Abstract
Description
Technical Field
[0001] This invention relates to the field of armyworm rearing equipment technology, specifically to an armyworm rearing and screening device. Background Technology
[0002] Armyworms are voracious migratory pests that damage over 104 species of plants from 16 families. They are characterized by their large consumption, high reproductive rate, strong adaptability, and ability to cause outbreaks. When screening new pesticides and conducting physiological and biochemical experiments, it is necessary to regularly provide large numbers of standard test insects with uniform development. Furthermore, they can serve as an indispensable intermediate host for the large-scale artificial breeding of certain parasitic wasps. For example, armyworms have been used as a substitute host to breed the natural enemy of young bollworm larvae—the red-sulphur wasp—and this has promoted the commercial production of this wasp. Therefore, there is an urgent need in production to establish stable indoor populations of armyworms and to develop a simple and easy-to-use artificial breeding system for armyworms.
[0003] In the breeding of armyworms using the red-slit parasitic wasp as a natural enemy, after sieving the second-instar armyworm larvae inoculated 24 hours prior, unparasitized larvae must be removed daily to prevent competition for food between unparasitized and parasitized armyworms. The traditional sieving method involves pouring the armyworms from the rearing bag onto a sieve, shaking the sieve for manual sieving, and then transferring the sieving larvae into separate rearing bags. Due to the large-scale rearing of armyworms, this traditional manual sieving method requires a significant amount of work.
[0004] Existing technology includes a screening device, patent application number 201921058820.0, entitled "Screening Device for Armyworm Larvae." This device uses an air pump to blow air at the same speed onto armyworms of different sizes and weights. The different armyworms fall along different trajectories under the influence of the air, thus achieving screening. Although this screening device has a simple structure, its efficiency is low because the weight difference between armyworms of different sizes is not significant, relying solely on air power for screening. Another existing screening device, patent application number 201621257451.4, entitled "Screening Device for Armyworm Larvae Rearing," uses a screen with adjustable aperture between two rearing areas to separate armyworms of different ages. However, adjusting the screen can easily crush the armyworms, leading to mass mortality after decay. In conclusion, traditional screens are still necessary for screening. However, existing automated screening devices using traditional sieves are mostly complex in structure, expensive, and laboratory personnel cannot assemble the sieve devices themselves as needed.
[0005] Therefore, it is essential to design a low-cost, simple-structure, automatic batch screening device that can automatically pack armyworms into rearing bags after screening. Summary of the Invention
[0006] The purpose of this invention is to provide a sieve device for raising armyworms. This sieve device can automatically sieve armyworms in batches and can also automatically pack the armyworms into sieve bags after sieving.

[0011] Optionally, both the upper and lower sides of the interior of the first screening frame and the second screening frame are provided with slide rails, and both the upper and lower sides of the first screen and the second screen are provided with sliders that cooperate with the slide rails. The sliders are embedded in the slide rails, and the length of the sliders is less than the length of the slide rails. The sliders and the slide rails are used to cooperate with the horizontal reciprocating motion of the first screen and the second screen.
[0012] Optionally, the first screen is composed of a plurality of first screening grids, the bottom surface of the first screening frame is provided with a plurality of first hook and loop fasteners, and the top surface of the first screening frame is provided with a plurality of first support rods, each of the first hook and loop fasteners and each of the first support rods corresponding to each of the first screening grids; the second screen is composed of a plurality of second screening grids, the bottom surface of the second screening frame is provided with a plurality of second hook and loop fasteners, and the top surface of the second screening frame is provided with a plurality of second support rods, each of the second hook and loop fasteners and each of the second support rods corresponding to each of the second screening grids.

