With its portable and efficient performance, the backpack drilling rig has been defined as an indispensable shallow sampling tool by users in the industry after many years of practice. The series of portable core dill machines have a variety of different power drilling rigs. Different power configurations can be better applied to shallow exploration sampling work in different formations and geological conditions. This series of backpack core drilling rigs are mainly suitable for areas with high mountains, inconvenient transportation, and a lack of water sources.

Backpack drilling rigs are also called portable diamond core drill rigs, backpack drill exploration rigs, and handheld core drilling rigs. The backpack core drill is a small sampling drilling machine widely used in plains, mountainous areas, and areas with inconvenient transportation and energy. This portable core drill has the advantages of a compact structure, small footprint, lightweight and convenient movement. The backpack core drill machine is suitable for railway, water conservancy, and other construction projects and geological sampling surveys, geological core drilling, small grouting holes, blasting holes, etc. in outdoor mountainous areas. Backpack drill bits such as diamond, composite sheet, and alloy can be selected according to different formations. If you are ready to buy a backpack drilling machine, please leave a message.
Features of Backpack Portable Core Drill
The small portable sample core rig is easy to operate and can replace traditional trenching, well exploration, and geophysical and geochemical anomaly verification. And can greatly reduce vegetation damage and protect the ecological environment. YG backpack core drilling rig is an indispensable technical means in shallow geological surveys such as regional geological mapping, geophysical and geochemical sampling, paleomagnetic sampling, and geological disaster prevention. Please feel free to contact us if you want to know more details about our backpack drilling equipment.
Choose the topography of the operation, and clarify the division of work of the main and deputy operators. And put the equipment in order. It is better to prepare a 1 square meter plastic sheet as bedding. Keep gasoline and engine oil away from flammable materials. Fill the pressure bottle or sprayer with water, and choose the appropriate drill bit or flushing fluid according to the stratum structure. Then tighten the drill bit to the drill tool. Finally, use the adapter to connect the drill tool with the drill bit and the machine head firmly.
2. Filling up fuel:
Before starting the engine, you must add enough oil to avoid damage to the engine. Use clean, fresh, unleaded gasoline with an octane number of not less than 85. Pour oil into the fuel tank. At the same time, check whether the oil connection between the carburetor and the fuel tank is normal. And then, press the pump oil cap a few times to let the fuel enter the cylinder. Please note that check the oil level before each use, the oil should be changed every 20 hours after the first use, and the oil needs to be filled with good oil. The oil should be changed every 50 hours afterward.
Turn on the switch to ignite and start the rig (pump oil → push the circuit switch (red button) up → adjust the air door → pull the hand strap to start the machine → open the air door immediately after the main engine starts to → adjust the water volume → drill in the correct posture.
4. Make the hole correctly:
Select the whole surface. Connect the water valve to the bucket to pressurize and pass water, adjust the water volume to the proper flow. And then, ignite the fire. The backpack drill rig is inclined to use the arch of the foot to step on the bottom of the drill pipe. And the foot is as far inward as possible to buckle to prevent slippage during the opening process. Do not open the hole too fast, first open a crescent, and gradually straighten the drill pipe quickly. Drill down vertically. Do not straighten the drill at once to avoid breaking off the drill bit. Requirements: The hole alignment & round, and the core is continuous.
5. Oblique angle operation:
The essentials of oblique hole drilling are similar to the first two, except that the drill pipe needs to be drilled according to the angle of inclination. It is necessary for one person to operate the drill and one person to hold the drill pipe by hand. Drilling requirements for rock drilling at full speed when the rig is turned on: hole alignment, hole circle, and continuous core.
1: Bedrock above 3 meters. Practice: Essentials: According to the principle of one steady, two listening, three watching, and four static, keeping the hole alignment and concentricity consistent, turning the drill pipe and drilling tool forward, choosing different drill bits for different formations, And drilling methods. Requirements: timely judge the situation in the well, and deal with the occurrence of plugging, stuck, dropped, buried, burned, and damaged drill bits.
2: Overburden deep hole exercise: Essentials: the same as the bedrock deep hole, but always pay attention to the casing rotation to prevent hole collapse, block dropping, and casing falling off. Requirements: Follow the pipe to drill into the core.
7. Overlay operation
1: Overlay drill, including 26PDC drilling and 36PDC drilling. Essentials: Light pressure at medium speed, lifting up and down, large water volume. The hole is close to the outer longitude of the drill pipe (the smaller the disturbance, the better).
2: Overburden core practice. Soil sample practice essentials: turn off the water valve and press lightly to drill slowly; core practice essentials: first run the casing into the bedrock, fix the casing, and run the 26 drilling tools to drill with the tube If the core is full or the core is broken, take the core in time.
Do not back-drill when tripping, and do not immediately shut down and stop drilling suddenly, but
trip at a uniform and slow speed. Because our drilling rig is 1,920 drills per minute, a sudden stop of drilling at such a high speed will cause sticking and drilling (drilling is generally between 800-2000 rpm). Gradually break away from the bottom of the hole and trip out safely. If the core is in the drill tool, remove the adapter and take out the core. If the core is not broken, put down the core remover, and cut the core with a hard protruding part. And then, take it out with a T-wrench.

9. Finishing work
1: Separate the drilling tool (or drill pipe) from the main engine and place them separately. The operator should put aside the main engine for a period of time, and then wipe it clean after cooling the machine body.
2: Remove the drill bit from the drill tool. When unloading the drill bit, use special pliers to clamp the steel body of the drill bit tightly. It is forbidden to jam the carcass, which is brittle and fragile.
3: Collect drilling data and make drilling records. Observe the use of drill bits, drill tools, drill pipes, and machines, and make records.
4: Clean the backpack drill machine, drill pipe, drill tool, etc. Put the core away.
