Black soldier fly larvae sorting machine based on biological characteristics

Abstract

This invention relates to the field of black soldier fly farming technology, and in particular to a black soldier fly sorting machine based on biological characteristics. It includes a main frame, a feed hopper mounted on the top left side of the main frame, a spiral feeder mounted at the bottom of the feed hopper, a collection hopper mounted on the top of the main frame, a separating conveyor belt fixedly mounted inside the collection hopper, a longitudinal conveyor belt below the collection hopper, and a transverse conveyor belt at the end of the longitudinal conveyor belt. Several fans are mounted above the collection hopper via a bracket, and lamps are mounted below the fans via a bracket. This application uses a spiral feeder for feeding, thus reducing the likelihood of clogging at the feed inlet and improving feeding efficiency. The arrangement of fans and lamps, based on the black soldier fly's tendency to seek advantage and avoid harm, enables the sorting of black soldier flies and their excrement, improving sorting efficiency. Furthermore, the design of the plug and umbrella-shaped baffle further reduces the risk of clogging.

Description

Technical Field

[0001] This invention relates to the field of black soldier fly farming technology, and in particular to a black soldier fly sorting machine based on biological characteristics. Background Technology

[0002] Black soldier flies, saprophytic insects of the family Stray Fly, feed on livestock manure and household waste, producing high-value animal protein feed. Due to their rapid reproduction, large biomass, wide diet, high absorption and conversion rate, ease of management, low feeding costs, and good palatability, they are widely used for resource utilization. Currently, they are extensively used in the treatment of chicken manure, pig manure, and kitchen waste.

[0003] In the sorting process of black soldier fly farming, the main task is to separate the excrement and black soldier flies. The main problems with traditional sorting machines are: (1) low sorting efficiency; (2) during the feeding process, the feed inlet is easily blocked due to the stickiness of the raw materials, which requires manual handling; (3) in addition to the inability to sort continuously and low efficiency, the sorting holes are also easily blocked and difficult to clean, resulting in low sorting efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a black soldier fly sorting machine based on biological characteristics with high sorting efficiency.

[0005] The technical solution of this invention is as follows: a black soldier fly sorting machine based on biological characteristics, comprising a main frame, a feed hopper installed on the top left side of the main frame, a spiral feeder installed at the bottom of the feed hopper, a collection hopper installed on the top of the main frame, a separating belt conveyor fixedly installed inside the collection hopper, a longitudinal belt conveyor arranged below the collection hopper, a transverse belt conveyor installed at the end of the longitudinal belt conveyor, and several fans mounted above the collection hopper via brackets, with brackets below the fans... A lamp tube is installed, and below the lamp tube is a cricket-splitting belt conveyor. Several plugs are evenly distributed on the frame of the cricket-splitting belt conveyor. The bottom of each plug has a threaded hole, and a screw is threaded into the threaded hole. The screw passes through the frame and is installed in the threaded hole. There are gaps between the two sides of the plug and the cricket-splitting belt of the cricket-splitting belt conveyor. An umbrella-shaped baffle is installed on the top of the plug. The cross-section of the umbrella-shaped baffle is trapezoidal. A trapezoidal groove is installed below the plug. A rectangular groove is connected to the bottom of the trapezoidal groove. During sorting, the lamps and fans are turned on. The fan blows the heat emitted by the lamps downwards. As a resource insect, black soldier flies are afraid of white light and heat (above 45°C) during their larval stage. The heat emitted makes the black soldier flies to be sorted uncomfortable, causing them to wriggle continuously. To avoid this, they will try to find holes to burrow into. Because there is a gap between the outer periphery of the plug and the insect-splitting conveyor belt, the wriggling black soldier flies will crawl into the trapezoidal trough through the gap and then fall into the transverse conveyor belt of the longitudinal belt conveyor through the rectangular trough. During the burrowing process, the feces and other impurities attached to the black soldier flies will be scraped off by the umbrella-shaped baffle and left on the insect-splitting conveyor belt, thus performing sorting. The feces and other impurities will continue to be conveyed forward with the insect-splitting conveyor belt and finally fall into the feces collection device. The sorted black soldier flies will continue to be conveyed forward with the longitudinal belt conveyor and fall into the transverse belt conveyor at the end of the longitudinal belt conveyor to be conveyed into the black soldier fly collection device.

[0006] Furthermore, the top of the hopper is equipped with multiple openable and closable heat-insulating covers for heat preservation inside the hopper.

[0007] Furthermore, the hopper is also equipped with a material end plate and a material hopper tie plate, which are made of galvanized sheet. A rubber sealing strip is bolted to the bottom of the hopper, and the rubber sealing strip is specifically made of silicone rubber.

