AI Technical Summary

Technical Problem

Failure to remove the straw stubble from the previous crop in time after sowing will be detrimental to the root development of newly sowed crops and will easily induce pests and diseases, resulting in reduced yields.

Method used

A cultivating cutting machine for crop planting is designed, including a cutting mechanism and a soil cultivation roller. The cutting mechanism is composed of a cutting roller, a staggered cutting claw and a stop rod. The cutting claw has a "piece"-shaped cutting knife, which can effectively cut off straw stubble, and grab and cut through vertical slices to avoid hoeing into the ground too deep.

Benefits of technology

The cutting machine can effectively cut off straw stubble, promote crop root development, avoid the occurrence of pests and diseases, and keep the soil level through the design of soil cultivation rollers to reduce the impact of debris.

Abstract

The utility model provides an intertillage stubble cutting machine for crop planting, which comprises a machine frame, the machine frame comprises a left side plate and a right side plate, a top cover is arranged between the left side plate and the right side plate, and two ends of the top cover are respectively and fixedly connected with the left side plate and the right side plate. A stubble cutting mechanism is arranged on the front side of the lower portion between the left side plate and the right side plate, a hilling roller is arranged on the rear side of the stubble cutting mechanism, a blocking rod is arranged above the hilling roller, the stubble cutting mechanism comprises a stubble cutting roller, the two ends of the stubble cutting roller are connected with the left side plate and the right side plate through bearings respectively, and a plurality of stubble cutting claws are distributed on the stubble cutting roller in a staggered mode. The stubble cutting claw cuts off straw stubbles, follow-up growth of crops is facilitated, the stubbles can be removed, and the situation that newly-sown crops are damaged due to the fact that the stubble cutting claw is hoed into the ground too deep can be avoided due to the design of the stubble cutting claw.
