Description

Technical Field

[0001] The invention belongs to the technical field of insect feeding and relates to an aphid feeding device. Background Art

[0002] Aphids, a collective term for the superfamily Aphidoidea in the order Hemiptera, are a group of herbivorous insects. Due to their short reproductive cycle, diverse diet, and ease of feeding, aphids have become a model species for studying plant-insect interactions. Common aphids that infest fruit trees include the citrus aphid, Schizaphis citri, cotton aphid, and green peach aphid, while those that infest vegetables primarily include green peach aphid, radish aphid, melon aphid, cabbage aphid, and bean aphid. Aphids are highly destructive to vegetables and fruit trees, and if left uncontrolled, they can lead to significant declines in yield and quality. Pest control researchers often need to rear a variety of insects in the laboratory to obtain a sufficient number of insect colonies for laboratory research, such as physiological and biochemical experiments on insects and bioassays of the toxic effects of pesticides on pests. To obtain sufficient insect colonies, specialized insect feeders are required. Different insects have varying physiological and biochemical characteristics, body size, and habits, necessitating different feeders. Due to the small size and strong reproductive capacity of aphids, it is necessary to prevent aphids from escaping from the experimental environment during feeding to prevent them from invading and contaminating other experimental materials.

[0003] A Chinese patent discloses a feeding device for aphid populations [authorization publication number CN 206641233U], which includes a cylindrical transparent feeding tube with openings at both ends. A cylindrical plant growth block is provided at one end of the feeding tube, and a cylindrical sponge sealing layer is installed at the other end. A nutrient layer is provided inside the plant growth block, and a plant socket is arranged at the top center of the plant growth block. Fresh crop leaves are inserted into the plant socket, which can prevent aphids from escaping from the experimental environment to a certain extent.

[0004] However, the aforementioned feeding device requires replacement of fresh crop leaves and replenishment of plant nutrient solution every 7-8 days. This process inevitably requires opening the feeding device, which creates the possibility of aphids escaping from the feeding device. Furthermore, the existing feeding device has a large internal cavity, making it difficult to collect aphids scattered within, and this can also cause aphids to escape during the collection process. Summary of the Invention

[0005] The purpose of the present invention is to solve the above problems in the existing technology and to provide an aphid feeder which can effectively prevent aphids from escaping.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] An aphid feeder comprises a box body with an inner cavity, a feeding port connected to the inner cavity is opened on the top of the box body, a fixed cover plate parallel to the outer top surface of the box body is provided directly above the feeding port, a movable channel is formed between the fixed cover plate and the outer top surface of the box body, a hollow barrel is provided in the movable channel, the barrel is connected to a movable cover plate which fits the inner top surface of the box body, when the barrel and the feeding port are in a non-connected state, the movable cover plate seals the lower end of the feeding port, when the barrel and the feeding port are connected, the fixed cover plate seals the upper end of the barrel, and at this time the movable cover plate is away from the feeding port.

[0008] Aphids are raised in the inner cavity of a box made of transparent material, and the growth of aphids in the inner cavity can be observed from outside the box. When there is no need to add fresh crop leaves to the inner cavity, the barrel and the discharge port are in a non-connected state. At this time, the movable cover seals the lower end of the discharge port, and aphids cannot escape from the discharge port. When fresh crop leaves need to be added to the inner cavity, the fresh crop leaves are first placed into the hollow barrel, and then the barrel is moved along the outer top surface of the box until it is directly above the discharge port. At this time, the discharge port is connected to the barrel, and the fresh crop leaves in the barrel fall into the inner cavity through the discharge port. At this time, the fixed cover covers the upper end of the barrel to prevent aphids from escaping.

[0009] In the above-mentioned aphid feeder, a guide hole is opened on the side of the box body, which is slidably matched with the movable cover plate. One end of the movable cover plate passes through the guide hole and is connected to the barrel through a connecting plate. A limit plate 1 is provided between the movable cover plate and the connecting plate. When the limit plate 1 rests on the box body, the movable cover plate seals the lower end of the drop port.

[0010] The guide hole extends along the length of the movable cover plate, and under the guidance of the guide hole, the movable cover plate can only move back and forth in one direction. The position of the connecting plate is limited by a pair of limit plates, which can facilitate the rapid positioning of the barrel.

