Description

Technical Field

[0001] The invention relates to the technical field of stored-grain pest control, and in particular to a wall trapping and killing device for stored-grain pests. Background Art

[0002] Pests are one of the important factors in grain storage safety. A large number of pests will eat a large amount of grain, causing a reduction in grain production during the storage process.

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

[0004] There are many kinds of traditional pest traps, including grain surface pest traps for grain surface pests and flying pest traps for flying pests. These pest traps all use some inherent habits of pests to trap pests. Some pests have the habit of crawling along the wall, and there is no suitable trapping device in the prior art that can trap pests with such habits. Summary of the invention

[0005] The object of the present invention is to provide a wall trapping device for stored-grain pests, which can trap and kill the pests by utilizing the habit of the pests to crawl along the wall.

[0006] In order to solve the above technical problems, the technical solution of a wall trapping device for stored-grain pests in the present invention is as follows: A wall trapping device for stored-grain pests comprises a device support, on which a rotating shaft arranged in parallel with the wall is rotatably mounted, a plurality of partitions radiatingly distributed with the rotating shaft as the center are fixed on the rotating shaft, end plates are arranged at both ends of the partitions, and a pest trapping space is formed between adjacent partitions, wherein the pest trapping space adjacent to the wall is a working pest trapping space, the pest trapping space adjacent to the upper side of the working pest trapping space is a preparatory pest trapping space, and the pest trapping space adjacent to the lower side of the working pest trapping space is a pest corpse collection space, a pest trapping channel for pests to crawl through from bottom to top is provided between the outer periphery of the partition on the lower side of the working pest trapping space and the wall, when the pests in the working pest trapping space reach a threshold, the rotating shaft rotates under the action of the weight of the pests, and the preparatory pest trapping space rotates to the position of the working pest trapping space, and the wall trapping device also comprises an insecticide supply device for replenishing insecticide in the preparatory pest trapping space.

[0007] Furthermore, the device bracket includes a front support plate of the rotating shaft connected to the front end of the rotating shaft and a rear support plate of the rotating shaft connected to the rear end of the rotating shaft. The front support plate of the rotating shaft and the rear support plate of the rotating shaft are both inclined plate structures arranged obliquely with respect to the vertical direction. The lower ends of the front support plate of the rotating shaft and the rear support plate of the rotating shaft have support plate connecting parts for connecting to the wall.

[0008] Furthermore, the wall trapping device also includes a pest guide plate fixed on the wall, the pest guide plate is located on the upper side of the partition on the lower side of the working pest trapping space, and the pest guide plate has a first guide slope extending gradually upward from left to right for guiding pests into the working pest trapping space.

[0009] Furthermore, the insecticide supply device includes an insecticide storage box for fixing on the wall, the insecticide storage box is located on the upper side of the prepared pest trapping space, the bottom of the insecticide storage box is hinged with a medicine dispensing plate whose rotating axis extends in the front-to-back direction, a medicine dispensing plate pull rope is connected between the insecticide storage box and the medicine dispensing plate, the right end of the medicine dispensing plate extends to the upper side of the prepared pest trapping space, a medicine dispensing hole is provided on the medicine dispensing plate on the upper side of the prepared pest trapping space, and a bottom channel for conveying insecticide through the upper surface of the medicine dispensing plate to the medicine dispensing hole is provided at the bottom of the insecticide storage box.

[0010] Furthermore, a medicine spreading plate push plate which is gradually inclined upward from left to right is provided at the right end of the medicine spreading plate. When the rotating shaft rotates in the forward direction, the upper end of the partition on the right side of the prepared pest killing space pushes the medicine spreading plate push plate to make the medicine spreading plate rotate around its own hinge axis.

[0011] Furthermore, a medicine distribution plate central axis with an axis extending in the front-to-back direction is fixed at the left end of the medicine distribution plate, and a medicine distribution channel is arranged in the medicine distribution plate central axis. The medicine distribution channel has a channel outlet and a channel entrance extending to the outer peripheral surface of the medicine distribution plate central axis, and the channel outlet is located on the upper side of the upper surface of the medicine distribution plate. When the medicine distribution plate pull rope is straightened under the action of the gravity of the medicine distribution plate, the upper end of the medicine distribution plate central axis blocks the bottom channel; during the forward rotation of the rotating shaft, the medicine distribution plate is pushed by the corresponding partition plate so that during the forward rotation of the medicine distribution plate central axis, the channel entrance can be connected with the bottom channel.

