Shoulder-hanging drug-free pest-killing machine

Abstract

The invention discloses a shoulder-hanging drug-free pest-killing machine. The shoulder-hanging drug-free pest-killing machine comprises a sucking disc, an air transmission pipeline, an air suction pipeline and a shoulder-hanging box body. The shoulder-hanging box body is internally provided with an airflow generating device and a pest collection box. The center of the sucking disc is provided with a sucking disc opening. The air suction pipeline is connected with the sucking disc opening and the pest collection box.The sucking disc is composed of an inner wall and an outer wall. Multiple air flow openings are arranged in the inner wall. Each air flow opening is provided with an air-flow jet pipe facing upward or an air-flow jet pipe facing downward. The shoulder-hanging drug-free pest-killing machine has following beneficial effects: pesticides are not allowed to be used for sprinkling the rice field; as a result, pesticide cost is saved and pesticide residuals of crops are greatly minimized; by taking different schemes, pests at different positions of seedlings are killed by collecting into the pest collection box or spraying water of the rice field; and significant pest-killing effect is exerted by actual operation.

Description

technical field [0001] The invention relates to the technical field of small-scale agricultural plant protection equipment, and more specifically relates to a shoulder-mounted non-drug exterminator. Background technique [0002] With the increasing attention to food safety, drug residues in crops have gradually become an important factor affecting the quality of crops. At present, the deworming of large-scale crops in my country mainly relies on pesticides, resulting in high drug residues in large-scale crops. After a patent search, we found eleven patents or patent applications involving negative pressure physical pest removal, two patents or patent applications for wind-powered pest removal, and four patents or patent applications for the purpose of serving agricultural production, respectively. ZL200520122767.8, ZL02264841.0, 200810228958.0 and 200810031846.6. Among them, the common feature of ZL200520122767.8, ZL02264841.0, and 200810228958.0 is the use of suction fan ...

Problems solved by technology

Among them, the common feature of ZL200520122767.8, ZL02264841.0, and 200810228958.0 is the use of suction fan negative pressure trematodes. ZL02264841.0 and 200810228958.0 did not utilize the exhaust air characteristics of the equipment. Although 200520122767.8 utilized the exhaust air, it was burdened. Due to the limitation of small equipment, the air supply port and the suction port are too small. After the flying insects are disturbed and scattered, there is not enough collection capacity. The wind generated by the manual wind is not enough to collect the disturbed flying insects.

At present, there is no drug-free killing machine for the pests in the paddy field. The pests in the paddy field are mainly winged moths such as the adults of the three stem borers. These pests are mainly concentrated in the middle and lower parts of the seedlings. In this practice, we decided to adopt different schemes to eliminate the pests in different positions on the seedlings
