Description

Technical Field

[0001] This invention relates to the field of pest control technology for stored grain, and more particularly to a wall-mounted trapping device for pests in stored grain. Background Technology

[0002] Pests are a major factor affecting the safety of grain storage. A large number of pests can consume a lot of grain, leading to reduced grain production during storage.

[0003] Therefore, pest control is an important part of grain storage safety. In the existing technology, there are two main traditional methods of pest control. The first method is to use fumigation gas to fumigate the grain storage environment to kill pests. The second method is to use pest traps to trap and kill pests. Compared with fumigation, pest traps have lower pest control costs and do not require the use of chemical agents on the grain, making them more biological and environmentally friendly.

[0004] Traditional insect traps come in various forms, including those for surface pests and those for flying pests. These traps utilize the inherent habits of the pests to trap them. However, some pests have the habit of climbing walls, and there is currently no suitable trapping device for this type of pest. Summary of the Invention

[0005] The purpose of this invention is to provide a wall-mounted pest trapping device for grain storage that utilizes the habit of pests crawling along walls to trap and kill them.

[0006] To solve the above-mentioned technical problems, the technical solution of the wall-mounted trapping device for grain storage pests in this invention is as follows:

[0007] A wall-mounted insect trapping device for grain storage pests includes a support frame with a rotating shaft arranged parallel to the wall. Multiple partitions radially distributed around the shaft are fixed on the shaft, with end plates at both ends. Adjacent partitions form insect trapping spaces. The insect trapping space adjacent to the wall is the working insect trapping space, the insect trapping space above the working insect trapping space is the preparatory insect trapping space, and the insect trapping space below the working insect trapping space is the insect carcass collection space. The outer periphery of the partition below the working insect trapping space has an insect trapping channel between itself and the wall, allowing insects to crawl through from bottom to top. When the number of insects in the working insect trapping space reaches a threshold, the shaft rotates under the weight of the insects, causing the preparatory insect trapping space to rotate to the position of the working insect trapping space. The wall-mounted insect trapping device also includes an insecticide supply device for replenishing insecticide in the preparatory insect trapping space.

[0008] Furthermore, the device support includes a front support plate connected to the front end of the rotating shaft and a rear support plate connected to the rear end of the rotating shaft. Both the front and rear support plates are inclined plate structures that are inclined in the vertical direction. The lower ends of the front and rear support plates have support plate connecting parts for connecting to the wall.

[0009] Furthermore, the wall-mounted trapping device also includes a pest guide plate for fixing to the wall. The pest guide plate is located above the partition below the working pest trapping space. The pest guide plate has a first guide slope that gradually slopes upward from left to right to guide pests into the working pest trapping space.

[0010] Furthermore, the insecticide supply device includes an insecticide storage box for fixing to the wall. The insecticide storage box is located above the prepared pest trapping space. A distribution plate with a rotation axis extending in the front-back direction is hinged to the bottom of the insecticide storage box. A distribution plate pull rope is connected between the insecticide storage box and the distribution plate. The right end of the distribution plate extends to the upper side of the prepared pest trapping space. A distribution hole is provided on the distribution plate above the prepared pest trapping space. The bottom of the insecticide storage box is provided with a bottom channel for conveying insecticide through the distribution hole on the upper surface of the distribution plate.

[0011] Furthermore, the right end of the pesticide application board is equipped with a pesticide application board pusher plate that gradually tilts upward from left to right. When the rotating shaft rotates in the forward direction, the upper part of the partition on the right side of the prepared pest trapping space pushes the pesticide application board pusher plate, causing the pesticide application board to rotate around its own hinge axis.

[0012] Furthermore, a central axis extending along the front-rear direction is fixed to the left end of the medicine distribution plate. A medicine distribution channel is provided inside the central axis. The medicine distribution channel has a channel outlet and a channel inlet extending to the outer circumference of the central axis. The channel outlet is located on the upper side of the plate surface. When the medicine distribution plate pull rope is straightened under the gravity of the medicine distribution plate, the upper end of the central axis blocks the bottom channel. During the forward rotation of the shaft, the medicine distribution plate is pushed by the corresponding partition, so that the channel inlet can communicate with the bottom channel during the forward rotation of the central axis.

