Description

[Detailed description of the invention] This invention relates to a lighting light for a rice transplanter. Specifically, the invention is a lighting light that can be used as a normal lighting light when the machine is running, but also indicates a decrease in the number of planted seedlings during seedling planting work. This invention relates to a lighting light in a rice transplanter that can also be used as a warning light.

Generally, the front side of the traveling body of a rice transplanter is equipped with a headlight that is turned on when driving at night when setting rice seedlings, or a light that indicates direction 1. Warning lights are installed to warn of a decrease in the number of planted seedlings, but conventionally, these lighting lights and warning lights have been installed separately, which has the disadvantage of requiring a large number of components and increasing costs. was.

The present invention was devised in view of the above-mentioned actual situation, and uses illumination lights such as headlamps installed on the traveling aircraft as a warning light to warn of a decrease in the number of planted seedlings during seedling planting work. A lighting device for a rice transplanter that allows the illumination light to double as a warning light, thereby eliminating the need to provide both separately as in the past, and thus saving parts and reducing costs. The purpose is to provide light.

The structure of the present invention will be explained with reference to an embodiment shown in the drawings. 1 is a traveling body of a riding rice transplanter, and a seedling planting device 2 is connected to the rear of the traveling body 1 via a link mechanism 3. It is constructed so that it can be raised and lowered freely.

A seat 4, a driving handle 5, an instrument panel 6 with instruments, etc. are provided on the center of the body frame 1a of the traveling body 1, and an engine is provided at the front of the body frame 1a. A bonnet 7 is provided which covers the parts and the like.

Reference numeral 8 denotes a headlamp provided on both left and right sides of the bonnet 7, and a support rod 9 of the headlamp 8 is fitted into the bonnet 7 so as to be freely inserted and removed, and is fitted into a stopper 10 fixed to the inner surface of the bonnet 7. It is inserted.

A stop pin 11 is implanted at the tip of the support rod 9, and the stop pin 11 is adapted to engage with a notch lea formed in the stopper 10.

Reference numeral 12 denotes a coil bullet, and the coil bullet 12 is inserted through the support rod 9 and interposed between the bonnet 7 and the headlight 8.

Then, by pushing the headlamp 8 into the bonnet 7 side and removing the stop pin 11 from the notch 110a, the headlamp 8 can freely rotate.
When engaged with a, the headlight 8 can direct and illuminate either the front or the rear of the traveling aircraft 1.

Reference numeral 13 denotes a seedling mounting table provided in the seedling planting device 2 and installed obliquely in a manner that is high in the front and low in the rear.
A limit switch 15 is provided on the seedling planting rod 14 side.

The limit switch 15 has a switch rod 15a that is supported so as to be able to freely appear and retract from a switch hole 13a formed in the seedling table 13. When there are no more planted seedlings, the switch rod 15a protrudes from the switch hole 13a and the switch 15 is turned on.

On the other hand, the instrument panel 6 always has a headlight 8 when driving at night.
a lighting switch 16 that turns on the light, and the seedling mounting table 1
Alarm switches 17 are provided which are connected to the limit switches 15 on the right and left sides of 3, respectively.

These headlights 8, limit switch 15, lighting switch 16, and alarm switch 17 are connected by a wiring diagram shown in FIG.

That is, when the alarm switch 17 is turned on during seedling planting work, if the number of planted seedlings on the right side of the seedling table 13 decreases, the right side headlight 8 will turn on, indicating that the number of planted seedlings on the left side will decrease. For example, the left headlight 8 is turned on.

In addition, in the figure, 13b is an auxiliary seedling mounting stand, 18 is a battery, 1
9 is a washer.

Moreover, the one in FIG. 7 shows another embodiment,
A cam 21 is fixed to the tip of the support rod 9 via a bolt 20, and an alarm switch 17a is arranged so as to be connected when the protrusion of the cam 21 comes into contact with the headlight 8.
When the alarm switch 17 is rotated to point rearward,
A switch is turned on.

Next, the operation of the present invention constructed as described above will be explained.

First, when driving at night, the lighting switch 1 is used to turn on the headlight 8 that illuminates the area ahead.
If 6 is set, the headlight 8 will illuminate the front as in the conventional case, allowing safe driving.

On the other hand, in order to use the headlights 8 as warning lights during seedling planting work, push the left and right headlights 8 into the bonnet 7 side, remove the stop pins 11 from the notched grooves 10a, and proceed as shown in step 1. By rotating the stop pin 11 by 80 degrees and engaging the notch groove 10a, the headlight 8 will be directed rearward.

Then, it is sufficient to turn on the left and right alarm switches 17.

That is, during seedling planting work, the number of planted seedlings on the seedling mounting table 13 decreases, and the switch rod 15 of the limit switch 15
When a protrudes from the switch hole 13a, the limit switch 15 is turned on and the headlight 8 is turned on, allowing the operator to know that the number of planted seedlings has decreased, and replenishing the number of planted seedlings from the auxiliary seedling table 13b. Measures can be taken such as:

Moreover, at this time, if the number of planted seedlings on the right side of the seedling table 13 decreases, the right side headlight 8 will turn on, and if the number of planted seedlings on the left side decreases, the left side headlight 8 will turn on. The operator can immediately know which seedling table 13 should be replenished, and can improve work efficiency.

Moreover, the warning lights for warning of a decrease in the number of planted seedlings are bright and large headlights 8 and are provided on both sides of the bonnet 7, making it easy for the operator to see and confirm.

On the other hand, in the one shown in FIG.
Since the switch 7a is turned on, it is convenient because there is no need to forget to turn on the switch.

4. In each of the above embodiments, the headlight 8 is used as a warning light, but this is not limiting. Any of them may be used, and examples of such devices include direction indicator lights, vehicle side lights, and the like.

In short, the present invention is a rice transplanter equipped with a traveling machine (seedling planting device), in which a lighting lamp provided on the traveling machine is rotatably supported so as to point in the front and back direction of the traveling machine. , the illumination light is connected to a detection switch that detects a decrease in the number of planted seedlings placed on the seedling mounting table of the seedling planting device, and is turned so that it points toward the rear of the traveling machine during seedling planting work. Since the system is configured so that the illuminated illumination lamp is used as a warning light to notify of a decrease in the number of planted seedlings, there is no need to provide a warning light separate from the illumination light as in the conventional system.
This has very useful practical effects, such as saving parts and reducing the size of the boss, and improving work efficiency.
