Description

Technical Field

[0001] The invention relates to the field of yellow mealworm processing devices, and more particularly to a device for separating large and small mealworms and their excrement. Background Art

[0002] In existing techniques, mealworms undergo stages of varying sizes during their growth cycle, producing a large amount of feces. To improve breeding efficiency and product quality, it is necessary to separate mealworms of varying sizes and process the feces separately from the worm bodies. However, conventional mealworm separation methods present the following problems:

[0003] Low efficiency of manual screening: Traditional mealworm separation mostly adopts manual screening, which is not only labor-intensive but also inefficient and cannot meet the needs of large-scale breeding.

[0004] The machine screening method is generally to arrange multiple layers of parallel screens from top to bottom. During the vibration process, some mealworms at the front of the screen fall into the lower screen, and can be filtered more finely through the lower screen. However, some mealworms at the middle and rear sections of the upper screen fall into the lower screen. As a result, the mealworms are discharged without passing through the entire screening process of the lower screen, resulting in poor filtration effect and low efficiency.

[0005] Therefore, how to provide a new device for separating large and small mealworms and insect feces to ensure that mealworms of various sizes can be screened while ensuring that the mealworms screened out have a complete screening process in the next screening process is a problem that technical personnel in this field urgently need to solve.

The air blow pipe is also used to accelerate the transportation process of the screened mealworms and insect feces, and the invention has the characteristics of fine screening and high efficiency.

[0013] Preferably, it further comprises an insect excrement collecting box, which is arranged opposite to the discharge hole corresponding to the bottom screening unit.

DETAILED DESCRIPTION

[0032] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0033] See attached Figure 1-8 The embodiment of the present invention discloses a device for separating large and small mealworms and their feces, comprising: a frame 1, a multi-stage screening mechanism 2, a mealworm collecting box 3 and an air pump;

[0034] The multi-stage screening mechanism 2 includes three-stage screening units 21 arranged in a zigzag shape from top to bottom. The screening unit 21 includes a tray 211, a sieve plate 212, and a vibration motor 213. The tray 211 is arranged obliquely and is fastened to the frame 1. A discharge hole 2111 is provided at a low position inside the tray 211. The discharge hole 2111 is arranged opposite to the high position of the sieve plate 212 corresponding to the screening unit 21 located below. Blowing pipes 214 are provided on both sides of the tray 211 corresponding to its inclination direction. The blowing direction of the blowing pipes 214 is arranged toward the low position of the tray 211. The sieve plate 212 is located above the tray 211, arranged parallel to the tray 211, and elastically connected. The vibration motor 213 is fixedly connected to the sieve plate 212.

[0035] The mealworm collecting box 3 is located below the lower end of the sieve plate 212;

[0036] The output end of the air pump is connected to the air blowing pipe 214 through a pipeline.

[0037] Specifically, the screening unit 21 located at the top layer is used to screen large-sized mealworms, and the corresponding discharge holes 2111 discharge small and medium-sized mealworms and insect feces; the screening unit 21 located in the middle position is used to screen medium-sized mealworms, and the corresponding discharge holes 2111 discharge small-sized mealworms and insect feces; the screening unit 21 located at the bottom is used to screen small-sized mealworms, and the corresponding discharge holes 2111 discharge insect feces.

[0038] In some embodiments, an insect excrement collection box 4 is further included, and the insect excrement collection box 4 is arranged opposite to the discharge hole 2111 corresponding to the bottom screening unit 21. Therefore, after adding the insect excrement collection box 4, the insect excrement screened by the bottom screening unit 21 can be directly collected, avoiding mixing of the insect excrement with other materials, and achieving complete separation of the insect excrement and mealworms, facilitating subsequent separate processing and utilization, thereby improving resource utilization and the sanitation of the breeding environment.

[0039] In other embodiments, the sieve plate 212 and the tray 211 are elastically connected through an elastic component 215, and the elastic component 215 includes a support plate 1 2151, a support plate 2152 and a spring 2153. The support plate 1 2151 is fastened to the tray 211, the support plate 2152 is arranged opposite to the support plate 1 2151 and is fastened to the sieve plate 212, and the two ends of the spring 2153 are fastened to the opposite surfaces of the support plate 1 2151 and the support plate 2 2152 respectively.

