The number of secondary arm segments 22 may vary depending on the product model, and may be, for example, one, two or more segments. For convenience of explanation of the embodiment of the present invention, the following description will be made with an optimized scheme in which the number of the secondary arm segments 22 is two, and as shown in fig. 1, the two secondary arm segments 22 are named a first secondary arm segment and a second secondary arm segment, respectively, from left to right. The length of the first secondary arm segment 21 is L4, the length of the first secondary arm segment is L5, and the length of the second secondary arm segment is L6.

The balance arm and the material distribution arm can respectively rotate in the horizontal plane relative to the tower body 10 through the second rotating assembly 50, so that the whole material distribution arm 20 can be driven to rotate and distribute materials relative to the tower body 10 by taking L4+ L5+ L6 as the radius; the first-section arm section 21 and the first-section arm section as well as the first-section arm section and the second-section arm section are connected by the first rotation assembly 90, so that the first rotation assembly 90 between the first-section arm section 21 and the first-section arm section simultaneously drives the tail ends of the first-section arm section and the second-section arm section relative to the first-section arm section 21 to distribute materials in a corresponding horizontal plane by taking L5+ L6 as a radius while the whole distribution arm rotates, and the first rotation assembly 90 between the first-section arm section and the second-section arm section drives the tail end of the second-section arm section relative to the first-section arm section to rotate in a corresponding horizontal plane by taking L6 as a radius, so that the distribution requirements of different ranges in the horizontal plane can be met. As shown in fig. 4, the maximum radius of the entire cloth arm is R2 ═ L4+ L5+ L6, so that during the cloth process, the blank area of the cloth is an area circle with a radius of L4-L5-L6. In addition, the invention can effectively improve the distribution radius of the tower type horizontal amplitude-changing material distributor by arranging the balance weight 31 at the left end of the balance arm 30 to balance part of the bending moment of the material distribution arm 20. Because the tower-type distributing machine is horizontally variable in amplitude, the prefabrication of large-area concrete components in a factory building is effectively solved, the construction efficiency is high, and the construction is safe and reliable.
