Abstract
The invention discloses a combined-cutter rotary blade free of grass twining used for farmland plough and preparation machinery. The combined-cutter rotary blade free of grass twining comprises a rotary blade shaft, a cutter changer, a rotary blade body and an auxiliary cutter. A primary changer piece and a secondary changer piece are welded to form the cutter changer. The primary changer piece is provided with edges on two sides and serves as a reinforcing rib. The cutter changer is welded on the rotary blade shaft. A handle of the rotary blade is inserted in the cutter changer, and is fixed through a bolt and a nut. The auxiliary cutter is welded on one side of a cutting edge of the rotary blade of the primary changer piece. Due to combination of the rotary blade and the auxiliary cutter, when a rotary cultivator works, an integrated cutting edge is formed form a point of the rotary blade to the rotary blade shaft to cut off straws, so that the problem that working efficiency is affected due to the fact that grass twines on common rotary blades is solved, strength of the cutter changer is high through a new cutter changer structure, and breakage during usage of common cutter changers is reduced.
Description
Technical field
The present invention relates to farmland harvesting and tillage machine tool parts, be specifically related to rotary tillage, bury a batch Work machine straw winding combination cutter rotary blade.
Background technology
It is substantially the most also to be one of most important work link in the agricultural production of land for growing field crops that the farmland is ploughed whole, at present, be mainly rotary tillage formula machinery in the harvesting and tillage machine tool of farmland, rotary tillage is to utilize the rotovator rotation of blade to cut, break up the clods, loosen and puddle a kind of expedient of tillage of 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 stalk, weeds quantity heighten, and make in the ploughing operation of farmland to have run into new problem.
Rotary blade is the vitals of harvesting and tillage machine tool, the rotary blade of harvesting and tillage machine tool use at present, and weeds or stalk regular meeting are wrapped on the 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 efficient.
Summary of the invention
The objective of the invention is to: a kind of straw winding combination cutter rotary blade is provided, and grass-wrapping problem when solving the operation of harvesting and tillage machine tool makes the tool magazine welding procedure more reasonable with stylish tool magazine structure, and tool magazine intensity is higher, reduces in the common tool magazine use and snaps problem.
Technical solution of the present invention is: straw winding combination cutter rotary blade of the present invention is made 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, and tool magazine is welded on the rotary ploughing cutter shaft, and the rotary blade handle of a knife is inserted in the tool magazine, and is fastening by bolt and nut, and secondary cutter is welded on rotary blade blade one side of master library sheet.The present invention is because 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 problem that grass influences operating efficiency, make tool magazine intensity higher with stylish tool magazine structure, reduce in the common tool magazine use and snap problem.
The present invention has the following advantages:
Straw winding combination cutter rotary blade of the present invention because the combination of rotary blade and secondary cutter during the rotovator operation, forms complete cutting edge from the rotary blade point of a knife to rotary ploughing cutter shaft, cuts off stalk, has solved common rotary tillage cutter and has twined the problem that grass influences operating efficiency.New tool magazine structure, tool magazine is stuck in the master library sheet by secondary storehouse sheet and is welded, 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 increases tool magazine intensity.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is tool magazine of the present invention and secondary knife structure figure.
Among the 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
Shown in Fig. 1-2, straw winding combination cutter rotary blade of the present invention is made of rotary ploughing cutter shaft (6), tool magazine (3), rotary blade (2) and secondary cutter (1).Described tool magazine (3) is stuck in the master library sheet (7) by secondary storehouse sheet (8) and is welded, 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 increases tool magazine (3) intensity.Tool magazine (3) is welded on the rotary ploughing cutter shaft (6) by quantity and the position of the requirement of different shaped machinery.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 because 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 problem that grass influences operating efficiency, make tool magazine intensity higher with stylish tool magazine structure, reduce in the 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 the tool magazine, fastening by bolt and nut, secondary cutter is welded on the rotary blade blade one side side of master library sheet.
