The invention relates to techniques for the production of milled peat, namely, bunker peat harvesting machines, providing cleaning due to the impact on peat particles of the stream of air is sucked through the nozzle under pressure.Known nozzle pneumobrakes machine, comprising a body of rectangular cross-section with a visor smoothly acercando ypolnennye in the form of a plate (see A. C. the USSR 877030).The disadvantages of the known device are the low cycle duties because of the dependence of the absorption rate of peat crumb from the movement speed of the machine.The objective of the invention is to increase such fees milled peat.This object is achieved in that the nozzle of the pneumatic corroborates machine, comprising a body of rectangular cross-section with a visor smoothly contoured profile, mounted above the entrance slit, a scraper pivotally attached to the body of the nozzle with tie rods and is made in the form of a plate according to the invention the angle at which the scraper is 18-25owhich is selected from considerations of creating the best conditions for lifting peat raised.The angle of the scraper 18-25ois selected from considerations of the possibility of creating the best conditions for lifting peat raised. A decrease in the angle <18the peat falls under the nozzle, which impedes its absorption, while increasing the angle of >25opeat particles will fly and not fall into the slit nozzle, despite the established canopy.The invention is illustrated by the drawing, which shows a nozzle (side view).
opivotally mounted scraper 4 made in the form of a plate. Scraper 4 pivotally attached to the housing 1 with tie rods 5.The device operates as follows.Together with corroborates machine body 1, the nozzle is moved in the direction indicated by the arrow. Due to rising raised scraper 4 milling baby is in a suspended state and then under the action of the vacuum created by the fan pneumobrakes machine (not shown), tortuously mixture is sucked into the nozzle and then through the duct enters the cyclone corroborates machine, where the selection of peat from the air flow.At clash of the inclined plane of the scraper 4 resting on raised milling chips must take into account the condition of continuity for the moving of the peat layer, which is determined by the ratio of resistance force to the shift of peat in peat and external friction forces FTrmaterial of inclination of the plane. The condition of continuity for the peat layer on the plane of the feasible when the ratio of FTr. It was established that in the process of drying, moisture mill is o.When using this device the speed of the suction tortuously mixture does not depend on speed of movement of corroborates machine.Designed nozzle device can be applied to existing harvesting combines. The nozzle design is simple and can be manufactured in the workshops of peat factories. The nozzle of the pneumatic corroborates machine, comprising a body of rectangular cross-section with a visor smoothly contoured profile, mounted above the entrance slit, a scraper pivotally attached to the body of the nozzle with tie rods and is made in the form of a plate, characterized in that the angle at which the scraper is 18-25owhich is selected from considerations of creating the best conditions for lifting peat raised.

FIELD: open-pit mining for obtaining peat.
SUBSTANCE: method involves prior dewatering peat deposit; serially excavating peat from separate zones for depth equal to peat deposit thickness; installing caisson with watertight walls to isolate zone having volume equal to that of caisson from remainder peat deposit; pumping out water from peat deposit zone isolated by caisson to dewater peat inside caisson; removing peat from caisson along with retaining of cut upper horizontal ground forming layer; taking out caisson from excavated zone and diverting water from adjacent zones to above excavated zone; filling hole created in place of previous caisson location with cut upper horizontal ground-forming layer; reinstalling caisson in adjacent zone and repeating above peat production operations.
EFFECT: increased output due to reduced time of prior peat deposit dewatering, reduced peat drying time due to production of peat mass having lesser moisture content and possibility to maintain natural water balance of surrounding territory.

Platform is made in form of a pontoon and connected by rigid connection to off-road rig, and on it high pressure forcing pump, diesel plant, vacuum pump are mounted and interconnected, and additional pipes are positioned for drilling the well and extending the slurry pipeline. Working organ is provided with peat intake connected to external pipe, which is positioned above the hydro-monitor, and has radially made apertures along whole perimeter with diameter not less than 15 mm, hydro-monitor being made in form of conical tip, perforated across whole surface, with diameter of apertures not more than 3 mm, while external pipe through the vacuum pump is connected to the slurry pipeline.
EFFECT: lowered costs, ensured ecological safety, increased reliability, shorter times needed to launch areas into operation, extended peat extraction season and transition to year-round production.
SUBSTANCE: invention refers to method of excavation of garden or fuel peat. Peat is extracted from a bog, is transported from the bog at a distance to a drying field, whereon transported peat is dried with the use mainly of direct solar energy so, that peat is being dried under influence of solar radiation and wind. When peat is dried, it is transferred from the drying place for further use or storing. The said drying field is made in form of specially leveled field, in essence not permeable to water and accommodated for drying; peat is spread on the field in form of a thin layer of 1-15 cm thickness of high consistent mass with contents of solid substance of 8-30%.
EFFECT: creating method and equipment which facilitate more efficient use of peat bogs with their banks without producing dust, noise and harmful effect to rivers.
