Description

Technical Field

[0001] This invention belongs to the field of warehousing technology, specifically a grain silo with a multi-functional bait box for pest control. Background Technology

[0002] Storage pests are a general term for harmful insects that damage stored grains and their products. The presence of storage pests not only leads to the loss of grain quantity but also causes changes in grain quality and may even lead to the production of highly toxic and carcinogenic toxins, thereby endangering human health. According to statistics from the Food and Agriculture Organization of the United Nations, losses caused by storage pests account for 4% to 8% of the total stored grain volume worldwide each year, and in some countries, the losses can even reach 30%. Therefore, effective prevention and control of storage pests is of great practical significance in the field of reducing losses and preserving the quality of stored grains.

[0003] In grain barn pest control, bait boxes are typically placed in the barn to kill pests. However, existing control methods are limited and cannot address multiple pests. For example, when a device captures small insects, larger pests (such as beetles and rats) may damage or bypass the device, significantly reducing its effectiveness. There is a lack of a comprehensive solution that can simultaneously classify and manage multiple pest sizes by region. Traditional broad-spectrum spraying or poison baiting can easily spread pesticides into the grain storage area, posing risks of pesticide residues and accidental injury to non-target organisms. The lack of effective escape prevention mechanisms means that pests can survive and escape even after entering the device, reducing the efficiency of single-capture operations. Existing devices often pile all captured pests in one place, which can cause small insect carcasses to block passageways, hindering the entry and capture of larger pests. Furthermore, the devices lack a physical mechanism for automatically classifying pests by weight, leading to chaotic subsequent processing and potential device overload.

[0004] Therefore, we propose a barn with a multi-functional bait box for pest control to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing pest control methods, which are often limited by their reliance on single methods and inability to handle multiple pests. For example, when a device captures small insects, larger pests may damage or bypass the device, significantly reducing its effectiveness. There is a lack of comprehensive solutions that can simultaneously classify and manage pests of various sizes in different areas. Traditional broad-spectrum spraying or baiting methods can easily spread pesticides into grain storage areas, posing risks of pesticide residues and accidental injury to non-target organisms. Furthermore, the lack of effective escape prevention mechanisms means that pests can survive and escape even after entering the device, reducing the efficiency of single-capture operations. Existing devices typically pile all captured pests in one place, which can lead to small insect carcasses blocking passageways and hindering the entry and capture of larger pests. Additionally, the lack of a physical mechanism for automatic pest classification based on weight causes subsequent processing chaos and device overload. Therefore, this invention proposes a grain storage facility with a multi-functional bait box for pest control.

[0006] The objective of this invention can be achieved through the following technical solution: A grain silo is included, with a box body fixed to the inner wall of the silo by bolts. The box body has a first partition and a second partition arranged sequentially from top to bottom, dividing the interior of the box body into a first chamber, a second chamber, and a third chamber, thus achieving graded pest extermination. A lightweight screen flap is movably installed inside the first partition. A U-shaped baffle is provided between the first and second partitions. A heavy-duty flap is rotatably installed inside the U-shaped baffle. Both the lightweight screen flap and the heavy-duty flap are configured to have a first working state and a second working state. The weight of the pests falling on the lightweight screen flap and the heavy-duty flap causes the lightweight screen flap and the heavy-duty flap to switch between the first working state and the second working state. In the first working state, the lightweight screen flap and the heavy-duty flap are configured to close the first partition and the second partition respectively; In the second working state, the lightweight screen flap and the heavy-duty flap are set to open the first partition and the second partition respectively.

[0007] In a preferred embodiment of the present invention, two lightweight screen flaps are symmetrically arranged front and back. Both lightweight screen flaps are rotatably installed in the middle of the first partition via a first rotating rod. The left end of the first rotating rod is connected to the inside of the first partition via a miniature torsion spring. A limit block is provided on the upper surface of the lightweight screen flap near the first rotating rod, and the lower surface of one side of the limit block abuts against the first partition.

