Abstract
The invention belongs to agricultural machinery technology fields, provide a kind of anti-dropout rotary blade fixed structure.The structure is mainly made of rotary blade, tool magazine backplate, tool magazine side panel a and tool magazine side panel b.In the present invention, rotary blade resistance suffered when working will make rotary blade more more slotting tighter in tool magazine, and the fixation torque arm length of tool magazine is approximately the length of tool magazine backplate, it can accomplish 34 times or more of rotary blade width, the resistance of similary 100kg, the tensile stress generated at the fixed arm of force only has 300 600kg, and 1/3 1/4 of tensile stress at the arm of force is fixed for traditional rotary blade fixed structure.Therefore requirement to fixed structure intensity is greatly lowered, and the positioning screw in the present invention actually only plays the role of positioning, and do not stress, therefore also unexpected is come off.It replaces easy to maintain, such as needs to change rotary blade, it is i.e. replaceable only to back-out positioning screw.
Description
Technical field
The invention belongs to agricultural machinery technology fields, and in particular to a kind of anti-dropout rotary blade fixed structure.
Background technology
Rotary cultivator be complete to plough with tractor, the cultivation machinery of rake operation, because its with hack ability it is strong, plough after ground
The features such as table is flat, and be widely used.Rotary tillage mechanism on existing mainstream rotary cultivator is all a horizontal rotation
Axis welds the tool magazine perpendicular to rotating shaft surface on the rotary shaft, by rotary blade perpendicular to rotating shaft surface, along rotary shaft radial direction
Direction is inserted into tool magazine and is locked with trip bolt across mounting hole, by driven by engine rotary shaft rotary work.In actual production
In, it is this unsatisfactory along the fixed form effect of rotary shaft radial direction perpendicular to rotating shaft surface, when by ploughing and weeding object
Hardness is larger or when depth is deeper, and rotary blade can come off often, and even tool magazine can also come off sometimes.
Invention content
It is not only not easily to fall off the purpose of the present invention is inventing a kind of more firm rotary blade fixed form, and repair
It is convenient to replace.
Technical scheme of the present invention：
A kind of anti-dropout rotary blade fixed structure, mainly by rotary blade 1, tool magazine backplate 3, tool magazine side panel a4 and tool magazine
Side panel b5 is formed；The radian of the fixing end of the rotary blade 1 and rotation shaft section and the rotary blade fixed structure assembled
Radian cooperation, be provided with semicircle rotary blade locating notch 2 on fixed end margin；The tool magazine backplate 3 is rectangle face
Plate, the width of backplate 3 are identical with the thickness of rotary blade 1；The tool magazine side panel a4 is surrounded by a circular arc and two straight lines,
The radian of circular arc is identical with the circular arc of rotary shaft outer surface, and positioning round orifice a41 is provided on tool magazine side panel a4；The tool magazine side
The shape of panel b5 is consistent with tool magazine side panel a4, and positioning round orifice b51 is provided on tool magazine side panel b5；The tool magazine side panel
The straight line of a4 and tool magazine side panel b5 are fixed on 3 both sides of tool magazine backplate, and are welded into an entirety；Tool magazine side panel a4
With the arc-shaped edges of tool magazine side panel b5 and rotating shaft surface full weld；The fixing end insertion tool magazine side panel a4 of the rotary blade 1,
In the gap that tool magazine side panel b5, tool magazine backplate 3 and rotating shaft surface are formed, positioning round orifice is sequentially passed through with positioning screw
A41, rotary blade locating notch 2 and positioning round orifice b51 block rotary blade locating notch 2, form anti-dropout rotary blade fixed knot
Structure.
The both sides of the tool magazine backplate 3 are provided with multiple tooth mouths；The tool magazine side panel a4, wherein straight line side
On be provided with multiple square holes, matched with the tooth mouth of tool magazine backplate 3；The tool magazine side panel b5, wherein on straight line side
Multiple square holes are provided with, are matched with the tooth mouth of tool magazine backplate 3；The tooth mouth of 3 both sides of tool magazine backplate is inserted into knife respectively
In the square hole of library side panel a4 and tool magazine side panel b5, and it is welded into an entirety.
The invention has the advantages that：Original rotary blade fixed form is compared, why former rotary blade easily comes off,
Main reason is that when rotary blade is fixed perpendicular to rotating shaft surface, the torque arm length for the resistance being subject to is that rotary blade is long
Degree, and tool magazine to rotary blade rise fixed function fixation torque arm length be only rotary blade width, for general rotary blade,
Its length is 10-20 times of its width or more, it is assumed that resistance reaches 100kg, then fixes the tensile stress generated at the arm of force and be up to
More than 1000-2000kg, so easily coming off during continuous work.And in the present solution, rotary blade is suffered when working
Resistance rotary blade will be made more more slotting tighter in tool magazine, and the fixation torque arm length of tool magazine of the present invention is approximately the tool magazine back side
The length of plate can accomplish 3-4 times or more of rotary blade width, and the resistance of similary 100kg, the drawing generated at the fixed arm of force should
Power only has 300-600kg, and the 1/3-1/4 of tensile stress at the arm of force is fixed for traditional rotary blade fixed structure.Therefore to fixed structure
The requirement of intensity is greatly lowered, and the positioning screw in this programme actually only plays the role of positioning, and does not stress, therefore also unexpected de-
It falls.It replaces easy to maintain, such as needs to change rotary blade, it is i.e. replaceable only to back-out positioning screw.
