Description

Technical Field

[0001] This utility model relates to geological exploration, and in particular to a geological exploration hammer. Background Technology

[0002] Geological exploration is the investigation and research activity that uses various means and methods to explore and detect geology, determine suitable bearing strata, determine the foundation type based on the bearing capacity of the bearing strata, and calculate foundation parameters. It involves investigating and researching the geological conditions of a specific area, including rocks, strata, structures, minerals, hydrology, and geomorphology, to ascertain the quality and quantity of minerals, as well as the technical conditions for mining and utilization, and to provide the necessary mineral reserves and geological data for mine construction and design.

[0003] A geological exploration hammer is one of the basic tools in geological work, made of high-quality steel. Its design varies depending on the rock properties of the work area. When using it, the square end is generally used to strike the rock to break it into pieces; the pointed or flat wedge-shaped end is used to strike along the rock strata to peel off rock layers, which is helpful for finding fossils and sampling; it is also used to prepare rock and ore specimens, making them standardized and easy to package.

[0004] When the weight of a geological exploration hammer remains constant, the closer the center of gravity is to the hammer head, the greater the striking force; the closer the center of gravity is to the hammer handle, the easier it is to operate and the better its operability. However, geological exploration hammers in the current technology are generally one-piece, and their center of gravity is difficult to adjust, making it difficult to quickly adapt to different needs under different geological conditions.

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.

[0033] Example 1: This example aims to propose a geological exploration hammer.

[0034] according to Figures 1-6 As shown, it includes a hammer handle 1, an exchange chamber, a locking element, and a counterweight adjustment mechanism.

[0035] The hammer handle 1 extends in the vertical direction, and the hammer head 2 is fixedly connected to the upper part of the hammer handle 1.

[0036] The exchange chamber includes a first exchange chamber 7 and a second exchange chamber 13. The first exchange chamber 7 is located inside the hammer head 2, and the second exchange chamber 13 is located inside the hammer handle 1. A connecting chamber 14 is provided inside the upper end of the hammer handle 1 to connect the first exchange chamber 7 and the second exchange chamber 13.

[0037] The locking element is detachably connected to the connecting cavity 14. The locking element is adapted to the shape of the inner wall of the connecting cavity 14. The locking element is used to close the second exchange cavity 13. The locking element includes a check plate 9. A slot communicating with the connecting cavity 14 is opened on the upper part of the outer side of the hammer handle 1. The check plate 9 is inserted into the slot. The check plate 9 is adapted to the shape of the inner wall of the connecting cavity 14. A pull ring 10 is fixedly connected to one end of the check plate 9. The pull ring 10 is located outside the hammer handle 1. A limiting baffle that blocks the slot is fixed to the other end of the check plate 9. A baffle is provided at the end of the limiting baffle. The width of the baffle is greater than the width of the slot, which can prevent the check plate 9 from being completely pulled out of the slot.

[0038] The check plate 9 is provided with a first locking member for locking the check plate 9 in the slot. The first locking member includes a locking pin 8. The hammer handle 1 has a socket, and the locking pin 8 is inserted into the socket. The check plate 9 is provided with a threaded connection groove that matches the locking pin 8. The end of the locking pin 8 near the check plate 9 is threadedly connected to the threaded connection groove. When the locking pin 8 locks the check plate 9 in the slot, the check plate 9 completely seals the connecting cavity 14, and both the first exchange cavity 7 and the second exchange cavity 13 are in a sealed state.

[0039] The counterweight adjustment mechanism is slidably and sealed within the second exchange chamber 13. The counterweight adjustment mechanism includes a sealing sleeve 4, which is slidably and sealed within the second exchange chamber 13. The sealing sleeve 4 can slide up and down within the second exchange chamber 13. The shape of the sealing sleeve 4 is adapted to the inner wall of the second exchange chamber 13. The top of the sealing sleeve 4 and the bottom of the check plate 9 form a storage cavity within the second exchange chamber 13. The storage cavity is filled with counterweight material. In this embodiment, the counterweight material can be tungsten steel balls. The position of the counterweight material is distributed by sliding the sealing sleeve 4 up and down, and the counterweight material is sent from the second exchange chamber 13 into the first exchange chamber 7, thereby changing the center of gravity position.

[0040] The sealing sleeve 4 is provided with an adjusting component to adjust the vertical position of the sealing sleeve 4 in the second exchange chamber 13. The adjusting component includes a connecting rod 6, a strip-shaped opening 11, and a lever 12. The strip-shaped opening 11 is opened on the outer side of the hammer handle 1. The connecting rod 6 is fixedly connected to the sealing sleeve 4. The end of the connecting rod 6 away from the sealing sleeve 4 passes through the strip-shaped opening 11. The end of the connecting rod 6 away from the sealing sleeve 4 is fixedly connected to the lever 12. The lever 12 is located outside the hammer handle 1. The length of the strip-shaped opening 11 is equal to that of the sealing sleeve 4, and the bottom of the strip-shaped opening 11 is flush with the bottom of the second exchange chamber 13.

[0041] The sealing sleeve 4 is provided with a second locking element for locking the sealing sleeve 4 in the second exchange chamber 13. The second locking element includes a locking bolt and a threaded locking hole 15. The threaded locking holes 15 are arranged in a vertically spaced array on the sealing sleeve 4. The lower part of the outer side of the hammer handle 1 is provided with a locking socket. A locking bolt is inserted into the locking socket. The locking bolt is threadedly adapted to the threaded locking hole 15. The end of the locking bolt near the sealing sleeve 4 is threadedly connected to the adjacent threaded locking hole 15.

[0042] The lower part of the hammer handle 1 is fixedly connected to a grip end, which includes a handle 5 and a handle sleeve 3. The handle 5 is fixedly connected to the lower end of the hammer handle 1, and the handle sleeve 3 is fixedly fitted on the outside of the handle 5.

[0043] Working principle: When hard rock needs to be crushed and a high hammering force is required, turn the locking bolt to release the locking of the sealing sleeve 4 in the second exchange chamber 13, push the lever 12 to move upward, and at the same time the lever 12 moves, it drives the sealing sleeve 4 to move upward through the connecting rod 6. At the same time, turn the locking pin 8 to release the locking of the check plate 9 in the slot and pull the check plate 9 to make the second exchange chamber 13 connected to the first exchange chamber 7, so that the filling material moves from the second exchange chamber 13 to the first exchange chamber 7. Then, reset the sealing sleeve 4 and the check plate 9 and lock them again. At this time, the center of gravity moves upward, which increases the mass of the hammer head 2, increases the inertia during hammering, and increases the kinetic energy and hammering force.

[0044] When it is necessary to strike soft rock or perform fine operations, turn the locking bolt to release the sealing sleeve 4 from the lock in the second exchange chamber 13, turn the locking pin 8 to release the check plate 9 from the lock in the slot, and pull the check plate 9 to connect the second exchange chamber 13 with the first exchange chamber 7. Under the action of gravity, the filling material moves from the first exchange chamber 7 to the second exchange chamber 13. Then, reset the sealing sleeve 4 and the check plate 9 and lock them again. At this time, the center of gravity moves downward, the mass of the hammer handle 1 increases, the operating torque decreases, the kinetic energy and striking force are reduced, and the operability is improved.

[0045] Therefore, dynamic center of gravity adjustment can be achieved by distributing and adjusting the gravity between the hammer head 2 and the hammer handle 1, thus enabling the hammer to be used for multiple purposes and adapting to different needs for striking force and maneuverability in different scenarios.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
