Description

Adjustable anti-dragging pile-up compacting machine for straw returning machine Technical Field The invention belongs to the technical field of agricultural machinery, and particularly relates to an adjustable anti-dragging pile-up compacting machine for a straw returning machine. Background With the rapid development of agricultural automation, agricultural machinery equipment is continuously abundant. In the tillage operation, the compactor bears important functions of crushing soil, compacting, preserving soil moisture, promoting seedling, improving drought resistance and cold resistance of soil and the like. In actual operation, proper compacting force is selected according to soil texture and soil moisture content, and is generally classified into three grades of light, moderate and heavy. However, traditional roller structural style is single, and the ballast force is adjusted and is generally relied on the increase and decrease balancing weight, and inefficiency and inconvenient are adjusted, and when the uneven or topography fluctuation of straw distributes greatly, the unstable ballast force easily forms the straw in the front of the roller and drags the heap and cause stall scheduling problem, influences operation quality and operating efficiency. In addition, the traditional roller shaft is rigidly connected with the machine, a damping device is lacked, impact load is large during operation, and information feedback is lacked, so that a driver cannot know the state of the roller shaft and the pressure of the roller in real time.
