  The horticulture soil sieve platform described above is configured to simultaneously screen a sieve support holding a plurality of soil sieves while swinging up and down, reciprocating or rotating around a support shaft. Since the reciprocation or rotation is performed while supporting the sieve support with only one support shaft, it is very difficult to maintain the horizontal state, and as a result, the reciprocation or rotation is performed while swinging up and down. Will be moved. The act of swinging the sieve support up and down in this way has a significant disadvantage that workability is extremely poor because the user's physical wear is large, and the screen is held with one hand and the screen with the other hand. The working method of swinging the support also has a problem that it is difficult for women, children, and elderly people to use.

  Therefore, the present invention can obtain a plurality of types of soils having different particle sizes at a time by holding a plurality of soil sieves and reciprocating or rotating horizontally, and also improves the workability. In addition, an object of the present invention is to provide a soil sieving tool for horticulture that can be easily and easily screened with only one hand by making the work stand a stable shape.

  In order to achieve the above object, according to the present invention, a holder for superposing and storing a plurality of soil sieves having different mesh sizes is detachably mounted on a stand provided separately. A garden sieving device which is formed so that the holder can be reciprocated horizontally, and the holder is formed in a lattice shape, a cross shape, a two-letter shape, a three-letter shape, etc. A ring-shaped main body having a bottom, a plurality of holding members erected to hold a plurality of earth sieves, and a handle provided at the front of the main body The stand is formed in a substantially iron bar shape with its legs widened in a letter C shape and the opposite upper ends of the legs connected to each other by a horizontal axis. Using a pedestal frame and a straight connecting frame) A pedestal which is formed in a substantially rectangular cone shape, in which a structure formed by at least two guide frames attached to the top inside of the pedestal.

  The present invention according to claim 2 is configured such that the above-described guide frame is formed in an inverted U shape having an open top.

  According to a third aspect of the present invention, a soil sieve receiving portion is formed by bending the lower portion of the holding member inward without providing a grid-like bottom in the main body of the holder.

  According to a fourth aspect of the present invention, there is provided a structure in which a drop-off preventing frame for a holder that reciprocates horizontally is provided on the upper portion of the pedestal.

  The horticultural soil sieve according to the present invention superimposes a desired number of soil sieves having different mesh sizes, and horizontally reciprocates or rotates the plurality of soil sieves, for example, to superpose three soil sieves. In such a case, four types of soils with different particle sizes can be obtained, so the number of soil sieves plus one type of soil can be screened in one operation, and this significantly reduces the time required for the operation. It has a great effect of being able to work, and since it has a structure that can be easily and easily operated with only one hand, it has an unprecedented remarkable effect that it can work efficiently and with little labor is there. Furthermore, since the holder according to the first embodiment of the present invention has a grid-like bottom, there is an advantage that even a slightly smaller one can be used as long as it can be accommodated in the holder. The pedestal is formed into a stable square base using a pedestal frame and a connecting frame with an expanded lower part, so that the stand does not fall down during sieving work, and it is safe and It has the feature that it can work quickly.
