Abstract
The utility model discloses a spraying device of a cold regenerator, and relates to an engineering machine. A G-type single-screw pump is selected and used as the water pump; the pump is a displacement pump and has stable displacement; an electromagnetic flowmeter which can accurately measure the flow rate is additionally arranged in a water outlet pipeline; in addition, a nozzle part is controlled to be started by a cylinder, thus being convenient for operation. The main structure of the spraying device is as follows: a hydraulic motor is arranged on a rack and connected with the screw pump by a coupler; the screw pump is fixed on the rack by a bolt; a water inlet of the screw pump is connected with a water inlet bent pipe, a ball valve and a water inlet straight pipe by bolts; a water outlet of the screw pump is connected with a water outlet bent pipe and an electromagnetic flowmeter by bolts, and connected with a water box through a rubber pipe by a clamp; a water spraying pipe is welded on the water box; a copper sleeve is inlaid inside the water spraying pipe; and the cylinder is connected with the water spraying pipe by outer threads. The spraying device of the cold regenerator can accurately control the moisture content of asphalt material and roadbed and the proportion of emulsified asphalt, and has simple structure and reliable performance. The spraying device is mainly applied to construction of milling, mixing and on-site regeneration of the existing asphalt roadbeds.
Description
Technical field
The utility model relates to a kind of engineering machinery, especially the flusher of cold regenerative machine.
Background technology
For the maintenance and the transformation of old asphalt pavement, cold regenerative machine is widely used, and can mill old asphalt pavement and mix and add materials such as mulseal, water on the spot, and old road pavement recycling is used.This just need be in milling, mix and stir in the process, the ratio or the water content of mulseal in drop material, the roadbed is precisely controlled, to reach construction requirement.At present, the flusher of cold regenerative machine is mainly by the suction of motor or motor-driven centrifugal pump, and the electronic or manual modulation valve in is by the road adjusted opening angle, controls the size of flow, after a plurality of nozzle ejection that has valve is relatively simple for structure.But because centrifugal pump revolution discharge capacity instability, leakage rate was bigger when pressure was high, and this just causes flow rate of liquid shakiness in the pipeline, and is inaccurate to the flow-control of mulseal or water by control valve the time; In addition, can cause after the long-time use of the valve on the nozzle to be not closed completely, and operation inconvenience.
Summary of the invention
The purpose of this utility model provides a kind of novel cold regenerative machine flusher, with solve the prior art complex structure, flow-control is inaccurate, problems such as unstable properties.
The utility model mainly is made up of motor, water pump, pipeline, control valve, solves the technical scheme that its technical problem adopts to be: water pump has been selected model G single screw pump for use, and this pump is a displacement pump, and discharge capacity is stable; And in outlet pipeline, installed the electromagnetic flowmeter that accurately to measure flow additional; Nozzle segment is opened by cylinder control in addition, and is easy to operate.Its primary structure is: hydraulic motor is arranged on the frame, be connected with screw pump by shaft coupling, screw pump is fixed by bolts on the frame, its water inlet connects water inlet bend pipe, ball valve and water inlet straight tube with bolt, the screw pump delivery port connects Discharging bent-tube, electromagnetic flowmeter with bolt, uses clamp connection on the water box through sebific duct, and sparge pipe is welded on the water box, edge copper sheathing in the sparge pipe, cylinder is connected with the sparge pipe external screw thread.
The beneficial effects of the utility model are: by this flusher, can precisely control the water content of drop material, roadbed or the ratio of mulseal, and simple in structure, dependable performance.The flusher of this cold regenerative machine be mainly used in mill mix, in the construction of in-place regeneration old asphalt pavement.Because of in work progress, to the water content of drop material, roadbed or the relatively strictness of proportion requirement of mulseal,, can precisely control the ratio of its water content or mulseal by this flusher, and dependable performance.

The specific embodiment
In Fig. 1 and Fig. 2, hydraulic motor (10) is fixed by bolts on the frame, is connected with single-screw (single screw) pump (8) by shaft coupling (9), and screw pump is fixed by bolts on the frame, and its water inlet connects water inlet bend pipe (7), ball valve (6) and water inlet straight tube (5) with bolt; The screw pump delivery port connects Discharging bent-tube (4), electromagnetic flowmeter (3) with bolt, uses clamp connection on water box (11) through sebific duct (2);
In Fig. 3, sparge pipe (13) is welded on the water box (11), edge copper sheathing (14) in the sparge pipe, and cylinder (1) is connected with the sparge pipe external screw thread, and by the air inlet of motor air pump, cylinder awl bar shrinks control to be opened, and discharges through nozzle (12).
The flusher course of work of cold regenerative machine: hydraulic motor drives water pump by shaft coupling, from water inlet straight tube process ball valve, water inlet bend pipe suction (or mulseal), enter the water box through screw pump delivery port, Discharging bent-tube, electromagnetic flowmeter, sebific duct, open, discharge through nozzle by cylinder control.
Claims (3)
