Description

[Detailed Description of the Invention] [Industrial field of application] The present invention provides a fertilizer application device including a hopper for storing powdered granular fertilizer and a feeding mechanism in a seedling planting device connected to the rear portion of a riding traveling vehicle body. It relates to a rice transplanter with a fertilizer application attached.

[Prior Art] In the rice transplanter described above, in the past, for example, the actual exploitation Sho 62-805
As disclosed in Japanese Patent No. 12, a lid that covers the upper opening of the hopper is openably and closably attached to the hopper, and the hopper is covered only with the lid.

[Problems to be solved by the invention]

The lid is designed to prevent water droplets such as rain from falling on the fertilizer stored inside the hopper, however, during the seedling planting work, the fertilizer inside the hopper may run out, In some cases, it is necessary to replenish the fertilizer in the middle of the paddy field. If it is raining at this time, it will rain until the lid is closed after the lid is opened and the fertilizer is replenished, and the fertilizer is clogged and the feeding mechanism is clogged. .

The present invention aims to prevent rainwater from falling on the fertilizer when the fertilizer is replenished.

[Means for solving problems]

A feature of the present invention is that in the rice transplanter with a fertilizer application having the structure described above, a cover member that can be retracted and attached is provided in a state of covering the upper side of the hopper and a state of being stored in the back of the hopper. , Its action and effect are as follows.

[Action]

When the fertilizer is replenished to the hopper during the seedling planting operation in rainy weather, it is possible to prevent rainwater from falling into the hopper when the fertilizer is replenished by extending the cover member above the hopper. Further, by storing the cover member during the planting work, there is no obstacle for the driver to monitor the seedling planting state.

[Effect of device]

As described above, according to the present invention, it is possible to prevent rainwater from falling on the fertilizer at the time of replenishing the fertilizer during rainy weather work without obstructing the view of the driver who monitors the situation of the seedling planting work.

〔Example〕

As shown in FIG. 1, at the rear part of the riding type vehicle (not shown), the seedling stand is attached to the link (3) which is driven up and down.
(4), seedling planting mechanism (5), a seedling planting device (A) equipped with a grounding float (6) is connected, and a hopper (7) for storing the granular fertilizer in this seedling planting device (A). ), Feeding mechanism (8), downflow pipe
(9), the fertilizer application device (B) equipped with the groove making machine (10) is attached to form a rice transplanter with a fertilizer application device.

The hopper (7) is made of a semi-transparent synthetic resin material so that the amount of fertilizer stored in the hopper (7) can be seen from the outside, and as shown in FIG.
1) is covered with an openable / closable lid (12).

This lid (12) is pivotally supported around the horizontal axis center via a hinge (13) on the upper side of the hopper (7) on the front side of the machine body, and in the vicinity of the pivot stop on the inner surface side, The flexible plate body (14) is fixed and the free end side of the plate body (14) is in contact with the inner surface of the hopper (7).

As shown in FIG. 3, the plate body (14) is configured to cover above the connecting portion by the hinges (13) in a state where the lid body (12) is opened, and fertilizer leaks from the connecting portion. It is prevented from falling down.

Further, an optical sensor (21) including a light emitting element and a light receiving element is provided on the inner surface of the hopper (7) on the lower side, and the hopper (7)
A means (not shown) is provided for notifying the driver of the traveling vehicle that the optical sensor (21) detects when the amount of fertilizer in the fertilizer is reduced to a predetermined amount or less.

Then, in the vicinity of the hopper (7), a plate-like cover member (15) that can be retracted and attached in a state of covering the upper side of the hopper (7) and a state of being stored in the back of the hopper (7) is attached. is there. In other words, the guide slots (16),
Support frames (17) and (17) having (16) are erected from the outer surface of the hopper (7), and headed pins (19) and (19) attached to the lower side of the cover member (15). 19) Both the support frame
It is inserted in the guide slots (16) and (16) of (17) and (17). or,
When the upper portions of the support frames (17) and (17) are bent in a substantially V shape and the cover member (15) moves upward, the upper portions of the hopper (7) can be covered by being guided in a substantially horizontal posture. The guide slots (16) at the end of the pins (19), (19)
Is formed with a recess (20) into which the hopper (7)
It is designed to be able to maintain the state of covering.

The cover member (15) has an effect of blocking rainwater when replenishing the fertilizer, and also has an effect of preventing the optical sensor (21) from malfunctioning due to sunlight by blocking sunlight during fine weather. To have.

[Another embodiment]

The cover member (15) may be formed of a cloth hood, or may be formed of an armored door in which a number of belt-shaped plate bodies are pivotally connected.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the structure of the accompanying drawings by the entry.

[Brief description of drawings]

The drawings show an embodiment of a rice transplanter with a fertilizer application device according to the present invention. Fig. 1 is a side view of a rear part of the rice transplanter, Fig. 2 is a side view of a main part, and Fig. 3 is a vertical side view of an upper part of a hopper. . (1) …… Traveling machine, (7) …… Hopper, (8) …… Feeding mechanism, (15) …… Cover member, (A) …… Seedling planting device, (B) …… Fertilizer.
