Description

Technical Field

[0001] The invention relates to the technical field of ore crushing, and in particular to a sampling and crushing device for geological and mineral exploration. Background Art

[0002] Geological and mineral exploration can be observed and detected by industrial microscope according to the soil structure of geological layers. Soil can be divided into old accumulation soil, general accumulation soil and recent accumulation soil according to the accumulation age; it can be divided into gravel soil, sandy soil, silt soil and clay soil according to particle grading or plasticity index; it can be divided into inorganic soil, organic soil, carbonaceous soil and peat according to organic matter content; it can be divided into disintegrating soil, soft soil, expansive soil, saline soil, artificial fill soil, etc. according to engineering geological significance and special composition, state and structural characteristics of soil. However, in the actual geological and mineral exploration sampling operation, the gravel or ore collected in the soil has a large diameter and needs to be crushed before use. The sampling and crushing structure for geological and mineral exploration in the existing technology is not effective, which is not conducive to the detection of crushed particles of ore, judgment and collection of geological and mineral information.

[0003] The query of the disclosed prior art "CN 114405584 B, a mineral sample crushing device for geological and mineral exploration" records that "the present invention discloses a mineral sample crushing device for geological and mineral exploration, comprising a crusher body for crushing smaller blocks of ore and a support frame for supporting the crusher body, the support frame is provided with a support hole for communicating with the bottom discharge port of the crusher body, the crusher body is provided with a feeding port for putting crushed stone, a processing shell is provided above the crusher body, and support legs connected to the crusher body are provided at the four corners of the bottom of the processing shell. This mineral sample crushing device for geological and mineral exploration, through the processing shell provided above the crusher body and the dividing shell provided inside the processing shell, and under the drive of the processing mechanism and the auxiliary mechanism, the large block ore samples inside the dividing shell are initially crushed. At the same time, the crushed ore samples can be stably introduced into the crusher from the feeding port, which effectively saves manpower and improves the ore sample crushing efficiency."

[0004] However, the sample crushing device of the above-mentioned prior art still has the following technical problems: First, the structural design of the sample crushing device of the above-mentioned prior art is unreasonable. The conventional single crushing structure can only crush once, that is, the particle size of the crushed material is limited. If you want to obtain ore materials of different particle sizes, you may need to set up multiple groups of combined crushing structures with different spacings, which will cause a complex structure, occupy a large space, and greatly increase the cost. That is, the sample crushing device of the prior art cannot complete the extrusion crushing of ore materials with different spacings by single crushing in a limited space, and then meet the sampling requirements of ore samples with different particle sizes. Second, although the sample crushing device of the above-mentioned prior art solves the problem of ore crushing to a certain extent, in the actual ore crushing operation, the ore will produce a large amount of smoke and dust due to the extrusion crushing. The direct emission of smoke and dust cannot meet the emission requirements of municipal environmental protection, and will also seriously affect the air quality and endanger the health of the staff; further, in the actual ore extrusion crushing operation, it is also necessary to focus on observing the service life and wear of the extrusion components to prevent abnormal damage to the extrusion part of the crushing structure, resulting in suspension of the crushing operation and reducing the crushing efficiency and crushing quality of ore sampling.

[0023] Example: Figures 1 to 9 As shown: A sampling and crushing device for geological and mineral exploration comprises a supporting structure 1, a crushing structure 2, a dust reduction structure 3 and a screening structure 4. The present invention has a reasonable structural design, and by setting a chassis with a quasi-elliptical structure as the main extrusion and crushing part of mineral crushed stone, the spacing change of the mineral crushed stone material channel in the crushing operation state is completed through the rotation change of the minimum outer diameter R2 and the maximum outer diameter R1, thereby realizing the crushing operation of mineral crushed stone with different particle sizes, and can achieve a larger crushing demand in a smaller space, and can achieve the extrusion and crushing effect of ore materials with different spacings by completing the single-unit crushing in a limited space; at the same time, the present invention integrates a dust reduction structure in the crushing disk, with high space utilization, compact structure, and a relatively small volume of the entire structure, which saves structural space, and can compress the length by more than 30% compared with the traditional crushing structure with the same efficiency.

