Abstract

PURPOSE:To provide the subject apparatus having a specific construction and capable of preventing forgetting of the supply of fertilizer with an alarm device actuated if the fertilizer supply has been forgotten in case where transplantation is reopened after it is interrupted for resupplying the fertilizer on the occasion of its shortage. CONSTITUTION:At first, during transplantation, when a fertilizer in a fertilizer storage section decreases below a specified amount and an alarm device 110 is actuated, its action is stopped by pushing an alarm-stopping switch 114. Subsequently, the transplanter is driven beside a levee while the planting operation is continued and then the transplantation and the traveling of the machine body are stopped. By this ceasing treatment, the first releasing means 113 is actuated and an alarming-stopping command generated by the alarming-stopping switch 114 is canceled while the alarm device 110 is being stopped. After this, the fertilizer and seedlings are supplied. Subsequently, the machine body is started to travel and the transplantation is restarted and this resuming treatment actuates the second releasing means 113 to cancel the stop of the alarm device 110. By this, the alarm device 110 is actuated in case where the fertilizer supply has been forgotten.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fertilizer applicator used by being mounted on a rice transplanter.

[0002]

2. Description of the Related Art A fertilizer applicator used by being mounted on a rice transplanter is provided with an alarm device such as a buzzer for notifying an operator when the amount of fertilizer in a fertilizer storage unit falls below a certain amount. If the alarm sounds, the rice transplanter is moved to the edge while continuing the planting work, and fertilizer is replenished there, but it is noisy if the alarm keeps ringing while moving or during fertilizer replenishment. Usually, after recognizing that the alarm has sounded, the operator presses the manual alarm stop switch to stop the operation of the alarm.

[0003]

By the way, when the fertilizer is replenished at the edge of the ridge, the seedling is often replenished. Replenishment of seedlings is more frequent than replenishment of fertilizers, and work to stop the aircraft at the edge of the ridge is often seedlings replenishment work. I may forget In such cases, if conventional
Since the alarm stop switch kept the command to stop the alarm device operation, the alarm device did not sound even if the planting work was started. For this reason, the planting work was restarted without supplying fertilizer, resulting in a fertilizer-free section in which fertilization was not performed.

[0004]

The present invention has been made to prevent forgetting to replenish the fertilizer, and in order to achieve this, the fertilizer applicator is configured as follows. That is, the fertilizer applicator according to the present invention includes an alarm device that issues an alarm when the fertilizer in the fertilizer storage unit becomes less than a certain amount during planting work, and an alarm stop switch that stops the operation of the alarm device by manual operation. In the fertilizer application, due to the planting work stop operation, the first releasing means for releasing the alarm device stop command by the alarm stop switch in the state where the operation of the alarm device is stopped, and the planting work start operation And second release means for releasing the alarm device operation stop state.

[0005]

[Function] During planting work, the alarm device issues an alarm when the fertilizer in the fertilizer storage unit falls below a certain amount. After recognizing the alarm, the pilot pushes the alarm stop switch to stop the operation of the alarm. While continuing the planting work, the rice transplanter is moved to the edge. If the rice transplanter is moved to the edge, the planting work will be stopped and the aircraft will also be stopped. By stopping the planting work, the first releasing means is activated, and the alarm stop command by the alarm stop switch is released in the state where the operation of the alarm is stopped. Then, fertilizer supply and seedling supply are performed. After completing the fertilizer supply and the seedling supply, the aircraft will be started and the planting work will be started.
By starting the planting work, the second releasing means works,
The deactivation of the alarm is released. If fertilizer replenishment is completed, the alarm does not work, but if you forget to replenish fertilizer, the alarm will work.

When the engine is operated, warm air at the rear of the engine 30 is sent through the air chamber 84 into the fertilizer application conduits 82, ..., The fertilizer in the fertilizer application conduits 82 ,. … Keeps the inside dry and prevents the fertilizer from solidifying. The air chamber 84 is supported by the link base frame 50 and also serves as the frame of the fertilizer applicator 5.

During the planting work, if the fertilizer in the fertilizer storage section 80, ... Is exhausted, the work must be interrupted to replenish the fertilizer. Also, forget to switch on the blower 83,
If the planting operation is performed in a state where the blower 83 is not rotating, the fertilizer is not conveyed in the fertilizer application conduits 82, ... And the fertilizer is clogged in the feeding section 81. Therefore, an alarm device 110 such as a buzzer is provided to inform the operator that the fertilizer has run out and the blower 83 has not been turned on.

