Abstract
Description
Technical Field
[0001] This utility model relates to an insect testing and observation device suitable for use in cigar drying rooms. Background Technology
[0002] Cigar tobacco is a typical type of air-cured tobacco. After ripening in the field, the tobacco leaves are woven into stalks and placed in drying rooms. Through ventilation and dehumidification in the drying rooms, the tobacco leaves are dried and shaped to form dried cigar tobacco leaves.
[0003] However, during the drying process of cigar tobacco leaves in drying rooms, some storage pests (such as tobacco beetles) can damage the harvested leaves, necessitating research on their control. Storage pests all have corresponding natural enemies (i.e., predatory insects). Using natural enemies to prey on storage pests is a feasible and effective pest control method. However, in practice, the predation of storage pests by predatory insects needs to be studied and observed through prior experiments. Therefore, it is necessary to provide a device that allows workers to easily observe the predation of storage pests by predatory insects, hence this invention. Utility Model Content
[0004] The purpose of this invention is to provide an insect experiment and observation device suitable for use in cigar drying rooms. It is reasonably designed and convenient for staff to observe predation.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is: an insect experimental observation device suitable for use in a cigar drying room, including a drying rod horizontally installed in the drying room, on which multiple cigar tobacco leaves are arranged horizontally, and also including several observation nets spaced horizontally, each observation net covering the outside of several cigar tobacco leaves, the upper end of the observation net being detachably connected to the drying rod, and the inside of the observation net forming an experimental observation space.
[0006] Furthermore, the upper end of the observation net is provided with a pair of covering edges to facilitate wrapping around the outside of the tobacco drying rod from the front and back directions, and the top of the pair of covering edges is detachably connected by a first zipper arranged horizontally.
[0007] Furthermore, an arc-shaped sealing strip is provided on the inner side of the left and right ends of each covering edge. The arc openings of the sealing strips on the left end of the pair of covering edges are set facing each other, and the arc openings of the sealing strips on the right end of the pair of covering edges are set facing each other. The sealing strips on the left and right ends of the pair of covering edges are used to cover the outer periphery of the tobacco drying rod.
[0008] Furthermore, the cross-section of the cigarette drying rod is circular; the sealing strip is semi-circular, and when the tops of a pair of covering edges are connected together by a first zipper, the sealing strips at the left ends of the pair of covering edges and the sealing strips at the right ends of the pair of covering edges form a circle and fit against the outer circumference of the cigarette drying rod.
[0009] Furthermore, the bottom of the observation net is open, and a collection net is provided below the observation net. The upper end of the collection net is detachably connected to the bottom opening of the observation net by a ring chain.
[0010] Furthermore, cameras are installed on the upper left and right inner walls of the observation net.
[0011] Furthermore, the bottom of the tobacco drying rod is provided with several lighting components that are distributed horizontally at intervals. Each lighting component corresponds to the position of an observation net and is located inside the observation net.
[0012] Furthermore, the upper side of the observation net is connected to a first insect inlet tube to facilitate the placement of stored pests into the observation net; the lower side of the observation net is connected to a second insect inlet tube to facilitate the placement of predatory insects into the observation net.
[0013] Furthermore, both the first and second insect inlet tubes are inclined upwards.
[0014] Furthermore, both the first and second insect inlet tubes are flexible tubes, and each is equipped with a tube clamp.
[0015] Compared with the prior art, the present invention has the following advantages: The present invention has a simple and reasonable structural design. The observation net is directly placed on the outside of the tobacco drying rod in the drying room. The environmental conditions inside the observation net are the same as those inside the drying room, which makes it convenient to conduct experiments and observations directly in the drying room without the need to simulate the environmental conditions inside the drying room. The operation is convenient and reduces costs. At the same time, staff can directly observe the predation of storage pests by insects through the observation net. It is convenient and quick to use.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0022] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0023] like Figures 1-5 As shown, this utility model discloses an insect observation device suitable for use in cigar drying rooms. It includes a drying rod 1 horizontally positioned within the drying room, on which multiple cigar tobacco leaves 2 are hung horizontally. The device also includes several observation nets 3 spaced horizontally, each covering the outer side of several cigar tobacco leaves 2. The upper end of the observation nets 3 is detachably connected to the drying rod 1. An observation space 4 is formed inside the observation nets 3, where cigar tobacco leaves, storage pests, and predatory insects are placed. Workers can directly observe the predation of storage pests by predatory insects through the observation nets. This device has a simple and reasonable structural design. By directly covering the drying rod with the observation nets, the environmental conditions inside the nets are identical to those inside the drying room, facilitating direct observation within the drying room without the need for additional simulation of the drying room's environmental conditions. This design is convenient and reduces costs.
