Insect sucking device

Abstract

The invention relates to an agricultural machinery mainly used for physical disinsection of crops. The agricultural machinery comprises a power source, a fan, an insect stopping net, an air sucking head, an air feeding mechanism, an air processor and an insect storage box, wherein the fan is an air blower in transmission connection with the power source; the insect stopping net is arranged at an air outlet of the air processor; the air processor is a whirl box of the air; the air outlet of the air processor is connected with an air inlet of the air blower; the insect storage box is arranged below the air processor and communicated with the air processor; the air sucking head comprises an air gathering cover; an air outlet of the air sucking head is connected with the air inlet of the air processor by a pipe; the air feeding mechanism comprises at least one air feeding pipe; an air inlet of the air feeding mechanism is connected with an air outlet of the air blower by a pipe; a cover opening of the air sucking head is arranged above the crop downward; and the air feeding pipe of the air feeding mechanism is arranged at the side face of the crop. The agricultural machinery provided by the invention has the advantages of simple equipment and high disposable cleaning rate and can be applied to physical disinsection of large-area grow plants.

Description

technical field [0001] The invention relates to an agricultural machine, which is mainly used for physical deworming of crops. 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. ZL 200520122767.8, ZL02264841.0, 200810228958.0 and 200810031846.6. Among them, the common feature of ZL 200520122767.8, ZL02264841.0, and 200810228958.0 is the use of suction fan negative pressure trematodes. ZL02264841.0 and 200810228958.0 did not ...

Problems solved by technology

Among them, the common feature of ZL 200520122767.8, ZL02264841.0, and 200810228958.0 is the use of suction fan negative pressure trematodes. ZL02264841.0 and 200810228958.0 did not make use of the exhaust air characteristics of the equipment. Due to the limitation of small equipment, the air supply port and the suction port are too small, and there is not enough collection capacity after the flying insects are disturbed and scattered; the common defects of the above three technical solutions include: 1. The suction port is narrow, suitable for spot suction, and cannot be applied to Large-scale farmland insect removal, 2. The suction is small, and the removal rate for multi-legged insects is poor. 3. For flying insects, the narrow suction port has no practical effect when used for large-scale farmland insect removal.

Patent application 200810031846.6 is a technical solution proposed to be applied to large-scale commercial crops of shrubs to remove insects. However, the applicant believes that there are defects in the design idea: 1. The patent application proposes "using wind to blow away and blow some pests", and at the same time Considering the strong adhesion of multi-legged insects to plants, they proposed to "use the scouring force generated by spray water to wash away some pests". However, they did not consider that insects stuck to water are more difficult to be blown away by wind, and insects with water are more difficult to blow away. The self-weight is large, and it is less likely to be blown or washed into the insect net when it is blocked by branches and leaves, and the insects that are not collected by the insect net may still cause harm to the crops, and the pest removal rate is not high; 2. The application is to apply wind and water from one side of the shrub, and stretch the net to collect from the other side, so the effect on the windward and water side may be better, while the effect on the leeward and backwater side will be greatly reduced. To achieve the desired effect, the equipment must be Turn to the other side and operate again, resulting in labor-intensive, time-consuming, and cost-increasing defects
