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 pavement machinery, in particular to a paver screed with a locking function, including a screed body. A connecting rod is fixed to the top of the screed body, anoval plate with a groove formed in the upper surface is fixed to the top of the connecting rod and penetrates through the connecting plate to extend into a locking box, a concave hole is formed in theconnecting plate, the locking box is arranged in the concave hole, a round groove is formed in the middle of the locking box, an oval hole is formed in the bottom of the round groove, a partition plate is arranged at the top of the round groove, a limiting column is arranged on the partition plate, an elliptical plate of the device is convenient for connecting the screed to the connecting plate,the groove and the limiting column together prevent the elliptical plate from rotating, the locking box facilitates the locking of the elliptical plate, the round groove is convenient for the elliptical plate to rotate in the locking box to be inserted into an elliptical plate mounting box and then locked through a rotary mounting box, the locking mode of the elliptical plate and the mounting boxis not affected by vibration, so that the screed can be effectively prevented from falling off due to vibration, and faults and safety accidents which may occur in the actual working process are alsoavoided.
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...
