Description

Technical Field

[0001] This utility model belongs to the technical field of geological exploration instruments, specifically relating to a geological hammer for geological exploration. Background Technology

[0002] Geological exploration, as a fundamental part of geological work, requires detailed investigation of geological features such as rocks and stratigraphic structures. Traditional geological hammers typically have a fixed structure, offering limited functionality and being inconvenient to carry. In actual exploration, geologists often need to use both planar hammering and cone-shaped breaking functions simultaneously, but existing tools often require carrying two different hammers, increasing the burden of fieldwork. Furthermore, the fixed handle structure of traditional geological hammers prevents angle adjustment for different operational needs, causing inconvenience when working in confined spaces. The anti-slip performance and stability of the hammer also directly affect safety, especially in wet or dusty environments, where the anti-slip design of existing hammers often fails to meet requirements. Therefore, existing technologies urgently need improvement to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a geological hammer for geological exploration, which aims to solve the problems mentioned in the background art.

[0021] 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.

[0022] In existing technologies, geological exploration operations require carrying multiple tools for extended periods to cope with varying rock conditions, but traditional geological hammers are equipped with only a single hammerhead structure. When encountering complex rock formations requiring alternating use of planar hammering and conical chisels, geologists must carry both tools simultaneously. This not only increases the load but also disrupts the continuity of work due to frequent tool changes. Especially in steep terrain, the inconvenience of tool storage can easily lead to safety hazards.

[0023] To address these issues, designers observed the space-saving advantages of folding tools and attempted to integrate two types of hammer heads into a convertible structure. Analysis of the force transmission path during hammering revealed that the rotating connection structure needed to simultaneously satisfy rigidity when unfolded and compactness when folded. To mitigate the risk of accidental unfolding in the folded state, a mechanical locking device was proposed for the grip area.

[0024] Therefore, as Figure 1-4 As shown, this application proposes a technical solution comprising a first hammer handle and a second hammer handle that are rotatably connected. The first hammer handle has a flat hammer head at its end, and the second hammer handle has an arc-shaped conical head at its end. A limiting mechanism is provided at the gripping part. The inner sides of the two hammer handles are respectively arranged with staggered crushing teeth, and the outer sides are covered with anti-slip sleeves.

[0025] The rotatable connection refers to the relative rotation of the two hammer handles via an axial connecting component. A shaft structure with reinforced end rings can be used to ensure the torsional strength of the connection during hammering. The limiting mechanism fixes the hammer handle's unfolding angle through the cooperation of an elastic element and a positioning pin. Specifically, a spring-driven limiting pin can be inserted into different positioning holes. The staggered crushing teeth refer to the crushing protrusions on the inner sides of the two hammer handles forming complementary clamping surfaces when closed. A combination of triangular tooth peaks and trapezoidal tooth grooves can enhance the stone-crushing effect. The anti-slip sleeve is an elastic material layer wrapped around the grip area; a corrugated surface design can increase the coefficient of friction.

[0026] Specifically, the flat hammer head and the arc-shaped conical head are fixed to the ends of two foldable hammer handles. When the hammer handles are unfolded into a straight state, the positioning pins of the limiting mechanism insert into the corresponding holes to form a rigid structure, allowing for conventional hammering operations. To switch to the conical chisel function, the limiting mechanism is released, and the second hammer handle is rotated to a predetermined angle and relocked. At this point, the flat hammer head of the first hammer handle and the arc-shaped conical head of the second hammer handle form a working angle. In the closed state, the crushing teeth on the inner sides of the two hammer handles mesh together to form a rock-crushing clamp structure, allowing for direct crushing of small rocks.

[0027] Compared to existing technologies, the fixed hammerhead of traditional geological hammers cannot adapt to the needs of multi-terrain operations, while this solution achieves multiple uses with a single hammer through an adjustable dual-hammerhead structure. Conventional folding tools lack reliable unfolding and locking devices; this solution's limiting mechanism ensures structural stability during hammering operations through a multi-positioning design. Ordinary rock crushers need to be carried separately; this solution automatically forms a crushing structure in the folded state, reducing the number of tools required.

