Description

A kind of wide cut straw cutting apparatus

Technical field:

The utility model relates to farm machinery, further is straw-returning machinery.

Background technology:

There is following problem in many straw cutting apparatuss on the market because design is unreasonable: one, the liter of traditional field-returning machine with fall, be to rely on the degree of tightness of driving-belt to realize, when field-returning machine raise, driving-belt was lax, occurred easily instead being with, the tape wrap phenomenon; And the main frame castle wheel is running well during lifting, and driving-belt is slowly motion generation friction in sheave, and driving-belt is damaged.Its two, at present straw cutting apparatus is when the row of operation limit, front and back wheel must be walked on the furrow ridge, because of the hammer pawl buries, machine power consumption is big, rotating speed descends, crushing effect is poor.

Granted patent " rack construction of straw cutting apparatus " (patent No. is ZL200520030694.X) has solved above problem preferably in person.But, still there is following problem: one, the width of the field-returning machine axle core of design is about 90 centimetres, be about 3/8 of corn planting one furrow width, make that one furrow operation need be carried out three times, does not operate at full capacity for the last time when carrying out the maize straw operation, efficient is low, causes the waste of the man-hour and the energy.Its two, the height of stalk stubble is inequality often, when the field-returning machine operation, because roll adopts fixing design, it is improper easily to cause flail knife or hammer pawl to contact with ground, or far away apart from ground, influences the operation cleanliness; Or embedded depth is dark excessively, causes the wearing and tearing aggravation of flail knife or hammer pawl, also causes the waste of the energy.

Summary of the invention:

The straw cutting apparatus that the purpose of this utility model provides is easy to operate, farming is effective, efficient is high.

The purpose of this utility model realizes by following scheme: a kind of wide cut straw cutting apparatus, comprise casing, preceding hitch frame, the main shaft in the casing and the roll behind the casing of casing, be characterized in: a side of the casing of straw cutting apparatus is equipped with drive A, top at casing, be installed with two bearing blocks and the bearing A of an A in being fixed with, the two ends of axle A are equiped with drive B and drive C respectively, there is link the hitch frame front portion, bearing block and bearing B are fixed on the hitch frame, and bearing block and bearing C are fixed on the link; Pass a B in bearing block and bearing B, C, the two ends of axle B are equiped with drive D and castle wheel respectively, and castle wheel is connected with the tractor dynamic power wheel by belt, and drive D joins by belt and drive C, and drive B joins by belt and drive A.

The utility model can be designed to 1.25-1.30 rice with the axle core width of field-returning machine.

The utility model can be provided with the roll adjuster.

The outstanding advantage of the utility model is: 1, can finish the also field operation of furrow for twice, efficient is 1.5 times of general straw cutting apparatus.2, roll is adjustable, and when making also field operation, the hammer pawl of field-returning machine or flail knife and ground are in best distance, thereby can reduce the friction with ground, improves the service life of hammering pawl and flail knife into shape, cuts down the consumption of energy.3, castle wheel can separate the field-returning machine duty at any time, is convenient to starting and turning; Play the effect of saving the energy, and improve safety coefficient.4, when lifting, be the center of circle with the line shaft, distance between all wheels such as field-returning machine castle wheel and tractor castle wheel and main shaft power wheel remains unchanged, adopt pinch roller and carrier wheel simultaneously, thereby avoided the belt slack phenomenon, thereby the phenomenon that can therefore not cause belt to damage.Make things convenient for the tiller, saved fund.