[0011] In the above-mentioned aphid feeder, the fixed cover is fixed to the box body through a bracket, and the bracket is provided with a second limiting plate for limiting the barrel. When the barrel abuts against the second limiting plate, the barrel is connected to the drop port.

[0012] Limiting plates 1 and 2 allow for rapid positioning of the barrel at two locations, reducing the barrel positioning time to less than the aphid's reaction time and preventing aphids from escaping during the positioning process. To allow for ventilation, small holes can be provided in the box, or in the movable cover and connecting plate. To facilitate barrel movement, a handle is provided on the end of the connecting plate away from the barrel.

[0013] In the above-mentioned aphid breeding device, the box body is provided with a collecting channel communicating with the inner cavity, the end of the collecting channel away from the inner cavity is connected to a collecting box, the collecting box is provided with an aphid collecting assembly, and the collecting channel is provided with a baffle for cutting off the collecting channel.

[0014] The diameter of the collection channel gradually decreases from one end near the inner cavity to the other. When aphids need to be collected, the baffle is opened, connecting the inner cavity of the box with the collection box through the collection channel, and the aphids are collected by the aphid collection assembly. During the breeding process, the baffle blocks the collection channel, preventing aphids in the inner cavity from escaping through the collection channel.

[0015] In the above-mentioned aphid feeder, the collection box has a longitudinally extending collection cavity, the end of the collection channel away from the inner cavity is connected to the upper part of the collection cavity, the lower side of the collection cavity is provided with an opening connected to the collection cavity, and the aphid collection assembly is inserted into the collection cavity through the opening.

[0016] Aphids enter the collection cavity from the collection channel and then enter the aphid collection component. The aphid collection component is then taken out from the opening, which facilitates the rapid transfer of the aphids.

[0017] In the above-mentioned aphid feeder, the aphid collecting assembly includes a transfer box with an opening on the top and a sliding cover plate slidably arranged at the opening of the transfer box. When the transfer box is inserted into the collecting cavity through the opening, the upper part of the collecting cavity is connected to the opening of the transfer box.

[0018] The transfer box is slidably matched with the opening. When the transfer box is inserted into place through the opening, the transfer box completely blocks the opening, and the aphids in the collection box will not escape from the opening. In order to facilitate the movement of the transfer box, a handle is provided at the outer end of the transfer box.

[0019] In order to facilitate the movement of the sliding cover plate, guide grooves are respectively provided on both sides of the transfer box. The two guide grooves are arranged opposite to each other, and the sliding cover plate is slidably arranged in the two guide grooves.

[0020] In the aphid breeding device, a phototactic lamp is provided in the collecting box.

[0021] When aphids need to be collected, the baffle and the phototaxis lamp are opened, and the aphids are attracted to the transfer box by utilizing their phototaxis. When the transfer box is taken out from the opening, the sliding cover is moved to cover the opening.

[0022] In the above-mentioned aphid breeding device, the transfer box is made of transparent material, the phototaxis lamp is arranged below the transfer box, and the upper part of the collection cavity is provided with a reflector for reflecting the light of the phototaxis lamp into the inner cavity of the box.

[0023] Aphids are first attracted by the light reflected by the reflector. When they reach the upper part of the collection chamber, they are attracted by the light of the phototactic lamp located below, which is conducive to the aphids entering the transfer box.

[0024] In the above-mentioned aphid breeding device, a spherical rotating cavity is provided on the top of the collection box, a rotating ball rotates in the rotating cavity, the reflector is connected to the lower part of the rotating ball through a connecting rod, and an operating rod is provided on the rotating ball.

[0025] The outer diameter of the rotating ball is greater than the thickness of the top plate of the collection box. The rotating cavity is set through the top plate of the collection box. The rotating ball can rotate in the rotating cavity but cannot escape from the rotating cavity. When the operating lever is rotated, the rotating ball can be driven to rotate, thereby driving the reflector to rotate, so that the reflected light can illuminate every corner of the inner cavity of the box, or only illuminate the designated position according to needs, so as to facilitate the collection of aphids at the designated position.

[0026] In the aphid feeding device, the rotating ball is wrapped with a rubber layer.

[0027] The friction with the rotating cavity is increased, and when the rotating ball is rotated to a specified position, the rotating ball can be kept in the current state through the friction force.

