Description

Technical Field

[0001] The present invention relates to the technical field of mineral product detection, and in particular to a crushing and reducing device for mineral product detection. Background Art

[0002] Before testing, mineral products usually need to go through steps such as crushing, screening, mixing, and reduction to prepare them into analytical samples that can represent the characteristics of the original mineral samples. Mineral products are generally crushed by a jaw crusher. The purpose of crushing is to refine the mineral products into particles suitable for subsequent reduction. The purpose of subsequent reduction is to obtain the mineral product samples required for testing while ensuring the representativeness of the samples. The reduction is mainly completed by a binary divider. However, the reduction ratio of the binary divider reduction method is fixed at 1 / 2, the sample preparation efficiency is low, and the sample reduction time is long, which cannot meet the needs of a variety of reduction tasks.

[0003] In the prior art, for example, the patent document with publication number CN220231165U proposes a crushing and reducing device for mineral product detection, including a crushing device and a reducing machine, the reducing machine includes a shell, a sieve plate, a material dividing structure, a material receiving tray and a waste port, the crushing device outlet is connected to the shell top inlet, there are two sieve plates, the material dividing structure and the material receiving tray are arranged under the sieve plates in sequence, and the waste port is arranged at the bottom of the shell and connected to the outside world. This technical solution crushes the mineral sample through the crushing device, and then evenly reduces the sample into multiple parts through the material dividing structure and the material receiving tray, which effectively improves the sample preparation efficiency.

[0004] However, the above-mentioned prior art still has the following limitations in actual use:

[0005] (1) Although the above technical solution can realize the reduction of crushed mineral products by setting a material dividing structure under the screen plate, the number of channels for the crushed mineral products to pass through the material dividing structure is fixed, and the opening and closing of the channels cannot be controlled. Therefore, only a fixed number of reductions can be achieved, and the function is relatively simple;

[0006] (2) It is difficult for the jaw crusher to fully crush the mineral products, which may result in a small amount of large-volume individuals that do not meet the reduction requirements in the crushed mineral products. The screening process generally uses a screen to intercept such large-volume individuals, and after collection, these large-volume individuals are crushed again to meet the reduction requirements. However, the use of a screen alone for screening will be blocked by the continuous input of large-volume crushed mineral products, resulting in the screening structure being unable to perform the screening function.

[0051] Embodiment 1

[0052] Combine the following Figures 1 to 9 As shown, an embodiment of the present invention provides a crushing and reducing device for mineral product detection, comprising a machine body 1, a crushing mechanism 2 is installed on the top of the machine body 1, a screening component 3, a collecting bucket 4, a dividing cone 6, a hydraulic base component 7 and a dividing plate 5 are installed in sequence from top to bottom inside the machine body 1, the output end of the crushing mechanism 2 extends into the interior of the machine body 1, the screening component 3 is used to screen the crushed material output by the crushing mechanism 2, the collecting bucket 4 is used to collect the screened material of the screening component 3 and concentrate it to the central output port, the dividing cone 6 is located below the collecting bucket 4 and fits the inner side of the output port of the collecting bucket 4, the dividing cone 6 has a plurality of channels for the crushed material to pass through, the hydraulic base component 7 is connected to the dividing cone 6 and can control the multiple channels of the dividing cone 6 to be synchronously connected or closed, and the dividing plate 5 has independent storage areas corresponding to the multiple channels on the collecting bucket 4 one by one;

[0053] The outside of the machine body 1 is provided with a shaking screen assembly 9 and an independent hydraulic assembly 8 from top to bottom. The shaking screen assembly 9 is connected to the screening assembly 3 and is used to control the screening assembly 3 to make high-frequency reciprocating motion. The independent hydraulic assembly 8 is connected to the hydraulic base assembly 7 and is used to control the connection of any channel of the dividing cone 6.

[0054] The present invention provides a dividing cone 6 to block the bottom output port of the collecting bucket 4, a plurality of arc-shaped channels 61 are provided on the dividing cone 6, a hydraulic base assembly 7 is provided below the dividing cone 6 to control the synchronous opening or closing of the plurality of arc-shaped channels 61 on the dividing cone 6, an independent hydraulic assembly 8 is provided on the hydraulic base assembly 7 to control the opening or closing of any number of arc-shaped channels 61 on the dividing cone 6, thereby enabling the crushing of mineral products in different quantities to be reduced.

[0055] The screening component 3 provided in the present invention can move laterally in the machine body 1. By arranging a shaking screen component 9 outside the machine body 1 to control the screening component 3 to perform high-frequency reciprocating movement in the machine body 1, the continuously input large-volume crushed mineral products are not easy to clog the filter mesh holes of the screen drawer 33, thereby greatly reducing the probability of the screen drawer 33 being blocked.

