Abstract
The invention discloses agricultural machinery and a production method thereof, and in particular relates to an abrasion-resisting rotary blade and the production method thereof. The production method of the energy-saving type abrasion-resisting rotary blade comprises the following processes: tungsten carbide is welded on the surface of a base material by carbon dioxide gas arc welding; the whole of the welded base material is heated up to 1000-1100 DEG C and then is processed by the operation of rolling moulding to obtain the rotary blade. As an abrasion-resisting layer is rolled on the working face of the rotary blade, the service life of the rotary blade is prolonged; according to a large quantity of experiments, the service life of the rotary blade is equal to the service life of 3-5 rotary blades; and therefore, the waste of energy is greatly lowered, and meanwhile the use cost of peasants is lowered.
Description
Technical field
The present invention relates to a kind of farm machinery and production method thereof, particularly relate to a kind of wear-resistant rotary tillage knife and production method thereof.
Background technology
Rotovator is that agricultural goes up the machinery that loosens the soil commonly used, because the use of rotovator makes efficient, the quality in rotary tillage soil obtain significantly improving, also greatly reduces peasant's labour intensity simultaneously, has reduced the cost of peasant's rotary tillage.Rotary blade is a kind of hack instrument on the rotovator, is the important component part of rotovator.The blade of rotary blade is soil body milling, and the soil body that cuts down is thrown the rear, and the soil body is smashed.The stressed comparatively complexity of rotary blade both had been subjected to powerful impact, also was subjected to the wearing and tearing of soil simultaneously; It is made up of handle of a knife, blade, bending segment and cutter head.Because it is sex-limited that the rotovator farming is subjected to the restriction in season to cause its use to have when certain, this service life that just requires rotary blade, the longer the better, prolongs the time of changing as far as possible.
The rotary blade that generally uses mostly is to adopt the metal material casting to form at present, and rotary blade is in the working time, and working face often is worn, other part is all intact, and the working face place is serious wear then, causes whole rotary blade discarded, waste energy, also increased peasant's use cost simultaneously.
Summary of the invention
The present invention provides a kind of energy-saving type wear-resistant rotary tillage knife and production method thereof, purpose exactly in order to solve the problems of the technologies described above be the service life that prolongs rotary blade, reduces energy waste, and then reach purpose of energy saving.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions.
A kind of energy-saving type wear-resistant rotary tillage knife, it is made up of handle of a knife, blade, bending segment and cutter head, wherein is provided with wearing layer on the working face of rotary blade.
Described wearing layer is arranged on rotary blade and the ground position contacting.
Described wearing layer is arranged on blade, bending segment and the cutter head.
Described wearing layer is arranged on the position of cutter head to the 1/3-2/3 blade.
The width of the wearing layer at described blade place is a 1/4-4/5 blade width, and the width of the wearing layer of bending segment is a 1/4-4/5 bending segment width, and cutter head all is provided with wearing layer.
Described blade, bending segment place wearing layer are arranged on apart from blade 0.5-2mm place.
The thickness of described wearing layer is 0.2-1mm.
A kind of production method of energy-saving type wear-resistant rotary tillage knife is got base material, adopt carbon dioxide gas arc welding that tungsten carbide is welded on the surface of base material then, will weld good base material integral body again and be heated to 1000-1100 degree centigrade and both carried out roll-forming then.
Advantage of the present invention and effect are as follows:
The present invention since on the working face of rotary blade roll-in wearing layer, prolonged the service life of rotary blade, can be equivalent in the past through lot of experiment validation the present invention one that 3-5 greatly reduces the waste of the energy to the service life of rotary blade to rotary blade, also reduce peasant's use cost simultaneously.Diesel oil 15-30 liter can be saved in 100 mu of soils of the every rotary tillage of peasant.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure, 1, handle of a knife; 2, blade; 3, bending segment; 4, cutter head; 5, blade; 6, wearing layer.
Embodiment
Below description by embodiment the present invention is described in further detail, but this can not be used for limitation of the present invention, those skilled in the art are according to basic thought of the present invention, can make various modifications or improvement, but only otherwise break away from basic thought of the present invention, all within the scope of the present invention.
As shown in Figure 1, energy-saving type wear-resistant rotary tillage knife structure of the present invention is as follows: it is made up of handle of a knife 1, blade 2, bending segment 3 and cutter head 4, and wearing layer 6 is set on the working face of whole rotary tillage cutter hub; Also wearing layer 6 can be arranged on rotary tillage cutter hub and the ground position contacting in order to reduce production costs; Or wearing layer 6 is arranged on blade 2, bending segment 3 and the cutter head 4.
The optimum position that above-mentioned wearing layer 6 is provided be at cutter head to the scope of the 1/3-2/3 of blade.
The width of the wearing layer 6 at blade 2 places is a 1/4-4/5 blade width, and the width of the wearing layer 6 of bending segment 3 is the width of 1/4-4/5 bending segment 3, and cutter head 4 all is provided with wearing layer 6.Blade 2, bending segment 3 place's wearing layers 6 are arranged on apart from blade 50.5-2mm position.The thickness of wearing layer 6 is 0.2-1mm.
A kind of production method of energy-saving type wear-resistant rotary tillage knife: get base material, base material can be any materials of 65 manganese or other production rotary blade, and this step is a conventional method, is not described in detail; Adopt carbon dioxide gas arc welding tungsten carbide to be welded on the surface of base material then; To weld good base material integral body again is heated to 1000-1100 degree centigrade and has both carried out roll-forming then.
