Description

Technical Field

[0001] This utility model relates to the field of mining tools, specifically a multi-functional mining tool. Background Technology

[0002] In mining operations, not only are large mining equipment such as self-propelled crushers, transfer machines, and dump machines needed, but also small auxiliary tools such as mining hammers and chisels are required for sampling, analysis, or observation of ore materials. These tools are used on-site to allow personnel to temporarily sample, analyze, observe, and make judgments about the ore materials. Mining tools is a broad term that includes large mining machinery, ore loading loader conveyors, and small auxiliary tools used in mining operations.

[0003] In on-site mining, when temporarily crushing and sampling ore, the mining hammer is an indispensable small auxiliary tool. Existing mining hammers have the following shortcomings: 1. The mining hammer consists of a handle and a hammerhead. One side of the hammerhead is flat, and the other side is a conical chisel. During crushing observation, further crushing is sometimes necessary for observation, or the use of an arc-shaped part to impact and observe the concave shape to determine hardness. The existing simple hammerhead is insufficient to meet application requirements and has poor applicability. 2. There is a lack of a protection mechanism for the conical structure when not in use, posing a risk of scratching and injuring personnel during transport, resulting in poor carrying safety. Therefore, this application proposes a multi-functional mining tool to solve the above-mentioned problems. Utility Model Content

[0028] 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.

[0029] like Figures 1 to 4 As shown in this embodiment, a multi-functional mining tool includes:

[0030] The U-shaped support 2 has an arc-shaped protective cover 202 with an opening on the left side fixedly connected to its right side and top;

[0031] Stainless steel support shaft 201 is rotatably fitted between the front and rear sides of U-shaped support 2;

[0032] The cross hammer body 1 is fixedly sleeved on the stainless steel support shaft 201. Its left side is the flat hammer part 101, its right side is the mining cone chisel part 103, its bottom is the sag part 102, and its top is the multi-pointed cone crushing part 104.

[0033] The pull-to-unlock rotary locking assembly is fixedly installed on the front side of the U-shaped support 2 and fixedly sleeved on the outside of the stainless steel support shaft 201. The pull-to-unlock rotary locking assembly is used to unlock the stainless steel support shaft 201 by conveniently pulling down, and to lock it after rotating the cross hammer body 1 to drive the stainless steel support shaft 201 to rotate. Locking the stainless steel support shaft 201 locks the adjusted cross hammer body 1. The cross hammer body 1 has a flat hammer part 101, a mining cone chisel part 103, an arc sag part 102, and a multi-pointed cone crushing part 104 on its four sides, which provide a variety of different forms of operation. When it is necessary to temporarily collect samples or crush and analyze ore in mining operations, personnel can flexibly select different application methods.

[0034] The threaded telescopic adjustable handle assembly is fixedly connected to the bottom of the U-shaped support 2; the threaded telescopic adjustable handle assembly is used for personnel to hold and to flexibly adjust the holding application length according to different personnel application needs;

[0035] In this embodiment, the mining cone chisel 103, the sag section 102, and the multi-pointed cone crushing section 104 are all located inside the arc-shaped protective cover 202. The arc-shaped protective cover 202 is used to shield and protect the two pointed cone structures of the cross hammer body 1 when not in use, allowing personnel to adjust them by rotating the cover. This reduces the possibility of the two pointed cone structures being exposed and accidentally scratching or injuring personnel during transport, thus improving the safety of carrying and application. The U-shaped support 2 has round through holes on both the front and rear sides. A first bearing is fixedly fitted inside the round through holes. The inner ring of the first bearing is fixedly fitted to the outer side of the stainless steel support shaft 201, which serves to rotate and install the stainless steel support shaft 201.

