Description
Technical field
The utility model relates to agricultural machinery technological field, particularly relates to a kind of rotary tiller shaft.
Background technology
Rotovator is important agricultural machinery, in agricultural modernization farming, have important effect.The whirler of existing intermediate transmission version, centre arranges transmission case, and rotary tiller shaft two ends arrange bearing, drives rotary tiller shaft to rotate carry out farming at the effect lower transmission case of bearings at both ends.Rotavator knife axle assembly comprises cutter shaft and rotary blade, and cutter shaft comprises axis body and is arranged on the tool rest of axis body circumferential outer surface, and rotary blade is arranged on the tool rest of cutter shaft.The axis structure form of existing cutter shaft and shortcoming: 1, directly adopt real core round steel version, the shortcoming of this structure: material consumption is many, manufacturing cost is high; 2, central siphon is adopted in the middle of axis body, two spindle noses are welded at central siphon two ends, spindle nose installs bearing, the shortcoming of this structure: central siphon and spindle nose solder technology require high, keep away and unavoidably occur weld defect, there is welding stress, affect the whole service life of cutter shaft, and be fixed together, when central siphon or spindle nose need be changed by the mode of welding due to central siphon and spindle nose, supportingly need change together, cause manufacturing cost high.
Utility model content
The purpose of this utility model is just to overcome the deficiencies in the prior art, provides a kind of reasonable in design, low cost of manufacture, mounting or dismounting change rotary tiller shaft easily.
To achieve these goals, the utility model provides a kind of rotary tiller shaft, and comprise central siphon and two spindle noses, described central siphon in tubular construction, the circumferential inner wall at central siphon two ends is provided with internal thread and internal thread escape, and the outer circumferential walls at internal thread place is provided with screwed hole; One end of described spindle nose is provided with the external screw thread matched with described central siphon internal thread, and the outer circumferential walls at external screw thread place is provided with the screwed hole identical with described central siphon screwed hole size, the two ends two spindle noses being connected to described central siphon are coordinated by internal and external threads, after central siphon is threaded with spindle nose, the screwed hole of described central siphon is relative with the screwed hole position of described spindle nose, and holding screw is installed on the screwed hole place of central siphon and spindle nose.
Further, the outer circumferential walls of described central siphon is provided with tool rest, is connected on central siphon by rotary blade by tool rest.
Further, the screwed hole quantity that described central siphon outer circumferential walls is arranged is 1 ~ 4, and the circumferentially uniform setting of outer wall of each screwed hole; The screwed hole quantity that corresponding described spindle nose outer circumferential walls is arranged is 1 ~ 4, and the also circumferentially uniform setting of outer wall of each screwed hole.
The beneficial effects of the utility model: central siphon of the present utility model is threaded with spindle nose, the mounting or dismounting of this structure are convenient, without the need to supporting replacing, low cost of manufacture; For preventing central siphon and spindle nose, in rotary course, occur phenomenons such as getting loose, the utility model is provided with screwed hole on central siphon and spindle nose, and holding screw is arranged on the screwed hole place of central siphon and spindle nose, the relative rotation of restriction central siphon and spindle nose.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the utility model embodiment.
Above-mentioned Reference numeral:
1, central siphon; 2, holding screw; 3, spindle nose; 4, tool rest.
Embodiment
Below in conjunction with accompanying drawing, utility model is further illustrated, but be not used for limiting scope of the present utility model.
Embodiment
As shown in Figure 1, a kind of rotary tiller shaft that the utility model provides, comprise central siphon 1 and two spindle noses 3, described central siphon 1 is in tubular construction, the circumferential inner wall at central siphon 1 two ends is provided with internal thread and internal thread escape, and the outer circumferential walls at internal thread place is provided with screwed hole; One end of described spindle nose 3 is provided with the external screw thread matched with described central siphon 1 internal thread, and the outer circumferential walls at external screw thread place is provided with the screwed hole identical with described central siphon 1 screwed hole size, the two ends two spindle noses 3 being connected to described central siphon 1 are coordinated by internal and external threads, after central siphon 1 is threaded with spindle nose 3, the screwed hole of described central siphon 1 is relative with the screwed hole position of described spindle nose 3, and holding screw 2 is installed on the screwed hole place of central siphon 1 and spindle nose 3.The outer circumferential walls of described central siphon 1 is provided with tool rest 4, is connected on central siphon 1 by rotary blade by tool rest 4.
The screwed hole quantity that described central siphon 1 outer circumferential walls is arranged is 1 ~ 4, and the circumferentially uniform setting of outer wall of each screwed hole; The screwed hole quantity that corresponding described spindle nose 3 outer circumferential walls is arranged is 1 ~ 4, and the also circumferentially uniform setting of outer wall of each screwed hole.In embodiment shown in Fig. 1, central siphon 1 is all only provided with one with the screwed hole on spindle nose 3, the quantity situation setting according to actual needs of screwed hole.Quantity more anti-rotations effect of screwed hole is better.
Central siphon 1 of the present utility model is threaded with spindle nose 3, and the mounting or dismounting of this structure are convenient, without the need to supporting replacing, and low cost of manufacture; For preventing central siphon 1 and spindle nose 3, in rotary course, occur phenomenons such as getting loose, the utility model is provided with screwed hole on central siphon 1 with spindle nose 3, and holding screw 2 is arranged on the screwed hole place of central siphon 1 and spindle nose 3, the relative rotation of restriction central siphon 1 and spindle nose 3.
