Technical field

The utility model belongs to an agricultural machine tool, in particular to a hanging rotary tillage, stubble removal and grass burying rake suitable for protective tillage.

Background technique

Soil tillage machinery is an important agricultural machine tool in agricultural production. Its tasks are to improve the soil structure, bury weeds and crop residues, organize the surface shape, and suppress loose soil. Soil tillage machinery is generally divided into ploughshare tillage machinery, disc tillage machinery, soil preparation machinery, subsoiling machinery, drive tillage machinery, etc. according to the structural form. According to the power mode, it can be divided into self-propelled tillage machinery, drive tillage machinery and traction tillage machinery, among which drive tillage machinery has been formed in modern agricultural production. An emerging type of agricultural implement.

Existing driven tillage machines mainly include curved-blade scimitar rotary tillers, right-angle scimitar rotary tillers, etc. These agricultural implements can complete soil cultivation and finishing operations, with good work quality and high efficiency. The working farmland has certain working conditions, such as soil firmness, soil moisture content, crop residues and weed properties and distribution density, etc. It is impossible to turn over the upper and lower layers of soil, stubble and throw, bury weeds, and suppress moisture. There are also problems such as large power consumption.

At present, the state advocates the joint operation and duplex operation of agricultural machinery and tools to improve the utilization rate of machinery and reduce production costs; in consideration of environmental protection and water-saving irrigation, farming methods such as conservation tillage and straw returning to the field are advocated. Develop a machine tool that integrates plowing, stubble removal, grass burying, and suppression. It can continue to develop in the direction of compound agronomic operations, conservation tillage, and power consumption reduction, so as to meet the current agronomic requirements of conservation tillage and soil preparation. The rotary tillage harrow integrates plowing and suppression, which can achieve the turning of the upper and lower layers of soil, complete the agronomic operation of the upper and lower solid soil surface, and increase the functions of stubble removal and grass burying, which is beneficial to the storage of water and moisture in the farmland and the transformation of organic matter. The utility model belongs to a new type of agricultural machinery which is energy-saving and environment-friendly. Rotary tillage harrow can improve the operating efficiency of agricultural machinery, reduce power consumption, reduce operating costs, and meet the requirements of agronomy. It has broad application prospects and has great practical significance for the development of agricultural mechanization in my country.

Contents of the invention

There are 3 side scimitar fixing grooves on each side of the center spoke of the knife roll, and there are 6 side scimitar fixing grooves on both sides. The centers of adjacent side scimitar fixing grooves are separated by 60°. There is a fixing hole, and the inner hole of the spoke disc shaft is arranged in the center of the spoke disc of the cutter roll. The middle part of the knife roller shaft is a thick-walled steel pipe, and the two ends are respectively welded with an inner spline shaft head and a shaft head. The two side spokes of the knife roll are respectively fixed on both ends of the knife roll shaft through the inner hole of the spoke disc shaft, the middle spoke disc of the knife roll is fixed on the middle of the knife roll shaft through the inner hole of the spoke disc shaft, and the side scimitar is fixed on the side of the knife roll The side scimitars of the spoke disk and the center-spoke disk of the knife roll are fixed in the fixing grooves and fastened with fastening bolts through the fixing holes. Helical distribution, the horizontal knife plate is welded on the side scimitar on the side spoke disc of the knife roll and the side scimitar on the middle spoke disc of the knife roll, and forms an angle of 40° with the knife roll axis, thus reducing the number of plowing and rake combined knife rolls 3 vertical knives are evenly distributed on the working surface of the horizontal knife plate, and the anti-wrap edge knife is welded on the outside of the curved knife on the upper side of the side spoke of the knife roll.

When the hanging rotary tillage stubble removal and grass burying harrow is operated, firstly, the depth-limiting wheel is adjusted to the specified plowing depth according to the agronomic requirements through the tillage depth adjustment mechanism. The power output of the input drive shaft drives the reduction gear box and the middle transmission box to drive the left and right two groups of plowing and rake combination knife rolls to move forward in the same direction as the same unit. Cutting on the side cutting edge, and then gradually shift to cutting on the side cutting edge farther away from the roller axis of the knife; the horizontal knife and the anti-wrapping knife with a straight edge cut the soil block from the positive slope, cut out a flat ditch bottom and cut off the side cutting edge The crop residues and weeds that are not cut, or the crop residues and weeds are pushed outward, and the horizontal blade will gradually change from point-cut buried crop residues and weeds to line-cut buried crop residues according to its spatial movement trajectory At the same time, the curved vertical knife repeats the cutting process of the side curved knife, most of the crop residues and weeds are cut off, and the uncut crop residues and weeds are also cut deep by the change of the curved edge. Buried or thrown from the end of the cutting edge, the next set of horizontal blades and vertical knives will cut again; the anti-wrap edge knives will continuously remove the crops that are wound on the knife roller during the rotation of the plow and harrow combination knife. The stubble and weeds are shredded and thrown outward; the combination of rake and knife roll throws the cut soil backwards, hits the casing and drag plate and is crushed, and then falls back to the surface to cover the scattered crops The stubble and weeds, the rear drag plate and the pressing roller assembly are driven by the tension spring damper, and the random group will level and suppress the plowed soil through parallel motion. The hanging rotary tillage and stubble burying rake can complete agronomic complex operations such as plowing, stubble removal, grass burying, and suppression in the tilling process at one time.

The utility model has the advantages of the hanging type rotary tillage and stubble burying rake: a disc-type tillage harrow combination knife roll is designed to replace the traditional rotary tillage scimitar combination, which solves the problem that traditional tillage machines cannot rotary tillage hard soil, stubble removal and Due to problems such as burying grass, inability to carry out compound operations, and high power consumption, working components such as tension spring dampers and pressing roller assemblies are added to better complete the leveling and pressing of the soil, and can complete the plowing during the tilling process at the same time. Rake, stubble removal, grass burying, suppression and other agricultural complex operations, thereby improving the working efficiency of the machine and reducing power consumption. The hanging rotary tillage stubble removal rake has the characteristics of high working efficiency and low operating cost, and has a reasonable structure, low power consumption, and meets the needs of protective tillage. It is a new type of energy-saving and environmentally friendly agricultural machinery and has broad application prospects.
