Description

Technical Field

[0001] The utility model relates to the field of transplanting machines, in particular to a contouring component of a transplanting machine. Background Art

[0002] The profiling assembly controls the lifting and lowering of the transplanting device through the contact between the profiling wheel and the ground. Conventional profiling assemblies are fixedly connected to the connecting arm and the mounting base for mounting the profiling wheel. That is, as the ground rises and falls, the mounting base and the connecting arm swing synchronously with the profiling wheel, and the connecting rod swings in an arc shape within the arc groove.

[0003] However, when the profiling wheel contacts a compacted and high soil block during operation, the mounting seat and the connecting arm will move to the limit state, that is, the connecting rod moves to the rightmost side in the arc groove. Since the connecting arm and the mounting seat are in rigid contact, the connecting rod, the connecting arm or the mounting seat will be blocked by the soil block and deformed, resulting in damage to the profiling component.

[0004] In summary, how to avoid damage to the profiling component and smoothly pass the profiling wheel through the soil block has become an urgent problem that researchers in this field need to solve. Summary of the Invention

[0005] The technical problem to be solved by the utility model is: how to avoid damage to the profiling component and smoothly pass the profiling wheel through the soil block;

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] The utility model discloses a profiling component for a transplanter, which is used to control the lifting of a transplanting device in the transplanter, comprising: a mounting seat; a transition seat coupled to one end of the mounting seat, and having an arc groove on its side wall; a connecting arm, a hinged end in the middle of which is hinged to the transition seat, a mounting seat hinged at its bottom, and a connecting rod connected to its top free end located in the arc groove; a tension spring connecting the connecting rod and the transition seat; a profiling wheel rotatably arranged on the mounting seat; and a reset torsion spring arranged at the hinge of the mounting seat and the connecting arm; when the profiling wheel is subjected to force, the angle between the mounting seat and the connecting arm changes, and the reset torsion spring follows the twisting; when the profiling wheel unloads force, the reset torsion spring resets, driving the mounting seat and the connecting arm to an initial state;

[0008] In this solution, the connecting arm and the mounting base are connected by a hinge, and a reset torsion spring is installed at the hinge. The remaining settings are the same as those in the prior art and will not be elaborated in detail in this solution.

[0009] When the profiling component moves to the right, after the profiling wheel contacts the soil block, the connecting arm and the mounting seat move counterclockwise synchronously. At this time, the connecting rod moves to the rightmost side of the arc groove, and the connecting arm and the mounting seat are in the extreme position; when the profiling component continues to move to the right, the profiling wheel continues to contact the soil block, the position of the connecting arm does not change, the mounting seat moves counterclockwise relative to the bottom of the connecting arm, and the reset torsion spring is twisted; after the profiling wheel passes the soil block to the right, the reset torsion spring resets, drives the mounting seat to rotate clockwise, and puts the mounting seat and the connecting arm into the initial state; due to the addition of a hinge between the mounting seat and the connecting arm, damage to the profiling component is avoided, and the addition of a reset spring realizes the reset of the mounting seat after relative rotation, so that the profiling wheel can pass through the soil block smoothly.

[0010] To illustrate the specific structure of the mounting base, the mounting base adopted in the present invention comprises: a body, the top two sides of which are folded upward to form hinged ears, and the bottom two sides of which are folded downward to form connecting ears; wherein a contour wheel is connected between the two connecting ears;

[0011] In this solution, the top of the mounting seat is provided with two hinged ears for hinged connection with the connecting arm, and the bottom of the mounting seat is provided with two connecting ears for connecting with the contoured wheel.

[0012] In order to illustrate how the connecting arm is hinged to the mounting base, the present invention adopts a method in which a rotating shaft parallel to the axis of the contoured wheel is provided at the bottom of the connecting arm; the rotating shaft is connected to the two hinged ears; a return torsion spring is sleeved on the rotating shaft, one torsion arm of the return torsion spring abuts against the rear side of the connecting arm, and the other torsion arm abuts against the front side of the body;

[0013] The rotating shaft is connected to the hinged support ear and the bottom of the connecting arm. The rotating shaft provides an installation position for the reset torsion spring. The torque arm of the reset torsion spring is respectively against the rear side of the connecting arm and the front side of the body. When the mounting base rotates counterclockwise, the reset torsion spring can store energy.

[0014] In order to enable the mounting seat to rotate clockwise relative to the connecting arm under the action of the reset torsion spring, the utility model adopts a first limit block extending outward from the front end of the mounting seat; a second limit block extending outward from the front end bottom wall of the connecting arm; when the mounting seat and the connecting arm are in the initial state, the first limit block and the second limit block are in surface contact;

[0015] In this solution, when the mounting seat and the connecting arm are in the initial state, the first limit block and the second limit block limit the mounting seat from rotating clockwise relative to the connecting arm.

[0016] In order to prevent the torsion arm from being separated from the connecting arm, the present invention adopts a hook-shaped limiting section at the end of the torsion arm, and the limiting section extends forward along the inner side wall of the connecting arm.

[0017] The beneficial effects of the utility model are as follows: the utility model is a profiling component of a transplanter, when the profiling component moves to the right, after the profiling wheel contacts the soil block, the connecting arm and the mounting seat move counterclockwise synchronously, at this time the connecting rod is at the rightmost side of the arc groove, and the connecting arm and the mounting seat are in the extreme position; when the profiling component continues to move to the right, the profiling wheel continues to contact the soil block, the position of the connecting arm does not change, the mounting seat moves counterclockwise relative to the bottom of the connecting arm, and the reset torsion spring is twisted; after the profiling wheel passes the soil block to the right, the reset torsion spring is reset, driving the mounting seat to rotate clockwise, and putting the mounting seat and the connecting arm into the initial state; due to the addition of a hinge between the mounting seat and the connecting arm, damage to the profiling component is avoided, and the addition of the reset spring realizes the reset of the mounting seat after relative rotation, so that the profiling wheel can pass through the soil block smoothly.
