Description

Technical Field

[0001] The present invention belongs to the technical field of geological exploration, and in particular relates to an automatic cleaning and collection system and method for geological rock samples. Background Art

[0002] During the geological exploration process, collecting rock samples is an important means to understand underground resources. Traditional rock sample collection and processing methods often require manual cleaning. The collected mud is transported manually to the solid-liquid separation device, and then the separated rock debris is cleaned, dried, and weighed to obtain a quantitative rock debris sample. This not only takes time and effort and is costly, but also may cause sample contamination, making it difficult to guarantee the quality of the collected rock debris samples, thus affecting the accuracy of subsequent analysis.

[0003] Therefore, in order to improve the efficiency and accuracy of geological exploration and sampling work, a high-tech device needs to be developed, and an automatic cleaning and collection system for geological rock samples is required to significantly improve work efficiency, reduce manual operation errors, and lower labor intensity, and to remove impurities on the rock samples and maintain the purity of the rock samples. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic cleaning and collection system and method for geological rock samples, which can improve the work efficiency of rock sample collection, reduce manual operation errors, lower labor intensity, and ensure the purity of rock samples.

[0005] In the first aspect, the present invention provides an automatic cleaning and collection system for geological rock samples, including a suction sampling mechanism, a solid-liquid separation mechanism, a sample weighing mechanism, a sample conveying mechanism, a cleaning and drying mechanism, and a sample stacking mechanism, wherein: The suction sampling mechanism is used to pump out the mud in the mud conveying pipeline and send it into the solid-liquid separation mechanism; The solid-liquid separation mechanism is used to perform solid-liquid separation on the mud to obtain rock debris samples; The sample weighing mechanism is used to weigh the rock debris samples obtained by solid-liquid separation; The sample conveying mechanism is used to convey a certain mass of rock debris samples from the sample weighing mechanism to the cleaning and drying mechanism; The cleaning and drying mechanism is used to clean and dry the rock debris samples; The sample stacking mechanism is used to cache and transfer the rock debris samples output by the cleaning and drying mechanism.

[0006] When the system automatically cleans and collects geological rock samples, the mud in the mud conveying pipeline is pumped by the sampling mechanism and then sent into the solid-liquid separation mechanism for solid / liquid separation first. The solid-liquid separation process is the core of the entire mud treatment process, and its task is to efficiently separate the mud into two parts: cuttings and waste liquid. The cuttings obtained by filtering the cuttings samples separated by the solid-liquid separation mechanism are collected by the collection device, i.e., the sample box, and the separated waste liquid is discharged into the waste liquid collection tank and discharged or reused after simple treatment. Then, the sample weighing mechanism weighs the collected cuttings samples in real time to control the mass of the cuttings samples contained in each sample box. When the sample box reaches the set weight, the sampling mechanism will stop sampling, and at the same time, the sample box filled with cuttings will be sent into the sample conveying mechanism to transfer and temporarily store the sample box filled with cuttings until the sample box is sent into the cleaning and drying mechanism for further treatment. After that, the cleaning and drying mechanism cleans and dries the cuttings samples in the sample box. Finally, the sample stacking mechanism transfers and temporarily stores the sample box filled with cuttings. Thus, the system realizes the full-automatic cleaning and collection from mud to cuttings samples. Through the organic cooperation of the above-mentioned various structures, the transformation from mud liquid to quantitative cuttings samples is achieved in a short time, greatly reducing manual operations, shortening the time for collecting and processing cuttings, and improving work efficiency. At the same time, during the cleaning and collection process, the weighing process can be accurately controlled to achieve quantitative collection of samples, reduce human errors, and ensure the accuracy and consistency of data.

[0007] Further, the sampling mechanism includes a mud suction pipe, a control valve, a suction pump, and a funnel. The inlet end of the mud suction pipe is communicated with the mud conveying pipeline. The control valve and the suction pump are arranged on the mud suction pipe. The outlet end of the mud suction pipe is connected with a funnel, and the funnel is located above the inlet end of the solid-liquid separation mechanism.

[0008] When the system cleans and collects rock samples, the mud in the mud conveying pipeline first comes to the control valve. After the control system of the system determines that rock sample sampling is required, the control valve is opened, and at the same time, the suction pump is started synchronously. Finally, it flows out through the tapered outlet of the funnel and enters the solid-liquid separation mechanism under the action of gravity, the pressure of the subsequent fluid, and inertia, realizing the sampling of the mud; otherwise, the control valve is closed, and the mud bypasses the system and is directly discharged after treatment.

