Technical Field
The utility model relates to a sesame stem stalk cutting technical field, especially a reciprocating type harvester cutting knife based on sesame stem stalk characteristic.
Background
At present, the cutting tools of the sesame harvesting machine mostly adopt common cutting knives, the working load is large, the cutting effect is poor, and the loss before cutting is large. Although the cutting of thin stalks is realized, the thick stalks are not easily cut off, so that the problems of high pre-cutting loss, poor cutting effect, poor adaptability of a cutting knife, low operation efficiency and the like are caused, the harvest cost of farmers is improved, huge loss is caused, and the development of the sesame industry is severely restricted.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problems of unstable operation of the cutting knife, poor cutting effect, high energy consumption, low speed and the like in the existing sesame harvesting device, and designing a reciprocating harvester cutting knife based on sesame stalk characteristics.
In order to achieve the above object, the technical scheme of the utility model be, a reciprocating type harvester cutting knife based on sesame stem stalk characteristic, including the frame, still include reciprocating motion's cutting knife subassembly and the supporting component that the several of immobility arranged in proper order, wherein: the cutting knife assembly includes: the cutter bar is arranged on the rack through a reciprocating mechanism; the movable blades are sequentially arranged on the cutter bar; the support assembly includes: the fixing part is fixedly connected with the rack; the tip part is positioned at the foremost end of the cutting knife and used for guiding and collecting the stalks; the cutting part is connected with the fixing part and the tip part, and the side surface of the cutting part is arranged to be in a blade shape; and the pressing edge part is connected with the tip part, and the movable blade is movably arranged between the pressing edge part and the cutting part. Through the high-speed reciprocating motion of cutting knife, increase cutting dynamics makes the stem stalk receive bigger impact, and cutting effect is better, has solved the sesame when reaping stem stalk cutting inhomogeneous, the consumption is big, the high scheduling outstanding problem of loss rate before cutting, has improved the efficiency of reaping of sesame, has promoted the development of the sesame industry high-quality efficient more.
Further, the fixing part is arranged on the rack in a riveting mode.
Furthermore, the movable blade is a trapezoidal blade with a bevel tooth edge.
Furthermore, the movable blades are arranged on the cutter bar in a straight line shape.
Furthermore, the movable blades are arranged on the cutter bar in an arc shape.
Further, the tip portion is tapered.
The utility model has the advantages that: the cutting of the passed stalks achieves the effect of effectively separating the stalks from the roots, solves the problems of poor effect of cutting off the sesame stalks, irregular stubble, large loss before cutting, high harvesting cost and the like in China at present, and is suitable for big and small sesame harvesting machines in China. Through the combination of the movable blade and the cutting part, the stalks are stressed properly, and the harvesting efficiency is high. Through the high-speed reciprocating cutting motion, the shearing force borne by the stems is increased, the stems are cut off quickly, the overall performance of the sesame combine harvester is improved, and the high-quality and high-efficiency development of the sesame industry is promoted.

Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose of the present invention, the following detailed description is given to the embodiments, structures, features and effects according to the present invention with reference to the accompanying drawings and preferred embodiments as follows:
the idea of this application is, according to some intrinsic characteristics of stems such as sesame itself, combine together the lateral motion and the seesaw of cutting knife, reach the best cutting effect, solve the sesame and reap the outstanding problem such as stem cutting atress is uneven, frictional force is big, the consumption is big, reduce the sesame and reap the loss before the cutting, reduction in production cost promotes the sesame industry development.
A reciprocating harvester cutter based on sesame stalk characteristics is shown in figures 1 to 7 and comprises a frame 1, a reciprocating cutter assembly 2 and a plurality of fixed support assemblies 3 which are arranged in sequence.
With combined reference to fig. 4-6, the cutter assembly 2 includes a cutter bar 21 and a plurality of movable blades 22. The cutter bar 21 is arranged on the frame 1 through a reciprocating mechanism, and a plurality of movable blades 22 are arranged on the cutter bar 21 in sequence.
In fig. 1 to 3, the movable blades 22 are arranged in a straight line on the cutter bar 21, and the arrangement is low in manufacturing cost. Or the movable blades 22 are arranged on the cutter bar 21 in an arc shape, the processing cost of the arrangement mode is a little higher, but the action effect is obvious, and the action of furling the stems can be obviously enhanced. When the knife bar 21 reciprocates, the movable blade 22 disposed on the knife bar 21 also reciprocates therewith. This application provides a movable blade 22 shape as shown in fig. 6 according to actual conditions, and it is trapezoidal for the skewed tooth sword, and of course, it also can be triangle-shaped, but the trapezoidal intensity of skewed tooth sword is higher, avoids the too fast wearing and tearing of unilateral skewed tooth sword under the effect of stem, long service life, and work quality is high.
As shown in fig. 4, 5 and 7, the support member 3 includes a fixing portion 31, a tip portion 32, a cutting portion 33 and a blade portion 34. The fixing portion 31 is fixedly connected to the frame 1, and may be connected by riveting. The tip part 32 is positioned at the most front end of the cutting knife, and the tip part 32 is conical and used for guiding and collecting the stalks, so that the operation efficiency is improved. The cutting portion 33 connects the fixing portion 31 and the tip portion 32, and the side surface of the cutting portion 33 is provided in a blade shape. The pressing edge part 34 is connected with the tip part 32, the movable blade 22 is movably arranged between the pressing edge part 34 and the cutting part 33, the pressing edge part 34 participates in cutting stress, the movable blade 22 is prevented from deviating, the shaking amplitude of the movable blade 22 is reduced, and the stability of the movable blade 22 is improved.
In operation, the movable blade 22 reciprocates such that the tip 32 thereof divides the stems of sesame into small bundles and guides the small bundles to the movable blade 22, and the movable blade 22 pushes the stems toward the cutting portion 33 during the movement to perform a cutting operation.
The invention has been described above with reference to a preferred embodiment, but the scope of protection of the invention is not limited thereto, and various modifications can be made and equivalents can be substituted for elements thereof without departing from the scope of the invention, and features mentioned in the various embodiments can be combined in any way as long as there is no structural conflict, and any reference sign in the claims should not be construed as limiting the claim concerned, and the embodiments should be regarded as being exemplary and non-limiting in any way whatsoever. Therefore, all technical solutions that fall within the scope of the claims are within the scope of the present invention.
