Description

Technical Field

[0001] The utility model relates to the technical field of bacterial fertilizer production, in particular to a stirring and turning device for bacterial fertilizer production. Background Art

[0002] After the white ginseng mushrooms have finished fruiting, the residue of the mushroom bag (including sawdust, cottonseed shells, etc.) is mixed with cow dung and other excrement for fermentation, which can effectively prepare biological fertilizer; in the preparation process of biological fertilizer, the degree of mixing of the residue of the mushroom bag and biological excrement directly determines the preparation efficiency and effect of the fertilizer. Chinese patent document CN218485752U discloses a fertilizer mixing device, which drives the first stirring blade to stir the raw materials in the cylinder by a driving motor, and at the same time uses the cooperation of two sets of first transmission wheels and transmission belts to drive the second stirring blade to mix and stir the raw materials in the cylinder, thereby improving the mixing efficiency in the production process of fertilizer; the fertilizer mixed by stirring is improved through the material guide slope to improve the efficiency of material discharge, and the unmixed fertilizer can be isolated in the interior of the cylinder through the screen to continue mixing and stirring, and the fully mixed fertilizer falls into the discharge pipe through the discharge port, and the fertilizer is then transported to the collection box by the discharge pipe for centralized collection, so that the fully mixed fertilizer can be taken out later. However, during the stirring process of the mixing device, the bacterial fertilizer raw materials are easily deposited at the bottom of the cylinder due to gravity. The above mixing device lacks a material turning mechanism for the bottom raw materials, that is, horizontal stirring and mixing, which directly affects the mixing uniformity and mixing effect of the bottom raw materials; at the same time, during the stirring and mixing process of the bacterial fertilizer raw materials, the raw materials are easy to remain and adhere to the inner wall of the cylinder, which will cause problems such as difficulty in cleaning and uneven mixing in the short term, and will cause problems such as mildew, aging, and odor on the inner wall of the cylinder in the long term.

[0023] A visual window is provided on one side wall of the mixing cylinder 100 to facilitate observation of the mixing conditions inside the mixing cylinder.

[0024] Working principle:

[0025] When in use, firstly pull out the sealing plug of the feed pipe 101 and the sealing plug of the discharge port 102, and then pour the mixed raw materials into the feed pipe 101 respectively. Afterwards, the sealing plug of the feed pipe 101 is closed, and the rotation of the rotating rod 11 is started by the driving motor 110. The rotating rod 11 drives the stirring rod 30, the turning mechanism and the "L"-shaped scraper 40 to rotate around the central axis of the rotating rod 11 respectively: the stirring rod 30 rotates to complete the horizontal mixing of the materials in the mixing drum 100; during the axial rotation of the turning mechanism around the rotating rod 11, due to the engagement between the bevel gear 23 and the gear ring 104, the bevel gear 23 rotates, driving the guide rod 21 to rotate, and then driving the turning rod 24 to rotate around the central axis of the guide rod 21, and the connecting soft belt 25 provided on the turning rod 24 is used to turn the raw materials at the bottom of the mixing drum 100, and the gap between the connecting soft belts 25 is used to shake off the raw materials after turning, thereby realizing longitudinal mixing of the raw materials after turning; the "L"-shaped scraper 40 rotates to prevent the raw materials from adhering to the inner wall and bottom surface of the mixing drum 100, so as to facilitate uniform mixing and avoid difficulty in cleaning after material deposition. After the stirring and mixing is completed, the sealing plug of the discharge port 102 is opened to complete the discharge. During the discharge process, the low-speed rotation of the rotating rod 11 is ensured to effectively avoid the adhesion of the raw materials to the inner wall of the mixing barrel 100 and to improve the discharge efficiency.
