The present invention inserts the semi-cylinders into the materials after they are away from each other, and then brings the semi-cylinders closer to each other, so that the materials enter a storage tank for sampling, thereby reducing the situation in which the materials flow downwards during the traditional sampling process, thereby causing more upper materials in the sampled materials, which affects the accuracy of subsequent detection, and the semi-cylinders are closer to each other to facilitate the materials to enter the storage tank, avoiding the situation in which the traditional sampling amount is small or even sampling cannot be performed due to the fluidity of the materials themselves entering the sampling mechanism, facilitating actual sampling and use, thereby facilitating subsequent detection and avoiding the reduction of detection efficiency.

Description

Technical Field

[0001] The invention relates to the field of detection technology, and in particular to an automatic sampling detection device and method for automobile transport materials. Background Art

[0002] In places where aggregates such as coal and sand and gravel are supplied, it is necessary to test the coal and sand and gravel to determine that the collected and distributed coal and sand and gravel meet the requirements. The existing technology usually drives a material transport vehicle under the gantry and takes samples through the sampling device on the gantry.

[0003] The disclosure discloses an automatic raw salt sampling device with the publication number CN111929101B. The problem raised in the background technology is as follows: raw salt sampling is carried out by opening the baffle of a vehicle to sample from the fallen salt pile, which usually causes sampling instability and also causes the driver to pile up good quality raw salt in a concentrated manner, while piling up unqualified raw salt in the unsampled area, resulting in unrepresentative raw salt quality sampling; at the same time, a long time for a shovel to load salt will cause delays in the raw salt sampling time, affecting the sampling speed of the salt truck.

[0004] Based on the existing technology, there are the following problems:

[0005] When sampling, existing transport aggregate vehicles usually insert the cylindrical body into the material, and then the material enters the cylindrical body through the fluidity of the material itself. Then, the cylindrical body is lifted up to bring the material out. Since the material usually has fluidity, it is not convenient to sample materials at different depths, which affects the accuracy of subsequent detection. Referring to the above application documents, the outer sleeve is dropped first, and then the inner sleeve is dropped, and then the material automatically flows into the material collection box between the outer sleeve and the inner sleeve. However, sampling materials at different positions through the fluidity of the material itself can easily cause the upper material to flow downward, resulting in the situation that the lower part cannot be collected or is collected less. In addition, the outer sleeve and the inner sleeve are inserted into the material to squeeze the material, which makes the force between the materials larger, affecting the material from entering the material collection box, thereby affecting the actual sampling and use. There are certain shortcomings. In order to solve the above problems, an automatic sampling and detection device and method for automobile transport materials are proposed. Summary of the invention

[0006] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides an automated sampling and detection device and method for automobile transport materials, which reduces the occurrence of downward flow of materials during the traditional sampling process, improves the accuracy of subsequent detection, and avoids the traditional situation in which the material only relies on its own fluidity to enter the sampling mechanism, resulting in a small sampling amount or even no sampling, thereby facilitating subsequent detection.

[0028] Furthermore, the height of the guide plate is greater than the height of the partition plate, so that the inner wall of the guide groove cooperates with the side wall stopper of the guide plate, thereby limiting the separation of the partition plate from the guide groove, and the inner wall of the guide groove on one side close to the material storage trough fits with the side wall of the partition plate to limit the material from entering the guide groove;

[0030] The diameter of the semi-cylinder is greater than the length of the plate.

[0031] The present invention also provides a method for using the automatic sampling and detection device for automobile transport materials. The method adopts the automatic sampling and detection device for automobile transport materials, and comprises the following steps:

[0032] S1: driving the transport vehicle for transporting materials to the bottom of the gantry, and then adjusting the position of the sampling mechanism through the position adjustment mechanism so that the sampling mechanism samples the designated position;

[0033] S2: When the sampling mechanism takes samples, the semi-cylinder and the plate are first moved away from each other by the moving component, and then the semi-cylinder and the plate are inserted into the material. Then, the semi-cylinder and the plate are moved closer to each other by the moving component to clamp the material in the storage tank;

[0034] S3: After the material is clamped in the storage trough, the material in the storage trough is separated by a partition component to collect materials at different heights. Then, the semi-cylinder is moved upward, and the materials at different heights are discharged through a discharge component to complete the sampling of materials at different heights.

