Abstract

FIELD: agriculture.

SUBSTANCE: device for loading and treatment of grain comprises a frame provided with wheels, on top of which there are in one plane three casing with circular cross section with conveying working bodies made in the form of spiral screws. At that each working body is fixed on one side on a metal cylinder which is secured by bolting through the radial opening in it to the drive shaft, which is arranged with adjustable rotational rate. In the lower half of the casing there are windows closed by lids, inside the lids the sprayers are mounted made in the form of centrifugal atomisers, and the upper ends of the casings are provided with unloading windows. The working bodies at their lower parts are made protruding beyond the outer edges of the casings and provided with protective grids made of metal round rod and fastened with welding joint, and the drive of the working bodies is made common from the electric motor through the V-belt drive. On the frame a tank with the seed treatment fluid is mounted, which is connected to the atomisers by the pipeline.

EFFECT: reduce of manual labour in the process of operation, increase of productivity and changing quality for the better the quality of the finished product.

Description

The invention relates to agricultural machinery, in particular to a device for dressing grain.

Known seed dresser [Patent RU 96453, publ. 08/10/2010, Bull. No. 13], comprising a seed hopper with a dispenser, a transporting working body mounted in a casing made in the form of a flexible spiral screw, a sprayer, a dispensing device and a transporting working body drive made with an adjustable speed, the casing is equipped with a mechanism for adjusting its angle of inclination, which includes hinge and adjusting screw, in the lower half of the casing in its upper part there is a window closed with an airtight cover concave outward, a sprayer made in the form of a centrifugal shape is installed inside the cover Unki and the upper end of the housing is provided with unloading window.

Known seed dresser has disadvantages, which include manual labor when feeding grain to the loading hopper, low throughput and unstable fastening of the working body.

The purpose of the invention is the reduction of manual labor in the process, increasing throughput and improving the fastening of the working body.

The goal is achieved by the fact that the device is performed with three working bodies installed in parallel in the same plane and placed in circular casings. The working bodies from their lower part are performed protruding beyond the outer edges of the casings and are equipped with protective grilles made of a round metal bar and fastened with a weld. Three sprayers are installed at the same level from above along the axis of the working bodies, soldering them into the covers mounted on the casings. The drive of the working bodies is performed common from the electric motor through a V-belt drive. Moreover, each working body is fixed on one side to a metal cylinder, which is fastened through a radial hole in it to a drive shaft with a pulley mounted on it.

The technical result achieved is the optimal operation of all three working bodies, automatic grain sampling and its movement along the casing to the unloading window, a significant increase in throughput, as well as high-quality atomization of the reagents by nozzles and increased usability.

In FIG. 1 shows a general view of the device, FIG. 2 - the same, top view.

A device for loading and dressing grain consists of a frame 1 equipped with wheels 2, on top of which are three casing of circular cross section 3 with transporting working bodies 4 in the form of spiral screws. Moreover, each working body 4 is fixed on one side to a metal cylinder 14, which is bolted through a radial hole in it and mounted on the drive shaft 15. The drive 5 of the working bodies 4 is made with an adjustable speed. In the lower half of the casings 3 there are windows closed with outwardly concave covers 6, atomizers 7 made in the form of centrifugal nozzles are installed inside the covers, and the upper ends of the casings 3 are equipped with unloading windows 8. The device is made with working bodies 4 installed in parallel in the same plane as spiral screws, and in their lower part are made protruding beyond the outer edges of the housings 3 and are equipped with protective grilles 9, and the drive 5 of the working bodies is made common.

A tank 10 with etching liquid is mounted on the frame 1, which is connected to the nozzles 7 by a pipe 11. A liquid treatant is supplied from the tank 10 to the nozzles 7 by means of a pump 12 mounted on the frame 1 through the metering valve 13.

A device for loading and dressing grain works as follows. The drive 5 is turned on, which drives the flexible spiral screws 4 located in the casings of circular cross sections 3.

The device is rolled up to the embankment of grain so that the working bodies 4 are completely immersed in the grain. An electric motor 5 is turned on, which drives the working bodies 4 by means of a V-belt transmission. Next, turn on the pump 12, rotate the metering valve 13 by a predetermined angle, as a result of which the etching liquid from the tank 10 enters the casings 3 through the pipe 11 and is sprayed by the spray guns 7 inside the chambers, closed by outwardly sealed caps 6.

The working bodies 4 move and intensively mix the grain material with the pickling liquid and remove it from the device through the discharge windows 8.

The presence of several helically helical working bodies can increase throughput and reduce the complexity of etching, as well as reduce manual labor. In this case, the working bodies are attached on one side to a metal cylinder, which is bolted through a radial hole in it and mounted on the drive shaft.
