Abstract
The invention discloses an arc-shaped threshing cutter of a threshing machine; the arc-shaped threshing cutter consists of a cutter head, a cutter body, a cutter handle and a hard alloy sprayed and coated on a cutting edge. The cutting edge surface of the cutter body is designed in an arc shape. The arc-shaped threshing cutter of a threshing machine has the following beneficial effects that: the strength of the threshing cutter is increased, the arc-shaped cutter face to tobacco leaves has a large tearing force, and the improvement of the leaf-stem separation efficiency, the improvement of big-leaf intermediate-piece rate and the improvement of the product quality are achieved; the leaf content in the stems is reduced, the consumption of the tobacco leaves is reduced and the product yielding is improved.
Description
Technical field
The invention belongs to the separatory technical field of structures of forging a knife of threshing and redrying production line middle period stalk.
Background technology
At present, widely used forging a knife in threshing and redrying production line.It by cutter head, blade, handle of a knife, be sprayed on the thin slice cuboid that the carbide alloy on the edge of a knife is formed.Its knife face shape adopts rectilinear form always, and whole blade is a rectangle, and this index of peeling off tobacco leaf aborning of forging a knife is: big-and-middle blade rate 87% more than the 12.7mm; 6.35mm with blade rate 96%, the following fragment rate 0.5% of 3.18mm is because its simple shape; Yielding, cause the oil pressure cigarette; Must make regular check on cleaning and forge a knife, maintenance is frequent, is difficult to the index of improving the quality of products.
Summary of the invention
In order to overcome the existing said defective and the deficiency of forging a knife and existing; The present invention provides a kind of arc to forge a knife, and knife face is set to arc by straight line, and the intensity of forging a knife is increased; Forge a knife inertia force increase, cutter and the increase of tobacco leaf contact-making surface, contact-making surface by the line height, and it is big to the power of tearing of tobacco leaf to forge a knife.
The technical solution adopted for the present invention to solve the technical problems is:
The blade face of blade is set to arcuate shape, and its arc is circular arc or hyperbola or parabola shaped.
Original version of forging a knife realizes through changing in the present invention; Form by arc cutter head, arc blade, handle of a knife and the carbide alloy that is sprayed on the edge of a knife; Forging a knife is installed in cylindrical beating on the roller with attachment bolt and cutter pin, and with playing the roller rotation, arc cutter head, arc blade and the carbide alloy that is sprayed on the edge of a knife contact with tobacco leaf; Tobacco leaf is peeled off from offal, and its superiority is following:
1, the arc knife face of forging a knife is beaten leaf length and has been increased by 15% than original straight line cutter length, thereby increases its dozen leaf ability.
2, because cuboid straight line knife-edge changes arc into and forges a knife, and the escapement ratio when tobacco leaf is stripped from when beating leaf will effectively reduce, and blade can better be peeled off from offal, effectively improve the tobacco leaf rate of recovery, reduce the tobacco leaf loss.
3, arc forge a knife the contact smoked sheet be one progressively process (seeing) from microcosmic thus arc forge a knife tearing of smoked sheet torn open comparatively mild, so make the fragment rate of smoked sheet obtain certain reduction, thereby improved leaf quality preferably.
The invention has the beneficial effects as follows that the intensity of forging a knife increases, curved knife is big in the face of the power of tearing of tobacco leaf, improves leaf stalk separative efficiency, improves big-and-middle rate of leaf, improves product quality; Reduce stalk and contain the leaf rate, reduce the tobacco leaf loss, promote the product yield.
Below in conjunction with accompanying drawing and case study on implementation the present invention is further specified.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure 1, cutter head, 2, blade, 3, handle of a knife, 4, be sprayed on the carbide alloy on the edge of a knife.
The specific embodiment
A kind of threshing machine arc is forged a knife, and the blade face of the present invention's blade is set to arcuate shape, and its arc is circular arc or hyperbola or parabola shaped.
In Fig. 1, carry out the arc of architecture advances and forge a knife, by arc cutter head, arc cutter hub, handle of a knife and be sprayed on the matter alloy composition of the edge of a knife on hard.Adopt novel arc to forge a knife, arc cutter head, arc cutter hub tear, cut tobacco leaf in the production, and the index of peeling off tobacco leaf is: big-and-middle blade rate 89% more than the 12.7mm, and 6.35mm is with blade rate 98.0%, and the following fragment rate 0.3% of 3.18mm has improved product quality.
Claims (4)
1. a threshing machine arc is forged a knife, and is made up of cutter head, blade, handle of a knife, the carbide alloy that is sprayed on the edge of a knife, it is characterized in that the blade face of blade is set to arcuate shape.
