Description

The utility model relates to agricultural engineering, in particular to sowing machines for sowing machines.

A sowing machine is known (see utility model patent of the Russian Federation No. 191545. - Published on August 12, 2019, Bull. No. 23), consisting of a round section body, on which a loading hopper with a lid is installed on top and with a seed dispenser in its lower part, which is fixed with a bolt. Inside the housing, a working body is installed, made in the form of a spiral screw with the possibility of rotation around its axis, which distributes the seed material in a single layer. By means of a bolted connection, the working body, on the one hand, is attached to the drive round disk, pressing one of its turns. In this case, the disk is made with a splined shaft for connection with the coupling. On the other hand, the helical screw is fixed on a shaft with a bearing, which is fixed on a quick release cover. The disk is driven by a shaft from a drive device. Inside the working body, a round tube made of metal or hard plastic is fixedly installed. The working body is installed with a step suitable for the size of the seeds, and with a gap between the body, the turns of the spiral screw and the inner tube not exceeding the minimum dimensions of the seeds, in order to avoid pinching them. An exit window is made on the lower side of the housing, to which a flexible tube is attached for direct delivery of seeds to the soil.

The well-known sowing apparatus has a disadvantage, which includes the uneven application of seeds during sowing.

Known, adopted as a prototype seeding machine for precision seeding (see utility model patent of the Russian Federation No. 196918. - Published on March 19, 2020, Bull. No. 8), including a housing made of a circular cross section of metal or hard plastic, a boot is installed on top hopper with a lid and with a seed dispenser in its lower part, inside the body there is a working body made in the form of a two-way spiral screw, attached on one side to the drive round disk by means of a bolted connection, pressing one turn of the spiral screw, while the disk is made with a shaft with splines for connection with a coupling, on the other hand, a two-way spiral screw is mounted on a shaft with a bearing, which are attached to a quick-release cover, and a round tube made of metal or hard plastic is fixed inside the working body, and the working body is installed with a pitch suitable for the size of the seeds, and with a gap between the inner surface of the body, the turns of the spiral and the inner tube, not exceeding m is the minimum size of seeds, and on the lower side of the body there is an exit window, on which a flexible tube is attached for direct delivery of seeds to the soil.

A disadvantage of the known device is damage and, as a result, low germination of seeds as a result of their pinching between the double-threaded spiral screw and the round inner tube and dragging them along its surface, as well as uneven seeding, since the coils of the spiral screw periodically pass over the exit window, under which a flexible tube for direct delivery of seeds to the soil, reducing its cross section.

The task that the utility model solves is to reduce damage and, as a result, increase the germination of seeds, as well as increase the uniformity of their sowing in order to increase crop yields.

The problem is solved with the help of a sowing machine for precise sowing of seeds, containing a body made of a circular cross section of metal, a loading hopper with a lid and a seed dispenser in its lower part is installed on top of it, a working body is installed inside the body, made in the form of a two-way spiral screw, attached on one side to the drive round disk by means of a bolted connection, pressing one turn of the helical screw, while the disk is made with a shaft with splines for connection with the coupling, on the other hand, the two-start helical screw is fixed on the shaft with the bearing, which are attached to the quick-release cover, and a round metal tube is installed inside the working body, an exit window to which a flexible tube is attached for direct delivery of seeds to the soil, where the working body in the form of a two-way spiral screw is fixed on a round metal tube installed inside it and is made of wire with a diameter of 4 mm, and also set in increments between soce daily turns of spirals not less than the maximum size of seeds, and the exit window is made in the lower part of the quick-release cover from its outer side.

The utility model is illustrated by the drawing, where in Fig. 1 shows a schematic diagram of a seed meter for precision seeding.

The sowing machine for precise sowing of seeds consists of a body of circular section 8, made of metal, on which a loading hopper 2 with a cover 1 and with a seed dispenser 3 in its lower part is installed on top, which is fixed with a bolt 4. Inside the body 8, a working body 10 is installed, made in the form of a two-start spiral with the possibility of rotation around its axis, which distributes the seed material 9 in two single layers. The working body 10 is fixed on a round metal tube 7 installed inside it.

By means of a bolted connection 11, the working body 10, together with the round tube 7, is attached on the one side to the drive round disk 6, pressing one of its turns. In this case, the disk 6 is made with a splined shaft for connection with the coupling 15. On the other hand, a two-way spiral together with a round tube 7 is fixed on a shaft with a bearing, which are fixed on a quick-release cover 16. The disk 6 is driven by a shaft 12 from the drive device. 5. The working body 10 is made of wire with a diameter of 4 mm, and is also installed with a step between adjacent turns of spirals not less than the maximum size of the seeds in order to avoid pinching them. In the lower part of the quick-release cover 16, on its outer side, there is an exit window 14, to which a flexible tube 13 is attached for direct delivery of seeds to the soil.

Seeding apparatus for precision seeding works as follows.

When the dispenser 3 is closed, the seeds are fed into the hopper 2, then the working body 10 is brought into rotation by means of the drive device 5 and the shaft 12 with the disk 6, respectively. Then the dispenser 3 is moved to a predetermined distance depending on the size of the seeds, and fixed with a bolt 4. The seeds enter the housing 8, where they are captured by the turns of the two-way working body 10 and move towards the exit window 14. In this case, the seeds are jammed between the two-way working body 10 and the internal round tube 7 and dragging them along its surface is excluded, sowing uniformity increases, because the turns of the spirals periodically do not partially cover the exit window 14.

The use of the claimed spiral-screw working body makes it possible to achieve a reduction in damage and, as a result, an increase in the germination of seeds, as well as an increase in the uniformity of their sowing in order to increase crop yields.