[0008] In a preferred embodiment of the present invention, the lightweight screen flap has a placement groove inside, and a small pest trapping plate is inserted into the placement groove. The upper surface of the lightweight screen flap has small pest sieve holes, and the small pest sieve holes are connected to the placement groove.

[0009] In a preferred embodiment of the present invention, a connecting block is inserted into the middle of the right end of the first partition, the left side of the connecting block abuts against the right ends of the two lightweight screen flaps, and a side door is hinged to the right end of the box body, the right end of the connecting block abuts against the left end of the side door.

[0010] In a preferred embodiment of the present invention, the interior of the U-shaped baffle is rotatably connected to the heavy-duty flap via a rotating shaft, the left end of the rotating shaft is rotatably connected to the U-shaped baffle via a small torsion spring, and the lower end of the heavy-duty flap is provided with a medium-sized pest sieve hole.

[0011] In a preferred embodiment of the present invention, the inner walls at the front and rear ends of the U-shaped baffle are respectively provided with a sealing guide platform one and a sealing guide platform two. The rear end of the sealing guide platform one abuts against the front end of the heavy-duty flap via a rubber pad, and the front end of the sealing guide platform two is located above the upper part of the heavy-duty flap.

[0012] In a preferred embodiment of the present invention, a discharge port is provided on the middle and rear side of the second partition, the rear end of the heavy-duty flap is located inside the discharge port, a guide plate is movably installed inside the second partition by a return spring, and the outer end of the guide plate abuts against the lower part of the heavy-duty flap, a guide groove is provided inside the guide plate, the upper rear end of the guide groove is the inlet, and the inlet is located below the medium-sized pest sieve hole, a medium-sized pest trapping chamber is provided at the bottom front end of the second partition, the front end of the guide groove is the outlet, and the outlet is located above the medium-sized pest trapping chamber.

[0013] In a preferred embodiment of the present invention, the inner walls of the left and right sides of the U-shaped baffle are provided with arc-shaped moving grooves, and there are four arc-shaped moving grooves. The upper and lower ends of the heavy-duty flip plate are provided with second rotating rods, and the left and right ends of the two second rotating rods are respectively located inside the four arc-shaped moving grooves.

[0014] In a preferred embodiment of the present invention, protrusions are provided on the left and right sides of the front end of the second partition, and grooves matching the protrusions are provided on the left and right sides of the front end of the guide plate.

[0015] In a preferred embodiment of the present invention, a funnel-shaped inlet is provided inside the upper end of the box body, and the neck of the funnel-shaped inlet is located in the middle of the first partition. A large pest trapping chamber is placed at the bottom of the box body, and the inlet of the large pest trapping chamber is located below the discharge port.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) Through the three-level linkage screening mechanism of lightweight screen flap, medium-sized pest screen hole and heavy-duty flap, combined with the threshold setting of different torsion springs, the pests are automatically guided to different killing chambers according to their weight, realizing the physical isolation and killing of the entire spectrum and classification of small insects such as rice weevils, medium pests such as beetles and large pests such as rats, which greatly improves the comprehensiveness and pertinence of prevention and control. (2) By setting up a relatively closed box, the extermination process is completed inside the box, forming a trap that only allows entry but not exit. This can accurately lure pests into the device, fundamentally avoiding direct contact between the pesticide and the grain, thus ensuring food safety. (3) Through the lightweight screen flap and medium-sized pest screen holes, small and medium-sized pests can be screened out, preventing them from all entering the bottom layer. This reduces the collection pressure of the third chamber and the large pest trapping chamber, allowing the large pest trapping chamber to focus more on capturing large pests.

