Forage mill mixer

Abstract

The invention relates to a forage mill mixer. The forage mill mixer comprises a hopper, wherein the lower end of the hopper is provided with a conical section, the bottom of the conical section is connected with a blending bin, an auxiliary hopper and a feeding and milling device are connected with both sides of the blending bin, and the ratio of the distance a between the lower end of a transferring cylinder in the hopper and the bottom of the conical section to the height b of the conical section is 0.2-0.8, wherein one end of the feeding and milling device, close to the blending bin, is provided with at least one air return pipe to be communicated with a feeding casing pipe. The invention enables even a small amount of forage to circulate in the hopper, thereby improving the operation flexibility of the device; the feeding and milling device is connected with the feeding casing pipe by the air return pipe, thereby circulating the air; and the air from the air return pipe can help the feeding, thereby improving the feeding efficiency and reducing the dust emission.

Description

technical field [0001] The invention relates to a feed grinder, in particular to a feed grinder. Background technique [0002] In the existing feed crushing mixer, the feed crushing device uses the centrifugal pump inside to generate negative pressure, and uses the weight attached to the pump blade and the screen to crush the feed, and the crushed feed enters the mixing bin and auxiliary hopper. After the feed is mixed, it is transported to the hopper by the conveying roller, and then stirred evenly in the hopper. The existing problem is that the existing feed grinding mixer needs at least 250 kg of feed to start mixing, because the transmission cylinder and the conveying roller set in the hopper can promote the feed to form a circulation in the hopper, so that the feed and auxiliary materials can be evenly mixed, and the feed can be lifted. The premise is that the feed in the hopper must not pass through the lower end of the transmission cylinder. [0003] The existing fe...

AI Technical Summary

Problems solved by technology

The existing problem is that the existing feed pulverizer needs at least 250 kg of feed to start mixing, because the transmission cylinder and the conveying roller set in the hopper can promote the feed to form a circulation in the hopper, so that the feed and auxiliary materials can be evenly mixed, and the feed can be lifted. The premise is that the feed in the hopper must not pass through the lower end of the transmission cylinder

[0003] The existing feed crushing device is equipped with an air outlet, although there is a cloth bag to filter the dust on the air outlet, but the filtering effect is not good, and the dust is still very large in actual use

And it would be a pity to waste the wind generated by the centrifugal pump

[0004] When bagging at the discharge port, it is inconvenient to operate the discharge valve because it is often necessary to pull the bag mouth with both hands
