Anti-winding shaft and fastening device for cutting disk of cutting machine

Abstract

The invention discloses an anti-winding shaft and fastening device for a cutting disk of a cutting machine. The anti-winding shaft and fastening device comprises a sawing disk (1), an inertia disk (2), a connecting bolt (3), a base (4), a base bearing (5), sawing teeth (10), a rotating shaft (11), a positioning upper gland (12), a positioning lower gland (13), a locking nut (18), a rotating shaft end screw (19), a positioning upper gland inner hole (20), a positioning upper gland hexangular hole (21) and a positioning upper gland inner ring (22). The anti-winding shaft and fastening device is characterized in that a moving blade (6) and a moving shank (7) are fixed to the rotating shaft (11) through moving cutter fastening bolts (9); the moving blade (8) is fixedly welded to the base (4); a gap (23) is formed in the positioning upper gland inner hole (20); a gap is also formed in a positioning lower gland inner hole; a fastening presser inner tongue (16) on a fastening presser (14) extends into the gaps (23) in the positioning upper gland inner hole and the positioning lower gland inner hole; and a fastening presser outer locking sheet (15) on the fastening presser (14) is bent to press the locking nut (19).

Description

technical field [0001] The patent of the present invention relates to an anti-winding shaft and a fastening device, in particular to an anti-winding shaft and a fastening device for a cutting disc of a cutting machine. Background technique [0002] As we all know, harvesting of rice and wheat requires harvesting machinery. In the management of mulberry gardens, several pruning and cutting of mulberry trees are carried out every year, including grafting and improvement of mulberry trees, summer cutting, winter pruning and cutting of mulberry cultivation. , so that the mulberry leaves grow better in the coming year, cutting machinery is needed. [0003] Cutting machinery is mainly manual shears, and electric branch shears and pneumatic shears have also been introduced in recent years. Manual cutting is very laborious, and the cutting speed is very slow; commercially available electric branch shears are powered by storage batteries, and the power is limited. The power of the c...

AI Technical Summary

Problems solved by technology

Manual cutting is very laborious, and the cutting speed is very slow; commercially available electric branch shears are powered by storage batteries, and the power is limited. The power of the cutting motor is low, and it is easy to cut small branches. Shorter, the cost price is higher;

[0004] Most of the harvesting machines sold on the market now use disc-toothed saw-type blades, and the connecting drive shaft of the blades is often wound on the rotating shaft of the cutting disc by weeds and uncut branch bast, which not only increases the The frictional resistance between the cutter head and the load-bearing fixed seat will consume part of the kinetic energy, and if it is too entangled, if it is not removed, the saw head will not be able to rotate and cannot work; Do not loosen the saw disc compression screw, which will cause the cutter disc to be thrown out and cause serious injury to the human body; removing the entanglement will also take time and delay work

[0005] Cutting the branches with cutting power will increase the resistance several times. When cutting thick branches, the cutter head will be stuck on the branches or the saw head will decelerate and rotate, which will also cause the saw head to loosen the compression nut, and the cutter head will be thrown off. cause serious bodily injury
