Description

Stubble removal rotary tillage machine transmission mechanism

technical field

The utility model belongs to agricultural machinery, and mainly relates to a stubble removal and rotary tillage implement.

Background technique

The stubble removal rotary tillage and land preparation machine is one of the important machines for dry field land preparation in northern my country, and has played an active role in agricultural production. However, on the existing stubble removal rotary tillage soil preparation machine, the driving power of the stubble removal cutter shaft and the rotary tiller shaft is all transmitted through a main transmission box on the machine tool, resulting in a large load of the main transmission box, heavy wear, and easy damage. The use durability is reduced; in addition, the stubble cutter shaft transmission box that transmits power from the main transmission box to the stubble cutter shaft has many transmission gears, the size of the box is large, the weight increases, the manufacturing cost of the machine tool is high, the transmission efficiency is low, and the power loss is large; Third, the subsoiling ridge-breaking shovel assembly and the stubble removal cutter shaft on the existing equipment are fixed on the same frame assembly, and the distance between them is relatively close, the distance is small, the overall configuration is difficult, and root stubble and stubble are prone to occur during operation. The blockage of straw, weeds and clods will affect the operation efficiency and quality.

Contents of the invention

The purpose of this utility model is to solve the problems existing in the above-mentioned prior art, and to design and provide a transmission mechanism of a stubble-removing rotary tillage machine with a new structure, so as to reasonably distribute the driving power load, reduce wear and tear of the transmission system, prolong the service life of the equipment, reduce failures, The purpose of reducing the weight of the machine tool and improving the transmission efficiency.

The basic design of the utility model is that the front crossbeam is fixed on the front part of the frame assembly, and the stubble cutter shaft is fitted on the front crossbeam, located below the front crossbeam; The central gearbox composed of small bevel gear and large bevel gear is assembled. The small bevel gear is fixed on the I shaft, and the large bevel gear is fixed on the II shaft. The small bevel gear and the large bevel gear are constantly meshed; The coupling on the front end of the power input shaft of the rotary tillage shaft gearbox is connected; the stubble removal shaft transmission box is installed on one side of the front beam, and the power input shaft on the upper side of the stubble removal shaft transmission box and the power output shaft on the lower side It is respectively connected with one end of the universal joint transmission shaft and one end of the stubble removal cutter shaft, and the other end of the universal joint transmission shaft is connected with the II shaft of the central gearbox, thus forming the transmission mechanism of the stubble removal rotary tiller.

The utility model adopts the technical scheme of adding a central gearbox, and then the central gearbox divides the driving power through the rotary shaft gearbox and the stubble removal shaft transmission box to drive the rotary tiller shaft and the stubble removal shaft respectively, which overcomes the above-mentioned prior art. Various defects exist, the distance between the deep loosening ridge breaking shovel assembly and the stubble cutter shaft is increased, the operation process is not blocked, the structure is simple and novel, the overall configuration is scientific and reasonable, the driving power load is evenly distributed, and the service life of the machine tool is long. The characteristics of high transmission efficiency and less operation failure.
