Изобретение относитс к оборудованию лесной промышленности и лесного хоз йства , в частности к устройству дл отделени древесной зелени от срубленных ветвей и деревьев и может быть использовано при производстве хвойно-витаминной муки и технологической щепы дл древесно-стружечного производства.The invention relates to equipment for the forest industry and forestry, in particular, to a device for separating wood greenery from felled branches and trees, and can be used in the production of coniferous-vitamin flour and wood chips for wood-shaving production.

Известно устройство дл отделени древесной зелени, включающее подающий и отвод щий транспортеры, между которыми установлена термокамера с приемным бункером и отдел ющим рабочим органом, выполненным в виде смонтированного внутри термокамеры вращающегос барабана со сплошной и сетчатой част ми 1.A device for separating wood greenery is known, including feed and discharge conveyors, between which a heat chamber is installed with a receiving bin and a separating tool, made in the form of a rotating drum with continuous and mesh parts inside the heat chamber 1.

Недостатком известных устройств вл етс отсутствие органа дл очистки внутренних стенок термокамеры от накапливающейс на них сухой отделенной зелени.A disadvantage of the known devices is the absence of an organ for cleaning the inner walls of the heat chamber from dry separated greenery accumulating on them.

Известно также наиболее близкое по технической сущности и достигаемому эффекту к изобретению устройство дл отделени древесной зелени от срубленных ветвей и деревьев по авт. св. № 518343, включающее подающий транспортер, термокамеру, рабочий орган и приемный бункер, причем рабочий орган смонтирован внутри термокамеры и выполнен в виде приводного барабана с отверсти ми, снабженного лопаст ми,It is also known the closest to the technical essence and the achieved effect to the invention a device for the separation of green wood from felled branches and trees according to ed. St. 518343, including a feed conveyor, a heat chamber, a working body and a receiving bunker, the working body being mounted inside the heat chamber and made in the form of a driving drum with holes provided with blades,

радиально размещенными на его наружной боковой поверхности 2.radially placed on its outer side surface 2.

В этом устройстве на наружной поверхности барабана имеютс л есткие лопасти, однако они также не исключают возможность накапливани зелени на внутренней поверхности термокамеры и последующего ее возгорани , что приводит к необходимости остановки и очистки барабана, приIn this device, there are strong blades on the outer surface of the drum, but they also do not exclude the possibility of accumulation of green on the inner surface of the heat chamber and its subsequent fire, which leads to the need to stop and clean the drum, when

этом зелень пересыхает и тер ет свои ценные качества. Все это приводит к снижению эффективности работы устройства в целом. Цель изобретени - повышение эффективности работы и качества получаемой зелени .this green dries up and loses its valuable qualities. All this leads to a decrease in the efficiency of the device as a whole. The purpose of the invention is to increase the efficiency and quality of the greens produced.

Достигаетс это тем, что лопасти барабана выполнены в виде щеток криволинейной формы с выпуклостью, обращенной навстречу вращени барабана.This is achieved by the fact that the blades of the drum are made in the form of brushes of a curvilinear shape with a convexity facing the rotation of the drum.

На чертеже схематически изображено описываемое устройство дл отделени древесной зелени от срубленных ветвей и деревьев , вид сбоку. Устройство содержит подающий орган 1,The drawing shows schematically the described device for separating the wood green from felled branches and trees, side view. The device contains the feeder body 1,

термокамеру 2 и смонтированный внутри нее рабочий орган в виде приводного барабана 3 со сплошной 4 и сетчатой 5 част ми. На наружной боковой поверхности сетчатой части 5 барабана 3 установлены лопасти,the heat chamber 2 and the working body mounted inside it in the form of a driving drum 3 with continuous 4 and mesh 5 parts. On the outer side surface of the mesh part 5 of the drum 3 mounted blades,

made in the form of brushes 6, having a 3 / curvilinear shape with a bump in, facing the rotation of the drum. The heat chamber 2 is provided in the lower part with a receiving bin 7 for greenery (needles). To supply the coolant to the drum 3, there is a heat pipe 8. The operation of the device for separating greens is carried out as follows. With the help of the feeder body 1, cut branches and trees (small ones) are loaded into the drum 3, and at the same time heat carrier is fed through the heat conductor 8 into the drum. In the STRONG part 4 of the drum 3, the wood green dries, separates and through the holes of the mesh part 5 falls on the inner surface of the heat chamber 2. Due to the presence on the mesh part 5 of the brushes 6 sliding along the inner surface of the heat chamber 2, the green is cleaned into the receiving bin 7. Curvilinear the shape of the brushes 6, with the unwindingness of the rotation of the drum 3, facilitates the movement of the separated green from the peripheral part to the center of the brushes, which makes it possible to concentrate the green above the bunker 7 and eliminate its loss. From bunker 7, greens are processed for processing into vitamin flour. Free from greenery, the crown falls out of drum 3 and is recycled into process chips. The presence of curved brushes 6 on the outer side surface of the mesh part 5 of the drum 3 eliminates sticking, accumulation and ignition of the separated dry greenery on the inner surface of the heat chamber 2. As a result, the quality of the resulting greenery, productivity and overall performance of the device are improved. The invention The device for the separation of green wood from felled branches and trees by author. St. No. 518343, characterized in that, in order to increase the working efficiency and quality of the wood green produced, the edges of the drum are made in the form of curvilinear brushes with a convexity facing the rotation of the drum.
