  The asphalt composite storage silo according to the present invention has a container body with a charging gate at the top, a discharge gate at the bottom, and a heat insulation structure, and the upper part of the container body stands on the gantry. The support body is supported by a support that can be laid sideways, and the support body is erected so that the container body can be placed in an upright posture so that the asphalt mixture can be dispensed to the vehicle. It is configured to accept asphalt mixture directly from the vehicle as a sideways posture on the top surface. This storage silo has a small storage capacity of about 20 tons, for example, and the silo height is less than about 8 m.

  Standing and sideways means for supporting the container body are performed by an appropriate combination of a hydraulic cylinder and a link mechanism. For example, the tip of the piston rod of the hydraulic cylinder is pivotally attached to the upper end of the support, while the lower end of the hydraulic cylinder is pivotally attached to the first link member that is pivotally attached to the gantry. A link mechanism is employed in which one end of the second link member is pivotally attached to the tip, while the other end of the second link member is pivotally attached to the upper end of the support. In this link mechanism, when the piston rod of the hydraulic cylinder is extended to elevate the support body, the second link material pivotally attached to the support body is pulled, and this second link material becomes the first link material. By causing the link material, the hydraulic cylinder pivotally attached to the first link material rises, and the container body can stand up even with a short stroke hydraulic cylinder.

  In addition, sliding rollers are provided on the left and right lower portions of the container body, and guide rails are provided for guiding the container body to stand upright and lie down by sliding the sliding roller. In addition, a support material that supports the sliding roller on the lower side of the container body from below when the container body stands up is disposed so as to freely advance and retract.

  When the asphalt mixture is put into the container body, if the support body is laid down by reducing the piston rod of the hydraulic cylinder, the sliding roller on the lower side of the container body follows the guide rail. The link mechanism is folded while sliding and the container main body is placed sideways on the ground surface. When the container body is in a sideways position, the charging gate is opened, and the asphalt mixture loaded on the vehicle is directly charged into the container body through the opened charging port.

  When the asphalt mixture is completely charged, after closing the closing gate and extending the piston rod of the hydraulic cylinder, the link mechanism rises while the sliding roller on the lower side of the container body is guided by the guide rail. Is raised to place the container body in an upright posture, and the asphalt mixture thus charged is dropped into the bottom side of the container body and stored. When the asphalt mixture is shipped, the vehicle enters the lower part of the container body, then the discharge gate is opened, and a predetermined amount is weighed and paid out to the vehicle.

  As described above, the asphalt composite storage silo is a simple storage silo in which the container main body can be erected and laid down by a combination of a hydraulic cylinder and a link mechanism. It is possible to input directly from the vehicle by laying it sideways, reducing the cost of the apparatus by eliminating the input device, and easily installing and moving as a simple storage silo.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  In the figure, reference numeral 1 denotes a storage silo for storing asphalt mixture, and the container body 2 for storing the asphalt mixture has, for example, a storage capacity of about 20 t and a compact size with a height of less than about 8 m. In order to prevent as much as possible the hardening and deterioration of the asphalt mixture, which is a stored product, due to the temperature drop, the peripheral wall has a heat insulation structure, and the lower part of the container body 2 is tapered downward. While the conical shape has a drain gate 3 at its lower end that can be freely opened and closed, the ceiling of the container body 2 has a shape that is partially cut away, and the cut-out portion is filled with asphalt mixture. The input gate 4 is attached by a cylinder (not shown) so as to be freely opened and closed.

  The container body 2 is installed on a gantry 5 having a substantially gate shape, and the gantry 5 has a width that allows a vehicle for carrying in and out asphalt mixture to enter. Each of the lower ends of the pair of support columns 6a of the support 6 that supports the upper portion of the container body 2 is rotatably mounted on the mount 5 by the shaft body 7, while the upper ends of the pair of support columns 6a. The transverse member 6b and the container main body 2 spanned between the parts are pivotally attached to the shaft body 8 at two places so as to be rotatable.

