Abstract
The utility model discloses a V-shaped packing wheel used for a plough-free deep-loosening layered-fertilizing precision corn sowing machine. A rocking handle is arranged at the upper end of a supporting rod, the lower end of the supporting rod is connected with a guiding rod inclined backwards, pressing wheels are respectively fixed on two sides of the lower end of the guiding rod through two wheel shafts, the space length between the upper ends of the pressing wheels is large, the space length between the lower ends of the pressing wheels is small, and the pressing wheels are symmetrically distributed in a V-shaped manner. The V-shaped packing wheel has the advantages of long service life, no earth sticking during the operation, and achievement of better depth limitation, packing and water furrow filling functions.
Description
Technical field
The utility model relates to field of agricultural machinery, relates in particular to the no-tillage subsoiling layer by layer manuring of a kind of corn precision seeder V-arrangement press wheel.
Background technology
Corn is no-tillage subsoiling layer by layer manuring precision seeder can operation in the situation that has stalk to cover, and finishes the operations such as subsoiling, layer by layer manuring, simple grain precision drilling, earthing, suppression with once advancing.Owing to adopt no-tillage seeding, can reduce cleaning stalk and whole ground link, reduce production costs, stalk rots to field, and increases soil organic matter content, retains and conserve soil moisture the effect of drought-relief, waterlogging-preventing; The subsoiling sowing, subsoiling more than 25 centimetres can be broken hard for many years tillage pan, and water conservation, fertilizer conservation and well developed root system strengthen absorbing capacity; The bucket wheel seeding mechanism single grain fine sowing is adopted in the simple grain precision drilling, emerge neat, the seedling gesture is strong; Layer by layer manuring need not to topdress, and improves significantly fertilizer efficiency.
But, present corn is no-tillage, and still there is certain technical deficiency in subsoiling layer by layer manuring precision seeder in operation process, be that press wheel generally adopts metal wheel, processing is trouble comparatively, easily get rusty, the life-span is short, easy clay and take turns wide can't the adjusting when operation, do not have the preferably effect of depth stop, suppression and flat moisture in the soil, affect the emergence rate of corn.
The utility model content
For overcoming above-mentioned technical problem, it is a kind of simple in structure that the utility model provides, long service life, and the suppression effect is good, takes turns the no-tillage subsoiling layer by layer manuring of wide adjustable corn precision seeder V-arrangement press wheel.
For realizing above-mentioned technical purpose, the utility model is realized by the following technical solutions: a kind of corn is no-tillage subsoiling layer by layer manuring precision seeder V-arrangement press wheel, comprise a support bar, post upper is provided with rocking handle, the lower end connects sweptback guide post, both sides, guide post lower end are fixed with respectively pinch roller by two wheel shafts, and two pinch rollers upper end spacing is large, the lower end spacing is little, and it is symmetrical to be in the shape of the letter V; The wheel body of described pinch roller adopts engineering plastics to make, and the wheel body outer ring sleeve has rubber ring; The position of two pinch rollers on wheel shaft is adjustable, and namely the press wheel overall width is adjustable.
The utlity model has following beneficial effect: during installation, support bar is fixed in the axle sleeve of the no-tillage subsoiling layer by layer manuring of corn precision seeder tail end, can regulate the terrain clearance of press wheel by rocking handle, two pinch rollers are V-shaped, the wheelspan of two pinch rollers can be regulated according to surface state, better depth stop, suppression and flat moisture in the soil effect can be played; Wheel body adopts engineering plastics, long service life, and wheel face adopts elastomeric material, and clay not during work can be given full play to its effect.

Among the figure, 1, rocking handle, 2, support bar, 3, guide post, 4, wheel shaft, 5, pinch roller, 6, rubber ring, 7, wheel body.
Embodiment
Shown in accompanying drawing 1,2, support bar 2 upper ends are provided with rocking handle 1, and the lower end connects sweptback guide post 3, and both sides, guide post 3 lower end are fixed with respectively by two wheel shafts 4 that pinch roller 5, two pinch rollers 5 upper end spacings are large, the lower end spacing is little, and it is symmetrical to be in the shape of the letter V; The wheel body 7 of described pinch roller 5 adopts engineering plastics to make, and wheel body 7 outer ring sleeves have rubber ring 6; Two positions of pinch roller 5 on wheel shaft 4 are adjustable, and namely the press wheel overall width is adjustable.During installation, support bar is fixed in the axle sleeve of the no-tillage subsoiling layer by layer manuring of corn precision seeder tail end, the terrain clearance that can regulate press wheel by rocking handle 1.
Claims (2)
1. the no-tillage subsoiling layer by layer manuring of corn precision seeder V-arrangement press wheel, comprise a support bar, it is characterized in that: post upper is provided with rocking handle, the lower end connects sweptback guide post, both sides, guide post lower end are fixed with respectively pinch roller by two wheel shafts, two pinch rollers upper end spacing is large, the lower end spacing is little, and it is symmetrical to be in the shape of the letter V.
2. the no-tillage subsoiling layer by layer manuring of a kind of corn as claimed in claim 1 precision seeder V-arrangement press wheel is characterized in that: the wheel body of described pinch roller adopts engineering plastics to make, and the wheel body outer ring sleeve has rubber ring.
