Description

Technical Field

[0001] The invention relates to the technical field of geological detection, in particular to a sample crusher for geological detection. Background Art

[0002] In the field of geological exploration, sample crushers are key sampling and analysis tools with a profound technical background and are constantly evolving. With the rapid development of modern science and technology, geological testing has increasingly higher requirements for sample crushers, which require not only high efficiency and precision, but also intelligence and environmental protection. The main function of geological sample crushers is to crush the collected rock, ore and other samples for subsequent chemical and physical analysis. In this process, the design of the crusher must fully consider the diversity and complexity of the samples to ensure the consistency and accuracy of the crushing effect;

[0003] Traditional sample crushers have obvious functional limitations and cannot meet the needs of modern geological exploration for diversified and refined sample processing. Existing crushers can often only achieve a single crushing effect, such as coarse crushing or fine crushing, and cannot flexibly switch the crushing particle size within the same device. This leads to the need to frequently replace equipment during sample processing, which not only increases the complexity of operation, but also increases the risk of sample oxidation and loss during transportation, seriously affecting the accuracy and reliability of the test results. In addition, the fine particles and dust generated by traditional crushers during the crushing process are often mixed and stored with larger particles, which not only increases the difficulty of subsequent sorting, but may also cause detection deviations due to uneven particle size. Especially when the sample contains easily oxidized or environmentally sensitive minerals, mixed storage will aggravate the change in their properties and further reduce the detection accuracy. At the same time, the adhesion of dust not only pollutes the test environment, but may also damage precision analytical instruments, affecting the accuracy of the test results.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figures 1 to 8 A sample crusher for geological detection includes a shell 1, a movable jaw base plate 29 and a fixed jaw plate assembly, the shell 1 is provided with a feeding port 13 and a discharging port 23, the shell 1 is provided with a driving mechanism for driving the movable jaw base plate 29 to move relative to the fixed jaw plate assembly, the fixed jaw plate assembly includes a first fixed jaw plate 14, a second fixed jaw plate 42 and a third fixed jaw plate 44 which are stacked in sequence from bottom to top and have crushing teeth of different sizes, and also includes a switching mechanism, the switching mechanism is used to connect the movable jaw base plate 29 with the third fixed jaw plate 44 or to connect the movable jaw base plate 29 with the second fixed jaw plate 42 and the third fixed jaw plate 44.

[0030] In some embodiments of the present application, the driving mechanism is a driving motor 12, which is installed on the top of the housing 1 through a fixing bracket 27. In other embodiments of the present application, the driving mechanism may also use other components, which is not limited in the present application.

[0031] Geological sample testing relies on measuring the chemical or physical properties of materials to test or analyze materials. Before testing, it is generally necessary to crush the samples first for subsequent testing and processing. When performing the crushing work, the staff starts the driving mechanism and then puts the sample to be crushed into the interior of the shell 1 from the feeding port 13. When the sample passes between the fixed jaw plate and the movable jaw base plate 29, it is crushed by the extrusion and crushing of the fixed jaw plate and the movable jaw base plate 29, and then the crushed sample leaves the interior of the shell 1 from the discharge port 23 on one side of the shell 1.

[0032] The above process is the basic process of sample crushing at present. However, in the actual sample crushing process, when the sample is tested, the sample will be crushed into coarse, medium and fine crushing processes according to the needs of the sample test. The crushing effect of the existing crushers is relatively single. When the sample needs to be crushed to different degrees, different crushers are usually required to perform coarse, medium and fine crushing processes respectively. In the process of transferring the sample from one crusher to another, the time the sample is in contact with the air may be increased, thereby increasing the risk of sample oxidation, especially for some easily oxidized minerals or rocks. In addition, during the transportation and crushing process, some fine particles may fall off from the sample, resulting in sample loss. This loss may affect the accuracy and reliability of subsequent analysis.

[0033] In addition, when the sample is crushed, even if it is a coarse crushing process, relatively small particles will be produced in the crushing process, and unified storage will cause certain interference to the subsequent detection process. The mixed storage of small particle fragments and larger particles may lead to the overall unevenness of the sample. In the subsequent detection, if the sampling is uneven, it may cause deviations in the test results, because particles of different particle sizes may have different physical and chemical properties. Small particle fragments have a higher specific surface area, which makes it easier to adsorb impurities in the environment or undergo chemical reactions, causing changes in the properties of the sample, which will affect the accuracy of the test results. In addition, after the sample is crushed, small particles of dust will appear on the surface of the sample after crushing. The dust may contaminate the test environment in the subsequent detection process, especially when the test environment has high requirements for cleanliness, such as when analyzed by certain precision instruments. The dust on the surface of the sample may adhere to the test instrument or sample, thereby interfering with the test results.

