JPS5852909B2 - Drainage gutter for hopper gate - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drainage gutter that is provided below a hopper for storing moisture-containing materials and receives water leaking from between a pair of gates and the materials, and particularly relates to a drain gutter that is provided below a hopper that stores materials to be handled containing moisture. and a drainage gutter for a hopper gate suitable for discharging handled materials.

Generally, in a hopper that stores materials containing moisture, it is difficult to prevent moisture and the material being handled from dripping from the mating surfaces of a pair of gates provided at the bottom of the hopper.
For this reason, it is customary to provide a bowl-shaped drainage gutter on one of the gates to receive the dripping water and the material to be handled.

The gate drainage gutter described in Japanese Patent Publication No. 53-13871 is not reliable because the gutter tilts passively due to the gutter's own weight, and the gutter tilt angle is 90 degrees or less.
It is not possible to completely drain the water and the material being handled.

The present invention was devised in order to solve these conventional difficulties, and its purpose is to provide a drainage system for hopper gates that can completely drain the water and materials in the drainage gutter when the gate is opened. Gutters are provided.

In the present invention, a gutter support bracket is swingably attached to a bracket protruding from the lower end of one gate via a pin,
The lower end of the link is swingably supported at a position below the pin of the gutter support bracket, and the upper end of the link is swingably supported between the swinging centers of both gates to open the gate. In this case, the drain gutter is configured so that it can be rotated 180 degrees to completely drain the water inside the drain gutter.

The present invention will be described below based on an illustrated embodiment.

In FIG. 1, reference numeral 1 denotes a pair of gates disposed at the lower end of a hopper 2, and this gate 1 is pivotally connected to the hopper 2 via a pin 3.

The hopper 2 is configured to swing in opposite directions about the pin 3 by operating a piston rod 6 of a hydraulic cylinder 5 connected via a pin 4.

At the lower end of one gate 1, a bracket 7 is provided to protrude downward as shown in the figure, and at the lower end of this bracket 7, a support bracket for a bowl-shaped drainage gutter 9 is connected via a pin 8. 10 is swingably attached.

As shown in FIG. 1, the drain gutter 9 is configured to be placed below the abutting portion of the gate 1 when the gate 1 is closed.

As shown in the figure, the lower end of a link 12 is swingably attached to the support bracket 10 at a position below the pin 8 via a pin 11, and the upper end of this link 12 is mounted oppositely from the pin 3. It is swingably supported via a pin 13 by a bracket 14 that protrudes in the direction of the other pins 3 .

The length A of the link 12 is configured to be larger than the distance B from the pin 3 to the pin 8.

When the piston rod 6 of the hydraulic cylinder 5 is operated in the above configuration, the mutual gates 1, 1 swing away from each other around the pins 3, 3, and as shown in FIG. It will be released.

At this time, the length A of the link 12 is greater than the distance B from the pin 3 to the pin 8, so the drain gutter 9 rotates 180 degrees as shown in FIG. When the drain gutter 9 reaches the upper part, the water and the handled material are completely drained away.

As explained above, according to the present embodiment, the drain gutter rotates 180 degrees in conjunction with the opening operation of the gate, so that the water and objects in the drain gutter can be completely drained without requiring any human power.

In the above embodiment, the case where the bracket 14 is attached to the gate 1 has been described, but the present invention is not limited to this.
The drainage gutter may be installed at a rotation angle of 180i or more, as long as the water inside can be completely drained.
It may be 80 degrees or less.

The present invention has been described above based on the preferred embodiments, and according to the present invention, water and objects in the drain can be completely drained when the gate is opened.
