Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tunneling construction equipment, and in particular to an anti-blocking nozzle and a tunneling equipment. Background Art
[0002] A roadheader is a combined unit that can realize cutting, loading and transportation, self-propelling and spray dust removal. When the cutting head of the roadheader cuts, the dust is relatively large. At present, the spray dust reduction method sprays fine and dense water mist particles from the nozzle, and the dust reduction effect is good. Due to the poor working environment of the roadheader, when the nozzle is not in use, since the nozzle is in direct contact with dust and particles, the dust and particles are likely to enter the inside of the nozzle, resulting in nozzle blockage, and manual cleaning and maintenance are required frequently, which increases the manual labor cost and reduces the construction efficiency. Content of the Utility Model
[0003] In view of this, the purpose of this application is to provide an anti-blocking nozzle and a tunneling equipment to solve the problem that the nozzles on the existing roadheader are easily blocked by dust and particles and require manual cleaning and maintenance.
[0004] The first aspect of the utility model provides an anti-blocking nozzle, wherein the anti-blocking nozzle comprises:
[0005] A housing, inside which a liquid supply channel is formed, and both ends of the liquid supply channel are a water inlet and a water outlet;
[0006] A limiting member, arranged on the water inlet side inside the housing;
[0007] A sliding member, arranged on the water outlet side inside the housing, and a first through hole is formed in the sliding member to form part of the liquid supply channel;
[0008] An elastic member, arranged between the housing and the sliding member;
[0009] The pressure of the liquid entering through the water inlet can drive the sliding member to move away from the limiting member and squeeze the elastic member, so that the limiting member and the sliding member are separated to open the connection of the liquid supply channel; the elastic member resets to push the sliding member to move towards the direction close to the limiting member, so that the limiting member abuts against the first through hole to close the liquid supply channel.
[0010] Preferably, a protruding limiting part is formed at one end of the limiting member facing the sliding member, and at least part of the limiting part can extend into the first through hole.
[0011] Preferably, the circumferential side wall of the limiting part is inclined, so that the radial dimension of the side of the limiting part facing the first through hole is reduced.
[0012] Preferably, the limiting member is slidably connected to the housing, and the opening pressure of the liquid supply channel is adjusted by adjusting the position of the limiting member in the housing.
[0013] Preferably, the limiting member is threadedly connected to the housing.
[0014] Preferably, a second through hole is formed in the limiting member to form a part of the liquid supply channel.
[0015] Preferably, a limiting boss is formed on the inner wall of the housing, and the elastic member is clamped between the sliding member and the limiting boss.
[0016] Preferably, the anti-clogging nozzle further includes:
[0017] A sealing member, which is clamped between the inner wall of the housing and the outer wall of the sliding member.
[0018] Preferably, a groove is formed on the inner wall of the housing, and the sealing member is installed in the groove.
[0019] In a second aspect of the present invention, a tunneling device is provided, including the anti-clogging nozzle according to any one of the above technical solutions.
[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0021] The anti-clogging nozzle of the present invention has a simple structure and ingenious design. The pressure of the liquid entering through the water inlet can drive the sliding member to move away from the limiting member and compress the elastic member, so that the limiting member and the sliding member are separated. In this way, when dust suppression and temperature reduction are required, the liquid supply channel is automatically opened with the input of water pressure; when there is no liquid entering the water inlet or the pressure of the liquid is not enough to compress the elastic member, the elastic member resets to push the sliding member to move towards the limiting member, so that the limiting member abuts against the first through hole, thus closing the liquid supply channel. Therefore, when the nozzle is not in use, it can be in a closed state to prevent external dust and particles from entering the nozzle and clogging the nozzle, reducing the manual burden, enabling the tunneling device to quickly enter the construction state, and improving the work efficiency.

[0036] According to a first aspect of the present utility model, a clog - proof nozzle is provided, which includes a housing 10, a limiting member 20, a sliding member 30, and an elastic member 40.