[0008] Furthermore, a baffle plate is installed between the outlet end of the spiral feeder and the insect-dividing belt conveyor, and the baffle plate is made of galvanized sheet.

[0009] Furthermore, the insect-splitting conveyor belt is provided with multiple adjacent insect-splitting conveyor belts, which are separated by spacers set at the head and tail ends of the conveyor.

[0010] Furthermore, the lamp tube can be an LED strip light assembly: ultra-bright white light, energy-saving and reliable, with a color temperature of up to 6500-7000K.

[0011] The beneficial effects of this invention are as follows: 1. This application uses a spiral feeder for feeding, which makes it less likely to cause blockage at the feed inlet, thereby improving feeding efficiency; 2. By setting up a fan and lamp tube, based on their biological characteristics of seeking advantage and avoiding harm, black soldier flies and their excrement can be separated, improving sorting efficiency; 3. Continuous sorting can be performed, and the setting of the plug and umbrella-shaped baffle makes it less likely to cause blockage. Attached Figure Description

[0017] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings:

[0018] like Figure 1-4As shown, a black soldier fly sorting machine based on biological characteristics includes a main frame 1. A feed hopper 2 is installed on the top left side of the main frame 1, and a spiral feeder 3 is installed at the bottom of the feed hopper 2. A collection hopper 4 is installed on the top of the main frame 1. A separating belt conveyor 5 is fixedly installed inside the collection hopper 4. A longitudinal belt conveyor 6 is arranged below the collection hopper 4, and a transverse belt conveyor 7 is installed at the end of the longitudinal belt conveyor 6. Several fans 8 are installed inside the collection hopper 4 via brackets, and lamp tubes 9 are installed below the fans 8 via brackets. Below 9 is the insect-splitting belt conveyor 5. Several plugs 10 are evenly distributed on the frame of the insect-splitting belt conveyor 5. The bottom of the plug 10 is provided with a threaded hole, and a screw 11 is threaded into the threaded hole. The screw 11 passes through the frame and is installed in the threaded hole. There are gaps between the two sides of the plug 10 and the insect-splitting conveyor belt of the insect-splitting belt conveyor 5. The top of the plug 10 is provided with an umbrella-shaped baffle 12. The cross-section of the umbrella-shaped baffle 12 is trapezoidal. The bottom of the plug 10 is provided with a trapezoidal groove 13, and the bottom of the trapezoidal groove 13 is connected to a rectangular groove 14.

[0019] The top of the hopper 4 is equipped with multiple openable and closable heat-insulating covers 15 for heat preservation inside the hopper 4.

[0020] The hopper 4 is also equipped with a material block plate 16 and a material hopper tie plate 17. The material block plate 16 and the material hopper tie plate 17 are galvanized plates. The bottom of the hopper 4 is equipped with a rubber sealing strip 18 by bolts. The rubber sealing strip 18 is specifically a silicone rubber plate.

[0021] A baffle plate 19 is installed between the outlet end of the spiral feeder 3 and the insect-separating belt conveyor 5. The baffle plate 19 is made of galvanized sheet.

[0022] The insect-splitting conveyor belt is provided with multiple belts, and adjacent insect-splitting conveyor belts are separated by spacers set at the head and tail ends of the conveyor.

[0023] The lamp tube 9 can be an LED strip light assembly: ultra-bright white light, energy-saving and reliable, with a color temperature of up to 6500-7000K.

[0024] During sorting, the lamps and fans are turned on. The fan blows the heat emitted by the lamps downwards. As a resource insect, black soldier flies are afraid of white light and heat (above 45°C) during their larval stage. The heat emitted makes the black soldier flies to be sorted uncomfortable, causing them to wriggle continuously. To avoid this, they will try to find holes to burrow into. Because there are gaps between the two sides of the plug and the insect-splitting conveyor belt, the wriggling black soldier flies will crawl into the trapezoidal trough through the gaps and then fall into the transverse conveyor belt of the longitudinal belt conveyor through the rectangular trough. During the burrowing process, the feces and other impurities attached to the black soldier flies are scraped off by the umbrella-shaped baffle and left on the insect-splitting conveyor belt, thus performing sorting. The feces and other impurities continue to be conveyed forward with the insect-splitting conveyor belt and finally fall into the feces collection device. The sorted black soldier flies continue to be conveyed forward with the longitudinal belt conveyor and fall into the transverse belt conveyor at the end of the longitudinal belt conveyor to be conveyed into the black soldier fly collection device.

[0025] The embodiments and descriptions above are merely illustrative of the principles and preferred embodiments of the present invention. Various changes and modifications may be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
