Problems solved by technology
[0003] Because the paving process is often accompanied by vibrations, and most of the current screeds and pavers are connected by bolts, this connection is easily affected by vibrations, because vibrations will change the pre-tightening force of the bolted connections, As a result, the nuts become loose, which in turn causes the screed to fall off, which will affect the paving efficiency in the actual work process and may cause safety accidents

The invention relates to the field of road machinery, in particular to a paver screed with a locking function, comprising a screed body, a connecting rod fixed on the top of the screed body, and an elliptical plate with a groove on the upper surface fixed on the top of the connecting rod , the elliptical plate passes through the connecting plate and extends into the locking box. There is a concave hole on the connecting plate, and a locking box is arranged in the concave hole. A partition is arranged on the top of the tank, and a restricting column is arranged on the partition. The elliptical plate of this device is convenient to connect the screed to the connecting plate, the groove and the restricting column together prevent the elliptical plate from rotating, the locking box facilitates locking the elliptical plate, and the round groove facilitates the rotation of the elliptical plate in the locking box. Insert the elliptical plate into the mounting box Finally, it is locked by rotating the installation box. The locking method of the elliptical plate and the installation box will not be affected by the vibration, so that it can effectively avoid the vibration that causes the screed to fall off, and also avoids possible problems in the actual work process. faults and safety incidents.
Description
technical field [0001] The invention relates to the field of road machinery, in particular to a paver screed with a locking function. Background technique [0002] As the core working device of the asphalt paver, the screed directly determines the paving quality and performance of the machine. At present, the asphalt paver screeds at home and abroad all adopt the rectangular box structure welded by steel plates. Paver is a machine that evenly spreads asphalt mixture on the road base, and performs preliminary vibration and leveling. The vibration mechanism uses a screed and a vibrator installed in front of the screed, or a vibrating screed, or Both the vibrator and the vibrating screed are used at the same time to improve the vibration effect. The screed device is composed of a screed, a traction arm, a thickness regulator, a road crown regulator and a heater. The vibration screed device is equipped with a vibrator on the screed, which can play the role of vibration compact...