[0034] Therefore, in order to solve the above problems, we designed a fixed jaw plate assembly and a switching mechanism, wherein the fixed jaw plate assembly includes a first fixed jaw plate 14, a second fixed jaw plate 42 and a third fixed jaw plate 44 stacked in sequence from bottom to top and having crushing teeth of different sizes, and the switching mechanism is used to connect the movable jaw base plate 29 with the third fixed jaw plate 44 or to connect the movable jaw base plate 29 with the second fixed jaw plate 42 and the third fixed jaw plate 44.

[0035] In some embodiments of the present application, the bottom surface of the movable jaw base plate 29 is meshed with the top surface of the third fixed jaw plate 44, and small crushing teeth are provided on the side opposite to the movable jaw base plate 29 and the third fixed jaw plate 44; the bottom surface of the third fixed jaw plate 44 is meshed with the top surface of the second fixed jaw plate 42, and medium-sized crushing teeth are provided on the side opposite to the second fixed jaw plate 42; the bottom surface of the second fixed jaw plate 42 is meshed with the top surface of the first fixed jaw plate 14, and large crushing teeth are provided on the top surfaces of the second fixed jaw plate 42 and the first fixed jaw plate 14.

[0036] When fine crushing is required, the first fixed jaw plate 14, the second fixed jaw plate 42 and the third fixed jaw plate 44 are connected as a whole, the sample is located between the movable jaw base plate 29 and the third fixed jaw plate 44, and the rock is crushed by the relative movement between the movable jaw base plate 29 and the third fixed jaw plate 44. When medium crushing is required, the movable jaw base plate 29 is fixedly connected to the third fixed jaw plate 44, the first fixed jaw plate 14 is fixedly connected to the second fixed jaw plate 42, the sample is located between the second fixed jaw plate 42 and the third fixed jaw plate 44, and the rock sample is crushed by the relative movement between the second fixed jaw plate 42 and the third fixed jaw plate 44. When coarse crushing is required, the movable jaw base plate 29 is fixedly connected to the second fixed jaw plate 42 and the third fixed jaw plate 44, the sample is located between the first fixed jaw plate 14 and the second fixed jaw plate 42, and the rock sample is crushed by the relative movement between the first fixed jaw plate 14 and the second fixed jaw plate 42. Thus, flexible switching among coarse crushing, medium crushing and fine crushing is achieved.

[0037] In some embodiments of the present application, the switching mechanism includes a movable base 28, a dual-axis motor 31 is provided on both sides of the movable base 28, both output ends of the dual-axis motor 31 are connected to a rotating rod 32, a secondary hook 35 is provided on the side of the rotating rod 32, a torsion spring 33 is provided at the end of the rotating rod 32, and a main hook 34 is fixedly connected to the other end of the torsion spring 33, and the main hook 34 and the secondary hook 35 are arranged at ninety degrees, and limit plates 30 are provided on both side surfaces of the movable jaw base plate 29; A base engaging rod 41 is arranged on the side of the first fixed jaw plate 14, a middle sleeve rod 43 and a first limit block 431 are arranged on the side of the second fixed jaw plate 42, and a top sleeve 45 and a second limit block 451 are arranged on the side of the third fixed jaw plate 44. The base engaging rod 41, the middle sleeve rod 43 and the top sleeve 45 are arranged in sequence; a circular hole with the same diameter as the top sleeve 45 is opened at the center of the limit plate 30, and the main hook 34 cooperates with the second limit block 451, and the first limit block 431 cooperates.

