Description

Technical Field

[0001] This utility model relates to the field of fall armyworm trapping technology, specifically to a trapping device for fall armyworm. Background Technology

[0002] The fall armyworm is a highly destructive agricultural pest that has spread rapidly worldwide in recent years, posing a serious threat to crop growth and yield. This pest is characterized by its high reproductive capacity, rapid migration, and omnivorous diet, damaging various important food crops such as corn, rice, and wheat, resulting in significant economic losses to agricultural production. Traditional methods for controlling the fall armyworm mainly include chemical control, biological control, and physical control. While chemical control is highly effective, long-term use can lead to increased pesticide resistance in pests and also pollute the environment, disrupting the ecological balance. Biological control utilizes natural enemy insects and microorganisms to control pest populations; although it has advantages such as being environmentally friendly and sustainable, it is often slow to take effect and is greatly affected by environmental factors. Physical control methods are relatively more environmentally friendly, with trapping devices being an important tool.

[0003] Currently, common methods for trapping fall armyworm include: pheromone trapping, which attracts male moths by releasing sex pheromones; light trapping, which uses their phototaxis to attract them; and chemical trapping, which uses bait containing medicated chemicals to kill them. However, these methods all have significant drawbacks. After pheromone and light trapping, the insects accumulate inside the trap, requiring regular manual cleaning, which not only increases labor costs but also can lead to bacterial growth and disease transmission if not cleaned in a timely manner. Chemical trapping can easily cause environmental pollution, promote pesticide resistance in pests, and affect the safety of agricultural products. Moreover, existing trapping devices are generally single-function and cannot effectively treat and utilize the trapped fall armyworms, resulting in resource waste. Therefore, developing a trapping device for fall armyworm is an urgent problem that needs to be solved. Utility Model Content

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0024] Reference Figure 1 and Figure 2 The illustration shows an embodiment of a trapping device for fall armyworm. The device mainly includes a cylinder 1, at least one crushing component 2, and multiple trapping components 3. The crushing component 2 is located inside the cylinder 1, and the trapping components 3 are connected to the upper part of the cylinder 1 and located above the crushing component 2. The trapping components 3 can efficiently trap fall armyworm, guide it into the crushing component 2 for crushing, and automatically discharge it for use as field fertilizer, avoiding manual cleaning and realizing the resource utilization and green control of pests.

[0025] Continue to refer to Figure 1 and Figure 2 The cylinder 1 is vertically arranged and has a cylindrical structure. Multiple through holes 101 are arranged circumferentially on its upper part, serving as channels for the fall armyworm to enter the interior of the cylinder 1. These through holes 101 effectively receive the pests guided by the trapping component 3. There are four through holes 101, but the number can be configured as needed, such as two, five, or six. Multiple outlets 102 are arranged circumferentially on the lower part of the cylinder 1. There are four outlets 102, evenly distributed on the lower circumferential wall of the cylinder 1, used to directionally discharge the fall armyworm material crushed by the internal crushing component 2, thereby achieving resource utilization.

[0026] The device includes a base 104 at the bottom of the cylindrical body 1. The diameter of the base 104 is larger than that of the cylindrical body 1 to increase the contact area between the device and the ground, thereby improving overall stability. The base 104 has multiple support feet 104a at its bottom. These support feet 104a can directly support the device on flat ground, and when the device is used in a field setting, they can insert into the soil, enhancing the device's resistance to overturning in complex terrain and natural environments through interlocking with the soil, ensuring the device's stability.

[0027] Refer to Figure 2 At least one crushing component 2 is provided inside the cylinder 1 and located below the through hole 101. In this embodiment, there are two crushing components 2. The two crushing components 2 are arranged at a certain interval along the height direction of the cylinder 1. The number of crushing components 2 can be configured according to the degree of crushing, such as one, three, four, etc.

[0028] The crushing assembly 2 includes a rotating assembly 201 and a fixed assembly 202 arranged in series. The rotating assembly 201 is located above the fixed assembly 202 and can rotate relative to it. When two crushing assemblies 2 are installed, the two fixed assemblies 202 are fixed to the inner wall of the cylinder 1 by welding, bolting, or other fixing methods to provide a stable support foundation. The synchronous rotation of the two rotating assemblies 201 relative to the fixed assembly 202 achieves two-stage crushing of the fall armyworms falling into the cylinder 1. Through multiple crushing operations, the crushing effect is effectively improved, ensuring that the fall armyworms can be fully crushed into materials that meet the requirements for subsequent discharge and utilization.

[0029] Specifically, the rotating assembly 201 includes a rotating shaft 201a coaxially arranged with the cylinder 1 and two rotating arms 201b. The upper end of the rotating shaft 201a is rotatably located in a shaft hole 103 formed in the top of the cylinder 1. The two rotating arms 201b extend radially from the circumferential wall of the rotating shaft 201a towards the side wall of the cylinder 1 and are symmetrically arranged on both sides of the rotating shaft 201a, which helps maintain the balance of the rotating assembly 201 during rotation. At the bottom of the two rotating arms 201b, eight crushing components 201c are respectively arranged, with four crushing components 201c arranged in each rotating arm 201b. The crushing components 201c are specifically cutters, extending vertically downwards. Of course, the number of rotating arms 201b and crushing components 201c can be configured as needed; for example, increasing the number of rotating arms 201b and crushing components 201c can improve crushing efficiency, or reducing the number can accommodate smaller processing volumes and limited space.

