Abstract

A device for spilling grain in a grain elevator, equipped with a central grain chute and centrally suspended thermometric probe, characterized in that it has four interconnected conical funnels (1-4) and they are situated coaxially in relation to the thermometric probe (7), whereas in the upper part of the device a collecting funnel (2) is placed, inside of which a smaller collecting funnel is mounted (1) and the above-mentioned funnels are directed downward with their smaller bases, whereas under the funnels (1) and (2) a spread funnel is mounted (3) which in its upper part has a smaller base edge and to that edge a bigger edge of the spread funnel is fixed (4) which is placed inside the funnel (3) and is directed with its smaller base downward.<IMAGE>

Description

The subject of the invention is a device for spreading grain in a silo having a centrally suspended thermometric probe.

There are known gravity grain spreading devices in silos having a funnel-shaped housing in which a roller is placed with a two-armed chute ending with guides attached to it.

Spreading devices are also known which have a funnel-shaped housing to which is attached an electric motor driving a rotating shaft, at the end of which is a two-arm inclined or horizontal chute.

Other known devices are single spreading cones mounted under a charging pipe in a silo.

The device for spreading grain in the silo according to the invention is characterized in that it has four conical funnels connected to each other and coaxial with the thermometric probe, the collecting funnel located in the upper part of the device, inside which a smaller collecting funnel is mounted. Said funnels are directed downwards by their smaller bases. Under the mentioned funnels is mounted a scattering funnel having a smaller base edge in the upper level, to the edge of which is attached the larger base edge of the scattering funnel pointing downwards with the smaller base and located inside the previous scattering funnel.

A handle is attached to the collecting hoppers in the upper part of the apparatus, which on the other side is attached to the central grain hopper, the opening angle of the smaller collecting hopper preferably being smaller than the opening angle of the larger collecting hopper.

The advantage of the device for spreading grain in the silo according to the invention is the effective pouring of an even layer of grain, also in the case of eccentric pouring of grain into conical hoppers.

The advantage of the device is also the possibility of its use in silos with a centrally suspended thermometric probe.

The device is relatively simple in structure and prevents the self-segregation of grain.

The subject of the invention is shown in the embodiment on the drawing, which shows a diagram of a device mounted in a silo.

The silo has a central 6 grain hopper and a central thermometric probe 7.

The device is constructed of a conical smaller collecting funnel 1 fixed in a conical larger collecting funnel 2, the opening angle of the funnel 1 preferably being smaller than the opening angle of the collecting funnel 2. These funnels have their smaller bases directed downwards and are situated in the upper part of the device. In the lower part of the device there is a conical scattering funnel 3 attached to the funnel 2 via a catch. The funnel 3 points with the smaller base upwards. Attached to the upper edge of the funnel 3 is the edge of the larger base of the conical scattering funnel 4, placed in the funnel 3. The funnel 4 is directed downwards with the smaller base. The hoppers 1 t are connected to each other and positioned coaxially with respect to the probe 7. The hopper 2 is attached to the central grain hopper 6 via a handle 5.