[0056] Among them, the shaking screen assembly 9 includes a mounting shell 91 fixedly connected to both sides of the inner wall of the body 1, a motor 92 is installed at the bottom of the mounting shell 91, the output end of the motor 92 extends into the interior of the mounting shell 91 and is connected to a turntable 93, a hinged rod 94 is hinged on the turntable 93, one end of the hinged rod 94 is hinged to a third connecting rod 95, one end of the third connecting rod 95 extends into the body 1 and is connected to the screening assembly 3.

[0057] The screening assembly 3 includes a connecting plate 31 connected to the end of the third connecting rod 95, and both ends of the connecting plate 31 are slidably connected with slide rails 32. The two slide rails 32 are transversely connected to the inner wall of the body 1, and a screen drawer 33 is slidably connected between the two slide rails 32. The screen drawer 33 can slide laterally out of the body 1. The screen drawer 33 is provided with two positioning rods 34 that pass through the screen drawer 33 laterally. The front end of the screen drawer 33 is rotatably connected with two clamping rods 35. The front ends of the two positioning rods 34 are provided with clamping grooves 341. The two clamping rods 35 can be rotated to engage with the clamping grooves 341 on the two positioning rods 34.

[0058] The crushed ore outputted by the crushing mechanism 2 will directly fall into the screen drawer 33 of the screening assembly 3, wherein the crushed ore with a volume smaller than the mesh at the bottom of the screen drawer 33 will pass through the screen drawer 33 and fall into the collecting bucket 4 below, while the crushed ore with a volume larger than the mesh at the bottom of the screen drawer 33 will be intercepted in the screen drawer 33. If the screen drawer 33 is in a stationary state, the large volume of crushed ore continuously inputted will block the mesh at the bottom until the screen drawer 33 cannot screen the crushed ore. By starting the motor 92 of the shaking screen assembly 9, the turntable 93 installed on the output end of the motor 92 rotates. Since one end of the hinged rod 94 is hinged at a non-center position on the turntable 93, the third connecting rod 95 can be driven by the hinged rod 94 to perform a reciprocating telescopic motion on the machine body 1 as the turntable 93 rotates.

[0059] The screen drawer 33 of the screening assembly 3 is used to screen the crushed ore. When installing the screen drawer 33, it is necessary to slide the two sides of the screen drawer 33 with the two slide rails 32. In the process of extending the screen drawer 33 into the machine body 1, the two positioning rods 34 on the connecting plate 31 gradually pass through the screen drawer 33 until the screen drawer 33 contacts the connecting plate 31. At this time, the front ends of the two positioning rods 34 pass through the screen drawer 33. By rotating the two clamping rods 35 on the screen drawer 33, the two clamping rods 35 are engaged in the clamping grooves 341 on the two positioning rods 34, so that the screen drawer 33 is connected to the connecting plate 31. The third connecting rod 95, the connecting plate 31 and the screen drawer 33 perform reciprocating motion synchronously, so that the large volume of crushed ore in the screen drawer 33 can be shaken to expose the mesh for screening.

[0060] The material distribution cone 6 is provided with a plurality of arc-shaped channels 61 evenly distributed around its conical surface, the bottom ends of the plurality of arc-shaped channels 61 extend to the lower surface of the material distribution cone 6, the plurality of arc-shaped channels 61 are provided with outer sliding cavities 62, the lower surface of the material distribution cone 6 is provided with a plurality of bottom sliding cavities 63 corresponding to the plurality of outer sliding cavities 62, and the bottom sliding cavities 63 and the corresponding outer sliding cavities 62 are connected by a connecting channel 64;

[0061] Elastic spacers 65 are connected to multiple arc-shaped channels 61, and a support rod assembly 66 for connecting the elastic spacers 65 is slidably connected in the outer sliding cavity 62. The support rod assembly 66 slides in the outer sliding cavity 62 to switch the elastic spacers 65 to an expanded or retracted state. The dividing cone 6 and multiple elastic spacers 65 in the expanded state together constitute a conical structure that blocks the output port at the bottom end of the collecting bucket 4.

[0062] Side grooves 611 are formed on both sides of the arc-shaped channel 61, and both sides of the elastic spacer 65 extend into the side grooves 611 on both sides of the arc-shaped channel 61;

[0063] When in the expanded state, the elastic spacer 65 is flush with the inclination of the conical surface of the distribution cone 6 to block the corresponding channel on the distribution cone 6. When in the retracted state, the elastic spacer 65 fits with the inner wall of the arc channel 61 to connect the corresponding channel on the distribution cone 6.