[0028] Through the above technical solution, this application integrates three functions—planar hammering, conical chiseling, and rock clamping—into a single tool, eliminating the time wasted on frequent tool changes. The folding structure reduces storage volume by more than 50%, facilitating transport in confined terrain. The multi-positioning design of the limiting mechanism allows the hammer head angle to be flexibly adjusted according to the rock hardness, improving crushing efficiency. The staggered crushing teeth form a continuous crushing surface when closed, preventing rock fragments from slipping during the crushing process.

[0029] This application further proposes that both ends of the connecting shaft are fixedly connected with reinforcing rings, and the cross-sectional area of ​​the reinforcing rings is larger than the cross-sectional area of ​​the connecting shaft.

[0030] The reinforcing ring refers to the ring-shaped structure fixed at both ends of the connecting shaft. It can be made by welding or integrally molding a metal ring of the same material as the connecting shaft. Its function is to enhance the structural strength between the connecting shaft and the hammer handle. The cross-sectional area refers to the cross-sectional area of ​​the reinforcing ring in the direction perpendicular to the axial direction. This can be achieved by increasing the radial thickness or outer diameter of the ring structure. Its function is to distribute the stress concentration generated during the rotation of the connecting shaft by increasing the contact area.

[0031] Specifically, the reinforcing ring is designed to cover the rotating connection area between the connecting shaft and the first and second hammer handles. When the hammer handle rotates under external force, the design of the reinforcing ring having a larger cross-sectional area than the connecting shaft ensures that the stress transmission path transitions from the connecting shaft to the reinforcing ring, thus preventing structural deformation or breakage due to excessive local stress at the connection between the connecting shaft and the hammer handle. In field operations, geological hammers frequently bear the reaction force of striking rocks; the reinforcing ring, by increasing the bending stiffness of the contact surface, can effectively extend the service life of the connecting shaft.

[0032] Through the above technical solution, this application can significantly improve the structural stability of the geological hammer connecting shaft, prevent the problem of cracking at the end of the connecting shaft due to repeated hammering, and enable the rotating mechanism of the hammer handle and connecting shaft to maintain reliable operation under complex field conditions, thereby reducing the frequency of tool maintenance.

[0033] This application further proposes a geological hammer for geological exploration, wherein a plurality of first crushing teeth are installed at equal intervals on the surface of a first hammer handle, a plurality of second crushing teeth are installed at equal intervals on the surface of a second hammer handle, and the plurality of first crushing teeth and the plurality of second crushing teeth are staggered.

[0034] Equal-distance installation means that the spacing between adjacent crushing teeth remains consistent. This can be achieved by setting mounting holes or slots with fixed spacing on the surfaces of the first and second hammer handles to ensure the uniformity of the crushing tooth distribution. Staggered installation means that the first and second crushing teeth are arranged at different spatial positions. This can be achieved by adjusting the relative angles of the first and second hammer handles when they are closed, so that the tips of the two sets of crushing teeth do not overlap, thereby increasing the contact area.

[0035] Specifically, when the first and second hammer handles rotate and close via the connecting shaft, the staggered distribution of the first and second crushing teeth creates complementary crushing zones upon contact with the rock. Because the tips of the two sets of crushing teeth are staggered, the number of contact points on the rock surface covered by the crushing teeth increases during hammering, thereby improving the crushing efficiency of a single hammer strike. Furthermore, the staggered structure avoids wear on the crushing teeth caused by direct impact, extending their service life.

[0036] This solution combines equidistant installation with staggered arrangement to make the crushing teeth more evenly distributed, reduce energy loss in areas of repeated contact, reduce the risk of rock debris splashing, and improve operational stability.

