Abstract
The utility model relates to a pressurized spraying dust collector used for a tunneling machine in a coal mine roadway; the existing spraying dust collector uses a water source, has long delivery distance and high pressure drop, and can not meet requirements. The pressurized spraying dust collector provided by the utility model consists of a hydraulic motor, a cam, a piston rod, a spring, a piston, a shell, a conical nozzle and a water inlet pipe, and is characterized in that: the hydraulic motor is connected with the shell, and the conical nozzle is connected with the front end of the shell. When the hydraulic motor drives the piston rod to do reciprocating motion in the shell through the cam, pressure water entering a piston cavity from the water inlet pipe is continuously pressurized, and when the water passes through the conical nozzle, a flow area is gradually reduced, the water pressure is increased again. Compared with the prior art, the pressurized spraying dust collector has the beneficial effects of high water pressure, good atomization effect and long jetting range.
Description
Technical field, the utility model relate to the supercharging spraying firing dust device that uses on a kind of coal mine roadway development machine.
Background technology: under coal mine, in the tunnelling machine operation, can produce a large amount of coal dusts.Its employed water source of spraying firing dust device, because fed distance is long, pressure drop is big, the dirt water insufficient pressure that causes going out can not be satisfied the demand.
Summary of the invention: the utility model provides a kind of supercharging spraying firing dust device.It is by hydraulic motor, cam, and piston rod, spring, piston, housing, conical nozzle, water inlet pipe is formed, and it is characterized in that hydraulic motor is connected with housing, and conical nozzle is connected with the housing front end.Keep in touch with cam under spring action all the time the piston rod left side, and the piston rod right-hand member is connected with piston.When hydraulic motor drove the cam rotation, the piston rod driven plunger was reciprocating in the housing plunger shaft.The water that is got in the plunger shaft by water inlet pipe constantly is pressurized, and the reason water inlet pipe gets into the existing certain pressure of water of plunger shaft again, and after two pressure superposition, through conical nozzle the time, because of circulation area diminishes gradually, the pressure of water is strengthened again.During use, water inlet pipe is connected with the rubber water pipe.The hydraulic motor liquid inlet and outlet is connected with the tunnelling machine hydraulic system with fluid pressure line, and is controlled by the valve group.
The utility model positive effect compared with prior art is: hydraulic pressure is big, and atomizing effect is good, far firing range.
Description of drawings: accompanying drawing is the utility model structural representation.
The specific embodiment: shown in accompanying drawing, piston (3) is packed in the plunger shaft (13) of housing (2).Spring (6) is enclosed within on the piston rod (5), and piston rod (5) passes pilot hole (4) and is connected with piston (3).Cam (7) is connected with the output shaft (8) of hydraulic motor (9), and the left end of piston rod (5) keeps CONTACT WITH FRICTION with cam (7) under the effect of spring (6).Hydraulic motor (9) is connected with housing (2).Conical nozzle (1) is connected with housing (2) front end.Liquid inlet joint (10), fluid joint (11) is connected with hydraulic motor (9).
Claims (1)
1. supercharging spraying firing dust device, it is made up of hydraulic motor, cam, piston rod, spring, piston, housing, conical nozzle, water inlet pipe, it is characterized in that, and hydraulic motor is connected with housing, and conical nozzle is connected with the housing front end.
