Description

Technical Field

[0001] This utility model relates to the field of geological drilling equipment, specifically to a geological drilling and hole-making device. Background Technology

[0002] Drilling is an indispensable part of geological exploration and surface construction engineering, making geological drilling equipment widely used. Currently, most commercially available geological drilling equipment is small and portable. Its main function is to rotate the drilling auger, driven by the drilling machine, to drill holes in the ground. However, existing ground drilling equipment has several problems in practical use. Firstly, the height of the drilling auger is usually not adjustable, forcing operators to rely on visual observation of its position to estimate the drilling depth. However, the drilling auger generates significant oscillation during rotation, making precise control of the drilling depth difficult and easily leading to discrepancies between the drilled hole and the expected depth. Secondly, the handle controlling the drilling auger is located at the rear of the drilling machine, making it difficult for operators to visually observe the auger's position and drilling depth, further increasing the difficulty of controlling the drilling depth and reducing the efficiency of ground drilling.

[0003] Patent number CN213540379U uses an electro-hydraulic actuator and a sliding plate to adjust the drilling height of the auger drill pipe. Operation is simple and can be performed by a single worker. A multi-stage buffer structure provides cushioning and protection for the drilling device, reducing the impact of vibration. However, regarding drilling depth control, while the drilling height is adjusted primarily through the electro-hydraulic actuator and sliding plate, this method may still have some errors, especially when precise control of drilling depth is required. Secondly, regarding operational convenience, although the inclusion of a moving actuator and stabilizing device improves the device's mobility and stability, it does not solve the problem of operational convenience, particularly regarding the intuitiveness and accuracy of drilling depth control.

[0004] In summary, existing technologies still suffer from inaccurate drilling depth control and insufficient operational convenience. Therefore, a new technological solution is urgently needed to address these unresolved challenges and meet the market's and industry's pressing demand for efficient and precise drilling technology. Utility Model Content

[0005] The purpose of this invention is to provide a geological drilling device to overcome the shortcomings of existing technologies in terms of inaccurate drilling depth control and ease of operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A geological drilling and hole-making device includes a drilling machine body and a control mechanism installed on the drilling machine body;

[0008] The main body of the drilling machine includes a support frame, on which a drilling auger is mounted;

[0009] The control mechanism is installed on the back of the drilling machine body. The control mechanism includes a control plate, which is slidably connected to the support frame. A scale is also installed on the support frame, and the control plate is fitted onto the scale. A support block is also installed on the back of the support frame.

[0010] When positioning the drilling depth, the front end of the control plate passes through the support frame and contacts the drilling auger, while the bottom of the control plate contacts the support block.

[0011] A support is installed at the front end of the control board. When positioning the drilling depth, the control board contacts the drilling auger through the support.

[0012] The control box is fixedly connected to the back of the support frame, and the support block is arranged inside the control box.

[0013] The control box has a limit rod on its side, a movable plate on the limit rod, and a fixing hole on the movable plate. The support block is connected to the movable plate through the fixing hole.

[0014] A sliding plate is connected to the side of the support block, and the sliding plate has fixing holes.

[0015] A fixed bracket is connected to the movable plate, and a threaded rod is rotatably connected to the fixed bracket. Threaded holes are opened on the sliding plate and several threaded holes are opened on the movable plate. The threaded rod fixes the sliding plate and the movable plate through the threaded holes.

[0016] The movable plate is externally fixedly connected to a connecting plate, and the control plate is externally fixedly connected to a push rod. The connecting plate is located below the push rod.

[0017] The main body of the drilling machine also includes a motor assembly, which is connected to the drilling auger.

[0018] The scale intervals on the ruler are one centimeter.

[0019] The support block is made of high-strength alloy steel.

[0020] Compared with the prior art, the present invention has the following beneficial technical effects:

[0021] This invention provides a geological drilling device. By rotating the threaded rod, the support block is moved away from the control box. Then, according to the data information on the scale, the uppermost support block is moved to the long groove on the side of the control box. The threaded rod is then rotated again to move the support block into the control box. The motor on the top of the drilling machine is then turned on to rotate the drilling auger. When the control plate moves to the position above the support block, the support block will support and block the position of the control plate, thus preventing the drilling auger from moving downward. By adjusting the distance between the support block and the control plate according to the data on the scale, the support block will support and block the position of the moving control plate, preventing the drilling auger from moving downward after reaching the vicinity of the drilling depth. This avoids the problem of large errors caused by manually controlling the position of the drilling auger. Attached Figure Description

Detailed Implementation

[0028] Geological drilling equipment is used for underground exploration or surface construction. It is mainly used for drilling and processing the ground, and usually small, easily movable ground drilling equipment is used.

[0029] Existing ground drilling devices have the problem of difficulty in controlling drilling distance and position, thus reducing the efficiency of ground drilling.

[0030] The reason for this problem is that during the use of the drilling device, the motor assembly on top of the drilling machine needs to be turned on first. The motor assembly drives the drilling auger to rotate, and the handle at the rear of the drilling machine moves the rotating drilling auger slowly downwards to complete the drilling. To increase the drilling range of the drilling auger, the height of the drilling auger is not adjustable. When drilling to a certain depth, the position of the drilling auger needs to be observed visually to control the drilling depth in one go. However, the swing force generated by the drilling auger and the ground during rotation is relatively large, which makes it impossible to completely control the depth of the drilling auger after it enters the ground. This results in the drilling depth not meeting the expected effect. At the same time, the handle for controlling the drilling auger is located at the rear of the drilling machine, making it inconvenient to observe and control the position of the drilling auger and the drilling depth during drilling. Therefore, we propose a geological drilling device.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

[0035] Reference Figures 1 to 5 As shown, a geological drilling device is provided in a specific embodiment of the present invention, including a drilling machine body 1 and a control mechanism installed on the drilling machine body 1.

