Description

The claimed utility model relates to agricultural machinery, namely to devices for drying agricultural crops, for example, food and seed grain of cereals, legumes and oilseeds, as well as forage grasses, vegetables and fruits, and can be used in large and small agricultural and grain processing enterprises when preparing grain for storage, as well as at enterprises of the agro-industrial complex.

A plant for drying agricultural crops is known from the prior art, which contains sequentially operating and inclined trays with mesh bottoms, under which a heat carrier is supplied through a distribution channel using a fan, chain conveyors with scrapers for moving material in trays from a loading device to an unloading device and a heat generator with pipelines and diffusers for receiving and supplying a coolant (see USSR Inventor's Certificate No. 149711, M. Cl .: F26D 17/04, publ. 1962) (1). The disadvantage of the known installation (1) should be attributed to stuffing the material between the mesh bottom and the strips of the scraper conveyor during operation, which leads to the need after completion of work or when changing the type of dried agricultural crop, to extract the material manually.

Known conveyor dryer (RU 2650011 C1, publ. 04/06/2018) (2), selected as the closest analogue, which includes a conveyor, over the conveyor along it are sequentially installed fan heaters, on the blades of each of which permanent magnets are rigidly installed ... The dryer can additionally contain at least one additional conveyor with fan heaters installed above them along each of them, permanent magnets are rigidly mounted on the blades of each of them, and the conveyors are installed one above the other with the possibility of transferring the dried product from the upper conveyor to the underlying conveyor. Permanent magnets are placed on opposite sides of the blades symmetrically to each other. At least one conveyor is enclosed in a separate box.

The device (2) indicated as the closest analogue requires large labor costs for cleaning the material remaining in it when changing the type of dried agricultural crop, or after completion of the dryer, since it involves only a manual method of cleaning the conveyor dryer.

The technical result of the claimed utility model is to minimize labor costs for cleaning the dryer from the material remaining in it, when changing the type of dried agricultural crop, or after the completion of the conveyor dryer.

The technical result is achieved by creating a conveyor dryer containing a chain conveyor, a blowing bed, additionally equipped with a cleaning device, which is a removable brush, consisting of a supporting rectangular base, along the perimeter of which there are bristles made of pile, while the device is attached to the conveyor scraper using hardware. At the end of the conveyor dryer or when changing the type of dried agricultural crop, the cleaning device is installed on the conveyor, which is activated. During the movement of the scraper conveyor, the brush of the cleaning device scrapes and moves all the debris along the movement of the scraper conveyor from the blow-out bed and removes it from the dryer.

The claimed utility model is illustrated by the following schematic illustration.

The positions indicated mean the following:

1 - chain conveyor;

2 - purged bed;

3 - cleaning device;

4 - carrying rectangular base of the cleaning device;

5 - bristles made of pile;

6 - scraper;

7 - hardware.

The declared conveyor dryer with the possibility of self-cleaning, contains a chain conveyor 1, a blowing bed 2, is additionally equipped with a cleaning device 3, which is a removable brush, consisting of a supporting rectangular base of the cleaning device 4, along the perimeter of which there are bristles made of pile 5, while the device is attached to scraper 6 of conveyor 1 with hardware 7.

The conveyor dryer operates with the possibility of self-cleaning as follows.

At the end of the conveyor dryer or when changing the type of dried agricultural crop, the cleaning device 3 is installed on the scraper 6 of the conveyor 1 of the conveyor grain dryer with the help of hardware 7 with a brush down. The dryer starts up without loading the crop. The brush of the cleaning device, consisting of a supporting rectangular base 4 and bristles made of pile 5, when moving the conveyor 1, scrapes and moves all the debris along the movement of the conveyor 1 from the blowing bed 2 and takes it out of the dryer.

The use of the claimed device minimizes labor costs for cleaning the conveyor dryer when changing the type of dried agricultural crop, or after the dryer is finished.

Claims (1)

Conveyor dryer containing a chain conveyor, a purge bed, characterized in that it is additionally equipped with a cleaning device, which is a removable brush, consisting of a supporting rectangular base, along the perimeter of which there are bristles made of pile, while the device is attached to the scraper of the conveyor using hardware.
