Abstract
The utility model belongs to the technical field of strip mine belt transportation, a strip mine belt conveyer aircraft nose chute device is disclosed, through changing material whereabouts mode (become the mode along the chute landing from the free fall), with the more problem of open-pit mine raise dust in the transportation among the solution prior art, the device is including fixing the pivot in belt feeder aircraft nose bottom, movable mounting has the rock discharge chute in the pivot, the material of belt feeder transportation can fall into in the rock discharge chute, and the rock discharge chute can revolute the rotation of axes, be equipped with chute lifting hydraulic cylinder between the bottom of rock discharge chute and the belt feeder aircraft nose bottom. The utility model discloses an open-pit mine belt conveyor aircraft nose chute device is through adopting the rock discharge chute rock discharge, has realized that the material becomes along chute swift current row by throwing, the production volume of raise dust when the ground that has significantly reduced discharges. The utility model has the advantages of being simple in structure and convenient in operation, can effectively reduce the production of rock discharge in-process raise dust.
Description
Technical Field
The utility model relates to a strip mine belt transport technical field, concretely relates to strip mine belt conveyor aircraft nose chute device.
Background
In winter, due to the fact that the temperature of the northern open-pit mine is low, sprinkling can not be used for dust reduction, the raised dust in the rock discharging process of the open-pit mine can not meet the national emission standard of air pollutants, under the background that the environmental protection requirement is increasingly strict, how to reduce the raised dust in the rock discharging process of the northern open-pit mine in winter is particularly important, and the technical problem can not be solved in the prior art.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problem that the raise dust is more in the rock discharging process of the strip mine in the prior art, and providing an open mine belt conveyor head chute device with simple operation and simple structure.
The technical principle is that the problem that in the prior art, the strip mine raises more dust in the rock discharging process is solved by changing the falling mode of materials (changing from a free falling body to a mode of sliding along a chute).
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an opencast ore belt conveyor aircraft nose chute device, is including fixing the pivot in belt conveyor aircraft nose bottom, and movable mounting has the rock discharge chute in the pivot, and the material of belt conveyor transportation falls into the rock discharge chute, and the rock discharge chute can revolute the rotation of axes, is equipped with chute lifting hydraulic cylinder between the upper portion bottom surface of rock discharge chute and belt conveyor aircraft nose bottom.
Furthermore, the rock discharging chute is a trapezoidal chute, the width of the bottom of the rock discharging chute is 1.2-1.4 m, and the width of the opening of the rock discharging chute is 1.6-1.8 m.
Further, the height of the lateral wall of the rock discharge chute is 0.4m-0.5 m.
Furthermore, the thickness of the side wall and the bottom of the rock discharge chute are both manganese steel plates with the thickness of 30 mm.
Compared with the prior art, the utility model, following beneficial effect has:
the utility model discloses an open-pit mine belt conveyor aircraft nose chute device is through adopting the rock discharge chute rock discharge, has realized that the material becomes along chute swift current row by throwing, the production volume of raise dust when the ground that has significantly reduced discharges. Through adopting the motor to drive lifting hydraulic cylinder, realized the angle change of dumping chute, the dumping chute automatic rising, along with the dumping on the dump slope rock pile height gradually, promote the dumping chute step by step through hydraulic cylinder, guarantee that the dumping is smooth and easy. And repeating the steps until rock discharging is finished. The utility model has the advantages of being simple in structure and convenient in operation, can effectively reduce the production of rock discharge in-process raise dust.

Fig. 2 is an enlarged schematic view of the rock discharge chute of the present invention.
Figure 3 is the front view of the rock discharging chute of the utility model.
The reference numerals have the following meanings: 1. a rock discharge chute; 2. a rotating shaft; 3. a chute lifting hydraulic oil cylinder; 4. a belt conveyor; 5. a belt conveyor head; 6. a dump side slope.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
As shown in fig. 1-3, the machine head chute device of the strip mine belt conveyor comprises a rotating shaft 2 fixedly welded at the bottom of a belt conveyor head 5, a rock discharge chute 1 is movably installed on the rotating shaft 2, the rock discharge chute 1 is a trapezoidal chute, the width of the bottom of the rock discharge chute 1 is 1.2-1.4 m, and the width of an opening of the rock discharge chute 1 is 1.6-1.8 m. The height of the side wall of the rock discharge chute 1 is 0.4m-0.5m, and the thickness of the side wall and the bottom of the rock discharge chute 1 are both manganese steel plates with the thickness of 30 mm.
The pivot 2 can be whole root axle, also can be the axle of middle part disconnection, when pivot 2 is whole root axle, the upper portion dress of rock discharge chute 1 is in pivot 2, and can revolute 2 rotations of axle, when pivot 2 is two axles of middle part disconnection, the tip of pivot 2 is articulated with rock discharge chute 1's upper portion both sides, and can revolute 2 rotations of axle, the material of belt feeder 4 transportation falls into rock discharge chute 1 along with the belt transportation in, and rock discharge chute 1 can revolute 2 rotations of axle, be equipped with chute lift hydraulic cylinder 3 through the bolt-up between rock discharge chute 1's the upper portion bottom surface and the belt feeder aircraft nose 5 bottoms.
During operation, the ore rock that belt feeder 4 was carried passes through the rock discharge chute 1 rock discharge, has realized that the material becomes the rock discharge chute 1 swift current row by the throwing, the production volume of raise dust when the ground discharges has significantly reduced. Through the effect of chute lift hydraulic cylinder 3, realized the angle change of rock discharge chute 1, rock discharge chute 1 automatic rising, along with rock pile height gradually on the refuse dump slope, rock discharge chute 1 is progressively promoted through lift hydraulic cylinder 3, guarantees that the rock discharge is smooth and easy. And repeating the steps until rock discharging is finished.
