Description

Technical Field

[0001] This utility model relates to the field of drilling, and in particular to a hand-held ground drilling device. Background Technology

[0002] A ground drilling device is a piece of equipment used for ground drilling. It can quickly and accurately drill holes in the ground and is widely used in geological exploration, mineral resource exploration, construction, environmental surveys, soil sampling, and underground pipeline installation.

[0003] Existing hand-held drilling devices require operators to hold the handle and rotate the drill rod, which then drills into the ground to form a hole. However, on hard ground or when drilling multiple times, the operator expends a lot of energy, requiring intermittent rest, which affects drilling efficiency. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing hand-held drilling devices require operators to hold the handle and rotate the drill rod before drilling into the ground to form a hole. However, on hard ground or when drilling multiple times, the operator's physical strength is greatly consumed, leading to the need for intermittent rest, which in turn affects drilling efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a hand-held ground drilling device, including an engine, a connecting pipe at the output end of the engine, a round rod on one side of the connecting pipe, a square tube on one side of the round rod, a gear on one side of the round rod, a locking block at one end of the round rod, a drilling pipe on one side of the locking block, an auger on one side of the drilling rod, and mounting components on both sides of the square tube, wherein the mounting components are used to install the engine and the square tube.

[0006] The aforementioned components achieve the following effect: When drilling in the ground, the operator holds the drilling device by gripping the handle on the outside of the engine, then starts the engine. The engine output, through a connecting pipe, drives the round rod to rotate inside the square tube. The round rod then drives the gear fixed inside the square tube to rotate, which in turn drives the locking block fixed on one side of the round rod to rotate. The drilling rod, which is engaged inside the locking block, drives the auger fixed on one side to rotate on the ground. Drilling in the ground is then carried out. When the square tube needs to be replaced, the installation assembly is used to disassemble and install the engine and the square tube.

[0007] Preferably, the mounting assembly includes several bolts, nuts, a fixing plate, a first through hole and a second through hole on the fixing plate, and a third through hole on both sides of the square tube. The bolts are inserted into the first and second through holes of the fixing plate. The bolt inserted into the first through hole on one side of the fixing plate passes through the engine edge mounting plate. The bolt inserted into the second through hole on one side of the fixing plate continues to pass through the third adjustment groove on one side of the square tube. A nut is inserted into one side of the bolt to limit its position.

[0008] The effect achieved by the above components is as follows: When using the mounting assembly, the fixing plate moves on both sides of the square tube to align the third through hole on the square tube with the second through hole on the fixing plate, and the first through hole on the fixing plate with the engine bottom mounting plate. Then, several bolts are inserted into the first and second through holes of the fixing plate, and then several bolts pass through the third through holes on both sides of the engine bottom mounting plate and the square tube. Then, the nut threads are turned to the bolt surface to fix the bolt position. Then, the installation and fixing of the square tube and the engine are quickly completed. When disassembly is required, all bolts can be removed. By using the mounting assembly, the engine and the square tube can be installed and fixed, which makes it convenient for operators to use drilling equipment and to disassemble and replace the square tube and the engine.

[0009] Preferably, the first and second through holes on the fixing plate and the third through holes on both sides of the square tube are all elongated.

[0010] The effect achieved by the above components is that, since the first and second through holes on the fixing plate and the third through holes on both sides of the square tube are all elongated, the fixing plate can better align the holes, which facilitates subsequent installation and fixing with bolts.

[0011] Preferably, the second through hole at the upper end of the fixing plate is perpendicular to the third through hole on the square tube.

[0012] Preferably, the engine grip is raised near the sides of the engine.

[0013] The effect achieved by the above-mentioned components is that by raising the sides of the handle, the operator can hold the handle away from the engine position, thus allowing the operator to better support and use the engine.

[0014] Preferably, the square tube contains two internal circular rods, and the gears on the circular rods mesh with each other.

[0015] The effect achieved by the above components is as follows: by rotating two round rods inside the square tube, and with gears fixed on the two round rods meshing with each other, the two round rods can rotate simultaneously, thereby enabling the drilling device to drive the two drilling rods to drill holes at the same time, thus improving the efficiency of the drilling device.

[0016] Preferably, the drill rod is bent near the locking block and forms a semicircle.

[0017] The effect achieved by the above components is that by bending the drill rod near the locking block to form a semi-circle, the drill rod can be better locked into the locking block, thereby improving the performance of the drill rod.

[0018] Preferably, the connecting pipe is a universal accessory that is compatible with a variety of engines.

[0019] In summary, the beneficial effects of this utility model are as follows: When drilling in the ground, the operator holds the drilling device by gripping the handle on the outside of the engine, then starts the engine. The engine output drives the round rod to rotate inside the square tube through the connecting pipe. Then the round rod drives the gear fixed inside the square tube to rotate, and drives the locking block fixed on one side of the round rod to rotate. Then the drilling rod locked inside the locking block drives the auger fixed on one side to rotate on the ground, and then the ground drilling begins.

