Description

The invention relates to agriculture, in particular to the grinding apparatus of forage harvesters.

A grinding apparatus is known, comprising a casing, a rotating drum with knives, an anti-roll bar and a recter with rows of prohibitive elements made in the form of rods, on the working surface of which radial acute-angled teeth are cut along the entire length

The disadvantage of this device is the low quality of work due to the weak activity of the shear elements with the drum leather.

The purpose of the invention is to improve the quality of grinding materials.

This goal is achieved by the fact that, in a material grinder, comprising a casing, a rotating drum with knives, a taller bar and a recter with rows of prohibitive elements made in the form of rods, where the grinding drum from the ends of the supports is equipped with flywheels with diametrically mounted outside elastic roller elements with the possibility of free rotation. In addition, the rokter rods are equipped with elastic-elastic bushings.

Fig 1 shows a diagram of the grinder materials; Fig 2 - view A in Fig 1

The material grinder contains (Fig. 1) a casing 1, a rotating drum 2 with knives 3, a recter 8 with rows of bars 4, at the end of which elastic elastic bushings 5 are installed. Flywheels 7 are installed at the ends of the supports of the shaft of the grinding drum 2 and are equipped with diametrically mounted outside elastic roller elements 6 with the possibility of free rotation. The rods 4 rekattera 8 from both ends are supplied with elastic-elastic bushings 5

Shredder materials works as follows.

When the drum 2 is rotated (Fig. 1), the vegetable mass, for example cotton stalks, is cut by knives 3 at the shearing bar (in Fig. 1). The crushed particles are moved by knives 3 along casing 1 to recteter 8. When particles hit rods 4, knives 3 are split and removed by air flow from recatter zone 8 to unloading from casing 1. At the same time, diametrically mounted outside roller elements 6 rotate flywheels 7 cyclically interact through the sleeve 6 with rods 4, the saso

The installation of elastic roller elements 6 and elastic-elastic sleeves 5 cm thickens the dynamic loads during the interaction of the latter with each other, thereby improving the mode of operation of the device. Also, the proposed device eliminates the kinematic transmission, simplifies the design of the drive of the recaster rods. At the same time, the quality of work of the apparatus itself is improved. The invention can be used in drum-type grinding devices on domestic and foreign fodder harvesters.
