Abstract
The utility model relates to an agricultural machine especially relates to a novel hay cutter, including the frame, be equipped with sprocket conveying roller, feed roller, toolbox in proper order in the frame from between feed inlet to the discharge gate, the toolbox lower part is equipped with bellows, is equipped with complex upper and lower dancing roll, characterized by with it on the feed roller: two fixed cutter heads are arranged at two ends of the rotating shaft in the cutter box, the cutter body of the hay cutter and the axis of the rotating shaft in the cutter box are spirally arranged, and the cutting edge is approximately parallel to the axis of the main shaft; the utility model discloses a change into spiral tooth type sword to the hand hay cutter, decomposed the atress peak, reduced work torsion.
Description
Technical field
The utility model relates to a kind of farm machinery, especially relates to a kind of circular knife hay cutter.
Background technology
Along with China's Developing of Animal Industry, increasing peasant household generally adopts hay cutter, although existing large-scale hay cutter power is big, speed is fast, but its bulky heaviness, move very inconvenient, and for the peasant household of small-sized scale its price comparison costliness; Its volume of small-sized hay cutter is little, but it is slow to cut up with a hay cutter careless speed, and power is low, and this is because no matter present hay cutter is large-scale, still small-sized, its grass cutter all adopts is upright cutter pattern, the axis normal of the plane at blade place and rotating shaft just, and the moment of torsion of cutterhead rotation needs is big like this, thereby the power that needs is also big, original startup power needs big, the power consumption height, and the energy of consumption is many.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of direction of passing through the blade bodies of change grass cutter is provided, thereby shortens the circular knife hay cutter of the moment of torsion that is applied end.
The utility model is implemented in the following way:
A kind of circular knife hay cutter, comprise frame, in the frame from charging aperture to being provided with sprocket wheel conveying roller, feed roller, girff between the discharging opening successively, the girff front portion is provided with bellows, be provided with the bob roller that cooperates with it on the feed roller, it is characterized in that: the two ends of the inherent turning cylinder of above-mentioned girff are provided with two fixation cutter heads, the axis shape setting in the shape of a spiral of turning cylinder in the cutter hub of grass cutter and the girff, and blade is approximate parallel with the axis of main shaft.
The utility model has following effect:
The novel hay cutter that the utility model provides is that the axis normal with turning cylinder in the cutter hub of the grass cutter on the existing hay cutter and the girff changes the helical form setting into, and blade is approximate parallel with the axis of main shaft, as knife edge profit, seemingly saws power is decomposed.Under the situation of same process velocity, energy-conservation more than 50% by evidence; This hay cutter is simple in structure, and use face is extremely wide, is the new discovery of China's energy conservation project.
The grass cutter that the utility model adopts is a circular knife, cutter hub is with respect to main shaft 180 degree, double-pole is installed on main shaft relatively, grass cutter is on main shaft during rotary work like this, the zero load of 140 degree and the torsion peak of 40 degree just can not occur, guarantee when whole 360 degree rotate, to have decomposed the torsion peak, further reduce the power consumption of hay cutter, improved operating efficiency.
The utility model user can cooperate low-power work to use as required, does not have high load with small power, reduces and gets final product for the grass amount; If power breaks down, the urgently needed again forage grass of user can respectively add directed lever at the main shaft two ends, and two people alternately press down; Also can add upper lever at main shaft one end, single pressing down just played the grass cutter effect, and also not choosing grazes.

Embodiment
A kind of novel hay cutter, as shown in Figure 1, comprise frame 8, frame 8 interior sprocket wheel conveying roller 5, feed roller 9, the girffs 2 of being provided with successively between 1 from charging aperture 6 to discharging opening, girff 2 bottoms are provided with bellows 10, be provided with the bob roller 4 that cooperates with it on the feed roller, the two ends of girff 2 inherent turning cylinders 11 are provided with two fixation cutter heads 12, the axis shape setting in the shape of a spiral of turning cylinder 11 in the cutter hub of grass cutter 3 and the girff 2; Blade is approximate parallel with the axis of main shaft; Material enters from charging aperture 6, under the drive of sprocket wheel conveying roller 5, enters in the girff 2 under the cooperation of bob roller 4 and feed roller 9, and material, is sent from discharging opening 1 under the effect of bellows 10 through behind the girff 2.
