SU1660611A1 - Combine for harvesting readily shedding crop seeds - Google Patents

Abstract

The invention relates to agricultural machinery, in particular to combines for harvesting seed plants of desert plants. The goal allows an increase in the collection of biologically valuable seeds by increasing their release and reducing trauma. The harvester contains a header with a reel and a screw, the working bodies of which are equipped with elastic plates 3.5, an inclined chamber with a wavy bottom 7, a straw separator with an extension 9 and a receiving beater 10 installed above it with a grid 11 hinged on the body. A pusher is mounted on the beater, and the limiter 12 of its vibrations is installed on the back of the grille. Selection of seeds occurs by the working bodies of the reel and auger, as well as the receiving beater and straw separator, while oscillations of the beater lattice help to increase the release of seeds, reduce their damage and prevent clogging of the beater. 2 hp f-ly, 3 ill.

Description

The invention relates to agricultural machinery, in particular to a device for harvesting testes of herbs.

The aim of the invention is to increase the collection of biologically valuable, high-quality seeds by increasing their allocation and reduce injury.

Figure 1 shows a harvester for harvesting seed plants, desert plants; figure 2 - receiving beater with a bar grill; in Fig.3 - section aa in Fig.2.

The combine for harvesting seeds of easy-to-spray plants contains a header 2 mounted on the housing 1, on the reels of which are mounted elastic pads

3. The blades of the auger 4 of the header are also equipped with elastic pads 5. The inclined chamber 6 has a wave-like bottom 7. Before the straw separator 8, an extension 9 of the straw separator is installed. A receiving beater 10 is mounted above the front end of the straw separator extension 9, provided with a bar grate 11. A limiter 12 of its oscillation is installed on the reverse side of the bar grate 11.

The straw separator 8 is equipped with removable, separating plates 13 selected depending on the conditions of harvesting and the state of the crop being harvested. The straw separator extension 9 is pivotally connected to the straw separator and is made as part of a key.

The grating 14 for wind-screen cleaning is installed on the housing 1 by means of a regulator 15, which is designed to change the amplitude of oscillation of the sieves.

To change the performance of the spike auger 16 and the spike elevator 17, they are equipped with a set of sprockets that are set depending on the operation of the combine on the spike auger 16.

The operation of wind-screen cleaning can be controlled by changing the air flow of the fan (not shown) due to the variator and dampers.

At the rear of the combine, a swather 18 is installed.

To bring the lattice 11 into vibrational motion, a pusher 19 is mounted on the beater, interacting with both the vertical part of the lattice and its end part.

The harvester works as follows.

When the combine harvester moves the reel straps, the stems are brought to the cutting apparatus, where they are cut and transported together with elastic seeds that crumble when cutting with seeds 3 along the header bottom, cleaning the cutter bar. The header auger directs the stalks to its central part and to the inclined chamber, while the seeds are beaten out with elastic screw overlays. In the inclined chamber, the mass is also exposed to the wavy bottom 7 and the conveyor. The bottom 7 is removable and can be replaced flat. At the exit of the inclined chamber, the mass is exposed to a beater 10. directing it to the straw separator extension 9. in this case, the layers of mass move relative to each other due to the alternating action of the beater blades on it 10. The alternating action of the beater blades is due to the oscillation of the lattice 11 from exposure to the beater, which changes the area of interaction of the next blade relative to the previous one, while the release of seeds increases with decreasing their injury, and also reduces the likelihood of clogging of the beater, since the grill is constantly exposed to the pusher 19 both in its initial part, and final. In this connection, it performs a complex oscillatory motion, due to which it cleans itself.

From the straw separator, the mass falls onto the swather and is formed on the field into the swath.

Instead of the swather, a chopper can be installed, and a pick-up on the header. In this case, the mass is taken from the finished roll, and the collection of the crushed mass is carried out in a tow hitch.