[0009] Further, a valve support is provided at the bottom of the control valve, and a pump support is provided at the bottom of the suction pump.

[0010] Through the setting of the valve support and the pump support, the heights of the control valve and the suction pump can be adapted to the mud suction pipe, thereby reducing the implementation difficulty of the device.

[0011] Further, the solid-liquid separation mechanism uses a sample box with water filtering holes.

[0012] Through the filter screens around the sample box, under the action of gravity, the pressure of subsequent fluids, and inertia, solid-liquid separation of the mud is achieved. The solid-phase particles (cuttings) are intercepted in the sample box, while the liquid phase (waste liquid) passes through the filter screens and flows out from the lower opening. With such a design, not only is it convenient and fast to achieve solid-liquid separation of the mud without power, but also the solid-liquid separation mechanism formed by the sample box can circulate among various processes of the system under the action of the sample conveying mechanism and the sample stacking mechanism, enabling the sample box to be recycled and achieving lower costs.

[0013] Further, the sample weighing mechanism includes a weighing support, a weighing frame, a weighing conveying component, a weighing conveying component, a weighing plate, weighing sensors, a drain port, a rotating motor, and a paddle. The weighing support is fixedly connected to the bottom of the weighing frame. The weighing conveying component is embedded in the weighing frame to achieve the conveying connection between the sample weighing mechanism and the sample conveying mechanism. The rotating motor is fixed at the center of the bottom of the weighing frame. The output shaft of the rotating motor extends upward into the weighing frame and is rotatably connected to the paddle. A weighing plate is provided in the weighing frame below the paddle. The bottom of the weighing plate is connected to the weighing frame through a plurality of weighing sensors. A drain port is opened on the weighing frame beside the weighing plate.

[0014] During the solid-liquid separation process of the rock sample, the solid-liquid separation mechanism is placed on the weighing plate to achieve real-time weighing of the collected cuttings through the weighing sensors. The liquid formed after solid-liquid separation is discharged from the sample weighing mechanism through the drain port. After the sample box, i.e., the solid-liquid separation mechanism, reaches the set weight, the sampling mechanism will be controlled to stop sampling, and then the rotating motor will be controlled to rotate to drive the paddle to rotate by a certain angle, so as to send the sample box, i.e., the solid-liquid separation mechanism, into the sample conveying mechanism to convey the sample box to the cleaning and drying mechanism for further processing. During the implementation process, in order to control the mass of cuttings contained in each sample box, the weighing process is not completed at one time, but in twenty times, to ensure that the error is within five percent, thereby ensuring the accuracy and consistency of the data.

[0015] Further, the cross-section of the paddle is in the shape of a cross. Two weighing conveying components are symmetrically arranged with the paddle as the center. The weighing plate and the weighing sensors are arranged near the end of any one of the weighing conveying components.

[0016] Through the above settings, the sample weighing mechanism can cooperate with two sample conveying mechanisms, which can accelerate the rhythm of solid-liquid separation and weighing, improve the working efficiency of the system, and at the same time can store more sample boxes through the settings of the two sample conveying mechanisms.

[0017] Furthermore, the sample conveying mechanism includes a conveying bracket, a conveying frame, a conveying transmission assembly and a conveying steering assembly. The bottoms of the multiple conveying frames are respectively connected to the tops of the multiple conveying brackets one by one. A conveying transmission assembly is arranged in each conveying frame, and the conveying steering assembly is arranged on the conveying frame between adjacent conveying transmission assemblies.

[0018] Based on the above design, the solid-liquid separation mechanism moves in the conveying frame under the action of the conveying transmission assembly and the conveying steering assembly, thereby realizing the caching and transfer of the solid-liquid separation mechanism output by the sample weighing mechanism to the cleaning and drying mechanism. At the same time, the adjacent conveying transmission assemblies are connected through the setting of the conveying steering assembly, so as to achieve the dual functions of changing the conveying direction of the solid-liquid separation mechanism and increasing the storage capacity of the sample conveying mechanism.

[0019] Furthermore, the conveying steering assembly includes a steering bracket, a steering support, a steering motor, a steering wheel, a driven wheel, and a transmission belt. The steering support is fixed to the top of the steering bracket and fixedly connected to the conveying bracket. The steering motor is fixed on the steering support. The upper steering wheel is arranged on the output shaft of the steering motor. The driven wheel is arranged on the conveying frame between adjacent conveying transmission assemblies. The steering wheel and the driven wheel are connected by a transmission belt.

[0020] Based on the above-mentioned conveying and steering assembly, the steering wheel, the driven wheel and the transmission belt constitute a transmission structure. The rotation of the steering motor can drive the rotation of the driven wheel, thereby realizing the conveying of the solid-liquid separation mechanism.

