Abstract

The invention provides an inverted agraffe tubular type seed-separating machine for tiny seeds and belongs to the technical field of agricultural machinery. The purpose of the invention is to solve the problems that the seeding quantity is large and the seeding quantity is difficult to control when the tiny seeds are sowed by the existing seeding machine. The inverted agraffe tubular type seed-separating machine for tiny seeds comprises a seed taking slot, a seed buffer room and a seed diversion slot, wherein the seed buffer room is in tubular shape, one end is open and the other end is closed; seed discharge holes with the diameter of 2.0-5.0mm are opened in the tube wall of the seed buffer room near the open end, and are suitable for seeding tiny seeds such as foxtail millets, millets, chinese cabbage seeds, and rape seeds with the diameter of 1.5-4mm. The invention has the advantages that when a hole-type seeding machine is used for separating the tiny seeds, the number of discharged seeds can be selected for a seeding hole on the basis of the size of the seeds, the rate of emergence and the size of the seed discharge holes, so that not only the emergence rate can be guaranteed, but also the seeds can be saved, and moreover no thinning of the seeding is needed.

Description

Have contact with the small grain of tubular type seed seeder

Technical field

The invention belongs to agricultural machinery technological field, be specifically related to have contact with the small grain of tubular type seed seeder.

Background technology

Advocate accurate theory in modern times in the agricultural,, can under the situation of the not underproduction as far as possible, reduce agriculture production cost, effectively avoid the wasting of resources through implementing accurate operation; Precisely operation comprises precision drilling and smart amount fertilising, and existing seeding machinery has been realized precision drilling basically, has improved production efficiency greatly like the appearance of precision sowers such as corn, soybean, potato; But for fine particle such as cereal seed, diameter is about 2 millimeter, does not also have seed placing device preferably now.

Summary of the invention

The objective of the invention is to solve the problem that prior art exists, be provided for having contact with the small grain of tubular type seed seeder in the seeder.

The present invention solves the problems of the technologies described above the technical scheme of taking to be:

Have contact with the small grain of tubular type seed seeder, comprise and get kind of a groove, seed surge chamber and seed guiding gutter; It is characterized in that: said seed surge chamber in a tubular form, end opening other end sealing is contained in and gets kind of a trench bottom, its openend is gets kind of the inlet of groove seed, on seed surge chamber tube wall, has feed outlet near openend; Said feed outlet diameter is about 2.0～5.0 millimeters; Said seed water conservancy diversion flute profile is as having contact with, and its unhooking end is being got kind of the porch of groove seed and got kind of a groove and link to each other.

The present invention compared with prior art has following beneficial effect:

Because the present invention adopts the seed surge chamber that has feed outlet; Thereby when making the seeding of small-particle seed; 3～5,4～6,5～7,6～8,7～9,8～10,9～11,10～12 of seedings etc. can be selected according to the combination of seed size, percentage of seedgermination and feed outlet size in a kind cave, keep rational quantity; Both guaranteed that emergence rate also saved seed, and need not thinning.

Description of drawings

Fig. 1 is a structural front view of the present invention;

Fig. 2 is a structure vertical view of the present invention;

Fig. 3 is structure A of the present invention-A profile;

Fig. 4 is an installment state sketch map of the present invention.

Among the figure: 1-kind of a groove got; 2-feed outlet; 3-openend; 4-seed guiding gutter; 5-seed surge chamber; 6-seed; 7-duck bill hole.

Embodiment

Like Fig. 1, Fig. 2 and shown in Figure 3, have contact with the small grain of tubular type seed seeder, comprise and get kind of groove 1, seed surge chamber 5 and seed guiding gutter 4; Said seed surge chamber 5 in a tubular form, end opening other end sealing is contained in and gets kind of groove 1 bottom, its openend 3 is gets kind of the inlet of groove seed, on seed surge chamber 5 tube walls, has feed outlet 2 near openend 3; Said seed guiding gutter 4 shapes are as having contact with, and its unhooking end is being got kind of the porch of groove seed and got kind of groove 1 and link to each other.

Said feed outlet 2 diameters are about 2.0～5.0 millimeters.

The course of work:

When the present invention uses, as shown in Figure 4, be buckled on the duck bill hole 7 in the seeder having contact with the small grain of tubular type seed seeder, and fix it; With the cereal seed 6 of packing in the seeder, when seeder rotated, seeder rotated thereupon, at this moment; Cereal seed gets into the openend 3 of seed surge chambers 2 along guiding gutter 4, is rotated further, and the seed in the seed surge chamber 2 is with the quantity of design, as 6～8 etc.; Enter in the duck bill hole 7 by feed outlet 2, afterwards, along with duckbilled opens and by being broadcast in the soil.

Claims

1. have contact with the small grain of tubular type seed seeder, comprise and get kind of a groove (1), seed surge chamber (5) and seed guiding gutter (4); It is characterized in that: said seed surge chamber (5) in a tubular form; The sealing of the one end opening other end; Be contained in and get kind of a groove (1) bottom, its openend (3) is gets kind of the inlet of groove seed, on seed surge chamber (5) tube wall, has feed outlet (2) near openend (3); Said seed guiding gutter (4) shape is as having contact with, and its unhooking end is being got kind of the porch of groove seed and got kind of a groove (1) and link to each other.

2. the small grain of the tubular type seed seeder that has contact with according to claim 1, it is characterized in that: said feed outlet (2) diameter is about 2.0～5.0 millimeters.
