Description

Technical Field

[0001] The present invention relates to the technical field of rock sampling, and particularly to a handheld portable field rock sampling device. Background Art

[0002] Field rock sampling refers to field operations carried out in fields such as geological exploration, mineral resource survey, geotechnical engineering, and archaeological research to obtain rock samples. The purpose of sampling is for geological research: observing and studying the structure, texture, mineral composition and their symbiotic combination of rocks, studying the metamorphism and alteration phenomena of minerals, determining the names of rocks and minerals, comparing strata and rocks, and through sampling analysis, understanding the types, contents and distribution characteristics of minerals in rocks, providing a basis for the development and utilization of mineral resources, evaluating the engineering properties of rocks such as strength and stability, providing important parameters for engineering design and construction, and through rock sampling, understanding information such as the environment and geological background of ancient human activities, providing clues for archaeological research.

[0003] According to the physical properties of rocks such as hardness, brittleness, and toughness, appropriate sampling methods are selected. Commonly used sampling methods include manual hammering method, mechanical cutting method, drilling sampling method, etc., and commonly used sampling tools include geological hammers, geological shovels, handheld drills, sampling tubes, etc. These tools should have sufficient strength and hardness to meet the sampling requirements of different rocks.

[0004] Currently, the commonly used sampling devices are still geological hammers and geological shovels. In actual operation, it is mostly necessary to manually break the rock into small pieces and then put them into a storage container for storage. This process is not only time-consuming and laborious, but also has low efficiency. Especially in the case of needing to collect a large number of samples or the samples have high hardness, the difficulty and time consumption of manually breaking the rock will increase significantly. Summary of the Invention

[0005] In view of the problem that the existing devices mostly need to manually break the rock into small pieces and then put them into a storage container for storage in actual operation, this process is not only time-consuming and laborious, but also has low efficiency.

[0019] Advantages of the present invention:

[0020] 1.

Compared with manually using a geological hammer to break the rock, the automated device can complete more sampling work in a shorter time, and at the same time, it can greatly reduce the labor intensity of the operator and lower the labor cost. The operator only needs to simply operate the device to complete the sampling work, without the need for heavy physical labor like using a geological hammer, which helps to protect the physical health of the operator and improve work efficiency.

[0021] 2. In the present invention, the two rotating crushing rollers can perform pre-crushing on the sampled rock blocks, facilitating subsequent sample processing and analysis, thus greatly improving the efficiency of the sampling work, and also enabling preliminary analysis and detection directly on-site, which is convenient for the operator to quickly understand the properties and components of the rock.

Moreover, when only crushing is required according to the demand, the operating pull rod can be pushed to move the first gear away from between the second gear and the third gear, thereby interrupting the power transmission and making the impact head no longer move back and forth. The two rotating crushing rollers can be operated independently for crushing, thus improving the practicability of the device.

In the present invention, by providing multiple collecting drawers in the storage cavity, rock samples from different sources, of different types or with different properties can be classified and stored, avoiding sample confusion and cross-contamination. At the same time, classified storage helps with sample tracking and data processing during subsequent laboratory analysis, improving work efficiency and accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the spirit of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0045] Embodiment 1

[0046] Referring to Figure 1-13 , for the first embodiment of the present invention, a handheld portable field rock sampling device is provided. This handheld portable field rock sampling device includes a device body 1, and further includes a crushing chamber 11 opened at the top of the inner cavity of the device body 1, an installation chamber 12 opened on one side of the top of the inner cavity of the device body 1 away from the crushing chamber 11, a storage chamber 13 opened at the bottom of the inner cavity of the device body 1 and located below the crushing chamber 11, a crushing component 2 arranged in the crushing chamber 11, a gravel component 3 arranged in the installation chamber 12, and a collection component 4 arranged in the storage chamber 13. A grip rod is installed on one side of the bottom of the device body 1, and auxiliary handles are provided on the top and one side of the device body 1 to facilitate the gripping and use of the device body 1;

