Description
Technical field
The utility model belongs to the farm machinery technical field, relates to a kind of wide cut straw crushing and field-returning machine, is specifically related to the two crushing chamber bilateral transmission wide cut straw crushing and field-returning machine of the single dividing plate in a kind of centre.
Background technology
The straw chopping and returning technology is that agricultural goes up one of most popular technology.It improve soil structure, increase fertility of land, the people that act as of aspect such as environmental protection generally acknowledge.Straw crushing and field-returning machine is exactly the field crops crushed stalk and sheds agricultural machinery in the field.Operation principle: the straw crushing and field-returning machine configuration is mounted on the tractor rear portion, the power take-off of tractor is passed to the straw crushing and field-returning machine speed-changing gear box through universal joint with power, pulverize cutter shaft by driving after the speedup of gear, blade on the cutter shaft is rotated at a high speed, produce very high rotating speed and kinetic energy, stalk cut-out in field is squeezed in the case, and and stationary knife together to stalk repeatedly impact, tear, effect such as rubbing is until with crushed stalk, crushing straw is on air-flow and action of centrifugal force lower edge encloser inner wall are shed in the wings ground equably.The crushing chamber that the basic structure of straw crushing and field-returning machine is made up of suspension arrangement, casing and stationary knife, pulverizing cutter shaft, transmission device and land wheel etc. constitute.
At small size wide straw crushing and field-returning machine, the general work fabric width is less than 2 meters, and the transmission and the performance ground that adopt the one-sided transmission of single crushing chamber can satisfy power are realized more.Be that the straw crushing and field-returning machine speed-changing gear box has only a side outputting power, facility one side has belt transmission, and pulverizing cutter shaft is one.But on the soil of broadness, along with the appearance of big-power tractor, grain header, just need supporting with it wide cut straw crushing and field-returning machine tool, fabric width generally surpasses 2.5 meters, even more than 4 meters.Land-reclaimable and production and construction corps is regional and along with the centralized and unified realization of cultivating pattern in soil, this wide cut straw crushing and field-returning machine tool also more and more is employed in China northeast and northwest.
The straw crushing and field-returning machine of wide cut is if adopt single crushing chamber unreasonable on the structure like this, and one-sided transmission can not be satisfied the high power transmission requirement.This project adopts two crushing chambers to smash the bilateral transmission along separate routes of stalk, power exactly, and forms two structures of pulverizing side by side by single membrane support both sides, centre cutter shaft end bearing.Can realize that the wide cut operation makes one-sided load lighter again, simultaneously again because the narrower interior middle not remaining residue stalk of entire job fabric width that makes of central dividing plate does not influence the view picture operation.
The utility model content
In order to overcome defective of the prior art, solve the problems of the technologies described above, the utility model provides a kind of wide cut straw crushing and field-returning machine, specifically is the two crushing chamber bilateral transmission wide cut straw crushing and field-returning machine of the single dividing plate in a kind of centre.
Its technical scheme is as follows:
A kind of wide cut straw crushing and field-returning machine, comprise the suspension arrangement that links with tractor, the land wheel that stubble is cut in control, also comprise by central dividing plate casing is divided into two crushing chambers arranged side by side, described two crushing chambers arranged side by side are left crushing chamber, right crushing chamber, and the pulverizing cutter shaft of central dividing plate supporting both sides constitutes reducing mechanism arranged side by side; The speed-changing gear box of two outputs is connected with removable semiaxis formula transmission device with driving shaft, and an other end of semiaxis formula transmission device is connected with the pulverizing cutter shaft.
Described driving shaft is divided into left half axle and right axle shaft by speed-changing gear box.
Operation principle: the power take-off of tractor is passed to speed-changing gear box through universal joint with power, reach two-semiaxle after the speedup by gear, the belt pulley in the semiaxis outside drives both sides through belt and pulverizes cutter shaft, blade on the cutter shaft is rotated at a high speed, produce very high rotating speed and kinetic energy, the stalk cut-out is squeezed in the case, and and stationary knife together to stalk repeatedly impact, tear, effect such as rubbing is until with crushed stalk, crushing straw is on air-flow and action of centrifugal force lower edge encloser inner wall are shed in the wings ground equably.
The beneficial effects of the utility model:
The utility model wide cut straw crushing and field-returning machine, the stalk branch is fulfiled assignment by two reducing mechanisms in the width of cloth of will working, and working width has increased more than one times, has realized that the wide cut of facility maximizes.Also constitute because this straw crushing and field-returning machine is similar to two moving facility of patrilineal line of descent with only one son in each generation, originally the moving straw crushing and field-returning machine parts of patrilineal line of descent with only one son in each generation can use substantially, have improved the versatility of parts, are conducive to save seriation, the standardization of cost and facility together.Crushing chamber is divided into two parts by central dividing plate, the both sides independently terminal bearing of cutter shaft are supported on the central dividing plate, blade on the cutter shaft of both sides is in dividing plate place close together, the position of dividing plate is to arrange by concrete cropping pattern simultaneously, do not stay the residue stalk in the middle of making in the comminution process work width of cloth, as same complete reducing mechanism in operation; The speed-changing gear box bilateral is exported transmission reducing mechanism separately respectively in addition, and power divides the two-way transmission, pulverizes cutter shaft and shortens, and is fit to the wide cut straw crushing and field-returning machine.Be easy to the facility equalising torque in the mill, operate steadily in the work; The load that reducing mechanism bears is little and even, saves material consumption, alleviates facility weight, can adapt to multiple line-spacing planting requirement, and is effective, fault rate is low.Be fit to the land-reclaimable and production and construction corps area in China northeast and northwest, cultivate the realization of pattern along with the rural holding is centralized and unified, this wide cut straw crushing and field-returning machine will more and more be used.