[0021] Furthermore, the cleaning and drying mechanism includes a cleaning and drying bracket, on which a cleaning shell and a cleaning motor are installed, a carrying plate and an adsorption and fixing assembly located above the carrying plate are provided in the cleaning shell, a rotating shaft is connected to the bottom of the carrying plate, and the rotating shaft extends downwardly out of the cleaning shell, and the output shaft of the cleaning motor is connected to the rotating shaft through a cleaning transmission assembly, and a plurality of electric push rods are provided at the inner bottom of the cleaning shell on the peripheral side of the rotating shaft, and the telescopic ends of the plurality of electric push rods are naturally located below the carrying plate, and the telescopic ends of the plurality of electric push rods can pass through the carrying plate and be connected to the bottom of the adsorption and fixing assembly when extended, a water spray assembly and a drying assembly are also provided in the cleaning shell, a water outlet is provided at the bottom of the cleaning shell, and a loading and unloading assembly is also fixed to the cleaning and drying bracket.

[0022] When the cleaning and drying mechanism cleans and dries the solid-liquid separation mechanism conveyed by the sample conveying mechanism, first, the electric push rod ejects the adsorption and fixation component. Then, the loading and unloading component grabs the solid-liquid separation mechanism from the sample conveying mechanism and places it on the adsorption and fixation component. The adsorption and fixation component firmly adsorbs the solid-liquid separation mechanism. After that, the electric push rod retracts, and the adsorption and fixation component and the supporting plate are combined into one. The cleaning motor is controlled to drive the adsorption and fixation component, the supporting plate, and the solid-liquid separation mechanism to rotate through the cleaning transmission component. At the same time, the water spraying component is controlled to start the cleaning work. When the cleaning is completed, a signal is sent to control the drying component to start running, and the rock samples in the sample box are dried. When the drying is completed, the electric push rod ejects the sample box, and the loading and unloading component transfers the solid-liquid separation mechanism to the sample stacking mechanism, and this cleaning and drying process is completed. Through the two processes of cleaning and drying, the impurities on the rock samples can be thoroughly removed, and the purity of the rock samples can be maintained, thus eliminating the interference of water and other impurities in the samples and ensuring the accuracy and consistency of the data, providing a more powerful guarantee for subsequent sample inspection and data analysis.

[0023] In a second aspect, the present invention provides an automatic cleaning and collection method for geological rock samples, including the following steps: Step 1, suction sampling process: Using the suction sampling mechanism to extract the mud in the mud conveying pipeline and send it into the solid-liquid separation mechanism; Step 2, solid-liquid separation process: Using the solid-liquid separation mechanism to perform solid-liquid separation on the mud output by the suction sampling mechanism to obtain rock debris samples; Step 3, sample weighing process: Using the sample weighing mechanism to weigh the rock debris samples obtained by solid-liquid separation; Step 4, rock sample transfer process: Using the sample conveying mechanism to convey the weighed rock debris samples from the sample weighing mechanism to the cleaning and drying mechanism; Step 5, cleaning and drying process: Using the cleaning and drying mechanism to perform cleaning and drying treatments on the input rock debris samples; Step 6, buffer transfer process: Using the sample stacking mechanism to buffer and transfer the rock debris samples after cleaning and drying treatments to the sample inspection station.

[0024] Through the above method process, not only can the transformation from mud liquid to quantitative rock debris samples be achieved in a short time, but also the working efficiency of the automatic cleaning and collection of geological rock samples can be significantly improved, the mistakes of manual operations can be reduced, and the labor intensity can be lowered. Moreover, through cleaning and drying treatments, the impurities on the rock samples can be thoroughly removed, and the purity of the rock samples can be maintained, ensuring the accuracy and consistency of the inspection data of geological rock samples.

[0025] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention can achieve fully automated cleaning and collection of cuttings samples from mud, greatly reducing manual operations, shortening the time for collecting and processing cuttings, and improving the work efficiency of cuttings sample collection.

[0026] 2. The present invention is equipped with a weighing device, which can precisely control the weighing process, achieve quantitative collection of samples, reduce the errors in manual collection, and ensure the accuracy and consistency of the data for cuttings sample collection.

[0027] 3.

[0030] The present invention will be further described below with reference to the accompanying drawings through specific embodiments, but the present invention is not limited thereto. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.

