Description

Technical Field

[0001] The present invention relates to the technical field of insect collecting equipment, and in particular to an insect collecting device and a use method thereof. Background Art

[0002] When investigating and conducting research on small insects such as thrips, whiteflies, and small flower bugs on mulberry trees, it is often necessary to collect insects in the wild in mulberry gardens. At the same time, if mulberry branches are collected directly, the insects also need to be collected and identified indoors. In these processes, collecting insects with a sucker tube is required in almost every step, and a large number of insect sources are required when conducting experiments. When collecting small insects, the collection tube needs to be repeatedly shaken to transfer the insects out. The process is easy to cause insects to escape, increasing time costs and reducing the efficiency of the experiment. In addition, it is difficult to free your hands to operate during the collection process, or it is difficult to transfer the insects in the sucker device after collection.

[0003] Among the different traditional trematode devices, although there are many electric trematode devices, it is difficult to trematode because there is no trematode tube designed for small insects in the structure, and it cannot be deformed and extended at will. At the same time, the electric trematode device uses dry batteries, which is troublesome to replace batteries and easily causes waste, etc., which affects work efficiency and environment. When transferring insects, it is necessary to shake off the insects in the insect storage bottle continuously, causing the insects to escape in the process. The electric trematode device has not been fully utilized. It has the functions of suction and blowing, and the blowing is utilized. When collecting insects, the more commonly used artificial mouth suction trematode device is easy to suck relatively fine dust and or pollen into the mouth, or when sucking some insects of the stink bug family, it causes discomfort to people due to its special period, or affects health. If a single-mouth suction and blowing air suction ear ball is used, it is inconvenient because its suction mouth needs to be constantly aligned with the catheter of the trematode device, which consumes energy and wastes time, and if the suction ear ball is squeezed, if it is also aligned with the trematode tube, the sucked insects will be blown out.

[0004] In summary, the existing insect collection devices are cumbersome to operate, have low working efficiency, and require a lot of time and labor costs to collect and transfer insects, which is not conducive to further research by operators. Therefore, how to propose an insect collection device and its use method to achieve rapid collection and transfer of insects has become a difficult problem that technicians in this field need to solve urgently.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0043] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0044] Embodiment 1

[0045] As Figures 1-4 shown, this embodiment provides an insect collection device, including a blowing cylinder 1, a power supply device 2, a blowing and suction conversion device 3, a collection cylinder 4 and an insect suction front-end device 5;

[0046] The power supply device 2 is connected to the outer side wall of the air blowing cylinder 1; the air blowing and suction conversion device 3 is rotatably connected to the barrel body of the air blowing cylinder 1; one end of the collection cylinder 4 is detachably connected to the outer side wall of the air blowing cylinder 1 through a cylinder cover 4-1, and the other end is connected to the air outlet cylinder opening of the air blowing cylinder 1 through a first hose 4-2; the insect sucking front-end device 5 is connected to the air inlet cylinder opening of the air blowing cylinder 1, and the insect sucking front-end device 5 communicates with the cylinder cover 4-1 through a second hose 5-1.

[0047] Existing electric insect collection devices do not have an air blowing function. When transferring the collected insects in the laboratory, the operator needs to repeatedly shake the collection tube or collection cylinder to transfer the insects inside. During this process, insects are likely to escape, resulting in an increase in the experimental time cost. The present invention solves the drawback that existing electric insect collection devices do not have an air blowing function through the air blowing and suction conversion device 3. By the mutual cooperation of the air blowing and suction conversion device 3 and the air blowing cylinder 1, the purpose of blowing out the insects in the collection cylinder 4 can be achieved.

[0048] In addition, since the power supply device 2 is connected to the side wall of the air blowing cylinder 1, the external shape structure of the insect collection device of the present invention is in a "T" shape, which is convenient for the operator to grasp the device.

[0049] Specifically, a fan 1-1 is arranged inside the air blowing cylinder 1, and the fan 1-1 is connected to the power supply device 2; a first semi-circular wind baffle 1-5 is arranged near the air outlet cylinder opening of the air blowing cylinder 1;

[0050] A first window 1-2 and a second window 1-3 are opened on the side wall of the air blowing cylinder 1, and the first window 1-2 and the second window 1-3 are respectively located on the left and right sides of the fan 1-1; inward sunken slides 1-4 are arranged at the edges of the first window 1-2 and the second window 1-3, and the inward sunken slides 1-4 are located inside the barrel body of the air blowing cylinder 1; a lever through hole 1-6 is arranged on the side wall of the barrel body of the air blowing cylinder 1 corresponding to the inward sunken slide 1-4;

[0051] The cylinder cover 4-1 is further fixed on the side wall of the air blowing cylinder 1, and the cylinder cover 4-1 is located on the left side of the first window 1-2; the top of the cylinder cover 4-1 is circular, half of the circular top is a solid part, and the other half is a hollow part. The second hose 5-1 communicates with the semi-circular cover top of the solid part, and a pest control net 4-3 is connected to the semi-circular cover top of the hollow part.

