Description

Technical Field

[0001] The present invention relates to a screening device for fresh insects and insect feces and sand with adjustable vibration sieve mode, and particularly to a support for a sorting device for fresh insects and insect feces and sand realized by a double-frame support device, a screening vibration of a sieve box realized by a vibration buffering device, a screening and collection of fresh insects and insect feces and sand realized by a screening and collection device, a power provided for vibration screening by a power driving device, and a regulation of the vibration mode of the sieve box driven by a vibration mode regulation device, belonging to the technical field of screening of fresh insects and insect feces and sand. Background Art

[0002] Hermetia illucens can process waste generated in human daily life, such as kitchen waste, etc. In order to make the obtained fresh insects and insect feces and sand conducive to subsequent commercial applications, it is necessary to separate the mixed materials of fresh insects and insect feces and sand. For example, manual separation has the problem of low work efficiency, and most current screening devices still have the problem of low screening efficiency in use: The main reasons are, firstly, the sieve mesh is easily blocked. After the sieve mesh is blocked, the insect feces and sand cannot be quickly screened and separated, and only by extending the working time of the device can the insect feces and sand be screened, which increases energy consumption to a certain extent and also affects the normal growth of fresh insects; secondly, the vibration sieve mode is single. Most screening devices mainly vibrate up and down for screening. Due to the small amplitude of the sieve vibration, when there is more insect feces and sand, the upper-layer insect feces and sand cannot be effectively screened away and still mix with the fresh insects, affecting the effective cultivation of fresh insects.

[0003] Therefore, in view of the problems such as low screening efficiency commonly existing in the use of existing screening devices for fresh insects and insect feces and sand, it is necessary to comprehensively consider the sieve vibration mode, anti-blocking, etc. of the screening device, and design a device that can efficiently screen fresh insects and insect feces and sand.

[0066] The present invention realizes the screening and collection of live insects and insect sand through the screening and collection device, that is, the mixture of live insects and insect sand is screened through the tapered holes 32 on the sieve box 6 in the screening and collection device, and the collected insect sand after screening is realized through the funnel 3 and the output pipe 2.

[0067] The present invention has plastic plates 31 with a transparent color on the four sides of the sieve box 6. Through this design, it is convenient to observe the screening situation of live insects and insect sand in the sieve box 6.

[0098] The guiding cylinder 33 and the ejector rod 35 adopt a threaded fit. The ejector post 34 moves freely in the guiding cylinder 33. A blind hole is provided in the ejector post 34, and the ejector rod 35 is inserted into the blind hole of the ejector post 34.

[0099] When the secondary pressing plate A24 and the secondary pressing plate D27 on the secondary cross plate 22 move upward, and the secondary pressing plate B25 and the secondary pressing plate C26 move downward, while the main pressing plate A19 and the main pressing plate D16 on the main cross plate 20 move upward, and the main pressing plate B18 and the main pressing plate C17 move downward, under the action of the power driving device, the inner support drives the sieve box 6 to vibrate up and down reciprocally; when the secondary pressing plate A24 and the secondary pressing plate D27 on the secondary cross plate 22 move downward, and the secondary pressing plate B25 and the secondary pressing plate C26 move upward, while the main pressing plate A19 and the main pressing plate D16 on the main cross plate 20 move upward, and the main pressing plate B18 and the main pressing plate C17 move downward, under the action of the power driving device, the inner support drives the sieve box 6 to vibrate back and forth reciprocally; when the secondary pressing plate A24 and the secondary pressing plate C26 on the secondary cross plate 22 move upward, and the secondary pressing plate B25 and the secondary pressing plate D27 move downward, while the main pressing plate A19 and the main pressing plate C17 on the main cross plate 20 move upward, and the main pressing plate B18 and the main pressing plate D16 move downward, under the action of the power driving device, the inner support drives the sieve box 6 to vibrate left and right reciprocally.

[0100] In the present invention, the vibration mode of the sieve box 6 is regulated by driving the vibration mode regulating device.

Through this design, the rotation of the ejector rod 35 drives the ejector pin 34 to move upward, and when the ejector rod 35 rotates reversely, the ejector pin 34 automatically moves downward under the action of gravity.
