Abstract

The utility model relates to the field of agriculture and can be used for preliminary drying of flaxseed when harvesting in high humidity with a combine harvester. The proposed utility model is intended for drying flaxseed by supplying a drying agent to the bunker of a combine harvester in order to better distinguish flax seeds from the flax harvester during the operation of the flax harvester . As the drying agent, air is used, heated in the recuperative heat exchangers by the heat of the coolant, engine oil and exhaust gases of the engine. The drying agent leaving the recuperative heat exchangers of the cooling system, lubricants and exhaust gases of the combine engine is fed by the fan through the channels to the bunker of the combine harvester, where it is saturated moisture from flax and is removed from the hopper.

Description

The utility model relates to the field of agriculture and can be used for preliminary drying of flaxseed during harvesting in high humidity conditions with a combine harvester.

A device for flax harvester [patent SU 1052190, authors Bykov NN, Kovalev MM, Ognev EM, and others; bull. No. 41 dated November 7, 83], containing two front-facing haul-off machines, symmetrically longitudinal and clamping conveyors located behind them, combing chambers with drums and a hopper for heap, in which to increase the reliability of the process during transportation of the heap into the hopper and simplify the design, the axes of the pulleys of the clamping conveyors are installed horizontally, and the stripping drums are located on the lateral outer sides of the clamping conveyors, and the cleaning chambers communicate with the upper front part of the hopper m smoothly curved channels.

The disadvantage of this device is the insufficient quality of stripping of the wet mass of flax stems supplied by longitudinal conveyors to the stripping chamber, and the insufficient separation of flax and flaxseed due to their increased humidity.

A device for a flax harvester [patent 173419, authors Gaididei S.V., Zefirov I.V., Kuznetsova N.I., Martynov P.S., Orobinsky D.F., bull. No. 25 dated 08/28/2017], taken as a prototype, containing two front haul-off machines, symmetrically longitudinal and clamping conveyors located behind them, combing chambers and a bunker for a heap, while for preliminary drying of the stalks of flax to the longitudinal conveyors through the perforated channels, a dryer is fed with a fan agent heated in installed recuperative heat exchangers of the cooling system, lubrication and exhaust gases of the combine engine.

The disadvantage of this device is the insufficient drying of flaxseed, since the bulk of the heat of the engine is spent on drying flaxseed.

The objective of the proposed utility model is to use the engine heat of the flax harvester to dry the flax heap in the bunker of the harvester after combing the flax stalks.

The proposed utility model is intended for drying flaxseed with a drying agent supplied to the flaxseed hopper during operation of the flax harvester. The air used in the regenerative heat exchangers of the cooling system, lubrication and exhaust gases of the combine engine is used as a drying agent.

The technical result of the proposed utility model is the drying of flaxseed directly in the bunker of the combine, which is especially valuable when harvesting flax with high humidity flax.

The essence of the proposed device is to supply a drying agent to the flax harvester hopper — air, which is heated in the recuperative heat exchangers of the cooling system, lubrication and exhaust gases of the combine engine.

The figure shows a diagram of a device

A flax harvester consists of two front pulling machines 1, symmetrical longitudinal conveyors 2, clamping conveyors 3, combing chambers 4, a hopper 5 for a heap, recuperative heat exchangers 6 with a fan installed with the possibility of supplying a drying agent through perforated channels 7 to the hopper for drying. All working bodies of the harvester receive a drive from the engine 8.

The implementation of the utility model is as follows.

During the movement of the flax harvester, the stalks of flax come to two front haul-off machines 1. The stalks that have been removed are fed to the longitudinal conveyors 2, which move the stalks to the clamping conveyors 3. Then, the stems clamped in the clamping conveyors 3 are combed in the combing chamber 4. The resulting heap under the influence of air flow enters the hopper 5, where the drying agent is fed through perforated channels 7 from regenerative heat exchangers 6 of the cooling system, lubrication and exhaust gases of the engine 8 combine but. In the hopper 5, the drying agent is saturated with moisture from the flaxseed and removed to the outside.

Claims (1)

Flax harvester containing two front haul-off machines, symmetrically longitudinal and clamping conveyors located behind them, stripping chambers and a hopper for heaps, recuperative heat exchangers of the cooling system, lubricants and exhaust gases of the combine engine for heating the drying agent, perforated ducts, a fan installed with the possibility of supply drying agent through perforated channels into the hopper for drying flaxseed.
