Description

Technical Field

[0001] The utility model relates to a trap, in particular to an insect pest control trap for pear trees. Background Art

[0002] As an economic crop, the yield and quality of pears produced by pear trees directly affect the income of fruit farmers. Pear borers, a major pest, eat the tender shoots and fruits of pear trees, causing damage to both the trees and the fruits.

[0003] The existing prevention and control methods mainly include pesticide spraying and trapping. Among them, trapping is becoming more and more popular because it is green and environmentally friendly and does not form pesticide residues.

[0004] It should be noted that existing traps are usually based on ultraviolet light trapping and sexual trapping. That is, after the pear borer is trapped, it is electrocuted or stunned by the electric grid, ultimately achieving the purpose of pest control.

[0005] The existing problem is that the adult pear borer is large in size and easily gets stuck on the electric grid when passing through it, which causes the effective insect-killing part of the electric grid to be occupied by the stuck pear borer. Fruit farmers need to frequently clean the electric grid of the trap, which is very inconvenient.

[0006] In addition, the existing trap is equipped with a collection bag at the bottom. After trapping for a period of time, the fruit farmer needs to clean out the trapped pear borer in the collection bag in time to make room for the pear borer that is subsequently trapped. Utility Model Content

[0007] The purpose of the utility model is to provide a pest control trap for pear trees, so as to improve the problems of existing traps, that is, pests are easily stuck on the electric net, occupying the effective insecticidal part of the electric net, and the collection bag needs to be cleaned regularly.

[0008] To achieve the above objectives, the present invention provides the following technical solutions:

[0009] A pest control trap for pear trees, comprising

[0010] a tray, wherein the tray is funnel-shaped;

[0011] An electric grid insecticide mechanism is provided on the tray to electrocute the lured pests. The electric grid insecticide mechanism includes a coaxial electric grid group provided above the tray. The electric grid group includes an inner electric grid and an outer electric grid, forming an annular channel between the inner electric grid and the outer electric grid. The electric grid group also includes an electric control component electrically connected to the electric grid group.

[0012] The cleaning mechanism includes a motor A coaxially arranged at the upper end of the electric control component. A lever is driven and connected to the output shaft of the motor A and extends axially into the annular channel along the power grid group.

[0013] The trapping mechanism is arranged at the center of the power grid group to send out luring information to the outside.

[0014] The collection bag is arranged at the bottom of the tray to collect the pests that fall into the tray after being electrocuted. The lower end of the collection bag is open.

[0015] The retracting and releasing mechanism is arranged below the tray and is connected to the open end at the lower end of the collection bag to periodically open and tighten the open end at the lower end of the collection bag.

[0016] Preferably, the retracting and releasing mechanism includes at least three support rods connected to the bottom of the tray. The support rods extend downward and outward. The lower end of the support rod is elastically hinged to a pry bar. The inner end of the pry bar is connected to the edge of the lower open end of the collection bag. The outer end of the pry bar is connected to a traction rope. A motor B electrically connected to the electric control component is further arranged on the lower surface of the tray. The traction rope is wound around the output shaft of the motor B so that when the motor B rotates, the inner end of the pry bar can be pulled outward to turn over through the traction rope.

[0017] Preferably, an elastic rubber ring is arranged around the open end at the lower end of the collection bag. The inner end of the pry bar is connected to the elastic rubber ring.

[0022] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0023] 1. In the cleaning mechanism of this solution, the lever moves in the annular channel between the power grid groups to periodically clean the pests stuck on the power grid groups and keep the power grid groups clean. At the same time, the retracting and releasing mechanism below periodically opens the lower open end to periodically pour out the dead pests in the collection bag, ensuring that the collection bag has enough space to collect new captured pests.

[0024] 2. The function of setting the elastic rubber ring is to enable the lower opening of the collection bag to have a tendency to contract and close, ensuring that after emptying the pests in the collection bag, the collection bag can close itself.

