AI Technical Summary

Technical Problem

The existing double-outlet straw feed picking and baling machine has problems with its baling device, such as poor strength and stability of the compression frame connecting plate, serious straw leakage, and easy damage to the square tube straw blocking structure.

Method used

By adopting a synchronous belt ring-shaped weed-blocking method, combined with guide wheels, support wheels, tensioning mechanisms and support pipes, the design of the compression frame is improved, increasing the stability of the synchronous belt and the weed-blocking effect. The working position of the pusher head is adjusted by the vertical compression cylinder to reduce pressure concentration.

Benefits of technology

It effectively solved the problems of grass leakage and damage to the grass-blocking structure, improved the stability of the compression frame and the grass-blocking effect of the synchronous belt, reduced uneven stress deformation of the compression frame, and improved the service life and efficiency of the device.

Abstract

This utility model relates to a baling device for a double-outlet straw feed picking and baling machine, including a frame, a double-piston rod compression hydraulic cylinder, a compression frame, and a timing belt. A double-piston rod compression hydraulic cylinder is installed on each of the front and rear sides of the frame. The double-piston rod compression hydraulic cylinders are located outside the baling chamber and extend laterally. The compression frame is installed inside the baling chamber, and its front and rear ends are connected to the drive ends of the two double-piston rod compression hydraulic cylinders via connecting plates. The compression frame can slide left and right under the drive of the two double-piston rod compression hydraulic cylinders to bale the straw. Sliding holes are respectively opened on the front and rear side walls of the frame, extending laterally. The connecting plates at the front and rear ends of the compression frame slide through the corresponding sliding holes. A timing belt and pulley system are installed on both the front and rear sides of the frame. The middle of the timing belt is wound around the corresponding pulley system, and the portions of the timing belt near its ends are respectively attached to the sliding holes on the left and right sides of the drive ends of the double-piston rod compression hydraulic cylinders.