[0031] Embodiment 1: As Figures 1 to 13 shown, this embodiment provides an automatic cleaning and collection system for geological rock samples, including a suction sampling mechanism 1, a solid-liquid separation mechanism 2, a sample weighing mechanism 3, a sample conveying mechanism 4, a cleaning and drying mechanism 5, and a sample stacking mechanism 6, wherein: The suction sampling mechanism 1 is used to pump out the mud in the mud conveying pipeline 7 and send it into the solid-liquid separation mechanism 2; The solid-liquid separation mechanism 2 is used to perform solid-liquid separation on the mud to obtain rock debris samples; The sample weighing mechanism 3 is used to weigh the rock debris samples obtained by solid-liquid separation; The sample conveying mechanism 4 is used to convey a certain mass of rock debris samples from the sample weighing mechanism 3 to the cleaning and drying mechanism 5; The cleaning and drying mechanism 5 is used to clean and dry the rock debris samples; The sample stacking mechanism 6 is used to cache and transfer the rock debris samples output by the cleaning and drying mechanism 5.

[0032] When the system automatically cleans and collects geological rock samples, the mud in the mud conveying pipeline 7 is pumped by the sampling mechanism 1 and then sent into the solid-liquid separation mechanism 2 for solid / liquid separation first. The solid-liquid separation process is the core of the entire mud treatment process, and its task is to efficiently separate the mud into two parts: cuttings and waste liquid. The cuttings obtained by the solid-liquid separation mechanism 2 through solid-liquid separation are filtered and collected by the collection device, i.e., the sample box. The separated waste liquid is discharged into the waste liquid collection tank and discharged or reused after simple treatment. Then, the sample weighing mechanism 3 weighs the collected cuttings samples in real time to control the mass of the cuttings samples contained in each sample box. When the sample box reaches the set weight, the sampling mechanism 1 will stop sampling, and at the same time, the sample box filled with cuttings will be sent into the sample conveying mechanism 4 to transfer and temporarily store the sample box filled with cuttings until the sample box is sent into the cleaning and drying mechanism 5 for further processing. After that, the cleaning and drying mechanism 5 cleans and dries the cuttings samples in the sample box. Finally, the sample stacking mechanism 6 transfers and temporarily stores the sample box filled with cuttings. Thus, the system realizes the full-automatic cleaning and collection from mud to cuttings samples. Through the organic cooperation of the above various structures, the transformation from mud liquid to quantitative cuttings samples is achieved in a short time, greatly reducing manual operation, shortening the time for collecting and processing cuttings, and improving work efficiency. At the same time, during the cleaning and collection process, the weighing process can be accurately controlled to achieve quantitative collection of samples, reduce human errors, and ensure the accuracy and consistency of data.

[0033] During the implementation of the present invention, the sampling mechanism 1 includes a mud suction pipe 101, a control valve 102, a suction pump 103, and a funnel 104. The inlet end of the mud suction pipe 101 is communicated with the mud conveying pipeline 7. The control valve 102 and the suction pump 103 are arranged on the mud suction pipe 101. The outlet end of the mud suction pipe 101 is connected with a funnel 104, and this funnel 104 is located above the inlet end of the solid-liquid separation mechanism 2.

[0034] When cleaning and collecting rock samples, the mud in the mud conveying pipeline 7 first arrives at the control valve 102. After the control system of the system determines that rock sample sampling is required, the control valve 102 is opened, and at the same time, the suction pump 103 is started synchronously. Finally, it flows out through the tapered outlet of the funnel 104 and enters the solid-liquid separation mechanism 2 under the action of gravity, the pressure of the subsequent fluid, and inertia, realizing the sampling of the mud; otherwise, the control valve 102 is closed, and the mud bypasses the system and is directly treated and discharged.

[0035] Furthermore, a valve support 105 is supported at the bottom of the control valve 102, and a pump support 106 is supported at the bottom of the suction pump 103.

[0036] By providing the valve support 105 and the pump support 106, the heights of the control valve 102 and the suction pump 103 can be adapted to the mud suction pipe 101, thereby reducing the implementation difficulty of the device.

[0037] As a preferred embodiment, the solid-liquid separation mechanism 2 uses a sample box with water filtering holes.

[0038] Through the filter screen around the sample box, under the action of gravity, the pressure and inertia of the subsequent fluid, the solid-liquid separation of the mud is realized. The solid-phase particles (cuttings) are intercepted in the sample box, while the liquid phase (waste liquid) passes through the filter screen and flows out from the lower opening. With such a design, not only is it convenient and fast, but also the solid-liquid separation of the mud is realized without power. Moreover, the solid-liquid separation mechanism 2 formed by the sample box can also flow between various processes of the system under the action of the sample conveying mechanism 4 and the sample stacking mechanism 6, enabling the sample box to be recycled and achieving lower costs.

