Abstract

Usage: in agriculture, in particular in fodder production, SUMMARY OF THE INVENTION: Stalk feed is compacted and crushed with a jet of high-pressure liquid with microadditives.

Description

 The invention relates to the field of feed production for livestock, in particular, to methods for grinding stalk and other feeds, and can be used in feed workshops of livestock farms and complexes. ; ,.; :. ; :: - .h. ....: -:

The purpose of the invention is to improve the quality of food preparation and reduce dustiness. :.:; . . :: h In FIG. 1 schematically shows pr. a circuit diagram of the implementation of the proposed method, in FIG. 2 - view A.,

A schematic diagram of an implementation of a method for grinding feed includes a feed conveyor 1, sealing rollers 2 and a roller table 3, which are installed in series. Behind the roller table 3, a grate is installed - a conveyor 4, which performs the functions of contradicting and moving the crushed fodder mass. The cutting device consists of a liquid-jet cutter 5, having an output nozzle with a diameter of about 0.15 mm with a carriage b, which is mounted on the shaft 7 with the possibility of reciprocating movement (shaft 7 has a right and left helical groove, i.e. endless thread) ,

Under the grill - conveyor 4 there is a collector (tank) 8 of spent liquid. For the removal of the ground feed mass there is a conveyor 9, over which a hopper 10 is installed for introducing insoluble feed additives into the feed.

The method of grinding feed can be carried out as follows. The feed feed 11 is loaded onto the feed conveyor 1 (stalk, fiber and other feeds) and fed to the rollers 2, where it is compacted to a certain thickness S and then fed to an intermediate conveying device, for example, a roller conveyor 3. From the last feed to be chopped is fed to the conveyor grill 4 and at the same time, the working fluid is fed to the cutter 5 under high pressure (P 20 ... 600 MPa or more). The cutter 5, moving together with the carriage 6 relative to the shaft 7, grinds the feed 11. In this case, soluble additives (protein-vitamin additives, drug additives, etc.) are added to the working fluid in advance, and insoluble additives are fed through the hopper 10. The crushed feed is discharged by the conveyor 9 to the feeders, in

feeding devices or for storage, and the spent liquid enters the collector (container) 8 and drain or cleaning for reuse is further extended.

An example of specific implementations of the proposed method.

It is necessary to prepare compound feed from stalk feed with the addition of protein-vitamin supplements (BVD) and premixes.

f | a feed conveyor 1 with translational speed v - 0.3 m / s 1080 m / h and a width of 1.5 m feeds stalk feed with a density of 7 t / m and is compacted by rollers 2 to a thickness S of 0.02 m ( the gap between the rollers 2 is adjustable). The compacted feed enters the roller table 3 and then to the grate — conveyor 4. The BVD of the required amount is introduced into the working fluid in advance, and the hopper 10 is loaded with premixtures (fillers): The feed received on the grate conveyor 4 is crushed with a high-pressure liquid jet and at the same time, BVDs are added to the feed. The chopped feed enters neither the discharge conveyor 9, where premixes are added to it from the hopper 10, and the finished feed is fed to the animal feeders.
