Machine for imbedding stubbles and plowing

Abstract

The invention provides a machine for imbedding stubbles and plowing which comprises a transmission system, a suspension arrangement, a soil fending and leveling arrangement, and an blade shaft assembly mainly consisting of a blade shaft, a stubble burying blade, a soil scrapping board and a blade chamber, wherein the stubble burying blade is fixed in the blade chamber soldered on the blade shaft, the blade chamber is in 6-24 equilibrium along the circumferential orientation of the shaft, and are staggered along the axial direction of the shaft, the soil scraping board and the blade shaft have the similar length with the number of 2-6, and are uniformly distributed on the circumferential direction of the blade shaft, the stubble burying blade is in double arced shape with a sliding cutting angle of 1-10 deg.

Description

technical field [0001] The invention relates to a farmland tillage machine, in particular to a stubble tillage machine which can be used for both water and drought and which integrates rotary tillage, stubble burying and harrowing. Background technique [0002] In order to improve the soil performance of cultivated land and avoid the pollution caused by straw burning, it is the best solution to implement "straw returning to the field". The development of efficient and applicable plowing and stubble-burying machinery is an important issue to be solved urgently in the field of agricultural machinery. Although the existing paddy field rakes, paddy field stubble burying and paddy soil preparation machines and double-roller stubble removal and soil preparation machines can play the role of plowing and stubble burial to varying degrees, there are the following major defects: 1. Paddy field rakes and paddy field burying machines. The stubble pulping and soil preparation machine ca...

Problems solved by technology

Although the existing paddy field rakes, paddy field stubble burying and paddy soil preparation machines and double-roller stubble removal and soil preparation machines can play the role of plowing and stubble burial to varying degrees, there are the following major defects: 1. Paddy field rakes and paddy field burying machines. The stubble pulping and soil preparation machine can only work on the cultivated land, that is, the wheat field must be plowed once, soaked in water for 12 hours before the machine can be used for operation. There are many farming links and the cost of farming is high.

2. Although the two-roller stubble removal and soil preparation machine can work on uncultivated land, because it is a dual-axis cutter roller (rotary tillage on the front shaft and stubble removal on the rear shaft), the structure is complex, the load is heavy, and the operating cost is high; Due to the limitation of the structure of the roller assembly, the machine can only complete plowing, stubble burial, soil breaking, pulping, and leveling operations in paddy fields at one time. When operating in dry land, the effect is poor. In addition, the stubble cutter roller In the assembly, the arc scimitar is directly welded on the cutter shaft, which is not conducive to maintenance and replacement