[0035] The present invention provides an automatic sampling and detection device and method for automobile transport materials. Compared with the prior art, it has the following beneficial effects:

[0036] 1. The present invention moves the semi-cylinders away from each other and then inserts them into the material, and then moves the semi-cylinders closer to each other, so that the material enters the storage tank for sampling, thereby reducing the situation in which the material flows downward during the traditional sampling process, thereby resulting in more upper material in the sampled material, which affects the accuracy of subsequent detection. The semi-cylinders are closer to each other to facilitate the material to enter the storage tank, avoiding the traditional situation in which the material enters the sampling mechanism only by the fluidity of the material itself, resulting in a small sampling amount or even no sampling. The actual sampling is convenient for use, thereby facilitating subsequent detection and avoiding a reduction in detection efficiency.

[0037] 2. The present invention clamps the material by bringing the semi-cylinders close to each other and stores it in the storage trough, and then separates the material by the partition, thereby reducing the situation where the materials at different heights are not clearly separated due to the downward flow of the materials, and facilitating the subsequent grasping of whether the materials at the corresponding positions are qualified according to the test results. When the materials at the corresponding height are unqualified, it indicates that the materials at the corresponding height in the transport vehicle are unqualified, thereby improving the accuracy of the test and facilitating subsequent processing.

[0038] 3. The present invention uses a limiting component to tightly limit the position of the plate at the bottom of the adjusting plate, so as to avoid the situation that when the semi-cylinders are close to each other to extrude materials, the reverse force of the materials causes the lower ends of the plate and the semi-cylinder to be loosely closed, thereby avoiding leakage of materials and affecting the stability of sampling. In addition, through the cooperation of the clutch component, the height of the plate at the bottom of the adjusting plate is adjusted according to the transport vehicles with different scoop depths, so as to reduce the situation that when sampling on transport vehicles with shallow scoops, there is a large amount of excess of the plate and the semi-cylinder at the bottom of the adjusting plate, thereby further improving the stability of sampling.

[0039] 4. The present invention facilitates the discharge of materials in storage troughs at different heights through the discharge assembly, and by positioning the baffle plate on the inner wall of one end of the first tube body close to the storage trough when the materials in the storage trough are not discharged, it prevents the materials from entering the first tube body when the semi-cylinder is inserted into the materials.

[0040] 5. By making the pressing plate and the pressing block move with the baffle, it is avoided that the material is accumulated in the second tube body due to extrusion, causing blockage of the second tube body, and improving the stability of material discharge. Since the pressing plate is designed in a bent shape, when the baffle moves upward, the pressing plate is close to the bottom inner wall of the second tube body. When the baffle moves downward, the pressing plate moves obliquely downward with the baffle, thereby not affecting the baffle and the actual use of material discharge.

[0041] 6. By moving the baffle downward, the tension spring is stretched, thereby acting on the material in the storage trough to avoid the material in the storage trough from being discharged smoothly due to large extrusion interaction. The reciprocating movement of the electric push rod can extend or contract the tension spring multiple times, which is convenient for practical use. BRIEF DESCRIPTION OF THE DRAWINGS

A discharge component 48 for discharging the materials in the semi-cylinder 42 is provided on the front side of one of the semi-cylinders 42.

[0066] The partition assembly 49 comprises:

[0067] The material storage trough 491 is provided on one side where the semi-cylinders 42 are close to each other, so that the material can enter the semi-cylinders 42 when the semi-cylinders 42 are close to each other. The inner wall of the material storage trough 491 is provided with guide grooves 497 arranged at intervals, and the inner wall of the guide groove 497 is provided with a guide plate 492. The side wall of the guide plate 492 is fixed with a partition 493 extending into the material storage trough 491 to separate the space of the material storage trough 491.

