Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, devices for milling grass. The purpose of the invention is to increase the uniformity of the impact of the rotor and deck on the stems to speed up the drying. The device consists of a frame 8 on which the cutting apparatus 1 is installed, a flattening rotor and a deck, divided into sections 6 according to the width of the grip. The upper end of each section 6 is spring-loaded, and the lower end is hinged to the frame 8 by means of a device 7 for adjusting the clearance. This allows for changing the feed rate of the bevelled mass into the device to automatically maintain the clearance required for processing by turning the section 6 in the radial direction relative to the rotor. 5 il.

Description

The invention relates to agricultural harvesting machines, in particular to devices for milling grass.

The purpose of the invention is to improve the uniformity of the impact of the rotor and the action on the stems.

FIG. 1 is a schematic of a device for treating grass stems, view, juice; in fig. 2 - the same, top view; in fig. 3 - the same, with a rotary cutting unit; in fig. 4 - the same section; in fig. 5 shows the node I in FIG. 1. In the design, over the cutting apparatus 1 (Fig. 1), over the entire width of the grip of the device, a flattening grass processing device is installed with Y-like working members 2. The working members on the rotor tube 3 are arranged along helical lines converging in the middle rotor. A deck 4 is installed above the rotor of the device (Fig. 1), which is a structure made of a metal sheet bent into a groove. On the working surface of the deck the cells 5 are stamped with the convex side in the direction of the rotor. Structurally, the deck is made of several sections 6 (Fig. 2), independent of each other, with devices for adjusting the gap 7 (Fig. 1) located at the lower ends of the deck sections. The upper part of each deck section is spring-loaded relative to the frame 8 (Fig. 2). The spring stiffness 9 is varied with nuts 10, 11, and the gap size at the output of the deck is adjusted by nuts 12, 13.

A mass stacker is located in the rear part of the device, consisting of an obliquely mounted breakaway sheet 14 (Fig. 1), two dividers 15 (Fig. 2) of the cut of the mass, which prevent the grass from entering under the sa 16 self-propelled chassis 17. The upper area of the device between the deck and the baffle plate is covered with a grille 18. A bending bar 19 is located in front of the cutting unit.

Before the start of mowing grass, the necessary clearance between working bodies 2 and deck 4 is established. The size of this gap is established depending on the average feed of mass into the device and the outcome is determined from the average yield of the crop to be harvested and the speed of movement of the unit. The gap is set the same in all sections of deck 6. Entry Clearance

set by devices for adjusting the gap 7. The clearance at the outlet between the working bodies 2 and the upper end of deck 4 is set by nuts 12, 13. The stiffness of the spring 9 is set by nuts 10, 11 based on the magnitude of the fluctuations in the supply irregularity of the grass to be removed. The check for correct installation of spring stiffness 9 is the mobility of the upper edge of deck 4 when the mass feed rate fluctuates in areas with uneven grass stand.

The device works as follows.

The plant mass is deflected forward by the beam 19 (Fig. 1) and is cut by the cutting apparatus 1. Due to the presence of the beam 19, the action of the working bodies 2 is first carried out on the lower part of the plant, causing it to bend and pull into the gap channel with a cut (komlem). Due to the large slip during the engagement by the working bodies 2 of the rotor 3, the stem moves at the beginning of deck 4 at a slower speed than at the exit. The lower part of the plant and the place of the cut are subjected to the greatest impact of the working organs 2, which contributes to the acceleration of the process of moisture return of the plant as a whole and the uniformity of drying of the stems and leaves.

Deca 4 cell surface slows down the processed material when moving in the channel of the device, thereby making it possible to advance the material by the rotor and its processing. This means that the covering tissue of the stem-cuticle is destroyed by friction, bending, and scratching by the slats of the working bodies 2. The gap between the working bodies 2 and the upper end of deck 4 is in the process of mowing. With an increased mass feed on one of the sections of deck 6, the gap increases due to the upper edge of the deck in the radial direction and compression of Spring 9. As the supply decreases to the amount needed for optimal grass processing, the upper edge of the deck returns back due to the rigidity of the previously compressed spring 9 in the original position and the establishment of the necessary clearance for the filing.
