Description
Technical field
The utility model relates to a kind of corn picker, and particularly a kind of bract also field corn picker, belongs to technical field of agricultural machinery.
Background technology
At present, corn picker comprises the functions such as stem cutting, harvesting, peeling, threshing, stalk process, during harvesting, harvesting is carried out under corn growth state, be pulled off by fruit ear handle, fruit ear is entered in apparatus for peeling off and is divested by bracteal leaf of corn, the bracteal leaf of corn peeled directly is discharged and is fallen into farmland.Due to comparatively large without the bract volume pulverized, decompose comparatively slow, be difficult to as fertilizer also field, and easily block the sowing opening of sower, affect peasant and cultivate.
In order to improve this problem, bract shredding mechanism installed by some grain header, although play certain bract chopping effect, but still there is many deficiencies, on the one hand, only under cutter shaft rotary action, drive bract to discharge forward, being short of power of its bract conveying, be easy to produce and block, and moving knife is a large covering of the fan, during High Rotation Speed, the powerful resistance that this covering of the fan will become bract and passes through, be also easy to the obstruction causing bract, treating capacity is little; On the other hand, the bract after chopping directly discharges also field, because the bract of chopping is strip, after direct returning to farmland, bring adverse effect still can to the farming of peasant, process thorough not, and owing to limitting in the space of car body, be difficult to increase extra breaking plant more broken further to bract.
Utility model content
According to above the deficiencies in the prior art, technical problem to be solved in the utility model is: provide a kind of bract also field corn picker, can shred and pulverization process bract, and process fully and completely, really realizes bract also field.
Bract described in the utility model is field corn picker also, comprise vehicle frame and be arranged on bract shredding mechanism, the straw millstone on vehicle frame, bract shredding mechanism is arranged on above straw millstone, drainage conduit is connected bottom bract shredding mechanism, the discharge gate of drainage conduit is arranged in the gap between straw millstone and front side vehicle frame, and corresponding with the blanking port of straw millstone.
Bract shredding mechanism is arranged on above straw millstone, and drainage conduit is set between, the bract of chopping is discharged through drainage conduit, along with the advance of car body, the bract of chopping enters in straw millstone by blanking port, the bract of chopping is pulverized by straw millstone further, goes back field again after realizing the thorough pulverization process of bract completely.
The trajectory of described drainage conduit is curve, and the curvature of its maximum bending section is less than 3.5m
-1.
Described drainage conduit is rectangular tube or round tube, and the length of side of drainage conduit or diameter are 150mm ~ 300mm.
Described bract shredding mechanism comprises material feeding box, crush box and feed box, drainage conduit is connected with feed box, conveying chopping assembly is provided with in crush box, stationary knife assembly, conveying chopping assembly comprises main output shaft, feeding screw, first flight, second flight, moving knife and material toggling assembly, main output shaft is along walking to expect that direction is divided into feeding section successively, chopping section and material toggling section, feeding screw is arranged in feeding section, first flight, second flight symmetry is arranged on chopping section both sides, moving knife is arranged in the first flight, between second flight, material toggling assembly is arranged in material toggling section.By the helical-blade of feeding screw, the bract fallen in crush box is pushed ahead, conveying for bract provides power endlessly, at the shredding stage of bract, along with the High Rotation Speed of main output shaft, stationary knife and moving knife position are formed shreds plane accordingly, while bract is shredded, form certain advance resistance, now, by the helical feed effect of the first flight and the second flight, half pulverizing or full bract of pulverizing are exported along helical duct, two groups of flights realize the maximum using of the confined space, thus largely avoided the choking phenomenon of bract, promote handling capacity.
Described moving knife is shaft-like cutter.
Described moving knife is formed by the high strength bar be laterally installed on main output shaft, and the length that high strength bar two ends exceed main output shaft surface is equal.
Described moving knife comprises the bar cutter set gradually, No. two bar cuttves and No. three bar cuttves.
Described material toggling assembly is made up of the arc switch-plate being arranged on main output shaft material toggling section, and switch-plate is provided with reinforcement.
Described stationary knife assembly comprises and being made up of arrange along crush box even circumferential 2 ~ 4 cuttves that are ranked, and stationary knife is arranged on stationary knife seat, and its shape is triangle.
Compared with prior art, the beneficial effect that the utility model has is:
This bract also field corn picker passes through to increase bract shredding mechanism, drainage conduit, utilize vehicle body space to greatest extent, bract, after chopping, enters in existing straw millstone and pulverizes further, realize the thorough pulverization process of bract, reach the object in completely also field; Track due to drainage conduit is curve, must solving the problem that it easily blocks, by rationally arranging the radius of curvature of drainage conduit, making the curvature of maximum bending section be less than 3.5m
-1, thus promote bract disposal ability; Bract shredding mechanism is by arranging feeding screw, and to the bract constantly feeding forward falling into crush box, the conveying for bract provides power endlessly, promotes bract and travels forward, and avoids occurring to be detained blocking; Shredding stage is cut bract, due to the High Rotation Speed of moving knife, the shearing of moving knife and stationary knife, to rub, while bract is pulverized, certain obstruction power is formed to the conveying of bract, now, by the conveying of the first spiral and the second spiral, half pulverizing or full bract of pulverizing are exported along helical duct, and two groups of flights realize the maximum using of the confined space, thus largely avoided the choking phenomenon of bract, promote handling capacity; Because moving knife adopts high strength bar to make but not existing covering of the fan structure, substantially reduce the blocking surface that moving knife High Rotation Speed is formed, bract is passed through smoothly.
