Abstract

The invention relates to agriculture, in particular to devices for grinding and spreading litter on livestock farms. The purpose of the invention is to increase work efficiency. The grinder contains a cylindrical body 1 with a cutting mechanism placed in it and a loading neck 8 vertically mounted on the body. When the disk 2 is rotated by the drive 14, the rippers 3 choose straw from the bale, which is then crushed between the knives 4 and the opposing plates 7. By means of air pressure, the chopped straw created by the blades 5, is ejected through the hatch. The cylindrical shields 9 serve to fix the bale and form through channels 10 for air into the grinding zone. Due to the uninterrupted supply of air, the uniformity and efficiency of the device is ensured, the possibility of overflowing the cavity of the body 11 with chopped straw is prevented. 2 Il. J

The invention relates to agriculture, in particular to devices for grinding and spreading litter used on livestock farms.

The purpose of the invention is to increase work efficiency.

FIG. 1 shows a straw bale chopper, longitudinal section; in fig. 2 - the same, top view.

The straw bale shredder is equipped with a cylindrical body 1 with a disk 2 placed on it, on the upper surface of which are mounted rippers 3 and knives 4, and on the bottom blades 5 are attached. From above, case 1 is closed by a cover 6 to the lower surface of which opposite blades 4 are attached 7, and on the upper surface there is a loading opening 8, provided with cylindrical shields 9, fixed inside the loading opening 8 with formation of channels 10 for the passage of air into the grinding zone. The disk 2 with the rippers 3 and the knives 4 and the shear plates 7 form a chopper cutting mechanism. The space bounded by the wall of the housing 1, the disk 2 and the knives 4, forms the cavity of the housing 11, which is connected to the discharge hatch 12. The disk 2 is mounted on the shaft 13 of the drive device 14.

The grinder works as follows.

A bale of straw is placed in the loading neck 8 in the space between the shields 9,

eight

which do not clamp the bale, but do not allow it to turn. The rippers 3 installed on the rotating disk 2 loosen the bottom of the bale and tear straw out of it, which is carried along by the air flow generated by the rotation of the blades 5, under the action of centrifugal force, is thrown to the periphery of the disk 2 and crushed between the cutting

 the surfaces of the knives 4 and the shearing plates 7. The crushed straw enters the cavity of the body 11 and, through the blades 5, is pumped into the ejection port 12. Air to ensure the smooth and even discharge of the straw enters the

the cavity of the housing 11 through the channels 10. The disk 2 is driven in rotation from the drive device 14, which can be used as an electric motor. It is also possible to use a selection shaft.

Claims (1)

Claims: A straw bale chopper that contains a cylindrical body with a cutting mechanism and blades placed in it, a loading neck vertically mounted on the body, and a drive characterized in that the loading neck is fitted with shields 0 inside the loading neck with the possibility of forming channels for the passage of air into the grinding zone.
