Description

Изобретение относитс к лесной прогфлиленности, в частности к оборудованию дл измельчени |цепы. . The invention relates to forest blight, in particular to equipment for shredding chains. .

Известна установка дл дробпенн пней, включанмца каркас, механизм подачи , режуций Механизм 1.Known installation for shot pellets stumps, including the frame, the feed mechanism, the cutting mechanism Mechanism 1.

Известна также рубильна мавина дл измельчени лесоматериалов на технологическую щепу, включающа корпус , загрузочное устройство, ротор в виде барабана, между которыми параллельно оси вращени ротора установи лены ножедержатели с дистанционн л и буртами 2.Also known is a chipping mavine for chopping timber for technological chips, including a housing, a loading device, a rotor in the form of a drum, between which are installed the knife holders with spacers and shoulders 2 parallel to the rotation axis of the rotor.

Недостатком известных машин вл етс сложность конструкции и плохие услови удалени щепы.A disadvantage of the prior art machines is the design complexity and poor chip removal conditions.

изобретени - упрощение кон струкции и улучшение условий удале-у НИИ щепы. the invention is the simplification of the design and improvement of the conditions of removal of the chip institute.

Достигаетс это тем, что барабан выполнен в виде смонтированных с за зором и скрепленных стержн ми колец, при этом в зазорах между кольцакш на двух смежных Ътержн х установлены блоки креплени ножей , ка цолй посухедуюЩий блок Креплени ножей имеет об-i сдай с предыдущим блоком креплени иожей креп щих стержень и расположен с противоположной стороны кольца.This is achieved by the fact that the drum is made in the form of rings mounted with a gap and fastened with rods; The brass rod is located on the opposite side of the ring.

На фиг.1 изображена предлагаема машина, поперечный разрез; на фиг.2 -; то же, продольный разрез; на фиг.З схема установки блоков креплени ножей; на фиг.4 - вид блоков креплени ножей; на фиг.5 - схема расположени при последовательном перемещении режущих кромок резца в зоне резани .Figure 1 shows the proposed machine, a cross-section; figure 2 -; the same longitudinal section; Fig. 3 is a diagram of the installation of knives attachment blocks; Fig. 4 is a view of the blocks of fastening knives; Fig. 5 is a layout diagram with sequential movement of the cutting edges of the cutter in the cutting zone.

Машина включает ножевой барабан 1, The machine includes a knife drum 1,

10 привод 2, передачу 3. Ножевой барабан 1 смонтирован на подшипниках в корпусе 4 с загрузочной шахтой 5 в верхней части корпуса 4, в нижней части корпуса 4 выполнено разгрузоч15 ное окно 6. Со стороны привода барабан 1 имеет торцовую стенку 7, выполненную в виде конической ступицы и закрепленную на валу 8.10 drive 2, transmission 3. Knife drum 1 is mounted on bearings in housing 4 with loading shaft 5 in the upper part of housing 4, in the lower part of housing 4 a relief window 6 is made. On the drive side, drum 1 has an end wall 7 made in the form of conical hub and mounted on the shaft 8.

Ножевой барабан 1 выполнен в ви20 де набора тонких стальных колец 9, скрепленных между собой с зазором через дистанционные втулки 10 стержи 1-«и 11. (Дистанционные втулки 10 имеют высоту, равную толщине блока The knife drum 1 is made in a type of thin steel rings 9, fastened together with a gap through spacers 10 rods 1- "and 11. (Distance bushes 10 have a height equal to the thickness of the block

25 креплени ножей.25 fastening knives.

Claims

In the gaps between the rings, there are staggered each on two rods 11 knives fixing blocks 12, each of which has a blade cutter 13. Recyclable timber 14 is placed in the loading shaft 5. The chipper machine works as follows. Turning on the drive 2 through the transfer 3, start-up of the drum 1 is carried out. The processed material 14 is fed to the cutter drum 1 via the loading shaft 5. The cutting cutters 13 are carried out. cutting timber. At the same time, the lamellar cutter 13, located in the middle of the knife drum 1, cuts trapezoidal chips, and subsequent plastic cutters 13 cut the chips into a parallelogram form. In this case, along the cylindrical surface of rotation of the platinum cutters 13, cutting is performed close to the fiber parallel, and along the conical surface of rotation of the end edges of the cutters 13, the fibers are transversely cut at an angle. Due to the symmetrical arrangement of the blade cutters 13 relative to the transverse axis of the blade drum 1, the axial displacement of the timber does not occur, the length of the fibers is maintained to a predetermined one. The resulting chips 15 are drained by centrifugal force through the gaps between the steel rings 9 to the process flow. The cycle is repeated. Claiming machine for chopping timber for process chips, including a housing, a loading device, a rotor in the form of a drum, between which parallel holders of the rotor are installed, there are distance holders with remote shoulders, in order to simplify the design and improve the conditions for removing chips the drum is made in the form of rings mounted with a gap and fastened with rods, while in the gaps between the rings on the two adjacent rods the knives j are installed each next b c has a common unit with predschuschim attachment crepe blades conductive rod and disposed on the opposite side of the ring.
