Description
Technical field
The utility model belongs to agricultural mechanical field, is related to rotary cultivator rotary tillage tool magazine, and especially a kind of rotary cultivator is special
The antiwind rotary blade assembly of high intensity.
Background technology
The rotary blade assembly being made up of rotary tillage cutter shaft, rotary tillage tool magazine and rotary blade is the important spare part of rotary cultivator, is being dragged
Under the traction of machine drawing, the rotary tillage cutter shaft on rotary cultivator carries out hack operation, and the weight of supporting machine, is also responsible for driving rotary cultivator
Traveling.
Traditional rotary blade assembly, its rotary tillage tool magazine is rectangle, is fixed on cutter shaft surface by welding manner, and pass through spiral shell
Bolt is connected with rotary blade setting-in, referring to Fig. 4,5,6.In operation, traditional rotary tillage tool magazine is in operation, and its stress surface is in level
State and various plants and plastic sheeting are constantly wrapped in tool magazine and cutter hub in tool magazine working face, soil all the time
On, and can be more and more, and roll bigger and bigger with the guild of entering of operation, not only greatly consume power and also have a strong impact on
Operation quality, is cleared up so that operator must not infrequently shut down and influences operating efficiency.Therefore, traditional rectangle rotary tillage
Tool magazine, although processing technology is simple, and manufacturing cost is cheap, but there is the critical defect for easily winding and causing weld seam to snap.
For a long time, people simply have carried out going deep into systematic research to rotary blade assembly.It such as have studied rotary blade work
The slip cutting angle for making surface curve is how to cut soil etc., but the research of the tool magazine to being attached thereto does not have excessive concern.
By the retrieval of patent document, following two patent documents related to present patent application are found：
1st, a kind of hard place bispin ploughs tool magazine (CN203951739U), and its basic structure includes setting double rotary blade fixing holes
Tool magazine body, bispin is ploughed on tool magazine body and sets screw jack respectively, it is characterised in that：Bispin is set to plough tool magazine body, it is welded with cutter shaft
Junction sets arc adjutage.The rotary blade insertion end face of the tool magazine body is provided with reinforcement.The skill that the utility model is used
Art scheme is compared with existing rotary tillage tool magazine, and its technological progress effect is shown：Add the solder side in double-pole storehouse, tool magazine and cutter shaft
Increase, is welded and fixed tool magazine more firm；Reinforcement is set on rotary tillage tool magazine outer；Arc shovel is provided with before and after double-pole storehouse,
Can divide soil during rotary tillage process, reduce knife and tool magazine stress, be further increased tool magazine by force intensity, effectively extend rotary tillage
The service life of tool magazine.
2nd, the rotary tillage tool magazine (CN204906990U) of a kind of soil subsoiling machine of working soil, rotary tillage tool magazine one end is along rotary tillage cutter shaft axle
To uniformly at intervals, Rotary tillage blade is arranged on the rotary tillage tool magazine other end；The root of rotary tillage tool magazine to be square, for rotary tillage cutter shaft
Coordinate and install, the side of rotary tillage tool magazine is moon knife.The utility model is combined by square storehouse with moon knife, and rotary cultivator is in work
When, the moon knife on tool magazine is cut to soil, reduces the soil-entering resistance of tool magazine, so as to reduce the farming resistance of rotary cultivator
Power；Install moon knife on tool magazine additional, an integral cutting cutter is formd with rotary blade, not only can to earth's surface weeds and stalk
Fully chopping, meanwhile, cutting section does not leave dead angle, and corn stubble and the maize straw remained in earth's surface are played well
Chopping is acted on, and the quality after rotary tillage process can meet agriculture requirement, improve rotary tillage quality and operating efficiency.
By the reading to above-mentioned two patent documents, applicant thinks：Although above-mentioned patent document 1 devises reinforcement
Muscle, but the reinforcement face of the reinforcement is different from present patent application, and also involved rotary tillage tool magazine is double-pole storehouse；As for patent text
2 are offered, is only the combining structure for having innovated square tool magazine and moon knife, is differed with present patent application in general structure.Therefore,
Above-mentioned two patent documents will not destroy the creativeness of present patent application.
