By being able to selectively transfer to 5b and 5c, such a belt conveyor 100 is composed of a main body portion 10, a pulley portion 30 and an operation portion 50 and the like.

That is, the main body portion 10 for horizontally moving the tripper chute 11 on the charging lines 5a, 5b, 5c is a belt member 11 which is circulated in an endless track at the bottom of the mixing tank 1. The pulley chute 12 is disposed on the head pulley 11a of the ts so as to drop the transported material transported by the belt member 11 downward, and a tail pulley installed at the rear end of the belt member 11. 11b is provided with a weight (19a) connected to it is provided with a tension maintaining tension tower 19 for maintaining the tension of the belt member (11).

In addition, the tripper chute 12 is fixedly installed at the front end of the main body frame 13 on which the left and right ends of the head pulley 11a are rotatably assembled, and the main body frame 13 is the charging line 5a ( It is assembled so as to be movable horizontally by the rotational driving force of the first motor 14 on the fixed rail 13a horizontally installed on 5b) (5c).

The main body frame 13 is a skeletal structure composed of a plurality of upper and lower horizontal bars 15a and 15b and a vertical bar 15c, and is mounted on the fixed rail 13a on the lower horizontal bar 15b. A plurality of moving wheels 16 are assembled, and one moving wheel 16 is equipped with a driven gear 16a geared with the drive gear 16b of the first motor 14. Accordingly, the main body frame 13 may be horizontally moved forward and backward on the fixed rail 13a according to the forward and reverse rotational driving of the first motor 14.

In addition, the pulley part 30 to which the belt member 11 traveling between the head and the tail pulleys 11a and 11b is wound is horizontally moved at the left and right ends on the middle horizontal bar 15d of the main body frame 13. It is equipped with a second motor 32 for horizontally moving the movable pulley 31 to be assembled, and the left and right ends are rotatably assembled on the fixed pair of fixed pulley base 33a via the bearing member 33b. A fixed pulley 33 is provided and configured.

Here, the movable pulley 31 is rotatably assembled to the left and right ends of the movable trolley 34 via the bearing member 34a so that the movable pulley 31 can be moved forward and backward with respect to the fixed pulley. The plurality of moving wheels 35 mounted on the left and right sides are arranged to travel along the upper and lower rails 35a and 35b provided inside the middle horizontal bar 15d of the main body frame 13. The rack gear 36a mounted on the upper surface of the intermediate horizontal bar 15d and the pinion gear 36 geared to each other are assembled to the drive shaft of the second motor 32.

Accordingly, according to the forward and reverse rotational driving of the second motor 32, the movable pulley 31 can be reduced or widened while running along the upper and lower rails 35a and 35b with respect to the fixed pulley. It is.

On the other hand, the control unit 50 is the charging line (5a) (5b) (5c) to detect the position of the tripper chute 12 is moved back and forth when the first and second motors (14, 32) are rotated Sensor members 51a, 51b, 51c which are fixedly installed at positions corresponding to the tripper chute 12 and generate detection signals when they correspond to the tripper chute 12, and the sensor members 51a, 51b, 51c The moving wheel 16 is fixedly mounted at a predetermined interval on the inner surface of the fixed rail 13a on which the moving wheel 16 runs, with the same interval as the installation interval between the centers of the charging lines 5a, 5b and 5c.

Then, the controller 53 is configured to control the rotational driving of the first and second motors 14 and 32 by the detection signals detected by the sensor members 51a, 51b and 15c.

3 and 7, reference numeral 11c is a band pulley 11c for guiding the circulation of the belt member 11, 18a is a carrier roller, and 18b is a return roller.

The operation and effects of the present invention having the configuration as described above will be described.

First, as shown in FIG. 3, the tripper chute 12 provided in the head pulley 11a of the belt member 11 circulated to convey the transported substance discharged from the mixing tank 1, as shown in FIG. By moving the position on the 5a) to the second charging line (5b), if you want to transport a transport such as ore dropping through the tripper chute 12 to the post process through the selected charging line (5b), the control unit ( An external power is supplied to the first and second motors 14 and 32 through the controller 53 of 50 to rotate each drive shaft.

In this case, when the driving gear 16b of the first motor 14 and the driven gear 16a of the driven wheel 16 geared are rotated in the forward direction and counterclockwise in the drawing, the lower part of the main frame 13 Since the moving wheel 16 mounted on the left and right sides of the horizontal bar 15b and mounted on the fixed rail 13a is rotated in the forward direction to move the cloud, the entire body frame 13 is horizontally moved from right to left. You can.

At the same time, when the rack gear 36a mounted on the middle horizontal bar 15d of the main body frame 13 and the pinion gear 36 of the second motor 32 geared to each other rotate in the forward direction, The moving cart 34 which has the 2nd motor 32 fixed and the moving wheel 35 between the upper and lower rails 35a and 35b arrange | positioned inside the said intermediate horizontal bar 15d is shown in figure. Since it is horizontally moved from right to left, the moving pulley 31 whose left and right ends are rotatably assembled to the moving trolley 34 with respect to the fixed pulley 33 having both left and right ends assembled to the fixed pulley base 33a. By horizontally moving to the side, the gap between the fixed and movable pulleys 31 and 33 can be narrowed.

That is, the moving pulley 31 moves a predetermined distance by the rotation driving force of the second motor 32 by a predetermined amount of movement of the main body frame 13 by the rotation driving force of the first motor 14. It is possible to compensate for the length of the belt member 11 is wound around the head, the movement, fixing and the tail pulley (11a) (31) (33) (11b).

At this time, since the weight 19a is suspended in the weight direction through the wires 19c wound on the plurality of turning wheels 19b in the tail pulley 11b, the tension of the belt member 1 is increased. Regardless of the horizontal moving distance of the main body frame 13 and the moving pulley 31, it can always be kept taut.

Continuously, when the tripper chute 12, which is horizontally moved from right to left by the driving force of the first motor 14, is hidden in the sensor member 51b installed to correspond to the second charging line 5b, the detection signal is detected. Is transmitted to the controller 53 to stop the rotational driving of the first and second motors 14 and 32.

On the other hand, when the tripper chute 12 is moved on the third charging line 5c due to the change in the working conditions, and the conveying work is to be carried out, the first and second motors 14 and 32 are simultaneously moved. By rotating in the forward direction, the tripper chute 12 is moved horizontally until it is detected by the third sensor member 51c, and the distance between the movable pulley 31 and the fixed pulley 33 is further narrowed. On the contrary, in order to return the tripper chute 12 to the first charging line 5a, the first and second motors 14 and 32 are rotated in the reverse direction by the controller 53. The body frame 13 is horizontally moved from the left side to the right side along the fixing rail 13a, and the movable pulley 31 is also returned backward so that the distance between the movable pulley 31 and the fixed pulley 33 is increased. Make it happen.

According to the present invention as described above, since the belt member is arranged in a straight line at the bottom of the mixing tank, the transporter can be selectively carried out by horizontally moving the tripper in accordance with the charging line, so that the goods can be transported to various places even in a narrow space. Can be supplied smoothly, and the tension tower is installed on the tail part to keep the tension of the belt member constant by reducing it compared to the conventional one, and to reduce the drop of the chute to prevent the occurrence of sticking coal in the tripper chute. It prevents the pollution of the surrounding environment by suppressing the occurrence.

In addition, since the belt conveyor line provided at the bottom of the mixing tank can be simplified, the effect of efficient facility management and reduction of facility maintenance costs can be obtained.

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 clarify that knowledge is easy to know.