[0028] In the above-mentioned aphid breeding device, a sponge layer is provided at the inner bottom of the box body, a water supply hole is provided below the sponge layer and passes through the bottom of the box body, a water tray is provided below the box body, and the water supply hole is connected to the water tray.

[0029] As needed, water can be added to the chamber through the water tray and water supply hole to maintain humidity and prolong the freshness of fresh crop leaves. The water should be added below the top surface of the sponge layer. To facilitate cleaning of internal waste, the bottom of the chamber is open; simply remove the chamber when cleaning is required.

[0030] Compared with the existing technology, the aphid feeder has the following advantages: the provided barrel, movable cover and fixed cover can effectively prevent aphids located in the inner cavity of the box from escaping; the operation is simple when feeding fresh crop leaves, and no aphids will escape during the feeding process; the aphid collecting component can effectively collect aphids, and the rotatable reflector can illuminate light to every corner of the inner cavity of the box, and can also illuminate only designated positions according to needs, making it convenient to collect aphids at designated positions.

DETAILED DESCRIPTION

[0038] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0039] like Figure 1 and Figure 2 The aphid feeder shown includes a box body 1 with an inner cavity. The box body 1 is rectangular and made of transparent material such as glass or transparent plastic. A feeding port 2 communicating with the inner cavity is provided on the top of the box body 1. A fixed cover plate 3 parallel to the outer top surface of the box body 1 is provided just above the feeding port 2. Both ends of the fixed cover plate 3 are fixed to the box body 1 by brackets. A movable channel 4 is formed between the fixed cover plate 3 and the outer top surface of the box body 1. A hollow material barrel 5 is provided in the movable channel 4. The material barrel 5 can slide on the outer top surface of the box body 1. Figure 1 、 Figure 2 and Figure 3 As shown, the barrel 5 is connected to a movable cover plate 6 that fits with the inner top surface of the box body 1. When the barrel 5 and the blanking port 2 are in a non-connected state, the movable cover plate 6 seals the lower end of the blanking port 2. When the barrel 5 and the blanking port 2 are connected, the fixed cover plate 3 seals the upper end of the barrel 5. At this time, the movable cover plate 6 is away from the blanking port 2.

[0040] When fresh crop leaves do not need to be added to the inner cavity, the barrel 5 and the discharge port 2 are in a disconnected state. At this time, the movable cover 6 seals the lower end of the discharge port 2, preventing aphids from escaping from the discharge port 2. When fresh crop leaves need to be added to the inner cavity, the fresh crop leaves are first placed into the hollow barrel 5. The barrel 5 is then moved along the outer top surface of the box body 1 until it is directly above the discharge port 2. At this time, the discharge port 2 and the barrel 5 are connected, and the fresh crop leaves in the barrel 5 fall into the inner cavity through the discharge port 2. At this time, the fixed cover 3 covers the upper end of the barrel 5 to prevent aphids from escaping.

[0041] like Figure 3 As shown, the side of the housing 1 is provided with a guide hole 7 that slidably engages with the movable cover 6. The guide hole 7 is rectangular and extends along the length of the movable cover 6. Under the guidance of the guide hole 7, the movable cover 6 can only move back and forth linearly in one direction. One end of the movable cover 6 extends through the guide hole 7 and is connected to the barrel 5 via a connecting plate 8. A limit plate 9 is provided between the movable cover 6 and the connecting plate 8. When the limit plate 9 abuts against the housing 1, the movable cover 6 seals the lower end of the blanking port 2, facilitating rapid positioning of the barrel 5.

[0042] like Figure 1-3 As shown, the bracket is equipped with a second limiting plate 10 for limiting the position of the barrel 5. When the barrel 5 abuts against the second limiting plate 10, the barrel 5 communicates with the discharge port 2. The first limiting plate 9 and the second limiting plate 10 allow the barrel 5 to be quickly positioned at two positions, reducing the positioning time of the barrel 5 to less than the reaction time of aphids and preventing aphids from escaping during the positioning process. To facilitate the movement of the barrel 5, a handle is provided on the end of the connecting plate 8 away from the barrel 5.

[0043] In order to achieve ventilation, small holes can be opened on the box body 1. In this embodiment, Figure 1-3 As shown, small holes are provided on the movable cover plate 6 and the connecting plate 8. In some other embodiments, a vent hole can be provided at the bottom of the box body 1, or the bottom of the box body 1 can be hollowed out to facilitate cleaning of residues in the box body 1.

