Shantui Co., Ltd. (000680) has newly obtained a utility model patent authorization. The patent name is "A screed for a paver", the patent application number is CN202422335047.5, and the authorization date is September 26, 2025.
Patent Abstract: This utility model relates to a screed for a paver, belonging to the field of
paving machine parts. Its technical solution comprises a base-screed device, with telescopic-screed devices slidingly mounted on either side of the base-screed device. A telescopic mechanism is disposed between the base-screed device and the telescopic-screed device. The base-screed device is provided with a connecting frame, which is provided with a first guide hole. The telescopic mechanism comprises a first side end plate, a second side end plate, and two sliding columns disposed between the two side end plates. Each layer of sliding columns has at least two sliding columns. The upper sliding column slides within the first guide hole, while the lower sliding column is slidably connected to the telescopic-screed device. During the first stage of telescopic extension, the two sliding columns move together. During the second stage of telescopic extension, the two sliding columns remain stationary. The telescopic-screed device moves along the length of the sliding column to complete the second stage of telescopic extension. This avoids the problem of using two independent telescopic mechanisms on one side, which results in weak torsional deformation resistance and difficulty in meeting the requirements of heavy-load construction.
