Description

Technical Field

[0001] The present invention mainly relates to the field of coal sampling equipment, in particular to a vehicle-mounted sampling device and an automated sampling vehicle. Background Art

[0002] Ports, power plants, and mining and smelting companies purchase large quantities of lump or powdered mineral resources, such as commercial coal, as raw materials during their production processes. This bulk coal is primarily transported by train or heavy truck.

[0003] Commercial coal samples are coal samples that represent the average quality of commercial coal. Based on their test results, both the supplier and the buyer can understand the quality of the coal shipped or received, and use this as the basis for settlement and handling quality disputes between the two parties. Therefore, the collection of commercial coal samples is the most fundamental step in obtaining reliable quality data. For a long time, surface sampling on trains has been done manually using a sampling shovel to collect samples and place them in sample bags. This has the following technical problems:

[0004] First, the working environment is harsh. Existing train surface sampling requires workers to work outdoors, exposed to the sun and rain, and exposed to dust and noise for a long time. The working environment is harsh and the chance of contracting occupational diseases is also high.

[0005] Second, the labor intensity is high and the operation efficiency is low: using traditional tools for manual sampling is inefficient and labor-intensive. Furthermore, because multiple carriages are required for continuous sampling, multiple bags of samples must be collected continuously. This not only makes the sample collection process inefficient, but also the bagging process after collection is inefficient. The bagging process is prone to dust, which not only pollutes the environment but also makes the outside of the sample bags covered with coal dust, making it difficult to transport and prepare samples for testing.

[0006] Third, there is a lot of human interference. Samples are randomly taken in the train carriage by manual sampling shovels. The sampling volume is insufficient, and the different positions, angles, depths, and qualities of the sub-sampling points result in poor representativeness of the collected samples, which greatly affects the fairness and justice of coal trade.

[0007] Fourth, there are great safety hazards. It is necessary to walk on the side of a train or on a sampling vehicle to take samples. Especially when sampling at night, in rainy and snowy days, and in severe winter seasons, there are great safety hazards.

[0008] Fifth, existing sampling workshops often have various overhead pipes and facilities, making the space above train cars very narrow. This makes it difficult to stand on the trains for sampling, or to use large gantry trucks for sampling from above. Furthermore, using large train-mounted sampling equipment is expensive and takes up a lot of space, significantly increasing operating costs. Summary of the Invention

[0009] The technical problem to be solved by the present invention is to overcome the shortcomings of the existing technology and provide a vehicle-mounted sampling device with a simple and compact structure, easy to manufacture and maintain, high degree of automation, greatly reduced labor intensity and work costs, greatly improved labor efficiency, and safe and environmentally friendly. An automated sampling vehicle is also provided.

[0010] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0011] A vehicle-mounted sampling device for collecting materials in a vehicle compartment, comprising a lifting arm assembly for vertical installation on a mobile vehicle, the lifting arm assembly being provided with a transversely arranged telescopic arm assembly, the telescopic end of the telescopic arm assembly being provided with a bucket assembly, the telescopic arm assembly also being provided with a receiving hopper assembly, the telescopic arm assembly being used to extend the bucket assembly into the vehicle compartment for sampling and then retract it so that the retracted bucket assembly is above the receiving hopper assembly for unloading, the lifting arm assembly being used to drive the telescopic arm assembly downward so that the extended bucket assembly is placed on a sampling point for sampling, and to drive the telescopic arm assembly upward after sampling so that the bucket assembly can be retracted from the vehicle compartment to above the receiving hopper assembly.

[0012] As a further improvement of the present invention, the telescopic arm assembly includes a boom and a forearm, the boom is installed on the lifting arm assembly, the forearm is telescopically limited and installed on the boom, the bucket assembly is installed on the forearm, and a telescopic drive cylinder is provided on the boom along the telescopic direction, and the drive shaft end of the telescopic drive cylinder is connected to the forearm for driving the forearm to telescope on the boom.

