Abstract
The invention discloses a middle shaft structure of an agricultural shredding machine. The middle shaft structure comprises a middle shaft connected with a bearing and a driving gear. The outside of the middle shaft is sleeved by a protection sleeve. The middle shaft structure is characterized in that a blade is arranged in a cavity between the protection sleeve and the middle shaft and connected with a radial mobile mechanism; and an opening, allowing the blade to stretch out and withdraw, is arranged on the protection sleeve. By adoption of the technical scheme, the middle shaft structure of the agricultural shredding machine has following beneficial effects: the blade can stretch out during application and withdraw in an idle state so that passing-by operators can be well protected.
Description
Technical field
The present invention relates to agricultural machinery equipment field, especially relate to a kind of middle shaft structure of agricultural disintegrator.
Background technology
In modern agricultural operation, after the results crops such as paddy rice, wheat, need to reclaim straw or root out, allow it leave unused in ground and not only have influence on the nutrient cultivating but also have influence on soil in soil.
The mode rooted out for straw can adopt cutter mill when results usually, is cut by straw by blade.When using cutter mill to carry out Job Operations to straw, people can be avoided as far as possible to touch this cutter mill, prevent blade from scratching.But after fulfiling assignment, blade is still outside exposed, and passing operating personnel accidentally just can scratch.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the object of the invention is the middle shaft structure proposing a kind of agricultural disintegrator.
Object of the present invention will be achieved by the following technical programs: a kind of middle shaft structure of agricultural disintegrator; comprise: axis; described axis is connected with bearing and driven wheel; protective sleeve is provided with in the outer cover of described axis; it is characterized in that; cavity between described protective sleeve and described axis is provided with blade, and described blade is connected with radial movement mechanism, described protective sleeve offers and stretches out and the opening regained for described blade.
Preferably, the middle shaft structure of above-mentioned a kind of agricultural disintegrator, described radial movement mechanism comprises leading screw and engagement meshing gear thereon, and described leading screw is connected on described blade, and described meshing gear connection is connected to actuating unit by rotating shaft.
Preferably, the middle shaft structure of above-mentioned a kind of agricultural disintegrator, the bottom of described blade is provided with base, and described base is fixedly connected on described leading screw.
Preferably, the middle shaft structure of above-mentioned a kind of agricultural disintegrator, described opening part is set up defences backplate.
Outstanding effect of the present invention is: by arranging blade and radial expansion mechanism in protective sleeve, can regain, protect passing pedestrian after operation completes with radial expansion mechanism band knife section; When needs operation, radial expansion mechanism band knife section stretches out, and cuts; at opening part, protective plate is set; be cause it to fracture to protect blade that bending can not occur easily on the one hand, after being regained by blade on the other hand, its exposed part outside protective sleeve can not scratch people.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail the specific embodiment of the present invention, is easier to understand, grasp to make technical solution of the present invention.
Accompanying drawing explanation
Fig. 1 is the middle shaft structure schematic diagram that the embodiment of the present invention provides.
Embodiment
As shown in Figure 1; the middle shaft structure of a kind of agricultural disintegrator of the present embodiment; comprise: axis 1; axis 1 is connected with bearing 2 and driven wheel 3; protective sleeve 4 is provided with in the outer cover of axis 1; cavity between protective sleeve 4 and axis 1 is provided with blade 5, and blade 5 is connected with radial movement mechanism, protective sleeve 4 offers and stretches out and the opening 401 regained for blade 5.
Blade 5 and radial expansion mechanism are set in protective sleeve 4, can regain with radial expansion mechanism band knife section 5 after operation completes, protect passing pedestrian; When needs operation, radial expansion mechanism band knife section 5 stretches out, and cuts.
Radial movement mechanism comprises leading screw 6 and engagement meshing gear 7 thereon, and leading screw 6 is connected on blade 5, and meshing gear 7 connects and is connected to actuating unit by rotating shaft 8.
The bottom of blade 5 is provided with base 9, and base 9 is fixedly connected on leading screw 6.Be convenient to fixed blade 5 make its be not easy send out bend.
Opening 401 place sets up defences backplate 402.At opening 401, place arranges protective plate 402, is cause it to fracture to protect blade 5 that bending can not occur easily on the one hand, and after being regained by blade 5 on the other hand, its exposed part outside protective sleeve can not scratch people.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection scope of the present invention.
