The present invention relates to a circular hopper gate device of an unloader for unloading transported goods such as raw and fuel of a steel mill, and more particularly, a circle of a steel mill discharged from a ship shipped through a continuous unloader. Knitting, knitting, and uneven dispensing generated when the fuel falls into the rotary belt conveyor through the circular hopper of the unloader are controlled, thereby enabling uniform dispensing while preventing meandering from the belt conveyor. The present invention relates to a circular hopper gate device of an unloader that can prevent various troubles, belt damage, and the like.

Raw and fuel used in steel mills, namely iron ore and coal, are usually transported to ships and unloaded at the pier. UNLOADER is used to unload and discharge the fuel and raw materials of such ships. It is shown in 1.

That is, as shown in Figure 1, the unloader, in particular, the continuous unloader 100, which is a continuous discharge of transport, such as a circle, fuel, etc., the running unit 110 is moved along the pier ship holding ( 120, the fuel is unloaded, the bakett 142 of the bakett elevator post 140 installed on the boom 130 above the running portion 110 enters the hold 120 of the vessel 150, The fuel is moved up and down using the bucket elevator to move to the circular hopper 160 through the boom belt conveyor.

On the other hand, as shown in Figures 1 and 2a, the circle, fuel 170 moving through the boom belt conveyor is loaded in a circular hopper 160 that can easily collect them, then the lower rotary belt conveyor 190 When disbursed by), the ground belt conveyor 180 is connected to the ground belt conveyor 180, and the discharging is carried out through the unloading of the transport 170 such as raw fuel and the belt conveyor.

However, the circular hopper 160 is not provided with a separate damper, such as a rectangular hopper installed between the normal belt conveyor, when the drop down to the rotary belt conveyor 190 through the circular hopper 160 The dispensing amount is not adjusted, and the driver adjusts the amount carried on the 68 baquets 142.

However, since it is difficult to control the discharge amount of the transport material 170 such as raw and fuel through the 68 bagets 142, the discharge amount is not constant as shown in FIGS. 2B and 2C. In particular, when the transport 170 falls to the belt 192 of the rotary belt conveyor 190 below the circular hopper 160, the transport 170 is on one side on the belt 192 of the rotary belt conveyor 190. Knitting and knitting phenomenon that falls while biased is easily generated.                         

As a result, such a transport pile of the rotary belt conveyor 190 causes meandering of the rotary belt conveyor 190, so that a problem of falling of the transport object without being linked to the ground belt conveyor 180 is generated, This causes a problem of additionally causing environmental pollution due to falls.

In addition, when the knitting is continuously generated, there are various problems such as damage to the belt 192 of the rotary belt conveyor 190 at an early stage, and the dispensing amount thereof may not be kept constant.

Therefore, if the unloaded circular hopper adjusts the load of the transport immediately after the drop of transport such as circle or fuel by the rotary belt conveyor, it prevents meandering of the rotary belt conveyor afterwards, and afterwards, it is desirable to allow smooth transportation through the ground belt conveyor. will be.

Is connected through the hinge pin (63) rotatably, the hinge bar (62b) and the third operating arm (64) is interlocked with the hinge pin (63) as the axis when the cylinder 62 is operated, and The third working arm 64 moves as the arc-shaped raceway about the lower second rotational axis 70 as an axis, and eventually the transport on the belt 24 is moved integrally with the gate 66 in the arc-shaped raceway. Flatten out 30).

In this case, the gate 66 is schematically illustrated in the drawing, but is formed in an arc shape so that the gate 66 is guided toward the center of the belt 24 when the transportation object 30 is adjusted.

In addition, although not shown in the drawings, the hydraulic unit for driving the cylinder 62 is electrically connected to the control panel or the control panel of the unloader cab for driving the apparatus 1 of the present invention, the control panel is Sensor operating arms 46 which are electrically connected to the sensors 44a, 44b and 44c so that the sensors 44 integrally move along the guide roll 48 which moves in contact with the shipment 30. , The hydraulic unit drives the cylinder 62 to adjust the drive stroke of the cylinder 62 and adjusts the rotational movement of the gate 66 according to the operation. The gate 66 is configured to variably move in accordance with the belt loading state of.

The third actuating arm 64 of the shipment adjusting unit 60 is a vertical bar 64a on a second rotating shaft 70 provided to rotate in a bearing block 68 provided on the cover 22. Are connected as.

