Technical Field

The invention relates to a transplanter, in particular to an improvement on the structure of a novel transplanting mechanism and the like of the transplanter.

Background

A rice transplanter is an agricultural machine for planting rice seedlings into rice fields. When planting, firstly, a mechanical claw takes out a plurality of rice seedlings from a seedbed and plants the soil in a field, and in order to keep the angle between the seedbed and the ground at a right angle, the front end of the mechanical claw must adopt an elliptic action curve when moving. The motion is completed by a planetary mechanism of a rotary or deformation gear, and the advancing engine can drive the motion machines at the same time. The rice transplanter must have anti-slip wheels and a floating design when moving on the soil. If the seedlings are cut into pieces, the rice seedlings are taken out from a specific seedling box and then planted in a mechanical mode.

The transplanting mechanism is taken as an important part of the transplanter and plays an indispensable important role, for example, Chinese patent with application publication number CN102342205A discloses a transplanting mechanism of the transplanter, which comprises a transplanting box, a rotary box and transplanting claws, and is characterized in that the transplanting box is arranged on a frame of the transplanter, a power output shaft of the transplanting box is connected with the rotary box, a sun wheel is arranged in the rotary box, the sun wheel is coaxial with the power output shaft of the transplanting box, the sun wheel is matched with first planet wheels arranged at two sides of the sun wheel, a second planet wheel is arranged at the outer side of each first planet wheel, the first planet wheel and the second planet wheel are eccentric wheels, a wheel shaft of the second planet wheel is connected with claw arms of the transplanting claws, the tail ends of the transplanting claws are provided with outer claw heads, the outer claw heads comprise two claw fingers, the claw arms are provided with inner claws and inner claws which are connected with the claw arms in a sliding way, and an elastic restoring mechanism which enables the inner claw to move upwards is arranged, the claw head of the inner claw is a single claw finger, the root part of the inner claw finger is arranged between two claw fingers of the outer claw, the upper end of the inner claw is rotationally connected with a driving rod, and the driving rod is rotationally connected with a claw arm and matched with a cam arranged on a wheel shaft of the second planet wheel.

However, the technical scheme has a complex structure and high cost, and the rotary box is easy to break down due to foreign matters when rotating.

Disclosure of Invention

The invention mainly solves the technical problems of complex structure, high cost, easy failure and the like in the prior art, and provides a novel transplanting mechanism of a transplanter, which can realize quick seedling taking and transplanting, stable rotation, simple structure and difficult failure.

In order to solve the technical problems and achieve the purpose, the invention provides a novel transplanting mechanism of a rice transplanter, which comprises a transplanting box and a transplanting claw, and is characterized in that the transplanting box is connected with the transplanting claw through a crank rocker mechanism, the crank rocker mechanism comprises a crank which is in driving connection with the rotation center of the transplanting box and rotates at a constant speed, a rocker which is hinged with the transplanting box and swings back and forth at a variable speed, the crank and the rocker are connected with the transplanting box, the other end of the crank and the other end of the rocker are hinged with a connecting rod which does planar compound motion, the crank connecting rod mechanism comprises a second connecting rod which is a crank, the rocker and a difference box at the connecting end of the crank and the rocker, so as to form a four-connecting rod mechanism, and the transplanting claw is fixedly connected with the connecting rod.

As an improvement of the novel transplanting mechanism of the rice transplanter, a rocker arm is fixedly connected to one side of the transplanting box, and the rocker is hinged with the rocker arm.

As an improvement of the novel transplanting mechanism of the transplanter, the transplanting claw is fixedly connected with the long connecting rod through a transplanting arm.

As an improvement of the novel transplanting mechanism of the rice transplanter, the short connecting rod and the crank are hinged and connected with the long connecting rod through a bearing.

As an improvement of the novel transplanting mechanism of the transplanter, the transplanting claw is arranged on one side of the crank.

As an improvement of the novel transplanting mechanism of the rice transplanter, the rocker arm is connected with the transplanting box through a bolt.

Compared with the prior art, the novel transplanting mechanism of the transplanter has the following beneficial effects:

1. the driving mechanism in the transplanting box drives the crank to rotate inwards anticlockwise from top to bottom at a constant speed, the transplanting claw forms an inner circular motion curve so as to realize quick seedling taking and transplanting, after the seedling is transplanted, the driving mechanism in the transplanting box drives the crank to rotate outwards anticlockwise from bottom to top at a constant speed, the transplanting claw forms an outer circular motion curve, the transplanting claw is stably and slowly separated from soil so as to avoid taking seedlings inserted into the soil upwards, so that the effects of quick seedling taking and transplanting of the transplanting claw and slow and stable return of the transplanting claw are realized, the angular speeds of the transplanting claw are the same because the rotating speed of the driving mechanism in the transplanting box is constant, the driving distance of the inner circular motion is shorter than the moving distance of the outer circular arc, and the seedling taking and transplanting speed is higher than the seedling starting return speed under the condition that the angular speeds of the transplanting claw are the same;

2. in the prior art, the rotary box is utilized to drive the transplanting claw to rotate, the rotary box is internally provided with a complex gear structure which is easy to lock due to foreign matters, and the crank-rocker mechanism has a simple structure and is difficult to have faults such as locking and the like.

Therefore, the invention has the characteristics of reasonable structure, convenient use and the like.