[0036] Furthermore, such as Figure 1 and 3 As shown, the pull-to-unlock rotary locking assembly includes a fixing ring 3, a fixing sleeve 302, a T-shaped locking block 303, two vertical guide rods 304, two springs 305, and a pull ring 306. The fixing ring 3 is welded and sleeved on the outside of the stainless steel support shaft 201. The top, bottom, left, and right sides of the fixing ring 3 are provided with slots 301, and the four slots 301 are set one-to-one with the four sides of the cross hammer body 1. The fixing sleeve 302 is fixedly connected to the front side of the U-shaped support 2. The bottom of the fixing sleeve 302 is set as a sealing structure. The T-shaped locking block 306... 03 Sliding sleeve is installed inside the fixed sleeve 302. The top of the T-shaped block 303 is movably installed in the lower slot 301 and is set as an arc structure. The two vertical guide rods 304 are fixedly connected to the bottom of the T-shaped block 303. The bottom ends of the two vertical guide rods 304 slide out to the bottom of the fixed sleeve 302 and are fixedly connected to the top of the pull ring 306. The two springs 305 are fixedly connected between the bottom of the T-shaped block 303 and the bottom inner wall of the fixed sleeve 302. The springs 305 are movably sleeved on the corresponding vertical guide rods 304.

[0037] In this embodiment, two vertical guide holes are provided on the bottom inner wall of the fixing sleeve 302, which are respectively slidably fitted onto the outer side of the corresponding vertical guide rod 304, so as to allow the vertical guide rod 304 to pass through and guide its vertical sliding.

[0038] In this embodiment, the fixed ring 3, four slots 301, fixed sleeve 302, T-shaped locking block 303, two vertical guide rods 304, two springs 305, and pull ring 306 work together. Pulling the pull ring 306 downward causes it to slide the T-shaped locking block 303 downward within the fixed sleeve 302 via the two vertical guide rods 304, compressing the two springs 305. The T-shaped locking block 303 then separates downward from the slots 301 below, releasing the lock on the fixed ring 3 and consequently releasing the lock on the stainless steel support shaft 201. At this point, the operator can rotate the cross hammer body 1. The cross hammer body 1 rotates the fixed ring 3 via the stainless steel support shaft 201. After the side of the cross hammer body 1 that needs to be used is suspended to the left, the pull ring is released. The tension of 306 causes the two springs 305, which are in a compressed state, to move the T-shaped locking block 303 upward and lock it into the slot 301 that has rotated to the lower part, thereby locking the fixing ring 3 and the stainless steel support shaft 201 and the cross hammer body 1. This allows for easy unlocking of the stainless steel support shaft 201 by pulling it down and locking after rotating and adjusting the cross hammer body 1. The cross hammer body 1 has a variety of different forms of support, namely the flat hammer part 101, the mining cone chisel part 103, the sag part 102, and the multi-pointed cone crushing part 104 on its four sides. This allows for flexible selection and application when temporary sampling or crushing analysis of ore is required in mining operations, improving the flexibility and applicability of use.

[0039] Furthermore, such as Figure 3 and 4 As shown, the threaded telescopic adjustable handle assembly includes an inner rod 401, an outer tube 4, and a T-shaped screw 402. The inner rod 401 is welded to the bottom of the U-shaped support 2. The outer tube 4 is slidably sleeved on the inner rod 401. The bottom end of the outer tube 4 is set as a sealing structure. The T-shaped screw 402 is rotatably embedded in the bottom end of the outer tube 4. The inner rod 401 is threadedly sleeved on the T-shaped screw 402.

[0040] In this embodiment, a limiting groove is provided on the right side of the inner rod 401, and a limiting block that is slidably connected to the limiting groove is fixedly connected to the inner wall of the right side of the outer tube 4, which serves to vertically limit and prevent the outer tube 4 from detaching; a threaded groove is provided at the bottom end of the inner rod 401 for threaded connection with the T-shaped screw 402, and the threaded connection between the T-shaped screw 402 and the threaded groove facilitates the upward and downward displacement when the T-shaped screw 402 rotates; an anti-slip rubber sleeve is bonded to the outer side of the outer tube 4, which provides anti-slip and shock absorption when personnel use their hands to knock and strike temporary mining samples; a through hole is provided at the bottom end of the outer tube 4, and a second bearing is fixedly fitted inside the through hole. The inner ring of the second bearing is fixedly connected to the outer side of the T-shaped screw 402, which serves to rotate and install the T-shaped screw 402.

