Rape stalk bundling device

Abstract

The invention provides a bundling device for rape straw. The device comprises a machine frame, a collecting mechanism, a rope sending mechanism, a knotting mechanism and a pushing mechanism; the collecting mechanism comprises a straw collecting shaft having arc-shaped harrow teeth and a first crank rocker assembly, the rope sending mechanism comprises a rope sending shaft having a rope sending needle and a second crank rocker assembly, the pushing mechanism comprises a pushing shaft having arc-shaped blocking teeth, and the knotting mechanism comprises a knotting shaft, a knotter and a knot bundling clutch mechanism; a bundling chamber used for bundling the rape straw is formed among the machine frame, the arc-shaped harrow teeth and the blocking teeth, and the other end of the second crank rocker assembly is connected to the knotting shaft; and the device further comprises a measuring mechanism used for metering a quantity of the rape straw entering the bundling chamber, the meteringmechanism is connected with the second crank rocker mechanism and allows the knot bundling clutch mechanism to push the second crank rocker assembly to move to make the rope sending shaft and the knotting shaft linked to complete knot bundling action when the rape straw in the bundling chamber reaches a designed quantity. The device provided by the invention has the advantages of having a compactand simple structure and good bundling quality, and being capable of precisely controlling a bundling quantity.

Description

technical field [0001] The invention relates to the technical field of rapeseed segmental harvesting machinery, in particular to a rapeseed stalk bundling device. Background technique [0002] Due to differences in varieties, regions, and planting systems, combined harvesting and segmental harvesting of rapeseed will coexist for a long period of time at present and in the future. Segmented harvesting means that the rapeseed at the ripening stage is cut down manually or with a windrower, and then spread on the stubble to dry, and the post-ripening is threshed manually or with a picking thresher. Southern paddy fields are vigorously promoting the three-cropping system of rice, rice and oil, that is, two crops of rice and one crop of winter rape. In order to vacate the land in advance and facilitate the subsequent planting of early rice, it is necessary to cut and bundle the rapeseed at the ripening stage with a baler, and transfer the bundled rapeseed to the drying field in t...

AI Technical Summary

Problems solved by technology

The cutting and binding machine can complete the mechanized bundling of rape at the ripening stage, but because the size of each bundle of rape is different, the degree of tightness of the bundling is also different, the cutting and bundling machine cannot measure the number of rape stalks entering the bundling room, and cannot guarantee bundling The size of each bundle of rapeseed is as consistent as possible, and the size of the bundle of rapeseed cannot be adjusted
