Abstract
The utility model discloses a combined-knife rotary blade free of twining grass. The combined-knife rotary blade free of the twining grass is used for farmland ploughing and preparation machine, and comprises a rotary blade shaft, a tool changer, a rotary blade body and a secondary blade. The tool changer is formed by a main changer piece and a secondary changer piece in a welded mode, wherein edges are arranged on the two sides of the main changer piece and play a role in reinforcing ribs at the same time, the tool changer is welded to the rotary blade shaft, a knife handle of the rotary blade body is inserted into the tool changer, and is fastened through a bolt and a nut, and the secondary blade is welded to one side of the cutting edge of the rotary blade body of the main changer piece. Due to the combination between the rotary blade body and the secondary blade, when a rotary cultivator works, an integral cutting edge is formed from the tool nose of the rotary blade body to the rotary blade shaft, straw is cut off, the problems that an ordinary rotary blade is twined by the grass, and operation efficiency is reduced are solved, and meanwhile due to the fact that the novel tool changer structure enables the strength of the tool changer to be higher, the frequency of open weld of an ordinary tool changer in the process of use is reduced.
Description
Technical field
The utility model relates to agricultural land tillage machine tool parts, is specifically related to rotary tillage, buries a batch Work machine straw winding combination cutter rotary blade.
Background technology
It is in the agricultural production of land for growing field crops to be substantially the most also one of most important working link that farmland is ploughed whole, at present, be mainly rotary tilling-type machinery in the agricultural land tillage machine tool, rotary tillage is the blade cut of utilizing rotovator rotation, break up the clods, loose a kind of expedient of tillage of puddling topsoil, its operating efficiency is very high, has become mainstream model.Along with the application of wideling popularize of straw-returning technology in recent years, field straw, weeds quantity increase, and make in the ploughing operation of farmland and have run into new problem.
Rotary blade is the vitals of ploughing machine, the rotary blade of ploughing machine use at present, and weeds or stalk often can be wrapped on rotary ploughing cutter shaft when operation, and the general job maximum two hours just must be removed rotary ploughing cutter shaft, has a strong impact on farming efficiency.
Summary of the invention
The purpose of this utility model is: a kind of straw winding combination cutter rotary blade is provided, and grass-wrapping problem while solving the ploughing machine operation, make the tool magazine welding procedure more reasonable with stylish magazine tool structure, and tool magazine intensity is higher, reduces in common tool magazine use and snaps problem.
Technical solution of the present utility model is: the utility model straw winding combination cutter rotary blade consists of rotary ploughing cutter shaft, tool magazine, rotary blade and secondary cutter.Described tool magazine is welded by master library sheet, secondary storehouse sheet, the wherein master library sheet both sides band edge reinforcement effect of having held concurrently, tool magazine is pressed the different model harvesting and tillage machine to rotary blade quantity and arrangement requirement, be welded on the rotary ploughing cutter shaft relevant position, the rotary blade handle of a knife is inserted in tool magazine, fastening by bolt and nut, secondary cutter is welded on rotary blade blade one side of master library sheet.The utility model is due to the combination of rotary blade and secondary cutter, during the rotovator operation, form complete cutting edge from the rotary blade point of a knife to rotary ploughing cutter shaft, stalk is cut off, solve common rotary tillage cutter and twined the careless problem that affects operating efficiency, make tool magazine intensity higher with stylish magazine tool structure, reduce in common tool magazine use and snap problem.
The utlity model has following advantage:
The utility model straw winding combination cutter rotary blade,, due to the combination of rotary blade and secondary cutter, during the rotovator operation, form complete cutting edge from the rotary blade point of a knife to rotary ploughing cutter shaft, stalk is cut off, solved common rotary tillage cutter and twined the careless problem that affects operating efficiency.New magazine tool structure, tool magazine is stuck in the master library sheet and is welded by secondary storehouse sheet, and welding procedure is more reasonable, and weld strength is higher.Master library sheet both sides band trapezoidal side, the reinforcement effect of having held concurrently, further increase tool magazine intensity.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is tool magazine of the present utility model and secondary knife structure figure.
In figure: 1, secondary cutter, 2, rotary blade, 3, tool magazine, 4, bolt, 5, nut, 6, rotary ploughing cutter shaft, 7, the master library sheet, 8, secondary storehouse sheet.
Embodiment
As shown in Figure 1-2, the utility model straw winding combination cutter rotary blade consists of rotary ploughing cutter shaft (6), tool magazine (3), rotary blade (2) and secondary cutter (1).Described tool magazine (3) is stuck in master library sheet (7) and is welded by secondary storehouse sheet (8), and welding procedure is more reasonable, and weld strength is higher.Master library sheet (7) both sides band trapezoidal side, the reinforcement effect of having held concurrently, further increase tool magazine (3) intensity.Tool magazine (3), by quantity and the position of the requirement of different shaped machinery, is welded on rotary ploughing cutter shaft (6).The handle of a knife of rotary blade (2) is inserted in respectively in each tool magazine (3), and is fastening by bolt (4) nut (5).Secondary cutter (1) is welded on rotary blade (2) blade one side of master library sheet (7).The present invention is due to the combination of rotary blade (2) and secondary cutter (1), during the rotovator operation, form complete cutting edge from the rotary blade point of a knife to rotary ploughing cutter shaft, stalk is cut off, solve common rotary tillage cutter and twined the careless problem that affects operating efficiency, make tool magazine intensity higher with stylish magazine tool structure, reduce in common tool magazine use and snap problem.
Claims (1)
1. a straw winding makes up the cutter rotary blade, structure comprises rotary ploughing cutter shaft, tool magazine, rotary blade and secondary cutter, it is characterized in that: tool magazine is welded by master library sheet, secondary storehouse sheet, the wherein master library sheet both sides band edge reinforcement effect of having held concurrently, tool magazine, is welded on the rotary ploughing cutter shaft relevant position rotary blade quantity and arrangement requirement by the different model harvesting and tillage machine, and the rotary blade handle of a knife is inserted in tool magazine, fastening by bolt and nut, secondary cutter is welded on the rotary blade blade one side side of master library sheet.
