Problems solved by technology

[0006] The above two kinds of laterally moving asphalt spraying devices adopt the method of laterally moving and spraying relative to the forward direction of the paver. Although the problem of incompatibility between the walking speed of the paver and the spraying speed is solved, there is no circulation pipe between the asphalt storage tank and the spray head. Road, after a horizontal spraying, the nozzle is turned off, and the next spraying is performed after moving back to the original position. Because the asphalt material has high temperature requirements, it is easy to accumulate and block the nozzle or pipe after cooling, thus affecting the spraying

Embodiment 1

[0034] Such as figure 1 , figure 2 and image 3 As shown, the asphalt spreading device of the present invention is fixedly installed on the frame of the asphalt paver through the installation frame 100, and is located at the rear of the paver body and before the distribution screw. For the convenience of description, the advancing direction of the paver is defined as the longitudinal direction, and the sleeve-type asphalt spreading device of this embodiment is arranged to extend horizontally.

[0035]The asphalt spreading device of this embodiment includes a fixed outer casing 1, a nozzle 2, a push hydraulic cylinder 3, a hollow piston rod 4, a piston 5, an inner sleeve 6, an asphalt input pipe 7, an asphalt return pipe 8, and a nozzle connecting frame 9. Wherein, the nozzle connecting frame 9 includes a connecting end block 9a, a vertical connecting pipe 9b, a three-way connecting block 9c and a horizontal connecting pipe 9d. The fixed outer casing 1 is installed on the m...

Embodiment 2

[0042] Such as Figure 5 and Image 6 As shown, the asphalt spreading device of the present embodiment comprises a sliding outer casing 201', a spray nozzle 2, a moving chain 203' ( Figure 7 ), fixed inner casing 206', asphalt input pipe 7, asphalt return pipe 8, fixed outer casing 201, pushing hydraulic cylinder 3, hollow piston rod 204, piston 205 and inner casing 206. Among them, the sliding outer casing 201', the nozzle 2, the moving chain 203', and the fixed inner casing 206' constitute the main asphalt spraying assembly, the fixed outer casing 201, the pushing hydraulic cylinder 3, the hollow piston rod 204, the piston 205 and the inner casing 206 The side asphalt spraying assembly is formed, the main asphalt spraying assembly is used to spray the road surface within the basic width of the paver, and the side asphalt spraying assembly is used to spray the road surface within the widened range beyond the basic width of the paver.

[0043] Such as Figure 5 As shown, t...

Embodiment 3

[0050] Such as Figure 8 As shown, the difference between this embodiment and Embodiment 2 is that the outer casing in the main asphalt spray assembly of this embodiment is fixed relative to the paver, and the inside of the fixed outer casing 301 is divided into oil inlet chamber a and oil inlet chamber a The upper oil return chamber b. There are two pairs of hollow piston rods 304 in this embodiment, which are arranged up and down. One pair of hollow piston rods 304 passes through the oil inlet chamber a, and the other pair of hollow piston rods 304 passes through the oil return chamber b. Each pair of hollow piston rods 304 is driven by the screw rod 303a controlled by the motor 303 to approach or move away from each other. The spray head 2 is installed below the end of the hollow piston rod 304 protruding from the fixed outer sleeve 301 through the spray head connecting frame. After the asphalt enters the oil inlet chamber a in the middle of the fixed outer sleeve 301 thr...

Abstract

Casing type asphalt spreading device and paver, the spreading device is installed on the body of the paver through the installation frame, located at the rear of the paver and before the distributing screw, which includes an outer casing, a hollow rod, a spray head, a drive The device, the outer sleeve and the hollow rod can move relatively laterally, and the driving device is used to control the relative movement between the outer sleeve and the hollow rod. The outer sleeve is provided with an oil inlet chamber and an oil return chamber, and the oil inlet chamber is connected to the asphalt storage through the asphalt input pipe. The tank is connected, connected with the nozzle through the asphalt inlet pipe, the oil return chamber is connected with the asphalt storage tank through the asphalt return pipe, and connected with the nozzle through the asphalt outlet pipe; the hollow rod is connected with the oil inlet chamber and the oil return chamber through the flow hole; the asphalt input pipe A quantitative pump and a gas / liquid control three-way valve are arranged at the air input end, and the gas / liquid control three-way valve is connected to the air compressor through the gas pipeline. The invention occupies little space and has simple and compact structure.

Description

technical field [0001] The invention belongs to the field of road construction machinery, and in particular relates to a laterally movable asphalt spreading device and an asphalt paver equipped with a movable asphalt spreading device. Background technique [0002] Asphalt pavement is a pavement structure in which a certain thickness of asphalt mixture is paved on a flexible base or a semi-rigid base. Compared with gravel pavement, this kind of pavement has greatly improved driving comfort, safety and strength stability. Compared with cement concrete pavement, asphalt pavement has a smooth surface without joints, small driving vibration, low noise, and fast construction. Short construction period, fast open traffic, easy maintenance, suitable for phased construction of pavement, is an important structural form of pavement in our country. [0003] In the past, when building asphalt-stabilized soil pavements or pavement bases, it was necessary to use a special asphalt distribu...