[0040] In one embodiment, there are four elastic components 215, evenly distributed on both sides of the screen plate 212 along its inclination direction. Thus, the four elastic components 215, evenly distributed, can make the screen plate 212 more evenly stressed during vibration, reduce local stress concentration on the screen plate 212, further improve the stability and screening effect of the screen plate 212, ensure that the mealworms are evenly distributed and effectively screened on the screen plate 212, and avoid problems such as insufficient screening or excessive screening in some areas due to uneven vibration of the screen plate 212.

[0041] In one embodiment, the screening unit 21 further includes a collection hopper 216, which is located in front of the tray 211 along its tilt direction and is securely connected to the tray 211. The inlet end of the collection hopper 216 is located below the lower end of the sieve plate 212, and the outlet end of the collection hopper 216 is located above the mealworm collection box 3. Thus, the provision of the collection hopper 216 facilitates the collection of qualified mealworms screened from the lower end of the sieve plate 212 and directs them into the mealworm collection box 3, thereby preventing the mealworms from scattering, improving collection efficiency, and ensuring that the screened mealworms can be collected promptly and accurately for subsequent processing and utilization.

[0042] In some embodiments, a support frame is further included to support the high-positioned mealworm collecting box 3. Thus, the support frame provides stable support for the high-positioned mealworm collecting box.

[0043] Specifically, the support frame includes a support frame 1 51 and a support frame 2 52, which are arranged corresponding to the screening units of the second layer and the first layer respectively.

[0044] In some specific embodiments, the screening unit 21 further includes a guide plate 217, which is located at a low position inside the tray 211 and is securely connected to the tray 211. The guide plate 217 is used to guide the small-sized mealworms and insect feces screened out by the screen plate 212 to the discharge hole 2111.

[0045] In other specific embodiments, the sieve holes of the sieve plates 212 corresponding to the three screening units 21 gradually decrease from top to bottom.

[0046] In some embodiments, there are multiple air blowing pipes 214, which are symmetrically arranged on both sides of the tray 211 along the tilt direction. Thus, the symmetrical arrangement of the multiple air blowing pipes 214 can provide a more uniform and powerful airflow, and better accelerate the transfer of the screened mealworms and insect feces to the lower position of the tray 211.

[0047] In some embodiments, there are two vibration motors 213, which are symmetrically arranged on both sides of the tilt direction of the screen plate 212. Thus, the symmetrical arrangement of the two vibration motors 213 can provide the screen plate with a more balanced and stable vibration power, thereby improving the vibration effect and screening efficiency of the screen plate 212, and ensuring that the mealworms are evenly distributed on the screen plate 212 and fully screened.

[0048] The specific principles and usage of the device for separating large and small mealworms and their excrement provided in this embodiment are as follows:

[0049] 1. Preparation: Place the mealworm, large mealworm and excrement separation device on a flat surface, connect the power supply of the air pump, and ensure that the air pump can work normally and provide airflow to the air pipe 214.

[0050] 2. Start the device: Turn on the power of the air pump and the vibration motor 213 to start the device. The air pump starts to supply air to the air blowing pipe 214, and the air blowing pipe 214 blows out air; the vibration motor 213 drives the sieve plate 212 to start vibrating.

[0051] 3. Material feeding: The mixture of mealworms and insect feces to be separated is evenly fed onto the sieve plate 212 of the top screening unit. Note that the amount of material fed should not be too much to avoid clogging the sieve holes of the sieve plate 212 or affecting the screening effect.

[0052] 4. Screening Process: Driven by the vibration motor 213, the sieve plate 212 begins to vibrate, causing mealworms to move across it. Large mealworms remain on the sieve plate 212, moving downward as the plate vibrates, ultimately falling into the mealworm collection box 3. Small and medium-sized mealworms and their feces pass through the sieve holes in the sieve plate 212 and fall onto the tray. Airflow from the air pipe 214 quickly directs these small and medium-sized mealworms and their feces toward the discharge hole 2111 of the tray 211. From there, they fall onto the sieve plate 212 of the lower screening unit 21, and the screening process repeats.

[0053] 5. Collecting materials: After multi-stage screening, mealworms of different sizes fall into the corresponding mealworm collection boxes 3, and the excrement falls into the excrement collection box 4 at the bottom. Clean the materials in the collection box regularly to avoid overflow.

[0054] 6. Shutdown: After the separation work is completed, turn off the power of the vibration motor 213 and the air pump, stop the equipment operation, and clean the residual materials on the sieve plate 212, tray 211 and other components for next use.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
