Abstract

The invention relates to the grinding of various materials, in particular, the grinding of branches in the forest industry, sugarcane in the food industry and reeds in the pulp and paper industry. The purpose of the invention is to simplify the design, reduce material and energy intensity. In the branch chipper, the cutting elements are made in the form of saws 2. A two-maxillary grip is used to form a bunch of branches and to fix them. The jaw 4 is held by a spring 6 and an abutment. The jaw 5 is driven by the power drive 7. The jaws 4 and 5 are provided with slots 8. After the lobes of the maxillary grip are loaded, the jaw 5 slides over the jaw 4, which until a certain time is held by the spring 6 and ensures the formation and fixation of the bunch of limbs. The double-jaw grip advances on the circular saws 2, which, through the slits 8, divide the bunch of branches into separate segments. 1 il.

The invention relates to the grinding of various materials, in particular to the grinding of branches in the forest industry, sugarcane in pis, Eva, and reeds in the pulp and paper industry.

The purpose of the invention is to simplify the design, reduce material and energy intensity.

The drawing shows a chopper, osh.i view.

The bite shredder contains a base AND cutting elements in the form of disk elbows 2 assembled on shaft 3, a double-jaw gripper with jaws 4 and 5 mounted by the throat upwards. The jaw 4 is held by a spring 6 and an abutment (not shown), a person | Ghost 5 is set in motion by means of a power drive 7. Jaws 4 and 5 are provided with slots 8.

I The shredder works as follows.

Before loading, the jaw 5 of the gripper is retracted to the {local position) by means of the actuator 7. The jaw 4 with the help of the core 6 is led out of the zone of action of the disjug saw 2 and, having met the stop, is fixed to this position. The jaw grip is ready to load the boughs. After loading, the jaw of the hjoro is gripped by the boughs by the action of the force g (drive 7, the jaw 5 is pulled over the jaw 4, which is held for a certain time by the spring 6 and provides for shaping (bunching and fixation of the bunch of branches).

five

the resistance of the spring 6 is overcome and the double-jaw grip begins to slide on the saw blades 2 of the cutting member, which, entering the slot 8 of the jaws 4 and 5, divide the branching branch into separate segments. By the return stroke of the actuator 7, the jaw 5 moves to the extreme position, and the jaw 4 by the spring 6 is withdrawn from the zone of action of the cutting bodies and, until it stops, is fixed. The jaw 5, retracted to the extreme position, allows the ground mass to be unloaded (under the force of gravity).

The proposed shredder is reliable in operation and economical, which makes it possible to use it in a mobile version on TT-4 type skidders.