[0036] The main body 1 of the drilling machine includes a support frame 102, on which a drilling auger 101 is installed. The main body 1 of the drilling machine drives the drilling auger 101 to rotate and perform drilling operations. The drilling auger 101 serves as the actual drilling component, penetrating deep into the ground for drilling. The support frame 102 bears and supports the entire device, ensuring the stability and balance of the device.

[0037] The control mechanism is installed on the back of the drilling machine body 1. The control mechanism includes a control plate 2, which is slidably connected to the support frame 102. The control plate 2 is used to slide the control components, thereby controlling the drilling depth. A scale 201 is also installed on the support frame 102. The scale 2 provides position data for accurately measuring the movement distance of the control plate 2, thus controlling the drilling depth. The control plate 2 is fitted onto the scale 201. A support block 203 is also installed on the back of the support frame 102 to limit the movement distance of the control plate 2 and prevent the drilling auger 101 from moving excessively downwards.

[0038] When positioning the drilling depth, the front end of the control plate 2 passes through the support frame 102 and contacts the drilling auger rod 101, while the bottom of the control plate 2 contacts the support block 203.

[0039] The control board 2 has a support 207 installed at its front end. When positioning the drilling depth, the control board 2 contacts the drilling auger 101 through the support 207.

[0040] A control box 202 is fixedly connected to the back of the support frame 102. The control box 202 is used to install and accommodate components such as the control board 2 and the limit rod 204, and serves to protect and limit them. The support block 203 is arranged inside the control box 202.

[0041] A limit rod 204 is provided on the side of the control box 202. A movable plate 210 is provided on the limit rod 204. The movable plate 210 has a fixing hole, and the support block 203 is connected to the movable plate 210 through the fixing hole. The limit rod 204 is used to limit the movement range of the movable plate 210 to ensure the stable movement of the support block 203. The movable plate 210 acts as an intermediate transmission component, converting the rotation of the threaded rod 209 into the movement of the sliding plate 205.

[0042] The support block 203 is connected to a sliding plate 205 on its side, and the sliding plate 205 has a fixing hole.

[0043] A fixed bracket 211 is connected to the movable plate 210. A threaded rod 209 is rotatably connected to the fixed bracket 211. The fixed bracket 211 supports and fixes the threaded rod 209, ensuring its stable rotation. A threaded hole is formed on the sliding plate 205, and several threaded holes are formed on the movable plate 210. The threaded rod 209 fixes the sliding plate 205 and the movable plate 210 through these threaded holes. The sliding plate 205 connects the support block 203 and the threaded rod 209. The rotation of the threaded rod 209 moves the support block 203. The rotation of the threaded rod 209 drives the sliding plate 205 to move, thereby adjusting the position of the support block 203.

[0044] A connecting plate 206 is fixedly connected to the external side of the movable plate 210, and a push rod 208 is fixedly connected to the external side of the control plate 2. The connecting plate 206 is located below the push rod 208. The connecting plate 206 connects the sliding plate 205 and the push rod 208, transmitting power. The push rod 208 is used to manually push the control plate 2 and the support member 207 to move, thereby driving the drilling machine body 1 and the drilling auger 101 to move.

[0045] It should be noted that the main body 1 of the drilling machine also includes a motor assembly for driving. The motor assembly is connected to the drilling auger 101 and drives the drilling auger 101 to perform drilling operations.

[0046] The scale 201 has a scale interval of one centimeter, which is used to accurately measure the moving distance of the control plate 2, thereby accurately controlling the drilling depth of the drilling auger 101.

[0047] In this embodiment, the support block 203 is made of high-strength alloy steel, which has wear-resistant and corrosion-resistant properties to ensure that it maintains accurate support and limiting functions during long-term use.

[0048] Specifically, this utility model also provides a usage scenario for a geological drilling device. When using the device described in this utility model for geological drilling operations, firstly, by rotating the threaded rod 209, the threaded rod 209 drives the sliding plate 205 to move. At this time, the threaded rod 209 will rotate inside the fixed bracket 211 and on the front of the movable plate 210. During rotation, the threaded rod 209 moves its thread inside the sliding plate 205, and the rotation of the threaded rod 209 will also drive the sliding plate 205 to move until the support block 203. As the threaded rod 209 leaves the control box 202, the position of the movable plate 210 is then moved, causing the movable plate 210 to move the support block 203. At this time, the movable plate 210 will also slide outside the limit rod 204. According to the data information on the scale 201, the position of the uppermost support block 203 is moved to the long groove on the side of the control box 202. Then, the threaded rod 209 is rotated again to move the sliding plate 205, causing the sliding plate 205 to move the support block 203 and insert it into the control box 202. Then, the drilling machine body 1 is opened. The upper motor drives the drilling auger 101 to rotate, pushing the push rod 208 downwards. This causes the push rod 208 to move the control plate 2 and support member 207 downwards. Simultaneously, the downward movement of the support member 207 also moves the drilling machine body 1 and the drilling auger 101. As the drilling auger 101 rotates, it enters the ground to perform drilling. When the control plate 2 moves above the support block 203, the support block 203 supports and blocks the control plate 2, preventing the drilling auger 101 from moving further downwards and reducing drilling speed. To address the deviation in hole depth, a support block 203 is installed inside the control box 202. This support block 203 adjusts the distance between itself and the control plate 2 based on the data from the scale 201. Then, a threaded rod 209 is used to fix the position of the support block 203. Subsequently, the support block 203 supports and blocks the position of the moving control plate 2, preventing the drilling auger 101 from continuing to move downwards after reaching the vicinity of the drilling depth. This avoids the problem of large errors caused by manually controlling the movement of the drilling auger 101, and is simple to use.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
