Description
Technical field
The utility model belongs to a kind of removable cutting tool and dust-proof stalk crasher.
Background technology
As shown in figure 1, straw chopping and returning machine is (referred to as：Stalk crasher) it is upright to field or lay corn, height
Beam, cotton, rice and wheat stalk carry out mechanization returning to the field operation on the spot, can effectively solve south " double rush for harvesting and sowing ", northern " three summer jobs ", " three
During autumn " the problem of labour's anxiety, the contradiction that misses the farming season.The smog due to crop straw burning can be avoided to cause vehicle can not be just
Normal traveling, aircraft can not normally take off landing and severe contamination environment, destroy soil the destruction such as organic matter it is ecological the problem of.Straw
Stalk chopping and returning, not only for the increase soil organism, improvement soil texture, increasing fertility of land has obvious effect, and is gone back
The soil is porous for soil behind field, and retain water and nutrients ability is strong.
Straw chopping and returning machine is the supporting rearmounted work tool of large and middle tractor, is dragged by the trifilar suspension frame of tractor

Contacted with ground.Main driving wheel and belt pulley outer cover protective cover 8.Toolbox on knife cylinder wall rotates at a high speed, in feeding
Mouthful place generation negative pressure, under the booster action of negative pressure, stalk is inhaled into frame, and with the first row bed plate in frame meet by
To once cutting, then flowing through in inswept frame due to the change in section, causing the change of air velocity, make stalk multiple
Cut and hammer by toolbox.When stalk enters the gap of toolbox and bed plate, repeatedly sheared, rubbing and torn
Draw and make it that stalk is further crushed.Finally pulverized stalk is uniformly shed in the presence of air-flow and centrifugal force, is completed
Returning to the field operation on the spot.
The structure of the drum shaft axis part of traditional straw chopping and returning machine is divided into two kinds：One kind is built-in bearing type, should
Without dust guard, the bearing chamber in operation is easily accessible dust and causes lubrication failure to make bearing damage structure；Another is external axle
Hold type bearing chamber oil sealing located at frame side plate outside, herein rotate needed for preset clearance it is larger, at the structure oil sealing easy oil leakage and
Dust-proof effect is bad.
While traditional straw chopping and returning machine is easily caused, momentary load is excessive to cause main frame driveline damage and the machine
Driving member unbalance stress overload is damaged.Therefore, traditional straw chopping and returning machine spoilage is high, causes utilization rate low, uses
Short life.On the other hand, the toolbox of traditional straw chopping and returning machine, not easy-maintaining and replacing, is easily caused in not same district
Domain stalk crushing effect can not meet the agronomy demand of locality, significantly reduce and use scope, reduce the utilization rate of machinery.
The content of the invention
