Walking transplanter with adjustable transplanting depth based on gear transmission principle

Abstract

The invention relates to the technical field of agricultural machinery, in particular to a walking transplanter with adjustable transplanting depth based on gear transmission principle, which comprises a main support; a wheel disc is movably connected inside the main support; paddles are movably connected to the outer side of the wheel disc; a holder is fixedly connected to the outer side of eachpaddle; a transmission wheel is movably connected to the front of the wheel disc; a driven disc is movably connected to the right of the main support; a moving pawl is movably connected to each of thefront and back of the main support; a limiting seat is movably connected to the right side of the main support. The walking transplanter with adjustable transplanting depth based on gear transmissionprinciple has the advantages that the rotational amplitude and rang of an inner transmission shaft of a driving gear I can be changed through the gear transmission principle, namely through the contact of the transmission gear with the driving gear I, driven gear I and driven gear II having different sizes, and therefore, the travel of each moving pawl is changed, and the transplanting depth of the walking transplanter is adjustable.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a walking rice transplanter which can adjust the depth of rice transplanting based on the principle of a gear transmission. Background technique [0002] Existing walking-type manual rice transplanters generally use the driving force of the soil on the runner to drive the runner to rotate, and then drive the eccentric wheel connected to it to rotate synchronously through the runner. The outer side of the eccentric wheel is provided with a rotating shaft. Connected with the rotating shaft, the continuous rotation of the eccentric wheel drives the movable claws to make periodic up and down reciprocating movements, and then the seedlings are inserted into the soil, but because the connection between the eccentric wheel and the rotating shaft is relatively fixed, that is, the cycle of the eccentric wheel driving the rotating shaft It is fixed, so that the stroke of the...

[0002] Existing walking-type manual rice transplanters generally use the driving force of the soil on the runner to drive the runner to rotate, and then drive the eccentric wheel connected to it to rotate synchronously through the runner. The outer side of the eccentric wheel is provided with a rotating shaft. Connected with the rotating shaft, the continuous rotation of the eccentric wheel drives the movable claws to make periodic up and down reciprocating movements, and then inserts the seedlings into the soil, but because the connection between the eccentric wheel and the rotating shaft is relatively fixed, that is, the cycle of the rotating shaft driven by the eccentric wheel Fixed, so that the stroke of the movable claw can not be adjusted when it reciprocates left, that is, the depth of the movable claw to insert the seedling into the soil is fixed, but in the actual transplanting process, the depth of transplanting should be adjusted according to the hardness of the soil. The higher the hardness of the soil, the shallower the depth of rice transplanting, and the lower the hardness of the soil, the deeper the depth of rice transplanting. Therefore, the existing walking rice transplanter cannot be applied to different soil hardness.