[0068] See also Fig. 9 and Fig.10 The sampling mechanism 4 also includes a mounting seat 43 disposed at the bottom of the position adjustment mechanism, and the moving assembly 45 includes:

[0069] The second movable groove 454 is opened on the side of the mounting seat 43 close to the semi-cylinder 42. The inner wall of the second movable groove 454 is sleeved with an adjustment plate 451 extending to the outside of the plate body 41, and the adjustment plate 451, the semi-cylinder 42 and the plate body 41 are symmetrically arranged with respect to the center point of the mounting seat 43. The top and bottom of the adjustment plate 451 are respectively fitted with the top and bottom of the inner wall of the second movable groove 454. The inner side of the adjustment plate 451 is provided with a clutch assembly 46 for adjusting the connection or disconnection between the plate body 41 and the adjustment plate 451. The bottom of the adjustment plate 451 is provided with a limit assembly 44 for pressing against the semi-cylinder 42.

[0070] The mobile assembly 45 also includes:

[0071] The threaded rod 453 is rotatably disposed on the side wall of the mounting seat 43 and extends into the second moving groove 454. Both ends of the side wall of the threaded rod 453 are respectively threadedly connected with the symmetrically arranged adjustment plates 451. The threaded rod 453 adopts a bidirectional screw design to drive the adjustment plates 451 to move closer to or away from each other. A servo motor 452 is disposed on the top of the mounting seat 43 to drive the threaded rod 453 to rotate.

[0072] The slide groove 455 is formed on the inner wall of the second movable groove 454 . A slider is disposed inside the slide groove 455 . The slider is fixedly connected to a side of the adjustment plate 451 away from the plate body 41 to limit the movement of the adjustment plate 451 .

[0073] In the specific implementation, the servo motor 452 is started, and the threaded rod 453 is driven to rotate by the servo motor 452, thereby driving the adjustment plate 451 to move away from each other along the second moving groove 454 and the slide groove 455, so that the symmetrically arranged semi-cylinders 42 and the plate body 41 are moved away from each other, which is convenient for inserting the semi-cylinders 42 and the plate body 41 into the material. Then, the servo motor 452 is reversed, so that the semi-cylinders 42 are close to each other. In this process, the material between the semi-cylinders 42 enters the storage trough 491. As the semi-cylinders 42 are fitted together, the material is stored in the storage trough 491, so as to take the material in the transport vehicle. Sampling, by first separating the semi-cylinder 42 and the plate 41 and then inserting them into the material, and then bringing the semi-cylinders 42 closer to each other, so that the material enters the storage tank 491 for sampling, reducing the situation in which the material flows downward during the traditional sampling process, resulting in more upper materials in the sampled material, which affects the accuracy of subsequent detection, and the semi-cylinders 42 are closer to each other to facilitate the material to enter the storage tank 491, avoiding the situation in which the traditional material enters the sampling mechanism 4 only by its own fluidity, resulting in a small sampling amount or even no sampling, which is convenient for actual sampling and use, and thus convenient for subsequent detection, avoiding reducing the detection efficiency;

[0074] The output shaft of the servo motor 452 is fixed with a rotating shaft through a coupling, and the side wall of the rotating shaft and the side wall of one end of the threaded rod 453 located outside the mounting seat 43 are fixedly sleeved with gears, and the gears are connected through a chain transmission to drive the threaded rod 453 to rotate through the servo motor 452. The outer wall of the mounting seat 43 is fixed with a protective cover sleeved on the outside of the gear and the chain, and the rotating shaft is rotatably connected with the protective cover, which protects the gear and the chain while facilitating the stability of the rotation of the rotating shaft;

[0075] The second moving groove 454 and the sliding groove 455 limit the movement of the adjusting plate 451, thereby improving the stability of the movement of the adjusting plate 451, thereby improving the stability of the movement of the semi-column 42 and the plate body 41.

[0076] See also Figure 7 and Figure 8 , the partition assembly 49 further comprises:

[0077] The first movable groove 494 is formed on the inner wall of the guide groove 497 and extends into the semi-cylinder 42 and the plate body 41. The first movable groove 494 is connected to the guide grooves 497 arranged at intervals. A movable plate 498 is sleeved on the inner wall of the first movable groove 494. One side of the movable plate 498 is fixedly connected to the side of the guide plate 492 away from the partition 493 to connect the guide plates 492 arranged at intervals, so that the partitions 493 arranged at intervals move synchronously. A first electromagnet 495 is fixedly provided on the other side of the movable plate 498.

