Furthermore, each support rod is vertically connected with the annular plate and the annular pipe respectively.

The utility model has the advantages that: will the utility model discloses on being used for installing the drill bit installation skeleton of rig, combine water pipe and tuber pipe, will press during wind and water injection ring canal, a plurality of shower nozzles on the rethread ring pipe spout water, realize spraying the effect, can effectively reduce the dust volume during the rig drilling, can also cool down to the drilling rod simultaneously.

[ description of the drawings ]

Fig. 1 is a schematic structural diagram of the present invention.

Wherein: 1. carrying out top thread; 2. a support bar; 3. a water jet; 4. a ring pipe; 5. pressing an air pipe; 6. a three-way joint; 7. and a water supply pipe.

[ detailed description ] embodiments

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The utility model discloses a rig drilling dust suppression device, as shown in fig. 1, including ring canal 4, it is a ring pipe, can make 360 ability dust suppression in step around drilling through this ring pipe, avoids local dust suppression effect poor.

A plurality of water spraying ports 3 are arranged on the same surface of the annular pipe at intervals, water in the annular pipe is sprayed out through the water spraying ports 3, and coal dust is driven to fall to the ground through water so as to reduce the coal dust generated during drilling. The distance between two adjacent water jet 3 equals, and at the during operation, because each water jet sprays water simultaneously, can produce reaction force etc. when spraying water, so can guarantee through this means that the reaction force etc. that receive on whole ring pipe are more even, avoid the ring pipe to take place the offset under the influence of reaction force when using. In addition, the distance between two adjacent water jet 3 is equal, also can guarantee the equilibrium of whole device, avoids because the unbalanced drill bit rocks when further influencing drilling of this device, increases the accuracy of drilling.

All install the shower nozzle on every water jet 3, the preferred copper shower nozzle that adopts, its durability is good, can also promote atomizing effect. Still have a water inlet on ring canal 4, a three way connection 6 is connected to the water inlet, uses three way connection 6 to expand into two imports with an import, and two imports insert pressure wind and water source simultaneously, have both increased water pressure and have reduced the water consumption, and two other interfaces of three way connection 6 are connected to wind regime and water source through compressed air pipe 5 and delivery pipe 7 respectively promptly. Can make through pressure tuber pipe 5 add the pressure wind in step when adding water for the ring tube, increase water pressure on the one hand, on the other hand can save the water yield.

The utility model discloses still include a lantern ring, the skeleton phase-match that is used for installing the drill bit on the shape of lantern ring and the rig for the cover is established and is used for installing the skeleton outside of drill bit on the rig. Since most drill rigs have a cylindrical skeleton, the preferred collar is an annular plate that is nested over the outer surface of the cylindrical skeleton. Seted up a plurality of screw hole on the cyclic annular board, all installed jackscrew 1 on every screw hole, can realize through jackscrew 1 the utility model discloses fixed between dust suppression device and the rig installs on the rig its is fixed.

The ring pipe 4 is connected with the lantern ring through a plurality of supporting rods 2, and the distance between two adjacent supporting rods 2 is equal, so that the balance of the whole device is guaranteed. Each support bar 2 is vertically connected to the annular plate and the collar 4, respectively, so that it is possible to connect and use a minimum of material, and it is preferable that the support bars 2 be made of a light material to reduce the weight of the entire apparatus.

In order to increase the equilibrium of whole device, avoid because this device focus is unstable and then the drill bit rocks when influencing drilling, reduce the accuracy of drilling, ring canal 4 and lantern ring 3 centre of a circle are guaranteed that the focus of whole device is located ring canal 4 and the centre of a circle department of sleeve pipe 3, increase the stability of whole device.

The utility model discloses simple structure, convenient to use, the practicality is strong, has reduced "occupational disease harm, coal dust accident", has improved work efficiency, ensures that safe construction and worker are healthy.