[0013] As a further improvement of the present invention, the bucket assembly includes a bucket, a bucket drive cylinder, a connecting rod and a rocker arm. The bucket is hingedly mounted on the forearm, one end of the rocker arm is hinged to the bucket, and the other end is hinged to the connecting rod. The other end of the connecting rod is hingedly mounted on the forearm, and the hinge between the rocker arm and the bucket is also hinged to the drive shaft end of the bucket drive cylinder, so that when the bucket drive cylinder is telescopically driven, the bucket is driven by the rocker arm and the connecting rod to achieve excavation, shoveling or unloading operations.

[0014] As a further improvement of the present invention, the forearm limit sleeve is arranged in the upper arm, a movable groove is opened on the upper arm along the telescopic direction, a protruding mounting seat is provided in the movable groove on the forearm, and the tail end of the bucket drive cylinder is installed on the forearm through the mounting seat.

[0015] As a further improvement of the present invention, the receiving hopper assembly includes a hopper, a mounting plate and multiple connecting parts. The tail end of the mounting plate is used to be fixed on the telescopic arm assembly. The head end of the mounting plate is provided with two protruding mounting rods. The hopper is suspended below the mounting rods through multiple vertical connecting parts. An accommodating space is formed between the two mounting rods to allow the retracted bucket assembly to be in the accommodating space above the hopper for unloading.

[0016] As a further improvement of the present invention, the connecting member is an elastic member so that the hopper is flexibly suspended on the mounting plate.

[0017] As a further improvement of the present invention, the lifting arm assembly includes a main arm and a lifting drive cylinder, the telescopic arm assembly is hingedly mounted on the main arm through a rotating shaft, the tail end of the lifting drive cylinder is mounted on the main arm, and the drive shaft end is hingedly mounted to the telescopic arm assembly for lifting or lowering the telescopic arm assembly by telescopically driving the telescopic arm assembly with the rotating shaft as a fulcrum.

[0018] As a further improvement of the present invention, the bottom of the lifting arm assembly is installed on the mobile vehicle through a slewing mechanism, and the slewing mechanism is used to drive the lifting arm assembly to rotate so that the bucket assembly can take samples at different sampling points in the compartment.

[0019] As a further improvement of the present invention, a material receiving and sealing mechanism is provided, which includes a matching material receiving box and a bag frame. The top opening of the material receiving box is connected to the discharge port of the material receiving hopper assembly through a connecting pipe. The material receiving box is provided with a side opening for the bag frame to enter and dock with the top opening. The bag frame is hollow so that the sample bag can be installed in the bag frame and enter and exit the material receiving box together with the bag frame. A sealing assembly is provided below the top opening in the material receiving box, which is used to form a sealed connection between the top opening and the sample bag after the bag frame enters before receiving the material.

[0020] As a further improvement of the present invention, the top of the bagging frame is provided with a rim portion so that the top of the sample bag installed in the bagging frame extends from the rim portion and then folds outward. The sealing assembly includes a sealing plate, which is fixed to the top plate of the receiving box by a plurality of elastic fixing parts and can be squeezed up and down. A circle of upwardly protruding first sealing edges is provided at the middle opening of the sealing plate for forming a connection with the top opening portion. When the bagging frame enters the receiving box and squeezes the sealing plate upward, the sealing plate is pressed downward on the rim portion to form a sealed connection, so that the sample transmitted from the connecting tube enters the sample bag through the top opening and the middle opening in sequence.

[0021] As a further improvement of the present invention, each of the elastic fixing parts includes a limiting rod fixed vertically downward on the top plate of the material receiving box. The lower end of the limiting rod passes through the sealing plate and is limited so that the sealing plate can only move up and down along the limiting rod.

[0022] As a further improvement of the present invention, the sealing plate is further provided with two or more upwardly arranged guide rods, and the top plate of the material receiving box is further provided with two or more linear bearings cooperating with the guide rods. The guide rods pass upward through the top plate of the material receiving box and are connected to the linear bearings to form a limit for the sealing plate moving up and down.

