Abstract
The de- plate tooth of the general comb of boomerang type spoon shape semicircular arc spoon side rice and kernel belongs to agricultural machinery；The top end part that boomerang type spoon shape combs de- plate tooth is integrally tapered, combs in the boomerang type spoon shape and evagination semicircular arc spoon side is arranged on the outside of the spoon body for taking off plate tooth on spoon edge position, and the arc radius size R on the evagination semicircular arc spoon side is 1.5-2.5 millimeters；This plate tooth solves the technical issues of must reversely installing and using when current boomerang type spoon shape combs larger operation resistance existing for de- plate tooth, comb dehydration rice crops, has the characteristics that structure novel, simple, reasonable, easy to install and use, strong applicability, operation quality are good, high-efficient, power consumption is few.
Description
Technical field
The invention belongs to agricultural machinery, relates generally to a kind of rice and wheat threshing combs de- plate teeth portion part.
Background technique
It is plate-like structure that traditional boomerang type rice and kernel, which combs de- plate tooth, when carrying out rice-wheat threshing stripping work, due to flat
Plate structure takes off rice and kernel seed without bunched function to comb, and seed running track is unable to control, and to the thrust of seed
The acceleration time is short, and it is big to there is a problem of that rice and kernel seed separates difficulty, grain loss rate with stalk.In recent years, a kind of boomerang type spoon
Shape rice and kernel is combed de- plate tooth and is researched and developed successfully in foreign countries, solves above-mentioned conventional flat plate boomerang template tooth.But
The globular model structure of boomerang type spoon shape plate tooth tip portion and the planar structure on spoon body periphery, and plate tooth insertion rice when producing stripping work
Wheat head head internal resistance is larger, power consumption is more, combs the problem of de- effect difference, need to be on equipment especially when harvest combs dehydration rice
Reversed installation spoon shape combs de- plate tooth, inconvenient for use, and operating efficiency declines to a great extent, poor for applicability, otherwise will cause rice grain
Glume is broken, and Coarse Rice Rate increases, and is unable to reach rice harves job requirements.
Summary of the invention
The purpose of the invention provides a kind of boomerang of new construction aiming at the above-mentioned problems of the prior art, design
Type spoon shape semicircular arc spoon side rice and kernel is general to comb de- plate tooth, reaches and pacifies when combing de- wheat or rice crop without exchanging direction
Dress, easy to use, strong applicability, the purpose that operation effectiveness is good, high-efficient, operation power consumption is small.
The purpose of the invention is achieved in that the de- plate tooth of the general comb of boomerang type spoon shape semicircular arc spoon side rice and kernel includes
Boomerang type spoon shape combs de- plate tooth, and the top end part that the boomerang type spoon shape combs de- plate tooth is integrally tapered, combs de- plate in the boomerang type spoon shape
Evagination semicircular arc spoon side, the arc radius size on the evagination semicircular arc spoon side are set on spoon edge position on the outside of the spoon body of tooth
R is 1.5-2.5 millimeters.
The invention is effectively overcome and is solved existing using tapered outer ends and the design of the structure on evagination semicircular arc spoon side
The technology for having boomerang type spoon shape that must reversely install and use when combing larger operation resistance existing for de- plate tooth, comb dehydration rice crops is asked
Topic, with structure novel, simple, reasonable, easy to install and use, strong applicability, generalization degree is high, operation quality is good, efficiency
The feature high, Brown Rice rate is low, power consumption is few.
Detailed description of the invention
Fig. 1, which is that boomerang type spoon shape semicircular arc spoon side rice and kernel is general, combs de- plate toothing schematic diagram；
Fig. 2 is A-A sectional view in Fig. 1；
Fig. 3 is the portion B enlarged drawing in Fig. 2.
Piece number illustrates in figure:
1, boomerang type spoon shape combs de- plate tooth, 2, evagination semicircular arc spoon side.
Specific embodiment
The invention embodiment is described in detail with reference to the accompanying drawing.A kind of boomerang type spoon shape semicircular arc spoon side
The de- plate tooth of the general comb of rice and kernel includes that boomerang type spoon shape combs de- plate tooth 1, and the top end part that the boomerang type spoon shape comb takes off plate tooth 1 is integrally in cone
Shape is combed in the boomerang type spoon shape and evagination semicircular arc spoon side 2, the evagination is arranged on spoon edge position on the outside of the spoon body for taking off plate tooth 1
The arc radius size R on semicircular arc spoon side 2 is 1.5-2.5 millimeters.
Operation is in use, the cone cell top end part that boomerang type spoon shape combs de- plate tooth 1 is easily inserted between rice and kernel fringe head interior, insertion
Resistance is small, and power consumption is small, and it is good to comb de- effect.Boomerang type spoon shape combs the evagination half on the outside of the spoon body of de- plate tooth 1 on spoon edge position
Arc-shaped spoon side 2 avoids the damage when comb is dehydrated rice crops to rice grain glume, to reduce rice harves operation
Coarse Rice Rate guarantees rice harves operation quality.
