Net winding device and method of circular bundling machine

Abstract

The invention belongs to the technical field of agricultural machinery and equipment, in particular to a net winding device of a circular bundling machine. The device comprises a machine frame, a silknet hanging rod 1, a stepping motor I 3, a stepping motor II 8, a PLC control system 12, a net guiding mechanism, a wind power net feeding mechanism and a net cutting mechanism. According to the device, the PLC control system controls three operation processes of net guiding, net feeding and net cutting, the net guiding mechanism adopts a double-direction thread net guiding roller and a rubber smooth roller to form a pair of rollers, and extends the silk net to two sides while guiding the net; the wind power net feeding mechanism rectifies the wind blown by a fan through a blowing head, stably blows out the wind flow scattered along the horizontal direction, and cleanly blows the silk net guided by the net guiding mechanism to a feed inlet of a bundling chamber of the circular bundling machine; and the net cutting mechanism adopts the form of a crank connecting rod driving a sliding knife, and the displacement curve of the sliding knife is limited to two sections of'straight line+curve'through slideways. The invention further relates to a net winding method of the circular bundling machine. The device and the method have high reliability, the round straw bundles are evenly wound on the net, and the net cutting is complete, so that the success rate of net cutting and the uniformity of net breaking can be improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and equipment, and in particular relates to a net winding device and method for a round baler. Background technique [0002] my country is rich in straw resources, and using a round baler to pack straw into round bales is one of the commonly used straw harvesting methods, which can be more convenient for transportation and storage. The round baler uses a number of steel rollers arranged around the circumference to form a bale chamber. The straw is rolled into a round bale through the rotation of the steel roller, and then several layers of wire mesh are wrapped on the cylindrical surface of the round bale to increase the density of the bale and keep the round bale. The bales will not loosen during transport. Therefore, the winding device is one of the core components of the round baler, and it needs to be able to smoothly introduce the wire mesh into the baling room, and cut the wi...
