DETAILED DESCRIPTION

[0028] The technical scheme of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example:

[0030] See also Figure 1 - Figure 6As shown, an intelligent sampling robot arm includes a base 1, a rotating chassis 5 is arranged on the upper surface of the base 1, a mounting column 6 is arranged on the upper surface of the rotating chassis 5, an annular groove 22 is opened on the upper surface of the base 1, and a roller 21 is arranged on the lower surface of the rotating chassis 5, and four groups of rollers 21 are arranged, and the bottoms of the four groups of rollers 21 are all arranged inside the annular groove 22. The setting of the annular groove 22 provides a movable space for the roller 21, so that the roller 21 can stably move inside the annular groove 22, and the setting of the roller 21 can support the rotating chassis 5, so that the rotating chassis 5 is stably installed on the upper surface of the base 1, and does not affect the rotation of the rotating chassis 5;

[0031] A lifting seat 7 is arranged inside the mounting column 6, wherein a lifting slot is provided inside the right side of the mounting column 6 to provide lifting space for the lifting seat 7 so that the lifting seat 7 can move vertically smoothly. A rotation adjustment mechanism 2 is arranged inside the base 1, and the rotation adjustment mechanism 2 includes a servo motor 201, and the servo motor 201 is arranged inside the base 1. The power output end of the servo motor 201 is connected to a motor shaft 202 through a coupling transmission, and the left and right sides of the motor shaft 202 are connected to a rotating shaft 204 through a plug-in limit plate 203. A limit slot 4 matching the plug-in limit plate 203 is provided inside the rotating shaft 204. The setting of the limit slot 4 provides a plug-in limit plate 203 with a rotation adjustment mechanism 2. The limit plate 203 provides a plug-in space, so that the plug-in limit plate 203 can be stably plugged into the inside of the limit groove 4, and then the motor shaft 202 can be connected with the rotating shaft 204 through the plug-in limit plate 203. The circumferential surface of the rotating shaft 204 is provided with a rotating gear 209, and the left side of the rotating gear 209 is meshedly connected with a driven gear 210, and the left side of the driven gear 210 is meshedly connected with a hollow rotating rod 212 through an annular internal gear plate 213. The upper end of the hollow rotating rod 212 is plugged with a threaded rod 208, and the threaded rod 208 is rotatably installed inside the mounting column 6, and the lifting seat 7 is threadedly connected to the circumferential surface of the threaded rod 208;

[0032] It should be noted that the lower end of the threaded rod 208 is only inserted into the upper end of the hollow rotating rod 212, that is, when the rotating shaft 204 drives the hollow rotating rod 212 to rotate through the rotating gear 209, the driven gear 210 and the annular internal gear plate 213, the hollow rotating rod 212 will not drive the threaded rod 208 to rotate, and when the threaded rod 208 rotates alone, the threaded rod 208 will not drive the hollow rotating rod 212 to rotate.

[0033] The upper surface of the rotating shaft 204 is provided with a cross plug block 207, and the lower end of the threaded rod 208 is provided with a cross slot 20 that matches the cross plug block 207. The setting of the cross slot 20 provides a plug-in space for the cross plug block 207, so that the cross plug block 207 can be smoothly plugged into the lower end of the threaded rod 208, and then the rotating shaft 204 is connected to the threaded rod 208 through the cross plug block 207. The circumferential surface of the lower end of the rotating shaft 204 is provided with a lifting plate 205. Lifting cylinders 206 are provided at both left and right ends of the lower surface of the lowering plate 205, and the lifting cylinders 206 are provided at the inner bottom of the base 1. The driven gear 1 210 is rotatably mounted on the lifting plate 205 by rotating the support rod 3, which can limit the position of the driven gear 1 210 without affecting the rotation of the driven gear 1 210. The upper surface of the lifting plate 205 is provided with an annular clamping tooth plate 211, and the circumferential outer surface of the bottom of the hollow rotating rod 212 is provided with an annular outer tooth plate 214 matching the annular clamping tooth plate 211.

