Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of rotary blade, particularly a kind of loosenning tiller rotary blade.
Background technology
Loosenning tiller is more and more used in agricultural production in recent years.The main working parts of loosenning tiller is rotary blade, rotary blade by the rotation and forward travel directly to the farmland rotary tillage process, the concrete course of work comprises rotary blade rotation, the cutting of burying, throwing soil and advances, when rotary blade acted on soil, soil equally also reacted on the rotary blade blade.Rotary blade generally comprises rotating shaft, the base that is connected with rotating shaft and blade, described blade comprises operate portions and installation portion, installation portion is connected on base, current blade generally is arranged on a side of base, like this in the situation that soil hardness is higher or soil in be mingled with the hard thing such as masonry, the suffered resistance of blade is larger, can cause the base gross distortion, thereby affect rotary blade service life.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of suffered resistance little, the loosenning tiller rotary blade of long service life.
the purpose of this utility model can realize by following technical proposal: a kind of loosenning tiller rotary blade, comprise rotating shaft, the base that is connected with rotating shaft and blade, it is characterized in that, comprise two the first blades that be arranged in parallel and two the second blades that be arranged in parallel, the first blade and the second blade form by installation portion and operate portions, described the first blade and the second blade circumferential hoop on base and the angle between adjacent two blades be 90 °, described the first blade is arranged on the base upper surface, described the second blade is arranged on the base lower surface, the first blade work section bending direction is opposite with the second blade work section bending direction.
Two the first blades and two the second blades are arranged on respectively the both sides of base, can reduce the single side of base stressed, slow down the base distortion, have extended service life.
In above-mentioned a kind of loosenning tiller rotary blade, described two the first blade work section bending directions are towards the base lower surface, and described two the second blade work section bending directions are towards the base upper surface.
In above-mentioned a kind of loosenning tiller rotary blade, it is 160 ° that described first blade work section's angle of bend and the second blade work section angle of bend are.Choose reasonable point of a knife angle of penetration can reduce the suffered resistance of blade, has reduced the wear rate of rotary blade blade, extends rotary blade service life.
In above-mentioned a kind of loosenning tiller rotary blade, described installation portion is connected on base by bolt, and described operate portions has the camber breach near rotating shaft one side.
In above-mentioned a kind of loosenning tiller rotary blade, described rotating shaft is connected on base by welding.Solid and reliable.
Compared with prior art, the advantage of this loosenning tiller rotary blade is: 1, two the first blades and two the second blades are arranged on respectively the both sides of base, can reduce the single side of base stressed; 2, change the blade bending angle and make the blade angle of penetration reach an optimum state, be subject to resistance force diminishes during work, reduced the wear rate of rotary blade blade, increase the service life.
Description of drawings
Fig. 1 is the structural representation that the utility model provides.
In figure, 1, rotating shaft; 2, base; 3, the first blade; 3a, installation portion; The 3b operate portions; 4, the second blade.
Embodiment
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
Loosenning tiller rotary blade as shown in Figure 1 comprises rotating shaft 1, the base 2 and the blade that are connected with rotating shaft 1, and rotating shaft 1 is connected on base 2 by welding, and is solid and reliable.Blade comprises again two the first blades 3 that be arranged in parallel and two the second blades 4 that be arranged in parallel, the first blade 3 and the second blade 4 form by installation portion 3a and operate portions 3b, the first blade 3 and the second blade 4 circumferential hoops on base and the angle between adjacent two blades be 90 °, installation portion 3a is connected on base 2 by bolt, and operate portions 3b has the camber breach near rotating shaft 1 one sides.
The first blade 3 is arranged on base 2 upper surfaces, and the second blade 4 is arranged on base 2 lower surfaces, and two the first blades 3 and two the second blades 4 are arranged on respectively the both sides of base 2, can reduce the single side of base 2 stressed, slow down base 2 distortion, increase the service life.The operate portions 3b bending direction of the first blade 3 is opposite with the operate portions 3b bending direction of the second blade 4, be specially the operate portions 3b bending direction of two the first blades 3 towards base 2 lower surfaces, the operate portions 3b bending direction of described two the second blades 4 is towards base 2 upper surfaces.It is 160 ° that the operate portions 3b angle of bend of the operate portions 3b angle of bend of the first blade 3 and the second blade 4 is.Choose reasonable point of a knife angle of penetration can reduce the suffered resistance of blade, has reduced the wear rate of rotary blade blade, extends rotary blade service life.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
