Abstract
The utility model provides a speed regulating rotary cultivator, which realizes regulation according to different soils and different rotate speeds required by the cutter shaft of the cultivator in water and the dry soils so as to make the work power consumption normal. Moreover, the utility model regulates the speed by use of a middle gear of a hand chassis and a reverse gear. The utility model is characterized by simple structure, seldom fault and low cost as well as antiskid wheels with large diameters. Besides, while working in the water soil, the utility model promises no wheel-sinking, which not only provides convenient and flexible operation, but also has high efficiency as well as saving energy.
Description
The utility model relates to a kind of Speed regulating rotary cultivator, and it is applicable to the farmland ploughing operation, belongs to agricultural machinery.
Existing rotovator has appearred utilizing in domestic in recent years priority, the a tractor serves several purposes facility of the no-tillage drilling machine repacking or the transformation of the way, can carry out rotary tillage drilling lid seed, several work such as water field ploughing, being subjected to the peasant welcomes, and these multipurpose facility are when changing crops plantation, all must could realize by so-and-so parts of dismounting, to newly not purchasing the existing waste economically of person, trouble when using is arranged again, though Chinese patent ZL95240995.X rotovator function is more perfect, but need add the spreading reduction box during paddy-field-working, adding the spreading reduction box mainly is the interference of colliding of dragging the large diameter anti-pulley of installation to cause owing to hand for eliminating, and two pairs of reduction gearing in the spreading case lower the rotary ploughing cutter shaft rotating speed in addition, help reducing the operation power consumption like this.Chinese patent ZL96232262.8 water field ploughing unit, use small-sized anti-pulley instead so that do not bump interference position, with no-tillage drilling machine directly and hand drag the chassis to articulate to carry out paddy-field-working, in order to alleviate engine load, need the chain drive ratio with original 28: 12, must be adjusted into 12: 12 chain drive ratio, in recent years along with the reform of agronomy, the paddy rice kind is implanted with direct-sowing dry, water direct seeding, rice transplanting, rice transplanting etc., the rotary tillage dry land paddy field parts that need change the outfit not only bother but also waste the needs of the farming in summer that is far from suitable.
Task of the present utility model is: provide a kind of and simple in structurely can carry out speed governing according to the different rotating speeds of different soil properties and the needed rotary ploughing cutter shaft of paddy field dry farming, give full play to mechanical advantage.
Scheme of the present utility model is: a kind of Speed regulating rotary cultivator, speed governing gear-box in the middle of comprising, fast retaining gear, slowly keep off gear, driving lever, power transmission shaft, about arm housing, side driving box, rotary ploughing cutter shaft, side plate, tail wheel mechanism, fast retaining gear is housed and keeps off gear slowly on the power transmission shaft in the middle of described in the speed governing gear-box, fast retaining gear is meshed with the chassis idler gear, slowly keeping off gear is meshed with chassis I reverse gear, be the speed retaining by dialling about control stick, the centre position is a neutral, described fast retaining gear and keep off gear diameter slowly and strengthen, increase the centre-to-centre spacing between chassis driving wheel and Speed regulating rotary cultivator, large diameter anti-pulley is installed.Described tail wheel mechanism is mounted in steel part tail wheel frame and the tail wheel assembly on the Speed regulating rotary cultivator.
The utility model has the advantages that:
1, the fast retaining gear in the middle speed governing gear-box and keep off gear slowly and drag the realization speed governing that is meshed of the idler gear on chassis and I reverse gear with hand respectively, simple in structure.
2, can make required different rotating speeds according to different soil properties and floods and droughts Tagayasu Den carries out speed governing and makes the operation power consumption normal.
3, increasing is fast keeps off gear and keeps off gear diameter slowly, has increased the centre-to-centre spacing between chassis driving wheel and Speed regulating rotary cultivator, and it is paddy-field-working that the major diameter anti-pulley can be installed, and can not produce wheel clogging.
4, a machine just can be finished the farming demand in floods and droughts field, and the parts that do not change the outfit.
Be described further below in conjunction with accompanying drawing:
Fig. 1 is the utility model Speed regulating rotary cultivator drive mechanism schematic diagram.
Fig. 2 is the utility model Speed regulating rotary cultivator end view.
Speed governing gear-box, speed retaining travelling gear, power transmission shaft were realized in the middle of the utility model can be reequiped with existing rotovator, no-tillage drilling machine.
Figure 1 shows that hand drags supporting a kind of Speed regulating rotary cultivator, it has utilized no-tillage drilling machine, change former intermediate gear box into middle speed governing gear-box 1, the gear of retaining slowly 3 in the middle speed governing gear-box 1 does not have spline, drag the I reverse gear on chassis to be meshed with hand, when fast retaining of rotary ploughing cutter shaft and neutral, slowly keeping off gear 3 dallies with the I reverse gear, fast retaining gear 2 has keyway to slide on the spline axle head of power transmission shaft 5, setting retaining gear 2 to the right ahead when driving lever 4 is meshed with the chassis idler gear, rotary ploughing cutter shaft 8 quick rotation, it is neutral that 4 groups of driving levers keep off gear 2 disengaging chassis idler gears soon to the centre position, set the engaging tooth and the engaging tooth engagement that keeps off gear 3 sides slowly of retaining gear 2 sides when driving lever 4 left ahead, drive power transmission shaft and rotate rotary ploughing cutter shaft 8 slow rotation.To keep off the enlarged diameter that gear 2 keeps off gear 3 slowly soon, increase the centre-to-centre spacing between chassis driving wheel and Speed regulating rotary cultivator, large diameter anti-pulley is installed, simple in structure, can not produce wheel clogging during the water field ploughing operation, both flexible to operation, energy-efficient again.
Claims (3)
