Abstract
The utility model relates to a hay cutter with a circular-arc curved blade, which comprises a frame (1), a main shaft (2), a cutter head (3), a fixed blade (4), a rotary blade (5) and a compression bolt (6), and is characterized in that the cutter body (7) of the rotary blade (5) is circular-arc-shaped and is provided with an inclined cutting edge (8); and a cutter ejecting screw (9) corresponding to the compression bolt (6) is arranged on the cutter head (6). The utility model changes the straight cutter body into a circular-arc shaped blade, gently shears straws instead of strongly cutting, and moreover, the rotary blade and the fixed blade cut from one end, so that the original line contact between the fixed blade and the rotary blade of the hay cutter is changed into the point contact therebetween, the shearing force is reduced, the hay cutting operation is gentle and labor-saving, and the energy is saved.
Description
Technical field
The utility model belongs to the agricultural machinery field, relates in particular to a kind of hay cutter.
Background technology
Agricultural goes up the hay cutter of using at present, is mostly fixed blade is set on frame the corresponding rotating blade that is provided with fixed blade on cutterhead.Rotating blade mostly is the straight knife body, and level is installed on the cutterhead, by speed and brute force stalk is blocked, and this machines cumbersome, the hand hay cutter grass is slow, and power consumption is big, and efficient is low, does not meet the green agriculture plan of national low-loss and energy-saving.
Summary of the invention
The utility model is the shortcoming that overcomes above hay cutter, utilizes scissors to cut the principle of cloth, and a kind of circular arc tulwar hay cutter is provided.Technical solution adopted in the utility model is such: the utility model includes frame, main shaft, cutterhead, fixed blade, rotating blade and hold-down bolt, the cutter hub of rotating blade is circular-arc and is provided with the oblique edge of a knife, corresponding with hold-down bolt, on cutterhead, be provided with top cutter screw.The effect of top cutter screw is to be used for regulating the gap of rotating blade and fixed blade and to cooperate hold-down bolt that rotating blade is pressed on the cutterhead.
The utility model becomes circular-arc blade with the straight knife structural reform, change pound disconnected stalk rigidly as shearing mildly into, and, rotating blade and fixed blade are gone into from an end-grain cutting earlier, line by original hay cutter moving knife and stationary knife contacts like this, and the point that has made moving knife and stationary knife into contacts, and shearing force reduces, soft laborsaving during the hand hay cutter grass, energy savings.
Description of drawings
Fig. 1 is the front view of structural representation of the present utility model;
Fig. 2 is the end view of structural representation of the present utility model.
Among the figure, 1, frame, 2, main shaft, 3, cutterhead, 4, fixed blade, 5, rotating blade, 6, hold-down bolt, 7, cutter hub, 8, the oblique edge of a knife, 9, top cutter screw.
Embodiment
With reference to accompanying drawing, embodiment of the present utility model is described further: the utility model includes frame 1, main shaft 2, cutterhead 3, fixed blade 4, rotating blade 5 and hold-down bolt 6, the cutter hub 7 that it is characterized in that rotating blade 5 is circular-arc and is provided with the oblique edge of a knife 8, with the hold-down bolt 6 corresponding top cutter screws 9 that are provided with on cutterhead 3.
During the hand hay cutter grass, grass is placed on the fixed blade 4, the rotating blade 5 of rotation can be sheared grass disconnected.
