BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a table for agricultural work such as fruit picking and picking.

[0002]

2. Description of the Related Art Fruits such as pears are continuously managed in an upward direction, and there is much fatigue such as stiff shoulders. In particular, the fruit picking and picking work is a precise work and causes great physical fatigue. Conventionally, in order to adjust the height of the scaffold, a plastic container for beer and juice has been used as a platform. However, since the container was too expensive, it was difficult to go up and down. In addition, since the container is heavy, it is inconvenient for complicated movement. Further, the small area resulted in an unstable work posture, which caused physical fatigue.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned drawbacks of the prior art, to be lightweight, easy to carry, easy to ascend and descend, stable and easy to work.
An object of the present invention is to provide a farm work table that is useful for reducing the burden of upward work.

[0004]

The agricultural work table according to the present invention is roughly divided into the following two. First, the first agricultural work table is made of a plastic foam, and the upper surface and the lower surface are substantially parallel. Further, the second farm work table is made of a plastic foam, and has a lower surface formed obliquely. In the two farm work tables, the upper surface is formed in a step shape, so that the up and down can be easily performed. In the present invention, the cord can be easily moved by providing a string insertion hole at an arbitrary position on the agricultural work table and pulling the string by hand through the string. A plastic sheet or a rubber sheet can be laminated on the upper surface of the present invention to reinforce the strength of the foam. As the plastic sheet, vinyl chloride, polyethylene or the like can be applied, and as the rubber sheet, a sheet of natural rubber or synthetic rubber can be applied. As a method of laminating, a method using heat fusion, an adhesive or a pressure-sensitive adhesive can be applied. As the plastic foam of the present invention, various foams such as polystyrene foam and vinyl chloride foam can be applied.
Polyolefin foams are preferred in terms of hardness, elasticity and the like. The base material of the polyolefin foam is an ethylene-vinyl acetate copolymer, an ethylene-propylene copolymer, an ethylene-propylene-diene copolymer, or a content of ethylene and each acrylate of methyl, ethyl, propyl, and butyl of 45%. Or at least one of these copolymers, or a commercially available high-
Medium and low density polyethylenes, chlorinated polyethylenes and polypropylenes are preferred, and polyethylene or ethylene-vinyl acetate copolymer is preferred from the viewpoint of hardness and workability. The expansion ratio of the polyolefin foam is preferably 20 to 50 times. If the expansion ratio is less than 20 times, the weight is large and the movement is inconvenient. On the other hand, if the expansion ratio exceeds 50 times, the hardness becomes insufficient, and the foam tends to contract when the work is repeated. If the hardness is insufficient, the feet tend to get tired during work.

As a method for producing the polyolefin foam of the present invention, various conventionally known foaming methods can be applied, but a method for producing a thick foam by a two-stage foaming method is preferable. The two-stage foaming method suitable for the application of the present invention will be described in detail.
If necessary, a foaming aid, a filler, and a pigment are added and kneaded, and the resulting crosslinkable and foamable composition is heated in a mold under pressure to partially decompose the foaming agent and the crosslinking agent. ,
Next, the resulting intermediate foam is heated and foamed under normal pressure.
The heating conditions of such a two-stage foaming method may be the same as those in the prior art (JP-B-45-29381, JP-B-2-42649).
No. JP-B-3-67613), for example, 130 to
The heating conditions in the above preferred method may be set appropriately according to the method used in the range of 200 ° C., and the heating under pressure is performed in the range of 130 to 160 ° C. depending on the type of the foaming agent.
Normal pressure heating may be set in the range of 140 to 200 ° C.
The two-stage foaming method is a preferred method, and is not particularly limited to the two-stage foaming method, and a pressure one-stage foaming method, a normal pressure one-stage foaming method, or the like can be employed. In order to obtain the agricultural work table according to the present invention from the thick foam produced by these methods, it may be processed by a method such as cutting, or the mold may be approximately the same size as the agricultural work table, It may be formed in a hot pressing or foaming step. Alternatively, a method for manufacturing a molded article having a desired shape by heating a small piece obtained by cutting a polyolefin foam with hot air or the like, melting the surface thereof, and then overfilling the resultant in a compression molding die and compressing it ( JP-A-59-155019) can also be employed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
The present invention will be specifically described. 1 to 4 show a first farm work table according to the present invention, and FIGS. 5 and 6 show a second farm work table according to the present invention. FIG. 1 is a perspective view showing a rectangular parallelepiped agricultural work table. The material is polyethylene foam 1, and the expansion ratio is about 30 times. One side of the upper surface is about 100 cm and the height is about 15 cm, but the size is not particularly limited. The upper and lower surfaces are substantially parallel, and all surfaces are square or rectangular. A string insertion hole 2 is provided near the corner, and penetrates from the upper surface to the lower surface. FIG. 2 is a perspective view showing a farm work table having an upper surface formed in two steps. The material is the same as in FIG. The upper surface is formed at two levels. There is a cord insertion hole 2 near the corner. FIG.
Is a perspective view of an agricultural work table formed in a convex shape, and the material is shown in FIG.
Is the same as A string insertion hole 2 is provided near the corner. FIG. 4 is a diagram in which a polyethylene sheet 3 is laminated on the upper surface of the agricultural work table of FIG. 1 with an adhesive. Since the polyethylene sheet 3 has a high hardness, it reinforces the hardness of the polyethylene foam 1, eliminates the burden on the feet during work, and prevents the foam from shrinking due to partial load during work. FIG.
Has a slanted lower surface, and has a shape that allows work on the slope. The material is the same as that of FIG. 1, and a string insertion hole 2 is provided near the end. FIG. 6 is a perspective view of the agricultural work table of FIG. 5 in which the upper surface is formed in two steps, so that it is easy to go up and down. The upper surface of the agricultural work table according to the present invention may be flat, but in order to prevent the scaffold from slipping, corrugations, irregularities, etc. may be formed on the upper surface by a method such as graining. The shape of the agricultural work table according to the present invention is not limited to the above embodiment, and a trapezoid, a circle, an ellipse and the like can be applied.

[0007]

[Effect of the Invention] The farm work table according to the present invention is made of plastic.
Because it is a stick foam, it is lightweight and can be easily moved. In addition, the movement is further facilitated by passing the string through the through hole. Since the size of the agricultural work table according to the present invention can be freely selected, the upper surface serving as a scaffold can be widened, and there is a sense of stability at the time of work, and the upward work is not troublesome. If various types of farm work tables having different lengths, widths, and heights are prepared , the work efficiency can be improved by selecting a suitable one according to the type of farm work. In the present invention, when a farm work platform with a high scaffold is used, the upper surface is formed in a step-like manner, so that it is easy to go up and down. Also,
By forming the lower surface of the agricultural work table according to the present invention at an angle, it is possible to work on a slope. As described above, the agricultural work table according to the present invention is suitable as a table for farm work such as pruning and picking of fruits such as pears, and can reduce physical and mental fatigue.
