Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sighting device for a rice transplanter, and more particularly to a sighting device for aiming at a traveling reference line of a rice transplanter.

[Conventional technology]

With conventional rice transplanters, a sighting device is attached to the center of the front of the machine, and by driving this sighting device in line with a running reference line drawn on the rice field in advance, the spacing between rows for planting seedlings can be adjusted appropriately. There is also a rice transplanter that maintains good straightness.

[Problem that the invention attempts to solve]

This sight usually protrudes forward or upward from the body of the rice transplanter, and has the disadvantage of being damaged by contact with other objects, or getting in the way when the machine is being driven on the road or stored. .

[Means for solving problems]

Therefore, in the present invention, a sight whose base is pivotally mounted inside the hood of the aircraft and projects outward from the bonnet is provided so as to be able to rotate in the front and back direction. When approaching the outer surface and rotating forward to protrude outside the bonnet, the height of the tip of the sight will be lower than during the rotation, and the intermediate part will be bent so that it is in an upright position. It is characterized by:

[Effect]

By configuring as described above, the present invention has the following features:
The rice transplanter can be operated accurately along the travel reference line, and when stored, it does not protrude significantly from the machine body, does not come into contact with other objects and get damaged or get in the way, and has a large This prevents mud from becoming hard and causing poor rotation.

〔Example〕

Embodiments of the present invention will be specifically described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a four-wheeled riding vehicle, at the rear of which a rice transplanting machine 3 is lifted and lowered via a lift mechanism 2 consisting of a parallel link and a hydraulic cylinder (not shown) that moves the parallel link up and down. It is possible to install the rice transplanter and constitute a well-known rice transplanter.

The rice transplanting machine 3, like the conventionally known one, has a frame 4 that also serves as a transmission case as a base, a float 5 disposed below the frame 4, and a float 5 that is tilted toward the traveling vehicle body 1 and reciprocates in the left-right direction. The seedling tank 6 has a seedling tank 6 supported as shown in FIG. The pine-shaped seedlings are taken out one by one from a seedling outlet and planted on the rice field.

An engine 8 is mounted on the front part of the traveling vehicle body 1, and the upper side of the engine 8 is covered with a bonnet 9. This bonnet 9, as shown in FIG.
A hinge 11 is screwed onto the tip of a lower cover 10 that covers the lower side of the engine room, and it can be rotated between a position that covers the engine 8 and an open position that opens toward the front of the aircraft to open the engine room. It is becoming.

In this engine room, the base end of the sight 12 is pivotably supported in the front and rear direction by a pin 13 supported on the front side wall in the bonnet 9, and the distal end thereof It protrudes outward from a slit 9a vertically provided in the front side wall of the bonnet 9, rotates rearward, and bends along the outer surface of the bonnet 9 when in the stored state. A rearwardly projecting bracket 14 is fixed to the pivot point of the sight 12 and the pin 13, and a toggle spring 15 is stretched between the bracket 14 and the bonnet 9. And the sight 12 is
When the rice transplanter is rotated forward around the pin 13 to protrude in front of the rice transplanter and put into use, the height of the tip of the sight 12 is lower than during rotation and is in an upright position. The middle part is 2 in the front and back direction.
The toggle spring 15 is bent in stages, and when the toggle spring 15 is in the used state and the unused state, that is, in the stored state, the toggle spring 15 acts as a toggle when it passes the pin 13 position, and is fixed at the respective position. ing. Further, the range of rotation of the marker 12 between the use position and the non-use position is regulated by both ends of the slit 9a acting as stoppers.

In such a configuration, when the rice transplanter is introduced into a rice field and rice transplanting work is performed, the sighting device 12 is first turned to the use state, and then the worker sitting in the driver's seat 1a places the sighting device 12 on the rice field in advance. The steering handle 1b is operated so that the rice transplanter runs in accordance with the drawn running reference line. This allows the sight 1
2 is in an upright position near the soil surface at the front of the machine, so the rice transplanter can be reliably run along the running reference line, and the seedlings planted by the rice transplanter 3 can be planted with appropriate distance between the rows. In addition, rice transplanting work is carried out in an orderly manner by maintaining the straightness of the rice transplanter. Also, when storing the sight 12, the bonnet 9
It is easy to store as it can be stored along the outer surface of the bonnet, and its pivot point is set inside the bonnet 9, so there is less chance of muddy water splashing on it and its rotation becomes poor. can be avoided.

In addition, when the rice transplanter is not performing planting work, that is, when traveling on the road or storing in a storage shed, the sight 12 can be stored in an unused position, so that the pivot position of the sight 12 can be adjusted. Since it is located inside the bonnet 9 and also along the outer surface of the bonnet 9, the overall length of the aircraft body is shortened and it is difficult to come into contact with other objects, thereby preventing damage accidents.

Further, when opening and closing the bonnet 9, by keeping the sight 12 in the unused position, it moves together with the bonnet 9, so there is no problem.

[Effect of idea]

As explained above, according to the sighting device of the rice transplanter according to the present invention, since it is configured as described above, the sighting device is oriented toward the soil surface at the front of the machine during work, and is in an upright position. The rice transplanter can be operated accurately along the travel reference line, and when stored, it can be stored at about the height of the bonnet, making it easy to store.
Because the pivot point is located inside the bonnet,
The overall length of the fuselage can be shortened, reducing the amount of muddy water on the pivot parts and impairing rotation performance, and also preventing accidents such as damage from colliding with other objects when not in use. can do.
