Extruding device for producing organic fertilizers

Abstract

The invention discloses an extruding device for producing organic fertilizers. The extruding device comprises a frame; a feed hopper is arranged on the frame; an upper pressing plate and a lower pressing plate are slidingly connected into the feed hopper; the upper pressing plate is connected with an upper connecting rod with the top as a wedge surface; the upper connecting rod is connected with a cylinder, and is butted against a roller; the roller is connected with a rack; the right side of the rack is connected with a first spring; the rack is engaged with a gear; the gear is connected with a drum; the drum is wound with a rope; the lower pressing plate is connected with a lower connecting rod; the rope is wound on the lower connecting rod; a feed port is formed in one side of the feed hopper; the bottom of the feed hopper is communicated with a push pipe; a discharge port is formed in the wall of the feed hopper on one opposite side of the push pipe; a push plate is slidingly connected into the push pipe, and is connected with a push rod; a swing rod is arranged on the left side of the push rod, and is connected with the spring; a cam is butted against the bottom of the swing rod; and the swing rod is slidingly connected with a slide block. The invention provides an extruding device with high 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 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 development of...

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
