Abstract

(57) Abstract: An object of the present invention is to prevent scattering of dust when a bulk material is discharged from a hopper to a vehicle. A vertically movable chute provided at a payout opening of a hopper and a counter weight disposed long in the horizontal direction are suspended via two ropes. The counter weight 44 is a cylinder device 43
To go up and down. The weight of the counterweight 44 is substantially the same as the weight of the chute 40b suspended by the rope 45. The chute 40b is lowered by the cylinder device 43 when the bulk material is paid out to the vehicle 100. At this time, scattering of dust can be suppressed. Since the weights of the two are almost the same, the cylinder device 43 can be made smaller.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for discharging bulk materials such as coal from a hopper to a vehicle.

[0002]

2. Description of the Related Art A hopper accumulates bulk materials such as coal. The hopper is opened at a lower gate and dropped into a vehicle to be dispensed.

[0003]

When dispensing to a vehicle, dust is scattered because the loose objects fall at one time.

An object of the present invention is to reduce scattering of dust when dispensing to a vehicle.

[0005]

An object of the present invention is to provide a hopper with a vertically movable chute provided at a dispensing opening of a hopper, a counterweight arranged long in the horizontal direction, and a counterweight connected to the counterweight for raising and lowering the counterweight. And a rope connecting the counterweight and the chute via a sheave installed on the member on which the hopper is installed. The rope has two ropes, and the counterweight has a horizontal direction. This is achieved by connecting each end to each horizontal end of the chute.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 and FIG. 2 show an embodiment of the present invention.
This will be described below. In this embodiment, a hopper installed on a crane pays out to a vehicle.

In FIG. 2, the seaside leg 1 of the crane 10 is shown.
A hopper 20 is provided between the hopper 1 and the leg 12 on the land side.
The bulk material discharged from the ship by the bucket 15 of the crane 10 is put into the hopper 20. The loose material of the hopper 20 passes through the gates 23b and 23c, and
b, enter 30c. It is paid out to the vehicles 100, 100 traveling below through the gates 31b, 31c below it. The vehicle 100 travels along the traveling direction of the crane 10. When a predetermined amount of bulk material is stored in the hoppers 30b and 30c, the gates 23b and 23c are closed.

The hopper 30b is located on the land side of the hopper 30c. The hopper 30b and the hopper 30c are installed in parallel. The interval between the hoppers 30b and 30c is
Are the intervals at which the vehicle can be stopped and run in parallel. For this reason, the interval between the entrances of the hoppers 30b and 30c is small, but the interval between the exits at the lower ends is wide. The interval between the hoppers 30b and 30c increases toward the outlet.

Each of the hoppers 30b and 30c has a bulk storage capacity for one vehicle 100. The bulk storage capacity of the hopper 20 is equivalent to a plurality of vehicles 100.

The hopper 20 is suspended from the cross beam 13 of the crane 10. Hoppers 30b and 30c are hopper 2
It is suspended from 0 through a member 29.

The lower end of the hopper 20 has two payout ports, each of which has a gate 23b and 23c. The hopper 23b is on the land side of the hopper 23c. Hopper 2
3b and 23c are parallel to each other.

The entrances of the hoppers 30b and 30c are located below the respective payout ports opened and closed by the gates 23b and 23c. When the gate 23b is opened, loose materials are supplied to the hopper 30b. When the gate 23c is opened, the hopper 30c
The bulk is supplied.

The chutes 40b, 40c are located below the payout gates 31b, 31c at the lower ends of the hoppers 30b, 30c.
c is installed. The chutes 40b and 40c connect the payout port and the vehicle, and have lower ends provided to be able to move up and down. The chutes 40b and 40c are suspended from the member 29.

Referring to FIG. 1, the chute 40b will be described. The same applies to the configuration of the chute 40c. The chute 40b connects a plurality of cylinders 41b, 41c, 41d. The lower cylinder 41b (41c) is the upper cylinder 41
It can be hung at the lower end of c (41d) and does not come off. The lower cylinder 41b (41c) is the upper cylinder 41c.
(41d) It can move up and down. The same applies to the relationship between the uppermost cylinder 41d and the lower end of the hopper 40b.

A driving cylinder device 43 is installed on the member 29 in the vertical direction. The cylinder device 43 suspends the counterweight 44. The counterweight 44 is guided up and down by a plurality of vertical rails 45. Two ropes 45 connected to the counterweight 44 suspend the lower end tube via a plurality of sheaves.

The arrangement of the rope 45 will be described. The rope 45 fixed to the member 29 includes a sheave 52 at the horizontal end of the counterweight 44, a sheave 29 of the member 29 above the sheave 52, and a sheave 5 above the chute 40b.
3. Sheave 5 at the end of chute 41b at the lower end toward water
4 and 55 sequentially, the member 29 above the sheave 55
It is fixed to. A rope is hung a plurality of times between the sheave 52 and the sheave 51 to secure a necessary amount of elevating the chute.

The weight of the counterweight 44 is
5 is almost the same as the weight of the suspended chute 40b.

In such a configuration, the grab bucket 15
The loose objects are put into the hopper 20 from the ship. When the gates 23b and 23c of the hopper 20 are opened, the gates 33b and 33c of the hoppers 30b and 30c below the gate are closed. When the gates 23b and 23c are opened, the hopper 30
Bubbles are supplied to b and 30c. Hoppers 30b, 30
When a predetermined amount (one vehicle) accumulates in c, the load meter detects it and closes its own gate 23b, 23c. In principle, the gates 23b and 23c open alternately,
It is stored alternately in the hoppers 30b and 30c. And it pays out to the vehicle 100 alternately.

Hoppers 30b and 3 storing a predetermined amount of bulk materials
When the vehicle 100 stops below 0c, the stopped vehicle 1
Lower the hopper chute above 00. The lower cylinder 41b is located near the bed of the vehicle 100. This is performed by injecting oil into the cylinder device 43. Next, the gate of the hopper is opened, and the bulk is dispensed. Raise the chute before starting the vehicle. This is performed by discharging the oil from the cylinder device 43 and using the counterweight 44 as power. These operations are performed by workers.

According to this, since the dust is covered with the chute, scattering of dust can be suppressed. Also, the counter weight 44
And the weight of the chute 40b are almost the same,
The power of the cylinder device 43 can be reduced. Since the chute is raised by the counter weight 44, the chute can be raised even when the hydraulic system is called.

In the above embodiment, the hopper 30b having the chute 40b is provided below the hopper 20 for receiving the bulk material from the grab bucket 15, but the hopper 20 and the hopper 30b
The same applies to those having a vibration feeder and a conveyor between them.

In the above embodiment, the hoppers 20, 30b, 30
Although the dispensing device of c is suspended from the crane 10, the device may travel on the traveling road surface of the vehicle. In this case, since the size of the vehicle in the width direction cannot be increased, the hoppers 30b and 30c are preferably provided at the front and rear in the traveling direction of the vehicle.

The technical scope of the present invention is not limited to the language described in the claims or the language described in the section for solving the problems, and is easily replaced by those skilled in the art. It extends to a range.

[0024]

According to the present invention, it is possible to suppress scattering of dust when dispensing loose objects from a hopper to a vehicle.
