Description

TECHNICAL FIELD

[0001] The present application relates to the field of pest trapping, in particular to an efficient physical trapping device for pests of fruit trees. BACKGROUND

[0002] During the process of planting fruit trees, pest control is a key link to protect the yield and quality of fruits. Physical trapping is widely used due to its environmental protection and no pesticide residue. After installing the trapping device on the fruit tree, the pests of the fruit tree can be targeted for trapping and killing by releasing trapping odor to simulate the suitable living environment of pests, setting up ultraviolet lamps to utilize the phototaxis of pests, or using insecticidal liquid, etc., so as to effectively reduce the damage of pests to the leaves and fruits of the fruit trees.

[0003] In the prior art, a patent with publication number CN215531040U discloses a device for trapping and killing overwintering pests of forest fruit trees. The device is fixed on the trunk by an inner lining layer, and a corrugated pest trapping core is used to form a maze-like space to provide a suitable place for overwintering pests. An anti-escape outer layer is used to form a closed environment to achieve the trapping of overwintering pests. Finally, the pests are killed by high-temperature baking or water soaking through a recycling device. However, although this technology improves some of the original problems, there are still aspects that need to be further optimized to better meet the actual pest killing needs.

[0004] The above-mentioned device uses a corrugated structure as the trapping core, and the core is to build an overwintering space for pests and prevent escape through the structure gap. However, the practical application is significantly limited. From the perspective of cleaning, the triangular cavities and fine gaps of the corrugated trapping core can accommodate pests, but they are easy to get stuck in them. If the pests that enter earlier are large in size, they will be stuck in the upper end of the corrugated structure, causing blockage and preventing subsequent pests from entering, which greatly reduces the trapping efficiency.

[0005] In addition, the device is hung on the trunk in the open air, and the corrugated gap and the horn structure of the anti-escape outer layer are easy to be blocked by fallen leaves and branches blown by the wind, further hindering the entry of pests and increasing the difficulty of cleaning the device. Functionally, it only targets overwintering pests and has no real-time killing function, and it needs to rely on manual processing later, which is difficult to deal with the problem of early activity or escape of pests, and has no control effect on pests during non-overwintering period. The function is single and cannot meet the needs of the whole growth cycle of fruit trees, and the applicability is limited.

[0006] Therefore, under the above-mentioned points, there is still room for improvement in the existing pest killing device. SUMMARY

[0007] In order to solve the above problems, the present application provides a kind of high-efficiency physical trapping device for fruit tree pests, including two symmetrically distributed and section L-shaped outer tubes, the inner diameter of outer tube is also installed with inner tube, the outer side of outer tube is symmetrically installed with extension plate, and fixed bolt is threadedly passed between the corresponding extension plates of front and back.

[0008] The space between the two outer tubes and the inner tube is a falling cavity.

[0009] A plurality of bending plates are installed between the outer tube and the inner tube, and a light assembly for attracting pests by light is installed on the inner tube.

[0010] A receiving assembly for receiving pests in the falling cavity is installed on the inner bottom wall of the outer tube.

[0011] The bottom of the outer tube on one side is installed with a fixing assembly for fixing it outside the fruit tree.

[0012] Preferably, the light assembly includes an arc-shaped slot opened at the top of the inner tube, and an arc-shaped lamp plate is installed in the arc-shaped slot.

[0013] The top of the inner tube is chamfered, and the chamfer is inclined towards the outer tube.

[0014] Preferably, an electric shock device is also installed on the outer side of the inner tube, and a plurality of electric shock strips extending into the falling cavity are installed on the outer side of the electric shock device.

[0015] Preferably, the receiving assembly includes an arc-shaped placement slot opened at the bottom of the outer tube, and a receiving box is slidably inserted into the placement slot, and the top of the receiving box is open and corresponds to the falling cavity.

[0016] A plurality of rubber strips are uniformly distributed along the outer side of the receiving box, and the rubber strips abut against the inner side wall of the placement slot.

[0017] Preferably, a pulling shaft is also installed on the inner bottom wall of the receiving box, and a pulling plate is fixedly sleeved on the outer side of the bottom of the pulling shaft.

