Disclosure of Invention

1. Technical problem to be solved

Aiming at the problems in the prior art, the utility model aims to provide the flexible steel cable for the seedling table of the rice transplanter, which can solve the problem of breakage caused by impact tension of the flexible steel cable after the seedling table is lowered, prolong the service life of the induction steel cable and improve the service efficiency of the machine.

2. Technical proposal

In order to solve the problems, the utility model adopts the following technical scheme.

One end of a flexible steel cable of the sensitivity of the seedling table of the seedling planting machine acts on the seedling table of the seedling planting machine, the other end acts on a control connecting rod of the seedling planting machine, and the lifting, the lowering and the neutral of the seedling table are determined by the different positions of the control connecting rod acting on the different positions to drive the lifting multifunctional valve.

The seedling stage can be instantaneously lifted through the hardness-sensitive stay wire arranged on the seedling stage central floating boat, and particularly when the field is in an uneven state, in order to avoid mud dragging of the floating boat, the seedling stage can act on the lifting position of the multifunctional valve through the sensitivity steel cable to drive the seedling stage to lift, so that the floating boat can smoothly pass through the uneven field.

When the seedling stage rises to the position that the floating boat is not in contact with the uneven field, the floating boat loses the acting force of the field, the floating boat rotates downwards around the hinging point under the action of self gravity, the sensitivity steel cable is in a loose state at the moment, the multifunctional valve is restored to a neutral position, and the seedling stage descends to the surface of the field.

The induction steel cable for determining the rising of the seedling stage pulls the hydraulic valve to work through the control rod, because the reaction time of the valve and the falling time of the seedling stage have time difference, when the seedling stage contacts the ground, the valve rod is not restored to the rising position, and at the moment, the weight of the whole seedling stage is born by the stay wire, so that the stay wire is easily broken, in the patent, a spring is arranged at one end of the induction steel cable, and the tension of the stay wire is balanced through the tension of the spring.

3. Advantageous effects

Compared with the prior art, the utility model has the advantages that:

(1) According to the scheme, the tension of the induction steel cable is buffered through the increased elastic joint, the problem of breakage caused by the impact tension of the sensitivity steel cable after the seedling table is lowered is solved, the service life of the induction steel cable is prolonged, and meanwhile, the service efficiency of the machine is also improved.
