Description

TECHNICAL FIELD

[0001] The utility model relates to the geophysical prospecting device field, specifically is a kind of geophysical prospecting equipment for punching. BACKGROUND

[0002] In the process of geophysical exploration, the sampling link is an important means to obtain underground geological information. Explorers usually need to use portable devices to drill and sample soil and rock in order to analyze geological information such as underground material composition and structural characteristics. However, in actual operation, ordinary drilling devices are often limited by drill bit length and cannot obtain sampling materials at a specific depth, which poses a significant challenge to exploration work.

[0003] The working principle of ordinary drilling devices is mainly to cut and break underground materials through the rotation and advancement of the drill bit, thereby achieving sampling. However, the length of the drill bit is limited, and when the sample to be collected is located in a deeper stratum, ordinary drilling devices often cannot reach the required depth. This results in explorers being unable to obtain geological information at a specific depth, thereby affecting the accuracy and completeness of the exploration results. To address this issue, an extension rod is currently used to extend the effective length of the drill bit. The extension rod is a device that can effectively extend the drill bit and comes in various sizes and shapes, allowing for selection based on different needs. However, as the extension rod is extended, the swing at the end of the drill rod increases, which can cause jamming and clogging problems.

[0004] Therefore, there is an urgent need for a new type of geophysical prospecting equipment for punching that provides an effective solution to the deficiencies of existing technology. INVENTION CONTENTS

[0005] The purpose of the present utility model is to provide a drilling device for geophysical prospecting to solve the problems raised in the background art.

[0006] To achieve the above-mentioned purpose, the present utility model provides the following technical solutions:

[0007] A drilling device for geophysical prospecting includes a drill rig, which is a percussion and non-percussion dual-purpose drill rig. A rotary knob for switching modes is provided on the sidewall of the drill rig's body. A handle is provided at the tail of the drill rig, and a drill bit holder is provided at the head of the drill rig. The drill bit holder is used to hold the tail of the drill rod of the drill bit. An externally extending external plate is detachably installed at the end of the drill bit holder. A bearing sleeve is provided at the center of the external plate, and a bearing is installed in the bearing sleeve. The tail of the drill rod of the drill bit is slidingly installed in the bearing.

[0008] Furthermore, the outer plate is provided with four parallel rods, and each of the parallel rods is provided with a bracket extending to the right at the end away from the outer plate. The bracket is provided with a U-shaped groove with the opening facing downward. The end of the drill bit chuck is provided with a hanging plate seat. Four locking bolts are threaded onto the hanging plate seat. The U-shaped groove of the hanging plate is engaged with the locking bolts. After the locking bolts are tightened, the hanging plate is locked.

[0009] Furthermore, the drill bit is an extendable drill bit with a replaceable cutting head.

[0010] Furthermore, the drill bit includes a tail rod, a head rod, and one or more extension rods. The tail rod, head rod, and extension rods are all connected by threads, and adjacent extension rods are connected by threads. The cutting head is located at the end of the head rod.

[0011] Furthermore, the end of the head rod is provided with an annular sampling head, and a carbide blade is fixedly installed on the end face of the sampling head.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figs. 1-3 A drilling device for geophysical exploration includes a drill rig 1, which is a dual-purpose drill rig for both impact and non-impact applications. The drill rig 1 has a knob 4 on its side wall for switching modes, a handle 2 at its tail, and a drill bit chuck 3 at its head. The drill bit chuck 3 is used to hold the tail of the drill rod of a drill bit 6. An external plate 12 is detachably installed at the end of the drill bit chuck 3. A bearing sleeve 13 is provided at the center of the external plate 12, and a bearing 14 is installed inside the bearing sleeve 13. The tail of the drill rod of the drill bit 6 is slidably installed in the bearing 14.

[0024] The outer plate 12 is provided with four parallel rods 15. Each parallel rod 15 has a hanging seat 16 extending to the right at the end away from the outer plate 12. The hanging seat 16 has a U-shaped groove 17 with the opening facing downward. The drill bit chuck 3 has a hanging plate seat 5 at the end. The hanging plate seat 5 is threaded with four locking bolts 18. The U-shaped groove 17 of the hanging seat 16 is engaged with the locking bolts 18. After the locking bolts 18 are tightened, the hanging seat 16 is locked.

[0025] Working principle of this embodiment:

[0026] In this embodiment, during operation, the exploration personnel first grip the drill rig 1 using handle 2 and switch between impact and non-impact modes using knob 4 as needed. The drill rod tail of the drill bit 6 is clamped in the drill bit chuck 3. An external plate 12 is detachably installed at the end of the drill bit chuck 3. A bearing 14 is installed inside the bearing sleeve 13 on the external plate 12. The drill rod tail of the drill bit 6 slides in the bearing 14, which allows the drill bit to maintain a certain stability during drilling and reduces swaying caused by extension. The external plate 12 is connected to the mounting bracket 16 via four parallel rods 15. The U-shaped groove 17 below the mounting bracket 16 engages with the locking bolt 18 on the mounting plate seat 5 at the end of the drill bit chuck 3. When the locking bolt 18 is tightened, the mounting bracket 16 is securely locked, thereby further stabilizing the external plate 12 and the drill bit 6.

[0027] This embodiment effectively reduces the swaying of the drill rod end through the design of the external plate 12 and its bearing 14, avoiding jamming and blockage problems caused by extension, and improving drilling stability and efficiency. The bracket 16 of the external plate 12 is detachably installed by bolts, and the external plate 12 with different extension distances can be replaced according to usage requirements. The drilling rig 1 has two modes: impact and non-impact. The impact mode can be selected during drilling, and the sampling drill bit can be replaced when drilling reaches the sampling position to use the non-impact mode for sampling. This embodiment effectively solves the depth limitation and stability problems in the prior art, and improves the accuracy and efficiency of exploration work.

[0028] Example 2: Please refer to Figs. 4-6 A drilling device for geophysical exploration, which differs from Embodiment 1 in that the drill bit 6 is an extendable drill bit with a replaceable cutting head.

[0029] The drill bit 6 includes a tail rod 7, a head rod 9, and one or more extension rods 8. The tail rod 7 and the head rod 9 are connected to the extension rods 8 and adjacent extension rods 8 by threads. The cutting head is located at the end of the head rod 9.

[0030] The end of the head rod 9 is provided with an annular sampling head 10, and a carbide blade 11 is fixedly installed on the end face of the sampling head 10.

[0031] The working principle of this implementation is as follows:

[0032] The drill bit 6 consists of a tail rod 7, one or more extension rods 8, and a head rod 9. These components are connected by threads, allowing explorers to adjust the overall length of the drill bit as needed. When samples need to be collected from deeper formations, extension rods 8 can be added to increase the drill bit length. The cutting head is located at the end of the head rod 9, specifically an annular sampling head 10, on which a carbide cutting edge 11 is fixedly mounted. Due to its high hardness and wear resistance, the carbide cutting edge 11 can efficiently cut and break underground materials. When the cutting edge wears out or a different type of cutting surface is required, a new carbide cutting edge 11 or the entire sampling head 10 can be easily removed and replaced.

[0033] This embodiment, with its extendable drill bit structure and replaceable cutting head, can adapt to geological sampling needs at different depths and of different types. Exploration personnel can flexibly adjust the drill bit length and the type of cutting head according to actual conditions, improving the versatility and practicality of the device.
