Abstract
The utility model provides a field straw chopper. Reciprocating type short cutting knives are additionally arranged on cutting knife discs, and the short cutting knives and long cutting knives are arranged in a staggered mode. When the short cutting knives rotate, incoming straws are cut and smashed, and the straws cut off by the long cutting knives are cut and smashed again, thereby smashing effect of the cutting knife discs with the long cutting knives and the short cutting knives is better than that of the cutting knife discs only provided with the long cutting knives. The cutting knife discs on two outer sides are in chain transmission and work more stably than belt transmission does, and compared with those in belt transmission, the cutting knife discs in chain transmission can overcome greater working resistance. A traction frame and a side support can be dismantled, thereby facilitating transportation. The cutting knife discs and a transmission shaft are connected through bolts and flanges, thereby being convenient to dismantle and replace. The cutting knife discs on two outer sides and a main cutting knife disc are connected with each other through bolts and can be dismantled or installed according to conditions, and accordingly, the field straw chopper is suitable for use in different terrains and tractors with different horse powers and wider in applied range.

The utility model relates to a kind of straw cutting apparatus, belongs to field of agricultural machinery.
Background technology
In the agricultural production process; There is huge demand in also field to stalk, and 200920140295.7 patents have been announced a kind of straw cutting apparatus, but the increase and decrease of cutter disc groups quantity is inconvenient; The effect of blade cuts stalk needs further to improve, and the transmission of both sides cutterhead is not steady.
The utility model content
The technical problem that the utility model will solve is to overcome existing defective, and a kind of straw cutting apparatus is provided, and can increase and decrease cutter plate quantity easily, and improves cutting effect, improves the transmission effect of both sides cutter plate.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of straw cutting apparatus comprises frame, transmission system, cutter disc groups, and transmission system comprises bevel gear wheel and bevel pinion, spur gear; Bevel gear wheel and bevel pinion engagement, the power transmission shaft lower end of bevel pinion is set with spur gear, and five spur gears arranged side by side mesh successively; The power transmission shaft upper end of the spur gear of both sides is equipped with first drive; The lower end is equipped with the main body cutter plate, and first drive connects second drive through transmission device, and the power transmission shaft bottom of second drive connects outside cutter plate; Said first drive and second drive are sprocket wheel, and the transmission device between it is a chain; Be fixedly connected through bolt and flange between said outside cutter plate and main body cutter plate; Said cutter plate is through connecting through bolt between the power transmission shaft; Said cutter plate is divided into movable knife disc, following movable knife disc and stationary knife dish, and long cutter and short cutter are installed on the said upper and lower movable knife disc, and the stationary knife dish is fixedly connected with frame; Said frame front is connected with dismountable hitch frame through bolt, side stand, and the frame back is installed with pressing roller.
A kind of straw cutting apparatus of the utility model has increased reciprocating type short cutter newly on cutter plate, with the arrangement that interlaces of long cutter.When short cutter rotates: the one, the stalk of coming in is carried out cutting and grinding; The 2nd, to being carried out cutting and grinding once more, like this than the good crushing effect of the cutter plate that has only long cutter by the stalk after the cut-out of long cutter.Two outside cutter plates adopt chain drive, and are more stable during than belt work, and are with transmission, can overcome bigger working resistance; Hitch frame, side stand can be dismantled, convenient transportation.Cutter plate adopts bolt, flange to be connected with power transmission shaft, is convenient to dismounting and change, and the cutter plate in two outsides adopts bolt to be connected with the main body cutter plate, can according to circumstances dismantle or install, and is fit to different terrain and uses with different horsepower tractors, and range of application is wider.
