[0009] The loading device of this invention is a loading device for loading stored materials into multiple storage tanks arranged on the same circumference in a plan view, and has a rotating shaft located at the center of a group of multiple storage tanks, and a loading chute and lid supported by the rotating shaft that can move horizontally around the storage tanks.

[0010] An embodiment of the dosing device of the present invention will be described in detail below with reference to the drawings. Figure 1 is a schematic side cross-sectional view of one embodiment of the dosing device of the present invention, Figure 2 is a schematic plan cross-sectional view, and Figure 3 is a schematic side view showing the dosing device of the present invention installed in a group of storage tanks.

[0011] As shown in FIGS. 2 and 3, the charging device 1 according to this embodiment is a charging device disposed above a plurality of storage tanks 6 having a charging port 61 at the upper part. The storage tanks 6 are arranged in a group of 9 on the same circumference in a plan view at the same angle (40°) to form a storage tank group 60. A charging port 61 is provided at the upper part of each storage tank 6, and a discharge port 62 for taking out is provided at the lower part. Further, a support frame body 4 made of steel is provided above the storage tank group 60, the charging device 1 is installed above the support frame body 4, and the charging port 61 of each storage tank 6 and the charging device 1 are connected by a tubular introduction pipe 5.

[0012] The stored material stored in the storage tank 6 is not particularly limited as long as it can be introduced into a normal storage tank. For example, each main raw material of compound feed and fertilizer, cement, resin material, short fiber material, wood chip, etc. can be exemplified.

[0013] In the charging device 1, a rotating shaft 11 is erected at a position corresponding to the center of the storage tank group 60, and the rotating shaft 11 rotates by the operation of a driving part 12 having a motor provided at the lower end part of the rotating shaft 11. Further, a charging chute 2 is connected to the rotating shaft 11, and a lid 3 is connected via an arm 31. The charging chute 2 and the lid 3 move in a circular motion in the horizontal direction by the rotation of the rotating shaft 11.

[0014] The charging chute 2 connected to the rotating shaft 11 is formed in a bent shape as shown in FIG. 1, the upper part is formed in a circular tube shape that coincides with the rotation axis of the rotating shaft 11, and has an upper end charging port 21 for charging the stored material at the upper end and a lower end discharge port 22 at the lower end.

[0015] The positional relationship between the lower end discharge port 22 of the charging chute 2 and the lid 3 is arranged on the same circumference and at the same angle in a plan view so as to correspond to the position corresponding to the charging port 61 of each storage tank 6, that is, the position of the upper end part of the introduction pipe 5.

[0016] Furthermore, in the feeding device 1 of this embodiment, a base portion 13 having a through hole 131 at a position corresponding to the lower end discharge outlet 22 of the feeding chute 2 and the arrangement position of the lid 3 is provided below the feeding chute 2 and the lid 3, and the base portion 13 is fixed to the upper part of the support frame 4. Furthermore, the through hole 131 provided in the base portion 13 is connected to the opening at the upper end of the introduction pipe 5, and the opening at the lower end of the introduction pipe 5 is connected to the feeding port 61 of the storage tank 6.

[0017] The feeding device 1 is also provided with a cylindrical housing 14 that covers the rotating shaft 11, the feeding chute 2, and the lid 3, and the lower end of the housing 14 is joined to the edge of the base part 13 to form an enclosed space. The upper center of the housing 14 exposes the upper end feeding port 21 of the feeding chute 2 and is formed in a bearing shape to support the rotation of the upper end feeding port 21 of the feeding chute 2. This allows the rotating shaft 11, the feeding chute 2, and the lid 3 to rotate within the housing 14, and makes it possible to feed the storage items through the upper end feeding port 21 of the feeding chute 2 exposed in the upper center of the housing 14.

[0018] Furthermore, a maintenance door 141 is provided on the side of the housing 14, and through the maintenance door 141, the operating status of the input chute 2 and the lid 3 can be checked and periodic cleaning and maintenance can be performed.

