Extruding device for producing organic fertilizer

Abstract

The invention discloses an extruding device for producing organic fertilizer. The extruding device comprises a machine frame. A feeding hopper is arranged on the machine frame, an upper pressure plate and a lower pressure plate are connected into the feeding hopper in a slidable mode. An upper connection rod with the top being a wedge face is connected to the upper pressure plate and is connected with a first air cylinder. A rolling wheel abuts against the upper connection rod and is connected with a rack. A spring is connected with one side, away from the rolling wheel, of the rack which is engaged with a gear. The gear is connected with a roller, a rope is wound around the roller, a lower connection rod is connected to the lower pressure plate, and the free end of the rope is wound around the lower connection rod. A feeding opening is formed in one side of the feeding hopper, the bottom of the feeding hopper is communicated with a pushing tube, a discharging opening is formed in the wall of the feeding hopper in one side opposite to the pushing tube, a pushing plate is connected into the pushing tube in a slidable mode, a pushing rod is connected with the pushing plate, and a second air cylinder is connected with one side, away from the pushing plate, of the pushing rod. The extruding device for producing the organic fertilizer can improve the crushing efficiency, so that the problem of low grinding efficiency of existing grinding devices is solved.

Description

technical field [0001] The invention relates to the field of extruding devices, in particular to an extruding device for making organic fertilizer. 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 mixed with a lot of urine and mucus. Pig manure is a kind of poultry and livestock manure that is not easy to dry. With the continuous expansion of the scale of farms in my country, intensive farming has brought about the concentration of a large amount of pig manure, and it is difficult to deal with a large amount of pig manure piled up together. Long-term placement not only attracts mosquitoes and flies, but also causes great pollution to the surrounding environment and groundwater sources. If the pig manure problem is not environmentally friendly, not only will the pollution of the environment become increasingly serious, but it will also cause serious damage to the sustainable develo...

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
