AI Technical Summary
Existing deep hole drilling rigs do not spray coolant precisely enough during the drilling process, resulting in wasted resources and an inability to effectively adjust the amount of coolant sprayed to meet the needs of different temperature zones.
Temperature memory metal is used to regulate the coolant output. The temperature memory metal expands and contracts in different temperature zones, causing the regulating block to move and adjusting the flow rate of the fluid delivery channel to precisely control the amount of coolant sprayed.
It enables automatic adjustment of coolant volume based on changes in drill bit temperature range, reducing resource waste and improving cooling efficiency.

Before deep-hole blasting, a deep-hole drilling machine is usually used to drill a deep hole at the mining working face, and related blasting tools are placed after the deep hole is drilled.
[0003] Through retrieval, a patent with the patent publication number CN119711926B discloses a pile drilling equipment for foundation construction. The pile drilling equipment can automatically adjust the amount of soil flowing out according to the looseness of the soil layer at the depth of the flow distribution plate, and compact the soil by extrusion of the tamping cylinder, thereby improving the tightness of the hole wall.
[0004] However, the above-mentioned invention has the following disadvantages. When drilling the working face, the drill bit contacts the soil or stones outside, which generates high temperature due to friction. Therefore, it is necessary to spray cooling liquid on the drill bit. The current cooling liquid spraying is spraying the whole spray head, and the temperature change occurs only when the drill bit contacts the soil or stones outside. If the cooling liquid is directly sprayed on the whole drill bit, the area with low temperature actually does not need to be sprayed with cooling liquid, which causes waste of cooling liquid.
