TECHNICAL FIELD
[0001] The utility model relates to the technical field of grain storage pest control, and particularly relates to a phosphide aluminum pesticide application device for internal grain piles. BACKGROUND
[0002] When phosphine fumigation is carried out, phosphide aluminum tablets need to be put into the grain pile, and the phosphide aluminum tablets will react with water vapor in the air to generate phosphine gas. When the height of the grain pile exceeds 3 meters, the phosphine generated by the phosphide aluminum tablets put on the grain surface cannot penetrate the grain pile, resulting in poor control effect on pests in the deep layer of the grain pile. Therefore, tools are needed to realize pesticide application in the deep layer of the grain pile. At present, when phosphide aluminum is put into the deep layer of the grain pile, a probe pipe is usually used for pesticide application.
[0003] The probe pipe comprises a pipe body, and the side wall of the pipe body has a hole. After the probe pipe is inserted into the grain pile, the phosphide aluminum tablets are put into the probe pipe from the top, and then the top end is closed. Water vapor in the air enters the hole in the side wall of the probe pipe and reacts with the phosphide aluminum to generate phosphine. The main problem of the existing probe pipe pesticide application is that the phosphide aluminum tablets cannot directly contact the bulk grain, so the probe pipe cannot be pulled out during the whole process of releasing phosphine gas by the reaction of the phosphide aluminum tablets. This results in that the probe pipe cannot be repeatedly used at multiple positions, and a probe pipe is needed for each pesticide application position, which leads to high cost of pesticide application equipment.
