Crawler-type bulk cargo yard intelligent sampling device

Abstract

This invention relates to the field of sampling technology, specifically to a tracked intelligent sampling device for bulk cargo in a storage yard. The device includes: a platform, a sampling rod inserted inside the platform, a storage hole inserted into the surface of the sampling rod, an inclined groove on the surface of the storage hole, a first extension plate and a second extension plate fixed to the surface of the storage hole, a horizontal plate inserted inside the storage hole, a force-bearing plate fixed to one end of the horizontal plate, and a limit strip fixed to the other end; and a horizontal bar and a top-holding rod inside the sampling rod. The advantages are: the invention proposes moving the top-holding rod and horizontal bar by starting the device. Because the top-holding rod is located inside the sampling rod and does not bend, it inserts into the circular hole and holds both sides of the circular hole, causing the storage hole to move on the surface of the sampling rod, ensuring a consistent position of the storage hole. When the sample enters the storage hole, the sampling height is consistent each time, unaffected by the bending of the sampling rod.

Description

Technical Field

[0001] This invention relates to the field of sampling technology, specifically to a tracked intelligent sampling device for bulk cargo in a storage yard. Background Technology

[0002] Bulk cargo, as a core raw material for bulk trade and industrial production, encompasses multiple categories such as minerals, grains, and building materials. Stockpiles in storage yards are characterized by significant lateral thickness and distinct vertical stratification. Horizontal stratification sampling is a crucial step in ensuring the accuracy of quality verification, trade settlement, customs supervision, and quality traceability. The impartiality and stratification representativeness of the sampling results directly determine the risk of trade disputes and the credibility of supervision. A review of existing publicly available technologies reveals five inherent defects in current bulk cargo sampling equipment: First, it primarily employs vertical downward sampling and a semi-automated, manually assisted control mode. However, when the sampling rod is inserted into the material, the material's compression causes the sampling rod to bend, which changes the sampling position and affects the accuracy of the sampling. Summary of the Invention

[0003] The purpose of this invention is to provide a tracked intelligent sampling device for bulk cargo in a storage yard, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a tracked intelligent sampling device for bulk cargo in a storage yard, comprising: The platform has a sampling rod inserted inside, and a storage hole is inserted into the surface of the sampling rod. An inclined groove is formed on the surface of the storage hole. A first extension plate and a second extension plate are fixed to the surface of the storage hole. A horizontal plate is inserted inside the storage hole. A force plate is fixed to one end of the horizontal plate, and a limit strip is fixed to the other end. A crossbar and a top holding rod are set inside the sampling rod. A round hole is formed on the surface of the storage hole, and the crossbar and the top holding rod are inserted into the round hole.

[0005] Preferably, the bottom of the platform is provided with a piston rod and a limiting rod. The bottom of the piston rod is provided with a cylinder, which can drive the piston rod to move up and down. The bottom of the limiting rod is provided with a limiting tube, and the limiting rod is inserted into the inside of the limiting tube, allowing the limiting rod to move up and down within the limiting tube.

[0006] Preferably, a connecting plate is fixed to the bottom of the cylinder and the limiting tube, and a fixing plate is fixed to the bottom of the connecting plate. The bottom of the fixing plate is connected to a rotating device, which drives the fixing plate to rotate. The sampling rod is inserted into the inside of the platform and can move laterally inside the platform.

[0007] Preferably, the sampling rod has slots on both sides of its surface, and the slots have teeth. A motor is fixed to the surface of the platform, and a gear is provided at the end of the motor. The gear is located inside the platform, and the teeth on the surface of the gear mesh with the teeth on the slotted surface. The rotation of the gear drives the sampling rod to move laterally.

[0008] Preferably, the sampling rod has an insertion hole inside, and the storage hole is inserted into the insertion hole. The storage hole can move up and down in the insertion hole. The sampling rod has an inner groove inside, and an extension ring is fixed at the bottom of the storage hole. The diameter of the extension ring is larger than the diameter of the storage hole. The extension ring is located in the inner groove and moves up and down with the storage hole.

