Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of insect egg collecting devices, and more particularly to a device for collecting lacewing eggs. Background Art
[0002] Chrysopidae are dominant predatory natural enemies of various insect pests in my country's agricultural, forestry, and fruit-producing regions, playing a vital role in controlling aphids, whiteflies, spider mites, and other lepidoptera pests. However, the natural pest control effectiveness of lacewings is often limited by factors such as population size and ecological environment. Therefore, the use of artificial breeding methods and large-scale release techniques to increase lacewing populations in fields and, thereby, enhance their pest control effectiveness is of great practical significance.
[0003] In existing lacewing breeding methods, adults are often raised in cylinders made of materials such as horse manure paper or soft plastic sheets, with built-in feeding sheets, feeding tubes, and food supplements to provide them with food and water. The eggs are oval, with a long diameter of about 1 mm, and are generally green or grass green. The base of the eggs has a flexible, elastic stalk that attaches to the inner wall of the cylinder or to a built-in egg-collecting substrate such as white paper, newspapers, or magazines. To collect the eggs, the stalk is typically cut with scissors, and then the cut eggs are caught with nylon netting for manual collection. Obviously, collecting lacewing eggs requires two separate tools, scissors and nylon netting, which not only increases the number of breeding tools required, but also requires searching for nylon netting or scissors when only scissors or nylon netting are available, making egg collection inconvenient.
[0004] Therefore, how to provide a tool that integrates the functions of scissors and nylon net into one, that is, the tool can not only cut the silk stalks of lacewing eggs, but also has the function of collecting the cut lacewing eggs. It is a problem that technicians in this field urgently need to solve. Utility Model Content
[0005] In view of this, the utility model provides a tool that integrates the functions of scissors and nylon net into one, that is, the tool can not only cut the silk handles of lacewing eggs, but also has a device for collecting lacewing eggs with the function of collecting the cut lacewing eggs. This is not only easy to carry, but also avoids the existing method of collecting lacewing eggs, which requires two separate tools, scissors and nylon net, which not only increases the number of tools to be prepared, but also requires additional search for nylon net or scissors when only scissors or nylon net are available, resulting in inconvenient collection of lacewing eggs.
[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0007] A device for collecting lacewing eggs, comprising:
[0008] A scissor-type handle, wherein the two front ends of the scissor-type handle are connected to a snap-on egg collecting cover, and the open ends of the two egg collecting covers are each provided with a blade for cutting the silk handle on the lacewing eggs;
[0009] A collecting cylinder, one end of which is fixedly connected to a collecting port on the outer wall of one or two of the egg collecting covers;
[0010] A nylon collecting net cylinder, one end of which is detachably connected to the other end of the collecting cylinder.
[0011] It can be seen from the above technical solution that compared with the prior art, the present invention provides a device for collecting lacewing eggs. When collecting lacewing eggs, a scissor-type handle is held and the blades on the two egg collecting covers are closed to cut the silk stalks on the lacewing eggs, and the lacewing eggs fall into the egg collecting cover. When a certain number of lacewing eggs in the egg collecting cover are collected (for example, the two egg collecting covers are opened and the lacewing eggs inside are about to fall out), the lacewing eggs in the egg collecting cover are shaken into a nylon collecting net tube for temporary storage, and then the two egg collecting covers are continued to be used to cut the lacewing egg silk stalks to collect lacewing eggs, and then the lacewing eggs in the egg collecting cover are shaken into the nylon collecting net tube for temporary storage again, and the above steps are repeated. When collection is no longer needed, the nylon collecting net tube is removed from the collecting tube, and the tube mouth of the nylon collecting net tube is tied tightly with a rope to prevent the lacewing eggs inside from falling out.
[0012] The device is suitable for collecting lacewing eggs not only in the wild but also in artificial breeding. The egg collecting cover of the device can not only cut off the silk stalks of the lacewing eggs, but also has the function of temporarily storing the lacewing eggs. In addition, the egg collecting cover is integrated with a nylon collecting net cylinder, which can store the lacewing eggs in the egg collecting cover and provide space for the egg collecting cover to continue collecting.
[0013] Therefore, the device is a tool that integrates the functions of scissors and nylon nets into one, that is, the tool can not only cut the silk handles of lacewing eggs, but also has the function of collecting the cut lacewing eggs. This is not only easy to carry, but also avoids the problem that the existing method of collecting lacewing eggs requires two separate tools, scissors and nylon nets, which not only increases the number of tools to be prepared, but also requires additional search for nylon nets or scissors when only scissors or nylon nets are available, resulting in inconvenient lacewing egg collection.
[0014] Furthermore, connecting rods are fixed to both front ends of the scissor-type handles, and length-adjusting screws are fixed to the outer walls of the two egg-collecting covers, and the length-adjusting screws are threadedly connected to the connecting rods.
