Abstract
The utility model relates to a self-sharpening knife for straw-crushing-and-returning-to-field machines and rotary cultivators, which is designed in respect to the shortcomings associated with prior knife and based on the principle that the force-applied area of a knife for a farm implement is proportional to the load of the implement. The utility model is an improvement based on prior knifes for straw-crushing-and-returning-to-field machines and rotary cultivators. The main improvement is that a layer of carbon alloy is arranged at middle lower part of the knife body of prior knife. The utility model has the advantages of the good self-sharpening effect, the rapid operation speed, the good operation quality, the long service life and the low energy consumption.
Description
Technical field
The utility model relates to a kind of straw crushing and field-returning machine, rotovator self-sharpening formula cutter, belongs to the agricultural machinery annex.
Background technology
At present, stalk crushing and returning machine knife commonly used has two kinds, and a kind of is hilted broadsword body formula cutter (as Figure 1-3), and another kind is a double-pole body formula cutter (shown in Fig. 4,5); Rotovator cutter commonly used is shown in Fig. 6,7.The shortcoming of above-mentioned cutter is all can not reach the self-sharpening effect, and in the farm work process, cutter life is short, and operation quality is poor, and the farm machinery working load is big, and serious to farm machinery damage itself, operation quality and operating efficiency all can not reach ideal effect.With 50 horsepowers of tractor operations is example, and oil consumption at present is 2.5 liters/mu, and a secondary cutter is energy 250-350 mu of ground of operation (reaching the general job standard) generally, and the frequent excess load farm work of farm machinery, so agricultural machinery farm work cost is big, charge is high, and the peasant economy burden is heavy.
Summary of the invention
Technical problem to be solved in the utility model provide a kind ofly have that good self-sharpening effect, operating speed are fast, operation quality good, long service life, straw crushing and field-returning machine, rotovator self-sharpening formula cutter that energy consumption is low.
The technical scheme that its technical problem that solves the utility model adopts:
The utility model is at present cutter existing shortcoming in operation, puts forth effort according to the farm implements cutter that principle that area is directly proportional with the size of agricultural machinery load designs.
The utility model is to improve to form on the basis of existing stalk crushing and returning machine, rotovator cutter, and its main improvement is to be provided with one deck carbon alloy layer in the middle and lower part of the cutter hub of former cutter.
The beneficial effects of the utility model are as follows:
1, cutter can produce the self-sharpening effect when farm work, and operating speed is fast, and operation quality is good.
2, the farm machinery working load is little, and cutter is little to the impulsive force of farm machinery with the resistance that changes when operation, so can prolong the service life of farm machinery.With 50 horsepowers of tractors is example, uses cutter can alleviate the agricultural machinery load more than 10 horsepowers, and oil consumption is reduced to 2 liters/mu by 2.5 liters/mu, and oil consumption reduces by 20%, and particularly when cutter work was more than 100 mu, the self-sharpening effect was more obvious.
3, the cutter work capacity is brought up to 400-500 mu by the 250-350 mu before improving.
4, during the stalk crushing and returning machine operation and since cutter when running into barrier resistance little, so can further reduce stubble height.
5, because cutter is sharp, so straw is pulverized length qualification rate height.
6, in the operation process, airborne dust, broken blade obviously reduce, thereby have improved agricultural machinery and tractor driver's operating environment around the farm machinery.
