Abstract

The utility model discloses a high-speed dual-shaft stubble cleaner. The stubble cleaner comprises a machine frame, a suspension device, a speed reduction box, stubble-cleaning shafts and stubble-cleaning cutters. The suspension device and the speed reduction box are respectively fixed on the machine frame, the front and rear parts of the two stubble-cleaning shafts are supported by bearing seats, the two stubble-cleaning shafts are arranged under the machine frame side by side, a plurality of stubble-cleaning cutters are arranged on the stubble-cleaning shafts in a radial manner, the rotating semi-diameter of the front stubble-cleaning cutter is smaller than that of the rear stubble-cleaning cutter, and the rotating speed of the front stubble-cleaning shaft is larger than that of the rear stubble-cleaning shaft. The high-speed dual-shaft stubble cleaner adopts the scheme that the two stubble-cleaning shafts are arranged side by side back and forth, and two (front and rear) rows of stubble-cleaning cutters work at the same time. As the rotating semi-diameter of the two rows of stubble-cleaning cutters is different, the front row of stubble-cleaning cutters can clean crops on the stubble row face, and the rear row of stubble-cleaning cutters can clean root stubbles of the crops under the rows; twice stubble cleaning leads thorough stubble cleaning, increases the stubble cleaning depth, and improves the entire filed quality. Cutter discs can be arranged on the front stubble-cleaning shaft, and the stubble-cleaning cutters are flexibly arranged on the cutter discs, so as to lead stubble cleaning and crushing to be finished in one time, reduce damage to the stubble-cleaning shafts, and further improve the entire field quality.

Description

High speed twin shaft stubble cleaner

Technical field

The utility model relates to a kind of agricultural machinery, is specifically related to a kind of crops stubble-cleaning machinery.

Background technology

At present, farm machinery is various in style, is mostly the combined working soil form, and stubble-cleaning and rotary tillage are carried out synchronously, makes crops root stubble chopping and returning increase fertile soil.These combined soil preparing machines can only be the single shaft stubble-cleanings, implement stubble-cleaning from crop root, and are undesirable to the crops crushing effect, whole ground of influence quality.

Summary of the invention

The purpose of this utility model is to provide a kind of high speed twin shaft stubble cleaner, can implement stubble-cleaning twice to crops, and stubble-cleaning is effective, improves whole ground quality.

For achieving the above object, a kind of high speed twin shaft of the utility model stubble cleaner, comprise frame, suspension arrangement, reduction box, paring shaft and stubble-cleaning cutter, suspension arrangement and reduction box are separately fixed on the frame, two paring shafts are set up in parallel below frame by before and after the bearing block support, radially be provided with several stubble-cleaning cuttves on the paring shaft, preceding stubble-cleaning cutter radius of turn is less than back stubble-cleaning cutter radius of turn, and preceding paring shaft rotating speed is greater than back paring shaft rotating speed.

Be disposed radially several cutterheads on the paring shaft before described, evenly movable on each cutterhead at least three stubble-cleaning cuttves be set, the setting that interlaces each other of the stubble-cleaning cutter on the adjacent cutterhead.

The utility model high speed twin shaft stubble cleaner is set up in parallel two paring shafts before and after adopting, and front and back two row's stubble-cleaning cuttves are worked simultaneously.Because two row's stubble-cleaning cutter radiuss of turn are inequality, but the crops on the face of front axle stubble-cleaning cutter stubble-cleaning ridge, but crops root stubble under row's stubble-cleaning cutter stubble-cleaning ridge, back carries out the secondary stubble-cleaning to crops, makes stubble-cleaning thorough, has increased the stubble-cleaning degree of depth, has improved whole ground quality.The rotating speed difference of front and back paring shaft improves stubble-cleaning speed.And on the preceding paring shaft cutterhead can be set; activity is provided with the stubble-cleaning cutter on the cutterhead; during shutdown; before stubble-cleaning cutter on the paring shaft be hang, the stubble-cleaning cutter is deployed condition during work on cutterhead, the setting that interlaces of the stubble-cleaning cutter on the adjacent cutterhead; stubble-cleaning is pulverized once to be finished; smashing capability is good, reduces the damage to paring shaft, further improves whole ground quality.

Embodiment

As shown in Figure 1, 2, the utility model high speed twin shaft stubble cleaner is made up of frame 6, suspension arrangement 1, reduction box 2, preceding paring shaft 3, back stubble ploughing knife pivot 4, stubble-cleaning cutter 5, suspension arrangement is spirally connected and is fixed on the frame, reduction box is fixed on the frame, reduction box power shaft 9 is connected with tractor output shaft, reduction gearbox output shaft is connected with paring shaft by gear or sprocket wheel, and two paring shafts are by being fixed on side by side before and after the bearing block support below the frame, and stubble-cleaning cutter 5 is fixed on the paring shaft.

Shown in Fig. 3,4, the utility model high speed twin shaft stubble cleaner fixedly installs several cutterheads 7 on the preceding paring shaft, and activity is provided with 6 stubble-cleaning cuttves 8 on the cutterhead, and the stubble-cleaning cutter is evenly arranged on the cutterhead, the setting that interlaces each other of the stubble-cleaning cutter on the adjacent cutterhead.

Claims