[0023] As a further improvement of the present invention, a circle of connecting pipe portions is provided at the top opening portion for connecting to the connecting pipe, and a circle of sealing pipe portions is nested outside the connecting pipe portion to form a circle of slot portions between the connecting pipe portion and the sealing pipe portion. The top end of the slot portion is sealed, and the bottom end opening is used to allow the first sealing edge to movably extend into the slot portion.

[0024] As a further improvement of the present invention, a plurality of movable wheels are provided at the bottom of the bagging frame, and a guide edge is provided at one end of the sealing plate close to the side opening, so as to first contact the bagging frame and form a guide when the bagging frame is pushed in.

[0025] An automated sampling vehicle comprises a movable vehicle body, on which any vehicle-mounted sampling device as described above is mounted.

[0026] As a further improvement of the present invention, an operating table and a control cabinet are also installed on the vehicle body.

[0027] Compared with the prior art, the advantages of the present invention are:

[0028] First, automated sampling completely eliminates the existing practice of manually standing on the surface of train carriages to collect samples. Workers no longer have to work outdoors, exposed to the sun and rain, or exposed to dust and noise for extended periods. This creates a better working environment and reduces the risk of occupational diseases. This significantly reduces labor intensity and improves efficiency.

[0029] Secondly, mechanical and automated sampling greatly reduces the risk of human interference, and through the movement of the mobile vehicle and the different telescopic lengths of the telescopic arm assembly, samples can be taken from multiple different locations in the carriage, resulting in a larger sampling volume. More importantly, due to the coordination of the different lifting heights of the lifting arm assembly and the different telescopic lengths of the telescopic arm assembly, the bucket assembly can adapt to coal samples of different heights in the train carriage (the coal samples in the carriage are not necessarily all flat), that is, the bucket assembly can not only select samples of different depths (by lifting and lowering), but also mechanical sampling can collect samples of different qualities (manual sampling can only collect shallower and lighter samples due to limited strength). Therefore, the representativeness of the samples collected by this device is more comprehensive, which greatly ensures the comprehensiveness and accuracy of the subsequent test results, and greatly improves the fairness and justice of coal trade.

[0030] Third, it's safe and environmentally friendly. Workers no longer need to walk on the side of a train or on a sampling vehicle to collect samples, significantly reducing safety hazards. Furthermore, the unique combination of the telescopic arm assembly, bucket assembly, and hopper assembly allows for direct and rapid sample collection through the hopper assembly and pipeline. This significantly reduces dust and avoids environmental pollution. Furthermore, the outside of the sample bag is protected from coal dust, making subsequent transportation and sample preparation and testing extremely convenient.

[0031] Fourth, it offers better adaptability. In existing sampling workshops, some have various pipes and facilities installed overhead, meaning the space above train cars is very narrow, making it inconvenient for people to stand on the cars to take samples, or to use large truss trucks to take samples from above. However, using this device, the bucket assembly can be lowered to a certain height to allow it to extend into the car to complete sampling and return to unload, greatly improving adaptability. Furthermore, this device has a simple and compact structure, takes up little space, and can be quickly deployed on existing mobile vehicles such as pickup trucks. The low equipment cost significantly reduces the company's operating costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] like Figures 1 to 16 As shown, the present invention provides a vehicle-mounted sampling device for collecting materials in a vehicle compartment, such as Figure 1 、 Figure 5 、 Figure 6 The train carriage E shown in FIG. comprises a lifting arm assembly 1 for vertical installation on a moving vehicle, the height of the lifting arm assembly 1 is between 0.5 meters and 10 meters, and a fixing assembly is provided at the bottom of the lifting arm assembly 1 for fixed installation on the moving vehicle. In this embodiment, the moving vehicle is as shown in FIG. Figure 1 、 Figure 5 、 Figure 6 The car F shown in . Of course, in other embodiments, the mobile vehicle can also be a rail car installed on one side of the car, or other car body structures, as long as it can drive the vehicle-mounted sampling device to move along the car for sampling. The lifting arm assembly 1 is provided with a transversely arranged telescopic arm assembly 2, and the telescopic end of the telescopic arm assembly 2 is provided with a bucket assembly 3. The telescopic arm assembly 2 is also provided with a receiving hopper assembly 4. The telescopic arm assembly 2 is used to extend the bucket assembly 3 into the car for sampling and then retract it so that the retracted bucket assembly 3 is above the receiving hopper assembly 4 for unloading. The lifting arm assembly 1 is used to drive the telescopic arm assembly 2 to descend so that the extended bucket assembly 3 falls on the sampling point for sampling, and after sampling, drives the telescopic arm assembly 2 to rise so that the bucket assembly 3 can be retracted from the car to above the receiving hopper assembly 4. The specific implementation principle is as follows:

