Specific implementation mode
The following describes the utility model in further detail with reference to the accompanying drawings, to enable those skilled in the art with reference to explanation
Book word can be implemented according to this.
As shown in Figs 1-4, the utility model provides a kind of hob-type straw chopping cylinder, including：Closed roller
100, it is hollow cylindrical tube closed at both ends, the barrel of the cylinder and end face all have certain thickness.The envelope
The both ends of enclosed roller 100 are fixedly and coaxially connected hobboing cutter axis 130；Closed roller 100 is divided into multiple construction sections in an axial direction.At this
In embodiment, closed roller 100 is cast iron quality, and barrel lenght is 800~900mm, and outer diameter is 600~800mm, the peace
It is two to fill section, respectively the first construction section 110 and the second construction section 120, the first construction section 110 and the second construction section 120 length
It spends equal, and there is fraction to partly overlap region among the first construction section 110 and the second construction section 120.Using closed roller,
Stalk in the course of work can be prevented to be involved in inside shredding mechanism, shredding mechanism is caused to block, cleaning is difficult.Shredding mechanism blocks
The abrasion of shredder bar can be also aggravated, it is therefore prevented that shredding mechanism blocks the service life that can also extend shredder bar.
Multiple hob heads 200 comprising footing 210 and the mounting surface 220 being at certain angle of inclination with footing, footing 210
It is an integral structure with mounting surface 220, footing 210 is fixedly connected on using welding manner on the outer wall of closed roller 100.Peace
Angle between dress face 220 and the excircle tangential direction of the closed roller 100 is 20 °~30 °.
Multiple shredder bars 300, are the flat plate blade of parallelogram, and the shredder bar 300 is detachably arranged in institute
It states on hob head 200, the lower surface of shredder bar 300 is resisted against on the mounting surface 220.Preferably, the shredder bar 300 has
There is double-sided blade, is located on 300 longer one groups of opposite side of the shredder bar, and the double-sided blade is respectively positioned on shredder bar 300
Upper surface.Two blade surfaces 310 are different according to the direction of installation, respectively as chopping sword and spare sword, used in chopping cylinder
Cheng Zhong only shreds sword and plays the role of cutting stalk, and use can be exchanged by shredding sword and spare sword, to increase the use of blade
Service life, while the time of processing blades again is saved, improve working efficiency.
The size of mounting surface 220 is less than the size of 300 lower surface of shredder bar, width and 300 table of shredder bar of mounting surface 220
It is of substantially equal that face width removes two 310 width of blade face.300 middle part of the shredder bar is uniformly arranged multiple along edge line direction
Through-hole 330,220 middle part of mounting surface are equipped with and 320 one-to-one internal thread of the through-hole along the direction of vertical mounting surface 200
Shredder bar 300 is connected on the mounting surface 220 by hole using bolt 330.After installation is complete, the twolip face of shredder bar 300 is just
It is located at except the region of the shredder bar upper surface corresponding to mounting surface 220 well.The mounting surface 220 of the hob head and the closing
The angle that the excircle tangent line of formula roller 100 is formed is 20 °~30 °, makes 300 surface of shredder bar and the closed roller 100
Excircle tangent line formed angle δ be 20 °~30 °.When the lower surface of shredder bar 300 is resisted against on the mounting surface 220,
The angle that the excircle tangent line of mounting surface 220 and the closed roller 100 is formed and 300 surface of shredder bar with it is described closed
The angle δ that the excircle tangent line of roller 100 is formed is equal；It can also be installed between the lower surface and mounting surface 220 of shredder bar 300
Gasket, the angle formed to the excircle tangent line of shredder bar 300 and the closed roller 100 is finely adjusted, to reach best
Chopping result.
300 interlaced arranged for interval of shredder bar on first construction section 110 and the second construction section 120, and two groups of choppings
The angle formed between the edge line of knife 300 and closed cylinder axis is complementary relationship.That is the blade on the first construction section 110
Angle between line and closed cylinder axis is α1, α1It is 5 °~10 °；Edge line on second construction section 120 and closed rolling
Angle between cylinder axis is α2, and meet α1+α2=180 °.One group of the shredder bar 300 compared with short opposite sides with it is described closed
The end face of roller 100 is parallel.Using arrangement in a certain angle between edge line and cylinder axis, the straw of chopping can be made
Stalk is easier to slide from chopping cylinder, avoids shredder bar parallel with cylinder axis and stalk is made to be easy to be clipped in circumferentially side
Defect between two adjacent shredder bars；It is unlikely to cause blade load uneven because angle of inclination is much again simultaneously.
The basis material of shredder bar blade is 65Mn, and surface is the iron-based material coating of Fe55 at sword, and sword area hardness is
HRC50~60, shredder bar blade sharpening angle beta be 20 °~30 °, blade have enough rigidity, wearability is good, service life compared with
It is long.
In conclusion hob-type straw chopping cylinder provided by the utility model, interlocks equipped with closed roller and inclination
Spaced apart shredder bar can overcome the shredding mechanism of existing stalk harvester to hold susceptible to plugging defect；Shredder bar is two-sided
Sword structure, the exchange that work blade surface may be implemented use, and increase the service life of blade, while saving processing blades again
Time improves working efficiency；Shredder bar cutlery has enough rigidity, and wearability is good, and service life is longer.
It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above
Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art,
Other modifications may be easily implemented, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
It is not limited to specific details and legend shown and described herein with novel.