[0024] like Figure 1 and Figure 2As shown: wherein the support structure 1 includes a base 11 and a box 12, wherein the base 11 is distributed left and right, and the box 12 is vertically distributed and arranged on the base 11; the box and the base can be fixed by welding. The box is a hollow structure. A support leg 13 is also provided at the lower end of the base 11 for stable support. Among them, a pin 14 is provided at the lower end of the support leg 13, and the pin 14 is rotatably connected to the support leg 13 by a screw 15 to complete the horizontal support adjustment of the base 11; the pin 14 and the screw 15 are an integral structure. The purpose of such a setting is to achieve the support stability of the base, ensure the normal and reasonable operating state of stone crushing and screening, and is simple to operate, which can improve the adaptability of the crushing device and is widely applicable to the working environment of various support surfaces. In a preferred technical solution, a feed port 16 is also provided at the top of the box body 12, and a feed hopper 17 is also provided at the feed port 16; the feed port and the feed hopper can be two groups symmetrically distributed on the left and right, and such an arrangement ensures the smooth transportation of ore materials. A discharge port 18 is provided on the side wall and the bottom of the box body 12, and the discharge ports 18 on the side wall of the box body 12 are correspondingly installed at the lower inclined end of the screen plate 41. The purpose of such an arrangement is to correspond to a multi-stage screening structure. In this embodiment, two screening plates are provided to form a three-stage screening structure, and there are three corresponding discharge ports, two of which are on the side wall and one on the bottom. In a preferred embodiment, a sampling box is also connected to the discharge port on the side wall of the box body through a connecting piece, and the sampling box is a cavity structure with an opening at the top. Among them, the connecting piece can be a strong magnet sub-block and a strong magnet mother block. The strong magnet mother block is set in the groove opened in the box body, and the strong magnet sub-block is set in the groove opened in the sampling box, and the two are kept matched and installed to achieve a convenient and stable magnet adsorption structure, which is simple to install and easy to disassemble, and sampling is time-saving and labor-saving. The discharge port at the bottom of the box body can be directly installed below the discharge port, and the bottom end surface of the box body is a central concave structure, and the discharge port is set in the center for easy discharge.

[0025] like Figure 2 As shown in the figure: In this embodiment, the crushing structure 2 includes a fixed plate 21 and a crushing disk 22. The crushing disk 22 is arranged on the fixed plate 21 through a driving member 23 and can rotate. The fixed plate 21 is arranged horizontally in the box body 12; the two can be fixed by welding or bolts. Fig. 9As shown: the fixed plate 21 divides the box body 12 into an upper cavity 26 and a lower cavity 27; wherein the upper cavity 26 is a cylindrical structure; and the lower cavity 27 is a square structure. In a preferred technical solution, the driving member 23 includes a driving motor 231 and a driving shaft 232. A fixing seat 233 is also provided above the fixed plate 21, and the fixing seat and the fixed plate are also fixedly connected by sampling welding. And a ring-shaped and evenly distributed material hole 25 is also provided at the corresponding material channel 24 on the fixed plate 21. Preferably, the fixed seat 233 is a truncated cone structure with a large upper end and a small lower end; such a setting is to increase the conveying stroke by designing a material channel with an overall zigzag distribution, while improving the conveying and crushing efficiency of the ore material, and avoiding the phenomenon that linear conveying is prone to causing conveying jams. The drive motor 231 is fixedly installed inside the fixing seat 233 through a bracket, and the drive shaft 232 is vertically distributed and connected to the drive motor 231; the drive shaft 232 is connected to the chassis 223 through a keyway; the fixing seat 233 can be connected and fixed to the chassis 223 by bolts. The purpose of such a setting is to ensure that the connection is sufficiently stable while achieving disassembly and maintenance operations and convenient replacement.