[0044] When the lower part of the box body 1 is hollowed out, a sponge layer is provided at the inner bottom of the box body 1, and a water tray is provided below the box body 1. According to actual use requirements, water can be added to the inner cavity of the box body 1 through the water tray to ensure the humidity of the inner cavity and prolong the freshness of fresh crop leaves. The height of the added water is lower than the upper surface of the sponge layer.

[0045] like Figure 1-2As shown, the box body 1 is provided with a collection channel 11 connected to the inner cavity. The longitudinal section of the collection channel 11 is rectangular. The diameter of the collection channel 11 gradually decreases from one end close to the inner cavity to the other end. A baffle 13 is provided in the collection channel 11 for cutting off the collection channel 11. When aphids need to be collected, the baffle 13 is opened. Figure 1-3 As shown, one end of the collecting channel 11 away from the inner cavity is connected to a collecting box 12 , and an aphid collecting assembly is provided in the collecting box 12 .

[0046] like Figure 5 As shown, the collecting box 12 has a longitudinally extending collecting chamber 14, which is rectangular. The end of the collecting channel 11 away from the inner cavity is connected to the upper part of the collecting chamber 14, and the lower side of the collecting chamber 14 is provided with an opening connected to the collecting chamber 14. The aphid collecting assembly is inserted into the collecting chamber 14 through the opening.

[0047] like Figure 6 As shown, the aphid collection assembly includes a transfer box 15 with an opening on the upper part and a sliding cover 16 slidably arranged at the opening of the transfer box 15. The transfer box 15 is rectangular. When the transfer box 15 is inserted into the collection chamber 14 through the opening, the upper part of the collection chamber 14 is connected to the opening of the transfer box 15, and the four inner walls of the transfer box 15 correspond one-to-one with the four inner walls of the collection chamber 14 and are coplanar.

[0048] The transfer box 15 is slidably matched with the opening. When the transfer box 15 is inserted into place through the opening, Figure 4 Shown, transfer box 15 blocks opening completely, and the aphids that are now positioned in collecting box 12 can not escape from opening. In order to facilitate the movement of transfer box 15, a handle is provided at the outer end of transfer box 15.

[0049] like Figure 6 As shown, in order to facilitate the movement of the sliding cover plate 16, guide grooves are respectively provided on both sides of the transfer box 15. The two guide grooves are arranged opposite to each other, and the sliding cover plate 16 is slidably provided in the two guide grooves.

[0050] like Figure 5 As shown, a light emitting diode 17 is provided in the collecting box 12. When aphids need to be collected, the baffle 13 and the light emitting diode 17 are opened, and the aphids are attracted to the transfer box 15 by their phototaxis. When the transfer box 15 is taken out from the opening, the sliding cover 16 covers the opening.

[0051] Specifically, the transfer box 15 is made of a transparent material, such as Figure 5 As shown, a photogenic light 17 is disposed below the transfer box 15, and a reflector 18 is disposed above the collection chamber 14 for reflecting the light from the photogenic light 17 into the inner cavity of the housing 1. Aphids are first attracted by the light reflected by the reflector 18. When the aphids reach the upper portion of the collection chamber 14, they are then attracted by the light from the photogenic light 17 located below, which facilitates the aphids' entry into the transfer box 15.

[0052] like Figure 5 As shown, the top of the collection box 12 is provided with a spherical rotating cavity, in which a rotating ball 19 rotates. The outer diameter of the rotating ball 19 is greater than the thickness of the top plate of the collection box 12. The rotating cavity is set through the top plate of the collection box 12. The rotating ball 19 can rotate in the rotating cavity but cannot escape from the rotating cavity. The reflector 18 is connected to the lower part of the rotating ball 19 by a connecting rod. The rotating ball 19 is provided with an operating lever 20. When the operating lever 20 is rotated, the rotating ball 19 can be driven to rotate, thereby driving the reflector 18 to rotate, so that the reflected light can illuminate every corner of the inner cavity of the box body 1, or only illuminate a specified location as needed, thereby facilitating the collection of aphids at the specified location.

[0053] To increase friction, Figure 5 As shown, the rotating ball 19 is wrapped with a rubber layer 21. When the rotating ball 19 is rotated to a specified position, the rotating ball 19 can be kept in the current state by friction.

[0054] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
