Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a vegetable transplanter for continuously planting vegetable seedlings such as cabbage in a field.

[0002]

[Problems to be Solved by the Invention] Conventionally, the upper surface of the ridge for planting vegetable seedlings is covered with a mulch film, and the seedling planting portion of the mulch film is incised with a multi-cut heater.
Vegetable seedlings were planted in the incisions with the planting claws, but since the multi-cut heater becomes hot, when the vegetable seedlings are supplied to the seedling mounting table or after the planting work, the aircraft is stopped near dead grass etc. , There is a problem such as burning dead grass due to the heat of the multi-cut heater.

[0003]

[Means for Solving the Problems] Therefore, according to the present invention, a seedling tray containing vegetable seedlings is mounted on a seedling mounting table, and the seedling mounting table is reciprocally moved from side to side so that vegetable seedlings can be applied to a field scene by a planting claw. In a vegetable transplanter equipped with a multi-cut heater that automatically plantes and cuts the seedling planting part of the multi-film that covers the ridges, the multi-cut heater detects the rotation of the axle that drives the running wheels and stops when the axle stops. The high temperature alarm of the multi-cut heater is turned on and off by detecting the rotation of the axle, so the high temperature alarm of the multi-cut heater is stopped during the planting work when the axle is rotating. , For example, in a vegetable seedling replenishment work in which the traveling clutch is engaged and the traveling speed is set to neutral, the high temperature warning of the multi-cut heater is issued by stopping the axle, Obtained to prevent the problem such as burning the dried grass near occurs due Tohita heat in advance, it is what could strive to facilitate handling optimization of multi-cut heater.

3) is provided, the high temperature alarm of the multi-cut heater (17) is turned on and off by detecting the rotation of the axle (70). Therefore, the multi-cut heater (17) is turned on during the planting work in which the axle (70) is rotating. When the high temperature alarm is stopped, for example, when the traveling clutch (75) is in the engaged state and the traveling transmission main shift lever (22) is in a neutral state, the high temperature of the multi-cut heater (17) is stopped by stopping the axle (70). An alarm is issued and the multi-cut heater (1
It is configured to prevent the occurrence of problems such as burning of dead grass around by the heat of 7).

Then, as shown in the flow chart of FIG. 6, the temperature of the multi-cut heater (17) is set (4
(0 to 50 degrees) or higher, or even when the heater (17) temperature is lower than the set temperature and the power of the multi-cut heater is turned on by turning on the heater switch (69), the rear wheel (4) is An obstacle such as dead grass or an operator, which is stopped and the axle (70) is detected by the rotation sensor (71) and detected by the ultrasonic sensor (68), is approaching the multi-cut heater (17). At this time, the buzzer (73) is sounded to give an alarm. During the work of planting vegetable seedlings, the axle (70) is rotating even if the temperature of the heater (17) is high.
Is kept off and no alarm is issued.

When the vehicle body is turned in the field headland by detecting the rotation of one of the left and right rear wheels (4) and (4), one of the axles (70) is turned off by the side clutch disengagement. ) Stops and sounds the buzzer (73), the alarm operation check of the buzzer (73) can be performed by this sounding. Also, by detecting the rotation of both axles (70) (70) of the left and right rear wheels (4) (4), the buzzer (73) is prevented from ringing when the aircraft is turned around in the field headland. The alarm of the buzzer (73) can be issued only when the aircraft is stopped at a certain place such as when the transplanting work is completed or when the seedling mounting table (14) is replenished with preliminary vegetable seedlings.
