Abstract
The utility model discloses hay cutter knife section, the grinding first of knife section (1) forms cutting edge (2) for the acute angle, and the blade tip of cutting edge (2) (2') are straight line or optimalarc, and characterized by evenly distributed on cutting edge (2) has seted up sword groove (3), the front end formation blade tip of sword groove (3) (3'). The blade tip of cutting edge when it cuts off the straw (2) (2') incompletely cut off earlier the straw, and the remainder is cut off by the blade tip in sword groove (3) (3'), produce the extrusion effect of tearing to shreds to the straw, make the broken festival of the little paragraph of straw, improve searching for food of livestock.
Description
Technical field
The utility model relates to the knife section of farm machinery hay cutter, particularly hay cutter.
Background technology
Small farm hay cutter tool for tangerine bar has multiple product, as air charging type hay cutter, and multi-functional hay breaking machine, chaff cutting breaking rolling machine etc.Although existing various hay breaking machine is textural each different at concrete structure, it has one to rotate movable knife rack, rotation movable knife rack is installed with moving knife blade and coordinates with the hard-wired ledger-plate in feeding mouth place on body, carries out hand hay cutter break to tangerine bar.Multi-functional hand hay cutter grass meal is broken, chaff cutting breaking rolling machine is provided with pulverizing and rubbing device is smashed pulverizing again to cutting up with a hay cutter the tangerine bar of having no progeny, rubbed.
The blade part of the knife section of above-mentioned prior art hay cutter is straight line or arc line shaped, the grinding first of blade is that acute angle forms blade, its ledger-plate coordinates the tangerine bar by charging aperture conveying is come in neatly to cut off, tangerine bar after cut-out is pole shape segment joint, due to the not broken joint of pole shape segment joint, the crust surface of straw is smooth and cortex is harder, livestock is not often liked to search for food, affect livestock edible very much, and the nutrient component of straw central part fully can not be searched for food by livestock with the feed be attached on straw surface after puddling with concentrated feed, cause the waste of straw and concentrated feed.For reaching, with regard to needs, fragmentation work being carried out to the broken joint of section joint, namely using the reducing mechanism of hay breaking machine that the joint in pole shape segment after cut-out is carried out fragmentation.Use equipment cost must be increased like this.
Utility model content
It is simple that the purpose of this utility model is to provide a kind of structure, manufacture method, can the hay cutter knife section of effective broken tangerine bar.
The utility model hay cutter knife section, the grinding first of knife section 1 is that acute angle forms blade 2, and the blade tip 2 ' of blade 2 is straight line or arc line shaped, it is characterized in that being uniformly distributed on blade 2 offering sword groove 3, and the front end of sword groove 3 forms blade tip 3 '.
The utility model offers sword groove 3 owing to being uniformly distributed on blade 2.Its coordinate with stationary knife straw is cut off time blade 2 blade tip 2 ' first incomplete cut-off is carried out to straw, remainder is cut off by the blade tip 3 ' of sword groove 3, because knife section 1 is high-speed rotation, in this cut-out work, sword groove 3 pairs of straws produce extruding and tear up effect, the straw of cut-out is produced and tears fragmentation, straw segment is made to save broken joint, broken pulverize cracker thin of not resembling is torn although this, but be enough to destruction to straw and do not become pole shape segment joint, the smooth hard crust of straw is torn fragmentation, improves searching for food of livestock.
The utility model structure is simple, and manufacture method, can be used for various agricultural hay cutter, as air charging type hay cutter, and multi-functional hay breaking machine, chaff cutting breaking rolling machine etc.