[0078] The second electromagnet 496 is fixedly disposed on the inner wall of the first moving groove 494 , and the second electromagnet 496 and the first electromagnet 495 are disposed facing each other.

[0079] In a specific implementation, when the semi-cylinders 42 are close to each other to clamp the material into the storage tank 491, the first electromagnet 495 and the second electromagnet 496 are started, and the side where the first electromagnet 495 and the second electromagnet 496 are close to each other is the same pole, so that the first electromagnet 495 is driven to move by the repulsive force generated, thereby driving the moving plate 498 to move along the first moving groove 494, so as to drive the guide plate 492 and the partition plate 493 to move along the guide groove 497, so as to divide the interior of the storage tank 491 into multiple parts in the height direction, so as to separate the material in the storage tank 491. Separated, so that the subsequent discharge assembly 48 can discharge materials at different heights, so as to facilitate the detection of materials at different heights. After the semi-cylinders 42 are close to each other to clamp the materials and store them in the storage tank 491, the materials are separated by the partition 493 to reduce the situation where the materials at different heights are not clearly separated due to the downward flow of the materials, so as to facilitate the subsequent grasp of whether the materials at the corresponding positions are qualified according to the test results. When the materials at the corresponding height are unqualified, it indicates that the materials at the corresponding height in the transport vehicle are unqualified, thereby improving the accuracy of the detection and facilitating subsequent processing;

[0080] When a sampling is completed, the side where the first electromagnet 495 and the second electromagnet 496 are close to each other is a different pole, so that the movable plate 498, the guide plate 492 and the partition plate 493 are reset by the generated suction force, so as to facilitate the next sampling. The magnetic pole direction of the electromagnet can be adjusted by the current direction, which is a prior art and will not be described in detail here.

[0081] The movable plate 498 and the first movable groove 494 facilitate connection of a plurality of guide plates 492 arranged at intervals, thereby facilitating synchronous movement of a plurality of partition plates 493 , which is convenient for practical use.

[0082] The height of the guide plate 492 is greater than the height of the partition plate 493, so that the inner wall of the guide groove 497 cooperates with the side wall stop of the guide plate 492, thereby limiting the separation of the partition plate 493 from the guide groove 497, and the inner wall of the guide groove 497 on one side close to the material storage trough 491 fits with the side wall of the partition plate 493, so as to limit the material from entering the guide groove 497;

[0083] An insert plate 47 is fixedly provided at the bottom of the semi-cylinder 42 and the plate 41, and the outer side of the insert plate 47 is inclined, and the inner side of the insert plate 47 is vertically aligned with the side of the semi-cylinder 42 away from the plate 41, so that the semi-cylinder 42 and the plate 41 can be easily inserted into the material through the insert plate 47;

[0084] The diameter of the semi-cylinder 42 is greater than the length of the plate 41, so that when the abutment plates 441 of the subsequent limiting components 44 approach each other, the semi-cylinder 42 blocks the position of the abutment plates 441, thereby limiting the semi-cylinder 42 and improving the stability of the semi-cylinders 42 approaching each other.

[0085] Example 2: Please refer to Fig.10 and Fig.11 The technical solution of this embodiment is different from that of the first embodiment in that the clutch assembly 46 includes:

[0086] The frame 461 is fixedly arranged on the inner side of the adjusting plate 451, and the inner side of the frame 461 is sleeved on the outer side of the plate 41. The inner side of the frame 461 is provided with a limiting groove 464, and the limiting groove 464 extends to the outer side of the frame 461. The inner wall of the limiting groove 464 is sleeved with a limiting ring 463, and the inner wall of the limiting ring 463 is fixedly sleeved with a limiting rod 462 extending to the inner side of the frame 461 and the outer side of the frame 461, so that the limiting ring 463 and the limiting rod 462 are moved along the limiting groove 464. The inner wall of the positioning groove 464 moves, and the limiting ring 463 cooperates with the stopper of the limiting groove 464 to limit the limiting rod 462 from being separated from the limiting groove 464. The limiting rod 462 is located on one end side wall of the limiting groove 464 and is located on one side of the limiting ring 463 close to the outside of the frame 461. A spring is provided to make the limiting rod 462 tend to move toward the inside of the frame 461. Slots matching the limiting rod 462 are provided on the front and back of the plate body 41, and are arranged at intervals.

