Abstract
The utility model relates to a harvest machine for crushing stalks and returning field directly. The utility model comprises a main shaft, knife heads, a knife roller, a machine casing, a main shaft belt wheel and a depth limiting mechanism, wherein, the main shaft belt wheel is connected with the input end of the main shaft, and the knife roller is arranged on the main shaft. A plurality of knife heads are hinged on the knife roller by helical line arrangement. The machine casing is arranged outside a machine body, and the machine casing is arranged on a tractor by a hanging girder. The operating depth is adjusted by the depth limiting mechanism which is arranged on the lower part of the machine body. The belt wheel of the tractor drives the main shaft belt wheel, the knife roller and the knife heads on the knife roller to rotate at high speed and crush crop stalks. The utility model has the advantages of simple structure, small power consumption, high stubble ploughing rate and crushing rate, strong adaptability and easy use.
Description
The utility model relates to a kind of agricultural machinery, especially direct harvest machinery with stalk crushing and returning.
Corn stalk stubble-cleaning also field work is one of mission critical in the harvest corn.The stalk crushing and returning machine of rural area use at present mainly contains two types: one is and the matching used dual spindle vertical corn stalk of tractor with small four wheels field-returning machine.This machine construction complexity, cost height not only exist toothing height, shortcoming that the chopping rate is low, also exist the problem that can not solve the chopping of lodging straw simultaneously; Another kind is horizontal hammer pawl or flail knife formula corn stalk field-returning machine.The stubble-cleaning of this field-returning machine and chopping rate are poorer, and price height, investment are big, and power consumption is big, and operation is single, and other cereal of incompatibility, wheat stubble-cleaning be the field also, can not with the supporting use of small tractor, incompatible most peasants' purchasing power.
The utility model purpose is to avoid above-mentioned weak point of the prior art and a kind of improved stalk crushing and returning machine is provided, thereby adapts to also field of various crop straw stubble-cleaning.
The purpose of this utility model is achieved by the following technical solution:
The stalk crushing and returning machine comprises main shaft 1, cutter head 2, rotor 3, casing 4, main shaft belt wheel 6, depth-limiting mechanism 7 in forming, and main shaft belt wheel 6 is connected with the input of main shaft 1, and rotor 3 links to each other with main shaft 1, and the two also can make one.Several cutter heads 2 with three blades connect the helix arrangement and are hinged on the rotor 3.Casing 4 places engine body exterior.The working depth of stalk crushing and returning machine is regulated by the depth-limiting mechanism 7 that is installed on underpart.During work, tractor belt wheel drive main shaft belt wheel 6, rotor 3 and on cutter head 2 high speed rotating and shred crop straw.
The utlity model has the advantage that the structure and the kind of drive are simple, power consumption is little and adaptability is strong, easy to use, indexs such as its stubble height, chopping rate and chopping length all are better than national standard.
Accompanying drawing 1 is assemblied in the structural representation of small tractor for the utility model embodiment;
Accompanying drawing 2 is the structural representation of the utility model embodiment main shaft and cutter head, rotor;
Accompanying drawing 3 is looked schematic diagram for the master of the utility model embodiment cutter head;
Accompanying drawing 4 is looked schematic diagram for the left side of the utility model embodiment cutter head.
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
Comprise main shaft 1, cutter head 2, rotor 3, cutter pin 11, tool rest 12, casing 4, hanging beam 5 during the utility model is formed, hang pin 13, main shaft belt wheel 6, depth-limiting mechanism 7, tensioning are spent blue 8, lifting idler pulley 9, steel wire rope 10.Main shaft belt wheel 6 is connected with the input of main shaft 1, and rotor 3 links to each other with main shaft 1, and the two also can make one.12 cutter heads 2 with three swords are evenly distributed on the rotor 3 by 3 helixes, and cutter head 2 and 12 of tool rests that are fixed on the rotor 3 are hinged by cutter pin 11.Casing 4 places engine body exterior, plays frame and protective effect, and main shaft 1 can be installed on it.Casing 4 is installed on the tractor front beam by hanging pin 13 and hanging beam 5.Depth-limiting mechanism 7 is for being contained in the gauge wheel or the slide plate of casing 4 bottoms, in order to regulate working depth.
Between tractor belt wheel and main shaft belt wheel 6, regulating wheel 14 is housed.
Be the climing chopping and returning that carries out of crop straw, vegetables stem upright to the field or unordered lay fast and efficiently, can nearside divider 15 be set at casing 4 front ends.During operation, crop straw is pushed volt earlier in facility the place ahead.
During work, by regulating wheel 14 with belt 16 tensionings, with anti-slip.Belt 16 is transferred to main shaft 1 with power by main shaft belt wheel 6, rotor 3 is made high speed rotating under it drives, cutter head 2 is after skimming over the face of land, it is super that straw is raised, simultaneously, finish cut-out to crop straw, smash with certain linear velocity, thereby reach the purpose of crushed straw, the straw after the pulverizing evenly is sprinkled upon in the working width.
Ascending, descending of the present utility model realizes by elevating mechanism, its power can be provided by the tractor oil pump that matches, elevating mechanism spends indigo plant 8, lifting idler pulley 9, steel wire rope 10 to form by tensioning, tensioning spends an end of blue 8 to link to each other with hydraulicefficiency elevation structure on the tractor, the other end is connected with steel wire rope 3, to regulate the tension force of steel wire rope.Steel wire rope 3 is connected with casing by lifting idler pulley 9, thereby realizes the transmission of lifting power.
