Abstract

This invention relates to feed preparation machines for utility households. The aim of the invention is to reduce metal consumption by reducing overall dimensions. The feed grinder contains a frame 1, an electric motor 2 mounted on it, which, through the drive pulley 3 of the V-belt transmission 4 and the V-belt, transmits rotation to the driven pulley 5. The belt-drive transmission 4 is equipped with a protective casing 10, in which the hopper 11 is placed, and installed in the end of the working chamber 9 The disk 18 of the driven pulley 5 contains chopping working bodies for root crops and grassy feeds, made in the form of knives 24 and 23, respectively. Rotating together with the disk 18 and fixed on the brackets 21, the knives 23, when interacting with the shearing plate 15, grind the grassy feeds fed through the neck 14 to the required length. The root crops fed to the bunker 11 are crushed into slices by knives 24 secured in the radial windows of the disk 18 and, when they enter the working chamber 9, are comminuted by the rotating knives 23, mixing with grassy foods. 2 hp f-ly, 5 ill.

Description

On the disk of the driven pulley 5 placed chopping working bodies for root crops and grassy food, made in the form of knives. The knives 23 rotating together with the disk and secured to the brackets 21, when interacting with the shearing plate 15, grind the grassy feeds fed through the neck 14 to the required length. The root crops fed to the bunker 11 are crushed into slices with knives secured in the radial windows of the disc, and, when they fall into the working roll 9, are ground by the rotating blades 23, mixing with grassy foods. 2 hp f-ly, 5 ill.

FIELD OF THE INVENTION The invention relates to feeding machines for utility households.

The aim of the invention is to reduce metal consumption by reducing overall dimensions.

In Fig.1 shows the chopper plan with a longitudinal section; Fig. 2 shows a section A-A in FIG. on fig.Z - view B in figure 2; figure 4 - section bb In fig.Z; figure 5 - section GG in figure 3.

The feed chopper includes frame 1, an electric motor 2 which, through the driving pulley 3 of the V-belt transmission 4, transmits rotation to the driven pulley 5 fixed rigidly on the shaft 6 rotating in two bearings 7 and 8. On the shaft 6 side, the working wheel adjoins camera 9. On the opposite side of the pulley 5 together with the pulley 3 is closed by a protective casing 10. In the casing 10 there is a receiving bunker 11 of root crops. Between supports 7 and 8 on the shaft 6 there is installed a worm-gear gear 12 of the drive of the feed rollers 13 located in the receiving neck 14 of the working chamber 9. A buckle 15 is installed in the front part of the receiving neck 14, and the receiving chute 16 is adjacent to the rear. 5 (FIG. 3) consists of a rim 17, a disk 18 and a hub 19. The disk 18 has radial windows 20. Approximately perpendicular to the windows 20 from the side of the working chamber 9 on the disk 18 are fixed brackets 21 on which the holders 22 of the circular knives are fixed 23 for grinding Grass feeds. In windows 20, knives 24 are installed at an angle of attack for chopping root crops. Knives 24 to disk 18 are secured by brackets 25 and bolts 26. Knife departure

is adjusted by moving them along the brackets 25. For this, there are grooves in the knives (not shown). The knives 23 are fixed to the holders 22 by means of bolts 27 and nuts 28. Bolts 29 and lock nuts 30 are installed to adjust the clearance between the knives 23 and the shearing plate 15. The working chamber 9. and the bunker 11 of root crops are made in such a way that their end edges located from the side of the driven pulley, go inside the rim 17.

The grinder works as follows.

When the electric motor 2 is turned on, the rotation through the driving pulley 3 and the belt drive 4 is transmitted to the driven pulley 5 and through the shaft 6 with a worm gear 12 to the feed rollers 13. Manual grass is evenly fed into the receiving tray 16 to the feed rollers 13, which pick up the material , compact it and feed it through the receiving neck 14 into the working chamber 9. The knives 23 rotating together with the disk of the pulley 5 when interacting with the shearing plate 15 grind the grassy forage to the required length. The degree of shredding is controlled by moving the screw into the screw-gear 12. When feeding the previously washed root crops into the hopper 11 due to the knives 24 being installed at the angle of attack, the roots are ground into slices as thick as the amount of knives 24 flying out of the disk 18. Cut slices through the windows 20 They are directed to the working chamber 9, where they are additionally crushed by the rotating blades 23 and mixed with grassy feeds. Thus, joint and separate grinding of root crops and grassy feeds takes place.