[0039] See attached Figure 6 - attached Figure 9 , the sample weighing mechanism 3 includes a weighing support 301, a weighing frame 302, a weighing conveying component 303, a weighing plate 304, a weighing sensor 305, a drain port 306, a rotating motor 307 and a paddle 308. The weighing support 301 is fixedly connected to the bottom of the weighing frame 302. The weighing conveying component 303 is embedded in the weighing frame 302 to realize the conveying connection between the sample weighing mechanism 3 and the sample conveying mechanism 4. The rotating motor 307 is fixed at the center of the bottom of the weighing frame 302. The output shaft of the rotating motor 307 extends upward into the weighing frame 302 and is rotatably connected to the paddle 308. A weighing plate 304 is arranged in the weighing frame 302 below the paddle 308. The bottom of the weighing plate 304 is connected to the weighing frame 302 through a plurality of weighing sensors 305. A drain port 306 is opened on the weighing frame 302 beside the weighing plate 304.

[0040] During the solid-liquid separation process of the rock sample, the solid-liquid separation mechanism 2 is always placed on the weighing plate 304 to realize real-time weighing of the collected cuttings through the weighing sensor 305. The liquid formed after solid-liquid separation is discharged from the sample weighing mechanism through the drain port 306. After the sample box, i.e., the solid-liquid separation mechanism 2, reaches the set weight, the sampling mechanism 1 will be controlled to stop sampling, and then the rotating motor 307 will be controlled to rotate to drive the paddle 308 to rotate a certain angle, so as to send the sample box, i.e., the solid-liquid separation mechanism 2, into the sample conveying mechanism 4 to convey the sample box to the cleaning and drying mechanism 5 for further processing. During the implementation process, in order to control the mass of cuttings in each sample box, the weighing process is not completed at one time, but is divided into twenty times to ensure that the error is within five percent, thereby ensuring the accuracy and consistency of the data.

[0041] Preferably, the cross-section of the paddle 308 is cross-shaped, and two weighing and conveying components 303 are symmetrically arranged with the paddle 308 as the center. The weighing plate 304 and the weighing sensor 305 are arranged near the end of any one of the weighing and conveying components 303.

[0042] Through the above settings, the sample weighing mechanism 3 can cooperate with the two sample conveying mechanisms 4, so as to speed up the rhythm of solid-liquid separation and weighing, improve the working efficiency of the system, and at the same time, more sample boxes can be stored through the setting of the two sample conveying mechanisms 4.

[0043] See attached Figure 10 - attached Figure 12 As shown in the attached figure, the sample conveying mechanisms 4 are symmetrically arranged on both sides of the sample weighing mechanism 3. The inlet of the sample conveying mechanism 4 corresponds to the outlet of the weighing and conveying component 303, so as to alternately perform the caching and transfer of the solid-liquid separation mechanism 2, speed up the rhythm of solid-liquid separation and weighing, and improve the working efficiency of the system. Its specific structure includes a conveying support 401, a conveying frame 402, a conveying drive assembly 403 and a conveying steering assembly 404. The bottoms of the plurality of conveying frames 402 are respectively connected to the tops of the plurality of conveying supports 401 in one-to-one correspondence. A conveying drive assembly 403 is arranged in each conveying frame 402, and the conveying steering assembly 404 is arranged on the conveying frame 402 between adjacent conveying drive assemblies 403. The plurality of conveying drive assemblies 403 and the conveying steering assembly 404 are connected to form an S-shaped sample conveying mechanism 4.

[0044] Based on the above design, the solid-liquid separation mechanism 2 moves in the conveying frame 402 under the action of the conveying drive assembly 403 and the conveying steering assembly 404, so as to realize the caching and transfer of the solid-liquid separation mechanism 2 output by the sample weighing mechanism 3 to the cleaning and drying mechanism 5. At the same time, through the setting of the conveying steering assembly 404, the adjacent conveying drive assemblies 403 are connected, so as to achieve the dual functions of changing the conveying direction of the solid-liquid separation mechanism 2 and increasing the storage capacity of the sample conveying mechanism 4.

[0045] Preferably, the conveying steering assembly 404 includes a steering bracket 40401, a steering support 40402, a steering motor 40403, a steering wheel 40404, a driven wheel 40405, and a transmission belt 40406. The steering support 40402 is fixed to the top of the steering bracket 40401 and fixedly connected to the conveying bracket 401. The steering motor 40403 is fixed on the steering support 40402. The upper steering wheel 40404 is arranged on the output shaft of the steering motor 40403. The driven wheel 40405 is arranged on the conveying frame 402 between adjacent conveying transmission assemblies 403. The steering wheel 40404 and the driven wheel 40405 are connected via a transmission belt 40406.

