Positive and negative bidirectional rotation twin shaft knife straw chopping and returning machine
Technical field
The utility model, which relates to, belongs to field of agricultural machinery, particularly a kind of positive and negative bidirectional rotation twin shaft knife straw chopping and returning machine.
Background technology
Due to containing a large amount of organic matter in stalk, consider that straw-returning is one from Circulation Agriculture Development economic angle The work pattern being of great significance, the development around stalk crasher are always one of important directions of studies in China;At present There are mainly two types of the equipments of form for the stalk crasher produced in the market:First, the stalk crasher of matching tractor, the equipment It is individually to crush returning to the field for field straw after harvesting;Second is that the stalk crasher of mating combine harvester, is developed Pulverizer more rotors moving knife mainly are installed as main working parts using one, by with combine harvester straw outlet It is connected, so as to which the stalk to the discharge of harvester straw outlet is crushed and shed.
A kind of existing stalk crasher suitable for combine harvester(Patent No. CN201520855013.7), including Upper and lower two shafts are connected by gear drive between shaft, in work, stalk first from combine harvester straw outlet discharge into Enter pulverizer, being generated impact force by cutting blade high-speed rotating on pulverizer twin shaft carries out first time crushing;Two Coordinated between a shaft by two-groove belt pulley and single slot belt pulley, directly using belt transmission connection, make driving shaft and driven The equal rotating Vortex of axis shreds so as to carry out second to stalk in indifferential;This existing stalk crasher, exist with Lower deficiency:1st, because using belt transmissioning mode, fix tightly soundness is insufficient, is used for a long time and skidding, abrasion easily occurs, such as in cutting straw Failure during stalk can then block influence discharging;2nd, using belt transmissioning mode so that two shafts of driving shaft and driven shaft are revolved in the same direction Turn, part stalk can not be caused without filling to ensureing crush efficiency through putting into practice the blade of driving shaft and driven shaft under rotating Vortex Divide to crush just to fall into below casing and accumulate, cause discharge thickness uneven, shed range and be also restricted.
Invention content
In view of the above shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a kind of letters of structure Just, the better straw chopping and returning machine of crushing effect.
The utility model design thus uses following scheme:
Positive and negative bidirectional rotation twin shaft knife straw chopping and returning machine including casing, is equipped with crushing chamber, the powder in the casing The upper end of broken chamber and the straw outlet of full-feeding combine harvester connect, and the upper and lower part of crushing chamber is separately installed with driving shaft And driven shaft, the driving shaft are staggered with driven shaft, it is uniformly distributed in an axial direction on the driving shaft to have several groups of crushing knifes Piece, the Disintegrating knife described in any one group include at least two strip blades being located on same circumference, the driven shaft upper edge It is axial it is uniformly distributed have several cutting blades, it is corresponding between any two cutting blade that there are one strip blade, the actives Axis and driven shaft are coaxially fixed with belt pulley and driving gear in stretching out outside crusher chamber in the same direction on the external part of the driving shaft, Driven gear is fixed on the external part of the driven shaft, is equipped on the casing between the driving gear and driven gear just Grade shaft and secondary shaft are coaxially fixed with the first transmission gear and the second transmission gear, the secondary in the primary shaft Third transmission gear and the 4th transmission gear are coaxially fixed in shaft, the driving gear is engaged with the first transmission gear, institute The second transmission gear is stated to engage with third transmission gear, the 4th transmission gear is engaged with driven gear, the belt pulley with The power output shaft of full-feeding combine harvester is connected by belt transmission.
The beneficial effects of the utility model are:
The connection mode of the twin shaft of existing stalk crasher belt transmission in the same direction is improved by the utility model, is used Double geared connection mode, twin shaft forms certain speed discrepancy by gear drive, and two rotating speed directions are on the contrary, make Disintegrating knife and cutting blade relative motion generate shearing force and are fully crushed stalk;The transmission knot of the utility model design The drive mechanism of the more existing stalk crasher of structure, it is more solid and reliable, it is not easy to plug;Crushing effect is more preferable simultaneously, discharging effect Fruit can promote more than 50%, and the forage discharged from straw outlet sheds range bigger, more uniformly.
Description of the drawings
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings, wherein:
Fig. 1 is the main perspective view of the utility model;
Fig. 2 is the side view of driving shaft and driven shaft in the utility model;
Fig. 3 is the right view of the utility model.
Specific embodiment
Shown positive and negative bidirectional rotation twin shaft knife straw chopping and returning machine referring to Figures 1 and 2, including casing 1, the casing Crushing chamber 2 is equipped in 1, the upper end of the crushing chamber 2 and the straw outlet of full-feeding combine harvester connect, crushing chamber 2 it is upper Portion and lower part are separately installed with driving shaft 3 and driven shaft 4, and the driving shaft 3 is staggered with driven shaft 4, and driving shaft 3, which is located at, to be leaned on One end of nearly straw outlet, it is uniformly distributed in an axial direction on the driving shaft 3 to have several groups of Disintegrating knifes, the crushing described in any one group Blade includes four strip blades 5 being located on same circumference, and the circumferentially uniformly arrangement of strip blade 5, spacing is identical, described Uniformly distributed in an axial direction on driven shaft 4 to have several circular saw blades 6, corresponding between any two circular saw blade 6 there are one strips Blade 5, operating time bar blade 5 are accurately dialled in stalk between two circular saw blades 6.
With reference to shown in Fig. 3, the driving shaft 3 and driven shaft 4 are stretched out in the same direction outside crusher chamber 2, the stretching of the driving shaft 3 Belt pulley 7 and driving gear 8 are coaxially fixed on end, driven gear 9, the master are fixed on the external part of the driven shaft 4 Primary shaft 10 and secondary shaft 11 be installed, in the primary shaft 10 on the casing 1 between moving gear 8 and driven gear 9 It is coaxial to be fixed with the first transmission gear 12 and the second transmission gear 13, coaxially it is fixed with third driving cog in the secondary shaft 10 Wheel 14 and the 4th transmission gear 15, the driving gear 8 are engaged with the first transmission gear 12, second transmission gear 13 and the Three transmission gears 14 engage, and the 4th transmission gear 15 is engaged with driven gear 9, and the belt pulley 7 is combined with full feed type The power output shaft 16 of harvester is connected by belt transmission.
