Face 6 is a curved surface.
The outer surface of the active section 4 of the spike-tooth main body 1 is socketed a rubber sleeve 2 corresponding with the shape of active section 4.
The thickness D of spike-tooth main body 1 is 8~16mm；The width L of spike-tooth main body 1 is 10~12mm；The height H of spike-tooth main body 1
For 70~120mm, wherein active section 4 accounts for the 40%~50% of 1 height of spike-tooth main body, remaining is fixed section 5；The worksheet
The subsequent corrosion R in face 6 is 55~60mm, and the curved surface arc length l of working surface 6 is 45~50mm；The rubber sleeve 2 with a thickness of 3
~6mm.
Preferably, the thickness D of spike-tooth main body 1 is 10mm；The width L of spike-tooth main body 1 is 11mm；The height H of spike-tooth main body 1
For 100mm, wherein active section 4 accounts for the 45% of 1 height of spike-tooth main body, remaining is fixed section 5；The curved surface of the working surface 6 half
Diameter R is 57mm, and the curved surface arc length l of working surface 6 is 47mm；The rubber sleeve 2 with a thickness of 4mm.
Compared with prior art, the beneficial effects of the present invention are:
The body top of corn kernel harvester threshing spike-tooth of the invention uses curved design, can be quickly to corn fruit
Fringe carries out threshing；Outer cover rubber sleeve simultaneously, can be effectively reduced impact force of the spike-tooth in threshing course to corn kernel, drop
The seed breakage rate of low corn kernel harvest process.

Specific embodiment
Invention is further explained with reference to the accompanying drawings and examples.
As shown in Fig. 2, a kind of corn kernel harvester threshing spike-tooth, including spike-tooth main body 1 and rubber sleeve 2.
As shown in Figure 3 and Figure 4, the spike-tooth main body 1 is with certain thickness plate tooth comprising the active section on top
4 and lower part fixed section 5；The fixed section 5 is removably fixed on the threshing cylinder of corn kernel harvester, so that spike-tooth
The thickness end face of main body 1 is arranged along the rotation direction of threshing cylinder；The active section 4 of the spike-tooth main body 1 connects with corn ear
It touches and is working surface 6 to the side thickness end face that corn ear applies active force, which is a curved surface.
The thickness D of the spike-tooth main body 1 is 8~16mm, preferably 10mm；The width L of the spike-tooth main body 1 be 10~
12mm, preferably 11mm；The height H of spike-tooth main body 1 is 70~120mm, preferably 100mm；Wherein, active section 4 accounts for spike-tooth master
The 40%~50% of 1 height of body, preferably 45%, remaining is fixed section 5；The subsequent corrosion R of the working surface 6 be 55~
60mm, preferably 57mm, the curved surface arc length l of working surface 6 are 45~50mm, preferably 47mm.
The outer surface of the active section 4 of the spike-tooth main body 1 is fixedly attached the shape of one Yu active section 4 by fastening bolt 3
Corresponding rubber sleeve 2.The rubber sleeve 2 with a thickness of 3~6mm, preferably 4mm.
The body top of corn kernel harvester threshing spike-tooth of the invention uses curved design, can be quickly to corn fruit
Fringe carries out threshing；Impact force of the spike-tooth in threshing course to seed can be effectively reduced in outer cover rubber sleeve simultaneously, reduces seed
The seed breakage rate of grain harvest process.
It the use of lateral bending power is to keep corn ear de- to corn ear according to mechanical characteristic of the corn kernel on fruit ear
The best mode of grain, the lateral bending power can Orthogonal Decomposition be to the normal force and tangential force of corn ear.As shown in figure 5, this
The threshing spike-tooth of invention is compared with traditional threshing spike-tooth, obvious to the normal force of corn ear in practical corn ear threshing
It reduces, tangential force obviously increases.