The alarm control circuit is constructed as shown in FIGS. In the figure, 111 is a fertilizer reduction switch, which is turned off when the fertilizer in the fertilizer storage units 80, ... A pressure sensitive switch 112 responds to the pressure in the air chamber 83 and is turned off when the blower 83 is operating and is turned on when the blower 83 is not operating. 113 is a clutch switch with a plant,
ON when the planting clutch is engaged, OFF when disengaged. Reference numeral 114 denotes an alarm stop switch which is turned on when the switch is pressed with a finger and turned off when the finger is released from the switch. Further, 115 is a relay, and when no current flows through the coil 115a, the relay switch 115b closes the contact on the alarm energizing circuit 116 side, and when current flows through the coil 115a, the relay switch 115b opens the contact on the holding circuit 117 side. close.

When the planting work is normally performed, the state is as shown in FIG. That is, the planting clutch switch 113 is ON, but the fertilizer reduction switch 111, ... And the pressure sensitive switch 112 are OFF, so the alarm device 110 is stopped.

When the amount of fertilizer in the fertilizer storage unit 80, ... becomes less than a certain amount during the planting work, the fertilizer reduction switch 111, ... Is turned on, current flows through the alarm energizing circuit 116, and the alarm 110 sounds. (Fig. 7). The alarm device 110 sounds even if only one of the fertilizer reduction switches 111 is turned on. After confirming that the alarm device 110 has sounded, the operator pushes the alarm stop switch 114. Then, a current flows through the coil 115a and the relay switch 115b is switched to the holding circuit 117 side, so that the operation of the alarm device 110 is stopped (FIG. 8). Since the holding circuit 117 remains closed even when the finger is released from the alarm stop switch 114, the relay switch 1
15b does not return to the alarm device energizing circuit 116 side. In this way, while the alarm stop switch 114 is pressed to stop the alarm device 110, the rice transplanter is moved to the edge while continuing the planting work.

When the rice transplanter has moved to the ridge, the planting clutch is disengaged to stop the planting work and the traveling is also stopped. By disengaging the planting clutch, the planting clutch switch 113 is turned off and the holding circuit 117 is opened. As a result, the relay switch 115a returns to the alarm device energizing circuit 116 side, and the alarm device operation stop command from the alarm stop switch 114 is released (FIG. 9). However, since the alarm energizing circuit 116 remains open at the part of the planted clutch switch 113, the alarm device 110 is deactivated and the alarm device deactivates. Fertilizer supply is performed in this stopped state. Usually, seedlings are supplied at the same time as fertilizers are supplied. During this replenishment work, it is noisy and uneconomical to keep the blower 83 rotating, so the blower 83 is stopped.

When fertilizer replenishment and seedling replenishment are completed, traveling and planting work are restarted. By inserting the planting clutch, the planting clutch switch 113 is turned on, the alarm energizing circuit 116 is closed, and the alarm unit deactivated state is released. If fertilizer replenishment is performed, since the fertilizer reduction switches 111, ... Are OFF, the alarm 110 does not sound even if the alarm deactivation state is released, but if fertilizer replenishment is forgotten, Decrease switch 111, ... is O
Since it remains N, the alarm device 110 sounds as soon as the planting clutch is inserted (FIG. 10). Further, even when the planting work is restarted without forgetting to turn on the switch of the blower 83, the alarm device 110 sounds by releasing the alarm device operation stop state (FIG. 11).

To summarize the operation of the alarm control circuit, the alarm stop command from the alarm stop switch 114 is released while the operation of the alarm 110 is stopped due to the stop operation of the planting work (first release). ) Together with the above, the alarm device operation stop state is released due to the planting work start operation (second release). As a result, when restarting planting work after fertilizer replenishment / seedling replenishment work, an alarm such as a buzzer sounds when the manure supply is forgotten or the blower switch is forgotten to notify the operator of the abnormality. In addition, after pressing the alarm stop switch 114 to stop the operation of the alarm device 110,
Even if you moved the rice transplanter to the edge, you forget that you need to replenish the fertilizer, and if you turn the aircraft and continue to plant the next planting line, When turning, the planting clutch is once disengaged, and then the planting clutch is re-engaged. Therefore, the first release and second release actions work and the alarm device 110 sounds. In the present embodiment, the first release and the second release are interlocked with the engagement and disengagement of the planting clutch, but they may be interlocked with other planting work stop operations and planting work start operations.

[0032]

As described above, the fertilizer applicator according to the present invention, when the planting work is restarted after the planting work is resumed after the planting work is suspended due to the fertilizer supply due to the fertilizer running out, The alarm activated to notify the operator that he had forgotten to replenish the fertilizer, so he could not accidentally plant with the fertilizer running out.