[0020] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1 - Figure 6 As shown, a grain barn with a multi-functional bait box for pest control includes a grain barn 1. A box 2 is fixed to the inner wall of the grain barn 1 by bolts, making the box 2 easy to assemble and disassemble. It can be installed in different locations inside the grain barn 1, such as corners, door and window entrances, along pest passages, and under shelves, where pests are frequently active but far from the grain itself. The box 2 has a first partition 3 and a second partition 4 arranged from top to bottom. The first partition 3 and the second partition 4 divide the interior of the box 2 into a first chamber 5, a second chamber 6, and a third chamber 7. The first chamber 5 can trap and kill small pests, the second chamber 6 can trap and kill medium pests, and the third chamber 7 can trap and kill large pests, achieving graded pest control. The upper end of the box 2 has a funnel-shaped inlet 9, and the neck of the funnel-shaped inlet 9 is located in the middle of the first partition 3. The funnel-shaped inlet 9 forces the pests that enter to fall down, preventing them from returning along the same path. A lightweight screen flap 301 is movably installed inside the first partition 3. Two lightweight screen flaps 301 are symmetrically arranged front and back. Both lightweight screen flaps 301 are rotatably installed in the middle of the first partition 3 via a first rotating rod 302. The left end of the first rotating rod 302 is connected to the inside of the first partition 3 via a micro torsion spring 307. In its natural state, the lightweight screen flap 301 is in a horizontal state due to the action of the micro torsion spring 307, thus closing the first partition 3. At this time, pests cannot enter the second chamber 6. A limiting block 306 is provided on the upper surface of the lightweight screen flap 301 near the first rotating rod 302, and the side of the limiting block 306 is lower. The surface abuts against the first partition 3. The setting of the limiting block 306 can limit the lightweight screen flap 301 and the micro torsion spring 307, preventing the lightweight screen flap 301 from being over-opened when there is no external force. The interior of the lightweight screen flap 301 is provided with a placement groove 304, and a small insect trapping plate 305 is inserted into the placement groove 304. The upper surface of the lightweight screen flap 301 is provided with a small insect screen hole 303, and the small insect screen hole 303 is connected to the placement groove 304. The small insect trapping plate 305 is coated with a strong contact insecticide or has insect-specific bait placed on it. Insects that fall on the small insect trapping plate 305 are stuck or poisoned by eating it. A plug-in block 308 is inserted into the middle of the right end of the first partition 3. The left side of the plug-in block 308 abuts against the right ends of the two lightweight screen flaps 301. A side door 10 is hinged to the right end of the box 2. The right end of the plug-in block 308 abuts against the left end of the side door 10. When it is necessary to clean the inside of the box 2, the side door 10 is opened. Then, because the plug-in block 308 is plugged in, it is only necessary to remove the plug-in block 308 first, and then the small pest trapping plate 305 inside the lightweight screen flap 301 can be pulled out from the right side and replaced with a new one to improve the subsequent pest control effect. A U-shaped baffle 8 is provided between the first partition 3 and the second partition 4. A heavy-duty flap 801 is rotatably mounted inside the U-shaped baffle 8. The interior of the U-shaped baffle 8 is rotatably connected to the heavy-duty flap 801 via a rotating shaft 802. The left end of the rotating shaft 802 is rotatably connected to the U-shaped baffle 8 via a small torsion spring 803. The heavy-duty flap 801 is tilted via the small torsion spring 803, and the upper surface of the heavy-duty flap 801 is smooth, so that pests falling on the heavy-duty flap 801 will slide down, facilitating the graded capture and extermination of pests. The lower end of the heavy-duty flap 801 has a medium-sized pest sieve hole 804, which can screen out medium and small pests, reducing the entry of medium and small pests. The third chamber 7 reduces the pest collection pressure. The inner walls of the front and rear ends of the U-shaped baffle 8 are respectively equipped with a first sealing guide platform 805 and a second sealing guide platform 806. The rear end of the first sealing guide platform 805 abuts against the front end of the heavy-duty flap 801 through a rubber pad. The front end of the second sealing guide platform 806 is located above the upper part of the heavy-duty flap 801. The setting of the first sealing guide platform 805 and the second sealing guide platform 806 can guide the pests falling into the second chamber 6, so that the pests land stably on the upper surface of the upper end of the heavy-duty flap 801, avoiding the pests from landing directly on the upper surface of the lower end of the heavy-duty flap 801, thus avoiding the medium-sized pest sieve hole 804 and improving the graded pest control effect. A discharge port 401 is provided on the middle and rear side of the second partition 4. The rear end of the heavy-duty flip plate 801 is located inside the discharge port 401, so that when large pests are located on the upper surface of the lower end of the heavy-duty flip plate 801, the heavy-duty flip plate 801 can be smoothly flipped, allowing the large pests to fall into the third chamber 7 through the discharge port 401. A guide plate 402 is movably installed inside the second partition 4 via a return spring 403, and the outer end of the guide plate 402 abuts against the lower surface of the heavy-duty flip plate 801. The return spring 403 provides a return thrust to the guide plate 402, so that when the heavy-duty flip plate 801 flips, it can push the guide plate 402 into the second partition 4, preventing the guide plate 402 from blocking the rotation of the heavy-duty flip plate 801. After the heavy-duty flip plate 801 is reset, the guide plate 402 moves into the second partition 4. The guide plate 402 will also be reset under the action of the reset spring 403. The guide plate 402 has a guide groove 406 inside. The upper rear end of the guide groove 406 is the inlet, which is located below the medium-sized pest sieve hole 804. The front end of the guide groove 406 is the outlet, which is located above the medium-sized pest trapping chamber 407. When the medium-sized pests above the heavy-duty flip plate 801 slide down to the medium-sized pest sieve hole 804, the medium-sized pests will fall into the guide groove 406 through the medium-sized pest sieve hole 804. The front bottom of the second partition plate 4 is provided with a medium-sized pest trapping chamber 407, which is fixedly installed on the second partition plate 4 with bolts. The medium-sized pest trapping chamber 407 contains special bait, which can attract the guide groove 406. The pests inside move into the small and medium-sized pest capture chamber 407. When there are medium-sized pests inside the guide groove 406, the heavy-duty flap 801 flips, pushing the guide plate 402 forward. Then, the guide plate 402 returns to its original position under the action of the return spring 403, causing it to move rapidly back and forth, creating a certain amount of shaking. This, combined with the tilting guidance of the guide groove 406, helps guide the pests in the guide groove 406 more smoothly into the small and medium-sized pest capture chamber 407. The inner walls of both sides of the U-shaped baffle 8 are provided with arc-shaped moving grooves 807, and there are four arc-shaped moving grooves 807. The heavy-duty flap 801 has second rotating rods 408 inside at both the upper and lower ends. The left and right ends of the two second rotating rods 408... The heavy-duty flap 801 is positioned within four arc-shaped moving slots 807. These slots limit the rotation angle and direction of the flap, allowing it to rotate only clockwise. The second rotating rod 408 is not initially positioned at the end of the arc-shaped moving slot 807, allowing for a very small counter-clockwise rotation. When an insect lands on the upper surface of the flap, the impact of gravity causes it to tilt slightly counter-clockwise. The small torsion spring 803 then adjusts to the gravity and returns the flap to its original position, resulting in a slight swaying or vibration that further accelerates the insect's descent.The second partition 4 has protrusions 405 on both the left and right sides of its front end. The guide plate 402 has grooves 404 on both the left and right sides of its front end that match the protrusions 405. The grooves 404 provide space for the protrusions 405 to move, thus not affecting the horizontal movement of the guide plate 402. The protrusions 405, without affecting the horizontal movement of the guide plate 402, close the second partition 4, preventing pests from entering the groove at the return spring 403 when moving inside the guide groove 406. A large pest trapping chamber 11 is placed at the bottom of the box 2. The entrance to the large pest trapping chamber 11 is located below the discharge port 401, allowing large pests such as large rats to fall directly into the chamber. Bait is placed at the inner edge of the large pest trapping chamber 11. The bait can be changed according to the different pests in the area, making it more flexible and encouraging the entering pests to move towards the inner edge of the large pest trapping chamber 11, preventing them from remaining below the entrance and affecting subsequent capture. It should be noted that the drawer-type design of the small pest trapping plate 305, the easy-to-replace design of the medium and small pest trapping chambers 407 and the large pest trapping chambers 11 facilitate the regular cleaning of carcasses, prevent decay and odor, and the specifications of the micro torsion springs 307 and small torsion springs 803 can be selected according to the different pests of the grain varieties to achieve the best grading effect.