[0064] The support rod assembly 66 includes a first piston 661 slidably connected in the outer sliding cavity 62, one end of the first piston 661 is provided with a first connecting rod 662, one end of the first connecting rod 662 passes through the outer sliding cavity 62 and is connected to a flexible connecting piece 663, and the flexible connecting piece 663 is connected to the inner wall of the corresponding elastic spacer 65;

[0065] When the first piston 661 is at the frontmost position in the outer sliding cavity 62 , the elastic spacer 65 is in an extended state, and when the first piston 661 is at the rearmost position in the outer sliding cavity 62 , the elastic spacer 65 is in a retracted state.

[0066] Specifically, the crushed ore passing through the screening component 3 will fall on the collecting bucket 4 and automatically converge to the output port in the center of the collecting bucket 4 due to the height difference. If the multiple elastic spacers 65 on the dividing cone 6 are all in the expanded state at this time, multiple arc channels 61 will be blocked, making it impossible for the crushed ore gathered in the collecting bucket 4 to pass through the dividing cone 6. The hydraulic base component 7 can be used to control the multiple elastic spacers 65 to retract or expand synchronously.

[0067] When the hydraulic base assembly 7 controls the synchronous retraction of multiple elastic spacers 65, it will synchronously suck the strut assemblies 66 in the multiple outer sliding chambers 62. When negative pressure is generated in the outer sliding chamber 62 to suck the strut assemblies 66, the first piston 661 will slide toward the inside of the outer sliding chamber 62, and move synchronously with the first connecting rod 662 and the flexible connecting piece 663. As the flexible connecting piece 663 moves, it will tend to retract together with the elastic spacer 65 in the expanded state, until the elastic spacer 65 is fully retracted and fits the inner side of the corresponding arc-shaped channel 61. Conversely, when the outer sliding chamber 62 is pressurized, the first piston 661 will slide toward the outside of the outer sliding chamber 62, and move synchronously with the first connecting rod 662 and the flexible connecting piece 663. As the flexible connecting piece 663 moves, it will tend to expand together with the elastic spacer 65 in the retracted state, until the elastic spacer 65 is fully expanded and fits the bottom output end of the collecting bucket 4.

[0068] Since the shape of the elastic spacer 65 is arc-shaped when it is in the expanded state and the retracted state that fits the arc-shaped channel 61, in the process of the elastic spacer 65 switching from the expanded state to the retracted state, the shape of the elastic spacer 65 needs to go through a process from an outer arc shape to a straight plate shape and then to an inner arc shape. Therefore, the two sides of the elastic spacer 65 need to extend into the interior of the two side grooves 611 for a certain distance to prevent it from detaching during the deformation of the elastic spacer 65.

[0069] Among them, the hydraulic base assembly 7 includes a sliding tube 71 fixedly connected to the bottom end of the dividing cone 6, the bottom end of the sliding tube 71 is connected to a bottom cylinder 72, the interior of the sliding tube 71 is longitudinally slidably connected to an inner sliding plate 73, the bottom of the inner sliding plate 73 is connected to a plurality of vertically distributed hydraulic pipe assemblies 74, the outside of the sliding tube 71 is provided with a triangular connecting tube 75 for connecting to the machine body 1, the bottom of the bottom cylinder 72 is provided with a protective shell 76 connected to the triangular connecting tube 75, the outside of the machine body 1 is fixedly connected to a hydraulic oil box 78, a first pump body 77 connected thereto is installed on the hydraulic oil box 78, and the output end of the first pump body 77 is provided with a hose connected to the bottom cylinder 72.

[0070] Multiple hydraulic pipe assemblies 74 correspond one-to-one to multiple bottom sliding cavities 63. The hydraulic pipe assembly 74 includes a hydraulic pipe 741 connected to the bottom of the inner sliding plate 73. The hydraulic pipe 741 is internally slidably connected to a second piston 742. The top end of the second piston 742 is provided with a second connecting rod 743 that passes through the inner sliding plate 73. The top end of the second connecting rod 743 extends into the corresponding bottom sliding cavity 63 and is connected to a third piston 744. The third piston 744 is always located in the bottom sliding cavity 63 and slides longitudinally. The bottom of the hydraulic pipe 741 is provided with a redundant hose 745 that is connected to the interior thereof. The bottom end of the redundant hose 745 is connected to a joint 746. The joint 746 is connected to the bottom end of the bottom cylinder 72 and the bottom end of the joint 746 extends out of the bottom cylinder 72.

