Description

A kind of rotovator

The utility model belongs to a kind of rotovator, is particularly suitable for mountain area, hills, terraced fields, the farmland rotary tillage operation of narrow plot, gorge.

At present, be used for farming operation and mostly adopt two-wheeled, three-wheel, four-wheel rotovator, these rotovators are because wheel is many, the transformation angle is big, very flexible, so only use in the farming of the field of flat area, and, be difficult to grasp balance to those mountain areas, hills and uneven farming operation, the difficulty that operates is big, especially rotary tillage can not be carried out in the farmland less to line-spacing, that crop is higher, and its power set mostly adopt diesel engine, so the scope of application is little.

The purpose of this utility model provides a kind of easy and simple to handle, and flexibility is strong, the rotovator of wide accommodation.

The technical solution of the utility model is: include frame, power set are housed on frame, one side of frame is equipped with gearbox, it is characterized in that also being fixedly connected with on the frame handrail, be equipped with below the frame by the walk alone wheel of power set by actuator drives, output shaft at the wheel of walking alone is connected with rotary cultivator attachment by chain, and rotary cultivator attachment is fixedly connected on the frame by lifting support.

Compare with existing like product, the utility model has adopted a road wheel, grasps balance easily, makes walking convenient, and flexibility is strong; Power section of the present utility model also can be changed the use electromotor as required, thereby reduces environmental pollution, has enlarged the range of application of rotovator.

, be further described the utility model below in conjunction with drawings and Examples.

Fig. 1 is the overall structure schematic diagram that the utility model uses engine;

Fig. 2 is the right view of Fig. 1;

Fig. 3 is the overall structure schematic diagram that the utility model uses electromotor.

Fig. 1 and Fig. 2 illustrate first embodiment that the utility model uses diesel engine.The utility model is equipped with diesel engine on frame 20, a side of frame 20 is equipped with gearbox 18, passes through handrail height adjusting device 5 fixedly connected handrails 9 on frame 20.Arrangement for adjusting height 5 is divided into high, medium and low third gear to be regulated, to adapt to the different work requirement for height.Be equipped with below frame 20 by the walk alone wheel 19 of diesel engine 1 by actuator drives, this wheel of walking alone can use rubber wheel, iron tyre or wooden the wheel.Output shaft 16 at the wheel 19 of walking alone is connected with rotary cultivator attachment 11 by chain 14, and rotary cultivator attachment 11 is fixedly connected on the frame 20 by lifting support 10, and also replaceable as required rotary cultivator attachment is installed single plow, carries out cultivation operation; Trench digging ridging device is installed is carried out field trench digging ridging operation.Above-mentioned described transmission device is by being installed in drive 2 on the diesel engine output shaft, drive 2 takes turns 19 through main clutch 3 by walking alone on the 7 control gear gearboxes of the main clutch control crank on the handrail 9,18 output shafts, on wheel 19 1 sides of walking alone are coaxial auxilliary clutch 15 is housed, auxilliary clutch 15 is by the auxilliary clutch control handle 6 control rotary cultivator attachments 11 that are installed on the handrail 9.Rotary cultivator attachment 11 is equally distributed rotary blades 12 in the rotating shaft of gear 13, and the rotary blade guard shield 21 above rotary blade 12 is formed.

During the rotary tillage operation, at first the lifting handle 4 that will be connected with lifting support 10 puts down, lifting support 10 is being with rotary cultivator attachment 11 to fall simultaneously, the power of engine 1 is through drive 2, main clutch 3 gear 17 on speed-changing gear box 18, the gear 13 that chain 14 transfers on the rotary cultivator attachment 11 is rotated, finish the rotary tillage operation by rotary blade 12, the wheel 19 of walking alone that install on gearbox 18 output shafts this moment is walked.The walking of road wheel 19 is finished with the main clutch control crank 7 manipulation main clutchs 3 that stop by being installed on the handrail.It is to be finished by the auxilliary clutch 15 of auxilliary clutch control handle 6 manipulations that is installed on the handrail 9 that rotary cultivator attachment 11 stops with rotation, and when stopping operation, operation lifting handle 4 is mentioned rotary cultivator attachment 11 with lifting support 10.The speed control of engine is to be finished by the speed control handle 8 that is installed in above the handrail 9.

Fig. 3 is that the utility model uses electromotor second embodiment, with the difference that diesel engine is installed be to be replaced by electronic joystick 8 at speed control handle 8 places, engine is changed to electromotor.Between joystick 8 and electromotor, installed electric control box 22 additional.The work of its electromotor is that joystick 8 is realized by electric control box 22, and other structure is identical with the course of work.

Second embodiment is having under the situation of electric power and could realize, the crop in for example big grid etc. do not have environmental pollution.