[0025] 3. Set bristles to increase the sealing effect of the lower opening of the collection bag.

[0033] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0036] As Figures 1 to 4 shown, a pest control trap for pear trees includes a tray 100, which is funnel-shaped; there is an open channel in the middle for the trapped pests to enter. A power grid pest control mechanism 200 is installed above the tray to kill the attracted pests in the form of electric current. It should be noted that the power grid pest control mechanism in this solution has the same principle as the traditional electric mosquito swatter for pest control but has certain differences in structure. Specifically, the power grid pest control mechanism in this solution includes a power grid group 210 installed above the tray and an electronic control component 220 that provides power for the power grid group. Among them, the power grid component includes an inner power grid 211 connected to the tray in a cylindrical shape and an outer power grid 212 coaxially covering the outside of the inner power grid. There is a gap between the inner power grid and the outer power grid to form an annular channel. When a large voltage difference is applied to the two respectively to form a high-voltage electric field, when the attracted pests enter between the two and conduct them, the current passes through the pests to electrocute the pests. It should be noted that as Figure 1 shown, the gap between the inner power grid and the outer power grid is annular to form an annular channel, ensuring that the pests can be killed by the current generated by the power grid group that can be conducted no matter from which direction they enter between the inner and outer power grids.

[0037] It should be noted that in the above scheme, the electronic control assembly 220, as a mechanism capable of providing power to the internal and external power grids, operates on the same principle as an electric mosquito swatter. Specifically, it comprises a battery for providing power, a high-frequency oscillator circuit for converting the battery's direct current into high-frequency alternating current, and a boost circuit for increasing the voltage of the high-frequency alternating current. The internal and external power grids in the power grid group are connected to the boost circuit, providing continuous power for the group's electrocution of insects.

[0038] It should be noted that, since the pests are electrocuted after entering the electric grid, they lose the power to move forward or backward and are easily stuck on the electric grid, thereby blocking the passage on the electric grid and preventing the subsequent lured pests from entering between the electric grids, thus reducing the killing effect. Therefore, it is necessary to clean up the pests stuck on the electric grid in time, and it is necessary to install a cleaning mechanism 300 on the electric control component 220. Figure 1 As shown, the cleaning mechanism includes a motor A310 coaxial with the power grid. Motor A is fixedly mounted on the upper end of the electronic control assembly 220 and electrically connected to the battery within the assembly. A lever 320 is also connected to the output shaft of battery A. A section of the lever extends horizontally and then vertically along the motor's axis to enter the annular channel formed by the power grid. When the lever rotates under the drive of motor A, pests trapped in the power grid are promptly removed. It should be noted that these removed pests fall from the power grid and onto the tray, ultimately passing through the channel in the center of the tray and into the collection bag 500 mounted below the tray.

[0039] It should be noted that in this solution, to maximize pest attraction, a trapping mechanism 400 is added to the power grid. This trapping mechanism can emit external attracting signals, such as light or sexual signals, to attract the pests. Specifically, the trapping mechanism 400 can include an ultraviolet lamp 410 mounted at the center of the power grid 210 and electrically connected to the battery in the electronic control assembly 220. The ultraviolet lamp preferably has a photoelectric sensor switch, meaning it only operates at night, maximizing energy conservation and enhancing the ultraviolet attracting effect. Furthermore, a sex attractant 420 can be placed beneath the ultraviolet lamp to lure pests closer by distributing sex pheromones into the air. It should be noted that these two approaches work together to achieve all-weather pest attraction.

[0040] When the pests are attracted and electrocuted when passing through the electric wire grid group, they fall into the lower tray 100 and then fall into the collecting bag 500 installed below through the guidance of the tray. It should be noted that in this solution, in order to achieve the timed cleaning of the pest corpses in the collecting bag, the bottom of the collecting bag is provided with an open mouth. At the same time, a retracting mechanism 600 is installed at the bottom of the tray. The retracting mechanism is electrically connected to the battery in the electric control component to achieve the timed opening of the lower open mouth of the collecting bag and the long-term shrinkage closure.

