Embodiment 1

[0024] Such as figure 1 As shown, the multi-layer fly maggot breeding device described in the present embodiment includes three layers of breeding conveyor belts, the conveyor belt width is 1m, and the length is 20m, and the distance between the breeding conveyor belt layer and the layer is 60cm. There are four partitions 110 on the whole conveyer belt, and the conveyer belt is divided into four areas, wherein two large areas are breeding bed areas 201, two small areas are connecting areas 202, and the breeding area is a semi-enclosed space with edges of PVC skirt baffle plate 112, its height is 10cm; The bottom of the left end of the top layer and the bottom cultivation conveyor belt, the bottom of the right end of the middle layer cultivation conveyor belt are all fixed with an inclined feeding chute, and the lower feeding chute 102 is provided with an inclined feeding chute 104 , the inclination angles of the feeding chute and the feeding chute are both 120°, a roller 103 i...

Embodiment 2

[0034] Such as figure 1 As shown, the present embodiment adopts three layers of fly maggot cultivating device, and the general structure is the same as in embodiment 1, but the conveyor belt width used is 1.5m, and the length is 35m, and the interval between layers of the breeding area is 50cm. The height of the PVC skirt baffle is 10cm; the inclination angles of the feeding chute and the returning chute are both 110°. The organic waste used in this case is fresh pig manure with a water content of 80%, without any other auxiliary materials. The breeding time is autumn, and the breeding cycle is 6 days. The retractable infrared lamp 105 is located above the breeding area; the sprinkler 106 is located below the infrared lamp, but it is not opened in this case.

[0035] Fresh feces and young fly maggots are first dropped on the first layer. Next, after 2 days of fly maggot growth and material transformation, the pile in the first layer has been relatively stable. Turn on the ...

Abstract

The invention provides a multi-layer fly larva breeding device and method. The device comprises a plurality of breeding conveyor belts driven by motors. A discharge tank is fixed below each breeding conveyor belt. Electric brushes are arranged on the tops of the discharge tanks. Material return tanks are arranged below the discharge tanks. Wheels are arranged between the lower ends of the discharge tanks and the top ends of the material return tanks. A heater is arranged above each breeding conveyor belt. Water sprinklers are arranged below the heaters. The device further comprises an electronic controller which controls the motors, the heaters, the water sprinklers and the electric brushes to be turned on and turned off. When breeding is conducted through the device, breeding areas correspond to different fly larva breeding periods, and pile body alternation and stack turning and stirring between the layers are achieved through the linked inclined groove type technology of the discharge tanks, the wheels, the material return tanks and other facilities. By means of the device and the method, places occupied by fly larva breeding are greatly saved, the utilization rate of materials is increased through automatic stack turning between the layers, and continuous use and circulating breeding can be achieved.

Description

technical field [0001] The invention relates to the field of fly maggot culture, in particular to a multi-layer fly maggot culture device and a culture method. Background technique [0002] As one of the typical technologies of worm bioreactors, fly maggot breeding technology has the technical advantages of "high efficiency, high value and environmental friendliness" in the treatment and recycling of organic waste such as livestock manure, meal waste, food processing residues, etc. It has increasingly received widespread attention from all walks of life. [0003] Due to the characteristics of low technical difficulty, low construction cost, and simple breeding management, the ground flat farming technology is currently the most common technical mode for raising fly maggots with organic waste. However, this type of technical model has the following deficiencies: 1) the organic waste for the growth and transformation of fly maggots is laid on the single ground surface of the ...
