Detailed Description
All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
Referring to fig. 1-4, the present invention provides the following technical solutions: the utility model provides a rotary blade with prevent rupture, prevent twining careless, the efficient rotary blade that digs, includes rotary blade handle of a knife 1, the upper portion of rotary blade handle of a knife 1 is provided with fixed orifices 2, the below of rotary blade handle of a knife 1 is provided with rotary tillage portion 3, still be provided with between rotary tillage portion 3 and the rotary blade handle of a knife 1 and prevent twining careless device 4, rotary tillage portion 3 includes cutting part 301, income place 302, expand and revolve portion 303, the end that expands and revolve portion 303 still is provided with soil turning structure 304.
Example 2
The included angle between the rotary blade handle 1 and the cutting part 301 is 150 degrees.
Example 3
The included angle between the rotary blade handle 1 and the cutting part 301 is 120 degrees.
Example 4
The included angle between the rotary blade handle 1 and the cutting part 301 is 180 degrees.
According to the Pythagorean theorem, because the rotary tillage depth is fixed, the relative length of the rotary tillage blades is fixed, the smaller the included angle is, the longer the other side is, namely the length of the cutter handle and the cutting part, when the included angle is selected to be 120 degrees, the cost increase caused by the increased length is higher, and the potential safety hazard caused by the size increase is increased;
meanwhile, the larger the included angle is, as shown in fig. 6, the relative thickness is reduced, and the safety of the rotary blade is reduced under the condition of the same thickness.
Therefore, preferably, the included angle between the rotary blade handle 1 and the cutting part 301 is 150 °, which can achieve the optimized ratio: the cutter has the advantages of being suitable in overall length and thickness, reducing the purchase cost of the cutter, prolonging the service life and reducing potential safety hazards.
Example 5
Between cutting portion 301 and the portion 303 of rotating that expands, vertical direction is 150 contained angles.
Example 6
An included angle of 180 degrees is formed between the cutting part 301 and the rotating expanding part 303 in the vertical direction,
as can be known from FIG. 6, the vertical direction between the cutting part 301 and the expanding rotary part 303 is an included angle of 150 degrees, so that the stress condition of the rotary blade is more uniform, the blade breaking condition is less likely to occur, the service life is prolonged, and the potential safety hazard is reduced.
Example 7
The soil turning structure 304 is a propeller blade structure, and the structural attack angle is 5 degrees.
Example 8
The soil turning structure 304 is a propeller blade structure, and the structural attack angle is 10 degrees.
Example 9
The soil turning structure 304 is a propeller blade structure, and the structural attack angle is 13 degrees.
When the attack angle of the soil turning structure 304 is 5 degrees, the resistance from the soil is small, but the effect of turning the soil upwards is correspondingly reduced; when the attack angle of the soil turning structure 304 is 10 degrees, the resistance from the soil is large, the effect of turning the soil upwards is correspondingly good, but after the soil is used for 24 hours, the rotary tillage cutter is not obviously deformed; when the attack angle of the turning structure 304 is 13 degrees, the resistance from the soil is the largest, but the soil turning effect is the best correspondingly at the same time, however, after the rotary blade structure is used for more than 24 hours, the deformation condition occurs, so that the attack angle of the turning structure is the best 10 degrees.
Preferably, the longitudinal sections of the cutting part 301 and the rotation expanding part 303 are steel castings with arc-shaped cutting-in angles, so that a better cutting-in effect can be provided, and the overall strength of the cutter body is not affected.
Preferably, prevent twining careless device 4 including round pin axle 401, steel ring 402, round pin axle 401 includes fixed part 4011, activity post 4012, spring 4013, still be provided with stopper 4014 on the activity post 4012, prevent twining careless device 4 rear portion and correspond the position of rotary blade handle of a knife 1 and be provided with the strengthening rib, such setting, when taking place to twine the grass condition, the rotary blade is at rotatory in-process, and the grass can take place to remove because the atress at both ends is different, so, steel ring 402 will produce the rotation to better and more quick messenger's grass drops, reaches the effect of preventing twining the grass, and because steel ring 402, round pin axle 401 often rotate, damages easily, so set up detachable construction, conveniently change.
The working principle and the using process of the invention are as follows: when using, at first through the fixed orifices 2 that set up with the fixed fastening of rotary blade, dig through the structure of digging, because it is screw paddle structure, it digs more evenly, through preventing twining the rotatable steel ring of grass device, has reached the effect that is difficult for twining the grass, through the cutting part that sets up, expand the better angle of revolving the portion, has reached the purpose that improves the security, has reached cost control's purpose simultaneously.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