[0026] like Figure 2 and Figure 4 As shown: In this embodiment, the crushing disk 22 includes a vertical portion 221, a truncated cone portion 222 and a bottom plate 223 which are integrally formed and distributed from top to bottom, wherein the bottom plate 223 has an elliptical shape, has a maximum outer diameter R1 and a minimum outer diameter R2, and maintains R1>1.2R2; a material channel 24 is formed between the side wall of the crushing disk 22 and the inner wall of the box 12; in a preferred embodiment, the bottom plate adopts an elliptical structure, that is, the width of the material channel corresponding to the bottom plate in the box changes, specifically, during the rotation of the bottom plate, taking the material channel on the left side of the box as an example, the radius of the inner wall of the box is Rx; and the minor diameter of the ellipse is R2, that is, the maximum width of the material channel is L1=Rx-R2. The major diameter of the ellipse is R1, that is, the minimum width of the material channel is L2=Rx-R1. In this way, the crushing device uses the design of a special structural bottom plate as the main part of the crushing, and realizes the purpose of completing the sampling of crushed stone materials of different degrees and different particle sizes by using a single structure. Among them, the outer diameter of the vertical part 221 is smaller than the minimum outer diameter R2 of the chassis 223, that is, the truncated cone part has a structure of being small at the top and large at the bottom. The truncated cone part 222 and the chassis 223 serve as the crushing parts for ore extrusion; particle protrusions 224 are provided on the outer side walls of the truncated cone part 222 and the chassis 223; the particle protrusions are all one-piece molded to ensure sufficient hardness. The outer side walls of the truncated cone part 222, the chassis 223 and the particle protrusions 224 are coated with a wear-resistant superhard coating 225. The purpose of such a setting is to enhance the crushing effect of the crushed stone, improve the efficiency of the ore sampling and crushing, and improve the service life of the crushing disk.

[0027] In this embodiment, after the staff has connected and installed the crushing disk and the drive shaft, when the ore crushing operation begins, the drive motor is started, and the drive motor begins to drive the drive shaft and the crushing disk to rotate synchronously. The large-sized ore passes through the larger material channel on the upper part and enters the crushing part composed of the conical part and the chassis to start the crushing operation. At this time, the particle protrusions on the conical part and the outer wall begin to pre-process and crush the large-sized ore, and the width of the material channel at the corresponding position of the crushing part gradually decreases until it enters the corresponding position of the chassis. The chassis is the main part for ore crushing. During the operation of the continuous rotation of the chassis, the special structural design of the single chassis is adopted to adjust the changes in different spacings of the material channel, and finally complete the stone crushing operation to different degrees, so as to achieve the purpose of sampling stone materials of different particle sizes.

[0028] like Figure 2 As shown: In this embodiment, the dust reduction structure 3 includes a liquid storage chamber 31, a liquid pump 32, a liquid infusion pipe 33 and an atomizing nozzle 34. The inner cavity of the vertical portion 221 and the truncated cone portion 222 is provided with the liquid storage chamber 31 adapted to the outer shape, and a liquid inlet pipe is provided on one side of the liquid storage chamber for replenishing liquid. The liquid pump 32 is fixedly installed in the liquid storage chamber 31 through a bracket, one end of the liquid infusion pipe 33 is connected to the liquid pump 32, and the other end is fixedly installed on the side wall of the vertical portion 221 through a clamp. Such an arrangement ensures the stability of the liquid infusion pipe. The atomizing nozzle 34 is fixedly installed on the liquid infusion pipe 33 and faces the material channel 24. Preferably, the liquid infusion pipe 33 is mainly composed of a main pipe 331 and a branch pipe 332. The input end of the main pipe 331 is connected to the liquid pump 32, and the output end is connected to multiple branch pipes 332 through a pipe joint. The other end of the branch pipe 332 is connected to the atomizing nozzle 34; refer to Figure 5 As shown: the branch pipes 332 and the atomizing nozzles 34 are matched and installed in multiple groups and are evenly distributed in an annular shape. This embodiment preferably adopts a structure of four groups of branch pipes and atomizing nozzles, and the main pipe can be connected to the four branch pipes using a five-way joint; in this way, when the ore begins to be crushed, the ore crushing in the material channel will generate a large amount of smoke and dust. At this time, the staff turns on the liquid pump, and the liquid pump starts to drive the water flow in the liquid storage cavity under the strong impact force. After the atomization of the atomizing nozzle, the spray dust reduction operation begins in the material channel, thereby completing most of the smoke and dust elimination operations.

