Description

Technical Field

[0001] The utility model relates to the technical field of screening pupae, larvae and excrement of yellow mealworms, in particular to a screening device for pupae, larvae and excrement of yellow mealworms. Background Art

[0002] Yellow mealworms are the most ideal insects for artificial breeding. They are rich in protein, minerals and various amino acids. They have high edible and medicinal value and are also very important animal feed. Therefore, their economic value is very high and they are welcomed by farmers from all over the world. During the breeding process, since the growth rate of each mealworm is inconsistent, the mealworms must be screened and classified.

[0003] The utility model with the existing authorization announcement number CN210876285U discloses a separation device for screening yellow mealworm feces, insect skins, dead insects and live insects, including a bellows, a fan is installed at one end of the bellows, a feed inlet is provided at the top of the bellows located on one side of the fan, a feed hopper is installed at the feed inlet, a live insect discharge port is provided at the bottom of the bellows opposite to the feed inlet, a baffle is installed at the end of the live insect discharge port away from the fan, a dead insect discharge port is provided at the bottom of the bellows located outside the baffle, and an insect feces and insect skin discharge port is provided on the side of the bellows located outside the dead insect discharge port.

[0004] By adopting the above technical scheme, the utility model can separate living insects, dead insects, insect excrement and insect skins at one time, which greatly improves efficiency and reduces labor intensity.

[0026] See also Figure 1-4 The utility model discloses a screening device for pupae, larvae and excrement of mealworms, comprising a base frame 1, four springs 2 are fixedly connected to the upper surface of the base frame 1, a middle support rod 16 is arranged inside the base frame 1, the front and back sides of the middle support rod 16 are fixedly connected to the inner wall of the base frame 1, and the middle support rod 16 is fixed to the bottom of the base frame 1, which can reinforce the base frame 1 and play a stabilizing role.

[0027] The ends of the four springs 2 away from the base frame 1 are fixedly connected to the triangle irons 3, and the side of each group of triangle irons 3 close to each other is fixedly connected to the screen frame 4. The inner wall of the screen frame 4 is fixedly connected to the cover plate 10, and the cover plate 10 is located above the large screen 6. The cover plate 10 is used to suppress dust from being raised. When feeding, it comes into contact with the screen frame 4, which will generate vibration and thus generate dust.

[0028] The left and right sides of the screen frame 4 are fixedly connected to a vibration motor 5, the inner wall of the screen frame 4 is fixedly connected to a large screen 6, the inner wall of the screen frame 4 is fixedly connected to a small screen 7, the upper surface of the cover plate 10 is fixedly connected to a feed frame 11, the bottom surface of the feed frame 11 is fixedly connected to the upper surface of the screen frame 4, the feed frame 11 is used to add materials, and the long mouth design is compatible with the use of a feeding conveyor belt.

[0029] The small sieve 7 is located below the large sieve 6, the inner wall of the sieve frame 4 is fixedly connected with an insect feces guide plate 8, the front of the sieve frame 4 is fixedly connected with a pupa plate 12, the upper surface of the pupa plate 12 is fixedly connected with two enclosures 13, the back side of each enclosure 13 is fixedly connected to the front side of the sieve frame 4, the pupa plate 12 is used for guiding the screened pupae to facilitate storage, and the enclosure 13 is used for limiting to prevent the pupae from falling.

[0030] The insect feces guide plate 8 is located below the small sieve 7, the bottom surface of the sieve frame 4 is fixedly connected to the collecting frame 9, the back of the sieve frame 4 is fixedly connected to the larvae plate 14, the upper surface of the larvae plate 14 is fixedly connected to two baffles 15, the front side of each baffle 15 is fixedly connected to the back side of the sieve frame 4, the larvae plate 14 is used to guide the screened larvae to facilitate storage, and the baffles 15 are used to limit the position to prevent the larvae from falling.

[0031] A support rod 17 is arranged above the middle support rod 16, and the bottom surface of the support rod 17 is fixedly connected to the upper surface of the middle support rod 16. The support rod 17 is used to support the guide device, plays a role in supporting the tilt angle, and has the effect of unpowered automatic guidance.

[0032] The upper surface of the support rod 17 is fixedly connected with an insect excrement slide 18, which is located below the collecting frame 9. The insect excrement slide 18 is used to collect and guide insect excrement. The bottom of the device is used in conjunction with a collection box or a collection bag to conveniently collect insect excrement.

[0033] The working principle of the utility model is: first, two vibration motors 5 are electrically connected through a wire, and then the bottom frame 1 is used to support four springs 2. Since the springs 2 have the characteristic of rebounding after being compressed, the screen frame 4 is fixed in the air through four triangle irons 3. At this time, the power provided by the two vibration motors 5 can make the screen frame 4 vibrate as a whole. At this time, the material is put into the feed frame 11. The long and flat design of the feed frame 11 can be used in conjunction with a conveyor belt to reduce labor;

[0034] When the material enters the screen frame 4, it is first screened by the large screen 6. The size of the gap in the large screen 6 can be used to screen out the pupae. Since the pupae have shed their shells and grown legs, the screening grid size is slightly larger than that of the larvae that have not shed their shells. At this time, the material passes through the large screen 6 and only the larvae and insect feces are left. Then the small screen 7 can be used to screen out the larvae. Since the pupae have been screened out, the size of the small screen 7 only needs to be slightly larger than the insect feces to screen out the insect feces and only the larvae are left. Finally, the insect feces falls onto the insect feces guide plate 8 and enters the collection frame 9, and finally flows out through the insect feces slide 18. The pupae board 12 and the surrounding plate 13 are used to facilitate the collection of pupae, and the larvae board 14 and the baffle 15 are used to facilitate the collection of larvae. The screening device for pupae, larvae and insect feces of the yellow mealworm can quickly and accurately screen out pupae, larvae and insect feces. The force of gravity and vibration is used to prevent unclean screening. In addition, the workload will be greatly reduced in conjunction with the conveyor.
