CONSTITUTION:In a fertilizer applicator in which a roll 16 for quantitatively delivering a fertilizer in a hopper is interlocked with a motor 17, an automatic operating means 23 for measurement capable of driving and rotating the roll 16 by the set number of revolutions based on an instruction from an operating tool 22 for the measurement is installed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fertilizer application device for a rice transplanter in which a motor is interlocked with a roll for quantitatively feeding fertilizer in a hopper.

[0002]

2. Description of the Related Art Conventionally, in order to simplify the drive structure of a fertilizer application device, it has been considered to drive a roll that quantitatively feeds fertilizer in a hopper with a motor.

[0003]

However, the adjustment work for setting the supply amount of fertilizer in a predetermined manner is troublesome and likely to be inaccurate. In other words, in rice transplanters, it is necessary to adjust the fertilizer supply weight per machine mileage to a predetermined amount according to the distance between plants and the type of fertilizer.Therefore, every time the distance between plants and the type of fertilizer are changed, the roll It is necessary to confirm whether or not the actual fertilizer supply weight is adjusted to a predetermined amount while changing the size and the rotation speed of the fertilizer accommodating recess. However, when the roll is driven by a motor, in order to check whether the actual fertilizer feed weight has been adjusted to a predetermined amount, generally,
In addition to measuring the roll drive time, the fertilizer fed out during that time is collected and weighed, the fertilizer supply weight per hour is calculated, and the calculated value must be converted to the fertilizer supply weight per machine mileage for judgment. I have to measure the time,
Weighing, calculation and conversion are troublesome, and inaccurate due to measurement error or calculation error. The purpose of the present invention is to
The point is to make it possible to easily and accurately execute the adjustment work for setting the supply amount of fertilizer in a predetermined manner.

[0004]

A feature of the present invention is that in a fertilizer application device of a rice transplanter in which a motor is interlocked with a roll for quantitatively feeding out fertilizer in a hopper, the roll is operated based on an instruction from a measuring operation tool. There is provided an automatic measuring operation means for driving and rotating the machine for a set number of revolutions.

[0005]

[Effect] In other words, every time the distance between plants or the type of fertilizer is changed, it is possible to confirm whether or not the actual fertilizer supply weight has been adjusted to a predetermined amount while changing the size and rotation speed of the fertilizer receiving recess of the roll. When the weighing operation tool is operated, the roll is driven and rotated by the set number of rotations by the automatic weighing operation means, so the fertilizer fed during that time is collected and weighed, and the measured value is used as the fertilizer supply weight per machine travel distance. It suffices to convert and judge, the time measurement and the calculation of the fertilizer supply weight per hour, which were required in the above-mentioned conventional technology, can be eliminated and only the weighing and conversion can be performed. It is possible to easily and accurately carry out the adjustment work that is to be set.

[0006]

As a result, it has become possible to provide a fertilizer application device for a rice transplanter, which is further excellent in the function of adjusting the amount of fertilizer supply.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, in order to form a seedling planting device which is connected to a riding rice transplanter main body by a link device 1 so as to be able to move up and down, a seedling platform 2 which is reciprocally moved left and right with a constant stroke. , A large number of planting claws 3 for taking out and planting one seedling of one plant from the lower end of the seedling placing table 2, a grounding float 4 for supporting the seedling planting device and leveling the planting ground
And so on. The transmission case 6 is rotatably connected to the link device 1 by the boss portion 5, and the planting claw 3 is driven by the transmission mechanism in the transmission case 6 and the planting transmission case 7 which are interlocked with the power take-off shaft of the rice transplanter body. The seedling mounting table 2 is configured to be moved left and right by the reciprocating drive of the shaft 8 by the transmission mechanism in the transmission case 6. A vertical feeding device 9 is provided on the seedling placing table 2, and the vertical feeding device 9 is driven so that the seedlings are fed to the pick-up port side by a certain distance each time the seedling placing table 2 reaches the stroke end of the lateral movement. I am doing it. Support 1 for planting transmission case 7
0 is installed upright, the fertilizer application device 12 is provided on the support member 11 that is vertically slidably attached to the support column 10, and the support member 11 can be fixed to the support column 10 by the tightening fixture 13. A damper 14 is installed to prevent it from falling,
At the time of maintenance and inspection of the planting section, the fertilizer application device 12 is retracted upward so that the work can be easily performed. Fertilizer application 12
To form the fertilizer, a hopper 15 for storing the fertilizer, a roll 16 and a roll 1 for quantitatively feeding the fertilizer in the hopper 15.
Electric or hydraulic motor 17 interlocked with 6 and pipe 19 for dropping fertilizer from roll 16 into grooving device 18
Is provided, and the fertilizer is supplied into the fertilizer application groove formed in the field by the grooving device 18.

As shown in FIG. 3, a first sensor 20 for detecting that the machine is stopped, a second sensor 21 for detecting that the planting clutch is disengaged, and a fertilizer application device 12
A weighing operation device 22 is provided for each of the sensors 2
Based on the information from 0 and 21 and the instruction from the weighing operation tool 22, the motor 17 is automatically driven so that the roll 16 is driven to rotate by the set number of revolutions only when the machine is stopped and the planting clutch is disengaged. An automatic measuring operation means 23 for operation is provided so that the adjusting work for setting the supply amount of fertilizer to a predetermined value can be easily and accurately executed. In other words, each time you change the distance between plants or the type of fertilizer, roll 1
In order to check whether the actual fertilizer supply weight has been adjusted to a predetermined amount while changing the size and the rotation speed of the fertilizer accommodating concave portion of 6, the weighing operation tool 22 is operated with the machine and the seedling planting device stopped. Then, the roll 16 is driven and rotated by the set number of rotations by the automatic metering operation means 23, and the fertilizer fed out during that time is collected and weighed, and the measured value is converted into the fertilizer supply weight per machine travel distance for judgment. It is configured as follows.

[Other Embodiments] First and second sensors 21,
22 may be omitted. The weighing operation tool 22 and the automatic weighing operation means 23 may be provided in either the rice transplanter body or the seedling planting device. The structure and delivery capacity of the roll 16 can be appropriately selected, and the number of rotations of the roll by the automatic weighing operation means 23 can be set appropriately in accordance with the structure and delivery capacity of the roll 16. The specific structure of the fertilizer application device 12 and the type of rice transplanter to be attached are not limited.

It should be noted that reference numerals are added to the claims for convenience of comparison with the drawings, but the present invention is not limited to the structures of the accompanying drawings by the entry.