[0018] Preferably, two filling plates corresponding to the receiving boxes at both ends are symmetrically installed on the inner bottom wall of the outer tube, and the top of the filling plate is chamfered and inclined towards the corresponding receiving box.

[0019] Preferably, the fixing assembly includes an L-shaped plate symmetrically installed at the bottom of the outer tube on one side, a threaded column is threadedly passed through the middle of the L-shaped plate, and the axis of the threaded column corresponds to the axis of the falling cavity.

[0020] An arc-shaped plate is rotatably installed at the end of the threaded column.

[0021] A rotating plate is fixedly sleeved on the outer side of the threaded column.

[0022] The inner diameter of the arc-shaped plate is provided with a rubber pad.

[0023] The inner diameter of the inner cylinder is provided with an arc-shaped rubber plate, and the upper end of the arc-shaped rubber plate is chamfered and inclined towards the falling cavity.

[0024] In summary, the present application has at least one of the following beneficial technical effects: First, the present application significantly improves the trapping and killing efficiency and stability by using the triple mode of light attraction, electric shock killing and liquid immersion killing, combined with the blocking design of the bent plate. The arc-shaped light plate precisely attracts target pests using their phototaxis, and the gap between the bent plates provides a dedicated channel for pests while effectively blocking fallen leaves, branches and other debris from entering the falling cavity and causing channel blockage. Pests that enter the cavity can be directly killed or paralyzed by the electric current released by the electric shock strip, or those that do not trigger the electric shock will fall into the box under the attraction of the liquid smell in the receiving box and be immersed and killed, solving the problem of limited effect of single trapping method and ensuring effective treatment of pests in different activity states.

[0025] Second, the present application greatly reduces the cost of manual maintenance and avoids trapping failure through the design of a detachable receiving assembly and an anti-clogging structure. The sliding connection of the receiving box and the outer cylinder, combined with the limiting action of the rubber strip, allows the operator to easily pull out the receiving box by pulling the board, achieving quick operation of pest carcass cleaning and liquid replacement. The inclined chamfer design of the inner cylinder reduces pest accumulation, and the inclined structure of the filling plate guides the escaped pests into the receiving box, avoiding clogging caused by pests or carcasses stuck in the device gap. Compared to the traditional corrugated structure which needs to be frequently disassembled and cleaned, the present device significantly reduces the maintenance frequency and the working intensity of the operator.

DETAILED DESCRIPTION

[0033] The following Figures 1 to 5 The embodiments of the present application are described in detail.

[0035] Referring to Figures 1 to 5 As shown in the figure, including outer cylinder 1, inner cylinder 10, extension plate 11, fixing bolt 12, falling cavity 13, bending plate 14, light assembly 2, receiving assembly 3 and fixing assembly 4, two cross sections L-shaped outer cylinder 1 is symmetrically distributed, the inner diameter of outer cylinder 1 is also provided with inner cylinder 10, the outer side of outer cylinder 1 is symmetrically provided with extension plate 11, the corresponding extension plate 11 between front and back is commonly provided with fixing bolt 12, that is, two extension plates 11 can be fixed by fixing bolt 12, and two groups of outer cylinder 1 and inner cylinder 10 are fixed to form a ring-shaped cylinder structure, when the device is disassembled from the tree, the fixing bolt 12 is disassembled from the extension plate 11, and the two groups of outer cylinder 1 and inner cylinder 10 can be disassembled from the tree, and vice versa when installing, the outer side of the two groups of outer cylinder 1 and inner cylinder 10 is fixed to the tree by fixing bolt 12, so that the space between the two outer cylinders 1 and inner cylinders 10 forms a falling cavity 13.

[0036] A plurality of bending plates 14 are installed between the outer cylinder 1 and the inner cylinder 10, and the inner cylinder 10 is provided with a light assembly 2 for attracting pests by light, the pests can enter the falling cavity 13 through the gap between the bending plates 14, and the bending plates 14 are used to block large falling objects such as branches and leaves, to prevent them from falling into the falling cavity 13 through the gap between the bending plates 14.

[0037] The inner bottom wall of the outer cylinder 1 is provided with a receiving assembly 3 for receiving pests in the falling cavity 13; The bottom of the outer cylinder 1 on one side is provided with a fixing assembly 4 for fixing it on the outer side of the fruit tree.

