[0040] The second sliding groove hole 31 is formed in the L-shaped bending plate 3, and two guide columns 6 for vertically passing through the drip irrigation belt are installed in the second sliding groove hole 31.

[0041] The guide column 6 comprises a fixed sleeve 62, a rotating sleeve 61 is rotatably arranged on the outer side of the fixed sleeve 62, one end of the fixed sleeve 62 protrudes out of the rotating sleeve 61 and a butterfly bolt 64 is threadedly connected at the end portion, a limiting protruding edge 63 is arranged on the fixed sleeve 62 protruding out of the rotating sleeve 61, the fixed sleeve 62 is slidingly arranged in the first sliding groove hole 231, the limiting protruding edge 63 and the butterfly bolt 64 are respectively located on the two sides of the sliding groove hole, and the fixed sleeve 62 is fastened and slid by rotating the butterfly bolt 64.

[0042] Two turning wheel mechanisms are arranged on the production line, the horizontally input drip irrigation belt is turned by 90 degrees into vertical output through the first turning wheel mechanism, and then the vertically input drip irrigation belt is turned by 90 degrees into horizontal output through the second turning wheel mechanism, so that the drip irrigation belt is turned by 180 degrees as a whole while the horizontal conveying direction is kept unchanged, the length of the production line is greatly shortened, and the layout requirements of different size workshops are met.

[0043] Preferably, the two guide columns 6 in the fourth sliding groove hole 42 and the two guide columns 6 in the second sliding groove hole 31 are located on the tangent line of the guide wheel 51. It ensures that the patch drip irrigation belt can be correctly cut into the outside of the guide wheel 51, reduces the extrusion force of the two guide columns 6 on the guide wheel 51 or the second sliding groove hole 31 on the patch drip irrigation belt, and ensures smooth conveying of the patch drip irrigation belt.

[0055] By turning the handle 82, the rotating shaft 81 and gear 8 are driven to rotate, which in turn drives the rack 71 and push rod 7 to move up and down, adjusting the height of the connecting block 22 and guide wheel 51. When the height is adjusted to a suitable level, the locking nut 83 is turned to make it contact and press against the outside of the fixing post 2, thus fixing the rotating shaft 81 in the current position.
