(57) Abstract:The invention is used in the agricultural industry, in particular relates to metering apparatus of belt type. Metering apparatus comprises a hopper for seeds with agitator, damper, the seed chamber, a conveyor belt with a spoon grips, ductus deferens, driving and driven rollers. Moreover, the leading roller covered by fixed guards. When using the apparatus improves the quality of the selection of seeds and reduced the number of injured seeds. 2 Il. The invention relates to the agricultural industry, in particular the metering apparatus of belt type.Similar devices that can be selected seeds, presented in the patent Germany, N 1211014, class A 01 C 7/16, 1987 (analogues). These devices have as the working elements of the belt conveyors.The disadvantage of analog is not sufficiently accurate and stable selection of seeds, and therefore, due to their design, the device is not capable of providing high quality seed.The prototype of this device is the design (see ed. mon. N 1457835, class A 01 C 7/16, 1989), consisting of a hopper woro the s of movement of the conveyor at an angle, equal to the angle of rise of the last, pillows beneath the nests, master, slave and pulleys, black Guillemot seeds.The disadvantage of the prototype is that this design does not provide an accurate selection of seeds, as numerous studies have shown that part of the cylindrical sockets passing through the mass of seeds, not filled with the last, which leads to gaps in the capture of seeds and poor quality of selection. In addition, the establishment of an elastic belt with cylindrical holes (sockets) that the process must preserve the exact position of the centerline of the holes should be tilted at an angle equal to the angle of incline protractor) represents a technical challenge.An object of the invention is the provision of a more uniform selection of seeds in comparison with the prototype, reducing the number of injured seeds, as well as simplifying the design.The technical problem is achieved by seeding unit containing hopper for seeds with agitator, damper, the seed chamber, a conveyor belt with hooks seeds, driving and driven rollers, where according to the invention installed on the transport tape grips for seeds in them getting seeds from the seed chamber between the transport belt and a driving roller.Unlike the prototype of the proposed design is to establish on the surface of the transport belt spoon grabs seeds who scoop the seeds from the seed chamber.And the fact that the leading roller, resulting in movement of the transport tape, covered the two stationary guards for preventing seeds from the seed chamber between the transport belt and a driving roller.The originality of the invention lies in the fact that due to installed on the working branch of the transport tape spoon grabs seeds increases the uniformity of their selection of the seed chamber, as all spoon grips are filled with seeds and no gaps in the capture, in addition, fixed guards, covering rotating the leading roller, prevents the seeds between the leading roller and the transport belt, which protects the seeds from mechanical damage.In Fig. 1 shows a metering unit, side view.In Fig. 2 shows a section along a-a in Fig. 1.The invention consists of a hopper 1 for seeds with agitator 2, valve 3, the seed chamber 4, the transport belt 5, the working branch 6 of the transport belt as surface of the transport belt 5, spoon the clamps 7, is attached to the transport belt 5, the lead 8 and the slave (stretch) 9 rollers, a stationary protective cover 10 covering the leading roller 8 and the tape 5, as well as the VAS deferens 11.The device operates as follows: seeds, mixed in the hopper 1, with agitators 2 go under the flap 3 in the seed chamber 4 where they wyczerpywania Cup grippers 7, located on the conveyor 5. Extra seeds slide down the working branch 6 of the transport belt 5 back into the seed chamber, as the latter is installed in compliance with the conditions
where is the angle of the working branch 6 of the transport belt 5 with respect to the horizontal axis of the device;
the friction angle of the seeds on the surface of the tape 5.The agitator 2 intensively mixes the seeds in the hopper and directs the seeds in the seed chamber 4. The number of seeds in the seed chamber can be controlled via the valve 3. The transfer belt 5 is driven by the leading roller 8, which in turn is driven from the ground wheels of the planter (not shown). The leading roller 8 with the tape 5 is covered on both sides of the static protective casings 10, which prevents the seeds between Lento working branch 6 of the transport belt 5 and is discharged into the ductus 11 and the vomer.Metering system in comparison with the prototype and other structures characterized by its simplicity, reliability, selection of seeds and versatility, this is achieved through the use of a removable Cup gripper, which allows to use the row machine for planting seeds of various crops. The seeding rate can be adjusted by the number of spoon hooks on the transport tape and a change of frequency of rotation of a driving roller.The use of the invention will significantly improve the quality of the seed selection through the use of spoon grips, and also to simplify the design, reduce the number of injured seeds and increase productivity seeding apparatus of belt type. Metering unit containing hopper for seeds with agitator, damper, the seed chamber, a conveyor belt with hooks seeds, driving and driven rollers, characterized in that the grippers for seeds that are installed on the transport belt in the form of spoons, with leading movie covered the two stationary guards for preventing seeds from the seed chamber between the transport belt and a driving roller.