[0047] The crushing component 2 includes rotating shafts 21 rotatably connected to both ends of the two sides of the inner cavity of the crushing chamber 11, and one end of the rotating shaft 21 extends into the inner cavity of the installation chamber 12. A crushing roller 23 is fixedly sleeved on the surface of the installation chamber 12 to play a crushing role. A motor 22 is fixedly installed at one end of one side of the inner cavity of the installation chamber 12, and the output end of the motor 22 is connected to one end of a group of rotating shafts 21 located in the inner cavity of the installation chamber 12. A synchronous gear 24 is fixedly sleeved on one end of the surface of the rotating shaft 21, and the two groups of synchronous gears 24 are located in the inner cavity of the crushing chamber 11 and mesh with each other. A feed inlet 25 is installed on one side of the top of the device body 1, and the feed inlet 25 communicates with the inner cavity of the crushing chamber 11 and is located above the two crushing rollers 23. A cover plate 26 is hinged to one end of the top of the feed inlet 25. Through the setting of the cover plate 26, when the two crushing rollers 23 rotate to crush the rock, the cover plate 26 can be covered on the top of the feed inlet 25, thereby avoiding the splashing of debris when crushing the rock blocks and preventing harm to the operator.

[0048] The crushing component 2 further includes a blanking chute opening 27 opened at the bottom of the inner cavity of the crushing chamber 11, and the blanking chute opening 27 communicates with the inner cavity of the storage chamber 13. The blanking chute opening 27 is arranged in an inverted cone shape to facilitate the centralized guiding and falling operation of the crushed qualified rock blocks.

[0049] During use, first start the motor 22 to drive a set of rotating shafts 21 to rotate. Then, through the synchronous gears 24 on the surfaces of the two sets of rotating shafts 21 meshing with each other, the two sets of rotating shafts 21 can be driven to rotate synchronously. Then, the two crushing rollers 23 are rotated. At this time, the collected rock blocks can be put into the crushing chamber 11 through the feed port 25, and then the cover plate 26 is covered. The two rotating crushing rollers 23 can crush the rock blocks.

[0050] Embodiment 2

[0051] Refer to Figure 1-13 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the crushing component 3 includes an impact component 31 arranged on one side of the device body 1, a reciprocating component 32 arranged in the inner cavity of the installation cavity 12, and a driving component 33 arranged on the reciprocating component 32.

[0052] The impact component 31 includes a limit sleeve 313 fixedly installed on one side of the device body 1, an impact rod 311 slidably connected in the inner cavity of the limit sleeve 313. One end of the impact rod 311 extends to the outside of the limit sleeve 313 and is provided with an impact head 312. And one end of the limit sleeve 313 away from the impact head 312 extends into the inner cavity of the installation cavity 12. The larger rock blocks can be impacted by the impact head 312 to be broken into smaller ones;

[0053] Three slide rails 314 opened on the surface of the impact rod 311 and close to one side of the limit sleeve 313, and sliders 315 slidably connected to the inner sides of the slide rails 314. And one end of the slider 315 away from the slide rail 314 is connected to the inner cavity of the limit sleeve 313. By the slider 315 being slidably connected in the slide rail 314, the impact rod 311 is restricted to move back and forth only in the limit sleeve 313 and cannot rotate, which is convenient for more stable impact operation.

[0054] The reciprocating component 32 includes a mounting seat 321 fixedly installed at the top inside the mounting cavity 12, a mounting cylinder 322 fixedly installed on one side of the mounting seat 321, and the mounting cylinder 322 penetrates through the mounting seat 321. One end of the impact rod 311 located inside the mounting cavity 12 extends into the inner cavity of the mounting cylinder 322, a mounting disc 326 fixedly installed at one end of the impact rod 311 located inside the mounting cylinder 322, two arc-shaped side plates 327 fixedly connected to the edge of the mounting disc 326 away from the impact rod 311, a first rotating rod 323 rotatably connected to the side of the mounting cylinder 322 away from the impact rod 311, one end of the first rotating rod 323 extends into the inner cavity of the mounting cylinder 322, and the other end of the first rotating rod 323 is rotatably connected to one side of the inner cavity of the mounting cavity 12, a rotating column 324 fixedly installed at one end of the first rotating rod 323 located inside the mounting cylinder 322, a double V-shaped notch 325 opened on the surface of the rotating column 324, and a positioning block 328 provided at one end of the arc-shaped side plate 327 close to the rotating column 324, and one end of the positioning block 328 is slidably connected to the inside of the double V-shaped notch 325.

