However, since these nozzles are provided on the outer side of the side plate of the cutting box, when the cutting box is drilled down or the cutting box is opened by air injection or guniting, the sealing plate in the nozzle exceeds the outer surface of the side plate of the cutting box and is broken by the rail chain, so that the grout pipe or air pipe in the cutting box is easily clogged with soil, and the sealing plate cannot exert its intended function.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to the not enough that exists among the prior art, invented a protection type spout cutting case, this protection type spout cutting case, novel structure can prevent effectively that shrouding in the spout from being pulled bad by the rail chain to can make the thick liquid pipe and the trachea of cutting incasement can work unobstructed.
In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a protection type spout cutting box, contains curb plate 1, nozzle stub 2, mounting plate 3 and shrouding 4, it has the through-hole to open on the curb plate 1, the one end of nozzle stub 2 is connected with curb plate 1 and is sealed and with the through-hole intercommunication on the curb plate 1, there is mounting plate 3 in the nozzle stub 2, mounting plate 3's outer peripheral face is connected sealedly with the inner peripheral surface of nozzle stub 2, shrouding 4 is installed in mounting plate 3's the outside, the through-hole on shrouding 4's the inboard plane shutoff mounting plate 3, the outside plane of shrouding 4 is less than curb plate 1.
As a better embodiment, the through holes on the side plates 1 are circular holes, the short pipes 2 are circular short pipes, the installation bottom plate 3 is a circular bottom plate, the outer circumferential surface of the installation bottom plate 3 is connected and sealed with the inner circumferential surface of the short pipes 2, and the short pipes 2, the installation bottom plate 3 and the circular through holes on the side plates 1 are arranged coaxially.
As another preferred embodiment, the sealing plate 4 is a circular sealing plate, and the circular sealing plate 4 is coaxially arranged with the circular through holes on the short pipe 2, the mounting base plate 3 and the side plate 1.
As another preferred embodiment, the outer planar surface of the closing plate 4 is lower than the outer planar surface 12 of the side plate 1.
As another preferred embodiment, the outer plane of the closing plate 4 is lower than the inner plane 11 of the side plate 1.
As another preferred embodiment, the distance between the outer planar surface of the sealing plate 4 and the outer planar surface 12 of the side plate 1 is greater than the radius of the sealing plate 4.
Drawings
FIG. 1 is a schematic diagram of the nozzle position of a protective nozzle cutting box.
Fig. 2 is a schematic diagram of a nozzle structure of a protective nozzle cutting box.
Detailed Description
In the schematic diagram of the nozzle position of the protective nozzle cutting box shown in fig. 1, the nozzle is located on the oblique side surface of the cutting box, the nozzle can also be located on the straight side surface of the cutting box, or the nozzle is located on both the straight side surface and the oblique side surface of the cutting box.
In the nozzle structure diagram of a protective nozzle cutting box shown in fig. 2, the protective nozzle cutting box comprises a side plate 1, a short pipe 2, a mounting bottom plate 3 and a sealing plate 4, wherein a through hole is formed on the side plate 1, one end of the short pipe 2 is connected and sealed with the side plate 1 in a welding mode and communicated with the through hole on the side plate 1, the mounting bottom plate 3 is arranged in the short pipe 2, the outer peripheral surface of the mounting bottom plate 3 is connected and sealed with the inner peripheral surface of the short pipe 2 in a welding mode, the sealing plate 4 is fastened and mounted on the outer side of the mounting bottom plate 3 through a bolt, the through hole on the mounting bottom plate 3 is sealed by the inner side plane of the sealing plate 4, the outer side plane of the sealing plate 4 is lower than the side plate 1, the outer plane of the sealing plate 4 is lower than the outer plane 12 of the side plate 1, or the outer plane of the sealing plate 5 is lower than the inner plane 11 of the side plate 1, or the distance between the outer plane of the sealing plate 5 and the outer plane 12 of the side plate 1 is larger than the radius of the sealing plate 4. The through hole on the side plate 1 can be a circular hole, the short pipe 2 is a circular short pipe, the mounting base plate 3 is a circular base plate, and the short pipe 2, the mounting base plate 3 and the circular through hole on the side plate 1 are arranged coaxially; the sealing plate 4 can also be a circular sealing plate, and the circular sealing plate 4 is coaxially arranged with the circular through holes on the short pipe 2, the mounting base plate 3 and the side plate 1.
The protective nozzle cutting box also comprises a communicating pipe 5, the communicating pipe 5 can be connected and communicated with the through hole on the mounting bottom plate 3, or can be connected and communicated with the other end of the short pipe 2, and the technical effects are the same. In addition, the short pipe 2 and the mounting base plate 3 can be integrated into a whole and the welding process is omitted, but the technical effects of the short pipe 2 and the mounting base plate 3 are the same whether the short pipe and the mounting base plate are integrated into a whole or are connected into a whole through welding and sealing.
In practice, 2 or 4 nozzles can be arranged on one cutting box. E.g. 2 jets, are typically arranged on both symmetrical sides of the cutting box, e.g. a second jet 6 is also arranged in fig. 1; e.g. 4 jets, typically 2 each are arranged on the straight and the oblique side of the cutting box.
When media such as compressed air or cement slurry flow through the through hole on the mounting base plate 3 through the communicating pipe 5, the sealing plate 4 is opened; when air supply or slurry supply is stopped, the sealing plate 4 blocks the through hole on the mounting base plate 3. Since the closure plate 4 is also within the outer planar surface 12 of the side panels 1 in the open condition, the moving track chain is prevented from pulling the closure plate apart. Because shrouding 4 is in intact state all the time, can effectively prevent to make thick liquid pipe or trachea in the cutting box blockked up by earth because of the shrouding damages, ensure that equipment can normally be under construction.