[0037] Through the above technical solution, this application solves the problems of low crushing efficiency and easy wear of the crushing tips caused by the unreasonable distribution of crushing teeth in existing geological hammers. By using a staggered crushing tooth structure, the rock surface is more evenly covered, and a single hammer blow can create multi-directional cracks, reducing the number of repeated blows and thus improving the efficiency of geological exploration operations. Furthermore, the staggered layout of the crushing teeth can disperse impact stress, avoid local overload, and further ensure the tool's service life.

[0038] This application further proposes that both the surface of the first hammer handle and the second hammer handle are provided with L-shaped grooves, and the first hammer handle and the second hammer handle are fitted together through the L-shaped grooves.

[0039] The L-shaped groove refers to a groove structure formed by a combination of vertical and horizontal sections. It can be formed on the surface of the hammer handle using milling or stamping processes, and its depth and width can be adjusted according to the thickness of the hammer handle. This structure allows the two hammer handles to nest and fit together when folded, reducing space occupation. "Fitting together" means that the contact surfaces of the two hammer handles form a gapless fit in the folded state, which can be achieved by adjusting the machining precision of the L-shaped groove. This design maintains the stability of the hammer body structure while preventing wobbling between the hammer handles after folding.

[0040] Specifically, when the hammer is in its unfolded working state, the vertical sections of the L-shaped grooves of the two hammer handles align with each other, forming a continuous support surface to transmit the striking force. During the folding and storage process, the second hammer handle rotates along the connecting shaft, and its horizontal section of the L-shaped groove slides into contact with the horizontal section of the first hammer handle, ultimately causing the L-shaped grooves of the two hammer handles to fully engage. The contact surface constraint at the edge of the grooves prevents unintended unfolding during the folding process.

[0041] Through the above technical solution, this application reduces the volume of the geological hammer by approximately 40% when folded, making it easier to pack into a tool bag for carrying. The interlocking structure of the two hammer handles prevents wear and tear on components caused by vibration during transportation, extending the tool's service life. This design is particularly suitable for geological exploration scenarios that require frequent switching of working states, allowing the operator to unfold or fold the hammer with one hand.

[0042] This application further proposes a limiting mechanism including a protective shell installed on the surface of the handle, a limiting ring slidably connected to the inner wall of the protective shell, two mounting plates installed on the surface of the limiting ring, two return springs installed on the surface of the mounting plates, a limiting post installed on the outer end of the return spring through the limiting plate, and multiple limiting grooves adapted to the limiting post on the surface of the protective shell.

[0043] The protective shell refers to the outer shell structure installed on the handle surface, which can be made of stamped metal or injection-molded engineering plastic, and is used to house the limiting mechanism components and provide protection. The limiting ring is a ring-shaped sliding component nested within the protective shell, which can be made of a metal ring structure with guide grooves, and is used to support the mounting plate and allow axial displacement. The return spring is a mechanical element with elastic return function, which can be made of a helical compression spring or a disc spring, and is used to provide the positioning and holding force of the limiting post. The limiting groove is an array of positioning holes formed on the surface of the protective shell, which can be made of equidistantly distributed circular through holes or rectangular grooves, and is used to selectively engage with the limiting post.

[0044] Specifically, when adjusting the unfolding angle of the second hammer handle, the limiting ring is pushed to slide along the inner wall of the protective shell, causing the mounting plate to compress the return spring. At this time, the limiting post moves synchronously with the limiting plate, disengaging from the constraint of the current limiting groove. When the second hammer handle rotates to the target angle, the pushing force is released, causing the return spring to push the limiting post into the corresponding limiting groove, forming a new positioning state. Multiple limiting grooves are spaced apart along the length of the protective shell, providing multi-level adjustment functionality.

[0045] This solution achieves rapid angle adjustment with one hand through the combination of spring reset and sliding limit structure, while the array design of the limit grooves significantly improves positioning reliability.