[0012] The beneficial effects of the present invention are as follows: when the present invention is in use, the rotation shaft and the device frame are positioned by friction, and the habit of pests to climb along the wall is utilized. The pests climb along the wall, and enter the working pest trapping space through the pest trapping channel. The pests are killed by pesticides in the working pest trapping space. As the number of pests in the working pest trapping space increases, the weight of the pest corpses will increase, and the torque acting on the rotation shaft by the pest corpses will increase. When it is sufficient to overcome the friction between the rotation shaft and the device frame, the rotation shaft will rotate forward, and the preparatory pest trapping space will rotate to the working pest trapping space position to carry out a new round of pest trapping. The pests rotated to the pest corpse collection space position can be collected by the staff using bags or boxes to achieve cyclic trapping of pests. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] 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.

[0015] 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.

[0016] An embodiment of a wall trapping device for storing grain pests of the present invention is as follows: Figures 1 to 6 As shown: it includes a device frame, on which is rotatably equipped a rotating shaft 15 arranged parallel to the wall, the axis of the rotating shaft 15 extends along the front-to-back direction, and a plurality of partitions 4 are fixed on the rotating shaft and are radially distributed with the rotating shaft as the center. In this embodiment, there are six partitions 4, and the angle between two adjacent partitions 4 is 60°. A pest trapping space 14 is formed between adjacent partitions, and the cross-section of the pest trapping space 14 is a fan-shaped structure, wherein the pest trapping space adjacent to the wall is a working pest trapping space 3, the pest trapping space adjacent to the upper side of the working pest trapping space 3 is a preparatory pest trapping space 12, and the pest trapping space adjacent to the lower side of the working pest trapping space 3 is a pest corpse collection space 23.

[0017] In this embodiment, the device bracket includes a front shaft support plate 16 connected to the front end of the shaft and a rear shaft support plate 21 connected to the rear end of the shaft. The front shaft support plate 16 and the rear shaft support plate 21 are both inclined plate structures inclined to the vertical direction. The lower ends of the front shaft support plate and the rear shaft support plate have a support plate connecting portion 22 for connecting to the wall. The support plate connecting portion is a connecting plate structure arranged in parallel with the wall. When in use, the connecting plate can be fixed to the wall 1 by bonding or nailing.

[0018] There is a pest trapping channel 2 between the outer periphery of the partition at the lower side of the working pest trapping space and the wall surface for pests to crawl through from bottom to top. When the pests in the working pest trapping space reach a threshold, the shaft rotates under the weight of the pests, and the prepared 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 prepared pest trapping space. The forward rotation in this embodiment refers to Figure 1 Counterclockwise rotation of the viewing angle.

[0019] The wall trapping device also includes a pest guide plate 5 for bonding and fixing on the wall, the pest guide plate is located on the upper side of the partition at the lower side of the working pest trapping space, the pest guide plate has a first guide slope 6 extending from left to right and gradually tilting upward for guiding the pests into the working pest trapping space, and the pest guide plate also has a second guide slope 22 located at the right end of the first guide slope and gradually tilting downward from left to right. When in use, the pest crawls from bottom to top through the pest trapping channel, then crawls along the guide slope toward the working pest trapping space, and then falls into the working pest trapping space 3.

[0020] The insecticide supply device includes an insecticide storage box 8 for fixing on the wall, the insecticide storage box 8 is located on the upper side of the prepared pest trapping space 3, the bottom of the insecticide storage box 8 is hinged with a medicine distribution plate 10 whose rotation axis extends in the front-to-back direction, a medicine distribution plate pull rope 9 is connected between the insecticide storage box 8 and the medicine distribution plate 10, the right end of the medicine distribution plate extends to the upper side of the prepared pest trapping space 12, a medicine distribution hole 11 is provided on the medicine distribution plate on the upper side of the prepared pest trapping space, and a bottom channel 20 for conveying insecticide through the upper surface of the medicine distribution plate to the medicine distribution hole is provided at the bottom of the insecticide storage box.