[0037] Hereinafter, the specific structures of the above - mentioned components of the clog - proof nozzle according to this embodiment will be described.
[0038] In this embodiment, as Figure 1 shown, the housing 10 is formed into an annular cylindrical structure. A liquid supply channel 100 is formed inside the housing 10. The two ends of the liquid supply channel 100 are an inlet 101 and an outlet 102 respectively. Liquid enters the liquid supply channel 100 through the inlet 101 and is discharged from the outlet 102.
[0039] Optionally, the inlet 101 and the outlet 102 are provided at the two ends in the axial direction of the housing 10.
[0040] In this embodiment, as Figure 1 and Figure 2 shown, the limiting member 20, the sliding member 30, and the elastic member 40 are all provided inside the housing 10. Specifically, the limiting member 20 is provided on the side of the inlet 101 inside the housing 10, while the sliding member 30 is provided on the side of the outlet 102 inside the housing 10. Thus, along the flowing direction of the liquid in the liquid supply channel 100, the sliding member 30 is provided downstream of the limiting member 20. It should be noted that Figure 2 the dashed arrow in
[0041] Further, the slider 30 is capable of sliding relative to the housing 10. A first through hole 31 is formed in the slider 30 to form a partial liquid supply channel 100, so that the liquid entering from the water inlet 101 can enter the first through hole 31 and then spray outwards. The water outlet 102 can be arranged at one end of the first through hole 31 away from the limiting member 20.
[0042] The elastic member 40 is arranged between the housing 10 and the slider 30. The elastic member 40 can be a spring. Specifically, the elastic member 40 is arranged on the side of the slider 30 facing away from the limiting member 20. Such an arrangement enables the pressure of the liquid entering through the water inlet 101 to drive the slider 30 to move in a direction away from the limiting member 20 and compress the elastic member 40, so that the limiting member 20 and the slider 30 are separated to open the connection of the liquid supply channel 100, thereby realizing the automatic opening of the liquid supply channel 100 with the input of water pressure when dust removal and cooling are required. That is, when the liquid with a certain pressure enters the liquid supply channel 100 from the water inlet 101, the pressure of the liquid acts on the elastic member 40, causing the slider 30 to slide in a direction close to the elastic member 40. The elastic member 40 is compressed and one end of the first through hole 31 facing the limiting member 20 is unobstructed, so that the water inlet 101 and the water outlet 102 are in a connected state, thus realizing the spray.
[0043] When the spray is not needed, just stop supplying liquid to the anti-blocking water spray. When no liquid enters the water inlet 101 or the pressure of the liquid at this time is not sufficient to compress the elastic member 40, the compressed elastic member 40 resets to push the slider 30 to move in a direction close to the limiting member 20, so that the limiting member 20 abuts against the first through hole 31 to close the liquid supply channel 100, thereby enabling the nozzle to be in a closed state when not in use, preventing external dust and particles from entering the nozzle interior and blocking the nozzle, eliminating the need for manual cleaning and reducing the manual burden.
[0044] Further, in this embodiment, as Figure 1 shown, a protruding limiting portion 21 is formed at one end of the limiting member 20 facing the slider 30, and at least part of the limiting portion 21 can extend into the first through hole 31, so as to effectively block the first through hole 31 when the nozzle is not in use and prevent tiny dust and particles from entering.
[0045] Preferably, the circumferential side wall of the limiting portion 21 is inclined, so that the radial dimension of the side of the limiting portion 21 facing the first through hole 31 is reduced, so that the entire circumferential side wall of the limiting portion 21 can abut against one end of the first through hole 31 facing the limiting member 20 to effectively block the first through hole 31. The limiting portion 21 can be formed into a conical block structure or a frustum-shaped block structure.