[0041] Specifically, as Figure 1 , Figure 2 shown, the retracting mechanism 600 that can control the open and closed states of the open mouth of the collecting bag specifically includes at least three support rods 610. These three support rods are arranged in an umbrella shape and extend downward and outward at the lower ends. At the same time, a lever 620 is provided at the lower end of the support rod. The middle part of the lever is elastically hinged to the lower end of the support rod through an elastic hinge. And it should be noted that the lower end of the lever is located inside and is connected to the edge of the lower open mouth of the collecting bag, while the upper end of the lever is located outside. And due to the action of the elastic hinge, the lever has a tendency to turn inward and upward at the lower end, so as to ensure that the passing area of the circle falling on the lower ends of the three levers is smaller than the body cross-section of the captured pests, that is, when the lever is in the upward-turning state, the pests entering the collecting bag will not be able to run out from the lower open mouth. In order to open the open mouth of the collecting bag regularly so that the pests in the collecting bag can be poured out from the opened open mouth. A motor B640 is also installed at the bottom of the tray. A traction rope 630 with the same number as the support rods is wound around the output shaft of the motor B. As Figure 1 shown, one end of the traction rope is connected to the outer end of the lever. When the motor B winds up, it can apply a traction force to the traction rope 650, and then pull the lever to turn outward, and finally open the closed open mouth of the collecting bag through the lever.

[0042] In addition, it should also be noted that on the basis of the above method, in order to enable the lower open mouth of the collecting bag to shrink and close automatically when it is not pulled outward by the lever, an elastic rubber ring 510 with elasticity is also provided in a circle at the lower open mouth of the collecting bag 500. And correspondingly, the inner end of the lever is connected to the elastic rubber ring 510. When the lever turns outward under the traction of the traction rope, the inner end (lower end) of the lever pulls the elastic rubber ring to open, thereby realizing the control of the open and closed states of the lower open mouth of the collecting bag.

[0043] It should be noted that, based on the above method, the degree of sealing of the lower opening of the collection bag can also be improved by the following method. Specifically, a circle of bristles 520 is arranged on the inner side of the elastic rubber ring. These bristles can be interwoven to form a dense mesh, completely sealing the sealed lower opening of the collection bag. When the inner end of the pry bar is tilted downward and outward, the elastic rubber ring connected to it is pulled outward, and the bristles connected to the inner side of the elastic rubber ring also retreat outward, ensuring that the bag opening can be opened smoothly.

[0044] Finally, it should be noted that in order to conveniently fix the present solution on the branches of the pear tree, a hanging ring 700 can be provided on the tray.

[0045] Working Principle: When it is necessary to control pear tree pests, especially the pear borer, the fruit farmer hangs the hanging ring of this solution on the pear tree and then activates the electronic control component. The electronic control component then energizes the power grid, creating a high voltage difference between the internal and external power grids. When the pear borers in the pear orchard are lured over, they are electrocuted on the power grid and fall into the collection bag below. It should be noted that in this solution, some larger pear borers may become stuck between the power grids and be unable to fall. In this case, the lever in the cleaning mechanism will be able to promptly remove the stuck pear borers from the external power grid during its circular motion, keeping the external power grid clean.

[0046] After a period of collection (2-3 days during the peak season and 7-15 days during the low season), the number of pests in the collection bag will reach a certain level, at which point the dead insects in the collection bag need to be promptly cleaned out. Furthermore, motor B starts and pulls the traction rope, which in turn drives the pry bar upward and opens the lower opening of the collection bag. The dead insects in the collection bag naturally fall to the bottom, thus achieving automatic cleaning of the collection bag. This structure can greatly reduce the frequency of workers maintaining the trap, reducing the workload of fruit farmers.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
