Description

Technical Field

[0001] The utility model relates to the technical field of traction steering transmission, in particular to a traction steering transmission device for a straw crushing and baling machine. Background Art

[0002] The existing crushing and baling machine for processing field straw into feed includes a straw picker, a pusher connected to the picker to move the straw to one side of the baler, a straw conveying fan connected to the pusher, a straw crusher, a straw conveying fan after crushing, an upward channel for wind-transported straw debris, a briquetting and baling device for straw debris, a hydraulic system, a traction and power input system, wherein the traction and power input system is used for steering and transmitting the power of the traction vehicle to the baler. Although the aforementioned baler can crush, briquette and pack the straw on the spot in the field more efficiently. However, it is found that there are still shortcomings that need to be improved during use. The more prominent common problem noticed by the applicant is that the traction and power input system cannot realize the steering of the baler during the power output process.

Each time the baler changes ridges and turns, it needs to frequently open and close the power source, which greatly shortens the service life of the clutch. Utility Model Content
