened and closed without causing a large deformation corresponding to a change in the relative attitude between the lid and the container body. Further, since the cover body is flexible, for example, as in the case where the cover body is formed of a rigid member, with the swinging of the lid body, the fertilizer causes the container body and the cover body to move. When it is caught in between, there is no danger that the lid and the container body will be damaged by forcibly opening and closing the lid. As a result of the above construction, as a result of the closing operation of the lid, the fertilizer overflowing on the inner surface of the lid can be prevented from leaking out of the gap between the lid and the container main body. Can be easily transferred to the side, and the transfer work of the leaked fertilizer accompanying the replenishment of the fertilizer becomes easy. Also, the degree of deformation of the cover body is small in spite of the large opening and closing operation of the lid body, and the durability of the cover body can be improved. Further, since the cover body is flexible, there is little possibility that the cover body and the container body are damaged by the fertilizer being pinched, and this is also useful for improving the durability. [0010] As shown in FIG. 1, a seedling rest 4, a seedling planting mechanism 5, and a ground float 6 are attached to a link 3 which is driven up and down at the rear of a riding type traveling machine (not shown). And a fertilizer applicator B equipped with a hopper for storing powdery and granular fertilizer, a feed-out mechanism 8, a downflow pipe 9, and a channel generator 10 attached to the seedling transplanter A provided. A rice transplanter is configured. The hopper has a container body 7 made of a translucent synthetic resin material so that the amount of fertilizer stored in the hopper can be visually checked from the outside, and as shown in FIG. The upper opening 11 is constituted by a lid 12 which can be swingably opened and closed. The lid 12 is provided on the container body 7 on the front side of the fuselage.
A hinge 13 as an opening / closing pivot is pivotally supported on the upper side of the side surface so as to be swingable about the axis of the horizontal axis, and a flexible plate 14 as a cover body is provided near a pivot stop on the inner surface thereof. In addition to being fixed, the free end side of the plate 14 is provided in a state of contacting the inner surface of the container body 7. As shown in FIG. 3, the plate 14 is configured to cover the upper part of the connecting part by the hinge 13 when the lid 12 is opened, and to prevent the fertilizer from leaking from the connecting part. Prevented. On the lower inner surface of the hopper 7,
An optical sensor 21 including a light emitting element and a light receiving element is provided, and when the amount of fertilizer inside the hopper 7 decreases to a predetermined amount or less, the optical sensor 21 senses this fact and notifies a driver operating the traveling body (FIG. (Not shown). A plate-like cover member 15 is provided near the hopper 7 so as to be able to move back and forth between a state of covering the upper part of the hopper 7 and a state of being housed in the back of the hopper 7. That is, support frames 17, 17 having vertically long guide slots 16, formed on both left and right ends of the hopper 7, are erected from the outer surface of the hopper 7, and are attached to the lower side of the cover member 15. The pins 19, 19 are inserted into the guide slots 16, 16 of the support frames 17, 17 respectively. When the upper portions of the support frames 17, 17 are bent in a substantially rectangular shape and the cover member 15 moves upward,
It is configured to be guided in a substantially horizontal posture and to cover the upper part of the hopper 7, and the pin 1
Engagement recesses 20 for engaging the hoppers 9 and 19 are formed so that the hopper 7 can be kept covered. The cover member 15 has an effect of blocking rainwater when replenishing fertilizer, and also has an effect of blocking sunlight in fine weather to prevent the optical sensor 21 from malfunctioning due to sunlight. It is.
