Description

Technical Field

[0001] The invention relates to the field of biological control of pests, and in particular to a pest pathogenic bacteria releasing device. Background Art

[0002] In the control of stored-grain pests, the long-term and irrational use of phosphine and protective agents has led to the widespread development of pest resistance. The widespread occurrence of resistance has reduced the control effect of traditional agents.

[0003] Pathogens such as Beauveria bassiana and Metarhizium anisopliae have insecticidal activity against a variety of stored-grain pests. They have the characteristics of good persistence and thorough insecticide control, and there is no problem of pesticide residues. They have broad application prospects in the prevention and control of stored-grain pests.

[0004] However, pathogens have their own characteristics, which also limit their use in granaries. For example, the grain storage environment in granaries is relatively dry, and pathogens can only survive in a high humidity environment. The dry grain storage environment is not suitable for the survival of pathogens and is not conducive to the release of pathogens to infect pests. Therefore, in order to ensure the survival and proliferation ability of pathogens in the granary environment and increase the probability of pests infecting pathogens, it is necessary to provide a high humidity environment for pathogens. The long-term existence of a high humidity environment may cause mildew problems in grain. How to ensure the survival of pathogens while not creating a long-term high humidity environment in the granary has become a difficult problem for the promotion and use of pathogens in granaries. Summary of the invention

[0005] The object of the present invention is to provide a pathogen releasing device which is suitable for pathogen cultivation and will not cause excessive local humidity in a warehouse.

[0006] In order to solve the above technical problems, the technical solution of a pest pathogen release device in the present invention is as follows:

[0007] A pest pathogen release device comprises a device base, on which a humidity control mechanism and an infection mechanism arranged on the left and right are arranged, the infection mechanism comprises an infection space having an infection space insect inlet and an infection space insect outlet, a plurality of vertically arranged infection cloth strips are arranged in the infection space between the infection space insect inlet and the infection space insect outlet, a first sponge block is arranged at the bottom of the infection space, the lower end of each infection cloth strip is connected to the first sponge block, the humidity control mechanism comprises a storage chamber for storing pathogen liquid and a reversing pulley with a rotation axis extending in a front-to-back direction, a power transmission member with a left end extending into the storage chamber is wound around the reversing pulley, the right end of the power transmission member is located on the right side of the storage chamber, a second sponge block is arranged on the left side of the first sponge block, the right end of the power transmission member is connected to the second sponge block, a liquid outlet is arranged at the bottom of the storage chamber, the liquid outlet is connected to the second sponge block through a hose, and the left end of the power transmission member is connected to a valve core for moving upward to block the liquid outlet and moving downward to conduct the liquid outlet with the storage chamber.

[0008] Furthermore, a counterweight block is connected in series on the upper side of the valve core on the power transmission component, and the power transmission component includes a flexible rope segment connected between the counterweight block and the second sponge block and a rigid rod segment connected between the counterweight block and the valve core. The counterweight block is located above the liquid level of the pathogen liquid in the storage chamber.

[0009] Furthermore, a valve core guide hole is provided at the bottom of the storage chamber, and a liquid outlet is opened on the side wall of the valve core guide hole. The valve core includes a bottom sealing section for sealing the liquid outlet. A liquid guide groove extending in the up-and-down direction is opened on the upper outer peripheral surface of the bottom sealing section on the valve core. When the valve core moves downward, the liquid guide groove is used to realize the connection between the liquid outlet and the storage chamber.

[0010] Furthermore, a vertically arranged flying pest guide channel is provided on the right side of the infection space, the insect entrance of the infection space is provided on the upper right wall of the flying pest guide channel, a channel insect exit is provided on the lower left wall of the flying pest guide channel, and the insect exit of the infection space is provided on the left side of the infection space.

[0011] Furthermore, the insect exit of the infection space is located at the lower left end of the infection space.

[0012] Furthermore, the infected cloth strips include a plurality of concentrically arranged infected cloth strip circles, each infected cloth strip circle includes a plurality of infected cloth strips spaced apart along the circumferential direction, and in the radial direction, among two adjacent infected cloth strip circles, the infected cloth strips of one infected cloth strip circle are staggered with the infected cloth strips of the other infected cloth strip circle.