[0034] It should be noted that the annular engaging toothed plate 211 is arranged below the driven gear 1 210, and when the lifting cylinder 206 drives the lifting plate 205 to move upward, when the cross plug block 207 at the upper end of the rotating shaft 1 204 is plugged into the cross slot 20 opened inside the lower end of the threaded rod 1 208, the rotating gear 1 209 and the driven gear 1 210 will move to the top of the annular inner toothed plate 213, so that the driven gear 1 210 is no longer meshed with the annular inner toothed plate 213, and then the rotating gear 1 209 drives the driven gear 1 210 to rotate. When the moving gear 210 rotates, the driven gear 210 will no longer drive the hollow rotating rod 212 to rotate. At the same time, the annular clamping tooth plate 211 moves upward to the circumferential outer surface of the bottom of the hollow rotating rod 212, and the hollow rotating rod 212 is clamped and fixed by the annular outer tooth plate 214, so that the hollow rotating rod 212 and the rotating chassis 5 are limited and fixed. Then, when the motor shaft 202 drives the threaded rod 208 to rotate subsequently, the rotating chassis 5 will not be driven to rotate due to the friction, inertia and other forces generated by the threaded rod 208.

[0035] A folding storage mechanism 8 is arranged on the right side of the lifting seat 7. The folding storage mechanism 8 includes a servo motor 801, and the servo motor 801 is arranged inside the right side of the lifting seat 7. The power output end of the servo motor 801 is connected to the motor shaft 802 through a coupling transmission. The circumferential surface of the rear end of the motor shaft 802 is provided with a rotating gear 803. The right side of the rotating gear 803 is meshed and connected with a driven gear 804. The front end of the driven gear 804 is provided with a rotating shaft 805. The front and rear ends of the rotating shaft 805 are rotatably installed inside the lifting seat 7. The circumferential surface of the middle part of the rotating shaft 805 is provided with a rotating horizontal plate 806. The lower end of the right side wall of the seat 7 is provided with an abutment support plate 23, which abuts against the lower end of the left side wall of the rotating horizontal plate 806. The setting of the abutment support plate 23 can support the rotating horizontal plate 806 when the rotating horizontal plate 806 rotates to be parallel to the lifting seat 7, thereby improving the stability of the rotating horizontal plate 806 and limiting the rotation range of the rotating horizontal plate 806 to prevent the rotating horizontal plate 806 from continuing to rotate downward and affecting the use effect of the sampling rod 15. The front end of the right side of the lifting seat 7 is rotatably installed with a rotating shaft 3 807, and the rotating shaft 3 807 is located in front of the rotating shaft 2 805. The circumferential surface of the rotating shaft 3 807 is provided with a fixed gear 808;

[0036] The right outer wall of the rotating horizontal plate 806 is provided with a servo motor 3 9 through a motor box, the power output end of the servo motor 3 9 is connected to a threaded rod 2 10 through a coupling transmission, and the threaded rod 2 10 is rotatably installed inside the rotating horizontal plate 806, a moving block 11 is provided inside the rotating horizontal plate 806, the moving block 11 is threadedly connected to the circumferential surface of the threaded rod 2 10, the front end of the moving block 11 is rotatably installed with a mounting block 14 through a rotating shaft 4 12, a sampling rod 15 is provided in the middle of the mounting block 14, a driven gear 3 13 is provided on the circumferential surface of the rotating shaft 4 12, and the driven gear 3 13 matches the fixed gear 808;

[0037] It should be noted that a moving groove is provided inside the front end of the rotating horizontal plate 806, and the moving block 11 is arranged inside the moving groove, so that when the threaded rod 10 rotates, the moving block 11 can stably move horizontally left and right inside the moving groove. When the moving block 11 moves to the leftmost end of the moving groove, it drives the driven gear 3 13 to move to the left until it is engaged with the fixed gear 808. Then, when the rotating horizontal plate 806 is rotated, folded and stored, the driven gear 3 13 can engage and rotate on the fixed gear 808, thereby driving the sampling rod 15 to rotate. The upper end of the sampling rod 15 is connected to the grain transport pipe, and the grain transport pipe is a relatively long hose. When the mounting block 14 drives the sampling rod 15 to move horizontally left and right, or when the lifting seat 7 drives the sampling rod 15 to move vertically, it will not affect the grain transport pipe.

