Изобретение относитс к оборудованию дл раскр жевки хлыстов и может быть использовано в лесной промышленности.The invention relates to equipment for digging logs and can be used in the forest industry.

Известно устройство дл безопилочного резани древесины, включающее основание, направл ющие с подвижно установленной на них державкой, снабженной ножом силового резани , привод перемещени державки , рамку, св занную с державкой ножа и дугообразный ограничитель с щелью 1.A device for sawing wood without cutting includes a base, guides with a holder mounted movably on them, provided with a power cutting knife, a drive for moving the holder, a frame associated with the knife holder and an arcuate stopper with a slit 1.

Известно также устройство дл безопилочного резани древесины, включающее основание, направл ющие с подвижно установленной на них державкой, снабженной ножом силового резани , привод перемещени державки, дугообразный упор, щарнирно св занный одни.м концом с основанием и запорный механизм 2.A device for sawing wood without cutting is also known, which includes a base, guides with a tool holder movably mounted on them, equipped with a power cutting knife, a drive for moving the holder, an arc-shaped stop, hingedly connected with one end to the base and a locking mechanism 2.

Но известные устройства дл безопилочного резани древесины отличаютс низкой производительностью.But the known sawing wood cutting devices have a low productivity.

Цель изобретени - повышение производительности устройства - достигаетс тем, что устройство снабжено центрирующими пластинами, одни концы которых щарнирно закреплены на обоих концах дугообразного ограничител и дугообразного упора, а другие подпружинены и размещены соответственно по середине дуги ограничител и упора.The purpose of the invention is to improve the performance of the device — it is achieved in that the device is provided with centering plates, one ends of which are hinged at both ends of the arcuate limiter and the arcuate stop, while others are spring-loaded and positioned respectively in the middle of the arc of the limiter and the stop.

На фиг. 1 изображено предлагаемое устройство , вид спереди; на фиг. 2 - то же, вид сбоку.FIG. 1 shows the proposed device, front view; in fig. 2 - the same, side view.

Устройство дл безопилочного резани древесины включает основание 1, направл ющие 2 с подвижно установленной на них державкой 3, снабженной ножом 4 силового резани , привод 5 перемещени державки с ножом, рамку 6, св занную с державкой ножа, дугообразный ограничитель 7 с щелью 8, дугообразный упор 9, щарнирно св занный одним концом с дугообразным ограничителем 7, привод 10 дл поворота дугообразного упора и запорный механизм 11.The device for sawing wood without sawing includes a base 1, guides 2 with a holder 3 movably mounted on them, equipped with a power cutting knife 4, a drive 5 for moving the holder with a knife, a frame 6 connected to the knife holder, an arcuate stopper 7 with a slit 8, arcuate an anvil 9, which is hinged at one end with an arcuate stopper 7, a drive 10 for rotating the arcuate anvil and a locking mechanism 11.

Claims

The arcuate stopper 7 and the arcuate stop 9 are provided with centering plates 12, one ends of which are hinged at both ends of the arcuate stopper and the arcuate stop. The other ends of the plates 12 are placed respectively in the middle of the arc of the restrictor and the stop and loaded with springs 13. The shutter 14 with the drive 15 serves to feed the timber (logs) into the cutting zone. The hydraulic cylinder 16 is designed to move the device along the timber. The device operates as follows: the cutting material is fed through the shutter 14 to the arcuate stopper 7, and the actuator 10 rotates the arcuate stop 9, which presses the wood to the stopper. Plates 12 automatically center the timber. At the same time, the mechanism 11 locks the arcuate stop 9. The actuator 5 moves the holder 3 with the knife 4 along the slit 8 until the timber is completely cut. After the knife has returned to its original position, the locking mechanism is activated, and the actuator 10 rotates the arcuate abutment to the initial position. The actuator 15 rotates the shutter 14 and the log is removed from the device. The device is moved by a hydraulic cylinder 16 for installation at a predetermined position according to the program for cutting timber. The device allows to reduce the duty cycle and increase productivity when cutting forest material by 10-15%. The invention of the device for sawing wood without sawing, comprising a base, guiding with a tool holder movably mounted on them, provided with a power cutting knife, a drive for moving the holder, a frame connected with a knife holder, an arcuate stopper with a slit, an arcuate stop, pivotally connected at one end With an arcuate stopper, a drive for turning the arcuate abutment and a locking mechanism, characterized in that, in order to increase productivity, the device is provided with centering plates, one ends which are hinged at both ends of the arcuate limiter and arcuate stop, and the others are spring-loaded and placed respectively in the middle of the arc of the limiter and the stop.
