Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of trichogramma release, especially to a trichogramma paper ball releaser suitable for unmanned aerial vehicle. BACKGROUND

[0002] Trichogramma is the most in-depth researched and most widely applied parasitic enemy insect in the field of global agricultural and forestry pest biological control. In order to improve the release efficiency of trichogramma and solve the release problem, especially the challenge of releasing in high-stalk crops (such as corn and sorghum) and orchards (such as peach and pear), paper and plastic release balls are generally used at present. However, the plastic release ball has environmental protection problems, and the traditional paper release ball needs to be bonded with special glue on the upper and lower two parts, and is pressed by a machine, which is a relatively complex process. In addition, the edge of the bonded release ball is easy to protrude, which is easy to jam when using an unmanned aerial vehicle to release, resulting in uneven release in the field. This not only reduces the work efficiency, but also seriously affects the prevention and control effect of trichogramma. SUMMARY

[0003] The utility model aims at providing a trichogramma paper ball releaser suitable for unmanned aerial vehicle, which will not cause environmental protection problems and.

[0004] To solve the above problems, the utility model provides a trichogramma paper ball releaser suitable for unmanned aerial vehicle, which comprises: an upper shell and a lower shell made of paper material; the upper shell is connected with the lower shell by snap buckle; the top of the upper shell is provided with a plurality of release holes with a hole diameter greater than 0.5mm; the lower shell is a double-layer structure composed of an inner shell and an outer shell; the inner shell is bowl-shaped and is sleeved in the outer shell; the bottom of the outer shell has an inward protrusion, and the bottom of the inner shell is in contact with the inward protrusion of the outer shell; a counterweight is filled in the double-layer structure between the inner shell and the outer shell, so that the release hole is always upward.

[0005] Further, the outer shell of the upper shell and the lower shell in the above-mentioned trichogramma paper ball releaser suitable for unmanned aerial vehicle is made by wet pressing process; the inner shell of the lower shell is made by dry pressing process.

[0006] Further, the inner shell of the lower shell in the above-mentioned trichogramma paper ball releaser suitable for unmanned aerial vehicle extends upward to form an embedding part, and the upper shell has a connecting part corresponding to the embedding part; the embedding part of the lower shell is embedded into the connecting part of the upper shell to form a snap buckle connection.

[0007] Further, the connecting size between the connecting part and the embedding part in the above-mentioned trichogramma paper ball releaser suitable for unmanned aerial vehicle is greater than 2mm.

[0008] Further, the counterweight in the above-mentioned trichogramma paper ball releaser suitable for unmanned aerial vehicle is fine sand.

[0009] Further, the lower shell of the drone-applicable trichogramma paper ball releaser is hemispherical.

[0010] Further, the upper shell of the drone-applicable trichogramma paper ball releaser is conical.

[0011] The above technical solution of the utility model has the following beneficial technical effects:

[0012] After assembly, the outer surface of the releaser is smooth without protruding parts, and due to the double-layer structure at the bottom of the lower shell, the center of gravity of the releaser is located at the bottom of the lower shell by filling the counterweight therein, so that the release hole is always upward, and the trichogramma eggs can drill out of the release hole after hatching.

[0017] To make the purpose, technical scheme and advantages of the utility model more clear and explicit, the utility model is further described in detail below in combination with specific implementation manners and with reference to the drawings.

[0018] The embodiments shown by the utility model are described below in combination with the drawings. Figure 1 The embodiment specifically includes: the upper shell and the lower shell made of paper material, and the upper shell and the lower shell are connected through buckling.

[0019] With reference to Figure 1 In combination with Figure 2The upper shell is provided with a plurality of release holes at the top, each release hole has a hole diameter greater than 0.5mm, and the trichogramma adult can drill out from the release hole after hatching. The upper shell is conical, which can make the upper shell have good pressure resistance. The lower shell is hemispherical, and is a double-layer structure composed of an inner shell and an outer shell. The inner shell is bowl-shaped, and the inner shell is sleeved in the outer shell. In order to better buffer during release and falling, the bottom of the outer shell has an inward protrusion, the bottom of the inner shell is in abutment with the inward protrusion of the outer shell, and the inner shell extends upward to form an embedding part. Correspondingly, the upper shell has a connecting part, the embedding part of the lower shell is embedded into the connecting part of the upper shell to form a buckle connection, and the connecting size between the connecting part and the embedding part is greater than 2mm to ensure the stability of the connection. In order to ensure that the release holes at the top of the upper shell are always upward, fine sand is filled between the inner shell and the outer shell as a counterweight. In this way, after being released by the unmanned aerial vehicle, the upper shell of the embodiment falls into the grass, and the release holes of the upper shell are always upward, so that the trichogramma can fly out of the release holes after hatching.

[0020] During the manufacturing process, the outer shell of the upper shell and the lower shell is manufactured by a wet pressing process, and the inner shell of the lower shell is manufactured by a dry pressing process, so that the manufacturing cost can be reduced. At the same time, since the outer shell of the lower shell is manufactured by a wet pressing process, compared with the inner shell manufactured by a dry pressing process, the outer shell is easy to deform, so that the impact energy can be absorbed by the inward protrusion of the outer shell during release, so that the release device can keep an upright posture after falling to the ground, thereby better protecting the trichogramma eggs inside. The success rate of the unmanned aerial vehicle release is higher than 96%, which can meet the requirements of large-scale release of trichogramma, and since the upper shell and the lower shell are made of regenerated pulp and the counterweight can adopt fine sand, no environmental problems will be caused, and the environment is friendly.

[0021] It should be understood that the above specific embodiments of the present application are only used for illustrative or explanatory purposes of the principles of the present application, and do not constitute a limitation on the present application. Therefore, any modification, equivalent replacement, improvement, etc. made without departing from the spirit and scope of the present application shall be included in the protection scope of the present application. In addition, the appended claims of the present application are intended to cover all changes and modifications falling within the scope and boundary of the appended claims, or the equivalent forms of such scope and boundary.