[0055] The driving component 33 includes a second rotating rod 331 fixedly installed at one end of the mounting cylinder 322 away from the impact rod 311, and one end of the second rotating rod 331 is rotatably connected to one side of the inner cavity of the mounting cavity 12, a sleeve 332 rotatably connected to the surface of the second rotating rod 331 close to one end of the rotating shaft 21, a first gear 333 rotatably connected to the surface of the sleeve 332, a third gear 335 fixedly sleeved on the surface of one end of a group of rotating shafts 21 located inside the mounting cavity 12, a second gear 334 fixedly sleeved on the surface of the first rotating rod 323 close to one end of the rotating shaft 21, and a first spring 330 sleeved on the surface of the second rotating rod 331 close to one end of the mounting cylinder 322;

[0056] A U-shaped mounting frame 336 fixedly installed on the top surface of the sleeve 332, a limiting notch 338 opened on the top of the device body 1 away from one side of the feeding port 25, and the limiting notch 338 communicates with the inner cavity of the mounting cavity 12, an L-shaped limiting notch 339 opened on the top of the device body 1 close to one side of the limiting notch 338, and one end of the L-shaped limiting notch 339 communicates with one end of the limiting notch 338, the L-shaped limiting notch 339 communicates with the inner cavity of the mounting cavity 12, and an operating pull rod 337 provided on the top of the U-shaped mounting frame 336, and the top end of the operating pull rod 337 extends to the outside of the device body 1 through the limiting notch 338. Through the setting of the L-shaped limiting notch 339, the operating pull rod 337 can be restricted, and further the first gear 333 on the sleeve 332 can be limited.

[0057] During use, when the motor 22 is started to drive the two rotating shafts 21 to rotate, causing the two crushing rollers 23 to also rotate, the third gear 335 on one of the rotating shafts 21 can be driven to rotate. Since the first gear 333 is located between the second gear 334 and the third gear 335 and meshes with them, the first gear 333 and the second gear 334 can be driven to rotate synchronously. Then, the first rotating rod 323 can be driven to rotate, causing the rotating column 324 in the mounting cylinder 322 to rotate. Then, the positioning block 328 sliding inside the double V-shaped notch 325 moves along the double V-shaped notch 325, thereby pushing the arc-shaped side plate 327 to move back and forth. As a result, the impact rod 311 on the mounting plate 326 also moves back and forth, and finally the impact head 312 on the impact rod 311 also moves back and forth. At this time, the device body 1 can be held to press the impact head 312 against a larger rock block, and then the rock block can be automatically impacted and cut. Then, the sample cut by impact is placed into the feed port 25, and it can be crushed by the two rotating crushing rollers 23.

[0058] When the motor 22 is started and the impact head 312 has completed the impact cutting operation on the larger rock block, the operating pull rod 337 can be pulled to slide in the limit notch 338, causing the operating pull rod 337 to drive the sleeve 332 on the U-shaped mounting frame 336 to move on the surface of the second rotating rod 331. At the same time, the first spring 330 on the surface of the second rotating rod 331 is compressed. Then, when the operating pull rod 337 moves to the end of the limit notch 338 close to the L-shaped limit notch 339, the operating pull rod 337 can be deflected into the L-shaped limit notch 339. Then, the operating pull rod 337 is fixed at one end stuck in the L-shaped limit notch 339 by the resilience of the first spring 330. At the same time, when the sleeve 332 moves, the first gear 333 can be moved away from between the second gear 334 and the third gear 335, thereby interrupting the power transmission and causing the impact head 312 to stop moving back and forth. The two rotating crushing rollers 23 can be operated independently for crushing.

