Extruding device for producing organic fertilizers

Abstract

The invention discloses an extruding device for producing organic fertilizers. The extruding device comprises an upper pressing plate; a lower pressing plate is arranged below the upper pressing plate; the upper pressing plate is connected with a first rack; the first rack is engaged with a first gear; the first gear is engaged with a second rack; the lower pressing plate is connected with a third rack; the third rack is engaged with a second gear; the second gear is engaged with a fourth rack; the second rack and the fourth rack are both connected with first springs; the second rack and the fourth rack are both provided with wedge surfaces; the two wedge surfaces are butted against with the same turntable; the upper pressing plate and the lower pressing plate are slidingly connected with a feed hopper; the feed hopper is provided with a feed port and a discharge port; the feed hopper is communicated with a push pipe; a push plate is slidingly connected into the push pipe; the push plate is connected with a push rod; a swing rod is arranged on the left side of the push rod, and is connected with a spring; the bottom of the swing rod is butted against a cam; the swing rod is slidingly connected with a slide block; and the push rod is hinged to the slide block. The extruding device is high in crushing efficiency, and solves the problem of low grinding efficiency.

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 breeding scale of farms in our country, centralized 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 sustai...

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
