JPH08140443A - Fertilizer applicator in transplanter for sugar cane seedling - Google Patents

Abstract

PURPOSE: To provide a fertilizer applicator for sugar cane seedling transplanter which can forcibly feed the fertilizer to the outlet at the tank bottom and scatter it from the outlet through the scattering tube, when seedlings of sugar cane is transplanted with cost reduction improved. CONSTITUTION: The driving machine body for a sugar cane seedling transplanter is equipped with the tank 21 and the fertilizer-scattering pipe 24 so that the outlet 22 at the bottom of the tank 21 is connected to the top end of the scattering pipe 24 and the bottom end of the pipe 24 is positioned immediate over the nursery. The screw 23 is set at the bottom of the tank 21 for transporting the fertilizer or agrochemicals to the outlet 24 so that the screw 23 may be driven by a mechanism interlocked with the running of the machine body.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for automatically applying fertilizers and chemicals when automatically planting sugar cane seedlings.

[0002]

2. Description of the Related Art Planting sugar cane seedlings manually requires a great deal of work and makes it difficult to secure a labor force. Therefore, in order to solve the above-mentioned problems, a planting machine for automatically planting sugar cane seedlings is used.

[0003]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention Since fertilizers and chemicals are sprayed manually to seeds and seedlings planted using a planting machine, it is extremely troublesome and hard labor is required.
It was difficult to secure manpower.

Further, since the area is large, it takes many days, and the uneven amount of spraying causes inconvenience in growing.

In particular, the fertilizer and the chemicals used cannot be applied simultaneously. Therefore, the present invention is designed to spray fertilizers and chemicals at the time of planting seedlings.

[0006]

In order to solve the above-mentioned problems, the present invention mounts a tank on a traveling vehicle body in a plant for planting sugar cane seedlings, and has an upper end at an outlet at the bottom of the tank. The lower end of the spray pipe connected in communication is located directly above the seedbed, and a screw for transferring the stored fertilizer and chemicals to the outlet is provided in the bottom of the tank, and this screw is driven as the traveling vehicle travels. Therefore, the fertilizer spraying device in the plant for planting sugar cane seedlings, characterized in that they are interlocked by appropriate means, is adopted.

[0007]

With the above construction, the seedlings are automatically planted in the nursery while the planting machine is running, and the fertilizers and chemicals in the tank are sprayed from the spray pipe.

Further, since the screw is driven as the traveling vehicle travels, the fertilizer and the chemicals in the tank are sent to the outflow port, and the fertilizer and the chemicals are continuously sprayed from the spray pipe.

[0009]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, a belt conveyor 3 is mounted on the vehicle body 1 towed by a tractor or on a self-propelled traveling vehicle 1 and inclines between at least the middle of the carrier side and the head pulley 2.

In operation of the belt conveyor 3, the tail pulley 6 is driven by utilizing the rotation of the wheels 4 of the traveling vehicle body 1 through a transmission mechanism 5 composed of a sprocket and a chain.

On both sides of the surface of the belt conveyor 3,
There are two endless chains 7 that run with the belt conveyor 3.

The chain 7 travels over a sprocket 9 provided coaxially with the head pulley 2 and the tail pulley 6.

Further, both chains 7 are provided with bar members 10 each having an end attached thereto, and a space is provided at the front and rear of the chain 7 in which a plurality of parallel seedlings A are fitted.

Further, the hopper 11 is mounted on the traveling vehicle body, and the seedling A housed in the hopper 11 is dropped by the feeding device 12 and fed between the running bar materials 10 at the ascending slope.

The above-mentioned supply device 12 has two left and right endless chains 13 in which parts other than the head part are fitted in the hopper 11 (the chains 13 are interlocked so that the belt conveyor 3 is operated simultaneously with the operation thereof. ) And this chain 1
3 and the comb teeth 14 arranged side by side at a predetermined interval in front and back, and inside the hopper 11 (fill lime water to promote germination and suspend buds to minimize damage to buds)
The seedling A is scraped up by the comb teeth 14 and dropped on the chute 15, and the seedling A sliding on the chute 15 is the bar material 10
To fall on.

Further, the seedling A on the bar material 10 which is inverted by the head pulley 2 and runs downward is prevented from falling by the obstacle member 16 such as a plate material until just before the bar material 10 is inverted by the tail pulley 6. .

Further, the seedling A that has passed through the obstacle member 16 and has fallen after it has been dropped is slid onto the chute 17 from one end side, and is slid onto the seedbed while changing its direction by 90 degrees. ing.

When the planting machine as described above is used, the seedling A in the hopper 11 is fed from the feeding device 12 onto the chute 15, and the seedling gliding on the chute 15 is the bar material 10.
It fits on and is transported.

The transferred seedling A faces the chute 17 from above the bar material 10 and drops (plants) on the seedbed.

A tank 21 is mounted on the traveling vehicle body 1.

The above tank 21 has two tanks on the left and right in the illustrated case.
Individually arranged, the fertilizer is stored in one side and the medicine is stored in the other side, but the number is not always limited.

Furthermore, an extraction port 22 is provided at the bottom of the tank 21, and a fertilizer and a chemical are forcibly supplied to the outflow port 22 by a screw 23 provided at the bottom of the tank 21. There is.

The screw 23 is driven by the rotation of the wheels 4 and the pulleys of the belt conveyor 3 as the drive source as the traveling vehicle body 1 travels. Then, at the same time as planting the seedling A, fertilizer and chemicals are sprayed.

Further, the lower end of the spray pipe 24 having the upper end connected to the outflow port 22 is directed toward the nursery bed.

With the above construction, the seedling A is planted in the nursery with a planting machine, and the fertilizer and the chemicals in the tank 21 are forcibly sent to the outflow port 22 by the screw 23.
Spray from the outlet 22 through the spray pipe 24.

The spraying is not limited to before the seedling A is planted (illustrated) on the nursery bed, but may be sprayed after the planting and before covering with soil.

In the figure, 31 is a plow forming a nursery, 32 is a rotary blade for forming a ridge, and 33 is a plow for covering soil.

[0029]

Since the fertilizer (chemical) spraying device according to the present invention is configured as before, the fertilizer (the chemical together with the fertilizer) can be sprayed when the seedlings of sugar cane are planted.

Therefore, it is not necessary to spray fertilizer (which may also be used in combination with a chemical) after planting seedlings, and it is possible to significantly reduce the cost.