[0038] Referring to Figures 1 to 3 As shown in the figure, the light assembly 2 is used to attract pests by light irradiation; specifically, the light assembly 2 comprises an arc-shaped light plate 20, an electric shock device 21 and an electric shock strip 22, and the top of the inner cylinder 10 is provided with an arc-shaped groove, and the arc-shaped light plate 20 is installed in the arc-shaped groove.

[0039] The top of the inner cylinder 10 is chamfered, and the chamfer is inclined towards the outer cylinder 1, so as to avoid excessive stay of insects on the top of the inner cylinder 10.

[0040] The electric shock device 21 is further installed on the outer side of the inner cylinder 10, and a plurality of electric shock strips 22 extending into the falling cavity 13 are installed on the outer side of the electric shock device 21.

[0041] The arc-shaped light plate 20 emits light at night to attract pests, and the pests enter the falling cavity 13 through the gap of the bending plate 14 after being attracted by light, part of the pests will touch the electric shock strip 22 of the electric shock device 21, and the electric shock strip 22 releases current to kill or temporarily paralyze the pests, so that the pests fall into the receiving assembly 3 below; the electric shock device 21 selects the existing mature electric shock equipment to ensure the stability of the killing. The implementer can flexibly replace the suitable electric shock equipment according to the actual needs of the type of fruit tree pests, garden environment, etc., as long as the core function of stable killing of pests is met, and the specific equipment model is not limited in the embodiment.

[0042] Referring to Figures 2 to 3 As shown in the figure, the receiving assembly 3 is used to receive the pests in the falling cavity 13; specifically, the receiving assembly 3 comprises a receiving box 30, a rubber strip 31, a pulling shaft 32, a pulling plate 33 and a filling plate 34, the bottom of the outer cylinder 1 is provided with a placing groove in the shape of an arc, the receiving box 30 is slidingly inserted into the placing groove, and the top of the receiving box 30 is open and corresponds to the falling cavity 13.

[0043] Considering that only part of the pests will touch the electric shock strip 22 below after being attracted by the arc-shaped light plate 20, and part of the pests cannot be completely killed by electric shock, the implementer can pour pesticide into the receiving box 30. The smell of the pesticide will make the pests entering the falling cavity 13 move towards the receiving box 30, and if the pests touch the electric shock strip 22 during the moving process, they will be killed or paralyzed and fall down. Even if the pests are not killed by electric shock, they will also be immersed and killed by the pesticide after falling into the receiving box 30.

[0044] In summary, the present application has the synergistic effect of light attraction, electric shock killing and paralysis, and drug attraction and immersion, which not only makes up for the defect that single electric shock method cannot completely kill pests, but also solves the problem of easy dispersion of the smell of the pesticide and the decay of the killing effect, and perfects the whole process of pest trapping.

[0045] The outer side of the receiving box 30 is provided with a plurality of rubber strips 31 uniformly distributed along the outer side surface, and the rubber strips 31 abut against the inner side wall of the placing groove. The inner bottom wall of the receiving box 30 is further provided with a pulling shaft 32, and a pulling plate 33 is fixedly sleeved on the outer side of the bottom of the pulling shaft 32.

[0046] The rubber strips 31 increase the friction between the receiving box 30 and the inner wall of the placing groove, thereby preventing the receiving box 30 from falling out of the placing groove. When it is necessary to clean the insect corpses in the receiving box 30 and replace the pesticide, the implementer can pull the pulling plate 33 to pull out the receiving box 30 from the placing groove through the pulling plate 33 and the pulling shaft 32. The length of the pulling shaft 32 can be flexibly replaced and adapted according to the installation height of the device on the fruit tree. After the insect corpses and the old pesticide are poured out, the receiving box 30 is cleaned and filled with new pesticide, the receiving box 30 is pushed back into the placing groove through the pulling plate 33, and the receiving box 30 is repositioned by the friction of the rubber strips 31.

[0047] The inner bottom wall of the outer cylinder 1 is further provided with two filling plates 34 symmetrically installed at the positions corresponding to the two ends of the receiving box 30, and the top of the filling plate 34 is inclined to the corresponding receiving box 30.

