Technical Field

The invention relates to the field of floating disc seedling culture, in particular to a semi-automatic continuous seeder and a use method thereof.

Background

With the development of modern agriculture, in order to reduce the growth time of crop fields and intensively utilize land, light, temperature and the like, more and more agricultural production starts to grow seedlings by seedling trays and then transplants the seedlings to the fields. The full-automatic seeding machine popularized in recent years greatly improves the efficiency of the link in the aspect of seedling raising and seeding, but finds that the full-automatic seeding machine is not ideal by investigating the use condition of the full-automatic seeding machine in the seeding process, mostly idles in a warehouse and is abandoned, and most seedling raising workshops (bases) still widely use the most original manual seeding mode for seeding. The reason is mainly the following:

firstly, the full-automatic seeder has higher price, larger volume, difficult transportation, high storage difficulty, inconvenient maintenance and higher cost; secondly, the change of the specification of the seedling tray is difficult to change the parts of the full-automatic seeder; and thirdly, the single seedling growing points in the characteristic areas of hills and mountainous areas are small in scale, the seedling growing points are dispersed, and the service time is short, so most seedling growing bases still use the manual hole sowing method for sowing, the labor cost of the sowing link is increased, meanwhile, the manual sowing is realized, the sowing precision is unstable, the missed sowing and multicast conditions are common, the seedlings are not favorable for individual development after emergence of seedlings to form weak seedlings, and the difficulty and the cost of the thinning link are increased.

Disclosure of Invention

The invention aims to provide a semi-automatic continuous seeder to solve the problems in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme:

a semi-automatic continuous seeder comprises a top plate, a middle plate and a bottom plate, wherein a seed groove is arranged in the top plate, sieve holes are arranged in the middle plate, a blanking hole is arranged in the bottom plate, the middle plate is arranged between the top plate and the bottom plate in a sliding mode, and the blanking hole is slightly larger than the sieve holes; the bottom plate is characterized in that positioning plates are fixedly arranged on two sides of the short edge of the bottom plate and one side of the long edge of the bottom plate, and a driving assembly used for pushing the middle plate to slide is fixedly arranged on one of the positioning plates positioned on the short edge.

As a further scheme of the invention: the driving device comprises a connecting rod, an ejector rod and a movable rod, the connecting rod is horizontally placed, one end of the connecting rod runs through a positioning plate and a middle plate and is fixedly connected with the middle plate, the other end of the connecting rod slides and is hinged to one end of the ejector rod, the other end of the ejector rod is slidably hinged to one end of the movable rod, the other end of the movable rod runs through the positioning plate and extends out of the positioning plate, a fixed rod is hinged to the middle of the ejector rod, the other end of the fixed rod is fixedly installed on the positioning plate, a reset spring.

As a further scheme of the invention: the top plate is formed by arranging a plurality of rows of isosceles triangular rods, the periphery of the top plate is fixed by baffles, and a seed groove is formed between two adjacent rows of isosceles triangular rods.

As a further scheme of the invention: the diameter of the sieve pore is larger than the maximum seed diameter and smaller than 1.7 times of the minimum seed diameter.

As a further scheme of the invention: the middle plate and the bottom plate are made of plastic.

As a further scheme of the invention: the top plate is made of stainless steel.

A use method of a semi-automatic continuous seeder comprises the following steps: when the movable rod is in the normal position, the sieve mesh of intermediate lamella corresponds the kind seed groove of roof, the seed falls into in the sieve mesh because gravity is automatic, when the seedling tray is inserted by the disseminator below, promote the movable rod, make the intermediate lamella remove through the connecting rod, unnecessary seed stays in kind of seed groove in the sieve mesh, the sieve mesh of intermediate lamella corresponds the unloading hole of bottom plate along with sliding, the seed falls to the seedling tray naturally, accomplish the seeding, when the seedling tray withdraws from, through the reset spring on connecting rod and the movable rod, make the intermediate lamella reset, sieve mesh on the intermediate lamella is corresponding with kind seed groove on the roof, accomplish a seeding circulation with this, reach continuous seeding with this.

Compared with the prior art, the invention has the beneficial effects that:

(1) by accurate sieve pore size, the seeding number of each hole can be accurately controlled; (2) in a common manual sowing mode, taking 200 holes/disc as an example, the sowing quantity per person per day is about 100 plus 150 discs, and the sowing efficiency is greatly improved by using the sowing device to sow seeds, and the sowing quantity per person per day is about 3000 discs; (3) the seeder can be made of common plastic advertising boards (middle board and bottom board) and stainless steel (top board), and can be made correspondingly according to the number and size of different floating tray seed holes; (4) light weight, small volume and convenient transportation.
