Knotting mechanism based on bionic principle

Abstract

The invention relates to a knotting mechanism based on a bionic principle which is mainly composed of a fixed frame, a knotting fixed frame, a winding device, a knotting device, a knotting driving device, a winding driving device and a power transmitting device. The winding device and the knotting device are arranged in parallel to guarantee power transmitting stability, and the winding device and the knotting device cooperate with a rope feeding mechanism to improve the knotting success rate. The power transmitting device is provided with a multi-channel power transmitting mechanism. By means of transmission between a bevel gear disk and a bevel gear, transmission between the bevel gear and a straight gear, transmission between a rack and a winder and transmission between the straight gear and a knotting finger straight bear, intermittent and synchronous transmission of multi-channel power can be achieved. A knotting tongue and a knotting finger of the knotting device are in hinge connection, a knotting pressing plate can control the opening and closing size of the knotting finger and the knotting tongue, and then knotting and tripping operation of binding ropes are achieved. The knotting machine based on the bionic principle achieve straw compressing and baling operation, the straw baling and knotting efficiency is greatly improved, and the agricultural labor cost is reduced.

Description

technical field [0001] The invention relates to the field of agricultural machinery and equipment, in particular to a knotting mechanism based on the bionic principle. Background technique [0002] my country is a large agricultural country, and there are many kinds of stalk crops such as rice, millet, and sorghum, which are widely distributed and have large yields. In many rural areas of our country, crop straw is the main source of fuel for rural life and roughage for livestock. When recycling straw, most farmers use traditional manual bundling, which is labor-intensive and inefficient, and there are wires in the existing baler. It is difficult to accurately transmit the surrounding straw to the knotting mechanism, it is difficult to control the timing of knotting in space, the tightness of the knotted rope is low, the unevenness of the weight bundles leads to difficulty in pushing, and the inconsistent cooperation of multiple components, etc., cannot satisfy farmers and e...

In many rural areas of our country, crop straw is the main source of fuel for rural life and roughage for livestock. When recycling straw, most farmers use traditional manual bundling, which is labor-intensive and inefficient, and there are wires in the existing baler. It is difficult to accurately transmit the surrounding straw to the knotting mechanism, it is difficult to control the timing of knotting in space, the tightness of the knotted rope is low, the unevenness of the weight bundles leads to difficulty in pushing, and the inconsistent cooperation of multiple components, etc., cannot satisfy farmers and enterprises. Demand for Straw Bundling Equipment

[0003] Chinese Patent No. CN200910248496 discloses a bundling device for a baler, in which the bevel gear of the rope gripper and the bevel gear of the knotting mouth mesh with each other, and the rope gripper and the knotting mouth are not arranged in parallel, resulting in rope gripping and knotting operations The timing is difficult to control, and the knotting efficiency is not high

Furthermore, the knotting power mechanism of the bundling device adopts an unwinding arm mechanism, and the bevel gear ring of the unwinding arm mechanism is fixed on the lower part of the transmission shaft, and the knotting and pressing rope mechanism is driven by the transmission shaft to operate, that is, the bevel gear gear and the bevel gear ring of a single structure are adopted. The transmission mode of the transmission shaft is difficult to accurately control and transmit the knotting driving force, and cannot meet the requirements of the existing agricultural field for fast and efficient bundling and knotting
