Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and the following embodiments are used to illustrate the present invention.

As shown in fig. 1 to 5, a rotary tillage planter comprises a rotary tillage roller 1 and rotary tillage blades 2 arranged on the rotary tillage roller 1, wherein a plurality of tool holders 3 are uniformly connected on the rotary tillage roller 1, one end of each tool holder 3 is provided with a connecting block 4, the end part of each connecting block 4 is elastically and rotatably connected with the rotary tillage blades 2, the rotary tillage blades 2 and the connecting blocks are elastically connected, so that when a large resistance is applied, the elastic structure can be compressed, the rotary tillage blades 2 rotate on the end surfaces of the connecting blocks 4, a certain degree of evasion can be performed, the risk of breakage can be avoided, the length direction of each connecting block 4 is not parallel to the axis of the tool holder 3, namely, the end surfaces of the connecting blocks 4 are not parallel to the end surfaces of the rotary tillage roller 1, so that the rotary tillage blades 2 can rotate to generate the axial position of the rotary tillage roller 1 when being pushed, and a large rotation amount cannot be set due to the elastic rotation on the rotary tillage blades 2, therefore, the rotary cultivator can only avoid less parts, the part can be prevented from being limited by the movement in the axial direction, the passing rate of the rotary cultivator is improved, the forced cultivation is avoided, the breakage is avoided, the axes of the tool holder 3 are parallel to the end face of the rotary cultivating roller 1, the included angle between the tangent line of the intersection point of the axes of the tool holder 3 and the rotary cultivating roller 1 and the axis of the tool holder 3 is smaller than 30 degrees, the larger the angle is, the longer the force arm is when the rotary cultivating blade 2 is in contact with the ground to generate acting force, the larger the generated torque is, the bending of the tool holder 3 is easy to cause, the smaller the angle is, and the smaller the force arm is, so that the possibility that the tool holder 3 is damaged is further reduced.

The cutter handles 3 are distributed in the rotary tillage roller 1 in an axial staggered manner, the staggered manner means that the position of the cutter handle 3 on each row arranged along the axial direction is different from the position of any one cutter handle 3 on the adjacent row in the axial direction, so that the staggered manner aims to improve the coverage surface, and because the cutter handles 3 on the same row along the axial direction are certainly spaced, an uncovered area exists during rotary tillage due to the spacing, and the staggered manner of other rows can cover the whole body in an alternate distribution manner, so that the leakage area is avoided.

Every connecting block 4 on the handle of a knife 3 all is equipped with two sets ofly, and both fixed connection and become V type structural distribution, and two sets of main effects that are the V type are more balanced, because only set up the bending that the yawing force that then produces probably leads to handle of a knife 3 under long-term effect, and to a certain direction, also do not benefit to the normal rotation of rotary tillage roller 1 itself simultaneously, two sets of more elastic rotation is connected between connecting block 4 and the handle of a knife 3, and elastic rotation is convenient for further improvement rotary blade 2 at 1 ascending displacement width of rotary tillage roller axial to improve its possibility of dodging, elasticity then makes things convenient for its to reset, can adopt elastic construction such as torsional spring.

The top of the rotary blade 2 is connected with an adapter rod 5, the adapter rod 5 is rotatably connected with a connecting block 4, the adapter rod 5 is connected with a limiting block 6, an elastic part 7 is arranged between the end part of the rotary blade 2 and the connecting block 4, a mounting groove with a diameter larger than that of the adapter rod 5 is arranged on the connecting block 4, a stop block which is the same as that of the limiting block 6 is arranged in the mounting groove, both the two are arc blocks, a certain included angle is formed between the two blocks on the circumference, the included angle area is the rotating space of the adapter rod 5, the two blocks are limited when being contacted, so that the adapter rod 5 is not rotated, the elastic part 7 is preferably a nitrogen cylinder, because the nitrogen cylinder is different from a spring, the nitrogen cylinder has certain initial force, the nitrogen cylinder cannot be compressed when the initial force is not reached, the spring can also be used, but can be compressed as long as the spring is stressed, so that the nitrogen cylinder is relatively more favorable for use, the power that receives when not meetting stone or root system all is the land effort, generally can not be very big, and the stone is because in whole bathroom soil, the root system then because its side is complicated leads to being difficult to dig up, consequently can not lead to the rotation of rotary blade 2 in the normal action, then compression rotation when meeting stone or root system, makes rotary blade 2 rotate and axial displacement avoids the rigidity contact to break.
