What drill can drill diamond heads? ——Analysis of hot topics and equipment on the Internet in the past 10 days
Recently, the topic of "what equipment to use for diamond heads" has triggered widespread discussion in the field of construction machinery. The following is structured content compiled based on hot topics across the Internet in the past 10 days, covering device types, applicable scenarios and performance comparisons.
1. Analysis of popular drilling rig types and applicability
| Rig type | Applicable stone hardness | Typical application scenarios | Popular brands (search volume in the past 10 days) |
|---|---|---|---|
| Rotary drilling rig | Medium hard rock (such as limestone) | Building foundations, bridge pile foundations | Sany Heavy Industry, XCMG |
| Down the hole drilling rig | Hard rock (granite, basalt) | Mining, tunnel engineering | Atlas, Sunward Intelligence |
| Hydraulic rock drill | Extremely hard rock (quartzite) | Precision blasting holes and stone carvings | Sandvik, Caterpillar |
| Portable electric hammer | Soft rock (shale) | Home renovation, small projects | Bosch, Dongcheng |
2. Hot technical discussions in the past 10 days
1.Intelligent upgrade: Many manufacturers have launched drilling rigs equipped with AI rock recognition systems that can automatically adjust drilling speed based on geological data (such as the Sany Heavy Industry SY650H model).
2.Environmental protection needs: The search volume of electric hydraulic drilling rig increased by 120%, which is especially suitable for urban silent construction (refer to Sunward Intelligent SWDE120A).
3. The five major issues that users are most concerned about (data source: Zhihu/Baidu Index)
| Ranking | question | frequency of occurrence |
|---|---|---|
| 1 | What equipment is used for household diamond heads? | 3500+ |
| 2 | Cost estimate for drilling granite | 2800+ |
| 3 | Can small drilling rigs replace large equipment? | 1900+ |
| 4 | Drill bit material selection (diamond vs alloy) | 1600+ |
| 5 | Dust treatment solutions for rock drilling | 1200+ |
4. Suggestions on purchasing
1.Hardness matching: Igneous rocks such as basalt need to choose a down-the-hole drilling rig with an impact force >15kJ, while ordinary rotary drilling rigs can be used for sedimentary rocks.
2.Efficiency comparison: Taking a hole with a diameter of 50cm and a depth of 10 meters as an example, a hydraulic rock drill takes about 2 hours and a traditional impact drill takes 6-8 hours.
3.cost control: The comprehensive cost of granite drilling is about 80-120 yuan/meter (including equipment depreciation + labor), and the construction period requirements need to be comprehensively evaluated.
5. Industry trends
According to data from Huicong Machinery Network, sales of rock drilling rigs in Q1 2024 will increase by 23% year-on-year, with modular design (such as quick-change bit systems) becoming a mainstream selling point. The purchase volume of environmentally friendly water mist dust suppression equipment increased simultaneously by 45%.
The above content combines recent hot topics and actual engineering needs to provide reference for the selection of diamond head equipment. The specific plan needs to be further optimized based on geological reports and construction conditions.