[0046] Based on the above-mentioned conveying steering assembly 404, the steering wheel 40404, the driven wheel 40405, and the transmission belt 40406 constitute a transmission structure. The rotation of the steering motor 40403 can drive the rotation of the driven wheel 40405, thereby realizing the conveying of the solid-liquid separation mechanism 2.

[0047] See attached Figure 13 With attached Figure 14 The cleaning and drying mechanism 5 comprises a cleaning and drying bracket 501, on which a cleaning housing 502 and a cleaning motor 503 are mounted, a carrying plate 5011 and an adsorption fixing assembly 507 located above the carrying plate 5011 are arranged in the cleaning housing 502, a rotating shaft 505 is connected to the bottom of the carrying plate 5011, and the rotating shaft 505 extends downwardly out of the cleaning housing 502, the output shaft of the cleaning motor 503 is connected to the rotating shaft 505 through a cleaning transmission assembly 504, and a cleaning device 507 is provided on the side of the rotating shaft 505. A plurality of electric push rods 5012 are provided at the inner bottom of the cleaning shell 502. The telescopic ends of the plurality of electric push rods 5012 are naturally located below the supporting plate 5011. When the telescopic ends of the plurality of electric push rods 5012 are extended, they can pass through the supporting plate 5011 and be connected to the bottom of the adsorption fixing component 507. A water spraying component 508 and a drying component 509 are also provided in the cleaning shell 502. A water outlet 5010 is provided at the bottom of the cleaning shell 502. An inclination sensor 506 for detecting the inclination of the rotating shaft 505 is also provided.

[0048] When the cleaning and drying mechanism 5 cleans and dries the solid-liquid separation mechanism 2 conveyed by the sample conveying mechanism 4, first, the electric push rod 5012 ejects the adsorption and fixation component 507. Then, the solid-liquid separation mechanism 2 is grabbed from the sample conveying mechanism 3 and placed on the adsorption and fixation component 507 by the loading and unloading component 5013. The solid-liquid separation mechanism 2 is adsorbed and fixed by the adsorption and fixation component 507. After that, the electric push rod 5012 retracts, and the adsorption and fixation component 507 and the supporting plate 5011 are adsorbed and combined into one body. The cleaning motor 503 is controlled to drive the rotating shaft 505 to rotate through the cleaning transmission component 504. The rotation of the rotating shaft 505 drives the adsorption and fixation component 507, the supporting plate 5011, and the solid-liquid separation mechanism 2 fixed on the adsorption and fixation component 507 to rotate synchronously. At the same time, the water spraying component 508 is controlled to start the cleaning work, and the waste water generated by the cleaning is discharged from the water outlet 5010. When the cleaning is completed, a signal is sent to control the drying component 509 to start running, and the rock sample in the solid-liquid separation mechanism 2 is dried. When the drying is completed, the electric push rod 5012 ejects the solid-liquid separation mechanism 2, and then the loading and unloading component 5013 is used to transfer the solid-liquid separation mechanism 2 to the sample stacking mechanism 6, and this cleaning and drying is completed. Through the two processes of cleaning and drying, the impurities on the rock sample can be thoroughly removed, and the purity of the rock sample can be maintained, thus eliminating the interference of water and other impurities in the sample and ensuring the accuracy and consistency of the data, providing a more powerful guarantee for the subsequent sample inspection and data analysis.

[0049] In the specific implementation process, the water spraying component 508 and the drying component 509 can either be integrally arranged in the cleaning housing 502, or only the water nozzle and the air nozzle are arranged in the cleaning housing 502, while the water pump spraying device and the hot air generating device are arranged outside the cleaning housing 502. The water spraying component 508 and the drying component 509 can both adopt the spraying and air heating devices in the prior art, so the water spraying component 508 and the drying component 509 are not limited in this embodiment.

[0050] In this example, the structures of the sample stacking mechanism 6 and the sample conveying mechanism 4 are the same. Such a choice can effectively reduce the implementation cost and management difficulty.

[0051] In this example, the loading and unloading component 5013 can adopt an existing manipulator, or can also adopt the structure as shown in Figure 13 and Figure 14 which includes a lifting member, a rotating member, a telescopic member, and a clamping member. The bottom of the lifting member is fixed on the cleaning and drying support 501. The top of the lifting member is connected to the fixed end of the rotating member and the telescopic member through the rotating member. The telescopic end of the telescopic member is connected to the fixed end of the clamping member. The clamping end of the clamping member is used to clamp the solid-liquid separation mechanism 2.

