Wrapping device

Abstract

The invention relates to a wrapping device. The wrapping device comprises a main frame provided with a wrapping arm and connected with an agricultural machine, a wrapping framework arranged on the top of the main frame and inclined by an inclined cylinder, a rotary table rotatably mounted on a rear side of the wrapping framework and provided with a pair rollers used for rolling piles, and a loading arm mounted on a front upper side of the wrapping framework and operated by a loading cylinder to pull to-be-wrapped piles on the rotary table. A central combiner is mounted on a central position between the wrapping framework and a rotary table framework and can supply hydraulic pressure to a hydraulic motor of driving rollers and a cutting cylinder for cutting wrapping objects on outer peripheries of the piles independently from rotation of the rotary table. The central combiner comprises an outer combiner fixed on the center of the rotary table and rotating with the rotary table, and an inner combiner. Upper and lower bearings in inner combiner holes are connected to the main frame through the inner combiner formed in the axial direction of the outer combiner, and the inner combiner is free of influences of rotation of the outer combiner.

Description

technical field [0001] The present invention relates to wrapping devices, and more particularly to wrapping devices in which the central coupling mounted in the turntable of the wrapping device is improved such that the turntable and the rollers mounted on the turntable can be parallelized by hydraulic pressure Ground drive in order to ensure smooth operation and at the same time simplify the related construction. Background technique [0002] As is generally known in the art, ranchers stock animal feed crops, such as rice straw or grass, in order to use these forage crops as feed. If the forage crops are harvested and stored in warehouses only by piling up such forage crops dried on bare ground such as rice straw or pasture, the freshness of the forage crops is lost with the lapse of time. Furthermore, if the forage crop is completely dried out, the forage crop may be uncomfortable for livestock to eat, and even if the livestock eat the forage crop, the forage crop may bec...

AI Technical Summary

Problems solved by technology

Worse, due to damage or loss of small elements among those used to drive the turntable and rollers, it may be necessary to replace the entire turntable and rollers with new ones, and this troublesome failure frequently occurs in practice. Happening

[0011] In addition, although the turntable and the rollers mounted on the turntable should rotate at a set speed in a balanced state, the speeds of the turntable and the rollers may differ greatly from each other because drive transmission is performed individually

In this case, normal wrapping can become difficult, making it difficult to perform wrapping operations efficiently and continuously
