[0026] See also Figure 1 The two ends of the second crossbar 30 are respectively provided with connecting rods 31, and the connecting rods 31 on both sides are respectively connected to the longitudinal rods 21 on both sides. Through the above structure, the second crossbar 30 and the first crossbar 20 are connected to form an integrated structure.

[0028] The second cross bar 30 can be fixed by connecting the connecting rod 31 to the longitudinal rod 21 , or by welding the connecting rod 31 to the steel structure frame of the conveying device 10 .

[0029] See also Figure 2 ,3 The upper end of the push rod device 40 is hinged to the first cross bar 20 through the hinge seat 41; the lower end of the push rod device 40 is installed with a fisheye joint 42, and the third cross bar 50 is provided with a first double-ear hinge seat 43, and the fisheye joint 42 is hinged to the first double-ear hinge seat 43. Through the above structure, the push rod device 40 is hinged to the first cross bar 20 and the third cross bar 50.

[0030] Specifically, the articulated seat 41 includes a CA single-ear seat and a CB double-ear seat, and the CA single-ear seat and the CB double-ear seat are hinged by a pivot, see Figure 2 In the figure, the CB double-ear seat is connected to the first cross bar 20 by bolts, and the CA single-ear seat is connected to the push rod device 40 by bolts.

[0037] The action process or principle of the utility model is as follows:

[0038] After the phosphogypsum board is extruded and formed by the upper and lower rollers, it enters the conveying device of the phosphogypsum board production line. Since the pressure equalizing device of the utility model is installed at the front end of the conveying device 10, after the phosphogypsum board is manually pulled under the pressure equalizing wheel 60, the push rod device 40 is controlled to extend, and the pressure equalizing wheel 60 swings downward to squeeze the phosphogypsum board, thereby increasing the friction between the phosphogypsum board and the belt 12, so that the phosphogypsum board is closely attached to the belt 12 and moves synchronously with the belt 12. At this time, the phosphogypsum board is still an uncut long strip. When the phosphogypsum board is produced to a certain length, the friction between the phosphogypsum board and the belt 12 becomes larger. At this time, the push rod device 40 is controlled to shorten, and the pressure equalizing wheel 60 moves upward away from the phosphogypsum board, and the phosphogypsum board moves synchronously with the belt 12.
