Combined processing machine for returning straw to field and crushing root stubble

Abstract

A combined agricultural machine driven by the power output shaft of tractor for breaking the straw or stalk and the stubble and returning the broken straw or stalk back to field is composed of the straw (or stalk) cutting roller arranged on its frame and driven by the left output shaft of speed variator, the stubble cutting roller arranged on its frame and driven by the right output shaft of speed variator, the speed variator with input shaft linked to the power output shaft of tractor via universal joint, and ground wheels.

AI Technical Summary

Problems solved by technology

[0002] Due to the vast land area of ​​our country, different regions have different requirements for agronomy. Therefore, the treatment methods for the remaining straw and root stubble after harvesting high-stalk crops such as corn and sorghum are also different. The original machines can only return the straw separately Field or stubble crushing operations, in areas where straw returning and stubble crushing operations are required, only two types of machines can be used to work on the ground separately, resulting in secondary rolling of the cultivated land and affecting the ventilation and water permeability of the soil

However, the combined operation machine for field returning and stubble crushing that has just appeared cannot perform straw returning or stubble crushing operations alone. When using this machine to work in areas where only straw returning to the field or stubble crushing operations are required, the operation will be greatly increased. cost

Due to the above reasons, these three types of machines are not suitable for large-scale promotion and use, especially for cross-regional operations.

[0003] In addition, only hammer claws or L-shaped throwing knives are installed on the returning knife roller of the original straw returning machine

When only the L-shaped flailing knife is installed, because the knife itself is light in weight and the moment of inertia is small, it needs a large kinetic energy when crushing the straw, which increases the power consumption of the tractor and affects the working speed of the implement. highly fragile

When only the hammer claws are installed on the cutter roller, although the moment of inertia of the cutter is increased and the damage of the cutter is reduced, due to the limitation of the arrangement of the hammer claws, many long broken straws overflow from both sides of the cutter roller and the machine tool. , and the ability of the hammer claw to pick up the lodging straw is poor, so it seriously affects the crushing quality of the straw by the machine tool