[0052] like Figure 1As shown, when the mobile vehicle drives to the vicinity of the carriage where sampling is required, the lifting arm assembly 1 first drives the telescopic arm assembly 2 to rise, so that the carriage wall does not form an obstacle to the bucket assembly 3 to be extended. Then the telescopic arm assembly 2 is extended into the carriage to extend the bucket assembly 3 to the sampling point in the carriage; then the lifting arm assembly 1 drives the telescopic arm assembly 2 to descend so that the extended bucket assembly 3 falls to the sampling point for sampling; after sampling, the bucket assembly 3 remains in the bucket hook state (as shown in FIG. Figure 9 As shown), the lifting arm assembly 1 drives the telescopic arm assembly 2 to rise again, so that the compartment wall will not hinder the bucket assembly 3 to be retracted. Then the telescopic arm assembly 2 is retracted, and the retracted bucket assembly 3 is returned to the top of the receiving hopper assembly 4 (as shown). Figure 2 As shown), the bucket assembly 3 then turns downward to unload (as shown Figure 10 As shown), all collected samples are tilted into the receiving hopper assembly 4 below.

[0053] When sampling is required at multiple different sampling points within the vehicle compartment, the following methods can be used: first, the mobile vehicle remains stationary, but the telescopic arm assembly 2 is extended to a different length each time, allowing samples to be collected at multiple different points along the width of the vehicle compartment; or after each sampling operation, the mobile vehicle moves forward or backward a certain distance, allowing the telescopic arm assembly 2 to collect samples at multiple different points along the length of the vehicle compartment; or a combination of the above two methods allows for the collection of samples at even more different points. Alternatively, in the embodiment described below, a slewing mechanism 5 is further provided, which is used to drive the lifting arm assembly 1 to rotate so that the bucket assembly 3 can sample at different sampling points within the vehicle compartment.

[0054] Regarding the bucket assembly 3, after collecting the sample, it can cooperate with the material receiving and sealing mechanism 6 on the mobile vehicle to carry out bagging and collection of the sample as described below, or it can directly connect with the collection bucket and collection bag on the ground through a pipeline, so that the sample tilted into the receiving hopper assembly 4 can be quickly bagged. Regarding the control of the lifting arm assembly 1, the telescopic arm assembly 2 and other components, in this embodiment, there is also an operating table and a control cabinet installed on the mobile vehicle. Of course, in other embodiments, a remote-controlled operating table can also be set up in the laboratory to control the components on the mobile vehicle for sampling through wireless communication. For example, multiple cameras are also installed on the mobile vehicle to monitor the operation of each component in real time. When the collection in this car is completed, the mobile vehicle can move forward or backward to the vicinity of the next car to be collected, and then sample the car in the manner described above, with extremely high work efficiency. Through the above special scientific design, it has the following technical advantages:

[0055] First, automated sampling completely eliminates the existing practice of manually standing on the surface of train carriages to collect samples. Workers no longer have to work outdoors, exposed to the sun and rain, or exposed to dust and noise for extended periods. This creates a better working environment and reduces the risk of occupational diseases. This significantly reduces labor intensity and improves efficiency.