[0052] Among them, the mesh number of the pest control net 4-3 is 80 mesh - 120 mesh, which is used to block the insects in the collection cylinder 4 from entering the air blowing cylinder 1. In addition, the second hose 5-1 can also be extended into the collection cylinder 4, and the extended length exceeds half of the cylinder length of the collection cylinder 4. The function of this setting is to prevent the insects in the collection cylinder 4 from escaping from the second hose 5-1.

[0053] In specific implementation, the fan blades of the fan 1-1 are controlled to be 6 or 9, and the rotation speed of the fan 1-1 is controlled within 15000 rpm - 25000 rpm. This rotation speed can provide stable suction power for the insect collection device. If the rotation speed is too large or too small, it will have a certain impact on the effect of sucking insects. If it is too small, insects cannot be sucked, and if it is too large, the insect body will be damaged.

[0054] Specifically, the power supply device 2 includes a battery 2-1, a battery compartment 2-2 and a control switch 2-3. The battery compartment 2-2 is connected to the side wall of the air blowing cylinder 1. The battery 2-1 is installed inside the battery compartment 2-2. The control switch 2-3 is connected to the battery compartment 2-2. A charging port 2-4 is further provided on the battery compartment 2-2. The bottom of the battery compartment 2-2 is threadedly connected with a cover 2-5.

[0055] Among them, the connection position of the control switch 2-3 and the battery compartment 2-2 can be set on the side close to the air blowing cylinder 1, so that the insect collection device has a gun rack structure, which is convenient for the operator to operate.

[0056] Among them, the battery 2-1 is a battery pack, and this battery pack is any one of a lithium battery, a nickel-metal hydride battery, a lead-acid battery or a lithium iron phosphate battery. The output voltage of the battery 2-1 is controlled to be 5V - 9V, and the output current is controlled to be 1A - 2A.

[0057] Specifically, the blowing and suction conversion device 3 includes a lever 3-1, a first cylindrical baffle 3-2 and a second cylindrical baffle 3-3. The first cylindrical baffle 3-2 and the second cylindrical baffle 3-3 are both rotatably connected to the inside of the air blowing cylinder 1 through the recessed slideway 1-4. The position of the first cylindrical baffle 3-2 corresponds to the position of the first window 1-2; the position of the second cylindrical baffle 3-3 corresponds to the position of the second window 1-3;

[0058] Both ends of the lever 3-1 are respectively connected to the first cylindrical baffle 3-2 and the second cylindrical baffle 3-3. The lever 3-1 passes through the lever through-hole 1-6 and is located outside the air blowing cylinder 1;

[0059] The edge of the second cylindrical baffle 3-3 is connected with a second semi-circular wind baffle 3-5, and the second semi-circular wind baffle 3-5 fits against the first semi-circular wind baffle 1-5;

[0060] Window parts are respectively opened on the barrel bodies of the first cylindrical baffle 3-2 and the second cylindrical baffle 3-3. The sizes of the window parts respectively correspond to the sizes of the first window 1-2 and the second window 1-3; the two window parts are arranged in a staggered manner and are both connected with dust-proof gauze 3-4. Among them, the mesh number of the dust-proof gauze 3-4 is 20 - 40 meshes.

[0061] Specifically, one side of the collection cylinder 4 is detachably connected to the cylinder cover 4-1 by a thread, and the other side is connected with a suction-proof insect net 4-4.

[0062] Among them, the mesh number of the suction-proof insect net 4-4 is 80 mesh - 120 mesh, which is used to prevent insects in the collection cylinder 4 from escaping through the first hose 4-2. The collection cylinder 4 is made of hard transparent plastic material, which is convenient for the operator to observe the collection situation of insects in the collection cylinder 4.

[0063] Specifically, the insect suction front-end device 5 includes a conical sleeve 5-2. One end of the conical sleeve 5-2 is sleeved on the air inlet of the air blowing cylinder 1, and the other end is connected to the second hose 5-1.

[0064] Among them, the connection mode between the conical sleeve 5-2 and the second hose 5-1 is a sealed connection, which can avoid air being inhaled from the connection gap between the second hose 5-1 and the conical sleeve 5-2 when the fan 1-1 is working. The diameter of the second hose 5-1 is controlled to be 0.3 - 0.80 cm, and the material of the second hose 5-1 is transparent plastic, which is convenient for the operator to observe the collection situation of insects.

[0065] Specifically, a chamber partition plate 1-7 is also arranged in the air blowing cylinder 1, and the position of the chamber partition plate 1-7 corresponds to the boundary position between the solid part and the hollow part of the cylinder cover 4-1.

[0066] When the fan 1-1 is working, if air is inhaled from the connection gap between the second hose 5-1 and the conical sleeve 5-2, the second hose 5-1 will not be able to provide sufficient suction to suck insects. The chamber partition plate 1-7 is used to ensure that even if there is a gap at the connection between the second hose 5-1 and the conical sleeve 5-2, air will only be inhaled from the second hose 5-1.

