Abstract
The utility model relates to a rotary tiller suitable for deep rotary tillage in narrow range. The rotary tiller comprises an upper hanging device, a reduction gearbox, a side plate, a transmission device, a protective cover, a trailing bar, a rotary blade, a cutter shaft and a stand. On the basis of increasing the diameter of the cutter shaft, the length of the rotary blade is reduced to increase the depth of rotary tillage, so that the force applied to the rotary blade is reduced, the side chain is adopted for transmission, the soil is continuously cut by using the rotary blade rotated at high speed, therefore, the utility model is the novel rotary tiller with more than 30 cm depth of rotary tillage.
Description
Affiliated technical field
The utility model relates to a kind of rotovator in the agricultural machinery
Background technology
Rotovator is a kind of tillage implement commonly used, has the operation effectiveness of plow harrow unification, and rotary tillage once can reach the effect of native broken Horizon, and can effectively cut off vegetation and it is mixed in the plow layer.Chemical fertilizer, agricultural chemicals etc. are mixed in soil, are one of the main matched farm tools on the whole ground of mechanization.
The area is still continued to use traditional tillage method and is carried out agricultural production on the dam, Hebei, soil exposes, wind erosion is violent, organic and moisture runs and loses seriously, soil depletion and Ecological environment worsening have been aggravated, seriously restricted the further raising of China's grain yield, taked the banded methods of cultivation of revolving deeply to be necessary at this regional situation.Use the ability that this kind method can strengthen the soil water storage soil moisture conservation, fully admit natural rainfall, improve the availability of limited precipitation, alleviate the restriction of shortage of water resources agricultural production; Can reduce disturbance on the other hand to the arable land topsoil; help preventing that seasonal strong wind weather is to soil degradation; preserve the ecological environment, for promoting the local grain-production positive meaning that reaches a new stage, and will produce ten minutes considerable economic and social benefit.
Present stage, domestic for the also not research of band shape deep ploughing technology, the general rotary tillage degree of depth of the rotovator that China develops can not satisfy the requirement of area plantation root vegetables crop on the dam.Therefore, at the situation in area on the present dam, develop the special small-sized rotovator that revolves deeply and be necessary.
Summary of the invention
The utility model provides a kind of small-sized rotovator that revolves deeply in a narrow margin that is applicable to.This machine adopts side chain drive, mainly increase and select the tilling depth degree by increasing cutter shaft diameter, its cutter shaft radius is greater than rotary blade length, the rotary blade excurvation at two ends, the point of a knife width of outermost two rotary blades is greater than the cutter shaft width, to reduce the rotational resistance of cutter shaft in soil, tilling depth can reach more than the 30cm, tilling width is 50cm, make rotovator tilling depth scope widen significantly, the increasing rate of power consumption is less, can improve the deep subsoil gas permeability, increase moisture holding capacity, and satisfy the agriculture requirement of cultivation potato class, the deep ploughing of root vegetables crop needs.
The beneficial effects of the utility model are: owing to increase the method for tilling depth is to strengthen the cutter shaft diameter, reduced rotary blade length, and then it is stressed to have reduced cutter, and power consumption is less.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a vertical view of the present utility model.
Hang on 1. among the figure, 2. reduction box, 3. right plate, 4. transmission device, 5. guard shield, 6. trailing bar 7. revolves cutter, 8. cutter shaft, 9. frame.
Embodiment
In the accompanying drawings this rotovator by last suspension (1), reduction box (2), right plate (3), transmission device (4), guard shield (5), trailing bar (6), revolve cutter (7), cutter shaft (8), frame (9) and form.Reduction box is equipped with travelling gear in (2), the power that is spread out of by reduction box (2) passes through side driving-chain device (4), drive cutter shaft (8) work, drive then and revolve cutter (7) and rotate together, cutting soil and with the soil block throwing backward of downcutting, clash into mutually with the guard shield (5) that is fixed on cutter shaft (8) top and the trailing bar (6) at rear, the further fragmentation of soil block is fallen earthward, play the effect that increases hack and level land.Owing to increase the method for tilling depth is to strengthen the cutter shaft diameter, reduced rotary blade length, and then it is stressed to have reduced cutter.
Claims (2)
1, a kind of rotovator that revolves deeply in a narrow margin that is applicable to, by last suspension, reduction box, side plate, transmission device, guard shield, trailing bar, revolve cutter, cutter shaft and frame and form, it is characterized in that: increase tilling depth by strengthening the cutter shaft diameter, its cutter shaft radius is greater than rotary blade length.
2, rotovator according to claim 1 is characterized in that: the rotary blade excurvation at two ends, the point of a knife width of outermost two rotary blades is greater than the cutter shaft width.
