Description

A kind of interchangeable flail knife formula straw millstone
Technical field
The utility model relates to a kind of interchangeable flail knife formula straw millstone, belongs to agricultural machinery technological field.
Background technology
Present existing reaping machine mostly is equipped with straw millstone, and the purpose that straw millstone is installed is in harvesting crops the field also to be gone back in the crops straw cutting and grinding.The straw millstone of existing reaping machine is made of the moving knife of stationary knife and rotation, and a cover mechanism can only pulverize a kind of crops straw, such as single pulverizing cotton stalk, and perhaps single crushing maize stalk, perhaps single pulverizing wheat stalk.Physical propertys such as the strain footpath of cotton, corn and wheat stalk, plant height, toughness have a great difference, and cotton stalk strain footpath is thicker, and plant height is higher, and cane is tough and tensile; Maize straw strain footpath is thicker, and plant height is higher, and cane is tough and tensile and crisp; Wheat stalk strain footpath is thinner, and plant height is shorter, and cane is pliable and tough.When pulverizing cotton or maize straw as the reducing mechanism of using the pulverizing wheat stalk, be short of power, crushing effect is bad, and toothing is higher, and the stalk length uniformity of pulverizing is relatively poor, is unfavorable for also field.If with the stalk of crushing maize or cotton stalk reducing mechanism pulverizing wheat, because the strain of wheat footpath is thinner, plant height is shorter, cane is pliable and tough, causes wheat stalk to twine reducing mechanism, and the reducing mechanism cutter shaft blocks up.Therefore, need buy cotton stalk reducing mechanism, wheat stalk reducing mechanism and maize straw reducing mechanism simultaneously, increase acquisition cost for the quality that guarantees straw-returning.Exchange flail knife formula straw millstone and can satisfy of the requirement of Different Crop stalk, reduce the cost that peasant household buys reducing mechanism, realize a tractor serves several purposes reducing mechanism.
Summary of the invention
The purpose of this utility model is that the type of changing flail knife satisfies the requirement of Different Crop stalk to reducing mechanism, reduces the cost that peasant household buys reducing mechanism, realizes a tractor serves several purposes.
For realizing that the technical scheme that this purpose adopts is:
A kind of interchangeable flail knife formula straw millstone, place the middle part between the reaping machine front and back wheel, comprise flail knife, the rack-mounted press wheel of frame and level, hood, wherein press wheel is installed in the rear lower of frame by sliding bearing, cutter shaft is installed on the frame by rolling bearing, 24-48 group tool rest line in the shape of a spiral evenly is fixed on the cutter shaft, three kinds of different flail knife types can be installed on the tool rest, 1 group of tool rest can be installed 1 vertical pawl formula flail knife, or 2 L type flail knives are installed, or 3 straight knife formula flail knives are installed, it is characterized in that: a kind of flail knife is the pawl formula flail knife that hangs down, and passes through bearing pin, adjusting pad and pin is fixed on the tool rest; Second kind of flail knife is L type flail knife, by adding the adjustment pad at tool rest two, is fixed on the tool rest with bearing pin and pin; The third flail knife is a straight knife formula flail knife, by add the adjustment pad between tool rest and straight knife formula flail knife, is fixed on the tool rest with bearing pin and pin.According to the flail knife type that different crops straw types can change the outfit different, adapt to the plant characteristic of crops straw, reduce power attenuation, energy savings.Straw millstone flail knife and cutter shaft are movable being hinged by bearing pin, adjustment pad and pin.
By the drawing the stem roller and pluck the effect of fringe plate the crop fruit ear is separated with stalk of the anterior ceding of Taiwan of reaping machine, and then, make stalk obtain pulverizing more fully during work through the reducing mechanism pulverizing at middle part.Can solve the pulverizing quality requirement that Different Crop stalk characteristic satisfies reducing mechanism by exchanging flail knife, reduce the cost that peasant household buys reducing mechanism simultaneously, reach effect of one machine multiple purposes.Reasonable in design, the compact conformation of this straw millstone has improved the crushed stalk rate, energy savings significantly.

Embodiment
1-6 is described in further detail in conjunction with the accompanying drawings.When reaping machine in when operation, along with advancing of the ceding of Taiwan (2), the stem roller that draws in the ceding of Taiwan (2) pulls down crops straw, and fruit ear is separated with cane, when the reducing mechanism that is positioned at the middle part advances to the stalk place, atwirl flail knife (5) cuts off pulverizing successively with stalk.This reducing mechanism (1) is by cutter shaft (11), flail knife (5), tool rest (6), hanger bracket (7) and level are installed in the press wheel (3) on the frame (8), hood (9) is formed, cutter shaft (11) is provided with spindle nose (19), in the end of spindle nose (19) passive belt wheel (20) is installed, power is transported to passive belt wheel (20) from engine output through output shaft of gear-box, the tool rest (6) that is fixed with flail knife (5) is evenly distributed on the cutter shaft (11) with the form of helix, cutter shaft (11) is a level horizontal " axle " by driving belt (20) driven rotary, helix welding tool rest (6) is pressed on the surface of cutter shaft (11), install 1 vertical pawl formula flail knife (16) between each group tool rest (6), perhaps 2 L type flail knife (17), perhaps 3 straight knife formula flail knife (18), the root of every group of flail knife (5) and cutter shaft (11) are by adjusting pad (13), pin (14) and bearing pin (15) are hinged, be that flail knife (5) is movable being connected with cutter shaft (11), have only after cutter shaft (11) high speed rotating is got up, flail knife (5) in the tool rest (6) " is got rid of " because of action of centrifugal force, the flail knife that throws up (5) has great inertia force, be scattered in this moment ground stalk promptly can by the flail knife of high speed rotating (5) continuous impact chopping, and, because flail knife (5) is movable being hinged with cutter shaft (11), so, when the flail knife (5) of high speed rotating is touching stalk or ground and is being obstructed, suitable deflection can take place for the center of circle according to pin joint (21) in flail knife (5), that is to say that flail knife (5) is equivalent to " soft " with cutter shaft (11) and is connected, rather than " firmly " of rigidity is fixedly connected.So way can effectively protect flail knife (5) not broken.At the press wheel (3) of the parallel limited dark function of device of the afterbody of reducing mechanism (1), the two ends of press wheel (3) are equipped with spindle nose (22), and are installed in the rear lower of frame (8) through sliding bearing (10), and purpose is timely compacting and smooth to be carried out on ground.The 7th, the link of reducing mechanism (1) and main frame (4).Wherein, behind the dissimilar flail knives that change the outfit, to carry out dynamic balance running.The pawl formula flail knife (16) that hangs down adopts high-strength abrasion-proof cast steel to make, and L type flail knife (17) and straight knife formula flail knife (18) adopt potassium steel to make.
