The pesticide can be added into the medicine storage box through the liquid inlet pipe 16, and the liquid inlet pipe 16 can be sealed through the second sealing plug 17.

[0041] When changing the capacity of the medicine storage box, first, the electric push rod 1101 is used to make the locking block 1103 on the cross plate 1102 separate from the locking groove 10. Then, the number of the auxiliary boxes 7 on the left side of the main box 2 is changed, and the T-shaped groove 9 on the auxiliary box 7 is made to contact the T-shaped column 6. Then, the locking groove 10 is aligned with the locking block 1103, and through the electric push rod 1101, the locking block 1103 is inserted into the locking groove 10. At this time, through the cooperation of the locking block 1103, the locking groove 10, the T-shaped column 6 and the T-shaped groove 9, the auxiliary box 7 can be fixed on the left side of the main box 2. At the same time, the main box 2 and the auxiliary box 7 can be communicated through the three-way pipe 12 and the round hole 15, and the adjacent auxiliary boxes 7 can be communicated through the three-way pipe 12 and the threaded cylinder 13. Then, the first sealing plug 14 is screwed into the leftmost threaded cylinder 13. At this time, through the first sealing plug 14, the liquid medicine in the main box 2 and the auxiliary box 7 cannot be discharged through the leftmost three-way pipe 12.

[0042] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
