Description

A kind of sand hopper

Technical field:

The utility model relates to a kind of water-jet cutting machine member.

Background technology:

Existing water-jet cutting machine sand hopper, is formed by metal manufacture, determined by its structure, and one to carry out manufacturing cost high, two clean inconvenient.

Summary of the invention:

Goal of the invention of the present utility model is to provide a kind of simple in structure, low cost of manufacture, maintenance to be easy to sand hopper.

The utility model is to realize like this, comprise transparent cylindrical shell, be arranged on transparent cylindrical shell with sand derive the bottom of mouth, with the top cover for sand import and exhaust outlet, bottom middle part is connected with bolt, pass on the bolt of top cover and be connected with nut, bolt, nut are fixedly connected with bottom, transparent cylindrical shell, top cover.

When use, by adding sand for sand import toward sand storage tank, the effect of exhaust outlet be according to the sand in sand storage tank number regulate the air in sand storage tank, to ensure that the air pressure in sand storage tank communicates with atmosphere, with ensure that sand adds smoothly and importing sand valve in; While needing maintenance, clean sand storage tank, unclamp nut, just can easily the dismounting of sand storage tank also be cleaned easily.

For convenient fixing sand storage tank, bottom and top cover are provided with hook, on the gib head of hook, are provided with raised face.When fixing, on corresponding fixed pedestal, be provided with two slots, then hook injected in slot, make the raised face of gib head cross the bottom of slot, so that raised face plays the only effect of face, to prevent that sand storage tank is very freely shifted out in slot.

Compared with the prior art the utility model, has advantages of simple in structure, low cost of manufacture, maintenance easily and has preventing return water and adjustable suction.

Brief description of the drawings:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of sand valve.

Detailed description of the invention:

Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:

The utility model is to realize like this, the sand storage tank 20 that comprises sand valve 19 and be connected with sand valve 19, its special feature be sand storage tank 20 comprise transparent cylindrical shell 21, be arranged on transparent cylindrical shell 21 with sand derive the bottom 23 of mouth 22, with the top cover 26 for sand import 24 and exhaust outlet 25, bottom 23 middle parts are connected with bolt 27, pass on the bolt 27 of top cover 26 and be connected with nut 28, bolt 27, nut 28 are fixedly connected with bottom 23, transparent cylindrical shell 21, top cover 26, and the import of sand valve 19 is derived mouth 22 with the sand of bottom 23 and is connected.

Bottom 23 and top cover 26 are provided with hook 29, on the gib head 29a of hook 29, are provided with raised face 29b, so as hook 29 while injecting slot 34 set on corresponding fixed pedestal 33 after, be not easy to spin off.

Sand is derived mouth 22, bottom 23 use plastic monoblock manufactures (employing Shooting Technique) form, form for sand import 24, exhaust outlet 25, top cover 26 plastic monoblock manufactures (employing Shooting Technique), the hook 29 forming with metallic plate manufacture is with connecting plate 29c, bolt 27 lower ends are fixed with metal wishbone 30, metal wishbone 30 is fixed on a metallic plate 31, wherein the connecting plate 29c of a hook 29, metallic plate 31 are fixed on bottom 23 by screw 32, and the connecting plate 29c of another hook 29 is fixed on top cover 26 by screw 32.

Hook 29, connecting plate 29b are stamped to form by metallic plate entirety.

As shown in the figure, sand valve 19 comprises valve body 1, preventing return water mechanism 2, suction governor motion 3, valve body 1 comprises cavity 4, be arranged on middle part in cavity 4 with the leakage layer of sand plate 6 that leaks sand perforation 5, be arranged on layer of sand plate Lou 6 below derive perforation 7 with sand lead layer of sand plate 8, leak layer of sand plate 6, the spacing of leaking 5 of sand perforation is to make at the top of leading to form layer of sand plate 8, the diameter at the end that leaks the stable tapers heap 10 that sand perforation 5 hides to be less than to the diameter of leading layer of sand plate 8 and to determine from leaking sand 9 that sand perforation 5 flows out, sand is derived perforation 7 and is departed from the axis that leaks sand perforation 5, the edge that makes sand derive perforation 7 is positioned at from leaking sand perforation 5 and drops on outside the bottom edge of leading the taper heap 10 forming layer of sand plate 8, lead layer of sand plate 8 cavity 4 below and be connected with sand derivation passage 11, preventing return water mechanism 2 comprise under oblique and derive with sand the pipeline that passage 11 is connected in stop the pipe 13 of face 12 with taper, be arranged on taper and stop the ball float 14 on face 12, on duct wall on taper stops face 12, be provided with perforation 15, suction governor motion 3 comprise under oblique and derive with sand the tracheae 16 that passage 11 is connected, screw thread is screwed in the screw 17 in tracheae 16, on the sidewall of screwed tracheae 16, be provided with pore 18.