[0052] When loading and unloading are required before and after cleaning and drying, first control the lifting member to lift upward, then control the rotating member to drive the telescopic member to rotate, and then control the telescopic member to extend and retract, so that the clamping member is located directly above the solid-liquid separation mechanism 2. Then, control the clamping member to clamp the solid-liquid separation mechanism 2, and finally control the lifting member, rotating member, and telescopic member to transfer the solid-liquid separation mechanism 2 to the adsorption and fixation component 507 or the sample stacking mechanism 6, realizing the loading and unloading of the solid-liquid separation mechanism 2. Based on the above-mentioned loading and unloading component 5013, the automatic loading and unloading of the cleaning and drying mechanism 5 can be realized, which helps to realize the full-automatic sample cleaning and collection of the system.

[0053] During the cleaning process, in order to prevent the cleaning liquid or sample from flying out of the solid-liquid separation mechanism 2, the cleaning and drying mechanism 5 further includes a splash-proof cover 5014 and a switch driving component 5015. The switch driving component 5015 is fixed on the outer wall of the cleaning housing 502. One side of the splash-proof cover 5014 is connected to the driving end of the switch driving component 5015. Under the driving action of the switch driving component 50151, the splash-proof cover 5014 can be rotated so that the splash-proof cover 5014 can cover or open the top opening of the cleaning housing 502.

[0054] Through the setting of the splash-proof cover 5014 and the switch driving component 5015, not only can it prevent the cleaning liquid or sample from flying out of the solid-liquid separation mechanism 2 during the rotary cleaning process, but also the automatic opening and closing of the splash-proof cover 5014 can be realized, so that it can cooperate with the loading and unloading component 5013 to realize the automatic loading and unloading of the cleaning and drying mechanism 5.

[0055] Furthermore, the cleaning and drying mechanism 5 further includes a sleeve 5016. The sleeve 5016 is fixed on the inner surface of the splash-proof cover 5014. When the splash-proof cover 5014 covers the top opening of the cleaning housing 502 under the drive of the switch driving component 50151, the sleeve 5016 covers the upper part of the solid-liquid separation mechanism 2, and there is no contact between the sleeve 5016 and the solid-liquid separation mechanism 2, avoiding interference between the solid-liquid separation mechanism 2 and the sleeve 5016 during the rotary cleaning process.

[0056] Based on the setting of the sleeve 5016, it can further prevent the cleaning liquid or sample from flying out of the solid-liquid separation mechanism 2 during the rotary cleaning process.

[0057] Embodiment 2: This embodiment proposes a cleaning and collection method based on the geological rock sample automatic cleaning and collection system described in Embodiment 1, including the following steps: Step 1, the sampling process by suction: Use the sampling mechanism by suction 1 to extract the mud in the mud conveying pipeline 7; specifically: In this step, the mud in the mud conveying pipeline 7 first arrives at the control valve 102. After the control system of this system determines that rock sample suction sampling is required, the control valve 102 is opened, and at the same time, the suction pump 103 is started synchronously to pump the mud and send it to the funnel 104. Finally, it flows out through the tapered outlet of the funnel 104 and enters the solid-liquid separation mechanism 2 to realize the suction sampling of the mud; otherwise, the control valve 102 is closed, and the mud bypasses this system and is directly processed and discharged.

[0058] Step 2, Solid-liquid separation process: Use the solid-liquid separation mechanism 2 to perform solid-liquid separation on the mud output by the suction sampling mechanism 1 to obtain rock debris samples; specifically: When performing solid-liquid separation, the solid-liquid separation mechanism 2 is placed on the weighing plate 304 of the sample weighing mechanism 3. The mud entering the solid-liquid separation mechanism 2 (sample box with filter screen) realizes the solid-liquid separation of the mud under the action of gravity, the pressure of the subsequent fluid, and inertia. The solid-phase particles (rock debris) are intercepted in the solid-liquid separation mechanism 2, while the liquid phase (waste liquid) passes through the filter screen and flows out from the lower opening.

