Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Please refer to fig. 1-4, the present embodiment provides a sampling device of a robot for inspecting grain bins, which includes a hopper 1, a connecting shaft 3, a swinging shaft 6, a transmission shaft 8, a driving device 14 and a bottom plate 15 fixed on a chassis of the robot, wherein a fixing base 2 is fixed on one side of the hopper 1, one end of the connecting shaft 3 is fixedly connected with the fixing base 2, the other end of the connecting shaft 3 is fixedly connected with the swinging shaft 6 through a first cross connecting block 4, the swinging shaft 6 is fixedly connected with the transmission shaft 8 through a second cross connecting block 7, the output end of the driving device 14 is connected with the transmission shaft 8, and a driving output device is fixed on the bottom plate 15. During operation, the driving device 14 drives the transmission shaft 8 to rotate, the transmission shaft 8 drives the oscillating shaft 6 and the hopper 1 to do circular motion by taking the transmission shaft 8 as an axis, and the hopper 1 performs sampling by doing circular motion.

Wherein, because transmission shaft 8 is longer, be equipped with bearing frame subassembly 9 on bottom plate 15, the one end of transmission shaft 8 passes bearing frame subassembly 9 and is connected with second cross connecting block 7.

Wherein, be fixed with limit switch support 16 on the bottom plate 15, limit switch support 16 is located between drive arrangement 14 and bearing frame subassembly 9, is fixed with rotation stop limit switch 12 and reset stop limit switch 10 on the limit switch support 16, and the transmission shaft both sides are fixed with rotation respectively and stop spacing piece 13 and reset and stop spacing piece 11, and rotation stop spacing piece 13 cooperatees with rotation stop limit switch 12, and reset stops spacing piece 11 and resets and stops limiting switch and cooperatees.

Wherein, one side that fixing base 2 kept away from hopper 1 is equipped with and supplies connecting axle 3 male inside groove and spring plunger 5, and in spring plunger 5's tip inserted inside groove, the end portion of connecting axle 3 was equipped with the plunger hole with 5 looks adaptations of spring plunger, and this structure is for inserting the mode soon, simple structure, and it is convenient to change.

The working process is as follows:

the hopper 1 is an empty hopper at the sampling starting position, slowly enters grain flour along with the rotation of the empty hopper, and slowly comes out of the grain pile after passing through the middle position; when the rotation stop limiting piece 13 reaches the position of the rotation stop limiting switch 12, the rotation is stopped, and the hopper 1 is positioned at the sampling end position; the robot then reaches the designated position and takes out the sample in the hopper 1.

After sampling, the hopper 1 needs to be reset. That is, the hopper 1 is driven by the driving device 14 to continue circular motion, and when the reset stop limit piece 11 reaches the position of the reset stop limit switch 10, the rotation is stopped, and at this time, the hopper 1 is located at the sampling start position.
