The specified device does not provide the necessary strength of peat briquettes and does not provide accurate dosing of the original material. ,.

A device is known for briquetting; TQ of fuel materials, including a matrix channel connected through a pressing chamber to a loading chamber, a sub-spreader with a plunger having a drive and a stamp connected by a crank-11 mechanism with a crankshaft Z. The device is equipped with a control mechanism for the loading chamber c. using a photoelectric sensor. Briquettes are formed by pressing. The device provides -. J ---,,. . :. u. -. adjusting the supply of material, but in a relatively complicated way, in addition, the briquettes are also not oh, have sufficient strength. . The closest technical solution, selected as a prototype, is a device for the production of raft-peat blocks 4 .. The device consists of a welded bed with placement on it with a matrix channel with a stamp (punch), loading hopper, hydraulic actuator, shutter, pressing chamber and an ejector of pneumatic driven peat blocks. The stamp / (punch) receives reciprocating motion from the hydraulic actuator via the rod. The matrix channel. Consists of a loading chamber and, to prevent it, the loading chamber in the upper part has a window for receiving peat mixtures from the hopper. This window is closed by rammers, which serve to seal the peat mixture and close the window of the loading chamber. The pressing chamber in the lower part has a window, which at the time of pressing is closed by a movable matrix, and then opens to unload the formed seedling block. In the upper part of the pressing chamber there is a pneumatic cutter for pushing out the peat block. Sequential operation of the movable matrix and pneumatic pusher is carried out by the pneumatic system control unit. There is a scraper knife on the pnevmotolkatel for trimming the separation of the peat block from the thrust plate. The device operates as follows - Torfos1 e, o from m; -., Conical hopper - accumulate AU under its own weight rolls into the loading chamber and fills it. During the initial movement of the stamp-punch, driven by the hydraulic cylinder, the pneumatic threshing flaps are closed, thereby cutting off a certain portion of the sprinkler mixture, sealing it in the loading chamber and simultaneously forming it. ;; ; .; . ; the upper surface of the matrix channel, a stamp-punch pushes a portion of the t-pho. the mixture into the pressing chamber to the thrust plate and the formation of peat, block. At the initial moment of withdrawal of the stamp-punch, control levers for air valves are activated, which consistently include pneumatic pushers for sliding the lower valve of the matrix and the upper pneumatic pusher to push the formed peat block .; ; .-., The thickness of the peat blocks depends on the pressing pressure and the volume of the loading chamber. The disadvantages of this device are: the low strength of peat blocks of low specific pressure during their formation, their uneven size due to inaccurate dosing of portions of peat, the destruction of peat blocks when ejected due to their adhesion to the rear fixed wall of the matrix channel. . The increase in the strength of the bulk J50kof, the uniformity of their volumetric mass and the reduction of fracture. When ejected, is ensured by .., I, .., WHAT In the installation, which contains, a loading hopper, a metering device ST505 matrix pressing chamber with a punch and shutter, hydro., - h the drive with the control unit, the dosing device is equipped with a slider with a volume-adjustable chamber, the slider is connected by a thrust and a cam follower with the piston rod of the hydraulic cylinder, and the shutter of the matrix chamber is made in the form of a wedge connected to the rod of the hydraulic cylinder ator, by means of a finger placed in the oval hole of the wedge, while in the middle part of the wedge a bore is made in which the spring is placed, and a hole in which the rod of the end sensor of the control unit is installed, the rod head being installed between the spring and the rod of the shutter cylinder. ., l / h,:, j; , -. ; ,,. ., -...:.
