Same-tooth-direction double-toothed-disc driven knotter and bundling machine provided with same

Abstract

The invention provides a same-tooth-direction double-toothed-disc driven knotter and a bundling machine provided with the same. The same-tooth-direction double-toothed-disc driven knotter comprises a large toothed disc, a small toothed disc, a knotter main support, a cutter arm II, a winding, buckling, clamping and biting mechanism III, a rope clamping device IV and a rope clamping device driving mechanism V; the large toothed disc is provided with at least one large toothed disc gear section along the circumference; the small toothed disc is provided with at least one small tooted disc gear section along the circumference; and the tooth punching direction of the large tooted disc gear section is the same as that of the small toothed disc gear section. According to the same-tooth-direction double-toothed-disc driven knotter, left-hand worm transmission of the driving rope clamping device is improved into right-hand worm transmission, the helical angle of an involute helical gear for space 72-degree staggered shaft worm transmission is reduced, radial force borne by a worm is greatly reduced, and transmission efficiency is improved, so that abrasion of a worm pair is reduced, the bending strength requirement of a worm shaft is lowered, and the reliability of the knotter is improved.

Description

technical field [0001] The invention relates to the technical field of grain harvesting and bundling, in particular to a knotter driven by double toothed discs in the same tooth direction and a bundling machine equipped with the knotter. Background technique [0002] The square bale baler is an important equipment for straw processing after crop harvesting. The knotter is the core component of the square bale baler. It is an integrated automatic device that uses ropes to tie knots and has a complex spatial structure. , has the characteristics of high manufacturing difficulty, high assembly precision and reliability requirements, and has been widely used on square balers around the world. Chinese invention patent 201510161254.6 has invented a double tooth disc driven knotter, which has the characteristics of reasonable structure, easy processing and assembly, and low manufacturing cost. However, after these knotters have been used for a certain period of time, because the wo...

AI Technical Summary

Problems solved by technology

However, after these knotters have been used for a certain period of time, because the worm is affected by the large radial force of left-hand rotation, it is easy to bend and deform, and the change begins to cause failures such as hooks and pliers biting single-strand ropes.

If the knotting operation is continued, the knotter will frequently fail to trip and needs to be shut down, and manual removal is time-consuming and laborious

Therefore, it is necessary to design the knotter system while maintaining the advantages of easy processing and assembly to solve the problem of easy deformation of the worm