[0056] Secondly, mechanical and automated sampling greatly reduces the risk of human interference, and through the movement of the mobile vehicle and the different telescopic lengths of the telescopic arm assembly 2, samples can be taken from multiple different locations in the carriage, resulting in a larger sampling volume. More importantly, due to the different lifting heights of the lifting arm assembly 1 and the different telescopic lengths of the telescopic arm assembly 2, the bucket assembly 3 can adapt to coal samples of different heights in the train carriage (the coal samples in the carriage are not necessarily all flat), that is, the bucket assembly 3 can not only select samples of different depths (by lifting), but also mechanical sampling can collect samples of different qualities (manual sampling can only collect shallower and lighter samples due to limited power). Therefore, the representativeness of the samples collected by this device is more comprehensive, which greatly ensures the comprehensiveness and accuracy of the subsequent test results, and greatly improves the fairness and justice of coal trade.

[0057] Third, it is safe and environmentally friendly. Workers no longer need to walk on the side of a train or on a sampling vehicle to collect samples, greatly reducing safety hazards. Furthermore, the special coordination of the telescopic arm assembly 2, bucket assembly 3, and hopper assembly 4 allows for direct and rapid sample collection through the hopper assembly 4 and pipeline after sampling, significantly reducing dust and avoiding environmental pollution. Furthermore, the outside of the sample bag is protected from coal dust, making subsequent transportation and sample preparation and testing extremely convenient.

[0058] Fourth, it has better adaptability. In existing sampling workshops, some workshops are equipped with various pipes and facilities above the workshops, that is, the space above the train carriages is very narrow, making it inconvenient for people to stand on the carriages to take samples, or to use large truss vehicles to take samples above the carriages. However, if this device is used, the bucket assembly 3 can be extended into the carriage by raising and lowering a certain height to complete sampling and return to unload, which greatly improves the adaptability. In addition, the device has a simple and compact structure, occupies a small space, and can be quickly arranged on existing mobile vehicles such as pickup trucks. The equipment cost is low, which also greatly reduces the operating costs of the enterprise.

[0059] like Figures 1 to 10As shown, in a preferred embodiment, the telescopic boom assembly 2 includes a boom 21 and an arm 22. The boom 21 is mounted on the lifting arm assembly 1, and the arm 22 is telescopically mounted on the boom 21. The bucket assembly 3 is mounted on the arm 22. A telescopic drive cylinder 23 is provided on the boom 21 along the extension and retraction direction. The drive shaft end of the telescopic drive cylinder 23 is connected to the arm 22, which is used to drive the arm 22 to extend and retract on the boom 21. In this embodiment, the telescopic drive cylinder 23 is an oil cylinder mounted on the side of the boom 21. The arm 22 is limited and sleeved within the boom 21. The oil cylinder can be driven to extend or retract the arm 22 from the boom 21. The hopper assembly 4 is also mounted on the boom 21. That is, when the hopper 3 on the arm 22 is extended, it is directly above the hopper assembly 4. Therefore, when the bucket assembly 3 is retracted, it returns to the top of the hopper assembly 4 to complete the unloading.

[0060] Of course, in other embodiments, the telescopic arm assembly 2 may also adopt other structural forms, such as a multi-link structure, where the tail end of the multi-link is fixed to the lifting arm assembly 1, the bucket assembly 3 is mounted at the head end of the multi-link, and the hopper assembly 4 is mounted at the tail end of the multi-link. Such structures shall also fall within the scope of protection of the present invention.

