Description

Technical Field

[0001] The utility model relates to the technical field of mine geological sampling, in particular to a multifunctional breaking hammer used for mine geological sampling. Background Art

[0002] In the early stages of mining, a 3-5-person inspection team is required to take geological samples to determine whether the geology is worth mining. Since the mine roads are rugged and there is no electricity coverage, some large crushing equipment is difficult to carry and has low practical value. The inspection team members generally carry a breaker hammer with them to crush and sample the mine geology.

[0003] Crank breakers allow samplers to exert greater force, keeping their hands further away from objects when striking them, making them less likely to collide with them. This improves safety and has led to their widespread use. Traditional crank breakers, however, are limited by the directional nature of the hand grip and can only be used to hammer or chisel at one end of the hammer. This limited functionality requires two crank breakers with different functions to accommodate varying geological conditions, increasing the burden on personnel. Utility Model Content

[0004] The utility model provides a breaker hammer for mining geological sampling, which aims to solve the problem that the breaker hammer can only use the crushing head at one end of the hammer body for crushing in the best grip posture.

[0005] The technical solution of this utility model is as follows:

[0006] A breaker hammer for sampling in mining geology, comprising a curved hammer handle and a hammer body arranged at one end of the curved hammer handle, the curved hammer handle comprising a grip and an axis column that passes through the hammer body and is slidably connected to the hammer body, a connecting block is fixed between the grip and the axis column; the axis column is connected to a limiting ring after passing through the hammer body, a connecting rod is provided between the limiting ring and the corresponding surface of the hammer body; a first spring is provided between the limiting ring and the connecting rod; a limiting hole is provided on the connecting block, and the limiting holes are symmetrically arranged on both sides of the axis column; a second spring is provided between the connecting rod and the hammer body, and a limiting rod that passes through the second spring and corresponds to the limiting hole on the connecting block is fixed on the connecting rod, and the limiting rod is connected to the connecting block through the limiting hole after passing through the hammer body; a first crushing head and a second crushing head are provided at both ends of the hammer body, respectively.

[0007] Furthermore, a threaded groove is provided at the top end of the shaft column for threaded connection with the limiting ring.

[0008] Furthermore, the first crushing head is a flat hammer head, and the second crushing head is a quadrangular pyramid chisel head with the tip facing outward.

[0009] Furthermore, a plurality of notches are evenly distributed on the circumference of the outer surface of the limiting ring.

[0010] Furthermore, a finger groove is provided on the curved hammer handle, and a rubber package is provided on the surface of the curved hammer handle.

[0011] Compared with the prior art, the utility model has the following positive effects: through the cooperation of the limiting ring, the first spring, the connecting rod, the second spring, the limiting rod and the limiting hole on the connecting block, the sampling personnel can easily realize the conversion of the hammer crushing head, so that the sampling personnel can select a suitable crushing head for the mine geology with different hardness when crushing and sampling the mine geology, and the hands can always maintain the best grip posture. The personnel do not need to carry two crank breakers with different functions, which reduces the burden on the personnel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0018] like Figures 1-4The breaker hammer of embodiment 1 is a kind of breaker hammer for mining geology, comprising a curved hammer handle 1 and a hammer body 4 arranged at one end of the curved hammer handle 1, the curved hammer handle 1 comprising a grip and a shaft column 3 that passes through the hammer body 4 and is slidably connected to the hammer body 4, a connecting block 2 is fixed between the grip and the shaft column 3; the connecting block 2 is provided with a limiting hole, and the limiting holes are symmetrically arranged on both sides of the shaft column 3; the top of the shaft column 3 is provided with a threaded groove 31, and the shaft column 3 passes through the hammer body 4 and is connected to the limiting ring 5 through the threaded groove 31; a connecting rod 6 is provided between the corresponding surfaces of the limiting ring 5 and the hammer body 4; a first spring 51 is provided between the limiting ring 5 and the connecting rod 6; a second spring 8 is provided between the connecting rod 6 and the hammer body 4, and a limiting rod 7 that passes through the second spring 8 and corresponds to the limiting hole on the connecting block 2 is fixed on the connecting rod 6, and the limiting rod 7 passes through the hammer body 4 and is connected to the connecting block 2 through the limiting hole. The hammer body 4 is provided with a first crushing head 41 and a second crushing head 42 at each end. The first crushing head 41 is a flat hammer head, while the second crushing head 42 is a four-sided conical chisel head with the tip facing outward. The switch between the two crushing heads can cope with complex mining geological conditions and is suitable for crushing and sampling mining geological materials of different hardness.

[0019] The outer surface of the limiting ring 5 is evenly distributed with a plurality of notches 52 around its circumference, which are used to cooperate with the metal rod to disassemble and assemble the limiting ring 5.

[0020] The gripping end of the curved hammer handle 1 is provided with a finger groove 11 , and the surface of the curved hammer handle 1 is wrapped with rubber, which can increase the friction between the user's fingers and the curved hammer handle 1 to prevent slipping and improve grip comfort.

[0021] The curved hammer handle 1 is provided with a through hole 12 at one end away from the hammer body 4 for hanging and storing to prevent loss. In addition, it can also be used to fix a rope, one end of which is tied to the user's wrist to prevent it from slipping out of the hand and being lost during use.

[0022] The specific method of using the breaker hammer of the present invention is as follows: pull the connecting rod 6 away from the hammer body 4, thereby driving the limiting rod 7 to disengage from the limiting hole, so that the hammer body 4 is separated from the connecting block 2. At this time, the first spring 51 is in a compressed state and the second spring 8 is in a tensile state. The user manually twists the crushing head to rotate it 180 degrees, and then releases the connecting rod 6. Under the action of the first spring 51 and the second spring 8, the connecting rod 6 gradually approaches the hammer body 4, driving the limiting rod 7 to pass through the hammer body 4 and the connecting block 2 in sequence. The limiting rod 7 cooperates with the limiting hole on the connecting block 2 to limit the hammer body 4 after the direction is changed, thereby completing the conversion of the crushing head. In this way, when the sampling personnel use the breaker hammer of the utility model to crush and sample the mine geology, they can select the appropriate crushing head for crushing and sampling according to the mine geology of different hardness, and ensure that their hands always maintain the best grip posture. If the hardness is high, the second crushing head 42 can be selected to crush it. If the hardness is low, the first crushing head 41 can be selected to crush it more thoroughly. Its functions are more diversified, and the sampling personnel do not need to carry two crank breakers with different functions, which reduces the burden.

[0023] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
