Technical Field

The invention relates to the technical field of organic fertilizer processing, in particular to a stirrer for organic fertilizer.

Background

The organic fertilizer is prepared by fermenting and decomposing various straws, fallen leaves, green grass, kitchen garbage, animal and plant residues and human and animal excrement which are used as raw materials with enzyme, and stirring is an essential process in the production process of the organic fertilizer, and directly influences the quality stability of the fertilizer.

The conventional stirring device mainly comprises a container with an open top, a stirring shaft arranged in the container, and a driving mechanism fixedly arranged outside the container. Most of the area of the bottom of the container is attached with a heating unit to heat the interior of the container; the driving mechanism drives the stirring shaft to rotate by the driving of a motor; the outer ring surface of the stirring shaft extends with a plurality of stirring rods which are different in direction and branch, and each stirring rod moves in the container along with the rotation of the stirring shaft so as to stir various raw materials in the container and uniformly mix the various raw materials. After the stirring is completed, the container is turned over, so that the open top surface of the container is inclined downwards to pull out the mixed material.

The existing stirring device has the following defects:

1. the heating unit is attached to the container for heating, so that the temperature in the container is slowly raised due to low heat conduction efficiency, long time is needed for stirring, and the processing time is long; in addition, waste gas generated by heating in the container is directly discharged, so that the environment is polluted;

2. the container has no structure corresponding to thermal expansion, the container can expand and deform due to the thermal expansion effect in the long-time heat conduction process of the container, the end part of the container can press the bearing for connecting the container and the stirring shaft, and the bearing can generate larger noise in the stirring process, so that the service life of the bearing is reduced;

3. the top of the container is downward by turning the container, so that an operator can pull out the mixed materials from the stirring rods, and the mixed materials are evenly accumulated in the container, so that the operator needs to greatly stretch the two hands into the space between the stirring rods to pull out the mixed materials, the efficiency is poor, and the danger caused by carelessly touching the stirring rods is increased.

In view of the above-mentioned defects, the present designer is actively making research and innovation to create a new mixer for organic fertilizer, so that the mixer has more industrial utility value.
