Description
Technical field
The invention belongs to mining device technique field, be specifically related to a kind of nozzle come off too low with hydraulic pressure or cut off the water time can prevent current short circuit and water system from blocking flitting inner spraying nozzle mounting seat.
Background technology
Machine mining face is the main source of In Modern Mine dust, and coal-winning machine coal cutting produce that dust accounts for the total dust of work plane 80%." safety regulations in coal mine " specifies that coal-winning machine must install inside and outside atomization mechanism.At present, China's major part mining area coal cutter dust reduction mainly relies on the inside and outside spraying system of self.Coal miner spray dust falling system is the most critical device directly reducing fully-mechanized mining working dust.Inner spraying nozzle is generally arranged on the helical blade between coal mining machine roller pick, and its Main Function forms moisture film in pick Xia Chanchen district, covers dirt source, implement wet type cut, suppress the generation of dust.
From the actual service condition of coal-winning machine internal spraying, often because coming off of individual nozzles causes current short circuit, cause other nozzle supplies water pressure and the water yield to decline, thus cause spray nozzle clogging and affect the normal use of internal spraying.Meanwhile, when internal spraying system pressure of supply water is too low or cut off the water, the coal petrography chip that coal mining machine roller coal cutting produces can enter water system from Nozzle through nozzle base, and whole water system is blocked, and internal spraying system can not normally use.
Summary of the invention
The object of the invention is to the deficiency overcoming existing inner spraying nozzle mounting seat, provide a kind of structure simple, nozzle come off too low with hydraulic pressure or cut off the water time can prevent current short circuit and water system from blocking flitting inner spraying nozzle mounting seat.
The object of the invention is to realize by the following technical solutions: this flitting inner spraying nozzle mounting seat, be characterized in: comprising shell and to be placed in shell can the spool of left and right slippage, described shell is by the inlet opening for being connected with feed pipe, for the weep hole be connected with nozzle, left side wall, right side wall and pipe wall composition, described spool is by sealing cone, spring, sealing plectane, sealing ring and thimble composition, the port that the port that described inlet opening is connected with left side wall is connected with right side wall with described weep hole is all provided with sealing ring, described left side wall, right side wall is arranged in the left and right two-port of pipe wall respectively, spring is positioned at described pipe wall, its one end is bored with sealing and is connected, the other end is connected with sealing plectane, in the middle of described sealing plectane another side, thimble is installed, described spring is in compressive state, under described spring force effect, the cone mouth tip of described sealing cone is pushed into described inlet opening, described right side wall is close to by described sealing plectane.
In above-mentioned flitting inner spraying nozzle mounting seat, the cone bottom diameter of described sealing cone is greater than inlet opening and is less than the diameter of pipe wall, and the diameter of described sealing plectane is greater than weep hole and is less than the diameter of pipe wall, makes spool can left and right slippage in the enclosure.
In above-mentioned flitting inner spraying nozzle mounting seat, in described inlet opening, weep hole, be equipped with internal thread.
In above-mentioned flitting inner spraying nozzle mounting seat, described sealing ring is O RunddichtringO.
Technique effect of the present invention is: the nozzle mounting seat adopting said structure, when normally working, sealing cone is turned right and is pushed away by the hydraulic pressure that feed pipe provides, inlet opening is opened, current can enter in pipe wall, sealing plectane to be turned left by thimble and is pushed in pipe wall by nozzle, and weep hole is opened, and current can enter nozzle; When nozzle comes off, because thimble loses supporting surface, whole spool slippage to the right under the effect of hydraulic pressure, right side wall is close to by sealing plectane, and delivery port is closed, and prevents current short circuit, thus ensures the normal operation of other nozzle; When pressure of supply water is too low or cut off the water, sealing cone moves toward left side wall under spring force effect, is closed inlet opening, prevents external coal petrography chip from invading coal-winning machine water system.

Detailed description of the invention
As shown in Figure 1, the present invention includes shell and to be placed in shell can the spool of left and right slippage, shell is made up of inlet opening 1, weep hole 2, left side wall 3, right side wall 4 and pipe wall 5, spool by seal cone 6, spring 7, sealing plectane 8, thimble 9 and O RunddichtringO 10 form.The cone bottom diameter of sealing cone 6 is greater than inlet opening 1 and is less than the diameter of pipe wall 5, and the diameter of sealing plectane 8 is greater than weep hole 2 and is less than the diameter of pipe wall 5.The port that the port that inlet opening 1 is connected with left side wall 3 is connected with right side wall 4 with weep hole 2 is all provided with O RunddichtringO 10, left side wall 3, right side wall 4 is arranged in the left and right two-port of pipe wall 5 respectively, spring 7 is positioned at pipe wall 5, and be in compressive state, spring 7 one end is connected with sealing cone 6, the other end is connected with sealing plectane 8, sealing plectane 8 another side is provided with thimble 9, under the elastic force effect of spring 7, the cone mouth tip of sealing cone 6 is pushed into inlet opening 1, right side wall 4 is close to by sealing plectane 8, add the effect of O RunddichtringO 10, inlet opening 1 can be made, weep hole 2 is sealed up reliably.
Be equipped with internal thread 11 in inlet opening 1, weep hole 2, as shown in Figure 2, feed pipe is connected with inlet opening 1 by internal thread 11, and sealing cone 6 is turned right and pushed away by the hydraulic pressure that feed pipe provides, and inlet opening 1 is opened, and current can enter in pipe wall 5; Nozzle 12 is connected with weep hole 1 by internal thread 11, and to be turned left by sealing plectane 8 by thimble 9 and push in pipe wall 5, and weep hole 2 is opened, and current can enter nozzle 12.
As shown in Figure 3, when nozzle 12 comes off, because thimble 9 loses supporting surface, whole spool slippage to the right under the effect of hydraulic pressure, right side wall 4 is close to by sealing plectane 8, and closed by weep hole 2 under the effect of O RunddichtringO 10, prevent current short circuit, thus ensure the normal operation of other nozzle.
As shown in Figure 4, when pressure of supply water is too low or cut off the water, sealing cone 6 moves toward left side wall 3 by the spring 7 be under compressive state under the effect of elastic force, and by O RunddichtringO 10, inlet opening 1 is closed, stop external coal petrography chip to invade coal-winning machine water system, thus guarantee that its water system is not blocked.
