Air supplementing and stirring device for biological fertilizer

Abstract

The invention discloses an air supplementing, fermenting and stirring device for biological fertilizer. The device comprises a stirring tank, a stirring rod is arranged in the stirring tank, a seal cover is arranged at the upper end of the seal cover, a first one-way air inlet valve is arranged on the seal cover, a first piston plate is connected to the inner wall of the stirring tank in a threaded mode, a through hole is formed in the upper portion of the stirring cavity, a stirring blade is located in the stirring cavity, the stirring rod is a spline shaft and is of a hollow structure, a spline sleeve is connected to the upper end of the stirring rod, and a stepping motor is fixedly connected to he upper end of the spline sleeve; the non-sleeved portion of the stirring rod is provided with a second one-way air inlet valve, and the portion, in the stirring cavity, of the stirring rod is provided with a one-way air outlet valve; an annular groove is formed in the portion, between the seal cover and the spline sleeve, a lantern ring is in clearance fit with the interior of the annular groove, a connecting rod is connected to the lantern ring, a water bag is attached to the outer wall of the stirring tank, a piston water pumper is connected to the upper end of the water bag and driven by the connecting rod, and a water band is communicated with a water tank. Compared with the prior art, the device has the advantages of being capable of conducting cooling and air supplementing on the biological fertilizer during stirring and lower in production cost.

Description

Technical field

[0001] The invention relates to the field of biological fertilizer production devices, in particular to a biological fertilizer supplemental gas fermentation stirring device. Background technique

[0002] In recent years, with the advancement of my country's modernized new countryside construction, my country's agriculture is developing rapidly in the direction of specialization, scale, and intensiveness. At the same time, the discharge of a large amount of livestock manure, crop stalks, edible fungus residue and other organic wastes has caused tremendous pressure on the ecological environment. On the other hand, with the rise of green agriculture, the status and role of biological fertilizers It has been placed in an important position in the field of agricultural bio-organic technology; biological fertilizer is commonly known as farm manure, which refers to a slow-acting fertilizer that contains a large amount of biological substances, animal and plant residues,...
