Currently, corn kernel harvester still uses traditional threshing spike-tooth.As shown in Figure 1, traditional threshing spike-tooth is in ladder Shape is flat-shaped, and material is metal rigidity material, big to the impact force of corn kernel when carrying out corn ear threshing, easily causes jade Rice seed damage, especially in the case where corn kernel moisture content is higher, breakage rate is higher, influences corn kernel harvester Whole harvest effect;For traditional threshing spike-tooth in threshing, the contact with corn ear is a line, is increased to corn ear Effect pressure, easily make corn kernel damaged.
Summary of the invention
It in view of the above technical problems, can be fast the object of the present invention is to provide a kind of corn kernel harvester threshing spike-tooth Speed carries out threshing to corn ear, and when carrying out grain harvest to the higher corn ear of moisture content, can reduce corn The breakage rate of seed.
To achieve the goals above, the present invention provides the following technical scheme that
The present invention provides a kind of corn kernel harvester threshing spike-tooth, which includes spike-tooth main body 1 and rubber sleeve 2。
The spike-tooth main body 1 is with certain thickness plate tooth comprising the active section 4 on top and the fixed section of lower part 5;The fixed section 5 is removably fixed on the threshing cylinder of corn kernel harvester, and the thickness end face of spike-tooth main body 1 is along de- The rotation direction setting of grain roller;The side thickness end face of the active section 4 of the spike-tooth main body 1 is working surface 6, the worksheet 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.
