Abstract
A chain-transmission gearbox of a rotary cultivator belongs to the technical field of agricultural machinery. The chain-transmission gearbox of the rotary cultivator is simple in structure and light and can adjust the rotation speed of the rotary cultivator conveniently. The chain-transmission gearbox of the rotary cultivator is structurally characterized in that the upper portion of a box body is provided with a driving chain wheel axle, an input chain wheel and a driving chain wheel, the lower portion of the box body is provided with a spline shaft and a colter shaft chain wheel, and the middle of the box body is provided with an eccentric shaft and a tensioning wheel. A middle pull rod hanging shaft which is coaxial with the driving chain wheel axle is mounted on the upper portion of the box body, and the driving chain wheel drives the colter shaft chain wheel to rotate through chains.
Description
Technical field
The utility model belongs to agricultural machinery technological field, is a kind of rotary tillage chain transfer gear box.
Background technology
At present, the gearbox that rotovator uses is that a plurality of gear-driven gearboxes are arranged, complex structure and heaviness, and after the gearbox manufacturing moulding, the rotating speed of rotovator is unalterable.If want to adjust the cultivating quality of rotovator and the balance of fuel consumption by the rotating speed that changes rotovator, be difficult to accomplish.
Summary of the invention
The purpose of this utility model just provides a kind of rotovator gearbox by chain drive, and it is simple in structure, light, and can regulate the rotovator rotating speed easily.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of rotary tillage chain transfer gear box, it comprises casing, chain, be installed in the drive sprocket axle on casing top, be installed in input sprocket and drive sprocket on the drive sprocket axle, be installed in the splined shaft of lower box, be installed in the cutter shaft sprocket wheel on the splined shaft, be installed in the eccentric shaft at casing middle part, be installed in the expansion tightening wheel on the eccentric shaft, be installed in the middle pull bar hitching axis coaxial with drive sprocket axle on casing top, drive sprocket drives the cutter shaft sprocket rotation by chain, come the position of mobile expansion tightening wheel by the angle of regulating eccentric shaft, be used for regulating the tensioner degree of chain, regulate the rotating speed of rotovator by the input sprocket of changing the different numbers of teeth, middle pull bar hitching axis is used for the lifting of rotovator.
Compared with prior art, the beneficial effects of the utility model are: simple in structure, fault rate is low, and can accomplish to regulate the rotovator rotating speed easily according to soil property and the soil moisture content in farming farmland, thereby adjusts the balance of cultivating quality and fuel consumption well.

Fig. 2 is the end view of structural representation of the present utility model.
Description of reference numerals: (1) input sprocket, (2) casing, (3) chain, pull bar hitching axis in (4), (5) drive sprocket axle, (6) drive sprocket, (7) eccentric shaft, (8) expansion tightening wheel, (9) splined shaft, (10) cutter shaft sprocket wheel.
Embodiment
Rotary tillage chain transfer gear box design feature of the present utility model is, drive sprocket axle (5) and drive sprocket (6) are equipped with in the top of gear box (2), splined shaft (9) and cutter shaft sprocket wheel (10) are equipped with in the bottom of casing (2), the middle part setting-up eccentricity axle (7) of casing (2) and expansion tightening wheel (8).Input sprocket (1) is installed on the drive sprocket axle (5) that stretches out the casing outside, power is imported by input sprocket (1), driving drive sprocket axle (5) rotates, drive sprocket (6) is rotated, drive sprocket (6) drives cutter shaft sprocket wheel (10) by chain (3) and rotates, and splined shaft (9) is rotated finish the rotary tillage operation, thus, gearbox simple in structure, fault rate is low.By regulating the angle of eccentric shaft (7), position that can mobile expansion tightening wheel (8) is used for regulating the tensioner degree of chain (3).Middle pull bar hitching axis (4) is coaxial with drive sprocket axle (5), is installed in the outside of casing (2), is used for rising and falling of rotovator as hitch point.Regulate the rotating speed of drive sprocket axle (5) by the input sprocket (1) of changing the different numbers of teeth, thereby realize regulating easily the rotating speed of rotovator.
Claims (3)
1. rotary tillage chain transfer gear box is characterized in that: it comprises casing (2), chain (3), be installed in the drive sprocket axle (5) on casing (2) top, be installed in input sprocket (1) and drive sprocket (6) on the drive sprocket axle (5), be installed in casing (2) bottom splined shaft (9), be installed in cutter shaft sprocket wheel (10) on the splined shaft (9), be installed in casing (2) middle part eccentric shaft (7), be installed in expansion tightening wheel (8) on the eccentric shaft (7), be installed in the middle pull bar hitching axis (4) coaxial with drive sprocket axle (5) on casing (2) top.
2. gearbox according to claim 1 is characterized in that: drive sprocket (6) drives cutter shaft sprocket wheel (10) by chain (3) and rotates, and comes the position of mobile expansion tightening wheel (8) by the angle of regulating eccentric shaft (7), is used for regulating the tensioner degree of chain (3).
3. gearbox according to claim 1 is characterized in that: by the input sprocket (1) of changing the different numbers of teeth, regulate the rotating speed of rotovator.
