Straw chopping and returning of the invention, mulch recycling combine working principle are as follows:
1. straw chopping and returning working principle: when operation, tractor-drawn suspension mechanism moves ahead, front support roller 2 and rear branch
Mulch is compacted by support roller 5, and rear output shaft drives 4 high speed rotation crushing straw of straw stalk pulverizing knife；Smashed stalk is thrown into stalk
It conveys in screw feeder 6, it is left and right bidirectional screw that stalk, which conveys screw feeder 6, conveys stalk to centre through dynamic rotation；Crushing straw is fallen into
After stalk throw transport device 7 in and backward on put conveying, after stalk horizontal transferring device 15, stalk throwing guide plate 13 shed and also
Field, for prevent stalk continue it is horizontal after cast and set stalk and throw baffle 14, assist stalk to throw field via rear throwing guide plate.
2. mulch recovery operation principle: when work, mulch is provoked and along being delivered up clockwise by mulch pick-up unit 10,
In transmission process, the impurity such as stalk, soil and boll hull on film surface are fallen under gravity is important again, are fallen into preposition clear miscellaneous roller 8；
Preposition clear miscellaneous roller 8 roll counter-clockwise under the traction of complete machine, the impurity that will fall off are scooped into roller, as shown in figure 3, preposition clear
Clear miscellaneous spiral-poker 9 is installed, clear miscellaneous spiral-poker 9 of the impurity through rotating is delivered to field, completes clear general labourer and makees in miscellaneous roller 8.
Mulch is delivered up to end, is fallen into mulch collection device under the effect of gravity, and mulch recovery operation is completed.
3. preposition clear miscellaneous roller frame and principle: as shown in Fig. 2, preposition clear miscellaneous roller 8 by roller fixed plate 81, clear miscellaneous scoop
The compositions such as spoon 82, clear miscellaneous roller outer ring 83 and clear miscellaneous roller inner ring 84.6~8 (or grade) clear miscellaneous balers 82 are evenly arranged group
At preposition clear miscellaneous roller 8, the miscellaneous space of leakage that the clear miscellaneous baler 82 being evenly arranged is formed is divided into segment by clear miscellaneous roller outer ring 83, and
Play fixed reinforcement to entire preposition clear miscellaneous roller 8.Arrange that clear miscellaneous roller inner ring 84 plays a supportive role in roller.Operation
When, when mulch pick-up unit 10 picks up conveying mulch, the impurity such as stalk, soil on film surface are fallen from the space that clear miscellaneous baler is formed
Enter, the impurity fallen into is scooped into roller by the preposition clear miscellaneous roller 8 of rotation, and the clear miscellaneous spiral-poker 9 arranged in roller is by impurity
It is delivered to combine two sides.
Finally it is noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations.To the greatest extent
