Description

[Detailed description of the invention] [Industrial application field] The present invention provides an alarm device that is activated by detecting the cut state of the planting clutch and the consumption of seedlings, and also provides an alarm device that operates by turning on and off the operating circuit of this alarm device. This invention relates to a rear-mounted riding rice transplanter that is equipped with a switch.

[Conventional technology]

As an example of the conventional warning device for the rice transplanter mentioned above,
There was one shown in No. 58-68816.

[Problem that the invention attempts to solve]

In this conventional alarm system, it is possible to set the alarm system to a non-alarm state in which no alarms are issued using a manual operating tool. This non-alarm state is an operating state that is mainly used when the rice transplanter is running on the road, but when the rice transplanter is introduced into the rice field after running on the road, it is easy to forget to set the operating tool to the alarm-enabled state. There was room for improvement.

The present invention was developed in view of the above-mentioned circumstances, and it is possible to set the alarm device to a non-operating state while driving as before, and to detect the non-operating state of the alarm device when a rice transplanter is introduced into a rice field. The purpose is to provide a rice transplanter that can notify the

[Means for solving problems]

The present invention is characterized by providing an alarm mechanism to prevent forgetting to turn on the planting clutch, which operates only when the on/off detection sensor of the planting clutch is in the engaged state and the switch is in the alarm device activation circuit cut off state. The functions and effects are as follows.

[Effect]

As mentioned above, the notification mechanism is activated when the state of the on/off detection sensor of the planting clutch and the state of the switch of the operating circuit meet certain conditions, so when the machine is introduced into the rice field after driving on the road, If the switch is in the OFF state when the planting clutch is engaged, the notification mechanism is activated, and if the switch is in the ON state, the notification mechanism is not activated.

Also, if the switch is set to the ON state, an alarm will be issued in the conventional manner.

[Effect of idea]

Therefore, with a relatively simple configuration that includes an alarm mechanism that operates under certain conditions, it is possible to issue a conventional warning, and when the aircraft is introduced into a rice field after driving on the road, it can be used for planting seedlings. A rice transplanter with a simple structure has now been provided, which can immediately notify by operating an alarm mechanism if a switch of an operating circuit has been forgotten to be turned off at the start of work.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in FIG. 2, a driving unit A is installed at the front part of the traveling aircraft on which the steering front wheels 1 and the propulsion rear wheels 2 are mounted.
A tower riding driving section B is disposed in the center, and a seedling planting section C is connected to the rear end so that it can be driven up and down, thereby forming a rear-mounted riding rice transplanter.

As shown in FIG. 3, in this rice transplanter, one of the clutches 2a, 2a of the rear wheels 2 is disconnected, and by operating the steering handle 5, the turning angle of the front wheel 1 on the outside of the turn is adjusted so that the turning radius is as small as possible. The squaring operation system is configured so that the spooling is directed further toward the aircraft than the target turning center 0.

The driving section A is covered with a bonnet 3, and an alarm display section 4 is provided on the top surface of the bonnet 3. The driving section B is provided with a steering wheel 5, a seat 6, etc., and the seedling planting section C is provided with a steering wheel 5, a seat 6, etc. , a seedling stand 7 on which pine-shaped seedlings (not shown) are placed, six planting arms 8 . . . , three floats 9 . is attached so that it can be switched between an upright state and a lying down state, and a switch 11 is provided for each row on the top surface of the seedling stand 7 to detect when the number of remaining seedlings has fallen below a certain level. There is.

When turning the aircraft during seedling planting work, the seedling planting part C is raised, and at the end of the turn, the seedling planting part C is lowered and then the seedling planting work is resumed. There are times when work is restarted by forgetting to lower the attachment part C, and because it is a rear-mounted type, work may be performed without knowing that the seedlings have run out, and there are times when the line markers 10 and 10 are forgotten to be taken out. An alarm device D is provided to detect these and display them on the alarm display section 4.

That is, as shown in FIGS. 1 and 2, a transmission system to the seedling planting section C includes a planting clutch 12 that is operated to cut when the seedling planting section C is raised and to engage when it is lowered. A sensor 12a is attached to the clutch 12 to detect the operating state.

The switches 11 of the seedling table 7 are provided so as to be turned on when the seedlings are consumed and the upper end of the seedlings is below the position of the switch 11, and the set positions of the line markers 10, 10 are in the upright position. Switches 10a, 10a are provided to detect this if the condition is the same.

The sensor 12a and the switch 11...,1
0a, 10a, alarm display section 4, flicker circuit F,
An alarm device D is constituted by the main switch S, and the alarm display section 4 displays a lamp 13 that flashes when the planting clutch 12 is in the disconnected state (the operating position of the sensor 12a in the figure is in the (OFF) state), and a lamp 13 that blinks when the number of seedlings decreases. A lamp 14 that blinks and a lamp 15 that blinks when at least one of the line markers 10, 10 is forgotten to be set are provided.

By operating the main switch S to the side shown in the figure (ON), the alarm device D can be activated and the switch turns to the side shown in the figure (OFF).
Alarm device D will not operate if operated to the side.

This alarm device D has an alarm mechanism that detects when seedling planting work is started while the main switch S is turned off, that is, operated to the OFF side in the figure. E is added.

In other words, the notification mechanism E indicates that the planting clutch 12 is in the engaged state (the operating position of the switch in the figure is (ON)).
The switch S and the sensor 12a are connected to each other so that the switch S and the sensor 12a
It is composed of wiring lines 16, 17 and a buzzer 18.

Incidentally, Fig. 1 shows the status of each switch during normal seedling planting work.

[Another example]

In this embodiment, the buzzer 1 constitutes the notification mechanism E.
8 was used, but a lamp may be used instead, and wiring 19 is used as shown in FIG.
Further, by using the lamp 13 also, the buzzer 18 may be omitted.