[0038] When working, the dual-axis motor 31 can drive the rotating rod 32 to rotate, thereby driving the main hook 34 and the auxiliary hook 35 to rotate, so that the main hook 34 and the auxiliary hook 35 are respectively engaged with the first limit block 431 and the second limit block 451. Specifically, when fine crushing is performed, the base engaging rod 41 is inserted into the middle sleeve rod 43, and the middle sleeve rod 43 is inserted into the top sleeve 45, so that the first fixed jaw plate 14, the second fixed jaw plate 42 and the third fixed jaw plate 44 are connected as a whole, and the bottom of the movable jaw base plate 29 and the third fixed jaw plate 44 crush the rock sample. When medium crushing is in progress, the dual-axis motor 31 drives the rotating rod 32 to rotate a certain angle (for example, 180°), thereby driving the main hook 34 and the auxiliary hook 35 to rotate the same angle, and the main hook 34 is engaged with the second limit block 451, thereby fixing the third fixed jaw plate 44 and the movable jaw base plate 29 together, at this time, the limit plate 30 is sleeved on the top sleeve 45, at this time, the second fixed jaw plate 42 is fixed on the first fixed jaw plate 14, and medium crushing is performed through the crushing teeth between the second fixed jaw plate 42 and the third fixed jaw plate 44. When coarse crushing is in progress, the dual-axis motor 31 drives the rotating rod 32 to continue to rotate 90°, gradually compressing the torsion spring 33 and rotating the auxiliary hook 35 to the same plane as the main hook 34, and the auxiliary hook 35 is engaged with the first limit block 431, thereby fixing the third fixed jaw plate 44 and the second fixed jaw plate 42 on the movable jaw base plate 29, and coarse crushing is performed through the crushing teeth between the first fixed jaw plate 14 and the second fixed jaw plate 42.

[0039] The telescopic motor 17 drives the adjustment plate 21 and the rolling wheel 18 to move in the wheel groove, and can adjust the position of the adjustment plate 21 to adjust the size of the crushing outlet so that particles of the appropriate size can fall and be subsequently processed. When crushing small particles, the size of the outlet can be adjusted to improve the crushing accuracy to meet different crushing requirements.

[0040] At the same time, based on the above problems, we also designed a storage mechanism, which consists of a filter assembly, a material storage assembly and a dust removal assembly. The filter assembly includes: a material blocking slope 24, which is fixedly mounted on the upper surface of the inner box 16. Two motors 9 are also arranged on both side surfaces of the housing 1. A rotating disk 25 is connected to the output shaft of the motor 9. A connecting rod 46 is connected to one side surface of the rotating disk 25. A rotatable filter comb plate 47 is connected to the end of the connecting rod 46.

[0041] After the sample enters the upper surface of the inner box 16, the large particle sample is separated from the fine particles and dust through the rotation of the filter comb plate 47. The motor 9 drives the rotating disk 25 to rotate, and then drives the filter comb plate 47 to rotate, so that the coarsely crushed sample passes over the highest point of the material blocking slope 24 under the combing action of the filter comb plate 47, and slides down along the material blocking slope 24 under the action of gravity and enters the coarse crushing collection box 7 through the feed reserved port 40. The coarse crushing collection box 7 can be taken out to facilitate sample transfer.

[0042] The material storage component includes: a coarse crushing collection box 7 is also fixedly installed on one side surface of the shell 1, a removable inner box 36 is arranged inside the coarse crushing collection box 7, and three hook blocks 37 for fixing with the coarse crushing collection box 7 are also arranged on the upper surface of the inner box 36, a movable box cover 38 is connected to the upper surface of the coarse crushing collection box 7 through a rotating shaft, and a positioning block 39 is fixedly installed on the bottom surface of the box cover 38, and a card groove matching with the positioning block 39 is provided on the upper surface of the coarse crushing collection box 7, and a feed reserved port 40 matching with the discharge port 23 is also provided on one side surface of the box cover 38.

[0043] The medium-crushed and fine-crushed samples will not be combed by the filter comb plate 47, but will slide along the slope toward one side of the storage box 48 and enter the interior thereof. The storage box 48 is provided with a medium-crushed collection drawer 10 and a fine-crushed collection drawer 11. The long groove design of the medium-crushed collection drawer 10 allows small particle samples to pass through when receiving the materials, so that the small particle samples fall into the fine-crushed collection drawer 11 below, thereby further separating the sample particle size.

[0044] The dust removal assembly includes: a fan, which is arranged inside the housing 1, a dust box 3 is also arranged on one side surface of the housing 1, a side surface of the dust box 3 is communicated with the inside of the storage box 48, a side surface of the dust box 3 is arranged with an interception net 4 matched with the fan, and a bottom surface of the interception net 4 is arranged with an openable cover plate 5;

[0045] After the fan is started, an airflow is generated to suck the dust in the housing 1 into the dust box 3, and the dust is intercepted and discharged through the interception net 4. At the same time, the openable cover 5 can facilitate the cleaning of the dust in the dust box after use.

[0047] During the crushing process, the bottom spring block 20 and the elastic block 15 transmit the vibration of the crushing place to the inner box 16 and the storage box 48 through the vibration transmission block, so that the crushed samples stored inside are vibrated, so as to stir up the dust on the surface of the sample, remove it through the dust removal component, and accelerate the movement of the sample inside, so as to prevent internal blockage and accelerate the flow of the sample.