[0071] Specifically, the hydraulic base assembly 7 is used as the mounting base of the material distribution cone 6, and is also used as a structure for synchronously driving multiple elastic spacers 65 to expand or retract. When any arc channel 61 on the material distribution cone 6 is connected, the crushed ore collected in the collecting bucket 4 can fall into the corresponding independent storage area on the lower material distribution plate 5 through the arc channel 61. When it is necessary to control the expansion of multiple elastic spacers 65 to block the output port of the collecting bucket 4, the hydraulic oil in the hydraulic oil box 78 is sucked by the first pump body 77 and pumped to the bottom cylinder 72 through the hose. As the pressure in the bottom cylinder 72 increases, the inner slide The disk 73 slides upward in the sliding tube 71 until the upper surface of the inner sliding disk 73 contacts the bottom of the dividing cone 6. At this time, the inner sliding disk 73 slides up to the maximum position. During the sliding upward process of the inner sliding disk 73, the multiple hydraulic pipe assemblies 74 installed on the inner sliding disk 73 move synchronously. The multiple hydraulic pipe assemblies 74 synchronously pressurize the interior of the multiple bottom sliding cavities 63. The multiple bottom sliding cavities 63 pressurize the interior of the multiple outer sliding cavities 62 through the corresponding multiple connecting channels 64, thereby controlling the extension of the multiple strut rod assemblies 66. Conversely, the sliding of the inner sliding disk 73 can control the retraction of the multiple strut rod assemblies 66.

[0072] When the multiple hydraulic pipe assemblies 74 move, the interior of the multiple hydraulic pipe assemblies 74 is in a closed state, so the second piston 742 will not slide longitudinally in the hydraulic pipe 741. Similarly, the second connecting rod 743 and the third piston 744 will not be displaced longitudinally. Since the third piston 744 is always located in the bottom sliding cavity 63, the corresponding bottom sliding cavity 63, the connecting channel 64 and the outer sliding cavity 62 will be pressurized during the upward sliding process of the third piston 744. When the third piston 744 slides down, the hydraulic oil in the corresponding bottom sliding cavity 63, the connecting channel 64 and the outer sliding cavity 62 will be sucked.

[0073] Among them, the independent hydraulic component 8 includes a second pump body 81 installed on the hydraulic oil box 78 and connected thereto. The output end of the second pump body 81 is connected to a porous cylinder 82 through a hose. The porous cylinder 82 is located on the inner side of the triangular connecting tube 75. The porous cylinder 82 has an input end and multiple output ends. The multiple output ends of the porous cylinder 82 are all connected to solenoid valves 83. The output ends of the multiple solenoid valves 83 are all connected to connecting pipes 84. The multiple connecting pipes 84 are connected one-to-one with the multiple joints 746.

[0074] The hose connected to the output end of the first pump body 77 extends into the triangular connecting pipe 75 and the protective shell 76 in sequence to be connected to the bottom cylinder 72, and the multiple connecting pipes 84 all extend into the protective shell 76 and are connected to the multiple joints 746 respectively.

[0075] Specifically, after the hydraulic base assembly 7 controls the synchronous expansion of the plurality of elastic spacers 65, the independent hydraulic assembly 8 is used to retract the one or more elastic spacers 65 in the expanded state, so that any number of arc-shaped channels 61 on the material distribution cone 6 can be controlled to be connected. When the plurality of elastic spacers 65 on the material distribution cone 6 are expanded to block the output port of the collecting bucket 4, if it is necessary to connect any of the elastic spacers 65, it is necessary to release the internal closed state of the hydraulic pipe assembly 74 corresponding to the elastic spacer 65, and control the corresponding solenoid valve 83 to be connected, so that the interior of the hydraulic pipe assembly 74 is connected through the corresponding connecting pipe 84 and the electric The magnetic valve 83 is connected to the interior of the porous cylinder 82. At this time, the second pump body 81 is controlled to suck the interior of the porous cylinder 82 so that the hydraulic oil in the porous cylinder 82 is pumped into the hydraulic oil box 78, so that negative pressure is generated inside the porous cylinder 82 until the second piston 742 inside the corresponding hydraulic pipe assembly 74 is sucked down through the corresponding connecting pipe 84. As the second piston 742 slides down, it will slide down synchronously with the second connecting rod 743 and the third piston 744. When the third piston 744 slides down from the corresponding bottom sliding cavity 63, it will suck the interior of the corresponding outer sliding cavity 62, so that the support rod assembly 66 inside the outer sliding cavity 62 will retract synchronously.

[0076] Embodiment 2

[0077] like Fig.10As shown, the rest of this embodiment is consistent with the first embodiment, except that the number of screen drawers 33 of the screening assembly 3 is set to two and distributed up and down, and the other related structures for connecting the two screen drawers 33 are also modified accordingly. The crushed mineral products output by the crushing mechanism 2 need to pass through at least one screen drawer 33 before falling into the collecting bucket 4 below. Therefore, during the screening process, if the number of large-volume crushed mineral products in any screen drawer 33 is excessive, the screen drawer 33 can be taken out at any time, and the large-volume crushed mineral products in the screen drawer 33 can be poured back into the crushing mechanism 2. In this process, the screening function is realized by another screen drawer 33.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
