Extrusion device for fertilizer manufacturing

Abstract

The invention discloses an extrusion device for fertilizer manufacturing. The extrusion device comprises a machine frame, a feed hopper is arranged on the machine frame, an upper pressing plate and a lower pressing plate are connected in the feed hopper in a sliding mode, the upper pressing plate is connected to an upper connecting rod with the top being a wedge surface, the upper connecting rod is connected to an air cylinder and abuts against a first idler wheel, the first idler wheel is connected to a rack, a spring is connected to the side, away from the first idler wheel, of the rack, the rack is meshed with a gear, the gear is connected to a roller, a rope winds around the roller, the lower pressing plate is connected to a lower connecting rod, and the free end of the rope winds around the lower connecting rod; a feed hole is formed in one side of the feed hopper, the bottom of the feed hopper is communicated with a pushing pipe, a discharge hole is formed in the wall of the side, opposite to the pushing pipe, of the feed hopper, a pushing plate is connected in the pushing pipe in a sliding mode and is connected to a pushing rod, and the pushing rod abuts against a cam and is connected to a second spring. The extrusion device for fertilizer manufacturing can improve the crushing efficiency and solve the problem that existing grinding devices are low in grinding efficiency.

Description

Technical field [0001] The invention relates to the field of extrusion devices, in particular to an extrusion device for fertilizer production. Background technique [0002] Pig manure is a large amount of feces excreted by pigs in the process of raising pigs. It is a kind of crude fiber, which is mixed with a large amount of urine and mucus. Pig manure is a kind of poultry manure that is not easy to dry. With the continuous expansion of the scale of farms in my country, intensive farming brings a large amount of pig manure centralized, which is difficult to deal with when piled together. Long-term storage not only attracts mosquitoes and flies, but also causes great pollution to the surrounding environment and groundwater sources. If the problem of pig manure is not environmentally friendly, it will not only cause increasingly serious environmental pollution, but also cause the sustainable development of farms. Serious impact. How to effectively treat pig manure and effectivel...

AI Technical Summary

Problems solved by technology

[0004] In the process of making pig manure into fertilizer, it is necessary to process the pig manure through dehydration, drying, grinding, mixing, molding and other steps. In the grinding step of the prior art, people use the dried pig manure to It is directly fed into the grinding device for grinding, but because there will be a large number of coarse particles in the pig manure, so if it is directly ground, a large amount of pig manure will be ground unevenly, and the pig manure needs to be ground again many times. Make the pig manure grind evenly, increase the grinding time and reduce the grinding efficiency