[0059] Step 3, Sample weighing process: Use the sample weighing mechanism 3 to weigh the rock debris samples obtained by solid-liquid separation; specifically: Since the solid-liquid separation mechanism 2 is always placed on the weighing plate 304 during the solid-liquid separation process, the solid-liquid separation mechanism 2 containing the rock debris samples can be continuously weighed in real time through the weighing sensor 305. The liquid phase (waste liquid) generated by solid-liquid separation passes through the filter screen and flows out from the lower drain port 306; when the solid-liquid separation mechanism 2 containing the rock debris samples reaches the set weight (that is, the rock debris samples reach the set weight), control the suction sampling mechanism 1 to stop sampling, and then control the rotation motor 307 to rotate and drive the dial 308 to rotate a certain angle to drive the dial 308 to dial the solid-liquid separation mechanism 2 away from the weighing position and send it into the sample conveying mechanism 4 through the weighing conveying component 303 to convey the solid-liquid separation mechanism 2 to the cleaning and drying mechanism 5 for further processing. At the same time, a new solid-liquid separation mechanism 2 is input through the weighing conveying component 303 or manually to wait for the next suction sampling instruction.

[0060] Step 4, Rock sample transfer process: Use the sample conveying mechanism 4 to convey the weighed rock debris samples from the sample weighing mechanism 3 to the cleaning and drying mechanism 5; specifically: After the solid-liquid separation mechanism 2 enters the sample conveying mechanism 4, it moves within the conveying frame 402 under the relay conveying action of the conveying transmission component 403 and the conveying steering component 404, and is transferred to the cleaning and drying mechanism 5 after passing through multiple conveying transmission components 403 and conveying steering components 404. Step 5, Cleaning and drying process: Use the cleaning and drying mechanism 5 to clean and dry the input rock debris samples; specifically: After the solid-liquid separation mechanism 2 is transported to the cleaning and drying mechanism 5 by the sample conveying mechanism 4, first, the switch driving component 5015 drives the splash-proof cover 5014 to rotate to open the cleaning outer shell 502. Then, the electric push rod 5012 ejects the adsorption and fixation component 507. Next, the loading and unloading component 5013 transfers the solid-liquid separation mechanism 2 from the sample conveying mechanism 4 to the adsorption and fixation component 507 of the cleaning and drying mechanism 5, and the adsorption and fixation component 507 adsorbs and fixes the solid-liquid separation mechanism 2. After that, the electric push rod 5012 retracts, and the adsorption and fixation component 507 naturally drops and adsorbs and combines with the supporting plate 5011 to form a whole; The control switch driving component 5015 drives the splash-proof cover 5014 to rotate to close the cleaning outer shell 502. Then, the control cleaning motor 503 drives the rotating shaft 505 to rotate through the cleaning transmission component 504. The rotation of the rotating shaft 505 drives the adsorption and fixation component 507, the supporting plate 5011, and the solid-liquid separation mechanism 2 fixed on the adsorption and fixation component 507 to rotate synchronously. At the same time, the control water spraying component 508 starts the cleaning work; After the cleaning is completed, a signal is sent to control the drying component 509 to start running, and the rock sample in the solid-liquid separation mechanism 2 is dried. After the drying is completed, the electric push rod 5012 ejects the solid-liquid separation mechanism 2. Then, the switch driving component 5015 drives the splash-proof cover 5014 to rotate to open the cleaning outer shell 502. Finally, the loading and unloading component 5013 transfers the solid-liquid separation mechanism 2 to the sample stacking mechanism 6, and this cleaning and drying is completed. The waste water generated by the cleaning is discharged from the water outlet 5010.

[0061] Step 6, Buffer transfer process: Use the sample stacking mechanism 6 to buffer and / or transfer the cuttings samples after cleaning and drying to the sample inspection station.

[0062] Based on the above method process, not only can the transformation from slurry to quantitative cuttings samples be achieved in a short time, but also the working efficiency of the automatic cleaning of geological rock samples can be significantly improved, the mistakes of manual operations can be reduced, and the labor intensity can be lowered. Moreover, through cleaning and drying treatments, the impurities on the rock samples can be completely removed, the purity of the rock samples can be maintained, and the accuracy and consistency of the inspection data of geological rock samples can be ensured.

[0063] In summary, the present invention can not only achieve fully automated cleaning and collection of mud to cuttings samples, greatly reducing manual operations, shortening the time for collecting and processing cuttings, and improving the work efficiency of cuttings sample collection. At the same time, through the setting of the sample weighing mechanism 3, the weighing process can be accurately controlled to achieve quantitative collection of samples, reducing the errors in manual collection and ensuring the accuracy and consistency of the data collected for cuttings samples. In addition, by controlling the control valve 102 in the suction sampling mechanism 1, timed collection of cuttings samples can be achieved, ensuring the timely acquisition of cuttings samples, systematically and continuously accumulating cuttings data, and providing a more comprehensive and systematic basis for subsequent data analysis and interpretation.

Specific examples are used herein to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention.
