Therefore, the rotary shaft 120 is screwed into the communication hole 131 of the elevating plate 130. Accordingly, according to the direction in which the rotary shaft 120 is rotated, the elevating plate 130 is capable of raising and lowering along the axial direction of the rotary shaft 120.

At this time, since the body 20 is supplied with the solids to the open upper side, the elevating plate 130 provided inside the body 20 is preferably made of a minimum size to ensure the supply amount of the solids. For convenience, the elevating plate 130 is shown in a bar (har) type.

In addition, the rotary shaft 120 is preferably provided with a nut member 133 that serves as a stopper to prevent the lower departure of the elevating plate (130).

In addition, the elevating shaft 140 is connected to the elevating plate 130 to be raised and lowered together with the elevating plate (130). And, the lifting shaft 140 is provided with a door plate 30 on the lower side. The door plate 30 opens and closes the opened lower side of the body 20. That is, as the door plate 30 rises toward the inner center direction of the body 20, the lower side of the body 20 having a light beam narrowing shape is opened. On the contrary, when the door plate 30 is provided inside the body 20 to contact the lower inner surface of the body 20, the lower side of the body 20 is blocked.

Accordingly, the lifting shaft 140 is preferably located at the central axis of the body 20.

At this time, the door plate 30 is made of the same disk or polygonal plate shape as the lower inner side of the planar body 20.

In addition, the door plate 30 is preferably provided with a packing member 190 on the circumferential surface to improve the sealing force. At this time, the packing member 190 is applicable to a variety of materials, such as rubber.

Accordingly, the elevating shaft 140 is raised and lowered together with the elevating plate 130 to open and close the lower side of the body 20, the stirring blade 150 is rotated when the elevating shaft 140 is rotated body 20 The solid inside is stirred. The stirring blade 150 may be made of hard or soft.

In particular, in order to improve the stirring force, the lifting shaft 140 is preferably rotated in both directions repeatedly. Thus, the rotationally operated motor 160 is preferably a step motor.

As in Figure 5, the stirring blade 150 is preferably provided detachably on the lifting shaft 140. This is to reduce maintenance costs by replacing only the stirring blades 150 when each of the stirring blades 150 is broken or deformed.

For example, the stirring blade 150 has a flange 152 to increase the contact area and the peripheral surface of the elevating shaft 140. In the state where the flange 152 and the lifting shaft 140 are in surface contact, the binding member 154 binds the flange 152 and the lifting shaft 140. Here, the binding member 154 is a mechanical fastening element such as a bolt. Accordingly, the stirring blades 150 are each detachably coupled from the lifting shaft 140.

In addition, the rotary movable motor 160 is preferably protected from the solids supplied into the body 20. Thus, the rotatable motor 160 is protected by the cover 162. Cover 162 is preferably installed detachably fixed to the elevating plate (130).

Since the guide shaft 172 fixed to the upper side 22 is inserted into the insertion hole 174 of the elevating plate 130, the elevating plate 130 is prevented from rotating by the guide shaft 172. And, the elevating plate 130 is raised and lowered along the rotation shaft 120 on the one side relative to the center, and the other side is raised and lowered along the guide shaft 172 to be able to raise and lower stably.

Of course, the guide shaft 172 is deformable in various shapes, it is fixed to the body 20 in various ways.

In addition, the elevating shaft 140 is preferably provided with a spiral spiral plate 180 in a portion adjacent to the door plate 30 in order to improve the sealing force with the lower inner surface of the body 20.

That is, the spiral plate 180 is formed to contact the lower inner surface of the body 20 continuously along the spiral trajectory on the lower side of the elevating shaft 140.

Thus, the solids are optionally prevented from being discharged from the lower side of the body 20 by the spiral plate 180 and the door plate 30.

The body 20 is supported by the support 40 installed on the bottom and spaced apart from the bottom by a predetermined distance.

As shown in FIG. 6, first, the operator drives the elevating driving motor 110 to rotate the rotary shaft 120 in one direction, so that the elevating plate 130 is lowered to the set height.

Thus, as the lifting shaft 140 descends together with the lifting plate 130, the spiral plate 180 and the door plate 30 block the open lower side of the body 20.

Thereafter, the solids are supplied to the upper side of the body 20.

When the solids are completely supplied or the discharge of the solids is requested, the operator drives the elevating motor 110 to rotate the rotary shaft 120 in the other direction. Then, the elevating plate 130 and the elevating shaft 140 is gradually raised by a set distance.

At this time, the door plate 30 is fully raised into the interior of the body 20, the solid material can be continuously discharged by the capacity corresponding to the lower cross-sectional area of the body 20.

Of course, the lifting shaft 140 is rotated during the operation of the rotary motor 160, it is possible to stir the solid by the stirring blade 150.

The reference numerals not described are replaced with those described above.

After the set time has elapsed, or by the operator, the rotary shaft 120 is rotated in one direction so that the open lower side of the body 20 is tightly sealed by the door plate 30 and the spiral plate 180.

Meanwhile, as shown in FIG. 7, the solid storage hopper 10 according to another embodiment of the present invention includes a body 20, a door plate 30, and a lift opening / closing unit 100.
