An automatic netting device for a baler

Abstract

The present invention discloses an automatic net winding device for a bundling machine, belongs to the technical field of agricultural machinery, and aims to solve the problem that an existing straw bundling machine is relatively low in automation level due to manual bagging in packaging. The double-cantilever type automatic net winding device is designed; a net rope is fixed by cantilevers; the cantilevers are fixed to a large tooth disc; one end of the net rope is fixed to a net breaking mechanism; the net rope is driven to be wound on the outer side of a square straw bundle by rotation of the large tooth disc; and the firmness of a square straw bundle bag is ensured by mutually overlying two sides together in an opposite winding manner. The net breaking mechanism comprises parts such asa net pulling plate, a knife rest and a net breaking blade; the net pulling plate is driven by a hydraulic cylinder with double strokes to realize automatic clamping and release of the net rope; after the net pulling plate pulls the net rope tightly, the net breaking blade extends out for cutting off the net rope; and the mechanism can enable the net rope to be pulled tightly in net breaking, sothat the net breaking blade is ensured to cut off the net rope easily and the success rate of net breaking is ensured.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery. Background technique [0002] The straw baler is a kind of machine used for straw recycling. After the straw is picked up from the ground, after crushing, kneading, soil removal and other processes, it is transported to the collection bin by the fan, and then falls into the collection bin from the collection bin. Into the compression bin, the straw is baled into bundles through a hydraulic device. The bundled straw needs to be covered with a layer of packaging bags during the transportation process. The existing straw balers are all manually operated. An operation room is specially set up at the outlet of the straw baler, and the workers stand in the operation. Manual bagging in the room completes the packing process. Due to the low degree of automation and high work intensity, this method is not suitable for continuous work for a long time, so the efficiency is low. Moreover, t...

Problems solved by technology

Due to the low degree of automation and high work intensity, this method is not suitable for long-term continuous work, so the efficiency is low

Moreover, the straw baler will raise a large amount of dust into the operating room during the working process, and the working environment is poor. Therefore, the realization of automatic packaging is a problem that needs to be solved urgently for the straw baler.
