Description

Technical Field

[0001] This utility model relates to the field of geological drilling technology, specifically to a portable drilling device for hydrogeological drilling. Background Technology

[0002] Hydrogeology is the science that studies groundwater. It primarily investigates the distribution and formation patterns of groundwater, its physical properties and chemical composition, groundwater resources and their rational utilization, and the adverse effects of groundwater on engineering construction, geological exploration, mining, and geological hazards, as well as their prevention and control. During hydrogeological investigations and explorations, drilling machines are used to obtain various hydrogeological research parameters. Existing hydrogeological drilling equipment includes both large and small machines, but all have some technical limitations.

[0003] First, while large drilling machines are highly stable, they are bulky and inconvenient to carry; small portable devices generally suffer from weak support and limited functionality, making it difficult to meet the precision requirements of hydrogeological drilling.

[0004] Secondly, traditional portable drilling machines rely heavily on manual pressing to provide feed force. When working in the field, technicians need to continuously exert force to push the drill rod downwards. Prolonged operation can easily lead to fatigue, and it is difficult to ensure a uniform feed speed. In addition, the lack of reliable support and adjustment components means that the drill rod is prone to deviation due to uneven ground or vibration during drilling, which affects drilling accuracy and may even cause the drill to be skewed.

[0005] Furthermore, the drilling depth of existing equipment largely relies on manual experience and cannot be precisely controlled; angle adjustment requires additional auxiliary tools, resulting in insufficient flexibility to adapt to complex terrains. Utility Model Content

[0006] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a portable drilling device for hydrogeological drilling that is stable, easy to operate, adjustable in depth and angle, and can reduce labor intensity.

[0007] The technical solution adopted by this utility model is: a portable drilling device for hydrogeological drilling, including a drilling assembly and a support adjustment assembly; the drilling assembly includes a drive module, the output end of which is connected to a speed change module, the output end of which is connected to a drill rod, and a drill bit is installed at the bottom of the drill rod; the support adjustment assembly includes a handheld mounting platform that fixes the drive module and the speed change module, a support screw arranged parallel to the drill rod is movably inserted through the handheld mounting platform corresponding to the outer side of the drill rod, a rotating sleeve adapted to the thread of the support screw is rotatably provided inside the handheld mounting platform, and an adjustment handle is rotatably provided outside the handheld mounting platform, the adjustment handle and the rotating sleeve are connected by a bevel gear set, and rotating the adjustment handle can move the handheld mounting platform up and down along the support screw.

[0008] In this technical solution, the drive module and speed change module of the drilling component can be arranged on the handheld mounting platform. When the drive module is running, it transmits the speed to the drill rod through the speed change module to realize drilling. The handheld mounting platform can move up and down along the support screw by adjusting the handle rotation, and can stop at any position on the support screw, which facilitates the adjustment of the drilling depth. During the drilling process, the support screw provides support, and the technician only needs to control the drilling depth and direction, thereby effectively reducing the labor intensity of the drilling personnel.

[0009] Preferably, the upper end of the drill rod is connected to the output end of the speed change module via a coupling.

[0010] Preferably, the bottom of the support screw is provided with a support plate, the upper end of the support plate is provided with an adjustment groove, a rotating ball is rotatably provided in the adjustment groove, and the rotating ball is fixedly connected to the bottom of the support screw.

[0011] Preferably, the bottom of the support plate is provided with several fixing grooves, and a detachable fixing post is inserted into the fixing groove.

[0012] Preferably, the bottom of the handheld mounting platform is provided with a sliding opening for the support screw to pass through, and a cleaning ring sleeved on the support screw is engaged in the sliding opening. A cleaning brush that contacts the support screw is provided inside the cleaning ring.

[0013] Preferably, the handheld mounting platform has bearing seats at both ends of the rotating sleeve for rotating the sleeve.

[0014] Preferably, the handheld mounting platform has symmetrically arranged grip handles on both sides of its bottom.

[0015] The beneficial effects of this utility model are as follows: Through the depth adjustment structure of the handle, bevel gear set, rotating sleeve, and support screw, this utility model eliminates the need for manual pressing during drilling. Simply rotating the adjustment handle drives the handheld mounting platform to move smoothly up and down along the support screw, precisely controlling the drilling depth. It can also stop and position itself at any location, completely solving the defects of traditional equipment such as tiring manual pressing and difficulty in controlling depth, significantly reducing operator fatigue. The drilling machine adopts a modular design with high integration of components, resulting in a compact size and light weight, facilitating field transportation and carrying. The symmetrical grip handles on both sides of the handheld mounting platform, combined with the single-handed adjustment handle, allow technicians to control the drilling direction and depth with both hands, avoiding safety hazards caused by equipment deviation during drilling and improving operational stability and safety. It has high practical value. Attached Figure Description

Detailed Implementation

[0020] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0021] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0022] like Figure 1 and Figure 2 As shown in the figure, a specific embodiment of this utility model provides a portable drilling device for hydrogeological drilling; it includes a drilling component and a support adjustment component; each component is modularly designed, making assembly and disassembly convenient, and can quickly complete the preparation for field operations.

[0023] like Figure 1As shown, the drilling assembly includes a drive module 100, a transmission module 200, a drill rod 300, a drill bit 400, and a coupling 1000, used for power output and drilling operations. The drive module 100 can be a small, high-power DC motor or a small gasoline engine, powered by an external power source. The drive module 100 is bolted to the upper surface of the handheld mounting platform 500, and its output shaft is connected to the input end of the transmission module 200 via a keyway. The transmission module 200 is a gearbox with an adjustable transmission ratio to adapt to drilling requirements under different geological conditions (e.g., high speed for soft soil, high torque for weathered rock). The transmission module 200 is fixed to the upper surface of the handheld mounting platform 500, arranged side-by-side with the drive module 100, and its output end has a flange, connected to the drill rod 300 via the coupling 1000.