[0022] Both the lightweight screen flap 301 and the heavy-duty flap 801 are configured to have a first working state and a second working state. The weight of the pests falling on the lightweight screen flap 301 and the heavy-duty flap 801 causes the lightweight screen flap 301 and the heavy-duty flap 801 to switch between the first working state and the second working state. In the first working state, the lightweight screen flap 301 and the heavy-duty flap 801 are set to close the first partition 3 and the second partition 4 respectively. At this time, because the weight of the pests does not reach the limit of the micro torsion spring 307 or the small torsion spring 803, the lightweight screen flap 301 and the heavy-duty flap 801 will not flip or flip significantly, so the first partition 3 or the second partition 4 will not open. Then, the pests falling on the lightweight screen flap 301 and the heavy-duty flap 801 will be collected by the capture plates or capture chambers inside the first chamber 5 and the second chamber 6. In the second working state, the lightweight screen flap 301 and the heavy-duty flap 801 are set to open the first partition 3 and the second partition 4 respectively. At this time, because the size and weight of the pests exceed the limit of the micro torsion spring 307 or the small torsion spring 803, the lightweight screen flap 301 and the heavy-duty flap 801 are flipped significantly, causing the first partition 3 or the second partition 4 to open. Then the pests will fall directly into the second chamber 6 or the third chamber 7, so that the heavy-duty flap 801 can further screen the pests or the large pest capture chamber 11 can capture and kill the large pests.

