Further, the knife handle is continuously bent to connect the knife handle and the knife body.

Further, the handle of a knife includes first kink and second kink, first kink is buckled dorsad the blade, the second kink is buckled towards the blade, the one end and the handle of a knife of first kink are connected, the other end with be connected of the one end of second kink, the other end and the blade of second kink are connected.

Further, the first bending part and the second bending part are connected smoothly.

Further, the rounded angle of the first bending part is 120-160 degrees.

Further, the rounded angle of the second bending part is 120-160 degrees.

Furthermore, the knife handle, the knife neck and the knife body are integrally formed.

The utility model discloses a rotary blade, the blade through with rotary blade sets up the both sides at the handle of a knife axis to when specifically setting up, set up the blade and link to each other with the sword neck one side to the width of the widest department of the opposite side of blade along the axis symmetric distribution of handle of a knife, after the shape of adjustment blade like this, can install the rotary blade handle of a knife distance that is closer apart from the rotary cultivator outer wall, just can guarantee the normal work of rotary cultivator, can make rotary blade can effectively work the overall dimension of rotary cultivator at the during operation, effectively reduce the soil and leak and plough. Moreover, after the rotary tillage cutter in the prior art is arranged on a rotary cultivator, a single cutter is arranged on the outermost side, and the single cutter is high in abrasion speed during tillage. The utility model provides a rotary blade, the installation back outside is two cutters, and two cutters cooperate the operation each other in turn during ploughing, and wearing and tearing obviously slow down, have reduced the time of changing the cutter, have improved work efficiency.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

In order to the above situation, the utility model provides a rotary blade, its concrete structure is as shown in fig. 3, including integrated into one piece handle of a knife 1, sword neck 2 and blade 3, wherein handle of a knife 1 and blade 3 link to each other through sword neck 2, as shown in fig. 3, one side of blade 3 links to each other with sword neck 2, and the top of opposite side is knife tip 4, from one side that blade 3 links to each other with sword neck 2 to the opposite side of blade 3 (the one side at knife tip 4 place), the width of the widest department, this width is along the axis symmetric distribution of handle of a knife 1, and this width only is the width of blade 3, does not include the width of handle of a knife 1.

In the above embodiment, the blade 3 of the rotary blade is arranged on two sides of the axis of the handle 1, and when the rotary blade is specifically arranged, the width from one side of the blade 3 connected with the blade neck 2 to the widest part of the other side of the blade 3 is symmetrically distributed along the axis of the handle 1, so that after the shape of the blade 3 is adjusted, the schematic view of the installation structure of the rotary blade is shown in fig. 4, the handle of the rotary blade can be installed at a distance closer to the outer wall of the rotary cultivator, such as 35mm shown in fig. 4, the normal work of the rotary cultivator can be ensured, the rotary blade can effectively work to the overall dimension of the rotary cultivator during the work, and the missing of the soil can be effectively reduced. In addition, after the rotary tillage cutter in the prior art is installed on a rotary cultivator, a single cutter is arranged on the outermost side, and as shown in figure 2, the single cutter is quickly abraded during tillage. The outmost side of the rotary blade in the embodiment is provided with two cutters, the two cutters are alternately matched with each other during tillage, abrasion is obviously slowed down, cutter replacement time is shortened, and working efficiency is improved.