[0061] like Figures 1 to 10 As shown, in a preferred embodiment, the bucket assembly 3 includes a bucket 31, a bucket drive cylinder 32, a connecting rod 33, and a rocker arm 34. The bucket 31 is hingedly mounted on the arm 22. One end of the rocker arm 34 is hingedly connected to the bucket 31, and the other end is hingedly connected to the connecting rod 33. The other end of the connecting rod 33 is hingedly mounted on the arm 22. The hinged connection between the rocker arm 34 and the bucket 31 is also hingedly connected to the drive shaft end of the bucket drive cylinder 32. When the bucket drive cylinder 32 is extended or retracted, the rocker arm 34 and the connecting rod 33 drive the bucket 31 to perform digging, shoveling, or unloading operations. This structural form is not only simple and compact, but also has high structural strength and is easy and flexible to operate. It enables the bucket assembly 3 to stably perform digging and unloading operations on the arm 22. Imagine if the bucket assembly 3 were complex and heavy, this would inevitably affect the load-bearing and extension capacity of the arm 22, making sampling impossible.

[0062] like Figures 1 to 10As shown, further, in a preferred embodiment, the arm 22 is limitedly sleeved in the arm 21, and a movable groove 211 is provided on the arm 21 along the telescopic direction. A protruding mounting seat 35 is provided on the arm 22 in the movable groove 211, and the tail end of the bucket drive cylinder 32 is mounted on the arm 22 through the mounting seat 35. When the arm 22 is retracted, it should be retracted together with the arm 21 as much as possible. This is to minimize the space occupied by the device and to achieve rapid collection operations, so that the receiving hopper assembly 4 can form a short-distance connection with the ground collection device or the receiving sealing mechanism 6 described below without a long transmission pipeline. However, the arm 22 must be provided with a bucket drive cylinder 32 that moves telescopically with the arm 22. To solve this technical problem, the present invention provides a movable groove 211 on the boom 21 along the extension and retraction direction. This allows the bucket drive cylinder 32 mounted on the boom 22 to be free from the restriction of the boom 21 when the arm 22 is extended or retracted. The bucket drive cylinder 32 can flexibly move back and forth within the movable groove 211 of the boom 21 via the mounting base 35. This effectively solves the technical goal of extending the boom 22 as far as possible while overlapping the boom 21 as much as possible when retracting.

[0063] like Figures 1 to 10 As shown, further, in a preferred embodiment, the receiving hopper assembly 4 includes a hopper 41, a mounting plate 42, and multiple connectors 43. The rear end 421 of the mounting plate 42 is used to fix to the telescopic arm assembly 2. The front end of the mounting plate 42 is provided with two extending mounting rods 422. The hopper 41 is suspended below the mounting rods 422 via multiple vertical connectors 43. A receiving space is formed between the two mounting rods 422, allowing the retracted bucket assembly 3 to be placed in the receiving space above the hopper 41 for unloading. This structural form is not only simple and compact, easy to manufacture and maintain, but also effectively solves the technical problem of cooperating between the hopper 41 and the retracted bucket assembly 3 above to receive materials.

[0064] Furthermore, in a preferred embodiment, the connecting member 43 is an elastic member so that the hopper 41 can be flexibly suspended on the mounting plate 42. In this embodiment, the connecting member 43 is a plurality of tension springs. This is a special design. First, it can allow the hopper 41 to have a certain amount of sinking margin during unloading, that is, it forms a certain buffer for the hopper 41, so that the material will not hit the hopper 41 harshly and form accumulation and blockage, making unloading smoother. Second, the hopper 41 is suspended on the mounting plate 42 by tension springs. The hopper 41 can always remain in a vertical state, forming a flexible vertical body, which can better ensure that the sample does not leak during unloading.

[0065] like Figures 1 to 10As shown, further, in a preferred embodiment, the lifting arm assembly 1 includes a main arm 11 and a lifting drive cylinder 12. The telescopic arm assembly 2 is hingedly mounted on the main arm 11 via a rotating shaft 13. The tail end of the lifting drive cylinder 12 is mounted on the main arm 11, and the drive shaft end is hingedly connected to the telescopic arm assembly 2, so as to be used to telescopically drive the telescopic arm assembly 2 to be raised or lowered with the rotating shaft 13 as the fulcrum. Of course, in other embodiments, other lifting mechanisms may also be provided, and are recognized as falling within the scope of protection of the present invention.