[0021] In this embodiment, a medicine-dispensing plate push plate 13 which is gradually inclined upward from left to right is provided at the right end of the medicine-dispensing plate. When the rotating shaft rotates in the positive direction, the upper end of the partition on the right side of the prepared pest trapping space pushes the medicine-dispensing plate push plate 13 to make the medicine-dispensing plate rotate around its own hinge axis. Figure 1 From a certain perspective, under the pushing action of the upper end of the corresponding partition 4, the medicine distribution plate can rotate counterclockwise around its own axis, and the outer end of the partition is an arc-shaped structure that is convenient for pushing.

[0022] A medicine distribution plate central axis 7 whose axis extends in the front-to-back direction is fixed at the left end of the medicine distribution plate. A medicine distribution channel 17 is arranged in the medicine distribution plate central axis 7. The medicine distribution channel 17 has a channel outlet 18 and a channel inlet 19 extending to the outer peripheral surface of the medicine distribution plate central axis. 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 upper surface of the medicine distribution plate. When the right end of the medicine distribution plate naturally droops under the action of the medicine distribution plate pull rope, the upper end of the medicine distribution plate central axis blocks the bottom channel. During the forward rotation of the rotating shaft, the medicine distribution plate is pushed by the corresponding partition plate so that during the forward rotation of the medicine distribution plate central axis, the channel inlet 19 can be connected with the bottom channel 17 through the channel inlet.

[0023] When using, Figure 1In this state, under the gravity of the medicine plate, the medicine plate pull rope 9 is straightened. At this time, the bottom channel is blocked by the outer peripheral surface of the upper end of the central axis of the medicine plate, and the insecticide in the insecticide storage box cannot flow to the upper plate surface of the medicine plate through the medicine distribution channel, and then cannot fall into the prepared pest trapping space through the medicine distribution hole. This is to avoid excessive flow of a large amount of insecticide into the prepared pest trapping space during the normal pest trapping process, resulting in a waste of insecticide, which is not conducive to the long-term use of the wall trapping device. Taking advantage of the habit of pests to crawl along the wall, the pests crawl to the pest guide plate through the pest trapping channel, and then crawl along the lower plate surface of the pest guide plate to the working pest trapping space, where the pests are quickly killed by the pesticide. When the pest corpses accumulate to a certain threshold, the torque generated by the pest 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 medicine dispensing plate push plate 13, and the rotating shaft 15 will rotate forward, and the working pest trapping space will rotate to the position of the pest corpse collection space at the bottom, and the pests will slide down under the action of their own weight. The operator can come to collect the pest corpses regularly, or an alarm and an encoder for detecting the rotation angle of the rotating shaft can be set. When the encoder detects that the rotating shaft is rotating, the alarm will sound, and the operator will come to collect the fallen pest corpses.

[0024] When the shaft rotates forward, the partition on the right side of the prepared pest trapping space will push the right end of the medicine dispensing plate, causing the medicine dispensing plate to rotate counterclockwise around its own axis. During the rotation of the medicine dispensing plate with the central axis of the medicine dispensing plate, the channel entrance of the medicine dispensing channel will be connected with the bottom channel at the bottom of the insecticide storage box. The insecticide in the insecticide storage box will flow to the upper plate surface of the medicine dispensing plate through the bottom plate channel and the medicine dispensing channel, and then flow along the upper plate surface of the medicine dispensing plate to the medicine dispensing holes, and flow to the prepared pest trapping space and the pest trapping space on the right side of the prepared pest trapping space through the medicine dispensing holes. When the partition passes the lowest position of the medicine dispensing plate, the original prepared pest trapping space rotates to the working pest trapping space position, and the medicine dispensing plate flips downward at the right end under the action of gravity, and there will be a moment when the channel entrance is connected with the bottom channel again, and the pest trapping space newly rotated to the position of the prepared pest trapping space will be dispensed with medicine again to ensure that its medicine amount meets the pest killing demand. When there are no dead insects on the partition, the partition on the right side of the prepared insect trapping space contacts the bottom of the medicine spreading plate push plate at the right end of the medicine spreading plate to limit the rotation of the shaft, and a new round of insect trapping operation is started.