[0015] The beneficial effect of adopting the above technical solution is that when the lacewing eggs to be cut are located at a high place and are difficult to cut, the length adjustment screw is rotated out, so that the egg collection cover can be lengthened, making it easier to collect the lacewing eggs at a high place.
[0016] Furthermore, one end of the nylon collecting net tube is threadedly connected to the other end of the collecting tube.
[0017] The beneficial effects of adopting the above technical solution are: easy disassembly and assembly of the nylon collecting net cylinder and the collecting cylinder, and simple and quick operation.
[0018] Furthermore, the two egg collection covers are both made of transparent plastic material.
[0019] The beneficial effect of adopting the technical solution is that it is convenient to observe the number of lacewing eggs collected in the egg collecting cover in real time, so as to shake the lacewing eggs into the nylon collecting net cylinder in time, and provide enough space for the egg collecting cover to continue collecting.
[0020] Furthermore, the scissor-type handle is made of plastic.
[0021] The beneficial effect of adopting the above technical solution is that the device is light and easy to hold and carry. BRIEF DESCRIPTION OF THE DRAWINGS
[0022] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are merely embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on the provided drawings without paying any creative work.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] like Figure 1-Figure 2As shown, the embodiment of the utility model discloses a device for collecting lacewing eggs, comprising:
[0027] A scissor-type handle 1, wherein the two front ends of the scissor-type handle 1 are connected to a snap-on egg collecting cover 2, and the open ends of the two egg collecting covers 2 are each provided with a blade 3 for cutting the silk handle on the lacewing eggs;
[0028] A collecting tube 4, one end of which is fixedly connected to a collecting port on the outer wall of one or both egg collecting covers 2;
[0029] The nylon collecting net tube 5 has one end detachably connected to the other end of the collecting tube 4 .
[0030] In some embodiments, the two front ends of the scissor-type handle 1 are threadedly fixed or welded or integrally formed with a connecting rod 11, and the outer walls of the two egg collecting covers 2 are welded or screwed or integrally formed with a length adjustment screw 21, and the length adjustment screw 21 is threadedly connected to the connecting rod 11. Specifically, one end of the connecting rod 11 has an internal threaded hole, and one end of the length adjustment screw 21 is screwed into the internal threaded hole. Therefore, the length of the length adjustment screw 21 can be adjusted by rotating the length adjustment screw 21, and then the length of the egg collecting cover 2 relative to the connecting rod 11 is adjusted, so that the device is suitable for collecting lacewing eggs located high on the tree trunk.
[0031] Of course, in order to facilitate the quick disassembly and assembly of the nylon collecting net tube 5 and the collecting tube 4, one end of the nylon collecting net tube 5 is connected to the other end of the collecting tube 4 by threaded connection, which makes it easier to quickly break or collect the full nylon collecting net tube 5.
[0032] In some embodiments, the materials of some components of the device are limited. For example, the scissor-type handle 1 is made of plastic, and the two egg collecting covers 2 are both made of transparent plastic. This not only reduces the weight of the device, makes it easy to carry and saves effort in holding, but also allows the user to directly observe the number of lacewing eggs collected inside through the transparent egg collecting cover 2, making it easier to shake the lacewing eggs into the nylon collecting net tube 5 in a timely manner, providing sufficient space for the egg collecting cover 2 to continue collecting.
[0033] When collecting lacewing eggs, the scissor-type handle 1 is held, and the blades 3 on the two egg collecting covers 2 are closed to cut the silk handles on the lacewing eggs, and the lacewing eggs fall into the egg collecting covers 2. When the lacewing eggs in the egg collecting covers 2 are collected to a certain number (for example, the two egg collecting covers are opened and the lacewing eggs inside are about to fall out), the lacewing eggs in the egg collecting covers 2 are shaken into the nylon collecting net tube 5 for temporary storage, and then the two egg collecting covers 2 are continued to be used to cut the lacewing egg silk handles to collect lacewing eggs. Afterwards, the lacewing eggs in the egg collecting covers 2 are shaken into the nylon collecting net tube 5 for temporary storage again, and the above steps are repeated. When collection is no longer needed, the nylon collecting net tube 5 is removed from the collecting tube 4, and the tube mouth of the nylon collecting net tube 5 is tightened with a tie rope to prevent the internal lacewing eggs from falling out.
[0034] The device integrates the functions of cutting the wire handle and collecting lacewing eggs into one. Only one device needs to be carried and used to collect lacewing eggs, thereby avoiding the problem that two separate tools, scissors and nylon nets, are needed for collecting lacewing eggs in the existing method. This not only increases the number of tools to be prepared, but also requires additional searching for nylon nets or scissors when only scissors or nylon nets are available, causing inconvenience in collecting lacewing eggs.
[0035] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. Reference can be made to the common and similar parts between the various embodiments. For the devices disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the method description.
[0036] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
