Description

In existing harvesting machines, the reel (in grain harvesting machines, transporting belts in hemping machines), or chains (in corn harvesting machinery) serve to lay the stalks on the platform. The reel, which affects the upper part of the stem, inevitably causes loss of grain when harvesting grain, and loss of cobs when harvesting corn (grain combines).

The proposed rotary disk-rotary apparatus, harvesting without a reel, acts on the lower part of the stem (butt) and thus provides the possibility of harvesting without loss.

The rotary disk apparatus is shown in FIG. 1 and 2. The device is designed to cut the stems of the crop to be harvested and place them on the platform of the harvesting machine (combine) without the reel, transporting belts, chains, and others.

The rotary disk apparatus consists of several sections, which are mounted on the front bar of the header of the harvesting machine. Each section has the following details.

A steel disc 1 with a diameter of 300-360 mm for cutting thick-stemmed crops (maize, sunflower, hemp, castor beans, etc.) has a circular sharpening at an angle of 15 °. For cutting fine stem crops (cereals, alfalfa grasses, clovers), a disc is used with segmented plates fixed around its circumference, which are cutting elements. The disk is mounted on a vertical drive roller 2. The anti-compressive plate 3 fixedly mounted on the square 4, is set at an angle of 30-40 ° to the line of movement of the aggregate when cutting thick-stem crops, and when cutting thin stems at an angle of 60-70 °. The rotor 5 with edged rubber strap slats 6 drops onto the platform butt forward the cut stems. The stalk guide shield 7 provides the direction of movement of the upper part of the stem. A conical shield 8 covers the top of the rotor 5 and protects the upper part of the stem from the impact of the rotor bars 6. A longitudinal shield 9, located along the bar between the sections, prevents the stem from the platform from moving forward from the platform along the harvester.

The vertical drive roller 2 of the transmission mechanism is rotated in a two-hole sub-support 10, in a housing in the housing //. Horizo .lipy gidrivodnaya shaft 12, mounted on 3 ball bearings 13, will give the rotation of the vertical; P) the 1st drive of a va.tikam 2 of all parts of the apparatus. Koichesk. gears 14 and 75 transmit the rotation from the horizontal shaft 12 to the vertical roller 2. The shaft 12 is rotated from the transmission mechanism of the harvesting machine.

When the harvesting machine is moving, the plants of plants 15.1 (16) (Fig. 2) are sent to a solution of the direction of the pair (a disk).

The stalks are cut when the disk is worn / at a speed of 300-500 rev / min.

By bars 6 of the rotor 5, the butt of the stem is guided along the bottom of the stem of the 7th power and is dropped along the conveyor web along the front. The upper part of the stem slides along the upper oblique edge of the guide shield 7 and naziaeT onto the web along its course. When harvesting thin stems, the wave of the disc / should be combined with the wave of the bar 6 of the rotor 5. Therefore, the bar 6 should be fixed above the segments of the cutting unit.

The design features of the disk cutting apparatus and the technological process of cutting the stems allow one to combine its work with the work of a rotary thrower of the stems onto the platform and combine them into one unit. The apparatus lays the stems in a certain order, while the reel lays them loosely. The strips b of the rotor 5, acting on the butt of the stem, throw the latter, depending on the position of the stem of the stem 7, in the right direction. The fruit-bearing part of the stem is not subjected to mechanical stress, so the loss of grain (or cobs) on the ground during the operation of the apparatus is completely excluded.

When installing the header of the disc-rotary combine harvester, the cutting unit and the reel are removed. The front bar of the platform is secured with a corner bar with sections of a rotary rotary apparatus assembled on it.

The subject of b) e te and

1. Rotary rotary apparatus for cutting and planting plants per gram (. Atform of a harvesting machine using de-grating grain, cutting discs, anti-ribbing plates with rods, characterized in that, in order to mow starchy and thin stem crops without using the reel and reducing crop losses, as well as laying the stems on the conveyor bed with the forward cuts in the direction of its movement, back comfortably along the machine, the device is equipped with conical, longitudinal, rotatable stem-bearing panels, and rotivorezhushie nlastiny arranged removable and installed at an angle of 30-40 ° to the line of movement manshny tolstostebelnyh when harvesting crops and 60-70 ° -with tonkostebelnyh harvesting crops.

2. The form of the apparatus according to n. 1, so that, in order to ensure the reliability of the stems grasping the combs, as well as the possibility of harvesting various crops and dropping them onto the platform after cutting the butt at the desired position at different rates of translational movement of the mash, the slats on the rotors are made-non-flexible, edged with a rubberized strap and attached to the disk in the radial direction or at an angle to its radius.