[0023] When using this invention, the box 2 is installed in places where pests are frequently active but far away from the grain, such as the inner wall of the barn 1, corners, door and window entrances, pest passages, and under the shelves. When pests crawl into the inside of the box 2 through the funnel-shaped entrance 9, they will fall directly into the inside of the box 2. When pests land on the upper surface of the lightweight screen flap 301, the weight of the pests and the impact force during their fall will affect the lightweight screen flap 301. When the pests are small, the lightweight screen flap 301 will not flip or rotate significantly, causing the small pests to land on the surface of the lightweight screen flap 301 and then fall through the small pest sieve holes 303 into the small pest capture plate 305, where they are captured and killed. When the pests are too large to pass through the small pest sieve holes 303, their weight will cause the lightweight screen flap 301 to flip. The flipped lightweight screen flap 301 will then open the first partition 3, allowing the pests to fall down onto the heavy-duty flap 801. Because the surface of the heavy-duty flip plate 801 is smooth and it has baffles on its front and rear sides, pests that fall on the surface of the heavy-duty flip plate 801 will slide downwards. During the sliding process, they will pass through the medium-sized pest sieve hole 804. At this time, small and medium-sized pests will fall into the guide groove 406 of the guide plate 402 through the medium-sized pest sieve hole 804. Then, through the attractant emitted by the bait inside the small and medium-sized pest trap 407, the pests inside the guide groove 406 will crawl towards the small and medium-sized pest trap 407 until they fall into the small and medium-sized pest trap 407 and are killed by the insecticide inside the small and medium-sized pest trap 407. Pests exceeding the medium-sized pest sieve hole 804, such as large rats, will continue to slide down. When they slide to the upper surface of the lower end of the heavy-duty flap 801, they will press the lower end of the heavy-duty flap 801 downward, causing the heavy-duty flap 801 to rotate. This will then open the second partition 4, allowing large pests to fall directly into the large pest capture chamber 11, thus completing the graded extermination of pests.
