Agricultural greenhouse pesticide conveying and spraying device for tomato leaf mold treatment

Abstract

The invention discloses an agricultural greenhouse pesticide conveying and spraying device for tomato leaf mold treatment, and belongs to the technical field of greenhouse planting equipment. The agricultural greenhouse pesticide conveying and spraying device comprises a greenhouse body, a sliding rail and a sliding table. The sliding rail is fixedly installed at the top of an inner cavity of the greenhouse body, the sliding table is arranged on the outer wall of the sliding rail, an electric telescopic rod is fixedly installed on the outer wall of the bottom of the sliding table, and a spraying plate is fixedly installed at the bottom end of the electric telescopic rod. Spraying heads are evenly arranged on the outer wall of the bottom of the spraying plate, and a guiding device is arranged on the outer wall of the spraying plate. Pesticide liquid blocked and sprayed down by blades at the tops of tomatoes is collected by a collection box, the pesticide liquid is discharged from the holes, the blades rotate to strike and guide the pesticide liquid flowing out from the holes, so that the pesticide liquid is dispersed by a dispersion filter screen and then sprayed onto the tomatoes again, the waste degree of the pesticide liquid is reduced, and the blades at the middle and lower parts of the tomatoes can be in more sufficient contact with the pesticide, so that the pesticide is sprayed more uniformly.

Description

technical field [0001] The invention relates to the technical field of greenhouse planting equipment, in particular to an agricultural greenhouse pesticide conveying and spraying device for controlling tomato leaf mold. Background technique [0002] During the process of planting tomatoes in the greenhouse, it is necessary to control the pests and pathogens of the tomatoes. Now when the spraying device is used to control the leaf mold of the tomatoes, in order to make the pesticide spray evenly, the tomato is generally sprayed from the top of the tomato through the atomizing nozzle. Spraying pesticides as a whole, however, in the process of spraying pesticides, due to the obstruction and guidance of the leaves on the top of the tomato, some pesticides will flow down from around the top of the tomato, and the pesticides sprinkled from the left and right sides will directly enter the ditch in the planting area In the middle of the road, resources are wasted, and due to the shi...

[0002] During the process of planting tomatoes in the greenhouse, it is necessary to control the pests and pathogens of the tomatoes. Now when the spraying device is used to control the leaf mold of the tomatoes, in order to make the pesticide spray evenly, the tomato is generally sprayed from the top of the tomato through the atomizing nozzle. Spraying pesticides as a whole, however, in the process of spraying pesticides, due to the obstruction and guidance of the leaves on the top of the tomato, some pesticides will flow down from around the top of the tomato, and the pesticides sprinkled from the left and right sides will directly enter the ditch in the planting area In the middle of the road, resources are wasted, and due to the shielding effect of the top leaves of the tomato, some leaves in the middle and lower areas of the tomato cannot fully contact with the pesticide, resulting in a decrease in the uniformity of pesticide spraying, which affects the control effect of tomato leaf mold. , we propose an agricultural greenhouse pesticide conveying and spraying device for the control of tomato leaf mold
