TECHNICAL FIELD
[0001] The utility model relates to a cutter technical field, especially a kind of anti-winding cutter shaft. BACKGROUND
[0002] In the agricultural production process, the cutter shaft of agricultural implement such as mower, straw pulverizer etc. often faces the problem of being wound by crop residues such as weeds and straws. Once the cutter shaft is wound, not only the working efficiency of the implement will be reduced, but also the machine failure may be caused, the maintenance cost and downtime are increased, and the smooth progress of agricultural operation is seriously affected. Therefore, an agricultural implement cutter shaft design capable of effectively preventing winding is urgently needed. SUMMARY
[0003] In view of the above shortcomings in the prior art, the utility model provides an anti-winding cutter shaft, which is practical in structure and convenient to popularize.
[0004] An anti-winding cutter shaft, comprising a middle shaft, a base and a blade.
[0005] The base is fixed on the middle shaft, and the base comprises three arc-shaped edges and three straight edges.
[0006] The blade is fixed on one straight edge of the base, and the blade is arranged in an inclined manner, the side edge of the blade is in a sawtooth structure, and a horizontal plate is fixed to the top of the blade.
[0007] Preferably, four groups of bases are arranged vertically along the middle shaft, and mounting holes are provided on the bases.
[0008] Preferably, two other straight edges of the base are fixed with blade two and blade three, and the side edges of the blade two and the blade three are both in a sawtooth structure.
[0009] Preferably, the blade, the blade two and the blade three are arranged in a ring array structure around the middle shaft.
[0010] The utility model has the advantages of:
[0011] Good anti-winding effect: the inclined arrangement and sawtooth structure of the blade can effectively cut the winding objects and reduce the occurrence of winding phenomenon.
[0012] High cutting efficiency: the ring array blade structure enables the cutter shaft to uniformly cut crops or plow soil during rotation, improving the work efficiency.
[0013] Simple structure, easy to install and maintain: mounting holes are provided on the base for convenient installation and fixation of the cutter shaft, and maintenance is convenient. BRIEF DESCRIPTION OF DRAWINGS
[0014] In order to more clearly illustrate the technical scheme of the embodiments of the present application, the drawings needed to be used in the embodiments will be briefly introduced as follows. It should be understood that the following drawings only show some embodiments of the present application, and therefore should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can also be obtained without creative labor on the basis of these drawings.

[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.
[0020] In the description of the embodiments of the present application, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, or the orientation or positional relationship of the product of the present application when it is usually placed, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" and the like are only used for differentiation and cannot be understood as indicating or implying relative importance.
[0021] In addition, if the terms "horizontal", "vertical", "overhanging" and the like appear, they do not mean that the components must be absolutely horizontal or overhanging, but can be slightly inclined. For example, "horizontal" only means that its direction is relatively more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.
[0022] Embodiment 1
[0023] The utility model discloses an agricultural implement anti-winding cutter shaft, including the axle 1, base 2 and blade 3.
[0024] The base 2 is fixed on the axle 1, and the structure is unique, including three arc edges and three straight edges. The special shape design makes the base better guide airflow and the trend of cutting material during rotation, reduces the possibility of winding.
[0025] The blade 3 is fixed on one straight edge of the base 2 and is arranged in an inclined manner. The inclined blade can make the cut material be thrown out more easily by using its angle during cutting, instead of accumulating around the cutter shaft. In addition, the side edge of the blade 3 is in a sawtooth structure, which greatly enhances the cutting ability, and can efficiently cut off both tough straw and dense weeds. Furthermore, the top of the blade 3 is fixed with a horizontal plate 4, which can play a role in adjusting balance.
[0026] Further, the base 2 is arranged vertically along the axle 1 and is provided with four groups. The arrangement of multiple groups of bases increases the cutting points, improves the work efficiency, and disperses the risk of material winding. In addition, the base 2 is provided with a mounting hole 5, which facilitates the fixing and installation of the base and the axle and subsequent disassembly and maintenance.
[0027] Embodiment 2
[0028] On the basis of embodiment 1, two other straight edges of the base 2 are fixed with blade two 6 and / or blade three 7, and the side edges of the blade two 6 and / or blade three 7 are in a sawtooth structure. In this way, the blades on the three straight edges work cooperatively and cut the material entering the working range of the cutter shaft from all directions, greatly reducing the probability of the material winding around the cutter shaft due to not being cut off in time. Moreover, the blade 3, the blade two 6 and the blade three 7 are arranged in a ring array structure around the axle 1, which ensures that the cutting force in all directions is uniform when the cutter shaft rotates, and the cutting effect is stable.
[0029] The above only describes the preferred embodiments of the utility model patent, and does not limit the utility model patent, and any modification, equivalent replacement and improvement made within the spirit and principle of the utility model patent should be included in the protection scope of the utility model patent.