[0029] In a preferred embodiment, during the actual ore crushing operation, due to the dispersion effect of smoke and dust, although the use of simple spraying to reduce dust can solve most of the smoke and dust problems, a small part of the smoke and dust still escapes and affects the health of the workers. In order to solve this problem, this embodiment adopts: the dust reduction structure 3 also includes a filter box 35, a dust suction fan 36, a dust suction pipe 37 and an exhaust pipe 38. Specifically, Figure 2 and Figure 3As shown: the filter box 35 is arranged outside the box body 12 and is an annular structure. The filter box 35 is divided into a dust suction chamber 352 and a filter chamber 353 distributed from top to bottom by a partition 351. One end of the dust suction pipe 37 leads to the box body 12, and the other end leads to the filter chamber 353. The dust suction fan 36 is fixedly installed on the partition 351 through a bracket and is arranged on the dust suction pipe 37. In a preferred technical solution, as Figure 6 As shown: a filter 39 is also provided on one side of the dust suction pipe 37, and the filter 39 includes a sleeve 391 and an activated carbon bag 392 and a PP filter cotton 393 arranged in the sleeve 391. Water is stored in the filter chamber 353, and the exhaust pipe 38 is arranged in the filter chamber 353 and is located above the water level. In this way, when the dust suction fan is turned on, under the action of strong suction, the smoke and dust in the material channel will first enter the filter through the dust suction pipe, and the large particles and small particles of impurities generated by the crushed stone will be adsorbed and filtered by the activated carbon bag and the PP filter cotton, and then the filtered airflow will enter the water in the filter chamber again, and the calcium oxide and other components generated by the crushed stone will react with the water, so as to achieve the purpose of being absorbed and purified, and finally the purified gas will be discharged through the exhaust pipe. At the same time, a filter chamber filled with water is arranged on the outside of the box body, which can also reduce the noise problem caused by ore crushing to a certain extent.

[0030] The state stipulates that dust emissions during the production of sand and gravel aggregates should comply with the provisions of GB16297, and the same requirements apply to dust generated by ore crushing. For areas with strict environmental protection requirements, more effective measures should be taken to control dust emissions and meet local environmental protection standards. For dust generated during sand and gravel processing, the present invention adopts a variety of means for comprehensive management. First, in this embodiment, an end cover can be set at the top of the box to form a barrier and dust sedimentation. The inertial sedimentation dust removal is used to reduce the amount of dust generated from the source, and to deal with the scattering, leakage and belt deviation caused by equipment defects on site. Second, the dust generated is suppressed on-site through high-pressure atomization or ultrasonic atomization dust removal, which does not cause secondary pollution and meets national environmental protection requirements. Third, by setting up the combination of dust suction fans and filters, negative pressure induced dust removal is used to control smoke and dust in places where smoke and dust are generated seriously and where it is not conducive to excessive spraying.

