Description

Technical Field

[0001] The invention relates to the technical field of mineral sampling, in particular to a bagged ore sampling auxiliary device. Background Art

[0002] Bag copper concentrate sampling refers to the process of collecting samples of copper concentrate stored and transported in bagged form. This process is crucial in the trade, quality control and pre-smelting preparation of copper concentrate, and is directly related to the accuracy of subsequent analysis and smelting results.

[0003] At present, some units use hand drills to connect sampling rods for sampling. The rotation of the sampling rod generates heat, which affects the accuracy of material moisture determination. The sampling points of manual sampling rods are relatively random, and it is difficult to achieve a scientific and reasonable distribution of the sampling points, and the sample is not representative. When sampling, one person needs to hold the sampling rod by hand, and the other person uses a hammer to hit the sampling rod. During the sampling process, in order to prevent the sampler holding the sampling rod from being hit, the hitter often dares not to exert force, which greatly reduces work efficiency and is very likely to cause impact injuries, posing certain safety hazards. After using a hammer to hit the sampling rod for sampling many times, the sampling rod head is prone to cracking and the rod body is prone to bending, resulting in excessive wear of the rod tool. Summary of the invention

[0025] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0026] Reference Figure 1-3 As shown, an auxiliary device for sampling bagged ore comprises a front end fixing frame 1, a movable groove is provided on the outer surface of the front end fixing frame 1, an iron shoe 101 is fixedly installed on the bottom end of the front end fixing frame 1, a rear end fixing frame 2 is provided on the top of the front end fixing frame 1, two groups of fixed clamping plates 201 are fixedly installed on the bottom end of the rear end fixing frame 2, a drill seat 3 is provided on the top of the rear end fixing frame 2, a fork tine 4 is provided through the top of the drill seat 3, one end of the fork tine 4 can be connected to a forklift, and the other end of the fork tine 4 is fixedly installed on the outer surface of the bottom end of the iron shoe 101 by two groups of fixing bolts, a movable spring 202 is sleeved on the outer surface of the fork tine 4, a slider 203 is fixedly installed on one end of the movable spring 202, and the slider 203 is slidably installed on the outer surface of the fork tine 4, a movable rod 204 and a lock pin 205 are respectively fixedly installed on the outer surface of the slider 203, and a drill rod 5 is provided inside the rear end fixing frame 2.

[0027] In this solution, the movable connection of the drill seat 3 at the top of the rear end fixing frame 2 provides a mounting platform for the fork tine 4. The elastic characteristics of the movable spring 202 installed on the outer surface of the fork tine 4 enable the rapid disassembly and assembly of the drill rod 5 to be achieved through the sliding installation of the slider 203 on the outer surface of the fork tine 4 and the fixed installation of the movable rod 204 and the locking pin 205.

[0028] Reference Figures 4 to 6 As shown, a limit plate 6 is arranged inside the drill rod 5, and the limit plate 6 is movably installed inside the drill rod 5. A fixed block 601 is fixedly installed on the top of the limit plate 6, and two groups of slide grooves 602 are provided on the outer surface of the fixed block 601. A limit spring 603 is movably installed inside the fixed block 601, and a movable block 604 is movably installed on one end of the limit spring 603. A limit block 605 is arranged on the rear side of the movable block 604. A plurality of groups of limit slots 501 are provided on the outer surface of the drill rod 5, and the limit blocks 605 are clamped in the inside of the limit slots 501.

[0029] Combined with Figure 4 , 5 As shown, one end of the drill rod 5 is fixedly installed with a mounting seat 502, and two groups of card blocks 503 are arranged on the top of the mounting seat 502. There is a bayonet 505 between the card block 503 and the mounting seat 502, and a slot 504 is opened at the bottom end of at least one group of card blocks 503. When the drill rod 5 needs to be installed, the lock pin 205 is driven downward to make way by pressing the movable rod 204, and the drill rod 5 is inserted into the through hole of the front end fixing frame 1, and then placed between the two groups of fixed card plates 201 through the mounting seat 502, wherein the cross-sectional shape of the fixed card plate 201 is L-shaped, which includes a lower card 2011 and a connecting plate 2012, the lower card 2011 is parallel to the bottom surface of the rear end fixing frame 2, and the connecting plate 2012 is used to connect the lower card 2011 and the bottom surface of the rear end fixing frame 2, and the two fixed card plates 2 01 is relatively arranged, and a slot 2013 arranged parallel to the lower card 2011 is also provided on the connecting plate 2012, and the opening directions of the slots on the two sets of fixed card plates 201 are opposite. At this time, the drill rod 5 is rotated to make the lower card 2011 pass through the bayonet 505, and the block 503 also passes through the slot 2013, so that the drill rod 5 and the fixed card plate 201 are engaged with each other, and the drill rod 5 is limited in the up and down directions. Then the movable rod 204 is released, and the restoring force of the movable spring 202 drives the locking pin 205 upward to ensure that the drill rod 5 is positioned in the horizontal direction. Then the locking pin 205 is inserted into the slot 504 to lock the drill rod 5. The disassembly of the drill rod 5 is opposite to the installation. You only need to press down the movable rod 204, and then rotate the drill rod 5 to remove it. Through such a structural design, the rapid disassembly and assembly of the drill rod 5 can be achieved.

[0030] In the present solution, a limit plate 6 is provided inside the drill rod 5 to improve the accuracy and stability of sampling. The limit plate 6 cooperates with the fixed block 601, the slide groove 602, the limit spring 603, the movable block 604 and the limit block 605, so that the operator can flexibly adjust the sampling depth of the drill rod 5 as needed. When the limit block 605 is accurately engaged in the limit slot 501 on the outer surface of the drill rod 5, the drill rod 5 is ensured to be firmly locked during the sampling process, effectively avoiding shaking or falling off due to external force, thereby realizing precise control of the sampling process.

[0031] The working principle of the present invention is as follows: one end of the fork tine 4 is connected to a forklift and the forklift is used for sampling. Through the combination of the front fixing frame 1 and the rear fixing frame 2, and the movable connection of the drill seat 3, the fork tine 4 can be fixedly installed in the drill seat 3 through the iron shoe 101. Through the sliding of the slider 203 on the fork tine 4, and the fixing effect of the movable rod 204 and the locking pin 205, the disassembly and assembly process of the drill rod 5 is simplified, and the operating efficiency is improved. The inside of the drill rod 5 is also provided with a limit plate 6 for adjusting the sampling depth, which cooperates with the slide groove 602, the limit spring 603, and the movable block 604 on the fixed block 601. As well as the limit block 605, when it is necessary to adjust the sampling depth of the drill rod 5, the movable block 604 can be operated to slide in the slide groove 602 and compress or release the limit spring 603, thereby driving the limit block 605 to engage in or disengage from different limit slots 501 on the outer surface of the drill rod 5, thereby realizing the depth adjustment of the drill rod 5 during the sampling process, and the limit block 605 is engaged with the limit slot 501 to ensure that the drill rod 5 is firmly locked during sampling, effectively preventing the sampling depth from changing due to external force, ensuring the accuracy of sampling, and meeting the needs of the staff.