[0087] In specific implementation, the end of the limit rod 462 located outside the frame 461 is pulled to disengage the limit rod 462 from the slot, and the connection position between the adjustment plate 451 and the plate body 41 can be adjusted. After the adjustment is completed, the limit rod 462 is released, and under the action of the spring, the limit rod 462 and the limit ring 463 are moved to the inside of the frame 461 and inserted into the slots on the front and back of the plate body 41, so as to adjust the height of the plate body 41 at the bottom of the adjustment plate 451, so as to facilitate adjustment according to transport vehicles with different vehicle pocket depths, and facilitate actual sampling use;

[0088] By providing limiting rods 462 and the like on the front and back of the frame 461 to limit the front and back of the plate 41 , the stability of the connection between the plate 41 and the frame 461 is improved.

[0089] See also Figure 2 and Fig.10 , the limiting assembly 44 includes:

[0090] The movable through slot 442 is opened on the bottom inner wall of the second movable groove 454. The inner wall of the movable through slot 442 is sleeved with a support plate 441, and the top of the support plate 441 is fixedly connected to the bottom of the adjustment plate 451. The side of the support plate 441 away from the adjustment plate 451 is in contact with the connection between the plate body 41 and the semi-cylinder 42.

[0091] In specific implementation, when the moving component 45 drives the semi-cylinder 42 to approach each other, the adjusting plate 451 drives the abutting plate 441 to move synchronously along the moving through groove 442, and because the diameter of the semi-cylinder 42 is greater than the length of the plate body 41, when the abutting plate 441 moves, it drives the semi-cylinder 42 to move, thereby tightly limiting the plate body 41 at the bottom of the adjusting plate 451, that is, the lower end of the plate body 41, to avoid the situation where the lower ends of the plate body 41 and the semi-cylinder 42 are not tightly closed due to the reverse force of the material when the semi-cylinder 42 approaches each other to extrude the material, to avoid the situation where material leakage occurs, so as to avoid affecting the stability of sampling. Through the cooperation of the clutch component 46, the height of the plate body 41 at the bottom of the adjusting plate 451 is adjusted according to the transport vehicles with different cart hood depths, to reduce the situation where there is a large amount of margin of the plate body 41 and the semi-cylinder 42 at the bottom of the adjusting plate 451 when sampling the transport vehicles with shallow cart hoods, thereby further improving the stability of sampling.

[0092] For example 3, please refer to Fig.12 , Fig.13 and Fig.14 The difference between this embodiment and the second embodiment is that the discharge assembly 48 includes:

[0093] The first tube body 482 is fixedly mounted on the front side of one of the semi-cylinders 42 and extends into the material storage trough 491. One end of the first tube body 482 located in the material storage trough 491 is designed in an arc shape to fit with the inner wall of the material storage trough 491. The bottom of the first tube body 482 is fixedly provided with a second tube body 486 extending to the outside of the semi-cylinder 42, and the second tube body 486 is connected to the first tube body 482. The second tube body 486 and the first tube body 482 are both designed to be inclined, and the inclination angle of the first tube body 482 is smaller than the inclination angle of the second tube body 486. The end of the first tube body 482 located outside the semi-cylinder 42 is designed to be sealed.

[0094] The discharge assembly 48 also includes:

[0095] The electric push rod 481 is fixed to the inner wall of one end of the first tube 482 outside the semi-cylinder 42. The telescopic shaft of the electric push rod 481 is fixed with a baffle 484, and the side wall of the baffle 484 is in contact with the inner wall of the first tube 482.

[0096] The pressing plate 485 is fixedly arranged on the side of the baffle 484 close to the electric push rod 481, and a pressing block 487 is fixedly arranged on the side of the pressing plate 485 away from the baffle 484. The pressing plate 485 is designed in a bent shape;

[0097] The tension spring 483 is fixedly arranged on the side of the baffle 484 away from the electric push rod 481 . The side of the tension spring 483 away from the baffle 484 is fixedly connected to the inner wall of the storage trough 491 . The tension spring 483 is inclined and located on the top of the partition 493 .

