Description

Technical Field

[0001] This utility model relates to grain quality testing technology, specifically a column-type grain truck grain sampling robot. Background Technology

[0002] When purchasing grain from outside sources, in order to ensure the quality of the purchased grain, the grain in the grain truck must be sampled before it is put into storage. The sampling is to test the impurity content and moisture content of the grain, thereby determining the quality of this batch of grain. This is a mandatory test that the grain purchasing station must perform before the grain is put into storage.

[0003] A search revealed that CN208420449U, a multi-point grain pile sampler, has the following problems: When only one mechanism (the moving gantry mechanism or the top trolley mechanism) is moving, linear sampling is possible, not sampling within a fan-shaped area. For example, after the vehicle is in position and samples one point, the entire gantry needs to be moved to the next point, resulting in a long sampling time. The overall structure is also large and inefficient. CN220207154U, a sampling robot and grain depot sampling system, requires the construction of a sampling overhead truss in the sampling area, resulting in a large footprint, slow robot movement during sampling, reduced sampling efficiency, and high manufacturing cost for a five-axis robot. Therefore, we propose a column-mounted grain cart sampling robot to solve the aforementioned problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a column-type grain sampling robot for grain trucks to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solution: it includes a support column, which is fixedly connected to the ground;

[0006] A first rotating assembly, the first rotating assembly including a support beam disposed on a support column;

[0007] The second rotating assembly includes a support plate disposed on the support beam;

[0008] The third rotating assembly includes a support base fixed on a support plate, an electric cylinder mounted on the support base, and two sampling arms arranged in parallel inside the support base. One end of the upper sampling arm is rotatably connected to the output end of the electric cylinder. A first rotating shaft, a second rotating shaft, and a third rotating shaft are rotatably connected from top to bottom inside the support base. The upper sampling arm is fixed outside the first rotating shaft, and the lower sampling arm is fixed outside the third rotating shaft. A swing rod is provided on the front and rear sides of the two sampling arms, and the two ends of the swing rod are rotatably mounted on the adjacent sampling arm. A support is rotatably connected to the top of the sampling arm, and the same sampling rod is provided in both supports.

[0009] The shielding assembly includes a first gear fixedly mounted on the front side of a first rotating shaft and a second rotating shaft, the two first gears meshing with each other, rotating arms fixedly connected to the front and rear ends of the second rotating shaft, and a same shielding canopy fixedly connected between the ends of the two rotating arms.

[0010] Preferably, the first rotating assembly includes a first motor fixed to the side of the support column, and the first motor, its output end, and the bottom of the support beam are all fixedly connected to a second gear. The support beam is rotatably connected to the top of the support column, and the two second gears mesh with each other.

[0011] Preferably, the second rotating assembly includes a second motor fixedly disposed within one end of the supporting beam, and a third gear is fixedly disposed at the output end of the second motor and at the bottom of the supporting plate. The two third gears mesh with each other, and the supporting plate is rotatably connected to the top of one end of the supporting beam.

[0012] Preferably, a baffle plate is fixedly connected to the front side of the support base, and the first gear is located between the baffle plate and the front side of the support base.

[0013] Preferably, a maintenance ladder is fixed to the front side of the supporting column.

[0014] Preferably, a counterweight is fixed at one bottom end of the supporting beam.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] By cooperating with the three rotating components, the working method of supporting the crossbeam rotation is more efficient. Secondly, the single column support reduces the footprint. Finally, the three-axis mechanical structure reduces the mechanical structure and lowers the manufacturing cost compared to the existing five-axis sampling robot.

[0017] By using a structure with two parallel sampling arms, a swing rod, and a support, the sampling rod moves downward in the same direction after being pushed by the electric cylinder. The lever principle enables the electric cylinder to move a short distance to drive the sampling rod to move a long distance. Finally, the protective canopy provides rain protection to the exposed electric cylinder after the sampling rod moves upward and resets, thus improving its service life. Attached Figure Description

[0028] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Please see Figures 1-8 As shown, a column-type grain sampling robot for grain carts includes a supporting column 1, which is fixed to the ground; a first rotating assembly, which includes a supporting beam 5 mounted on the supporting column 1; a second rotating assembly, which includes a supporting plate 6 mounted on the supporting beam 5; and a third rotating assembly, which includes a supporting base 7 fixed to the supporting plate 6. An electric cylinder 8 is mounted on the supporting base 7, and two sampling arms 9 are arranged in parallel within the supporting base 7, wherein the upper sampling arm... One end of 9 is rotatably connected to the output end of the electric cylinder 8. The first rotating shaft 10, the second rotating shaft 11 and the third rotating shaft 12 are rotatably connected from top to bottom in the support base 7. The upper sampling arm 9 is fixed outside the first rotating shaft 10 and the lower sampling arm 9 is fixed outside the third rotating shaft 12. The front and rear sides of the two sampling arms 9 are respectively provided with swing rods 13. The two ends of the swing rods 13 are respectively rotated on the adjacent sampling arms 9. The top of the sampling arm 9 is rotatably connected to the support 14. The same sampling rod 15 is provided in the two supports 14.