[0013] The beneficial effects of this invention are as follows: In use, the rotating shaft and the device frame are positioned by friction. Taking advantage of the insects' habit of climbing along walls, the insects climb along the wall and enter the working insect-trapping space through the insect trapping channel. The insects are killed by insecticide in the working insect-trapping space. As the number of insects in the working insect-trapping space increases, the weight of the insect corpses increases, and the torque exerted by the insect corpses on the rotating shaft increases. When this torque is sufficient to overcome the friction between the rotating shaft and the device frame, the rotating shaft will rotate forward, and the preparatory insect-trapping space will rotate to the working insect-trapping space position to carry out a new round of insect trapping. The insects that have rotated to the insect corpse collection space position can be collected by the staff using bags or boxes, realizing the cyclical trapping of insects.

[0022] To facilitate understanding of the present invention, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0023] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0024] An example of an embodiment of a wall-mounted trapping device for grain storage pests in this invention. Figures 1-6 As shown: The device includes a frame on which a rotating shaft 15 is rotatably mounted, arranged parallel to the wall. The axis of the rotating shaft 15 extends in the front-to-back direction. Multiple partitions 4 are fixed on the rotating shaft and distributed radially around the rotating shaft. In this embodiment, there are six partitions 4 in total. The included angle between two adjacent partitions 4 is 60°. A pest trapping space 14 is formed between adjacent partitions. The cross-section of the pest trapping space 14 is a fan-shaped structure. The pest trapping space adjacent to the wall is the working pest trapping space 3. The pest trapping space adjacent to the upper side of the working pest trapping space 3 is the preparatory pest trapping space 12. The pest trapping space adjacent to the lower side of the working pest trapping space 3 is the pest corpse collection space 23.

[0025] In this embodiment, the device bracket includes a front support plate 16 connected to the front end of the rotating shaft and a rear support plate 21 connected to the rear end of the rotating shaft. Both the front support plate 16 and the rear support plate 21 are inclined plate structures that are inclined to the vertical direction. The lower ends of the front support plate and the rear support plate have support plate connecting parts for connecting to the wall. The support plate connecting parts are connecting plate structures arranged in parallel with the wall. In use, the connecting plates can be fixed to the wall 1 by adhesive or nails.

[0026] The lower side of the working pest trapping space has a pest trapping channel 2 between the outer perimeter of the partition and the wall, allowing pests to crawl through from bottom to top. When the number of pests in the working pest trapping space reaches a threshold, the shaft rotates under the weight of the pests, and the pre-pest trapping space rotates forward to the position of the working pest trapping space. The wall trapping device also includes an insecticide supply device for replenishing insecticide in the pre-pest trapping space. In this embodiment, forward rotation refers to... Figure 1 Rotating counterclockwise from the perspective.

[0027] The wall-mounted insect trapping device also includes an insect guide plate 5 for adhesively fixing to the wall. The insect guide plate is located above the partition below the working insect trapping space. The insect guide plate has a first guide slope 6 that gradually slopes upward from left to right to guide the insects into the working insect trapping space. The insect guide plate also has a second guide slope 22 that gradually slopes downward from left to right at the right end of the first guide slope. In use, the insects crawl from bottom to top through the insect trapping channel, then crawl along the guide slope towards the working insect trapping space, and subsequently fall into the working insect trapping space 3.

[0028] The insecticide supply device includes an insecticide storage box 8 for fixing to the wall. The insecticide storage box 8 is located above the prepared pest trapping space. The bottom of the insecticide storage box 8 is hinged to a distribution plate 10 with a rotation axis extending in the front-back direction. A distribution plate pull rope 9 is connected between the insecticide storage box 8 and the distribution plate 10. The right end of the distribution plate extends to the upper side of the prepared pest trapping space 12. The distribution plate is provided with a distribution hole 11 on the upper side of the prepared pest trapping space. The bottom of the insecticide storage box is provided with a bottom channel 20 for conveying insecticide through the distribution hole on the upper surface of the distribution plate.