[0024] In this embodiment, the upper end of the observation net cover 3 is provided with a pair of front and rear covering edges 5. The pair of covering edges 5 are designed to cover the outside of the tobacco drying rod 1 from the front and rear directions. The top of the pair of covering edges 5 is detachably connected by a horizontally arranged first zipper 6. In use, the pair of covering edges are distributed on the front and rear sides of the tobacco drying rod, and then the upper ends of the covering edges are wrapped around the top of the tobacco drying rod. The tops of the pair of covering edges are connected together by the first zipper, thus allowing the entire observation net cover to be hung on the tobacco drying rod. The observation net cover can be installed and removed by tightening or loosening the first zipper, achieving a detachable connection between the two, which is convenient to operate.
[0025] In this embodiment, an arc-shaped sealing strip 7 is provided on the inner side of the left and right ends of each covering edge 5. The arc openings of the sealing strips 7 on the left end of the pair of covering edges 5 are arranged facing each other, and the arc openings of the sealing strips 7 on the right end of the pair of covering edges 5 are arranged facing each other. The sealing strips 7 on the left end and the sealing strips 7 on the right end of the pair of covering edges 5 are used to cover the outer periphery of the tobacco drying rod 1 so as to play a sealing role at both ends and prevent storage pests or predatory insects from escaping from the gap between the covering edge and the tobacco drying rod.
[0026] In this embodiment, the cross-section of the cigarette drying rod 1 is circular; the sealing strip 7 is semi-circular. When the tops of a pair of covering edges 5 are connected together by the first zipper 6, the sealing strips 7 at the left end of the pair of covering edges 5 and the sealing strips 7 at the right end of the pair of covering edges 5 form a circle and fit against the outer circumference of the cigarette drying rod 1 to improve the sealing effect.
[0027] In this embodiment, the bottom of the observation net 3 is open, and a collection net 8 is provided below the observation net 3. The upper end of the collection net 8 is detachably connected to the bottom opening of the observation net 3 by a ring chain 9. By setting the collection net below the observation net, when predatory insects prey on storage pests, the predatory insects do not completely consume the storage pests (usually selectively consuming certain parts), and the remaining parts of the preyed storage pests fall into the collection net. After a period of experimental observation, the staff removes the collection net and counts the storage pests inside, which helps the staff understand the predation situation (such as how long it took to finish preying on them). It should be noted that after a period of experimental observation, the cigar tobacco leaves can be gently shaken manually to allow any remaining storage pest remains on the tobacco leaves to fall off.
[0028] In another embodiment, cameras 10 are installed on the upper left and right inner walls of the observation net 3. The cameras record the inside of the observation net to capture the predation situation.
[0029] In another embodiment, to facilitate viewing by staff, the bottom of the tobacco drying rod 1 is provided with several lighting components distributed horizontally at intervals. Each lighting component corresponds to the position of an observation net 3 and is located inside the observation net 3. The lighting components increase the brightness inside the observation net 3. Preferably, the lighting components are a pair of LED lights 11 distributed from left to right, and the pair of LED lights are installed at the bottom of the tobacco drying rod.
[0030] In this embodiment, the upper side of the observation net 3 is connected to a first insect inlet tube 12, which facilitates the insertion of stored pests into the observation net 3.
[0031] In this embodiment, a second insect inlet tube 13 is connected to the lower side of the observation net 3, which facilitates the insertion of predatory insects into the observation net 3.
[0032] In this embodiment, both the first insect inlet tube 12 and the second insect inlet tube 13 are inclined upwards.
[0033] In this embodiment, both the first insect inlet tube 12 and the second insect inlet tube 13 are flexible tubes, and both the first insect inlet tube and the second insect inlet tube are equipped with tube clamps 14 to clamp the insect inlet tubes and prevent stored pests and predatory insects from escaping.
[0034] In this embodiment, both the observation mesh and the collection mesh can be transparent mesh.
[0035] In this embodiment, three observation nets are arranged side by side. Each observation net can be set with different numbers of stored pests, predatory insects, and experimental observation time as needed, so as to form an experimental control.
[0036] In another embodiment, a horizontally arranged screen 15 is fixed at the lower end of the inner side of the observation screen 3, which can prevent tobacco fragments from falling into the collection screen to a certain extent.
[0037] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then, unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).
[0038] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.
[0039] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.
[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