[0038] A slide groove 19 is provided at the bottom of the front end of the rotating cross plate 806, and a connecting plate 17 is arranged inside the slide groove 19. The arrangement of the slide groove 19 provides a movable space for the connecting plate 17, so that when the moving block 11 moves horizontally left and right inside the rotating cross plate 806, it can smoothly drive the connecting plate 17 to move horizontally left and right. A latch 16 is provided on the left side wall of the upper end of the connecting plate 17, and the left end of the latch 16 is inserted into the inside of the moving block 11 and the rotating shaft 4 12. A tensioning spring 18 is sleeved on the right circumferential surface of the latch 16. The left end of the tensioning spring 18 is connected to the right outer wall of the moving block 11, and the right end of the tensioning spring 18 is connected to the left side wall of the connecting plate 17. The latch 16 is inserted into the inside of the moving block 11 and the rotating shaft 4 12 by the elastic force of the tensioning spring 18, and the rotating shaft 4 12 can be limited to prevent the rotating shaft 4 12 from rotating during the sampling process of the sampling rod 15, which affects the sampling work of the sampling rod 15.

[0039] When the movable block 11 moves to the leftmost end of the rotating horizontal plate 806, the connecting plate 17 will first move to the leftmost end of the movable block 11, and then when the movable block 11 continues to move to the left, because the connecting plate 17 can no longer move to the left, the latch 16 will be pulled to stay in place. After the movable block 11 moves to the leftmost end of the rotating horizontal plate 806, the left end of the latch 16 will move out from the inside of the rotating shaft four 12, losing the fixing effect on the rotating shaft four 12. At this time, the mounting block 14 can be rotated on the movable block 11 through the rotating shaft four 12, so that when the rotating horizontal plate 806 is folded and stored, the mounting block 14 will also rotate synchronously to fold and store the sampling rod 15 so that the sampling rod 15 is in a parallel state with the rotating horizontal plate 806.

[0040] When the present invention is in use, after the vehicle transporting solid particles moves to the bottom of the intelligent sampling mechanical arm, the servo motor 3 9 is started, and the servo motor 3 9 drives the threaded rod 2 10 to rotate, so that the moving block 11 drives the rotating shaft 4 12, the mounting block 14 and the sampling rod 15 to move horizontally on the threaded rod 2 10, and the sampling rod 15 stops after moving to the top of the solid particle pile;

[0041] Then, the lifting cylinder 206 is started, and the lifting cylinder 206 drives the lifting plate 205 and the rotating shaft 204 to move upward, so that the cross plug block 207 on the upper surface of the rotating shaft 204 is plugged into the inside of the cross slot 20 at the bottom of the threaded rod 208, connecting the rotating shaft 204 and the threaded rod 208 together. At the same time, the rotating shaft 204 will also drive the rotating gear 209, the driven gear 210 and the annular clamping tooth plate 211 to move upward, so that the rotating gear 209 and the driven gear 210 move to the top of the annular inner tooth plate 213, so that the driven gear 210 loses the meshing effect with the annular inner tooth plate 213, and the annular clamping tooth plate 211 moves to the circumferential surface of the lower end of the hollow rotating rod 212 at this time. , the annular outer tooth plate 214 is clamped and fixed with the hollow rotating rod 212, and then the rotating chassis 5 is fixed, and then the servo motor 201 is started, and the servo motor 201 drives the motor shaft 202 to rotate, and the motor shaft 202 drives the threaded rod 208 to rotate through the cross plug block 207, so that the lifting seat 7 moves vertically on the threaded rod 208. When the lifting seat 7 moves downward, it can drive the rotating cross plate 806 and the sampling rod 15 to move downward, so that the lower end of the sampling rod 15 is inserted into the solid particle pile, so as to smoothly carry out the sampling work. After the sampling at this position is completed, the servo motor 201 is started again to rotate in the opposite direction, so that the sampling rod 15 moves to the top of the solid particle pile again;