Further, the gate 66 is vertically fixed to the end of the connecting bar 72 horizontally fixed to the third working arm 64, and is formed to round. In particular, as shown in FIG. The lower end 66a of the 66 is arranged to extend lower than the guide roll 48 when the guide roll 48 is positioned at the lowermost portion so that the transport 30 on the belt 24 can be more evenly developed. Consists of.

At this time, the cover 22 has a configuration in which the opening 22c through which the gate 66 passes through is integrally formed.

Referring to the operation of the present invention made in the above configuration in detail as follows.

As shown in Figures 3 to 5, a continuous unloader having a baggage for loading and unloading the transport material loaded on the vessel, for example, iron ore and coal used as raw and fuel in the steel mill. Is installed on the rotary hopper 10 and the rotary hopper 10 is installed on the lower side of the rotary belt conveyor 20 to distribute the transport material 30 dropped through the circular hopper 10 to the ground belt conveyor through the circular hopper 10 Circular hopper of the unloader of the present invention to uniformly spread the transported material 30 on the belt 24 of the rotary belt conveyor 20 to prevent the meandering of the belt 24 ultimately. The gate device 1 is as follows.

First, as shown in FIG. 4, the transport material, that is, iron ore or coal 30, which is raw or fuel of the steel mill, is dropped on the belt 24 of the rotary belt conveyor 20 through the circular hopper 10. When loaded, the guide roll 48 of the lower portion of the second operating arm 42b inserted through the upper cover 22 of the conveyor 20 is in contact with the belt 24 being transported in accordance with the transfer.

Accordingly, the guide roll 48 is lifted upwards as the transport height 30 loaded on the belt 24 is pushed to one side according to the loading state, for example, when it is stacked or dropped, and the loading height is higher. As a result, the movement of the second operation arm 42b, the first rotary shaft 52, the first operation arm 42a, and the sensor operation arm 46 proceeds in order, and the sensor operation arm 46 moves on the bracket 45. The sensor 44a, 44b, 44c is operated while being positioned adjacent to any one of the plurality of sensors 44 arranged in an arc in accordance with the movement path of the sensor operation arm.

Accordingly, the hydraulic unit electrically connected to the sensors 44 reverses the rod of the cylinder 62 with a predetermined stroke and slidably engages the hinge pin 63 as the long groove 62b 'to be rotatable with the rod. The third operating arm 64 is pulled into the arc orbit around the second rotation shaft 70 through the vertical bar 64a integrally with the hinge bar 62b connected to each other.
Thus, the gate 66 connected as the connecting bar 72 to the third actuating arm 64 is transported on the belt 24 of the rotary belt conveyor 20 with its lower end 66a descending. 4 and 5, uniformly developed to control the loading of the transport onto the belt 24 or to one side, wherein the gate 66 has a concave arc centered in plan view. It may be desirable to form the gate 66 to guide the shipment 30 further inward, ie toward the center of the belt 24.

Accordingly, when the transport object 30 is loaded onto the belt 24 of the rotary belt conveyor 20 through the circular hopper 10 which does not have a damper to control the drop of the transport object, the load is detected and correspondingly As the descending gate 66 unfolds the transport 30 on the belt 24, the meander of the belt 24 due to the transported material being stacked or the transport 30 are scrapers 22a on both sides of the cover 22. It is to prevent falling to the outside through).

As described above, according to the circular hopper gate device of the unloader of the present invention, when a transport such as raw or fuel used in an ironworks factory is unloaded from a ship of a pier, the transport is a rotary belt in a circular hopper of a continuous unloader which is an unloader. By distributing the transport uniformly within a short time on the upper surface of the rotary belt conveyor at the moment of dispensing into the conveyor, it is possible to effectively prevent the meandering of the belt conveyor by adjusting the knitting and knitting of the transport falling from the hopper.

Therefore, the fall of transport goods due to meandering of the belt conveyor is blocked to prevent the environmental pollution by the fall, while preventing the equipment damage such as the belt damage due to the meandering, and in the severe case, the equipment shutdown such as stopping operation of the belt conveyor. It is to provide an excellent effect to enable more smooth transport of the transport to improve the productivity of the operation.

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below. I would like to know that those who have knowledge of this can easily know.
