Description

TECHNICAL FIELD

[0001] The application relates to a rice transplanter and belongs to the technical field of agricultural machinery. BACKGROUND

[0002] In the planting process of crops, mulching is a very important link. The mulching of the ground film can make the soil fully absorb the light energy of the sun, improve the ground temperature, prevent early soil moisture loss, and promote the transformation of soil nutrients. The light waves emitted by the sun can smoothly penetrate the plastic film. The ground radiation light waves are long waves, which are not easy to penetrate the film and reflect into the atmosphere, so they can convert solar energy into heat energy and retain it in the soil. Because the film has a heat preservation effect, it slows down the rate of soil temperature drop at night. This is the familiar "greenhouse effect". Mulching the farmland with the ground film reduces soil water evaporation and also has the effect of water storage and soil conservation.

For example, the fixed connection selects the welding connection, and the detachable connection selects the hinge connection.

The mulch film paving and pressing edge device is installed on the mulch film paving. The edge collecting and pressing roller 34 turns the edge of the unfolded organic biomass mulch into the soil, so that the laid mulch is more like a newly made seedbed. The transplanter can be well used in the seedbed, and the influence of the spring wind on the mulching operation in spring is well solved. If a hard object in the soil is encountered, the edge collecting and pressing roller 34 can also rotate circumferentially with the installation arm 32.
