JPS60746Y2 - Soil covering device in seedling box - Google Patents

Description

[Detailed explanation of the invention] The seedlings attached to the rice transplanter are grown in a synthetic resin box called a seedling box.

The seedlings grown in the seedling box are loaded into the rice transplanter as soil material, so the bed soil, seed rice, and covering soil are all applied evenly.

If the seedlings are uneven, it will seriously affect the planting action of the rice transplanter and may even lead to missing plants.

Evenly filling the seedling box with bed soil is a relatively hassle-free task.

In other words, all you have to do is supply extra bed soil and level out the excess.

If you level it with a board, you will have a completely horizontal and completely uniform bed of soil.

There is no other way to ensure uniform sowing of rice seeds than to improve the feeding mechanism, but a system that is currently in a nearly satisfactory state has been obtained.

However, there are various problems with soil covering equipment.

Generally speaking, the thinner the amount of soil covering, the better.

In other words, it is best that the surface of the seed rice is only slightly exposed, and that sufficient soil is supplied around the seed rice.

Therefore, even if there is unevenness after covering the soil, it is impossible to level it out because it will move the seed rice.

Therefore, conventionally, various diffusion devices have been attached to the flow path of soil for covering soil.

For example, a rotating sieve or a swinging sieve.

However, all of them are not only expensive, but also do not have a sufficient effect.

Therefore, this devised idea can be expected to have a sufficient diffusion effect,
Moreover, it is designed to be carried out at the lowest possible cost.The seedling raising box is moved horizontally, and a seed feeding device and a soil covering device are installed above the horizontal transporting device of the seedling raising box to prevent the seedlings from being covered with soil after sowing. In this structure, the soil covering device is an endless belt type soil covering device in which an endless belt is wound around the bottom of the hopper, and a seedling raising box is provided in which piano wire is stretched in the flow path above the discharge of the endless belt. This is the structure of the soil covering device.

To explain with a diagram, FIG. 1 shows a conventional example. A is a cross-feeding device, B is a supply hopper, C is an endless belt, and D is a seedling box. When the guide roll E of the cross-feed device A rotates, the seedling box is The belt moves to the left, and by rotating the endless belt C, the covering soil is released.
This is what was being diffused on the oscillating sieve F.

The oscillating sieve F of this conventional example is expensive and ineffective, so it has been improved, and will be explained with reference to FIG. 2. Reference numeral 1 indicates a seedling growing box, and 2 indicates a cross-feeding device thereof.

The traversing device 2 is horizontally long and has a large number of guide rolls 3 arranged on a desired number of shafts at regular intervals.

A bed soil supply device, a seed rice supply device, a soil covering device 4, etc. are installed on the transverse transport device 2.

The soil covering device 4 includes a supply hopper 5 and an endless belt 6, and the endless belt 6 is wound around the bottom of the supply hopper 5.

A single piano wire 10 is placed horizontally below the discharge end 7 of the endless belt 6 and in the flow path 9 of the discharge top 8.

This point is a feature of the present invention.

Since the present invention has the above-described configuration, when the endless belt 6 rotates in the direction of the arrow A, the covering soil in the supply hopper 5 is fed out little by little, and the discharge top 8 is caused to flow down as shown in FIG.

At this time, in the present invention, since one piano wire 10 is placed in front of the flow path 9 of the upper discharge part 8, the upper part of the discharge part 8 is completely bisected in both the front and rear directions as shown in FIG. However, the dispersion width of the discharge top 8 can be widened as in the case of the conventional oscillating sieve F.

Conventionally, as a method for dispersing soil covering, a rotary sieve or a swinging sieve F was attached to the position where the piano wire 10 of the present invention was attached.

However, the above-mentioned oscillating sieve F is not a complicated and expensive scale with an eccentric rotating mechanism, and its ratio does not sufficiently diffuse.

In the present invention, a seedling raising box is transported horizontally, and a seed rice supplying device and a soil covering device are provided above the horizontal transporting device of the seedling raising box to cover the soil after seed rice is sown, and the soil covering device is installed in a hopper. The soil covering device is configured as an endless belt type soil covering device with an endless belt wound around the bottom, and a piano wire is stretched in the flow path above the discharge of the endless belt to disperse the covering soil. Because of this structure, not only can it be implemented at a much lower cost than conventional methods, but also a better dispersion effect can be expected.
