Description
Technical field
The utility model belongs to agricultural machinery technological field, relates to a kind of reducing mechanism, is specifically related to a kind of vertical L-type banana straw chopping and returning flail mechanism.
Background technology
Banana is one of fruit of liking the most of people, and along with the development of banana industry, its main by product banana stalk also increases day by day, is mainly chopping and returning at present to the processing of these straw refuses, realizes and makes full use of resource, increases also field of green manure.
Existing banana straw crushing and field-returning machine mainly contains two kinds, horizontal machine and vertical machine, and the field-returning machine of domestic production is mostly horizontal field-returning machine.The cutter shaft of horizontal machine reducing mechanism is parallel to the ground, is generally arranging many group blades on cutter shaft, but the imbalance of its arrangement or unbalance stress all can make cutter shaft produce in the time of work uneven, thereby causes the vibration of complete machine.And there is certain arranging density between horizontal machine knife axle cutter, cause and rotate the winding obstruction that more easily occurs fiber, weeds on cutter shaft.
The shape of the flail knife of banana straw crushing and field-returning machine and operating type will directly affect the pulverizing q&r of straw crushing and field-returning machine.At present, the shape of flail knife mainly contains: straight knife type flail knife, hammer is grabbed formula flail knife, Y type flail knife, T-shaped flail knife and whip formula flail knife, but the design of these flail knives is mainly for corn, Chinese sorghum, the hard stalk that the canes such as cotton are thinner, and it is sturdy to cane, moisture content is higher, three major polymers: cellulose, the banana stalk of hemicellulose and lignin composition is not also developed more ripe crushing knife, and these flail knives are generally due to the necessary long-time and stalk of cutter, the harder objuct body contacts such as soil, can cause the heavy wear of knife edge part, cause seriously shorten service life, the wearing and tearing of flail knife cutting edge also can have influence on the crushing effect of stalk in addition.
Utility model content
The purpose of this utility model is to provide a kind of vertical L-type banana straw chopping and returning flail mechanism for the deficiencies in the prior art, adopting vertical L-type flail knife to have increased amasss the tangent plane of beating of stalk, can realize good crushing effect, not only can effectively reduce the winding of stalk fibre to cutter shaft, be suitable for as the reducing mechanism for banana straw crushing and field-returning machine device.
The technical scheme that the utility model adopts:
A kind of vertical L-type banana straw chopping and returning flail mechanism, comprise tool rest, described tool rest is made up of rectangular upper steel plate and lower steel plate, the corresponding interval stack of upper steel plate and lower steel plate two ends also connects firmly by the cylinder bloom at middle part, make it have spacing distance, between upper steel plate and lower steel plate, connect firmly block in the both sides of two ends and connection pin is set, the top, middle part of upper steel plate arranges rectangular box, and the left and right sides of rectangular box arranges support floor; In the rectangular box of tool rest, be provided with vertical cutter shaft, between upper steel plate and lower steel plate, connect firmly L-type flail knife by connecting pin respectively in two ends, utilize upper and lower steel plate clamping, the spacing firmly L-type flail knife that stops of both sides block, prevent from occurring in operation process loosening, while ensureing that L-type flail knife runs into stalk reaction force in the process that impacts stalk, can stressed retraction and affect crushing effect.
Described L-type flail knife is made up of construction section and profiling active section, and several installing holes are set on construction section, can be according to the extension elongation of regulating working conditions L-type flail knife, and by two, different radii, the excentric arc section of bending form profiling active section downwards.
The utility model is simple in structure, adopting vertical L-type flail knife to have increased amasss the tangent plane of beating of stalk, can realize good crushing effect, not only can effectively reduce the winding of stalk fibre to cutter shaft, also can reduce the consumption of machine power because of the minimizing of mounting cutter quantity, and between flail knife and tool rest, adopt pin to connect, can be convenient to the disassembling, assembling and replacing of flail knife, mounting or dismounting are convenient, are suitable for as the reducing mechanism for banana straw crushing and field-returning machine device.
