Abstract

The utility model relates to an aspiration type precision seeder for a small four-wheel tractor, belonging to agriculture seeding machinery. The seeding of the already present seeder of the same class is half precision; the already present seeder has the defects of seed cracking and dressing agent injuring. A blower is installed on the utility model in order to overcome the insufficiencies. Therefore, a seeding body is enabled to internally generate negative pressure which sucks seeds. The seeds are adsorbed onto eyelets of a seeding disc. When the seeds are rotated to the lower part of the seeding body, the negative pressure is ended. The seeds fall into a seedbed which is prepared by a core plough share type double sliding knife guard plate colter. Therefore, fixed-point, positioned and quantitative seeding is achieved. The utility model can carry out double row seeding or single row bunch planting on ridges, seeding on the ridges and the work of flat planting and ridge forming.

Description

The tractor with small four wheels air-suction type accurate sower

What the utility model proposed is a kind of tractor with small four wheels agricultural seeder machinery.

Existing tractor with small four wheels sower, its sowing parts mainly contain level unit dish and vertical indent type, under the situation of seed size inequality, all exist the shortcoming of cracking seed and damage kind of clothing agent between the teeth, in order to reach the strain number of keeping a full stand of seedings, often artificial increase seeding quantity, and wasted elite seed.The existing small-sized precision sower that is referred to as is actually half-precision seeding machine.Sowing can not fix a point, locatees, quantitatively, vertically grain can only reach about 0.5 apart from the coefficient of variation.Exist the waste breeding, be unfavorable for promoting seed dressing clothing agent new technology, influence grain yield.

The purpose of this utility model is to overcome the deficiencies in the prior art and proposes a kind of tractor with small four wheels air-suction type accurate sower, do not crack seed in the sowing between the teeth, it is zero that wound is planted, but the also vernalization sowing of part crop, the agent of injuring-free seed clothing helps promoting seed dressing clothing agent new technology.The sowing depth unanimity, fixed point, location, quantitatively sowing are saved a large amount of elite seeds, increasing both production and income.

The technical solution of the utility model:

A blower fan is installed on the front beam of tractor with small four wheels, drive high speed rotating by the duplex pulley concial disk that is installed on the engine flywheel, air-breathing through air intake duct, making the sowing intracoelomic cavity produce the negative pressure suction plants, seed is adsorbed on the eyelet of seed tray, when seed forwarded the below of sowing body to, negative pressure finished, seed falls into the two sliding cutter backplates of core share type by deadweight and opens and wash in a pan in the kind bed that device leaves, and plants dark unanimity, little line-spacing is accurate.

Advantage of the present utility model and good effect:

The utility model has been equipped with advanced air-suction type accurate sower on the tractor with small four wheels of China's rural area recoverable amount maximum.It has injuring-free seed, and the agent of injuring-free seed clothing, but the also vernalization sowing of part crops such as corn can realize fixed point, location, quantitatively sowing, and vertically grain can reach about 0.2 apart from the coefficient of variation, saves seed.This machine is equipped with the seed tray of different hole counts and changes the sprocket wheel of the different numbers of teeth, can carry out double row sowing or single file bunch planting on the ridge of multiple pill shape seed, can satisfy the requirement of the various spacing in the rows of crops, can the ridge upper seeding wheel, and also can the operation of flat planting making ridge.

This machine can be finished dark pine, layer by layer manuring with once advancing, open multinomial agronomy operations such as washing in a pan sowing and earth backing suppression.

Below in conjunction with accompanying drawing the utility model is described in detail.

Blower fan 1 for centrifugal, impeller for radially bending enclosed, blower fan 1 is contained on the front beam of tractor, is driven by the duplex pulley concial disk that is installed on the engine flywheel, presses direction of arrow high speed rotating among Fig. 1, the process air intake duct is air-breathing, the interior generation of sowing body negative pressure is inhaled plant.Frame 2 is used for installing and fixing the various parts of sower and adjusts the ridge distance, and hangs, promotes or fall sower and carry out farm work by tractor hydraulic.Divide two Room in the seed manure case 3, cup dress chemical fertilizer, its underpart communicate with Deepling loosening soil and fertilizer applying device through the fertilising pipe.Broadcasting the broadcast fertile sprocket wheel of fertile sheave on left side land wheel 7 drives.Back chamber dress seed, in the discharging tube seed enters the seed chamber 10 of sowing body 9, the sowing sprocket wheel of seed tray 8 on right side land wheel 7 drives 4 rotations of sowing axle, and the sprocket wheel 12 that the intermediate chain wheel on the sowing axle 4 drives on the sowing body 9 rotates, and makes seed tray 8 by desired speed rotation sowing.Ploughshare divides three of left, center, right among Fig. 1, is fixed on the frame 2 with longeron.Be used for flat planting making ridge and ridge upper seeding wheel earth backing.The ridge roof pressure that the press wheel of afterbody is used for after planting is real.

Air-sucking type single-double-row seeder 5 comprises seed tray 8, sowing body 9, seed chamber 10, the clear fork 11 of planting, sprocket wheel 12 and strand kind of wheel 13, seed tray 8 inboards abut against on the C plane, sowing body 9 upper orifice link to each other with the air intake duct of blower fan 1, making sowing body 9 inner chambers produce the negative pressure suction plants, seed in the seed chamber 10 is attracted on the eyelet of seed tray 8, the seeds of inhaling were fallen clearly through the clear fork of planting more in 11 o'clock, each hole only keeps a seed on the seed tray 8, seed tray 8 rotates under the drive of sprocket wheel 12, seed on seed tray 8 eyelets turns to B end (see figure 3) by the A end by the arrow direction indication, when producing the B end, negative pressure finishes, and seed falls into the two sliding cutter backplates of core share type by deadweight and opens in the naughty groove of V-type that naughty device leaves.Plant dark unanimity, on same straight line.During double row sowing, seed tray 8 with holes all is equipped with in both sides on the ridge, realizes double rows line seeding on the ridge; During the single file sowing, a side is adorned seed tray 8 with holes, the blind dish sowing that the opposite side dress is not with holes, and will sow body 9 and laterally adjust to suitable line-spacing, can carry out single file drilling or single file bunch planting.Strand kind of a wheel 13 is to make with rubber, and seed tray (8) is fitted together, and rotation synchronously is built on stilts toward falling the influence sowing to prevent seed.

The two sliding cutter backplate ploughs 6 of core share type comprise side plate 14, backplate 15 and sliding cutter 16.

Backplate 15 is welded on side plate 14 and the sliding cutter 16, and side plate 14 is to prevent that when seed falls the wind seed from falling partially, and it opens sliding cutter 16 at the core ploughshare and wash in a pan two V-grooves of extrusion on flat that device leaves.Backplate 15 can effectively prevent seed fall into V-type wash in a pan trench bottom before, in the both sides soil, the sliding Hui Tao of soil block, the fall accuracy of kind of point of influence.Backplate 15 bottom opening width B are 1.2～1.5 times of seed width, can prevent that seed from blocking.
