(2) setting a deviation threshold value, wherein a first deviation threshold value a is 20mm, and a second deviation threshold value b is 80 mm;
(3) detecting offset, specifying that the offset to the left side of the initial central line is a negative value and the offset to the right side of the initial central line is a positive value, detecting the displacement difference between the central line of the material receiving frame and the central line of the belt frame extension assembly device and two sides of the roadway in real time by using a laser ranging sensor and an inclination angle sensor, calculating and determining the offset distance of the initial central line, and recording the offset of the central line of the material receiving frame as X1The offset of the central line of the belt frame extension assembling device is X2；
(4) The controller compares the offset with the offset threshold value, and makes a corresponding offset action command when-a<X1<When a, the material receiving frame does not need to perform deviation adjustment, and the step 3 is repeated; when-a<X2<When a, the belt frame extension assembling device does not need to perform deviation adjustment, and the step 3 is repeated;
(5) implementing deviation adjustment of the material receiving frame: when-b<X1<A or a<X1<b, the material receiving frame front deviation adjusting oil cylinder (451) and the material receiving frame rear deviation adjusting oil cylinder (461) act until the central line of the material receiving frame is superposed with the initial central line; when X is1<-b or X1>b, the material receiving frame front deviation adjusting oil cylinder (451) and the material receiving frame rear deviation adjusting oil cylinder (461) are reset to the middle position, and the left traveling mechanism and the right traveling mechanism (31) act until the material receiving frame central line deviation X1To within + -a;
(6) implementing deviation adjustment of the belt frame extension assembling device: when-b<X2<A or a<X2<b, the clamping deviation-adjusting oil cylinder (731) acts until the central line of the belt frame extension assembly device is superposed with the initial central line; when X is present2<-b or X2>b, the clamping deviation-adjusting oil cylinder (731) is reset to a middle position, the deviation-adjusting oil cylinder (6) of the extension assembling device acts until the deviation X of the central line of the belt frame extension assembling device2To within + -a;
the belt deviation adjustment is completed by adjusting the angle of a tail roller through a belt deviation adjustment oil cylinder I (43) and a belt deviation adjustment oil cylinder II (44), and the method specifically comprises the following steps:
(A1) triggering the deviation switches arranged on the two sides of the belt frame (81) once every 10 seconds to detect whether the belt (5) deviates;
(A2) when a deviation switch signal is detected, the belt deviation adjusting oil cylinders I (43) and II (44) on the two sides of the tail roller act until the deviation switch is not triggered any more, and the automatic deviation adjustment of the belt (5) is realized.