[0031] like Figure 2 As shown: In this embodiment, the screening structure 4 is arranged in the lower cavity 27 of the box body 12. The screening structure 4 includes a screen plate 41 and a movable member 42. The screen plate 41 is obliquely distributed in the box body 12 and is located below the fixed plate 21, and the screen plates 41 are multiple and distributed up and down, and the mesh holes of the multiple screen plates 41 distributed from top to bottom tend to gradually decrease; such a setting is convenient for realizing graded filtration and completing the collection effect of ores with different particle sizes. Specifically, as Figure 7As shown: Each of the screen plates 41 includes a mesh body 411 and a support plate 412 arranged around the mesh body 411. The mesh body mainly adopts a filter structure, and the size of the filter mesh distributed from top to bottom tends to gradually decrease. A telescopic cloth 43 is also provided on the front support plate 412, and the other end of the telescopic cloth 43 is connected to the front side wall of the box body 12; the structure of the rear support plate 412 is the same as that of the front support plate 412. Among them, the crushed ore material will fall directly on the mesh body, and then under the action of the shaking and screening of the screen plate, the small-sized ore material falls on the lower screen plate, and the large-sized ore material gathers to the corresponding discharge port under the action of inclined distribution and shaking, and then is discharged in a centralized manner. However, some ore materials will still fall from the front and rear edges during the shaking process. The purpose of setting the telescopic cloth is to ensure that the screen plate moves forward and backward while preventing the crushed ore material from falling into the lower space without screening during the shaking process. The structure is simple, the cost is low, and the cost performance is higher. As Figure 2 As shown: In this embodiment, mounting plates 51 are provided on both sides of the box 12, and a slide groove 52 is provided in the inner cavity of the mounting plate 51; slide posts 53 are provided on both sides of the support plate 412, and the slide posts 53 are matched and installed with the slide groove 52. Preferably, the screen plate 41 and the moving part 42 are two groups matched and installed and distributed up and down; the mounting plate and the screen plate are tilted and distributed in the same manner, and the tilt angle is 20-40 degrees, to ensure sufficient tilting and sliding effect of materials on the screen plate.

[0032] like Figure 2 As shown: In this embodiment, the moving member 42 is used to drive the screen plate 41 to move forward and backward to complete the shaking and screening operation of the mineral crushed stone material. Figure 8The structure shown is as follows: each group of the moving parts 42 includes a support 421, a moving motor 422, a moving shaft 423, a moving wheel 424, an eccentric shaft 425, a connecting arm 426 and a connecting shaft 427. The support 421 is fixedly mounted on the inner wall of the box body 12, the moving motor 422 is fixedly mounted on the support 421, and the moving shaft 423 is vertically distributed and connected to the output shaft of the moving motor 422. The moving wheel 424 is sleeved and mounted on the moving shaft 423, and the eccentric shaft 425 is arranged on the moving wheel 424, and there is a preset distance from the center of the moving wheel 424. The connecting shaft 427 is arranged on the support plate 412, and one end of the connecting arm 426 is hinged to the connecting shaft 427, and the other end is connected to the eccentric shaft 425 for rotation. In this way, when the staff turns on the moving motor 422, the moving motor 422 will drive the moving shaft 423 and the moving wheel 424 to rotate synchronously as a whole. Since the eccentric shaft 425 is arranged on the non-axis of the moving wheel 424, the trajectory of the eccentric shaft 425 is elliptical, and then under the guidance of the slide groove 52 and the slide column 53, the screen plate as a whole will be driven to move back and forth through the connecting arm 426, forming a shaking screening effect on the ore material, thereby enhancing the screening effect of the screen plate on the material, avoiding the material from clogging the mesh holes, and improving the screening sampling efficiency of the ore material.

[0033] The present invention can not only realize the purpose of spraying and reducing dust generated by crushed stone, but also realize the cooling operation of the crushing disk, thereby avoiding the abnormal high temperature phenomenon generated by the crushing disk when rotating to crush the ore, and to a certain extent ensures the safety of the use of the crushing disk, and further increases the service life of the crushing disk; at the same time, the present invention simplifies the manufacturing process, and improves the dynamic balance of the structure, realizes the spatial optimization and upgrading of integrated crushing-dust reduction-screening, greatly improves the operating efficiency of geological mineral crushing, and provides favorable conditions for subsequent sampling and detection of mineral materials with different particle sizes.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
