3 the connecting rod, and the connecting rod or the connecting sleeve is driven by the reciprocating component to reciprocate, thus realizing telescopic water supply, solving the problem that a reciprocating impact head of a reciprocating impact coal mining machine needs an internal spray to reduce dust and cool the impact head, meeting the practical need of reducing the abrasion of the impact head, and avoiding damage of the water source pipeline when the water supply pipeline impacted by the impact head in a reciprocating manner stretches and contracts along with the reciprocating impact head 2. The impact guide rod cavity is connected to the water passage, and the water source in the pipeline enters the impact guide rod cavity via the connecting sleeve and the connecting rod and arrives at the nozzle together with the water passage of the impact head, so that the advantages of connection and reciprocating motion of the impact guide rod and the impact head are sufficiently utilized; water required by the impact head is delivered to the impact head, so that components required for setting the internal spray system of the impact head and connected with the impact head are reduced, and easily damaged parts outside the box body are reduced; the connector and the connecting sleeve are arranged in the box body, so that impact damage of materials is avoided, and the structure is simple and skilful; the impact guide rod is formed as a thick water delivery pipeline, so that water has a good cooling effect on the impact guide rod, and the service life of the impact guide rod is prolonged; the connecting rod or the connecting sleeve is connected with the impact guide rod to reduce the installation size, and reciprocates along with the impact guide rod, so that the required installation space is small, the structure is compact and the installation position is flexible and adjustable.
3. The sealing element is arranged between the connecting rod and the connecting sleeve to avoid water leakage from the gap between the connecting rod and the connecting sleeve.
3. The sealing element is arranged between the connecting rod and the connecting sleeve to avoid water leakage from the gap between the connecting rod and the connecting sleeve.

5. The pressure meter is provided to ensure the stability of water pressure, and the booster is provided to avoid the fault that water is difficult to arrive at the nozzle due to insufficient water pressure.
6. The nozzle arranged on the impact tooth achieves a good cooling effect on the impact tooth and prolongs the service life of the impact tooth; and the nozzle is arranged on the brace, and the brace does not rotate outwards to deliver materials, so the nozzle is unlikely to be blocked and damaged relative to the nozzle of a drum mining machine.
7. The angle of the nozzle head is adjustable, so that the effect of the nozzle is improved and the nozzle is prevented from working idly.
8. The dust settling efficiency of the water source is improved and the working environment is purified by providing the atomizer; damage such as impact to the nozzle is avoided due to providing the nozzle protective cover; and because the brace does not rotate outwards to deliver materials, the nozzle protective cover may be formed to be larger, and the larger nozzle protective cover does not hinder discharging.
9. The brace is provided with a nozzle holder mounting pit, which effectively protects the nozzle holder from being damaged by impact.
10. The sealing element is arranged at the position where the nozzle head and the nozzle holder are mounted to reduce the loss of water and improve the water spray effect.
11. The trough is formed on the box body and the impact head, and the box body and the impact head form the pipeline, so that easy damage of external pipelines is reduced and the utilization rate of the box body and the impact head is improved.

13. The anti-damage adjustor is arranged at the joint of the connecting rod or the connecting sleeve and the box body, so as to prevent the reciprocating impact lateral force of the impact head from damaging the connecting rod and the connecting sleeve.
14. The connecting rod is arranged in the box body, oil mist splashes in the box body, and the splashing oil mist has a lubricating protection effect on the connecting rod.
15. The water passage of the internal and external spray mechanism does not pass through a power shaft, so that rusting damage of water leakage to power components and transmission components is avoided, and the water spray system is simple in structure, firm, reliable and long in service life relative to the water spray system of the drum mining machine.
16. The whole water spray system needs a few sealing leak-proof points and has low sealing difficulty, so that the manufacturing difficulty is greatly reduced; a plurality of small sealing elements may be arranged between the connecting rod and the connecting sleeve, so that the sealing effect is greatly improved on structural design, whereas the drum mining machine has many rotary sealing points, high rotary sealing difficulty, complex rotary sealing elements and high rotary sealing strength, so the rotary cutting resistance is improved; and the connecting rod and the connecting sleeve are sealed simply, the sealing points are few, and the sealing element is simple, so the sealing difficulty is low, the resistance of the sealing element is low and the power consumption is reduced.
17. Compared with the water passage system of the cutting part of the drum mining machine, the structure is extremely simple; when water leaks, the water passage is blocked or other problem occurs, the drum mining machine can be maintained only after large-sized components such as a cutting drum, a rotary disc and the like are detached, so the maintenance is complex, difficult and high in labor and time consumption; when the reciprocating water supply system is maintained, the cutting part does not need to be detached, and maintenance can be completed via a common maintenance window on the box body or directly implemented outside the impact power box; and the reciprocating telescopic water supply device of the impact mining machine has a few structural components, and is good in usability among the components, strong in universality among the components, easy to maintain and replace, safe, reliable and long in service life.
