Description
Technical field
The present invention relates to agricultural mechanical fields, and in particular to a kind of straw rope buries getting fat method and buries vehicle.
Background technique
The straw in harvest crops post-processing field is always the problem that people face, and is waited for if straw directly to be stayed in field
It rots not can guarantee the timely cultivation of crops of lower season then, solves according to the method for burning, first is that fire is easily caused,
Threaten the security of the lives and property of the masses；Second is that burning generation high temperature, which increases surface temperature sharply, can destroy soil texture, directly
It burns to death, the beneficial microbe in boiling hot dead soil earth, causes farmland quality decline to influence crop and soil nutrient is fully absorbed, directly
The yield and quality for influencing field-crop, influences agricultural income, so burning straw is that country prohibites.As farmyard manure
Material, straw contain the ingredients such as nitrogen, phosphorus, potassium, microelement, straw are buried go back to field with tractor, straw was by 15 to 20 days
Decomposition just will become good nutriment.Returning to the field again after the prior art usually crushes straw not only needs to consume a large amount of
The energy has also aggravated the financial burden of peasant.

Structural schematic diagram, the straw rope in the present embodiment buries getting fat method and buries vehicle, including the following steps:
(1) straw is woven into straw rope；
(2) strip groove is opened on wait the soil that applies fertilizer, straw rope prepared by step (1) is put into the strip groove；
(3) strip groove is buried and is compacted.
In the present embodiment, in step (1), straw is woven into a straw rope and is coiled, in step (2), by disk
Around straw rope be put into strip groove by way of continuous unwrapping wire.
In the present embodiment, in step (2), while opening strip groove, straw rope is depressed into the slot bottom of strip groove.
In the present embodiment, in step (2) and step (3), the straw rope of coiling by a burial vehicle realize automatically unwrapping wire,
It buries and is compacted.
In the present embodiment, including car body 1, the actinobacillus device 2 that is set to 1 front end of car body, the front-wheel 11 for being set to car body 1
Fluting band 3 and the shovel soil burial device being set to behind 11 side of front-wheel, the fluting band 3 are coated at front-wheel 11, and fluting band 3 is used for
The put straw rope of actinobacillus device is simultaneously pressed into slot bottom simultaneously by roll grooving on soil face under car body gravity, and the shovel soil is covered
It buries device and shovels strip groove side soil in strip groove and by the rear-wheel of car body and be compacted；Unwrapping wire dress is respectively set in car body
It sets 2, fluting band 3 and shovel soil buries device, unwrapping wire, fluting and shovel soil can be achieved at the same time and bury, save labour and time；Due to
Tire is typically all that rubber is made, and is not enough to roll to form deeper slot in the fields, so being arranged special fluting in front-wheel
Straw rope can be pressed into soil during traveling, and at the same time forming strip groove, eliminate the work of manpower grooving by band 3
The slot measured, while opened up can guarantee straightness, and can effectively avoid artificial grooving bring influences；Shovel soil is buried device and is located at
Front wheel side rear direction shovels the soil on strip groove both sides in slot after front-wheel is pressed into straw rope, implements to bury, and lean on rear-wheel
The soil shoveled in slot is compacted, straw rope is fixed in strip groove, whole device structure is simple, is conducive to realize, have
Effect straw rope is buried into soil, it is high-efficient.
In the present embodiment, the actinobacillus device include the first pay off rack 21 and be arranged symmetrically with the first pay off rack 21 second
Guiding device is arranged on pay off rack 22, first pay off rack 21 and the second pay off rack 22, guiding device is used for will be described
Before the put straw rope of actinobacillus device is directed to the fluting band 3 of the front-wheel 11, prevent straw rope from falling off；The fluting band 3 is arranged
There is the guide groove 33 for limiting the disengaging of straw rope；The car body further includes being fixed on the front-wheel 11 by bearing and shoveling soil to cover
It buries and rotatably compresses frame 5 between device, rotatably compress frame 5 for further compressing straw rope in strip groove, the rotation is pressed
