Description

[Detailed Description of the Invention] The present invention relates to a vertical conveyance device for an asphalt mixture silo for temporarily storing asphalt mixture used as a paving material, and more particularly to a gate device for packets for conveying asphalt mixture.

In the vertical conveyance device of an asphalt mixture silo, the bucket that conveys the material has a long travel distance, so a gate device is installed at the bottom end of the packet.・If the discharge is controlled by a fluid pressure cylinder, there will be problems with the working fluid piping, etc. Conventionally, the material was released by tipping over the packet.

However, in view of the smooth discharge of material and the structure of the device, a lower discharge type packet is preferable, so in this invention, pneumatic,
This paper proposes a gate device that opens and closes without using a power source such as hydraulic pressure.

That is, the present invention utilizes the forward and reverse rotation of a winch to rope a packet for transporting asphalt mixture, which is equipped with a roller that rotates in sliding contact with the sliding surface of a guide rail installed from the ground surface to the material input section at the top of the silo main body. In a vertical conveyance device for an asphalt mixture silo that is raised and lowered by rolling in and letting out, a gate member rotatably supported by a pivot pin is disposed at the lower end of the packet, and the gate member is attached to an elastic body such as a coil spring. is compressed and is always urged in the closing direction with a predetermined pressure by an internal cylinder, and a rotatable gate roller is disposed on the gate member, and the gate roller is guided by the upper force of the material input section at the upper part of the silo main body. A guide rail is provided to separate the gate member from the lower end of the packet against an elastic body such as a coil spring installed in the cylinder.

An embodiment of the present invention will be described below based on the drawings.

Reference numeral 1 denotes an asphalt mixture silo body placed on a pedestal 2, which temporarily stores asphalt mixture manufactured by an asphalt plant (not shown) at a temperature of around 160°C. It has an input section 3 and a material discharge section 4 at the bottom.

Reference numeral 5 denotes a vertical conveyance device, in which a pair of guide rails 6 and 6, each of which has a sliding surface on the inner surface of a molded steel, are arranged facing each other at a predetermined distance from the ground surface to the material input section 3 on the upper part of the silo body 1. A roller 7.7°7.7. is provided and rotates in sliding contact with the sliding surface of the guide rail 6°6. One end of a cable 9 such as a wire rope is fastened to the asphalt mixture transport packet 8 which is rotatably arranged, and pulleys 10, 10.1 which are rotatably arranged.
The other end of the cable 9 is fastened to a winch 11 via the winch 11, and the packet 8 is raised and lowered in conjunction with the winding and unwinding of the cable 9 as the winch 11 rotates forward and backward.

The packet 8 has a material intake port 12 at the top and a discharge port 1 at the bottom.
It has 3.

Reference numeral 14 denotes a gate member that closes the opening of the discharge port 13, and is appropriately reinforced with shaped steel or the like and is attached to a support member 15 fixed to the packet side wall by a pivot pin 16 so as to be rotatable around the pin.

A cylinder 17 is attached to the side wall of the packet, and is equipped with a compressed coil spring 18. The restoring force of the coil spring 18 constantly presses the piston 19 and extends the piston rod 20.

The tip of the piston rod 20 is pivotally connected to an arm 21 provided on the gate member 14, and the restoring force of the coil spring 18 presses the arm 21 downward to move the gate member 14 to the discharge port using the pivot pin 16 as a fulcrum. It is always in pressure contact with the specified pressure.

22. Gate rollers 22 are rotatably provided on both sides of the gate member 14.

Reference numeral 23 designates a plate material erected on the gate member 14 to prevent materials from spilling and to guide the release of materials.

When a packet 8 ascends above the material input section 3 on the upper part of the silo main body 1, the gate rollers 22, 22 disposed on both sides of the gate member 14 of the packet 8 are guided to cause the packet 8 to fall downward, thereby removing the gate member. Guide rails 24 and 24 are provided for rotating the gate member 14 around the pivot pin 16 and separating it from the discharge port 13 against a coil spring 18 built into the cylinder 17 that biases the gate member 14 in the closing direction. It is set up.

The guide rail 24.24 is disposed on the track of the gate roller 22.22 of the packet 8 with the inner surface of the shaped steel serving as a sliding surface, and is approximately chevron-shaped so as to cause the gate roller 22.22 to fall downward. There is.

Reference numeral 25 denotes a horizontal conveyance device, which conveys asphalt mixture manufactured by an asphalt plant (not shown) to the vertical conveyance device 5 of the mixture silo, in which conveyance packets 27 reciprocate on horizontal rails 26. There is.

When the asphalt mixture manufactured by the asphalt plant (not shown) is put into the packet 27 of the horizontal conveyance device 25, the packet 27 travels on the horizontal rail 26 and directly above the packet 8 of the vertical conveyance device 5. The machine stops at , and the asphalt mixture is put into the packet 8.

The gate member 14 of the packet 8 is urged in the closing direction by the restoring force of a coil spring 18 compressed and installed in the cylinder 17 with a force that overcomes the weight of the asphalt mixture contained therein.

Next, the winch 11 is rotated in the forward direction to wind up the cable 9, and the roller 7 is placed on the inner sliding surface of the guide rail 6.6 made of shaped steel.
7. 7. The packet 8 is moved up while sliding and rotating the silo body 1, and when the packet 8 approaches the top of the silo body 1, the rotation of the winch 11 is reduced and the speed is gradually reduced while the packet 8 is ascended. 1, the gate rollers 22.22 of the gate member 14 are guided by the guide rails 24.24 disposed on the tracks of the gate rollers 22, 22 and fall downward. The gate member 1 resists the coil spring 18 of the cylinder 17 that presses and biases the gate member 14 in the closing direction.
4 rotates around the pivot pin 16, and the asphalt mixture slides down on the gate member 14 and is thrown into the silo main body 1.

On the other hand, the winding rotation of the cable 9 of the winch 11 is caused by the packet 8
In order to detect that the discharge port 13 of the silo body 1 faces the material input section 3 of the silo body 1, it is stopped by a signal from a detection means appropriately arranged.

When the discharge of the asphalt mixture is completed, the winch 11 is reversed and the packet 8 is lowered by its own weight, and the gate member 14 is restored to the position where the discharge port 13 of the packet 8 is closed.

As described above, the present invention presses the packet lower gate of the vertical conveyance device in the closing direction by the restoring force of the coil spring compressed and installed in the cylinder, and when the packet discharge port faces the material input port in the upper part of the silo body. Since the gate roller of the packet is guided to the guide rail to open the gate against the coil spring, the gate can be opened and closed without using pneumatic or hydraulic cylinders, so it can be used as a gate mechanism for packets transported over long distances. Beneficial.
