Description

Изобрете 1ие относитс к устройствам дл добычи торфа фрезерным способом, главным образом, на залежах с высокой степенью разложени или высокодиспергированными торфами.The invention 1 relates to devices for the extraction of peat by a milling method, mainly in deposits with a high degree of decomposition or highly dispersed peat.

Известны устройства дл фрезеровани торф ных залежей, используемые при добыче .торфа, выполненные в аиле цилиндрического корпуса с режущими элементами в виде конических штифтов или тарельчатых ножей 1 ,There are known devices for milling peat deposits used in the extraction of peat, made in the ail of a cylindrical body with cutting elements in the form of conical pins or disc-shaped knives 1,

Недостатком таких устройств вл етс то, что получаемый фрезерный торф иеоднороден по фракционному составу.The disadvantage of such devices is that the milled peat obtained is not homogeneous in terms of fractional composition.

Известно также устройство дл фрезеропани торф ной залежи, включающее раму , цилин/орический корпус с отверсти ми в ножи .It is also known a device for milling a peat deposit, comprising a frame, a cylin / oriental body with openings in the blades.

Однако и этой конструкции присущ вышуказанный недостаток.However, this design is inherent in the above drawback.

Цель изобретени - создание оптимальных условий . сушки и повышение сезонного сбора торфа.The purpose of the invention is to create optimal conditions. drying and increasing seasonal collection of peat.

Это достигаетс тем, что рама предлагаемого устройства снабжена ..очистителем и осью, котора смещена эксцентрично относительно продольной оси цилиндрического корпуса и соединена с ножами с помощью шарнирных т г, а ножи расположены в отверсти х корпуса.This is achieved by the fact that the frame of the device proposed is equipped with a cleaner and an axis that is eccentrically displaced relative to the longitudinal axis of the cylindrical body and connected to the blades by means of hinges and the blades are located in the openings of the housing.

На фиг. 1 схематически изображено предлагаемое устройство; на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 schematically shows the proposed device; in fig. 2 shows section A-A in FIG. one.

Фрезерующее устройство имеет вид цилиндрического корпуса 1 с проходными радиальными каналами 2, закрепленного на подшипниковых опорах 3 рамы устройства 4. Вращение цилиндрического корпуса осуществл етс с помощью приводного колеса 5. В полости корпуса с эксцентриситетом i , расположенным ниже оси корпуса, установлена ось 6, неподвижно закрепленна концами в раме устройства.The milling device has the form of a cylindrical body 1 with radial passageways 2 fixed to the bearing supports 3 of the frame of the device 4. Rotation of the cylindrical body is carried out using a drive wheel 5. In the housing cavity with eccentricity i located below the axis of the body, the axis 6 is fixed fixed ends in the frame of the device.

Claims

On the axis, by means of hinged bolts, g 7 are fixed knives 8, placed and freely moving in the radial knots of the cylindrical body. To remove peat sticking to the drum surface, a scraper 9 is installed on the frame, which contacts the surface of the upper half of the cylindrical body, i.e. outside the knives' mixing zone above the surface of the cylindrical body. When rotating the tsipindricheskoy of the housing 1, the blades 8, which are located in the radial channels 2, rotate about a fixed axis 6, eccentrically set relative to the axis of the housing. At the same time, the axis 6 is set so that the knives 8 connected to it with the help of hinged joints 7 extend from the radial channels above the surface of the lower half of the rotating cylindrical body and at the point of contact of the cylindrical body and cut it to a depth corresponding to knife exit above the surface of the body. As the knives move in. the upper part of the rotating drum they retract into its cavity. The peat on the mass on the surface of the cylindrical body is placed in front of the knife. It can be cleaned 9. Running a milling drum with knives periodically retracting into its strips allows the puller to be installed on the peat drum and making it workable when milling highly dispersed peat and such. Tzalzhey with a high degree of dilution at a relatively low surface speed. In addition, a reduction in the working speeds of milling will provide an organized spreading layer with the most favorable conditions of the next drying process and will significantly reduce energy costs. Apparatus of the Invention A device for milling a peat deposit, comprising a frame, a cylindrical body with openings and tla and so that, in order to create optimum conditions of flow and increase the seasonal collection of peat, the frame is equipped with a cleaner and an axis that is eccentrically mixed relative to the longitudinal the axes of the cylindrical body and are connected to the blades by means of hinge rods, and the blades are located in the openings of the body.
