Power-driven transplanter

Abstract

The invention provides a power-driven transplanter, which belongs to the technical field of the agricultural machinery. The power-driven transplanter comprises a rack with travelling wheels, a driving motor on the rack, a storage cell, a deceleration chain wheel, a steering mechanism, a seedling guide tube, a transplanting motor and a transplanting mechanism arranged below the transplanting motor, wherein the independent driving motor and the independent transplanting motor are adopted; the driving motor drives the transplanter to move; the transplanting motor controls the transplanting action; after the transplanter moves for one planting distance forwards, the driving motor decelerates or stops; the transplanting motor drives the transplanting mechanism to downwards move by a crank movement mechanism to finish transplanting young seedlings; then, the transplanting motor drives a crank sliding block mechanism to move upwards; when a transplanting duckbill leaves soil, the driving motor drives the transplanter to move for the distance of one planting distance again to finish one working cycle. The power-driven transplanter has the advantages of simple structure, wide applicability, wide planting distance regulation range, small damage on a mulching film, good transplanting effect, high transplanting efficiency, low cost and the like, is reliable to work and is suitable for transplanting various plant young seedlings.

Description

technical field [0001] The invention relates to a motorized transplanting machine, in particular to an electric transplanting machine capable of transplanting crop seedlings on ridges after film spreading, and belongs to the technical field of agricultural machinery. Background technique [0002] After the seedling grows into a strong seedling in the nursery field, the seedling will be transplanted into the field to continue growing. For crops that need to be planted closely, the transplanting process is time-consuming and labor-intensive, which directly affects the work efficiency of transplanting. Simultaneously, seedling transplanting has a large difference due to irregular manual operation, which directly affects the growth of seedlings. Therefore, it is necessary to adopt mechanized means to transplant crops on the ridge after film spreading. [0003] The existing transplanting machines are mainly film transplanting machines, and they are all designed according to the...

Problems solved by technology

However, a large number of experiments have found that: due to the unevenness of the soil, the difference in softness and hardness, the forward movement speed of the walking mechanism is a random fluctuation, while the backward movement speed of transplanting is fixed, so the two are difficult to achieve. achieve matching

In fact, because the duckbill takes a while to emerge from the soil, the theoretical "zero-speed transplanting" is difficult to achieve the desired effect in practice.

When the land surface is not covered with film or the distance between plants is large, the above-mentioned defects are not obvious, but when plants with small distance between plants need to be planted on the land covered with film, the film will be torn, resulting in failure of transplanting; and, When planting plants with a large distance between plants on the film-covered land, even if the film is not torn, the opening of the film will be large, and the effect of moisture retention and moisture retention will be lost.

[0004] According to the "zero-speed transplanting principle", the transplanting mechanism of the existing transplanting machine on the film can only be designed as a mechanism that can make the duck's bill move in a curve, resulting in a curve in the movement track of the duck's bill in the soil, so that the plastic film Large opening, difficult to meet agronomic requirements

In addition, the existing film transplanting machines have complex structures and high costs, and all use internal combustion engines as power. The cost of fuel is high, it is difficult to promote the use of large areas, and it pollutes the environment, and it is difficult to use for some demanding crops.
