Abstract
Description
Technical Field
[0001] This invention relates to the field of mango pest control technology, and more particularly to a device for controlling fruit flies on highly mature mangoes. Background Technology
[0002] Currently, with the development of my country's economy, the increase in people's income and the continuous improvement of living standards, people are paying more attention to the impact of high-quality mangoes on their taste experience, and the market demand for high-quality mangoes that are 80% ripe or more is strong.
[0003] However, during the summer and autumn when mangoes ripen, fruit fly and bird damage are severe. Once mangoes are over 60% ripe, their fragrance attracts large numbers of adult fruit flies. These flies use their ovipositors to pierce the mango peel and lay eggs. The hatched larvae then congregate in the flesh to feed. The affected areas of the peel first develop color, then exude gum, causing the peel to sink and rot, leading to fruit drop. Damage can exceed 40% in severe cases. Even mangoes unaffected by fruit flies, once colored, still attract birds with their fragrance, severely hindering the development of high-quality mangoes. This results in extremely low yields, high costs, and poor marketability, failing to meet current demand for high-quality mangoes. Summary of the Invention
[0004] The purpose of this invention is to provide a fruit fly control device for highly mature mangoes, thereby solving the aforementioned technical problems in the prior art.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] The present invention discloses a fruit fly control device for highly mature mangoes, comprising side columns, a central column, a flipping device, and an insect-proof net. The flipping device includes a positioning column, a fixing block, a rotating rod, and a pressing plate. Guide blocks are fixed to the upper ends of the side columns and the central column. A steel wire rope is slidably connected inside the guide block. Weights are provided at both ends of the steel wire rope. The rotating rod is rotatably connected to the surface of the central column. The positioning column is fixed to the other end of the rotating rod relative to the central column.
[0007] The extrusion plate is slidably connected to the surface of the rotating rod, and fixing holes are provided on the surfaces of the rotating rod and the extrusion plate;
[0008] The fixing block is rotatably connected to the fixing hole. Rotating the fixing block allows the extrusion plate to be removed. One end of the insect net is placed between the positioning post and the extrusion plate. The extrusion plate presses the insect net onto the surface of the positioning post. The extrusion plate is fixed by the fixing block. After rotating the rotating rod, the rotating rod rotates relative to the central column. At this time, the positioning post drives the insect net to move to the other end. The insect net can be removed and pulled to both sides to unfold it on the wire rope. The insect net stably covers the surface of the wire rope.
[0009] Preferably, the surface of the fixing block is provided with a screw, and the screw is rotatably connected to the fixing hole through a thread.
[0010] Preferably, the surface of the extrusion plate is arc-shaped and the arc-shaped surface of the extrusion plate is in contact with the surface of the positioning post.
[0011] Preferably, the upper end of the guide block is provided with a protrusion and a roller is rotatably connected to the middle of the protrusion, so that the moving insect net can drive the roller to rotate.
[0012] Preferably, the guide block has balls inside, and the balls are in contact with the surface of the wire rope.
[0013] Compared with existing technologies, the fruit fly control device for highly mature mangoes provided by this invention has the following beneficial technical effects:
[0014] This invention uses a flipping device to drive the insect-proof net to rotate, which speeds up the laying of the insect-proof net. The steel wire rope is fixed by a weight to avoid damage caused by the steel wire rope being too taut, and at the same time, it is convenient to replace the steel wire rope. The roller rotates with the insect-proof net to ensure the integrity of the insect-proof net during laying. Attached Figure Description
