The working principle of the invention is as follows: under normal conditions, the case at the sending end is used for introducing compressed air into the pipeline to provide pressure to send out the warhead, the case at the receiving end is used for pumping air in the pipeline away, so that negative pressure is generated at one side of the receiving end, meanwhile, the air compensating valves of the secondary air compensating pipes, the air compensating directions of which are consistent with the conveying direction of the warhead, on the sample conveying main pipe are all opened, and the compressed air is further conveyed into the pipe to provide pressure, so that after the warhead enters the sample conveying main pipe from the buffer pipeline, the warhead is pushed by new power every time when moving for a certain distance until the warhead is conveyed to the case at the receiving end, and sample conveying is completed; when the warhead is clamped in the sample feeding main pipe, the secondary air supply pipes with different air supply directions alternately supply air to form pulse air flow to alternately impact the warhead to loosen the warhead, so that the pneumatic sample feeding machine is restored to normal work.
The beneficial effects are that: according to the pneumatic sample feeder, the sample feeding main pipe is provided with the plurality of groups of secondary air supplementing pipes which are obliquely connected with the sample feeding main pipe, so that the warhead can be pushed by new power every time the warhead moves for a certain distance on the sample feeding main pipe, and the warhead is prevented from stagnating in a pipeline; the secondary air supplementing pipe replaces air supplementing to generate pulse air flow, so that the problem that a warhead is blocked in a pipeline can be effectively solved, and the pneumatic sample feeding machine can work more reliably.