[0067] Specifically, strap loops 1-8 are respectively connected to both sides of the barrel body of the air blowing cylinder 1.

[0068] Among them, the strap loops 1-8 are used to connect the straps, which is convenient for the operator to carry the insect collection device on the body through the straps and convenient for the operator to control the insect collection device.

[0069] Embodiment 2

[0070] This embodiment provides a usage method for the insect collection device described in Embodiment 1, and the method includes the following steps:

[0071] S1: Adjust the device before catching insects, and connect the collection cylinder 4 to the cylinder cover 4-1;

[0072] S2: The adjustment device is in the suction mode. Use the lever 3-1 to make the first cylinder baffle 3-2 block the first window 1-2, and make the window part of the second cylinder baffle 3-3 coincide with the second window 1-3. At this time, the second semi-circular wind baffle 3-5 and the first semi-circular wind baffle 1-5 cooperate to block the air outlet of the air blowing cylinder 1; air is inhaled from the second hose 5-1, flows through the collection cylinder 4, the insect net 4-3 and the air blowing cylinder 1 in sequence, and flows out from the second window 1-3;

[0073] S3: Catch insects. Turn on the control switch 2-3 to make the fan 1-1 rotate for blowing operation to provide suction for the second hose 5-1. At this time, aim the second hose 5-1 at the insects so that the insects are sucked into the collection cylinder 4;

[0074] S4: Prepare for transferring insects. Separate the collection cylinder 4 from the cylinder cover 4-1 and align the collection cylinder 4 with the insect collection box;

[0075] S5: The adjustment device is in the blowing mode. Use the lever 3-1 to make the window part of the first cylinder baffle 3-2 coincide with the first window 1-2, and make the second cylinder baffle 3-3 block the second window 1-3. At this time, the second semi-circular wind baffle 3-5 coincides with the first semi-circular wind baffle 1-5, exposing the air outlet of the air blowing cylinder 1; air is inhaled from the insect net 4-3 and the first window 1-2, and blown into the collection cylinder 4 through the first hose 4-2 and the anti-fluke net 4-4;

[0076] S6: Transfer insects. Turn on the control switch 2-3 to make the fan 1-1 rotate for blowing operation to provide blowing force for the first hose 4-2. At this time, blow the insects from the collection cylinder 4 into the insect collection box.

[0077] There are various pests on mulberry trees. Among them, the mulberry thrips is the main mulberry pest. Conduct a collection experiment on the mulberry thrips in the outdoor mulberry orchard. The experimental device uses a suction tube, an ear bulb type suction device and the device provided by the present invention to collect the mulberry thrips respectively. After collecting by different methods, the insects are transferred to a collection bottle filled with alcohol and taken back to the laboratory for statistical counting. The collection time is set to 1 min, 5 min, and 10 min respectively. The collection quantities of the mulberry thrips by different suction devices outdoors are shown in the following table:

[0078] Table 1

[0079]

[0080]

[0081] As can be seen from the data in the table, there are obvious differences in the collection efficiency of Pseudodendrothrips mori in mulberry fields within the same time interval. The number of thrips collected at 1 minute, 5 minutes, and 10 minutes after starting to suck insects was counted. The more insects collected within the same time, the higher the efficiency. Therefore, the collection efficiency at 10 minutes: the suction and blowing device for sucking insects > the mouth-suction type for sucking insects > the rubber bulb type for sucking insects. This device is more suitable for working for a relatively long time compared to the mouth-suction type for sucking insects, and the collection efficiency is basically stable. The mouth-suction type for sucking insects is not suitable for working for a long time because it relies entirely on manual suction, and the rubber bulb type for sucking insects has the lowest efficiency due to cumbersome operation. At the same time, a large amount of dust will enter the mouth during the operation of the mouth-suction type for sucking insects, which will pose a threat to human health.

[0082] Collect the Drosophila melanogaster reared with bananas indoors, and transfer the collected Drosophila melanogaster to the insect collection box. Mainly count the time required to collect 100 and 200 adult Drosophila melanogaster. The collection devices are a suction tube, a rubber bulb type suction device, and the device provided by the present invention respectively. The collection results are shown in the following table:

[0083] Table 2

[0084]

[0085] As can be seen from the data in the table, when sucking the same number of insects, the collection method using the suction and blowing device in this invention requires less time. There will be no more dust and the smell of reared insects during the process of collecting insects, which will cause discomfort to people. At the same time, it has obvious advantages in using when sucking a relatively large number of insects, is suitable for long-term use, and does not consume more manpower.

[0086] The above experiments show that this suction and blowing collection method has very obvious advantages in specific experiments and sucking insects. It can greatly increase the number of insects sucked within the same time and is applicable in various environments. It is suitable for collecting insects for a long time and in large quantities regardless of the environment, and there are no cumbersome operation steps during the collection process. Whether collecting insects on outdoor plants or in indoor insect cages, it can effectively avoid the threat of the smell and dust of collecting insects to human health. It improves work efficiency, is applicable in different experiments, and can be used for different insects.

[0087] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0088] The above-described embodiments are only descriptions of the preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