[0046] In a preferred embodiment, the limiting member 20 is slidably connected to the housing 10. Thus, by adjusting the position of the limiting member 20 within the housing 10, the opening pressure of the liquid supply channel 100 can be adjusted. When the limiting member 20 is adjusted in the direction close to the sliding member 30, the opening pressure of the liquid supply channel 100 increases. When the limiting member 20 is adjusted in the direction away from the sliding member 30, the opening pressure of the liquid supply channel 100 decreases.
[0047] Preferably, the limiting member 20 is threadedly connected to the housing 10. Specifically, internal threads are provided on the inner wall of the housing 10, and external threads are provided on the outer wall of the limiting member 20. Thus, by adjusting the relative rotation of the limiting member 20 and the housing 10, the position of the limiting member 20 relative to the housing 10 can be changed, thereby facilitating the adjustment of the opening pressure of the liquid supply channel 100.
[0048] Preferably, as Figure 1 and Figure 2 shown, a second through hole 22 is formed in the limiting member 20 to form part of the liquid supply channel 100. By controlling whether the first through hole 31 and the second through hole 22 are communicated, the opening or closing of the liquid supply channel 100 can be controlled. One or more second through holes 22 can be provided. When multiple second through holes 22 are provided, the multiple second through holes 22 can be arranged at intervals around the axis of the limiting member 20.
[0049] In this embodiment, preferably, the axes of the housing 10, the limiting member 20, the sliding member 30, and the elastic member 40 are collinear.
[0050] In addition, in this embodiment, as Figure 1 and shown, a limiting boss 11 is formed on the inner wall of the housing 10. The limiting boss 11 is preferably an annular structure. The elastic member 40 is clamped between the sliding member 30 and the limiting boss 11, and the elastic member 40 abuts against the limiting boss 11 and the sliding member 30 respectively. Thus, the limiting boss 11 restricts the displacement of the elastic member 40 on the side away from the sliding member 30.
[0051] In this embodiment, as Figure 1 shown, the anti-clogging nozzle further includes a sealing member 50. The sealing member 50 can be an annular sealing ring. The sealing member 50 is clamped between the inner wall of the housing 10 and the outer wall of the sliding member 30 to prevent liquid leakage.
[0052] Preferably, as Figure 1 shown, a groove 12 is formed on the inner wall of the housing 10. The sealing member 50 is installed in the groove 12, thus preventing the sealing member 50 from moving around when the sliding member 30 slides. The shape of the groove 12 is adapted to the shape of the sealing member 50. For example, when the sealing member 50 is an annular structure, the groove 12 correspondingly forms an annular groove structure.
[0053] According to the anti-blocking nozzle of the present utility model, the structure is simple and the design is ingenious. The pressure of the liquid entering through the water inlet can drive the sliding member to move away from the limiting member and compress the elastic member, so that the limiting member and the sliding member are separated. In this way, when dust suppression and cooling are required, the liquid supply channel is automatically opened with the input of water pressure; when no liquid enters the water inlet or the pressure of the liquid is not enough to compress the elastic member, the elastic member resets to push the sliding member to move towards the direction close to the limiting member, so that the limiting member abuts against the first through hole, thus closing the liquid supply channel. Therefore, when the nozzle is not in use, it can be in a closed state to prevent external dust and particles from entering the nozzle and blocking it, reducing the manual burden.
[0054] The second aspect of the present utility model provides a tunneling device, including the anti-blocking nozzle described above. The tunneling device can be a continuous miner. The anti-blocking nozzle can keep the liquid supply channel closed when not in use, thus avoiding dust and particles from entering the nozzle and causing blockage, reducing the manual burden, enabling the tunneling device to quickly enter the construction state and improving work efficiency.
[0055] Finally, it should be noted that the above embodiments are only specific embodiments of the present application, used to illustrate the technical solutions of the present application, rather than limiting them. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that any person skilled in the art within the technical scope disclosed by the present application can still modify the technical solutions described in the foregoing embodiments or easily conceive of changes, or perform equivalent replacements for some of the technical features; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
