Description

Technical Field

[0001] The invention relates to the technical field of stored-grain pest trapping, and in particular to a stored-grain pest trap in a grain pile. Background Art

[0003] The stored-grain pest trap uses its special structure combined with luring measures to lure stored-grain pests into the interior, and then kills the pests through certain technical means, thereby achieving the trapping and killing of stored-grain pests. In addition to directly trapping and killing stored-grain pests, stored-grain pest traps can more easily and sensitively monitor the dynamic changes of grain pile pests in the early warning of stored-grain pests, providing a basis for the prediction and forecast of pests. However, there are relatively few stored-grain traps on the market for use in granaries, and some traps have complex structures and are not very practical.

[0004] CN113229262B discloses a trap for grain surface, which includes a trapping probe inserted into a grain pile, and a grain surface trapping part placed on the upper side of the grain pile surface when in use. However, the trap is not provided with a luring device, the trapping efficiency is low, and the trapping situation in the trap cannot be observed in time during operation.

[0005] CN110074080B discloses a pest trap for use in grain piles, which is a cylindrical structure with insect trapping holes in the wall and a light-emitting unit to attract pests. However, the trap relies on a light source to attract pests, and the light is difficult to penetrate and diffuse in the grain pile, so it is less practical.

[0006] CN113229261B discloses a grain pile trap, the trap body is cylindrical, with a trapping structure inside, and at least six trap wings distributed circumferentially around the trap body when in use, and insect trap holes are provided on the trap body and the wings. However, the trap is difficult to be effectively inserted into the grain pile only by relying on the bottom cone, and the structure is complicated. When in actual use, the wings are easily malfunctioned due to resistance from the grain pile.

[0007] In summary, it is necessary to develop a stored grain pest trap with a simple structure, strong practicality, high trapping efficiency, and the ability to observe the trapping situation in time, so as to solve the structural deficiencies of the existing grain pile traps, so as to achieve the trapping and monitoring and early warning of stored grain pests, and meet the green pest control in the grain storage field. Summary of the invention

[0008] The technical problem to be solved by the present invention is to provide a grain storage pest trap in a grain pile which has a simple structure, is easy to operate, is easy to install and disassemble, can trap pests efficiently, and can monitor the trapping status of pests in time.

[0009] The technical solution adopted by the present invention to solve its technical problem is: a grain storage pest trap in a grain pile, comprising a trap mounting seat, a trap main body insect attraction tube, a trap camera module and a trap bottom insect collecting cone head, wherein the trap mounting seat, the trap main body insect attraction tube, the trap camera module and the trap bottom insect collecting cone head are connected in sequence from top to bottom; an insect attraction hole for pests to pass through is opened on the cylinder wall at the upper end of the trap main body insect attraction tube, an attractant containing bottle and a bottle cap are arranged inside the lower end, a dispensing hole is arranged on the bottle cap, and a miniature electronic liquid level meter is arranged in the attractant containing bottle.

[0010] Furthermore, the top of the trap mounting seat is sealed and a T-shaped handle is provided at the upper end.

[0011] Furthermore, the diameter of the insect-attracting hole is 2 to 3 mm.

[0012] Furthermore, a splash-proof balancing ring is provided on the bottle cap, and the balancing ring is composed of an inner circle and an outer circle whose rotation directions are perpendicular and concentric, and the inner circle, the outer circle, the bottle cap and the cylinder wall are fixed by a rotating bolt.

[0013] Furthermore, a bracket is connected under the bottle cap to fix a miniature electronic liquid level gauge, and the miniature electronic liquid level gauge can be set with an alarm liquid level to give an alarm prompt when the attractant liquid level is too low.

[0014] Furthermore, the trap camera module includes a micro camera device, a mounting sleeve and a bracket, the mounting sleeve is fixed on the bracket, the micro camera device is installed on the mounting sleeve, the micro camera device has a night vision function or is equipped with a flash, can shoot the inside of the insect collecting cone head at the bottom of the trap, and can transmit data via Bluetooth to realize real-time viewing of the pest trapping situation.

[0015] Furthermore, an insect collecting cavity is provided inside the upper end of the insect collecting cone head at the bottom of the trap; the insect collecting cavity is a cone-shaped structure; and the structure below the insect collecting cavity is a solid structure.

