Abstract

Usage: unloading bulk materials from containers, mainly from dryers. SUMMARY OF THE INVENTION: the device comprises a support structure with rails, a cantilever frame mounted in rails with the possibility of longitudinal movement and having a working member in the form of a chain with scrapers and a drive. The rails are rotatably mounted in a vertical plane, and are provided with screws for adjusting the angle of rotation. 2 ill.

Description

The invention relates to agricultural machinery and can be used on mechanized drying points of flaxseed and rotary grain dryers.

The purpose of the invention is to increase the reliability of the device.

Figure 1 shows a discharge device, side view; figure 2 is the same, a section along the axis of the horizontal hinge.

The device comprises a support structure 1 with guides 2. which are mounted on it by means of a horizontal hinge 3 and adjusting screws 4, as well as a cantilever frame 5 mounted in the guides 2 with the possibility of longitudinal movement on the roller bearings 6. The cantilever frame has a working body 7 in in the form of a chain with scrapers, a dividing plate 8, a protective casing 9, enclosing the idle chain branch, the drive 10 of the working body. The drive 11 for longitudinal movement of the cantilever frame 5 serves to enter it (output) into the drying chamber 13 through the discharge window 12. The axis

the hinge 3 is located in the middle of the window 12 for unloading dry material.

A belt conveyor 14 is located under the device for discharging dry material.

The device operates as follows.

When the flaxseed (grain) in the lower part of the drying chamber 13 reaches a conditioned humidity, proceed to its unloading. To do this, open the window shutter 12, turn on the drive 10 of the chain working member 7, after which the cantilever frame 5 with the working body begins to be gradually introduced, on the roller bearings 6, into the dried material in the chamber 13,

Previously or during the entry process of the cantilever frame 5 with the working body 7 into the material layer, its end is lifted - by turning the guides 2 in a vertical plane around the horizontal hinge 3 using screws 4. The larger the layer of material in the dryer, the greater the angle of rotation of the guide 2. After that, when the working body 7 is operating, the cantilever frame 5 is finally brought into

dryer 11. As soon as the drive switch 11 is turned off, the rotation drive of the drying chamber is turned on and the material enters the discharge zone.

Moving scrapers of the working body 7 destroy the lower dry layer of flaxseed (grain) and transport the torn particles through the window 12 to the conveyor 14. For the razfuzochny device in the drying chamber 13, the layer of flaxseed (grain) is lowered to the thickness of the unloaded dry layer, therefore, the chamber is reloaded with wet material on top.

The separation plate 8 is mounted on the cantilever frame 5 only when unloading bulk materials (e.g. grains) and is designed to separate the lower dry layers from the upper raw ones so that they do not fall into the area affected by the scrapers.

A protective casing 9, mounted on the frame 5, above the idle branch of the working body 7 eliminates the ingress of material, since: firstly, the working branch has already unloaded dry material, and wet layers remain above the idle; and secondly, the idler stays in the opposite direction from the discharge window 12 (to the center of the drying chamber 13).

Due to the fact that the end of the cantilever frame 5 is raised, it can absorb a significantly greater vertical load from the upper wet layers of the material, within its elastic deformation, which eliminates the scraping of scrapers over the perforated bottom of the drying chamber, and therefore ensures reliable operation of the dryer as a whole and unloading device in particular.

In order to ensure reliable unloading of material through the window 12, the axis of the horizontal hinge 3 is positioned at the level of the middle part of this window both in height and in depth, and it is perpendicular to the longitudinal axis of the guides. When using the proposed technical solution for unloading the dried material from the drying chambers,

reliable operation of the device and the dryer is ensured, its downtime is sharply reduced, which ultimately shortens the cleaning time.