[0029] In this embodiment, the right end of the pesticide application plate is provided with a pesticide application plate pusher plate 13 that gradually tilts upward from left to right. When the rotating shaft rotates in the forward direction, the upper part of the partition on the right side of the prepared pest trapping space pushes the pesticide application plate pusher plate 13, causing the pesticide application plate to rotate around its own hinge axis. Figure 1 From the perspective of the upper part of the corresponding partition 4, the medicine distribution plate can rotate counterclockwise around its own axis under the pushing action. The outer end of the partition is an arc-shaped structure to facilitate pushing.

[0030] The left end of the medicine distribution plate is fixed with a central shaft 7 extending along the front-back direction. A medicine distribution channel 17 is provided inside the central shaft 7. The medicine distribution channel 17 has a channel outlet 18 and a channel inlet 19 extending to the outer circumference of the central shaft. The channel outlet 18 and the channel inlet 19 are arranged in a V-shape. The channel outlet 18 is located on the upper side of the medicine distribution plate surface. When the right end of the medicine distribution plate hangs down naturally under the action of the medicine distribution plate pull rope, the upper end of the central shaft of the medicine distribution plate blocks the bottom channel. During the forward rotation of the shaft, the medicine distribution plate is pushed by the corresponding partition, so that the channel inlet 19 can communicate with the bottom channel 20 through the channel inlet during the forward rotation of the central shaft of the medicine distribution plate.

[0031] When using, such as Figure 1 In this state, under the weight of the pesticide distribution board, the pull rope 9 of the distribution board is straightened. At this time, the bottom channel is blocked by the outer circumference of the upper end of the central axis of the distribution board. The insecticide in the insecticide storage box cannot flow through the distribution channel to the upper surface of the distribution board, and therefore cannot fall into the prepared pest trapping space through the distribution holes. This is to avoid excessive flow of insecticide into the prepared pest trapping space during the normal pest trapping process, which would cause waste of insecticide and be detrimental to the long-term use of the wall-mounted pest trapping device. Taking advantage of the insects' tendency to climb along walls, the insects crawl through the insect trapping channel to the insect guide plate, and then along the lower surface of the guide plate to the working insect trapping space. In the working insect trapping space, the insects are quickly killed by insecticide. When the insect corpses accumulate to a certain threshold, the torque generated by the insect corpses on the rotating shaft is sufficient to overcome the friction between the rotating shaft and the device frame and the force between the corresponding partition and the top push plate 13 of the pesticide distribution plate. The rotating shaft 15 will then rotate in the forward direction, and the working insect trapping space will rotate to the position of the lower insect corpse collection space. Under the action of its own weight, the insects will slide down. Operators can come to collect the insect corpses periodically. Alternatively, an alarm and an encoder for detecting the rotation angle of the rotating shaft can be set. When the encoder detects the rotation of the rotating shaft, the alarm will sound, and the operator will come to collect the fallen insect corpses.

[0032] When the shaft rotates clockwise, the partition on the right side of the prepared pest trapping space pushes the right end of the pesticide application board, causing the application board to rotate counterclockwise around its own axis. During the rotation of the application board along its central axis, the entrance of the application channel will connect with the bottom channel at the bottom of the insecticide storage box. The insecticide in the insecticide storage box will flow through the bottom channel and the application channel to the upper surface of the application board, and then along the upper surface of the application board to the application hole. Through the application hole, it will flow to the prepared pest trapping space and the pest trapping space to the right of the prepared pest trapping space. When the partition passes the lowest position of the application board, the original prepared pest trapping space rotates to the working pest trapping space position. Under the action of gravity, the right end of the application board flips downward, and the entrance of the channel will connect with the bottom channel again. The newly rotated pest trapping space will be pesticided again to ensure that the amount of pesticide meets the pest killing requirements. When there are no dead pests on the partition, the partition on the right side of the prepared pest trapping space comes into contact with the bottom of the top push plate of the pesticide application board at the right end of the application board, and the rotating shaft stops rotating, starting a new round of pest trapping operation.