[0016] Furthermore, an external spiral is provided on the outside of the insect collecting cone head at the bottom of the trap, and the bottom is a cone-tip structure.

[0017] Compared with the prior art, the present invention has the following beneficial effects: (1) The grain storage pest trap of the present invention abandons the commonly used integrated structure. Since the grain in the grain pile often carries a large amount of dust and some impurities, the integrated structure is not convenient for cleaning and checking the trapping situation. At the same time, the integrated structure fixes the function of the entire trap, and it is no longer possible to upgrade and expand its functions. The present invention adopts modular unit components, and the components are assembled by threads. The installation and disassembly are simple and convenient, and it is easy to clean the trap, check the trapping situation and identify the types of trapped pests. At the same time, when the trap needs to be upgraded due to subsequent technological advances, it only needs to be made into unit components of the same specifications to achieve functional upgrades and expansions.

[0018] (2) The setting of the attractant bottle can improve the efficiency of attracting pests by adding attractants. In order to prevent the liquid attractant from spilling during use, two concentric rings parallel to the bottle cap are set outside the bottle cap of the attractant bottle and inside the insect attractant tube. Both concentric rings can rotate and the rotation direction is perpendicular. When the trap is tilted at different angles, the two concentric rings rotate under gravity, so that the attractant bottle can always remain roughly horizontal. At the same time, in order to facilitate the operator to understand the remaining attractant, a miniature electronic liquid level gauge is set in the attractant bottle. When the attractant liquid level is lower than the set liquid level, a warning sound can be issued to remind the operator to replenish it in time.

[0019] (3) In order to facilitate operators to obtain a preliminary understanding of the trapping situation of stored grain pests without removing the trap and to reduce the workload of repeatedly extracting and inserting the trap, a trap camera module is installed in the trap. The camera module can take pictures of the interior of the insect collecting cone at the bottom of the trap through a miniature camera device with a night vision function or a flash light, and transmit data through Bluetooth to check the trapping situation in real time, so as to decide whether to stop using the trap.

[0020] (4) The insect collecting cone head at the bottom of the grain storage pest trap of the present invention is provided with an insect collecting cavity at the top to collect the pests. At the same time, the cone structure is adopted to increase the difficulty of pest escape and facilitate the use of grain storage protective agents such as inert powder. In addition to collecting the trapped pests, the more important function of the insect collecting cone head is to facilitate the installation and use of the trap, saving time and effort. It adopts a "small bottom and large top" structure and is provided with an external spiral, and the structure below the insect collecting cavity is solid. First, the contact area with the grain pile is minimized, and the inclined plane principle is used. When installing, the grain is discharged to the periphery of the trap through the external spiral of the insect collecting cone head at the bottom of the trap, thereby reducing the resistance of the trap during installation. Secondly, the weight of the insect collecting cone head is increased, saving the downward pressure during the implantation into the grain pile. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0023] Reference Figure 1 and Figure 2 A grain storage pest trap in a grain pile comprises a trap mounting base 1, a trap main body insect trap tube 2, a trap camera module 3 and a trap bottom insect collecting cone head 4, wherein the trap mounting base 1, the trap main body insect trap tube 2, the trap camera module 3 and the trap bottom insect collecting cone head 4 are sequentially connected by threaded assembly from top to bottom; an insect trap hole 201 for pests to pass through is provided on the cylinder wall at the upper end of the trap main body insect trap tube 2, an attractant containing bottle 202 and a bottle cap 203 are provided inside the lower end, a dispensing hole 204 is provided on the bottle cap 203, and a miniature electronic liquid level meter 205 is provided in the attractant containing bottle 202.

[0024] Reference Figure 1 and Figure 2 The top of the trap mounting seat 1 is sealed to prevent grains and impurities from falling into the trap, and a T-shaped handle 101 is provided at the upper end to facilitate force to assist in screwing in and out of the trap.

[0025] Reference Figure 1 and Figure 2 The diameter of the insect trap hole 201 is 2 to 3 mm. Within this diameter range, grains can be prevented from entering the trap while pests can pass through smoothly.

