Description

(54) QUICK RING HEAD

The invention relates to machines and mechanisms for pruning and can be used in the forest industry.

The working body of the delimbing ma-III is known. The power cutting tools include several symmetric pairs of V-shaped power knives mounted on brackets with the possibility of individually pushing them onto the treated timber.

This arrangement of knives, although it increases the reliability of copying and, consequently, improves the quality of processing, but this causes a complication of the design, an increase in metal consumption, as well as energy intensity due to the presence of a large number of power cylinders for pulling the knives.

The knothead is known for thrusting, including the base, which is hinged on it with the help of rotary drive levers. Arc-shaped lateral and upper and power cutting cans, 1 kinematically connected between SOs;

The disadvantages of this design are: poor quality of processing of timber, since the copying of the trunk shape is not efficient enough, the complexity of construction, low reliability due to the significant number of hinges.

The purpose of the invention is to improve the quality of pruning by improving the trunk shape of the treated timber.

The goal is achieved by the fact that such a knotted head is screwed with elastic elements and additional levers with red-linear knives of power cutting, which are mounted on the shafts, and the elastic elements are located between the main and dolol.n. power levers and, moreover, the power cutting knives have different Curvature.

The drawing shows a general view of the delimbing head.

The knotted bore head consists of a base /, on which the shaft 2 is mounted with the supports 2 and 3 and the shaft 7 is mounted on the supports 5 and b. The shafts 4 ai 7 are equipped with cross-sleeves 8 and 9, the ends of which are interconnected by hydraulic cylinder 10. In the front part of the delimbing head, on the shafts 4 and 7, the main pivot levers L and 12 are rigidly fixed with hinged curvilinear knives /, 3 and 14. The levers // and 12 with the knives 13 and 14 form the first main along c. The second one, which is located consistently along with, is crooked.

Claims (2)

Form m oud invented and I 1. A delimbing head, comprising a 15 base, in the supports of which pivot levers with curved power cutting knives and a lever rotation drive are installed on the shafts, characterized in that, in order to improve the quality of cutting the knots by improving the shape of the trunk of the timber being processed, it is equipped with elastic elements and additional levers with curved power cutting knives mounted on shafts, and elastic elements are located between the main and additional levers. 2. The delimbing head according to claim 1, characterized in that the blades of the power 30 knowledge have a different curvature.
