Abstract

The present invention provides a steering wheel type cavity forming seeding device which comprises a seeding wheel. The present invention is characterized in that the seeding wheel comprises a wheel shaft, a cam, a wheel disc cover and a steering wheel, wherein the cam is fixedly connected with the wheel shaft by a key; the steering wheel comprises a wheel disc glidingly arranged on the wheel shaft, two circles of ring belts bulged on the wheel disc and a plurality of soil entering device assemblies which are radially and uniformly arranged on the ring belts, wherein the ring belts are uniformly divided into a plurality of sectors by the soil entering device assemblies; the wheel disc cover is fixed to the cam, and the sectors are sealed and covered to form a plurality of seed division cavities with fan-shaped cross sections; a fixed position of the wheel disc cover is provided with a seed falling opening so that the seed division cavities are communicated with the seeding device. Because of using a cavity forming seeding system composed of the cam, a slide block and the soil entering device assemblies and a system for continuously supplying seeds, dividing the sectors, dividing seeds and charging seeds in a cavity forming mode, the seeding device has the advantages of accurate and reliable seed division and seed charge, no cavities, no soil clamping, no film clamping, convenient installation, convenient maintenance and good performance, and can regulate the seeding depth by regulating a device frame.

Description

Steering wheel type cavitation seeder

Technical field

The invention provides a kind of steering wheel type cavitation seeder, belong to agricultural machinery technological field.

Background technology

The subject matter that existing scientific research or product type Mulching and hill-drop sowing machine exist is: 1, bad adaptability, only be applicable to sandy loam, charge seed that influenced by soil regime too big owing to go into earthenware, when consistency of soil is big, folder soil also causes Lou and plants, shedding motion is stained with to make with local methods and is become not reach sowing depth, causes Lou kind, hole, is short of seedling; 2, brush seed sorting mechanism principle backwardness, secondary divide kind of a low precision, poor reliability; 3, sowing depth is non-adjustable; 4, go into earthenware shedding motion easily tore film.

Summary of the invention

The purpose of this invention is to provide a kind ofly can overcome above-mentioned defective, divide kind, cavitation is charged seed reliably, the steering wheel type cavitation seeder of function admirable.Specifically:

Comprise seeding wheel, it is characterized in that: seeding wheel comprises wheel shaft, cam, wheel disk cover and steering wheel, its cam is fixedlyed connected with key with wheel shaft, steering wheel comprises two circle endless belt of the wheel disc that is slidingly mounted on the wheel shaft, wheel disc upper process and radially evenly is arranged on a plurality of on the endless belt and goes into the earthenware assembly, a plurality ofly go into the earthenware assembly endless belt is divided into some sectors, the wheel disk cover is fixed on the cam, each sector of capping forms some sector crosssections and divides kind of a chamber, one fixed position of wheel disk cover is provided with kind of a mouth, and branch kind chamber is communicated with seeding unit.

Described steering wheel type cavitation seeder, go into the earthenware assembly and comprise slide block, spring, push rod, outer sleeve, inner sleeve, wherein outer sleeve is fixed on the endless belt, inner sleeve is sleeved in the outer sleeve, both have on the position between two endless belt to minute groove of kind chamber one side, and spring housing is contained on the push rod, and an end of push rod is fixedlyed connected with slide block, its other end passes the outer sleeve end fixedlys connected with the inner sleeve end, and slide block is pressed close to cam.

Described steering wheel type cavitation seeder, the outlet of inner sleeve is duckbill.

Its operation principle is: wheel shaft is fixed on the frame, and cam is fixedlyed connected with key with wheel shaft, and wheel disc is slidingly mounted on steering wheel can be rotated around wheel shaft, and the wheel disk cover is fixed on the cam motionless.During work, steering wheel rolls under to the reaction force of going into the earthenware assembly on the ground at the traction of frame and soil, when each minute kind chamber on the wheel disc forwards kind of mouth place to, fall into branch kind chamber by the seed under the continuous row of seeding unit, the duckbill of promptly going into the earthenware assembly along with the rolling of steering wheel exports, and when this inserted soil arrival desired depth into the earthenware assembly, slide block began along cam to climb, through its duckbill outlet of depression bar jack-up inner sleeve positive opening, seed is dropped in the cave.Along with the rolling of steering wheel, this is gone into the earthenware assembly and is unearthed, and its slide block falls after rise at the effect lower edge of spring cam curved surface, and inner sleeve is regained, and closes the duckbill outlet.Respectively go into the earthenware assembly and repeat above-mentioned work with the rolling of steering wheel, formation is worked continuously.

This seeder compared with prior art has following advantage:

1, sows system owing to designed cam-slide block-push rod-two sleeve cavitation, this system can be when going into earthenware assembly insertion soil arrival desired depth, mandatory internally with inner sleeve jack-up, open duckbill outlet seeding, possessed the function of charging seed in mandatory, charge seed accurately, reliably no hole.

2, designed continuous for kind, divide to distinguish kind, cavitation is charged seed system, the endless belt that utilize wheel disc cleverly, go into the earthenware assembly, wheel disk cover and wheel disc covers, portion has constituted fan-shaped branch kind chamber within it, make seed that Continuous Flow falls by fan-shaped branch kind chamber through the groove branch into the earthenware assembly, divide kind, charge seed accurately.

3, no matter go into the earthenware assembly and be assembled in and constitute steering wheel on the wheel disc, can whole load and unload, be to install, adjust, and still keeps in repair all very convenient.

4, structure is simple and clear, attractive in appearance, does not have biofilm, dyestripping problem, can adjust sowing depth by adjusting bracket height, satisfies the bunch planting agriculture requirement fully, and the operation quality height is stable and reliable for performance.