[0013] Furthermore, a sponge guide hole is provided on the left side of the first sponge block, a sponge bottom plate is provided on the lower side of the second sponge block, a left sponge baffle is provided on the left side of the second sponge block, a sponge top plate is provided on the upper side of the second sponge block, and vertically arranged transmission member throughholes for the power transmission member to pass through are provided on the sponge top plate and the second sponge block. The power transmission member is connected to the second sponge block by being connected to the sponge bottom plate, and the right side of the second sponge block is used to connect to the first sponge block to introduce pathogenic bacteria liquid into the first sponge block.

[0014] Furthermore, a top plate limiting structure is provided on the upper side of the sponge guide hole for cooperating with the upper end stop of the sponge top plate to limit the upward movement limit of the sponge top plate.

[0015] Furthermore, a valve core limiting structure is provided at the bottom of the storage cavity on the upper side of the valve core for cooperating with the upper end stop of the valve core to limit the upward movement limit of the valve core.

[0016] The beneficial effects of the present invention are as follows: in the present invention, when there is less pathogenic bacteria liquid in the second sponge block, the second sponge block is lighter as a whole, and the valve core is in a low position. At this time, the liquid outlet supplies pathogenic bacteria liquid into the second sponge block through a hose. As the pathogenic bacteria liquid in the second sponge block increases, the weight of the second sponge block gradually increases, the valve core moves upward and gradually blocks the liquid outlet, the second sponge block moves downward and contacts the first sponge block, and the second sponge block supplies pathogenic bacteria liquid to the first sponge block, so that each infected cloth strip connected to the first sponge block also absorbs the pathogenic bacteria liquid, and flying pests enter the infection space through the insect inlet of the infection space. In the infection space, the flying pests contact the infected cloth strips and are infected with pathogens. After the flying pests fly out through the insect outlet of the infection space, they infect other flying pests, thereby realizing biological control of pests. In the present invention, during the process of the second sponge block supplying pathogen liquid to the first sponge block, the liquid outlet is blocked, so the problem of excessive local humidity caused by the second sponge block's humidity continuously increasing and causing excessive humidity in the first sponge block and the infected cloth strip will not occur. The liquid storage cavity, the first sponge block, the second sponge block and the infected cloth strip all provide conditions for the cultivation of pathogens. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] In order to facilitate the understanding of the present invention, the present invention is described in more detail below in conjunction with the accompanying drawings and specific embodiments. Preferred embodiments of the present invention are provided in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described in this specification. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0025] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] An embodiment of a pest pathogen releasing device of the present invention is as follows: Figures 1 to 5As shown: it includes a device base 4, and a humidity control mechanism 1 and an infection mechanism 15 arranged on the left and right are arranged on the upper end of the device base 4. The infection mechanism 15 includes an infection space 27 with an infection space insect inlet 16 and an infection space insect outlet 13, the upper end of which is blocked by a sealing plate. A plurality of vertically arranged infection cloth strips 14 are arranged in the infection space between the infection space insect inlet 16 and the infection space insect outlet 13. The upper end of the infection cloth strip 14 in this embodiment is connected to the sealing plate. The arrangement form of the infection cloth strip is: the infection cloth strip includes a plurality of concentrically arranged infection cloth strip circles, each infection cloth strip circle includes a plurality of the infection cloth strips arranged at intervals along the circumferential direction, and in the radial direction, in two adjacent infection cloth strip circles, the infection cloth strips of one infection cloth strip circle are staggered with the infection cloth strips of the other infection cloth strip circle.

[0027] A vertically arranged flying pest guide channel 17 is arranged on the right side of the infection space, an infection space insect entrance 16 is arranged on the upper right wall of the flying pest guide channel, a channel insect exit 18 is opened on the lower left wall of the flying pest guide channel, and an infection space insect exit 13 is arranged on the left side of the infection space. The infection space insect exit is opened at the bottom of the left wall of the infection space.

[0028] A first sponge block 12 is provided at the bottom of the infection space, and the lower end of each infected cloth strip 14 is connected to the first sponge block 12. When there is pathogen liquid in the first sponge block 12, the pathogen liquid will flow from bottom to top along the infected cloth strip, so that the infected cloth strip contains pathogen liquid.