[0066] Furthermore, in a preferred embodiment, the bottom of the lifting arm assembly 1 is mounted on the mobile vehicle via a slewing mechanism 5, and the slewing mechanism 5 is used to drive the lifting arm assembly 1 to rotate so that the bucket assembly 3 can take samples at different sampling points in the vehicle. This allows the mobile vehicle to be moved without moving it when different points need to be sampled. The telescopic arm assembly 2 can be moved to different positions for sampling by simply driving the lifting arm assembly 1 to rotate. At the same time, before sampling, the lifting arm assembly 1 can be rotated back and kept in the same direction as the axle of the mobile vehicle, so that the mobile vehicle takes up less space when moving. The mobile vehicle only needs to move to the edge of the vehicle compartment, then drive the lifting arm assembly 1 to rise, and then drive the lifting arm assembly 1 to rotate so that the telescopic arm assembly 2 moves to the vehicle compartment. More importantly, the present invention flexibly suspends the hopper 41 on the mounting plate 42 via a tension spring. A flexible hose is provided between the hopper 41 and the ground collection device or the material receiving and sealing mechanism 6 described below. When the height of the work site is limited, resulting in the height of the lifting arm assembly 1 being limited and the angle between the flexible hose and the horizontal plane being too small, preventing the sample from sliding smoothly down the hose, the lifting arm assembly 1 can rotate a certain angle to adjust the position of the telescopic arm assembly 2 so that the angle between the hose and the horizontal plane satisfies the requirement for smooth sample removal. During this rotational adjustment process, the hopper 41 suspended by the tension spring remains in a vertical position regardless of the angle between the telescopic arm assembly 2 and the horizontal plane, greatly facilitating smooth sample removal.

[0067] like Figure 1 、 Figure 2 、 Figures 11 to 16 As shown, further, in a preferred embodiment, a material receiving and sealing mechanism 6 is also provided, which includes a matching material receiving box 61 and a bag frame 62. The top opening 611 of the material receiving box 61 is connected to the discharge port of the material receiving hopper assembly 4 through a connecting pipe 63. The material receiving box 61 is provided with a side opening 612 for the bag frame 62 to enter and dock with the top opening 611. The bag frame 62 is hollow so that the sample bag can be installed in the bag frame 62 and enter and exit the material receiving box 61 together with the bag frame 62. A sealing component 64 is provided below the top opening 611 in the material receiving box 61, which is used to form a sealed connection between the top opening 611 and the sample bag after the bag frame 62 enters and then receive the material.

[0068] In this embodiment, the material receiving box 61 is also installed on the mobile vehicle. Before sampling, the sample bag (such as Figure 13 The sample bag (A shown in the figure) is installed in the bagging frame 62 and is pushed into the receiving box 61 along with the bagging frame 62. The sealing assembly 64 in the receiving box 61 forms a sealed connection between the top opening 611 and the sample bag. At this point, sampling is carried out, and the sample discharged from the hopper 41 passes through the connecting tube 63, the top opening 611, and the sealing assembly 64, entering the sample bag in the bagging frame 62. When the sample is collected, the bagging frame 62 is pulled out and the sample bag containing the sample is removed for packaging. A new sample bag is then installed in the bagging frame 62 and pushed into the receiving box 61 along with the bagging frame 62 for the next sample collection. This design eliminates the need for manual handling of the sample bag for sample collection. Samples are collected and filled automatically, resulting in high efficiency and low labor intensity. Furthermore, sample bagging does not generate dust or pollute the environment, and the outside of the sample bag is protected from coal dust, greatly facilitating subsequent transportation and sample preparation and analysis.

