Abstract

The utility model belongs to the technical field of wheat-seeding machine fittings and discloses a seeding pipe for a uniform wheat-seeding machine, which is mainly and technically characterized by comprising a seed-guiding pipe, wherein the seed-guiding pipe is communicated with a seed box, a uniform seeding pipe is connected to a position below the seed-guiding pipe, a rectangular seeding channel is positioned below the uniform seeding pipe, inclined seed-dividing sheets are arranged in the seeding channel, the seeding channel is divided into a plurality of seeding subchannels through the inclined seed-dividing sheets, and wheat seeds on an upper opening of the uniform seeding pipe fall along each seeding subchannel, so that the seeds are more uniformly seeded with consistent depth, the wheat yield is improved, and the seeding pipe for the uniform wheat-seeding machine is convenient to popularize.

Description

Wheat is all broadcast machine with the pipe of sowing

Technical field

The utility model belongs to the technical field of sower accessory, relates to wheat concretely and all broadcasts machine with the pipe of sowing.

Background technology

For improving the wheat per mu yield, adopt the evenly mode of sowing, at present, evenly sowing mainly contains following dual mode, one, earlier with wheat evenly on the surface of ploughing, with rotary tillage soil wheat seeds are driven underground, make the seed uniform broadcasting of whole wheatland, wheat yield increases significantly like this, but exist following scarce choosing to fall into, the one, whole wheatland does not have to be fit to fertilising, deinsectization, other working space such as intercropping, the 2nd, rotovator revolves cutter a small amount of wheat seeds is caused in various degree injury, and the 3rd, the wheat seeds that enter soil depth are deep mixed, and germination rate is affected and wastes seed; Its two, adopt and all to broadcast machine because existing the sow reasons in structure of pipe of machine of all broadcasting causes uneven sowing even, wheat yield improves not obvious.

The utility model content

The technical problem that the utility model solves just provides and a kind ofly sows evenly, the wheat of wheat seeds depth unanimity is all broadcast machine with the pipe of sowing.

For solving the problems of the technologies described above, the technical scheme that the utility model proposes is: comprise the grain conductor that kind of case is communicated with, below described grain conductor, be connected with and all plant pipe down, be the rectangle passage of sowing described all plant down below the pipe, be provided with oblique branch kind sheet in the described passage of sowing, the described oblique branch kind sheet passage of will sowing is divided into a plurality of subchannels of sowing.

Its additional technical feature is:

All plant inside pipe wall and be provided with many spiral ridges described grain conductor and following all the kind are connected with all kind pipes, are described between the pipe on, formation is gone up branch and is planted a passage between the adjacent spiral ridge;

The height of described spiral ridge is the 1.5-2 millimeter.

The wheat that the utility model provides is all broadcast machine with the pipe of sowing, compare with prior art and to have the following advantages: one, owing to comprise the grain conductor that kind of case is communicated with, below described grain conductor, be connected with and all plant pipe down, be the rectangle passage of sowing described all plant down below the pipe, in the described passage of sowing, be provided with oblique branch kind sheet, the described oblique branch kind sheet passage of will sowing is divided into a plurality of subchannels of sowing, wheat seeds fall at following each subchannel of sowing of pipe upper edge of all planting, feasible sowing is more even, depth unanimity has improved wheat yield, is convenient to promote; They are two years old, owing to be connected with all kind pipes between the pipe at described grain conductor and following all the kind, all plant inside pipe wall on described and be provided with many spiral ridges, form between the adjacent spiral ridge to go up and divide kind of a passage, the little wheat seeds that get off through grain conductor drop on different the branch in kind of the passage randomly, and come downwards to down along this branch kind of passage and all to plant in the pipe, make sow more even; Its three because the height of described spiral ridge is the 1.5-2 millimeter, can prevent effectively that little wheat seeds from entering another minute from branchs kind of a passage and planting a passage.

Description of drawings

Fig. 1 all broadcasts the structural representation of machine with the pipe of sowing for wheat;

All plant the structural representation of pipe under Fig. 2;

Fig. 3 is last structural representation of all planting pipe;

All plant the expanded view of pipe on Fig. 4.

Embodiment

Below in conjunction with accompanying drawing the wheat that the utility model proposed all being broadcast machine uses the structure of the pipe of sowing to be described further.

As depicted in figs. 1 and 2, all broadcast the structural representation of machine for wheat with the pipe of sowing.Its structure comprises and plants the grain conductor 2 that case is communicated with, grain conductor 2 can adopt corrugated hose, like this, when bending, be not easy to stop up, below grain conductor 2, be connected with and all plant pipe 3 down, it be circular all planting down the suitable for reading of pipe 3, is connected on the below of grain conductor 2, all plants down to manage 3 below and be the rectangle passage of sowing, sow and be provided with oblique branch kind sheet 4 in the passage 1, be provided with side in the pipe 3 and be in charge of 4 all planting down, oblique branch kind sheet 4 passage of will sowing is divided into a plurality of subchannels 5 of sowing, and wheat seeds fall at each subchannel 5 of sowing of upper edge of all planting pipe 3 down, feasible sowing is more even, depth unanimity has improved wheat yield, is convenient to promote.

As Fig. 1, Fig. 3 and shown in Figure 4, be connected with all kind pipes 6 at grain conductor 2 and between all kind manages 3 down, on all plant pipe 6 inwalls and be provided with many spiral ridges 7, form between the adjacent spiral ridge 7 to go up and divide kind of a passage 8, the little wheat seeds that get off through grain conductor 2 drop in the not the same branch kind passage 8 randomly, and all plant in the pipe 3 along should go up dividing kind of a passage 8 to come downwards to down, make sow more even.

The height of spiral ridge 7 is the 1.5-2 millimeter, can prevent effectively that little wheat seeds from entering another from a branch kind passage 8 and dividing kind of a passage 8.

Protection domain of the present utility model not only is confined to the foregoing description, and is identical with the tubular construction of sowing as long as structure and the utility model wheat are all broadcast machine, just drops on the scope that the utility model is protected.

Claims

1. wheat is all broadcast machine with the pipe of sowing, comprise the grain conductor that kind of case is communicated with, it is characterized in that: below described grain conductor, be connected with and all plant pipe down, be the rectangle passage of sowing described all plant down below the pipe, be provided with oblique branch kind sheet in the described passage of sowing, the described oblique branch kind sheet passage of will sowing is divided into a plurality of subchannels of sowing.

2. wheat according to claim 1 is all broadcast machine with the pipe of sowing, it is characterized in that: be connected with all kind pipes between the pipe at described grain conductor and following all the kind, all plant inside pipe wall on described and be provided with many spiral ridges, form between the adjacent spiral ridge to go up and divide kind of a passage.
