Specific embodiment
Present invention is further described in detail with reference to the accompanying drawing:
Attached drawing 1 first illustrates one kind and takes off grain header structure.It includes housing 1, grain-pushing equipment 2, protective fence 3 that this, which takes off grain head mainly,
With mechanical limiting mechanism 4.The whole arc-shaped frame of protective fence 3 or Arc grid shape, are divided into rotatable multi-segment structure, pass through set
If shaft and be movably arranged on 2 bracket of grain-pushing equipment (or housing 1).Mechanical limiting mechanism 4 utilizes housing 1 and protective fence 3
Structure is installed.Grain-pushing equipment 2 is mounted in housing 1 and protective fence 3, using opposed bipacking-auger structure.
As shown in Fig. 2, mechanical limiting mechanism 4 of the invention mainly includes limit switch 7, compressed spring 8, spring guiding
Bar 9, fixing seat 11, adjusts head 12, locking nut 13, limit switch connecting plate 14 at Contact plate 10.Wherein, spring conductor rod 9 one
End is equipped with end cap, 8 sets of compressed spring on spring conductor rod 9, and by adjust head 12 and locking nut 13 be fixed on end cap and
Between fixing seat 11.Head 12 is adjusted to be fixed in fixing seat 11 by locking nut 13, spring conductor rod 9 pass through adjust head 12,
Locking nut 13, fixing seat 11, the other end are pierced by fixing seat 11.Limit switch 7 is fixed on by limit switch connecting plate 14
The side of reservation 11.Contact plate 10 is in polyline shaped, and one end of which is fixed on the outside of end cap, the other end is hanging and stretches to limit switch 7.
Connection between limit switch 7 and limit switch connecting plate 14 can use the form of bolt and nut cushioning circle, and limit switch connects
It is fixed between fishplate bar 14 and fixing seat 11 by screw two (hexagon socket cap head screw) 15.
Referring to attached drawing 3 and 4, it is shown that mechanical limiting mechanism 4 of the invention is connected to protective fence 4 (or one section of protective fence)
On.One end that spring conductor rod 9 stretches out fixing seat 11 is connected with connecting plate 17 by pivot pin.Shaft 18 penetrates rotatably
Connecting plate 17.
Each section of protective fence 3 includes at least 18, two swing links 19 of a shaft and a detection collision bar 20.Shaft
18, detection collision bar 20 is horizontally fixed between two opposed swing links 19 of left and right.
Fixing seat 11 has welding pedestal 16, and mechanical limiting mechanism 4 of the invention is mounted on cover by the welding pedestal 16
On shell 1.Welding pedestal 16 is fixed on housing 1 by screw 1, or replaces with bolt and nut fixed form.
In the present invention, a mechanical limiting mechanism 4 is all connected on each section of protective fence 3, multistage protective fence can share one