  In order to make the support body 6 stand up and lie down, the tip end portion of the piston rod 10 of the hydraulic cylinder 9 is pivotally attached to the both ends of the cross member 6 b at the upper end of the support body 6 by the shaft body 11. The lower end portion of the hydraulic cylinder 9 is pivotally attached to the vicinity of the intermediate portion of the first link member 12 having a substantially triangular shape by the shaft body 13 and the lower end portion of the first link member 12 is mounted on the mount 5. The shaft 14 is pivotally attached to the shaft 14. In addition, one end of the second link member 15 is pivotally attached to the distal end portion of the first link member 12 by the shaft body 16, while the other end portion of the second link member 15 is supported by the support member 6. This is a link mechanism that is pivotally attached to the cross member 6b at the upper end of the shaft by a shaft 17 so as to be freely rotatable.

  The reason why the link mechanism using the first link member 12 and the second link member 15 is adopted is that the cylinder stroke is short for raising the container body 2 only by the hydraulic cylinder 9. When the piston rod 10 is extended to erect the support body 6, the second link material 15 pivotally attached to the support body 6 is pulled, and the second link material 15 becomes the first link material 12. As a result, the hydraulic cylinder 9 rises, and the container body 2 can stand up even with the hydraulic cylinder 9 having a short stroke.

  A pair of sliding rollers 18 are attached to the lower left and right sides of the container body 2, and a pair of guide rails 19 for guiding the sliding rollers 18 when the container body 2 is laid down and standing are arranged on the mount 5. Has been established. When the piston rod 10 of the hydraulic cylinder 9 is contracted, the first link member 12 and the second link member 15 are folded at the same time as shown in FIG. As a result, the container body 2 is smoothly turned over. Further, a support member 20 for supporting the sliding roller 18 from below when the container body 2 stands is attached by a cylinder 21 so as to freely advance and retract. Reference numeral 22 denotes a support base that supports the support body 6 when it is horizontally laid down.

  Next, a procedure for charging and discharging the asphalt mixture into the container body 2 of the storage silo 1 will be described. First, when the asphalt mixture is put into the container body 2, as shown in FIG. 6, the piston rod 10 of the hydraulic cylinder 9 is reduced and the first link member 12 and the second link member 15 are folded while supporting the support body. 6 is tilted, the container body 2 gradually lies sideways while the sliding roller 18 of the container body 2 is guided by the guide rail 19. When the container body 2 descends to the ground surface, the container body 2 rotates approximately 90 degrees to the side. It will be in the state of a fall posture.

  Subsequently, after the charging gate 4 of the container body 2 is opened, the asphalt mixture mounted on the vehicle A is directly charged into the container body 2. When a predetermined amount of asphalt mixture is introduced, the piston rod 10 of the hydraulic cylinder 9 is slightly extended to raise the container body 2 slightly and drop the asphalt mixture to the bottom side of the container body 2. Thereafter, the piston rod 10 of the hydraulic cylinder 9 is reduced again to place the container body 2 in a sideways posture, and the asphalt mixture is again introduced from the vehicle A. This operation is repeated several times and all of the asphalt mixture mounted on the vehicle A is put into the container body 2.

  When the charging of the asphalt mixture is completed, as shown in FIG. 7, the sliding gate of the container body 2 is raised by closing the charging gate 4 and then extending the piston rod 10 of the hydraulic cylinder 9 to raise the support 6. The container body 2 is raised while keeping 18 along the guide rail 19, and the container body 2 is raised while the hydraulic cylinder 9 is raised by raising the first link material 12 by raising the second link material 15. To do. When shipping the asphalt mixture, the vehicle A is entered and placed below the container body 2, the discharge gate 3 is opened, and the dispensing amount is measured by a measuring mechanism (not shown). A fixed amount of asphalt mixture is delivered to vehicle A and shipped.

  As described above, the storage silo 1 has a simple and compact structure in which the container body 2 can be raised and laid down by using the link mechanism of the hydraulic cylinder 9 and the link members 12 and 15, and the asphalt to the container body 2 is made. Since the vertical transfer device, which is a compound material input device, is not required, the device cost is low, and installation and transfer can be easily performed. In addition, if the silo height is less than 8m, the application for permission of the work is not required and the structure is compact, so it can be installed or moved anywhere in the city to become a sales base for asphalt composites. Will be convenient.

  In addition, the combination of the cylinder 9 and the link mechanism for raising and lowering the container body 2 is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention. Of course.
