Abstract
The utility model relates to a cutter shaft of a ditcher, which comprises a cutter shaft body, wherein 12 tool aprons are welded in the middle of the cutter shaft at equal intervals; two tool aprons are welded on the two sides of the cutter shaft respectively; five pairs of aprons are welded in the middle in a centrosymmetric manner and with an angle difference of 60 degrees between adjacent pairs; 12 ditching knives are arranged at the upper ends of the tool aprons; the tool aprons are screwed with the ditching knives through two groups of mounting holes; the ditching knives comprise upper tool arms and lower tool arms; the upper tool arms are rectangular; the mounting holes are formed in the surfaces of the upper tool arms; the lower tool arms are bent from the roots of the lower tool arms to the ends of the lower tool arms to be arc; the ditching knives are arranged to be left ditching knives and right ditching knives. The cutter shaft provided by the utility model is simple in structure, reasonable in design, convenient to mount, low in cost, and long in service life. In practical use, the ditching knives are stressed uniformly, and the cutter shaft is small in load, so that the service life of the cutter shaft can be prolonged, and the cutter shaft of ditcher is of great practicability.
Description
Technical field
The utility model relates to ditching machine technical field, especially a kind of ditching machine cutter shaft technical field.
Background technology
Existing ditching machine cutter shaft, as the core component of ditching machine, has important impact to the trench digging in farmland, ditching machine general with walking tractor matching use, the middle trench digging of advancing in field, the running of ditching machine cutter shaft, directly affects the production efficiency of ditching machine.At present, the existing cutter shaft in market is mostly 14 ditching knifes, is and is welded on side by side on cutter shaft, and how but production efficiency is slow for quantity, and power consumption is large, and cutter shaft structure complexity, installs loaded down with trivial details.
, there is following shortcoming in the ditching machine cutter shaft of prior art:
1. prior art is being used 14 ditching knife, and assembly cost is high;
2. prior art complex structure, parts are worse frequent, inefficiency;
3. prior art tool rest is welded on axle side by side, makes the stressed large of cutter shaft.
Summary of the invention
For the problems referred to above, it is a kind of simple in structure, reasonable in design, easy for installation that the utility model provides, the ditching machine cutter shaft of the low and long service life of cost.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of ditching machine cutter shaft, comprise cutter shaft, its design feature is: described cutter shaft middle part is provided with equally spaced 12 tool rests and is welded, described tool rest two sides are welded respectively one, the centrosymmetric 5 groups of tool rests of middle part welding, and between tool rest, increase progressively successively 60 ° of arrangements, the upper end of described tool rest is provided with 12 ditching knifes, described tool rest and ditching knife are by two groups of installing hole bolted on connections, and described ditching knife is provided with tool arm and lower tool arm.
Further, described upper tool arm is made as rectangle, and surface is provided with installing hole, and described lower tool arm is convexly curved to end from its root.
Further, described ditching knife is made as respectively left ditching knife and right ditching knife.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, easy for installation, the low and long service life of cost.The in the situation that of equal trench digging effect, the utility model only needs 12 ditching knife can be reached, and only needs a few minutes can complete assembling in the installation of cutter shaft, and cutter shaft overall volume is little, is applicable to various transportation environments; In actual use, ditching knife is stressed evenly, and cutter shaft load is little, is conducive to extend the service life of cutter shaft, has practicality.
Accompanying drawing explanation
The accompanying drawing that forms the application's a part is used to provide further understanding of the present utility model, and schematic description and description of the present utility model is used for explaining the utility model, does not form improper restriction of the present utility model.
Fig. 1 is structural representation of the present utility model.
In figure: 1. cutter shaft, 2. tool rest, 3. ditching knife, 4. left ditching knife, 5. right ditching knife, 6. goes up tool arm, 7. descends tool arm, 8. bolt, 9. nut, 10. installing hole, 11. axle sleeves.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment
The preferred embodiment of the utility model ditching machine cutter shaft as shown in Figure 1, comprise cutter shaft 1, cutter shaft 1 middle part is provided with equally spaced 12 tool rests 2 and is welded, tool rest 2 two sides are welded respectively one, the centrosymmetric 5 groups of tool rests 2 of middle part welding, and 2 of tool rests increase progressively 60 ° of arrangements successively, the upper end of tool rest 2 is provided with 12 ditching knifes 3, tool rest 2 passes through two groups of installing hole 10 bolted on connections with ditching knife 3, ditching knife 3 is provided with tool arm 6 and lower tool arm 7, upper tool arm 6 is made as rectangle, and surface is provided with installing hole 10, lower tool arm 7 is convexly curved to end from its root, ditching knife 3 is made as respectively left ditching knife 4 and right ditching knife 5.
The arrangement mode of 12 tool rests 2, in the time of running, make cutter shaft stressed more even, thereby increase the fastness of cutter shaft, make longer service life, ditching knife 3 is socketed in tool rest 2, and two groups of installing holes 10 are alignd, and then respectively bolt 8 is passed from a side, and connect fixing with nut 9, distinctive 12 groups of ditching knifes make cost lower, inverted sequence operation when dismounting, easy accessibility.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to claim scope.
