Mixing device for preparing amino acid organic fertilizer

Abstract

The invention discloses a mixing device for preparing an amino acid organic fertilizer. The device includes a bottom plate, wherein output shafts of two electric hydraulic cylinders are fixedly connected with the two sides of the bottom end of a top plate correspondingly. An output shaft of a stirring motor penetrates through the top plate and is fixedly connected with a stirring shaft in a tank cover; a scraping plate is mounted on one side of each of a plurality of buffer devices; the inner wall of a heating shell is fixedly sleeved with the outer wall of the tank body. According to the disclosed mixing device, the plurality of scraping plates connected with the buffer devices are arranged on the two sides of the stirring shaft; the scraping plates can be in contact with the inner wall of the tank body to clean raw materials adhered to the inner wall surface of the tank body and guarantee uniform mixing, meanwhile, when the tank body is placed obliquely, the buffer devices provide buffer force for the scraping plates, hard contact between scrapers and the inner wall of the tank body is avoided, the scrapers and the tank body are effectively protected, and meanwhile, a stirring bottom block is arranged to mix the raw materials at the bottom of the tank body.

Description

technical field [0001] The invention relates to a mixing device, in particular to a mixing device for preparing amino acid organic fertilizer, which belongs to the technical field of organic fertilizer preparation. Background technique [0002] Organic fertilizers are mainly derived from animals and plants. They are processed from animal and plant waste, excrement, and residues. They are rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and nitrogen, phosphorus, and potassium. The nutrient elements can not only provide comprehensive nutrition for crops, but also have long fertilizer effect, can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity, and are the main nutrients for green food production. [0003] In the process of producing organic fertilizer, it is necessary to mix crushed crop stalks, human and animal manure, animal residues,...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of mixing device for preparing amino acid organic fertilizer, to solve the existing mixing device proposed in the above background technology, only the motor drives the stirring shaft to stir, the mixing is uneven, and some raw materials are easy to stick to the stirring tank The inner wall of the tank, and the connected scraper on the stirring shaft can effectively clean the inner wall, but because the scraper and the stirring shaft are fixedly connected, when the tank is placed unstable, the scraper directly contacts the inner wall of the tank, The problem of causing damage to both the inner wall of the tank and the scraper
