In addition, in Figure 2 is to be formed in the same manner as in Figure 1, but the four fixed to the fixed plate 13 to the lower end of the four pillars 12 is configured to be loaded on the upper surface of the stationary plate (13).

In addition, Figure 3 is connected to the configuration shown in Figure 2 (one variable plate 11, four pillars 12 and one fixed plate 13) in the transverse direction so as to increase the load space in the transverse direction An example is shown.

In addition, in the case of FIG. 4, four pillars 12 are assembled on one fixing plate 13 and two variable plates 11 are assembled on the four pillars 12 so that two storage spaces are provided in the longitudinal direction. An example to be formed is shown. In this case, it is natural that the number of loading spaces can be freely adjusted in the longitudinal direction by adjusting the number of the variable plates 11.

According to the available space as shown in Figures 1 to 4 the present invention is to be able to freely adjust the loading space in the transverse direction as well as the longitudinal direction.

In this invention, as shown in Figure 5 for the assembly as shown in the example of the assembly between the adjacent variable plate 11, the variable connecting piece 112 is in contact between the adjacent variable plate 11, the adjacent variable connecting piece It is to be connected to the bolt by the connection hole (112-1) opposite to (112).

In this case, the material of the washer 123 is preferably composed of an elastic material.

8 illustrates an example in which the moisture absorbing member 14 is placed in the crane hanger 115 as an embodiment of the present invention. That is, the moisture absorbing member 14 is placed in the opposite crane hanger 115 so that the moisture absorbing member 14 is detachably formed under the variable plate 11 in the lower loading space of the variable plate 11. Moisture is one of the important factors that cause equipment failure and corrosion in loaded agricultural machinery.In the case of agricultural machinery that are loaded after use, moisture is often stored in a state where moisture is not sufficiently removed. This causes the moisture absorbing member 14 to absorb such moisture to prevent equipment failure of loaded agricultural machinery and the like.

The moisture absorbing member 14 includes one or a mixture of ocher, silica, bottom ash, and activated carbon as a porous material, and it is reasonable to discolor by moisture absorption to include cobalt chloride or copper sulfate as an additive.

For example, a mixture containing 10 to 20 parts by weight of silica, 10 to 20 parts by weight of bottom ash, 1 to 5 parts of cobalt chloride or copper sulfate, is mixed and stirred with respect to 100 parts by weight of crushed ocher powder, and then pressed by a compression molding machine. It is to be made in the form of a block, and then to heat up the organic matter contained in the voids of the member by heat processing to maximize the amount of micropores. The moisture absorbing member 14 is pale yellow by the color of ocher when dried, and is changed into brown as moisture is absorbed, and is changed into reddish brown when saturated.

The moisture absorption member 14 is to increase the moisture absorption efficiency as the micro-pores are formed by the material and plasticity. In addition, by adding cobalt chloride or copper sulfate, the color of the moisture absorbing member 14 is discolored in accordance with the absorption of moisture, so that the saturated moisture absorbing member 14 is detached from the crane hanger 115, dried, and then remounted. .

Meanwhile, the moisture absorbing member 14 may be used as it is in the form of a block by including the porous material and the additive. However, as the amount of porous material is added for moisture absorption, the moisture absorbing member 14 may be easily crushed. As the strength decreases in the state, as shown in FIG. 8, the porous layer 143 and the porous layer 143 manufactured in the form of blocks by including the porous material and the additive are attached to the porous layer 143 to prevent crushing. Also, the reinforcing layer 142 made of a nonwoven fabric having hygroscopicity may be configured to be alternately formed.

More preferably, the moisture absorbing member 14 has a watertight casing 141 formed at both ends thereof in contact with the crane hanger 115 so that the crane hanger 115 is corroded by moisture absorption of the moisture absorbing member 14. To prevent it. Wherein the waterproof casing 141 should be made of a waterproof material, such as rubber.

Meanwhile, in the vertical and horizontal variable pallets 10 of the present invention, the variable plate 11, the pillar 12, and the fixed plate 13 are formed of iron material as shown in FIG. 5. It is preferable to use the material apply | coated by the antirust coating layer (c) for the base material f. This is mainly to allow the agricultural machinery is loaded in the loading space formed by the present invention, the fertilizer components, etc. are deposited in the used agricultural machinery, such fertilizer components, such as the variable plate (11) in contact with the configuration of the present invention causes acidification This corrosion will result in the deterioration of the structural durability of the present invention, there is a problem that can be transferred to the agricultural machinery loaded with corrosion once generated in the configuration of the present invention, such as variable plate (11) In the present invention, each material is used so that the material coated by the antirust coating layer (c) on the base material (f) of iron material is used.

When explaining the composition of the anti-corrosive coating layer (f) in more detail 2 to 10 parts by weight of triglycidyl isocyanate with respect to 100 parts by weight of polyester resin, 30 to 50 parts by weight of calcium carbonate and shell powder mixture, 20 to 30 parts by weight of titanium dioxide Part, 15 to 25 parts by weight of barium sulfate, 1 to 5 parts by weight of silicon carbide powder, 1 to 5 parts by weight of alumina powder to be formed by powder coating.

The triglycidyl isocyanate is 2 to 10 parts by weight based on 100 parts by weight of the polyester resin as a curing agent, when blended to less than 2 parts by weight, the flexibility is lowered, and if it exceeds 10 parts by weight, thus causing an appearance defect. It is limiting.

As the filler, the mixture of calcium carbonate and shell powder is used in the above limited range. If the content is less than 30 parts by weight, the expression of the function cannot be expected. . Here, the calcium carbonate used as the filler is to improve the dispersibility, and in particular, the shell powder is mixed with the calcium carbonate as the filler, and the reason is that the shell powder functions to prevent acidification. By mixing the powder, the antirust coating layer f is intended to improve resistance to acidification. That is, fertilizer components deposited on agricultural machinery and the like have a mechanism for causing acidification, and when such fertilizer components come into contact with the composition of the present invention, acidification is caused to cause corrosion. In the anti-corrosive coating layer (f) proposed in the present invention is a shell powder is formulated to prevent acidification by the fertilizer component and the like. As a result of the applicant's use, it is considered that mixing the calcium carbonate and the shell powder in a weight ratio of 50:50 is advantageous in terms of dispersibility and rust resistance.

The titanium dioxide is used as a white pigment, and the reason for limiting the mixing ratio as described above is to give color and hiding power to the coating film, to reinforce mechanical strength and durability, and to give fluidity to have an appropriate viscosity for the coating process.

The barium sulfate is used as a sieving pigment, and the reason for limiting the mixing ratio as described above is to increase the bulk density as a function of the filler to give smoothness, and to properly express the gloss loss effect in the finished state.

In addition to the antirust coating layer (f) of the present invention, the shell powder is blended with a filler in order to improve corrosion resistance, and silicon carbide powder is further blended. The silicon carbide has a function of preventing salt, and so on. Since the deposited fertilizer component has a problem that may cause salt damage, including chlorine, the silicon carbide is added to express the function of salt prevention. In addition, the reason for limiting the content of the silicon carbide as described above is to limit it as described above because it may cause brittle fracture of the coating layer when the content of silicon carbide exceeds the content.

In addition to the antirust coating layer (f) of the present invention, the alumina powder is further blended, and in the case of alumina powder, the shell powder assists the shell powder in corrosion resistance, and gives thermal insulation to increase the temperature of the adherend, that is, the substrate (f). To reduce the cracks caused by the difference in thermal expansion heat. The reason for limiting the content of the alumina powder as described above is to limit as described above because the flatness, the flexibility is reduced when the content exceeds.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
