Abstract

The invention relates to agriculture, can be used in the harvesting of grain crops with the delivery of ground grain to hospital and reduces the damage to the grain and the energy intensity of the ground mass. The device for harvesting grain crops contains a header with a cross conveyor 2 and an unloading window 3 in which a grinding device is placed, having a horizontal knife rotor 4 and two horizontal shafts 10 located one above the other in front of the rotor 10. Bearing disks 12 are mounted on shafts 10 The knives 13 of the rotor 4 are placed between the disks 11 and mounted on the front and middle with respect to the direction of movement of the masking area of the rotor 4 to prevent chopping of the large part of the cut mass. The oblique stems of the plants are guided by conveyor 2 to the chopping device. The disks 11, when counter-rotating the shafts 10 by fingers 12, feed the bread mass to the knives 13, which chop the stems without chopping the heads. The crushed mass of stalks with unshredded ears, feed conveyor and pneumatic material is loaded into a vehicle that delivers the mass to the hospital, where it is processed further. 2 sec. n. f-ly, 3 ill. -e

FIG. 2

The invention relates to agriculture and can be used in grain harvesting techniques, such as rice, with in-patient mass treatment.

The purpose of the invention is to reduce damage to the grain and the energy consumption of the grinding mass.

FIG. 1 is a diagram of a device for harvesting grain crops, side view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2

The device, made in the form of a field harvesting machine, contains a header 1 with a cross conveyor 2 and an unloading window 3, a shredding mechanism with a horizontal knife rotor 4, a feeding conveyor 5, a discharge fan 6 with an ejector mechanism 7, a pneumatic material 8 for loading the crushed mass in a vehicle (not shown) and a traction engine 9.

The shredding mechanism is placed in the discharge window 3 and provided with two horizontal shafts 10 arranged one above the other in front of the rotor, with supporting disks 11 mounted on them, which have exciting fingers 12. The rotor blades 13 are placed between the disks 11 and mounted on the front rotor 4 relative to the direction of movement of the machine. The grinding mechanism is located in a separate removable housing 14.

The proposed method is implemented using the device as follows.

The cutting heads of the plants cut by the cutting apparatus 1 are laid on the conveyor 2 and fed to the chopping mechanism by them.

The supporting discs 11, when counter-rotating the shafts by 10 fingers 12, feed the cut plants into the grinding zone to the knives 13 of the rotor 4, and then remove the crushed stems from the grinding zone. Since the knives 13 are mounted on the front and middle parts of the rotor 4 with respect to the direction of movement of the machine, only the stalk part of the canted mass enters the grinding zone, and the ear part remains unground. The length of the crushed stalk lengths depends on the type of crop being harvested and the purpose of the ground mass (use it as a form, use to protect the soil from

wind erosion, etc.).

The crushed stalks, together with the unshredded ears, are fed to the conveyor 5 by means of any known mechanisms, such as screw, scraper, pneumatic conveying (not shown). Then, the stems with ears are directed through the ejector mechanism 7 into the pneumatic-material line 8, with the help of which they are loaded into a vehicle (not shown) delivering the grain mass with

5 unground seeds per hospital. At the hospital, the ear part is processed and domolchivat. It is possible to dry both the ear part before the domolot and the stem part. Stationary products are served to sites.

Claims (2)

1. A method of harvesting grain crops, 5 including cutting plants with a header, chopping the cut mass and delivering it to the hospital for further processing, characterized in that, in order to reduce the damage to the grain and the energy intensity of the chopping, 0 is delivered in an unmilled form, and the stems of plants on the header are crushed. 2. A grain harvesting device containing a header with a cross conveyor and an unloading window, a feeding conveyor and a chopping mechanism with a horizontal knife rotor, characterized in that the chopping mechanism is installed in the unloading window and provided with two horizontal shafts arranged one above the other in front of the knife rotor with mounted on them supporting discs with exciting fingers, with the rotor blades placed between the discs and mounted on the front and middle relative to the direction of movement device parts of the rotor to prevent chopping the spike part of the cut mass.