[0030] It should be noted that the supporting beam 5 can rotate around the supporting column 1 via the first rotating assembly, and the supporting plate 6 can rotate around the supporting beam 5 via the second rotating assembly. Since the second and third rotating assemblies, which have a larger mass, are located at a relatively far end of the supporting beam 5, a counterweight 2 is provided below its other end to ensure the stability of the supporting beam 5. The first rotating shaft 10 and the third rotating shaft 12 respectively provide the rotation centers of the two sampling arms 9. The swing arm 13 ensures that the two sampling arms 9 rotate synchronously, acting on the end support 14, so that the two supports 14 can synchronously drive the sampling rod 15 downwards. Because the two sampling arms 9, the swing arm 13, and the two... The design of the support 14 allows the sampling rod 15 to move in an arc during descent when the end of the electric cylinder 8 extends, and the end of the sampling rod 15 will always be in the same direction. Therefore, in order to ensure that the sampling rod 15 is always vertically downward, the end support 14 should be in a horizontal state so that the sampling rod 15 fixed inside can always be in a vertical state. Compared with the traditional lifting structure, this parallel linkage structure can save vertical space. Moreover, due to the presence of the first rotating shaft 10 and the third rotating shaft 12, the sampling arm 9 rotates around them to form a lever structure, so that the end of the electric cylinder 8 only needs to be pushed out a short distance to move the sampling rod 15 a large distance, so that the sampling rod 15 can be in place more quickly.

[0031] The shielding assembly includes a first gear 16 fixedly mounted on the front side of the first rotating shaft 10 and the second rotating shaft 11 respectively. The two first gears 16 mesh with each other. The front and rear ends of the second rotating shaft 11 are respectively fixedly connected to rotating arms 17. The ends of the two rotating arms 17 are fixedly connected to the same shielding canopy 18.

[0032] It should be noted that the first shaft 10, driven by the first gear 16, rotates in the opposite direction through the first shaft 10, which rotates with the electric cylinder 8 to drive the sampling arm 9. The second shaft 11 rotates in the opposite direction through the rotating arm 17. This allows the shield 18 to rotate in the opposite direction when the sampling rod 15 is lowering. At the same time, the shield 18 does not interfere with the movement of the end of the sampling arm 9. After the sampling rod 15 moves up and resets, the shield 18 can rotate in the opposite direction to the electric cylinder 8 to provide rain protection in rainy weather, preventing the exposed electric cylinder 8 from being exposed to sun and rain for a long time and accelerating aging and rusting.

[0033] In this embodiment, the first rotating component includes a first motor 19 fixedly mounted on the side of the support column 1. The first motor 19, its output end, and the bottom of the support beam 5 are all fixedly connected to second gears 20. The support beam 5 is rotatably connected to the top of the support column 1, and the two second gears 20 mesh with each other.

[0034] It should be noted that by meshing the two second gears 20, the rotation of the support beam 5 on the support column 1 can be achieved by driving the first motor 19, which facilitates the control of the sampling position of the sampling rod 15.

[0035] In this embodiment, the second rotating component includes a second motor 21 fixedly installed in one end of the support beam 5. The output end of the second motor 21 and the bottom of the support plate 6 are both fixedly provided with a third gear 22. The two third gears 22 mesh with each other, and the support plate 6 is rotatably connected to the top of one end of the support beam 5.

[0036] It should be noted that the meshing of the two third gears 22 enables the second motor 21 to drive the support plate 6 to rotate on the support beam 5, which facilitates further control of the sampling position of the sampling rod 15 in the second direction.

[0037] In this embodiment, a shielding plate 4 is fixedly connected to the front side of the support base 7, and the first gear 16 is located between the shielding plate 4 and the front side of the support base 7. The shielding plate 4 is used to hide and protect the first gear 16.

[0038] In this embodiment, a maintenance ladder 3 is fixedly provided on the front side of the support column 1. The maintenance ladder 3 makes it easy for maintenance personnel to climb onto the support column 1 for maintenance operations.

[0039] When sampling is required, the robot is connected to an external power source. The controller controls the operation of the first motor 19, the second motor 21, and the electric cylinder 8. The first motor 19 and the second motor 21 drive the second gear 20 and the third gear 22 respectively to mesh with each other, driving the support beam 5 and the support plate 6 to rotate, which in turn drives the sampling rod 15 to rotate to the appropriate position. Then, the end of the electric cylinder 8 moves upward, pushing the sampling arm 9 connected to it to rotate. The counter-thrust causes the electric cylinder 8 itself to rotate as well. The sampling arm 9 drives the other sampling arm 9 synchronously via the swing arm 13. The cylinder rotates, causing the support 14 at its end to lower the sampling rod 15 along an arc. During this process, the sampling rod 15 remains vertically downward. After the sampling is completed, the end of the electric cylinder 8 retracts, causing the sampling arm 9 to rotate in opposite directions around the first rotating shaft 10 and the third rotating shaft 12, which in turn causes the sampling rod 15 to move upward. At the same time, the rotating first rotating shaft 10 will drive the first gear 16 outside it to rotate. Through the meshing of the first gear 16, the second rotating shaft 11 and the rotating arm 17 will rotate in opposite directions, so that the shield awning 18 and the sampling arm 9 rotate in opposite directions to be directly above the electric cylinder 8.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
