Description

Technical Field

[0001] The utility model relates to the technical field of biological fertilizer production devices, in particular to a biological fertilizer air replenishing and stirring device. Background Art

[0002] Biofertilizer, commonly known as farmyard manure, is made by fermenting, mixing and stirring various substances including animal and plant residues, excrement and other substances. Generally, the most commonly used device in the production of biofertilizer is the biofertilizer stirring device. Biofertilizer needs to maintain good aerobic bacteria during fermentation. However, the existing oxygen and biofertilizer have low contact and gas recycling cannot be used.

[0003] In order to solve such problems, Chinese patent CN218174845U, a bio-fertilizer air supply and stirring device, points out that the driving motor drives the air supply shaft to rotate to the right through the driving gear and the driven gear, and the air supply shaft drives the fertilizer lifting spiral blade to rotate. At this time, the fertilizer lifting spiral blade will lift the fertilizer inside the bio-fertilizer fermentation box upward and stir it.

[0004] Secondly, Chinese patent CN217887777U, a biofertilizer aeration stirring device, points out that the operation of the electric slider can drive the entire fermentation tank to move back and forth along the guide rail, and the operation of the motor can drive the vertical stirring shaft and the first stirring paddle and the active bevel gear thereon to rotate synchronously. Under the meshing transmission of the two driven bevel gears and the active bevel gear, the rotation of the active bevel gear can also drive the two vertical stirring shafts and the first stirring paddles on both to rotate, and the rotation directions of the two vertical stirring shafts are opposite, so that the rotating first stirring paddle and the second stirring paddle can cooperate with the fermentation tank that moves left and right as a whole to achieve multi-axis and multi-directional effective stirring of the material, greatly reducing the stirring dead angle, and the square stirring frame of the first stirring paddle, the vertical stirring rod and the horizontal stirring rod can greatly enhance the stirring strength and stirring effect of the first stirring paddle, and the oblique stirring rod of the second stirring paddle can greatly enhance the stirring strength and stirring effect of the second stirring paddle, so that the multi-axis and multi-directional stirring of the material is more efficient and effective, and the materials can be mixed more evenly and completely with each other.

[0005] In the above two documents, the patent CN218174845U, although the biofertilizer aeration stirring device can achieve a higher contact surface between oxygen and biofertilizer, the internal gas is directly discharged and not recycled. Secondly, the stirring efficiency of the biofertilizer in the device is low, and when the biofertilizer is pressed on the lifting stirring and gas transmission shaft structure at the same time, its power consumption is large. Secondly, the patent CN217887777U, although the biofertilizer aeration stirring device can effectively make oxygen contact with biofertilizer, according to the attached drawings of the document, it can be seen that the structure is relatively cumbersome and complicated, and it is more laborious during the stirring process.

[0006] Therefore, in order to improve the mixing of biofertilizer and reduce the mixing energy consumption, and also enable the gas entering the mixing tank to be reused, a biofertilizer gas supplement mixing device is proposed. Utility Model Content