[0098] In specific implementation, after the semi-cylinder 42 takes the material out of the transport vehicle, the sampling mechanism 4 is transferred to the designated position through the position adjustment mechanism, and then the electric push rod 481 is started, and the telescopic shaft of the electric push rod 481 drives the baffle 484 to move downward, so that the baffle 484 moves to the bottom or the middle and lower section of the connection between the first tube body 482 and the second tube body 486, so that the material in the storage tank 491 is discharged along the inner wall of the first tube body 482, the connection between the first tube body 482 and the second tube body 486, thereby facilitating the discharge of the material in the storage tank 491 at different heights, and by making the baffle 484 located at the inner wall of one end of the first tube body 482 close to the storage tank 491, that is, the top of the connection between the first tube body 482 and the second tube body 486 when the material in the storage tank 491 is not discharged, it is prevented that the material enters the first tube body 482 when the semi-cylinder 42 is inserted into the material, thereby playing a blocking role;

[0099] When the baffle 484 moves downward, it drives the pressing plate 485 and the pressing block 487 to move downward. When the semi-cylinder 42 moves downward, the bottom of the second tube 486 is inserted into the material, and the material will enter the second tube 486. By moving the pressing block 487 downward with the baffle 484, it is prevented that the material is squeezed and accumulated in the second tube 486, causing blockage of the second tube 486, thereby improving the stability of material discharge. Since the pressing plate 485 is designed in a bent shape, when the baffle 484 moves upward, the pressing plate 485 is close to the bottom inner wall of the second tube 486. When the baffle 484 moves downward, the pressing plate 485 moves obliquely downward with the baffle 484, thereby not affecting the baffle 484 and the actual material discharge.

[0100] The baffle plate 484 moves downward and drives the tension spring 483 to stretch, thereby acting on the material in the storage tank 491, so as to avoid the material in the storage tank 491 from being discharged unsmoothly due to the large extrusion interaction. The electric push rod 481 moves back and forth, so that the tension spring 483 can be stretched or contracted multiple times, which is convenient for practical use.

[0101] By making the first tube body 482 and the second tube body 486 both inclined, it is convenient for actual material discharge and reduces the amount of material accumulated in the first tube body 482 and the second tube body 486 after the semi-cylinder 42 is inserted into the material.

[0102] The electronic components of the present invention, such as the servo motor 452, the first electromagnet 495 and the electric push rod 481, are all connected to an external power source and a controller through wires for practical control and use. This is prior art and will not be described in detail here.

[0103] The embodiment of the present invention further provides a method for using an automatic sampling and detection device for automobile transport materials, using an automatic sampling and detection device for automobile transport materials, the method comprising the following steps:

[0104] S1: driving a transport vehicle for transporting materials to the bottom of the gantry 1, and then adjusting the position of the sampling mechanism 4 through the position adjustment mechanism so that the sampling mechanism 4 samples the designated position;

[0105] S2: When the sampling mechanism 4 is sampling, the semi-cylinder 42 and the plate 41 are first moved away from each other by the moving component 45, and then the semi-cylinder 42 and the plate 41 are inserted into the material, and then the semi-cylinder 42 and the plate 41 are moved closer to each other by the moving component 45 to clamp the material in the material storage tank 491, thereby reducing the problem of inaccurate sampling at different heights caused by the traditional automatic flow of materials into the sampling mechanism 4;

[0106] S3: After the material is clamped in the storage tank 491, the material in the storage tank 491 is separated by the partition component 49 to collect materials at different heights, and to facilitate the subsequent discharge component 48 to discharge the materials at different heights. Then, the semi-cylinder 42 is moved upward, and the materials at different heights are discharged by the discharge component 48 to complete the sampling of materials at different heights;

[0107] The connection position between the adjustment plate 451 and the plate body 41 is adjusted by the clutch assembly 46, so as to adjust the height of the plate body 41 at the bottom of the adjustment plate 451, thereby facilitating sampling of vehicles with different vehicle pocket depths, and cooperating with the limit assembly 44 to facilitate limiting the lower ends of the plate body 41 and the semi-cylinder 42, so as to avoid the lower end of the main body from warping outward when the semi-cylinder 42 is driven closer to each other from the upper end of the plate body 41, thereby avoiding leakage of materials and affecting the material sampling.