[0009] Preferably, a partition is fixed inside the storage hole, and a circular hole is opened on the surface of the storage hole. The partition is located at the top of the circular hole. A crossbar and a top holding rod are inserted into the inner groove. The crossbar and the top holding rod are fixed together. The ends of the crossbar and the top holding rod are connected to a driving device. The driving device drives the crossbar and the top holding rod to move laterally in the inner groove.

[0010] Preferably, the crossbar and the top holding rod are inserted into the inside of the circular hole, and the crossbar and the top holding rod can move in the circular hole. After the top holding rod moves, it can hold the edge of the circular hole. A first extension plate and a second extension plate are fixed on both sides of the storage hole.

[0011] Preferably, a horizontal plate is inserted into the first extension plate, the second extension plate, and the storage hole. A force plate and a limiting strip are fixed to the end of the horizontal plate. The force plate, the limiting strip, and the horizontal plate can move laterally inside the storage hole, the first extension plate, and the second extension plate.

[0012] Preferably, the surface of the horizontal plate is provided with a through hole. The through hole moves with the horizontal plate. When the limiting strip is pressed against the surface of the second extension plate, the through hole is located inside the first extension plate. When the force plate is pressed against the surface of the storage hole, the through hole is located inside the second extension plate.

[0013] Preferably, when the through hole is located inside the storage hole, it allows the inside of the storage hole to communicate with the outside.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The present invention proposes that when the sampling rod is inserted into the material, by pulling back the sampling rod, the material is held against the other side of the force plate, causing the force plate to move the horizontal plate, so that the through hole moves into the storage hole. The material can enter the storage hole through the through hole, and the partition plate supports the bottom of the storage hole, so the material is sampled inside the storage hole. When the sampling rod is pulled out, the limiting strip holds the end of the second extension plate, so that the through hole enters the first extension plate, and the through hole is blocked again, so the sample is stored inside the storage hole. When the sampling rod bends when inserted into the material, the device is started to drive the top holding rod and the horizontal bar to move. Since the top holding rod is located inside the sampling rod and does not bend, the top holding rod is inserted into the round hole and holds both sides of the round hole, so that the storage hole moves on the surface of the sampling rod, so that the position of the storage hole remains consistent. When the sample enters the storage hole, the sampling height is consistent each time and is not affected by the bending of the sampling rod. Attached Figure Description

There is a through hole 21. The through hole 21 moves with the horizontal plate 13. When the limiting strip 17 abuts against the surface of the second extension plate 16, the through hole 21 is located inside the first extension plate 14. When the force plate 12 abuts against the surface of the storage hole 22, the through hole 21 is located inside the second extension plate 16. When the through hole 21 is located inside the storage hole 22, the inside of the storage hole 22 can communicate with the outside. The horizontal plate 13 covers the storage hole 22. When the sampling rod 3 is inserted into the inside of the material, by pulling back the sampling rod 3, the material is held against the other side of the force plate 12, so that the force plate 12 drives the horizontal plate 13 to move.

[0024] Example 2: Based on Example 1, a piston rod 4 and a limiting rod 9 are provided at the bottom of platform 1. A cylinder 5 is provided at the bottom of the piston rod 4, which can drive the piston rod 4 to move up and down. A limiting tube 8 is provided at the bottom of the limiting rod 9, and the limiting rod 9 is inserted into the limiting tube 8, allowing it to move up and down within the limiting tube 8. A connecting plate 6 is fixed to the bottom of the cylinder 5 and the limiting tube 8, and a fixing plate 7 is fixed to the bottom of the connecting plate 6. A rotating device is connected to the bottom of the fixing plate 7, which drives the fixing plate 7 to rotate. The sampling rod 3 is inserted into platform 1. Inside the platform 1, the sampling rod 3 can move laterally. An insertion hole 15 is provided inside the sampling rod 3, and a storage hole 22 is inserted into the insertion hole 15. The storage hole 22 can move up and down within the insertion hole 15. An inner groove 18 is provided inside the sampling rod 3. An extension ring 25 is fixed to the bottom of the storage hole 22. The diameter of the extension ring 25 is larger than the diameter of the storage hole 22. The extension ring 25 is located in the inner groove 18 and moves up and down with the storage hole 22. A partition 23 is fixed inside the storage hole 22, and a circular hole 24 is provided on the surface of the storage hole 22. Plate 23 is located at the top of the circular hole 24. A crossbar 19 and a top holding rod 20 are inserted into the inner groove 18 and fixed together. The ends of the crossbar 19 and the top holding rod 20 are connected to a driving device. The driving device drives the crossbar 19 and the top holding rod 20 to move laterally in the inner groove 18. The crossbar 19 and the top holding rod 20 are inserted into the inside of the circular hole 24 and can move in the circular hole 24. After moving, the top holding rod 20 can hold against the edge of the circular hole 24. A first extension plate 14 and a second extension plate 16 are fixed on both sides of the storage hole 22. A horizontal plate 13 is inserted into the first extension plate 14, the second extension plate 16, and the storage hole 22. A force plate 12 and a limiting strip 17 are fixed to the end of the horizontal plate 13. The force plate 12, the limiting strip 17, and the horizontal plate 13 can move laterally inside the storage hole 22, the first extension plate 14, and the second extension plate 16. The force plate 12 drives the horizontal plate 13 to move, so that the through hole 21 moves into the storage hole 22. The material can enter the storage hole 22 through the through hole 21, and the partition plate 23 supports the bottom of the storage hole 22. The material is sampled inside the storage hole 22.

