Description

[Detailed Description of the Invention] This invention relates to a manufacturing method for manufacturing soil for raising seedlings,
The granulation process is different depending on the clay content of the frozen soil, but the granulation process can be changed depending on the granulation state or the necessity of granulation of the soil to obtain the desired culture. and
Another invention is to separate fine granular soil after granulation into granular soil and fine soil, and then mix them again in a certain ratio to obtain stable seedling cultivation soil. Therefore, the first invention takes the following technical measures. That is, a frozen soil drying device (3) that dries frozen soil (1) while supplying and transferring it into a rotating cylinder (2), a crusher M (4) that crushes the soil on the dried soil, and a soil clod from this crushed soil. A granulating device (6) that granulates the fine soil obtained through a sorting device (5) that separates and removes the fine soil, and a weighing and packaging device (7) that weighs and packages the granulated granular soil.
(a), and the thin soil is directly weighed and packaged by a device (7).
The method for manufacturing soil for raising seedlings is configured such that the supply can be freely switched between the step (b) of supplying the seedling soil.

With this configuration, the present invention has the following technical effects. That is, when frozen soil (2) containing clay that exists under natural conditions is supplied into a rotating cylinder (1) and transferred while being dried by heating etc., the presence of clay in the frozen soil causes As the granulation process takes place during drying, and mechanical pressure during rotation is applied between the grains, a dry layer that is relatively hard to crumble is produced, and this dried layer is crushed.
The fine soil is crushed by the second device (4) and separated into fine soil and soil clods by the sorting device (5). Depending on the degree of granulation, etc., when the fine soil is taken out directly as a product, it is directly weighed and packaged. (7) Switch the transfer supply direction to the supply process (b),
In addition, in cases such as when fine granulation is incomplete, a.
By switching to the step (a) that goes through the granulator (6) and adding granulation, it is possible to obtain highly granulated soil. In the case of soil that increases particle size, by going through this step (a),
It can be processed as a product using a weighing and packaging device (7),
Same drying device (3), crushing device (4), sorting device (5)
, a measuring and packaging device (7), etc., to efficiently produce the desired soil.

Next, the second invention takes the following technical measures. That is, a granulating device (6) that granulates fine soil, a drying device (8) that dries this granulated granular soil, a rough sorting device (9) that separates and removes the top of the lumps from this dry granular soil, A coarse sorting device QO1 separates the granular soil obtained by the coarse sorting device (9) into granular soil and fine soil, and a mixing device QO1 mixes the granular soil and fine soil in a predetermined ratio. This is a method of manufacturing soil for raising seedlings, which is characterized in that the soil is produced through the process.

With this configuration, the present invention has the following technical effects. That is, fine soil is supplied to a granulator (6) to be granulated, and this is further dried in a dryer (8), and the top of the lumps is separated and removed by a rough sorter (9).

and dried. This dried soft soil is supplied from the conveyor (A) to the coarse sorting device (9), where the upper lumps are supplied to the crusher G by the conveyor OQ and crushed, and then again to the coarse sorting device (9). 9) and processed.

The leaking granular soil is once supplied to the tank (c) via a conveyor (to), a bucket elevator, etc.
7) etc., the soil is supplied to a rough sorting device (10), where it is sorted into relatively large-diameter granular soil and small-diameter fine soil, and the granular soil is supplied by a conveyor onto a conveyor, The fine soil is supplied by the conveyor (goods) through 0 hoppers onto the conveyor (goods) and mixed at a constant mixing ratio.At this time, the amount of granular soil supplied from the hopper (6) is The supply amount of fine soil can be adjusted and controlled. The soil mixed with granular soil and fine soil in this way is packaged in the measuring and packaging device (7). Also, the overflow in the hopper (6) The fine soil is reduced to the bucket elevator 0υ by the conveyor Q and is granulated again.

Moreover, when supplying heat moss, if it is supplied from the tank (6) to the transfer tube (1) through the transfer tube (6),
Fine soil and peat moss are mixed in a transfer tube (7) under water and granulated in a granulator (6). At this time, peat moss has good miscibility and adsorption properties with fine soil and fertilizer, and the granular soil dried in a drying device (8 tons) crumbles and melts, making it difficult to separate the fertilizer. The granulated material mixed with these materials does not easily crumble even when subjected to the action of the subsequent rough sorting device (9), coarse sorting device 00, etc., and produces and maintains high-quality culture soil.
