Embodiment Construction

[0029] The present invention is described in further detail below in conjunction with accompanying drawing:

[0030] Such as figure 1 , figure 2 As shown, a water jet road crushing device includes a support plate 3 and a nozzle 8, the nozzle 8 is installed on the lower end of the support plate 3 through a connecting rod device, the support plate 3 is fixedly installed on the lower end of the vehicle frame 1, and the connecting rod device can drive the nozzle 8 Rotate; the nozzle 8 is connected to the high-pressure water source through the through pipe 9;

[0031] The connecting rod device includes a swing rod 5 and a height-adjusting cylinder 4. One end of the swing rod 5 and one end of the height-adjusting cylinder 4 are both hinged to the lower end of the support plate 3. The other end of the swing rod 5 is hinged to a nozzle bracket 7, and the nozzle 8 is fixed to the nozzle On the bracket 7, the other end of the height-adjusting oil cylinder 4 is hinged on the swing rod...

Abstract

The invention discloses a water jet pavement crushing device which comprises a frame, connecting pins, a left supporting plate, a right supporting plate, a height adjusting oil cylinder, a swing rod,an angle oil cylinder, a nozzle support, a nozzle, a through pipe and a swing oil cylinder. The left and right supporting plates are hinged to the frame through the connecting pins; one of the heightadjusting oil cylinder and one end of the swing rod are hinged to the left and right supporting plates; the other end of the height adjusting oil cylinder is hinged to the swing rod, the other end ofthe swing rod is hinged to the nozzle support, the two ends of the angle oil cylinder are hinged to the swing rod and the nozzle support respectively, the nozzle and the through pipe are both installed on the nozzle support, and the two ends of the swing oil cylinder are hinged to the left supporting plate and the right supporting plate respectively. The height and the angle of a nozzle are adjusted through the height adjusting oil cylinder and the angle oil cylinder to be used for water jet crushing of a pavement, the angle of a jet device is adjusted through the swing oil cylinder to be usedfor cleaning and loading of the crushed pavement, the whole mechanism is simple and compact, the pavement crushing and cleaning requirements are met, and milling noise and dust pollution are reduced.

Description

technical field [0001] The invention relates to the field of road surface milling, in particular to a water jet road surface crushing device. Background technique [0002] At present, my country's highways have entered the "comprehensive maintenance era". With the passage of time and the increase of the total number of facilities, the demand for highway maintenance has shown a rapid growth trend. At present, road surface milling machine is one of the main equipment of asphalt pavement maintenance construction machinery, mainly used for excavation and renovation of asphalt concrete surface layers such as highways, urban roads, airports, freight yards, etc. The milling drum is its main working mechanism, and its application is relatively large. Extensive, but there are still some problems in the process of use. For example, a large number of tools are consumed during the milling process, dust and noise pollution are formed, so it is urgent to carry out research on new methods...