[0020] By using the mounting components, the engine and square tube can be installed and fixed, which makes it convenient for operators to use the drilling equipment and to disassemble and replace the square tube and the engine. Attached Figure Description

For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Figures 1 to 4 The illustrated hand-held ground drilling device includes an engine 1, a connecting pipe 2 at the output end of the engine 1, a round rod 3 on one side of the connecting pipe 2, a square tube 4 on one side of the round rod 3, a gear 5 on one side of the round rod 3, a locking block 6 at one end of the round rod 3, a drilling tube on one side of the locking block 6, an auger 8 on one side of the drilling rod, and mounting components 9 on both sides of the square tube 4. The mounting components 9 are used to install the engine 1 and the square tube 4. During ground drilling, the operator holds the drilling device by gripping the handle on the outside of the engine 1, then starts the engine 1. The output end of the engine 1, through the connecting pipe 2, drives the round rod 3 to rotate inside the square tube 4. The round rod 3 then drives the gear 5 fixed inside the square tube 4 to rotate, which in turn drives the locking block 6 fixed on one side of the round rod 3 to rotate. The drilling rod 7, locked inside the locking block 6, then drives the auger 8 fixed on one side to rotate on the ground. When it is necessary to replace the square tube 4, the mounting components 9 are used to disassemble and install the engine 1 and the square tube 4.

[0027] Figures 1 to 4 The mounting assembly 9 shown includes several bolts 91, nuts 92, a fixing plate 93, a first through hole 94 and a second through hole 95 on the fixing plate 93, and a third through hole 96 on both sides of the square tube 4. The bolts 91 are inserted into the first through hole 94 and the second through hole 95 of the fixing plate 93. The bolts 91 inserted into the first through hole 94 on one side of the fixing plate 93 will pass through the edge mounting plate of the engine 1. The bolts 91 inserted into the second through hole 95 on one side of the fixing plate 93 will continue to pass through the third adjustment groove on one side of the square tube 4. Nuts 92 are inserted into one side of the bolts 91 to limit the bolts 91.

[0028] Figures 1 to 4As shown, when using the mounting assembly 9, the fixing plate 93 moves on both sides of the square tube 4, aligning the third through hole 96 on the square tube 4 with the second through hole 95 on the fixing plate 93, and aligning the first through hole 94 on the fixing plate 93 with the bottom mounting plate of the engine 1. Then, several bolts 91 are inserted into the first through hole 94 and the second through hole 95 of the fixing plate 93 respectively. Then, several bolts 91 pass through the bottom mounting plate of the engine 1 and the third through holes 96 on both sides of the square tube 4 respectively. Then, the nut 92 is screwed onto the surface of the bolt 91 to fix the position of the bolt 91. Then, the installation and fixing of the square tube 4 and the engine 1 are quickly completed. When disassembly is required, all bolts 91 can be removed. By using the mounting assembly 9, the engine 1 and the square tube 4 can be installed and fixed, which makes it convenient for the operator to use the drilling device and to disassemble and replace the square tube 4 and the engine 1.

[0029] Figures 1 to 4 The first through hole 94 and the second through hole 95 on the fixing plate 93, and the third through hole 96 on both sides of the square tube 4, are all elongated. Because the first through hole 94 and the second through hole 95 on the fixing plate 93, and the third through hole 96 on both sides of the square tube 4 are all elongated, the fixing plate 93 can better align the holes, facilitating subsequent installation and fixing with bolts 91. The second through hole 95 at the upper end of the fixing plate 93 is perpendicular to the third through hole 96 on the square tube 4. The handle of the engine 1 is raised near the sides of the engine 1. This raised side design allows the operator to grip the handle further away from the engine 1, thus providing better support for the engine 1.

[0030] Figures 1 to 4 The square tube 4 shown contains two internal circular rods 3, with gears 5 on the rods 3 meshing with each other. By rotating the two circular rods 3 inside the square tube 4 and engaging the gears 5 on them, the two rods 3 can rotate simultaneously. This allows the drilling device to drive two drilling rods simultaneously for drilling, thus improving the efficiency of the drilling device. The drilling rod 7 is bent into a semi-circle near the locking block 6. This semi-circle bend allows the drilling rod 7 to better engage with the locking block 6, improving its performance. The connecting pipe 2 is a universal accessory, compatible with various engines 1.

[0031] Working principle: When drilling the ground, the operator holds the drilling device by gripping the handle on the outside of the engine 1, then starts the engine 1. The output end of the engine 1 drives the round rod 3 to rotate inside the square tube 4 through the connecting pipe 2. Then, the round rod 3 drives the gear 5 fixed inside the square tube 4 to rotate, and drives the locking block 6 fixed on one side of the round rod 3 to rotate. Then, the drilling rod 7 locked inside the locking block 6 drives the auger 8 fixed on one side to rotate on the ground. Then, the ground drilling is carried out. When the square tube 4 needs to be replaced, the installation component 9 is used to disassemble and install the engine 1 and the square tube 4.

[0032] When using the mounting assembly 9, the fixing plate 93 moves on both sides of the square tube 4, aligning the third through hole 96 on the square tube 4 with the second through hole 95 on the fixing plate 93, and aligning the first through hole 94 on the fixing plate 93 with the bottom mounting plate of the engine 1. Then, several bolts 91 are inserted into the first through hole 94 and the second through hole 95 of the fixing plate 93, and then the bolts 91 pass through the bottom mounting plate of the engine 1 and the third through holes 96 on both sides of the square tube 4. Then, the nut 92 is screwed onto the surface of the bolt 91 to fix the position of the bolt 91. Then, the installation and fixing of the square tube 4 and the engine 1 are quickly completed. When disassembly is required, all bolts 91 can be removed. By using the mounting assembly 9, the engine 1 and the square tube 4 can be installed and fixed, which makes it convenient for the operator to use the drilling device and to disassemble and replace the square tube 4 and the engine 1.
