Closed premixing device for biological feed production

Abstract

The invention discloses a closed premixing device for biological feed production. The device comprises an outer box and a premixing box; a feeding bin is arranged at the middle point of the top of theouter box; a second motor is arranged on the outer box; the second motor penetrates through the outer box body and is connected with a rotating shaft; a plurality of stirring rods are arranged on therotating shaft and are arranged on the rotating shaft at equal intervals; the stirring rod is provided with a protruding part protruding backwards in the rotating direction, and the width of the protruding part is equal to the diameter of the stirring rod; wherein the plurality of stirring rods are spirally arranged on the rotating shaft; an included angle of 30-60 degrees is formed between the axis of the stirring rods and the axis direction of the rotating shaft; a first motor is started to drive a first bevel gear to rotate, the first bevel gear is engaged with a second bevel gear and a third bevel gear, and a mandrel and a connecting shaft are driven to rotate reversely, therefore a plurality of stirring plates and a spiral stirring cylinder are driven to rotate reversely, smashed feed raw materials are effectively stirred and mixed, and full mixing of all the raw materials is guaranteed.

Description

technical field [0001] The invention relates to the technical field of feed processing equipment, in particular to a closed premixing device for biological feed production. Background technique [0002] Biological feed refers to the general term for feed products developed through bioengineering technologies such as fermentation engineering, enzyme engineering, protein engineering, and genetic engineering using feed materials and additives permitted by relevant national regulations. [0003] The application number is 201210489400.4 to provide a feed premixing device, including a mixing box, a motor, and a drive shaft keyed to the motor; the drive shaft runs through the inside of the mixing box and is provided with several a stirring plate; the upper part of the mixing box is provided with a material inlet. The feed is stirred by the stirring plate arranged in the mixing box, and the feed is stirred in the way of horizontal stirring, and the feed entering the mixing box can ...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing feed mixing devices use the screw feeder to feed the material, but after the screw feeder feeds the powder, the powder is easily formed into a lump, and the powder in the shape of a ball is stirred. It is not easy to be broken up, resulting in uneven mixing of the powder and low mixing efficiency; and the traditional feed premixing device generally cannot cut and filter the feed, and it is often impossible to fully mix the feed due to the large volume of the feed during mixing.
