A bundling device for a small rice harvester

Abstract

A small rice binder bundling device comprises a box, a transmission device, a knotting device, a rope compressing and shearing component and a rope collecting part, wherein the transmission device, the knotting device, the rope compressing and shearing component and the rope collecting part are mounted on the box. A rope compressing and shearing cam is fixedly mounted on a power shaft of the transmission device and connected with the rope compressing and shearing component in a matched manner to drive a rope compressing and shearing block to compress downwards, so that a rope is compressed and sheared. A knotting bevel gear is connected with a knotting bevel matching gear of the knotting device to drive the beak-shaped knotting device to rotate, open and close, so that knotting is achieved. A rope fastening bevel gear drives a crank connecting rod mechanism of the rope collecting part to drive a hook of the rope collecting part to send a bundling rope to the rear end of a second rope compression block from the front end of a first rope compression block along a track plate, and the knotting device is matched with the rope compressing and shearing component to finish actions of rope compressing, knotting, rope shearing and rice bundle laying. Compared with an existing rice binder bundling device, the small rice binder bundling device is simple in structure, compact and practical, the bundling device is mounted on a rice binder, rice straws can be rapidly bundled and neatly laid, labor intensity is greatly relieved, production efficiency is improved, and the bundling device has high practical values.

Description

technical field [0001] The invention relates to the field of rice harvesting and bundling mechanized harvesting, in particular to a bundling device for a small rice harvester. Background technique [0002] At present, in the field of domestic rice harvesting and bundling mechanized harvesting, rice cutting and bundling harvesting machines mainly use D-shaped knotters imported from Germany, Japan and other countries to cooperate with bundling machines; The knotter uses two tying ropes to be rotated by two knotter hook shafts to make two knots; the spare part for knotting with the hook part in the middle of the two knotter hook shafts is used to pull the rope back over the knife with a spring, When the rope catching parts on both sides press down the rope, the rope segment between the knots is broken, so that each rice bundle has two knots to make the rope tightly tied; it has a certain ability to knot the rope, but it uses two The knotting of a knotting hook shaft makes the ...

[0002] At present, in the field of domestic rice harvesting and bundling mechanized harvesting, rice cutting and bundling harvesting machines mainly use D-shaped knotters imported from Germany, Japan and other countries to cooperate with bundling machines; The knotter uses two tying ropes to be rotated by two knotter hook shafts to make two knots; the spare part for knotting with the hook part in the middle of the two knotter hook shafts is used to pull the rope back over the knife with a spring, When the rope catching parts on both sides press down the rope, the rope segment between the knots is broken, so that each rice bundle has two knots to make the rope tightly tied; it has a certain ability to knot the rope, but it uses two The knotting of a knotting hook shaft makes the structure of the whole rope knotter complex, difficult to process, and high in cost, which is not conducive to the supporting use of small and micro rice cutting and bundling machines.
