Double-fluted disc driving knotter

Abstract

The invention discloses a double-fluted disc driving knotter and relates to the technical field of straws or pasture harvesting bundling. The double-fluted disc driving knotter comprises a small fluted disc, a knotter rack, a large fluted disc, a cutter arm assembled on the knotter rack, a reeling buckling pincer engaging mechanism (R) and a rope clamping device driving mechanism (Q), wherein a composite fluted disc of the double-fluted disc driving knotter is divided into the small fluted disc and the large fluted disc; the small fluted disc and the large fluted disc are coaxially fixed on two ends of a main shaft hole of the knotter, so the knotter main shaft can be stressed in a balanced way and work stability of the knotter can be improved; three rope clamping notches are formed on the rope clamping disc, so the length of a rope cutting sheet slip-cutting a bundling rope can be prolonged and rope cutting action of the knotter is reliable; and a cutter arm roller rolls along a spatial profile curved surface and has a linear contact with the spatial profile curved surface of the surface of a cam, so bearing capacity can be enlarged and wear can be reduced. The double-fluted disc driving knotter is rationally structured and characterized by easy processing and assembling, low manufacturing cost and reliable knotting.

Description

technical field [0001] The invention relates to the technical field of straw or pasture harvesting and bundling, in particular to a knotter driven by double toothed discs. Background technique [0002] The square bale baler is widely used in the collection and bundling of rice straw and dry green forage in rural areas and pastures. The knotter is the core component of the square bale baler, and its main function is to send the rope feeding mechanism to the The rope clamping is used to complete the actions required for bundling and knotting, such as wrapping the buckle, biting the rope, cutting the rope, and breaking the buckle to form a knot. Tie the two ends of the rope into a dead knot to prevent the compressed bale from loosening. The bundled and knotted bales have a high density, which is convenient for transportation and storage, and is very conducive to the utilization of biomass energy such as straw. [0003] At present, the most widely used type C and D knotters, fo...

AI Technical Summary

Problems solved by technology

[0007] The technical problem to be solved by the present invention is that the uneven force of the composite toothed plate leads to complex spatial structure of the knotter, which is difficult to manufacture and requires high assembly precision; when the rope feeding mechanism cuts the rope, the position of the rope head is close to the upper part of the blade, which is not conducive to cutting Rope head; Cylindrical cam wears a lot, which affects the service life of the knotter