[0048] The filling plate 34 is used to fill the gap between the two receiving boxes 30 to prevent insects from falling into the gap. Insects can slide along the inclined chamfer to the receiving box 30 on one side.

[0049] Referring to Figure 4 and Figure 5 , that is, a fixing assembly 4 for fixing the device outside the fruit tree. Specifically, the fixing assembly 4 includes an L-shaped plate 40, a threaded column 41, an arc-shaped plate 42, a rotating plate 43, a rubber pad 44, and an arc-shaped rubber plate 45. Two L-shaped plates 40 are symmetrically installed at the bottom of one side of the outer cylinder 1, and a threaded column 41 is threadedly penetrated in the middle of the L-shaped plate 40. The axis of the threaded column 41 corresponds to the axis of the falling cavity 13. An arc-shaped plate 42 is rotatably installed at the end of the threaded column 41. A rotating plate 43 is fixedly sleeved on the outer side of the threaded column 41.

[0050] The rubber pad 44 is installed on the inner diameter of the arc-shaped plate 42, and the arc-shaped rubber plate 45 is installed on the inner diameter of the inner cylinder 10. The upper end of the arc-shaped rubber plate 45 is inclined to the falling cavity 13.

[0051] When the device is fixed outside the fruit tree, the implementer can rotate the rotating plate 43 to drive the threaded column 41 to rotate in or out along the threaded hole of the L-shaped plate, thereby pushing the arc-shaped plate 42 to move towards the fruit tree. Since the arc-shaped plate 42 is rotatably connected with the threaded column 41, when the threaded column 41 drives the arc-shaped plate 42 to move a distance, the arc-shaped plate 42 will first contact the outside of the fruit tree and then automatically return to the normal position, and then move smoothly in the direction towards the fruit tree.

[0052] After the rubber patch 44 on the arc-shaped plate 42 is closely attached to the surface of the fruit tree, the threaded column 41 is stopped, at which time the arc-shaped plate 42 and the arc-shaped rubber plate 45 on the inner side of the inner cylinder 10 cooperate with each other to clamp and fix the fruit tree from the inside and outside. Among them, the rubber patch 44 and the arc-shaped rubber plate 45 can increase the friction between the device and the fruit tree, avoiding the device from sliding and deviating, and at the same time, the structure design of the arc-shaped rubber plate 45 tilting towards the side of the fruit tree can fully fill the gap between the inner cylinder 10 and the fruit tree, effectively preventing pests from hiding in the gap.

[0053] When working: first, the implementer combines the two groups of outer cylinders 1 and inner cylinders 10 into a ring-shaped cylinder structure through the fixed bolts 12 and extension plates 11, and puts the device on the outside of the fruit tree trunk, ensuring that the falling cavity 13 forms a closed trapping space with the trunk.

[0054] Second, rotate the threaded column 41 of the fixed assembly 4 to push the arc-shaped plate 42 and the arc-shaped rubber plate 45 to clamp the trunk from the inside and outside, increase the friction through the rubber patch 44 and the arc-shaped rubber plate 45 to prevent the device from sliding, and at the same time, the inclined structure of the arc-shaped rubber plate 45 fills the gap to block the hiding of pests.

[0055] Third, turn on the arc-shaped light plate 20 of the light assembly 2 at night, use the phototaxis of pests to attract them to pass through the gap of the bent plate 14 into the falling cavity 13, and the bent plate 14 blocks branches and fallen leaves to avoid blocking the passage.

[0056] Fourth, when the pests move in the falling cavity 13, part of them touch the electric shock strip 22 and are killed or paralyzed by electric current, and the rest are induced to move to the box body by the smell of the liquid in the receiving box 30, and may trigger the electric shock strip 22 again on the way.

[0057] Fifth, regularly pull out the receiving box 30 through the pull-out plate 33 to clean up the pest corpses and replace the liquid, use the friction between the rubber strip 31 and the placement groove to fix the box body, and at the same time, the filling plate 34 tilts and chamfers to guide the pests that slip through the net into the receiving box 30.

[0058] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

[0059] In addition, it should be understood that although the present specification is described in terms of embodiments, each embodiment does not contain only one independent technical solution, and the description manner of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that those skilled in the art can understand.
