Description

The invention relates to agricultural machinery, in particular, to seed treaters.

The number of known treaters includes a transporting working body, a feeding device, a seed hopper, a seed dispenser, a working fluid reservoir, a working fluid dispenser, a dressing chamber, a discharge device [1-8].

Seed treaters PS-10A are known, including a frame with wheels, a self-propelled transmission, a refueling pump, a suspension tank, a metering pump, a loading screw conveyor, a seed bunker, a seed feeder, a dressing chamber, mixing and unloading screw conveyors [9, C. 172].

The KLEVER seed treater is also known, which includes a frame, a running gear with wheels and a self-movement mechanism, a scraper type seed loader, a tank for toxic chemicals, a working fluid dispenser, a dressing chamber, an unloading auger [10, p. 27].

The common disadvantages of the listed treaters are the use of mechanical (screw and scraper) transporting and feeding working bodies, which leads to an increase in the energy intensity of the dressing process and damage to the seeds.

The closest adopted for the prototype is a seed dresser containing a frame with wheels, a self-movement mechanism, a loading device, a seed bunker, a pesticide reservoir, a pesticide dispenser, a pickle chamber, an unloading auger [10, p. 23].

The disadvantage of this treater is the high specific energy consumption of the dressing process and the high degree of injury to the seeds by the augers of the loading and unloading devices, which reduces their field germination, respectively, yield.

The objective of the invention is to eliminate these disadvantages.

The technical result of the reduction of injury to seeds and the energy intensity of the process of seed dressing.

This technical result is achieved by the fact that in a seed dressing containing a frame with wheels, a self-movement mechanism, a loading device, a seed bunker, a toxic chemical tank, a toxic chemical dosing unit, an etching chamber, an unloading auger, according to the invention, the loading device is in the form of a hollow pneumatic conveying pipe placed on frame along the longitudinal axis at an angle of 45 °. In this case, the hollow pneumatic conveying pipeline in the upper part smoothly passes into a horizontal position and is hermetically connected to a horizontal inlet nozzle of the discharger of the loading device. Moreover, the discharger loading device is made in the form of an inverted truncated cone with an angle of inclination of the side wall to the horizon of 70 °, the lower output neck of which is tightly connected to the seed hopper and the upper neck to the suction nozzle of the centrifugal fan.

FIG. 1 depicts the proposed seed treater.

The seed treater contains a frame with wheels 1, a self-transfer mechanism 2, a loading device 3, a seed bunker 4, a toxic chemicals tank 5, a toxic chemicals metering unit 6, a dressing chamber 7, an unloading auger 8. At the same time, a loading device 3 to reduce injury to seeds and reduce the energy intensity of the process etching, made in the form of a hollow pneumatic conveying pipe 9, placed on a frame with wheels 1 along the longitudinal axis at an angle of 45 °. Moreover, the hollow pneumatic conveying pipe 9 in the upper part smoothly goes into a horizontal position and is tightly connected to a horizontally located inlet 10 of the unloader 11 of the loading device 3. The discharger 11 of the loading device 3 is made in the form of an inverted truncated cone with an angle of inclination of the side wall to the horizon of 70 °, the lower the output neck 12 of which is hermetically connected to the seed hopper 4, and the upper neck 13 - with the suction nozzle 14 of the centrifugal fan 15. The angle of inclination of the wall pa gruzitelya the horizon 70 ° provides bezzatornoe delivery seed hopper 4.

The device works as follows.

When turning on the centrifugal fan 15 in the discharger 11 and the hollow pneumatic transport pipe 9, a vacuum occurs, due to which the seeds from the collar 16 are sucked into the hollow pneumatic transport pipe 9 and the air-grain mixture is transported to the discharger 11. Use in the loader 3 hollow pneumatic transport pipe 9 instead of rotating auger working bodies reduces trauma to the seeds and the energy intensity of the dressing process. The placement of the hollow pneumatic conveying pipe 9 at an angle of 45 ° also partially reduces the energy intensity of the seed dressing process. In the discharger 11 under the action of gravity, the seeds are separated from the air flow and through the lower outlet neck 12 of the discharger 11 enter the seed hopper 4, and the air flow is blown into the environment by a centrifugal fan 15. The implementation of the discharger 11 in the form of an inverted truncated cone with an angle of 70 ° provides a seedless flow into the hopper 4.

The use of the invention allows to reduce the trauma of seeds and the energy intensity of the process of seed dressing.