[0041] In this embodiment, the inner rod 401, outer tube 4, and T-shaped screw 402 work together. The outer tube 4 is provided for handheld operation. When the length of the handheld part needs to be adjusted, the person rotates the T-shaped screw 402 so that it rotates in the threaded groove on the inner rod 401 and moves downward or upward. The T-shaped screw 402 drives the outer tube 4 to slide downward or move upward on the inner rod 401, so that the length of the inner rod 401 extending outside the outer tube 4 changes. This changes the total length formed by the outer tube 4 and the inner rod 401, achieving the effect of flexibly adjusting the handheld application length according to the different application needs of different personnel, further improving applicability and usage flexibility.

[0042] It should be noted that the fixing ring 3, fixing sleeve 302, T-shaped clip 303, inner rod 401, outer tube 4 and T-shaped screw 402 are all preferably made of stainless steel. The outer thread gap of the T-shaped screw 402 is a high wear-resistant load-bearing specification of 1-2mm. The stainless steel material has the advantages of high hardness, high wear resistance and good maintenance-free effect, which ensures long-term connection and drive support stability.

[0043] The usage method of this embodiment is as follows: When using this multi-functional mining tool, the operator holds the anti-slip rubber sleeve on the outside of the outer tube 4 and operates the cross hammer body 1 to strike the ore to open for sampling. The anti-slip rubber sleeve provides anti-slip and shock absorption when the operator holds the hammer to temporarily mine and sample. When the mining cone chisel 103 is needed for cone impact crushing, the pull ring 306 is pulled down to make it slide downward through the two vertical guide rods 304, causing the T-shaped locking block 303 to slide downward within the fixed sleeve 302, compressing the two springs 305. The T-shaped locking block 303 then slides downward into the slot below. 301 separates, releasing the lock on the fixed ring 3, and consequently releasing the lock on the stainless steel support shaft 201. At this point, the operator can rotate the cross hammer body 1. The cross hammer body 1, through the stainless steel support shaft 201, drives the fixed ring 3 to rotate. When the cross hammer body 1 drives the mining cone chisel part 103 to the left position, the tension on the pull ring 306 is released. The two springs 305, now compressed, drive the T-shaped locking block 303 upwards and into the lowered locking groove 301, thus locking the fixed ring 3, and consequently, locking the stainless steel support shaft 201 and... With the cross hammer body 1 locked, personnel can then use the mining cone chisel part 103 to impact and crush the ore. When it is necessary to use the sag part 102 to observe the concave shape and determine the hardness, the pull ring 306 can be pulled down again to unlock it. Then, the cross hammer body 1 can be rotated again to rotate the sag part 102 to the left, and the pull ring 306 can be released to lock it. For further impact crushing to effectively observe the ore properties, the multi-pointed cone crushing part 104 can be rotated to the left in the same manner. The stainless steel support shaft 201 can be easily unlocked by pulling down, and locked after rotating and adjusting the cross hammer body 1. The four sides of the cross hammer body 1 provide a variety of different forms, namely the flat hammer part 101, the mining cone chisel part 103, the arc sag part 102, and the multi-pointed cone crushing part 104. In mining operations, when it is necessary to temporarily collect and sample or crush and analyze ore, it is convenient for personnel to flexibly select the application by rotating, which can better meet the various application needs in mining sampling and improve the flexibility and applicability of use.

[0044] After use, personnel can rotate the mining cone chisel 103, the sag section 102, and the multi-pointed cone crushing section 104 into the arc-shaped protective cover 202 using the same rotation method described above, leaving only the safe flat hammer section 101 exposed. This achieves the effect of conveniently storing and protecting the two pointed cone structures of the cross hammer body 1 in one piece by simply rotating it when not in use, reducing the possibility of accidental scratches and injuries to personnel caused by the two pointed cone structures being exposed during carrying, and improving the safety of carrying and application.

[0045] When the length of the handheld part needs to be adjusted during use, the user rotates the T-shaped screw 402 so that it rotates within the threaded groove on the inner rod 401 and moves downward or upward. The T-shaped screw 402 drives the outer tube 4 to slide downward or move upward on the inner rod 401, causing the length of the inner rod 401 extending outside the outer tube 4 to change. This, in turn, changes the total length formed by the outer tube 4 and the inner rod 401, achieving the effect of flexibly adjusting the handheld application length according to the application needs of different users, further improving applicability and usage flexibility.

[0046] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