[0069] like Figures 11 to 16 As shown, further, in a preferred embodiment, a rim portion 621 is provided on the top of the bag frame 62 so that the top of the sample bag installed in the bag frame 62 extends from the rim portion 621 and then folds outward (as shown in FIG. Figure 13 The sealing assembly 64 includes a sealing plate 641, which is fixed to the top plate of the receiving box 61 by a plurality of elastic fixing members 642 and can be squeezed up and down. A circle of upwardly protruding first sealing edges 6412 is provided at the middle opening 6411 of the sealing plate 641 for forming a connection with the top opening portion 611 (the first sealing edge 6412 can be connected to the top opening portion 611 by the nesting method described below, or can be directly connected to the top opening portion 611 by a hose). When the bag frame 62 enters the receiving box 61 and squeezes the sealing plate 641 upward, the sealing plate 641 further squeezes the elastic fixing member 642, and is pressed downward on the rim portion 621 by the rebound action of the elastic fixing member 642 to form a sealed connection, so that the sample transmitted from the connecting pipe 63 enters the sample bag through the top opening portion 611 and the middle opening 6411 in sequence. This ensures that when the samples are bagged, dust will not be generated, the environment will not be polluted, and the outside of the sample bag will not be covered with coal powder, which is extremely convenient for subsequent transportation and sample preparation and testing.

[0070] like Figures 11 to 16As shown, further, in a preferred embodiment, each elastic fixing member 642 includes a limiting rod 6421 fixed vertically downward on the top plate of the material receiving box 61, and the lower end of the limiting rod 6421 passes through the sealing plate 641 and is limited so that the sealing plate 641 can only move up and down along the limiting rod 6421. A compression spring 6422 is provided on the limiting rod 6421 for squeezing the sealing plate 641 moving upward.

[0071] like Figures 11 to 16 As shown, in a preferred embodiment, the sealing plate 641 is further provided with two or more upwardly directed guide rods 6413. The top plate of the receiving box 61 is further provided with two or more linear bearings 616 that cooperate with the guide rods 6413. The guide rods 6413 extend upward through the top plate of the receiving box 61 and connect to the linear bearings 616 to limit the upward and downward movement of the sealing plate 641. This further ensures that the upward and downward movement of the sealing plate 641 is limited, with very precise movement and no left-right displacement, thereby effectively ensuring that the sealing plate 641 is pressed downward against the rim 621 to form a sealed connection.

[0072] like Figures 11 to 16 As shown, further, in a preferred embodiment, a circle of connecting pipes 613 is provided at the top opening 611 for connection to the connecting pipe 63. A circle of sealing pipes 614 is nested outside the connecting pipe 613 to form a circle of slots 615 between the connecting pipe 613 and the sealing pipe 614. The top of the slot 615 is sealed, and the bottom is open for the first sealing edge 6412 to movably extend into the slot 615. This structural form forms a nested maze structure design, allowing the sealing plate 641 to move up and down while always nesting with the connecting pipe 613 and the sealing pipe 614, resulting in excellent sealing performance and preventing leakage and spillage of samples.

[0073] like Figures 11 to 16 As shown, further, in a preferred embodiment, the bottom of the bagging frame 62 is provided with multiple movable wheels 622. This allows the bagging frame 62, and thus the sample bag, to be easily removed even when the sample bag is filled with sample and has a certain weight. The sealing plate 641 has an upwardly inclined guide edge 6414 at one end near the side opening 612, which is used to first contact and guide the bagging frame 62 when the bagging frame 62 is pushed in. This makes it easier to push the bagging frame 62 in, and prevents it from getting stuck with the sealing plate 641.

[0074] like Figure 1 As shown, the present invention also provides an automated sampling vehicle, including a movable vehicle body, for example, a pickup truck body design in the prior art, and any vehicle-mounted sampling device as described above is installed on the vehicle body.

[0075] Furthermore, in a preferred embodiment, an operating table and a control cabinet (such as Figure 1 As shown in Figure B), the operating console is installed in the cockpit, which can operate and control the vehicle-mounted sampling device directly on the vehicle.

[0076] Although the present invention has been disclosed above with reference to preferred embodiments, this is not intended to limit the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, utilize the technical content disclosed above to make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes. Therefore, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the scope of protection of the technical solution of the present invention.