[0042] Then the lifting cylinder 206 is started again, and the lifting cylinder 206 drives the lifting plate 205 and the rotating shaft 204 to move downward, and the rotating shaft 204 drives the cross plug block 207 to move downward and disengage from the threaded rod 208, so that the rotating shaft 204 loses the connection with the threaded rod 208, and at the same time, the rotating shaft 204 also drives the rotating gear 209, the driven gear 210 and the annular clamping tooth plate 211 to move downward, so that the rotating gear 209 and the driven gear 210 move downward to the same horizontal state as the annular inner tooth plate 213, and then the driven gear 210 is meshed with the left side of the annular inner tooth plate 213, and the annular clamping tooth plate 211 moves downward until it is no longer meshed and clamped with the annular outer tooth plate 214, so that the hollow rotating rod 212 loses the clamping The fixing effect can be used for rotation, and then the servo motor 201 is started. The servo motor 201 drives the motor shaft 202 to rotate, and the motor shaft 202 drives the rotating shaft 204 and the rotating gear 209 to rotate. The rotating gear 209 drives the hollow rotating rod 212 to rotate through the driven gear 210 and the annular inner gear plate 213, thereby driving the rotating chassis 5 to rotate. The rotating chassis 5 drives the mounting column 6, the rotating cross plate 806 and the sampling rod 15 to rotate, and then the position of the sampling rod 15 is adjusted. The servo motor 3 9 can also be started to make the moving block 11 drive the mounting block 14 and the sampling rod 15 to move on the threaded rod 2 10, and the sampling rod 15 is adjusted again, so that the sampling rod 15 can be conveniently used for sampling at different positions;

[0043] After the sampling is completed, the servo motor 3 9 is started, so that the moving block 11 drives the mounting block 14 and the sampling rod 15 to move to the leftmost end of the rotating horizontal plate 806. When the mounting block 14 is close to the leftmost end of the rotating horizontal plate 806, the connecting plate 17 cannot continue to move to the left because it has moved to the leftmost end of the slide slot 19. Then, when the moving block 11 continues to move to the left, the connecting plate 17 can no longer move to the left, thereby pulling the latch 16 to stay in place. Then, after the moving block 11 moves to the left to the leftmost end of the rotating horizontal plate 806, the left end of the latch 16 will move out from the inside of the rotating shaft 4 12, losing the fixing effect on the rotating shaft 4 12, and when the moving block 11 moves to the leftmost end, the driven gear 3 13 will mesh with the fixed gear 808.

[0044] Then, the servo motor 801 is started, and the servo motor 801 drives the motor shaft 802 and the rotating gear 803 to rotate, and the rotating gear 803 drives the driven gear 804 and the rotating shaft 805 to rotate, so that the rotating horizontal plate 806 rotates 90 degrees counterclockwise, so that the rotating horizontal plate 806 is parallel to the mounting column 6. At the same time, when the rotating horizontal plate 806 rotates, it drives the driven gear 3 13 to move on the fixed gear 808, and then drives the driven gear 3 13 to rotate, so that the driven gear 3 13 drives the rotating shaft Four 12, the mounting block 14 and the sampling rod 15 rotate, and then when the rotating cross plate 806 and the mounting column 6 are in a parallel state, the sampling rod 15 is also in a parallel state with the rotating cross plate 806, and then the rotating shaft 204 is connected to the threaded rod 208 through the cross plug block 207, and the servo motor 201 is started to rotate the threaded rod 208, and then the lifting seat 7 drives the rotating cross plate 806 to move vertically downward to the bottom, thereby reducing the overall space occupied by the intelligent sampling robot arm and facilitating subsequent placement and other work.
