Abstract

A piece dispenser consisting of a body in which a drive shaft with a rigidly attached disk is installed with the possibility of rotation of a drive shaft with a disk in the body, characterized in that spoons preliminarily pressed against it are installed around the circumference of the disk, made in the shape of intended for sowing seeds with the possibility - rotational movement relative to the radial direction, which, when the emphasis runs on the sector rigidly attached to the body, ensure the filling of the limited space between the spoon and the disc with seeds, while in order to ensure the jam of the seed in the limited space between the spoon and the disc and transport the seed to the unloading point, the spoon stop is provided from the sector, while the moment of unloading is provided when the stop runs against the ejector stationary on the body, in addition, a feeder is rigidly attached to the body, intended for supplying seeds, and a storage device intended for dropping seeds entrained centrifugal force into the feeder.

Description

The utility model relates to agricultural machinery, in particular to devices for piece planting.

A tool for introducing bulk materials into the soil is known, including a frame with running wheels on which a metering device in the form of a drum is freely mounted on an axis. Holes are made in the rim of the drum with pivotally mounted spring-loaded buckets-dumpers having stops. A disk with a bracket and a roller is mounted on the drum axis, interacting with the stops of the dumping buckets [SU 1014496 A, A01C 7/14, A01C 15/16, 08/13/1981]. The proposed device does not provide for regulation of the seeding rate of the introduced material, in addition, it is difficult to manufacture.

A sowing unit is known for a sowing unit, comprising a hopper and a vertical sowing disk mounted beneath it with cells around the circumference, at the ends of which are installed an elastic shut-off device and a support plate made in the form of disks with holes, the support plate being fixed to the disk shaft rigidly from the side opposite to the hopper [SU 1183012 A1, A01C 7/04, 10/07/1985].

However, this sowing apparatus has insufficient accuracy of sowing due to missed seeds in the corresponding cells as a result of caking and clogging of the space under the cells. In addition, due to the constant friction of the rotating disk with seeds, the latter are injured.

A sowing unit is known for a sowing unit, comprising a hopper and a vertical sowing disk mounted beneath it with cells around the circumference, at the ends of which are installed an elastic shut-off device and a support plate made in the form of disks with holes, the support plate being fixed to the disk shaft rigidly from the side opposite to the hopper , the sowing device is equipped with an air supply leading to the exhaust gases from the tractor connected to the cutter openings communicating through disc cells with openings on support plate, which are connected to the seed vault of the coulter, while the cells on the disk are made at an angle to its rim, the hopper is divided by a partition into two sections, which are equipped with tedders sitting on the same shaft driven by the seed disc shaft, but having a rotational speed greater than the shaft speed disk, and on the last there are additional cells for mineral fertilizers, moreover, cells for seeds of the sowing disk are located under the section of the hopper with seeds, and cells of the cutter are located under the section of the hopper with convenient rhenium, the cutter and the supporting plate are equipped with springs and clamps. [RU 2081543 C1, 6 A01C 7/04, 06/20/1997]. However, this metering apparatus has a design complexity.

In case of piece planting, there is a significant difference in the speed of the unit and the initial flight speed of the seed. Since the initial speed of the sowing material is directed in the opposite direction of the movement of the aggregate and it is smaller in absolute value, rolling of the sown material after the aggregate is observed on the bed prepared by the coulter, which in turn leads to uneven sowing along the length of the row and, as a result, a decrease in yield.

In order to increase the uniformity of sowing seeds, the task is to increase the maximum peripheral filling rate due to lateral filling of the cells.

To accomplish this task, a piece dispenser has been developed, which consists of a housing 1, in which a drive shaft 2 with a rigidly mounted disk 3 is installed, with the possibility of rotation of the drive shaft 2 with a disk 3 in the housing 1. Around the circumference of the disk 3 are spoons 4, previously pressed to the disk 3 by any known method (for example, using a spring, not shown) with the possibility of a reciprocating motion relative to the radial direction, and stops 5 are made on the spoons 4. A feeder 6, a drive 7 are rigidly attached to the housing 1, ejector 8 and sector 9.

Piece dispenser works as follows. Seeds fall into the feeder 6 of a piece dispenser. When the drive shaft 2 rotates with the disk 3, when the spoon 4, pre-pressed against the disk 3, runs against the sector 9 with emphasis 5, the spoon rotates relative to the radial direction and forms a place for one seed in a limited space between spoon 4 and disk 3. When filling a limited space with seed , and further rotation of the disk 3, the spoon 4 leaves the sector 9 and sticks the seed in a limited space between the spoon 4 and the disk 3. With a further rotation of the disk 3, the seeds are transported to the place of unloading pinched between 4 spoons and a disk 3. Unloading of seeds occurs in the lower part of the housing 1 by running the stop 5 located on the spoon 4 on a motionless ejector 8 located on the housing 1. The shape of the spoon determines the shape of the seeds sown.

At increased peripheral speeds of rotation of the disk 3, seeds, carried away by centrifugal force, will be discharged into the accumulator 7 and again enter the feeder 6.

The proposed device for sowing will provide a uniform distribution of seeds along the row, which will increase the yield.
