Seedling pusher for walk-behind rice transplanter

Abstract

A rice seedling pushing device of a walking type rice seedling transplanter comprises a rice seedling pushing rod and a push claw, wherein two downward lug plates are symmetrically arranged at the lower end of the rice seedling pushing rod, a gap allowing the push claw to be placed is formed between the lug plates, the rear part of the push claw is connected with the two lug plates through a rotating shaft perpendicular to an axis of the rice seedling pushing rod, a driving seat is arranged at the rear end of the push claw, and an extension spring driving the push claw to reset is arranged between the upper part of the rice seedling pushing rod and the rear end of the driving seat. In the high-speed rice seedling transplantation process, the rice seedling pushing action becomes very gentle and damage to rice seedlings due to rigid contact is avoided through gradual contact of the push claw with soil blocks with rice seedlings as well as structure buffer and in combination with the function of a soft material layer, the push claw is downwards and obliquely arranged under the action of water after rice seedling transplantation is completed, the adsorption force of water to the push claw is reduced, the well transplanted rice seedlings are prevented from being taken out in the push claw backing process, the rice seedling transplantation quality is improved, and the rice seedling pushing device is reasonable in design, simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to a walk-behind rice transplanter, in particular to a pusher for the walk-behind rice transplanter. Background technique [0002] During the transplanting process of the existing walk-behind rice transplanter, an appropriate amount of soil with seedlings is first grabbed by the needle and moved to the lowest point, and then the soil with seedlings is pushed to the field at high speed through the action of the pusher to complete the transplanting. . Since the existing seedling pusher is an L-shaped structure that is fixedly connected by the pusher rod head and the pusher claw, after the soil block with seedlings is inserted into the ground during the high-speed seedling pushing movement, the pusher moves backwards. In the middle, under the force formed between the push claw and the water, between the push claw and the upper part of the seedling, the soil block with seedlings will be pulled out from the soil, and the seedlings wil...

Problems solved by technology

Since the existing seedling pusher is an L-shaped structure that is fixedly connected by the pusher rod head and the pusher claw, after the soil block with seedlings is inserted into the ground during the high-speed seedling pushing movement, the pusher moves backwards. In the middle, under the force formed between the push claw and the water, between the push claw and the upper part of the seedling, the soil block with seedlings will be pulled out from the soil, and the seedlings will have low adhesion to the ground, and the phenomenon of floating seedlings will appear In severe cases, under the action of wind, the whole plant may be inverted in muddy water or the seed plant may be displaced, resulting in uneven transplanting.
