For the pulley assembly 18 described above, in addition to the above-mentioned combination of the existing fixed pulleys and even the movable pulleys, the following structure can be adopted for design:

as shown in fig. 13-14, the pulley assembly 18 of this embodiment includes a cylindrical body 1801 and at least 4 rolling bearings 1802, and theoretically the number of rolling bearings 1802 corresponds to the number of arc-shaped sheets 3031. The axial direction of the body 1801 is provided with a shaft hole, the contour line of the longitudinal section of the shaft hole is hyperbolic, the outer cylindrical surface of the body 1801 is provided with at least two annular caulking grooves 1805, each caulking groove 1805 is embedded with a rolling bearing 1802, the outer ring of the rolling bearing 1802 can rotate freely, the outer cylindrical surface of the outer ring is provided with a wire slot 1806 coaxial with the outer ring, and the wire slot 1806 is used for the steel wire 922 to pass around; two circular mounting grooves 1803 are arranged at the center of the upper part of the hole wall of the shaft hole, a convex column 1804 coaxial with the mounting groove is fixed at the center in each mounting groove 1803, the inner ring of a rolling bearing 1802 is fixedly sleeved on the convex column 1804, so that the outer ring of the rolling bearing 1802 can rotate freely, and the outer cylindrical surface of the outer ring is also provided with the wire groove 1806; the axes of the rolling bearing 1802 in the said caulking groove 1805 and the rolling bearing 1802 in the said mounting groove 1803 are perpendicular to each other. When mounting, the steel wires 922 connected with the two opposite connecting rods 3032 are wound on a pair of rolling bearings 1802 with the axes parallel to each other, for example, in terms of the position of fig. 8, the steel wires 922 of the two connecting rods 3032 at the left and right sides are wound on the rolling bearings 1802 in the embedded groove 1805, and the steel wires 922 of the two connecting rods 3032 at the front and rear sides are wound on the rolling bearings 1802 in the embedded groove 1803, so that the four steel wires 922 are respectively wound on the corresponding rolling bearings 1802 and then extend upwards to adjust the movement of the valve plate 303 by pulling or releasing the steel wires 922 outside the box body 3; of course, in order to make the operation simpler, the valve plates 303 move more synchronously or all the valve plates 303 need to move synchronously, four steel wires 922 can be tied together at one point after bypassing the pulley assembly 18 and then led out through another traction steel cable (not numbered in the figure) to realize integral pulling. In order to enable the connecting rod 3032 to slide upwards, namely the connecting rod 3032 can be more accurately limited when being retracted into the shaft lever 92, a horizontal limiting plate 923 can be fixed in the shaft lever 92 so as to block the height position of the end part of the connecting rod 3032 which obliquely moves upwards in the shaft lever 92, and the flexible control of the moving position of the valve plate 303 is realized.

In addition, in this embodiment, if it is not considered that when the inner cavity of the box body 3 is divided into two independent upper and lower chambers, and the chamber with the upper portion as the storage bin can stir the asphalt mixture, the valve plate 303 structure of the present invention is not adopted, and the valve plate 303 is directly manufactured into a simple rectangular plate-shaped structure (strip plate) and a connecting handle, and the annular discharge channel 301 is correspondingly designed into 4 simple insertion holes, and the insertion holes are in dynamic sealing insertion fit with the strip plate, that is, the function of the strip plate is similar to that of the arc-shaped sheet body 3031, and the function of the connecting plate is similar to that of the connecting rod, only when the valve plate 303 closes the discharge channel 301 at this time, the shaft 92 cannot realize stirring function, and the asphalt mixture in the box body 3 must be stirred after the valve plate 303 leaves the discharge channel 301, but the upper and lower chambers of the inner cavity of the box body 3 are already communicated, the unstirred mix has actually entered the lower bin and flowed out of the discharge pipe. However, this construction is simpler and is suitable for asphalt mixes which are prepared more immediately during operation, or for which a portion of the asphalt mix is discharged at the beginning of use and then the pavement is repaired when the stirred asphalt begins to be discharged.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