[0024] In practical applications, the drill pipe 300 is made of high-strength alloy steel pipe, and the drill bit 400 is a carbide drill bit 400. Depending on geological conditions, it can be replaced with a spiral drill bit 400 (suitable for soil and sand layers) or a diamond drill bit 400 (suitable for weathered rock layers). The coupling 1000 is a flexible coupling 1000, with both ends interference-fitted with the output shaft of the speed change module 200 and the connecting shaft of the drill pipe 300, respectively, to compensate for installation deviations, ensure stable transmission, and facilitate quick disassembly and replacement of the drill pipe 300.

[0025] like Figure 1 As shown, the support adjustment assembly provided in this embodiment includes a handheld mounting platform 500 of a fixed drive module 100 and a transmission module 200. A support screw 600, arranged parallel to the drill rod 300, is movably inserted through the handheld mounting platform 500 on the outer side of the drill rod 300. A rotating sleeve 700, threadedly adapted to the support screw 600, is rotatably provided inside the handheld mounting platform 500. An adjustment handle 800 is rotatably provided outside the handheld mounting platform 500. The adjustment handle 800 and the rotating sleeve 700 are connected via a bevel gear set 900. Rotating the... Figure 1 As shown, adjusting the handle 800 allows the handheld mounting platform 500 to move up and down along the support screw 600.

[0026] With the above setup, the drive module 100 and the speed change module 200 of the drilling assembly can be arranged on the handheld mounting platform 500. When the drive module 100 is running, it transmits the speed to the drill rod 300 after changing speed through the speed change module 200 to achieve drilling. The handheld mounting platform 500 can be moved up and down along the support screw 600 by adjusting the handle 800 and can be stopped at any position on the support screw 600, which facilitates the adjustment of the drilling depth. During the drilling process, the support screw 600 provides support, and the technician only needs to control the drilling depth and direction, thereby effectively reducing the workload of the drilling personnel.

[0027] like Figure 1As shown, in order to improve the support stability of the support screw 600, this embodiment provides a support plate 1100 at the bottom of the support screw 600. The support plate 1100 is a steel plate structure with an annular adjustment groove at the upper end. A rotating ball 1200 is rotatably installed in the adjustment groove. The rotating ball 1200 is welded and fixed to the bottom of the support screw 600, so that the support screw 600 can be adjusted at any angle of 360°. A fixing groove is evenly provided at the bottom of the support plate 1100. A detachable fixing column 1300 can be inserted into the fixing groove. After being inserted into the ground, it enhances the support stability and prevents the support plate 1100 from shaking or displacing, which is beneficial to improving the drilling accuracy.

[0028] like Figure 1 As shown, in this embodiment, a sliding opening is provided at the bottom of the handheld mounting platform 500 for the support screw 600 to pass through. A cleaning ring 1400 is fitted onto the support screw 600 through the sliding opening. The cleaning ring 1400 is made of rubber and is fitted into the sliding opening at the bottom of the handheld mounting platform 500 during installation. A nylon cleaning brush is provided on the inner side, and the brush is in close contact with the surface of the support screw 600. When the handheld mounting platform 500 moves up and down, the cleaning brush can automatically remove dust and dirt from the surface of the support screw 600 to prevent the threads from getting stuck.

[0029] Meanwhile, the handheld mounting platform 500 has bearing seats at both ends of the rotating sleeve 700 for rotating the rotating sleeve 700. When the adjusting handle 800 is rotated, the rotating sleeve 700 is driven to rotate circumferentially through the bevel gear set 900, thereby reducing the rotational friction of the rotating sleeve 700.

[0030] This embodiment also features symmetrically arranged grip handles 1500 on both sides of the bottom of the handheld mounting platform 500. During drilling, technicians can rotate the adjustment handle 800 with one hand to adjust the drilling depth, while holding the grip handle 1500 with the other hand to ensure drilling stability. The grip handles 1500 are fixed to both sides of the bottom of the handheld mounting platform 500 and are covered with anti-slip rubber sleeves to facilitate technicians holding and stabilizing the equipment.

[0031] When using this device, technicians first select a drilling location, place the support plate on a flat surface, and insert the fixing post into the fixing groove at the bottom of the support plate according to the ground hardness, ensuring the fixing post is deeply embedded in the ground and providing stable support. The angle of the support screw is adjusted by rotating the ball to align the drill rod with the drilling position and the preset angle. During drilling, the drive module is activated, and the speed and torque are adjusted to suit the geological conditions via the speed change module. The technician holds the handle with one hand to stabilize the device, and rotates the adjustment handle with the other hand to drive the handheld mounting platform slowly downwards along the support screw. The drill rod drives the drill bit to rotate and drill the hole. The downward speed is controlled by adjusting the handle as needed to ensure uniform drilling. The drilling depth is precisely controlled by adjusting the number of rotations of the handle. Once the preset depth is reached, the adjustment handle is rotated in the opposite direction to return the handheld mounting platform to its original position, and the drive module is turned off. After drilling is complete, the dirt on the drill bit is cleaned. If the drill bit needs to be replaced, it can be replaced by disassembling the coupling. The surface of the support screw is cleaned, and the fixing post is pulled out of the fixing groove. The entire device can be stored in a suitable storage bag for easy transport.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
