Abstract

The utility model relates to an alternated large and small double disc side lower seed and fertilizer separately applied furrow opener for a seeder, which is mainly composed of two discs respectively fixed on two bearing seats, two shaft sleeves installed at an upright post by two furrow opener shafts, a fertilizer guiding pipe and a seed guiding pipe, wherein, the diameters of the two discs are unequal, and the included angles are unequal; the fixed position of the two shaft sleeves are mutually cross, and the included angles are unequal; the edge of the small disc and the inner face of the big disc have a polymerization point E; the fertilizer guiding pipe is close to the big disc, and the seed guiding pipe is close to the small disc; a seed protecting plate made of flexible material is arranged between the fertilizer guiding pipe and the seed guiding pipe. The utility model causes fertilizer to go into deep ditch and seed to go into shallow ditch to realize seed and fertilizer to be separated at side lower, so the fertilizer burns the seed which is prevented. The utility model has the advantages of high utilization rate of the fertilizer and reliable use.

Description

The staggered two the next seed manures of disk side of sower size divide sowing and applying furrow opener

The utility model belongs to the agricultural mechanical field of seeding and fertilizing, and the seed manure of the staggered two disk sowing side lower deep placement chemical fertilizer of particularly a kind of sower size divides sowing and applying furrow opener.

Wheat seeder adopts the disk trench digging for many years, sowing is executed seed manure and is executed for mixing with layer colleague, this form not only makes quantity and the kind of using seed manure be restricted, and the chemical fertilizer of being executed directly contacts with seed or the distance is very near and the burning kind, cause the wheat disconnected ridge that is short of seedling, influence the wheat full stand and obtain high yield, especially in recent years promote fertilizer deep placement, wheat defective ejaculation amount seeding technique, the line-spacing of seed, the grain distance, the degree of depth requires to have accurately position, every strain wheat seeding will have impartial living space and standing area, this just uses the quantity and the new technical indicator of position proposition of seed manure for wheat cultivation, the requirement that seed manure mechanism has not satisfied new technology implementation is used in original sowing.

The purpose of this utility model is to provide a kind of compact conformation, use reliable, fertilizer efficiency availability height, operating cost is low, realizes that the even sowing, seeding nutriment in a fertilizer of seed manure executes, and forms different depth, the staggered two the next seed manures of disk side of the sower size of band divide sowing and applying furrow opener separately.

The purpose of this utility model is achieved in that the staggered two the next seed manures of disk side of a kind of sower size divide sowing and applying furrow opener, mainly be by two disks that are separately fixed on two bearing blocks, be installed in by two plough axles respectively that two axle sleeves of column and fertilizer guiding tube and grain conductor constitute, it is characterized in that two disk diameters differ in size, corner dimension does not wait; Two axle sleeve fixed positions interlace, angle β 1, α 1 differ in size; Roundel edge and big disk inner face have a congruent point E; Fertilizer guiding tube is near big disk, and grain conductor is near roundel; Be provided with the flexible material seeds protecting plate between fertilizer guiding tube and grain conductor.Axle sleeve angle β 1 is identical with big disk angle β size; Axle sleeve angle α 1 is identical with roundel angle α size.The big disk angle is little, and the roundel angle is big.Big roundel congruent point E and roundel gyroaxis are in the same plane.

The utility model compared with prior art has following good effect:

1. fertilizer is deeper than under the seed side 2-5 centimetre, solves the mutual multifuel combustion kind of a seed manure difficult problem, can satisfy the agriculture requirement that wheat cultivation is executed seed manure kind, quantity and position, and improves chemical fertilizer utilization ratio;

2. can satisfy the three-dimensional coordinate status requirement of wheat defective ejaculation amount sowing line-spacing, grain distance, the degree of depth, help the formation that wheat cultivation evenly goes out full stand and strong sprout;

3. realize that seed manure is evenly broadcast, the side lower seed manure gives, form different depth, band separately.

Structural design novel simple, compact, use reliably, operating cost is low, advantage such as is easy to apply, and for China's Wheat Production huge economic benefit, social benefit and ecological benefits is arranged.

Description of drawings

Fig. 1 is the front view of the utility model structural representation;

Fig. 2 is A-A among Fig. 1, B-B revolved sectional view.

The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment: consult Fig. 1, shown in Figure 2, the staggered two the next seed manures of disk side of sower size divide sowing and applying furrow opener, mainly are to be made of two

axle sleeves

6,11 reach and column 2 connects fertilizer guiding tube 1 and the grain conductor 7 that are separately fixed at two

disks

3,8 on two bearing

blocks

4,9 and be installed on the column 2 by two

plough axles

5,10 respectively.Described plough is to be linked on the plough pull bar of sower frame below by column 2, and two

disk

3,8 diameter do not wait, angle β, α differ in size; One big disk, 3 fixed bearing blocks 4 are installed on the axle sleeve 6 of below, column 2 terminations by plough axle 5, and this fixed hub 6 angle β 1 are identical with big disk 3 angle β; One roundel, 8 fixed bearing blocks 9 are installed on the axle sleeve 11 of opposite side top, column 2 termination by

plough axle

10, and 11 angle α 1 are identical with roundel angle α for this fixed hub; Described installation big disk 3 and roundel 8

fixed hubs

6,11 are individually fixed in column 2 lower end both sides, left and right bushing is asymmetric mutually before and after about in the of 6,11, angle β 1, α 1 are unequal, but the back is concordant substantially above two disk borders, the extended line that the axial line of this two

fixed axis

5,10 is vertical is crossing to have angle, after installing roundel 8 and big disk 3, and make roundel 8 edges and big disk 3 inner faces that one congruent point E be arranged;

There is fertilizer guiding tube 1 to be connected with column 2 in the space between

big roundel

3,8 behind the column 2 with grain conductor 7, fertilizer guiding tube 1 imports zanjon near big disk 3 with fertilizer, grain conductor 7 imports shallow ridges near roundel 8 with seed, 1,7 close grain conductor 7 sides of two conduits are provided with the seeds protecting plate 12 that flexible material is made, prevent spring, seed manure is thoroughly separated.

Be installed on the sower during work of the utility model plough, and grain tube is inserted grain conductor 7 lead kind, fertilizer delivering pipe is inserted fertilizer guiding tube 1 lead fertilizer, sower advances, the plough of being made up of

disk

3,8 buries, fertilizer is gone in the zanjon that big disk 3 leaves by fertilizer guiding tube 1, and seed is gone in the shallow ridges that roundel 8 leaves by grain conductor 7, and earthing is finished sowing side lower deep placement seed manure process.
