The annular rolling cutter
The utility model relates to a kind of cutter of hay cutter.
It is a lot of to be used to cut up with a hay cutter the hay cutter kind of cutting stalk and axis piece, its cutter is had nothing in common with each other, straight plate cutter, garden arc cutter, circular knife or the like are generally arranged, but the type of these kinds all exists such shortcoming: the operation power attenuation is big, the manufacturing process complexity, because of the restriction of frame for movement layout, axially the feed quantity of feeding manner is on the low side in addition, and production efficiency is difficult to improve.
The purpose of this utility model is that a kind of annular rolling cutter will be provided, and it can overcome above-mentioned shortcoming effectively, improves axial feed quantity greatly, improves hand hay cutter and cuts efficient.
The purpose of this utility model is achieved in that a hollow Cylinder is installed in spout, utilizes the fixed cutting tool of inner edges as hay cutter; The inside of hay cutter, be provided with the garden dish that drives rotation by turning cylinder with the fixed cutting tool opposite face, diameter is slightly less than hollow Cylinder internal diameter, utilize radial ball bearing that the cutting knife of two Cylinder shapes is installed on the card of garden, be called annular rolling cutter, the cutting knife blade is its edge near hollow Cylinder.Working condition is such: high quick-action is coiled in turning cylinder drive garden to be changeed, rolling cutter moves along the fixed cutting tool edge, when material feeds, rolling cutter is done as high speed rotating by the material tangential resistance, thereby finish material slippage shear history, the forage of chopping is thrown into housing and finishes rubbing, pulverizing process with hammer leaf and tooth plate.
Compare annular rolling cutter with aforementioned various cutters and have many advantages: stationary knife and moving knife have self-excitation sharpening effect in the work, keep good slip cutting angle and material is clamped down on cutting, cutter does not need sharpening, and always is in best shearing inclination, not limited by the speed of mainshaft, it is brisk laborsaving to cut up with a hay cutter careless operation, the work efficiency height, cutting knife can be adorned 2-6 respectively by job requirement on a garden dish, adapt to the different needs of producing, be applicable to the unit of different model, low cost of manufacture, technology are simple.
Accompanying drawing 1 is that Fig. 2 is a schematic side view according to the front view of the annular rolling cutter that the utility model proposes.
(1) is hollow Cylinder among the figure; (2) be Cylinder annular rolling cutter; (3) be hammer leaf; (4) garden, back dish; (5) coil in preceding garden; (6) bear box; (7) be fixed cutting tool; (8) feeding hopper; (9) be main shaft.
Embodiment: static structure is as follows: hollow Cylinder (1) internal diameter 300mm, external diameter 320mm, high 30mm; Annular cutting knife (2) diameter 100mm, high 50mm is the garden column, garden dish (5) diameter 240mm, high 30mm, outward appearance also is the garden column, after the assembling, annular cutting knife (2) distance hollow Cylinder (1) edge 1mm; Two annular cutting knifes (2) circumference solstics is at a distance of 330mm; The rotating shaft of annular rolling cutter (2) is parallel with main shaft (9).
Dynamic structure: main shaft rotates, drive garden dish (5) high speed rotating, axially feed forage after, annular cutting knife (2) is rotated by tangential resistance, interacts chopping forage with fixed cutting tool.
