Thereafter, the second gripper 48 at the hollow turntable 44 releases the sampling tube a5, and the drill 42 moves down the sampling tube a5 and the sampling tube b6, and the second gripper 48 at the hollow turntable 44 grips the sampling tube b 6. Thereafter, the drill 42 rotates reversely to release the sampling tube b6, and the drill 42 and the gripping mechanism 43 return to the initial state to wait for the sampling tube 3. The process of connecting the rod is completed by the circulation.
Grain pumping process: when the sampling tube is switched to the sampling point, the grain extractor 1 starts to work. The grain pumping pipe 12 is always connected with a connecting port at the upper end of the grain pumping mechanism screwed by the drill 42. The grain passes through the sampling tube to the drill 42, then to the grain pumping tube 12, and finally to the grain pumping device 1, completing the sampling.
The rod unloading process: the drill 42 lifts the plurality of sampling tubes, which have been successfully connected, up to the initial position, where the sampling tubes a5 are connected to the drill 42 at the upper end and connected to the sampling tubes b6 at the lower end. Thereafter, the second clamp 48 at the hollow turntable 44 clamps the sampling tube b6 and rotates, and at the same time, the drill 42 and the gripper 43 clamp the sampling tube a5 and move up, separating the sampling tube b6 from the sampling tube a 5. Then, the gripping mechanism 43 fixes the sampling tube a5, and the drill 42 is turned upside down and ascended to separate the sampling tube a5 from the drill 42, by which both ends of the sampling tube a5 are successfully separated.
The electric push rod 18 operates so that the first clamp 17 moves into the feeding assembly 4 to clamp the sampling tube a5, the gripping mechanism 43 in the feeding assembly 4 is released, and the first clamp 17 is turned over and pushed back into the rod magazine assembly 3 by the electric push rod 18.
After the sampling tube a5 is removed, the drill 42 moves downwards, is successfully connected with the sampling tube b6 and then is lifted to the initial state, the steps are repeated, and the rod unloading process is finished.
As shown in fig. 4; the drill bit 42 is fixed on the sliding seat 46 through the mounting seat 61, the end of the mounting seat 61 is fixed with the driving motor 62, the rotating shaft of the driving motor 62 is connected with the drill bit 42 through the gear set 65, the upper part of the mounting seat 61 is provided with the bearing 63, the upper part of the drill bit 42 penetrates through the mounting seat 61 to be connected with the inner ring of the bearing 63, the upper end face of the outer ring of the bearing 63 is connected with the upper end cover 64, the upper end cover 64 is fixed on the mounting seat 61 through screws, and the pipeline connector 51 is. The bearing inner race is connected to the drill bit upper end, and bearing outer race up end installs the upper end cover, and the upper end cover passes through the fix with screw on the mount pad, and the upper end cover upper portion is fixed with pipe connection, and when driving motor rotated, drove the drill bit and turned round the rotation, the pipe connection who takes out grain union coupling can keep quiescent condition, avoided the drill bit to damage and take out grain pipe in the feeding process.
