Description

The present invention relates to agricultural production, in particular to devices for cutting feed rolls into parts.

Known cutter rolls containing a cutting path, cantilever mounted on the carriage and located on the axis of symmetry of the device for gripping and orienting the roll.

The carriage is mounted with the possibility of vertical movement (see ed. St. USSR No. 1588320, Cl. A01F 29/00, 1988). The above device provides a complex mechanism for moving the carriage and the drive mechanism of the cutting circuit and the orientation mechanism of the roll.

The mechanism includes cam and friction clutches, two-arm levers, a carriage position lock. In the process of operation of the cutter, continuous orientation of the roll is required.

The closest to the proposed design and the result achieved is a roll cutter containing a vertical shaft, a feed conveyor and a roll-cutting device installed at the base of the shaft (see ed. St. USSR No. 1762795, Cl. A01F 29/00, 1987) .

In the process of using the above cutter, two parts of the roll are obtained in which the internal connections of the stems are not sufficiently weakened, and the further preparation process for feeding the obtained parts of the roll requires additional processing.

The objective of the proposed technical solution is to provide a sharp weakening of the internal connections of the stems of the roll by cutting it in different planes, which will allow the use of feed dispensers of various types, including those equipped with beater feed separators, and the use of various types of technical means for preparing feed mixtures.

This object is achieved by the fact that in the cutter aft rolls containing a vertical shaft, on the walls of which slots are made, a conveyor for loading the shaft and a cutting device installed at the base of the shaft with a drive mechanism, a cutting device is made in the form of cutting devices fixed at different levels of the shaft installed with the intersection of their projections on the horizontal, and on the walls of the shaft slots are made oriented with the location of the cutting apparatus, while the shaft is mounted with by opening the cutting device, and cutting devices of different levels are located at right angles.

The technical result consists in the fact that cutting machines of different levels, installed with the intersection of their projections on the horizontal, provide in operation the production of a numerically greater number of divided parts of the monolith of the roll in comparison with the location of the same number of cutting devices, but installed without their intersection, there is no need orientation of the roll when loading into the mine.

According to the patent and scientific and technical literature, the claimed combination of essential features is unknown, which allows us to judge the compliance of the proposed technical solution with the level of the invention.

Figure 1 presents the cutter of the feed rolls, a side view in section, figure 2 is the same, a plan view, figure 3 is the same, a section along aa in figure 2.

The feed roll cutter comprises a vertical shaft 2 mounted on the frame 1, a conveyor 3, equipped with rake 4, mounted on the traction organ of the conveyor. The mounting step of the rake is made in excess of the expected roll dimension, a grill 5 is installed on the upper edge of the shaft 2, made in the form of a series of rods fixed obliquely to the side of the shaft at intervals and with the possibility of their intersection with the teeth of the rake 4.

Above the bottom edge of the shaft is mounted a roll-cutting device containing cutting devices placed at different levels. The devices are mounted with the intersection of the walls of the shaft 2, while in the walls of the shaft are made slots 6.

Two cutting apparatuses are mounted at the upper level, which ensures a stable roll position; at the lower level, one cutting apparatus is mounted. The number of cutting devices may be different. In a projection on a horizontal plane, cutting devices of different levels are mounted with intersection at right angles.

Each cutting device (a cutting device from fodder harvesting equipment can be used) contains a beam 7 with contradictions (segments) and a knife blade 8.

The adjoining of the blade to the timber is provided by the clamps 9. The blade is connected to the drive mechanism. The knife blade drive mechanism comprises a crank 10 mounted on the bearings, connected to a knife blade 8 by a connecting rod 11. The rotation of the crank shaft 10 is transmitted from the electric motor 12 by a belt drive 13.

To transmit the movement to the knife blade of the lower cutting apparatus, a bevel gear 14 is mounted on the end of the crank shaft 10, and the other bevel gear 15 is connected by a shaft to the upper gear 16 of the gear pair, and the lower gear 17 is connected to the shaft of the crank 18. Gears 16 and 17 provide the possibility of transmission of motion knife blades placed at different levels from one electric motor 12.

The crank 18 connecting rod 19 is connected to the knife blade 20 of the lower cutting apparatus. The knife blade drive is mounted on the plate 21, mounted on the frame 1, and may have a different design. A visor 22 is fixed on the upper edge of the shaft. The design of the frame 1 makes it possible to place a feeder 23 under the shaft 2.

Cutter feed rolls as follows. By conveyor 3, the roll is fed to the upper edge of the shaft 2, and in the area of rotation of the traction body, the roll rolls off the rake 4 and along the inclined grate 5 and with the participation of the visor 22 is sent to the shaft, where it is located above the cutting devices. The motor 12 is turned on, the belt drive 13 transfers the rotation to the shaft of the crank 10 and through the bevel gears 14, 15 the rotation is transmitted to the shaft of the crank 18 with the participation of gears 16 and 17.

When the crank 10 and 18 are rotated by the connecting rods 11 and 19, the reciprocating movement of the knife blades 8 of the upper level of the knife apparatuses and the knife blade 20 of the lower knife apparatus is provided. The monolith of the feed cut into parts by the upper knife apparatuses, under its own weight, is lowered along the shaft and subjected to sectioning by the lower knife apparatus.

The walls of the shaft, overlapping the position of the knife devices, keep the roll from collapsing into divided parts when lowering the parts of the roll from the upper knife devices to the lower.

Thus, the location of the knife devices at different levels and installed with the intersection of their projections on the horizontal increases the efficiency of using devices for cutting the roll. The placement of the two upper cutting devices and one cutting device at the lower level, fixed at right angles to the upper, provides for cutting the roll into six parts, in which the internal connections of the stems are weakened and can be loaded directly into the body of the feeder 23.
