Description
Technical field
The invention provides a kind of steering-wheel type cavitation disseminator with moving and stable vanes, belong to agricultural machinery technological field.
Background technology
Existing scientific research or product type Mulching and hill-drop sowing machine, mainly form by duckbilled cave opener, roller, kind case, grain conductor, seed plate, grain tube etc., the seed of wherein planting in the case enters the seed plate inner chamber through grain tube, when walking roller drives the seed plate rotation, seed is under the effect of gravity and centrifugal intertia force, be introduced into capsule kind district filling kind of a district, nest aperture in entering immediately.In the seed plate turning course, by the deadweight landing, the quantitative seed that enters inner hole is sent in the seeds protecting plate the unnecessary seed in capsule kind district in the clear district of planting.Protecting kind of a district, seed enters the duck-beak type cave opener through conduit, and the duckbilled of rolling is got hole and firming cavitation with mulch film earlier.When the duckbilled of activity was opened by the effect of soil, seed fell into the hole, cave, finishes out the bunch planting kind.This duckbilled opening ways is a front open type, and the seeding mode is the secondary seeding.The subject matter that exists is: 1, bad adaptability, only be applicable to sandy loam, and influenced by soil regime too big because indenting tool is charged seed, and when consistency of soil was big, folder soil also caused with Louing and plants, and 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, indenting tool 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, charge seed accurately, no hole, adaptability steering wheel type strong, excellent working performance move and decide the lobe dibbler.Its technical scheme is specifically:
A kind of steering-wheel type cavitation disseminator with moving and stable vanes, comprise seed wheel and the radial a plurality of indenting tools that evenly are installed on the seed wheel, wherein seed wheel comprises the cam that is fixedly mounted on the wheel shaft, be fixed on wheel disk cover on the cam and bearing holder (housing, cover) and be contained on the wheel shaft wheel disc that can rotate around wheel shaft, wheel disc is on the end face of cam, fix an endless belt around the outer ledge of wheel disc, the wheel disk cover is fastened on the endless belt and constitutes ring-shaped cavity with wheel disc, seed inlet is arranged on wheel disc and covers, correspondence is communicated with its ring-shaped cavity, it is characterized in that: each indenting tool includes the moving vane that cross section is the groove shape, decide lobe and spring and bearing pin, moving vane and decide the lobe groove and be installed on the endless belt in opposite directions, wherein deciding lobe is radial and is fixed on the endless belt, the inner flushes with the inwall of endless belt, cut sth. askew in the outer end, endless belt is passed in the moving vane gap, cut sth. askew in the inner and cam contacts, the outer end establish one with decide the consistent baffle plate of lobe outer end mis-cut angle, cut sth. askew and decide the closed formation of lobe discharge duckbilled in the moving vane outer end that is provided with baffle plate, moving vane is established a horizontal case away from the back side of deciding lobe, the bearing pin horizontal clearance passes sleeve pipe, one end is fixed on the wheel disc, the other end is fixed on the endless belt, spring is near the inner of moving vane and the back side that bearing pin is located on moving vane, spring one end is connected with the inner of moving vane, the other end is fixed on the wheel disc, moving vane can rotate around bearing pin, and ring-shaped cavity is partitioned into some fan-shaped cavitys.
Described steering-wheel type cavitation disseminator with moving and stable vanes, the passage oblique outward flange of taking turns disk cover of seed inlet in the wheel disk cover.
Described steering-wheel type cavitation disseminator with moving and stable vanes, the angular range of cutting sth. askew in the moving vane outer end are 30 °～40 °.
Its operation principle is: during work, seed wheel rolls on the ground with the sowing unit, seed is in seed inlet enters each fan-shaped cavity, when certain fan-shaped cavity forwarded the blanking position to the rotation of wheel disc, the seed in the fan-shaped cavity entered in the moving vane groove of indenting tool, when this indenting tool inserts soil and arrives desired depth, its moving vane the inner is conflicted by cam curved surface, and then the control moving vane rotates around bearing pin, so just utilizes lever principle to open the duckbilled of closure is mandatory, and seed falls into the cave from duckbilled.Along with the rotation of steering wheel, this moving vane begins to fall after rise along cam curved surface, and moving vane bounces back under the effect of spring, and the moving vane outer end is turned round in the other direction around bearing pin, and duckbilled is closed by force, finishes a cavitation, sowing cycle.This device is finished the input of seed successively by the switching of control duckbilled.
The present invention compared with prior art has following advantage:
1, deposits fan-shaped cavity, cam, indenting tool, the duckbilled jettison system of planting owing to having designed, this system can be when the indenting tool assembly inserts soil and arrives desired depth, mandatory duckbilled is opened, and has possessed to throw function in mandatory, it is fertile accurate, reliable to charge seed, throw, no hole.
2, by moving vane, decide the indenting tool that lobe, back-moving spring, bearing pin constitute, constitute steering wheel with wheel disc and the endless belt that is fastened on the wheel disc, moving vane can load and unload, and no matter is to install, adjust, still maintenance is all very convenient.
3, structure is simple and clear, attractive in appearance, do not press from both sides soil, do not press from both sides film, there are not knifing, dyestripping problem, can adjust sowing depth by adjusting bracket height, satisfy the bunch planting agriculture requirement fully, the operation quality height, stable and reliable for performance, can be adapted to the plastic mulching bunch planting mechanization demands of economic crops such as peanut, corn, cotton, garlic, wheat and cereal crops widely.
