Description

Device convenient to black soldier fly handles chicken manure Technical Field The invention relates to the technical field of agricultural cultivation, in particular to a device convenient for treating chicken manure by hermetia illucens. Background The chicken manure is used as main waste generated in the livestock and poultry breeding process, has complex components and is rich in organic matters, and if the chicken manure is improperly treated, the chicken manure is very easy to become a hotbed for breeding pathogenic microorganisms. These microorganisms include pathogenic bacteria such as escherichia coli, salmonella, staphylococcus aureus and the like, and parasitic ova such as ascarid ova and coccidian ova, which can not only be transmitted through air, water sources or soil to cause zoonosis, but also cause environmental problems such as eutrophication of water bodies and soil degradation, so how to efficiently and safely treat chicken manure, and blocking the transmission chain of pathogenic microorganisms becomes a key challenge for recycling agricultural wastes. The black soldier fly is taken as a saprophytic insect, and the unique biological characteristics of the black soldier fly enable the black soldier fly to show remarkable control advantages of pathogenic microorganisms when the chicken manure is treated, so that an innovative scheme is provided for solving the problem. The existing device for treating chicken manure by hermetia illucens mainly comprises a chicken manure pretreatment unit, a hermetia illucens culture unit and a worm manure separation unit. The working principle of the method is that chicken manure is simply crushed and subjected to humidity adjustment and then is sent to a culture unit, black soldier fly larvae eat the chicken manure and are converted into insect protein, and the residual insect manure is collected through a separation unit. The device realizes chicken manure reduction through the rapid biodegradation of the black soldier flies (the treatment period can be shortened to 7-15 days), but the pretreatment unit has the defects that the uniformity of the chicken manure particles is difficult to ensure by simple crushing, and pathogens in the large chicken manure particles are difficult to completely remove when the large chicken manure particles are heated, so that part of the chicken manure cannot be effectively treated, the whole reduction effect is affected, and the growth of the black soldier flies is not facilitated. Disclosure of Invention The invention aims to provide a device for treating chicken manure by using hermetia illucens, which has the effects of simultaneously realizing stirring, crushing, heating and falling of the chicken manure, and the chicken manure pretreated by heating, crushing and stirring so that pathogens are killed efficiently, and meanwhile, the physical state, the temperature and other conditions of the device are suitable for growth of the hermetia illucens. The technical aim of the invention is achieved by the following technical scheme that the device for treating chicken manure by using black soldier flies conveniently comprises a culture box, wherein a pretreatment mechanism is arranged at the inner top of the culture box, the pretreatment mechanism comprises a perforated pretreatment box fixedly connected to the culture box, a heating mechanism and a crushing stirring assembly are arranged in the perforated pretreatment box, the crushing stirring assembly comprises a stirring piece arranged at the upper part of the perforated pretreatment box, a driver and a crushing piece arranged at the lower part, a driving shaft of the driver is fixedly connected to the top end of the stirring piece, the bottom end of the stirring piece is connected to the top of the crushing piece through a transmission mechanism, the transmission mechanism comprises a plurality of grooves formed in the side walls of the crushing piece, a first transmission plate rotationally connected to the inner parts of the grooves, and a plurality of second transmission plates fixedly connected to the outer surfaces of the stirring piece, when the driver drives the stirring piece to rotate clockwise, the second transmission plates are separated from the second transmission plates, and only the driver drives the stirring piece to rotate chicken manure anticlockwise, and when the driver drives the first transmission plates and the second transmission plates rotate, and the second transmission plates are mutually meshed with the first transmission plates. The electric heating element (PTC constant temperature heating pipe) of heating mechanism inserts 220V power, set for heating temperature and be 75 to 80, after the circular telegram, PTC constant temperature heating pipe produces the heat, distribute heat to foraminiferous pretreatment incasement through the mode of heat transfer, carry out heating treatment to the chicken manure in the case, realize the transient in