[0029] The humidity control mechanism includes a storage chamber 3 for storing pathogen liquid and a reversing pulley 6 whose rotation axis extends in the front-to-back direction. A power transmission member 7 is wound around the reversing pulley 6, and the left end of the power transmission member extends into the storage chamber. The right end of the power transmission member is located on the right side outside the storage chamber. A second sponge block 11 is arranged on the left side of the first sponge block 12, and the right end of the power transmission member is connected to the second sponge block. A liquid outlet 19 is arranged at the bottom of the storage chamber, and the liquid outlet 19 is connected to the second sponge block 11 through a hose 10. The left end of the power transmission member is connected to a valve core 9 for moving upward to block the liquid outlet and moving downward to connect the liquid outlet 19 with the storage chamber.

[0030] A counterweight block 5 is connected in series on the upper side of the valve core on the power transmission component. The power transmission component includes a flexible rope segment connected between the counterweight block 5 and the second sponge block 11 and a rigid rod segment 8 connected between the counterweight block 5 and the valve core 9. The counterweight block 5 is located above the liquid level 2 of the pathogen liquid in the storage chamber, so that the counterweight block can be prevented from being affected by the buoyancy of the pathogen liquid. Figure 1 The middle item 2 represents the liquid level of the pathogen solution.

[0031] A valve core guide hole is provided at the bottom of the storage chamber 3, and a liquid outlet 19 is provided on the side wall of the valve core guide hole. The valve core includes a bottom sealing section 20 for blocking the liquid outlet. A liquid guide groove 21 extending in the up-down direction is provided on the upper outer peripheral surface of the bottom sealing section of the valve core 9. When the valve core 9 moves downward, the liquid guide groove 21 is used to connect the liquid outlet 19 and the storage chamber 3. A valve core limiting structure 22 is provided on the upper side of the valve core at the bottom of the storage chamber 3 for cooperating with the upper end stop of the valve core to limit the upward movement limit of the valve core.

[0032] A sponge guide hole is provided on the left side of the first sponge block 12, a sponge bottom plate 24 is provided on the lower side of the second sponge block 11, a left sponge baffle 25 is provided on the left side of the second sponge block, a sponge top plate 26 is provided on the upper side of the second sponge block, and vertically arranged transmission member through-holes for power transmission members to pass through are provided on the sponge top plate 26 and the second sponge block 11. The power transmission member is connected to the second sponge block by being connected to the sponge bottom plate 24, and the right side of the second sponge block is used to connect to the first sponge block to introduce pathogenic bacteria liquid into the first sponge block.

[0033] The upper side of the sponge guide hole is provided with a top plate limiting structure 23 for cooperating with the upper end stop of the sponge top plate to limit the upward movement limit of the sponge top plate.

[0034] When in use, when there is not much pathogenic bacteria liquid in the second sponge block, the weight of the counterweight block is greater than the weight of the second sponge block. Figure 3 As shown, the valve core moves downward to a low position, and the liquid guide groove on the outer periphery of the valve core is connected to the inner cavity of the storage cavity. The pathogen liquid in the storage cavity flows to the second sponge block through the liquid guide groove, the liquid outlet and the hose. The weight of the second sponge block gradually increases. When the weight of the second sponge block is greater than the pulling force of the counterweight block and the valve core below it, the second sponge block moves downward and the valve core moves to a high position, as shown in FIG. Figure 1 As shown, at this time, the bottom sealing section on the valve core blocks the liquid outlet, and the storage chamber no longer supplies pathogen liquid to the second sponge block. The left sponge baffle, the sponge top plate and the sponge bottom plate can limit the flow direction of the pathogen liquid in the second sponge block. The pathogen liquid will flow to the right toward the first sponge block and then flow toward the infected cloth strip. The weight of the sponge top plate can also act on the second sponge block, and by applying pressure to the second sponge block, the flow of the pathogen liquid from the second sponge block to the first sponge block can be accelerated.

[0035] The flying pests enter the infection space through the insect entrance of the infection space and the insect exit of the guide channel, and then fly to the insect exit of the infection space. During the process, the flying pests come into contact with the infected cloth strips and are infected with pathogens. After the flying pests are infected with pathogens, they fly out of the infection space and can infect other pests, thereby realizing biological control of pests.