[0048] In some embodiments of the present application, a base 2 is provided at the bottom of the shell 1, and a movable door 6 is connected to one side surface of the shell 1 through a hinge. The movable door 6 is provided with a visual window. A rotatable knob switch 8 is also provided on the surface of the movable door 6, and a handle is fixedly installed on the side surface of the knob switch 8.

[0049] The working principle of the present invention is:

[0050] When in use, the staff puts the sample to be crushed into the shell 1 from the feeding port 13. When the sample passes between the fixed jaw plate assembly and the movable jaw base plate 29, it is crushed by the extrusion and crushing of the fixed jaw plate assembly and the movable jaw base plate 29.

[0051] In the process of crushing, the switching mechanism can be used to flexibly switch between coarse crushing, medium crushing and fine crushing. Specifically, the dual-axis motor 31 can drive the rotating rod 32 to rotate, thereby driving the main hook 34 and the auxiliary hook 35 to rotate, so that the main hook 34 and the auxiliary hook 35 are respectively engaged with the first limit block 431 and the second limit block 451. Specifically, when fine crushing is performed, the base engagement rod 41 is inserted into the middle sleeve rod 43, and the middle sleeve rod 43 is inserted into the top sleeve 45, so that the first fixed jaw plate 14, the second fixed jaw plate 42 and the third fixed jaw plate 44 are connected as a whole, and the bottom of the movable jaw base plate 29 and the third fixed jaw plate 44 crush the rock sample. When medium crushing is in progress, the dual-axis motor 31 drives the rotating rod 32 to rotate a certain angle (for example, 180°), thereby driving the main hook 34 and the auxiliary hook 35 to rotate the same angle, and the main hook 34 is engaged with the second limit block 451, thereby fixing the third fixed jaw plate 44 and the movable jaw base plate 29 together, at this time, the limit plate 30 is sleeved on the top sleeve 45, at this time, the second fixed jaw plate 42 is fixed on the first fixed jaw plate 14, and medium crushing is performed through the crushing teeth between the second fixed jaw plate 42 and the third fixed jaw plate 44. When coarse crushing is in progress, the dual-axis motor 31 drives the rotating rod 32 to continue to rotate 90°, gradually compressing the torsion spring 33 and rotating the auxiliary hook 35 to the same plane as the main hook 34, and the auxiliary hook 35 is engaged with the first limit block 431, thereby fixing the third fixed jaw plate 44 and the second fixed jaw plate 42 on the movable jaw base plate 29, and coarse crushing is performed through the crushing teeth between the first fixed jaw plate 14 and the second fixed jaw plate 42.

[0052] In addition, the telescopic motor 17 can assist in adjusting the position of the adjusting plate 21 by driving the adjusting plate 21 and the rolling wheel 18 to move in the wheel groove, so as to adjust the size of the crushing outlet so that only particles of the appropriate size can fall and be subsequently processed. When crushing small particles, the crushing accuracy can be improved by adjusting the size of the outlet to meet different crushing requirements.

[0053] After the sample enters the upper surface of the inner box 16, the large particle sample is separated from the fine particles and dust by the rotation of the filter comb plate 47. The motor 9 drives the rotating disk 25 to rotate, and then drives the filter comb plate 47 to rotate, so that the coarsely crushed sample passes over the highest point of the material blocking slope 24 under the combing and filtering action of the filter comb plate 47, and slides along the material blocking slope 24 under the action of gravity and enters the coarse crushing collection box 7 through the feed reserved port 40. The inner box 36 can be taken out to facilitate sample transfer. The medium and fine crushed samples will not be combed by the combing of the filter comb plate 47, but will slide toward one side of the storage box 48 along the slope and enter its interior. The storage box 48 is provided with a medium crushing collection drawer 10 and a fine crushing collection drawer 11. The long groove design of the medium crushing collection drawer 10 allows small particle samples to pass through when receiving the materials, so that the small particle samples fall into the fine crushing collection drawer 11 below, further separating the sample particle size.

[0054] During the crushing process, the bottom spring block 20 and the elastic block 15 transmit the vibration of the crushing place to the inner box 16 and the storage box 48 through the vibration transmission block, so that the crushed samples stored inside are vibrated, so as to stir up the dust on the surface of the sample, remove it through the dust removal component, and accelerate the movement of the sample inside, so as to prevent internal blockage and accelerate the flow of the sample.

[0055] After the fan is started, it generates airflow to suck the dust in the shell 1 into the dust box 3, and the dust is intercepted and discharged through the interception net 4. At the same time, the openable cover 5 can facilitate the cleaning of the dust in the dust box after use.
