Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the following will be combined with the drawings in the embodiments of the present invention, to the technical scheme in the embodiment of the utility model carry out it is clear,
It is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole implementation
Example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without creative efforts
The every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, Figure 2, shown in Fig. 7, a kind of water jet blade convenient for dredging sand-feeding tube, including pneumatic cylinder 1, pneumatic cylinder
1 upside is connected with taps pipe 2, and taps pipe is used to control the switch of high pressure water flow.The upside of taps pipe 2 is connected with
Extension bar 3, connecting rod 3 are internally provided with water stream channel.The upside of connecting rod 3 is connected with the first check valve 4, and the first check valve 4 is only
Allow water flow to spray from inside to outside from connecting rod 3, abrasive sand is sprayed into connecting rod 3 when back flush apparatus 9 works in order to prevent
It is interior.The upside of first check valve 4 is connected with mixing chamber 5, and mixing chamber 5 is used to mix high pressure water flow and abrasive sand.Mixing chamber 5
Side is equipped with sand-feeding tube 7, and sand-feeding tube 7 is made of metal material, preferably uses copper, and structure and hardness preferably and are not easy to get rusty.
The side of mixing chamber 5 is provided with sand inlet 8, and sand inlet 8 and sand-feeding tube 7 are tightly connected.
As shown in Fig. 4, Fig. 5, Fig. 6, several circular holes 71 are provided on the tube wall of sand-feeding tube 7, circular hole 71 is in contraposition arrangement, carefully
Metal bar can be smoothly inserted through, and be aligned in circular hole 71 after the blocking of sand-feeding tube 7 by hard thin metal bar insertion two,
The sand in the section herein of sand-feeding tube 7 can be disclosed, contraposition circular hole 71 in many places is provided on sand-feeding tube 7, therefore stifled in sand-feeding tube 7
It is easy to that sealing nut 72 is tightened to its internal sand discharge, the sand in sand-feeding tube 7 has become at this time after discharge after plug
It is more loose, then to cooperate back flush apparatus 9 to be used together effect more preferable.Circular hole 71 is internally provided with internal screw thread, seals spiral shell
External screw thread on mother 72 is adapted with internal screw thread, suitable for sealing sand-feeding tube 7.Circular hole 71 has been internally embedded sealing nut 72,
Seal washer 73 is installed, when sealing nut 72 is locked, the sealing effect of sand-feeding tube 7 is more preferable on sealing nut 72.Due into
7 lateral length of sandpipe is greater than radical length, therefore is much larger than its Radial resistant force along the lateral resistance of pipeline.It is designed by contraposition
Circular hole 71, being difficult to be discharged the even sand that can not be discharged originally can be easily from the radial direction going out inner product beach volleyball.
As shown in Figure 1, Figure 3, the upside of mixing chamber 5 is equipped with edge of a knife jet port 6, and the side of edge of a knife jet port 6 is connected with
Back flush pipe 91.Edge of a knife jet port 6 and back flush pipe 91 are tightly connected.It is single that the inside of back flush pipe 91 is equipped with second
To valve 93, the effect of second one-way valve 93 be when without using back flush apparatus 9, water flow can not from edge of a knife jet port 6 into
Enter in back flush pipe 91, to not influence normal high pressure waterjet.The side of the separate edge of a knife jet port 6 of second one-way valve 93
Force (forcing) pump 92 is installed, water stream S can be dredged the abrasive sand to deposit in sand-feeding tube 7 using hydraulic pressure in back flush
It is logical.The top open part of edge of a knife jet port 6 is equipped with sealing cover 10, only covers sealing cover 10 when back flush apparatus 9 works
Tightly, sealing cover 10 is disassembly status when cutting usually.
Taps pipe 2 is the switch of high pressure water flow on-off, is controlled by pneumatic cylinder 1.It is airproof in pneumatic cylinder 1
In the case of, pressure is generated by the spring inside pneumatic cylinder 1 and is in normally off.After pneumatic cylinder 1 is ventilated, pneumatic cylinder 1
Balancing out motions spring pressure, so that taps pipe 2 is opened.Connecting rod 3 connects taps pipe 2 and cutter head mixing chamber 5.
Edge of a knife jet port 6 is the place that high pressure water projects, and abrasive sand enters mixing chamber 5 by sand-feeding tube 7, passes through height in mixing chamber 5
Pressure water flow projects at a high speed after accelerating.
When sand-feeding tube 7 blocks, first sealing cover 10 is covered tightly, is dredged by back flush apparatus 9, if back flush
When device 9 can not solve, sealing nut 72 can be removed, be aligned in circular hole 71 with hard thin metal bar insertion two at this time, it will
Back flush apparatus 9 is recycled to be dredged after internal sand dredging.Without removing sand-feeding tube 7 in whole process, due into
7 lateral length of sandpipe is greater than radical length, therefore by the circular hole 71 of contraposition design, being difficult to be discharged originally can not be even discharged
Sand can be easily from the radial direction going out inner product beach volleyball.The device is easy to use and can dredge sand-feeding tube 7, solve into
The problem of sandpipe 7 blocks.
