When the amount of straws in the gap is small, the tensioning spring 5044 of the tensioning device 504 extends to drive the driving filament kneading roller 503 to rotate clockwise around 5041, the gap between the filament kneading rollers is correspondingly reduced, when the amount of straws in the gap is large, the tensioning spring 5044 of the tensioning device 504 is compressed to drive the driving filament kneading roller 503 to rotate anticlockwise around 5041, the gap between the filament kneading rollers is correspondingly increased, and the blockage is prevented while the kneading pressure is ensured. The straw which is further kneaded and refined is flocculent at the moment, and enters the spiral compression device 6 after falling from the gap between the kneading rollers.
Helical compression device is under chain sprocket drive's drive, and opposite direction rotary motion is to adjacent helical compression axle, refines the flocculent straw of silk that device 5 falls down by rubbing the silk, falls into the compression chamber of below, along with constantly diminishing of compression chamber cross-sectional area, flocculent straw of silk is compressed under helical blade's promotion, and density is showing and is increasing, along with helical blade's constantly rotation, the straw stream of compressed is propelling movement to discharging pipe 605, is buried soil preparation device 7 deeply by the dark pine at propelling movement to rear afterwards.
The subsoiling and deep burying device 7 moves forwards under the forward power of a tractor, and the subsoiling shovel 701 performs subsoiling on the bottom layer of the soil plough. Behind the double-wing subsoiler 701, a certain gap appears in the soil, the outlet of the discharge pipe 605 of the screw compression device 6 is right opposite to the rear of the subsoiler 701, the compressed straw flow pushed out by the discharge pipe 605 enters the gap behind the subsoiler 701 and is deeply buried by the fallen-back soil, and the land surface is leveled by the land roller 703 at the rear.
The utility model provides a still field machine of spiral compression densification straw to straw is still field machine as the basis, through broken, rub silk, compression, the densification flow, the straw section that cuts up straw still field machine is further rubbed and is handled, make its more finely divided smash, then rub silk spiral compression through smashing, the silk wadding form straw logistics density that makes the fine crushing increases, and bury the plough layer with the straw simultaneously at the in-process of rear subsoiler subsoiling, return the field with burying deeply of realization straw, promote the corruption of straw. The hard stem nodes on the surface of the corn straws are damaged by crushing and kneading the straws, so that the straws are in a soft straw filament shape, and the quick decomposition of the straws is facilitated. The straw is crushed and rolled and then is subjected to reasonable densification treatment, so that the diversity of microorganisms is obviously influenced, and the decomposition speed and the nutrient release are faster. The straw can be returned to the field in full quantity on site, soil organic matters are increased to protect the soil fertility, and sustainable development of agriculture is realized.
While the embodiments of the invention have been described above, it is not intended to be limited to the details shown, or described, but rather to cover all modifications, which would come within the scope of the appended claims, and all changes which come within the meaning and range of equivalency of the art are therefore intended to be embraced therein.