[0026] Reference Figure 2 and Figure 3The attractant holding bottle 202 is assembled with the bottle cap 203 through a thread, so as to add and replace the attractant. The dispensing hole 204 is arranged in the middle of the bottle cap 203 to accelerate the volatilization of the attractant, so as to allow the attractant to spread and attract the pests to move toward the trap. In order to prevent the attractant from splashing and contaminating the trap and the grain pile during operation, a splash-proof balance ring is specially arranged on the bottle cap 203. The balance ring is composed of two inner circles 206 and outer circles 207 with perpendicular and concentric rotation directions. The inner circle 206, the outer circle 207, the bottle cap 203 and the cylinder wall are fixed by a rotating bolt 208. The whole device can only rotate but cannot move. When the trap is tilted, under the action of gravity, the two concentric circles and the attractant holding bottle 202 will rotate to adapt to the tilt angle of the trap, so as to ensure that the attractant holding bottle 202 is basically in a balanced state. A bracket 209 is connected under the bottle cap 203 to fix the micro-electronic liquid level gauge 205. The micro-electronic liquid level gauge can be set with an alarm level to give an alarm prompt when the attractant liquid level is too low.

[0027] Reference Figure 1 , Figure 2 and Figure 4 The trap camera module 3 includes a micro camera device 301, a mounting sleeve 302 and a bracket 303. The mounting sleeve 302 is fixed on the bracket 303, and the micro camera device 301 is installed on the mounting sleeve 302. The trap camera module fixes the micro camera device 301 through the bracket 303 and the mounting sleeve 302. When in use, the micro camera device 301 can be embedded in the mounting sleeve 302. Since the trap is placed inside the grain pile in a dark environment, the micro camera device 301 needs to have a night vision function or a flash light, which can shoot the inside of the insect collecting cone head at the bottom of the trap below, and can transmit data via Bluetooth to realize real-time viewing of the pest trapping situation.

[0028] Reference Figure 1 and Figure 2 An insect collecting cavity 401 is provided inside the upper end of the insect collecting cone head 4 at the bottom of the trap. The cone-shaped structure is convenient for applying stored grain protective agents such as inert powder, while increasing the difficulty of pests escaping. The structure below the insect collecting cavity 401 is solid, so as to increase the weight of the trap and facilitate its implantation in the grain pile. An external spiral 402 is provided on the outside of the insect collecting cone head 4 at the bottom of the trap. The existence of the external spiral 402 can cooperate with the unique structure of the insect collecting cone head to discharge grains to the periphery of the trap through rotation. The bottom is a cone tip structure 403. The entire insect collecting cone head adopts a "small bottom and large top" design, which can effectively reduce the contact area with grains and reduce the resistance during insertion into the grain pile.

[0029] In this embodiment, the micro electronic liquid level meter 205 and the micro camera device 301 are both existing technologies and will not be described in detail here.

[0030] When in use, first coat the inside of the trap with polytetrafluoroethylene, then add the stored grain pest attractant, set the alarm level of the micro electronic liquid level gauge 205 and then install it back, embed the micro camera device 301 into the installation sleeve 302, consider whether to add the stored grain protective agent according to the purpose and needs of trapping, then assemble the trap mounting seat 1, the trap main body insect trap tube 2, the trap camera module 3 and the trap bottom insect collecting cone head 4 in sequence, and screw the trap vertically into the grain pile. Since pests have the characteristic of hiding, they will actively look for narrow gaps to hide, and the grain pile has a certain temperature. The added stored grain pest attractant will volatilize into the grain pile through the top distribution hole 204 of the attractant holding bottle 202, and then diffuse through the micro airflow in the grain pile, thereby further attracting the pests to move toward the trap. The entire trap is coated with polytetrafluoroethylene to form a smooth inner wall. When the pest enters the trap through the trapping hole, it will fall directly into the insect collecting cavity 401 of the insect collecting cone head 4 at the bottom of the trap and will find it difficult to escape. The pest can be killed by inert powder or the like, or it can be left unadded to trap the living pest. When the attractant liquid level is lower than the set liquid level, the micro electronic liquid level meter 205 will emit a warning sound to warn the operator to add the attractant. During the trapping process, the operator can view the trapping situation in real time through the micro camera device 301 to decide whether to terminate the use of the trap.