[0030] The fixing assembly 202 includes a support 202a fixed to the inner wall of the cylinder 1 and a plurality of annular members 202b fixed to the support 202a and coaxially arranged. The crushing components 201c are staggered with the plurality of annular members 202b, and the interval between each crushing component 201c and two adjacent annular members 202b corresponds to the interval defined as an annular through groove. The support 202a includes a central column 202a1 and a plurality of support rods 202a2, and a rotating shaft 201a is rotatably fitted onto the middle of the central column 202a1. Multiple support rods 202a2 extend radially towards the side wall of the cylinder 1 along the circumferential wall of the central column 202a1. One end of each support rod 202a2 is fixed to the central column 202a1 by welding, riveting, or other means, and the other end is fixed to the side wall of the cylinder 1 by bolts, clips, or other connection methods, thereby installing the support 202a on the inner wall of the cylinder 1 and providing a supporting foundation for the annular component 202b. The multiple annular components 202b have different diameters and are fixed to the multiple support rods 202a2 at certain intervals around the central column 202a1 and along the length direction of the support rods 202a2. Specifically, there are four support rods 202a2, evenly distributed on the circumferential wall of the central column 202a1. Three annular components 202b are mounted on each support rod 202a2. Due to the different diameters of the annular components 202b, two annular grooves of different diameters are formed between adjacent annular components 202b. A cutter extends downwards and inserts into the annular grooves. When the rotating assembly 201 drives the cutter to move circumferentially, the cutter rotates at high speed within the annular grooves, causing the fall armyworms falling onto the annular components 202b to be sheared and crushed by the interaction between the cutter and the annular components 202b. The crushed material then continues to fall through the annular grooves to the lower part of the cylinder 1 for subsequent discharge from the outlet 102, thus realizing the crushing and material transfer process for the fall armyworms.

[0031] Reference Figure 2 A scraping component 203 is provided at the lower end of the rotating shaft 201a and corresponds to the outlet 102. The scraping component 203 includes multiple scraping blades 203a, which extend radially from the outer wall of the rotating shaft 201a. Each scraping blade 203a is twisted to the left or right by an angle α (30-60 degrees) relative to the axial section of the rotating shaft 201a, guiding the crushed residue out of the outlet 102. By twisting the scraping blades 203a, when the rotating shaft 201a drives the scraping component 203 to rotate, the scraping blades 203a exert a directional pushing force on the crushed residue located at the bottom of the cylinder 1 during rotation. This directional force changes the trajectory of the crushed residue within the cylinder 1, guiding it in a predetermined direction to the outlet 102 corresponding to the scraping component 203, and thus smoothly discharging it outside the cylinder 1.

[0032] Reference Figure 2 A motor 4 is mounted on the upper end of the rotating shaft 201a and fixed to the top of the cylinder 1. Specifically, a bracket is provided on the top of the cylinder 1, and the motor 4 is fixed to the bracket. The motor 4 is connected to the upper end of the rotating shaft 201a via a coupling. A protective cover 401 is provided on the top of the cylinder 1. The protective cover 401 is installed on the top of the cylinder 1 by means of bolts, clips, or other detachable connections, completely enclosing the motor 4 within its internal space. This effectively prevents dust, rainwater, insects, and other impurities from the external environment from entering the motor 4, ensuring the normal operation of the motor 4. The outer wall of the protective cover 401 is provided with heat dissipation holes 401a to prevent the motor 4 from overheating due to heat accumulation, which would affect its performance and service life. A solar panel 402 is provided on the upper part of the protective cover 401 to achieve energy self-sufficiency of the device, reduce operating costs, and improve the applicability of the device in the field environment. A power source (not shown in the figure) is provided at the top of the cylinder 1. The power source is a rechargeable battery pack or other energy storage device. The power source is connected to the solar panel 402 and the motor 4 circuit through circuit connection lines to provide power support for the operation of the motor 4.

[0033] Reference Figure 1 and Figure 4 The trapping assembly 3 comprises four components, which are evenly distributed at 90° intervals along the circumferential wall of the cylinder 1 and are all located in the upper region of the cylinder 1, above the through hole 101 in the upper part of the cylinder 1. The trapping assembly 3 includes an attractant part 301 for attracting fall armyworms and a guide tube 302 connected to the bottom of the attractant part 301. The guide tube 302 is an arc-shaped pipe, and the outlet end of the guide tube 302 is connected to the through hole 101 in the upper part of the cylinder 1 to ensure that the fall armyworms can smoothly enter the inner cavity of the cylinder 1 through the curved path of the guide tube 302. The inner wall of the guide tube 302 has a smooth surface to prevent the fall armyworms from clogging the pipe.

[0034] The attractant 301 includes a shell 301a that is open at both the top and bottom. Multiple inlets 301a1 for receiving fall armyworms are provided on the circumferential wall of the shell 301a. The inlets 301a1 can be circular, square, or strip-shaped, and their size is designed to fit the body size of the fall armyworm, facilitating its easy entry into the shell 301a. In this embodiment, the inlets 301a1 are strip-shaped. The bottom of the shell 301a is connected to the inlet end of the guide tube 302 by means of threaded connection, snap-fit, or adhesive, thus forming a guide channel. The shell 301a is cylindrical, and the diameter of the guide tube 302 is smaller than the diameter of the shell 301a, causing the connection between the bottom of the shell 301a and the inlet end of the guide tube 302 to gradually narrow, which is beneficial for the pest to enter the guide tube 302. Meanwhile, the top of the housing 301a is provided with a detachable cover 301b. The cover 301b is connected to the housing 301a by a snap-on structure, threaded structure or magnetic structure, which makes it easy for operators to open the cover 301b to replace and maintain the internal components. At the bottom of the cover 301b, there is an absorbent cotton swab 301c for holding the attractant. The absorbent cotton swab 301c is made of highly absorbent fiber material, which can fully absorb and slowly release the attractant.

[0035] The attractant is selected from sex attractants, wherein the sex attractants are cis-9-tetradecene acetate and cis-7-dodecene acetate.
