Description
Technical field
The invention belongs to agricultural crop straw processing machinery, and in particular to be used for bud green agricultural crop straw and rattan to one kind
The cylinder-type cutterhead of climing crushing.
Background technology
Agricultural crop straw is shredded and the mechanical pretreatments such as straw are torn brokenly, the gas production of its anaerobic digestion can be improved
And methane content, it is a kind of effective means of the utilization rate and factor of created gase for improving stalk, utilized as current stalk marsh gas and ground
The important content studied carefully.Hay cutter is one of the device crushed to agricultural crop straw, and chopper is the core of hay cutter work
There is following defect in one of part, the chopper of existing hob type chaff cutter：The 1st, blade angle is installed unreasonable so that dynamic cutting knife
18 °~20 ° slip cutting angles cannot be obtained with cutter, and then influences the operating efficiency of hay cutter；2nd, due to the installation of moving knife support
On the same axis, the same time contacting material of cutting knife cutting edge is moved so as to the cutting force suffered by dynamic cutting knife is larger, to blade
Infringement is serious.3rd, the blade of chopper is the blade of same form, and the crops material to the climing class of sinomenium acutum carries out shredding efficiency
It is not high.The applicant of the patentee declared a patent of patent 200820190581.X on the 1st in September in 2008 can be to rice
Wheat Straw crush but the effect of the bud green plant chopping higher for moisture content is difficult to reach expection.
The content of the invention
To solve the above problems, by change moving knife rack form and its mounting means come more it is convenient obtain 18 °~
20 ° of slip cutting angles, while static and dynamic equilibrium when maintaining chopper to operate, it is proposed that following technical scheme：
A kind of cylinder-type cutterhead crushed for bud green agricultural crop straw and tendril, including slitter shaft, moving knife support, the
One dynamic cutting knife and the second dynamic cutting knife；It is one group that even number root moving knife support and two are fixedly installed on the slitter shaft, and one group is moved
The top of knife support is provided with the first dynamic cutting knife or the second dynamic cutting knife, two moving knife support asymmetric installations in every group, mutually
Between form 10 °~20 ° and cause that the first dynamic cutting knife or the second dynamic cutting knife obtain 18 °~20 ° slip cutting angles, prevent the first dynamic cutting knife or
Second dynamic cutting knife stress is excessive and cutting edge sustains damage.
Further, moving knife backing plate is provided between the moving knife support and the first dynamic cutting knife, and moving knife backing plate is fixed and set
Put on the top of moving knife support；First dynamic cutting knife is detachably connected with moving knife backing plate.
Further, moving knife backing plate is provided between the moving knife support and the second dynamic cutting knife, and moving knife backing plate is fixed and set
Put on the top of moving knife support；Second dynamic cutting knife is detachably connected with moving knife backing plate.
Further, triangular blade is installed, triangular blade is arranged on the second dynamic cutting knife on the described second dynamic cutting knife
At cutting edge, triangular blade has 10~16 groups, every group at a distance of 30~50mm, thickness is 3~5mm.
Further, the cutting edge angle of the described first dynamic cutting knife is 30 °.
Further, according to chopper diameter computing formula in Machine DesignTo meet design requirement,
Obtain 200~300mm of chopper diameter.
Further, totally 6, the moving knife support.
Beneficial effect：
1. the present invention has can be crushed to below 30mm to bud green agricultural crop straw, and to the crops chopping of the climing class of sinomenium acutum
With laterally and longitudinally shredding, with reach preferable chopping effect and its by high speed rotating band come wind-force, after chopping
Material to exclude body 1m~2m remote, serve the effect of fan.
2. the present invention more easily obtains 18 °~20 ° sliding cuttings by changing moving knife rack form with its mounting means
Angle, while so that and static and dynamic equilibrium when maintaining chopper to operate, the softer material for the climing class of sinomenium acutum uses two kinds of differences
The dynamic cutting knife of form is cut.