[0016] Optionally, the opening direction of the first screening frame is opposite to the opening direction of the second screening frame.
[0017] According to specific embodiments provided by the present invention, the present invention discloses the following technical effects:
[0018] The armyworm rearing and screening device provided by this invention screens armyworms by setting a first screening unit, a second screening unit, and a feces collection unit on a support frame. Unparasitized armyworms remain on the first screening unit, while parasitized armyworms fall onto the second screening unit. Feces and food residue fall into the feces collection unit. A first telescopic motor is installed in the first screening unit, and a second telescopic motor is installed in the second screening unit. The first telescopic motor drives the first screen to reciprocate horizontally, and the second telescopic motor drives the second screen to reciprocate horizontally, thus achieving automatic batch screening of armyworms.
[0019] The first screening rack has one side connected to the first frame with a buckle, and the second screening rack also has one side connected to the second frame with a buckle. The buckles are electromagnetic buckles. When the power is on, the buckles lock to screen the sticky insects. When the power is off, the buckles release, and the first and second screening racks flip downwards. Insect-raising cloth bags are pre-installed on the first and second screening racks. During the flipping process, the screened sticky insects are poured into the insect-raising cloth bags.
[0020] The first and second fixing plates are inclined, supporting the first and second screening frames after they are flipped downwards. This allows the armyworms to be poured into the insect rearing bag without causing the screening device to tip over due to an excessively large flipping angle. Furthermore, to ensure the overall balance of the screening device, the opening direction of the first screening frame is set to be opposite to that of the second screening frame.
[0021] The first and second pull rods, rollers and corresponding tracks, as well as slides and corresponding sliders, are made of a simple and low-cost device that can both cooperate with the horizontal reciprocating motion of the first and second telescopic motors and provide support and reinforcement for the first and second screens.
[0022] The area of the tray is larger than the area of the second screen, which is larger than the area of the first screen, to ensure that the sticky insects do not fall outside during the sieving process from top to bottom.
[0023] The first screen is divided into several first screening grids, and the second screen is divided into several second screening grids. Each screening grid corresponds to a bag of sticky insects, thus achieving batch screening of sticky insects. Attached Figure Description

The other end of the first screen 222 is fixedly connected to one end of the first telescopic motor 223, and the other end of the first telescopic motor 223 is fixedly connected to the frame of the first screening frame 22. A roller 224 and a corresponding track 225 are provided at the connection between the first screening frame 22 and the first pull rod 221. One end of the second pull rod is rotatably connected to the frame of the second screening frame 32, and the other end of the second pull rod is fixedly connected to one end of the second screen. The other end of the second screen is fixedly connected to one end of the second telescopic motor, and the other end of the second telescopic motor is fixedly connected to the frame of the second screening frame 32. A roller 224 and a corresponding track 225 are provided at the connection between the second screening frame 32 and the second pull rod. The upper and lower sides of the interior of the first screening frame 22 and the second screening frame 32 are provided with slide rails 226. The upper and lower sides of the first screen 222 and the second screen are provided with sliders 227 that cooperate with the slide rails 226. The sliders 227 are embedded in the slide rails 226. The length of the sliders 227 is less than the length of the slide rails 226. The sliders 227 and the slide rails 226 are used to cooperate with the horizontal reciprocating motion of the first screen 222 and the second screen.
[0035] Furthermore, the first screen 222 is composed of several first screening grids, and the bottom surface of the first screening frame 22 is provided with several first hook and loop fasteners (not shown in the figure). The top surface of the first screening frame 22 is provided with several first support rods 228, and each first hook and loop fastener and each first support rod 228 corresponds one-to-one with each first screening grid. The second screen is composed of several second screening grids, the bottom surface of the second screening frame 32 is provided with several second hook and loop fasteners, and the top surface of the second screening frame 32 is provided with several second support rods, each second hook and loop fastener and each second support rod corresponds one-to-one with each second screening grid. The mesh count of the first screen 222 is 10, and the mesh count of the second screen is 20. The area of the second screen is larger than the area of the first screen 222, and the area of the second screening grid is larger than the area of the first screening grid. The fecal collection unit 4 includes a tray 41, and the area of the tray 41 is larger than the area of the second screen. The structure of the second screening frame 32 is the same as that of the first screening frame 22, and will not be described again here.
[0036] The process of using the worm rearing and screening device provided by this invention is as follows: First, pull the first screening frame parallel to the first frame, open the switch of the first buckle, insert the locking tongue into the locking hole, and fix the first screening frame. Fix the second screening frame in the same way. Next, fix the worm rearing bags on the first and second screening frames, and open the openings of the worm rearing bags. Then, pour the worms from each worm rearing bag into each of the first screening grids, turn on the main switch of the worm rearing and screening device, and the first and second telescopic motors work simultaneously. The horizontal reciprocating motion of the first screen screens sieves the parasitized worms and feces onto the second screen screen, leaving the unparasitized worms. The horizontal reciprocating motion of the second screen screen sieves the feces onto the tray, leaving the parasitized worms. Next, turn off the main switch of the armyworm rearing and screening device, and simultaneously close the switches of the first and second latches. The locking tongue will disengage from the locking hole, and the first and second screening frames will flip downwards. The armyworms on the first and second screens will be poured into the rearing bag. Use a small broom to sweep the armyworms stuck on the screens into the rearing bag, and then remove the rearing bags one by one and seal them. Remove the tray and empty the feces and food scraps.
[0037] This embodiment is merely an illustration of the concept and implementation of the present invention and is not intended to limit it. Under the concept of the present invention, technical solutions without substantial changes are still within the scope of protection.
