Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing.

[0017] Such as figure 1 with figure 2 As shown, an automatic folding spraying rod of the present invention includes a main spraying rod 1 and spraying poles 12 on both sides. The main spraying rod 1 is provided with a spraying cylinder 2 and a lifting device 3. The two ends of the main spraying rod 1 are connected to the motor bracket 4 and Rotary joint 10, motor 5 is assembled on motor bracket 4, motor output shaft 51 is connected with input flange 8 through coupling 7; input flange 8 is connected with spraying pole 12 through connecting pipe 11; when working, the torque of motor 5 passes through The coupling 7 is transmitted to the input flange 8, and then to the swivel joint 10, so that the connecting pipe 11 drives the spraying pole 12 to fold or unfold. The hydraulic system can set the overflow pressure, such as reaching the position or encountering obstacles to rea...

Abstract

The invention discloses an automatically folding spraying rod. The automatically folding spraying rod comprises a main spraying rod and spraying radius rods on the two sides of the main spraying rod, wherein motor supports and rotule are arranged on the two ends of the main spraying rod, motors are assembled on the motor supports, and motor output shafts are connected to input flanges through couplings; the input flanges are connected to the spraying radius rods through connecting pipes; torques of the motors are transmitted to the input flanges through the couplings and further to the rotule so as to make the connecting pipes drive the spraying radius rods to fold or unfold. The automatically folded spraying rod changes the method that workers have to get under a chassis of a synchronous surface dressing machine to work, achieves automatic control through a button over the spraying rod which is difficult and dangerous to operate and needs to be unfolded and folded through manual work, thus improving comfort of operation and reducing danger in work under the chassis. Through the coordination between electric and hydraulic pressure, multiple functions such as automatic folding and unfolding, location and stop of the spraying rod are achieved.

Description

technical field [0001] The invention relates to an asphalt spraying device for road surface maintenance equipment, in particular to an automatic folding spray bar. Background technique [0002] Folding spraying booms are widely used in asphalt spraying devices of asphalt spraying vehicles and synchronous gravel sealing vehicles, and are generally folded and unfolded manually. For example: the working device of the synchronous crushed stone sealing vehicle includes a stone spreader and an asphalt spray bar. The stone spreader is installed at the rear of the car, and the asphalt spray bar is installed under the chassis. When the synchronous gravel sealing vehicle starts construction or finishes construction, it is necessary to manually drill under the chassis to fold and unfold the spray rod, which is inconvenient to operate and labor-intensive, and there are safety risks in working under the chassis. Contents of the invention [0003] Aiming at the above-mentioned problems...