[0046] Through the above technical solution, this application effectively solves the problem of the single function of traditional geological hammers. While maintaining the portability of the tool, it achieves rapid and precise adjustment of the hammer angle through a multi-position limiting mechanism. This structure can adapt to different geological sampling needs in field operations, significantly improving the operational efficiency of rock crushing and sample collection.

[0047] This application further proposes that the surface of the limiting ring has two first sliding grooves, and the surface of the limiting plate is equipped with a push plate, and the push plate is slidably connected to the surface of the first sliding grooves.

[0048] The first sliding groove refers to a long, narrow groove structure on the surface of the limiting ring, which can be achieved by machining or stamping, and serves to provide a guiding path for the sliding of the push plate. The push plate is a plate-shaped component fixed to the limiting plate, which can be achieved by welding or bolting, and serves to convert the movement of the limiting plate into the sliding of the push plate, thereby controlling the extension and retraction of the limiting post.

[0049] Specifically, when the limiting ring slides within the protective shell, the pushing plate moves along the trajectory of the first sliding groove. The constraint of the sliding path ensures that the limiting post maintains linear movement under the action of the return spring. The guiding function of the first sliding groove ensures that the pushing plate does not deviate during sliding, thus guaranteeing precise alignment between the limiting post and the limiting groove. This structure allows the limiting mechanism to be stably locked when adjusting the position of the second hammer handle, preventing accidental unlocking due to vibration or external force.

[0050] This solution achieves precise guidance and stable extension and retraction of the limiting column through the cooperation of the first sliding groove and the push plate, significantly improving the smoothness and reliability of operation.

[0051] Through the above technical solution, this application solves the problems of difficult adjustment and easy failure of the existing geological hammer limiting mechanism. Through the synergistic effect of the sliding groove and the push plate, the extension and retraction of the limiting column is made more stable and controllable, thereby ensuring that the second hammer handle can be reliably fixed in the folded or unfolded state, and adapting to the needs of different geological operation scenarios.

[0052] This application further proposes that the surface of the protective shell has multiple second sliding grooves, and the second sliding grooves are adapted to the push plate.

[0053] The second sliding groove refers to an elongated opening structure on the surface of the protective shell, which can be implemented using a straight or arc-shaped channel structure. Its width and depth match the size of the push plate, and it is used to guide the push plate to slide along a predetermined trajectory. The push plate refers to a plate-shaped component connected to the limiting plate, which can be implemented using a metal stamping part or an injection molded part. Its end extends into the second sliding groove, and it drives the limiting post to move by sliding, thereby controlling the working state of the limiting mechanism.

[0054] Specifically, the opening direction of the second sliding groove is consistent with the adjustment direction of the limiting mechanism. When the push plate slides within the second sliding groove, it can drive the limiting post to move along the limiting groove, thereby locking or unlocking the limiting ring. When it is necessary to adjust the unfolding angle of the second hammer handle, the operator slides the push plate along the second sliding groove, causing the limiting post to disengage from the current limiting groove and move to the target position, thus quickly completing the adjustment of the limiting mechanism. This design strictly limits the operating trajectory of the limiting mechanism, avoiding limit failure due to accidental contact or vibration, while ensuring the fitting accuracy between the push plate and the protective shell.

[0055] This solution achieves linear sliding adjustment of the limit column through the cooperation of the second sliding groove and the push plate. The operation can be completed without tools, which significantly improves the adjustment efficiency and reliability of the limit mechanism.

[0056] Through the above technical solution, this application solves the problems of difficult adjustment and easy loosening of the existing geological hammer limiting mechanism. By constraining the movement trajectory of the push plate through the second sliding groove, it ensures that the limiting column is accurately embedded in the limiting groove, which enhances the stability of the limiting mechanism. At the same time, it simplifies the operation steps and enables the geological hammer to quickly adapt to the needs of different operation scenarios.