[0019] In addition, it is desirable that the feeding device 1 of the present invention be provided with a control unit that controls the positions of the lower discharge outlet 22 of the feeding chute 2 and the lid 3 so that they always accurately coincide with the positions corresponding to the feeding inlet 61 of the storage tank 6. Specifically, for example, as shown in Figures 1 and 2, a contact sensor 15 is provided at a position on the inner wall of the housing 14 that corresponds to the position of the feeding inlet 61 of the storage tank 6, and a contact member 23 is provided on the feeding chute 2, and control is made to stop rotation when the contact member 23 comes into contact with the contact sensor 15, so that the positions of the feeding chute 2 and the lid 3 stop at the exact positions of the feeding inlet 61 of the storage tank 6.

[0020] As another control method, the rotational operation of the rotary shaft 11 may be controlled such that the positions of the charging chute 2 and the lid 3 always stop at the position of the charging port 61 of the storage tank 6 by controlling the rotation angle of the motor of the drive unit 12.

[0021] The operation of the charging device of the present invention will be described below. First, the motor of the drive unit 12 is operated to rotate the rotary shaft 11, and the lower end discharge port 22 of the charging chute 2 is rotationally moved to the upper opening position of the introduction pipe 5 to which the charging port 61 of the storage tank 6 for charging the stored material is connected. At this time, the lower end discharge port 22 of the charging chute 2 accurately stops at a predetermined position by a control unit including a contact sensor 15 provided on the inner wall of the housing 14 and a contact member 23 provided on the charging chute 2. Further, by rotationally moving the lower end discharge port 22 of the charging chute 2 to a predetermined position, the charging port 61 of another storage tank 6 that does not charge the stored material is covered via the introduction pipe 5 by the lid 3.

[0022] Next, the stored material is introduced from the upper end charging port 21 of the charging chute 2 using a stored material introduction device (not shown) or the like. The introduced stored material is discharged from the lower end discharge port 22 through the charging chute 2 and then introduced into the storage tank 6 through the introduction pipe 5. At this time, since the other storage tanks 6 that do not charge the stored material are indirectly covered, it is possible to prevent the stored material, dust, dirt, etc. being introduced from entering.

[0023] Also, when introducing the stored material into another storage tank 6 thereafter, the charging chute 2 is rotationally moved to the storage tank 6 to be introduced, and the stored material is introduced into the predetermined storage tank 6 through the charging chute 2 and the introduction pipe 5. By repeating these operations, the stored material can be easily and accurately introduced into a predetermined storage tank 6, and for the other storage tanks 6, it is possible to perform highly reliable storage without mixing of stored materials other than the storage purpose, dust, dirt, etc.

[0024] As described above, the charging device of the present invention has been described based on the embodiments, but the present invention is not limited to the above embodiments, and various modifications can be made without departing from the gist thereof.

[0025] For example, in the charging device 1 of the above embodiment, one charging chute 2 and eight lids 3 are provided for nine storage tanks 6. However, for example, one charging chute 2 and one lid 3 may be provided for two storage tanks 6, or one charging chute 2 and five lids 3 may be provided for six storage tanks 6. The number of the charging chute 2 and the lid 3 can be appropriately determined according to the number of the storage tanks 6.

[0026] In addition, in the charging device 1 of the above embodiment, nine individually independent storage tanks 6 are exemplified. However, in the integrally formed storage tank, the storage part may be completely divided internally and have an independent structure. For example, it is applicable to a storage tank having a donut-shaped integrated structure in plan view and an internally evenly divided structure.

[0027] According to the charging device having the above configuration, when charging the storage material into a specific one of the storage tanks in the storage tank group, the inlets of the other storage tanks are covered with lids, so it is possible to reliably prevent the storage material from entering the storage tanks other than the storage tank being charged and the entry of dust and dirt.
