Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The purpose of the invention is to provide the ability to configure the cutter to work in different technological modes. The milling cutter comprises a shaft 1 with disks 2, 4 alternating with knives 3, 5 fixed alternately rigidly and freely in it, as well as a supporting element, for example a casing 6. The disks 4 are connected to the shaft I by means of a planetary gearbox. The axes of satellites 8, 9 of the reducer are fixed relative to the casing 6. The disks 4 have a coupling 15 for connection with the shaft 1. When the axes of the satellites 8, 9 are connected to the casing 6 by means of locking rods 13 and the coupling 15 is turned off, the disks 2 and the disks 4 rotate in opposite directions . When the rods 13 are removed and the clutch 15 is turned on, the disks 2 and suits 4 rotate in the same direction. It is possible to operate the cutter, for example, when removing a part of the rods 13 with the coupling 15 turned off, the corresponding discs 4. 2 Il. o "s (l tfl

Description

This invention relates to agricultural machinery industry.

The purpose of the invention is to provide the ability to customize the cutter to work in different technological modes. FIG. front tillage cutter shown; in Fig.2 - section aa in Fig.1.

The tillage cutter contains I blades 2 rigidly mounted on the shaft with L-shaped knives 3, between which disks 4 with flat blades 5 are freely mounted, as well as a bearing element, for example a jacket 15, a closing shaft 1 with disks 2 and 4. The disks 4 are connected to the shaft 3 by means of a planetary gearbox, including an internal gear gear 7 mounted on the disk 4, the teeth of which 20 are meshed with the gears of the satellites 8 and 9, in turn meshed with the central gear wheel 10, fixed on shaft 1. Satellite axles 8 and 9 25 rotate in hub bearings 11 freely mounted on the shaft J. In the slot 12 of the hub 11 a locking pin 13 is installed with the other end entering the groove 14 of the casing 6. The ES disk 3 has a sleeve 15, for example a ratchet, through which it can connect with shaft 1.

The cutter works as follows. Together with the shaft 1 driven from the tractor's power shaft, the rigidly mounted disks 2 with L-shaped knives 3 and the gear wheel 10 rotate, which transmit the rotation to the disks 4 with flat blades 5 through satellites 8 and 9 Snoring

clutches 15 are off at this time. The knives 5 rotate in the direction opposite to the direction of rotation of the knives 3. and cut the soil into strips- and the knives 3 of the discs 2, rotating along the course of the unit, process these strips, removing chips.

For operation in another mode, all the locking rods 13 are removed, and the ratchet sleeves 15 are turned on, the disks 4 are connected to the shaft 1. All the disks 2 and 4 rotate in one direction from top to bottom.

For simultaneous efficient processing of, for example, soil bands compacted by tractor wheels, locking the rods 13 is left only on those discs 4 that process the compacted soil strips, while the ratchet sleeves 15 on these discs 4 remain off.

Claims (1)

Invention Formula A tillage cutter containing a carrier element and a shaft on which alternately rigidly and freely mounted disks are mounted with working bodies, each freely mounted disk being connected to the shaft through a gearbox, which allows its adjustment to work in In different technological modes, a freely mounted disk has a sleeve for connecting it to the shaft, and the gearbox satellites have a means for fixing them relative to the supporting element. ///////// fe.f
