[0023] For example, Figure 1The utility model discloses a conveying belt deviation rectifying device, including fixed frame 1, rotator 11, roller support 12, drum device, hydraulic pump, oil cylinder, rotator drive arrangement, pipe 6 and valve 7.

[0024] Rotator 11 is installed on fixed frame 1, and is rotatably connected with fixed frame 1, can rotate along the surface of fixed frame 1, and roller support 12 is fixed to one end of rotator 11;Drum device includes main roller 21 and side roller 22, and main roller 21 and side roller 22 are fixed on roller support 12, and side roller 22 is two, and is located on the both sides of main roller 21 respectively, and is arranged obliquely with main roller 21, and main roller 21 and side roller 22 are located in the same vertical plane, and main roller 21 is used for supporting the main body of belt 8, and the side roller 22 on both sides is used for supporting the left and right sides of belt 8, and the center line of drum device is the left-right symmetry axis of main roller 21, and the center line of belt 8 is the left-right symmetry axis;Rotator drive arrangement includes cylinder body 51 and piston rod 52, and cylinder body 51 is located on the side close to left side roller 22, and is fixed to fixed frame 1, and one end of cylinder body 51 is open, and the other end is closed, and one end of piston rod 52 can move as piston in cylinder body 51, and the other end of piston rod 52 is fixedly connected with one end of rotator 11.

[0025] Hydraulic pump includes left hydraulic pump 31 and right hydraulic pump 32, and is located behind two side rollers 22 respectively, and oil cylinder includes left oil cylinder 41 and right oil cylinder 42, and is communicated with left hydraulic pump 31 and right hydraulic pump 32 respectively;Left oil cylinder 41 and right oil cylinder 42 are all equipped with oil outlet and oil inlet, and each oil outlet and oil inlet is communicated with valve 7 through pipe 6 respectively, and valve 7 is also communicated to both ends of cylinder body 51.In this embodiment, the hydraulic pump is drum type pump, and the drum type pump includes rotor, when belt 8 is offset and rubs hydraulic pump, drives the rotation of rotor, and then makes the drum type pump pump high pressure oil in oil cylinder.

[0026] When high pressure oil is pumped out from the oil outlet of left oil cylinder 41, is delivered to valve 7 by pipe 6, adjusts the flow direction through valve 7, enters the open end of cylinder body 51, and high pressure oil flows from the open end to the closed end in cylinder body 51, then flows into valve 7, adjusts the flow direction through valve 7 again, and enters the oil inlet of left oil cylinder 41;When high pressure oil is pumped out from the oil outlet of right oil cylinder 42, is delivered to valve 7 by pipe 6, adjusts the flow direction through valve 7, enters the closed end of cylinder body 51, and high pressure oil flows from the closed end to the open end in cylinder body 51, then flows into valve 7, adjusts the flow direction through valve 7 again, and enters the oil inlet of right oil cylinder 42.

[0027] The belt 8 moves forward along the belt movement direction 81.

The high-pressure oil is delivered to the valve 7 through the conduit 6 connected to the oil outlet of the left oil cylinder 41. Then, the flow direction is adjusted by the valve 7 and it enters the open end of the cylinder 51, causing the piston rod 51 to retract. The retraction of the piston rod 51 drives the rotating part 11 to rotate clockwise, which in turn drives the roller support 12 and the roller device to rotate clockwise. The center line of the roller device shifts to the left and aligns with the center line of the belt 8. After the center line of the belt 8 is aligned with the center line of the roller device, the left side roller 22 lifts the belt 8. The belt 8 no longer rubs against the left hydraulic pump 31, and the left hydraulic pump 31 stops working. The high-pressure oil in the cylinder 51 flows out from the closed end and returns to the valve 7. The flow direction is adjusted by the valve 7 and it is delivered to the oil inlet of the left oil cylinder 41 through the conduit 6. At the same time, the piston rod 51 extends and resets, driving the roller device and the belt 8 to reset, completing one belt correction cycle. Similarly, the opposite occurs when belt 8 shifts to the right.