[0059] The remaining structure is the same as that of Embodiment 1.

[0060] Embodiment 3

[0061] Refer to Figure 1-13, which is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the collection component 4 includes a storage component 41 disposed inside the storage cavity 13, and a fixing component 42 disposed at the bottom on one side of the device body 1. The storage component 41 includes six groups of limiting channels 411 installed on one side inside the storage cavity 13, and one end of the limiting channel 411 extends to the outside of the device body 1. A collection drawer 413 is slidably connected inside the limiting channel 411, and one end of the collection drawer 413 extends to the outside of the limiting channel 411. A side cover plate 414 is fixedly installed at the end of the collection drawer 413 located outside the limiting channel 411. A material dropping port 412 is opened at the top of a group of limiting channels 411 and is located below the blanking slot 27. The material dropping port 412 is in communication with the inside of the limiting channel 411. Through the setting of the material dropping port 412 on a group of limiting channels 411, it is convenient to transfer the rock fragments guided by the blanking slot 27 into this group of limiting channels 411, and an operation handle 415 is provided on one side of the side cover plate 414. Through the setting of the operation handle 415, it is convenient to pull out the collection drawer 413 from the limiting channel 411.

[0062] The fixing component 42 includes fixing bins 421 fixedly installed at both ends of the bottom on one side of the device body 1, positioning columns 422 provided at the top inside the fixing bins 421, and the bottom end of the positioning column 422 is connected to the bottom inside the fixing bin 421.

Sliding sleeve blocks 423 are fixedly installed at both ends of the connecting cross plate 426, and the sliding sleeve blocks 423 are slidably sleeved on the surface of the positioning column 422. A second spring 424 is sleeved on the top end of the surface of the positioning column 422. One end of the second spring 424 is connected to the top inside the fixing bin 421, and the other end of the second spring 424 is connected to the top of a group of sliding sleeve blocks 423 on the surface of the same group of positioning columns 422. A third spring 425 is sleeved on the bottom end of the surface of the positioning column 422. One end of the third spring 425 is connected to the bottom inside the fixing bin 421, and the other end of the third spring 425 is connected to the bottom of another group of sliding sleeve blocks 423 on the surface of the same group of positioning columns 422. A limiting socket 428 is opened at one end of the side cover plate 414 close to the connecting cross plate 426. Three operation blocks 429 are fixedly installed at the mutually remote ends of the two groups of connecting cross plates 426, and the operation blocks 429 are adapted to the limiting socket 428. And operation blocks 429 are provided on both sides at one end of the connecting cross plate 426. By using the setting of the operation blocks 429 on the two groups of connecting cross plates 426, when pinching the operation blocks 429 on the two groups of connecting cross plates 426, the two groups of connecting cross plates 426 can be made to approach, and then the restriction on the side cover plate 414 can be cancelled.

[0063] During use, after the two groups of rotating crushing rollers 23 crush the rock blocks, the crushed blocks will fall into the blanking chute opening 27, and then fall from the blanking chute opening 27 into the collection drawer 413 in a group of limiting channels 411 through the blanking port 412 for storage. When sampling different types of rock blocks, by pinching the operating blocks 429 on the two groups of connecting cross plates 426, the two groups of connecting cross plates 426 are made to approach each other. Then, the sliding sleeve blocks 423 on the connecting cross plates 426 slide on the surface of the positioning columns 422, and at the same time, the second spring 424 and the third spring 425 on the surface of the positioning columns 422 are stretched. Then, the limiting insertion blocks 427 on the connecting cross plates 426 are removed from the limiting insertion openings 428 on the side cover plate 414, and then the fixation of the side cover plate 414 is cancelled. After that, a group of collection drawers 413 filled with rock fragments can be pulled out from a group of limiting channels 411 under the blanking port 412, and then the empty collection drawers 413 in the other limiting channels 411 can be pulled out and replaced.