[0025] The sampling rod 3 has slots 10 on both sides of its surface, and the surface of the slots 10 has teeth. The surface of the platform 1 is fixed with a motor 2, and the end of the motor 2 is equipped with a gear. The gear is located inside the platform 1, and the teeth on the surface of the gear mesh with the teeth on the surface of the slots 10. The rotation of the gear drives the sampling rod 3 to move laterally. The starting device drives the top holding rod 20 and the crossbar 19 to move. Since the top holding rod 20 is located inside the sampling rod 3 and does not bend, the top holding rod 20 is inserted into the round hole 24 and holds both sides of the round hole 24, so that the storage hole 22 moves on the surface of the sampling rod 3, so that the position of the storage hole 22 remains consistent.

[0026] The fixing plate 7 is fixed to the surface of the mobile device. The mobile device drives the fixing plate 7 to move. The motor 2 drives the gear at the end, and the teeth on the gear surface mesh with the surface of the sampling rod 3, driving the sampling rod 3 to move inside the platform 1, so that the sampling rod 3 is inserted into the material. During the insertion process, the inclined groove 11 is supported by the material, so that the storage hole 22 is located inside the sampling rod 3. The force plate 12 is supported by the material, which drives the horizontal plate 13 to move laterally, so that the force plate 12 is supported on the surface of the storage hole 22. The through hole 21 is located inside the second extension plate 16. The horizontal plate 13 covers the storage hole 22. After the sampling rod 3 is inserted into the material, by pulling back the sampling rod 3, the material is supported on the other side of the force plate 12, so that the force plate 12 drives the horizontal plate 13 to move, so that the through hole 21 moves into the storage hole 22. Material can enter the storage hole 22 through the through hole 21, and the partition plate 23 supports the bottom of the storage hole 22. The material is sampled inside the storage hole 22. When the sampling rod 3 is pulled out, the limiting strip 17 presses against the end of the second extension plate 16, so that the through hole 21 enters the first extension plate 14. The through hole 21 is blocked again, and the sample is stored inside the storage hole 22. When the sampling rod 3 is inserted into the material and bends, the top holding rod 20 and the cross bar 19 are moved by starting the device. Since the top holding rod 20 is located inside the sampling rod 3 and does not bend, the top holding rod 20 is inserted into the round hole 24 and presses against both sides of the round hole 24, so that the storage hole 22 moves on the surface of the sampling rod 3, so that the position of the storage hole 22 remains consistent. When the sample enters the storage hole 22, the sampling height is consistent each time and is not affected by the bending of the sampling rod 3.

[0027] The device consists of a tracked off-road chassis, a sampling mechanism, a lifting and leveling support module, an intelligent control module, and an image recognition module. It enables closed-loop operation of the entire sampling process without human intervention. It can construct a three-dimensional model of the material pile through visual scanning, automatically and randomly generate horizontal sampling points, drilling depths, and high and low levels, covering the entire area of ​​the material pile for lateral layered sampling, ensuring fair and accurate sampling.
