Problems solved by technology

[0003] The present invention solves the problem that the existing millet seeds are small, difficult to control when sowing, the sowing rate is large, and the efficiency is low. After emergence, a large number of artificial seedlings are needed, which restricts the large-area production of millet, and it is difficult to sow millet. Problem, a millet precision seeder is provided, and the specific technical scheme to solve the problem is as follows:

specific Embodiment approach 1

[0007] Specific implementation mode one: combine figure 1 , figure 2 , image 3 , Figure 4 and Figure 5 The present embodiment will be described. This embodiment consists of a ground roller 1, a ground roller shaft seat 2, a ground roller articulated column 3, a hydraulic suspension lower articulated pin groove 4, a funnel seed delivery pipe 5, a precision seed meter 6, a seed meter shaft 7, and a suspension column 8 , Pin groove 9 on the hydraulic suspension, seed box 10, frame front beam 11, opener assembly plate 12, disc opener 13, seed sprocket 14, transfer deceleration wheel set 15, ground roller chain Wheel 16, frame middle beam 17, frame rear beam 18, ground roller adjusting screw 19, ground roller traction frame 22, two side frames 23, long axis pin 24 and nut 25 are formed, and the frame front beam 11 is formed on the front end surface There are two articulated pin grooves 4 under the hydraulic suspension symmetrically, the upper articulated pin groove 9 of th...

specific Embodiment approach 2

[0008] Specific implementation mode two: combination image 3 and Figure 4 and Figure 5 The present embodiment will be described. The difference between this embodiment and the first embodiment is that it also includes a scraper 20 and a tension spring 21. The scraper 20 is arranged on the roller surface, and the scraper 20 is fixed on the roller of the ground roller 1 by the extension spring 21. On the surface, one end of the extension spring 21 is connected with the soil scraper 20, and the other end of the extension spring 21 is hung on the ground roller traction frame 22. Prevent ground roll 1 from sticking to dirt.

specific Embodiment approach 3

[0009] Specific implementation mode three: combination figure 1 , figure 2 , image 3 and Figure 4 The present embodiment will be described. The ground roller 1 described in this embodiment adopts an iron-skinned roller or a grid-shaped round roller.

[0010] work process:

[0011] When the tractor hangs the planter and drives forward, the ground roller 1 is driven to rotate, and the ground roller sprocket 16 rotates the large sprocket of the transfer deceleration sprocket set 15 through the chain drive, and the other small sprocket of the transfer deceleration sprocket set 15 passes through the chain The transmission drives the seeding sprocket 14 to rotate, drives the seeding shaft 7 to rotate, and impels the precision seed metering device 6 to accurately seed the seeds according to the walking distance, and the seeds are introduced into the small ditch opened by the disc opener 13 through the funnel seeding pipe 5 . It is rolled by ground roller 1. Sowing depth is r...

Abstract

The invention provides a precision millet seeding machine and relates to agricultural machinery, aiming at solving the problem that the seeding of millets is difficult. The precision millet seeding machine is composed of a suspension mechanism, a circular disc furrow opener, a precision seed-metering mechanism and a driving mechanism. A ground roller provided by the invention is a long roller, is compacted on the tops of two ridges once and has good stability; one-ridge single-row-width wide-width seeding is changed into one-ridge double-row seeding, so that production operation is convenient to realize; a line spacing can be changed randomly and is not influenced by the suspension mechanism; when the height of the ground roller is adjusted, the tightness and length of a chain can not be changed; the seeding depth is determined by a height difference between the bottom of the ground roller and the circular disc furrow opener, and the seeding depth consistency is good; the seeding machine is hydraulically suspended and driven by small-size and middle-size four-wheeled tractors, and wheels of the tractors move in opened furrows; the millets can be sowed in the two ridges for one time, and two rows of millet seeds, which have a distance of about 10cm, are sowed at the top of each ridge; the seeding depth is consistent and the seeding amount is accurate; and manual final singling is not needed after emergency of seedlings.

Description

technical field [0001] The invention belongs to the field of agricultural machinery manufacturing, and in particular relates to a millet precision seeder. Background technique [0002] At present, the seeds of millet are small, and it is difficult to control when sowing. Basically, they are sown manually, with a large amount of sowing and low efficiency. People pay attention to the 200710017665.3 patent "central drive strong push type and half-mouth precision seed metering device" and other technologies in the field of small seed seeding are relatively mature, but most of the existing supporting seeders are flat-planting models, which are difficult The problem of adapting to the demand for large-scale sowing on ridges in Northeast China. Contents of the invention [0003] The present invention solves the problem that the existing millet seeds are small, difficult to control when sowing, the sowing rate is large, and the efficiency is low. After emergence, a large number o...
