Plastic manure filling bag breaking machine

Abstract

The invention relates to a machine for puncturing and tearing a manure filling bag, which comprises a pair of spiked rotary drums. The flat spikes on the spiked rotary drums are stricken into the manure filling bag, the two flat spikes stricken into the manure filling bag produce relative displacement to tear off and break the plastic bag by means of the great rotation speed difference between the two rotary drums, and manure in the bag is thrown into a manure collecting bin to be used as maggot fodder. The machine promotes the connection between a dry close stool and a maggot raising device and is a key device drawing back human manure from a pollution source and using as fodder in an artificially optimized protein cycle.

Description

technical field [0001] The present invention uses a pair of barbed rollers with flat thorns to roll relative to each other at different rotational speeds to puncture the fecal plastic bags, and the two sets of flat thorns pierced into the plastic bags move relatively due to the different rotational speeds between the rollers. It is a kind of bag-breaking machine that pulls and breaks the plastic bag into several pieces, so that the feces and urine in the bag can be thrown out and leaked out of the machine to be collected as maggot feed. Background technique [0002] The development of chemical fertilizers quickly met the needs of agricultural production. As a result, urban human excrement has also changed from a sought-after agricultural material to a waste that is rejected by the countryside. On the one hand, this drastic change has promoted the development of urban sanitation: after the urban waste lost its way to support agriculture, it led to the rapid elimination of woo...

Problems solved by technology

Fly maggots eat fungi in the feces for a living, and the bacteria multiply extremely fast at a suitable temperature. After hundreds of millions of years of evolution, the fly maggots that eat fungi have also adapted to the rapid growth of bacterial proteins. Their growth speed is as fast as in the animal world. It is also second to none. Raising maggots is a fast and efficient method of protein circulation. It can kill two birds with one stone when protein is lacking and fecal pollution is difficult to control. At present, urban manure can be collected using dry toilets ( The patent application number is Z00710007172.1) to replace the flush toilet, pack the excrement and urine in a plastic film bag, carry it to the garbage station and put it in a special trash can, and then transport it to the maggot raising factory. The maggot raising factory is equipped with automatic maggot raising equipment (As the patent application number is 200820161504.1 " assembly line equipment for raising maggots with feces and urine "), naturally also to tear the plastic bags of feces and urine to separate the excrement and urine from the plastic bag so that the excrement and urine can be spread on the maggot culture belt, The maggot factory has to deal with tons or dozens of tons of feces and urine every day, and each ton of feces and urine is packaged in thousands of plastic film bags. Naturally, it cannot be completed by hand tools. It must be completed by special bag breaking facilities. When there is no competent existing equipment, it is necessary to design and manufacture special bag breaking equipment
