Description

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to fodder harvesting machines for - harvesting of crushed fodder0

A known baler includes a pick-up, a feeder, a piston with a drive located in the bale chamber, at the outlet of which there are straight knives intersecting the cross section of the bale chamber with their planes. For such a design of knives, a large frontal resistance structural and technological difficulties of manufacturing and operation is therefore proposed a device containing a pick-up feeder, a piston driven, located in the bale chamber, the output of which, from the mouth of the norlech, is directed backwards, other parts which interact with the planes, on which the edges of the blades of the knives intersecting the section of the press chamber with their planes, and the mass conduit are located. similar features, this device is closest to the one proposed and is taken as a prototype,

However, the use of -shaped knives, consisting of the components in which the sharpening jaasks are located on each side other than the adjacent side, leads to large moments of twisting knives during cutting, which leads to increased energy costs and inconvenience when replacing the knife

The purpose of the invention is to reduce energy consumption for grinding and increase ease of operation.

This is achieved by the fact that the baler containing a piston located in the bale chamber, at the exit of which there are нож-shaped knives with mating side planes, differs in that the cutting edge of the components of the knives is made on one-sided sharpening and in the middle part - two-sided „

The invention consists in arranging the symmetrically sharpening section of the knife in front of the one-sided sharpened area and before intersecting the edges of the blades. Thus, it is possible to avoid stuffing the material at the junction of the parts-like knives from different opposite sides and edges. the blades are in contact, and at the same time, the torque of the blades is reduced, t, k0 before the intersection point, the internal adjacent cutting edges are formed by chamfering from two planes on Ozha, with the result that the external forces acting on this section are balanced, not causing excessive moments 1 to resist bending in the knife and thus reducing energy consumption. In addition, parts of the knives become interchangeable and can be connected by both ends.

Fig „1 shows a baler, top view; FIG. 2 is a view along arrow A in FIG. 1; FIG. 3 is a view along arrow B in FIG. 1; in fig „b view along arrow B in fig. 3j on section GG on fig „; in FIG. DD in FIG.

The baler consists of a frame with a wheel drive 1, on which the shaft picker 9 and the knives 9 are mounted on the front and on the right. There are holes on one end of the knives part that are connected to each other and are touching at the junction with the planes opposite to sharpening. The knives 9 at the joints are on different, opposite sides and the cutting edges of the blades of the parts of the knives are in contact. The inner adjacent edges of the blades before the point 10 of their intersection have a section located in the middle of the thickness of the knives 9 o, thus, at the end of the knife parts 9, the edge of the blades is on the same plane of the knife, and in the middle symmetrically to the thickness, which determines the interchangeability of the component parts shaped knife

20 9о In the view of the component part of the knife from the side of its blade edge, the edge from one plane of the knife after point 10 with a smooth transition is placed in the middle of the thickness of the knife and in the upper part;

The baler operates in an aggregate with an energy facility and, in a row 6, with a vehicle in motion,

located under the exit of the track 11. When the machine is moving along the roll, the pick-up 2, mounted like all the other components on the frame from the wheels
