Description

Detailed Description of the Invention (Industrial Field of Application) This invention is used in fertilizer applicators and seeding machines6 (Prior Art) One that displays the number of discharges ≠ (Japanese Patent Application Laid-Open No. 61-139431O), and one that operates a separate motor to increase the number of discharges of each 5I unit installed in the powder supply device. (Japanese Unexamined Patent Publication No. 62-6605) has been proposed.

(Object of the invention) The present invention automatically operates the feeding amount adjusting device provided in each of a plurality of powder supply devices with a single motor,
This aims to streamline the configuration.

(Means for Achieving the Object) In order to achieve the above object, the present invention provides a plurality of powder supply devices 4, each of which is provided with a feeding amount adjusting device 14, and a powder supply device 4. It is equipped with respective sensors 28 that measure the amount of powder and granular material being fed out, a single motor 21 that operates a plurality of feeding amount adjustment devices W14, and a control device 32 that operates the motors based on information from the sensors. Device 3
Reference numeral 2 refers to a powder or granular material characterized in that, when the average value or the sum total of the powder or granular material measured by each sensor 28 exceeds a set value limit, the motor 21 is operated to adjust the amount of delivery. It was used as a feeding amount adjustment device for the feeder.

(Function) Since the present invention is configured as described above, the plurality of granular material supply devices (fertilizers or seeding devices) 4 feed out the granular material (fertilizer or seeds), and the fertilization or sowing operation of multiple rows is performed. It is carried out. The amount of powder and granular material fed out from each of the powder and granular material supply devices 4 is measured by each sensor 28, and the result is transmitted to the control device 32. Here.

When the average value or the sum of the feeding amounts measured by each sensor 28 exceeds the set value limit, the control device 30 commands the motor 21 to rotate forward or reverse.

All of the delivery amount adjusting devices 14 operate to increase or decrease the delivery amount, and adjust the average value or sum of the delivery amounts to within a set value range.

In addition, it may be configured to display the measured value of the feeding amount by each sensor on a monitor, or to issue an alarm when the difference between the measured values of each sensor exceeds a certain limit, so that each feeding amount adjusting device 14 can be operated independently. (Effect) As described above, according to the present invention, a plurality of powder supply bags W
Since each of the feeding amount adjusting devices 14 provided in the feeding amount adjusting device 4 is automatically adjusted by a single motor 21, the construction is simple and significantly streamlined.

(Example) The present invention will now be described in detail.

As shown in FIG. 1, a seedling planting device 3 is connected to the rear of the traveling vehicle body 1 with a link 2, and a fertilizing device (powder supply device) 4 is attached to this seedling planting device 3. It is a seedling transplanter (powder feeder) that propels the paddy field with 6 rotations, transplanting seedlings and spreading fertilizer at the same time.

The seedling planting device 3 includes a gear box 7 in the center, a seedling platform 8 that is tilted forward and moves from side to side, and a lower end of the seedling platform 8 that rotates from top to bottom. Seedling rod 9 and gear box 7
It consists of a float 10 that is installed under the float and slides on the mud surface.

The fertilizer application device 4 is attached to the gear box 7 after the seedling stand 8. As shown in FIG. 2, a plurality of seedling planting devices W3 are provided side by side so as to correspond to the number of rows of seedlings to be transplanted in one process.

Each fertilizer application device 4 is configured as follows.

That is, as shown in FIG. 3, a rotor 13 rotated by a horizontal shaft 12 is provided below the tank 1 for storing fertilizer, and the fertilizer is delivered through a groove 13a on the outer periphery of the rotor 13. This rotor 13 is equipped with a delivery amount adjusting device 14, and adjusts the amount of fertilizer delivered by changing the width of the groove 13a as follows.

A male screw 15 extends to the right from the side of the rotor 13 so as to cover the horizontal shaft 12, and is screwed into the center of the slider 6. This mover 16 includes a protrusion 16a that enters the groove 13a from the right, and when the male screw 15 turns, it moves in the axial direction due to the engagement of the screw, and the protrusion 16a moves left and right within the groove 13a. The male screw 15 protrudes from the machine wall at the right end, and the spline of a gear 17 with a knob 1.7a engages with the spline 1.5a at the end. The gear 17 has a ring-shaped groove 17b on the left end, and a leaf spring 18 extending from the machine wall is attached to the ring-shaped groove 17b.
When the lower end of the gear 17 is engaged and the knob 17a is pulled to the right, the gear 17 deforms the leaf spring 18 and moves.

The adjustment shaft 19 is supported laterally, and as shown in FIG. 2, it meshes with a gear 20 at the left end or a gear 22 of a motor 21, and a plurality of gears 23 fixed in the middle mesh with the gears 17 of each fertilizer application device 4. ing.

Therefore, when the motor 21 rotates, each gear 23
rotates each gear 17, and the pheasant screw 15 rotates the mover 1.
6 is moved laterally, and its protrusion 16a slides within the groove 1.3a, thereby simultaneously changing the active state of the groove 13a. Note that when the motor 21 is stopped, the desired knob 17a is pulled to the right to separate the gear 17 from the gear 23, and the knob 17a is turned by hand. Then, this knob 17a
The male screw 15 rotates with the rotation of the rotor 13, and the movable member 16 is moved, so that only the effective state of the groove 13a of the rotor 13 can be changed.

The horizontal shaft 12 is a single shaft common to each rotor 13, and as shown in FIG. 2, a lever 24 with a ratchet is provided at the center thereof. The tip of an arm (not shown) rotating at the rear end of the gear box 7 and the tip of this lever 24 are connected by a rod 26, so that the horizontal shaft 12 is intermittently rotated by rotation of the arm. .

A plurality of hoppers 27 are independently provided under each rotor 13, and a sensor 28 for measuring the amount of fertilizer passing through the pipe portion 2'7a is provided.

As shown in FIGS. 1 and 4, the same number of groove makers 29 as the rotors 13 are attached to the float 10 beside each seedling planting rod 9. A boot 30 is attached to the groove cutter 29 so as to cover it.

This boot 30 is integrally made of a bellows-type extensible part 30a, a pipe 30b whose lower end extends to the groove cutter 29, and a relatively soft comb, into which the lower end of the hose 31 extending from each pipe part 27.1 is inserted. It's included. The groove part at the upper end is attached to the gear box 7, and when the float 10 rotates around the shaft at the rear end as it slides on the mud surface, the extendable part 30a expands and contracts to accommodate this. There is.

As shown in FIG. 5, each sensor 28 is connected to the controller 32.
In addition to sending information from the computer, setting values can be input 33. This control device compares the average value of the fertilizer flow rate obtained from each sensor 28 with the input set value, and the average value is determined as the permissible range (limit) of the set value.
When it exceeds this, the motor 21 is rotated forward, and when it falls below,
The motor 21 is connected to rotate the motor 21 in the reverse direction. Furthermore, if the difference between the measured values of the respective sensors 28 exceeds a certain value, a buzzer 34 or a lamp is configured to issue an alarm.

Note that the motor 21 can be operated using the sum of the fertilizer flow rates measured by the respective sensors 28 instead of using the above-mentioned average value. In addition, a means for displaying the flow rate of fertilizer measured by each sensor 28 on a monitor may be added.
